To all whom it may concern.'

Beit known that I, ISAAC Anims, of Boe ton,' in the county of Suffolk and State of Mas saohnsetts, have invented certain new and usefnl Improvements in Machinery for Printing; and I do hereby declarethat the same is fully described and represented in the following Sp'ecication and-accompanying drawings, letters, figures, and references thereof.

Theprinting-machine embodying my invention may be described ris made up of iivedii ferent systems or agigregations of parts, eachsystem being used or the performance of n.. distinct part of the process of printing-to wit, iii-st, the distribution of the ink; second, pointing the sheets on the feed-board or tympan; third, taking the sheets from thei'eedfboard and conveying them in between the ,platen and form of types;A iourthyproducng theimpression, and, fifth, removing the'slieetsfrom the press und .laying them ou the pile or a table or other convenience provided for'the purpose, each system ,being so calculated and arranged within. itself, and so arranged and combiuedwith all the others, that while each performs its oice in adistinct and .complete manner successively they all receive their appropriate motions from the same motive agent, and though some parte are in conetant operation, while other parte move and stop alternately, the said systems severally complete the performance proper to each 0l' them in cousecntive'order. e

The process of distributing e ink is performed by means of a system of rollers, as folf ows:

qdenoteaasection of theink-fountain. This is made upon the principle of those in 'common use, and is principally composed of a trough for thcink, a roller, and a sex-oper.

Its omoe is to take the ink from the fountain-roller and convey it to the distribution-cylinder w; Said feed-roller is mispended by pivots in hear: ings (one of which is'seen et ,.Fi 3) on the levers it, Figs. 1 and 3,'audit is ronght down in contact with the fountain-rollefdn. order to teke from it a portion of ink every person' 9 RX ne time an impression is given) .b v means of a to one endol' the roller-frame by incansof thc projection from each of two guidcpieces,"(one connecting-rod m'. y of which is seen at y, Fig. 1,) which are atn is n wei hted lever, which is attached to tached to the ends ol' the bed. Said projecthc cud of t ic rocker'shait L. tions, when the bedis raised up to produce o' is a dat spring, which is secured to the l an impression, come up under the ends of the frame d' by its lower end, while its upper end levers t t, and, by forcing said ends up;` canse is made to bear against n collar or, shoulder the opposite ends, with the roller suspended on the rocker-shalt i'. Its use is to press the on them, to move down until said roller is traveling roller against thc cylindcr w. 4 bron ht into contact with the fountain-roller, The diagonal or obliqucbcnringof thc travwhi imparts to it, along its whole length, a cling roller against the cylinder 10 is successmall quantity of ink. Whcn tho'bed is lowsively changed, as follows: Supposing the cylered dow'n, the weights of the levers t t(one inder w to be in motion and thc traveling ot which .weights is seen at z, Fig. 1)cause roller to be in contact with it. as shown in the feed-roller to rise up and come in contact Vthe drawings, Fig. 1., the said traveling roller with the distribution-cylinder w, upon the will advance toward4 one end of the cylinsnrlace of which the ink thus taken from the der until it shall have approached near to it, fountain will atterward be distributed by the when the lever n' will be brought in conrolling together of the perpheris of said tact with a projection which proceeds from cylinder and said roller. The cylinder w the lower part, q', Fig. 2, of th scroll, which should be sustained by its journals in boxes supports the parallel'rods, f' g. and is near so attached to the ends of the tivo side pieces the said end of said cylinder. The said pro. of the frame, Figs. 2 and 3,as to be adjustjection.- by means of the continued advanceable vertically by means of slots or otherwise. nient of the traveler toward and against it, Thel said cylinder receives constant rotary moelevates the said weighted lever n and forces tion from the -ily-wheel shalt by means of an it over, so as to throw its center of gravityl on endless band, which runs over the pulleys a the opposite side of 4the rocker shaft 1:', to on tbody-wheel shaft and b' on the shaft of the which it is attached.` The said wei hted lecylinder. ver in falling over will turn said roc er-shaft -In order to make a perfect distribution of in its bearing, and by so doing will elevate theV ink from end toend over the surface of the cross-piece I', und so as. to carry the pm the cylinder u, a short roller, c, (see both or screw 1, which goes through t-he slot x', Figs. 1 and`3, the latter ligure being a rear Fig. 8, made through the connection-rod m',

The said tivo rollers a' s' are suspended in the usual .mnnnerhy their journals, which are made to run in boxes properly fixed to the front part'ota 'sliding frame, .t', which I call the l'risket-carriagc. Fig. 9`denotes a top view of said carriage, the roller-boxes, and certain other paris attached toit, (see also Figs. 10 and 11,) which are rospectivclya top and side view ofoue-halfot a frlsket-carriage having certain other parts, to be hereinafter described, attached to it.

their said grooves being for-the frisketcarriage to slide in. When the impression is being produced, the position o`f the frisketcnrringe is such as to bring' the rollers s a'* in a central position o'n the cylinder io, whereon they lay and roll in contact with said cylinder during most o f the time' that the bed is in the act of rising and falling. By this means the ink is evenly communicated from said cylinder to the whole surfaces ol' the` rollers s n', 'the said rollers, by means of' a prope' move 'ment of the i'rislcet-earriuge. being afterward caused to roll entirely over the forni of types first from leltto right, and next back again to their places-on the V distribut-ionfcylinder w", thus rolling twice over the form. motion, of the frisket-carriage and the parts attached to it is'produeed hy means of the vertical levers or arms w w', (see Figs. 1 and 12,) which are attached to it by means of two connecting-rods, z', that are properly jointed to said arms-and to the 'armsprojecting from said carriage, as seen at g/ 3f in Figs. 1 and 9. The said arms or levers zo ip proceed upward from neareacli end ol' a transverse rocker-shait, z, which is supported in the-.machine bygudgeons a' n', Eig, 12, which are supported in bearings .b b', Figs. 2 and 3, made on the inner surfaces of the two side pieces oftheframe.

It may he seen that the crank-pin h stands o' sides-iso sonne-A what from the cranlepin j. This is for the purpose of timing the motion produced by the crank h with that produced by tho crank f'.

1,'den0tes an instrument which I ea lan alternator. Itisxed tothe rockershait o? near toits front end and in auch mauner as to receive in the eccentric slot or groove A, made through it, the frictlomroller i', Fig. 12, said roller being aixedtothe front arnyio,

This

and upon the projecting pin 7: thereofin such 4position and manner that when motion isglven to the rorkereshaft o' b the cxanlcand 'the in,` termedlate parts it wil cause the aforesaid-al' terhator tohave u reciprocating motion and curryl the roller t. through all parts of thesaid slot or eccentric groove h through orfin said alternator. This operation will givea regular und4 progressive motion to the rollers' the arms ww', and the 'l'risket-earriage, towhich they are attached, and will hold said n-rms and carl-lave still at and during the proper time, according as the direction of said slot in its dilleicnt parts' varies more pr less' from or coincides with the are ot'a circle whose'center is the center of the rocker-shaft c.

The alternator gis made to perform its oioe' as, follows: When the various operating parts ot' the machine occupy 'the positions in-whieh they 4are represented in Fig; i, the-friction` roller s" will be inthe upper extremity ofthe ,slot of the alternator, and the frsket-carriage and the two inkinglrollersa s"will he drawn totheir extreme limit ot' motion toward th'e right-hand end of the machine. Now,'supposing the machine in operation, the operating parts being situated as just mentioned, the moment the axis' of the crank h passes its lino of centers it will cansehy its operation ou the connecting-rod e and lever d* and rook! ing shaft c the alternator to begin its gmotion toward the left-hand end ofthe machine, which motion being continued causes the friction- 'roller 1", while moving along, withl the alter? nator and carryingwith it the arms ww' and the frisketourrriage and hiking-rollers c s', to descend gradually in the slot of the alternator unt-il its center reaches the dotted linel,where said slot begins to. be an are of a circle whose center is in the axis of the rocker-sbatte. rPhe motion thus producedto, this extent will have given the frisket-rringe' its entire Ino tion toward the left, and have brought the inking-rpllers l s to a ceutralposition on the distribution-cylinder w, where they remain and receive a distribution of ink.until the crank h shall have caused the alternator to perform the remaining partjof'its motion toward the lea, and a reversed motion such as to i carry the center ofthe roller i' again to the dotted line l. This having taken place. the-said roller will beginto rise toward the upper partof the slot of the alternator, and to movetoward'the righthand end of themachipe and carry with it the said arms,`frisket-carriage, and inkngrollers until these parte have all received their requisito motion in tlxat'direetion. On completion ol the same the crank h will again pass its said line of centers and; p`rodnce the motions inthc opposite direction, as before dei 4 l During the progress of the process of distrihntion the sheets to be printed must be snccessvely laid upon the tympan and pointed so as to make register; I t Iliefollowing is a description of the tympan and the parte' intended to govern the register:

4r Fizins per side `with a sheetfiron plate., i', which ex-:

ten'ds from endto end of said frame, and from its npper or right-hand edge down onto. the cross-bar 4*, thus constituting a regular inclined plane, upon which the sheets of paper to be printed are to be successively luid. Its lower ed restsnpon the top edges of the two sides oft c prua-frame. Its npper part is" supported by the gudgeons r.r, Fig. 13, which' rest in bearings in the upper ends ofthe standards s which are raised respectively above the upper edges of the two sides of the pressframe. (See Figs. l, 2,-and 3.) The tympan is thus suspended in order that it may beturned up nearly to n vertical position, so as to-n'lake room for-the platen to be moved on' from over the bed.

t' t, Fi 1,.denote small holes or cavities made in te inside edge or face oi' the further side piece, u', ofthe frame of the said tympan. These holes are made for the receptionof one end of a rod which it is necessary to pnt across the said tympan-frame for the purpose of snstaining the edges orlower parts of such sheets of paper as may be too wide for said tympan `without such or a similar provision.' The `end of said red which comes next tothe person who points thel sheets may be secured to the tympan by passing a pin through one of a number of holes made horizontally through the nearend rail of said tympan opposite t the holes l' t', said pin being made to enter hole drilled into the end of said rod. Thi 'mode of securing said rod is adopted in order that it may be changed conveniently and quickly from one place to another, or be taken out and dispensed with. according as circumstances ,may require. The sheets, after they have been pointed, are seized by nippers and dragged from the tympan in a manner yhereinafter to be described.

In order to prevent the tearing of the pal per sheets at the point-holes, itbecomes necessary for the points to be drawn down below the sheets have been fastened upon by said nippex's und n. momentbefore they begin to be moved from said tympan. This is performed, and the points again thrust ont successively,

l as follows: The points n u consist of small spindles, each of which is pointed at one end, .but otherwise-of uniform size, excepting -iu the middle, which is enlarged, and hasn groove turned or formed in it, the said groove being made to receive the forked end ot' one of two little levers, o u". z ir' denote stocks or frames which sustain the points and their levers. Each of the points rest and move np anddown vfreely through -two projections, :i

iliade upon the outer end ot' each of the said stocks. Each of the levers c go', which hun nie points ne operate said pollas, is secured toone of the said stocks by means of` a f ul'crum screw or pin, a', and each of the saidstoclcsis secured to the iron platefoftln tympan by a little scrcw-bolt, b, anda eontinlngmnt, c'. The inner ends oli t-hc lcvers`o"io' are brought together inthe `ccnteroi t-he tympan, where they are jointed to the cud u'of another bent'lever, e, whose fnlerm'ns or journals are sustained in bearings f. as seen in Fig. 18, ap; plied to thennder si e of the tympan-frame. The opposite end or arm ofthe bent lever passes down between the side piece of the pressframe andthe side ofthe frisket-carri 'e, asseen in,

Fig. 1, where it is operated .upo usfolloivs: 0n the side of the frsket-carriage isznix'eda. little cam, g, (see Fig. 9,) which i's so placed that when said carriage is in operation said cmn shall at the proper time pass under the end of the lower arm of the 4ever-4e and elevate it, which operation, through the action of the levers of w, will cause the pointsto project above the surface of the tympan, where thcywiil be'held the proper period of time by means of the spring h, Fi 2,-said spring being secured tothe inside o one side of the' prem-frame, and so placed that when said-arm is elevated as aforesaid said spring willspring out into or under a suitable notch made for the purpose .on the outer side of said arm. By means of another cam,

if, nixed to the side of. the frisket-enrriage, the sprin h is pressed back, so as to disengage the sei arm,

and allow it by its own'weight, or by the as' sistance of a'sprlng, to fall dowp,and thereby canse the points to be noved dow nwsrd below or even with the surface of the-tyxntgsn. The said cam i should be arranged on s frislretcarriageinsnch manner that it may aetuate the spring when the said carriage tix-st starts togo toward the left-hand end of the machine, and' this it-does by coming in contact with the stud, i k', projecting from the spring h'i- This cam consists of the beveled corner of asort of latch orclick so aixed .to the side of the carriage by means of 'a screw-pin at P that in its passage toward the rightlhand end of the ms- -chine it shall slip or slide'over the rejection by rising np 1n the manner f s -teh and slipping over, so as not to press said spring from under the notch which holds 'up the lever e?, and'so that the moment the beveled corner or cam has passed the said projection k it shall drop down snlcieiitly to Acome against said stndand press buck said spring, 'und by that means drop the points, when the carriage begins itsm'otion in the othe'r direction, as aforesaid. -It is sometimes necessary placed so as to range crosswisc ot' the sheet, and sometimes lengthwise or 'at right angles to the position indicated in the drawings. rlhe holes through the iron plates, therefore, through which the bolts bf pass to secure the polnt stocks to the tympan, are elongated into arcs of a'circle, as seen at P l,

Fig. 13, whose eenteris in the screw'or pin u',

` R ne 5 These slots permitthe point-stocks to be moved around in any necessary positiomto make registers crosswise or lengthwise of the sheet, as circumstances may require, without rendering it necessary to remove the bolts by which the said stocks are secured in their places, and withoutseparating the points or their stocks from the machinery which operates them or from the parts which hold them in their places. The four holes m' n o p, Fig. 13, which are made through the iron plate of`the tympan and for the points n n to project through, must also be made curved, and long enough to allow ofthe necessary variation ofthe points from central lines across the tympan. The sheets to be printed are successively laid by the attendant in a central position on the tympan above described. The points, having been tirst properly adjusted and secured in their places, so as-to produce register, are thrust through cach sheet by pressing the sheet down upon them.

The nippers which take the sheets from the tympan are constructed as follows: There should be several sets for each press, (two or more pairs in a set, as the lengthof the sheet may require,) each set di'ering in length from the others, according as' the sheets to be printed may vary in width one from another, the widest sheets requiring the shortest nippers, and the narrowest sheets requiring the longest ones. 4

q i, Fig. J, denote the nippers as they appear the moment before being closed for the purpose of seizing the edge of a sheet.

s, Figs. 1 and 9, is a rod, which extends across from side to side of the frisket-carriage, and is so atiixed to said carriage as to turn in bearings in its side rails.

The nippers are composed of thin plates q* of steel or other suitable material, jointed together, so as to open and close on said rod 'i in a manner similar to that in which the leaves for a common door-hinge are jointed together, and turn on the pin which secures them together. The upper half or part, q, of each pair of nippers is secured by means of set-screws or otherwise to the rod 8*, while the lower half or part thereof is allowed to turn freely on said rod.- The'said lower parts, r', are drawn up toward the upper ones by means of wire springs t3 t", which are wound around therod s", one end of' each of said springs being attached by means of thecollars and set-screws, as seen at us u, to said rod.

The other end of each of said springs is attached toons of the said lower halves or parts of the nippers.

As a means by which the lower halves of the nippers may be kept in a horizontal posi tion, while their upper halves are elevated, and by which the time of closing said nippers together may be controlled, there is a projection, u', which proceeds from the lower part of the hinge part ot' cach lower half or part,

' r. These projections, while the lower blades of the nippers occupy horizontal positions, re-

main under the projecting hook of acatchbar, v', (a transverse section of which is seen in Fig. 1,) which extends entirely across the frisket-carriage, and is. sustained therein by pivots, which project from its endsvat theaugular part w, andl rest and move in bearings in the side rails 'of said carriage in such manner as toallow the projecting hook to be pressed back by the projections u, which act on its inclined top when the nippers are brought down into a horizontal position. As soonas the same takes place the said catch-bar will be immediately moved forward by the action of gravity to its place over the projections u u', as shown in Fig. 1. The lower halves or parts of the nippers will be thus held in a horizontal position .until the proper moment for them to be raised upward. At such time the hook of said catch-bar is drawn away from the projections uu, and this permits the springs t t to forc'e up the lower blades, r r', and close them upon or against the upper ones. The upper blades of the nippers should be madeso much longer than the lower ones as to allow of their lapping about an eighth of an inch onto the lower edge or banof the tympan, the lower bla-de being short enough to allow it to be brought up against the upper blade without touching said tympan. It is necessary thatNv the horizontal motion of the nippers toward the tympan or feed-board should `be stopped a little' before the frisket-carriage has arrived at its extreme limit of motion toward the right-hand end of the machine or away from the platen in order that the said ni ppers may seize the sheets when they (the nippers) have no other motion than that ol the closing of the two halves or blades toward each other and the sheet between them; otherwise the sheets might be so jarred or moved from their places after having been pointed as to spoil the register. In order to effect this object, the journals of the rod s" are made to enter grooves made horizontally in the edges of the perpendicular parts ofthe side rails of the i'risket?. carriage. To keep the rd s pressed firmly against the inner end of said grooves. and at the same permit it to slide longitudinally in the grooves, small pistons or slides x a", Figs. 1 and 9, are respectively inserted inthe ends of' the hollow cylinders y yl, in which are helical springs' to press said pistons out in such manner as to cause them to enter said grooves and to press firmly against the journals of said rod a.

For the convenience of taking the rod s'out of its place in order to change the nippers or for any other purpose, one end of each ofthe 'cylinders y y is jointed to a projection from the corners of the frisket-carriage and insuch manner as to allow (after the pistons z xhave been drawn out of the grooves or bearings ot the rod s, the same being effected by the pressmau applying his hands to small studs a" a") the other ends of said cylinders to be raised up sufficiently to permit said rod to be removed. The nippers are actuated in Y ner frame, l, Fig. 16.

l the nippers vare attached.

Rylle. 7

the ends of said-stock, and so as to enable a person to disengage it from the frislcet-ear-V ringe and remove it therefrom. 0n the inner Vside of each of the end pieces ofthe main stock, Fig. 15, of said frame are grooves made and covered with thin pieces of steel i* i". calci lated to receive the end pieces, kk, of an Fig. 18 is a view ofonc end of this inner frame, and Fig. 1.7 is a view of the other cud. Then said inner frame. l, is in its place, the end pieces, kkflie in the aforesaid grcovesiu .the inner sides of the end pieces of the said stock, where they can be moved ut about half an inch, but are pre` vented from slipping any furtherout than may be proper by means ofthe two little screws m m, Fig. 14, put into holes, which may be secu at n n, Figs. 17 and 18, the heads of said screws being made to come against the ends of the plates .1" when said inner frame is pressed out to the place it generally occupi by means'of the dat steel spring o, dispos as seen in Fig. 14.

Each nipper is composed of an upper' half, p, (which is made ofa thin plate ofsteel bent nearly into a right angle, as seenin Fig. 1l.) and a lower' half, which has a hinge-joint at r, the part below said joint being riveted or otherwise secured to that part ot' the upper half which -is below the angle thereof. This said lower part of said`upper half is that by which the nipper is secured (by means ofthe screw a, Fig. 11) to the middle bar of the said inner frame, l. (See Fig. 11.) t t, &c.,-Figs. 14 and 16, are screw-holes in said bar, in which the screws which secure the nippers to it are inserted. y

u, Figs. fixed upon 21 and 11. is a fiat bar which is the outer face of the bar to which to close the nippers, is perf rmed as follows: Screws, such as are' denote by Fig. 22, and having friction-rollers, as seen in Flg. 23, are put through peculiar diagonal-shaped slots v e* o', &e., of said bar, and are screwed iulo corresponding holes iu the middle bar of the fraaie ll in such manner as to allow the bar u to be slipped back and forth endwise, in order to cause said friction-rollers and screws lo work freely through t-he whole lengths of the the slots. Now the end w* of the bar u is fitted-to the inside of the forward end of the right-hand end piece of the stock n the manner of a. ruiter-that is to say, both are made angular or beveled, as seen in lil' gs. 14 and 15 so that when the'inner frame is pressed in toward the main body of the stock the beveled end of the said end piece of said stock operates against the end ofthe sliding bar in the manucr of a cani or wedge, and causes it to slip along on the middle barof the frame l, where,A by the friction-rollers, Fig. 23, and screws, Fig. 22, are caused to operate through the said diagonal slots v v, Src. The upper sides of sai slots move over and upon 'said frictionrollers and screws in the manner of inclined planes, aud'so as to cause said bar u to rise Aou the sidcot the frame.

Its duty, which is up and bear or crowd Aits upper edge against the lower blades ofthe nippers, and so as to force or turn said lower blades upward against the upper ones, and cause both of said .blades to take firm liold of the paper. which is laid upon and to he drawn ofi' the tympan or feedboard.

The manner in which these nippers perform their oice is as follows: Let it be supposed that a sheet has heenipropcrly pointed on the feed-board, and the nippers are being moved toward it.h Just as said nippers emerge from under theplatcn the frictiou-roller f on the nipper-frame will enter the crooked groove b This groove or slot. operating ou the said friction roller, will cause the clipper-frame to rise up and elevate the nippers as .they advance until the forward Y ends of their upper blades shall be presented above the edge of the paper on the tympan, f

when by a sudden bend 'or turn downwardin said groove, or by the operation of a cam or other mechanical equivalent, as before mentioned, the ends of said upper part or parts ofthe nippers will hehroughtsuddenly down upornthe lower edge of the tympan and the sheet which may have been laid ou it. At the instant this occurs projections v, Figs. 11, 16,

17, and 18, from the corners of theinner frame meet projections c d', Figs. 2 and 3` from the sides of the fraaie, which arrest the further progress of that part ofthe nipper-frame and the'nippers; but the frisket-carriage and consequently the main stock ofthe nipper-frame continuing to move on for a short space further, the said inner frame, l, Fig. 16, is pressed vin toward the main part el' the stock Silicientl y to cause the beveled end w of the end piece, z', of said stock to operate on the sliding bar u' and 'cause it to close the nippers upon the sheet, as above described.

The movement of the frisket-carriage in the opposite direction carries the sheet in between the bed and platen. the same as in the case of the nippers first described. The bar u is thrown back so as to relieve the pressure ot' nippers upon the paper, as follows:

3f, Fig. 2, denotes a wedge or cam affixed by one end by means ofa screw, pin, orpivot, z, to the side of the frame ofthe machine in the manner oi' a latch or click, its place on the side of the frame being such that very soon after the nipper-fraiue shall begin its mo tion toward the right-haud end of the ma.- chine the end y-'lot' the bar u* will be brought against the wedging part u, which will cause said bar to slide'back endwise, its diagonal slots at the same time allowing it to drop down, and thus to relieve the lower blades 'ot' the nippers, so that said nippers shall open to receive the sheet as the nipper-frame shall be elevated, as before described. When the nipper-frame, with the nippers closed, shall be iu motion toward the left-hand end of the machine the end gf of said bar u will be brought in contact with tlie under side of the wedge y, and will elevate it so as to pass under it.

As soon as the bar passes beyond the wedgeclick, the latter willd rop back to its place of 115i, Where it will be rendy at the proper momegt again to operate on the bar u,` as aforesai placed is represented at b.' Fig. 1, the said form beingr also exhibited at `The bed is constructed iu the usual manner, and must be strong cndugh to sustain the linprcssion. 'hile it rises or falls it is kept steady in its place by menus ol' projections from its ends,wl1ich slide in grooves d, Figs. 2 and 3; formed on the side pieces of the frame, and also by a guide-piece, e, Fig. 1, firmly secured to said bed, :ind made to project into other vertical grooves formed on the sides of the frame at f, Figs. 2 and The bracingrods g, Fig. 1, also serve to preserve the horizontal position of the bed.

The platen is represented atJ, Fig. 1. Fig.

to be hereinafter-described.

1' denotes the bottoni bar which sustainsthc im ression. It extends across the machine,

an is connected by its ends to the platen by strong ironbolts, which pass up by the sides 0f the press-frame from the said ends, and are received in the openings k ki, Fig. 24, prepared for the purpose in the side and nearthe ends of the strong rib-piece l5, which passes orgel' the top of the platen and forms a part o it'. 1

mf n, Fig. 1, are progressive levers, called togglejoints by which the bed is successively raised np, sons to bring the types in contact with the sheets against the face of the platen with suitable force to produce the impressions. The lower end of the lower one, n, rests on a ledge, o, projecting from the side of the bottom bar at its lower edge. The npper end or' the upper one, mi, is made to operate against the under side ol' the bed, as seen ntp, Fig. 1.

The toggle joints are operated by means cf the alternator q, which is in principle of construction and operation very similar to that described for operating the frisket-earriage.

r is a. frietion-rollc`r, against which the altern'ator acts to throw up and straighten the toggledevers. Said roller is placed on the center joint-pin, s, and in a slot, t, about four inches wide (the length ot' the roller) in the middle of the toggies, said slot being made to extend from u in the upper lever to na in the lower one, and forms s suitable opening for the alternator q" to play throngh.'

z v denotes a pitman, connected at one end by means of the pin cri with the said alternator q, and at the other end (by means ot' n strap, key, and boxes) to the crank-pin fi, Fig. 7, which projects from the side of the rot-ating toothed wheel. The left-hand end of the pit-- man is forked, so as to receive thenpper part of the alternator q between its two flat prongs. The pin is put through the said prongs and through the crooked slot y in said alternator.

The bed on which the form oi' types is' .impressions are produced.

which slot has an abrupt deprcssionat one end of it, which forms a suitable bearing for tho said pin a".

The operation ot' the alternator in straighteni ng the toggle-joints, elevating the bed, prod ucing the impressions, and lowering the bed down again is as follows: Let'it be supposed vthat the machine is in motion, and that the erankf, Fig. 7, 4by means of the p'itumn, hasthrown the alternator forward 'toward the toggles until the part indicated by the dotted' line z, Fig. 1, hnsarrived as far as tho center of the friction-roller 1". The side of the month of said alternator toward the crank will now form a curved inclined piane on one side of themain part of thc said alternator, which, continuing to advance, will now act against the4 roller r, so as to press it forward, somewhat in the manncnof a lever lof the second class` (as being the fnlcrum,) and will cause said roller toroll 'up the said curved inclined plane until the toggle-joints are brought nearly into line with each other, and theimpresson is produced. The instant the impression will have been thus produced the crank f will have passed its line 'of centers and will begin to draw back the alternator, which, by a reverse action a ainst the friction-roller 1*, will bring the togg e-joints and the bed-in roper time to their places of rest, as seen in ig. 1. That .part of this alternator from-bs to c* is formed as an are of a circle whose center is in the fulcrurn a' of the alternator. Its oieefis to keep the toggles and bed down steadyn their places during the time when 'the types are being inked by the inking-rollers.

d is a slide, which is embedded in a groove, e', made in the side of the alternator q in such manneras to allow' of it being slipped up against the pin a", so. as to raise said pin ont of the depression of the slot in the nppe' part of the alternator, in order that when the pitman is thrown forward said pin shall slip through the remaming or curved part of the slot, and thereby in order to prevent an im pression being produced allow the alternator to stop short of the place it is earriedto when This slide is op erated by means of two arms or levers, f g', axed to the two ends of a rocker-shaft, It, (see dotted lines in Fig. 6,) one end of which has a bearing in the b`ox 1, Fig. 6, and the other end a bearing in the hole Jr, Fig. 3, made i'n the side ofthe fram'e. The armf at one end of said shaft has a friction-roller, l, aixed near to its outer end. Said shaft is so placed as to bring said-friction-roller under the curved part m' of said slide. The arm g' on the'other end of,said shaft should beinade of the necessary length and shape to bring its outer end into close proximity with thc foot of the person who may be employed to lay the sheets on the tympan. When it may be necessary to prevent un impression, such person may with thc foot upor. the outer end of said arm depress it so as raise the said friction-roller against the said curved part of connected, by the arms projecting from 4Q( lie s said slide, and thereby elevate the said slide jointed to the platen at b". The said springs and the pitmnn, so as to cause -said pin x to are for the purpose of causing the rollers to pas; into the upper part of the slot, as aforesai to allow ofthe rollers conforming to any dii`- ference of length which there may be in the two edges of the said sheet.

The ends ofthe sheet are joint of the toggles and the face of the bed l secured to said rollers by puttingeaeh of them into a groove, c and e', Fig. 1, (made alon in the side of each of the said rollers,) an' afterward pressing a rod into each of the said grooves, so as to wedge and confine the said sheet to the rollers.

ffy y* y', Rigs. 1 and 24, are wheels, which sustain the platen upon the horizontal railways formed of the 'upper edges of the two side pieces, Figs. 2 and 3, of the frame. These wheels, which sustain the platen, are fixed to the ends of shafts zfz, which have journals stands on and'above the platen, and nay be that.run in bearings at a' .z a' a', Fig. 24. unshipped at will by the operator, and is in- The office ofsaid shafts and wheelsistoserve tended to receive the heap of paper from tween the parchment and platen parchment tyi'tpan' is secured to the face of and laid upona table, as follows:

The terial in such manner as to leave suitable lianketing is put within this tympan and`be- The tympanfsheet d', Fig. 25, consists of a sheet which may lie upon said frisket. This long sheet of paper ur other suitable matefrisket rests on the top of the frisket-carriage, rial, which is to be relied up on a' roller, ci, Figs'. 24 and 25.4 whicl. roller is suspended by its'jou'rnals iu rings attached to one side ofthe platen. From this roller the endof the sheet is taken and passed under the platen,

from the carriage. successively after each of the impressions have been produced on the sheets of paper they frsket holds the said sheets up while the types are allowed to sink said roller e being suspei ded by its journals l down, and thus said frisket (together with the in bearings, which rest on springs a and arel nippers,which at the time hold onto the sheet) i In Fig. 1, denotes movable table, which.

lo RX no scrvesto overcome the adhesion of the ink, and to separate the sheets from the type, this being the beginning of thc process ot' removing the sheets from the press. After each of the sheets of paper has thus been separated from the type, the frisket-carriage begins its motion toward the right-hand end of the 'niachine, and each sheet is carried out in a horizontal position on said frisket from between the type and platennntil it has advanced to a certain position. lVhen this takes place. the forward edge thereof will be elevated by means of bellows,or some equivalent de vice, in sugli manner as to allow of its being taken hold ot by a system of rollers andV bands. Rollers or pulleys alo'ne maybe made to answer the purpose, whose office is to withdraw successively the printed sheets from the frisket and present them to the act-ion of an Ainstrument. which I call a tiy, which being accomplished the said instrument removes the said sheets from said system of rollers and bands and throws them on the pile or table, or other convenience provided for thepurpose, as follows:

Fig. 7 is a detail view of most parts of t-he "taking-oapparatns as seen in their relative places, the spectator being supposed to be standing at and looking toward the righthand end ot the machine. k", Figs. 1 and 7, denotes a bellows, which issustained in its place by proper means. Said bellows has` two long slits, l P, or any proper number of holes made through its top boord, thesame being to allow of the escape of air upward when said bellows is closed, and for the admission of air when it is opened. This bellows is operated as follows: mi, Figs. 1 and 7, denotes atransverseroeker-sha1t sustained by its gu-.lgeons in proper bearings on the sides of the Trame. This rocker-shalt is provided with two arms, n nl, which extend underneaththe bellows for the purpose ot' operating it. Said shaftis also provided with anotherarm, o, which extends in an opposite-direction Ato that of .the arms u' n', and has a friction-roller, p, axed on a screw pin or pivot near to its end. Said roller is for the cam q, whiclris afxedto the shaft s', to operate against.

r" is another arm, which also extends from the'rockershait m' and has a weight, si, suspended from its outer end. The proper shape of the cam q is indicated in Fig. 1. The cani qi being in the position represented in the drawings, the friction-roller p should bear upon said cam at t", in which case the bellows would be closed; but in orderto show the bellows open in the drawings I have drawn the said friction-roller and the arm to which itis attached, as well as the other arms of the rocker-shalt nf, in the positions they are carried into when the bellows is opened. Now,

letit be understood that the machine is in operation, and the friction-roller p bearing on the cani qi, as aforesaid. In such case the cam will operate ou said friction-roller, and

will communicate motion t it und the arm o', and by means of said arm o' and the rocker-shaft m' motion will also be commuto bring said arms severally into the positions in which they are represented in the drawings. The bot-tom board. t', of the bellows will follow by its own gravity and descend with the arms u n until said bellows is fully open. Ab'out this time t-he most prominent part of the cam q will pass 'in contact with the said friction-roller pl and leave said roller free to descend. This bei ng effected, the weight sT will draw-downtlie arm a", and by means of the said rocker-shaft mt and the arms n7 n will will force up the bottoni board, t', and close the through the slits or holes through the top thereof. The aix-in passing up through holes made through the frisketwill impinge against the sheet and elevate it suieiently to allow of its being taken. hold ot' bythe delivering. rollers, as above naniedf. By turning the cam q around on its shaft s', either one way or the other, and to such extent as the ease may require, and afterward lsecuring the same by means of a set-screw to the shaft, the period ot' blowing the bellows may be regulated so as to cause the current or currents of air from it to strike against the sheet of paper at the propertime and place. The said delivering rollers may be constructed and be made to operate as follows:

u' n, Figs. 1, 7, and 26, (the lutter figure bei ing an end view of the system'ot' rollers now to lbe deseribed,) denote two rollers extending from side to side of the machine. The said rollers have .a series of endless bands or tapes (one of which is seen at w', Figs. 1 and 2) running over them in the grooves .r'x' x',- cc., Fig. 7.

y' z', Figs. 1 and 4, denote two other similar rollers, which have anotherand corresponding seriesof endless bands,a',runningaroundthem, and certain grooved pulleys, bl b', Sze., Figs. 1 and 7, which pulleys are placed on the transverse shaft c. The number of bauds may be more or less, according to the size .of the sheets the machine may be intended to print. The rollers u lfand their bands may be regarded as one set, and the rollers yl z,with their bands, may be regarded as another setot' said rollers and bands. The said sets of rollers are arranged in and sustained by a. frame, dl, as seen in Figs. 1, and 26.. The said frame is supported by two of its corners on the bop rails of the press-frame. Its other two corners are supported by pivots e' c in bearings which 'admit of the frame and its rollers being raised up into a vertical position, as see'n in Figs.' 7 and 26in order to make room to remove the platen from its position directly over the types. 4

j", Fig. 7, denotes au endless band which runs around a pulley, g", on the shaft c, and the roller t, the same being to assist in drivf nicated to the other arms, n u' and r, so ns bellows, and thereby expel the air swiftly ing the rollers u v y z. The pivots of the R ne u shalt d ru'n in him-ings IN1", affixed tothe lop edges of the side-pieces ol' the frame of the machine, as seen in Figs. 2 and 3. These bearings should be nmdc adjustable. The said delivering pulleys, rollers, and hands nre driven or putin motion by means of an endless band, i', which runs over the pulley k on the fly-wheel shaft, and the pulley l on the shaft L. By means of a propcr'proportion between the diameters of the pulleys k" l any desirable speed may he given to the delivering rollers and bands, so as to quickly present the sheets .to the action of thev ily, to be hereinafter described, without interfering with the action of any other part of, the machine.

The operation of the delivering rollers and pulleys and bands is as follows: Snpposing the machine to'be in action, and lhe l'risket to be carrying a sheet ont fromv between the bed and platen, and that Vsuch sheet has arrived at the proper place for it to he elevated by the bellows, as before described, the moment said sheet is so elevated the forward movement of the frisket will cause the sheet to enter between the aforesaid -two sets 0f rollers and bands, which rollers and hands, as wellas lthe pulle 's on the shalt c", being in motion,will quickly dihw said sheet from the irisket and present it to the action ofthe ily m", Figs. 1 and 27, whose construction and operation is as follows: Fig. 27 denotes a top' view of said il y m, including the roekershaft n, to which said ily is attached, the spring o" on said rocker-shatt, by which the fly is suceessively thrown-over to lay the sheets on the pile, and the toothed wheel or pinion p, by means of which the fly is brought back to the proper position for receiving the sheetsfrom th delivering-rollers. Said fly is composed of the arm or stock q', Figs. 1 and 27, and a series of lingers or prongs, 1' 1, die., which project from said stock, asseen in Figs. 1 and 27. Every succeeding pair ofsaid fingers except the two outer should be ccvered with light cloth or other suitable material, as seen in Fig. 2T, so as to form a species ot' web from one finger to the other. The object of this is to enable the air to act against said webs whenV the ily is putin motion, and modify or retard the velocity which it would otherwise receive. A friction-spring. a. Fig. 27, is made to cooperate in the same object. This it does when the ily is thrown over by sliding along against 'a sort of curved and stationary cani or inclined plane, t', attached to the frame of the press, as shown by the dotted lines in Fig. 7. XVhen the liy is in its proper position for receiving the sheets, as shown in Fig. l and hy the dotted lines in Fig. 7, the several endless bands of the lower set of rolleis and pulleys enter the spaces u u, 'c., between the lingers. The rocker-shaft u", to which the ily is attached, is sustained in bearings on the top of the front side 0f the machine. The winding, or, as it is sometimes called, spiral spring o on the rocker-shaft n is secured to said .shaft by means of the collar 1r und the setscrew v. liy means of said collar and setscrew the former may hc turned around and secured in any place which muy be necessary to adjust or temper the force of the spring lo thc labor it may have to perform in successively throwing over the ily in order lo lay the sheets on the pile. The other end ofsaid springl o" is secured to lhc pressi'rame by inserting itin a hole made inthe side ofthe collar z, Iwhich collar is held fast by means of the pin y, which projects from it, and is inde to enter a hole made in the side of the bearing for the journal of the said rockershaft. The iy sl.ould be capable of swinging through an -arc of one hundred and eighty degrees, more or less, as circumstances may re q uire. The rotating cam z", Figs. l and 7, operates the vertical lever a', which in its turn moves the horizontal slide and rack b. Said slide-rack gears into and turns the pinion p', and consequently the rocker-shalt and liy, to which said pinion is attached, the same being done in such manner as to carry said ily over and into 'the position it must occupy in order-to receive a printed sheet of paper from the delivering rollers and pulleys hereinbcfore described.

d', Fig. 7, denotes a connecting-rod, which by properjoints connects the top end of the levera' to the slide-rack b. The fulcrum of said lever is seen at d', Fig. 7. Said fulcrum may be aixed to a bracket, which may be bolted to any convenient part of the end piece of the press-frame. It is best that this fulcrum be made capable of proper adjust-ment. On the lower end of the levera a friction-roller, e', is placed, it being for the cam z to operate against. The part of the cam which gives motion to the lever is seen at f The part g is used to hold the ily still the proper length of time for Ihe reception of the sheets from the delivering-rollers. The. part h is quick turn or falling o' in said cam calculated to leave the lever a free from the action of -fthe said'canl at the instant and during the time necessary for the action of the spring o' when it throws the tly'upward and over upon the pile of sheets. The. said ily-cam should be made adjustable by being so fitted ou the hub ofthe cam q as to be easilyturned round upon it, either o nc way or the other, as the case may require. It may be secured in place by a screw. I n case the tly-frame shall be hung upon the front side of thepress, as above described, thc table for the reception of the pile of printed sheets as they may be delivered from the machine by the said ily must be placed at the right hand and nearby the person who may point the sheets on tympan.

The operation of the'y is as follows: Supposing the machine to be in action, and the ily to be in the required position for the reception of a sheet from the delivering-rollers, and said sheet to be on its way through the said delivering-rollers, and that it is being carried ou the bands over the Iingers of the ily, the moment its forward edge reaches the upper n. R ne edge of the stock or arm of said fly, or when said sheet shall be properly presented by said delivering rollers and bands to the action of said fly, the prominent part g Vof the cam will have passed clear 'of the friction-roller c. This will leave the lever a free to move back or its friction-roller. c free to move down the part h of said cam., The spring 0" will then immediately throw the dy, with the sheet upon it, over npn the table or heap where'on said sheet will be deposited. After the sheet shall have been th'ns delivered on the heap, the action of the am on the friction-roller e. will cause the ily to move back in proper season and to the required position to receive the next sheet from the said delivering-rollers as it may pass through them, as hereinbefore described. In moderate-sized printing-machines it is best that the sheets should be laid ofi' at the front side of the machine, as above described; but in the case of very large ma.- chines it may be desirable to deliver the sh'eets at the right-hand end of the machine. In suchease the fly and the machinery to operate it may be modified as follows, to-wit:

Fig. 2S is a top view of the ily, the rockershat't n", to which it is attached, they toothed wheel p, 'and the spring o, which operates said fly. t" t" are the gudgeons on which said rocker-shaft turns. JJ k", Figs.` 29 and 30, denote bearings for said gudgeons, affixed to the two sides of the press-frame. m', Fig. 29,

shows the position this ily occupies when reeeiving a sheet. The dotted lines m, Fig. 30, L denote the position of the said ily when de livering a sheet on the pile or table. Fig. '31 is an elevationl of the cani z, the lever a', the rack b', and the toothed wheelp, by means of which the said ily is operated, all of the parts of this figure severally occupying their proper plaees'relatively to each-other.

q?, Fig. 30, denotes a ,table to receive the pile of sheets as they may be delivered from the machine. r is a rocker-shaft, to which said table is attached by means of one or more arms, s t, jointed to a vertical bar, nl". The lower one of said arms is jointed tothe pressframe.- B y means of said arms and verticalbaru.9 the table may be elevated or depressed, as occasion may require. 4

-Having' thus described my machine in a detached manner, 1 will now explain the conjoined operations of the several parts when in combination with-,each other and for the performance of -the usnalprocess of printing. The machine being supposed .to be in order for printing, and the fountain propof giving the impressions.

erly supplied with ink, the first thing to be done is to turn bot-h the tympan and the rollerframe into nearly vertical positions, in which` they maybe secure'd by means'ofsnitable contrivances provided for the purpose. The platen is next to be moved away from over the bed. Next the frisket and the nipperframe are to he removed, so t-ii'at the form. of types may be conveniently put and secured iu its place upon the bed in the usual way. When' the frisket lias'been properly covered audfitted to t-he form, as before de- .Scribed, it andthe nipper-frame may. be put in their places, care being taken that a set of nippers of the proper length for the width of sheet to'be printed be adapted to the said frame. The platen may next be moved r back to its place over the form of types, and the tympan and roller-frame may be turned down to their proper positions. The points must next be attended to and adj usted to theirproper places for producing register,by means -of-the apparatus for the purpose beforedescribed. This is liest done by experiment, as is usual in other printing-presses. Afterthese things have been properly attended to, let.the paper,snitably prepared to be printed, be laid upon the table providedto receive it. The person whose duty it is 'to point 'the sheets having placed pue foot upon the lever to prevent impressions' from being produced, the machine may be started or putin motion. If the inking-rollers are free from ink when the machinel isathns pnt in action, it will be' neoessary toY run thejmachine awhile wit-hontpro dneing any impression.' or until the' rollers are properly covered with ink. A sheet may next 'be pointed, and -directly afterward the foot must be removed from the lever, in order that the machine may commence its operation All Vparts of the machine being now in operation together, in the manner before described of the several.V parts separately, yand the inking-rollershaving rolled over thefori of types and covered the faces with ink, the nippel-s will next ad-l vance and seize the sheet of .paper on the tympan or feed-board, as before described. The

.frisket-carriage will next be moved (by its alternator, as before described) toward'the leit. hand end of the machine. This will carry the cam i against t-he stud k and press back the' spring h ,.and thereby disengage the arm of the lever e, which will cause the points to be disengaged from the sheet., The nippers will then immediately be made to draw said sheet from theA tympan. Said sheet, as it slides from said tympan and as the frisket is carried along under it, drops down npon the frislcet, as hereiribefore described. 'lh'ns the sheet will be introduced vbetween the platen and the form of types, and 'when the motion of the frisket-carriage is arrested the sheet will have been brought into a proper position to receive an impression, Alittle before thshappens, the bed (by mans of the alternator, as nforcsaid) will begin to rise, and immediately after said sheet has becom'e stationary will be forced up by the continued action of said alternator Ry no l 1.7

and other parts ofthe mechanism until the form of types is carried in Contact with the said sheet and against the platen with suicient force to produce animpression. The said alternator will then be drawn back by the crankf',which will canse the bed to descend to the position in which it rests while the types are being inked. The friskct-carriage will next again move to- Ward the right and again carry the inkingrollers over the form and the nip'pers toward the tympan, and the frisket, having the sheet upon it, out from between the bed and platen and under the feed-board until the right-hand edge of said sheet arrives over the slits or holes in the top board of the bellows. This being done. the cam g" will allow the bellows to be operated as aforesaid and ycause one or more swiftcurrents of air to impingef through-the 'frisket against the sheet ot` paper and elevate the edge of saidl sheet, which, continuing to advance by the movement of the frisket, will be quickly seized by the delivering-rollers and carried over t-he ily, which at the proper mo` ment will b thrown over so as to deliver said sheet on the pile, as above described. In the meantime another sheet will have been pointed and taken by the nippers into the press. said nippers being made to grasp the said sheet about the' time that the sheet previously print ed enters between the delivering-rollers. The delivering apparatus is thus made to deliver one sheet while anotheris being carried into the press and printed. The.tympansheet is most needed when the second side of the sheet of' paper is printed; but it should also be used when printing the first-side thereof.

All parts of the above-dcscribed machine are capable of modification, and equivalents Well known to mechanics may be substituted for almost any one or more of them; but as I am persuaded that such modifications or snbst tutions as may under any circumstances be of any advantage will be readily made by mechanics skilled in the business of press-makj ing, I refrain from further explanation of the same.

Having thus'speciled my improvements, I shall now proceed to point out the nature and extent of my claims.

The mechanical combination by which the motion produced by the crank and pitman is so modified and communicated to t11e` togglejoints as to produce the impressions, and so as to give to said togglejoints the necessary intervals of rest and reciprocating motion, the same consisting of the alternator q anda connecting-rod or pitmah, w", in combination with said crank f, Fig. 7, and said togglejoints, or any other mechanical equivalents, acting substantially as specified, the said toggles having a roller, r, or any mechanical substitute therefor. V

2. The mechanical combination employed 'to operate the frisket-carriage or impart to it with the inking-rollers and nippers their peculiar intervals of rest and reciprocating m0- tionstoward and from the form of types, as described, the same consisting, first, of the alternator g; second, the lever or arm orarms o' w', their rocking shaft 'z', and roller i, connectedwith the alternator and frisket-carri age; third, the rocking shaft-c, arm d', connectingrod e, and the crank h, or any mechanical equivalent or'eqnivalents therefor, the whole being made, arranged, and operated together substantially in the manner as hereinbefore specified.

3. In combination with the alternator qcnd pitman w, the slide d', operated by the treadlein the manner substantially as described, whereby the pressman at any time while thesaid alternator is in mot-ion is enabled to prevent it from being thrown or moved against the 'tog gles (or roll thereof) suiciently to straighten o'rmove the said toggles into line with each other, and thereby produce an impression -from the form of types.

V 4. The combination of mechanism (or an equivalent or equivalents) by which the nippers (seen ln Fig. 1) are operated, the same consisting of the rod s' and its arm at, the springs t, the catches u and v, and the grooves 'b, and the sto s c* d, and theA rotating earn named in the escription. y

5,. The combination of the said nippers lwith frisket-carriage, operated as above set forth, the same being for the purposes and constructed substantially as aforesaid.

. 6. The mechanical combination (or an equivalent.' or equivalents) constituting the means forl making or obtaining register, the same consisting ofthe movablestocks x, the points n2, and thelevers v', w', and and mechanismv consisting of the cams z" and g and the spring h', which operate them. the same vbeing applied and constructed and operating 'substantially as hereinbefore described.

7. The manner above described of changing the position ofthe register-pointsso as to range with each other across the feed-board and the -sheet'eitlrer inonedirection or the other, in

order to enable the pressman to turn the sheet and print its second side'iu another direction, all as set forth.-

8. The method above described of securing greater certainty of accurate register-that is to say, causing the nippcrs to rest from their horizontal` motion (or from that motion by which they are carried toward the sheets of paper) while they are being closed on the said sheets of paper, and while the carriage or part from which they receive said motion continues its movement, substantially in the manner set -fort-h.

9. The above-described manner of constructing the nippcrs-that is to'say, the making the upper blades somewhat longer than the lower blades thereof, wherebythe said upper blades are made to project beyond the said lower blades, in o rder that they, the said upper blades, may be pressed down upon the edge of the sheet of paper on the tympan or feed-board, so as to hold the paper 'still theremake it correspond u i K1 pers, `the same being of importance for the se-A curity of good register.

10. For the additional-security of good register, withdrawing theregiste'rpoints from the paper atte;` it hasbeen seized by the nippers, but previously to its being started from the place in which it has been Vadj usted orpo nted,

-the same being necessary to-secure good registcr and prevent any enlargement ofthe pointholes or. tearing of thepa per at the point-holes n iade through it; v

11. Altering the width ofthe tympan t o with isheets of various widths or nippers of various lengt-h, while the register-points inthe meantime are 'still preserved in their central position.

12. The deliveringbands iv and a"and also the delivering-rollersu, nl, y', and z,operating substantiallyas aforesad,or mechanical equivalents for either or all of them, in combination with the frisket or any equivalent therefor, the snme'being for the purpose of receiving a sheet of paper from said t'risket and deliY.- ering it upon a ily-frame or any other contrivance destined to receive it. l 13.. The combination ofa bellows or other` equivalent with the frisket or snpportof the sheet of paper, and the t'wo series of receiving and delivering endless bands or tapes, the same being arranged and made to operate substantially in 'manneras specified.

,- 14. V'lhe delivering ily-frame or its equivalent, in combination with the deliveringbands wT and a", and also with the deliveringrollers' u", r", yi, and "zi, and also with the shaft g* and the pulleys b' bI bb, dsc., operating substantially.as aforesaid, or any equivalent or equivalents for either or all of them.

15. The employment of the fly or its equivaient' for receiving and piling the sheets.

16. T he arranging and operating the fly-V.

frame in` such mannerthat its motions may he,1n directions perpendicular, or thereabon't.

to the side of the press, the same enabling ine,

'te' deposit the limprinted paperin a heap close toV or directly by thc side of the pressrnan,

and thus afford him the opportunity of more' readily examining each sheet after itis'printed than he would crate-din any other direction.

17. The manner set: forth of operating the nippeis, vand which is also exhibited in Figs. 11, 14, 15, 16, 17, 18, 19, 20, 21, 22, and 23, and liereubefore described:

1S. The combination constituting the mech enjoy if the ily-frame opanism employed to conv'y the printed sheets fromthe delivering rollers and bands (or an equivalent) to the pile or table provided to receive them, the same consisting, rst, of the' delivering ily/#frame or a substitute operating subst-antially'the same; second, the mechanism (or a substitute therefor oper- 'ating'.substantially the same) employed to givesaid'ily its proper motions and intervals of rest, the sameconsisting of the cani e, the lever a",. theraclr b", the piniony pf, and the spring o; and, third, the devices (or substitutes operating Asubstantially the saine) employedfor the adjustment and government of the motions of said y,'and its -intervals of rest with respect to extent andtime, thesaine being done by making the. cam z, the spring o,and the fulcrnm ot the lever'a'. adjustable. Y

19. The manner of constructing and errang ing the delivering iiy-frarneby which it may 'be depressed below the' bands, rollers, and

pulleys, by means of which the sheets of pa per are successively presented to the aetionof the said ily in such 'manner that said ily shalln'ot itself obstruct its reception of the said sheets preparatory to delivering them von the ile. .P 20. Thedetached or independent manner of arranging the delivering-bands, pulleys, and rollersby r-hich I am enabledto give any required velocity to them or any of them, and in that way'toj govern the time of the final delivery of the sheets successively with reference to the timesof action of other parts of the machine,"aud thus to gain a saving lot' time which could not be gained were the ve.` 4locities of said bands, rollers, and pulleys ar' bitrarily governed by the motion of the frisket or frisket-carriage,or any other part of aflat-` surl'aee, press, or bythe velocity of the cylinder or any other part of acylinderpress, the same being done by altering the relative di ameters of the pulleys'kand l', or any equiv? alentmethod.

21. The constructing one or .more of the distribution-cylinders so as to make it capable of receiving and containing steam orhot' or cold water, by which its temperature, las vwell as that oi vthe ink upon it', and which is, to be imparted to the rollers,may be governed.

In witness .whereof I have hereto set my signature.
