SPRING-onine f DEVICE.

Application inea m1152271,

To all yw/wm t may concern.'

Be it known that I, MILEs F. MOORE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Spring-Oiling Devices, of which the following is a specifica tion.

This invention relates to improvements in spring oiling devices, and has particular reference to means for lubricating the leaves of an automobile spring. It is obvious, however, that the same might be used in similar springs other than those employed upon motor vehicles.

The principal object of this invention is to produce a simple container for a lubricant, and to further provide means for feeding this lubricant to the leaves of a spring so that the same will gradually work between the leaves, thus preventing excessive friction thereby prolonging the life of the spring.

A further object is to produce a device which is simple in construction, neaty in appearance and one which may be readily ap-r plied to the average automobile, without altering the construction of the same.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts 'throughout the same,

-Figure 1 is a perspective view of my device,

Figure 2is a side elevation of a spring having my device applied thereto,

Figure 3 is a vertical cross section of the preferred form of my device shown in Figure 1, y

Figure 4 is a fragmentary detail view of the filling well,

Figure 5 is a. plan View of the blank out of which my device is formed, and

Figure 6 is a vertical cross section ofthe modified form of my device.

Applicant is aware of the fact that devices have been applied to springs for the purpose of forcing a lubricant between the leaves thereof, such as wedges having a passageway therein for the grease. These devices, however, are cumbersome, hard to manipulate and do not feed a steady amount,

but only small quantities of lubricant, wherelarge quantities of lubricantare essential in order to secure the proper lubrication.

,lin the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 5 designates the ordinary leaf spring, while the numeral 6 designates the body of my device as whole.

By referring to Figure 1, it will be noted that my device comprises a bottom portion 7, and upwardly extending portions 8 and 9. This bottom portion forms a reservoir 11 within which the lubricant is placed.

A filling well isshown at 12 has a cap 13 normally held closed by a spring'k 14 (see Fig. Ll). The upwardly extending portions 8 and 9 are channel-shaped and each section contains a wick as shown at k16 and 17, re-

spectively. These wicks have their lower ends extending downwardly and into the reservoir 1l and have their upper surface 1n contact with the sides of the leaves of the `spring as best shown in Figure 3.

A cover 18 closes the reservoir 11, and also contacts the under-side of the spring 5. It will be observed thaty the cover has formed integral therewith side members 18 which are curved at their extremities. The sides of the cover assist in positioning the wicks in the portions S and 9 and each curved `extremity retains the end of each wick at a substantially right angle to the body of the wick, ythereby affording a more positive capillary attraction than could be had if all of the rbody "of the wick were in the same plane. A top Lplate 19 has a downwardly extending spring 21 secured to its under surface. This top plate is attached to the upA wardly extending portions 8 and 9 las by cotter pins y22 and 23.

By referring to Figure 6, it will be noted that the construction is substantially the same as that shown in Figure 3, with the exception that the reservoir is placed above the sprino as shown at 211 and that the wicks extend from this reservoir downwardly along the sides lof the spring. In this form I providea filling opening 26 which is closed by, a suitable. cap. yThe retaining means for this e form of lu'bricator` consists of a bottom plate 27, similar to the yplate 19, to which a spring l 28 is secured, which spring contacts the under-side of the leaf spring to be lubricated.

Theplate 27 is secured to the device by Cotter-pins in a lmzinner similar to that described in the .preferred form.

It is to be understood that the form of my invention herewith shown and described is to be taken vas a preferred example- 'ofthe same, and that various chengesin the shape, size and arrangement of parts may be Iesorted to Without departing romthe spirit of the invention or the scope of the snbjoined claim.

Having thus described(y my invention, I clziimz.- 1

The combination with alea spring, of

a device for lubricating the surfaces between the leaves, comprising zt lubricant holding receptacle, Wick-holding channel portions formed integral with the receptacle'7 a cover for the receptacle including side members `terminating in -curved extremities for` lpositioning the ends of the Wicks in the receptacle, a top plate secured to the extremities of the channel portions, and a spring secured tosa id tropV plate Jfor engaging the leaf spring.

In testimony whereof I affix my signeture.
