  • One member, as the spindle, is locked in the work-receiving position of' the support and unlocked as it'travels to the operatmg position; trieireverse being true for the Second.
  • This device includes a piston carrying the last 'h'ed pi c'e and' operating in a cylinderunderthe' control-0i a valve, which may be actuated "by. a" track similar to that" governing the s m a i In the ccompanyingdrawings,

  • magma-e is shown as having a" shoulder l-" overhanging the end' of the passage.
  • the driver is held against downward displacement in the spindlepassage in its normal position by a key 44, fitting an opening in the spindle-wall and lying at its inner edge in a key-way 46 extending longitudinally of the lower portion of the driver.
  • the outer edge of the key lies in a slot 46 in the jackbody. In this slot, the key will move during depression of the spindle.
  • the spindle 34 is locked against depression by contact of transversely extended portions 50, "50 of its foot 38 with tracks 52, 52. These tracks are bridged together at 53 and are inclined downwardly and rearwardly at the same angle asgthe ways I8.
  • the bridge-piece is secured to thefront of the cap I6 for vertical adjustment by slot-and-screw connections 54.
  • the tracks may be brought into the proper relation to the foot of the spindle, for any adjustment of said foot which has been made to locate the upper end of the spindle.
  • a vertical cylinder 58 is formed in the jack-body 22 .
  • a tubular piston 60 having in an enlargement BI at its top a segmental depression 62, which receives the complemental under surface 64 of a bed-piece 66 for which the piston is a carrier.
  • the cylinder, with the piston may be considered as portions of the base.
  • the central portion of the segment 66 is shown as removed, the hollow thus produced being surrounded by an annulus which is Wedgeshaped in transverse section.
  • the plane upper surface 68 of the bed-piece is adapted to support the last L by contact with the crown-surface III of its cone.
  • the spindle 34 passes through a radial slot 72 in the bed-piece.
  • the piston and bed-piece are urged normally up by two expansion-springs I4, I4, surroundin rods I6, I6 depending from the piston-enlargement 6i through openings in the jack-base 20.
  • These springs are interposed between the piston-enlargement and the ba 4 and upward movement of the piston, produced by the springs, is limited by the contact of nuts 18 threaded upon the lower ends of the rods with the underside of the base.
  • the lower end of the piston carries a valve-seat 80, in an axial upward extension 82 of which the stem 84 of a valve 86 is movable.
  • the piston is locked against depression by a body of non-compressible liquid, such as oil, contained in the cylinder.
  • the valve In the workreceiving position of the jack (Fig. 1), the valve is held open by a bell-crank-lever 94 (Figs. 3 and 4), fulcrumed at 96 on the piston-enlargement 6
  • One arm 98 of the lever extends between the flange 90 and the enlargement 93, it being forked to receive the valve-stem.
  • the opposite arm I00 of the lever has a depending portion, movable in the travel of the jack along a track I02 parallel to the ways I8 and extending from a bracket I04 attached to the cap I6. With the jack in Workreceiving position, the track engages the arm I00 and actuates the lever to lower the valve from its seat.
  • the base 20 is forward in its ways l8 in the position of Fig. 1, fixed by the engagement of the projection 24 with the plate 26.
  • the foot 38 of the tubular spindle 34 rests upon the tracks 52, and the spindle is therefore locked against depression. drops a nail-head-down into the passage of the spindle, places over the spindle the passage :2: of
  • this support there are provided a member which supports the work to locate it accurately in preparation for the operation upon it, and a second member which measures the positioned Work and then furnishes the final pressure-receiving support, the first member functioning only as directing means without work-pressure. Further, the transfer of action between the two members is effected by simple and effective means, controlled automatically during the travel of the support in its customary reciprocation between the work-receiving and operating positions.
  • a support into cooperation with which work is moved and comprising two movable work-supporting members at least one of which is moved by the work, means for retaining one of the members against movement during movement of the other, and means for freeing the retained member and for retaining the other member against movement,
  • a support engaged by work and movable between two positions said support comprising two supporting members movable independently of each other by the engagement of the work, means for retaining one of the member against movement during movement of the other, and means acting during movement of the support for freeing the retained member and for retaining the other member against movement.
  • a support comprising a yieldable work-supporting member, means for locking the member in position to locate the supported work, a supporting member yieldable while the work is being thus located, and means for freeing the first member and locking the second member after the location of the work.
  • a jack comprising a base, a last-spindle and a last-bed-piece-carrier movable upon the base by the application of a last to the jack, means for locking the spindle against movement, and
  • a jack comprising a base, a work-engaging member movable upon the base, an hydraulic device by which the work-engaging member is positioned, a valve by which the hydraulic device is controlled, and means for operating the valve.
  • a jack comprising a movable base, a cylinder carried by the base, a piston movable in the cylinder, a last-bed-piece carried by the piston, a valve by which movement of the piston is controlled, means tending to close the valve, and means for holding the valve initially open and freeing it for closure in the movement of the base.
