Beit known that I, FREDERICK G. TEEs, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Lubricators, of which the following is a specification.

My invention relates to a new and useful improvement in lubricators, and has for its object to provide an exceedingly simple and effective device by which either grease or oil may be fed to the bearings of machinery and so constructed that this feeding may be regulated and a further object of my invention is to provide for the operation of lubricators in multiple from one automatic actuating mechanism to put any or all of the lubricators in or out of action without arresting the operations of the automatic actuating mechanism and to provide for feeding any or all of the lubricators by hand.

Vith these ends in view thisinvention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order than those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure l is an elevation of a set of my improved lubricators, the base to which they are attached being in section; Fig. 2, a vertical section of one of the lubricators, Fig. 3, aplan view of one of the lubricators, the plunger-rod being sectioned; Fig. 4, a section at the line of Fig. 3 Fig. 5, a vertical section of the automatic actuating mechanism; Fig. 6, a plan view of the locking-ring by which the cover of the lubricator is secured in place; Fig. 7, a similar view of the cover.

Referring to the drawings, A represents the body of any one of the lubricators, which is preferably of cylindrical shape, and B is a plunger fitted to slide vertically therein. This plunger is rigidly secured to the lower end of the plunger-rod O and consists of two disks, between which is placed a compressible washer D, a nut E being run upon the reduced lower end of the plunger-rod, by means of which the washer may be compressed more or less, so as to increase its diameter,

thereby causing it to snugly fit the interior walls of the body A.

F represents the cover, which is provided with the plungers F, adapted to pass into the cut away portions G of the lockingring H, which latter is threaded upon the upper end of the body A, so that when the cover is in place the turning of the lockingring H will lock the cover in place, and as the locking-ring is threaded-upon the body the turning thereof will draw the cover tight upon its bearings.

I represents a nut fitted to revolve in the cover and held against displacement by the yoke J, secured to the cover by suitable screws, and this nut projects upward above the surface of the cover and has fitted upon its projecting end a worm-gear K in such manner that said gear when not otherwise locked to the nut may revolve freely around the hub thereof for the purpose set forth.

In order that the worm-gear may be locked to the nut so as to revolve therewith when occasion requires, a circular plug L is seated in a recess formed in the gear and the periphery of this plug extends intoa notch formed in the side of the projecting end of the nut, said notch being of the same curvature as the periphery of the plug. As will be seen, when this plug is turned tol the position shown in Fig. 3 it will lock the worin-gear to the nut, so that they will revolve together.

A notch L is formed in the plug of a curvature which corresponds to the periphery of the projecting end of the nut, so that when this plug is given a half-turn from the position shown in Fig. 3 the nut L therein will coincide with the periphery of the projecting end of the nut, thus unlocking the wormgear from the nut and permitting the former to revolve without revolving the latter, and to facilitate the locking and unlocking of the worm-gear and nut a key-shank L2 is formed with the plug upon which a key may be placed to turn the latter.

The plunger-rod O is threaded throughout' the greater portion of its length, so as to engage with the threads of the nut I, through which it passes, so that when this plungerrod is held against rotation and the nut revolved said rod will be forced downward, thus forcing the plunger downward and feeding the grease or oil from the lubricator.

In order that the plunger-rod may be held against rotation while the nut is revolving, a latch M is pivoted to the body A, its inner IOO IIO

end being forked, so as to embrace the flattened sides of the plunger-rod, as clearly shown in Fig. 3, and on account of this latch being pivoted it may be swung backward out of engagement with the plunger-rod, thus leaving the latter free to revolve when occasion requires.

N is a bracket secured to the body of the lubricator and having secured therein the sleeve O, which latter has formed thereon the disk Q, and this sleeve serves as a bearing for the spindle P, which has secured upon its outer end the worm-wheel P", which meshes with the worm-gear K, so as to revolve the latter, and to the opposite end of the spindle P is secured the ratchet-wheel Q. Around this ratchet-wheel is a circular housing R, formed with the disk Q, and a portion of the circumference of said housing is cut away so as to expose a certain number of the teeth of the ratchet-wheel Q, for the purpose hereinafter set forth.

A cam S is pivoted upon the spindle P and lies against the disk Q within the housing R, a portion of the circumference of saidcam coinciding with the outer periphery of the housing while the remaining portion of the circumference of said cam drops away toa point below the base of the teeth of the ratchet-wheel Q. This cam has a screw S threaded therein, which projects through a slot in the disk Q in order that the cam may be adjusted and when adjusted held in place by tightening up upon the screw.

T represents the actuating ratchet-wheel, which is fitted to revolve upon the housing R, and onthe inside of the ratchet-wheel is pivoted a pawl T, forced inward by the spring T2, as will be clearly seen by reference to Fig. 4. This pawl rides upon the outer periphery of the housing R until reaching the cut-away portion thereof, when it will be swung inward and come into engagement with the teeth of the ratchet Q as the ratchet T is revolved. Now as a portion of the periphery of the cam S coincides with the periphery of the housing this pawl in its travel with the ratchet-wheel T will also ride upon the periphery of said cam, and as said cam is adjustable relative to the cut-away portion of the housing its adjustment will determine the number of teeth of the ratchet-wheel Q which will be eXposed to the pawl T during each revolution of the latter, for as long as the pawl is riding upon either the housing or its cam it cannot engage with the teeth of the ratchet-wheel Q, and therefore cannot actuate the same.

In order that the actuating ratchet-wheel T may be revolved step by step, a lever U is pivoted upon the housing R, so as to swing concentric therewith, and this lever carries a spring-actuated pawl V, set therein, said pawl engaging with the teeth of the actuating-ratchet, so that at every to-and-fro movement of the lever this ratchet will be moved step by step, and the lever may be connected with any suitable mechanism for giving it this to-and-fro movement,or it may be weighted and utilized as a pendulum in order that itv may swing to and fro when the lubricator is attached to a reciprocating part of a machine, such as a cross-head of an engine. i I.

A cap U, having the body thereof threaded when in engagement with interior threads formed in the housing, holds the lever U in place.

From the foregoing description the operation of my improvement will be obviously as follows: The lever U being moved to and fro will, through the pawl V, revolve the ratchet T step by step, and in so doing carry the pawl T around upon the housing and the cam S until it comes in engagement with the teeth of the ratchet-wheel Q, when it will move said ratchet-wheel in unison with the ratchet-wheel T until again riding out of engagement with the teeth of the ratchet- Awheel Q, leaving the latter stationary, while the ratchet-wheel T continues to revolve. l/Vhile the pawl T is in engagement with the ratchet-wheel Q and the latter revolved thereby the worm-wheel P upon the same shaft with the ratchet-wheel Q will also be revolved and in turn revolve the worm-gear K. The revolving of this worm-gear will revolve the nut T when locked in engagement with the latter, and thereby feed the plunger-rod C and plunger-rod B downward, so as to effect the feeding of the lubricant to the bearings, and should it be desired to increase or de-v crease the amount of this feeding it may be readily accomplished by adjusting the cam S through the medium of the screw S, by which a greater or less number of teeth of the ratchet-wheel Q will be exposed to the action of the pawl T during each revolution of the latter.

Should it become desirable to feed the lubricant by hand, it is only necessary to swing the latch M backward out of engagement with the plunger-rod, after which said rod may be turned by grasping the knob W and revolving the plunger-rod in the proper direction, when the plunger will be fed downward to any suitable extent.

For convenience in manipulating the locking-ring H a knob H projects therefrom, so that the operator by grasping this knob may readily manipulate the locking-ring for removing the cover or locking the same in place.

Tnutilizing a multiple set of lubricators I arrange the caps or bodies A in series, as shown in Fig. 1, bolting them upon the base a by means of the nuts b run upon the nipples c, and each of these lubricators is 'so set relative to the one containing the actuating mechanism that the gear-wheels K mesh IOO IOS

IIO

ISO

. worm-gear fitted to revolve around the nut,

with each other in order that when the first gear-wheel is operated by the actuating mechanism, as before described, its rotation will likewise rotate the gear-wheels of the remaining lubricators of the series, thus feeding the lubricant from each of these lubricaters.

When it is desirable to throw out of action one or more of the lubricators, this is readily accomplished by turning the plug L so that the notch L thereof registers with the periphery of the nut I, thereby unlocking the gear-wheel K from the nut, as before del scribed, thus permitting the gear-wheel to l revolve idly without effecting the feeding of the plunger-rod.

I/Vhere grease is to be used in the lubricator, the nipples c are connected with the bearing to be lubricated; but in ease oil is used then a gooseneck d leads from the bottom of the lubricator, its upper end being connected with a glass tube e, so as to form a sight-feed or, if desired, the lower end of this gooseneck. may be attached directly to the nipple c.

For certain purposes, such as automobiles, a series of feed-pipes f may lead from the bottom of the lubricator, so as to convey the lubricant to different bearings.

In order that the gear K may be revolved independent of the actuating mechanism, a key-hold g projects from the worin-wheel I, so that by the application of a key to this key-hold the worm-wheel may be revolved independent .of the actuating mechanism, which in turn will revolve the gear K.

The body of the lubricator may be square or other angular shape which will hold the l plunger against rotation, thereby doing away l, with the latch M. l

I-Iaving thus fully described my invention, l 'what I claim as new and useful is# l. A lubricator consisting of a body forming a container for the lubricant, a plunger i adapted to slide vertically within said body, l

a plunger-rod rigidly secured to the plunger, y. means for holding rod against rotation, a nut through which said rod is threaded, a
