The springs 41, 41 are arranged below the pivot pin 2| and at .all times exert a force to move the handle upwardly to counter-balance the handle weight.

A hand operated mechanism is provided to operate the detent plate 31 and comprises two rods 6| and 62, the lower rod 5| having its extreme end 53 reduced and disposed in .an opening in a tab .54' of the detent plate 31, the shoulder 66 formed bythe reduction in the diameter of the rod 6| resting on the tab 54. The tab 54 is disposed at an angle with the latch member 31 to provide a substantial line contact with the shoulder 55. The upper end of the lower rod 6|,is reduced in diameter and extends loosely through an opening 51 in the plug 56 and into an enlarged recess 66l in the insulation of an electrical receptacle 66. Extending longitudinally through the handle |1 is the upper rod 52 having its lower end 6| extending through the insulation of the electrical receptacle 66 into. the enlarged recess 56 therein. The upper end 62 of the rod 52 is carried bya lever 63 pivotally mounted in the handle' and having a portion 64 for sliding engagement with iently grasp the handle and hand actuated lever 65 pivoted at 66 to the handie.' A spring 61 is arranged about the rod 62 and between a rigid stop 66 on the latter and a collar 66 slidably'mounted onthe rod 52 and which abuts against the lever arm 6|. The hand operated lever 65 is normally urged to the handle locking position shown in Figure 2 to provide a dead-man handle control, due to the force exerted by thespring 61, the latter also urging the Arod upwardly' in the handle out of engagement with thelower rod 5|-, The spring 61 acts-as a shock absorber and prevents damage to any of.4

the associated parts if the hand lever 66 is operated and the latch plate 31 for same reason its pivots. The lever 66 of the handle, whereby the operator can convene operate the hand lever 66.

The electric plug 66 is removably attached in.

the handle socket I6 by a clamp. secured to the socket bottom plate 46 which is welded to the handle socket VI6 and for1`ns a bottom wall of the socket, and to winch one end of the latch spring 45 is attached. -Suitable electrical conductors 1| extend from the contacts 12 in the plug receptacle through an elongated opening 13 in the bottom plate 46 to the unshown motor. The electrical receptacle 66 not only includes means defining an enlarged chamber 66 for effecting operative engagement of 'the two rods 6| and 62 but also is provided with contacts for con-v conductors 14 which extend.

nection to electrical upwardly in the handle to a switch 16.

In operation, assume the handle |1 to be in storage position, the locking detents 36, 36 are held in the recesses .46, 46 by the spring46. In order to lower the handle to a convenient operating angle the operator places his hand about the handle |1 and presses the hand lever 66 which `causes the rod 62 to move downwardly in the handle through the action of the spring 61, into ensasemexit with the upper end of the lower rod 6| causing the latter to move the latch plate 31 about its lpivot Vpins 36, :36. The'latch plate 31 moves against the force ofthe spring 46 and causes the detents 36,36 to move out of the respring 46 pivots insulation of an electric' the following claims. Protection is herein apanarco cesses 46, 46 to clear the stops 26,26 the handle |1 can then pivot downwardly into the operating range between the stops 26 and 26. The operator releases the hand lever 66 and the latch whereby the locking detents 36, 36 ride on the surfaces 4| of the segments 21, 21. At the same time the spring 61 moves the rod 62 upwardly in the handle |1 and upwardly in the electrical receptacle 66 out of engagement with the lower rod 6|, and' also moves the hand lever 66 to normal position, as shown in Figure 2. If the operator desires to use the handle in lowered position the hand lever 6.5 is. operated to pivot the latch plate 31 which moves the locking detents 36, 36 whereby the handle can be pivoted downwardly until the detents pass the stops 26, 26 and enter the working range between the stops 26 and 36 at which time the operator releases the `hand lever 66 and the detents 36, 36 will ride upon' the surfaces 42, 42 of the segments 21, 21 between the stops 26 and 36'. Should the operator desire to return the handle to the higher operating range or storage position he merely pivots the handle. upwardly and the detents 36, 36 willride over the cammed surfaces 66 and 6| on the segments'. 21, 21 by forcing the latch vplate 31 to move against the force of the spring 45, without the necessity of manipulating the hand lever 66.

From the foregoing it will be perceived that the motor housing 6 extends rearwardly to enclose the handle pivot 2|, that the locking detent the insulation of the electrical connector is provided with means to accommodate the two rods 6| and4 62 forming part of the hand operated handle control mechanism.

It is to be understood that the protection herein applied for is not confined to the particular combinations of features or elements set out in plied for, for any one or more of the features or elements referred to in the following claims, or
