PRINTING-MACHINE.

Specification cf Letters Patent.

Patented Sept. 18, 1906.

Application filed August 19,1905. Serial No. 274,881.

nois, have invented a certain new and useful Improvement@Printing-Machines, of which the following is a specmcation.

The olnect of the present invention is to provide a simple yet effective mechanismfor printing from a form of type, such type being either of the character commonly employed in printing-presses or, if desired, of the character better adapted for setting np by nnskilled hands and having a printing-face at one end and a display-face at the other. 1n carrying out the invention to this end I employ a suitable frame having a vertically-ad-4 justablepressure-roller and means for throwing the same to operative and inoperative positions. Coacting with such frame is a carriage adapted to receive the chase in which the form of type has been set up, and inter# mediate of such form and the vertically-adinstable pressure-roller I employ an ink-ribbon carried, preferably, by a rollat each end of the carriage, suitable mechanism being combined therewith for moving .said ribbon step by step at predetermined s eed, so as to present a fresh surface thereof or successive rinting movements of the carriage and the orm of type supported therein.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation vof a printingmachine employing my invention. Fig. .2 is a central longitudinal section thereof.- Fig. 3`is a plan view, certain portions being shown in section. Fig. 4 is a detail vertical section on the line 4 4, Fig. 3; and Figs. 5 and 6 are detail views illustrating portions of the ribbon supporting and operating mechanism.

Referring to the drawings, in which similar letters of reference denote corresponding parts, the frame of the machine comprises, generally speaking, two side plates A A', which may be provided with cross bars or braces c a. Said plates are provided with vertical slots a2, through which extend the ends of the shaft b of the pressure-roller B. The ends of said shaft arejonrnaled in arms C C', each of which is pivoted at c to the outer face of one of the side plates of the frame, the distant end of each arm being downturncd, asshown at c', and provided with the toe c2.

frame.

D designates a shaft ionrnuled in the side plates A A and projectingr therethrough, the ends of' said shaft being provided with cams d, said shaft and eums being operated, by means of a suitable finger-piece to bring the cams d into eoaetion with the toes ci of the hinged arms to thereby elevateI and depress the pressl'lre-roller B, throwing the same to operative. or inoperative positions, as

desired. Pivotally mounted lat. c upon the outer face of each of the hinged roller-carrying arms is a loelt E, the lower end whereof is provided with a linger 1', adapted when said lock E is rocked upon its pivotal point (the pressure-roller B being depressed) to eoact with theshaft l). Each of said locks E.

includes an upward extension f2, projtw-ting into the path of a sto i formed upon the carri age, as presently exi'ilained. The lower arm e of each of said locks coacts with a guide- Stop e, limiting the movement of saidlower arm e3.4 Coil-springs F l", the lower ends whereof are connected with the hinged rollervcarrying arms (l C and the upper ends with adjusting-nntsf, serve to exert upward tensionupon said arms and to movel the pres sure-roller B to operative iosition.

The carriage overlying the mechanism just described includes the side members G G and the end members g g. Adjacent to their lower edges the side members G G are provided with guide-ribs g2, coacting with rabbets or grooves g:i in the plates A A of the Each of said side membersG G is also provided with a rack g4, -which coacts with a pinion g5, carried by the shaft b of the pressure-roller B, so that as the carriage is moved forward, the racks' g4 and pinions g5 being in engagement, the pressure-roller will be driven. This, however, does not apply to the rearward movement of said carriage, since the pinions g5 will be thrown out of engagement with said racks, ashereinafter explained.

Supported by the carriage in any suitable manner is the chase in which the type are sot up. This may be of any desired construction, and I have here shown, merely for the .purpose of disclosure, a rectangular chase not illustrated in the drawings.

same have been set up from being pushed up-A wardly during the printing operation.

I here remark that it is obvious that, if desired, the interior of the chase described may be removable,so that a 'chase either of the construction alluded to or of another and different construction maybe set within the same and securely fastened in such position. These and other details in connection with the form of the type-supporting mechanism may be varied at will without departing from the spirit of the invention. The chase may be secured to the carriage in any suitable manner-as, for instance, by the latches h4.

At either end the carriage is provided with brackets (preferably adjustable) carrying rolls or spools on which the ribbon I may be wound. The brackets L L at the rearward end of the carriage are provided each with the upwardly-extending portion Z and the angular downturned portion Z, the forward end of the latter having the beveled portion Z2, its outer face carrying the lock-operating boss Z3, coacting with the upper end c2 of the lock E. The beveled portion Z2 of each bracket L coacts with a sheave Z5, carried by an ear Z6 on one of the hinged roller-carrying arms C C', so as to depress said roller in advance of the coaction of the boss Z3 and the arm e2, such coaction resulting in moving the locks E on their pivotal points e and throwin the fingers e into engagement with the sha t I), thereby locking said pressure-roller in inoperative position at the conclusion of the forward (printing) movement of the type-carriage. Each of the brackets Lis providedv with the set-screw Z4, engaging with one or another of a series of threaded orifices Z7 in the side men'ibersG G of the carriage.

Mounted upon the upwardly-extending portion Z of one of the brackets L is a sleeve m, through which extends a stub-shaft m', to the outer e-.id whereof is keyed or otherwise secured a knurled nut m2. Keyed or otherwise securedto said sleeve m is a ratchetwheel m3, with which coacts the upper end of a lever m, pivoted upon said stub-shaft m, vits lower end projecting downwardly and adapted to coact with a stop-pin m5, carried on the outer face of the frame-plate A. Inside the bracket L the sleeve mis provided with a clutch member m", inwardly pressed by means of coil-spring m7, said clutch member being provided with a pin 1n8,coacting with a slot m9 in said sleeve, and the inner face of said member being serrated in usual manner to coact with the clutch member m1", keyed i with an oriice in the head ny ol' the ribbonspool N. As will be seen, the forward movement of the carriage brings thc lever 1n* and pin mi into coawtion, therebyr through thc ratchet m turning the sleeve m, and' thereby the clutch member ml" andthe ribbon-spool N, carried by said clutch member. If desired, I may employ a pawl m, coacting with the ratchet m3, to preclude accidental (independent) movement of said ratchet. ()n the other side the upwardly-extending portion Z of the bracket L is provided with a bearing 0, through which extends a stub-shaft o, having the collar o adjacent to one end and the knurled operating-nut o2 at thev other. `Between the collar o vand the bearing O the stub-shaft is provided with a coil-spring 0'". Said stub-shaft o cacts with the other end n of the ribbon-spool N.

The brackets P P at the forward end 4of the carriage may be similar in construction to the brackets L, save that no provision need be here located for driving the ribbon-spool. To this end one of the stub-shafts p may be provided with a col/lar similar to the collar o and acoil-spring similar to the coil-spring o3, permitting the ribbon-spool N to be readily placed in position on the inward ends of said stub-shafts, the ribbon being fed from this spool to the spool N in the manner above described.

R designates a roll the ends whereof are journaled inthe brackets P P at the for .vard end of the carriage. 1' designates a similar roll, which may be convenientlygjournaled in a recess formed in the end member h of the chase or type-supporting frame. The rolls lr and r2 at the forward end of the carriage are similarly arranged, and all these rolls will be of a length somewhat greater than the width of the ink-ribbon I. Initially the ribbon is wound upon the spool N. It is then passed over the roll R, under the roll r, underthe roll r2, over the roll 1", and then made fast to the spool N. This brings it 'directly under the faces of the type set up in the chase or type-frame above described. At its rearward end the carriage may be provided with the operating-handle N2.

S designates a feed-board, here shown as provided 'with adjustable side and end guides S S2 S3. If desired, the forward end -of said feed-boardv may be provided with a hood s to protect the upper surface. of the sheet pile laid on said board from the inkribbon I.

The drawings illustrate the position of the several parts midway of the printing operation.l Starting at the beginning this operation is as follows: The carriage is rstpressed forward, whereupon the beveled surfaces Z2 are brought into Contact with the sheaves Z5,

los

or otherwise secured on the stub-shaft m. depressing the pressure-roller B. Next the f The inner face ofthe clutch member m1 is provided with a pin m, adapted to coact bosses Z3 are brought into contact with the upper arms e2 of thev locks E, tl1ereby throw- ISO ing said locks to engaging position and se the pile laid upon thev feedoard S may thenV be pressed forward, so that its forward end shall overlie the said pressure-roller. If now the carriage be moved rearward, the beveled surfaces p of the brackets at the forward end of the carriage will ride over the sheaves l5, and a momentlater the bosses p2, making contact with the upwardly-extending arms e'z of the lock E,vwill throw said lock to inoperative position, thereby leaving the pressure-roller free to sise after said beveled surfaces p have been moved out of contact with the sheaves Z5. If now the carriage be again moved rearwardly, the moment the beveled surfaces p and the iieaves Z5 are thrown out of coaction the pressure-roller will rise, thereby moving the sheet upward and into contact with the characters on the printingvsurfaces ofthe type held in the chase supported by the carriage and said chase, said sheet, and said pressure-roller moved forward in unison, the impression being printed upon said sheet meanwhile. At the conclusion of the printing operation the sheet is passed forward by the pressure-roller and may be received ina suitabletray, (not shown,) if desired. This forward (printing) movement of the carriagev also causes, through the coaction of the lever m4 and pin m5, the feeding of the ribbon from the spool N to the spool N so that for each printing movement of the carriage a fresh surface of the ink-ribbon I will be interposed between the type-faces and the impression-sheet.
