OILING-TooL.

To all whom t may concern: i A

Be it known that I, BERTRAM C; CANDEE, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Oiling-Tools, of which the following is a specification. l

My invention relates to a hand-tool par-v ticularly adapted for quickly and conveniently oiling large installations of machinery for instance link belt conveyers. In conveying mechanisms of this and similar character it has heretofore been an inconvenient and laborious matter to effect the oiling for it was necessary to do this on holidays, or to shut off the power on other days, and even then the oilers were obliged to climb over the structure and to o il the bearings at most inconvenient points and positions, a slow and laborious matter. -In large' `structures or installations twol .men might easily spend a whole day doing this oiling, whereas with my tool, -particularly designed for. this work, the same may be clone in an hour or less often by a single operator; it is not necessary to shut off the power; one operator may stand at any convenient point and as the parts of the conveyer move past him shoot a uniform charge of oil into each-bearing.

For this purpose I have particularly designed my oiling tool, which consists'essentially of a pistol-like structure having a handle-portion made to lit the hand, and a barrel-like portion formed with a cylinder for receiving the measured supply of oil and with parallel, elongated channels through which the oil is delivered from the inlet in the butt, connected to a suitable sourceof supply, first to the cylinder and second from the cylinder to the nozzle. A four-way orA other suitable valve suitably arranged controls the direction of flow, and a piston in the cylinder is forced back and forth by the infiowing oil to force out one cylinder full at each reversal of the valve and consequent stroke of the cylinder, either forward or back. The operation is effected by a spring trigger in the handle.

My invention is shown in the drawings herewith in which the same reference numerals indicate the corresponding parts in all the figures.

In the figures 1 indicates the handle of the tool and 2 the barrel, the latter formed with the cylinder 3 extending from the rear wall 4 to the front end of the barrel where the cylinder is closed by screw-plug, or cylinder cap, 5, and with three longitudinal channels, the upper channel 7 the lower channel 8 and the deliverycoduit 9.' The channels '7 and 8 are respectively connected with the front and rear ends of the cylinder by front and rear ports 11 and 12. And through the valve ports 14 14 inthe rotating `valve 16 communication is alternately established between said channels and the inlet port 17 when one channel is connected through one valve port to the inlet port, for

admitting the supply of oil, the other channel is connected through the other valve port to theconduit for delivering one cylinder full of oil to the oil-cup, or bearing, in'question through'the nozzle 19 at the front end of the conduit. Theoil under suitable pressure is conducted to the inlet portfthrough the inlet pipe 21 from any suitable source of supply. The piston 22 is fitted to reciprocate within the cylinder and is provided with suitable packing 23 held secured thereto by the screws 24 which also act asstops. The

lrotation of said valve and the simultaneous filling and emptying of the cylinder, by lmeans of the piston moving alternately in opposite directions', is effected by the trigger 25 carried on the guide pins 26 provided with a suitable spring or springs 27 to return the trigger to initial position. Said pins are provided with heads 28 arranged in the head-holes 29 and acting as stops to limit the said outward movement of the trigger. U

The valve is journaled in its bearing in the valve core or butt 30 of the barrel and is secured on the valve-pin 31, which carries,

near its other end, the ratchet 32 fixed there on and the journaled arm 33. At the end of the arm is journaled on the ratchet-stud 35 the pawl 36, and said ratchet-stud is end gaged by the forked end of the trigger. The pawl-spring 40 holds the pawl against the ratchet. A dog 41 and dog-spring 42 may be provided to prevent'backward turn but probablyl will not generally be necessaryl for there would probably be enough friction in the parts to prevent any backward turn. 43 are washers and 44 are nuts for securing the valve-pin and parts thereon rotatablyin position. a

rllhe amount of oil received into the cylinder and the amount discharged therefrom at each stroke of the piston may be varied and regulated by removing the cylinder cap and inserting a piston of different length, but l, prefer to ei'ect such modification in stroke of the piston and capacity of the cylinder by means of stop-screw'45 inserted into said through pipe 21, inlet yport 17, one of the. valve-'ports 14, lower channel 8 'and vrear.

cap which mayl easily be adjusted as desired from the exterior by screw-driver or wrench.

The nozzle 19 may bemade longer or shorter or even extended into the form of a pipe if it is desired to deliver the little distance. y

As here shown the piston is in forward position and the cylinder is supposed to be filled with oil that is between the piston and thel rear wall, the -oil having beensupplied under pressure from the source` of supply port 12.v Now on pressure' 'of' thetrigger, the valve is given a quarter turn by means of the ratchet connection described, thus turning it into reverse position 4indicated in dotted lines in Fig. 1. Communication is.

' thereby established between the inlet-port vfront'- end and forcing out the charge of and the front end-of thecylinder through' upper channel 7 and front port 11, whereby the oil enters, filling the cylinderfrom the oil in the cylinder through the rear port 12, lower channel 8 and conduit 9, whence by nozzle- ,19, inserted into the `oil-hole, it is directed in the bearingor oil-cup in question. rlhus where kmovin-g parts are to be piled the oil may be supplied` easily and conveniently to each oil-'cup as it passes by the operatorv who takes his stand at the most convenient point, without the necessity of shutting downl the machinery. And a fixed and easily regulable quantity of oil may be delivered into each oil-cup or other recep-H tacle.

-On releasing the pressure of the hand, the trigger under. its spring pressure is forced-out to return the pawl to initial position ready to engage the next tooth and to f eiiect the nextI quarter turn of the valve.

While the form of tool here shown is d esirable yet the particular form and arrangement of parts may be varied without departing from my invention. While particu-p oil some merece larly designed for use with link-belt conveyers and other large installations, it is not limited to such purposes but may be used wherever desirable to deliver a xed charge of oil, or of any other liquid to any receptacle.
