CYLINDER FOR HIDE-WORKING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 771,614, dated October 4, 1904.

Application filed June 15, 1904:.

1'0 (l/M/ w/wm may concern:

Be it known that I, J AMES WVILLIAM DECK- ERT, leather-splitter, a citizen of the United States, residing in the town of Oakville, in the county of Halton and Province of Ontario, Canada, have invented certain new and useful improvements in Cylinders for Hide-Vvorking Machinery, of which the following is a specification.

My invention relates to improvements in cylinders for hide-working machinery; and the objects of my invention are, first, to provide a substantially new cylinder for each of the different classes of work-such as unhairing, unfleshing, setting, and working out hides and stoning out hides withouthaving to provide an entire new cylinder for these purposes; secondly, to permit of the speedy and easy renewal of any of the blades or stories that may be worn out or damaged; thirdly, to provide a particular construction of blades for unhairing purposes, and, fourthly, to situate part of the blades so as to provide the righthand half of the cylinder with working-out and setting-out spirals that work the hide to the right and to situate the rest of the blades as to provide the left-hand half of said cylinder with the same spirals that work the hide out to the left; and it broadly consists, essentially, of a permanent metal foundation, preferably a shaft, a plurality of sections or rings removably held thereon, and a plurality of blades or stones held in said sections or rings in such manner as to provide a slight working-out spiral and a pronounced setting-out spiral around the cylinder, as hereinafter more particularly explained.

My invention further consists in constructing the blades for unhairing purposes out of rawhide, as hereinafter more particularly explained.

Figure 1 is an enlarged side elevation of part of my cylinder, showing same provided with blades for unhairing purposes. Fig. 2

is a cross-section on the line a b, Fig. 1. Fig. 3 is a side elevation of oneof the working-out blades, and Fig. 4 is an end elevation of same. Fig. 5 is a side elevation of one of the setting-out blades; and Fig. 6, a cross-section on Serial No. 212,672. (No model.)

with blades or stones set at an angle or angles 4 which work the hide out to the right and the other half is provided with blades or stones set at the same angle or angles which work the hide out to the left. In my preferred form of construction I use two kinds of blades for each ring or section and secure same therein at different angles. By securing the work ing-out blades at an angle in each section or ring they make a slight working-out spiral round the cylinder, and by securing the setting-out blades at an angle in each section or ring they make a pronounced setting-out spiral round the cylinder. As will be understood, the Working-out and setting-out spirals in the right-hand half of the cylinder work the hide to the right and the same spirals in the left-hand half work the hide to the left.

A is the permanent metal foundation, preferably a shaft, and same is provided with ends a, designed to be held in any suitable journal-bearing.

B represents the sections or rings designed to be slid onto the shaft A. I do not confine myself to any construction for securing the said sections or rings on said shaft; but my preferred form of construction for this purpose consists of a key C, suitably secured to said shaft, as by screws 0. Each section or ring is provided with a central opening D, preferably round, so as to fit the shaft A, and a keyway E, in which fits the key 0. By this construction it will be understood that the said sections or rings may be easily slid on and off said cylinder and that same will necessarily rotate therewith. scribed, there are a number of these rings or sections held on said shaft, and each is pro- As before dcvided with a plurality of blades or stones held at the required angle therein. I do not confine myself to any particular construction of blade or stone, nor do I confine myself to any particular way of securing same in said sections or rings. Neither do I confine myself to necessarily using sets of blades or stones in said sections or rings, as it will be clearly understood that, for instance in stoning out hides, same kind of stones may be used in the said rings and set at the same angle therein.

For the purpose of illustrating my invention I have shown two diiferent kinds of blades that I prefer to use in unhairing hides. The working-out blades F are secured alternately in the sections or rings and at a slight angle therein, so as to provide a slight working-out spiral round the cylinder, and the intermediate setting-out blades G are secured in said sections or rings at an angle, so as to make a pronounced setting-out spiral round the cylinder. From this, and as before mentioned, it will be seen that by so placing the blades in said sections the working-out and the setting-out spirals in the right-hand half of the cylinder work the hide to the right and the same spirals in the left-hand half work the hide to the left. My preferred form of construction for securing the said blades in place is to provide the sections or rings with dovetailed grooves H and pack therein and around the incased part of said blades any suitable material, such as cement or lead (Z, as shown. The endsf' of the working-out blades F preferably abut the ends g of the settingout blades Gr. As will be clearly seen from the drawings, the ends f and r of said blades extend beyond the sides of the sections or rings, so that the said blades will overlap part of the path of movement of the blades in the adjacent sections or rings.

The working-out blades F are made of rawhide specially prepared and compressed, and consist of a number of pieces It of rawhide placed together, as shown, and riveted by rivets As will be seen from Figs. 1, 2, and 4-, the working edge of said blades F is shown square. By constructing the said blades from rawhide I obtain a lasting edge and a decided grip on the hide, pulling the hair more readily than any blades heretofore designed for that purpose. These blades are also very effective on line hair and for taking out dirt, grease, and lime. The setting-out blades G are also specially prepared and compressed. They consist of a central portion I, made of rawhide, over which is covered the outer portion J, also constructed of rawhide. By any suitable means, such as rivets j, the parts of the blade G are secured together. The working edges of the blades G- are rounded, as shown at O, and has a very excellent effect in setting-out the hide.

As will be seen from the drawings, the preferred staggered positions of the blades F and G in each half of the cylinder essentially make the setting-out and working-out spirals have staggered sections.

I do not confine myself to the construction of the several parts nor to the exact positions of the blades, as changes maybe made therein without departing from the spirit of my invention.
