FERDINAND LEHR, OF NEW YORK, N. Y.

IMPROVEMENT IN OILERS.

Specification forming part of Letters Patent No. 155,321, dated September 22, 1874; application filed August 19, 1874.

To all whom it may concern:

Be it known that I, FERDINAND LEHR, of the city of New York, in the county and State of New York, have invented certain Improve ments in Oilers, of which the following is a specification My invention relates to certain improve- -ments in that class of oilers which yield their oil by pressing their bottom or sides inward. The object of my invention is to provide an oiler from which the air can escape, when its volume is increased by expansion, to prevent the oil from being forced out through the nozzle, and, also, into which fresh air may be admitted to take the place of the oil forced out of the oiler when used; and it consists, first, in the combination of a discharge-pipe terminating below the level of the oil, with an air-supply opening in the oiler above the level of the oil, said opening being so placed that it will necessarily be closed by the thumb or finger of the operator when using the oiler; second, in the combination, with an oiler constructed as above described, of a stop, in combination with the screw-plug which closes the oiler, to prevent the bottom or sides from being pressed too far inward and guard against too great a discharge of the oil; and, third, in an improved device for admitting the air to the oiler, which serves as a stop to prevent undue compression, and which will prevent the escape of oil when the oiler is accidentally upset, as will be hereinafter described and set forth.

In the drawings, Figure 1 represents a sectional view of my oiler, showing the air-opening through the upper side of the same. Fig. 2 represents a sectional view of an oiler, showing a modification of my invention, in which the air is admitted from the bottom or under side through a tube, which also serves as a stop. Fig. 3 shows a modification of the oiler, provided with a stop, and having the air-aperture on the upper side; and Figs. 4 and 5 show modifications of the oiler, showing various ways of arranging the discharge tubes or nozzles in combination with the same.

A represents the discharge tube or nozzle extending into the oiler, and terminating in such a position that it will fall below the level of the oil in the oiler when the same is being used. In Fig. l the tube A is shown extending into the oiler, and bent upward, so that it will be above the level of the oil when the oiler is not in use; but in using the oiler it is inverted, so as to bring the end of said tube below the level of the oil. The position of the tube A in the remaining figures is naturally below the level of the oil, as it will be perceived. B represents the oiler, which is a disk-shaped metallic vessel with flexible sides that may be readily pressed. inward. At the center of one of the sides is made an aperture, 0, provided with a screw-cap, through which aperture the oiler is filled. The airaperture E, in the modifications shown in Figs. 1, 3, 4, and 5, is made through the said screw-cap D, which forms a bearing upon which the thumb or fingers must necessarily rest in compressing the sides of the oiler, as will be perceived, and consequently the aperture E will be naturally closed in the act of using said oiler. In Fig. 3 the screw-cap is represented extending into the oiler and terminating near the lower side of the same, its end being provided with a stop, F, consisting of a screw, which may be adjusted so as to regulate the extent to which the sides may be compressed, the air aperture E extending downward and through one side of said cap into the oiler, as shown.

In modification shown in Fig. 4 the air-aperture is made through the bottom or lower side of the oiler, and communicates with the interior of the oiler through a passage formedin the stop F attached to said side or bottom. Said stop extends upward into a recess in the screw-cap D, as shown, but at sufficient distance from the top of said recess to allow the air to be freely admittedto the oiler. As thus constructed, it will be impossible for the oil to escape through the air-aperture, no matter what may be the position of the oiler, as will be readily perceived. In using this modification of the oiler, the thumb or finger, in pressing the sides together, naturally seeks the center of the same and, of course, closes the aperture at the moment the oil is discharged.

In all the modifications the aperture E remains open while the oiler is not in use, permitting free ingress and egress of air.

What I claim is 1. The combination of the discharge-pipe A, terminating below the level of the oil, with an air-supply opening through the center of the oiler above the level of the oil in the same, and in such position that it will be necessarily closed in using the oiler, all constructed as herein shown and described.

2. In combination with an oiler constructed as described, the stop F, to limit the amount of compression given to the same, to operate, in connection with the screw-cap O, substantially as set forth.

' 3. The combination of the hollow stop F secured to the bottom or lower side of the oiler, serving as an air-passage for-supplying air to the oiler, and to prevent the escape of oil when the same is upset, as herein described.

In testimony that Iclaim the foregoing I have hereunto set my hand and seal this 14th day of August 1874.
