Appumion mea March 12, 1900. sain no. 8.294. (No man.)

' particular subject-matter which we consider novel, may be best explained in the subjoined description of an apparatus which embodies it in what we consider its best form and which we have illustrated in the accompanying drawings.

In the drawings, Figure 1 is a front elevation of a lubricator with six pumps. Fig. 2

is a rear elevation of the same. side elevation of the same. Fig. 4 is a plan view of the same. Fig. is a sectional elevation of one of the pumps, taken longitudinally through .the body of the pump and through the discharge. Fig. 6 shows the ratchet and pawl for driving the pumps. Fig. 7 shows the means for operating the pawl from an irregularly-moving part of an engine, such as the valve-rod of a locomotive,` Fig. 8 is a longitudinal sectionof anindicator for showing whether the lubricator is feeding.

In the several figures, 1 represents 'a reservoir `for .containing a lubricant. This reser- Fig. 3 is a voir is provided with a filling-hole'ata suittogether in a series, so' that they may all be able point and with a screen 2 therein.

1 -3 are pumps mounted on thereservoir and*l corresponding in number with the number of points to which the lubricant is to .be forced.' The construction ofithese pumps is more particularly shown in Fig. 5 and will be described farther on. They are arranged. near operated by a single cross-head.

4 is the cross-head by which the pumps are operated. The cross-head is guided in its movement by the guide-studs 5 and is provided with-ears 6 to engage the pump-plungers and is operated by the part to be next described.

7 is a shaft journaled in a standard 8,which is mounted on a reservoir 1. This shaft 7 is provided at .,oneend with a crank, whose pin 8 plays in a slot 9 inthe cross-head 4, thereby reciprocating the cross-head when Vthe'shatt is rotated. At'its'otherend'the shafges p1 0 55 vided with a ratchetwhQQI-loby .Whh it rotated. ,v 1 i 11 is a gravity-dog for preventing-aretr grade rotation of wheel 10.r

12 is a sleeve loosely inga pawl'l. Y

17 is an arm on the sleeve, which is oscillated by a rod 18 or otherwise, thereby oscil-l 65 lating the sleeve,.the disk, and the pawl, and so rotating the shaft 7 with a step-by-step motion, and thus reciprocating the cross-head Ltand operating the pumps. By means o f the screws 13 the pawl-carrying arm 15 may be 7o brought into any desired relation to the operating-arm 17, thus making it possible to have the pawl on the upper part of the wheel 10 whatever may be the position of the driving-arm. This enables us' to use a, gravity-y 75 pawl and dispense with a'sprin'g for keeping the pawl in engagement. The arm 17 is oscillated through the rod 18 or some equivalent mechanism from any convenient moving part of the engine to be lubricated. In some cases 8o this moving part has a motion which is irregular-as, for example, the valvefrod ofta locomotive, whose motion varies with the point of cut-off to whichthe valve is set at the moment. rod or other moving part to which we wish to connect a cam-piece 19, (shown in Fig. 7,) in which 20 is the valve-rod to which the campiece 19 is attached, and 21 is a bell crank lever pivoted at 2 2 to some convenient fxedpoint 9o and provided with a friction-roller 24 on its arm 23. The end of the upright arm is counected to the rod 18. the cam-slot 25 in the piece 19 has an oblique section near its middle and that the two end 95 sections are parallel with the travel of the des, vice. The oblique section corresponds in length with the shortest travel of the rod 20,' so that whatever the travel of the rod may be between that and full stroke the oscillation Ioo of the lever 21 is the same, and consequentlyr the amount of lubricant pumped is the same.

mounted on theshaft 6ov 7 and connected by screws 13.150 a loose disk 14, which is provided withan a'rml,carry--v In such cases we attach to the valve- It will be observed that In Fig. 5 we have shown vthe construction of our pumps.- 26 is the bodyof the pump,

Y which is provided with an ear 27, by which it is 4screwed to the top of the reservoir. 28 is theysuction-valve, of spherical form, held in place by the pump-barrel 30, which screws into the body. is the plunger moving in '.tbe barrel 30 and packed by some packing 31 fbetween the barrel and the cap 32, screwed thereon. The upper ends of the pump-plungers are threaded and extend through the ears G of thecross-head 4. One or more nuts 33 and 34 on each side of the ears cause the cross-head t-o move the plungers as it travels up and down. The stroke of the plungers is thus regulated by setting the nuts 33 and 34 at a greater or less distance apart, thus allowing more or less lost motion to the cross-head.

' 35 is the discharge-valve of the pump, also of spherical form, pressed to its seat by a spring 36, whose tension is adjusted by a plug 37. This spring also serves where the apparatus Y islubricating a steam-cylinder to close the lnected, and the valve and prevent the lubricant being sucked through by the vacuum resulting from shutting oli:` steam from the cylinder. 38 is a union to connect the pipe 39, preferably of small diameter, which conducts the lubricant to the point of use. A similar small pipe 40 is screwed into the suction-orifice of the puln p. If it be desired at any time t0 remove one of t'ne pumps for any purpose, the screw 2'7 is taken out, thus disconnecting the pump from the reservoir. The plunger is ,then freed from thiA cross-head 4, the union 38 is disconpum p lifted right out of place. It is put back again by reverse operations.

To show whether the apparatus is actually feeding lubricant to the point of u seyor not, we provide an indicator'. (Shown ymore particularly in Figs. 4 and 8.) '4l is a"`c'ylinder interpolated in the feed-pipe at any convenient poin t,so that the lubricant passes through it, as indicated by the arrows-that is, from 42 to 43. 44 is a piston' moving freely in the cylinder 41. The stem 47 of this piston extends through the cylinder and through a stuffing-box 45 and terminates in a button46. When the apparatus is in operation, the piston 44, with the stem and button, will be pushed out by the lubricant till the piston is past the opening 43.* If now it be desired to know whether the apparatus is feeding, the 'operator pushes the button in with his hand and the stem and piston with it to the position shown. Then when he removes his hand the parts will be pushed out again by the lubricant moving through the device, thus giving an ocular-demonstration that the apparatusis operating. When the piston is pushed clear out, it seats against the end of the cylinder, thus relieving the stuflinglrbox and shutting oft' the lubricant from it.

In some cases instead of the indicator of Fig. 8 we use a pressuregage 43,-Y Fig. 3, on the discharge or feed pipe. This shows the pressure on the lubricant, and also by the vibration of the needle shows that itis feeding. If the needle does notJ vibrate,'the operator knows at once that the feed has stopped, for We have discovered that when the lubricant is moving through the pipes the needle of the gage is in constant vibration. 49 is an ordinary glass gage to show the level of the liquid in the reservoir.

Itis of course to be understood that the foregoing apparatus may be varied structurally in many respects Without departing from our invention.

We claim- .1. In a lubricating apparatus, the combination of a reservoir, a pump for forcing the lubricant from the reservoir to the point of use, a cam-piece attached t-o a moving part of the engine lubricated, and provided with au oblique section and parallel sections and connections between said cam piece and pump, whereby the pump receives a uniform stroke, independent of the variations in the stroke ot' the cam-piece, substantially as set forth.

2. In a lubricating apparatus, the combination of a reservoir 1,a shaft 7 rotatably mounted on the reservoir, one or more pumps 3 mounted o n the reservoir, studs 5 on the reservoir, a crosshead 4 reciprocated on and guided by said studs and provided with one or more ears 6 to engage the pump-plungers, a connection between the cross-head and the shaft whereby the rotation of the former'reciprocates the latter, and means for rotating the shaft, substantially as set forth.

3. 'ln a lubricating apparatus,'the combination of a pump, a discharge-pipe for the.,

pump, a 4cylinder connected to said pipe, formed with an inlet and a lateral outlet for the lubricant, a plunger in said cylinder actuated by the lubricant passing through the pump discharge-pipe, and an external indicator connected to said plunger and adapted byits movementto show the motion of the lubricant in the pipe, substantially as set forth.

4. In a lubricating apparatus, a pump for Vforcing the llubricant comprising'in combination a body containing the two valve-chainbers, a pump-barrel adapted to be inserted in the body 'and limit the opening of the suction-valve, two valves of spherical form, a plunger adapted to the barrel, a spi ral spring to close the discharge-valve, anda plug adapted to be screwed into the discharge-orifice against said sprin g, substantially as set forth.-
