The travel of said lever and 55 the connected rack 56 is varied by the provision of the stud 10 which is threadedly engaged in bore 1| of said bracket 60. It is apparent that said stud may be adjusted to vary the travel of the lever 62, and also the piston 51, and that said lever contacts the head 12 of said stud 10. In this way the amount of the lubricant to be expelled may be regulated in accordance with the needs of the service. In the present instance, the piston 51, borne by the rack stem 53, includes a follower plate 13, a washer 14 and an expansile ring 15 that holds the latter in position, said ring being engaged by a retainer 1, as shown in Fig. 6.
Upon inspection of Fig. 5 it will be noted that the cylinder 11 is closed at one end by a cap 10 having an opening 19 to receive the rack stem 30 carrying the piston III at one end and a knob 82 at its other end. The usual fitting 03 is arranged at the other end of the cylinder 111, said fitting including an internally threaded apertured boss 04 to receive the filler plug 85. The spout 86 leads from said fitting 03, its outer end being reduced in diameter, as shown at 81, to receive the oiler tip 88.
The form of check valve illustrated in Fig. 7 comprises the ball 89 which is pressed against its seat 90, of sleeve 9|, by means of spring 92 having its outer end abutting cross-pin 93.
It is obvious that as the piston is advanced in the cylinder, the latter having been previously filled with a lubricant, the latter is discharged through the passageway in the spout 86 where it proceeds through the oiler tip after moving said ball 89 from its seat 90. Normally the ball 89 is in the position indicated in Fig. 7 to prevent the leakage of the lubricant.
The cap 18 is provided with an extension 94 which serves as a bracket to support one end of the U-shaped handle or lever 95, the latter being made of springy strap material to permit the flexing of the leg portion 95a towards its companion. The upper end of said leg portion 950. is notched at 96 to partially embrace said rack stem and it also slidably supports a plate 91, notched at 99, (see Fig. 6), the bottom of the notch being shaped to engage in a selected tooth of the saw teeth arrangement 99 of said stem 80. The plate is held in the position shown in Figs. 5 and 6 by means of a spring I00 which rests in socket IIII carried by said leg portion a.
Upon inspection of Fig. 6 it will be noted that said plate 91 is slotted at I02 and I03, the headed stud I04 having one end in slot I02 whilst the stud bolt I05 passing through slot I03 maintains said plate 91 and said leg portion 95a in the positions indicated, the arrangement being such that said plate 91 may slide up and down the upper portion of said leg portion. Said stud I04 is passed through the handle 95 and bracket 34 where a nut I06 is applied which serves to bind the parts together; When the parts are in the positions shown in Fig. 5, the spring I00 urges the upper edge of said plate 91 into engagement with one of the teeth 99 and when the handle is grasped in the hand and pressure applied to the leg portion 95a, the latter is flexed inwardly thus advancing the rack stem and piston into the cylinder to expel the lubricant.
When the pressure is released on the leg portion 95a the plate 91 may be moved downwardly,
in view of slots I02 and I03, and when the leg' portion springs back to its normal position, said plate 91 is released, whereupon it moves upwardly to engage with one of the teeth 99. The movement of the piston 8| may be varied by manipumamas lating the adjusting nut I01 along the stud I03, thus limiting the inward movement of said leg portion 95a and the amount of lubricant to be expelled.
The piston arrangement, shown in Fig. 8, com prises a follower plate I38, a washer I09 held in position by means of ring IIQ and a retainer III.
From the foregoing it will be seen that the nut I01 may be positioned along the stud I06 and when. it is contacted by the leg portion 35a, the travel of the latter is restricted. As said stud may be quickly moved along said stud I36, the amount of lubricant to be expelled may be conveniently varied to meet difierent conditions.
In Fig. 9 the cylinder II 2 is provided with a fitting I I3 having an apertured threaded boss I III to receive the plug I I5, said plug being removable to permit the entrance of a lubricant into said cylinder. A spout H6 may be attached to said fitting II3, as indicated at III, whilst the outer end of said spout is reduced in diameter, as shown at H8, for the reception of the oiler tip M3, (see Fig. 12).
A check valve is mounted within the passageway of the spout IIG, said valve including a ball I20 normally pressed onto the seat I2I of sleeve I22 by spring I23 which abuts the cross-pin I24. The other end of said cylinder H2 is provided with a cap I25 having an opening I26 to receive the rack stem I21, the latter carrying the piston I28 at one end and a knob I29 at its other extremity. Said cap I25 is extended downwardly to present a bracket arrangement I30 that terminates with an apertured bearing I3I mounting a rod I32 aflixed to the lower end of lever I33, as indicated at I34, said lever I33 being provided with an offset I35 from which extends an upstanding portion I36, towhich is affixed one end of the threaded stud I31, as shown at I38. As shown in Fig. 9, the upper portion of said bracket I30 is cored out to present a cavity I39 having its end walls provided with openings I40 and HI, respectively, which serve as bearings for the slidable stud I31, and it will be noted that a spring I42 embraces that portion of the stud I 31 between the aforesaid bearings and also that a nut I43 is attached to the end portion of said stud. Said upstanding portion I36 is provided with a vertical bore I44 which houses a spring I45, which normally urges the ratchet I48 into engagement with a selected tooth of the saw-teeth I41 of said rack stern I21.
Upon inspection of Fig. 11, it will be observed that said ratchet I 46 has its shank portion I48 positioned within said bore I44 and that its upper end is bifurcated to embrace the sides of said rack stem I21 and to engage in a selected tooth. The parts being in the positions shown, the bracket I30 is grasped in the hand of the operator and the lever I33 is pressed inwardly and in view of the engagement of the ratchet I46 with one of the teeth of said rack stem I 21, the piston moves inwardly to expel a quantity of a lubricant. Obviously, the bearings provided by the openings I40 and MI, and the bearing I3I mounting the rod I 32, assures free and easy movement of the parts. During the aforesaid operation, the spring I42 is compressed and when the pressure applied to said lever I33 is released, the lever moves rearwardly and the ratchet I46 is depressed until it finally engages another selected tooth. In order to limit the travel of the lever I33 and piston I28, we provide a nut I49 that threadedly engages the stud I31 and which may be shifted to vary its distance from that point of the bracket I30 adjacent opening I40 thereby limiting the travel of the threaded stud I31. In view of this arrangement the distance of the nut I49 from that portion of the bracket contacted thereby regulates the travel of the piston and the amount of the lubricant to be expelled from the cylinder. Suitable portions of both the bracket I30 and lever I33 may be knurled, as indicated.
The preferred form of the piston assembly I28 is shown in Fig. 13, wherein it will be noted that we provide a follower plate I50 and a washer I5I; also an expansile ring I52 and a retainer I53.
We claim:
A lubricating device comprising a cylinder having a discharge opening, a cap carried by one end of said cylinder and having an opening, a rack slidably mounted in said opening, a piston carried by one end of said rack, a bracket integral with said cap having a cavity presenting apertured end walls, said bracket also having an aperture in its lower end, a rod slidably mountedin said aperture, a lever carrying said rod, said lever being provided with a bored upstanding portion, a spring-pressed pawl mounted in the bore of said upstanding portion and arranged to selectively engage teeth in said rack, a spring-pressed rod aflixed to said upstanding portion and being slidably mounted in the apertured end walls of said cavity, said lever being movable inwardly to carry said rack and piston in the same direction to expel a lubricant in said cylinder and adjustable means carried by said rod to vary the travel of said rack and piston.
