Abstract: 1,017,621. Work benches. W. C. ALLEN. May 1, 1962 [May 5, 1961; Dec. 11, 1961], Nos. 16367/61 and 44253/61. Heading B4X. A work bench has a vertically movable worksupporting surface or deck constrained to move in a vertical path relative to the base member 1. The work-supporting surface 6 and base member 1 are pivotally connected at each end by a pair of struts 12 connected by a cross-bar 13. Each pair of struts is pivotally connected to the support surface 6 by a swivel joint 14 fixed in relation to the part 6, the joints 14 being equidistant from a vertical medial plane. Each pair of struts is pivoted at its lower end to an individual and laterally extending carriage comprising two members 19 terminating in wheels 18 that engage and run along the side members 2 of the base 1. To lower or raise the support surface 6 the carriages are moved towards or away from each other in such manner that they are always equidistant from and on opposite sides of the vertical medial plane. To this end each carriage carries at its centre a nut 20 which is mounted on a complementary screw-threaded shaft 22 journalled at its outer end in a bearing bush 23 in a housing secured to the end member 3 and journalled at its inner end in a ball-bearing race in a central crossmember 24. The two shafts 22 are threaded in opposite directions and their inner ends are locked together. The carriages 19 are guided by rods 25 rigidly attached to the end members 3 of the base. Each rod 25 carries a floating helical spring 28 that is compressed when the supporting surface 6 is lowered. The base is fitted with vertically extending telescoping units, each containing a compression spring 34, whereby the initial lifting motion of the surface is assisted. The screw-threaded shafts 22 terminate in hexagonal ends 35 adapted to receive a socket ratchet. By operating the socket ratchet in appropriate direction the work-supporting surface 6 may be raised or lowered. In a modification, Fig. 4 (not shown), the apparatus operates in an inverted condition such that the work-supporting surface is on the ground and the base uppermost. The worksupporting surface and the base are pivotally connected by a pair of struts. A pair of links each half the length of the struts are pivoted at their lower ends to the centre of each strut and at their upper ends to the base portion.
