Abstract
Abstract Particularly for working on automotive drive shafts including universal joints is a machine including a frame on which are mounted a headstock and a tailstock movable along a common axis toward and away from each other, the tailstock being lockable in any of several selected positions and carrying a tail centering device for supporting one end of a drive shaft. Also on the frame is a headstock having a head centering device mounted therein for rotation about the same axis and for movement along such axis toward and away from the tailstock. Also mounted on the frame is a hydraulic jack structure for moving the head centering device toward the tail centering device, the latter being particularly backed up by a stop for limiting axial movement of the tail centering device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
166 words
A machine for working on drive shafts comprising: a. a frame including a support bed; b. a tailstock slidably mounted on said support bed; c. means for retaining said tail stock in a selected position on said support bed; d. a tail centering device on said tailstock and having an axis; e. a headstock; f. means for mounting said headstock on said support bed; g. a head centering device rotatably and slidably mounted on said headstock coincident with said axis, said head centering device including an adapter socket having a bore of a predetermined diameter; h. an adapter including a yoke, a pair of bearings carried on the ends of said yoke to journal a universal joint cross therein; a central hub receivable in said socket, and means for removably retaining said hub in said socket; and, i. jack means on said frame for urging said head centering device to move slidably along said axis with respect to said headstock and toward said tail centering device.
Claim 2
Dependent Claim
166 words
A machine for working on drive shafts comprising: a. a frame including a support bed; b. a tailstock slidably mounted on said support bed; c. means for retaining said tail stock in a selected position on said support bed; d. a tail centering device on said tailstock and having an axis; e. a headstock; f. means for mounting said headstock on said support bed; g. a head centering device rotatably and slidably mounted on said headstock coincident with said axis, said head centering device including an adapter socket having a bore of a predetermined diameter; h. an adapter including a yoke, a pair of bearings carried on the ends of said yoke to journal a universal joint cross therein; a central hub receivable in said socket, and means for removably retaining said hub in said socket; and, i. jack means on said frame for urging said head centering device to move slidably along said axis with respect to said headstock and toward said tail centering device.
Claim 3
Dependent Claim
30 words
A machine as in claim 1 including means for removably receiving said tail centering device in said tailstock, and means for removably receiving said head centering device in said headstock.
Claim 4
Dependent Claim
77 words
A machine as in claim 1 in which said tail centering device is rotatably mounted on said tailstock; and in which said tail centering device includes a hub socket having a diameter substantially equal to said predetermined diameter of said adapter socket, and an adapter comprising a yoke, a pair of bearings on the ends of said yoke to journal a universal joint cross, and a central hub removably receivable in said hub socket for rotation therewith.
Claim 5
Dependent Claim
72 words
A machine as in claim 1 in which the universal joint cross is capable of fitting the bearings of a complementary universal joint yoke including a boss receivable in the drive shaft tube in an interference fit; and in which said jack means is capable of urging said boss into interference fit with said tube when said drive shaft is coaxially positioned between said head centering device and said tail centering device.
