TYPEWRITING MACHINE.

.Application filed July 27, 1925., Serial NoT 46,237.

This invention relates generally to typewriting machines, and is directed particularly to means for gaging and holding cards, or the like, against the printing-line of the platen for typing, especially near the bottom edges thereof.

rIhere is provided adjacent the front of the platen a chute for reception of a card or work-piece inserted'bottom edge downward, gages being provided for the side edges of the card, and card-grippingy means for firmly holding the card against displacement when brought to the printing-line for typing. The chute preferably includes a pair of adjustable wing-plates or tables carried by a suitable frame detachably mounted on the platen-frame; and a resilient second plate overlies each of the first-named' plates to provide a channel or chute for the card.- The plates preferably have cup-shaped depressions, the ones in the overlying plates projecting into the ones in the associated wing-plates or tables, thereby slightly indenting the card to effect a gripping action thereagainst and thus hold the same within the chute. druide-lingers extend downward from the plates to insure holding the lower edge of the card against the platen at the printing-line, and gages at the upper edge of the card determine the line-space positions for the lower portion. of the card. The upper edge gages include a vpair of laterally-adjustable gage-staffs, each carrying vertically-adjustable riders having 'a plurality of gage-stops, the upper edge of the card being successively positioned lagainst said gage-stops, to progressively line-space the card. Due to the factthat all line-spacing is eilfected by the gage-stops, the platen remains stationary, and is only turned when thought advisable to bring a. new striking surface beneath the type. The device is of extreme simplicity, being preferably stamped and bent to shape from thin gage-sheetmaterial, and is consequently inexpensive to manufacture. Y

One of the features ofthe invention is the 'provision of a card-chute having a cardreceiving channel of a width somewhat greater than the thickness of the card, thus permitting uninterrupted passage thereof, and interlocking depressions in the front and rear walls of the channel for indenting the card, thereby holding the same in typingposition within the chute. K

Another' feature of the invention is the provision of al card-chute including two separate sections carrying gages for the side edges of the card, the sections being adjustable through a wide range whereby', to accommodate a large variety ofcardsof different sizes.

Another feature of the invention is the provision of fingers extending downward from the plates at both the front and the back of the card, the rear finger supporting the card, to a pointclosely adjacent the surface of the platen, and the front finger pressing the lower portionrof the card against the platen at the printing-line.

Another feature of the invention lis the provision of upper edge gages for the card adjustable independently of the chute,` so

that the typist has a choice of disposing said gages behind the chute to thus enable the card to be grasped at the middle of its upper edge for removal and insertion, or disposing said gages inward toward the middle of the card, so as to enable the outer edges thereofv to'be readily grasped. The card may be fully inserted in the chute, and then all vadjustments made while the card isin such position.

A `fr irther feature of the invention relates to novel means for attachingthe overlying plates to the wing-plates or tables of the card-chute.

Otherfeatures and advantages will hereinafterA appear.

In the accompanying drawings, Figure l is a front elevation of the platen and the 'platen-frame of a typewriting machine, showing the invention applied thereto. y Figure 2 is a pe'rspectiveview of one portion of the card-chute, and means for mounting the same on the` platen-frame,some of the parts being separated for clearness of illustration.

Figure 3 isa vertical section on the line 3-3 of Figure l.

Figure 4- is a vertical section on the line t--t of Figure l.

Figure 5 is a sectionaldetail of means for fastening'together parts of the card-chute.v Referring particularly to Figure 1 of the drawings, represents a card or Work-piece inserted downward adjacent the front 'of a platen l1 to bring the bottom portion 12 of the card to the printing-line'. 13 of the platen, said platen being mounted by means of the usual platen-axle 14 in the side frames` 15 of a platen-carriage designated generally by the numeral 16. For guiding a card down to the printing-line, there is provided means including a pair of wing-shaped plates or tables 17 ,reach having a portion of the side edge thereof bent outward to form guides or gages 13 for the side edges of the card 10. The plates 17 also include side extentions 19, each having` its lowerl edge bent inward at 20 and then upward at 21 to engage around the lower edge 22iL of anin-l verted L-shaped bar 22supporting the plates 17 The plates 17 are offset at 17u' to provide a space between the back walls of said plates and the bar 22. The upper portion of each of the extensions 19 is bent over at 24 to overlie a ledge 23 of the bar 22, then downdown upon the ledge 23, the plates 17 are vsecured to the bar 22. f For holdinothe card 10 in-position lupon the plates 17, springclips or plates 29 are fastened to the extensions 19, and although any suitable fastening means may be employed, I prefer to utilize means such as best illustrated in Figure 5. It will be noted that each of the spring-clips 29 is offset at 30, thus establishing clearance above its associated plate 17, and providing fastening ears 31. rlhe metal of each of the extensions 19 is drawn out at 32 and perforated at 33 to provide a long thread fora screw 34, and an enlarged perforation 35 in each of the ears31 tits over the drawn out portion 33. A collar or washer 36 maintains the shoulder 37 of the screw 34 sufficiently above the outer limit of the drawn-out portion 33, to cause the pressure exerted by said screw to be transmitted directly to the ear 31, and thus hold the same in irm frictional engagement with the face' ofthe extension 19. Such fastening means permits the clips or plates 29 to be easily removed for instance when it is desired to slightly bend said clips foi-.either increasing or reducing the clearance thereof relative to the plates 17. kThe spring-clips 29 have their upper edges curved outward at 38 from the plates 17 to provide an easy entrance channel for vthe lower edge of the card 10. It will be observed that the offsets 30 for spacing the clips 29 from the plates 17 are positioned outward .from the vertical plane of the guides 18; thusthe side edges of the card 10 do not touch said offsets 30. Each of the plates 17 has a depending tongue 39 which extends downward to a point closely adjacent Vthe surface of the platen 11, and engages the rear face of the card, whereby to aid in supportingl the same in position for typing. The tongues 39 are especially advantageous when handling thin or flimsy cards. Each spring-clip 29 has a depending linger 40 overlying a tongue 39, said linger 40 extending to a point adjacent the printing-line, so as to securely hold the bottom edge 12 of the card 10 against the platen, to receive impressions of type 41. For securing the card against movement during the typing operation, there is provided gripping means in the form of depressions 42 in the plates 17 and corresponding complement-ary depressions 43 in the springclips or plates 29, the'depressions 42 and 43 being preferably cup-shaped. The depressions 43 extend somewhat Ywithin the depressions 42, so that when a card is inserted downward between the plates 17 and the spring-clips 29, said depressions bend or indent the card silliiciently to obtain a grip thereon and thus prevent the card from Vmoving out of posit-ion. It is to be understood that the plates 17 and the spring-clips 29' are isuiiiciently spaced from one another, so as not to interfere with the free movement of the card, and that the only holding action against the'card is exerted at the point where it is gripped by the interlocking depressions 42 and 43. Perforations 44 may be provided in each of the- depressions 42 and 43 for further aiding in gripping the card. For mounting the bar 22 on the machine, there is provided a pair of end plates or supports 45 extending over the out-turned extensions 46 of the frames 15, the plates 45 having perforations 47 for the reception of thumb-screws 48 which thread into the frames 15. The plates 45 include downwardly-bent tabs or walls 49. Each end of the bar 22 has a pair of horizontal slots 50. ScrewsI 51 pass through said slots 50 into threaded engagement with the walls 49, and it is obvious either one of the pairs of slots may be used in attaching the bar-22 to said walls 49. Thus the bar 22 and its associated parts are readily attachable to twov different types of machines by simply interchanging the screws 51 withveither one of the slots 50. For line-spacing the card 10, and at the same time supporting the same, there isprovided a pair of upstanding gage-staffs 52 mounted in sliding relation upon the bar 22 by means of clips 53 of a character similar to those used for attachment of the plates 17. rihe clips include an upper portion 54 bent over the ledge 23, then downward at 55 and then inward at 56. The lower portion of each clip is bent at 57 around the lower edge 22si of the bar 22m a manner similar tothe extensions 19 already described.V A screwthreaded plate 58 associated with each ot the clips 53 receives a. thumb-screw 59, thus providing` means for adjusting the gage-staffs 52 in any desired position along the bar 22, and it will be readily understood that said gage-staffs may be moved to adjusted position behind the tables 17. The statls 52 carry rideis G0; and set-screws 6l adjust the vertical position of the riders on said staii's 52, so as to accommodate ditlcrent depths otcards'. The riders (30 include an upperl gagepiece G2 and a lower gage-piece 63, against which the upper edge ot the card l() may be progressively positioned, whereby to linespace the bottom edge l2 of the card. For aiding the ingers el() in holding the card l0 against the platen, the machine preterably includes a wine-scale Gel having the upper edge thereof directed outward, as indicated at 65, from the platen ll, thus tacilitating passage of the bottom edge 12 of said card downward past tl'ie upper edge of the wing-scale. Spring-pressed rollers 6G are usually eniployed for pressing the wing-scale 6a toward-the platen. It it is desired to detach the card-holder troni the machine, it is only necessary to remove the thuiiib-screws 4S and then lift the whole device from the niachine, as a unit. It will also be understood that the device may be readily'fitted to another machine differing somewhat lroin that illustrated herein, and that the lower slot may be conveniently utilized for such purpose.

Variations may be resorted to within the scope ot' the invention, and portions ot the improvements may be used without others.
