HQISTING APPARATUS.`

' SPECIFICATION for'mngfpart of` Letters Patent No. 624,810, dated May 9', 1899.

v Application tiled June 21,1898. Serial No. 684,070. (No model.)

v T a/Z whom, it ntay concern:

' tus, of which the following is a specification.

In this improvement I make use of two drums having gear-wheels and intermediate `pinions and a wheel supporting the shafts of such intermediate pinions and actuating mechanism for rotating such wheel 'and 'pinions and carrying the gear-Wheels and drums bodily around with the wheel and pinions to an application of actuate such drums simultaneously and at equal speed and friction devices fordetaining either of the drums, this portion of the apparatus being similar to that set forth in even date herewith, Serial No. 684,068.

In the present improvement I have added to the wheel that carries the intermediate pinions afriction or locking device by which such wheel can be arrested or its speed lessened, and I have added to one of the drums a separate driving mechanism by which an independent movement can be given to such drum and a friction device by which asecond driving mechanism can'be brought into action .3o

as necessaryi In addition to the foregoing I nd it advantageous to be able to apply a reversinggear and frictional driving device to the other drum andaclutch for connecting and disconnecting the pinion that rotates "the central wheel and its pinions. By these means both drums can be rotated in the same direction and at similar speeds, or when `the central wheeland pinions are held ina fixed position by the brake one drum can be rotated in one direction and the other drum will turn in the other direction, the-connection being between `the two drums bythe gears and the intermediate pinions, or one drum can be held stationary while the other drum is rotated by the second frictional power connection, so that one drum can be-in use independent of the other, and when the intermediate wheel is held the second `driving mechanism and frictional connection can be used to rotate one drum in one direction and the other drum the first drum in the opposite directionA through the intervention of the gears and pinions. This construction of hoisting apparatus is adapted to almost all the various circumstances under which hoisting drums and chainsL or ropes can be made use of, and in this apparatus the different motions that may be required either simultaneously or successively can be given to the dierent drums-that is to say, the two can be rotated .in the same direction, one can be held stationary while the other is being rotated in either one direction or the other, one drum can be rotated in one direction and the other drum rotated in the other direction, and an independent connection to the driving-shaft can be applied to one drum while another in dependent connection is acting upon the other drum, andeither one can be held or actuated without interfering with the movements of the other. v y

In the drawings, Figure lisa sectional plan view illustrating the present improvement. Fig. 2 is a partial elevation of the central drivin g-wheel and one of the intermediate pinions, and Fig. 3 shows straight gear connections in stead of bevel-gears. i

The shaft H is supported in suitable bearings, and it has around it the drums A and- B and also the WheelC, Aand there are gears d e at the respective ends ofthe drums A and B, which engage oneor more pinions D, having their shafts or axes rsupported inthe wheel C, and there are friction-straps or equivalentdevices L and M on the respective barrels A and B, and these frictiondevices are to be actuated by hand or in any suitable manner-f-4 such, for instance, as by levers L' M'.

In Figs. l and'2k the gears are represented as beveled, and in Fig. 3 the gears are shown as straight, the pinions D' D2 on the wheel C" IOD engaging the gears el' e. The operations corplied-such, for instance, as a brake-band 14 around the flange of the wheel C and a lever' 15, by which the band can be tightened or loosened.

The shaft K is to be driven by suitable power-such, for instance, as a double-acting engine with cranks at opposite ends, such engine being adapted to rotation in either one direction or the other.

At one end ofthe drum A is a gear-Wheel 18, with afriction-clutch 30 to engage the end of the drum A, and upon the drivin g-shaft K is a gear-wheel17,engaging the gear 1S,and a suitable device, such as the lever 20, acting upon the axial pin, and a cross-key is employed for bringing the friction 30 into engagement with the drum A. The drum B is similarly constructed for receiving the friction-clutch 25 upon the gear-wheel 24, and this is brought into action by any suitable device, such as the lever 35, axial pin, and cross-key, and upon the shaft K is a gear 22, and the intermediate `gear or pinion 23 causes the wheel 24 to always revolve in the opposite direction to thegearwheel 18.v Hence it will be apparent that it' both the gears 1S and 24 are in frictional engagement with the respective drums A and B, one Wheel rotating in one direction and the other in the other direction, they may be geared so as to run at the same or different speeds, as desired; but when lthis connection is made the intermediate pinions D, engaging the wheels d and e upon the respective drums, might interfere with the proper movements given to the respectivedrums it' the wheel C remained in gear with the driving-shaft K, and to prevent one force acting against another any suitable disconnecting device is advantageously provided for the pinion I upon the driving-shaft. K, which disconnecting device may be a sliding clutch 3l, actuated by a hand-lever, or any v.equivalent mechanism may be employed for this purpose.

I have represented the one driving-shaft K for all of the respective gear-wheels; but I do not limit myself in this particular, as the driving-shaft K may only actuate the gear-Wheels 17 and 22 and a separate pinion and motor may be applied to givemotion to the wheel C, as indicated by the dotted lines at 33, Fig. 3; but usually it is preferable to employ but one driving-shaft, as the coupling at 31 can be' made to disconnect the pinion I with facility from the driving-shaft K.

If the wheel C is revolved by the power, th pinions D, that are carried-around with the same, will act upon the lgears and rotate the drums A and B, the frictional devices for the same being slackened, and the drums can either wind up or pay out the ropes or chains, according to the direction of rotation, and if the strain upon the respective ropes is uniform the drums will rotate at the same speed, and if the strain is not uniform either the brake L or M may be made use of upon the drum wherev the strain: is least to clause uniformity in the action of the drums, or, if desired, either drum can be held stationary by the brake L or M, the other drum being rotated at an increased speed in consequence of the action of the gears D. i.

Thedrum A may be rotated by the' action of the gear-wheel 18 and the frictional device l30, the lever 20 being made use of in applying the frictional device in drivingsaid drum. During this time it' the clutch 31 is disconnected the wheel C will be loose and the drum B can be controlled by the lever M and brake as the rope or chain may pull oft same.

While the clutch 31 is disconnected and the wheel C loose the drum B can be revolved by the friction al device 25, controlled by the handle 35, andin this case the intermediate pinion 23 will cause the drum B to rotate in the opposite direction tothe drum A.

If desired, the brake 14 can be applied to the wheel C by the lever 15, the clutch 31 being disconnected, and in this position power can be applied to either the drum A or the drum B by the frictional connection 30 or 25, and if the power is applied to the drum A the drum B will rotate in the reverse direction, and if the power is applied by the frictional device 25 tothe drum B the frictional device 30 should be released and the drum A will be revolved in the opposite direction to the drum B by the pinions D. By this arrangement of gearing and frictiona-l connections either drum can be rotated by the connections to the driving-shaft K, or both drums can be driven by connections to the driving-shaft K, and the intermediate pinions, when the wheel C is loose, will have no' action in regulating IOO IIO

the speed of the drum, and the drums can v both be disconnected from the driving mechanism and controlled by their respective brakes, and the drums can be rotated by the pinions D, wheel C, and pinion Iwhen the latter is coupled to the driving-shaft, and the relative speeds of the drums can be controlled by the respective brakes, so that the action otA the respective drums and the direction of rotation are easily controlled by the attendant.

If the power is being applied by the Wheels A hoisting apparatus having 'the features herein described is available in raising or lowering or moving an article in almost any direction, according to the lead of the ropes andA the track and truck made use of in connection with such hoisting apparatus; but as these features of booms, elevated tracks, trucks, and sheaves or pulleys over which the respective ropes or chains pass from the drum are well known it is not necessary herein to elaborate the connection from the hoisting apparatus itself.
