OILING DEVICE.

To all whom it may concern:

Be it known that I, J 011x MAnnox, a citizen of the United States, residing at. Jamestown, Chautauqua county, New York, have invented certain new and useful. Improvements in Oiling Devices; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to devices particularly designed for use in supplying oil to overhead journals or oil cups, the objects of the invention being to provide a simple, cheap and efficient device which may be manipulated to inject the proper quantity of oil into the ournal box or oil cup while the attendant or machinist remains on the fioor below the journal or part to be oiled.

The invention consists in certain novel details of construction and combinations and arrangements of parts, all as will be now described and pointed out particularly in the appended claims.

Referring to the accompanying drawings: Figure 1 is a side elevation of an oiling device embodying the present improvements, the staff or handle being broken away to show that it may bemade of any desired length. Fig. 2 is a section on a vertical plane showing the internal construction of the oil receptacle and pump for ejecting the oil therefrom.

Similar letters of reference in both figures indicate the same parts.

In carrying the invention into practice, a stafi or handle A of the desired length is provided and upon its upper end is mounted a head or light metallic frame B, preferably having a socket b for the reception of the end of the staff, a bracket 6 upon which the oil can or receptacle may seat, and two brackets or bearings 72 in which the cylindrical pump barrel C is mounted so as to be capable of a longitudinal movement. The oil can or receptacle Dgnay be of any usual commercial type, but preferably has a cylindrical body to facilitate the application of a clamping band or ring E, which retains the can body in place on the frame. The clamping ring may be conveniently held by a bolt c, and the spout of the can is preferabl curved at (Z, so that the oil ejected therefrom will be directed downwardly into the top of a journal box or cup. A continuation Specification of Letters Patent.

of the spout or nozzle of the can, lettered d in Fig. 2, extends downwardly to a point in proximity to the bottom of the can, whereby the entrance end of the spout is kept below the oil level until the latter is practically all discharged.

For discharging or ejecting oil from the can, provision is made for creating an air pressure in the upper portion of the can and for this purpose the discharge duct 0 of the air pump a flexible tube in the present instance is put into communication with the can, preferably at or near its upper end, and in order that the cost of the device may be reduced and use made of stock materials in its product-ion, the said pump is conveniently an ordinary hand bicycle pump, the upper end of the piston rod C being held by a fixed bracket C and a coiled spring C being mounted on said rod for returning the pump barrel to its normal position after it has been advanced to force air into the can.

As a convenient and preferred means for operating the pump, the head or frame B is provided with a pump operating lever F adapted to cooperate with the end of the pump barrel and to be itself operated by a wire or flexible connection Gr, extending from its opposite end longitudinally through a groove a in the handle or staff to a hand lever H, pivotally mounted on the staff near its lower end in convenient position to be grasped by the hand of the operator and to be oscillated by the fingers of the same hand which supports and manipulates the device. The operating handle for the purpose mentioned has its hand engaging portion movable toward and from the end of the staff, thus by grasping the staff and operating lever in one hand the pump may be readily manipulated to force air into the can, thereby creating a suificient pressure over the oil to discharge the latter through the spout.

The device of the present invention, it will be noted, is exceedingly simple; the head or frame is a casting of aluminum or other metal, and the oil can and pump may be of ordinary construction now found on the market, while the assembling of the parts does not call for the exercise of any special skill, thus the device may be marketed at a very low price.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is:

1. In an oiling device, the combination with the staff having a pump operating hand lever at its lower end and a metallic frame mounted on its upper end, of can and pump supporting brackets formed on said frame, an oil can having a downwardly opening discharge spout and mounted on said can bracket, an air pump mounted in the pump bracket and communicating with the upper portion of the can, a pump operating lever pivotally mounted on the frame, and a connection between the said levers and whereby the pump may be manipulated to create an air pressure in the can for discharging the oil.

2. In an oiling device, the combination with the shaft having the pump operating hand lever at the lower end, and a head or frame mounted on its upper end, an oil can carried by said head and having a discharge spout provided with an entrance opening near the bottom of the can, an air pump having a movable barrel mounted on the head and communicating with the upper portion of'the can and connections between said pump barrel and hand lever for manipulating the barrel to create air pressure above the oil in the can to discharge the oil.

3. In an oiling device, the combination with the staff having the pump operating hand lever at the lower end, ahead or frame having the socket for the upper end of the staff and brackets for an oil can and pump respectively, of an oil can mounted on the can bracket, a clamping ring for securing said can in position, an upwardly extending downwardly opening discharge spout for the can having its entrance aperture near thev bottom of the can, anair pump having a vertically movable barrel mounted in the pump brackets and having its discharge aperture communicating with the top of the oil can, an operating lever pivotally mounted on the head above said socket and in position to engage the lower end of the air pump barrel, and a connection between said operating levers whereby the barrel may be manipulated to create an air pressure above the latter for the discharge of the oil; substantially as described.

4. In an oiling device, the combination with the staff having the pump operating h and lever at its lower end, the head 01' frame at its upper end and the brackets on said head or frame, of the oil can mounted on said head or frame, the pump barrel movably mounted in the brackets, the piston rod for said pump, a fixed connection between the piston rod and head, a flexible connection between the pump discharge and oil can, a spring for returning the pump barrel to normal position, an operating lever pivotally mounted on the head or frame, and a connection between said operating levers, whereby the pump barrel may be manipulated to create a pressure within the can; substantially as described.
