Specification of Letters Patent.

Patented May 2d, 1912?.

Application filed September 18, 1911. Serial No. 649,852.

To all whom it may concern Be it known that I, SIDNEY VwJ ONES, a citizen of the United States, residing at Tucker, in the county of Utah, State of Utah, have invented certain new and useful Improvements in Automatic Type-VVriter Feeds; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 7

This invention relates to automatic'paper feeds for typewriters.

An object of the present invention is to provide a rack which may be attached to an ordinary typewriter and will support telegraph blanks and the like, a'pressure plate being provided for-holding the sheets in frictionalengagement with .the feed rollers.

A'further' object ofthe invention is to provide a novel spring controlled pin which pierces the sheets and holds the same together, the sheets being successively detached from the pin by the feed rollers.

With the above objects in view the invention consists in'certain novel details of construction and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claims.

In the accompanying drawings forming part of this specification :-ligure l is a side elevation of a typewriter equipped with a paper feed embodying my improvements. Fig. 2 is a plan view of the paper feed applied to a typewriter." Fig. 3 is a rear ele; vationof the paper feed applied to a type- "writer with the lower portion of the typemountings.

Fig. 6 is a fragmentary detail perspective view of the pressure. plate and its Fig. 7 is a side elevation of a pneumatic feed roller with parts broken away. Fig. 8 is a detail perspective View of the needle bracket. 1

Referring now to the drawings in which like characters of reference designate similar parts, 10' designates the frame, 11 the platen, and 12 thespacing bar of an 'ordinary typewriter-i; Attached preferably to the spacing bar nean'eachend thereof are brackets 13 and 14: which serve" as supports for the paper rack. These brackets may be of any preferred form and may be attached in any desired manner to the spacing bar orother suitable part of the carriage, and in the present instance, the bracket 13 is'shown substantially U-shape in outline and having one leg bolted as shown at 15 to the spacing bar, and its opposite leg bolted as shown at 16 to the underneath face of the paper rack. The mating bracket 14 is substantially U- shape in outline and has its bightbolted as shown at 16 to the spacing bar while its terminals are bolted to the underneath face of the paperrack,

The paper rack comprises spaced longitudinal angle iron side bars 17, the upper ends of which are connected by an angle iron top bar 18, and the lower ends of which are connected by a plate 19 the lowermost edge 20 of which extends beyond the side bars and is curved in outline to conform to the curvature of the typewriter paper support. The sidebars are spaced apartsufiiciently to permit of the insertion therebetween of telegraph blanks or the like, and for supporting various sizes of blahks, a pair of substantially l -shaped standards 21 are secured to the side bars, and are connected by a rod 22., to which are attached the eyes 28 of angle iron hangers 24, the eyes being adjust ably secured to the rod by means of set screws 25. The angle iron hangers are moved into engagement with the edges of a bundle of blanks and perform the dual function of supporting the blanks and forming guides to direct the sliding movement of the blanks downwardly to the platen. To accommodate blanks of different lengths, the top bar 18 is adjustably secured to the side bars of the paper rack, the preferred manner of attaining this end being to form the bar with upstanding ends 26 which bear along the inner faces of the side bars and are equipped with inverted U-shape straps 27 which straddle the side bars, set screws 28 beirig threaded through suitable openings formed in the outer legs of the straps,

and being advanced into engagement with.

For. detachably securing all of the sheets together, a bar 29 is terminally secured to the before mentioned upstanding ends 26,

and is preferably square in cross section.

An angle iron clip 30 is 'provided on one leg with an eye 31 which loosely encircles the bar and is equipped with aset screw 32 for securing the clip in any desired posltlon longitudinally of the bar. The mating leg of the clip is formed in its top face with agroove 33 which slidingly receives the lowerscrew 35 being inserted through a slot in the bracket leg and a suitable registering opening in the clip leg to permit of adjustment' of the bracket longitudinally of the clip leg. Alined square openings 36 are formed in the bracket legs and slidingly receive a pin 37, this pin being provided with a counterbore at its lower end for the reception of a needle 38, the latter being detachably secured in the counterbore by means of a set screw 39. A thumb nut 40 is formed on the upper end of the pin and permits of the pin being forced downwardly until the needle penetrates a number of the uppermost sheets of paper in the paper rack. A helical spring 41 is seated-on the pin and bears with its opposite terminal convolutions against the lowermost leg of the bracket 84 and against a boss 42 formed on the pin, this springexerting a constant downward pressure upon the pin to facilitate manual insertion of the needle in the uppermost sheets, and furthermore when the uppermost sheets have been fed to the.

typewriter platen as will presently be described, this spring automatically causes the needle to penetrate the next underlying sheets so that all of the sheets in the rack will be pierced -wit-hout manual attention after the first few sheets have been manually pierced as above described. The needle thus operates to secure together the sheets adjacent to their uppermost edges, and the sheets are torn in succession from the nee washer is threaded up into abutting contact with the disk. The nipple loosely fits the shaft, and is secured thereto through the inst-rumentality of a set screw 49. While a friction roller of this kind is suitable for most purposes, it is not intended to limit the construction to this form of roller since the roller may consist of a pneumatic tire 50 carried upon the rim of a wheel 51 such as is shown in Fig. 7. This style of feed roller will not require as great a tension of the hereinafter described pressure plate for pressing the sheets of paper against the roller as the above described disk roller. It is to be understood that during rotation of the shaft 44 that the feed rollers bear upon the uppermost sheet of paper and advance the same downwardly into engagement with-the paper guides of the platen.

For actuating the feed shaft, a spur gear 52 is loosely fitted to the shaft, and over this gear and the platen rotating knob 53 a link chain 54 is trained, idlers 55 being mounted on the standard 13 andbearing against this chain to maintain the same taut. The gear 52 is connected to the feed shaft by a clutch mechanism about to be described, and when this clutch mechanism is in operative position, and the platen actuating knob is rotated, the feed shaft will be retated and the sheet of paper fed to the platen. I

The clutch mechanism consists of a cylindrical sleeve 56 which is slidably fitted on the feed shaft, connection between the shaft and sleeve being made by a pin 57 passed through the sleeve and bearing loosely within a slot 58 formed in the shaft. A tube 59 is arranged axially in the sleeve, and houses a pin 60, a helical spring .61 surrounding the shank of the pin and bearing with its opposite terminal convolutions against a cap 62 which closes the open end of the tube and against the head of the pin. The head of the pin is designed to be selectively engaged in one of a pair of notches 63 formed in the shaft, manualslid'ing of the pin toward or away from the gear 52 operating to engage the pin in either of the desired notches. Formed on the confronting faces of the sleeve and gear are opposing lugs 64, and when the sleeve is moved to its limit of movement in the direction of the gear, these lugs contact. During such contact of the lugs, it being understood that the sleeve is locked to the shaft by the spring controlled pin being engaged in one of the notches of the shaft, the gear will be locked to the shaft and cause the rotation thereof. To disengage the clutch, the sleeve is slid outwardly on the shaft until the spring controlled pin engages in the mating notch of the pair of notches in which position of the parts the lugs are disengaged.

To effect the proper working of the device, the lower ends of the sheets of paper held within the paper rack must be held with considerable pressure against the feed rollers, and to attain this end I rovide a pivoted pressure plate 65 which is loosely fitted between the side bars of the frame and is curved upwardly at its lower end as shown at 66 to underlie and conform to the curvature of the feed rollers. The pressure plate 65 is equipped on its top face with a yielding covering element 67 such as leather, rubber or the like. The lowermost sheet of paper bears without slipping upon this element. Fixed to the lowermost face of the plate adjacent its upper edge is a longitudinal bar 68 the opposite ends of which are equipped with upstanding I fingers 69 to which are riveted or otherwise secured as shown at 70 levers 71, these levers extendlng along and being pivoted to the side bars as shown at 72. The pivots of the levers thus form pivots upon which the pressure plate may be rocked, and it will thus be seen that the pressure plate is pivoted to the side bars and the free end portion underlies the pressure rollers.w Helical-springs 72" are fixed sheets of paper into tight frictional engage- Ig-"ment with the feed rollers.

A To hold elevated the pivoted end of the pressure plate in order that the free end of the pressure plate may be depressed and the paper supply replenished from time to time,

. notched bell crank levers 74: are pivoted at their elbows to the standards 45 as shown at 75, thefree legs of the bell crank levers being flattened to provide thumb rests 76.

The fingers 69 maybe moved until the notches in the fingers engage over lugs 7 6' on the fingers, thereby rocking the plvoted end of the pressure plate upwardly, and the free end. out of contact with the feed roller in which position of the parts the paper supply may be replenished. Upon release of the thuinlilrest after the paper supply has been replenished, the'helicalvsprings 72 will re-- turn the pressure plate to its operative positlon. I For guiding theend of the sheet into engagementwith the platen as it emerges from the feed rollers, a curvilinear guide plate 77 ifs' provided' at its upper edge with eyes 78 whichloosely encircles the feed shaft.

The guide plate overhangs the bottom plate of the rack, and cooperates with the latter in directing the paper emerging from the feed rollers downwardly to the rear of and into engagement with theplaten.

What is claimed, is

1. An automatic paper feed including a paper support, a feed roller at the lower end thereof, an adjustable pressure plate carried by said support and bearing against said feed roller, and a spring controlled pin carried by said support adaptedto pierce material carried thereby and hold the same together.

2. An automatic paper feed including a paper support, a feed roller thereon, a pressure plate pivotally secured to said support and frictionally engaging said feed roller, and a spring controlled pin adjustably mounted on said 5 port and adapted to pierce the material t ereon.

3.
