UNITED STATES PATENT FEICE.
JAMES -NMALOY, OF BOSTON, MASSACHUSETTS.
Specification forming part of Letters Patent No. 58,852, dated October 16, 1866.
To all whom 1't may concern:
Be it known that I, JAMEs W. MALOY, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Machines for Polishing and Finishing Marble, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, inaking a part of this specification, in which- Figure 1 represents a plan view; Fig. 2 longitudinal vertical section, and Fig. 3 transverse section of Fig. 2 on the line a: fr.
Similar letters indicate like parts in the several figures.
My invention consists ot' a longitudinallyreciprocating and interinittently-rotating cylinder formed of one piece, or of a series of collars or disks placed upon a shaft, in connection with an inclined table or plat-forni, which holds the marble or other material to be operated upon.
A in the drawings represents a table, properly supported on legs L. Upon each end of the table is secured a bearing, K. In the bearing, at one end of the table A, is journaled a shaft, O, to which the cylinder B isv attached, the other end of the shaft passing loosely through a sleeve, D, at the other end ofthe table, which sleeve is fitted in a bearing at that end of the table.
The cylinder may be formed of 011e piece, or of a series of collars or disks secured to the `shaft O and revolving with the same.
To one'end of the cylinder B is rigidly attached a metallic grooved shoulder, b, which its upon a forked arm, a, and turns freely in the saine. One end of this shoulder is provided with teeth and serves as a ratchet, 1'.
The arm a is represented as bent at right angles, and, passing downward, is secured to a narrow bar, E, supported in aslot in the crossbar E at the end of the table and a slotted bracket, E, attached to the under surface of the table. The bar E is allowed a free lon gitudinal movement in the said bar and bracket.
To the under side ofv the bar E is attached a slotted link, G, in which is fitted-a wrist of a crank-shaft, which may be operated by hand or other power. The crank-shaft is supported in a hanger, F, attached to the under side of the table.
The sleeve D, which is fitted loosely on the shaft O, is provided with a spiral groove, which fits over a pin in the bearing K, so that in moving longitudinally it will also be partially rotated; To the inner end of the sleeve D is hinged a pawl, p, so that it may be readily thrown in and out of gear with the ratchet 1' on the shoulder b.
Upon one side of the table A is a movable inclined table or platform, H, its lower edge coming in close proximity with the 'cylinder B. This table or platform may be arranged at any desired angle, and supports the material to be operated upon, so that its edge will, by its own weight, bear upon the cylinder B.
The cylinder B may be made of iron or other metal, or of lead or copper having a coating of emery; and in polishing the marble the cylinder may be covered with felt or other similar material.
XVhen the cylinder B is formed of a series of collars or disks, the latter may be moved or interchanged upon the shaft U, in case their surfaces should be worn away more upon one part of the cylinder than upon another.
The operation is as follows: The crank I, being put in motion by any convenient power, imparts to the cylinder B, through the niedium of the slotted link G and forked arm a, a
longitudinal reciprocating motion when the pawl p is not engaged with the ratchet 1' on the shoulder b.
Vhen it is desired to impart to the cylinder B a partially-rotating motion in connection with the longitudinal motion, the pawl p,at tached to the sleeve D, is thrown into gear or connection with the ratchet 1' 011 the shoulder b, which is rigidly connected with the cylinder B; and as the sleeve D is rotated by the pin in the bea-ring K, fitting in the groove in the said sleeve, the pawl p will force the ratchet 1',
and consequently the cylinder B, to move round with the sleeve D to the extent per mitted by the groove in the sleeve, and by continuing the motion of the crank the sleeve D will move in the opposite direction and allow the pawl p to slip over the teeth of the ratchet 1' until the next. forward movement of the sleeve causes the pawl to impart a similar partially-rotating movement to the cylinder B..
that I claim as my invention, and desire' to secure by Letters Patent, is-
1. The reciprocating cylinder B, when conb structed and operating as und for the purpose saine for joint operation, substantially in the described. manner and for the purpose specified.
2. The grooved sleeve D, provided with a. In testimony whereof I have signed my pnwl, p, or its equivalent, as described. name to this specification in the presence of 8. The combination of an inclined table or two subscribing witnesses. platform, H, with the cylinder B, substantially JAMES XV. M ALOY. as described. i
4. The combination of cylinder B, grooved sleeve D, and the menus of connecting,` the Witnesses:
