PRINTING-MACHINE.

Specification of Letters Patent.

Patented Dec. 5, 1911.

Application filed June 5, 1909. Serial No. 500,313.

following is a specification.

This invention relates to printing-machines for printing multiple copies of letters, circulars and the like.

The invention is directed to the provision of a printing-machine for office use, which is small and inexpensive to manufacture, which may be run by an unskilled operator,

and which is capable of printing in imitation of typewritten work.

More particularly, the invention is directed to the provision of a printing-machine having a pressure-roller arranged for movement in one direction in 'coaction with the type to effect the printing, and thenin the other direction on the opposite side of the type and the support therefor to return it to initial position in readiness for a repetition of the operation.

In accordance with my present invention, a platen is provided which is movable toward and away from the printing faces of the type, but the printing is not effected primarily by this movement of the platen; instead, the type are arranged for movement in the direction of their lengths and the pressure-roller is causedto engage the rear ends of the type and move the type so as to cause their printing faces to press against the impression-sheet with the desired pressure.

My invention 'is directed particularly to the provision of sheet--feeding devices and sheet-delivery devices in combination with a printing-machine of the type in which the pressure-roller is caused to move in one direction on one side of the type-form to effect the printing and in the other direction on the other side of the type-form to return to initial position. In accordance with this feature of the invention, sheetfeeding devices are arranged upon one side of the machine and feed the sheets successively from this side into the printing position. I have found that by so arranging the sheet-feeding devices greater convenience in operation is secured and the parts .of the machine may be more compactly arranged. The sheet-delivery devices are also arranged at one side of the machine, so that the sheets after they have been imprinted upon are fed from the printing position into a suitable tray at the side of the machine. Preferably both the sheet-feeding devices and sheet-delivery devices are arranged upon the same side of the machine, one directly below the other, this arrangement of the parts contributing to the compactness of the structure.

I have illustrated the preferred embodiment of my invention in the accompanying drawings, in which- Figure l is a plan view of the machine broken away and sectioned in part; Fig. 2 is a central vertical section of the same on line 2-2 of Fig. 3; Fig. 3 is a section of the machine on a plane transverse to that of the section of Fig. 2; Fig. at is a horizontal sectional elevation on line 4:-4: of Fig. 3; and Fig. 5 is an end view of the parts illustrated in Fig. 4.

Referring to these drawings, the machine consists of a base A on which are mounted side-frames A, A Extending between these side-frames are two shafts C, G, journaled in bearings formed in the side-frames and each carrying two sprocket-wheels 0, one adjacent to each of the side-frames. A chain 0 lies adjacent to each side-frame and runs upon two of the sprockets 0 upon the shafts C, C. Overlying each chain c is a cam 0 having a straight edge inter-v mediate its ends, this cam being adjustable vertically by means of nuts 0 on threaded studs secured to the cams, these nuts lying between offsets formed on the side-frames. Extending between the chains 0 and mounted for rotation in bearings formed in the chains, are one or more pressure-rollers D, D. The links of the chains 0 in'which are formed the bearings for the ends of the shafts of the rollers D, D, are enlarged somewhat, so that they coact with the faces coaction with the type, at a speed equal to that at which the roller rotates while in coaction with the type. Any suitable means may be provided for rotating the shafts C, C, and thus moving the rollers D, D, as, for instance, the crank 6Z2 shown in Fig. 1.

Extending between the side-frames of the machine are two bars E adapted to support the chase in which the type are mounted. This chase E is a rectangular frame having flanges, as shown in Fig. 2, for engaging the bars E. Extending across the chase E are a plurality of bars 0 forming channels in which the type 6 are inserted with their printing faces downward. These type are provided with shoulders intermediate their, ends, adapted to engage the bars 6 to hold the type in position. Overlying the rear upper ends of the type 6 is a pad 6 of yielding material, such as rubber, the upper surface of this pad lying above the upper surfaces of the chase E and bars 6. As the machine is adapted particularly for use in printing in imitation of typewritten work, an ink-ribbon F is shown as extending over the printing faces of the type, this ribbon having its ends wound upon spools f at opposite ends of the machine and rods or rollers f being provided extending between the side-frames of the machine to properly locate the ink-ribbon with reference to the printing faces of the type. If desired, means may be provided for feeding the ink-ribbon F in the direction of its length intermittently during the operation of the machine, as, for instance, by having a projection on one of the chains 0 actuate one of the spools f.

Directly below the type is a platen G .arranged for vertical movement toward and away from the type. Extending clownwardly from the under side of the platen G are pairs of bifurcated standards 9 which straddle shafts 9 extending between the side-frames of the machine and mounted for rotation in bearings formed therein. The

shafts 9 have cams g secured thereto, one adjacent to each standard 9, and each of these cams is adapted to coact with a roller 9 mounted for rotation upon the standard 9. At one side of the machine, the shafts g extend beyond the side-frame A and carry gears g which are connected together by an idler-gear g mounted for rotation upon a stubshaft projecting from the sideframe A. On the shaft O, outside the sideframe A, is a gear meshing with one of the gears 9 so that when the machine is operated by means of the handle (Z the shafts 9 will be rotated.

The sheets to be imprinted upon are fed into the machine from a feedingtable H at the side of the machine, through an elongated slot provided in the side-frame A and between the platen G and the ribbon F underlying the printing faces of the type. The mechanism for feeding the sheets into printing position may be constructed in various ways, but; prefer to employ for this purpose an apparatus constructed in accordance with Patent No. 929,292, dated July 27, 1909, this consisting of a pair of sheet-feeding rollers and one or more reciprocating grippers, the latter being adapted to grip a sheet and forward it until its edge is caught between the two sheet-feeding rollers, whereupon the latter forward the sheet to its proper position.

In the accompanying drawings, I have shown auxiliary frames 72, projecting outwardly from the side-frame A and having sheet-feeding rollers h and If mounted for rotation in bearings formed therein and geared together by means of intermeshing gears 7L secured upon the shafts thereof. These rollers are of sectional form, as shown in Fig. 1, so as to provide spaces between the adjacent sections thereof into which the reciprocating grippers may enter. The upper gripper I consists of a sheet-metal strip shaped as shown in Fig. 3 and having its ends bent downwardly and pivotally con nected to the ends of a bar 2' adapted to reciprocate beneath a sheet-metal extension 2" of the feed-table 8. To the bar '5 are secured the lower grippers J, these consisting of strips of sheet-metal bent as shown in Fig. 3, so as to provide in each a portion coacting with one of the fingers of the upper gripper I and having its upper surface lying in the plane of the upper surface of the feedboard. To the under side of each gripper J is pivoted a stop K having an upwardlyturned forward end projecting through a slot in the gripper J. At its rear end each stop K is bent to provide an inclined portion is adapted to engage a strip is when the stop is moved forwardly with the grippers, so as to turn the stop upon its pivot and thus cause its upwardly turned end to be drawn down below the upper surface of the gripper J.

Upon each of the downwardly turned ends of the upper gripper I, is a trunnion, which is received in a slot formed in the upper end of a lever L mounted upon a shaft pivoted in the auxiliary frame it. Springs Z are connected to the lower ends of these levers L and normally hold them in the positions in which they are shown in Fig. 3 with the grippers retracted. The shaft C is extended through its bearing in the side-frame A and carries a gear Z meshing with a gear Z upon a short shaft mounted in a bearing formed upon the side-frame A this shaft carrying a cam Z upon which rides a roller Z carried by a crank Z secured to the shaft Z upon which the levers -L are mounted. The plate 2" is extended beyond the sheet-feeding rollers 7L, k

through the slot provided in the side-frame A so as to guide the sheet properly into the printing position. In this position, the movement of the sheet is arrested by a plurality of stops 0 at the opposite side of the platen G.

After the sheet has been imprinted upon, it is delivered by moving it in the direction opposite to that in which it was moved by the sheet-feeding devices. This is effected, first, by moving the stops 0, which push the sheet edgewise before them until its opposite edge passes between two delivery rolls P. These rolls are geared together by means of intermeshing gears 39 and the shaft of one of the rollers carries a spiral gear p meshing with a similar gear upon the shaft C. Each of the stops 0 is pivotally connected to the lower end of a link 0, the upper end of which is pivotally connected to the support E for the chase E. A spring 0 is connected to the link 0 and tends to move the link in a direction to carry the stop O to the right in Fig. 3. A spring 0 connects the stop 0 and the link 0 and acts upon the stop so as to hold its end down upon the surface of the platen G. Each stop 0 is provided with a downwardly extending portion 0 on the end of which is a tooth coacting with a cam formed upon the side of a disk 0 secured to one of the shafts 9 The operation of the machine will now be described. By turning the handle d the shafts C, C, are rotated and the rollers D, D, are caused to move in one direction over the form of type and then return to initial position below the type-form. The shafts g are simultaneously rotated, and just as one of the pressure-rollers approaches the position for coaction with the type, the cams 9 upon the shafts g raise the platen G to such a position that the sheet of paper upon the platen is in contact with the ink-ribbon F directly overlying the printing faces of the type, this upward movement of the platen G preferably being such that the type e are raised slightly, these type being loose in the channels between the bars 6. Then as the operation of the machine continues, the pressure-roller engages the type e through the yielding pad 6 and presses these type down, so as to cause them to imprint upon the sheet through the ink-ribbon F. After the pressure-roller passes beyond the type, the cams 9 permit the platen G to move downwardly again to its initial position. .The feeding of the sheets to the printing position takes place while the platen G is in this downward position. The initial position of the sheet-feeding devices is that shown in Fig. 8, with the grippers separated, and the stops K having their forward ends raised. A sheet of paper is fed by hand between the grippers until its movement is arrested by its edge engaging the upwardly turned ends of the stops K. At the proper time with relation to the movement of the platen G and pressurerollers D, D, the cam Z turns the shaft Z so as to rock the levers L. These levers act first upon the upper gripper I through the trunnions connecting this gripper to the levers, by turning the gripper upon its pivotal connection to the bar 2' which carries the lower grippers J. This turning movement causes the upper gripper I to grip the sheet between it and the lower grippers J, whereupon further turning movement of the upper gripper is precluded, and the continued movement of levers L causes the upper and lower grippers to move forwardly until their ends enter the spaces between the sections of the sheet-feeding rollers h, 77/ The sections of these rollers then grip the edge of the sheet and the rotation of the rollers causes the sheet to be fed forwardly into printing position until its movement is arrested by the stops 0. As soon as the sheet-feeding rollers grip the sheet, the latter is released by the grippers, due to the fact that at this time the cam Z permits the levers L to be returned to initial position by springs Z. The first portion of this return movement causes the upper gripper I to be turned on its pivotal connection to the bar 2', so as to separate the two grippers. The sheet is then imprinted upon by raising the platen G as heretofore described, and when the platen is so raised the stoplevers 0 are turned on their pivots in a clockwise direction against the tensionof springs 0 After the sheet has been imprinted upon and the platen Gr lowered, the cams 0 move the stops 0 to the left in Fig. '3 and these stops push the printed sheet ahead of them until the opposite edge of the sheet is gripped between the deliveryrolls P, which deliver the sheet through the opening provided in the side-frame A as shown at the left in Fig. 8, into a suitable tray mounted to receive it.
