- dress forms one at atime from the bottom oil a stack in a magazine, for movin each form to be printed laterally into printing position and back after the printing operation into feeding position, and for continuing the feeding movement to discharge position.

- Another object of the invention is to deposit and hold the paper in printin position during the printing movement of t e carriage, to give the printed sheet an initial discharge movement in the direction of the return movement of the carriage, and then to accelerate the discharge movement of the paper in a downward direction.

@ther objects of the invention are to provide simple and novel means for raising and lowering the address forms as they are moved into and out of printing position so as to clear the ribbon and toavoid obstructing or interfering with the travel of the carriage in either direction; for adjusting the platen to the work and to obtain clear and uniform printing impressions; to lower the platen into operative position at the end oi the return movement or the carriage and to raise the platen out of operative position at the end of the forward movement of the carriage; to raise the platen out of operative position at the beginning of the forward travel of the carriage ii a sheet is not in position to he fed to printing position; to feed the inlx ribbon at each operation of the machine; and to deliver the printed sheets in a pile in a drawer provided to reiceive them in the frame of the machine below the carriage. Y

Another important feature of the invention i988. floral Ho. $98,038.

is to rovide' newand novel selective means for se ecting predetermined address forms to be printed and to prevent address forms not selected for printing from being carried to ,printin position.

'And urther ob'ects of the invention are to provide means a apted to-be 0 rated by a printing device not to be printe for preventmg movement of the carriage, and to provide manually operated means for releasing the carriage and for removing the address form which was not selected for printin In the accompanying drawings ifiustrating a selected embodiment of the invention, the views are as follows: V

ileferring to the drawings, main frame having depen in side bars 2, 2 and a carriage 3 having a lower part 4 and an upper part or housing 5, is mounted for reciprocal movement on the frame. Ball bearings 6, 6 Fig. 19 of the type disclosed in 00- ending application Serial No. 243 868, filed December 31, 1927, are interposed between the side bars and the frame to facilitate the movement of the carriage. It is desirable to provide locking means which will prevent any reverse movement of the carriage before it has completed its full stroke, and to this end I provide a roller 7, Figs. 4 and 5, which travels on the edge 8 of 1 designates a the main frame, Fig. 19, and cooperates with the cam faces 9, 9 on a block 10 inserted in a recess 11 in the carriage, and also with spaced recesses 12, 12 in the edge 8 of the main frame. The roller 7 is confined between the edge 8 of the frame and the cam faces 9, 9 and the walls of the recess 11 so that it will always be retained in place between the carria e and the frame. The reoesses are provi ed at the end of the travel of the carriage in each direction to permit reverse movement of the carriage. While the carriage is traveling between the ends of its movements in either direction the roller is riding on the edge 8 of the frame and is car-' ried along by the carriage the cam faces 9, 9are dispoud to wedge the roller between catory movement of the carriage t g longitudinal the carriage and the frame at any position of the roller between the recesses 12, 12 and this wedging will lock the carriage so that it cannot be moved in reverse during its forward movement or during its return movement.

A cross shaft 13 is mounted in the lower part 4 of the carriage and a roller 14 mounted on said shaft engages a groove 15 in the cam lever 16, which is pivoted to the frame at 17, Figs. 15 and 16. During reciprocation of the carriage the-roller 14 engages the cam lever groove 15 and reciprocates the cam 1ever 16 transversely. An upstandin finger or pin 18 is fixed to the forward on of the cam lever and it engages a slot 19, Fig. 15, in the sliding carrier plate 20 so that during reciprocation of the carriage the cam lever 16 will cause transverse reciprocation of this carrier plate.

A frame 21, Fig. 3 for the feeding mechanism is secured to the main frame and supports the magazine 22 which carries a stack of printing devices 23 bearin the address or other forms, Figs. 5 to 10 inc usive. A feed bar 24, more clearly shown in Fig. 9, is slidably mounted on the feed frame 21, and a feed bar handle 25 carr ing a lug 26 is pivotally mounted on the en of the feed bar as clearly shown in Fig. 9. A lug 27, Fig. 15 projects outwardly from the carriage and engages the lug 26 on the handle so that during1 reciproe lug 27 will move the feed bar 24 rearwardly. tape 28, Fig. 6 connected to the feed bar and to the spring barrel 29 returns the feed bar to normal or initial position during forward movement of the carriage. A spring bumper 30 is arranged at the end of the feed frame 21 to limit the return movement of the feed bar 24, Fig. 6. A pair of arms 31, Fi 9, are

connected to the forward end of the eed bar 24 and extend rearwardly to the magazine 22. These arms are adapted to enga e the front edge of the lowermost printing evice 23 in the magazine and ush said device from beneath the stack and to a osition opposite its printing osition. A p ate 32, 15, is fixed to t e carrier plate 20 and a printing device carrier block 33 is detachably mounted thereon. A sliding bed 34, Figs. 15 and 24, is provided with a lurality of recesses 35, Fig. 24, which receive the ins 36 fixed in the main frame. The sli ing bed 34 is stepped up at 38 to provide a shoulder 39 against which the plate 32 strikes during inward movement of the carrier plate 20. As plate 20 continues to move to the left, Fig. 15, plate 32 will engage shoulder 39 and carry the bed 34 with it and c ause said bed to ride up on the pins 36 and slide to printing position, Fig. 24 and supporting the carrier and bed block 33 in proper relation to the bed 37 and the address printing device 23 in printing position and in proper relative position to the body form 37. An arm 40, Fig. 15, lined to the bed 34 carries an upstanding'pin 41, which is adapted to be received in an open ture. 42 arranged in the bar 43 fixed to the plate 20 to properly register the bed 34 and to return it to normal position during return movement of the carrier plate 20. A suitable bumper or stop 44 is fixed to the main frame I to the feed bar 24 to limit the return movement of the sliding.

bed 34. The carrier plate 20 is supported by a plurality of rollers 45 fixed to a part of the main frame Figs. 14, 15. A yoke 46 fixed dogs 49 are fixed on the shaft 48 to engage the forward edge of a printing device 23in the position to which the arins 31 push the bot tom printing device 'inj'the stacks A slide bar'50, having slhts 51, is slidably mounted on screws 52 which are screwed to -the sup' porting frame 21 for the. 'feed mechanism.

The'bar 56 is thus capable of longitudinal the feed her 24,tothe.left'in Fig. 9.; Upon reaching the end of said movement or travel of the feed bar 24, the pin 54 will ride under the flexible finger 57, which is hired to the bar'55 and which springs down into the path of the pin 54 as said pin passes beyond the finger. Upon-return movement, to the right, Fig. 9, of the feed bar 24, the in 54 will ride up on the flexible finger 57 an turn the shaft 48 to restore the dogs 49 to their'raised posi tion and to clear any printing device in pushed position, Fig. 26. A finger 58 is fastened to the yoke 46 and engages one of the dogs 49 to limit their upward movement Fig. 6. A bar 59 is fixed to the yoke 46 and alternately engages at the ends of its stroke the pins 60, 60 which are fixed to the slide bar Fig. 9. During reciprocatory movement oi the feed bar 24 the bar 59 alternately strikes causing longitudinal and the pins 60, vertical movement the guide slots5l. the slide bar and to a part of the feed frame, acts to yieldingly hold the slide bar 50 in normal position Fig. 9, in relation to guide slots 51 and screws 52. The movement or the slide bar 56 is for the purpose of lowering and raising the selector bar yoke 62.;

This yoke 62 is pivotally mounted on the stud 63 fixed to the feed frame 21 and carries the selector pin bar 64 Fig. 8. A pin 65 is fixed to one arm of the yoke 62 and operates in a slot 66 in the slide bar 50, and when said or the slide bar 50 due to slide bar movestoward the left in Fig. 9 said and connected to the pusher arms 31 by the rods 47, has a rockershaft 48 mounted therein Figs. 9, 15; A pair of feed A spring 61, fastened to the yoke 62, bears to move the rod .67 during. vertical movement of the selector pin bar" 64. A bell crank 70 pivoted to the feed frame at pin moves into the clearance provided in said slot and the spring 62 is free to move the yoke 62 downwardly and therefore move the selector bar into a position to perform a selection. When the slide bar 50 movesin the opposite direction the pin 65 engages the lower formed edge of the slot 66 and the pin 65 and therefore the yoke 62 and bar 64 are positively forced upwardly."

A red 67, Figs. 5 and 6, pivotally mounted thereof which engages a slot 72 in the rod 67 so that during movement of the selector pin bar and the rod 67, the end 73 of the bell crank will move laterally, Fig. 9-A. The end 73 of the bell crank 70 is slotted at. 74 to receive the pin 75 on the transverse" bolt 76 which is slidably mounted in a channel shaped member 77 fastened to the bottom of the feed frame at 78, F igs. 6, 8 and 9. When 75 on the stud 63 has a block 68 formed thereon against which the set screw 69, thlreaded in so 70' is provided with a pin 71 at one end the selector pin bar moves vertically, the rod 7 67 operates the bell crank 70 by means of the slot 72 and the pin 71.to slide the bolt 76 transversely in the member 77. When the yoke 62 swings down, the bolt 76 will pro ect inwardly in the path of the carriage and when the selector pin barhas reached the.

limit of its downward travel the bolt 76 will recede slightly to permit th carriage to pass. The inward and outward ovement of this bolt is operated by the pin 71 operating in the slot 72. When the pin is in elther the upper f or lower strai ht portion of the slot .72 the bolt 7 6 is free om engagement with the carriage but when the pin 71 is in the curved intermediate portion 7 "of the slot the bolt 76 engages a part of the carriage and prevents movement thereof. A suitable spring 79 connects the rod 67 with the yoke 62, Fig.

6, to return the rod to normal or initial pos1- tion after it has been operated by the yoke 62. a

A packer 80 is pivoted to the feed frame and.

as an arm 81. projecting therefrom which extends through an opening 82 in the side of the teed frame Figs. 5, 8. A beveled lug 83 is fixed to the feed bar 24 so that during forward movement of the carriage the lug 83 will strike the arm 8land move the packer forwardly, to the right, Fig. 8 and pack the printing devices 23 against the slid- 3 able weight 84 in the compartment 85 beneath the feed frame- A spring 80 is connected to the packer 80 to return it to initial position. A chute 66 is suitably connected to the feed frame, Figs. 5 and 8, through which the printing devices pass to the bottom of the compartment 85 as indicated by the directional arrow in Fig. 5.

In practice a stack of printing devices is arranged in the magazine 22 and the car-
