' ribbon, and particularly for the production of personal or, individual typewritten letters.
One object of the invention is to, provide an apparatus of this character, which will be simple in construction and easy to oper-' ate.
A further object'is to provide improved mechanism by means of which the name and address of a different firm or individual, spaced fromthe body of the letter, according'to'the regular typewriter line spacing, may be printed in'succession from separate and, disconnected name and address forms, through a typewriter ribbon upon each individual letter, and at the same time, and in uniformity with the printing of the subject matter or body of each letter, so as to present a series of'complete personal typewritten communications, each properly ad dressed and individually written to a different person or firm.
A further object of the invention is to provide improved mechanism to automatically change the name and address, with each complete operation of the printing mechanism. I
A further object is to provide mechanism for printing, inuniformity with, and at the same time asthe body of the letter, and the name and address, etc., the proper salutation, such as Gentlemen Dear Sir etc., properly spaced from andintermediate between the letter and the 'name and ad dress.
A further object is to provide mechanism for properly feeding the paper and registering the margins from the top, bottomor sides of the sheet at which the printing is done, and for automatically bringing in succession the different sheets of paper into printing position, as they are placed by ha 11d 0n the paper. table, "and so that the pr ntlng may be done in the same relative position upon the different sheets of paper, sald mechanism being capable of adjust, -ment so that the printing position on the paper may be varied as desired. 7
A further object is to provide mechanism whereby each sheet of paper is automati cally picked up from the type bed as it is" printed, "taken around the printing roller and after being turned over and the printed matter brought face up, ejected from the machine into a letter chute or other recep tacle provided to receive the same.
A further object is to provide mechanism whereby the automatic means for changingthe names and addresses by each completemovement of the printing mechanism, may
, be temporarily rendered inoperative, so that any number of letters 1 bearing the same name and address may be prlnted 1n successlon, the same mechanism being used to again intermittently change to a new name and address whenever desired by each ope-ration of the printing mechanism.
A further object is to provide an office printing machine which may be -used with ease Without the usual printing ofiice training, for printing oflice forms from type of any. style, electrotypes, wood cuts or type surfaced material of anykind, either by use of an inking ribbon or. from printingink applied directly to theface .of thetyp'e,- surfaced material when the ribbonortype writer effect is not required. v V
A further ob'ect is to "provide mechanism for printing in uniformity with, and atathe same time as the body 'of the letter, the city or street address of the writer, the date, -etc.,
properly spaced above the name and address of the party to'who'm written, and whereby the position of the date, streetaddress, etc.,
-may be varied as to distance therefrom .or

. Referring to the drawing, 1 indicates a frame supported upon legs 2, comprising sides 3, and end plate 4. Secured upon said side plates 3 are horizontal bars 5 formed with seats 6 to receive the chase or type form holder 7. The two bars 5 at the ends of the chase 7 are also formed with seats 8 to receive the ends of the chase 7, and through one of said end bars is secured a locking screw 9, which screws into the end of the chase 7 and looks it firmly in position, while by loosening said screw 9, the chasecan readily be removed. In said chase are set, in the usual manner, the type 10, and over said type extends a broad ribbon 11 of transfer or inking material, wound on ribbon rollers 12. Each ribbon roller is formed at the end with a central cylindrical. recess 13 (Fig. 5) adapted to fit snugly over a flanged head 14 on a fixed shaft 15. When said recess 13 is placed over said head the corresponding end of the roller .12 can be pressed against a disk l4 through which passes the shaft 15 which disk is pressed outward by a? coiled spring 17 around said shaft. The roller can be moved in its axial direction against said spring sufficiently to allow a transverse groove 18 formedinthe "opposite end of the roller to receive a trans- 5'5 verse or diametrai rib 19 formed upon the face of a disk 20 secured upon an end of a shaft 21, which, at its other end, is mounted in a bearing 22 supported by a side plate 3 of the machine, and said shaft 21 has se-- cured thereon a. ratchet wheel 23 for the purpose of turning said shaft as hereinafter described. The necessary friction to resist the rotation of the ribbon roller, except when rotated by some positive mechanism,
is provided by the pressure of the springmaaese thus maintaining a suflicient tension upon the ribbon to take up the slack.
The printing is effected in the follow ing manner: 24 indicates a pressure-roller, having preferably a rubber surface 24 (Fig. 4), and loosely mounted upon a shaft 25, the ends of which shaft are secured eccentrically in disks 26, as shown at 26 mounted in boxes 27, which can move vertically in guideways 28 formed in the side plates 29 of a carriage 3,0. Said guideway is closed at the top by across head 31, through which is screwed an adjusting screw 32 having a suitable milled head 33. The bottom of this screw bears upon a fiat bow spring 34 which in turn bears upon the top of the box 27, while said box maybe pressed'or raised upward fromjundue or irregular pressure from the underside, by contact of the pressure roller with the pressure relief lifts hereafter described. By adjusting the screws 32, the desired pressure of the spring 34 on the boxes 27 can be obtained.
The two side plates 29 are connected by rods 35 which extend across the machine to form a carriage 30 and a handle 36 for moving said carriage in either direction is secured thereto at '36.
In each end of the carriage 30 are mounted four rollers, two upper rollers 38 and two lower rollers 39 (Fig. 3). The upper rollers 33 are mounted on shafts 40 secured directly to the side plates 29 of the carriage 30, onein front and one behind the center of the carriage, and the two lower ro lers 39 are mounted upon shafts 41 securec toplates 42 secured to the side plates 29 by screws 43 which pass through slots 44 in the outer plates 42 and thus permit of verical adjustment of said outer plates. Said iand, since, by means of the adjusting screws 46, said rollers can be arranged to press done.
intense tightly against opposite sides of said rail 4:7, the carriage 36 can be moved without undue lost motion or the slightest variation of pressure upon the ribbon and type 10 during its entire travel/ Upon the roller shaft is carried, in the manner hereinafter described, a depending arm 49, the lower end of which, in the printing moveof the roller 24, rides upon a track or cam 50, secured atone side of the machine frame 1, and extends through a distance corresponding to that part of the travel of the carriage in which the printing inay be Said track comprises the main grooved portion 50, the top of the extension being flush with the top of the main portion, and arranged to be held at any desired extended position, so as. to lengthen the track more or less, as desired, and the arm 4:9 is sufficiently wide at the bottom to engage either the main portion 50, or the extension 51, or: both.
' It is desirable to secure the arm' 49 adjustably to the eccentric bushings 26 to which the shaft 25 is secured as shown at 26 and is raised or lowered through the turning of said bushings 26 in either direc-v tion, so that the distance of the lower end of said arm from said shaft, maybe varied to correspondingly vary the amount through which the eccentric bushings 26, to which the shaft 25 is secured at 26* are turned, and thereby correspondingly vary the pressure of the roller 24: upon the type 10., For this purpose, the upper end of" the arm 49 is slotted as shown at 53 and is slidable over a squared portion 54 on one of the eccentric bushings 26, and upon which said. slotted end of the arm 4:9 is securedby an adjusting screw 55, the lower end of 'Which rests upon the top of the eccentric bushing 26. Secured upon the slotted portion of the 4.9 at one side thereof is a clamp screw 56 for the purpose of clamping said arm 29 to the eccentric bushing 26 and thereby locking the arm -l9 from longitudinal movement, except when it is desired to change the adjustment thereof. When this clamping screw 56 is loosened from the eccentric bushing 26, the adjusting screw can be turned in either direction and therebodily move the arm 49 longitudinally relative to the shaft, thereby lengthening or shortening the distance of its free end iIOIll said shaft, thus regulating the .dis-
which'the shaft 25 is secured, are and thus varying the-pressure of the elas hereinafter described. /Vhen said arm passes over the end of the track returns to a central or intermediate sition under the pressure of one of two 'ings 60, secured to the carriage frame, cn each side of an arm 58'. Then, on ie r at, o
, through which the ecoentric'bushings eturn movement of the carriage 30, the
lower end of arm 49 abuts against the end of the cam or track 50, and is ,thereby shifted rearwardly so that it again rides upon the track 50, but with a rearward obliquity. Upon the arm 49 being turned from its former position the eccentric bushings 26 to which the shaft 25 is secured, and
upon which the roller 24; is loosely supported, are turned about their centers, and
thereby said shaft 25 in said return move-' taming paragraphs, the short line at the end of a paragraph is printed heavier than when there is a full line of type, owing to the fact that the whole line of pressure 1s supported by said short line; the sa1ne-being the case in regard to the beginning of a paragraph,
when the first line thereof isnot begun at the extreme edge. This is also the case in regard'to the prefix and aflix of a letter, or other communication, which do not occupy full lines, and which, moreover, are frequently written wider apart than the main body of the letter. This wider spacing also occurs betweenparagraphs when the main body of the letter is written single spacing,
and the paragraphs separated by double spacing. In all such cases, in order to pre vent excessive pressure at these points, I provide pressure relief lifts 62, which are in the form of thin yoke-shaped clamps, the sides 62 of which clamp the vertical surface 7 of the sides 7 of the chase 7 while the middle 6?) lies upon themit'op ofsaid side 7 The tops of the slides 7 of the chase are of substantially the same level as the face of the type, or a trifle lower, but the pressure relief lifts 62v are for the purpose of slightly T raising the roller at those points where they are placed, so as to partly support the pressure roller, and toprevent the full pressure of the roller being imparted to a part only of the line of type. The pressure relief lifts 62 may have such contour as not to form a decided obstruction to the movement of the roller.
It is for the purpose of allowing the pressure roller 24 to rise slightly when passing over the pressurerelief strips 62, that the bow springs E i-are provided and the tops of the boxes27.
The inking ribbon 11 is 'extremlysensh a r u Thesheets of paper 199 are fed one at a time by hand, on to a sloping table 64, carried with thecarriage 30 by means or" arms 65 extending therefronr. The table 64, is cut out at its lower portion, as shown at 66 (Fig. 5), to permit the sheets of paper after being printed. to pass therethrougrh as-they are ejected from the machine. The paper is fed on to said table '64 from one side, (here shown on the left) and is arrested at the other side of said table by an adjustable side guide 67, against which the edge or" the paper is placed. In its descent the lower edge of the paper is thus guided between said roller 24 and a small feed roller 68, carried adjacent to the roller and above the type 10 by arms 68 (Fig. 3) secured in bearings 68 to the sides of the carriage 30 and held in frictional contact with the pressure roller by springs 68. The lower edge of the paper 199 thus passes into the space between the guide roller 68 and the pressure roller 24, and when the pressure roller 2%, through the-action of the arm 49, and the movement of the eccentric disks 26 is brought into contact with the sides 7 of the chase, so that it begins to roll through pressure thereon, said rolling movement causes the small feed roller (38 to revolve in unison therewith and thus feeds said paper 199 be tween thepressur'e roller 24 and said teed roller 68 which is revolved by t'rictionai con tact therewith. he paper 199 is then guided upward and around the roller Q i by fingers 72 one at each end or side of the roller and extending around the same at the opposite side to that at which the paper is fed. The pressure roller or platen, it will be observed is of such diameter that it makes more-than a single revolution in its printing stroke, and while engaging the paper sheet, thereby particularly adapting the device to the production of close simulations to real typewriting while being contained in a carriage of relatively small compass and weight.
The printing on the paper 19.9 from the type 10, through. the inking ribbon 11 is done by the pressure of the roller 24:, and
each sheet of paper 199 is automatically lifted from the type or inking ribbon through the movement of the can by the following mechanism. Adjustabie to one of the transverse stay rods by means of set screws 71 are attached two paper tingers 72, the. lower ends of which extend within the chase 7, close to the sides thereof, and underneath the pressure roller 24. When the carriage moves from its terminal position, the first efi'ect otthe movement is tobring the arm 49 into contact with the or track 50, to cause the press to bear upon the sides *3 of Thereupon the pressure roller is frictional revolved, and with lilillQ p per ieed roll 1 68, causing the paper to be firmly held ied between said pressure roller and the roller 38. The fingers '43 pass below t roller Z i and extend forward shown i' 72, so that the adva ting iower end of =11. paper 199, after it has passed EOE/L- rollers and 88 upon its further slides upon. the fiat surface of said on Y2 and is guided upward and aroum rear of the pressure roller, between it a said fingers 72 and thereby around roller. By this movement the paper is ried upward, and as the end of the sheet paper, continues to advance under and around the pressure roller, through the further rotation thereof, passes from between the pressure and feed rollers, so that with. this frictional movement together with the weight or momentum of the freed sheetot paper, it is carried forward thereby and ejected from the carriage into a paper chute 73 secured to the end of the frame.
The parts of the frame 50 cooperating with the pressure roller 24: are made of? a suiiicient length that the roller will rotate long enough after passing the final print ing; point to continue to advance the paper suiiiciently to discharge it into the chute This part of the frame 50 corresponding with the sides of the chase 7, can be extended the full length of the frame, in which case the sides of the chase would he lowered.
in order to maintain the inking ribbon 1'3. sufficiently fresh to furnish a good impr s sion, and one which will print equally heavy at the top or bottom of a sheet of paper, the ice ribbon 11 should be advanced somewhat rapidly, the advance being, of course, intermittenaand taking place only at the end the movement of the carriage when the printing is not being effected. The advai- 110 is performed by the carriage 30 coming in contact with the upper portion of one or the other of two arms 7'4". which are pivoted on brackets 22 on the frame of the machine. Te arms 77 are pivoted toothed pawls 79, either of which may be held in contact with a ratchet wheel -'23 secured on a shaft 21, upon which. is secured the disk 20 which fits upon theend of the ribbon roller 1'2. The toothed pawls 79 are held in contact with either of the ratchet wheels 23 by means of springs 80 secured thereto, the other end oi which is secured to the bracket 22. As only one toothed pawl 79 can be used at the same time, the pawl not in use is pushed back and held by. a catch 81 secured on the ends of me framerso that the teeth of the pawi are out of engagement with the ratchet wheel 23, and thus do not interfere with its movement as the ribbon is unwound from the ribbon rec sides in the mechanism by which different spool connected therewith. The pawl 79 is provided witha number of rack teeth, as shown in Fig. 4,.which gives prolonged en- I gagement thereof with the ratchet wheel 23,
such engagement enduring for a considerable portion of the stroke of the carriage; thereby the ink ribbon is advancedfarther than would be the case if the pawl consisted of but one single tooth.
An important feature of the invention renames and addresses can be printed uniformly with the main body of the letter, and are changed automatically with the printing of each sheet. Another important feature consists of the mechanism by which a proper salutation, such as Dear sir':', Gentlemen Madam et cetera, may be, at the same time printed according to regular typewriter line spacing intermediate between the bottom or lowest line of the address, and the first or uppermost line of the letter.
In order 'to prdduce individual typewritten letters, it is ,essential that they be in every particular identical with the work of a standard typewriter; that the left hand margin aline exactly, both with the body of the letter, the Salutation, names and address, etc.; that the spacing between the different lines correspond with the regular spacing of the typewriter, and the spacing between the different lines for the name and address, salutation, etc, correspond with the spacing of the different lines of the letter, and with the line spacing of the standard typewriter. For this purpose there is provided a sleeve 91 rotating in' a bearing '92 fixedly secured upon a transverse bar 93 (Fig. 6). In this sleeve 91, is one end of a shaft 94, movablelongitudinally in the sleeve, but rotatable therewith by means of a pin 95 in the sleeve engaging a slot 96 in the shaft. Said shaft has its hearing at the other end in a support 97 adjustably' secured on the transverse bar 93 by a set screw 98. By this arrangement, the shaft 94 can be moved transversely of the machine to any desired position within suitable limits, but in any position it still rotates with the sleeve 91-. Said shaft 94 is movable transversely of the machine in order to permit ofvarying the distance or margin, from the edge of the paper 199 atwhich the name and address begin thereon,
so that said nameand address' may aline with the left .marginof the printed matter on the sheet. Upon'said shaft 94 are secured carriers 99, there being'here; shown two, although more may be used or one could be m'ade to extend the entire distance between the two. Each carrier 99 has in its rim four recesses each of which has a 'fiat surface 102, 7 two slightly sloping sides 103, which in succession, as the shaft turns by means presently described, form a seat:
or cradle 100 adapted to enter corresponding "here shown are spaced apart by what is known as single typewriter spacing; at the same time I do not wish to limit. myself to any particular width of line spacing. The spac'in' between one paragraph and the next is dou lev typewriter spacing, or 'twice' the single typewriter spacing. Between the first line of the letter and the salutationis double typewriter spacing, and between'the salutation and the lowest or bottomlin'e of the address is double. typewriter spacing. The
spacing betweenthe name and address may be single or double typewriter spacing. As
- this i spacing should be rigidly maintained,
the space for-the rotation of the shaft 94, the name and address holders 105 thereon,- with the type 112 in said holders, is necessarily limited; I therefore provide special means to prevent thefa'ce ofvthe type 112 from striking or rubbing against the'front end of the chase 7, or other parts of the ma.- chlne. As the type 112 used in the holders are made of ordinary type metal, the
striking or rubbing of its face would serig ously damage the same, and thus destroy the utility of the invention for this particular work. The holders 105 are so shaped at their sides 106 and grooves 104 that the bottoms of the recesses 102 and the sides 05 103 in the form holder seats 100- on thecarriers 99, fit into said grooves 104 across the bottom of name and address holders 105, and the ends or sides 103 of such seats fit snugly the slightly sloping sides 106 of the 110 flame and address holder 105 so that each --name address holder is properly seated and firmly locked therein by means of the side guideways and the pins or studs 118.
the rotation of thename and address holders 105, by use of the specially shaped support or holder 107, upon which at 108ris supported the typeface for any desired salutation, to print the same spaced correctly and 120 properly intermediate between the address and first 'lineof the letter, without interfering in any way with the rotation of the shaft 94 or of the type 112. in the name and seated inside of the chase 7 in line with the first row of type, but the same can be removed therefrom and replaced with one having a different Salutation without any ad- 30 2/ It is also possible, without interfering with 115v address holders 105 supported thereon. The V Salutation support or holder 107 is firmly by means to mes es g any part of the type It can ited out and replaced instantly withou any adjustment. Said holders 105 are ered to said carriers 99 l described, and, I '2; advanced by "hich is ro- 9 1 is seiour teeth justment, or form.
when supper the rotation o tated'as folio. cured a ratchet 109 adapted to carried upon he carriage 30, so 91cm 7 24; has passed. over Q pe 112 and completed the printing of the name and address, said pawl 110, in the further advance of the carriage 30, engages one or said teeth 10%},
and turns the shaft 9% through one-rourth.
of a revolution, which it escapes engagement with said ratchet tooth 109. flhis movement brings the next name and address holder 105 into proper position for printing. Upon the return movement oi the carriage 30, said pawl 110 rises and passes over the tooth 109 and has no efiect in turning the shaft 94f In order to hold the shaft firmly, and prevent any rotary motion thereof except when rotated as above described, there is provided a'lever lock 111, actuated by a spring 113, and having at an intermediate point thereof a square nose 114 adapted. toengage any one of four recesses 115 in a disk 116 which is a part of the ratchet wheel 90. Said lever is, however, extended beyond said nose 114i, and is adapted to be engaged by the pawl 110, as it advances to turn the shaft, the engagement having the effect of lifting the nose 11 1 out of the recess 115, and unlocking the shaft 9 2, before the pawl 110 arrives at the tootm 109 of the ratchet wheel 90 and thus turns said shaft 94. The pawl 110 may be thrown up when it is desired to print several copies Without advancing the address forms. A quantity of letters may therefore be printed with the same address if des red.
Each holder is formed with threeparallei undercut grooves 117 for type 112-, the
is suitable for printing the standard double typewriter spacing the grooves 117 being. made a distance ar-r to correspond ex-L actly with the regular typewriter spacing between the lines, either singleordoublev spacing.
Each holder 105 is also -formed at each end with two longitudinally extending guide pins or studs 118, the function of said studsbeing to guide the holder when being delivered to the carriers 99 by the delivery mechanism hereinafter described, and in so guiding it to confine it to the proper path along the giideways .120 hereinafter described, so that the face of the type 112 carried on the holder 105 will be placed outward, between the side guides 1 0, so that there can be no possibility of the face of the type 112 coming in contact with the front of the chase 7 or any pr i the apparatus.
120 indicates two vex-ti a at tached near their upper s to a cross head or plate 121 to which is additionally supported the top of a rear guide 122. @n
said rear guide slides an elevator 1:23, having lateral pivot pins 124, to which are which are pivoted lever arms 126, upon a rock shaft 127 operated by a link 128 con nected to a slide 1 9 which slides through guides 180, to which slide 129 are adjustably secured bumpers 131, which are adapted to be operated by a stud 132 extending laterally from the carriage 30.
The side guides 120 adjacent the printing seat overhangthe studs 118 on the name and address forms, as illustrated in Fig. 6 and thereby confine them against accidental dislodgment, and the wall portions of such guides which lie adjacent the opposite ends of the forms likewise aid in determining the position of the form, when in the printing plane, cooperating with and supplementing the alining and positioning functions of the cross-bearings 10 1-, described below, on the bottoms. of the forms. The address form is thus brought to position under con form being thus similarly and precisely located, a matter of much importance.
The name and address holders 105 are contained in drawers or boxes 133, open at one end, and having rails 134; extending inwardly "from their sides, upon which rails the pins 118 of the holders rest, and rails 134s on the bottom so that the grooves 104 of the holders 1055 slide thereon, so that the bottoms of theholders except at that point are out of contact with the drawers or boxes. They are fed to the machine by placing one of the drawers or boxes 133 on an inclined support 135 supported on the frame or legs of the machine, and so that the open end of the box is in front of an opening 136 beneath the vertical guides 120 and above a front wall 137 which is supported upon a movable seat 138, Said seat is connected by Springs 139' with the rear guide 122, said springs being secured at the bottom to pins 140 extending outward from the seat 138 and at the top to pins 1 11 'extending outward from the guide 122, so that the springaltl) normally tend to raise said seat 138 and thereby. to raise the front plate 137 and cut off the-supply of holders 105. When the elevator 123 arrives at its lowermost position, the boifiaom of the ele vator abuts against said seat, and depresses.
tom of the elevator-.123. When it so passes,
the front or foremost end of the holder arrives at the upper part of an oblique surface- 143, formed on the lift 142 and, as-the lift 142 rises, the pins 118 at the front or foremost side of the holder 105 are guided in a funnel-shaped portion 144,0f the side guides 120, so they are brought uppermost,
and thereafter the lift 142 raises said holder 105, so that the type 112 on the holder, face outward or toward the front and between the side guides 120. As soon as the elevator 123 rises from the seat 138, said seat is raised by said springs 139, so thatthe top of the front plate 137 rises above the level of the bottom of the inclined carrier support and the holders 105 in the box .133 can no longer be fed until the seat 138 is again depressed.
' With each complete vibration of the lever.
arms 126, a holder 105' is lifted substantially half way up the guides 120, and at the end of said upward movement is retained against dropping with the return of the elevator 123, by means of spring actuated catches 145, which extend into the side guides Said elevator has secured thereto a forwardly extending portion 146 upon which is pivoted a lifter plate 147, the lower end of which is normally pressed backward by a fiat spring 148,. .so thatthe upper end extends forward. -As the elevator is descending, the upper end of said lifter plate 147 passes on the rear side orbottom of the 'holder 105 which has been lifted half way, therefore out of contact with the type 112 and, then beneath said holder, to normal position. Upon the next.
upward movement of the'elevator 123, said lifter plate 147 now lifts the partlyraised holder 105 through the remainder of its ascent, and brings it up to the carriers 99 on the rotary shaft 94. As it is brought opposite to the vertical front carrier seat 102),
of said carriers 99 the pins 118 of the holder 105 are engaged by springs149, and are pressed rearward thereby in succession first the advanclng and then the succeeding pins,
so that the holder 105 is properly seated and locked in position through the grooves 104 and the carrier seats 100.' From this point the guideways 120 continue around the carriers 99 in a curve as shown at150. Upon the next movement of the carriage 30, .the carrier shaft 94 is as already explained. rotated one-fourth of a revolution, bringing surrounding the shaft 156.
the holder 105 into printing'position 500. (In order to insure the exact seating of the holder 105 in the carrier seats 100, and to lock the same therein, springs may bear upon the pins 118 of the holder, and thereby press the grooves 104 of the holder 105 down upon its seats 102 and the sides of the holder so they firmly lock, it, in its printing position 500.)
Upon the next movement of the carriage 3'0, thecarrier shaft 94 is again rotated through another quarter of a revolution, so that the holder 105 is moved to a vertical position 500 upon the rear side of the carrier 99 and'the carrier shaft 94, and the next holder 105 is brought into printing position 500 in the same manner. Upon the next movement of the carriage 30, the
carrier shaft 94 being againrotated througha quarter of a revolution, said first holder 105 is released from'thecarrier 99, the carrier seats 1.00, and said lifelder 105 now 105 is thereby discharged and slides into an empty drawer or box 133 placed there to receive the same.
For the purpose of applying an autov graphic signature in ink to the letter so, printed, 1 provide a signature roll .cial slideway or track 159 at a predeter-.
mined pointin the travel of the platen carrlage thereby, vibrating or rocking v saideccentric disks 1 57 and bringing. the rollers 160 which-are also mounted loosely on the shaft 156 and connected to fllhQ. signature roll, into contact with the platen roller 24 causing sa d signatureroll 155 to i 5'?" tate in, unison with the pressure I roller ture roll""15,. so as to rotate thetlatter. as
descrlbed,-. the connection comprising necks reduced parts 155*ex-tending between said rollers160 and the signature roll and The said are duced portions of the signature roll which connect the body thereof with the parts 160:
are necessary in order to provide clearance slides by gravity down curved guide grooves f 153 which receive the pins, and the holder 1194 .24 through a complete' evoiutim'i of the for the end paper guide fingers 72, and also in order that the signature roll shall receive one-complete revolution for each printing strblre of the carriage and thus be left in the same angular position after it has com pleted the operation of afixing the signature. Figs. 13 and 14 illustrate a detail of the signature roll, 162 being a curved plate slid endwise into under-cut grooves formed in the body of the roll. Ti lie surface of this plate is formed to have contact with the platen roller and print the signature there on, while the rest (161, Fig. 14:) of the roll uncovered by the plate 162 has no contact therewith, as will be evident. The nucleicut grooves extend the full length of the roll and the signature plate 16:2 is adjusted thereon to bring the signature at the proper distance from the margin of the printed sheet. As the paper moves upwardly on the platen and beneath the paper guide fingers 72, the pressure roll,- or rather the signature plate thereon, is automatically brought into printing engagement therewith and prints the signature at the foot oi the paper sheet, while the latter is in motion and being removed from the printing plane. The necessary pressure for so printing the signature is derived from the action of the eccentrio arm 158 coming against the special. track 159. This pressure can be varied through the movement of the eccentrics 15"! either by lowering or raising the track 1? or by lengthening or shortening the arm 158. The means for so lengthening or shortening the arm 158 may be precisely like those already disclosed for the lengthening or shortening of the arm 49 of the main pressure roller 24, and 1 do not deem it necessary to repeat such description for the signature roller. The signature roll is kept supplied with ink by an inkingroller 164, which is rotated by contact therewith, and also runs in contact with an ink roller 108 which dips into an ink-well 167 (Figs. 3 and 4:).
Figs. 18 and'19 represent a modification of the present invention in which the name and address holders 171 are pivotally connected to each other at their ends to form a chain, said chain carried around the shaft 94: by the cradles 100. The transverse bars 172 are of greater length than the name and address holders and the ends of the bars are adapted to slide in their upward and downward movement in suitable guidcways 175 in the guides 173 so that the name and address holders are rigidly locked on said cradle during the printing movement, so that the type in said holders are prevented from coming in contact with any part 01' the machine during the movement oi the name and address holders. are suitably locked to the bar 93 by said screws 174-.
The date line is seen at 17 6 and is covered by the inking ribbon. The address forms occupy a position between said date form and the main form. The date line is carried in a holder 177 resting upon a pair of supports 178, Figs. 4 and To adjust the date form forwardly and backwardly, so'that it may register with any printed line upon the sheet to be printed, the holder .11? is secured adjustably to the supports The guides 173 0 by means of screws 179, which pass up rough'slots 180 in the holders 178. It will "sen that the chain guide 153 is bowed vardly at 153 to clear the date line form,
.fficn the ribbon is disconnected from the machine, the carriage shown at Fig. 17 may be substituted for the other carriage and the types may be directly inked from the fountain 167.
it is to be understood that when the inking device shown in Fig. 17 is employed, the signature roll 155, is not employed, the signature in this instance being produced b suitable types or other printing surfaces forming part of the matter in the chase 7. 1n the construction shown in this figure, the ink roller 164.", runs in direct contact with the ink 167, and atransfer or distributing roller 16-11", that runs in contact with roller 164:, applies the ink to the inking roller 166 The signature printing device herein de- .scrihed is also shown and described, and
certain features and developments thereof are claimed, in another copending application, Serial No. 589,405, and certain features of the lateral adjustment of the address-printing mechanism and conveyor mechanism are likewise more fully described and claimed in the said co-pending application.
