VEHICLE-SPRING LUBRICATOB.

Application filed February 12, 1917.

To all whom it may concern:

Be it known that I, Tnrooonn C. Scnor'rzr, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Vehicle- Spring Lubricators; and I do declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates broadly to lubricating devices and more specifically to those designed for use on the leaf springs of automobiles and similar vehicles.

The principal object of the invention is to provide a very simply constructed lubricatingdevice which can be very inexpensively manufactured and yet which will be extremely etlicient in operation.

A secondary object is to provide a device of this character which may be adjusted to springs of various widths.

Still another object is to provide means whereby the device may be provided with one or more reservoirs for storing a quantity of oil so that it will be unnecessary to give any attention to the device except at extended intervals.

\Vith the above and many other objects in view the invention resides in the novel features of construction and combination of parts which will be hereinafter more particularly described and claimed. and shown in the drawin wherein 1 Figure 1 represents a. vertical cross sectional view through an automobile spring having my lubricator applied thereto, the latter being shown in edge view;

Fig. 2 is a side elevation of the invention applied to a spring;

Fig. 3 is a vertical transverse sectional view on the plane of the line 3 3 of Fig. 2;

Fig. 4 is an inner side view of one of the side members of the device;

Fig. 5 is a detail perspective view of the combined]reservoir and filling member.

For the purpose of illustration this inrproved luln-icator is generally applied to an ordinary vehicle spring of conventional design composed of a plurality of leaves L. Broadly the invention comprises a pair of lubricating members 1, disposed one on each side of the spring S. a combined reservoir and filling member 2 and means for bold ing the parts together and to the spring.

Specification of Letters Patent.

, Patented Apr. 16), il ifl.

Serial No. 148,130.

Each of the lubricating members 1 consists of a substantially rectangular casing 3 formed of metal or the like and having one open face which is disposed toward the edges of the leaves L, and a pad l of compressible material such as felt or the like which will hold the oil and feed the same as it is required between the several leaves L. The upper and lower ends 5 and 6 ot' the casing 3 are somewhat wider than the sides 7. the former being wider than the thickness of the pad il: while the latter are less in width than the thickness of said pad thereby allowing the pad to be pressed tightly against the edges of the leaves of the springs. The upper and lower ends project over the top and bottom leaves L as shown in Fig. 3.

In order that the two lubricating members 1 may be securely held in place on the spring t), upper and lower ears 8 and 9 are formed on each of said members, said ears extending outwardly from the inner edges of the ends 5 and 6. The lower ears 9 are apertured to receive a clamping bolt 10, which together with the nut 11 thereon holds the lower portions of the lubricating members.

Each of the upper ears 8 forms one side of a chamber 12. the upper end 5 forming the bottom, while a. sheet metal piece soldered or otherwise secured in position forms the other parts. The walls of this chamber in effect form a hollow ar, and the inner and outer walls thereof are provided with alined openings to receive a bolt 13. the outer openings of the ears being substantially the same. diameter as the bolt. while the inner openings it are somewhat larger in diametn'.

Before placing the bolt 13 through the alining openings in each of the hollow ears, the combined tubular reservoir and filling member 2 is placed in position. said reservoir having its ends tapered as shown at 15 and disposed in the enlarged openings 14.-

ll hen the bolt extended through the. openings in the ears and through the reservoir and the nut 16 tightened. the upper end portions of the lubricating members will he forced toward each other, thereby pressing the pads 4: into engagement with the sides of the spring. When the bolts 10 and it} have been properly adjusted the device will be ready to have a. suitable lubricating fiuid inserted.

in the impeaportion of the res ervoir 52 substantially midway its ends forms a filling opening in which oil may be poured to be distributed to the pads l. It will be noted that the oil runs in both directions from the center of the reservoir and out the open ends thereof into the hollow ears or chambers 12, from whence it passes down through openings 18 in the ends 5 into pas sageways 19 which communicate with supplemental reservoirs 20. The latter reservoirs are formed by pressing the faces of the members 1 outwardly to provide depressions in which oil will collect to be distributed to the pads 4 which will feed it between the leaves of the spring when necessary. As a matter of convenience in stamping the casings 3, the reservoirs 20 are preferably circular in side elevation.

From the foregoing description taken in connection with the accompanying drawing it will be obvious that a very simply constructed lubricating device has been devised. The simple nature of the different parts of the device readily allow them to be formed of sheet metal or similar material and at a slight cost and furthermore, the several parts may be very easily and quickly assembled upon approximately any ordinary form of vehicle spring.

I claim as my invention:

1. A device of the class described comprising a pair of lubricators, a hollow ear on one end of each, a tubular reservoir coir necting said hollow ears and communicating with the interior thereof, and a bolt connecting the ears for holding the parts together.

2. A device of the class described comprising a pair of lubricators, a hollow ear on each, each of said ears having an opening in its inner face, a tubular reservoir having tapered ends disposed in said openings and communicating with the interior of said ears, and a bolt connecting the ears for holding the parts together.

3. A device of the class described comprising a pair of lubricators, a hollow ear on one end of each, each of saidears having alined openings in its inner and outer faces, a cylindrical tubular reservoir having its inner ends disposed in inner adjacent openings in its ears, and a bolt extending through said openings and the reservoir for holding the lubricators and the reservoir together.

el. A device of the class described comprising a pair of lubricators, a hollow ear on one end of each, a tubular reservoir connecting said ears and communicating with the interior thereof, a bolt connecting the ears for holding the lubricator and reservoir together, a supplemental reservoir in each of said lubricators formed by pressing the face of the same outwardly, and a passageway connecting each of said hollow ears with the adjacent supplemental reservoir.

A device of the class described comprising a pair of lubricators, each formed of a substantially rectangular casing, their upper and lower ends being wider than the sides, an ear formed on each end of each casing, a chamber connected with one ear of each casing, each of said chambers having alined openings formed in its inner and outer walls, a cylindrical tubular reservoir having tapered ends disposed in the openings in the inner walls of said chambers, a bolt extending through said alined openings and the reservoir, a second bolt connecting the other ears and a lubricating pad disposed in each of said casings, said pad being thicker than the width of the sides of the casing.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
