SHEAVE-LUBRICATING- DEVICE.
Specification of Letters Patent.
Patented May 25, 1915.
Application filed March 31, 1914:. Serial No. 828,582.
To all whom it may concern: 7
Be it .known that I, MATHEW MULHOL- LAND, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and
State of Ohio, have invented a new and useful Improvement in Sheave-Lubricating Devices, of which the following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.
My invention relates to sheave-lubricating devices, its object being to provide means whereby the grooves of sheaves may be antomatically and economically lubricated in order to reduce the frictional action which takes place between the chain or rope which passes over said sheave.
The said invention consists of means hereinafter fully described and particularly set forth in the claims.
The annexed drawing and the following description set forth in detail certain means embodying my invention, the disclosed means, however, constituting but one of various mechanical forms in which the principle of the invention may be applied.
In said annexed drawing: Figure 1 represents a plan of a lubricating device embodying my invention, showing the sheave itself in horizontal section. Fig. 2 represents a side elevation of the sheave, showing a fragmentary portion of a chain passing over same, with the oil receptacle in vertical longitudinal section. Fig. 3 represents a vertical transverse section of my improved device. Fig. 1 represents a vertical central section of the sheave taken at right angles with the axis thereof. Fig. 5 represents a detail section taken upon the plane indicated by the line VV in Fig. 2 and viewed in the direction indicated by the arrow.
The illustrated embodiment'of my invention comprises an oil receptacle 1 provided with a semi-cylindrical central portion 2 and end extensions 3 which are upwardly inclined away from the central portion 2, as shown in Fig. 2. The central portion of the extensions are formed with semi-cylindrical grooves 4 and downwardly inclined side walls 5, as shown in Fig. 5. These downwardly extending extensions and grooves formed therein, lead any oil which may drip from the chain, back into the central or wall portion 2 of the receptacle. The bottom of the latter is provided with a tapped opening 6 normally closed by means of a plug 7 by means of which the contents of the receptacle may be drained.
Soldered or otherwise secured to the central portion of the sides of the receptacle 1 and adjacent to vertical slots 8, Fig. 1, are two castings 9, each forming vertical guide-ways 10 for the reception of the hangers 11 which are secured to suitable stationary supports 12. The upper ends of these hangers are preferably provided with threads upon which are mounted the nuts 13, by means of which,'it will be seen, the vertical position of the hangers may be varied, as desired, within certain limits. The lower ends of these hangers support a journal rod 14 upon which is mounted'the hub of the sheave 15. The position of the hangers is such that the lower portion of the sheave projects into the cylindrical or well portion 2 of the receptacle 1, and the latter is filled with the desired lubricating oil, as shown in the drawing.
Adjacent to the groove 16 of the sheave and in the body of the latter are formed a plurality of pockets, 17 as shown in Figs. 3 and 4. These pockets are completely inclosed except for an outlet 18 with which each is provided, said outlet intersecting the adjacent wall 19 of the groove and communicating with that end of the pocket which is nearest the axis of the sheave, as shown.
In the operation of the above-described device, the chain 20 passes over the sheave and through the groove in the usual manner, and the lower portion of the sheave turns in and travels through the oil, as will be readily understood. During such travel, however, the pockets become filled with the oil and raise the same upwardly out of the oil well. Upon emerging from the latter, the oil begins to discharge, but with sufllcient slowness to allow a part of same to be retained in the pockets when the latter reach the topmost point in their travel with the sheave. This action it will be seen, permits a constant discharge of oil inwardly toward and into the groove 16 and upon the chain, during the latters travel therethrough, thus supplying the necessary lubricant automatically and continuously, as required.
It will be readily understood that any desired size of opening 18 may be adopted in accordance with the conditions, the factors of revolution of the sheave and the viscosity of the oil or lubricant used.
Having fully described my invention, what I claim and desire to secure by Letters Patent is 1. In a sheave-lubricating device, a sheave provided with pockets each having an outlet intersecting the side Wall of the sheavegroove, said outlet being intermediate of the closed end of the pocket and the axis of the sheave.
2. In a sheave-lubricating device, the combination with an oil receptacle; of a sheave mounted so as to have its lower portion project into said receptacle, said sheave being provided with pockets, each having a lateral outlet intersecting the walls of the sheave-groove.
3. In a sheave-lubricating device, the combination with an oil receptacle; of a sheave mounted so as to have its lower portion project into said receptacle, said sheave being provided with a plurality of cavities,
Gopies 01 this patent may be obtained for five cents each, by addressing the Gommissioner of Pate-nts,
an unobstructed groove for the reception of achain or cable, and mounted so as to project into said receptacle; said sheave being provided with pockets for elevatingthe oil from the latter.
Signed by me, this 28th day of March, 1914.
