HAULAGE MECHANISM Filed April 8. 1922 Patented Dec. 24, 19 29 UNITED STATES PATENT OFFICE ROBERT C. OSGOOD, OF CLAREMONT, NEW HAMPSHIRE, ASSIGNOR TO SULLIVAN MACHINERY COMPANY, A CORPORATION OF MASSACHUSETTS HAUL-AGE MECHANISM Application filed April 8,

My invention relates to haulage mechanism. An object of my invention is to provide an improved hoisting or haulage mechanism.

Another object of my invention is to provide 5 an'improved mechanism of the type in which the motor is enclosed within the hoist drum.

A further object of my invention is to provide an improved haulage mechanism of the type in which the driving motor is enclosed in the 1 drum and the drum itself shall constitute one haulage means, while auxiliary haulage means is also provided. Other objects and advantages of my invention will hereinafter more fully appear.

In the accompanying drawing I have shown for purposes of illustration one form which my invention may assume in practice.

In this drawing,

The view is a central vertical section 6 through the illustrative embodiment of my improved mechanism.

In its illustrative form my improved mechanism is disclosed as comprising a rotating drum 1 journaled in a U-shaped support 2.

1' The drum comprises a central portion 3 and end portions 4 and 5, the latter being provided with stub shafts 6 and 7, of which the former is j ournaled in a standard or upstanding hanger 8 forming a part of the frame 2,

'30 while the latter is journaled within an annular member 9 which is in turn journaled in a standard or upstanding hanger 10 arranged at the opposite end of the frame 2. My improved haulage mechanism, as shown herein,

-35 is of the fluid pressure driven type; and enclosed within the central section 3 of the drum is an improved driving motor comprising a pair of rotors 12 and 13 journaled in the head 4 and in an intermediate head 14 46 which is arranged within the drum and spaced a short distance from the head 5. The rotors 12 and 13 are provided with intermeshing tooth blades 15 which cooperate to form pockets or chambers which expand in volume as 45 rotation of the rotors takes place, and suit- 1922. Serial No. 550,888.

chambers 18 and 19 at opposite ends of the rotors; and the expanded fluid will be freed from the interior of the drum in any suitable manner, as by ports in the head 4, not shown. The rotor 12 is provided with a shaft 20 extending through the intermediate head 14 and carrying a driving pinion 21 which drives a larger gear 22 fixed to a shaft 23 which is journaled in the heads 14 and 5 and which carries a smaller pinion 24 meshing with and driving a larger gear 25. The latter is fixed to a rotatable shaft 26 which extends through the head 5 and at its opposite end carries a pinion 27 which in turn meshes with a gear 28 journaled on a stud or stub shaft 29 fixed to the head 5 adjacent the periphery thereof. The gear 28 meshes with an internal gear 30 formed at the inside of a collar 31 which is supported upon a plate 32 secured to or, as shown herein, formed integral with the sleeve 9.

Suitable braking means comprising a braking surface 33 formed upon the collar 31, a brake band 34, and manual control means 35 therefor serves to hold the internal gear 30 against rotation and to cause rotation of the drum. At the opposite end of the drum from the brake band described is a flange 36 having a braking surface 37 formed thereon which is engageable by a brake band 38 having manual operating means 39. When the brake band 38 is applied and the brake band 34 released, the drum will be held stationary and the member 31 rotated as will be shortly made clear. Secured to the sleeve 9 outside of the hanger 10 is a winding member 40 over which a rope may be wound in such a manner as to permit it to be hauled in, the member 40 corresponding in its operation to a capstan disposed in a horizontal position. For convenience, in certain of the appended claims, the term capstan is, therefore, used.

From the foregoing description the mode of operation of this mechanism will be readily apparent. When the brake band 34 is applied, the member 31 will be held against rotation and accordingly the internal gear 30 will be stationary. Upon supply of fluid to the rotors 12 and 13, they will revolve, causing rotation of the train of gears 21, 22,

the brake band 34 under which circumstances the member 31 will rotate with the drum when the air is cut ofi, or at a greater speed if the air is still supplied to the motor. It it is desired to employ the winding member 40, the brake band 38 may be applied and the brake band 34 released, which will result in the rotation of the member 40; and by takin one or two turns about this member, a arge Weight can be easily handled.

If it be desired to use this apparatus for the operation of a jib crane, it may be readily employed with such a device by locating a sn-ubbing post adjacent the member 4C0 and passing the rope which is to shift the boom of the crane about the winding member 40. It will then be possible to raise or swing the boom as desired by applying the brake member 38 and releasing the brake band 33.

lWhen the boom has been moved to the :de-

sired position, the rope wound upon the member 40 may be either fastened over the snubbing post :by half hitches or may be released and either before or after movement-of the boom, as the case may be, application of the brake band 34 and release of the brake band 38 will effect raising of the load to be handled. The device may also be used to handle submarine drills, the main drum handling the drill itself while the smaller member 10 can be used to handle drill steels or vice versa.

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

What I claim as new and desire to secure by Letters Patent is:

i 1. A hoisting mechanism including a winding drum, a driving motor therefor enclosed therein, means for effecting rotation of said winding drum by said motor comprising a gear rotatably supported on an axis fixed with respect to the winding drum and parallel to but oifset from the axis of the latter, and a member comprising an internal gear surrounding said fi-rst mentioned gear and cooperating therewith, and means for supporting said member and internal gear for rotation upon an axis coaxial with the .axis of the winding drum, said member carrying a supplemental winding member beyond said supporting means.
