DOUBLE-DRUM Il-OIST.`
Application led September This invention relates to hoists, lout more particularly to hoists ci the double drum type in which either drum may loe driven from common driving shaft.
The objects of Vthe invention are to einploy fluid actuated means tor automatically connecting one or the other ofthe drums with a common source of power to he rotated in accordance with the direction ot rotation ot the power element, and to construct a rug ged, compact and etlicient hoist in which either or" the'drums and their associated elements may he readily assembled and disas`I semloled without disturbing the. assembly of the other druln. Y
Other objects will be in part obvious and in part pointed out hereinafter.
The invention consists of the combinations ot elements, features of construction and arrangement of parts having the general mode of operation substantially as hereinafter described and more particularly pointed out the appended claims and illustrated in the accompanying drawings, in which-Y Y Figure l is a longitudinalview in elevation and partly in section oi a double drum hoist constructed r'in accordance with the practice of the. invention, Y
Figure 2 is a view through Figure 1 talren on the line 2 2 looking in the direction of the arrows, and
Figure 3 is a top plan view talren through Figure 2 on' the line SP3-looking in the direction oi' the arrows, illustrating the main driver and opposed drum drivers.
Referring to the drawings, A indicates a hase plate. having an upwardly extending semi-circular trame l to which is bolted or otherwise secured a top 'trame C. The traine B and the toptrame C are provided with flanges D and E at their outer faces or ends. rlhe ilange l) provides a support for a side plate F which may he secured to said iiange by means ot holte. Likewise the lflange E forms a support for a side plat-e Gf. The side plate-.G` forms a. cover tor a portion ot one side of theV hoist and has formedV integrally therewith a gear casing H. The plates Fand Gin this instance also serve as a support for a hollow main shaft J en7n tending longitudinally of the hoist and supported near its ends with anti-friction bearings K. f 1
A haulage drum L and a tail rope drum O 16, 1925. Serial N0. 56,568.
are mounted loosely upon the main shaft J and carry on 'their inner faces opposed drum drivers P and Q respectively. The drum drivers P and Q. are in this instance formed integrally with the drums L and O and are preferably provided with oppositely entending' teeth adapted to interlock with corresponding teeth carried by a main driver R located between the drums L and O and mounted slidahly on the'niain shaft J. S cooperating` with the main driver R and the main shaft .l to prevent rotation ot the main driver with respect to said main shaft are preferably held stationary in the main shaft J and tit loosely in the main driver R.
Power i'or rotating the main shaftV is supplied loy'a motor T, in this instance secured or mounted on the endot the gear casingl-l helow the longitudinal axis ot the drums and having a side plate U. The motor .T may he of the fiat piston type, sometimes termed the Dalre motor, although any other suitahle type of reversible motor ot compact construction inay be used. A side cover plate V is provided tor the motor T and. has 'formed Keys 'i integrally therewith an exhaust chamber `W v to receive the exhaust from the motor and from whence the exhaust may pass to the atmosphere through a connection WC Pressure tiuid Jfor actuating the hoist may he supplied directly to a throttle valve X arranged rotatably in the cover plate V and which valve controls the admission oi pressure fluid to the motor together with the reversal of said motor. cured to the valve X provides a convenient means for manipulating said valve.
A crank shaft Z having a crank pin Z) whereby said shaft is'connected with the motor is provided with anti-friction hearings oV and. c arranged in the plates G andV U respectively and carries a pinion e lzeyed to said shaft which meshes with a gear 7" carried by a driving` shaft g. The driving shaft g entends longitudinally ont the hoist and preferably beneath the drums L and (l and is encased hy a suitable housing /liwhich is supported at one end hy the plate l? and at its other end by the gear casing H. An anti-friction hearing arranged in one end ot the housing ft supports one end ot the shaft g and the other end ot the shaft is provided with an antitriction hearing le supported by an end cover 0 which is secured to the plate F. ln addition to torin- A throttle lever Y seing a support for one end of the shaft 71., the cover also serves as a casing.
A pinion p keyed to the end of the shaft 7i which extends into the cover 0 meshes with a gear g keyed to the main shaft J. ln this instance the gear g is held against longitudinal movement on the shaft J by a. suitable nut r. il similar nut 1" is screwed on theopposite end ot' the main shaft l and with the other nut r prevents longitudinal movement of the shaft il and the elements mounted thereon. luy means of the train of gearing described, power from the motor will be transmitted to the main shaft l for rotating said shaft and the crank siaft Z is in this instance provided with a member .fi keyed thereto for countcrbalancing the inotor T.
Separate fluid actuated means are provided for moving the main -iver into engagement with one or the other of the opposed drivers carried by the drums. To this end a cylinder t is formed integrally with the cover plate V and is preferably located coaxially with the main shaft J. rEhe cylinder f has a cover plate u and is provided with a reciprccatory piston n. A' piston rod w, removably secur d to the piston u in any suitable manner, extends through one end of the main shaft J and is connected at one end with a cross head fr arranged slidaloly in the main shaft J and which supports an antiefriction bearing jz/ for the piston rod w. The piston rod w is preferably held to the bearing g/ by means of a screw e extending through said bearing and forming a trunnion for the inner member of said bearing. he end of the cross head a: is preferably screw threaded as at 2 to receive a correspondingly screw threaded collar or nut 3 for holding the bearing g/ Within the cross head az. The cross head x is provided with a transverse bore 4- to receive a bolt 5 which extends through slots 6 on opposite sides of the main shaft J and engages at its ends the main driver R. rThe bolt is preferably held against endwise movement by a nut 7 screwed on one end thereof. The slots 6 may be of any suitable length to permit sliding of the bolt 5 therein, but are preferably of a length to permit the head of the bolt 5 to pass over the inner faces of either drum in case it be desired to remove said bolt.
From the foregoing description is will be seen that the main driver R and the cross head a; are slidable longitudinally with re spec-t to the main shaft .l but are held against rotation with respect thereto.
The admission of pressure fluid to the cylinder t is in this instance also controlled by the throttle valve X. The throttle valve X'has a pair of ports 8 and 9 adapted to register with passages 1() and 11 respectively leading to the ends of the cylinder t. An exhaust port 12 is suitably located to provide communication between the atmosphere and a groove 1I?)V formed on the valve. The groove 13 is so formed on. the valve that when said valve is rotated from one limiting position to the other, said groove will register with one or the other of the passages and 11 and with the exhaust passage 12 for the purpose of exhausting pressure fluid from the cylinder ends. As before. stated, the valve X also controls the admission of pressure fluid to the motor, and the ports leading to the ino-- tor as well as the ports 8 and 9 are so arged with respect to each other that suie fluid is simultaneously supplied to the motor and to one or the other of the cylinder ends depending upon the direction of rotation of the valve X.
Braking means are provided for holding the drums against rotation after the main driver has been disconnected from the drum drivers. To this end a flange 14: is formed on adjacent faces of each drum to receive brake bands 15 which partly encircle the flanges 14. The bands 15 may be manipulated by any suitable means such as for instance a lever 16, but since such brakes are usually provided in hoists of this type and inasmuch as their functioning and operation are well known, further description thereof is considered unnecessary.
1n the operation ofthe hoist, assuming that it be desired to rotate the haulage drum L in a clockwise direction, the throttle valve X may be rotated to place the port 8 of thevalve in registration with the port 1 0 to admit pressure fluid into the front end of the cylinder t. In this way, the main driver R will be moved into engagement with the drum drivers P and thus hold the drum stationary with respect to the main shaft J and cause said drum to rotate therewith. IUpon reversal of the throttle valve X, pressure fluid from the front end of the cylinder twill pass through the port 10 and groove 13 to the atmosphere through the exhaust port 12. Continued rotation of the valve X in the described direction will place the port 9 in registration with the passage 11 for admitting pressure Huid to the rear end of the cylinder t for moving the main driver R into engagement with the drum driver Q carried by the drum 0. Reversal of the valve X will also cause reversal of the motor sorthat the drum O will rotate in a counter-clockwise. direction.
