SPECIFICATION forming para of Letters Patent No. 506,713, dated october 17,1893.

Applicatie; ned my 23, 189s'. sean No. 475,246. (No moda.)

13e it knownA that'I, ALBERT H. MoRToN, acitlz'en of the United States, residing at Lowwealth of Massachusetts, have invented a cer'- chines for Feeding Textile Fibers, of whic the following is aspecifcation. A My invention relates to machines for feeding tejitle fibers of that class in which spiked or toothed lifting-aprons are employed to raise such fibers from-a hopper or supply box ing surface of the machine to be supplied, and the obJect of said invention is so to regufurnished thereby will be substantially uniform at all times.

In the accompanying drawings, Figure 1 is a slde elevation of a feeding machine, showingthe feed-apron and its rolls, the liftingapron and its rolls, the doer, the rotary comb and-1ts clearing devices in -dotteddines (a small part of the lifting-apron and comb be-v ing shown in full lines, a part of the frame of the machine being broken away 'for that able speed-mechanism for driving the liftingapron and a part of the system of levers which control said speed-mechanism, showlng the feed-rolls and feed-apron of said lastdotted lines; Eig.v 2, a front elevation of a part of the frame of a cottonopener or similar machine, the feed-rolls and a system of scale-levers such as may be used to control the mechanism which drives the lifting-apron. I

A represents the frame ofl the feeding-machine, the space a, inclosed by the sides of the machine, the end-piecev a', the lifting-apron B and the bottom or feed-apron C forming a hopper or supply-box, in which the stock is placed. The stock is carried toward the lifting-apron B by a feed-apron C, said aprons T C being endless belts, the apron 13 running n the parallel rolls b b and the apron C on the parallel, rolls c c', said apron B having transverse slats bprovided with teeth b3,in-

clined in the direction in which said apron B travels,and said apron C 'being driven from the apron B by gears b? c2 fast on the respective shafts of the apron-'rolls b c and engaging the intermediate gear c3. D is a rotary comb which removes surplus stock from the lifting-apron, the spikes ofl said comb being stripped by a perforated belt d, running lon said comb and on an idle-roll d', as fully described in Letters Patent to me,-No.'475,24=6, dated May '17, 1892. E represents ,the doer which removes the stock from 4the liftingapron. All of the above mentioned parts arerv ot'ia Well known construct-ion and operation, except as hereinafter stated. l

It is customary to run thelifti-ng-apron and feed-apron at a uniform rate of speed, as by a belt connecting pulleys on the shaft of the upper lifting-apron roll and on the pulley f4 hereinafter named.'

i G indicates* ak picker, opener orother mato which fibers may be supplied by the lifting-apron B, said feed-apron g conducting the fibers to feedv chine, having a feed-apron g rolls gi g2, and to another feed-roll or sectional evener-roll G arranged above the rolls asis 'shown .in the patent to Clarke and Perham, No. 245,609, dated August 16,1881. 'lhe sectional evener-roll G may represent any sectional; feed-surface between which and a feed-roller or feed-rolls the fibers are fed, as

the sectional evener-plates'or feed plaies shown in the patent to\Vhitehead,No.110,318,

dated December 20, 1870, provided the sections of such sectional feed surf ace independently yield according to thc thickness of stock passing between said sections andthe feedroll or may represent any yielding feed-roll'J or feed-plate. Such a vyielding combined with levers operated thereby constitutes an evener and is commonly used to control through intermediate mechanism, the speed of feed-rolls, according to the amount of stock passing between said feed-rolls and said yielding feed-surfaces. l

H represents a system of scale-levers in three series, the scale-levers h each resting upon two sections of the roll G', the -levers h of the second series each resting upon two levers h of the first series and the main scalelever h2 resting upon two levers h'iof the secfeed-device IOO ,2S iowsaid'beln f5,

l min-ishingathe-speed of -the..lifting`apron B,

nd series, substantially as shown i'n said Clarke and-ePerl1am patent.l I connect the system of scale-leversy operated rby'snch sectional evenersdevices Vwith a' variable speedmechanisni which drivetlnlifting-aprerr B. This variable speed mechanism consists of reversed speedcones F F', one, F, .of which is driven by bevel-gears ff', one, f, of which gears islfast on the shaft of said cone F and engages theother bevel-gear f', the latter being secured to a band-pulley f2, concentrieally therewithY and said band-pulley beingconnected by.a-band f 3 to another band-pulley f4, driven-at a uniform speed from the ma,- chinelto which fibers are fed. The cones are .conne has's 'cured toits shaft abevel pinienj"6 which engages a bevel-gearb1 on theshaft of the stantially as shown in 4said ham patent, havingsegmental gears f9 1.

upper lifting-apron rllwblF/he belt f is caused to traverseon lthe cnes by belt-shipp1ngleversf7f8 of ordinary'co'nstruction, subwhichengage each other and'having beltshipping Iiorks f f12 one of saidbelt-shippinglevers (that, vfnearest thedriven conel F) being connected by a rod]013 to one end of a lever F2, pivoted atf14 on the side of the maehineG, and the other end of said lever F2 having a slot f15 which receives the outer end' of a-lever H having its :fulcrum on the knifeedge yh3 and resting upon a knife-edge hton the main 'Scale-lever.

f Itis evident that when the sectional evenerro'llG orany part thereof is raised, the slotted end of the lever f2 will also beraised, its other end depressed and the belt f5` moved towardthe large en d ofthe driven cone Fand the small end of the driving cone F, thus diand .that'when the thickness of stock'between saidsectional evener-roll and the feed-rolls '1 g g2 ,is diminished, the sectional evener-roll -will approach said feed-rolls and the weight will by the means above deted b ya belt f5 andthe driven cone F Clarke and /Per whicllextend above and be-v secr/1e scribed raise'lhe belt on the cones F F and cause stock to be fed thereby more rapidly on to the feed-aprong. By the means above described of varying the speed of the` lifting-apron, the apron g of \the machine G will be furnished with a substantially uniform `supply of fbers.-
