The movement of the cam 24- may be accurately adjusted by means of a set-screw 28 in the free end of the arm 26, the inner end of which set-screw bears against the sliding cam-sleeve 27, above described. In the form shown drawiings I have-shown two sets of spur-gears 16, 1

in the closed drum diametrically opposite each other, so as to accurately balance the drum and to also distribute the wear between thesaid two sets of gears.

,The gears shown in the accompanying drawings are proportioned as follows: The gear 12, carried by the power-transmitting sleeve 2,

1s provided' with thirtyteeth The, gear 16, Th

with which it intermeshes, is provided with thirteen teeth. The spur-gear 14, keyedf to with eighteen teeth, and the spur-gear 17, with which it 'intermeshes,is provided with twenty-Ive teeth. The spurgear 13, keyed tothe hub of the open drum; is provided with twenty}- eight teeth, and the gear 18, with which it 1ntern1eshes,is provided with fifteen teeth. r f

.While the above is the proportion of the several gears, asshown in he accompanying drawings, it is to be understood that-by varying the relative sizes .of the gears toa limited degree the speed of the power-transmitting driving-shaft.

he operation ofthe mechanism is as foldrums are released bytheir brakes 19 and 2Q and the clutch is operated to lock the open drum to the driving-shaft, the power-transmitting sleeve 2 will be driven in the same'direction and'at the same speed as the driving-shaft, irrespective of the proportlgn'of the gears within the closed hollow drum." If the closed hollow dr by operating the brake 19 and and clutch'are released from the open drum,

16, 17, and

ed the gears16,

17, and 18 will be caused not only to rotate on their own axis but also to rotate bodily around the axis of the shaft, thusdriving the powertransmitting sleeve in the reverse direction to In the proportion the reverse 'speed'of the sleeve will be about one-eighth the forward speed of. the shaft. It will be seen that the structure as herein which the trains of gearing are balanced-to insure an even running of the power-transmitting sleeve, and one in which the said trains are-located entirely within the closed hollow drum, thus permitting a complete lubricationofthe gears without the necessity of carrying It will alsobeseen that theopen drum is operated upon both by the brake and bythe clutch, thus rendering the mechanism very compact, as well as simple Itwill,"iurthe'rmore, be seen enabled to utilize, spur-gears entirely, thus doing away T with the necessityof running-a spur gear' into an internal gear, which, it is Well known, re-' quiresa considerable amount more friction than that required between two spur-gears. is use of spur-gears; furthermore, mate rially simplifies the cost of the mechanism, as spur gears are cheaper to cut by a very greatmargin than internal gear;
