SPRING-orma.

Specification of Letters Patent.

Patented May 11, 1920.

Application filed February 15, 1917. Serial `No. 148,761.

To all LU/Lola t may concor/n.'

Be it known that I, IVILLIAM I-IIRAM l'SnowN, a citizen of the United States 0f America, and a resident of Cleveland, county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Spring-Oilers, of which the following is a full and clear specification.

This invention relates to that type of oilers employed on multi-ply leaf springs, and the object of the invention is to provide a siinple forni of device which be readily applied. to the spring and which will efficiently supply oil to the edges of the spring, whence the oil will be worked into the spaces between the leaves by the independent sliding action of the leaves upon each other in the well known manner.

In the drawingd Figure l is a side elevation of a portion of a spring provided with my device;

Eig. 2 is a perspective view of the device detached Eig. 3 is a vertical longitudinal sectional view; and

Fig. et is a vertical sectional view showing another way of applying the device to the spring.

The device consists of a clip preferably forme-d of sheet instal and embodying a top plate l and depending side plates 2, these latter plates being provided with inwardlyturned flanges 3 along their lower edges adapted to engage under the lower side of the spring, the distance between the depending side plates 2 being `iust sufficient to receive the spring between them.

The depending side plates 2 form, in connection with depending flanges t at the ends of the top plate, a chamber for holding a lubricating pad 5, which pad is adapted to absorb the lubricant and gradually feed it down to the opposite sides of the spring, the motion of the vehicle serving to agitate the pads sufficiently to bring about this gradual feed. A hole 6 is forined in the pad and the top plate 1 is provided with an oil-hole 7 through which oil may be fed to said hole 6, which hole serves as a reservoir or retainer for the oil until it is absorbed by the pad. The hole 7 may be closed by any suitable device, such, for instance, as a rotatable plate 8 pivoted to the top face of the plate 1. The depending side plates 2 are tapered in width toward one end of the device to correspond with the taper of the body of the spring.

This device may be applied to a spring by slipping it over the narrow or outer end thereof and then sliding it along the spring until it comes to that part of the spring which it fits. lVhen thus adjusted in place, it will tend, by gravity, to hold itself in place, but, in order to prevent the device from being accidentally slipped outwardly along the spring and jarred or knocked oil' and thus lost, I provide the side plates 2 with a pair of outwardly-extending eyes 9 through which a wire may be passed to tie the device to the spring, if desired.

I have shown the device applied to an upwardly bowed spring, in which case gravity will tend to hold the device in place, as stated, but when it is applied to a down wardly bowed spring, the device will be so located as to be held against slipping down toward the narrow end thereof by the usual rebound clip. Instead of applying the device to the spring by slipping it over the narrow end of the spring and sliding it along the spring, it will be obvious that the side plates may be sprung apart sufficiently to vapply the device to the spring at the point where it is intended to lit the same. It will be obvious also, as shown in Fig. 4, that the device may be applied to the spring so as to cause the pad to press against the side edges of the leaves of the spring.

The scope and nature of the invention having been thus indicated and its preferred embodiment having been specifically described, what is claimed as new is:

l. In an oiler of the type set forth, a clip adapted to extend over three sides of the spring and provided with an oil absorbing and delivering pad in its one side, said pad being provided with a recess to serve as an oil container the lower extended edges of the side plates of the clip being provided with inwardly turned flanges engaging the opposite side of the spring from said pad whereby it is held in position on said spring, said pad being adapted to rest against one side of the spring and a wire secured around said clip and said spring as an additional support for said clip.

2. In an oiler of the type set forth, a clip adapted to extend over three sides of the spring and provided with en voil absorbing said pad being adapted to rest against one Aend delnrering pad in its one side said pad side of the spring. 10 being provided with a recess to serve as an In testimony Whereofl hereunto .eix my oil Container the lower extended edges of signature.

the side plates of the olip being provided WTILLIAM HIB-AM BROWN. with inwardly turned .flanges engaging the lVitnesses: opposite side of the spring from said pad G. M. ODONNELL,

whereby it is held in position on said spring v A. G. MILLER.
