4application led September 5, 1922. Serial No. 58692.
To all whom t may concern.'
Be it known that I, WniLIAM A. SMITH, a citizen of the United States of America, residing at Detroit, in the county of Wayne 5 and State of Michigan, have invented certain new and useful Improvements in Oilers for Pneumatic Tools, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to oilers of 'the type. which is applicable for lubricating the working y parts of fluid operated mechanisms wherein it is necessary to overcome the fluid pressure in order to introduce the lubricant. ln oilers of this type it is necessary to provide some means to prevent the escape of duid pressure while the lubricant is being introduced.
lDuring the operation of pneumatic tools it is important that the working parts be lubricated frequently but the operators often neglect this duty because it interferes with their production output. It is therefore vimportant to provide an oiler which is simpleto manipulate and which can be conveniently carried.
ln my improved construction l have pro- .vided a compact device which is' adapted to be carried by the operator in his pocket and which can be manipulated very simply while the tool is in operation. ln general construction there is a casing containing an oil reservoir on which is mounted a plunger pump connected to an ejecting nozzle which is provided with a conical tip adapted to seat in a itting upon the tool to be lubricated. The eectlve area of the plunger pump is made considerably greater than the area of 'the nozzle tip so that the pressure applied to the plunger for forcing the lubricant into the fitting is greater than the back 'pressure exerted by the operating fluid upon the nozzle whereby an edective seal is maintained between the nozzle and the fitting.
ln the drawings: v Fig: l is an elevation of the improved oiler;
Fig. 2 is a cross section of the same with the plunger in rearward position;
llig, 3, is a similar section with the plunger forward showing the nozzle engaging the tool to be lubricated;
Fig. 4; is an end elevation.
In my preferred construction A represents a substantially rectangular container having 'communicates through a passage l11 with the lower portion of the chamber. of the container and also communicates at its forward end with the nozzle tube G which is secured to the 'casing at G', The outer end of the nozzle has a'tapering conical surface H and the nozzle is also provided with a longitudinal bore G2 for the passage of the lubricant. Between the nozzle and the cylinder is a check valve l 'consistin preferably of the ball l' which is norma' y held in engagement with the conical seat l2 by means of a spring ls which abuts against the inner end G3 of the nozzle tube. J is a detachable plug or cap preferably located in the base of the casing .for lling the chamber with lubricant.
M represents a portion of a tool to be lubricated such as a pneumatically operated drill which is provided with a ttin K in threaded engagement therewith. T e fit-- ting is recessed to form a conical seat K which is adapted to fit tihevconical surface H of the nozzle and form a seal therewith when pressure is applied upon the plunger pump. The tting is also provided with an axial bore N, which extends therethrough and forms a conical seat N for the check valve L which is normally held in engagement'with the seat by the spring L. y
The cross sectional area of the piston is made considerably larger than the opening K in the fitting so that in the operation of the device it is only necessary to place the nozzle. in the fitting and reciprocate the plunger by means of the handle D. Sudicient pressure must be exerted upon the handle to build up a pressure in the c lieder equal to the fluid pressure in the tu e, but because of the relatively large area of the piston the pressure of the nozzle upon the iitting will be greatly in excess of the back pressure in the tube thereby formin `an effeet-ive seal and preventing any lea age at this point.
Thus it will be seen that l have provided a very simple construction which may be conveniently carried by the operator and which may be used for the lubrication of a pneumatic tool by simply placing the nozzle in a iitting upon the tool and operating the pump handle.
lfVhat I claim as my invention is:
An oiler for pneumatic tools comprising a lubricant container adapted to be carried in the operators pocket, a nozzle secured thereto having its outer end adapted 'to seat in Ia fitting, a cylinder, a manually operable plunger in said cylinder, a check valve between said cylinder and nozzle, a valveless inlet port in said cylinder overrun by said nsoaoee piston .and communicating with said container, resilient means for normally holding said plunger in a position to seal said inlet port, and a handle for reciprocating said plunger to eject the lubricant, the nozzle forming a seal with the fitting by the pressure exerted upon said plunger during its ejecting stroke, the cross-sectional areas of the piston and the nozzle being so proportioned as to provide for the ejection of the lubricant through the nozzle with suicient force to overcome the fluid or line pressure of the tool.
In testimony whereof I affix my si nature.
WILLIAM A. Sli 1TH.
