Be it kownthat LULiGH Amms, a citizen of the United States of America, -esidig at Detroit, in the County of 'Wayne and State of Michigan, hame imiented 'eertain new and useful [m rovements in Paper- Feeding Devices for W'riters, he., of which the following isa specificetion, reference being had therein to the ecc'ompanying drawing&

i`his nvention relates to a feederadapted to deiiver sheets of paper, envelops, mthe like, seram to a typewriter, addreing machine or the like.

The iventio consists in the atters here- 'uafter set fol-th, and more particularly pointed out in the ppended claims.

In the drawings, Fgure 1 is a View in end clevation of a paper feeder embodying features of the invention, with &paper guide and its Operating parts removed, to give clear View of the feedig mechanisn 1. Fig. a View in section on or about- Iiue .ic-av of Fig. 1. Fig. 3, is a View. indetailof a coi-'eyer helix. Fig. 4' is an end View of the holix. Fig. is a View in detail of a helix without spindle Fig.- (i is View in lctail of u modified form of helix. Fig. i' is a view in end elevati'on of the feede' showing paper guiding means and its connecton to a. lever operatin the feedin mechanism, parts of the latter ming omitted: Fig. 8 is a pers ctive `View in det-ail, of& paper guide a-n connectios. Fig. 9 is a View in detail of a modified form of the guide. Fig. 10 .is a View in dctail of a diffe'ent n'onting ofthe guides. F ig. 11 is a View in detal of :L level' ehain pawl.

Refe'ring to the drawings, 1 indicates a substantially rectanglar open top rock or casing, into which sheets of pa r or the like may be dropped on end. T is may be of thin sheet metal, as herein shown, or of :my light material and suitable const-ruetion.

.- The bottom o' base 3 of the casing has a longitudinally disposed substantially semi crclar groove 4 or depression near each end in each of which is a horizontal shaft 5, ts real' o'tion; being joumled in an oter bem-ing n'acket 6 and the rear wall of the casing, and its forward msupported portiouextending ,to the edge of a transverse slot 8 in the bottom across the cusing adjcent the front wll thereof nt what na-y he styled. the delvery end of the csng.

I These sha ft s .are p'efeably insh with the face ot the. ca'sng bottom andeachgiorms the co'e of a sgringhelix 9 'Secured conare inturned indian a d f astene to the shutt, the body of te helix riding on the bottom of the'groove which acts as a guide 'thereion .These heliees 'are preferabfy of ..jeliees 1 2 each corresponding in pitch' and dispoition of tnrnsto the adjacent lower coil, are ca'ed by horizontal shafts 13 journale& in suitable hearing apertures in the front and back ivalls of the casingl near the top thereof, the helices turning in guide tooves 14 in the side walls 15 similar to. the

ttom grooves 4, and the shufts being preferably flush with the outer faces of the walls.

The shafts 5 and 13 are rotatedin uison hy .a spi-ceket chatin 16 passing around sp'oeket wheels 17 keyed or Secured to the outer reat shutt ends, idlers 18 directin the cl'ain so that the spockets on each si e of the ca tum over toward the center thereof es jndicated by the arrows. A lever 19 pivoted at its inner end on the back of the is slotted to emb'ace one of the stretches of the chain and a yeighted or spring pressed :wl 20the'eon is adapted to engage the ain and nove t on eacl down stroke of the leve'. Stops 21 limit the throw of the level-s so that each stroke rotates the sprockets once, and a spring 22 returns it to place.

The extended end 23 of the lever is sha ed for a convenient finger pul! retdily reac ed by the operator-'of the machine on which the eeder may -be mounted. A spring pressed pawl 24 holds the chin and s rocket against accidental movement, but yie' ds to allow the chuin to move when engaged by the level'.

The shaft driving mechansm may of course be replaced by suitable gem-s, transverse shfts with bevel pinions or like means, althou h the cho-in drive s prefer able. Similar y, the shofts of the helces mn be onitted,.us n Fig. 5, where the coil en s 25 are turned to form oxial stb slmfts on which .the upertig gers or sprockets m'e into the first wide turns of the helioesat the rear of the casin which may be considered the reoeiving en of the oasng. A par of bars 28 are each movably secured on the exterior of the casing in such; manner that a row of stub ins 29 on each may be brought into parallel spaced relation with the rear wall of the casing, and thereoy form in eifect guide grooves on each side of the asing n alinement with the sepa-ated mtal turns of the helices.

As a preferred form of constrction, the bars are each slidable on a pair of parallel studs 30 on the outside of the easing, springs 31 holding them normally projected against the stud heads, and guide bushmgs 32 on the bars preventing twisting of the bars. Apertures 33 in the sides of the casin allow the pins 29 to enter the casing. Ea end of a rock arm 34 pivoted on the ratchet or chain lover stud 35 is articnlated by a link 35 to a guide bar 28. A stop 36 on the rock arm s so disposed as to be engaged by the chain lever as the letter is nearing the end of its down stroke to Swing the arm and thus draw the bars inwardly so that the pine thereon project into the casing. When the leveris released and' raised to initial position by its springs, the springs 31 withdraw the guide r pns from the ca The ins 29 on each bar mav be replace by a t web or flange 37 (ig. 10) in which case a slot 38 takes the place of the apertures 33. The rows of pins or the webs are interrupted to clear the upper heliees and the bars are arohed or otherwise disposed to avoid the upper helix groove .tt is evident that these bars mi ht be mounted as indicated in Fig. 10 wheren they are slightl widened or made into wings 39 pivoted at t eir forward edges by hinges 40 with spri 41, their rear free edges being drawn in y thelink and rock arm arrangement used on the other 4 construction.

are in, the wide turns of the sido lelices are' opened inward and the same turns of the lower or bottom helices are open upward. At the same time the forward end coils of the helices are so disposed as to allow a sheet to dro down through the bottom slot. While olding the lover depressed the operator drops a sheet of paper into the receiving end of the cesing behind the guides, a stroke of the 'l er'upxad down advances the sheet one turn of the heliees, another sheet s then dropped in, and so on until the feedes fully charged, there being as many sheets as there are elix turns.

When needed for the typewriter, a sti-oke 'of the lever moves the sheet at the forward end of the casn over the slot in the base so that t drops trough as the helioes are turned out of its way. Thus the operator can supply machine by merely teaching the leveluntil the: feede-r is exhausted, making the dev ce especially valmble for taking dctato drectly on the t pewriter, or transcrbmg from a telegrapli receiver, or for other uses where t is mconvenient. to con tmually iterrupt the writer to replace a sheet.

The feeder may be made dea enough to take any standard sheet, addtional side hehces being added if necessary to better sup ort the sheet. It may he likewise ada-pt ed or cards, envelnps or for manifolding, a set of the paper sh ets and interposed cer hons being placed hetween each turn.

The nsepf the s ing Ielix s prefe-able to the sold screw as the light gage wire which may -be used allows a very lar -e number of sheets to be packed in a. sma space, while the yieldable spring clips which the coils constitute in efect allow for slightfir regularities in the p per.

The propo'tions of the feedemay be varied to such difi'e-ent sized sheets and any capacity may be obtained by increasing the length of the lelics or conveyers.

Ohvinusly the details of Construction may he varied without departing from the spirit of the invention, and I do not limit myself to any particular form or a-rangement of parte.

A slield 43 may be Secured to the rezuwall 7 of the casing to cover the mechanism.
