LEAF SPRING LUBRICATOR.

APPLICATION FILED APR. 16, 1915.

Patented July 27, 1915.

SAMUEL T. EASTER AND COOK, OF ABERDEEN, WASHINGTON.

LEAF-srmrie nunnrca'ron.

Specification of Letters Patent. Patented J 111) 27, 1915.

Application filed April 1 1915. Serial No. 21,327.

To all whom it may concern:

Be it known that we, SAMUEL T. EAS'I'ER and ERNEST E. COOK, Citizens of the'United States, residing at Aberdeen, in the county of Chehalis and Stateof Washington, have invented certain new and useful Improve ments in Leaf-Spring Lubricators, of which the following is a specification, reference r 1 are provided on either one or both sides being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in.means or devices for use in lubricating leaf springs of automobiles or other vehicles, and the invention has for its primary object a simple, durable and efficient construction of device of this character whereby the lubricant may. be readily applied to the leaves and diffused.

A further object of the invention is to provide an improved leaf spring lubricator which is so constructed and arranged that itwill not only serve its primary function as a lubricating device, but which 'will also serve the additional function of holding the tions of the parts that we tion, reference is to be had'to' the following:

leaves in proper alinement with each other, whereby all clips or similar devices may be done away with. And the invention also aims to generally improveand simplify de vices of this character so as to render them more useful, convenient and commercially desirable. 1 I

With these and other objects in view, as will more-fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinashall hereinafter describe and claim. 1 l

For a full understanding of the invendescription and. accompanying drawing, in which, c

Figure 1 is a side elevation of a leaf spring provided-with the improvements of our invention. Fig. 2 is an inverted perspective view of a portion of one of the leaves. Fig. 3 is a fragmentary perspective view of one of the leaves-looking atthe upper face thereof. Fig. 4 is a fragmentary transverse section of two of the leaves, and Fig. 5 is a transverse sectional view of a modified form of the device hereinafter spe; cifically referred to.

Corresponding and like partsare referred to in the following descri tion and designated in all of the views o the accompanymg draw ng by like reference characters.v

Referrmg to the drawing, the numera 1 designates the superposed leaves embodying an automobile or similar spring, and2 desigwith upwardly projecting tubular portions4 7 designed to receive the discharge ends. of-

the oil cans or the like, and comnrunicating at their lower ends with ducts 5 1n the oil receiving devices, said ducts opening into the lower faces of the leaves and'there communicating with transversely extending grooves 7 formed in said faces.

From as much of the description as has preceded in connection with the correlated views of the accompanying drawing, it will be clearly understood that when the oil is applied to the oil receiving devices 3, 'it will flow down through the ducts 5 and across the grooves 7 and thence "be diffused between the adjoining faces of the leaves, whereby the leaves. will be effectively lubricated and all squeaking and the like obviated. In the preferred arrangement of the pa-rts,.the oil receiving devices 3 are arranged in pairs, one foreach leaf with the exception of the lowermost one, the two oil receiving devices of each spring being 10 cated respectively on opposite sides of the bolt or fastening device 9., and preferably all of the oil receiving devices are locatedon the corresponding side edges of the leaves, namely, the outer side edge'whereby they will be easily accessible and the oper-' ation of oiling the leaves thereby facilitated. But it is to be understood thatthe invention is notlimited in this regard and that various changes may be made in the construction, arrangement and proportions of the parts without departing from the scope of the invention as definedin the appended claims..- For example, if desired, the'upperrnost leaf alone may be provided with oilreceiving devices, as clearly illustrated in'Fig. ,5, and.

the entire spring will thereby be lubricated. Various other changes will suggest themselves to the designer, and still be within the scope of the invention.

,devices 3 f each leaf extend above the adjoining 'side edge of the next superjacent leaf, the oil receiving devices will subserve the additional funiition of holding the leaves in alinement and all clips or similar fastening devices can be done away with. Preferably, the main lug-like body portions of the oil receiving devices directly serve this purpose, as their upper faces extend above the plane of the leaf to which they are at tached or of which they form a part, so as to produce shoulders 9 against which the side edge of the leaf above will bear. Preferably the lowermost pair of oil receiving devices 3 extends slightly below the adjoining side edge of the lowermost leaf so as to engage against the side edge of the leaf and prevent disalinement of this lowermost leaf with relation to the superjacent leaves.

It is to be understood that wherever the word oil is used in the specification and claims, it-is intended-to be comprehensive enough to cover not only freely flowing oil, but all other substances or ingredients that can be used as a lubricant.

What is claimed, is: L

1. A spring embodying a plurality of superposed leaves, and oil receiving devices carried by said leaves, the oil receiving devices of the respective leaves engaging the oil receiving devices carried by the respective leaves on opposite sides of said bolt, said oil receiving devices projecting laterally from the leaves and formed with ducts opening into the lower faces of the leaves, the oil receiving devices being provided with shoulders abutting against the side edge of the next adjacent leaf.

l. A spring embodying a plurality of superposed leaves and oil receiving devices carried by said leaves on the side edges thereof, the oil receiving devices on the leaf next to the lowermost leaf projecting below and in contact with the side edge of the leaf next below all of said oil receiving devices of the respective leaves projecting above and in contact with the side edges of the leaf next above.

In testimony. whereof we hereunto affix nesses.

SAMUEL T. EASTER. ERNEST E. COOK.
