PRINTING MECHANISM.

Specification of Letters Patent.

' Patented May 16, 1916.

Substitute for application Serial No. 289,785,111 December 1, 1905. Renewed March 23, 1909, Serial No. 485,232. This application filed August 11, 1915. Serial No. 45,041.

To all whom it may concern Be it known that I, \VALTER IVRIGHT, a citizen of the United States, residing at New York city, in the county and State of New York, have invented certain new an useful Improvements in Printing Mechanism, of which the following is a specification.

This invention relates to improvements in printing mechanism, and especially to that class of mechanism used for printing manifold copies resembling typewritten matter, the object of the invention being to provide an apparatus of this character which will print such copies with With this main object in view, the principal improvements are to provide means for feeding the sheets of paper on to the bed in both directions of reciprocation thereof.

In the accompanying drawing Figure 1 is a longitudinal section of the apparatus, certain parts being shown in side elevation; Fig. 2 is a side view of the apparatus; Fig. 3 is a broken plan view of the lower portion of the apparatus; Fig. 1 is a detail sectional view of the side of a paper box; Fig. 5 is a broken plan view of the end of a guide roller; Fig. 6 is a plan view of the whole apparatus; Fig. 7 is a plan view of the feed box being removed; Fig. 8 is a broken end elevation of the same; Fig. 9 is a sectional view of one of the boxes for the cylinder; Fig. 10 is a plan view of the end of one of the ribbon feed shafts; and Fig. 11 is a longitudinal section of the same.

Referring to the drawings, 1 represents a frame on which the apparatus is mounted, the bed 2 moving on ball bearings 3 in grooves l in the top of the frame. In said bed 2 is contained the chase 5 with the type surface 6. To reciprocate said bed there is provided a transverse shaft 7 rotated by the a usual crank handle. not shown. which shaft 7 has secured thereon. adjacent to each side of the frame, a wheel 8 having two segment gears 9, ll), of which the segment gear 9 is substantially a semi-cin-ular gear and of smaller radius while thrsegment gear 10 is slightly less than a semi-circular gear but of larger radius. The gear 10 meshes direct with a rack ll secured underneath the corresponding side of the bed, while the gear 9 meshes with a pinion 12 mounted upon a transverse shaft said pinion itself great rapidity.

engaging said rack. IVith this mechanism there is produced from the continuous rotary motion of the shaft a reciprocating motion of thebed, for, as the end of the segment car 10 passes. the vertical plane througi the shaft 7 and travels out of mesh with the rack 11, the semi-circular gear 9 travels into mesh with the pinion 12 causing said pinion to revolve in the opposite direction to that in which it had been just revolving, and impartin a backward movement to the rack 11. hen the rear end of the semi-circular gear 9 passes away from the pinion 12, the advancing end of the segment gear 10 comes into mesh with the rack 11 causing it and the pinion 12 to travel in the opposite direction. This contrivance enables the apparatus to be operated at great speed.

For the purpose of obtaining rapidity of printing with this class of devices, there is provided mechanism for feeding and printing sheets during each movement of reciprocation of the bed. For this purpose on each side of the center of the machine is a feed frame 14 extending obliquely upward and outward from a point near the center, in which frame is placed a box '15 having its ends 17 oblique to the back 18, said box containing t e pile of sheets to be delivered from that side to the printing mechanism. The sides of the frame 14 have lips or flanges 19 bent inward over the edge of the box to hold the sheets in the box. Vithin the box is a false bottom 20 which has pins 21 extending through slots 22 in the sides of the box and is drawn forward to the front of the frame by springs 23. This construction insures that the uppermost sheet of the pile is always pressed against a roller 24 carried upon a shaft 25, the end of said shaft having a small gear 26 meshing with an internal segment rack 27, carried u on the end of a lever 28 pivoted on the eed frame 14 at 29 and having a downwardly extending finger 30. Said racks for the two feed frames are on opposite sides of the machine, and the corresponding downwardly extending finger 30 is adapted to be engaged by a post 31 on the same side of the machine. Supposing that the bed in Fig. 1 is moving from left to ri ht, said post 31 impinges upon the finger 0 and causes the lever 28to oscillate, and thereby to impart a hit-hnni'led rotary motion to the feed roller 2+ on the. right 111119115 the undernide of m d l'eed roller, which is in 1,-oni'11vt with the uppermost blitkt o1 paper, to move upward, 1.1111! drawing the hive; edge oi Sillti heet 11hove the upper edge o'i' :1 rim or lip 3Z5 hent upward from the hottoin ot' the 512 1111: ll. ,ts the linger thus rocked by the 111111 1110111: 111 the 1.11%. it is mused to ee11- tiiet with :1 lfflflhdii'hllff extending p1i11; 3%, and then to (11ll1})l'(-i :hlltl wring. no that, 11:1 ;-,oo11 115 the. post eavzipes from the finger, the eprine; thrmvs the finger inn-it nliglltl t' but sul hrientl v fur to he engaged h \f the post upon its return niovenlent.
