TIMOTHY C(CHAIIK, OF PAVTUOKET, RHODE ISLAND.

OIL-CAN.

SPECIFICATION formingpart of Letters Patent No. 286,588, dated October 16, 1883. Application filed July 3,1882. (No modeL) I To all whom it may concern Be it known that I, TIMOTHY C. CHALK, of

- Pawtucket, in the county of Providence and State of Rhode Island, have invented a new the can, by which an air-inlet is provided, as

will be more fully set'forth hereinafter.

The drawing represents my improved oilcan in section, showing its construction and the arrangement of the tubes.

In the drawing, 'A is the body or oil-chamber of the oil-can. B is the dischargetube. G is the air-tube, extending from the top of 1 the can through the body and through the false bottomD into the space between the false bottom D and the spring-bottom d. E is a larger tube, extendin g from the false bottom D to the upper part of the body of-the can. This tube E is open at both ends, the upper end terminating below and to one side of the discharge-tube B.

The operation of the oil-can is as follows: When it is to be used, the air will flow down the small tube 0 into the chamber between the two bottoms, and up the larger tube E into i the can-body or oil-chamber, thus allowing the oil to flow from the can as fast as the air enters the small tube 0; and if this flow of oil is to be momentarily increased, or the oil squirted from the discharge, a sudden pressure exerted on the bottomd will force a quantity of air suddenly into the oil-vessel and expel an equal quantity of oil forcibly.

By the use of the double bottom, the can is materially strengthened, and the airspace between the two bottoms acts, when suddenly compressed, as a bulb in a syringe, and forces the air intothe oil-vessel suddenly. When properly used, no oil will enter the space between the two bottoms, and the air-tubes are notas ing-can with an air-chamber fitted with open tubes, one of which communicates with the exterior of the can, while the other communicates with the interior of the discharge or o1ling nozzle at a point above the top of the cana body.

Iam also aware that oiling-cans having at the bottom an air-chamber which communicates with the exterior of the can and with the;

oil-chamber by means of two tubes arranged in line with the oiling-nozzle have heretofore been known. These forms are, in my opinion, objectionable, for the reason that when the bottom of the can is pressed upon in the operation of oiling, a jet of air is forced directly into the oiling-nozzle or delivery-tube, and tends to ej ectthe oil from said nozzle in a spray. 1

Having thus described my invention, I cl-aim as new and desire to secure by Letters Patent The combination, with the oiling-vessel A, having the discharge-tube B, the two bottoms D and d, forming an air-chamber, and the tube 0, extending from the exterior of the can v to the air-chamber, of the tube E, extending upward from the air-chamber and terminating at a point to one side of the inner end of the discharge-tube, substantially as described.
