PRINTING MECHANISM.

Specmoation of Letters Patent.

To all whom 'it may concern:

Be it known that I, HARRY C. GAMMETER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga. and State of Ohio, have invented a certain new and useful Im rovement in Printin Mechanism, of whic the following is a fu l, clear, and exact description, reference being had to the accompanying drawings.

'This invention relates to rinting maf chines of the type commercie ly known as the multiv aph, wherein there is a rotary printing typ and a suitable platen coperating therew1 The features comprised in the resent invention are the means for pro r locating the type on the drum and lildling them against endwise displacement; the mechamsm for guiding the sheet as it asses`between the drum and platen, and t e mechanism for finally ejecting the paper so arranged that it and the means for holding the type are ad'ustable lengthwise of the drum, so as to allow the assemblage of matr ter of different widths and the e]ection of paper corresponding thereto.

The object of the invention is to present these features in simple and eiicient mechanism. Such mechanism is hereinafter more fully described in connection with the drawings.

Figure 1 is a front elevation of the printing portion of a multigraph embodying this in ve-ntion; Fi 2 is a vertical section through the same; ig. 3 is an enlarged vertical section parallel with Fig. 2, showing the paper feeding mechanism; Fig. 4 ha a vertical section of the parts shown in Fig. 3, lookin from the other direction; Fig. 5 is a vertica cross section in afplane parallel with Fig. 4, showing the paper ejectingrolls; Fig. 6 is a rear elevation of the paper ejecting device; Fig. 7 is a plan taken just above the impression Vplatem andL showing the lower members of the paper fd and the paper ejection mechanism; Fig. 8 is a vertical section through the 'guide for the ed of the paper,l being taken on the section ine 8-8 of Fig. 7; Figs. Stand 10 are sections showing the lock for'the adjustable cam which controls 4the paper feed, these views being taken on the correspondingly numbered rum adapted to carry individual lines of Fi 1 Fig. 11 is a erspective view of the bloc forming a portildn of such lock; Fig. 12 is a detail showing a cross section of Patented oet. 24,- 19,11.'

a portion of the drum together with the fasl tening devices of the type hold' band; Fig. 13 is a perspective view of t e t ho din band, the same bein broken out 1ntermediately, and Fi let 1s a perspective of the edge guide for e paper.

In the embodiment shown4 in the drawings, there is a suitable base A from which rises a pair of vertical parallel standards 0r end plates A and A. Journaled in these lates is a main driving shaft B 'on which 1s mountfxl the printing drum B. The surface of this drum as shown in Fig. 12 is provided with undercut ooves b for the reception of type C which have laterally extending feet, whereby they may slide lengthwise of the ooves but are held therein against latera and outward movement.

An suitable means is provided for allowing t e type to be assembled on the drum.

Fig. 1 shows at a a suitably formed guiding channel across the frame member A by which the type may be slid to and from the printing drum. Beneath the printing drum is a. rotar impression platen D connected with the rum by gears b and dillo vthe drum and laten respectively; `The rilm has a considerable opening in its periphery, adjacent to which it carries a air of spools E. lA suitable inking ribbon 1s adapted to be carried by these spools passing around the drum. A crank B2 is-shown as providing means for rotating the drum. When the drum, having type assembled on it and a ribbon passed around the type, is rotated, paper may be drawn between the drum and platen and thereby be printed. l

As the type are freely slidable along the drum, it is necessary to have some means to prevent their displacement, and this means should beso devised that it ma be adjustablv positioned on the drum to low matter of dierent widths to be assembled thereon. This type holdingV meansl must also be of such character that it does not project farther than the type, so that it mayl pass rbetween the drum and platen without impressin or marring the aper. I have found t at the desired resu ts may be very etliciently accomplished by one or more steel .bands F each of which is roviaed at its end vwith hooks These terva1s,say at distances equal to y ands are passed around the m adjacent to the ends of the lines of 'ty thereon and the hooks are hooked over t eed of the drum at the oplening therein, as own in Figs. 1 and 12. T e hooks .f may be ve conveniently made o f wirefbent into a. U ape intermediately and having the ends crossing each other and4 `preferably on the bases of the type grooves,

as indicated by the dotted lines in Fig. 1. By means of the bands the matter on the 'drum' may not ,only be very conveniently locked to the drum, but the bands being accurately positioned by the guiding marks, the pro er and` uniform margin 1s maintained or all the lines. Short lines, as at the ends of paragraphs, may be held at one end by suitablerubber plugs Vset into the grooves, as 1s well understood.

The mechanism which grips the paper and feedsit, includin the feed rollers and stop fingers herein s own, is the subject late through openings in Va,`

'of my Patent No. 846,992 granted March 1'2,

1907.- The mechanism for controlling such feed rollers and timing thereof shown herein is covered in my divisional application No. 396,571, filed Oct. 9, 1907. For completeness, both .mechanisms will Ybe 'described herein. l

As shown in Figs. 2, 3, 4, and 7, g represents a shaft on Vwhich are mounted sleeves G forming an interrupted roller projecting orlzontal rame plate As constituting a table. This roller has a gear g meshing with an idler g2 which meshes with the gear d on the platen. Above the rollers G is a roller H mounted at its ends in pivoted arms, of which the right hand one is shown at H. This arm H is extended inwardly andcarries a roller zl which is adapted to be engaged and depressed by a cam K carried by l the printing drum. Such depression maini as tains the roller H out of engagement with the rollers G, as shown in Fig.v 3.

J represents lingers adapted, to project through. openings in the' table A, these lingers being rlgidly mounted on a rock shaft y'. A spring j surrounding this rock shaft tends to keep the fingers with their u turned ends projecting above the plane ci) the table and into engagement with the miler H 0n the forward end of the arm H is an extension It which has a downwardly extending `lug adapted to bear on Va rook arm i2 on the shaft j. When the parts are in the position shown in Fior. 3 (the cam engagm the roller h) the s eet of paper isshoe by hand across the front portion of the table A3 until its rear edge is. stopped by fingers J.

When the cam clears the roller a spring h2 swings the cam roller upward, bringing the forward end of the arm H' downward.

This movement vthrough the extension h swings the rock shaft j and draws the lingers .J downwardlyout of the way of the paper.

At the same time the roller H descendlng, comes on` the paper and moves it between itself andthe rollers G, t-hese latter rollers being constantly revolving to feed the paper so that it passes between the drum and the f impression platen. The forward ,end of the spring h2 en ages in a series of notches in a stationaryV ar h3, whereby the force of the spring-may be adjusted. The paper feed mechanism is partly hidden from view by the shield and paper guide a2 carried at the vfront of the machine.

When the sheet of paper is placed in position against the ngers J, one edge of the paper at least lies beneath the metal strip N. This strip extends from beneath the roller H rearwardly across the barrel d of the impression platen and adjacentto the softsurface l2 thereof. Beneath the strip N is a strip N' the forward portion of which curves downwardly around the upper part of the platen barrel, the two str1ps extending rearwardly in arallelism from a point adjacent to the hlghest line of the platen. The parallel portions of the two strips are brought together at their outer edges and are carried by'a sheet lmetal bracket N2 which is secured to the tableplate A3. In the preferred form, the two stri s N N and the bracket are a single integra piece of sheet metal bent on ltself as shown in Fig. 14. This luiding structure is supplied at each end of the raised surface to the impression platen. If the paper is of a full width each edge is guided by these strips. If the paper is narrower than the full width, one edge is guided, which has been found suilicient.

It is desirable to maintain the feed rolls out of coperation during a considerable portion of the rotation of the drumso as to allow ample time for placing the sheet against the stop fingers; and it is also de-V spondiii to the length of the cam. The 'roll' h, owever, is broad enough to eiitend across both cams,-wherefore should one cani 4be shifted beyond the other, the eii'ective is; .ength ofthe cam is increased up to a maxiiiiutn of-'twice the length of either cam member. By this means the paper feed may -befheldoutlof act-ion for as great or short period as desired.' One of the cams is lstationary and is of a'length corresponding 2519-, and 11. In the end member o the drum, adjacent to the surface` b on which the cams seat, is a recess adapted to be occupied b i blocky L. This block has a shoulder or ri l along its upper edge which isadapted to occupy a 'correspondin notch in thecam rin K ,thereby securely ocking this -rin to t e d rui'n. The block extends o'iitwar y beneatlithe cam ring K. In the block is a threaded hole which is occu ied b n,-"-"cap screw l. This screw passes t roug an Lsha ed cli l, which bears on the outer side of t e bloc and against the cam ring K and projects into the recess beneath the block, thereby holding the rib l inthe notch in the cam ring K. The cagi vrings are held by the gear b and the okl of the drum against movement longituia ly ofthe The block holds t e ring'K against rotative movement, and the cam ring K holds the block against displacement by .rea-son of the shoulder Z. Whe n the cap screw Zfis loosened, the 'cam rin K is therebyl unlocked and may be shifte circumferentially to shorten or lengthen the effective 48 cam, as desired. A recess k is made in the `inner face of this cam to allow the' insertion Y oiga-screw driver or other tool for convenz iently shifting the cam.

'B reason-.of` lthe 'L -shaped clip I, the- I locking block L ma be easily putin place. The height of the s oulder l is slighy less than the thickness ofthe piece l. herefore when this piece is removed, the block may be slid into the recess beneath the cam rin K, the block then being moved outward ra ially, the rib l passes into lplace behind the' ring' K. The ieee Z* is t en put' into "lace as a filler to old the block in this position. 1

i60 When-the movable cam K has been adroperlytime the paperjusted and locked to feed according 'to t e letter head on the paper, a rotation of the drum causes the apex' to be 'fed rearwardl rum and platen, one or botl edges of the 'a belt pulley. `A belt gi t.

between the,

paper passin between the strips ofthe edge guide or gui es. In such operation, it sometimes happens that the friction of the sheet of paper develops suilicent frictional electricity to give it a tendenc to cling to the plrinting drum, so that as t e paper emerges om the guiding stii s, it is carried around toward t e front o the machine by the printing drum,V and iin-less removed, will a ain pass through the printing mechanism.

is diiilculty does not ordinarily occur, but

in cold dryweather it sometimes happens,

especially if the pa er be light and iiexible.

To overcome the di culty mentioned I provide an ejeeting mechanism adapte to receive the paper as it is emerging from the 'printing couple, and prevent its wra ping around the drum. This mechanism is s own in Figs. 2,' 5, 6, and 7. Mounted on the end frame member Ais a4 pinion p which carries connects this with a pulley p2 on the sha p which is carried between tlieframe members, extendin parallel Awith the platen, as shown in ig. 6. This shaft is carried at one 'end by a removable stud p, extending into an opening in the shaft and at the/other end by 'a screw p, which projects, ito an opening in that end of the shaft. This shaft p carries rollers Pwhich pro'ect upwardly througlh open- 96 ins in* the tab e A". Extending orizonta y across the machine near its rear edge is a rod .Q on which are slidabl mounted ariiis R in the form of cages w ich carry freely 'ournaled rollers S adapted to bear upon t e rollers P. `The pa er being fed rearwardly in a substantie horizontal plane along the top ofthe table, runs between the rollers S and P, which continue to guide it so that when the paper is freed 105 rom the guiding strips, it is not able to come up onto the drum and cling thereto.

As heretofore stated, the bands F` which I have provided allow matter of various size to be locked on the drum. For example, it may be desired to print postal 'cai-ds. -In this case,lone of the bands ma be near the. end of the drum and the-ot er near the middle. Where the type page is of this short width, the paper is of correspondingly narrow width, and hence isided by only one of the guiding clips at t e ends of the platen. When the paper ejector is used, onl one of the end rolls P would come into action with such narrow paper. I. accord-'120 i'ngl provide one or more intermediate rolls. In t e embodiment shown, there is one intermediate roll -1: which is ordinarily suf,-v

eient, as it is seldom desirable to print on 1 paper materially less" than half Ithe width ,ofA the drum. But two rolls S need be pro-1 vided,l 'because their car ing members-R I are slidable upon the roda, So that the two rolls 'S may be made to copera-te withany twoof the rolls P, according to the position 1430 tion of a printing memberhaving lon tudi nal type holding channels, type in sai chan of the bands F on the printin drum. To

furnish convenient means for s lifting these` rolls S, I form tails or extensions ron the members R by which they may be easily taken hold of by the fin ers. etween the two ears of the cage, whic surround the rod Q, I place a split. sleeve r which engages this rod with sutiicient friction to prevent accidental dis laceinent of the cage 1, while allowing it tolbe shiftedv when desired.

The arts constituting the paper ejector are ma e so that they may be conveniently removedwhen it is not desired to use them. When they are in place, it is simply necesto thirr rol sin accordance with the osition of the bands F and theej-ector is ready for use.

The ejectingmechanism per se is covered in `my divisional application No. 459,343, filed Oct. 24, 1908; it is claimed herein only in combination with the printing couple and th nlutually adjustable marginal band.
