TYPE-WRITING MACHINE.

I 1 Application filed February TO'aZZ whom it may concern:

Be it known that T, JoHNl-I. Snnonmma citizen of the United'States, residingin Chi cago,-in the county of 'Cookia'nd State of Illinois, have invented certainnew and :use;

The magazine may contain a largelnumberof loose sheets,

their rotation, to pick' off in a sliding action, the forward sheet with which they'are' in contact, and to deliver saidsheet downwardly over the forward downwardly-1ncln ed lip or edge-of the magazine floor; it

being found by me that under this system of delivery, the rollers having highly sensitive and eiiic1ent friction surfaces, the sheets behind the one being removed, are not d1sturbed at the time of such removal.

Specification of Letters Patent.

' PatentedNotn; r, 1916." 19,1914. Serial no. 819,637.

The invention is shown as applied to ,a

typewriting machineof the usual Underwood type, wherein a platen 1 ismounted on r a shaftf2,vjournaled in: bearings on a platen; frame 3, which is moved along'the Punting 'POlIltbf the type 4,-'by a carriagefi, the. platen-frame being included in, or forming Part of, said. carriage. At the end ofeach- "line of writing, the c arriageY5 isreturned to f the starting point by means of a lever4.6,- v mounted on the said carriage, which? level",

' is also adapted to rotate or 'line space the platen, by-driving backa plunger Or'slide. v *7, thereby operating a pawl S'carried hy-said- 9 that is fast on the platenshaft 2. The paper or work-sheets 10 are supp rted in a rearwardly-inclined vertical stack in r a magazine composed of a rear-framewallf 11, side wings or walls12, and a base-13,] which base, while beingslightly uptil'ted in J its forward extension from rear wall 11 to slide, to feed a ratchet or line-space wheel- 0."

v form a normally retaining support ffor-the sheets 10 placed edgewise thereon, is provided, toward its forward I edge,"' with downwardinclination on lips 13, to slightlyifi: advance the lower edge of the forward f sheen-and to enable said forward sheetto' be slipped there'over in the feeding operation -to be described hereinafter, The saidstacli, of sheets 10 is impelled forwardly toward;

frictional feed rolls .14, mounted 0113a shaft j 15. tliatfis journaled in bearings therefor the side wings 12, by means of an auxiliary rear frame 16, lying'between the Wall 11. p

and the rear surface of.said stack ofqsheets, said frame 16 having upwardly-extending.

arms 16*, terminating in bent fingers 16",.

entered in slots 11 in the frame 11, to effect} I a hinge-like removable.- connection. Se-.

cured to said. frame "11 are a number springs 17, two of these springs being shown} in the drawings, said springs extending- I downwardly fromtheir points of connection to a point near the lower end of the;

auxiliary frame 1 6, where they exert out-1.

wardpressure against said frame 16, there "by causing said frame to force the stack of requisite degree of 'pressure.

sheets against the feed rolls 14: with the 7' The loose sheets of the stack contained the magazine aforesaid, are held fromfall ing forwardly out of said magazine, :by

means of a vertical arm" -18 ;arranged at the back of frame 11, and having vertically slid will be in front of the upper margins of the sheets in the magazine, and said arm is retained or set in that adjusted position by means of a wing-screw 11, threaded into" frame 11, through a vertical slot 18 in said arm.

The sheets 10 are fed downwardly toward the platen by the rolls 14, of which two are shown in the drawings, each being provided with frictional surfaces. Of course, the particular number of feed rolls is unimportant, excepting with regard to the uniformity of the frictional drag they apply to the sheets, and for this purpose they may be employed in suitable number and location. To enhance their serviceability, the

rolls 14 are provided with a peripheral surfacing of frictional material, and in the example shown, I have indicated at 14 a number of corrugated bands as placed frictional contact-with the forward surface of the front sheet 10 in the magazine.

Under the frictional arrangement referred to the rotation of the rolls 14, clockwise in Fig. 4, will cause the forward sheet 10 to be fed downwardly from the stack, passing, as shown in Fig. 4, between the down-turned lip 13 of the base 13 and saidrolls, and being guided thence to the platen and its feed rolls 28, by forwardly-depending guide fingers 19, which extend from a front bar 19*" connecting the wings 12, and by the usual paper shelf or table 20," upon which latter the magazine may be mounted. In the example shown, where the table 20 has the upper beaded or hooked edge 21, the lower rear edge of the frame 11 may have hook-like lugs 11 to straddle said beaded edge and thus effect a locking engagement with said table.

The magazine is otherwise removably con- 'nected to the typewritingmachine by .a

rod 22, passed through a support or lateral extension 12 of one of the side wings 12 of the magazine frame, said extension 12 being supported in a lower plane than base 13 by a connecting web 12 Said rod 22 has a hook 22 at its lower end for engagement with a rod 23 or other member on the platen frame. The rod 22, above extension 12 has a thread to receive a knurled nut 22", whereby it may be drawn tautly for firm connection of the magazine to the platen frame, or released for convenient removal thereof.

It will be understood that the weight of the magazine and its associated parts, is

carried by one of the end members of the platen frame, the extension 12 fitting therebe equal,

011, and having depending flanges 12 to secure it in position.

The extension 12 has an upstanding arm 12, to which is connected, at 12 a friction wheel 24, which may have a corrugated larly equipped, said wheel 25, being mounted on shaft 15, serving to drive said shaft and the rolls 24 carried thereby. i

The feeding operation of the paper sheets to the platen will be well understood from the foregoing description. The surface speeds of the' rolls '14 and the platen may to synchronize their action. Should the degree of-frictional contact be tween wheel 24 and the platen require variation, thisv may be accomplished by tightening or'loosening the nut 22", when a slight fall or rise-is obtainable, because an elastic about said rolls, said bands 14 being inbe rocked to the position shown in Fig. 8,-

in which position said bail cams or applies pressure against the paper sheets, moving their lower edges back over the base 13, and removing their forward surface from contact with the friction rolls'14, the device thus becomim inoperative.

It will be noted that no other fixed connections are employed in attaching the magazine apparatus to a typewriting machine, and the means for removably securing said apparatus to the carriage are of the simplest character possible. Also, it should be noted that the magazine frame work, including the mounts and supports for the operative parts, may be composed of sheet metal, and, as illustrated in the example in the drawings, may be stampedor formed out of a single sheet, thereby making for economy in construction, besides giving the qualities of strength and lightness.

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