SPRING-OILER.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Application filed April 9, 1917. Serial No. 160,774.

To all whom it may concern.

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

The object of this invention is to provide an extremely simple oiling device which may be readily attached to the usual rebound clip or to a special clip attached to the spring, the construction being such that the appliance may be attached to springs of various widths.

In the drawing Figure l is a plan view of a portion of a leaf spring showing the application of my device thereto;

Fig. 2 is a side elevation thereof;

Fig. 3 is a section through the oil receptacle on the line 33 of Fig. 1;

Fig. at is a horizontal section through the oil receptacle on the line 4-4 of Fig. 2, looking upwardly at the under side of the cover; and

Figs. 5 and G are perspective views of modifications.

Referring to the drawing annexed, a designates the usual rebound clip, and b designates the side arms of a spring wire bail whose free ends are anchored to the upper end of the rebound clip by being provided with eyes 0 which are clamped against the outer faces of the upright bars of the rebound clip by means of the head and nut, respectively, of the pivot bolt (Z of the rebound clip. The connecting member a of the bail carries the oil receptacle 7, which, in the present instance, is a circular box having fitted down over its upper open side a cover 9, coincident openings it being formed in the cover and the body of the box for the egress of oil. these openings being located at a point above the normal level of the oil. so that the feed of the oil through the openings will be a splash feed. The oil receptacle is pivotally mounted on the cross-bar e by having said cross-bar extend through the openings h from one side of the box to the other. A suitable filling opening is provided in the cover of the receptacle and this opening is kept normally closed by means of plate i provided with a convex upwardly-projecting part j which fits up into the filling opening, said plate being formed of bent spring metal having its end riveted to the under side of the top at 70. I

It will be observed that the jouncing action the spring receives while the vehicle is in motion on the road will agitate the oil in the receptacle sulliciently to splash the oil into the openings h, whence the oil will run down the sides of the receptacle and the side edges of the spring, from whence it will seep into spaces between the contacting faces of the leaves of the spring. Preferably, the width of the oil receptacle is such and the oil exit openings h are so arranged that the oil will run directly off the sides of the re- 1 ceptacle onto the sides of the spring, Whereby very litle, if any, of the oil will be allowed to collect on the top side of the spring. It will be observed that it is desirable that the receptacle shall rest upon the spring, so as not only to be directly jounced by the action of the spring, but also to deliver the oil directly from the sides of the receptacle onto the sides of the spring. The holes h are, of course, slightly larger than the diameter of the connecting bar 6, so as to allow free escape of the oil. It will be observed also that in the specific construction shown, the bail serves to lock the cover on the receptacle, thereby rendering additional or extraneous fastening devices unnecessary.

It will be observed also that a very important feature of the form of the device shown in Figs. 1 to 4 lies in the idea of connecting the oil receptacle to the spring by means of a pair of bars which may be readily bent inwardly toward each other or outwardly away from each other, thereby permitting this device to be readily adapted for attachment to springs of various widths. This construction also, as will be seen. lends itself very nicely to the attaching of my device to the usual rebound clip of the spring, it being possible to attach the device to the clip by simply inserting the usual bolt cl of the clip through the eyes 0 at the ends of the attaching arms.

' It will be observed from an inspection of Figs. 5 and 6 that I may anchor the receptacle by means of a single side arm or member instead of a pair of such members. as shown in Figs. 1 to at, inclusive. In this case, it will be desirable to make the anchoring arm a little stiffer than in the form of the device where two of such arms are employed. As shown in Fig. 5, this arm may be of stiff wire, or, as shown in Fig. 6, it

may be a flat plate which is attached to the receptacle by riveting it to the exterior of the receptacle. When this flat plate or bar is used, it will be desirable to provide the plate with a depending piece Z immediately in line with the oil-discharge opening, so that the oil will run down over the exterior of the plate and thence to this depending piece and thence to the side of the spring, thus constituting with the anchoring memher a means for delivering the oil from the receptacle to the side of the spring. This oil delivering or conducting device may be embodied in the form of device shown in Figs. 1 to a by attaching it directly to the cup, this being shown at Z in Fig.

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

1. The combination with a leaf spring of an oil receptacle resting on the top side thereof, and means for anchoring the receptacle in position on the top side and in contact therewith, said receptacle being provided with an oil exit at a point above the normal level of the oil, the anchoring means embodying a pair of laterally-bendable arms anchored at one end tothe usual clip on the spring and connected at the other end to the opposite side walls of the receptacle at a point above its bottom.

2. The combination with a leaf spring of an oil receptacle resting on the top side thereof, and means for anchoring the receptacle in position on the top side and in contact therewith, said receptacle being provided with an oil exit at a point above the normal level of the oil, the connection to the receptacle embodying a bar extending through a hole in the side wall of the receptacle body above its bottom.

8. As a new article of manufacture, an oil cup having an exit opening at apoint above the normal level of the oil and provided with a pair of side attaching arms connected to the receptacle above its bottom and bendable toward and from each other,

the free ends of the arms being provided with eyes, and a pivot member extending through the eyes to connect the arms to the spring to be oiled.

4;. As a new article of manufacture, an oil cup provided with a cover, an oil exit opening being provided through the cover and the body of the cup at a point above the normal oil level, and a pair of attaching arms connected at opposite sides of the cup through said oil openings.

5. As a new'article of manufacture, an oil cup provided with a cover, the cover and the body of the cup being provided with coincident openings at opposite sides of the cup, a bail having side arms bendable toward and from each other, and a cross-bar extending through the aforesaid openings to thereby pivotally connect the cup to the bail and lock the cover on the cup.

6. As a new article of manufacture, an oiler for multi-ply leaf springs embodying an oil cup having a discharge opening therein above the normal level of the oil and provided with an anchoring member fastened at one end to the side wall of the receptacle and having its free end provided with a pivot bolt-receiving eye.

In testimony whereof I hereunto afiix mv signature.
