6 Claims.

The invention relatesto a beekeepers hoist. An object of the present invention is to provide a simple, practical and eflicient beekeepers hoist of strong, durable and comparatively inexpensive construction adapted to eliminate from the apiary heavy lifting and capable of enabling all typesof beehives to be readily employed and conveniently operated.

Another object of the invention is to provide a beekeepers hoist ofthis character equipped with an adjustable hive engaging clamp adapted to be readily applied either to the hive body or to any one of the supers and capable without liability of slipping of enabling the hive body or one or more supers to be lifted for various purposes, such as an examination of the hive body, removal of the supers or lifting all of the supers from the hive body to enable anew or empty super to be placedpin position on the hive body.

A furtherobjectof the invention is to provide a beekeepers hoist comprising hoisting mechanism, a, free swinging sling carrying a hive clamp,

and a supporting frame having legs and adapted.

to be arranged over a hivewith said legs spaced from the same so that when the supers are lifted from the hive body they may be swung from a position above the hive body laterally to a. position beyond the hive body and be suitably secured to one of the legs for holding them out of the Way topermit the hive body to be conveniently inspected. i

Another object of the invention is to provide a beekeepers hoist comprising a supporting frame,

block and tackle mounted on the frame and a hive clamp having means forengaging a hive body and for also engaging a super for lifting one or more supers and a sling carried by the block and tackle and having flexible sling members connected to the clamp and arranged to engage the hive body at the top thereof and cooperating with the clamp forholding the supers intact particularly when they are swung away from the hive body. 4 l

It islalso an object of the inventionto enable the hive body and the supers to be readily weighed when desired.

A further object of the invention is to provide a beekeepershoist capable of being compactly folded to enable it to be easily carried from one apiary to another by automobile or other conveyance.

With these and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawing andpointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any advantages of the invention.

In the drawing:

Figure l is a perspective view of a beekeepers hoist constructed in accordance with this invention andshown applied to a hive.

Figure 2 is an elevation of a portion of the hoist taken at right angles to Figure 1.

Figure 3 is a detail perspective view of one form of the hive engaging clamp. 3

Figure 4 is a detail perspective view of the cap of the sling.

Figure 5 is a detail view illustrating the ar;- rangement of a scale between the block'and tackle and the sling of the hive engaging clamp.

Figure 6 is a detailview illustrating a modification of the members for connecting the sling with thehive engaging bars of the clamp.

Figure '7. is a detail view of a triangular loop or ring for connecting the sling members together and for connecting the sling with the block and tackle.

Inthe accompanying drawing in which is illustrated the preferred embodiment of the invention, the beekeepers hoist includes a tripod frame I composed of

legs

2, 3 and 4 connected together at the top byirons 5 and 6. The legs of the tripod frame which, as is true of all parts of the hoist, may be constructed of any suitable material of any desired dimensions and said

legs

2, 3 and 4 preferably consist of light bars of wood. The leg 4 is composed of spaced parallel bars spaced apart by spacing members I and connected by transverse rods or bolts 8. The spacing members and rods are arranged at any desired points and the sides of the leg 4 are connected together at are also substantially U-shaped are suitably secured to the upper ends of the legs 2 and3 and are linked into the top iron 5 by passing the top iron through loops formed by the top irons 6; This will enable the tripod frame to readily collapse for folding the hoist and also provides a rigid connection between the legs when the tripod is arranged for use as illustrated in Figure l of the drawing. A hanger 9 preferably consisting of a hook is suspended from the top of the tripod preferably by being linked into the top iron 5 and is preferably arranged between the top irons 6 as clearly illustrated in Figure 2 of the drawing. The top iron may be secured to the sides of the leg 4 in any other desired manner and any other suitable means may be employed to provide a hinged connection between the legs 2 and 3 and the legs' l to permit collapsing or folding of the supporting frame. 7

A block and tackle ll] of the ordinary construction is hung from the hanger 9 and its rope II which may consist of a sash cord or any other equivalent flexible member extends downwardly from the top of the block and tackle to a Windlass l2 journaled in suitable bearings on the sides of the leg 4 and consisting essentially of a drum or reel I3 having an operating crank or handle I l and provided with a ratchet wheel ill. The ratchet wheel l5 preferably consists of one of the sides or cheeks of the drum or reel and is engaged by a pawl which may be conveniently formed by a hinge l7 secured to one of the bars of the leg One leaf of the hinge is secured to the leg d and the other leaf constitutes the said pawl lb. The loose'leaf is adapted when swung upward out of engagement with the ratchet wheel E5 to lie against ,the inclined leg 3 and thereby retained by gravity out of engagement withthe ratchet when it is desired to permit the drum of reel of the Windlass to rotate freely. Any other suitable form of Windlass and ratchet may of course be provided.

The lower block it of the block and tackle is provided with a hook from which is suspended the sling [9 of the hive engaging clamp 20. The

sling i9 is provided with a cap 2i preferably consisting of a rectangular plate provided at its corners with apertures 22 and having a central hole 23. The corners of the plate are bent downwardly as clearly illustrated in Figure 4 of the drawing and an eye bolt 2 i is secured in the central hole of the cap and is detachably engaged with the hook 25 of the lower block It. Instead of employing the cap and the eye bolt 2 for connecting the sling members with each other and with the hook 25 of the lower block is the triangular loop 2! shown in Figure 7 may be employed. A triangular or circular loop or ring may of 1 course be used and the upper'ends of the sling members may be connected by snap hooks or any other suitable means with the triangular loop or ring and the triangular loop or ring may be readily engaged with the hook 25. Any other suitable means may be employed for connecting the sling members with the hoisting mechanism.

Four flexible sling members 25 are secured at their upper ends in the apertures of the corner portions of the cap 2i and these sling members may consist of wires, chains or any other suitable fle'xible'elements and they are provided at their lower ends with snap hooks 21 orother suitable means adapted to engage eyes of extension sections 23 or eyes or openings of the clamp. The

extension sections may be of any desired length and are designed for increasing the length of the sling members to enable the sling to a'ccommodate itself to a hive having any number of supers'stacked above the hive body. The sling members which converge upwardly are prefe'rably arranged in pairs at opposite sides of the hive as clearly indicated in Figure l of the drawing but the clamp may be positioned on the hive to arrange the sling members at the front and back of the hive as will be readily understood. The sling members may consist of chains, wires, cables or a combination of the same or any other ilx other suitable material may be employed as will be readily understood. The clamping members are provided intermediate of their ends with inwardly projecting lips 38 preferably consisting of metal plates suitably secured to the clamping bars 25! and adapted to fit into the usual hand hold or other holes in the hive body 3i and supers 32. Instead of employing lips for engaging holes or recesses in the hive body and supers cleats or blocks (not shown) may be secured to the hive body and the supers and the clamping bars may be arranged beneaththe blocks or cleats in 'engagement with the same but frictional engagement of the clamps with the hive body and the supers may be relied on from firmly connecting the said parts of the hive with the sling and the hoisting mechanism.

The ends of the clamping bars 25 may be provided with diagonal kerfs 33 in which are inserted corner irons 3E and preferably consisting of narrow plates and provided at their ends with suitable eyes or openings and 36. The openings 35 are adapted to be engaged. by snap or other hooks 3'! provided at the lower ends of the extension sections 28 or the snap or other hooks 2'! provided at the lower ends of the sling membore 26. The corner irons 54 are provided with central perforations 38' to permit fastening devices to be driven into or otherwise applied to the ends of the clamping bars and pass through the corner irons for permanently securing the corner irons to the end bars. The corner irons at the adjacent ends of the end bars may converge downwardly as shown so that the upper ends of the inclined corner irons project outwardly beyond the planes of the side faces of the clamping bars 29 so that the pull on the clamping bars by the sling members will cause the clamping bars to engage either the hive body or any one of the supers firmly and the inwardly projecting lips 30 which engage recesses or hand holes of the hive cooperate with the clamping bars ineffectually preventing the clamp from slipping when the Windlass is operated to lift one and all of the supers or the hive body. The corner irons when flat may be arranged either at an inclination or horizontally and various other means may beem ployed for connecting the sling members with the clamping bars and various means may be employed for adjustably connecting the clamping bars with each other.

When it is desired to inspectthe hive body the supers may be lifted as illustrated in Fi ure 1 of the drawing and they may be swung to one side and suitably secured in such position so as to afford ready access to the hive body for inspection of the same or other purpose.

The openings at the inner ends of the corner irons 34 of one of the clamping members has linked into it an eye of a hook 39 which adjustably engages a short chain it) which is linked into the inner eye 36 of the adjacent corner iron. The hook 39 and the short chain 49 constitute .ad-

justable means for connecting the bars 29 at each end of the clamp.

Instead of slitting the ends of the clamping 35 and 36 of the corner irons 34, but any other suitable means may be employed for this purpose.

When it is desired to weigh the whole or any portion of the hive a scale 43 of the ordinary construction may be interposed between the cap of the sling and the hook of the lower block N3 of the block and tackle.

The bottom cross piece which connects the to receive the foot of the operator. At the start of the lifting of an extra heavy load the operator "may place a foot on this bottom cross bar to steady the hoist. -This is unnecessary with ordinary lifting operations. i
