CRANK PIN OILER.

SPECIFICATION forming part of Letters Patent No. 296,214, dated April 1, 1884.

Application filed October 17, 1882. Renewed February 21, 1884. (l\ o model.)

ib- (tZZ 1072,0111, it may concern.-

Be it known that 1, CHARLES H. PARSHALL, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in Crank-Pin Oilers; and I do declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification. This invention relates to certain improvements in that classof lubricators which are employed to lubricate crank-pins, and has for its object to provide a novel combination and arrangement of parts whereby the oil is delivcred from a reservoir to a transparent chain.- bcr located outsidethereof, through which the oil passes in visible drops, the transparent chamber being attached to and supporting a neck or tube which connects with flexible tubes for supplying the lubricant to the crankpin.

The object of my invention I accomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a crank-pin lubricator embodying my invention; and Fig. 2, a modification, which will be hereinafter explained.

In carrying out my invention, A represents any suitable reservoir for the oil.

B is a crank-pin to be oiled.

G'is any stationary support. I

D is a flexible metallic connection between the cranlr-pin and the reservoir. This flexible connection may be in the nature of a telescopic arrangement of tubes D and D one operating within the other as the crank operates, as shown in the drawings; or, as shown in thevariation, the tube may be made in the nature of an elbow-j oint which straightens out -as thev crank recedes and doubles up as it advances.

E is a water-chamber, made of glass or other transparent medium. It is so located outside of the oil-reservoir and between the reservoir and the flexible tubes which. connect with the crank-pin that the oil, as it leaves the reservoir, rises through the water in visible drops, thus indicating the rate of feed. Instead of being a water-chamber, however, this might be atransparent air-chamber and the oil be caused to drop down through it, it only being essential that the chamber should be transparent.

The neck d, which connects the transparentohamber with the flexible metallic connection, may be of any desired length. It may, as shown in the drawings, be such as to locate the reservoir close to the crank; or the reservoir may be located in any other place and the oil be carried thence to the transparent chamber E, and thence to the flexible connection, and so to the crank-pin.

If the device is of the telescopic form shown in the drawings, it will operate more or less in the nature of a pump, and in that event there should be a valve, F, located at the top of the transparent chamber. So alsol prefer, generally, to employ a valve, G, for regulating the flow of oil. A lubricator of this character will be found to be very effective in its operation, while the supply of oil is kept uniform and the reservoir is at all times accessible for refilling, cleansing, 850.

It is apparent that at the top of the flexible tubes, where they connect with the waterchamber or with the pipe leading therefrom, there is provided a flexible joint, so as to conform to the movement of the crank, andasimilar flexible connection is made at the point where it is united to the crank-pin.

Heretoforean oil-reservoir has been connected with-a crank-pin through the medium of telescopic tubes, and in another instance alubricator for steam-cylinder chests has been provided with a transparent chamber through which the oil is fed in visible drops; but, so far asI am aware,acrank-pin oiler has never combined in its structure astationary oil-reservoir, flexible metallic tubes connecting the reservoir with the crank-pin, and a transparent chamber located between the oil-reservoir and flexible metallic tubes, such combination effecting a new result, and requiring an adaptation or organization of parts for effecting such result.

What I claim is- 1. A. crank-pin lubricator combining in its structure the following elements, to wit: a stationary oil-reservoir, a transparent chamber located outside of the reservoir at the side of the same, and connected therewith at one end, and flexible metallic tubes connected with the other end of the transparent chamber by a j oint, the said chamberbeinginterposedbetween the reservoir and the upper portion of the tubes, substantiallyas and for the purpose described.

2. The combination, substantially as hereinbefore described, of a stationary oil-reservoir, a transparent chamber located outside of but adjacent to the side of the reservoir, and connected at one end with the latter, a neck or
