Device for attaching a travel distance measuring instrument to a wheeled vehicle

Claim 2

In a device for attaching a travel distance measuring instrument to a wheeled vehicle, the combination comprising: a. a mounting bracket adapted to be rigidly fastened to said vehicle adjacent a wheel thereof; b. a bolt having a head portion and a stem portion rotatably mounted in said bracket; c. indexing means rotatably mounted on said bracket for engagement with said head portion of said bolt; d. spring means mounted on said bracket, which spring means is adapted to urge said indexing means to a predetermined position on said bracket; e. a split ball and socket with complementary means between the two meeting halves of said ball for locking them against rotation relative to each other and with registering grooves in the meeting halves of said ball, said ball being operable to clamp a portion of said instrument in said grooves between said meeting halves of the ball, movement of said ball enabling the placement of another portion of said instrument into, and out of, contact with said wheel of said vehicle; and f. means in said device to immobilize said ball on said bolt once said other portion of said instrument has been placed in the desired position comprising a nut screwed on the stem portion of said bolt and a complementary wing wrench engaging the outer walls of said nut, said spring means and said indexing means being adapted to maintain contact between said other portion of said instrument and said wheel.

Claim 3

In a device for attaching a travel distance measuring instrument to a wheeled vehicle, the combination comprising: a. a mounting bracket adapted to be rigidly fastened to said vehicle adjacent a wheel thereof; b. a bolt having a head portion and a stem portion rotatably mounted in said bracket; c. indexing means rotatably mounted on said bracket for engagement with the head portion of said bolt comprising a cam shaft insertingly mounted within a central hole for inserting said bolt therethrough and two separate circumferential grooves, polygonal in cross section, with spring means comprising several separate loops, lodged within said bracket, each finger of each loop bearing against one side of the polygonal grooves; d. spring means mounted on said bracket, which spring means is adapted to urge said indexing means to a predetermined position on said bracket; e. clamp means movably mounted on the stem portion of said pin, which clamp means is operable to clamp a portion of said instrument to said device, movement of said clamp means enabling the placement of another portion of said instrument into, and out of, contact with said wheel of said vehicle; and f. means in said device to immobilize said clamp means once said other portion of said device has been placed in a desired position, said spring means and said indexing means being adapted to maintain contact between said other portion of said instrument and said wheel.

Claim 4

In a device for attaching a travel distance measuring instrument to a wheeled vehicle, the combination comprising: a. a mounting bracket adapted to be rigidly fastened to said vehicle adjacent a wheel thereof; b. a bolt having a head portion and a stem portion rotatably mounted in said bracket; c. indexing means rotatably mounted on said bracket for engagement with the head portion of said bolt comprising a cam shaft insertingly mounted within a central hole for inserting said bolt therethrough and two separate circumferential grooves, polygonal in cross section, with spring means comprising several separate loops, lodged within said bracket, each finger of each loop bearing against one side of the polygonal grooves; d. spring means mounted on said bracket, which spring means is adapted to urge said indexing means to a predetermined position on said bracket; e. clamp means movably mounted on the stem portion of said pin, which clamp means is operable to clamp a portion of said instrument to said device, movement of said clamp means enabling the placement of another portion of said instrument into, and out of, contact with said wheel of said vehicle; and f. means in said device to immobilize said clamp means once said other portion of said device has been placed in a desired position, said spring means and said indexing means being adapted to maintain contact between said other portion of said instrument and said wheel.
