Application filed January 20, 19M. Serial No. 813,163.

To all whom it may concern:

Be it known that I. Gnovnn F. CovenonLL, e. citizen of the United States, residing in Council Bluli's, in the county of lottewattamie and State of Iowa, have invented cer-- tain 11B and useful improvements in Type Writing lyiacliines of which the followieg is e specification.

This invention relates to a. feeding device for typewriting machines, whereby envelops cerds and paper sheets can be sue-oessively fed to the platen roll of the machine by merely turning such roll.

The invention has for one of its objects to improve. and simplify the construction and operation of devices of this character so es to be comparatively simple and inex pensive to nienofzicture, reliable end eificient in use, and readily manipulated and adapted for use on any standard typewriter. Y

Another object of the invention is the different sizes of envelope, cords and paper. Still another object oi the invention is the employment of an improved 0 crating connection between the platen vol of the typewriter andthe feed rollers of the ettachment.

A further feature of the invention is the provision of adjustable guides to receive the envelop or sheet, as it emerges from the platen, to guide it clear of the magazine.

With these objects in view, and others as will appear as the description prooeeds, the invention comprises the various novel features of construction and arrangement of .perts which will be more fully described hereinafter and set forth with p. "ticularity' in the claims appended hereto.

In the accompanying drawings, Figure 1 I is a front view of this invention detached from the typewriter. Fig. 2 is a rear view of the same, showing the feed rolls and their driving mechanism. sectional elevation of the some mounted over a platen frame, which is shown diagrammatically. Fig. 4 is a perspective view of oneof the guide 6 gas. Fig. 5 is a perspective View of 1' sections of the ;:-:.per or envelop holder.

Fig. '6 is a fragmentary perspective view of one end of the bottom section of the holder. Fig. 7 is a fragmentary perspective View of Fig. 3 is a. side.

of the adjustable end the envelop regulator plate. Fig. Sisa. similar view of the paper regulator plate.

Similar reference characters are employed to designate corresponding parts throughout the Several views.

Referring to the drawing, A designates the bottom section of the rack or holder for the envelope, paper or cards, and'mounted on this bottom section are adjustable end sections B, whereby tlie'rack can be widened 10.1" shortened according to the size of the paper, envelope or cords to be typewritten. The bottom section A is composed of two guide plates or bars 1 and 2 which are spaced apart to provide a guide passage 3,

through which the paper or envelops are fed, and seemed to the ends of these plates or bars are brackets e, serving to secure the attachment to-the carriages? of the typewriter, these brackets being of any desired shape or design'=to suit different makes of tybewritingmachines. The front guide plate l-is bent io'i werdly into a. horizontally attending plate portion 5, which has its ont edgejbent. upwardly into a. flange 6 extending full length of the bottom section, thereby stifiening the structure and forming a shallow chamber *8 with the receiving regulator plate '8. The rear plate 2- pro ject's above. the horizontal plete portion 5 to serve to holdthe rearmost sheet of paper,

' envelop or the like in line with the'feed or 10 engage the end edges of the sheets or euveloos to hold them all in even pile and on eac member 10 is an inwardly extending finger l3 spaced from the portions 11 to hold the sheets or enveloys in upright position and preventing them from tilting forwardly. On the bottom of eaeh member 10 is e foot extension le which rests on the horizontal plate '5 of the bottomseetion A. Each extension 11,.as shown inl ig. 5, has an inverted U-shaped lug that has a slid ing engagement with the flange 6 of the bottom section of the rack or holder and the outer frontportionot' the lug has? a depending linger piece 16, whereby the end the end sections are securely held on the 'bottom section, although free to slide in wardly or outwardly to change the width of the holderor rack, 1 I

The envelope orsheets are fed from the raclrhy means of spaced rubber faced rollersfil mounted on a rotary shaft 22 disposed behind the bottom section of the rack and journaledin'hearings fi secured to the ends of the hot-tom section A and the fore ward portions of the rollers extend through openings in the back plate 52 of the hottom section. 9n one end of the shaft supported a framed?) composed oispaced platesbetween which are mounted gear wheels, whereby motion can be transmitted to the shaft 22 by the platen roll 22. A. large year wheel. 26 is'journaled in the frame and has a hollow hub 27 through which the platen shaft :27 extends, the hub being rigidly secured to the shaft in any suitable manner. The shaft passes through the frame and l12lS=Zl pinion :28, which is' driven from the gear 26, by means of intermediate gears'29. It will be obvious-that the turning of the platen will result in the automatic. feed of one sheet or envelop at a time vfrom the attachment to the platen. Cooperating with each feed roller 21 is gripping roller 31 mounted on the front bar or plate 1 of thebotton'i section in frictional engagement with its companion-feed roller 21. The frictionrollers 31 are arranged under the horizontal plate portion 5 ofthe bottom section 'A and they engage their re spective feed rollers through openings 32 (Fig. 6), in the bar or plate 1. lrlounted on the bottom section of the holder or rack is a regulator plate 33,.which has its rear edge 34' disposed adjacent the feed rollers, where they project through the openings;

andthis regulator plate is adjustable toward forfrom the rollers according ness of theenvelop,xpaper.or card, so that butonesheet, envelop or card dill feed at! 'a time. This plate 33 is disposed over the to the. thickforward horizontal projecting portion f the bottom section and has-itsior rard edge bent downwardly into a longitudinal flange- 'ing feedand friction rollers of 35, which is disposed in front of the flange 6 and is secured to the same by bolts 36. On these bolts are resilient washers 37 or equivalent devices, so that by tightening or loosening the nuts of the bolts the rear edge of the regulator plate can be adjusted with respect to the feed rollers. -The top surface. of the regulator plate shown in F i'g. 7, is inclined downwardly and rearwardly so thatthe lower edges of envelops' or sheets will. rest on this inclined portion of the pile and thereby the pile will be formed into a comb. The edge 34 of theregulator plate is disposed approximately in a hori- Ii'ontal plane passing through the axis of the feed rollers and immediately under this edge 3- are located the friction rollers 31 .so that the said friction rollers will take hold of the rear-most card, envelo a, or sheet as the latter is moved downwardly off the. regulator plate by the feed rollers.

In practice, it -"hasgoeen found that the regulator plate for envelope should be constructed as shown in Fig. '1, with the marginal portion 34 slightly convexed at its top surface, while the regulator plate, (Fig. 8), for paper sheets should have itsrear marginal portionslightly-"concave so as tobe disposed more nearly in a radial position with respect to thefeed rollers. To insure the proper feeding in of the workieces, an arcuate wire 38 is attached at eac end to the bolts 36, and bent rearwardly against said work-pieces, to constantly urge the latteronward to-the bite of the feed rolls 21 and 31; As the top edge of the work-piece moves away from the platen, after receiving successive lines of impressions from type 39, I

its side edges are engaged by fingers 40 and guided clear. of the magazine through channels 41, formed by heading back portions 42 of the I said fingers, as shown in Fig: {1. These fingers are shiftably supported at 4:3 or? the flange 6 of the front guide plate 1,

"and may'he adjusted for variations in the width ol'th, work-pieces.

. In operation, theend sections are adjusted inwardly or outwardly according to the width of the envelope, cards of sheets to be typewritten and a proper regulator plate is placed on the bottom section and adjusted hack and forth into operative relation with the feed rollers. A pile of envelops, cards, 0:: sheets, as the case may be, is placed in the holder or rack in an approximately vertical position, the ends of the pile being held by the end sections B, while the bottom of the pile rests-on the'regulator plate with the rearmost envelop, card, or sheet The. platen the co-actthe attachmentto removethe' rearmost envelop, cardor shee tand bring it into cooperative relatioi'r. with the feeding mechanism of the" in contact with the feed rollers. rollislnow turned so as to cause claim:
