DUPLICATING-MACHINE.

Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed April 27, 1908. Serial No. 429,319.

To all whom it may concern:

Be it known that I, ALBERT H. BATES, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Duplicatin -Machines, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings.

The object of this invention is toprovide an eflicient machine for the rapid production of printed matter.

The invention is primarily adapted for reducing circulars or other matter in single sheets. When used for such circulars, I provide an inking ribbon through which the impression is made, whereby an appearance of typewriting is obtained.

The invention includes not only simple and efiicient means for giving the impression, but also for feeding the paper and for delivering the printed sheet.

The invention includes also means whereby the printed sheet is raised.from the form to allow its convenient delivery.

All these mechanisms are shown as associated in a simple unitary machine capable of carrying the individual sheets in blank and discharging them in printed form.

The drawings clearly illustrate a simple embodiment of my invention, wherein- Figure 1 is a side elevation of the machine, is a side elevation at right angles to Fig. 1, the left hand half of this view being shown in vertical central section; Fig. 3is a vertical section through the type bed in a plane parallel with Fig. 1; Fig. 4 is a vertical section on substantially the same plane as Fig. 3 but looking in the opposite direction; Fig. 5 is a plan of the machine, part of the ribbon being broken away; Fig. 6 is a perspective view of the marginal guide for the type and elastic track for the platen; Fig. 7 is a perspective view of the type adapted to be employed in the embodiment shown; Fig. 8 is a horizontal section substantially on the line 8-8 of Fig. 4 and-illustrating the operating mechanism of the ribbon feed; Fig. 9 is a detail of a member of the paper holder; Fig. 10 is a horizontal section substantially on the line 10-10 of Fig. 3 illustrating the delivery mechanism; Fig. 11 a fragmentary side elevation showing an arrangement wherein the bed is flat, enabling standard type, electro-types or other forms of printmg members to be used.

As shown in the drawings, 12 represents the side members of a suitable supporting stand or base braced by cross members 13 and carrying in its upper end the type bed 14. This bed may be flat or curved, as desired, and may carry individual type or elec rto-types or other printing members, as desired.

As shown in Figs. 1-5, the-type bed carries individual parallel rails 15 between which may be mounted individual type 16 grooved on their sides, as shown in Fig. 7. As shown in these figures, the type bed is an arc of a circle about a center 18 near the lower end of the base. Pivotally mounted at this oint in the base (shown in Fig. 2 by adjusta le eccentrics 19) is the shaft 18 to which are secured arms 20 connected at their upperends by a cross bar 21 and handle 22, which parts constitute an oscillatory frame. These arms carry a suitable roller platen 25 which is adapted to roll over and impress the type carried by the bed.

When the type is an arc of a circle and the arms are pivoted at the center of the are, as shown'in Figs. 1, 3 and 4, the presentation of the platen to the type is maintained without additional guides. When the type bed is flat, as shown in Fig. 11, the platen will be guided by axial extensions which carry rollers 26 operating beneath suitable rails 27 (adjustable by screws 24) and the arms 20 will be pivoted at their lower ends to a block 28 slidably mounted in vertical slots in the frame and given a central tendency by springs 29. This is illustrated in Fig. 11. In this case the printing surface 17 may consist of individual standard type or electro-types, for example.

From the above construction, it will be seen that if the type be suitably inked and paper he placed over it, the movement of the platen over the paper and inked type from one end of the form to the other will print the page. This movement the operator easily accomplishes by grasping the handle 22 and shoving or pulling it from one extreme position to the other.

To conveniently ink the type to enable it to produce an imitation of typwritten matter, I provid an inking ribbon. This is illustrated in Figs. 1, 3, and 5. The ribbon 30 passes over the form and onto two spools 31 between the side members 12 of the frame. On the end of each spool is a ratchet 32. Vertically slidable on the inner side of one of the frame plates is a plate 33 (Fig. 4) which carries a pivoted bar 34 on which are mounted pawls 35. The plate 33 has V- shaped notches 36 in which take pins 37 on a slidable bar 38. This bar is slidably held on the frame .plate and has near its ends pins 39 adapted to be engaged by one of the arms 20 as it comes into either extreme position.

The engagement of the arm 20 with a pin 39 shoves the bar 38 longitudinally and thereby raises the bar 34 and the pawls 35,. causing the pawl which is in engagement with the ratchet wheel 32 to rotate said wheel a portion of a rotation. The bar 34 is normally held with one of its pawls in engagement with one of the ratchets by reason of the springplunger 40 engaging in a notch in the arm 41 of the bar 34. When, however, the spool from which the ribbon is being wound becomes empty, the amount of force required to rotate the other spool is increased to a point where, when the plate 33 rises, instead of the engaged pawl rotating the engaged ratchet, the arm 41 slips beneath the plunger 40 and the other pawl comes into operation with the other ratchet; then for the next and succeeding movements; this other pawl operates its ratchet until thel ribbon is fed entirely in the other direction.- It will thus be seen that not only may I printf with an inking ribbon, butat the end of each printing operation after the impression is completed, the ribbon is fed a suitable distance to bring a fresh face to the platen, and the direction of feed is automatically changed when either spool becomes empty.

A sheet of paper may be laid on the form by hand in advance of the impression roller. It may also be removed by hand after the impression roller has traveled over it. It may likewise be placed. and removed mechanically. To enable the paper to be conveniently placed on the form mechanically, I arrange the paper to be carried by the oscillatory. frame itself which automatically feeds the pa or as the frame is shifted from one side to t e other. As shown in the drawings, the machine is double acting, that is, it rints a sheet on each stroke of the oscillatmg frame, whether backward or forward. In such machine I carry the aper by the oscillatin frame in two sup ies. This I accomplis as follows On t e oscillating frame are two pockets 50, each provided by an inner late 51 and an outer plate 52 and suitable edge guides 53 adjustably carried by the outer plate b operating throug means of thumb nuts 54 slots in that plate. The

carried by a rod 60 adjustably held to the arms 20 by being mounted in slots 61 therein and held by nuts 62. i

The springs 59 are adjustable so that their noses engage the paper in the pocket near the extreme edge of the foremost sheet. In this position, this foremost sheet has its lower edge engaging both the platen and the plate 57 near the rolled over edge 63 thereof. Now, if the oscillating frame is moved in the direction toward such pocket, the front sheet, being grasped by the platen and edge 63, is fed downwardly and released from the spring 59 at its upper end and grasped at its lower end by the roller and the type on the bed, wherefore, the paper lies on the type and the roller travels over it, impressing it. This movement is without effect on the paper in the other pocket for the platen is moving in the wrong direction to feed it. On the return movement of the frame, however, the front sheet in that pocket is grasped by the platen andthe edge 63 of the plate 57, and is fed between the platen and bed. As each sheet is drawn-down by the engagement of the platen and the edge 63, the other sheets of paper behind it are drawn down sufiiciently so that the spring 56 engages the next foremost sheet, which occupies the position of the sheet just fed. It should be noted that the spring 56 is a light one and operates simply to keep the block of paper together and pressed against the plate 51 and roller 25; that gravity, the in cline of the plate 57, and the downward pull of the roller 25 maintain the block of paper fanned out, while the adjustment of the plate 57 is such that but one sheet of paper passes between it and the roller 25. Furthermore, the platen has a soft rubber face whlch, of course, obtains a better grip on the first sheet of paper than the first sheet does on the succeeding sheet, though the spring 59 hearing directly on the first sheet tends to bind it to the succeeding sheet. The result is that the downward movement of the platen face pulls downward the whole block of fanned out sheets until the foremost one is released from the spring 59; then the foremost one alone is fed and, by being grasped between the roller 25 and the roll 63, is assed downwardly between the platen and orm, as stated The upward movement of theother side of the platen does not materially disturb the conditionof the block down in front of the platen and is impressed by it over the inking ribbon on the type form.

To insure the proper feeding of the paper as well as the rotation of the inking ribbon heretofore referred to, there is a slight idle movement of the platen beyond each end of the type form. To insure the platen rotating before it engages the form, I provide a pair of tracks which the platen constantly engages. These tracks are designated 70. They consist preferably of soft .rubber mounted on a suitable plate 71 which is adapted to form a marginal guide for'the type. This plate may have dove-tailed lugs 72 which fit into the grooves between the rails 15, as shown in Fi 6. To enable a convenient removal of t e paper after it is printed, I provide first, mechanism by which the end of the sheet is raised from the form, and second, mechanism for grasping such end and removing the sheet. If it is desired to omit this second mechanism and remove the sheet by hand, the same may be done, the first mechanism raising the sheet in a convenient position to allow'its removal either mechanically or by hand.

The means by which I raise the sheet consists of two elastic straps 80 which are anchored at higher points than theends of the form and extend across the bed adjacent to the edges of the form and beneath the platen. When the form is curved, these straps are normally tangent to it at its highest point, as shown in Figs. 1, 3 and 4. These straps are provided at their ends with hooks 81 by which they are secured to cross rods 82 which are adjustably held in brackets 83 carried by the frame. Fig. 4 shows one of the positions of rest of these elastic bands. They pass beneath the platen and lie adjacent to the tracks and in the recesses over the marginal strips7l. As the platen moves forward, the edge of the paper lies over these bands. During the move-- ment, the bands rise at the rear of the platen, raising the rear portion of the paper from the form so that its rear edge may be conveniently grasped, whereby it may be removed.

To allow the removal of the paper to be accomplished, mechanically, I provide between the frame members 12 the two arms 90 (Figs. 1, 3 and 5) which are mounted on cross shafts 91 which carry pinions 92 meshing with racks 93 on suitable bars 94 and 95 respectively and slidably guided on one of the frame plates.

Each of these bars carry pins 96 adapted to be engaged by one of the arms 20 on its extreme movement. As the arms are coming into this position, they shift the bars 94 or 95, as the case may be, moving the rack, rocking the pinion and thereby swinging the arm 90 from the idle position shown in the right hand portion of ,Fig. 3 up into the active position shown in the left hand portion. The upper end of the arm 90 is formed to extend over the sheet of paper held on the elastic straps 80. Pivoted to this arm is a. bar 97 which is adapted to pass beneath the paper and with the arm forms a pair of pinceis'adapted to grasp the sheet. I

The bar 97 is held to the arm with suflicient friction so that the arm remains in position relatively open or closed into which it has been forced. In the idle position, a in 98* holds the jaws open.- They remain 1n this position until they have passed around the edge of the paper. Then, as shown in the left hand portion of Fig. 3, a tailof the jaw 97 engages the eccentric 99 on the rod 82, forcing the jaws to close to grasp the paper. Now, with the return movement of the arm, which begins immediately with the return'movement of the oscillating frame, the sheet is drawn oil' of the form in advance of the new sheet to be laid thereon, and passes beneath the bar 82 and turns over with its printing side uppermost, and as the arm comes into final position it is releasedby the tail of the jaw engaging the rod'98. This return movement of the arm is caused by the spring 79 about its shaft 91. When released, the sheet falls into one of the baskets 100. The eccentric 99 may be adjusted by turning the rod 82 to cause the proper grasp of the paper, such adjustment being controlled by the set screws 85 locking the rod. To prevent the oscillating frame being inadvertently moved backward after it has started on a forward movement in either direction, I provide the stationary rack 101 and mount on the arm 20 a pawl 102 which trails over this rack from either direction but blocks backward movement.

It will be seen that I have provided a simple printing mechanism which is adapted to be operated by hand power, or other suitable means, and which will take up only a small amount of space but which may print very rapidly and may be self-feeding and self-delivering, if desired. While I have shown an inking ribbon, this may be omitted, if desired, and the form inked by a suitable hand roller or otherwise.
