a plication filed September 19, 1917. serial No. 192,115.

and State" of Wisconsin, haveinvented certain new-and useful Improvements in Oil Distributing Mechanisms; and I do hereby declare that the following is a full, clear and exact description thereof.

My invention refers to new and useful improvements in oil distributingmechanisms particularly adapted for use in connection with motor-cycle engines. 7

1n motor-cycle engines, as in other types of internal combustion engines, it hasbeen found that the moving parts will operate much more eliiciently if they are provided with a positive lubricating system for feeding oil thereto at predetermined intervals. The feeding of such lubricating fluid is carried on most effectively by forcing oil under pressure to the parts where needed, even though such pressure is only slightly above that of the atmosphere.

Therefore, it is primarily the object-of the present invention to provide a simple and improved oil feeding mechanism which will positively feed a predetermined amount of oil under slight pressure to the point where most needed.

A minor object of the invention is in providing means for regulating the amount of lubricating fluid fed to said moving parts of the engine.

I A still further object is to provide a simply constructed and compact oil distributing mechanism, which can be attached to the outer side of the gear casing of a motor-cyclepower plant.

With the foregoing and other objects and advantages in view, the invention consists in certain novel features of construction, combination and arrangement of parts which will be hereinafter more particularly described and claimed, and shown in the drawings wherein V Figure 1 represents a vertical, transverse, sectional view through an oil distributing mechanism constructed inaccordance with my invention, said section being'taken substantially on the plane of the 11118 1-1 of of the l'ine 2'2 of Fig. 3.

-Fig, 3 is a verticallongitudinal section on the plane of the line 3-3 ofhig'; 2, and Fig. 4 1s a detailtransverse, sectional View on the linea -e of Fig. 3..

Thepresent invention is adaptedto be secured upon the outer surface of a cover or faceplate 1 of a gear casing, such 'as-is shown in Fig. 1 ofmy co-pending'patent appl1cat1on, tie-rial No. 192,1l7,filed September 19, 1917. The operating portions of the invention are disposed in a suitable cast casing or housing 2, which consists of a substantially horizontal, elongated, cylindrical chamber 3 and a chamber 4 of shorter length and larger diameter depending from the bottom of the first chamber, the axis of the chamber 4- being disposed at right angles to that of the first mentioned chamber. The chamber 3 is adapted to bedisposedjparallel to the face plate 1, while a threaded nipple 5 on the inner end of the chamber l is adapted to be disposed through an opening in said face plate and receive a jam nut 6, whereby the casing 2 will be held in operative position. lhe means for attaching the casing is particularly shown in Fig. 1.

The top of the chamber 3 adjacent one end is provided with an inlet 7 into which oil is fed by gravity from a suitable reservoir carried by the motor-cycle, and directly below said inlet and alined therewith is an outlet port 8 through which oil is forced from the chamber 3 under slight pressure. The lower end of the port 8 opensinto a sight feed reservoir 9, which reser voir is cast integrally with the chambers 3- and t, as mostclearly shown in Fig. 3. The outer end of the cavity which forms the reservoir 9 is shouldered as at 10, and internally threaded to receive a gland 11 between which and said shoulder 10 is disposed a transparent glass plate 12. An opening 13 extends from the bottom of the sight feed reservoir through which oil flows therefrom to the parts to be lubricated.

' Referring more particularly to the means for discharging the lubricating fluid from the chamber 3, the numeral 14: designates the cylindrical cavity within said chamber 3 in which is rotatably mounted a cylindrical llatenteddani 29., 19th, I

fluid receiving member or valve plug 15, said plug being held in said cavity by a closure cap 16 threaded in the open end of the chamber 3, theother end of the latter being closed by a wall 17. In Fig. 3 it will be noted that the valve plug 15 is considerably shorter than the length of the cavity ll of the chamber 3 and is spaced from the wall 17 thereof, this spacing arrangement being procured by a pin 18 which extends from said wall and abuts the adjacent end of the plug 15. r V

This space between the end of the valve plug and the wall 17 provides room for a pivotally mounted cam plate 19, which has a central opening to receive the pm 18. One edge, preferably the lower one, of the cam plate is notched, as at 20, to receive a pivot pin 21, which PIO1QCtS. through the wall of the chamber 3, as shown in Fig. 4.

The portion of the cam plate remote from the pivot pin 21 is readily shifted by 1nward and outward movement of the adjusting set screw 22 threaded through the wall 17. as shown in the last mentioned figure.

The cam plate 19 is adapted to provide mean for causing the reciprocation of an oil expelling plunger 23, which is in the form of a cylindrical rod and is disposed in a cylindrical bore 241 formed in the valve plug 15 to one side of the IOttttlVGflXlS thereof. The bore extends from that end of the valve plug, which is adjacent the cam plate shaft 29 keyed thereto.

14 to a point spaced from the opposite end where it extends laterally and opens through the side of the plug, as shown at 25. A coil spring 26 positioned between the end of the bore 24 and the inner end of the plunger 23 forces the-latter outwardly so that its outer end will continuously engage the cam plate 19.

It will now be seen that if the valve plug 15 is rotated, theplunger 23 will be reciprocated within its bore 24, it being moved in one direction by the tension of the spring 26 and in the reverse direction by engagement with the cam plate. Any prefered means may be employed for rotating the valve plug, but the stub shaft 27 of one of the gears 28 of a gear train within the gear casing closed by face plate 1 is arranged so that said gear 28 can readily have a worm V This shaft 29 is journally mounted in a sleeve 30 positioned within the chamber 4 in which it will be caused to rotate as the train of gears revolve.

. Fixed on the shaft 29 so as to move therewith is a worm 31, the teeth of which are adapted to extend through an opening connecting the chambers 3 and 4. to mesh with gear teeth 32 cut in the periphery of the move the plunger 23 about the axis of the latter, such movement causing the plunger to reciprocate, as hereinbefore mentioned.

Although the operation has probably already been made sufliciently clear by the description of the various parts, it may be briefly set forth as follows:

As the lubricating fluid is continuously flowing from its source of supply into the inlet 7, it will be seen that upon each rotation of the valve plug 15 oil will be received in the bore 2411s the inlet 25 thereinto is alined with said inlet 7. When this intake of oil is taking place the portion of the bore 24: unoccupied by the plunger 23 will be greatest, inasmuch as said spring 26 will have forced said plunger outwardly to its greatest extent, its extreme outward movement being permitted by the positioning of the cam plate 19. After the inlets 7 and 25 are moved out of alinement, the plunger 23 begins to move toward the end of the bore 24: so that by the time the inlet 25 of the bore 24 alines with the outlet 8, the oil in said bore will be somewhat compressed to thereby procure a quick discharge of the lubricating fluid from the valve plug to said outlet port 8. This movement of the parts is repeated upon each rotation of the valve plug by the worm 31.

7 It will be obvious that this mechanism will operate very efficiently during the operation of the engine with which it is adapted to be used, but when the movement of the parts of the latter cease, the flow of oil from the oil reservoir will be automatically stopped as the valve plug 15 will cut oit the discharge between the ports 7 and 8, which, under working conditions, are only intermittently connected through the medium of the oil receiving bore 24. Various minor details in shape and construction, as well as in the mode of operation of the several parts may be. accomplished without departing from, or sacrificing any of the principles of the invention.

I claim I A distributing mechanism comprising a casing open at one end and closed at the other, a fluid receiving member rotatably mounted in the casing and spaced from the closed end thereof, said member having a longitudinally extending bore disposed to one side of its rotative axis, a plunger slidable in said bore and projectable beyond one end of the member, means for closing the open end of the casing, a pin extending inwardly of the closed end of the casing and engaging the end of the member to hold the same spaced therefrom, a circular cam-plate disposed in the casing between the closed end thereof and the adjacent end of the member to be engaged by the projecting end of the plunger, one portion of the edge of said plate being provided with an open end slot,

naua ve'e said plate also having a central circular opening of greater diameter than said pin for receiving the same, a pivot pin extending transversely of the casing between the end thereof and the adjacent end of the member, said pivot pin being slidably dis posed in said open end slot, a set-bolt threaded through the end of the casing for engagement with one side of the cam-plate at a point remote from said pivot pin, whereby it) to rock the same on said pin, and means for revolving the member.

In testimony that I claim the foregoing l[ have hereunto set my hand at lMlilvvaukee in the county of Milwaukee and State of 15 Wisconsin.
