HAND-olLER.

SPECIFICATION forming part of Letters Patent No. 274,683, dated March 27, 1883.

Application led November 1], 1882. (No model.)

T o alt whom it may concern:

Be it known that we, CHARLES WELDY and GEORGE WITMAN, citizens of Ythe United States, residing at thecity of Beading, county of Berks, andState of Pennsylvania, have invented certain new and useful Improvements in Hand-Oilers, of which thefollowing isa specification. i Our invention relates to improvements in hand-Oilers adapted to the use of engineers, machinists, and others; and the object is to supply a want for a simple, reliable, and cheap oiler. This we attain by' adding to the rod of the usual plunger-spout oiler a threaded reenforce of about one-half the length of thev spiral spring used thereon, and upon which a milled-head nut freely works.

Referring to the drawings herewith, which form part of this specification, Figure l represents an exterior elevation of our improved oiler. Fig. 2 represents a sectional elevation, showing the interiorV arrangement. Fig. 3 is y a plan showing in dotted lines the guide for vthe rod; Fig. 4, detailof plunger-rod This `cross-piece is 'placed so as to :fall between the handle and the filling-tube A3. Immediatelyin'front ofthe handle A5 is soldered upon the cone A a perforated guide-piece, A", through which the plungergrod is led out of the can.

D is the plunger-rod., having at its upper end a leather piston, F, ttin g the interior of the spout at the intersection of B2 with the same. Midway between the plunger F and the cross-bar G a threaded re-enforce, D', is soldered to the rod, having a milled nut, E, working freely on the same. The rod after passing through the cross-bar is bent twice at' rightangles toward the piston F, the distance between the bends corresponding with the distance between the centers of the can and guidepiece A4. A spiral spring, g, occupies the space between the cross-piece C and the milled nut E, while the short protrude'd end is protected by a thumb cap piece, H.

We do not confine ourselves to the form 4of can shown, as the improvement may be applied to any of the usual oiler. nozzle-cans.

In constructing the cans the cross-piece G is soldered or secured in place in the interior of the cone or top, and the guidepiece A4 upon the exterior of the cone or top. Thebent plunger-rod is passed through the cross-piece and its terminaljbend through the guide-piece. rEhe re-enforce D is then secured upon the rod at the proper place, and the spiral spring q` is placed over the rod uponthe cross-bar C and the milled nut screwed down upon the Vsame', which secures it in place, andthe extreme end is crowned with the plunger F, of leather or elastic material. The cone or top Ais now soldered or secured to the body A.. The length of the rod D is so adjusted that the plunger F shall lie in close proximity with the junction of B and B2.

The voperation of the oileris as follows: The can is filled through the filling-tube A3. Then faking the can by the handle A5, with one fin-` ger resting upon the cap H, the spout is placed over the hole or place to be oiled and the cap pressed down. This compresses the spring g and withdraws the plunger F away from its seat into a wider portion of the taper spout, and the oil or lubricating material passes around the same and out of the end of spout B2. moment the pressure 4on the cap is relieved the spring expands and the dow of oil is cut off. Sufficient air passes the rod D into the can throughthe guide-piece A1 to balance the column and permit a steady flow of oil as long as the cap His pressed down. Should the spring become weak, the spout is unscrewed and the milled nut screwed farther down upon the reenforce, and in case of failure of spring anew one may be placed in position, winding it over the rod until it surrounds the salme.

In all the oilers of which we have knowledge, where the spout was closed by an automatic piston, plunger, or valve, the springs would in time clog and become. inoperative, and there being no provision for repairs or' renewal the cans were thrown away. By our improvement the life ofthe can is extended, and the cer- The 2. In an oiler, as described, a centrally-per"- forated cross-bar, O, in combination with the 15 oiler A A', plunger-rod D, springg, 11e-enforce and nut D E, and guide-piece A, substantially as and .for the'purpcsey specified.
