UNITED STA E PATENT OFFICE.
NATHANIEL F. SNOW, OF SALEM, MASSACHUSETTS.
IMPROVEMENT IN MACHINES FOR SCOURING LEATHER.
Specification forming part of Letters Patent No. 131,831, dated October 1, 1872.
To all whom it may concern:
Be it known that I, NATHANIEL F. SNow,
of Salem, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Scourlng Leather,
of which the following is a specification:
My invention relates to an improved machine for scouring leather; and it consists in the employment of a cylinder which has the ribs or scouring-faces cast as a part of the cylinder, F forming one piece of metal, so that the use of separate stones is dispensed with; and it fur= ther consists in hanging the cylinder at one end of a horizontal frame, which is mounted onan axis, and arranged to be raised or lowered for working-the leather.
In the drawing, Figure l represents a plan view, and Fig. 2 a sectional elevation on line a b of Fig. 1. r
inder. U G are brushes, which may be placed in the recesses between the ribs B. The cylinderis mounted on the shaft 0, and arranged with suitablepulleys (1 cl, for driving it. It is hung in the frame D. Theframe D is mounted on a shaft, E, which also carries the pulleys d d, and is so arranged as to be balanced, or
raised and lowered, through the lever F, which, by being pressed down by the foot of the attendant, raises the opposite end of the frame D, and depresses the cylinder onto the leather, which is placed on the bed G. When the cylinder is not in use it is raised out'of contact with the bed by the spring H. The space between the cylinder and the bed is adjusted by arranging that portion of the bed against which the cylinder bears upon a hinge, so that it may be raised or lowered by the screw K.
In machines of this class the cylinder is usually provided with separate scouring-stones, which are attached to the cylinder. These .stonesare liable to break or become detached.
I obviate the necessity for using separate scouring-faces by the method of constructing the cylinder above described. y
I am aware of the various Letters Patent granted to Havemayer and Berdon in 1870, and I make no claim to the devices shown in the scouring-machines forming the subject of the aforesaid patents.
I claim as my invention- In machines for scouring leather, the scouring-cylinder A, having the ribs or scouringfaces B cast or formed as a part of the cylinder A, and mounted in the frame D, which is arranged so as to be elevated and depressed, in the manner substantially as described and shown.
