LUBRICATOR.
SPECIFICATION forming part of Letters Patent No. 731,731, dated June 23, 1903.
Serial No. 108,856. (No model.)
To all whom it may concern:
Be it known that we, EDWIN ALLEN, residing at Mount Vernon, Westchester county, New York, and GEORGE WALLACE CARVER,
residing at Brookline, Norfolk county, Massachusetts, citizens of the United States, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.
Our invention relates to improvements in force-feed lubricators, and we have aimed to avoid a number of objections incident to lubricators generally used and to simplify the construction thereof and materially rei5 duce the cost.
Among the advantages We have aimed to secure are, first, to provide a construction wherein the working parts may be readily detached and removed for cleaning or repair without disconnecting the reservoir from the engine; second, tolenable the fiow of oil to be more easily regulated, and, thirdly, to simplifythe operatingconnections, while permitting any degree of adjustment.
We have illustrated the invention in the accompanying drawings, in which Figure 1 is a front elevation. Fig. 2 is a side elevation, partly in section. Fig. 3 is a horizontal section taken on the line of the opcrating-shaft. Fig. 4 is a central vertical section also taken on the line of the operatingshaft. Fig. 5 is a sectional elevation of a modification having only a single feed; and
Figs. 6 and 7 are respectively a sectional plan and an elevation of a modification having four feeds, certain parts being omitted for, clearness of illustration.
Similar reference letters denote corresponding parts throughout the several views.
Referring first to Figs. 1 to 4, inclusive, the body or reservoir for containing the oil is indicated at A, which is provided withv an enlarged or flanged base A, by which it may be bolted securely to the engine-frame or other desired part. A suitable strainer B is provided near the upper end, above which is a suitable cover 1 to provide for the entrance of oil.
At the front of the reservoir and spaced therefrom for a suitable portion of its length is a suitable member or casting 0, containing the piston and valve chambers, as hereinafter-described. This memberO is preferablya Substantially rectangular block and is secured to the reservoir near its lower end by suitable means, such as screws 0 c, the res ervoir having asuitably ground or planed face 0 to provide a bearing and secure an accurate fit.
Vertical piston chambers or cylinders D are formed in the member O in any suitable manner, as by boring, and in these cylinders or chambers are .located the pistons E for f0rcing the oil. The upper portions of the cylinders or piston -chambers' are preferably bored out to a larger size to form an annular space for the reception of packing material e, which may be compressed by suitable glands e, threaded into the upper ends of the chambers and encircling the pistons. Valve-seats D and D of successively-decreasing size are formed at the lower ends of the piston-chambers, upon which are seated valves (preferably ball) (1 and d and passages a and a. in the member or block 0 and the adjoining part of the reservoir permit the passage of they oil from the reservoir to the spaces beneath the lower valves. Valvevchambers Q are also provided in the member or block C, preferably parallel with the piston-chambers, in which are placed successively-acting ball-valves q and q of difierent size, cooperating with the valve-seats Q and Q formed by reducing the boring of the chambers similar to the valve-seats D and D The oil-feed pipes L leading to the parts to belubricated are tapped into the upper parts or ends of these chambers Q.
Horizontal passages (1 lead backward from the spaces beneath the valves (1 to the piston-chambers above the valves D, as clearly shown in Fig. 2.
In order to reciprocate the piston E, we provide a slide G, suitably guided in the space between the block or member 0 and the reservoir, preferably in a vertical groove formed in the block 0. This slide is provided with upper and lower projections or ribs 9 and g.
between which is located a earn 0, mounted upon a shaft 2', journaled in the block or member (3 and operated from a moving part of the engine or prime mover, as hereinafter described.
' At its upper end the slide G carries a crosshead 1 which extends at either side into elongated vertical slots e in the upper end of the pistons E. These slots are of such length that if no other means of connection were provided the reciprocation of the slide would impart little or no movement to the pistons. To secure the requisite amount of movement of the pistons, each is provided with a set-screw c tapped into its upper end, and it will be seen that by adjusting these screws the amount of free movement of each piston may be independently varied at will, or, if'desired,-one or both pistons maybe rigidly connected to the cross-head whereby the movements of the slide and piston are made coextensive. This causes the pistons to deliver the maximum amount of oil.
In order to rotate the shafts, and thus impart movement to the slide, we secure upon the shaft in front of the member (1 a ratchetwheel I. Upon the shaft in front of this wheel is jonrnaled a hub K, carrying an arm 70. This arm 7; is provided at its outer end with a suitable spring-pawl 75, designed to engage the teeth of the ratchet-Wheel and impart movement thereto when the arm is swung in one direction, but to ride freely over said teeth when moved in the opposite direction.
Au arm K has one end pivotally mounted on the hub K, to which it is adjustably secured by a set-screw P, while its other end is adapted to be operated by a prime mover in a manner well understood by those skilled in the art. It will thus be seen that the arm K may be adjusted into either a horizontal position, as indicated in Fig. 1, or into a vertical position, or, in fact, into any desired position throughout a complete circle, thus adapting the lubricator to any form of engine, either horizontal or vertical, and to any position and dispensing with a multiplicity of levers and connections. By this construction it will be seen that we avoid any parts lying in the path of the arm, which, as just stated, is free to be adjusted to any desired position.
if desired, a crank t" maybe secured to the end of the shaft, by which it may be rotated by hand independently of the connections to the prime mover.
ilnorder to regulate the speed of rotation of the wheel I, we provide a shield J, which is supported by a suitable bracket from the member C and extends over or above the teeth of the wheel for approximately one-quarter of the circumference thereof. With the parts in the position shown in Fig. 1 the motion of the arm 7,: will impart a maximum amount of movement to the ratchet-wheel, supposing the arm K to be at the backward limit of its movement. When, however, it is desired to reduce this amount of movement, the arms K and 7c are adjusted with relation to each other, so that the pawl during a portion of its movement rides idly over the face of the shield. The portion of the stroke of the pawl thus rendered ineffective depends solely upon the relative adjustment of the arms.
It will be readily understood that the lubricator may be made with any desired number of feeds, and in Fig. 5 we have shown how the parts would be modified for a single feed. In this form the piston-chamber D would be located upon one side of the shaft 5 and the valve-chamber Q upon the opposite side. The port (1 would extend laterally across the block and be closed at its outer end by a screw (2". The slide would of course have but a single arm g engaging the slot in the piston E.
In Fig. 6 and 7 we have shown how the parts would be modified to provide a four-feed lubricator. In this case the block would be bored for four cylinders D and four valve-chambers Q, as shown in Fig. 0. Two slides G and G5 are provided, one upon the front face of the member or block 0 and one upon the rear, each being operated by an independent cam C, mounted upon the shaft 1' rangement permits the cams to be located in opposite relation, so that the slides are worked alternately, so that when one set of pistons is on the forcing stroke the other set is on the suction-stroke. The advantage of this will be readily apparent when it is noted that the pumps work against high steanrpressure.
lly placing all the working parts on or in the member C we provide an extremely simple, compact, and eiiicient construction and secure an important technical effect in being able to readily remove all of the parts for re pair or cleaning without removing the oilreservoir from the engine-frame.
The passages from the oil-reservoir are so small and the oil used in these devices so thick that the member 0 may be removed and the holes plugged up with temporary wooden plugs without the loss of an appreciable amount of oil.
A further important advantage of our construction is that owing to the size and shape of the member 0 it may be very easily handled in planing and drilling to get it in proper condition.

In combination an oil-reservoir, a member having a piston chamber or cylinder with a piston working therein, said member being detachably connected with the face of the reservoir and having a vertical guideway in its face, a slide moving in said guideway, a shaft jourualed in said member, means carried by the shaft for operating the slide,means connected with the shaft for operating the same, and a connection between the slide and piston, substantially as described.
