At the opposite ends the plates are held zo To these ends my invention consists genapart by the bolts 19, havingthe enlarged cen- 7o erallyin a hoisting device of the construction ter parts between the two plates and the hereinafterdescribed,and particularly pointthreaded outer end to receive the clips or ed out in the claims. yokes 20 and the fastening-nuts 21. These The invention will be more readily underbolts are made hollowv in order that a short stood by reference to the accompanying drawpiece or bar of iron may be inserted through 75 ings, in whichthem and by which the person using the de- Figure l is a vertical elevation of a hoistvice may hold it steady while he turns the ing device embodying my invention.

Fig. 3 is a side view showing the range the take-up or pressure rolls or pulleys So worm-gears Fig. 4 is a partial sectional 23, springs 24 being provided in connection view thereof on the line y y of Fig. 3. Fig. with one of the same in order to force the 5 is a detail sectional view of the worm-gear rolls toward one another and grip the rope employed. Fig. 6 is a sectional view of one between them. The shaft of one of the rolls of the hollow bolts used at the upper end of extends through one side of the plate, and this 8 5 the device. Figs. 7 and 8 are detail views of shaft and the shaft of the winding-wheel 4 the reversible ratchet which I prefer to emare provided with small pulleys 25 to receive ploy for turning the worm. a belt 26, whereby the pressure rolls are As shown in the drawings, 2 and 3 repredriven at the same or slightly-increased speed 4o sent the side plates, between which the windas the winding-wheel 4, thereby drawing the 9o ing- wheels 4 and 5 are arranged. These rope steadily away from the wheel or pulley wheels are preferably grooved, as shown, and 4 and holding the rope tightly about the same, have the slanting sides to compel the rope to so that the full grip of the rope upon both seek the center part of the pulleys or wheels, pulleys is secured.
andthe pulleysare secured firmlyupon shafts The ratchet device comprises the handle 95 which extend through the sides of the plates 16, the end of which is the sleeve 27, having a 2 and 3, and each provided with a worm gearsquare hole to admit the end of the shaft 13, wheel 6 and 7. Furthermore, the outer ends and this sleeve is provided with a ratchet to 8 of these shafts are preferably tied together be engaged by a spring-pawl 28 on the handle 5o by a strap 9 to prevent their spreading. part. By simply reversing the position `of roo the ratchet upon the shaft the ratchet may be made to operate in an opposite direction. This reversed movement is necessary, as the device is often used for lowering heavy articles as well as for raising the same.
In use the device is secured to a xed post or other object by ropes extending from the yokes or clips 20. Then the lifting cable or rope is threaded through and around the win ding-wheels and then carried through the pressure-rolls and drawn taut, after which the device is ready for immediate use. The grip of the rope upon the two winding-wheels, and particularly the crossed relation of the parts of the rope upon the winding Wheels or pulleys which insures the tight grip of the rope thereon, enables the transmission of a very heavy power from a simple crank or lever. Further, it is obvious that the worm will lock the gear-wheels, and thus the winding-wheels, in any position, it being necessary to turn the Worm in order to draw the rope in or allow it to be drawn out of the device.
Further advantages of my device lie in its compactness, its strength, and its durability.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the side plates, of the winding-wheels provided between them, the shafts of said wheels extending through said plates, the worm gear-wheels provided upon said shafts opposite one another, a transverse shaft carryingaworm to mesh with both said gear-wheels, bearings upon t-he said plate for said transverse shaft, the pressure-rolls provided between said plates, means for dri vin g said rolls from one of said winding-wheels, and means for securing the whole device in place, substantially as described.
2. The combination, with the side plates, of the winding-wheels provided between them, the shafts of said wheels extending through said plates, the worm gear-wheels provided upon said shafts opposite one another, the transverse shaft'carrying a worm to mesh with both said gear-wheels, bearings upon the side plate for said transverse shaft, the pressurerolls provided between said plates, means for driving said rolls from one of said windingwheels, and one or more loops or yokes provided on the upper end of said plates and whereby the device may be fastened as desired, substantially as described.
3. The combination, with the side plates, of the winding-wheels provided between them, the shafts of said wheels extending through said plates, the worm gear-wheels provided upon said shafts opposite one another, the transverse shaft carrying a worm to mesh with both said gear-wheels, bearings upon the side pla-te for said transverse shaft, the pressurerolls provided between said plates, means for driving said rolls from one of said windingwheels, and one or more loops or yokes provided on the upper end of said plates and whereby the device may be fastened as desired, and the upper ends of said plates being provided with an openin g or openings through which a bar may be inserted to hold the device securely while said worm-shaft is being turned, substantially as described.
4. The combination, with the side plates, of the winding-Wheels `provided between them, the shafts of said wheels extending through said plates and provided with worm gearwheels, a Transverse worm-shaft extending between said worm-wheels and carrying a worm to mesh therewith, a ratchet device for operating said transverse shaft, and take-up means provided between said plates, substantially as described.
5. In a device of the class described, the combination with the sideplates, of the winding-wheels arranged between them, the parallel shafts of said wheels, the worm gearwheels upon said shafts, the transverse shaft carried by one of said plates and provided with a worm meshing with both of said gear-wheels, means for revolving said worm to turn said winding-wheels in opposite directions, whereby the free end of a'rope passed around said winding-wheels may be advanced through the device as said wheels are turned, and means for taking up the slack in the free end of the rope, substantially as described.
In testimony whereof I have hereunto set my hand this 27th day of February, A. D.' 1895.
