JAMES'P. HILLARD,( )F FALL RIVER, MASSACHUSETTS.

WASTE-PICKER.

SPECIFICATION forming part of Letters'Patent No. 430,474, dated June 17, 1890. Application filed Fehrnary'Y, 1839.1, Serial No. 298,952. (No model.)

To aZZ whom it may concern:

Be it known that Lllmuns P. IIILLARD, of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in YVasteJPickers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvement in machines for separating the fiber from the twisted threads of waste, by which the same is made applicable to woolen, silk, and other waste.

The invention consists in providing one or more chambers with solid-web boaters constructed to open, tear, and separate the fiber from the thread, and one or more chambers with open-rod beaters, by which the threads are collected, and from which the separated fiber is discharged, as will be more fully set forth hereinafter.

In the drawings similar numbers of reference indicate corresponding parts through out.

Figure 1 is an end view of my improved machine. 2 is a vertical cross-section of the same. Fig. 3 is a top view, the upper half of the case being removed. Fig. 4 is an enlarged sectional view of one construction for securing the pins in the case or housing. Fig. 5 is a sectional view showing the pin-bar secured in the side of the case.

The waste made in the various steps in textile manufacture consists of a tangled mass of thread and fiber. In woolen and silk mills cotton thread is frequently twisted with the woolen or silk fiber. The recovery of this fiber is very desirable.

In Waste-picking machines as heretofore constructed the heaters were constructed so that the thread was separated from the fiber and collected by winding on a shaft. In these machines much of the thread is wound on the shaft before all the fiber is separated from the twisted thread, causing a considerable loss of fiber.

The object of my invention is to separate the fiber more completely from the thread, and to accomplish this purpose I construct a waste-picker with one, two, or more chambers, in which a heater revolves, so that while cutting, tearing, and opening the waste it cannot wind the thread to retain the same. From this openin chamber or case I pass the torn and opened waste through one, two, or more chambers, in which the fiber is separated from the thread and the thread retained and the fiber discharged.

In the drawings, 10 designates the improved beater. It consists of a shaft on which two solid-webbed win are secured or formed spirally. The outer edges of the spiral wings of the beater 10 are formed into projecting points 12, which extend close to the inner surface of the case and pass between the'pins 11, secured in and projecting inward from the ease. The case 13 is made conical, being of considerably greater diameter at one end than at the opposite end. The small end is the receiving end, and it is provided with the hopper 151:, the larger end being provided with he discharge-opening 15. The beater 10, instead of being 'novided with two solid wings, as shown, may be provided with three or four solid wings, or the pins .16 may be secured in the shaft of the beater 10, as is shown in the drawings, so as to increase the number of tearing-points. The case 17 is also in the form of a truncated cone, smaller at the receiving end than at the discharging end. It is provided with an opening corresponding with the discharge-opening 15 of the case 13, and it is also provided with the dischargeopening 18 at the larger end. The case 17 is provided, like the case 13, with the pins 11, projecting inward. The shaft 19, formed with the rods 20, extending from the shaft to near the inner surface of the case, is provided with a longitudinal groove 99 and forms the beater and separator of the fiber from the thread, the thread being wound on the shaft 19 in the operation of the machine. The two heaters are connected by the belt 21, extending over the pulleys on the ends of the two shafts of the heaters.

22 indicates a fan revolving with the shaft 19, and itcreates draft through the beaten cases and facilitates the moving of the waste through the picker, as also the discharge from the outlet 18.

The essential difference between the two boaters is that the beater 10 is provided with solid wings, by which the thread is prevented two cases, one provided with a solid-wing beater and the other with the open-rod beater, the fiber is not thoroughly loosened and separated, two or more conical cases with solidwin g heaters maybe used, connected by openings 15, thoroughly to tear and open the waste, and one, two,or more of the cases provided. with the old open-rod heaters may be used to collect all the thread and thoroughly separate the fiber from the thread.

I do not want to confine myself to the use of any fixed number of cases and heaters of either kind, but vary the number with the kind or nature of the waste to be picked and separated.

The pins 11 are secured in the pin-bar 23, and these pin-bars are secured in the joint between the upper half 25 and lower half 26 of the case either by bolts 27, passing through the pin-bars 23, as is shown in Fig; 4, or by bolts 28, forming part of the pin-bars 23, as is shown in Fig. 5.

2% indicates the frame or standard on which the cylinders are supported.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1 I11 a waste-picker, the combination, with a case provided with an open-rod beater constructed to separate the threads from the loose fiber, of a case having inward-projecting points and provided with a solid-web beater having serrated edges, the two cases connected by an opening, the Whole constructed to tear and open the waste in one case and separate the threads from the waste in the other, as described.

2. The combination, in a waste-picker, with the conical cases connected together to form a continuous passage through the cases from the inlet to the outlet and provided with inwardly-projecting pins, of a shaft provided with pins extending from the shaft to near the casing, forming an open beater journaled in the ends of one case, a shaft journaled in the ends of the second case, provided with one or more solid webs extending from the shaft to near the. casing, the outer edge of the web being provided with projections, and means for rotating the shafts, as described.

3. The combination, with the conical case 13, provided with the pins 11, the hopper 1+1,

and the discharge-opening 15, of the beater 10, consisting of two or more wedge-shaped solid webs, secured spirallyon the shaft, constructed to tear and open the waste delivered to the beater at the smaller end and discharge the same near the base of the conical casing, as described.

4. The combination, with the conical case 13, provided with the pins 11, hopper 14, opening 15, and the spiral solid-web beater 10, of the conical case 17, provided with the pins 11 and the outlet 18 at the base of the conical case, the shaft 19, provided with a longitudinal groove, the rods 20, the fan 22, and means for rotating the shafts, as described.

5. The combination, with the cases 13 and 17, connected together by the openings 15 and provided with the hopper 14; and discharge-opening 18, of the pin-bar 23, secured between the upper and lower parts of the casing, and the standards 24, as described.
