MACHINE DISINTEGRATING FIBROUSSUBSTANCES.

SPECIFICATION forming part of Letters Patent No. 541,648, dated June 25, 1895. Application filed February 10, 1894 Serial No. 499,807. (No model) To all whom iii may concern:

Be it known that I, McOLINTooK YOUNG, of

Frederick, county of Frederick, and State of.

for the purpose of hackling or disintegratingthe fiber of the palmetto boot, in order to adapt the same for use in the manufacture of brushes and for similar purposes.

The machine, is intended to'deal with the large pieces of the bark-or boot which have been crushed or otherwise treated to partially loosen the fiber.

The machine is based upon the combination of a support for the boot, with rotary .cylin-,

ders armed with protruding h'ackling teeth.

In its preferred form, intended to treat automatically the massof fiber presented to it,

the machine consists of a supporting table,

endless feeding chains betweenv which the boot'is grasped and moved along, and two cylinders located on opposite sides of the feed chains so that their teeth',1nay act endwise on the exposed boot. Thefcylinders are each made of increasing diameter from one end toward the other, or in other words, composed of a series of short cylinders of different diameters, arranged end. to end so that the teeth of the different sections will act successively and to different depths into the boot.

In the accompanying drawings, Figure lis a side elevation of my machine. -Fig.- 2 isa top plan view of the same. Fig. 3 is an ele-.

vation of the receiving-end. Fig. 4 is an elevation from the opposite or delivery end. Fig. 5 is a side elevation on an enlarged scale, showing two of the co-operating feed-chains, the frame being shown in vertical section.

Fig. 6 is a vertical cross-section on the line 6 6.

Figs.7 and 8 are detail views of the feed-chains.

Referring to the drawings, A represents a 0 and 0' are the two hackling cylinders arranged horizontally on opposite sides of the table, their shafts mounted at their ends in suitable bearings on a level with the table or substantially so. These cylinders while mounted in the same horizontal plane are out of line with each other, one being arranged at one side'of the table and the other at the opposite side, as shown in Fig. 2, and they are to be rotated in opposite directions so that both will turn inward or toward the table. Each of these cylinders increases in diameter step by step from one end to the other, and each of the sections is provided with a series of projecting teeth of steel wire or other suitable material. volve closely past the edges of the table, which are stepped or cut away to correspond with the var'yingfdiameter'of the cylinders.

D, D, D andD represent four horizontal feed chains arranged in pairs to carry the material between them past the hackling cylinders and in such proximity thereto as to subject it to the action of the same. The firstpair of chains D and D, are mounted to travel around supporting pulleys d, at their ends, one lying below and the other above the table, which is slotted longitudinally in a line passing between them, so that the upper surface of the under chain and the under surface of the upper chain may co-operate and grasp firmly between them, the fiber boot E lying crosswise of the. table, as shown atFig. 6. The active sides of the chains are supported and guided in stationary channeled plates F, F bolted to the main frame, the upper plates being sustained by overhanging arms forming part of the main frame, as shown in Fig. 6, in order to leave anIunobstructed space for the passage of the fiber over the table.

The chains are made up of a series of articulated plates or links, such as shown in Figs. 6 and 7, corrugated longitudinally and joined at their ends on lines oblique to the line of travel, so that the surfaces of the chains will afford a continuous support for the transverse fiber, and prevent it from falling into the joints between them. -The corrugations of the chain plates'enable them to grasp the fiber the more firmly between them,

so that it may not be drawn endwise or other-.

The teeth of the cylinders rewise displaced by the action of the hackling teeth.

I prefer, in order to prevent the cutting of the fiber, or any injurious crushing of the same, to provide one or both of the chains witha facing of rubber or equivalent elastic. material f. (See Fig. 6.)-

On reference to Fig. 2 it will be observed that the larger sections of the two. cylinders overlap each other. This is for the purpose of enabling the material to be hackled, disintegrated, or' separated, throughout its entire length, each cylinder operating beyond the midlength. It will also be observed that the two pairs of chains whereby the material'is carried past, and presented to the action of,

the respective cylinders are out of line with each other so that they will respectively grasp and hold the material at opposite sides 015 its 1' midlength. Thus the. chains D D when they receive the material from the chains 19, D grasp the hackled or disintegrated: portion and present the unhackled end to the cylinder 0 which, as before stated, overlaps the cylinder C, whereby the whole: of the material is presented to the action of the two cylinders and is disintegrated throughout its.

length.

The first pair of chains=is intended tocarry the fiber over the tableiirom the receivingend past the first. cylinder G, which acts. to

disintegrate the boot. 'firom one end to, or

Motion may be communicated to theva rious partsabove described by anysniltahlc diri-ving car.

a In the machine shown the hackling cylindcrs are; each provided. with a dirivingpul'ley c, towhich the driving belt maybedirectly applied.

The last named pinion drives the gear 0 on ashaft carrying thesupportingpulley-d Motion is communicated through intermediate pinions to the. upper chain of this pair. The carrying pulleys at the delivery end of the forward chains 1D, D are mounted on the same shaft; c as the carrying pulleys-for the forward endsofi thflSGGe 0nd chains, and thus it is that the second chains communicate motion to thefirstt lever 0 from which a controll ing rod o extends to. the front of the machine within con venient. reach of the operator.

While I have described a complete and automatic machine adapted to treat the two ends of the boot in its course therethrough I and to feed the fiber automatically, it is to be understood that any other feed mechanism may be employed and that the machine may :4 be constructed with a single cylinder and the 3 fiber treated first at one end and after being reversed, treated at the other end by the same 1 cylinder.

, Provision is made for adjusting the tension of the chains and for raising and lower 'ing'their guides, but these features are not deemed of special importance.

Having thus. described my invention, what i I clairn is 1. In a. machine for disintegrating the pal- .mettoboot. the combination: of a fixed rigid table adapted to give support to the boot while being acted on, a cylinder adjacent to 1 thetable provided witlr hackling teeth, and a feeding mechanism independent ot the table and: adaptedto grasp the boot and advance 1 the same along the tahlelongitudinal ly there- 1 of and in a direction transversely of thelcngth of the bootwi th the-end 0t thelatter presented ate the cyllinder over the edge of the table; whereby asnpport is given to the portion of the boot not acted on, independently of the feeding mechanism, which latter acts simply to advance the. boot along the table.
