FEED MECHANISM FOR TYPE-WRITERS.

To all whom it may concern.

15c 1t known that we, J ASPER H. S'rxmunnn and LEWIS D. STOCKING, citizens of the.

to a typewriting machine whenever the platen is rotated and discharge the same when the writing has been applied thereto and to provide the device with various new and useful features hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of a device embodying our invention as it appears when in position for use; Fig. 2 is a side elevation with the driving mechanism and one side of the frame removed; Fig. 3 a side elevation with portions removed to show the construction, and with the upper part detached and raised; Fig. 4 a side elevation of the side opposite to Fig. 1; Fig. 5 a front elevation of the device; Fig. 6 a plan view of a portion at the rear of the main frame; Fig. 7 a rear elevation of the upper part of the machine; Fig. 8 an enlarged detail partially in section of theieed roller and gate; and Fig. 9 an enlarged View partially in section of one end of the platen and a part of the main frame; and Fig. 10 a detail showing a modification to adapt the device to various sizes of platen shafts of-typewriters.

Like numbers refer to like parts in all of the figures.

1 represents a portion of a typewriting machine.

2 is the main frame of our device.

3 the upper frame of the same detachably mounted on the main frame by means of a slot 3- in the upper frame to engage the shaft 49 and secured in place by a detachable hook 3", as shown in Fig. 3. The rear of the upper frame is supported by props 7 extending upward from the cross bar 9 on Specification of Letters Patent.

the main frame. By releasing the hook 3" the upper frame may be lifted off for filling the machine with cards or other material to be written on as shown in Fig. 2.

4t the shaft of the platen 4 of the typewritmg machine on which shaft is mounted the main frame 2 the rear of said frame being supported by a screw 5 resting on the carriage 6 of the typewriting machine, whereby the whole of the device is supported on the said carriage and carried to and fro thereby. At the rear of the main frame is pivoted at the axis of the shaft 51 a rear extension comprising rearwardly extended arms 8 vertically ad ustable at the rear, and held adjusted by means of a slotted segment 30 on the main frame and a binding screw 31 therein whereby the arms 8 can be inclined more or less, to properly cause the cards to feed.

9 and 9 are cross bars of the main frame slotted at one end whereby the frame may be adjusted for width to fit various sizes of typewriters, being held in adjustment by binding screws 9". The bar 9 connects the arms 8 and the bar 9 connects upwardly extended curved arms 8 on the said arms 8. Mounted on the bar 9 are side guides 11 and a middle strip 10 is supported on the bar 9, on which strip is mounted a rear guide 11 adjustable to fit various sizes of cards.

12 is a feed roller about the axis of which the arms 8 are adjust-able, above the feed roller are spring pressed rollers 13 supported by the bar 9.

14 is an adjustable gate against which the cards are held by gravity and the inclined rear guide 11, this gate is adjusted by a screw 16 with its lower edge spaced apart from the rollers 12 to permit but one card at a time topass between the same and the said roller. This gate is held adjusted by a screw 15. v

17 is a second feed roller above the platen bet-ween the rear of which and rollers 35 the cards then pass and are delivered and guided by the guide plate 18 of the typewriting machine into proper place upon the platen of the said machine where they can be written upon in the usual way. They then pass upward directed by the guide arms 3-1 to the forward side of the rollers 17 between which and spring pressed rollers 19 they are carried upward and in succession along the upper frame by means of a series of

rollers

20, 22 and 24 each provided with spring pressed

rollers

21, 23 and 25, the card being discharged over the rear rollers 24 upon downwardly inclined guides 29 being discharged from the rear of the machine by gravity. The series of

rollers

19, 21, 23 and 25 are supported in a yieldable frame consisting of a flexible loop 26 attached to the frame 3 and supporting bars 27 on which bars are mounted spring arms 28.

32 are the knobs by which the platen 4 of the typewriting machine is rotated in the usual manner. provided with a gear 33 which meshes with an idler 36 which in turn engages a gear 37 which gear through

idlers

38 and 39 retates a gear 40. The gear 37 is mounted on a shaft 49, and the gear 40 on the shaft 51. The shaft 49 also carries a pinion 41 which engages with an idler 42 which idler drives a gear 43 on the shaft 52 on which shaft are mounted the rollers 20. Two

other shafts

53 and 54 carry the

rollers

23 and 24 respectively and these latter shafts are driven in the same direction as the shaft 52 by means of

sprokcet wheels

44, 45 and 46 engaged by

chains

47 and 48. On the shaft 50 are mounted the rollers 35 and on the shaft 51 is fixed the rollers 12. One side of the main frame is adjustable longitudinally of the

shafts

49 and 50 and the

bars

9 and 9" to adapt the device to fit typewriting machines of various widths.

Fig. 10 shows a device adapted to apply to shafts of various sizes in which the wheel 33 is separate from the knob 32' and provided with a hub having tapered keys 33", adjusted by the knob 32 having a hub or bars screw threaded upon the hub of the wheel 33* to engage and force the keys 33 inward to clamp the shaft 4.

It will be noted that the side guides 11 are adjustable on the bar 9 (see Fig. 6) and the loop 26 laterally extended beyond the frame 3, also that the driving mechanism of this upper series of rollers is all below the plane traversed by the cards.

Thus various sizes of cards or envelops will pass through the machine by merely adjusting the

guides

11 and 11 to fit the same.
