Towll whom it may concern:

e Be it known thatI, MINOR W; TAYLOR, of Waterloo, in the county of Blackhawk and State of Iowa, have invented certain new and useful Improvements in Lubricating Devices;

and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.

This invention relates to improvements in` devices for applying lubricating-oil to the bearings of machinery, said device beingot' that general class comprising a font orv recept-acle located' above the bearings to be lubricated, a plurality of'discharge'ducts or4 tubes leading from said receptacle to the several bearings, and a valve mechanism constructed to allow oil to ilow from the receptacle to the said ducts or tubes, whereby determinate charges of oil may be passed from the receptacle to the bearings.

4My invention is herein shown as applied` to oil the bearings of a windmill; but thedevice may be employed equally well for applying oil to the bearings of machinery of other p classes.

manner of attaching the lubricating device to a windmill and connecting the same with the several bearings thereof, only such parts of the windmill structure being shown as are lnecessary to illustrate the application of my improvements thereto. Fig. 2 isy a rear .elevation of the device removed from thewindmill. Fig. 3 is a top plan view thereof with the cover of the receptacle removed. Fig. 4 is atop plan view of the tube-supporting plate. Fig. 5 is a front elevation of the device. Fig. 6 is a top plan view of the rotary valve-plate of the valve mechanism. Fig. 7 is a central vertical section of the lower lend of the oil font Or receptacle, illustrating the valve and oil-distributing mechapism.

As shown in the drawings, A designates the font or receptacle for containing the oil.

Said receptacle is supported on a base-plate B, which is attached in any suitable manner to the machinery to Whose bearings oil is adapted to be applied by the device, the receptacle being herein shown as attached to the base-plate by means of bolts b.

Only such parts of the windmill are shown asare necessary to illustrate the application of the device embodying my improvements thereto.

C designates the usual tower-cap, on which is revolubly mounted the rotative head D, which carries the operative mechanism of the mill.

E designates a horizontal bearing-sleeve supported on the upper end of a bracket D', extending upwardly from the head and in which theshaft E' for the motor-Wheel is rotatively mounted. E2 designates a second horizontal sleeve supported on the `bracket D', in which a counter-shaft E3 is mounted. The wheel-shaft is provided with a gear-pinion e, which intermeshes with a gear-wheel e on the counter-shaft E3.' Said gear-wheel e is provided on one face thereof with a wristpin e2, which has bearing in an aperture in the upper end of a vertically-re'ciprocating pitman F, they other` end of saidpitman being adapted `for connection with the upper endof the pump rod or bar. The lbase-plate B is attached by bolts or the like to a bracket D2, projecting upwardly from the bracket D', thereby elevating the font or receptacle above the Various bearings, the oil flowing by gravity to the bearings.

The bearings to be oiled herein shown are those for the shaft E', the counter-shaft E3, and the wrist-pin e2. For this purpose two oil-cups e3 e3 are provided on the sleeve E,

'two oil-cu s e4 e4 on the sleeve E2, and an oilcup e5 at the upper end of the pitman for the wrist-pin e2. Oil tubes or ducts A4 A5 A6 A7 A8 lead from the receptacle to the various oilcups, the rst two to the cups es, the second two to the cups e4, and the last to the cup e5.

vSaid bearings require varying quantities of oil to properly lubricate the same, it being obvious that the bearing for the shaft E requires more oil to lubricate the same than the bearing for the shaft E3 and that the IOC wrist-pin requires less oil than the shaft. The valve mechanism by which the supply of oil to the several bearings is controlled is so constructed as to supply varying quantities of oil to the different bearings, as stated. Said valve mechanism is also arranged to supply a uniform amount of oil to each bearing at each usual operation of the valve mechanism, whereby a determinate quantity of oil is assured to each bearing for each operation of the device.

Referring now to the details of the mechanism by which the operations above set forth are performed, said parts are made as follows:

The bottom A of the receptacle A is made fiat and is provided with a plurality of annularly-arranged discharge-openings' ct equal in lnumber to the bearings to be oiled.

I designates a rotative valve-plate, which is located below the bottom of the receptacle A and is rotatively mounted on a short shaft or stud A2, depending from said bottom. Said valve-plate is provided with a plurality of annularly-arranged openings t', Figs. 3 and 7, which are normally out of line with the openings a in the bottom of the receptacle, as indicated in dotted and full lines in Fig. 3, and areadapted to be brought to register with said discharge-openings when the valveplate is turned in the proper direction, as shown in Fig. 7. Said valve-plate is provided on its margin with an upwardly-daring flange l', which lits outside of and overlaps a conical annular part at thevbottom of the receptacle, as shown in Fig. 7.

J designates atube-supporting plate, which is non-rotatively mounted on the stud A2 below the valve-plate I and is provided with a vertical annular iiange, which [its outside of and overlaps a depending annular ange t' on the valve-plate I. Said valve-plate is provided centrally thereof with upwardly and downwardly projecting annular flanges i2 t3, the upper one, ft2, of which is located in line with the annular recess shown in the bottom A of the receptacle and the lower one, fis, of which has con tact with the inner surface of the tube-supporting plate J and fits within an upwardly-projecting annular angej on said plate. The valve-plate and tube-supporting plate are held in position by means of a spiral spring K, surrounding the stud A2 and interposed between a boss on the lower side of said plate and a nut A3, which has screwthreaded engagement with the lower end of the stud A2. The said tube-supporting plate J is provided with a plurality of openingsjz, equal in number to and located below the discharge-apertures a of the receptacle A. Said openings j2 are surrounded by depending screw-threaded bosses, and the upper ends of the oil tubes or ducts A4 to A8, inclusive, are connected with said bosses by suitable couplings. A space J is provided be tween the tube-supporting plate J and the valve-plate I, which constitutes a distributeeass ing-chamber, into which the oil is fed from the receptacle A when the Valve-plate is turned in proper position and from which the oil is directed through the several oil tubes or ducts to the several bearings. The inner face of the tube-supporting plate J is provided between the oil-openings j? therein with a plurality of radial raised ribs js, which divide the d istributing-chamber J into iive compartments, one for each openingj2. This construction insures that all of the oil which passes through either of the openings a when one of the openings t' of the valve-plate is brought into register therewith will be directed through the proper oil-openingjLJ in the tubesupporting plate, and thereby insures'that a practically uniform quantity of oil will be de livered to each bearing in the successive 0perations of the device.

The upper face of the valve-plate I may be suitably faced for contact with the lower face of the bottom A of the receptacle A, whereby said valve-plate may in itself constitute the closure for the discharge-openings a in the bottom of said receptacle; but I prefer, for the sake of economy in manufacturing the device and also to provide for an economical maintenance thereof,to interpose between the said valve-plate and the bottom of said receptacle a yielding gasket M, which is made of a size to fit closely within the upwardly-fiar ing iiange I of the valve-plate and is provided with an annular series of openings m, adapted to register with the openings 7l in the valveplate. With this construction I am enabled to provide a perfect bearing between the contact; faces of the gasket and the bottom of said receptacle without the necessity of accurate machine-work and am enabled also to renew the bearing parts of the valve mechanism at the expense only of providing another gasket, which obviously can be supplied at a much less cost than the valve-plate I. Said gasket may be made of leather or suitably-prepared fiber. The gasket is held from rotation with respect to the valve-plate by means of a lug i4, projecting from the flange t2 and entering a notch in the inner margin of said gasket. The plate I and gasket obviously together constitute a valve-plate and are in the claims hereinafter so termed.

As before stated, the various bearing parts of the windmill require varying quantities of oil, and to effect this result I make the openings m in the gasket of varying sizes. In the present instance three different sizes of openings are provided, as shown in Fig. 6, the two connected with the tubes leading to the bearings of the shaftE being made the largest, the two connected with the tubes leading to the bearings of the shaft E3 somewhat smaller, and the one connected with the tube leading to the wrist-pin bearing being the smallest. The openings a and c' in the receptacle-bottom and valve-plate are made of equal diameters. Obviously the same result withrespect ICO IIO

to thevariable supply of oil to the bearings may be secured bymaking the openings in the bottom of the receptacle of varying sizes.

. The valve-plate l is provided Witha radially-extending rigid arm 12,by which the plate is turned or oscillated.V I n the normal position of the valve-plate `the openings z" thereof are out of line vviththe openingsa inj the bottom of the receptacle, as shown in Fig. 3, and the extent of movement of the valveplate is such that the openings of thevalveplate are brought into register with and pass same When released, and said openings i in" the return movement of the plate are againA brought into register with the openings d,

thereby bringing said openings t' and a into register twiceduring each complete operation In order to limit or (leterminethe arc of movement ofthe valve-' plate, said plate is provided at one side thereof the valve-plate.

of (on the side adjacent toitsactuating-arm, as herein shown) with a short stop-arm?, which is adapted to engage stop-1u gs A2 A2 at each end of the travel of the valve-plate, as clearly shown in Fig. 2. As before stated, said tube-supporting plate J is non-.rotatively supported on the stud A2 and does not therefore turn or rotate With the valve-plate. For this purpose said plate is keyed on the stud, as shown in Fig. 7, the keyja permitting the plate to move endwise of the stud, andtherefore to transmit the pressure of the spring K to the valve-plate tohold the same against its seat on the lower face of the receptacle A, While preventing said plate from turning `on the stud. A

Means are provided which are operable from the foot or base of the towerfor actuating vthe valve mechanism described, said means being constructed as follows:

N designates a'bellcrank .lever which is pivoted at its angle on a stud n, projecting from the base-plate B on the side thereof remote from the oil-receptacle A. Said baseplate is provided with an opening B', through' which the valve-plate-actuating arm l2 passes, as shown in Fig. 2. One arm of said bellcrank lever is connected by a link O with the outer end of the valve-plate-actuating arm l2, said vactuating-arm for `thispurpose being provided With an aperture for engagement with said link. The other arm of said bellcrank lever is fashioned to receive an extension-bar N3, made, preferably, of Wood and attached to said arm in any suitable manner. Said extension-bar N3 is connected at its outer end with an operating cord or cable P,

Whichis attached at 011e @11d t0 21,10.; at the outer end of thealrm B2 on the base-plate B and at'itsother end tothe outer end of the valve-plate-actuating arm l2. With this construction it Will be seenthat when the outer end of the extension-bar N8 of the bell-crank lever sdepressed it acts through the link O and arm A? to rotatethe valve-platel against the action ot' the spring Q', the movement of `said. plate being arrested by contact' ofthe stop-arm I3 with one of the stop-lugsAand the openings/ll and a in suchmovementbeing brought into register to permit a quantityof oil to dropintoeach of the compartments of thedistributing-chamber J. When the cable l?y is released, thespring Q acts to return said valve-plate and to again in such return movement bring said openings a i into register, whereby a further quantity of vo il is fed to said distributing-chamber. The return movement of the plate is arrested by contact of the stop-arm I3 with the other of the stop-lugs A2. Theextensionbar Ns of the bell-crank lever Willbe in practice depressed byaquick even movement and when relievedfis returned in aboutthe same time, so that itis possible by giving attention to this detail to `insure lthat a practically uniform quantityof 'oil will be fed'to the bearing inthe successive operations of the device. By operating the valve mechanism With'a slower movement than usual a greater quantity of oil may be` fed to the bearing as desired.

The device may be provided Wit-h any de sired. number of ltubes or ducts for oiling the number of bearings required, itbeing only necessary to increase the diameter ofthe receptacle in order to provide space for additional'dischargetubes. Blurtherrnorehould it be desired to use a number of tubes less than the nu mberof discharge-openings in the receptacle and the openings in the valveplate and tube-supporting plate the device may be readily adaptedv to the less'number of bearings by employing a gasket "which is apertured to correspond withthe number of bearings to be oiled, theopenin gs in the valveplate not required in such case being covered and closed by the gasket.
