sHocK-A-BsoRBING DEVICE.

To all whom it may concern:

Be it known that I, MAXIMILIAN K. GOLDEN, a citizen of the United States, residing .at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Shock-Absorbing Devices, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and 'use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in devices for checking the oscillation of vehicles, shown in the accompanying drawings and more fully set forth in the following specification and claims.

The object of'this invention is to produce a device simple in construction and operation and one which will admit of certain freedom of movement of the springs in either direction within prescribed limits, before checking the oscillation of the vehicle.

Other advantages and improvements will hereafter appear.

In the drawings accompanying this specification:-Figure 1 is a s1de elevation of the device showingit attached to the body ofa vehicle and its spring,fragmentary portions only of the latter being shown. Fig. 2 is a vertical section through the disk-shaped members of the device, with parts in eleva tion. Fig. 3 is a plan view of the same. Fig. 4. is a perspective view of one of the disk-shaped members. Fig. 5 isa perspective view of the other disk-shaped member,

- with parts broken away. 'Fig. 6 is a crosssectional view on line 6-6 of Fig. 3. 1

Referring now to the letters of reference placed upon the drawings :A indicates the body or frame of the vehicle; B its spring; and C its axle.

D indicates one of the disk-shaped members, its projecting arm (1 being pivoted to the clip 12 secured to the spring or axle of the vehicle. E is an opposing diskshaped member having a like projecting arm a pivoted to the clip a secured to the body of the vehicle. The disk-shaped member D is. formed with an annular flange D having an inner cam face D adapted to co-act with the cam E formed on the outer face of the concentric annular flange E .of the disk-shaped member E.

E is a nipple integral with the member E v Specification of Letters Patent.

through which projects a bolt F by means of which the members D and E are pivoted together.

F is a spring washer mounted on the bolt F to secure the nut F against accidental displacement and to hold the disks in close but elastic relation.

The flange D of the disk-shaped member D is partially divided from the body of said member by the kerf d, as shown in Figs. 3 and 5,the object being to provide for a frictional adjustment of the flange with relation to the concentric annular flange E of the opposing member E.

D are lugs projecting outwardly from the flange D. G is a set-screw engaging said lugs, by adjusting which the flange D may be compressed or expanded as required.

H is a. spring locking dog secured at one end to the flange D; its free end being adapted to enter grooves 9 formed in the head of the set-screw G to' secure the latter when adjusted.

Having thus indicated the parts by reference letters,.I will now explain the op eration of the device.

The device is installed by engaging the arm of one set of the opposing members to the body of the vehicle at the front and rear and on each side of the same, the arm of the other set of opposing members being connected withthe'axle or spring over which it is mountedl The set-screw G is then adjusted to givethe desired frictional tension between the-concentric flanges of the opposing members. As previously indicated,

the springs of the vehicle are free to act within certain limits, but upon the oscillation of the vehicle increasing due to traveling rapidly .over a rough road surface, the compression and rebounding action of the springs are put under check by the co-acting'cam faces D and E of the opposing members D and E encountering each other ;they being free to move within certain limits before engagingas shown in Fig. 2 of the drawings. I am thus enabled to check any sudden undue compression of the springs and the violent rebounding action following same.

Having thus described my invention, What I claim is l. A shock absorber comprising a pair of disks, each disk having a marginal flan e, the flange of one disk telescoping with t e flange of the other disk' and having direct peripheral engagement therewith, said disks being respectively connected with the body of a vehicle and its axle or spring, means for pivoting the disks together, means connected with the aforesaid means and engaging one of the disks to hold the disks yieldably together, the flange of one disk being slitted peripherally throughout a portion of its circumference to provide for frictional adjustment of said flange with relation to the flange of the other disk, and means for operating upon the slitted flange to expand or compress the latter and thereby regulate the frictional relation of, said flanges, said flanges having coactin said.

surfaces operative independently o yieldable holding means.

2. A shock absorber comprising a pair of disks arranged side by side and pivotally connected together and having marginal,

telescoping flanges, the outer flange having a pair of oppositely disposed cam surfaces and the inner flange having a pair of oppositely disposed cam surfaces for cooperation with the cam surfaces of the outer flange, said cam surfaces being confined between the disks and their flanges and operative parallel with the pivoted means of the disks, the disks being respectively connected with the body of a vehicle and its axle or spring, means engaging one of the disks to hold the disks yieldably together, the flange of one disk being slitted throughout a portion ofits circumference to facilitate frictional adjustment of said flange with relation to the flange'of the other disk, and means for expanding or compressing the slitted flange to regulate the frictional relation between the flanges, the cams-being operative independently of the yieldable holding means.

41A shock absorber comprising a pair of disks arranged side by side and provided with marginal telescoplng flanges, one of the disks having a central inwardly directed nipple, the other disk having a central opening, a bolt passed through the nipple and said opening, means on the bolt to yieldably secure the disks together with said nipple confined between the disks and flanges with the outer end of the nipple bearing normally against the inner face of the opposing disk, the inner surface of the outer flange having cams arranged between the disk and the free edge of the flange and the inner flange having cams for cooperation with the aforesaid cams and arranged bet-ween the corresponding disk and the free edge of the flange, the flanges being parallel with said nipple, said cams coacting independently of said yieldable holding means and the disks being respectively connected with the body of a vehicle and its axle or spring.

In testimony whereof, I sign this specification in the presence of two witnesses.
