LEAF-SPRING- OILER.

Application filed August 24;, 1914. Serial No. 858,351.

vehicle springs, whereby undue friction and consequent wear of the same may be obviated. v

The invention in its more specific aspect provides a pair of oil chambers or containers, each having an extension disposed upon one side of the spring, a strip of absorbent material arranged in each of the extensions and supplied with oil from the respective chambers, said absorbent strips engaging with the edges of the spring leaves, and means for clamping the chambers securely upon the spring.

The invention has for a further object to provide a device of the above character which will constantly supply the oil to the spring leaves without waste, and thusiprevent the same from rusting, and also avoid the expense incident to the rating the spring leaves in order to apply oil thereto.

\Vith the above and other objects in view, the-invention consists in. novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which:

Figure l is a side elevation of my improved oiling device applied to a vehicle spring, Fig. 2 is a section taken on the line 2-2 of Fig. 1, and Fig. 3 is a section taken on the line 3-3 of Fig. 1.

Referring in detail to the. drawing 5 indicates generally the two sections of the oiling device. As these sections are identical in their form and construction, a detail description of one will suffice for both.

Each section includes an oil chamber 6,-

relates to an improved necessity of sepawhich is preferably of rectangular form and extends inwardly over the uppermost leaf of the vehicle spring. With the walls of this chamber on one end'thereof an arm or extension 7 is integrally formed. The inner face of this extension is provided with a channel 8 of dove-tail cross sectional form, and within the same a strip of felt, orother absorbent material, 9, is securely held. This felt strip is sufficiently thick to project slightly beyond the inner face of the extension 7, as clearly shown in Fig. 2 of the drawing, so that the same may be tightly engaged against the edges of the spring leaves. The bottom wall of the chamber 6 is provided with an orifice 10 which communicates with the channel 8 and supplies the oil to the felt strip 9. The arm, or extension, 7 has an 'apertured ear 11 formed upon its lower end and upon the opposite endof the chamber 6 withrespect to said extension an upwardly extending apertured'ear 12 is formed. Upon the top wall of the oil chamber 6 a filling nipple 13 is provided, said nipple being formed with an annular groove 14 in its periphery and an opening 15 extending transversely through the nipple and connecting with the bore thereof.

16 designates a cap preferably constructed of sheet metal and having an inwardly projecting annular rib 17 designed to seat in the groove 14 on the nipple. This cap is also provided with an opening 17 in its body wall which is adapted. to be brought into register with the opening 15 of the nipple by turning the cap thereon. Through these coinciding openings the chamber 6 may be readily filled with a suitable lubri-' eating oil, the cap 16 is then turned upon the nipple so as to close the openin 15 and prevent the escape of the oil as we 1 as the ingress of dust or other foreign matter to said chamber.

18 designates the superposed leaves of the ordinary elliptical vehicle spring upon which the two sections of my improved oiling device are adapted to be secured. Thesesections are arranged as clearly shown in Fig. 2, the chambers 6-projecting inwardly upon the top leaf of the spring, while the extension 7 extends downwardly on the opposite side of the spring. The upwardly projecting ears 12 are connected by a bolt 19 having a clamping nut 20 threaded upon one end thereof. The cars 11 'on the extension T are similarly connected by a bolt 21 upon the end of which a clamping nut 22 is threaded.

It will be obvious that by simply adjusting the

nuts

21 and 22 upon the respective bolts the two sections of the device may be tightly clamped upon the spring and the felt strips 9 engaged against the opposite edges of the spring leaves. It will be readily understood that these strips which are seturated with oil from the chambers 6 constantly apply the oil to the engaged faces of the several spring leaves 18. Thus objectionable noises incident to the frictional sliding movement of the leaves upon each other, as well as undue wear of the leaves and rusting of the same may be prevented.

From the foregoing description taken in connection with the accompanying drawing, the construction, manner of operation and several advantages of my invention will be clearly and fully understood.

The device while of extremely simple con.- struction, is nevertheless highly convenient and serviceable in practical use and may be very easily and quickly applied to or removed from the vehicle spring. By the use of the same considerable expense incident to the necessity of separating the leaves of the spring in order to lubricate the same may be avoided. It will. of course, be obvious that the device may be constructed in various sizes. and the chamber (3 of any desired ca pacity. The invention is also susceptible of a great many other minor modifications in the form, construction and arrangement of the several parts employed, and I therefore reserve the privilege of resorting to all such legitimate changes as may be fairly enrbodied within the spirit and scope of the invention as claimed.

Vhat I claim is:

1. An oiling device of the character described comprising two similar sections, each having an oil chamber and an extension formed thereon adapted for engagement against one of the edges of the leaves of the vehicle spring, the said extension being provided with a channel in its inner face in connection with the oil chamber, a strip of absorbent material arranged in said channel, and means for securely clamping the two sections of the device upon the spring.

2. An oiling device of the character described comprising two similar sections, each having an oil chamber adapted for engagement upon the upper surface of a vehicle spring, said. chamber having an integral extension provided with a channel in its inner face in connection with said oil chamber, a strip of absorbent material arranged within said channel and projecting beyond the inner face of said extension for engagement upon one edge of the spring leaves, and means for removably clamping said sections upon the spring.

3. An oiling device of the character described, comprising two similar sections, each provided with an oil chamber adapted for engagement upon the top of the vehicle spring, said chamber having an extension formed upon one end provided with a channel in its inner face, the bottom wall of the chamber having an orifice connecting the chamber with said channel, a strip of ab sol-bent material arranged in said channel and projecting downwardly therefrom for engagement against one edge of the spring leaves, said chambers being provided upon their other ends with apertured cars, a clamping bolt connecting said ears, and a clamping bolt connecting the lower ends of said extensions.

4. An oiling device for vehicle springs including an oil container provided with an integral extension spaced from one of the longitudinal edges of the spring leaves and having a channel in its inner face, a strip of absorbent material. arranged in said channel and contacting with the edges of the leaves to supply oil to the opposed contacting faces of the leaves in their relative movement, one wall of the oil container being provided with a duct to constantly feed the oil to said absorbent strip, and means for securing the container upon the vehicle springs and effecting a pressure of the absorbent strip against the edges of the spring leaves.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
