SPECIFICATION forming part of Letters Patent No. 595,725, dated December 21, 1897.

Application tiled December 9, 1896. Serial No. 615,038. (No model.)

T0 all whom t may concern:

Beit known that I, J AMES MCGINLEY, a citizen of the United States, residing at Kingston, in the county of Luzerne and State of Pennsylvania, have invented new and useful Improvements in Oilers, of which the following is a specification.

My invention relates to a new and useful improvement in oilers for reciprocating or rotary machinery, and has for its object to provide a simple, cheap, and efficient device which will deliver a given quantity of lubricant to a bearing without the possibility of permitting waste of the lubricating agent and which will cease to feed whenthe machinery or part thereof to which the oiler is attached ceases to move.

With these ends in view this invention con-- sists in the details of construction and combination of elements hereinafter set forth and then specifically designatedby the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the Same, its construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in whichy Figure lis a central section of an oiler made in accordance with my improvement; Fig. 2, a similar view taken at right angles to Fig. l, and Fig. 3 a detail side elevation of the feed-plug valve and pendulum.

In carrying out my invention as here shown, 'A represents the cup, which is of suflicient size to hold the desired amount of lubricant, and this cup is provided with a cap or cover B, threaded upon the upper endl thereof in order to close the same, and a shank C is formed upon the bottom of the cup and is threaded in order that it may be secured to the movable part of the machinery to be oiled. This shank has, an opening formed therethrough, which is internally threaded for the reception of the plug D, the latter being correspondingly threaded and having formed thereon a head E, to which is fitted a valve F.

A passage G runs from the lower end of the plug and intersects the seat of the valve,which is also intersected by the passages H and I, the latter of which opens upon the under side of the head in order that it may enter the cup at the extreme bottom thereof, while the former stands at some distance from the bottom of the cup, for the purpose hereinafter set forth. Through the valve is formed a passage J, so arranged that when the valve is in the position shown in Fig. 2 one end of this passage registers with the passage H, while the opposite end registers with the passage I, and when in this position a lubricating agent will enter the passage I and, flowing upward, gain access to the passage J, the passage H serving as a vent to permit the inflowing of the oil to the passage J.

L represents a pendulum which is secured within one end of the valve and has at its upper end a weight M, and this pendulum is limited in its swinging movements by the shoulders N, formed in the head of the plug, from which it is obvious that when the oiler is secured to a reciprocating member of a machine, such as the cross-head of an engine, the pendulum will be caused to swing first to one limit of its movement and then to the other by the inertia thereof when the direction of the moving member is changed-as, for instance, the pendulum would remain in the position shown in f ull lines in Fig. 2 so long as the oiler was moved in the direction of the arrow, but upon this movement being reversed the inertia of the pendulum would cause it to swing to the position shown in dotted lines of this figure, where it would remain until the movement was again reversed. These operations would first bring the passage J into alinement with the passages 'H and I, when it would be fllled with the lubricating agent, and when the pendulum was swung to the position shown in dotted lines one end of the passage J would be carried through alinement with the passage D, thus permitting the lubricant to flow through the vlast-named passage to the bearing, and so long as the valve remains in this position no more oil can gain access to the valve, since the valve will cut off the iiow thereof. By this arrangement it will be seen that a given amount of oil will be delivered to the bearing for every to-and-fro stroke of the moving member of the machine, and by no possibility IOO cana greater amount of oil gain access to the bearing, thus precluding the possibility of waste.

The advantages of my improved construction due to the slanting of passage I are as follows: The passage .I is caused to fill more rapidly than. if the passage-ways I H were horizontal, the pendulum need not swing at so great au angle, and the cup is caused to be drained to the bottom.

For convenience in assembling the oiler the head of the plug is slotted, as indicated at O, for the reception of a screw-driver, whereby the plug may be run into the place or Withdrawn from the cup when occasion requires.

I have here shown a Washer I interposed between the cover and upper edge of the cup to serve as a packing forseeurely closing the cup, and this is advantageous when the device is to be used in connection with rotary machinery, such as a loose pulley, in which case the cup would, during certain portions of its movement, be inverted, and when so used the pendulum will be caused to swing in one direction when moving upward and in the opposite direction when moving downward, thus opening and closing the valve to bring about the desired results.

Having thus fully described my invention, what I claim as new and useful is- In a device of the character described, a cup, a plug tted therein having a Vertical passage, a valve seated in the passage-Way, said valve and plug having an inclined passageway therethrough leadin g from the bottom of the cup, a flange on one end of the Valve and a pendulum on the other end of the valve adapted to reciprocate Within a slot of the plug and be limited in its movement by striking the Walls of said slot, as and for the purpose described.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribin g witnesses.

JAMES MCGINLEY.
