Description

UNITED STATES GEORGE A. GRAY, JR.,
PATENT OFFICE.
OF HAMILTON, OHIO.
IMPROVEMENT IN MACHINES FOR TURNING PULLEYS.
Speciiication formingl part of Letters Patent No. 1I$S,394, dated April 29, 1873 application tiled. August 20, 1872.
To all whom it may concern:
Beit known that I, GEORGE A. GRAY, Jr., of Hamilton, Butler county, State of Ohio, have invented a certain new and useful Machine for Turning Pulleys, of which the following is a specification:
Natnrc and Objects of Intention.
Description of the Accompanying Drawing.
Figure 1 is a side elevation of my machine with the pulley and driving-dog in section. Fig. 2 is a perspective vewot' the revolvingtable, on which the driving-dog is attached, as shown.
General Description.
A is the bed-plate ofthe machine; B B', the side housings; O, the stationary top rail or brace 5 and D, the vertically-sliding rail. E is a stationary block, similar in construction to the tail-block of a lathe having a sliding center, e, operated by hand-wheel c. This block is attached tothe rail D. F is the revolving driving-table suitably connected by beltin g or otherwise to the driving mechanism of the machine, and having an interior aperture, f, either in itself or a stationary bush for the inl sertion of a center, ff, for the lower end ofthe mandrel G. The mandrel turns between the` centers c f in a manner similar to those which are used to support work between the centers of a lathe, and is fitted snugly to the bored hub of the pulley H. The dog I which is used to drive the pulley is of the following construction: Its Wings i are iitted with drivingstuds J, secured each in one of the series of holes t', the series being provided to enable the studs`to drive diii'erent sizes of pulleys. The wings i" of the dog are secured loosely to the table by bolts K, which pass through elongated holes in the said wings, the slots permitting the dog to have a lateral movement, so as to allow the driving-studs J to adjust themselves to irregularities in the arms of the pul Aley, and thus press with equal pressure upon the opposite arms of the pulley for driving.
The sliding saddles L carry two cutters, M M',
which can be adjusted to any desired angle, so that both may be cutting at the same time, and onebe forming one side'of the crown of the pulley and the other the opposite side, as shown in Fig. 1; or both may be operating together with different depths of cut upon the same side of the crown. The tools have the cross-feed and downfeed peculiar to boringmills.
Ola-im.
The combinatiomin the usual or suitable frame-work of a pulley-turning machine, of revolving table F, tail-block E, self-adjusting Vdriving-dog I J K, and adjustable cutters L
