flltomey Patented Nov. 29, 1932 UNETED STATES PATENT OFFICE EARL E. CRONENWETH AND CHARLES G. HAMER, OF SAN FERNANDO, CALIFORNIA SPRING OILER Application filed June 23,

This invention relates to an oiling device for springs of vehicles, and the present invention is an improvement over that forming the subject matter of a patent granted to us on May 5, 1931, No. 1,803,748.

The principal object of this invention is to make each device in two parts which are hingedly connected together so as to permit the parts to move with the movement of the spring and to provide means for making the device more efficient than the device shown in the before-mentioned patent.

This invention also consists in certain other features of construction and in the com- .bination and arrangement of the several parts, to be hereinafter fullv described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which Figure l is a side elevation of the spring suspension of an automobile showing the device thereon.

Fig. 2 is a longitudinal sectional view through the device.

Fig. 3 is a section on the line 38 of Fig. 2.

Fig. 4 is a section on the line- 44 of Fig. 2.

In these views, the device is shown generally at A and one of the devices is placed on each half of the spring B, and each device comprises an inverted channel-shaped part 1 and a lower channehshaped part 2 which telescopes into the part 1, the side edges of the part 1 flaring outwardly as shown at 3 so as to permit free movement of the parts.

Each of the parts 1 and 2 is formed of two sections which are hingedly connected to gether as shown at 4, the adjacent ends of the two sections being beveled as shown at 5 so as to permit free movement of the device with the spring.

The small end of the device is held on the small end of the spring by the clip 6 and the outer end of the bottom part of the section member 2 is curved downwardly as shown at 7 to fit over the bolt 8 of the clip as shown 1931. Serial No. 546,390.

in Fig. 2 to prevent movement of the device towards the axle C of the vehicle. This hookshaped part 7 can be formed separate from the bottom and suitably fastened thereto such as by rivets or the like.

A metal strip 9 is riveted to the bottom of the member 2 at the small end of the device and its ends turned over upon the pad 10 as shown at 11 in Figs. 2 and 4, so as to firmly hold the pad in the bottom of the device.

The two members 1 and 2 are resiliently held on the spring by the upper and lower cross bars 12 which project beyond the sides of the device and have notches 13 in their ends for receiving the hooks formed at the ends of the springs 14 as shown in Fig. 3. One of these spring assemblies is placed at the large end of the device and another spring assembly is placed at the hinged end of the smaller section as shown in Fig. 1.

I It will of course be understood that the device is formed with the oil reservoir 15 and the wicks 16 for leading the oil therein to the pad 10 as in the patented device and the device is also provided with the gaskets 17 at its ends as in the patented device.

From the foregoing, it will be seen that we have improved the patented device by providing means for holding the front end of the pad in position so that the pad is firmly held in the device, with improved means for yieldingly causing the two parts of the device to engage the spring so as to keep the oil saturated pad against the bottom of the spring, and by making the device in two sections hingedly connected together, the device has more movement than the patented device, and can therefore adjust itself to the movements of the spring.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

Having thus described our invention, what we claim as new is 1. A device of the class described comprising a casing formed of upper and lower channel-shaped members telescopically arranged, a pad in the lower member, a clip attached to the bottom of the lower member and engaging a part of the pad, spring means for pressing the two members towards each other, the bottom of the lower member having a hook-shaped part at one end, and a clip encircling the device and having a part thereof engaged by the hook for preventing longitudinal movement of the device.

2. A device of the class described comprising a casing formed of upper and lower chan- 5 nel-shaped members telescopically arranged, each member being formed of two sections hingedly connected together, a pad in the lower member, upper and lower cross bars engaging the top and bottom of the device,

' springs having their ends connected to the ends of the cross bars, said device tapering from one end to its other to conform to the shape of a spring, a clip encircling the small end of the device and the bottom of the lower member having a hook-shaped part for engaging a part of the clip.

3. A spring oiler of the class described comprising upper and lower channel-shaped members, the upper member being inverted and having its limbs fitting over the limbs of the lower member, each member being formed of channel shaped sections the bight portions of which are hingedly connected together, and the inner ends of the flanges of the channel-shaped sections being beveled with said beveled ends converging towards the hinge, a pad in one of the channel shaped members, and spring means for moving the members towards each other.

In testimony whereof we afix our signatures.

EARL E. CRONENWETH. CHARLES G. HAMER.
