UNITED STATES PATENT OFFIcE- ELIJAII MCCOY, OF DETROIT, MICHIGAN, ASSIGNOR TO HENRY C. I-IODGES AND CHARLES C. IIODGES, OF SAME PLACE.
D O P E C U P.
SPECIFICATION forming part of Letters Patent No. 460,215, dated September 29, 1891. Application filed November 6, 1890. Serial No. 370,525. (No model.)
.To aZZ whom, it may concern.-
Be it known that I, ELIJAI-I MCCOY, a citizen of the United States, residing at Detroit, county of IVayne, State of Michigan, have in- 5 vented a certain new and useful Improvement in Dope-Cups; and I declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it pertains to make I and use the same, reference being had to the accompanying drawings, which form a part of this specification.
It is the object of my invention to produce a dope-lubricator which will be simple in T construction and economical for use; and it consists of a combination of devices and appliances, hereinafter described and claimed.
In the drawings, Figure l is a vertical section of my cup. Fig. 2 is a side elevation of the same.
In carrying out in y invention, A represents the base of the cup adapted to be attached to the boxing or other part to be lubricated.
B is the body of the cup, screw-threaded at its lower end to fit onto the base. Extending above the body is the neck or tube 0.
D is a spindle, extending through this neck and down to the outlet-orifice a in the base. The end of the spindle is shaped to close this 0 orifice when the spindle is screwed down.
E is the piston working within the body and adapted to force the dope out through the outlet at, the piston being forced down by the spring E. This piston is guided and 5 steadied in its movement by the guide-rods F, which extend from the piston up through the top of the body and are engaged to the collar G, which embraces the neck or tube 0. Engaged to the upper end of the spindle is the thumb-piece D, which is screw-threaded to fit into the upper end of the tube. This thumb-pieceis provided with a projecting pin (Z. On the upper face of the collar G is a post or projection g. provided with the notch or 5 opening g to receive the pin cl. Now when the collar, and consequently the piston. is raised and the thumb-piece revolved the pin entering the notch holds the collar to its up permost position until disengaged by revolving the thumb'piece. So, also, by making the upper face of the notch g rounding, as shown,
the collar cannot be disengaged except by slightly raising the collar and compressing the spring and then revolving the thumbpiece. Then, again, thelength ot' the spindle is so proportioned that Where the thumbpiece and spindle are revolved to disengage the pin from the notch it forces the lower end of the spindle to its seat in the outlet-orifice and thus closes the outlet. cannot be raised and locked up Without first shutting off the outlet, and when it is desired to feed the dope .the size of the outlet or the feed cannot be regulated until after the piston is unlocked.
Another material advantage is that when the cup is empty the piston can be drawn up and locked and then the body unscrewed from the base, taken to the receptacle containing the supply of dope, filled, and returned to its base with the piston still locked up and out of the way.
What I claim is-- 1. In a dope-cup 1ubricator,the combination, with the body provided with a tubular 7 5 neck at its top and an outlet-orifice at its bottom, of a lengthwise-adjustable spindle moving in the tubular neck for opening and closing the outlet-orifice, an interior piston, and guide-rods extending from the piston through the top of the body and engaged to a collar, said collar sliding on the tubular neck extending from the top of the body, substantially as described.
2. In a dope-cup, the combination, with the body having a tubular neck at its top and an outlet-orifice at its bottom, of a spindle extending through the neck to open and close the outlet-orifice, and having an attached thumb-piece provided with a projecting pin 0 and in screw-threaded engagement with the neck, so that by turning the thumb-piece the spindle is raised or lowered, a piston in the body, and a guide for the piston having a collar provided with a notch for engaging the pin on the thumb-piece which raises and lowers the spindle, so that by turning the thumb-piece the pin is disengaged from the notch and at the same time the spindle is moved to close the outlet-orifice, substantially as described.
In a dope-cup, the combination, with the Thus the piston 60 body having a tubular neck at its top and an outlet-orifice at its bottom, and aspindle moving in the neck and having a thumb-piece in screw-threaded engagement with the neck, of a piston in the body having-a pair of guiderods provided with a connecting-collar, and a pin-and-notch connection between the collar and the thumb-piece, which raises and lowers the spindle, substantially as described.
4. In a dope-cup, the combination of the spring-actuated piston and its guide-rods engaged to the collar G, the thumb-piece D,
