HEMP-BRAKE.

QIPECIFIGATION forming part of Letters Patent No. 448,493, dated March 17, 1891.

Application filed June 9, 1890. Serial No. 354,717. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT ANGELL, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Hemp- Brakes, of which the following is a specification.

My invention relates to that class of hempbrakes shown in Letters Patent No. 427,764, gggtgtcd to Albert Angeli, assignee, May 13,

The object of my invention is to provide suitable feeding mechanism for feeding the hemp to the brake and a pair of finishingbreakers of peculiar construction, all of which will be fully set forth in the description of the accompanying drawings, making a part oft-his specification, in which Figure 1 is a side elevation, partly in section, of my improvement. Fig. 2 is a side elevation of the same.

My invention is mounted upon a suitable platform 1, which is preferably supported on suitable groundwheels 2, so as to have a portable machine.

3 represents the main driving-pulley mounted upon shaft 4.

5 represents a sprocket-wheel on shaft 4.

6 represents a drive-chain, and 7 a sprocketwheel mounted upon shaft 8 for driving the finishing and delivering mechanism.

9 represents a drive-chain passing from the sprocket-wheel on the main shaft 4 around the sprocket-wheel 10 on the feed-roll shaft 11.

12 represents a spur-wheel on the shaft 11, driving a spur-wheel 13 on the feed -roll shaft 14.

15 represents a sprocket-wheel on the shaft 11, and 16 is a sprocket-chain engaging on sprocket-wheel 15 and on sprockct-wheel17 on the shaft 18 of the primary feed-roll.

A 13 represent two lower feed-rolls mounted upon the shafts l1 and 18.

O represents the upper feed-roll mounted above the feed-rolls A B and cent-rally between them. It is of larger diameter and adapted to force the hemp down, as it were, between the rolls A B, which prevents the breaking of the stalks, which is more apt to occur where a single feeding-roll is used.

Hence this arrangement insures a more uni form feeding of the hemp to the breaker D, which is of ordinary construction and need not be described.

The breaker and cleaner D breaks the hemp between one or more stationary breakers E and a. The hurds fall through the breaker D, and the fiber is carried onto the periphery and delivered to two secondary crusher-rolls F G, which are corrugated and serve to mash up any hard pieces or any portions of unbroken hurds which escape the primary breakers, and thus insure a complete and thorough breaking up of the stalk, so that the hurds readily fall or can be shaken out. The hemp is delivered from the final breakingrolls F G between the two aprons H I. These aprons are driven by means of the sprocket- Wheel 20 on the shaft 8, sprocket-chain 21 over sprocket wheel 20, and the sprocketwheel 22 on the shaft 23 of the lower delivery-roll K.

L represents an idler over which the apron H passes.

Motion is transmitted by means of gearwheel 24: on shaft 23 to gear-wheel 25 on shaft 26, which is the lower roll M of the deliveryapron I. The upper delivery-roll O is an idler and driven by the belt I. The object of the endless belts H and I is to prevent the hemp from being wound around the deliveryrolls.

In order to insure a proper feeding, I have shown the final breaking-rolls F Gsecured by means of adjustable bearingsNand set-screw P, so that the requisite amount of pressure to secure a complete breaking may be obtained and varying pressures may be had to suit the condition of the hemp. Thus when the hemp is very dry a less amount of pressure is required. In like manner I have shown the upper feed-roll 0 held in adjustable bearings Q and provided with an adj usting-screw R, for the conditions of the hemp require more or less pressure at different times, and this means of adjustment is provided to insure proper feeding and thorough breaking of the hemp in the Varying conditions it may be found.

Having described my invention, what I claim is 1. In a hemp-brake, the combination, with the brca'kingcleaner, of the two lower feedrolls, an upper feed-roll located above the space between the two lower feed-rolls, and mechanism for driving the feed-rolls, substantially as described.

2. In a hemp-brake, the combination, with the breaking-cleaner, the two lower feed-rolls, an upper feed-roll located above the space between the two lower feed-rolls, mechanism for driving the cleaner and feed-rolls, and means for regulating; the pressure of the upper feedroll, substantially as described.

In a hemp-brake, the combination, with the breaking-cleaner and the delivery-rolls, of the corrugated crushing-rolls located between said brcakingcleaner and deliveryrolls, substantially as described.

4. A hemp-brake composed of the three feedrolls A B C, the breaking-cleaner D, the sta= tionary breakers E and a, the delivery-aprons H and I, and the corrugated rolls F and G, located between the breaking-cleaner and delivery-aprons, substantially as described.

5. In a hemp-brake, the combination of one or more feeding-rolls, the revolving breakingcleaner D, a delivery device, and the corrugated rolls F G, located between the cleaner D and the delivery device, substantially as described.

In testimony whereof I have hereunto set my hand.

ALBE RT ANGELL.
