Description
P aanfed a. 1,; 1929 UNITED STATES PATENT OFFICE HowARD J, MURPHY, or READING, MASSACHUSETTS, AssIGNoR, BY M'EsNE ASSIGN- MENTS, To ALEMITEcoRroRATIoN, or cHIcAGo, ILLINOIS, A CORPORATION or DELAWARE LUBRICATING APIALRATUS g Application filed November 18, 1924. Serial No.Y 750,605.
This invention aims' .to provide `an iniproved detachable nozzle for a lubricant-expelling device.
In the drawings,-which illustrate a prev expelling devices wherein the lubricant can-` n ot be discharged unless the device is connected to a lubricant-receiving nipple. f
, In automobiles, particularly, all the parts thereof that may be lubricated are not equipped with nipples, such for instance, as
' the differential gearing and the transmission l. gearing.4 These gears are. covered by hous-.
ings, which are generally provided with `a small openin for reception of lubricant.
y Ordinaril t e lubricant-expelling device,
used in lu ricating most parts of the car, cannot be used to expel lubricant into these housings and thereforel my invention will be found useful in connection with the lubricant-ex- A3o pelling device of the type mentioned to permit lubricating of all parts of the car including those not equippedwith lubricant-receiving nipples to which the device maybe attached. The nozzle may be quickly and easily `attached to and detached from the discharge end ofthe gun and is so constructed that 1t is strong and durable and can be used l in connection with supplying lubricant through relatively small openings.
My invention, as illustrated, comprises a nozzle having at one end thereof a relatively long nose-like portion 1 and at the other end a tapered chamber 2, which lits over the coupling member of a lubricant-.expelling device,
as illustrated. The chamber is surrounded by a relatively thin'wall 3 which is provided with slots 4 ex- ,tending throughout the entire length of the chamber to permit slight expansion and con- .otraction of the wall.
The nose-like portion 1 is provided with a central passage 5 which communicates at its inner end with a lubricant-receiving nipple 6 threadedly secured /to the nozzle and surrounded by the wall 3.
coupling member of the device to which the nozzle is to be attached, I have preferred to illustrate a nipple substantially as shown and described in my copending. application,
Serial No. 616,302 now Patent No. 1,637 ,326..
The lubricating device, as illustrated, is also substantially as shown and described in the above-mentioned application, and the detachj While the nipple 6 may be of any suitable construction for proper engagement with the ablenozzle may be secured thereto by entering the discharge end of the device into the chamber 2 and rotating the ,barrel 7 of the device in a clockwise direction. Thus the lubricant-receiving nipple 6` is entered into the open end of the device and the male threads 8 located on the nipple engage the female threads 9 in the discharge end of the device, thereb gether until t e end of the nipple engages and opens the closure valve 10. At the same time the relatively thin wall 3 contacts with and is slightly expanded4 by the cone-shaped end 11 of the discharge end of the lubricantexpelling device, thus holding thel nozzle drawing' the two parts tov firmly connected to the lubricant-expelling device so that the substantially strong spring 12 behind the valve 10 cannot forcer the v alve 10 into closed position as it would, because of the pitch of the threads, if the wall-3 were not provided.
vWhen the nozzle is thus secured to the discharge end of the device, lubricant may be freely forced from the barrel 7 past the valve 10 through tlie'passage 'in the nipple 6 and through the passage 5 in the nose-like portion 1 into the part to be lubricated.
The seal betweenthe lubricant-expelling device and the nozzle is effected in. exactlyn the same manner as when theZdevice is connected with a lubricant-receiving.nipple/located upon some part of the car.l
The nozzle is also provided witha male thread 13, las illustrated, which may lbe l threaded into a supply tank or the like, so
that, when the lubricant-expelling gun is coupled with the nozzle, the gun lmay be filled from the front end thereof because the valve 10 in the gun is held open and lubricant may pass by it in any direction, as shown in Fig. 2. When the nozzle is used in the above mentioned manner, however, the ball check in the nipple 6 is substituted for a valve (not shown) which may be opened by involving omission, alterations, substitution and reversal of parts, and even changes 1n` the mode of operation, may be made Without departing from the vscope of Vmy invention, which is best defined in the following claims.
