Specification of Letters Patent.

Patented Feb. a, rear.

Application filed July 19, 1915. Serial No. 40,642.

a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Beaters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

The most general types of beaters or scrapers used in carcass dehairing machines are of the type consisting of flexible beater arms or loops of fabric or other suitable material having secured thereon metal blades or scrapers which, upon being drawn across the surface of the carcass as the beaters are rotated, serve to remove the hair therefrom. These types of beaters, however, have, in some instances, proved objectionable for operating upon certain parts of a carcass, particularly the hams, owing to. the fact that the metal blades may,in some cases, tear or injure the skin of the carcass.

It is an object of this invention to construct a beater of the general type above described, but in place of the metal blades provided with a strip or a plurality of strips of a composition material impregnated with an abrasive secured by suitable means to the beater arms, said material when drawn across the skin of a carcass,

exerting considerable friction and drag thereon to dehair the same without injury to the skin.

It is an object therefore of this inven tion to construct an improved type of beater 1 wherein flexible beater arms are attached upon a shaft by means of brackets, and have secured thereto yieldable dehairing means.

It is also an object of this invention to provide an improved means of attaching de-' hairing elements to the flexible arms of a means secured on the leading sides of the loops, consisting of a yleldab'le material 1m- 'pregnated with an abrasive affording a construction capable of exerting a considerable drag on the skin of a carcass to remove the hair therefrom.

It is finally an objectof this invention to construct a new type of beater comprising a pair of flexible beater arms provided with a non-cutting yieldable frictional dehairing means.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings: Figure 1 is a top plan view of a beater in horizontal position mounted upon a fragmentary portion of a shaft. Fig. 2 is a side elevation of the beater with the shaft shown in section. Fig. 3 is an enlarged fragmentary view illustrating attachment to the beater arms of the scraping or dehairing elements. Fig. 1- is a detail Section taken on line 4i of Fig. 3, with parts shown in elevation. Fig. 5 is a modified form of dehairing element shown detached from the means by which it is secured t0 the beater arms. Fig. 6 is a fragmentary side view of a modified form of device. Fig. 7 is a plan view of the dehairing means detached from the beater arms. Fig. 8 is a detail section on line 88 of Fig. 7.

As shown in the drawings, the heater is mounted upon a driving shaft 1, and consists of semi-circular clamps 2, which er:- actly similar in construction and interchangeable, said clamps being held togetherby bolts 3, on opposite sides of said shaft. A curved attaching plate 4, is integrally con nected on one side of each of said clam as b means of an angled arm 5, and, as clearly shown in Fig. 1, a reinforcing rib (5, is formed centrally on said clamps and merges into the arm to strengthen the structure as a whole. Ribs 7, are also provided upon the under side of said clamps to receive the squared heads of the bolts thercbetween to prevent rotation of the bolts as the nuts thereon are tightened. Adjacent said ribs 7, is an abrupt right angled web 8, also formed integral with said clamp, and integral with said web 8, is an outwardly directed rearwardly curved rigid reinforcing arm 9. beater arm or loop of relatively stiff fabric, leather or other suitable material, denoted by the reference numeral 10, is bolted at one of its ends between a clamping plate 11, and a relatively stiff short piece of fabric or other suitable material 12, which rests upon the inner portion of said reinforcing member 9, said members all being rigidly held to said latter member by means of bolts 13, extending therethrough. Ribs 14, are formed on the surface of said member 9, to receive the squared ends of the bolts 13, to prevent rotation thereof when the nuts are tightened. The other end of said fabric loop is clamped against a flexible reinforcing strip 15, upon said flat plate 1, by means of bolts 16. Riveted or secured in any suitable manner upon the leading side of the loop 10 are L- shaped metallic plates 18 and 19, which have secured between the flange ends thereof by means of bolts 20, a block or strip of suitable material for contact with the skin of a carcass in dehairing the same. This material is a composition preferably yieldable, though not necessarily so, composed largely of rub her and impregnated with an abrasive substance. .The rivets by which said L- shaped plates 18 and 19, are secured to the fabric loop, are denoted by the reference numeral 22, and as clearly shown in detail in Fig. 4:, on the inner surface of the loop are provided with relatively large washers 23, which act to prevent tearing of the rivets through the fabric or other material of which the loop may be constructed.

The form of elements 21, shown in Figs. 1 to 4, inclusive, is of substantially rectangular shape, and in the modified form shown in Fig. 5, I have illustrated an element 24, provided with a V-groove 25, in the outer surface thereof, which thus affords a greater number of scraping edges for contact with the skin of a carcass.

Figs. 6, 7 and 8, illustrate a modified form of construction wherein I employ long strips of yieldable material 26, mounted on and reinforced by any suitable material 26 said strips being corrugated on their outer surfaces and impregnated with a fine abrasive material of any suitable nature and secured in any suitable manner to the beater arms 10, preferably by means of long rivets 27. The abrasive acts, together with said material, in exerting a strong drag on the surface of the skin of a carcass, so that as the beater is drawn thereover, the hair is removed in an efiicient manner and without injury to the skin of the carcass.

The operation is as follows: When it is desired to adjust the beater upon the shaft, merely one pair of the bolts 8, is loosened, thus permitting the heater to be rotated into a desired position or moved longitudinally upon the shaft as desired. In removing the beater from the shaft, the bolts 3, are removed and one set of either the bolts 13 or 16, whichever are most convenient for the furthermore the action of the dehairing elev ments 21, upon the skin of the carcass, is eX- tremely eflicient, due not only to the flexibility of the fabric loop, but also to the manner of attachment of said elements by means of the plates and rivets to the fabric, thus permitting a springing movement of said plates carrying the elements with respect to the fabric.

In the modified form of device shown in Figs. 6, 7 and 8, in place of the separate elements 21, I have shown long strips of yieldable material such as rubber impregnated with an abrasive, and the outer surface of said strips being corrugated, a most efficient frictional effect for removing the hair from the carcass is obtained.

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. In a device of the class described the combination of flexible beater arms, and yieldable dehairing means thereon impregnated with abrasive.

2. In a non-cutting dehairing device corrugated means impregnated with abrasive for contact with the skin of a carcass.

3. In a dehairing device of the class described, a fabric loop, plates secured on said fabric loop one upon the other, and a block of dehairing material secured between said plates and projecting therefrom for contact with and operation over the surface of a. surface to be dehaired.

t. In a heater of the class described the combination with fabric loops, of superposed t..shaped plates riveted thereto, yieldable elements secured between said L-shaped plates, and bolts extending through said plates and yieldable elements to retain the elements therein.

5. In a beater of the class described they I combination with a shaft and brackets secured thereon, of a fabric loop secured'to said brackets, flanged plates riveted in superposed relation upon said loops on the leadin surfaces thereof, and elements impregnated with abrasive secured between said flanged plates afiording dehairing means on the heater.

6. In a dehairing device of the class described the combination with beater loops, of L-shaped plates riveted at their ends thereto in a manner to permit said L-shaped plates to spring relatively said loops, and

of the plates to retain the elements secured therein.

In testimony whereof I have hereunto subscribed my name in the presence of tWo subscribing Witnesses.
