FINISHING-ROLL.

SPECIFICATION forming part of Letters Patent No. 546,868, dated September 24, 1895.

Application filed April 19, 1895. Serial No. 546,398 '(No model.)

To all wftom 2325 may concern:

Be it known that I, IRA VAUGHN, residing in Salem, county of Essex, and State of Massachusetts, have invented an Improvement in Finishing-Rolls, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to a novel construction of roll for operating upon hides or skins, and is an improvement upon operating-rolls of the class shown and described in United States Letters Patent No. 274,859, dated March 27,1883, and No. 344,069, dated June 22, 1886.

The operating-rolls shown in the patents referred to are provided with a plurality of substantially-long threads or flanges extending in opposite directions toward the ends of the roll, and with smaller flanges or threads which extend from the main flanges or threads at an angle thereto. The long flanges or threads of the rolls shown in the patentsreferred to extend from a transverse line at the center or other point intermediate of the ends of the roll and run or extend in opposite directions to the ends of the roll at the same or substantially the same angle. These rolls are now employed for unhairing, fleshing, putting out, stretching, 850., and are efiective therefor 5 but practice has demonstrated that when the hide or skin has been put through the putting-out machine-such, for instance, as shown and described in United States Patent No. 444,173, dated January 6, 189lthe hide or skin is put out or stretched, but not in a satisfactory manner, owing to the fact that the stretch on opposite sides of the transverse line is in the same direction, and as the neckand-shoulder portion of the hide is of a different shape from the body portion the stretch of the neck-and-shoulder portion in the same direction as the body portion leaves in the hide or skin the original fullness or bag formed by the shoulders, whereas the original fullness in the body portion formed by the hips of the animal is taken out.

This invention has for its object to provide a construction of operating-roll by which the bag or fullness in the neok-and-shoulder portion of the hide, and which is left in the hide or skin in the putting-out operation, may be taken out and the hide or skin further enlarged or stretched to the extent of such bag or fullness; and this operation, which is now performed by hand, I prefer to distinguish from the putting-out operation by hereinafter referring to it as the finishing operation and to designate the improved roll as the finishing-roll.

In accordance with this invention the finishing-roll is provided with two sets of vanes, flanges, threads, or blades extended spirally in opposite directions from or about a transverse line through the roll, preferably at or about two-thirds its length, the short set of vanes being extended at a different angle from the long set of vanes and each short vane preferably having its co-operating long vane, whereby the body of the hide or skin is stretched and smoothed in one direction by all the long vanes and the neck and fore part of the hide or skin are stretched and smoothed out in an opposite direction by allthe shorter vanes, but at a dilferent angle, which takes out the bag or fullness formed by the shoulders.

Figure 1 is a plan view of a pair of finishing-rolls embodying this invention; Fig. 2, end elevations of the rolls shown in Fig. 1, and Fig. 3 an outline of a hide to more clearly illustrate the operation of the finishing-rolls.

In the present instance two finishing-rolls A A are shown, which in practice are and may be substituted for the putting-out rolls shown in the Patent No. 444,173, above referred to, and the machine thus changed may be used for finishing the operation on the hide or skin performed by the putting-out machine.

The finishing-rolls A A are of like construction, and each roll is provided on its periphery with two sets of spirally-arranged vanes, blades, flanges, or threads to a, extended from a transverse line or plane through the roll toward-its opposite ends, but at different angles with relation to said transverse line or plane.

The transverse line or plane referred to in the present instance is located substantially one-third the length of the roll from one end of the same, the long vanes a being substantially twice as long as the short vanes a. The transverse line or plane through the finishingroll corresponds substantially to the line 00 00, Fig. 3, and the long vanes a act on the body portion 2 of the hide or skin, while the short vanes a act on the shoulders and neck portion 3 of the hide or skin, but the stretching action of the short vanes a is at a different angle from the long vanes a, and this action of the finishing-roll 011 the hide or skin may be better understood by supposing that the long vanes a stretch the body portion of the hide or skin in the direction indicated by the arrow 20, Fig. 3, and that the short vanes a stretch the shoulders and neck portion in the direction indicated by the arrow 22.

The long vanes a, it will be noticed, wind about the roll and have less pitch than the short vanes a.

It will be understood that the vanes not only are to lengthen the hide or skin, but are to widen at the same time.

It will be noticed that in the finishing-roll herein shown each long vane or blade at has its co-operating short vane or blade (1,, so that the two vanes or blades approximate one continuous Vane or blade extended from end to end of the roll, but in opposite directions from a transverse plane or line through the roll and in dififent angles with respect to said plane and to each other, which is the construction I prefer to use.

p I claim- 1. A finishing roll provided with two sets of vanes or blades extended in opposite directions from a transverse line or plane through the roll and at different angles thereto and to each other, for the purpose specified.

2. A finishing roll provided with the long vanes a and with the shorter vanes a extended in opposite directions at diiferent angles, the long vanes being located on one side of a transverse line through the roll, and the short vanes being located on the other side of said transverse line, and each long vane having its co-operating short vane, substantially as and for the purpose specified.

8. A finishing roll provided with two sets of vanes or blades extended in opposite directions from a transverse line or plane through the roll, one set of vanes having a diiterent pitch from the otherset of vanes, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. V

IRA VAUGHN.
