MACHINE FOR BREAKING AND SHAKING HEMP.

SPECIFICATION forming part of Letters Patent no. 622,433, dated April 4, 1899.

Application filed July 25, 1898. Serial No. 686,819. (No model.)

To all whom, it may concern:

Be it known that I, ALBERT ANGELL, acitizen of the United States, residing at Orange, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Machines for Breaking and Shaking Hemp, fully described and represented in the following specificationand the accompanying drawings, forming a part of the same.

The present invention relates to that class of hemp-brakes in which the hemp-stalks are broken over the edge of the break-bar'and are subsequently beaten and scraped by the slats of a revolving beater to loosen the pith and bark therefrom; and the object of the present invention is partly to arrange the revolvingbeater below the top of the break-bar, so that the crushed fibers may be delivered to the beater by a leather flap, which is vibrated by the beater-slats, and thus shakes the fibers during the cleaning operation.

Another object of the invention is to separate the pith and bark from the stalks before they are subjected to the revolving beater, which is effected by the'vibrations of the said flap.

Another object is to remove the pith and bark which are shaken from the fibers and to prevent such materials from falling upon the beater-drum; and this object is-accomplished by an apron extended transversely-above the drum adjacent to the vibrating flap.

Another object of the invention is to facilitate the shaking of the fibers after they are subjected to the revolving beater to shake therefrom the broken pieces of wood or shives; and this object is accomplished by providing delivery-rolls adjacent to the beater and extending a leather or flexible funnel from the opening of such rolls. The fibers are delivered through such funnel, and the latter is vibrated laterally, so as to shake the fibers as they pass from the machine.

In carrying out this invention the feedboard of the machine is preferably inclined upwardly to the feed-rolls, which construction permits the elevation of the rolls and the arrangement of the beater-drum below the break-bar at a suitable height from the ground to accommodate the chaff which falls beneath the operative parts of the machine.

These improvements greatly facilitate the feeding of the stalks to the machine and clean the fibers in the most effective manner, while they also protect the operator from the dust and chaff which are beaten from the .stalks.

' The invention will be understood by reference to the annexed drawings, in which Figure 1 isa cross-section at the middle line of Fig. 2,'and Fig. 2 is a plan of the apparatus with the top cover removed. Fig. 3 is a plan on line 3 3 in Fig. 1. Fig. 4 is an elevation of the machine, viewed from the righthand side,with reference to the feeding-board G; and Fig. 5 is an elevation of the left-hand side.

The machine is constructed with two side frames A, having bearings for the shafts of the different rolls and drums. The beaterdrum B is mounted upon shaft B at about the middle of the frames, and the break-bar O is secured atits opposite ends to the frames and set a little above and at the right of the.

is inclined downwardly and forwardly from the outer side of the guide-roll. The lower side of the break-bar is provided with an angle-bar b, which serves to strip the stalks from the rear feed-roll and direct them upwardly across the face of the break-bar. A break-drum H is mounted upon a shaft H, which is located over the front edge of the break-bar, and the break-drum is provided with blades h, which break the stalks over the upper front edge of the bar and throw them backwardly. A flexible flap I, formed of leather or equivalentmaterial, is attached to the rear side of the break-bar and extended backwardly over the beater-drum B. In such position the weight of the fiap throws it downwardly against the slats b of the beaterdrum, which'throw it intermittingly upward, and thus vibrate it rapidly. Adjacent to the free edge of the vibrating flap an apron J is extended transversely across the machine over the tops of the frames, which are cut down at such point close to the top of the beater-drum. The apron is mounted upon rolls and 7a, the latterbeing supported outsideiof the frame by bearingsj and the apron traversed toward such rolls, so as to deliver the chaff beyond the frame upon the ground. In this location the apron receives the wood and shives which are beaten from the stalks by the break-drum H and also the pith and bark which are shaken from the fibers by the vibrating flap I, the chaff which is cleaned from the fibers by the beater-drum B being thrown downward beneath the machine. A cover K is extended over the beater-drum and apron and downwardly at the rear side of the same to confine the chaff thereto, the cover being open at one end over the roll 70, where the chaff is discharged. A pair of deliveryrolls L is mounted upon shafts L (at a common level) at the side of the beater-drum opposite to the feed-rolls, and a guide-roll M is arranged upon'a shaft M above the deliveryrolls to guide the fibers thereinto as their forward ends are advanced over the beater-drum. Bars N are extended between the frames A beneath both of the rolls L to form longitudinal supports for a leather funnel O, which is extended downward from the opening of the delivery-rolls, so that the beaten fibers pass through such funnel. The lower end of the funnel is contracted to just pass the fibers, and a bar 0 is attached to one side of such end and connected with vibrating rods 1), which are actuated by eccentrics 1) upon a rapidly-revolving shaft P. The shaft P is connected with the shaft E of the guide-roll E by gears 6, one of such gears being driven by a pinion 6 upon the break-drum shaft H, as shown in Fig. 5. The same gear 6 is also meshed with a gear on upon the shaft of the guide-roll M. The feed-rolls D are geared together and to the guide-roll E by gears d,and the delivery-rollsL are geared together and to the guide-roll M by gears l. The shaft M is geared to the shaft J of one of the apron-rolls by worm-gearing J 2 J 3 s s, and all the parts of the machine are thus rotated at suitable speeds, the drums B and H at a high rotating velocity and the rolls and apron at a much slower speed. Shafts B and H are connected by gears Q and driven by pulley R.

Operation of the machinc.The stalks F are fed upwardly by the rolls D across the front face of the break bar 0 and when broken by the drum H are driven backwardl y over the flap I. The flap beats them by its vibrations and throws the wood and shives upwardly upon the apron J. As the fibers F pass from the vibrating end of the flap they fall upon the beater-drum B, whose slats I) scrape and beat the fibers and dislodge the particles of pith and bark therefrom. The

delivery-roll nearest to the beater-drum is.

covered with a layer of india-rubber, as shown in Fig. 2, and serves to draw the loose fibers from the periphery of the druminto the space adjoining the guide-roll M. The fibers are thus guided downwardly between the delivery-rolls into the funnel O, which, being made of leather, india-rubber packing-cloth, or equivalent flexible material, is rigidly secured at its upper edge to the bars M, while its lower edge is vibrated rapidly by the connecting-rodsp. The fibers are thus shaken violently as they pass through the funnel and the dirt and chaif are thoroughly separated therefrom by such vibrations. An operator catches the fiber as it comes through the funnel, or it may be caught and delivered by a traveling carrier. \Vhen the rear ends of the stalks have passed over the break-bar, the fibers are driven downwardly by the rotation of the beater-drum, as shown at f, between the beater-drum and the nearer delivery-roll, and the forward ends of the fibers are then propelled by the delivery rolls, their rear ends receiving a continued beating by the drum B until they are drawn entirely through the delivery-rolls. v

lVith the construction described it will be observed that the stalks are fed directly upward across the front side of the break-bar O, in which position a large part of the wood and shives (which are loosened by the breakdrum) is enabled to fall away from the stalks upon the outer side of the break-bar and is not therefore carried toward the beater-drum to clog the same. To effect this operation, one of the feed-rolls D is placed directly underneath the break-bar O and the center of the break-drum shaft H is placed directly over the front edge of the break-bar, so that the stalks are fed directly against the bottom of the break drum. After the fibers are broken upon the break-bar they are subjected to a shaking and beating three separate times in their progress through the machineefirst, by the vibrating flap I; second, by the periphery of the beater-drum B, and, third, by the vibrating funnel 0. It will be observed that the rear ends of the stalks are beaten by the drum B the same as the forward ends after they have passed the break-bar, as they then hang down between the elastic surface of the delivery-roll L and the slats of the beaterdrum, which are adjusted to touch the elastic body of the roll.

Having thus set forth the nature of the invention, what is claimed herein is- 1. In a hemp-brake, the combination, with the revolving beater-drum B, the break-bar 0 arranged above the top of the drum at one side of the same, and the break-drum H having shaft H arranged above the front edge of the break-bar, of the pair of feed-rolls D arranged at a common level, with one of them underneath the break-bar as set forth, the guide-roll E below such feed-rolls, the feeding-board G inclined downwardly from such guide-board, and the rolls operated to feed the stalks directly upward in the front of the break-bar against the lower side of the break drum, as and for the purpose set forth.
