An endless belt, L, works around the two rollers l" Beit known that GEORGE EDWARD BU1r1,ofH.n- 1 K, and rests on the belt @,both belts, L and E, being vard, in the county oi' Worcester, (late ot' XVestiord, in borne down upon one another, and made, between thethe count-y of Middlesex, in the State of Massari inset-ts,) rollers 'I K, to stretch overailmut one-third of the periphhas invented a new 'and useful Improvement in Mn- ,.cry of the roller G. chines for Cleaning, Separating, and Assorting Brief Another endless belt, M,'placed directly over the belt ties, 85o.; and I do hereby declale that the following is F, works around the roller 1, and a roller, N, disposed' a full and exact description' thereof, reference being had seen in figs. 7 and 9, the said belt M, as well as the to the annexed drawingsx making part of this specification, and to the letters or reference marked thereon, in'

belt F, being together led over a wheel or pulley, O, that is made to extend up-.between the two wheels or pulleys I N, as seeuin fig. v,

A fifth endless belt, P, is made to extend-in line with the belt E, and around the 'wheels or pulleys Q R.

The pulleys Q and O arcplaced side by side on one horizontal shaft, d, whilei the pulley R is situated .on another shaft, e, which also has another pulley, f, placed on it, direc`tly under the belt F, as seen in iig.9, which is a vertical section of the belt F, and the several pulleys and rollers around and with which it operates.

Figure 4 isa forward-end view of the machine.

Figure 5 is a side elevation of the upper dischargingroller and its comb-guar Figure (i is a top view of the lower discharging-roller ,the pulley H, before mentioned. Between the rollers I K, 'and overthe endless belt F, is a comb or rake, T, that is attached to the lower end of along rod or sta', g, that passes and slides freely through a short rocker-shaft, h, and receives a transverse-reciprocating movement from abelt, i., of arotating crank-shaft, K.

The lower edges of the comb-teeth are made to move in an elliptical or oblong path over the belt F, which causes the teeth to enter into and comb any bristles that may be on the belt.

Another such comb, U, is also arranged just in advance of the belt L, and by the side of the pulley O.

The said comb or rake U is operated, like the comb T, by means of a crank, l, a rod, m, and a rocker-shaft, n, the two shafts, K and n, of the cranks, Vbeing con- Figure 7 is a vertical and longitudinal section of the machine, the same being taken through the endless brush-belts, to behereinafter described.

Figure Sis a forward-end view of the assorting-appa Fi ure 9 is a section, showing the belts which seize and hold the bristles whle being combed.

Figures 10 and 11 are side and top views of' the hammer and its operating-mechanism.

Figure 12 is a side elevation, taken upon a plane at right angles to the line A B in fig. l, at the rear end of the machine.

The operative parts of the machinery are supported by a strong frame, made of wood or other suitable material.

At one, or the forward end of this frame, is a hor'i-" zontal roller, D, fixed on a shaft, A, whose journals rest andturn in boxes V V.

Two endless belts, E F, work around the roller D, one of these belts (viz,F,) being about twice the width of the other.

The narrowest belt, E, also works around a wheel or pulley, G, which is arranged as seen in gs. l and 7, and fixed on a transverse horizontal shaft, c.

' The other, or wider belt, at its front, passes around an endless belt, S, working ou a wheel or pulley,"H, which is shown in g. which is a vertical and transverse view ofthe machine, taken through the drivingshaft, It is also shown in fig. 9, to be hereinafter described. the cranks k and l, an upward-rising and downward- Two other cylindrical rollers, I K, are arranged, redipping motion, which causes them to enter and withspectively, just in front and rear of the wheel G, and draw themselves from the blistles. with their uppe` surfaces nearly on a level with and a If, when the several endless belts are made to move little above that of the said wheel G. in the directions denoted by the arrows on them, alot is put in revolution, the other will be simultaneously rotated.

It will be seen that the points of the combs or rakes T and U move in an elliptical oblong path, with an in- 'creased accelerated motion, when the combs or rakes enter thc bristles, and a lag or retarded motion when they are withdrawn.

This named increased and retarded motion of the rakes causes them to throw off any material which might otherwise adhere to and clog them. Thus the combs or rakes are made to operate andclear themselves without the aid of strippers.

The combs or rakes also have imparted to them, by

An endless belt, S, works around the pulley f and-- nect'ed by gears p q, as seen in g."l, so that where one y of the bristles is laid on the two belts E F, so as to extend from one to the other, transversely of the machine, they will be seized by and carried between the two belts E and L. This causes E and L toform clamps, which hold one part of the bristles firmly upon the wheel G, and present the other' part to the action of the combs.

When the bristles pass over the wheel G, they will be lifted off and some distance above the belt F, so that the comb or rake T can pass between them, and comb or straighten such portions of them as project out of the two holdingrbelts E L.

The bristles are next carried-downwards towards the belt F, and their combed portions are seized by and ca ried between those parts of the belts F and M, that together work over thewheel, and the bristles are firmly clamped upon the wheel 0.

The unoombed portions, or those which'were previously grasped by and between the belts E and L, being made by such operation to leave the said belts .E and L, and project beyond the wheel O, and be raised upwards in such a manner as to enable the comb U to pass into them, and, comb or straighten them out.

After undergoing the .combing-process, the bristles are made to descend and pass on to the upper surfaces of the two endless belts, F and P, which are disposed on or about on the same plane, and move attbe same velocity, and convey the bristles to the endles brushbelts Y W.

These endless brush-belts consist of two endless bands,'supported on and around wheels or rollers r--s t lu, (the'rollers lr s being placed, respectively, over the rollerst u, as seenin the drawings,) and having bristles extended from their outer surfaces as seen at c.

The upper brush-belt is arranged directly over the lower one, and at such a distance from it that their bristles, projecting from their most contiguous surfaces,

extend or mesh in between one another, like the teethV of two gear-wheels.

The shaftw ofthe wheels t and H has a gear-wheel, 2:, fixed on one end of it, which is made to engage with and be revolved by' a pinionhgear, y, that is placed on a driving-shaft, z, situated as seen in figs. 2 and S.

The endless belt F receives its motion from the pulley H, where the latter is revolved by a rotary movement of its shaft. Such movement of the belt Fimparts. corresponding movements to the several rollers and endless belts, which, as hereinbefore described, operate in connection with the two combs, T-U.

On one end of the shaft al of the roller N, there is fixed a large bevellcd gear, bl, which is made to engage with-a bevel-pinion, c, fixed on a shaft, fl.

An endless belt, il, is made to work around two pulleys, j" gl, the former being iixed on the shaft dl, while the latter is fixed on the/crankshaft K.

By such means, motion is communicated from the roller N to the shaft K, in order to put the two combs in operation.

Another bevel-gear, h, is placed on the other end of the shaft a, and is' made to engage with and turn al bevel-gear, i, fixed 0n the top of a'vertical shaft, k, the whole being arranged as seen in figs. 1,2, and 4.

An endless belt, l', is arranged as seen in, said figures,

v and so as to work horizontally around' two pulleys, m

n, Vfixed respectively on the two upright shafts k o. The inner face of the belt is inclined towards the two brush-belts V W, andthe front pulley of the endless beltP, and behind,against the inner portion-of the belt l, a 'spring or board, pl, is placed, as seenin iig.' 1, it4

being supported' at or 'near its rear end by a standard or post, ql.

A small hammer-lever, fr', is yarranged against the outer face of the board'p, as seen in figs. l, 2, and 10, the latter figure being a vertical section of the hammerlever and its slide-shalt, and the spring thereof.' The said hammer r* turns 011 a fulcrum, s, and is jointed at its lower end to a sliding horizontal shaft, tl, from which a projection, u,cxten`ds', as seen in fig. 1.1, which is a top view of this shaft, and the driving-shaft adjacent to it. i

A cam-wheel, 1v', ariixed on the driving-shaft, and

' provided with a series` of cams on its side next the arm n, so acts against the said arm during the rotary movement of the driving-shaft, as to successively move it in one direction, and allow it during such movements to be moved back in the opposite direction by a spring, w.

This longitudinal movement of the shaft causes the hammer 'r to rapidly strike against the board 1J, or a small anvil, x, attachedto it. Now, as the bristles are moved along by theendlcss belts P and F, their ends next the belt l* will be carried in contact with such belt, and by means of the concussion of the raps or blows of the hammer -r against the spring-board p', these bristles will be so agitated or disturbed as not only to prevent an adhesion of their but-s or roots to the guide-belt l', (whereby, by the forward movement of the endless belts, on which they rest, the bristles would be liable to be thrown around or out of place,) but also to cause. them to settle properly on the supporting-belts, for presentation to the endless brushbelts.

The bristles are received at their buts by the twov endless bmsh-belts, and are held by and between the bristles thereof,

As the bristles so held, are of various lengths, they are next to be seized and drawn away from the brush-.

belts, the longest ones being the tirst, and the shortest being the last to be drawn away.

The mechanism for producing this effect may be thus described: Four rollers or cylinders avz lf" cz cl2, of different lengths, are arranged respectively on four parallel and horizontal shafts e* e? e2 e", that are disposed obliquely to the vertical plaire of the two endless brushbeltsv lV, all as seenjp fig. 1.

Justin frontof and below each one of these rollers, is a larger roller, f 2, g, hg, or i, made of the same length as the roller to which it appertains.

The upper edge of either' ofthe lower rollers f2, y", h, 0r i2, is made to Stand somewhat above the lower edge of the roller b, c2, or di', above and next adjacent to it.

A series of endless` belts L: l m2 n? 02122, is applied to'the upper set of rollers a2 l12 c2 d. The'rst or longest,

that extends around the rollersf2 g2, as seen in iig. 3.

The next endless belt P extends from and around the roller: b2, and the upper of twogrooved deliveryrollers qi i, and goes over and under said rollers c2 di.

The endless belt n extends from the roller b2 to the' roller rl, and goes both above and below the roller c.

So, with the next belt n, it extends from the roller cE to the upperdelivery-roller q2, while thebelt 'o 4extends from the roller c* to the roller d.

.Each belt k2 I* ml n2 ol operates inconnection with an endless belt placed under it, and madeto pass around some of the rollers 7"2 y? l'i, as doessthe belt q.

rlhe last, p, travels 'around the roller' d and the upper delivery-roller q, and it has its belt r under it, which belt plays around the roller i2, and a pulley or wheel, s1, fixed on the shaft of the roller h2. The upper vdelivery or disehargingrhroller q, as well as the lower one, i, lis constructed with numerous grooves t2 t, ex-

A suitable box o`r receptacle, w', is arranged to receive the bristles as they are discharged from the delivery-rollers.

I would remark that the endless belts of the deliveryrollers are to move with the same, or about the same velocity as that of lthe endless brush-belts; also, that ,the rollers a 7) c2 are placed at different distances from the two belts V W, the roller c"I being nearelI thereto' than the roller b3, while this latter is nearer than the roller a.

Now, as these latter belts, viz, V W, hold the bristles at their buts, and as the bristles are of various lengths,

` they will be seized by and between the endless belts It m*- oz, and those directly under them, and drawn out ofthe brush-belts, those bristles beyond a certain length away from the brush-belt bythe belt o?, and that directly under it. Finally, t-he bristles in assorted sizes, will be delivered into the box or receptacle 102.

The proper movements of the endless-belt draught and delivery-mechanism are produced by rotating the lower delivery-roller, and in order to do this, tlrere'is a bcvelled gear, x2, fixed on its shaft, and made to engage with another such gear y2, placed on the shaft z2 of the front roller of the lower endless brush-belt, (see fig. 12,) which is a rear-end view of the machine.

In order to clean each of the brush-belts V W of the refuse bristles that may be left in them, 1 apply to each of them a stationary comb, as seen at r1.3 b3, in tigs. 7 and 12.

These combs discharge the said refuse upon a platl form or into a suitable receptable, (Z3.

What I claim as the invention of the said GEORGE EDWARD BURT, is as follows:

1. A machine for combing bristles, combining in its construction the following elements, viz, a Acomb, a

clamp for holding the bristles while subjected to the action of the comb, and suitable mechanism for passing the comb through the bristles, and for combing the same, substantially as set forth.

'2. In combination with the comb, a movable clamping-apparatus, by which the bristles are brought into 'proper position .to be acted upon by the combs.

3. The combination of the movable combs T and U with the clamping-belts E and L, F and M, combined and operating substantially as described.

4. In combination with the dragging and conveyingmechanism, the double brush-belts, arranged to act as conveyes, substantially as set forth.

5. Amachiue for dragging and assorting bristles, combining in its construction the following groups of elements, viz, mechanism for combing the bristles, a conveying-mechanism, for canyiug the bristles after being subjected .to the action of the comb, and mechanism for successively taking up the bristles of dit`- ferent lengths, substantially as described.

6. A conveyer so arranged, as to clamp the bristles between two surfaces, for holding them in such a manncr that one end of the bristles may project therefrom, in combination with an asserting-mechanism, so arranged in relation thereto, that the bristles shall be separated and taken ont successively, according to their lengths, substantially in the manner setforth.

7. The spring-board p, and hammer r, combined and arranged to operate vsubstantially in the manner and for the purpose specified.

8. The combination of the combs u2 c, with the grooved delivering-rollers, arranged to operate substantially inthe manner and for the purpose specified.
