NITED STATES PATENT OFFICE.
DANIEL BATEMAN, OF PHILADELPHIA, PENNSYLVANIA.
CARD-GRINDING ROLL.
SPECIFICATION forming part of Letters Patent No. 269,821, dated January 2, 1883.
Application filed June 5, 1882.
To all whom it may concern:
Be it known that I, DANIEL BATEnAN, a subject of the Queen of Great Britain and Ireland, and a resident of Philadelphia, Perms lvania, have invented certain Improvements in lard Grinding Rolls, of which the following is a specification.
The object of my invention is to construct a grinding-roll which will grind the teeth ofcardfillets more effectually than those of the ordinary form. This object I attain by providing the roller with annular grooves and making the ridges thus formed of alternately ditl'erent heights.
1n the accompanying drawings, Figure 1 is a view of my improved grinding-roller with devices for imparting to it a traverse motion; Fig. 2, an enlarged view of a part of the roller.
lilyimproved roller may be constructed of any of the well-known materials used in constructing cardgriuding rolls; but I prefer to make it by applying a layer of plastic emery to the surface of a metal cylinder, and I then form on the surface of this emery, while still plastic, annular V-shaped grooves,whose depth will vary according to-the character of the card-teethto be ground. I prefer to make all the grooves of about the same depth, but the ridges I make of different heights, every alternate ridge being about one-sixteenth of an inch higher than the intermediate ones. Instead of forming these ridges -in the plastic emery, they may be formed by turning, and of any suitable material.
(N0 model.)
D, mounted in a bracket, E, in which the shaft A may turn. On the stud of this bracket is formed an eccentric acting on the yoke Gr, carried by the step H, which is fixed to theframe of the machine. As the shalt with its worm F rotates a slow longitudinal reciprocating motion will thus be imparted by the eccentric and yoke to the roller across the face of the cards. I find that by providing the grindingsurface with these alternately high and low V- shaped ridges the teeth of the card, as the roller traverses across the cylinder, will be more effrctually ground than with a grooved roller whose ridges are all of about the same height.
I claim as my invention A card-grinding roller having annular V- shaped grooves, with ridges. of which every alternate one is slightly higher than those intermcdiate, substantially as described.
In testimony whereofI have signed my name to this specification inthe presenceof two subscribing witnesses.
DANL. BATEMAN.
