LUIBRICATOR.

SPECIFICATION forming part of Letters Patent No. 590,297, dated'september 21, 1 89'7. Application and January 2, 1897. Serial No. 617,819. {No model.)

particularly of the kind known as forcefeed, and it has for its object to provide means whereby several engines or machines may be supplied with lubricant from a singlelubrieator and the quantity of oil fed to each regulated to a nicety. IIeretofore it has been customary to provide a separate lubricatingdevice for each engine or portion of a machine to be lubricated or else a single lubricator, usually one operatedby the condensatien of steam, supplying several machines or parts, but in the latter not only .is difliculty encountered in subdividing the lubricant and particularly proportionin g it for the variousdevices, but the supply is not dependent upon the actual running of the part itself or that to which it is connected, and, on the other hand, it is not always convenient to apply a lubricator and to operate it from the machine to which it- 'is connected.

In. my device I provide a'single construction embodying one movable part operated from any convenient prime mover, as the engine itself, and connected with this part are independently-adjustable feeding devices, as pumps, so that by means of the adjustments the operator can regulate not only the exact quantity that is required for any "moving parts without stopping the operationof the movable part or device, but the frequency with which this quantity is supplied. I

The invention consists in certain improvements whereby the above ohjectsare carried out, and also in certain details of construction, all of which will be more fully stated in the claims at the end of this specification.

In the drawings, Figure 1 is a'front elevation of a lubricatorcontaining my improvements, a portion of the actuating-wheel beiug broken away; Fig. 2, a vertical sectional view through the pistons of the pumps, showing theactuating-cam; Fig. 3, a horizontal sectional view; taken just above the pumpcylinders; Fig. 4, a vertical sectional view on the line a: a: of Fig. 1-; Fig. 5, a similar view on the line 'y y of Fig. 3; Figs. (5 and 7, detail views of the clutch device for actuating the pump, and Figs. Sand 9 similarviews of a modification.

Similar reference-numerals in the several figures indicate similar parts.

The main frame of the lubricator embodies a cup or reservoir 1 for the lubricant, having a suitable cover 2, and formed upon one side of the base thereof is an enlargement in which are formed (preferably by boring vertically into the enlargement) two or more cylinders 3, in which operate pistons 4, passing through suitable stuffing-boxes formed in mmovabie In tbe'prescaps 5, screwing into said base; ent instance I have shown two pistons 4, each provided with aring or stop 6, and their upper ends pass through apertures formed in a movable member, as "a cross-head 7, pivotally connected to the lower end of a pitman 8, the upper end of the latter being strapped to a cam 9, formed upon or secured to the inner side of a driving-wheel 10, pivot-ed upon a belt or pin 11, secured to the side of the cup or reservoir, so that as the wheel is rotated in the direction indicated by the arrow in Fig. 1. the cross-head 7 will be moved vertically. The connection between the cross-head 7 and the pistons is formed by lock-nuts 12, screwing on the upper ends of the pistons above some distance from the collar 6, allowing the cross-head'to play on the rod and only engage it at its extreme upward and downward movements, thereby making a very short stroke of the piston and, as will be seen, forcin but very little oil. The pistons are of such nature end of the drill forming the seat;

sition until operated positively by the cross head engaging the nuts or the collars 6. Each of the cylinders basin its lower end a valveseat 13-, upon which rests a ball 14, and beneath this is a smaller valve-seat.15, upon which -rests a ball-vave 16, said seats being formed by boring in from the top with drills of diiferent diameters, the countersink at the- 17 17 indicate inlet-passages from the interior of the reservoir -to the bottom ofthe cylinder'beneath the valve 16, and whichare bored from the outside, the outer ends of said passages being closed by screw-plugs 18.

19 indicates discharge-passages from the pum-pscylinders above the valves 14, the vertical portions of said passages being provided with valve-seats of different diameters formed by boring, as described, with which codperate ball- valves 20 and 21 ,and above said ralves the passages are continued in the form of pipes or conduits 22,1eadihg to the machines or surfaces to which it is desired to supply the lubricant. Byforming the valveseats of different diameters I am not only enabled. to 'cheapen the construction of the apparatus materially, but also to employ double check-valves which I find are particularly advantageous, in thatbothvalves of the pair are not liable to become clo'gged at the same time by dirt or sediment, so-th-at the proper feed of the-lubricant is assured.

- The means employed for rotatingthe cam 9 may be of any suitable construction, but I prefer to actuate the wheel 10, to which the cam is connected, by means of a clutch on the end of a lever 25, pivoted on the bolt or pin 11 and having the slotted lower end connected by adjustable links 26 27 with a slotted lever or rock-arm 28, actuated by a. reciprocating connecting-bar 29', secured to the block 30,- adjustable in the slot of the'arm 28, this. adjustable connection being substantially the same as that contained in Letters Patent No.

ating device could be employed. The adj netment between the reciprocating rod 29 and the lever enables me-to regulate the speed of the wheel 10-, and the adjustment between the cross-head 7 and pistons to regulate the length ef stroke of the latter, and thereby the quantity of oil fed at each reciprocation.

The particular construction of clutch de-,

vice I prefer is shown in Figs. 6 and 7, the periphery of the wheel 10 being formed'with I a groove 10 and the end of the arm 25 with clamp-the ball between the recess in the arm and the groove in' the wheel and turn the latfer, the ball loosening itself as the lever is,

moved in the opposite direction. p

In Figs. 8 and 9h lieu of the ball a roller 25 is shown held in place by a plate 25 and adapted to grip the face of the wheel 10, which may be plaiii, or ratchet devices, such as shown in the Butler patent above referred to, could be employed for the same purpose. 35 indicates a gage for indicating the quantity of oil remaining in the receptacle'orresrvoir. 3 The operation of thedevice will now be understood. The pipes 22 being connected to the journals or other parts to be lubricated and'the rod'29 being connected to and 're'cip-- rocated by-the engine or other prime mover the wheel 10 will be actuated in the direction indicated' and at the speed desired,-causing the pistons'to be re-ciprocated, drawing oil from the reservoir through the conduits 17 and valves 14 andlG to the cylinders during the upward movement of the pistons, and as the .latter move down the oil in the cylinders vwill be discharged into the passages 19 and pipes If only a small quantity of oil is to be forced to one of the i es, the connection between the piston controlling it and the cross-head is loosened by moving up the nuts 12, as-shown at the right 'in'Fig. 2, so that the cross-head will only actuate the piston at the extremes of its movement and the stroke will be very short.

If desired, a greaternumber of pistons can I be actuated from a si'ngle'cross-head, and the adjustmentsdescribed beingemployed one" idly secured-sets, for instance, by tightening. the'packing by screwing down the glandandin the construction shown it would thenserve as a guide for the cross-head 7, while the connection between said cross-head and the piston that is actuated maybe regulated to feed. the desired quantity of lubricant.

- This apparatus ism sch more accurate than a. condensing sight-feed lubricator and, as

will be understood, can be employed for feeding oil to pipes containing steam under pres sure. v
