LUBRICATOR.

Specification of Letters Patent.

Patented June 7, 1910.

Application filed April 22, 1909. Serial N0. 491,588.

To all whom it may concern.'

Be it known that I, PETER J. SWEENEY, a citizen of the United States of America, residing at Windsor, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Lubricators, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates particularly to a novel type of lubricator, especially designed for lubricating the pistons of explosion engines, and consists in the construction of the lubricator, in the arrangement and combination of its parts, and in certain details of construction as will be more fully hereinafter set forth.

In the drawings, Figure 1 is a view in elevation of a lubricator embodying my invention; Fig. 2 is a similar view, partly in section; and Figs. 3 and 4L are enlarged perspective views of some of the lubricator parts detached.

The primary object of the invention is to provide a lubricator that may be applied to the explosion chamber of an engine or m0- tor, and in which the oil feed will not be interrupted by the explosion. With this object in view, I have constructed the lubricator with a check-valve for controlling its discharge passage, and with a baffle serving to deflect such of the explosion gases as are not checked by the valve away from the feeding device. I have also preferably constructed the lubricator in such manner that the baille in deflecting the gases will assist the valve to close, thereby reducing to a minimum the amount 0f lexplosion gases that may enter the discharge passage.

Referring to the drawings, the referenceletter A designates the reservoir or oil cup of the lubricator, B the usual sight feed chamber, C the feed tube, and D the discharge passage formed in the externally threaded nipple E, preferably made integral with the wall of the chamber described.

F represents the check-valve controlling the discharge passage, Gr is a bailie member arranged within the chamber over the inlet end of the passage, and I-I is preferably a rigid connection between the parts.

I designates the cylinder, formed preferably with an internally threaded apertured boss J adapted to receive the nipple E of the lubricator, and K is the piston to be lubricated.

Assuming that the lubricator is applied to the explosion chamber of the cylinder and the parts to be in position as indicated in Fig. 2, when the explosion takes place the valve F will be raised and will engage its seat a, and such amount of explosion gases as may enter the discharge passage before the valve closes will strike against the baffle, thereby assisting the closing of the valve, and will be deflected to the walls of the sight chamber away from the tube C so as not to interfere with the feed. Upon the return- 1 stroke of the piston the valve will leave its seat automatically through the action of gravity, allowing the lubricant to pass within the cylinder in the desired manner.

To render the baiiie member more effective, I preferably form the same in the shape of an inverted cup, as shown, the depending wall of which prevents escape laterally of the explosion gases, compelling them to pass downwardly and to strike against the bottom of the chamber. This form of baffle is also more effective, for obvious reasons, in assisting the operation of the valve, causing the same to close more rapidly than where the action of the eXplosion gases is upon the valve only.

Any suitable construct-ion of valve and bafliev may be employed, but I have here shown the preferable construction, the valve being formed by the head of a screw-bolt L, the shank of which has a threaded engagement with the baflie and to retain the parts in their xed relation to one another I preferably turn over the upper end of the screw, as at b, after the parts are assembled.

While the lubricator described is especially designed for application to the explosion chamber of the cylinder, it may be applied to other parts thereof wherein ,the feed will not be affected by the explosion except by slight leakage. In such instances the valve would be normally away from its seat and the baffle would Acontact with the chamber wall. 'Io permit the lubricator to feed properly under such conditions, I form a number of lateral ports, as c, in the lower portion of the bafiie, preferably its lower edge, which allows the oil from the tube to enter within the discharge passage andfeed constantly therethrough.

What I claim as my invention is,-`

l. In a lubricator, the combination with a reservoir provided with a sight feed chamber and a discharge passage leading therefrom, of a check valve controlling the passage, a movable baffle member within the chamber comprising an inverted and later ally ported cup-shaped member arranged over the pasage inlet, and a rigid connection between the baille member and valve.

2. In a lubricator, the combination with a reservoir provided with a sight feed chamber and a discharge passage leading there- Jfrom, of a check valve at the lower end of the passage, an inverted and laterally ported cup-shaped baille arranged within the chamber over the upper end of the passage, and a rigid connection between said batlie and valve extending through the passage.

3. In a lubricator, the combination with a reservoir provided with a sight-feed chamber terminating in a threaded nipple, said ber and a discharge passage leading therethrough and the end of said nipple being recessed to form a valve seat, an inverted cup-shaped baille arranged within the chamber over the upper end of the passage, having a plurality of open-ended recesses formed in its edges, a check-valve engaging the valve seat in said nipple, and a member formed integral with the valve extending through the passage in the nipple and forming a rigid connection between the valve and batlie.

,4. In a lubrlcator, the combination with a reservoir provided with a sight feed chamber, of a member forming a portion of the chamber having an opening or aperture forming a discharge passage, a check` valve controlling the passage, a movable baiiie member arranged within the chamber over the passage inlet and adapted to seat upon said apertured member, and a connection between said valve and baiile whereby the latter assists in the closing of the valve, there being a communication between said chamber and the discharge passage in the seated position of the baffle.

5. In a lubricator, the combination with a reservoir provided with a sight feed chamber, of a member forming a portion of the chamber having an opening or aperture forming a discharge passage, a check valve controlling the passage, a movable baille member arranged within the chamber over the passage, a connection between said valve and battle whereby the latter assists in the closing of the valve, the baille member being adapted to seat upon the apertured member, and one of said members being provided with a recess forming a means of communication between said chamberv and the discharge passage in the seated position of the baffle.

In testimony whereof I aliX my signature in presence of two witnesses.
