operatively connected toV the hoisting-drum 10, aroun whichthe cable is wound.

Twospools orcomplemental clutch mem-.-

bers 11 and 12 are mounted to'slide `oli-the shaft 7 andarefheld-to turn therewlthin any desired manner customary to devices of this character, and tothese spools actuating .erably overlap each other side by side, as shown., -The o rks'l of these `beams 15 and -15a are mounted toslide back and forth on collars 17, which-is supported between two on the bed-plate 1.

' preferably extendmg through the collars 17,

v1s a bearing-'stud 1 8, `18 is mounted -to .partlally rotate 4about itsv ,center, as shown. The diskV 18 is preferably u on which a cam-disk provided with vtwo 1 diametrically vopposite 4'spts 19 and 420, lwhich receive, respectively jt e o pplsitely-extending pins 19- V and 2,0a o the s g beams 15 'and 155' handle 22, which preferably extends upright, -as shown, and is fulcrumed in thebedplate. At a with `the cam-'disk vthe latter is provided with ha peri'heralcam 423, havinga flat dwell V 'surface and ada ted to en age with the laterally-extending ug24 of the brake'- beam 25.1. This beam is mounted to'rock b being fulcrumed v'at a point intermediate vo its ends', and to the outer end of thebrakeprovided atits upada ted to engage a brake' band or wheel 2 8,vedly heldA on the counter-shaft 7.

' It is to be particularly.A noted that the two slots 19 o theflower ends'of the rockingV which is To turn the cam-disk 18,'ithas1secured to one side,` preflerablyneariits edge, a link rod`21, in turn'conn'ected to an actuating leverfor point' .diametrically opposite .the point'of'connection of the link rod 21 Y IOO "beam a brake-rod 2,6 is connected, said rodand 20 are 'curved concentrically i with respect to the'disk throughout -a ortionof their length and are substantially stralght vor-otherwise shapedto constitute cams for the remainder'of their length.

In thepraetical operation of the apparatus when the actuating handle or lever 22 is in a true vertical position the peripheral cam 23 of the disk `18,is in engagement with the lug 24, so asto rock the brake-beam 25 and hold it in such a position that the brake-shoe 27 is in friotional engagement with the brake band orv 'Wheel 28. lf the handle 22 b e swung to: theleftfthe cam-disk 18 will be turnedpi'n a corresponding direction, and this motion of tlle'disk will be communicated, through -the cam portion of the slot 19 and the pin or stud 19, to the sliding beam 15, so as to rock the bar13and carry the spool 1 1 into clutching engagement with the clutch memberbf, thereby causing the counter-shaft 7 to turn in one direction. This motion of the cam-disk 18 is not communicated tothe other sliding beam 15a, because the pin 2Oa of said beam Will'then'work in the concentric portion of the slot 20. To reverse the motion, the same singleactuating handle or lever 22 is swung back again beyond the center and to the right, and this will manifestl cause the engagement of the spool 12 wit the other clutch member 6 to rotate the shaft 7 in the o posite direction through the instrumei'it-a ity ofthe beam 14, sliding beam 15a, and its stud 20a, working in the cam portion f the slot 20. Tt is also to be articularly noted that 'whenever the cam-d1sk 18 is moved to either the right or the left to drive the hoisting-drum 10 either in one direction or the reverse the positive driving engagement is preceded by a release of the brake. This is accomplished by the change in position ofthe peripheral cam 23, which slides oli' of the lug 24 and allows the drive-beam 25 to rockin the direction to Withdraw the brakeshoe 27. Conversely the cam-slots 19 and 20 are so arranged with res ect to the disk 18 and the levery 22 thereof t at in stopping the engine the engaged clutch is first thrown into an inoperative position before the brake is brought into play. Hence by this arrangement both in starting and stopping and reversing the engine there will be no undue strain upon the parts, and it is obvious that the hoists may be operated one inch or more at a time and lowered one inch or more at a time and that a load ma be stopped and held at any point of trave without interference of the arts. It will be seen that only one lever or iandle is used to operate both of the clutches and the brake mechanism in their redetermined succession, so as to control t e up-and-down motion and apply and release the brake Wherever necessary without the necessityof manipulating several actuating-'handles for this purpose.

From the foregoing description, in connection with the accompanying drawings, it will be seen that I-have provided a very simple and eflicient construction of hoisting-engine, which may be kept sensitively under control at all times and which is not raised by power and lowered by brake only, but has a ositive drive u on lowering by means o the herein-described brake ap liance.

As one handle `alone by the herein-described movements controls all the parts of the hoist in starting, stopping, and reversing the movement ofthe hoist, it is obvious that only one attendant is necessary for the engine, because a cable may be used, and they man on the first, second, or tenth story or any place between the highest point and the engine may havefull control of it.

While the invention as herein described and shown is embodied in a hoisting-engine, it is obvious that the invention is not limited thereto, but that the arrangement of the clutch parts and their single actuating camdisk with its single lever and 'brake mechanism is .applicable also to boats, automobiles, traction delivery-wagons or trucks and similar vehicles where it is a desideratum to reverse the movement oi' the vehicle or part to be driven without reversing the motion of the prime mover. This is especially of importance when the prime mover is an internal-combustion engine with the shaft always working in one direction.

Having thus described the invention, what is claimed as new is- 1. In a hoisting-engine, the combination of a hoisting-driim, a main drive-shaft, a`

counter-shaft operatively connected to the drum, two clutch members loose on the counter-shaft and geared with the main driveshaft so as to turn in opposite direction, clutch-spools mounted on the counter-shaft and adapted to engage with either one of the clutch members mounted on the countershaft, bars pivoted intermediate of`thei1 endsand connected to the clutch-spools at one end, beams connected to the lother ends of the said bars and each beam provided' with a stud, the said beams extending toward each other and provided with bifurcated ends, a supportfor the said ends upon which the beams are mounted to slide, a cam-disk centrally pivoted between the beams and provided with two diametrically opposite slots, each of which ha. a concentric portion and a cam portion, and the two concentric portions'and the cam portions lying opposite each other, the beams being provided with studs working in said slots, and means for turning said cam-disk in either one direction or the other, the arrangement of the concentric portions and the cam portions of the slots providing that when the disk is turned in either direction motion will be communicated to either one of the sliding beams.

2. The combination with a prime mover and its shaft, of a counter-shaft, a part to be driven operatively connected to the counter-shaft, oppositely-driving clutch mein- IOO IIO

bers on the counter-shaft and meshii with the shaft ofthe prime mover, a single utchdisk arranged to couple either one or the other of said clutch members with the counter-shaft, .a brake device 'for the countershaft, and meansv whereby the clutch-disk will operate the brake device. n

3. The combination with a prime mover and its shaft, of a counter-shaft, a part to be drive-n operatively connected to the countershaft, oppositely-driving clutch members and 4a counter-shaft meshing with the shaft ofthe prime mover', a single clutch-disk arranged to couple either one or the other of said clutch members with the counter-shaft, a brake mechanism arranged for" operatively engaging with the counter-shaft to brake the same, and means whereby the actuation of the cam-disk to couple either vof the clutch members with the counter-shaft will be-vpreceded by an` automatic actuation of the brake mechanism upon turning the 'camdisk.

4. The combination with a prime mover and its shaft, of a counter-shaft, a part to be driven operatively connected to the countershaft, opp ositelydriving clutch members and a counter-shaft meshing with the shaft of the prime mover. a single clutch-disk arranged to couple either one or the other of said clutch members with the counter-shaft, a brake mechanism for thecounter-shaft, and means whereby the turning of thecam-disk to couple either one 'or the other ofthe clutch members with the counter-shaft will be preceded by an actuation of the brake through clutchmembers to the counter-shaft, a peripheral cam 23 on said disk, a' brake-beam 25 arranged for engagement by said cam, a brake-rod 24 and'shoe 27 operatively connected to said beam, a .brake-band 28 mounted Yon the counter-shaft and designed for engagement with the brake-shoe, and a single ranged to be actuated by the said clutchdisk to couple either one or the other of said v operating-lever connectedto said disk, the

arrangement of the peripheral cam on the disk being such as to insure the positive actuation of the Vbra'ke-bemn and its brakevshoe subsequent to the uncoupling actuation of theclutch members by said disk and to also insure the release of the brake mechanism just preparatory to the coupling actuation of the clutch members by said disk. In testimony whereof1 I affix my signature in'presence of two witnesses.'
