Be it known that I, JOSEPH B. Hows, a citizen of the of Worcester, and State of `Massachusetts, new and useful Improvements in Automatic Feeders, of whichthe following is a specication.' v

This invention/l relates to an automatic feeder for delivering fibrous materials to preparing machinery used in various textile industries. While the invention is not limited in its application to .y the Vhandling of any particular kind of ber, nor to the delivery of the ber to any particular type of preparing machinery v especially intended for the feeding and delivery of cotton .waste and other cotton ber to a' cleaning machine, which removes for-y eign mattenand leaves the cleaned ber in condition for subsequent mill processes. y.The invention' -is also well adapted to "be machines of atnt of the Bramlwell2 N o. comprismgg a casingin which the brous material is deposited, and a spike "apron in the county ofv Worcester the ty e shown in Letters Unitedp S tates tov W.

in the casing, by which the bers are elevated to the uiper part of thev casingV and thence delivere upon a travel'- mg apron which carries thematerial to the machme by which it is to be next treated. i y he invention will therefore be illusvtrated as embodied in a feeder for deliversuch as low gradecotton or waste, from a machine of the general type Bramwell patent mg machine, but it will beunderstoodthat it r1s not to such particular environmail: oil use' i dr 1n h -t e accompan awings w 'c ymwdimellt of the in- Figure 1 isa side view, partly in longitudinal section, showin the feeder, part of a 'cleaning'.machmaan part of the casing of Cnt with which the feederV is associa j Specication ot Letters Patent.

the cleaning machine B, comprises Ithe two side frames 1, secured to the sides l of'the casing A,- one on eachside. The frames larel provided with means for limited vertical adjustment consisting'of the slots 2,- and bolts 3. A conveyer vbelt or slatapron 4 extends between suitable rollers 5 .and which are supported'at their-ends by journals on the 'side frames 1. The apron 4 Iis driven in any conyenient manner, Aand its tension may be regulated by adjusting the roller 6, forward or backward by means v of adjusting screws 7'.

ron 4 is a preer belt or tween rollers 9 and 10. The tension of apron 8 is regulated by ad- -justingscrews 11 which are adapted to adjust the roller 10'toward and fro/m roller 9. The apron 8 is arranged at an angle to apron 4, thus providing a space between the two Above the slat-a belts .which is -wide at the entrance to rea line close to the accommodates itself to any ceive the incoming stock, and converges toward the delivery end yto press the stock into a comparatively thin flat mat. The bearings of roll 9 are movable on the side frames 1 toward and from the apron 4, and compression springs 12 acting through rods 13 normally press roller 9j andthe corresponding endv of apron 8 toward apron 4. The stock is passed under yielding pressure between'the two aprons, while the apron 8^ lumps orv inequalities inthe stock. The apron 8 is driven'at the same speed as apron 4 through gears 14 and 15 iied to rollers 5 and 9 respectively.

1,6 is an adjustable, inclined slide, extending from side to side of the feeder, and from delivery end of the apron 4 downward toward, but terminating short of, the feed plate b. The slide 16 is supported by brackets 17, 17, one ateach end, which are fastened by slot and bolt connections to the side frames 1, 1, thus providing means for adjustingv the slide 16 toward and from the end of apron 4.

18 is areciprocating pusher plate, preferably curved or scoop-like in form, so that the lower forward part extends approximately parallel to the feed plate 1),.while the upper part extends behind and approximately parallel to the slide 16. The pusher 18 has on its rear or under side a pair of ears 19, each pivotally connected by a link 20 to the forward end of an arm 21 bolted to o'ne of the side frames 1.. A pair of actu- .ating rods 22 are pivotally connected to the ears 19. below the points at links 20 are pivoted.

On the underl side of rods 22 areca'm surfaces 23 which, ride on rollers 24 journaled on the insidesof arms 21. The cams 23 are so shaped that as the rods22 are reciprocated endwiseand the pusher 1 8 is swung onv links 20 the forward edge of pusher plate 18 will be held close to,`but clear of the feed plate b in all positions ofthe pusher, and will be guided in a path substantially parallel to the feed plate.l rods 22 are reciprocated by a rock shaft 25, 'ournaled between frame.. 1, through arms 26 fast on the rock shaft and pivoted to rods 22. The rock shaft is 'in turn actuated by .a rod 27 which. is connected at one end to which the an arm 28 fast onthe rock shaft and at the other end toa wheel or eccentric- (not shown) on the outside of casing A.
