SPECIFICATION forming part of Letters Patent No. 477,794, dated June 28, 1892.

Application filed $eptemher 30, 189l- I erial No. 407,250. (No model.)

.To aZZ whom it may concerns Be it known that I, JOSEPH BREsLIN,a oiti zen of the United States, and ajresident of lar fibrous stalks; and it consists in mecha'n:

ism for feeding the stalks: forward without crushing them, breaking the woody matter in short pieces, and removing the hurds from the fiber. V I

The invention will be first fully described in connection with the accompanying drawings, and then particularly referred to and pointed out in-the claims.

I Referring to the drawings, in which like parts are indicated by similar reference-letters wherever they occur throughout the va- 1 rious views, Figure 1 is an end elevation of through 1111mm, Fig. 2. Fig. 4 is adetail viewin frontelevation of the feed-rollsand beara machine embodying my improvements. Fig.2 1S atop or plan view of the same. Fig- 3 is a vertical longitudinal section taken ing for the break-arm. V

The framewhich supports the working parts consists of two cast-iron side pieces A,

suitably braced the proper distance apart and securely bolted upon base-timbers A. v

. In the drawings I have shown-the forward part ofthe frame made separate from the "main frame in the form of two. brackets A which are securedto the mainframe, as shown in Fig.1; but this is not material, as theside' pieces 1 and the frame may be molded .in a single piece.

In the forwardend of brackets A are jour V naled the feed-rolls B B, the upper one of which E is fitted to slide in a slotted hearing,

so that it will bear on the material with yielding pressure, and is held inplace by springs '12, which are compressed between the sliding bearings of the roll and the caps on top.

0 are break-arms having outwardly-projectinglugs cto receive stud-bolts c, by which are bent first at right anglesto the bars and then at a right angle to the end'bendsto passover flanges a, which: project inwardfrom the brackets A These flanges, arealso slotted to receive bolts, which pass through these i 7' D and D are fixed bars, the ends ofwhiclr slots and the ends of the bars D D to secure 7 the bars in place and permit of their adj ust- I men't nearer to or farther from each other toy suit'the different'kindsof material that may be treated'bythe machine. aThebreakvbar's C, which are secured in" the vibrating arms 0, vibrate between the upper and lower-fixed bars D D, the break -arms being actuated by pitmen E, which are 'journaled upon the crank-pins which project, fromdisks e, which are keyed upon a transverse shafte. Upon :the same shaft outside of the frame-work is secured a'sprocket-wheel 6 by which the I shaft is driven. e arebrackets orstandard's, which project up from the flanges a, and e are coiled springs stretched between the upper ends of the said brackets e and the journal-pins, upon which the upperends, of the pitmejn E 'are pivoted, the object of these j springs being to cushionthe vibrating break arms and. prevent jarjwhenlthe machine is in operation.

The front of the frame: provided with a ,feed apron or board F, upon which the stalks are placed to be. introduced to the feed-rolls D D, and F is an inclined board, the lower edge Of'WhlCh is near the periphery of the feed roll B to prevent anyo f the stalks passing over, the feed-roll. Q i v ,f

In therear ofthe breakers'arc arranged two beating-cylinders G G, which are alike in construction and size and geared together to reing the fiber of much of the hurds.

upon their extended ends, and upon the 'opposite'end of the lower corrugated roll is secured a sprocket-wheel-h to receiveasprocket-chain, which passes over a wheel 6 secured upon the main shaft 9 Upon this shaft are also secured a belt-pulley g, the beater-cylinder G, and the sprocket-wheel g, which drives the feed-rolls by means of a chain 9 which passes over the sprocket-wheel 1') upon the shaft of the lower feed roll B. The.vi-

over sprocket-wheels 9 6 the wheel 9 being secured upon the shaft of the lower, beatercylinder G.

The operation of the machine is as follows: The material to be treated is placed upon the apron F, pressed into the bite of the feedrolls B B, by which it is carried between the beater-bars c of the vibrating beater, which carries it up and down in contact with the stationary bars, breaking the stalks andfreepasses forward, the leading end is caught and acted'upon by the beater-bars in the upper cylinder G, over which it is carried. The leading end is then caught and passed between the corrugated rolls H, and as soon as the 0pposite end has become free from the feedingrolls it is caught by the heaters in the upper cylinder,carried around rapidly, and switched between the beater-bars of the upper, and lower cylinders G G, thus cleaning the tail, as well as the leading end, of the fiber. In practice the apronis supplied with a sufficient amount of material, and this amount is allowed to pass the feeding-rolls before a fresh supply is introduced between them. It will be noticed that the inner bars of the vibrating breaker-frameiare in close proximity to the revolving heaters and that the stock passing over the bars of the upper beater-frame will be switched back and forthby these inner bars of the breaker until the tail end is released fromthe feed-rolls and breaker.

.None of the machines heretofore constructed and used for breaking and cleaning hemp has, so far as Iain aware, produced-a clean fiber equal in market value to the fiber obtained from cleaning by the common hand-brake.

It is also a fact that in all previous machines there is a great amount of waste of poor stock prodnce'in the form of tow. The reason of this is that none of the machines treat the material in the same or substantially the As it rapidly revolving against the broken stalks ;in my'machine, while in the hand-cleaning ary cleaner bars or rods.

In order to adapt the machine to treat difand movable breaker-bars are made adjust- 5 able, so as to enlarge or diminish a space between them, and provision is also made to flvary "the stroke of the Vibrating breakerframe. The means by which the latter result a series of holes, varying radially from the I have shown and described whatl believe to be the simplest form. of machine embodyf ing my invention; but I would have it under- I stood that I do not limit myself to the precise details of construction shown, as these may be varied by any one skilled in the art to which my invention relates,after an examination of ay drawings and specification, without deipartingfrom the spirit or scope of my invention.

i WVhat I claim isr 1.. In a machine for breaking and'cleaning ihemp, the combination of the feed-rolls, two i series of fixed break-bars arrangedv one above ithe other back of said feedrolls, a vibrating frame carrying an upper and lower series of wreak-bars arranged to alternately pass the upper and lower fixed bars, revolving beateri bars in the rear of the vibrating brake-to free the stalk from hurds, and corrugated delivery- 3 rolls to hold the leading end of the stalk while =the tail end is acted on by the heaters and istantially as shown and described.

2. .The combination, substantially as specitied, of the'iframe, the feed-rollsB B, mounted in the front thereof, the fixed brake-bars D D back of said rolls, the beatingcylinders G G, armed with beater-bars g, geared together and imounted in the frame back of the brake, the corrugated rolls H H, mounted in the frame i 'back of the revolving heaters, and gearing ieonnecting the operative parts to cause them to move together, for the purpose specified.

3. The combination of theframe, the feedroll B, mounted in fixed bearings, and separable feed-roll B, the adjustable breakers D D, the vibrating breaker-arm C, the adjustable e, and wrist-pins connecting breaker-arms and disks, the beater-cylinders G G, armed with beater-bars g, geared to revolve together, the jcorrugated rolls H, the sprocket-wheels, and

driving chains and pulley for imparting moferent kinds of fibrous stalks, the stationary lis accomplished is by piercing the disk with deliver the clean-stalk from the machine,,sub-' ibreakersO secured therein itmen-E disks 7 i 3 same manner as it is treated on the common process the stock is switched against stationaxes of the shaft, as clearly shown in Fig. l. brating beater is driven by a chain passing tion to-the parts, substantially as shown and described.

4. The combination, in a machine for break ing and cleaning hemp, of the apron, separa- 5 ble feedaolls, fixed and vibrating breakers back of the feed-rolls, two revolving beatercylinders arranged one above theeother and geared together to revolve in opposite direce tions;the said cylinder composed of heads g;

connected together by'rods g, and delivery-Io
