To all whom it may concern:

Be it known that 1[, Gnnnnns Jenn Sonnnnnn, a citizen of the United States, residing at Council Blufis, in the county of Pottawattamie and State of Iowa, have mvented certain new and useful Improvements in Combined Hoists and Conveyers; and I do declare the following to be a full,

clear, and exact description of the inventionsuch as will enable others skilled in the art to which it appertains to make and use the same. i

My invention relates to improvements in combined hoisting and conveying devices,

and has for. its main object to provide an extremely simple device of this character which may be easily and inexpensively manufactured, and which may be advantageously used as either 'a conveyer or a hoist, or as both.

In carrying out this object, a pair of inclined sections are hingedly connected at their upper ends and equipped with rollers at their lower ends, and a hoisting device .is supported from the structure thus formed.

A further object of the invention becomes to provide novel means whereby the two sections may be swung outwardly, "thereby.

causing their upper ends to lower, and whereby these sections may be again moved toward each other to cause their upperends to rise, it being understood that the hoisting device has been properly attached to the goods to be raised.

With the above and minor objects in view, the invention resides in certain novel featurescof construction and combination herein described and claimed, and shown in the drawings wherein;

Figure 1 is a side elevation of a device constructed in accordance with my invention, showingthe position thereof when an equipped with rollers 3 at their lower ends.-

Each of the, sections 1 and 2 comprises a pair of parallel legs 4: which are connected at their bottoms by transverse bars 5, the

are hinge leaves 6 which are provided withinterengaging knuckles 7 on their upper ends, the reduced ends of a ridge bar 8 being passed through said knuckles and pro-- V-ided with nuts 9 as shown. By this construction, an inverted V-shaped frame is provided, the two halves of which are hingedly connected at their upper ends.

Depending from the center of the ridge bar 8 and preferably held thereon by a hook 10, is a sheave 11 over which a hoisting element 12 passes. This element is here shown in the form of a cable, but it will be understood that a chain or ordinary rope could well be employed. One end of the cable 12 depends centrally between the two sections 1 and 2 and carries a chain 13 on its lower end, the center of the chain being attached to the cable, while the ends of the chain are equipped with a pair of grappling hooks 14. The other end of the cable, however, depends between the legs 4: of the section 1 and is wound around a transverse shaft 15v which constitutes a Windlass having a crank 16 at one end, and a pawl and ratchet mechanism'l'Z whereby'it is held against movement in one direction until the pawl is released.

Secured at their lower ends to the transverse bar 5 of the section 1, is a pair of adjusting cables 18 which rise from their conmotions with said bar and pass over guide pulleys 19 and 20, which are carried re spectively by the upper ends of the legs of the frames 1 and 2 respectively, said cables then depending from the pu leys 20 and being wound around a second Windlass 21, which may be rotated by the crank 16 which is detachable, the Windlass 21 being also provided with a pawl and ratchet mechanism 22 for preventing its rotation in one direction.

With the parts constructed as above described, the chain 13 and the grappling hooks 14 normally stand adjacent the sheave 11, and the cables 20 are loosened by rotation of the Windlass 21 to allow the two frames 1 and 2 to move outwardly as seen in Fig. 1, whereby the ridge bar 8 is lowered, thereby allowing the hooks to beengaged with a barrel B or other device to be raised. The Windlass 21 is now rotated in the proper direction to wind the cables 18, thereby pulling the two sections 1 and 2 together to gradually raise the barrel B to the position seen in Fig. 2. The entire device may then be moved over the floor in the desired direction, since the rollers 3 are preferably swiveled to the sections 1 and 2.

When the barrel or other object being raised and transported, is conveyed to the proper place, the two sections 1 and 2 may be again allowed to move to the position seen in Fig. 1 to lower the load, or the cable 12 may be released by unwinding the windlass 15, thereby lowering the weight to the position seen in Fig. 3, without spreading the frame. The device may be used in the position seen in this last named figure, for hoisting and conveying in rather cramped quarters when it is impossible to spread the frame as above described.

From the foregoing description, taken in connection with the accompanying drawings it will be seen that a comparatively simple device has been provided for carrying out the objects of the invention, yet that the efiiciency thereof is not impaired by such simplicity.

Particular emphasis is laid upon the provision of the cables 18 and the Windlass 21, since by this means the inverted V-shaped frame may be gradually spread to lower its apex, or gradually contracted to raise the same.

One form of hoist has been described in connection with the device, but it will be understood that otherdevices may be eInployedto equal advantage.

I claim 1. A device of the character described comprising an inverted V-shaped frame having its two arms hingedly connected attheir upper ends and provided with supporting members on their lower ends capable of being moved upon a support, a Windlass on one arm of the frame, guides on both arms thereof, and a flexible element passing over said guides and wound around the Windlass on one arm of the frame, the other end of said element being secured to the other arm of said frame.

2. A device of the character described comprising a pair of inverted V-shaped frames, the two arms of each frame being hingedly connected at their upper ends, a transverse ridge bar extending from one hinge to the other hinge whereby to s ace the two V-shaped frames, transverse ars spacing the lower ends of said frames, a bearing carried by one arm of each frame, the two bearings being alined, a Windlass revolubly mounted in said bearings, guides near the upper ends of the two arms of each frame, and flexible elements secured at one end to said Windlass and at their other ends to the other arms of the frames, said elements passing over said guides, combined with a grappling device suspended from the rigid bar.

3. A device of the character described comprising a pair of sections each having a pair of legs, hinge leaves secured to the upper ends of said legs and having knuckles on their upper ends, the knuckles of one section interengaging those on the other section, a transverse ridge bar passing through the alined knuckles, a windless rev- 'olubly mounted on one of said sections,

guides carried by both of the sections near the upper ends thereof, and a flexible element secured to said Windlass and to the other section, said element passing over said guides, combined with a grappling device sus ended from the ridge bar.

11 testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
