YIn Figs. 5 and G are shown more in detail the construction of the well known trolley drum and means for controlling the same inserted for the better understanding of my invention as hereafter set forth.

Considering Figs. 5 and 6, 19 is the crank disk connecting with the connecting rod 27 of the trolley engine, i1 is the shaft on which the drum proper l0 slides and turns, 42 is the friction .member which is keyed to the shaft, and 43 the conical friction surface on the end ofthe drum which acts against a corresponding surface on the frictionmember '15 is a, screw member engaging a screw threaded recess in the shaft bearing 46, the screw member impinging against thelend of the trolley drum and being turned by the lever 21 shown in Fig. l. The band friction le surrounds one end of the drum and this is controlled by the lever 23 (shown in Fig. l) pivoted to a standard 23". It will be readily understood that the lever 23 causes the friction band Llto act to check the rot-ation of the trolley drum and the lever 2l operates to turn the screw 45 and to press the same against the end of the drum, forcing the latter against the friction member and causing the drum to turn. Thus when the drum is to be used for pulling out the trolley to the endof the boom, the friction band is released and the lever 21 oper ated to turn the screw and throw in the drum friction, thus causing the drum to wind up the trolley rope. Then the trolley is to run in, the drum friction and theband friction are both released and the rlatter is used to check the movement of the drum when the trolley reaches the right point. Each of the main hoisting drums is provided with a friction clutch similar to that shown at 43 and 44 for the trolley drum and is operated by a suitable lever similar to lever 21, neither of the above parts being shown, these levers being connected to the reach rods 17 and 18 in the usual manner.

The parts so far designated are old and well known in hoisting devices and with the above explanation need no further description to understand the application of my invention, the novel features of which will now be described. The operating levers A and A which are connected to the connecting rods 17 and 18, respectively, are horizontally disposed atthe operators position side by side with an intermediate space between and compounded so that a man can stand be tween them and by pressing down with each hand easily control the two drums. Combined with these are one or more members or devices controlling the traverse of the trolley, herein through the agency of compressed air, such Vmembers or devices being so connected to the friction controlling hand levers A, A that the operator with the same hand with which he operates the mechanically connected friction levers can operate a traversing control device, so that the cooperating movements of the bucket and its traversing support may be simultaneously controlled by the same operator. Such traverse control members may be of any suitable form and construction, but herein they are preferably embodied in the form of grasping devices, one on each friction lever, and movable independently of the latter. In the specific form of the invention herein shown, one grasping device is` employed to control the friction clutch for thetrolley drum, and the other the trolley drum brake. As here shown, the friction band lever 21 of the trolley drum is connected to the piston rod 25 of the air cylinder 20 while the drum friction clutch lever 23 is connected to the piston rod 24 of the air cylinder 22. Each of these air cylinders 20 and 22 is connected to a compressed air tank 38 or other source of compressed air through the pipe d, which first passes from the tank through the controlling valves B and B located as here shown in the horizontal operating levers A and A' and thence to the cylinders through the sup ply pipes 3l and 35. Thus it will be seen that each friction of the trolley drum is controlled by an air valve located in one of the horizontal levers by which the main drum frictions are controlled and these air valves are operated as here shown by means located on the handles of said horizontal lever as hereinafter shown.

ln Figs. Q, 3 and l are shown the details of the horizontal levers with their connecting parts. As here shown, the levers A and A' are journaled bymeans of trunnions in suitable standards and just far enough apart so that a man can stand between the handles and bring each within easy reach of his hands and so that each lever may be worked by bearmg down with one hand or the other. rlhe two levers are shown in Fig. 3 and similar parts in each lever are similarly lettered. At the point where the trunnions are located, there is an enlargement B which is hollow and forms an elongated valve chamber,` openings being. formed lthrough each trunnion connecting with the inside l of the valve chamber. A cover or plate b closes the top of the valve chamber B. At the rear (right hand as viewed in Fig. 2) end ofthe lever there is an extension to which is pivoted the vertical connecting rod (l, the lower end of which connects with the lever C journaled to a suitable standard and having its end at a considerable dis tance horizontally away from the stan-lard so that an upward pull-on the lever' C will "f'lrotate the lever in its bearing.

A A n Connected with thelever C` 'near its ulcruni is the connecting rod 17 already described which operates .the main drum friction.v 'Thus 'the l leverage of the lever A. 1s compounded and an increased pull exerted onthe rod 17 and 1 the lever A is thus operated with-the rela- -tively little force or weight-applied to it.

Air passes out of thechamber kto *the service pipe 35 on one side and 34 onthe opposite side through a porti?)2 formed v in the bottom ofl the vvalve charnber near its rear end and connecting through a passage- ,way formed 'infthe body of the casing with *forward of the port b2. -A slide valve is .provided for-'opening the port b2 and connecting ther valvecharnberwith the service pipe-and for closing it and exhausting the contents of theservice pipe. The valve'has g the chamber adjacent'to the port Y. 52 'and4 adapted to 'cover and uncover it, and-a like flange b9' on'the opposite side vof the portbf,

` uthese vtwo flanges being connectedby a horizontal web b which forms 'beneath a passage for the discharge of air fromthe port b2 tothe port 723 when the valve-'is in its' rear position. Uprightilanges b? tit loosely infthe'valve chamber and form" guides, by
