NEW HAMPSHIRE, ASSIGNOB TO SULLIVAN IACHINEBY' COHPANY, A CORPORATION 0F MASSACHUSETTS HOIBTIN G IECHANISH application mea september 1o, 1931. semi 1ra. 532,114.

This invention relates to hoisting mechanisms, and more particularly to improvements in hoisting mechanisms of the double drum, ortable type.

improved hoisting mechanism. Another object is to provide an improved hoistlng mechanism of the double drum, portable ty having an imprved arrangement of t e 1l hoisting drums and the drivin meanstherefor whereby the hoisting mec anlsm 1s rendered extremelycompact. A further object is to provide an improved hoisting mechanlsm of the double kdrum type having improved l5 drive and control means for the drums.

These and other objects will, however, subsequently more fully appear.

In the accompanyin drawing there 1s shown, for purposes of i lustration, one form assume in practice.

In this drawing,- l

Fig. 1 is a central, longitudinally extending, vertical sectional view taken through the illustrative embodiment of the improved hoisting mechanism.

Fig. 2 is a transverse vertical sectional view taken on line 2 2 of Fig. 1. i

Fig. 3 is a transverse vertical sectional view taken on line 3-3 of Fig.`1.

Fig. 4 is a fragmentary side elevational view illustrating drum drive control means.

In this illustrative construction .there is showna hoisting mechanism of the double drum, portable type comprising a base 1,

herein in the form of a skid, having mounted thereon, a cylindrical housing 2. Closing one end of this housing is a circular plate member 3 supportin a motor 4. Attached to the opposite end o this cylindrical housing is a closure member 5, an intermediate plate 6, and an outer casing 7, the elements 5, 6 and 7 cooperating and form a gear housing for the drum drive gearing. In the present construction, the motor 4, which may be of any suitable form, has a c lindrical casing 8 detachably secured by bolts 9 to the closure member 3, as shown in Fig. 1; and the power shaft 10 of this motor is journaled in a bearing 11 supported Within a retaining member An o ject of this invention is to provide an a portion of the improved 12 positioned within the end he motor coupling sleeve 14,

s1on shaft 16. The shaft 16 is positioned ccntrally-within and rotatable low drive sleeve 17 and is closure plate 3.

power shaftl is splined at 13 to a which is invturn splined at 15 to a longitudinally extending transmisrelative to a holjournaled at one end in a bearing 18 positioned within the gear gear 20 fixed to a s casing 7. Fixed to the shaft 16 adjacent this bearing is a spur gear 19 meshing with a spur haft 21 arranged parallel with the shaft 16 and journaled within bearings 22 casing 21 is a spur gear 23 positioned within the plate 6 and gear Fixed to'and driven by the shaft meshing with an internal gear 24 keyed at 25 to one end of the drive sleeve 17.

adjacent its opposite ends 27, 28. Journaled on bear- This drive sleeve is journaled in bearings 26 supported within the hub .tions of the closur pore members 3 and 5, and

by the drive sleeve 17,

and driven by the gears 27 and 28, respectively, are winding drums being arranged within the housing 2 in sub- 30 and 31, these drums stantially end/abutting relation as shown.

Supported on a stub shaft 32 carried by the drum 30 and meshing with the gear 27 is a planetary gear 33 meshing l gear 34 formed on a rotatable reaction memwith an internal ber 35. The hub of the member35 is journaled on a bearing 36 supported by the hub of the adjacent end closure member 5. The

drum 31 is driven mission including planetary gear 37, internal through a similar transgear 38, and rotatable react-ion member 39.

The members 35 and 39 are externally grooved at 40 to form braking surfaces with which cooperate brake bands spectively. The adjacent ends of` the drums provided with braking sur# 30 and 31 are faces 43 with whic .44 and 45, respectively,

operating means.

the drive control brakes 41, 42 may assume va- 41 and 42, re-

h cooperate drum brakes each having suitable The operating lmeans for rious forms and are herein identical in structure, and each comprises an adjusting screw 46 cooperating with nut elements 47 carried within ear member of the brake bands.

s 48 attachedto ythe ends The adjusting screws 46 00 to effect drum are suitably journaled within the lower part of the housin 2 and have `fixed thereto at their cuter en s levers 49 and 50, respectivel Connecting these levers is a rod 51 suitab y pivotally connected at 52 to an operating handle 53. If desired, the controlling means for the brake bands 41, 42 may be provided with se arate operating handles so that the brake ands may be independently controlled. Wound on the drums 30, 31` are cables 54, and the cylindrical housing 2 is provided with lateral openings 55 to permit the cables to be extended from the drums outwardly laterally through the housing, as shown in 3.

The method of use of the improved hoisting mechanism will be clearly apparent from the description given. When the motor 4 is running, the drive sleeve 17 is driven at a reduced speed from the motor power shaft 10 through the transmission shaft 16, reduction gearing 19, 20, 23, 24. When the reaction member 35 frictionally is held against rotation by the brake band 41, and the brake band 42 is released, the drum 30 is driven from the drive sleeve 17 through the drive gear 27 and the planetary gear 33 meshing of the internal gear 34, the latter being held stationary at that time and the gear 33 rolling around this internal gear as a trackway drive. At this time, the drum 31 may freely rotate. When the brake'band 41 is released and the brake band 42 is aE- plied, the drum 31 is driven through t e gearing 28, 37, 38 While the drum 30 may freely rotate. Either drum when disconnected from its drive may be held a tion or frictionally braked by the 44, 45.

As a result of this invention, it will be noted that an improved hoisting mechanism is provided having improved drum driving control means. It will further be noted that due to ainst rotarake bands the improved arrangement of the dr'gus andV drum driving means, the hoisting mechanism is rendered exceedingly compact. It will further be evident that by the provision of the cylindrical housing the moving parts of the hoisting mechanism are protected, while at the same time these parts may be readily dismantled. These and other uses and advantages of the improved hoisting mechanism will be clearly apparent to those skilled in the art.

While inthis application there is specifically described one form which the invention may assume in practice, it will be understood that this form is shown for purposes of illustration only and that the invention 00 may be modified and embodied in various other forms without departing from its spirit or the scope of the appended claims.
