HOISTING-DBUM.

To all whom it may concern.

Be it known that I, FREDERICK BAGLEY CLosE, a'citizen of the United States, residing at ,Los Angeles, in the-county of Los Angeles and State of California, have invented certain new and useful Improvements in Hoisting-Drums, of which the following is a specification; i

and its purpose is to make -a drum which shall be capable of being operated at varying speeds, without changing the speed of themotor, which-shall be much lighter than the ordinary hoisting a paratus'of the same power, and which sha be more powerful than such devices constructed in the ordi- In' the drawings Figure lshowsa plan view taken from above; Fig. 2, an elevation from the front; Fig. ,3, an "elevation from the right hand side; Fi 4, a planview. of the speed changin mec anism. Figsf'ti, 6, 7, and 8 are detaiFed views, illustrating V8.4 rious features. of the construction.

In the drawings, 10, is a-motor, which may be of any preferred style. In this case'I have employed an ordinary fourr cylinder gasolene engine, which is the motive power I at present prefer. The motor iscohnected with the speed changing mechanism, 18, by

a friction clutch, 11, which may be of any approved style, operated by a foot-lever, '12, connected with the clutch by suitable transmitting links and levers. The preferred construction :of the speed changing device is shown in Figs. 4, 5 6, and 7, which will be more fully explalned farther on; coupling, 17, connects the speed changing mechanism, 18, to a shaft, 19, =revolv1ng in bearings, 20. 'A pinion, 21, is keyed to the shaft and'meshes with a gear, 22, mounted on a shaft, 23, revolving in bearings 24. A pinion, 25, is mounted near the end of the shaft, 23, and meshes with a gear, 26. Mounted on the shaft, 27, with the gear, 26,

is a winding'drum, 28. "The drum, 28, is

controlled by two brakes, one a hand brake,

' 29, operated by a hand lever, 30, through a shaft, 31, and suitable intermediate connections.- A dog, 35, engaging'with a ratchet are, 36, and released by a hand-lever, 37, serves to hold the brake in position when set. The other, an air-brake, 85, operated by the lever, 82, piston, 81, and cylinder, 80, and supplied with air from the pump and Specification of Letters Patent. Application and March 19, 1909.

- reservoir, 78, through the sprocket, 38,

operates by means of-achain, 40," a similar sprocket, 39, V nut, 42, carrying a pointer, 43, travels along this screw in front of a gage, 44, and-by 'wound on the'drum. I My invention relates'to' hoisting drums,

The tate: is wte il"tof a 19, by a-icoupling, 17," as already; stated. Two'. gear wheels, 50 and 51, are. mounted on -the shaft, 47, seas to slide alon it, but are caused to',revolve with itby' key, 48. The gear wheel, 5.0, can bemoved along the ing in a. notch, 55, in the slide in a manner to bemore fully explained farther on. A similar slide, 56, provided with a notch, 57, and an arm, 58, serves to move the ear, 51, along the shaft, 47. An auxiliary s aft, 59, revolving in bearings at its extremities has secured to it three gears, 60, 61, and 62.- A second auxiliary,'or reversing shaft, 63, has two gears, 5. and 6, either mounted on, or integrally formed with, a sleeve which reverses on the shaft; The gear, 50, carries on its right hand face, a clutch, 66, adapted to engage with the clutch, 46,'on the pinion, 2. When the gear, 50, is forcedto its greatest distance to theright, the jaws, 66 and 46, will interlock and the shaft, 47, will be motor, thus giving the highestf-speed to the drum. The pinion, 2, W111 then drive the shaft, 59, as an idler. When thegear, 50,

gage with the gear, 61, on the shaft, 59, and

the shaft, 47, will then be driven by means its position indicates the amount of cable t (pref r; the construction I 5, .6,- and 7 ,which is as feather key,f 48, 'frevolves at one end the sleeve, 45 and atthe'fother in 'a bearin 49.

the slide, 53, operated by a lever, 54, engag-.

is carried over-toward the left, it will en-' ipe, 77. A- mounted on t e shaft, 23,

mounted on a screw, 41. A

shaft by means of the arm, 52, attached to driven directly with the full speed of the of the pinion, 2, and thegears, 60, 61, and 50, giving an intermediate speed of the drum. When the'gear,'-51, is moved over' toward the left, it engages with the gear, 62, on the shaft, 59, and the shaft, 47, will then be driven through the gears, 2, 60, 62,,and

51,'giving the slowest speed of the drum,-

while if the gear, 51, is moved over toward the right it engages with the gear, 6, on the reversing shaft, 63. The gear, 6, is'attached to, or formed integrally with, the gear, 5, which mesheswith the gear, 62,-. so that when the gear, 51, is engaged with the gear,

6, the shaft, 47, will be driven throughthe gears, 2,60, 62, 5, 6,- and 5l, the'introduction' of the intermediate gears, 5 and 6, serving to reverse the directionof motion and 'ving direct control to the lowering of the um so that the control will-not: depend on the brake alone,

As already stated, slides 53 and 56, which control the movements of the gears 50and 51, are operated by the'lever- 5 i. -'This,lever is mounted on a shaft, 67-, which revolyes inbearings, 68. A hand-lever, 69,11nk, 70, and

dog, 71, o crating on an arc,'72, serve to retain the ever, 54, in any desired osition'. .The shaft, 67 not only revolves in ebearfk ing's, 68,'but is capable of a short longitu ;T dinal motion therein, by means of which -by pushing the lever, 54, away from theoper-Q; ator as far. as possible, it will engage with. the notch, 57, while, by drawing it toward theoperator it will engage-with the notch, Y

55, thus giving control to all the movements. of raisin and lowering, by the one lever, '54.

It will a so be seen that by varying the ratios between the different gears, any-desired ration of speed variation canbe obtained, also that by changin the number of ears, more than three spee sof hoisting an one speed of lowering can be secured, if desired, and

I do not desire to limit myself to any special construction, arrangement, or combmation of gears, or auxiliary shafts, nor any number of speeds of raisin or lowerm as the device maybe change in all of, eso particulars without departing from my in.- vention.
