Abstract
Abstract An extension to be engaged with one end of an elongate cylinder and piston type shock absorber to facilitate engaging said shock absorber with and between its normally related relatively shiftable structures upon increasing the normal spacing apart of said structures; said extension being such that it remains in axial alignment with the shock absorber, requires no modification of the shock absorber to effect its connection therewith and connects with standard shock absorber mounting means without alteration or modification thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
233 words
In combination, vertically spaced relatively vertically shiftable upper and lower structures; a cylinder and piston type shock absorber having an elongate substantially vertically extending top assembly, mounting means securing the upper end of the top assembly to the upper structure, an elongate substantially vertically extending base assembly including an elongate cylindrical body telescopically engaged with the top assembly and having a crowned lower end and an annular mounting ring fixed to the center of the lower end with its central axis normal to the central axis of the body and adapted to normally receive a horizontal mounting pin on the lower structure, an extension for and extending axially downwardly from the lower end of the shock absorber and including a pair of elongate vertical plates with laterally spaced upper and lower portions, the upper portions occurring adjacent the opposite ends of the ring and having orienting means engaging said ring to maintain the plates in predetermined position relative thereto, the lower portions having axially aligned openings spaced below the ring and receiving the mounting pin, fastening means releasably securing the plates together and in clamped engagement with the ring and stop means maintaining the shock absorber and the extension in longitudinal alignment and including means at the upper ends of the plates engaging opposite sides of the body at points spaced above and on a plane radial to the axis of the ring.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
27 words
A structure as set forth in claim 1 wherein said orienting means includes circular inwardly extending projections on the plates engaged in the ends of the ring.
Claim 4
Dependent Claim
56 words
A structure as set forth in claim 1 wherein said orienting means includes circular inwardly extending projections on the plates engaged in the ends of the ring, and semi-circular, radially inwardly disposed shoulders spaced radially from and about a portion of each projection and engaged about the exterior of the ends of the ring related thereto.
Claim 5
Dependent Claim
42 words
A structure as set fortH in claim 1 wherein the stop means includes inwardly turned ears on the plates above and at opposite sides of the orienting means and the ring and having upper edges engaging the lower end of the body.
Claim 6
Dependent Claim
43 words
A structure as set forth in claim 1 wherein the stop means includes upwardly and laterally inwardly opening recesses in the upper portions of the plates above said orienting means and engaged with and about the lower portion of the body adjacent thereto.
Claim 7

67 words
A structure as set forth in claim 1 wherein the stop means includes a flange on each plate on a plane parallel with the axis of the orienting means and ring and projecting above the orienting means and ring to occur in spaced relationship from a related side of the body and a stop screw carried by the flange and engaging said related side of the body.
Claim 8
Dependent Claim
40 words
A structure as set forth in claim 1 wherein said fastening means includes aligned fastener openings in the plates in axial alignment with the orienting means and the ring and screw fastening means engaged in and through said fastener openings.
Claim 9
Dependent Claim
61 words
A structure as set forth in claim 1 wherein said orienting means includes circular inwardly extending projections on the plates engaged in the ends of the ring and said stop means includes inwardly turned ears on the plates above and at opposite sides of the orienting means and the ring and having upper edges engaging the lower end of the body.
Claim 10
Dependent Claim
93 words
A structure as set forth in claim 1 wherein said orienting means includes circular inwardly extending projections on the plates engaged in the ends of the ring and said stop means includes inwardly turned ears on the plates above and at opposite sides of the orienting means and the ring and having upper edges engaging the lower end of the body and said fastening means includes aligned fastener openings in the plates in axial alignment with the orienting means and the ring and screw fastening means engaged in and through said fastener openings.
Claim 11
Dependent Claim
71 words
A structure as set forth in claim 1 including an elongate rubber grommet about the pin and engaged in and through the openings in the lower portions of the plates, said pin having a flat axially disposed surface at one end opposing one end of the grommet, a backup washer on the pin adjacent the other end of the grommet and a nut engaged on the pin and against the washer.
