UNITED STATES PATENT OFFICE.

PETER BREEN, OF CINCINNATI, OHIO, ASSIGNOR OF ON E-HALF TO LEWIS M. HOSEA, OF SAME PLACE.

LUBRICATOR FOR LOOSE PULLEYS.

SPECIFICATION forming part of Letters Patent-No. 271,193, dated January Application filed December 6, 1882. (No model.)

To all whom it may concern;

Be it known that I, PETER BREEN, a citizen of the United States, residing at Cincinnati, Ohio, have invented new and useful Improvements in Oiling Devices for Loose Pulleys, of which the following is a specification.

My invention relates to a device for oiling loose pulleys used on shafting in connection with pulleys for transmitting power in machincry of various kinds; and it consists in a loose non-rotatin g collararran ged upon the revolving shaft adjacent to the loose-pulley hub, carrying an oil-cup, and perforated or recessed for the passage and distribution of oil to the ad- 1 jacent pulley, and alsoin the construction and arrangement of the collar for the purpose indicated.

My invention is embodied in mechanism illustrated in the accompanying drawings, in which Figure 1 is an edge elevation of the fixed and loose pulleys, with the oiling device and their shaft-mountings. Fig. 2 is a side elevation of the same. Fig. 3 is an axial section of the parts as exhibited in Fig. 1. Fig. 4 is a side elevation of the oiling-collar detached and enlarged, and Fig. 5 is a similar view of a modified form of construction.

In the drawings, A B designate fixed and loose pulleys, respectively, mounted upon a line-shaft, G, revolving in hangers D, suspended from a beam or rafter, E, of the establishment where employed. The difficulty of keeping the shaft properly lubricated in relation to the loose pulley under these circum- 5 stances is well known. Where the pulley is upon a driven shaft the ordinary oil-cup attached to the hub of the pulley and revolving with it would fail to feed by reason of centrifugal force, and where the pulley is upon-the driving-shaft and at rest when the driven machine is out of use the ordinary oil-cup is impracticable, because it requires for its action a position above the surface to be lubricated, in order that the oil may flow downward by gravity, which position cannot, of course, be maintained under such circumstances.

My invention seeks to obviate these difficuL ties and provides a simple and effective device for keeping the parts at all times properly lubricated; and it consists in a collar, F, hearing an oil-cup, G, as shown. The collar is perforated radially for the insertion of the oil-cup, and is further provided with a lateral recess, 9, communicating with the radial perforation,

to assist in distributing the oil toward the side of the loose pulley B, beside which it is placed.

I prefer to construct the collar in two parts, ff, united by bolts in the ordinary manner of such constructions, and extend the lower part, f, laterally into an arm, as shown, which is to be secured, by a rod, h, wire, or in any other manner, to the ceiling-beam, floor, or any other fixed object and prevent rotation. The collar is placed upon the shaft alongside of the loose pulley, and secured laterally by a pin or collar, b, fixed to the shaft. In such position and thus secured the oil feeds downward by gravity from the oil-cup G, and distributes itself by capillary attraction between the sliding surfaces. 7

In the modification shownin Fig. 5 a weight, w, hung to a depending arm or cast therewith, is employed,instead of securing the collar to a fixed object, to prevent rotation; but I prefer the first-described arrangement. 7 5

Instead of attaching a separate oil-cup, as shown, the upper niembenf, may be cast with an oil-receptacle as part of its structure, as an ordinary cap for journal-bearings. As a further modification, the arm f may be also extended out on the opposite side, making two arms, which may then be held by wires from a fixed object to prevent rotation of the collar.

I claim as my invention and desire to secure by Letters Patent- 1. The oiling device for loose pulleys, consistin g of a loose non-rotating collar arranged upon the shaft adjacent to the loose pulley, but independently thereof, carrying an oil-cup, and perforated for the distribution of the oil to the shaft and adjacentpulley, substantially as set forth. 7

2. In combination with the loose pulley B, the collar F, arranged upon the shaft, as shown, carrying an oil-cup, G, and provided 5 with an arm,f, androd h, to prevent its rotation, substantially as and for the purpose specilied.

3. The collar F, composed of the two parts, f f, the latter extended, as shown, and for the [O0 purpose specified.

In testimony whereofI have hereunto set my hand in the presence of two subscribing witnesses.

PETER BREEN.
