HORSE-POWER.

Specification of Letters Patent.

Application filed October 5, 1910. Serial No.. 585,420.

To all 207mm tt may concernl Be it known that l, Josemi K.. BOLAND, residing at New Orleans, in the parish ot' Orleans and State of Louisiana, have invented a new and `Improved Horse-Power,-

of which the followingr is a specification.

My invention relates to horse power mechanisms and it primarilydms for its object to provide an improved construction of machine of the type stated, in which the parts are designed for a quick and convenient adjustment to produce duplex motion, whereby light loads may be hoisted quickly and heavy loads slowly, and simple, easily operated and improved means is included. for instantly making;V the change from a quick to slow motion, and whereby the slack rope can turning' the drumv by hand power.

My invention consists in the peculiar construction and novel combination of parts, that constitute my improved horse power mechanism` all o which will hereinafter be fully explained. specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which Figure 1, is a perspectivel view, the shifting lever devices being` shown at .1 midway position to allow the hoistinglr drum to run idle and ready to slack. Fig. Q, is a longitudinal section of the same. the parts beingadjusted for slow speed. Fig. 3, is a partial longitudinal section, and shows the parts arranged for impartingl a high speed to the drum. Fig. 4;, is a transverse section on the line 4 4 on'Fig. Q, partsbeing omitted, and the lever in its midway position.

In the, practical arrangement, my horse powei, mechanism is mounted upon a pair of longitudinal base beams 11 made fast in any suitable manner, and the said mecha- .nism includes the t'ront and a rear yoke like standard Q-QO havingl bearing boxes on their inner sides to receive the .drum shaft 3, upon which the hoisting;- drum E is mounted and the rear end of the' shaft 3 is extended to receive a crank lever 4 for turningf the drum by hand when it runs loose, for taking up the slack rope. The frontjstandard 2 has a central tubular bearingftl for the driving shaft 5 the lower end. of which has a stepped bearing 50 in across beam 5l of the framing, and the upper/end carries the socket castingr for receiving the turning beam or pole 6 asis clearly shown'in Fig. 1.

in which a be readily taken up by.

.said gear is in mesh 'vertically from one end .and a bearing `above M and ll designate a xcdly held on the lower .end of the power shaft the upper one B of which is utilized when the parts are adjustedfor a fast. speed and the lower one M is used when the parts are set for a slow speed.

A is a beveled shaft and slidable thereon for beingl moved into or out/ot mesh with gear B, in a manner presently explained.

xear A. has a clutch face a for engaging a clutch hub on the large miter gear L loosely mounted on the drum shaft and normally held in mesh with the lower or slowy gear on the power transmitting shaft 5. It should be stated that the drum, its' shaft and the jear A turn together when the with the gear B and when so adjusted a fast speed is transmitted to the drum, and when the `rear Ais shifted out of mesh with aeanfBand beyond its midway or idle positioinit clutches with gear L and through said gear and gear M slow motion'is imparted to the bevel gear, the shaft and the drum.

7 designates -a bearing plate'that projects of the front` standard 2 and is disposed at rightangles thereto. Mounted in a hub bearing (l0 on the plate 7 Q3 on the back of the front is a'rock shaft N that is located and extends across .thedrum shaft as is best shown in Fig. which it will be seen the'shaft. carries a pair oi pendent crank members O-O, each of which -pivotally joins with a link l in parallelism with the drum shaft and whose free ends have stub pivots tl--S for titting' in the scatsll on the split ringl or yoke T that encircles the grooved neck 12 ot' .the bevel `gear A. To prevent the yoke T from turning with the gear A and jamming, I `ioin the two cranks O by a It should be here stated that the use of the strap Q or its equivalent is. essential since without joining; the two cranks O--O there is always danger of the said two cranks twisting out of alinemt-ilt and an irregular application .or shittingr ot' the yoke T. By using the member Q, a positive and uniform shifting of the yoke and with it the gear A is effected and lwith little orv no danger/of t-he yoke binding on the hub of the. gea# A. Shaft N at dits outer end carries a hird standard :'2

the upper 4-or fast pair of miter gears esA - el, by reference to semi-circular. strap Q. i

loc

preferably is, integral with the rocking lever fixedly held on the outer end of shaft N and which swings over a keeper head 62 on the bearing plate 7, formed with three apertures or sockets -Jy-slz and the lever carries a spring latch pin f that slips into either of the said sockets as the lever is shifted thereover.

I designates a springonger latch connected to the pin f for ulling the pin out of the sockets -g-a W en. it is desired to shift the lever.

vW designates a pusher `arm pivotally joined to the crank u and having a cam end fw' that rides through box wz and engages a dog @for holding it out of contact with the ratchet rim e2 on the drum, see Fig. 1.l

By reason of the peculiar construction and arrangement of the parts, shown and described,l it will be readily understood that when the lever F is at the midway position I shown in Fig. 1 `the gear A is out of mesh with gear B and as gear L now runs loose,`

the drum will be at the loose or idle position and can be'readily turned by hand to `take up the slack rope, When-high speed is desired, lever F is shifted over to the right to cause thel latch pin. to engage notch s which shifts gear A and holds it in mesh with the gear B andA in consequence fast speed is imparted to the drum. By shifting the lever F to the left to the limit, the gear Awill be moved out of gear with member B and will become clutched with slow gear L driven from 4the power gear M.

Heretofore'in horse power mechanisms of the general character shown, the pawl or dog that engages the ratchet on the drum is either thrown back by hand or by some special tripping device, when the drum runs loose. vIn my construction when the bevel gear is shifted to the midway position so the drum with the bevel Lgear runs loose, the

awl or dog isautomatically,v swung back and held out of-en'g'ag'ement with the ratchet (see Fig. 1) by the cam member fw that is coupled to the pendent end of the lever F, it beingobvious that sincethe lever is held locked to its midway position, the means for holding the pawl -free ofthe ratchet on the drum is also held locked to the said free position.
