Abstract: 7481. Justice, P. M., [Plant, T. G.]. March 29. Treeing.-A rumber of rotatable and expansible trees are mounted upon a turret, and the trees and turret are interlocked in a manner to be described. The trees are jacked and unjacked by a single lever, Each tree is rotated on its own axis by means of a hand-wheel 95, Fig. 2, and comprises a leg-front portion 126, a detachable back 160 hinged to the front portion 126. upon a spring bracket 163, and a foot-piece. The foot-piece comprises a member 130, mounted for longitudinal movement relative to the front portion, and an interchangeable sole plate 146 arranged on an interchangeable support 143, which is socketed in a support fixed to a foot-slide 127. The member 130 carries a bridge-piece 131, and is actuated by a jacking-slide 49, which carries a projection 140 extending through the foot slide. The member 130. in its initial movement towards the leg-front portion 126, carries with it, by reason of a latch 134, the foot-slide and the sole plate. As soon as the latch 134 is depressed by engagement with the leg-front portion, the foot-slide becomes dependent on the boot for its movement. Its rear end 154 then meets an adjustable spring stop 153, and the sole plate 146 and the member 130 of the foot-piece move apart to stretch the boot to an extent depending on the adjustment of the spring 156. At the same time, a projection 181, on the underside of the jacking-slide, actuates a heelslide 177, to which is linked, through a spring connexion, a bell-crank lever 170, the free end of which slides in a guide in the heel member 160, causing the latter to pivot about the bracket 163 to expand the heel. The tree is locked, when expanded, by a latch plate 97 at its rear end engaging a notch in the jacking-slide. An upper-stretching device 188 is carried by the foot-slide. The jacking-slide of each tree is actuated by one lever 46, Fig. 1, carried by the frame and having a notch 47 with which to engage a projection 48 on each jacking-slide. The jacking and unjacking lever 46 is controlled by a lever 52 connected to a treadle 58. When the lever 52 has been actuated to jack a tree, it is locked by a latch 63, 65. As each tree moves into its lower position, a projection 73 on the turret moves a lever 67 and removes the latch member 65, freeing the lever 52. This is then moved by the treadle spring, first releasing the jacking slide of the uppermost tree by actuating a lever 102 to lift the latching-plate 97, and then allowing a spring 111 to move the lever 46 to unjack the tree. The latch 63, 65 may be freed by a hand-lever 85. Each tree is locked against rotation on its own axis, when removed from the operative position, by means of a spring-controlled lever 116, Fig. 9, engaging a notch 114 in the hand-wheel 95. When a tree is rotated on its axis, the rear end 118 of this lever swings up into a notch in a projection 119 on the frame. Thus the turret is locked against rotation ; it is nut again free until the tree is returned to its initial position on its own axis. The means for turning the turret 4, Fig. 1, comprise a disk 7 with a notch 8, Fig. 10, for each tree and a pawl 9 actuated by a treadle 24, Fig. 1. This treadle cannot be operated unless the lever 46 is in jacking position. A slotted link 87, pivoted to the frame and controlled in position by the jack treadle 58, carries a projection 89, which locks the treadle 24 except when the treadle 58 is in its lowest position. The treadle 24 is coupled to a vertically reciprocating slide 16, Fig. 10, which carries the pawl 9. A bracket on the slide sustains a bell-crank lever 11, to one end of which the pawl is pivoted, the other end being held by a spring 20 to the slide 16. The cushioning of the pawl obtained by this arrangement avoids jar in moving the turret. To prevent the turret from carrying a tree beyond its operative position after the turret has been set in motion, it is held by a catch-lever 34 pivoted to a lever 36, which is cushioned by a spring 39 to prevent jar. Stops 33 corresponding to the trees co-act with this catch. The turret is freed by means of a pin 43 on the slide 16, which lifts the catch-lever just before the pawl 9 engages the notched disk 7. a
