BODY TRANSFER HOIST George E. Pentecost, Milford, Ill.

Application October 29, 1952, Serial No. 317,397

3 Claims. c1. 254-8) This invention relates to body transfer hoists, and more particularly to hoists adapted to lift a body from one resting place, move it into position over another resting place, and lower it onto the second resting place.

An object of this invention is to provide an improved device of this character which is efficient and easy to operate and which is comparatively inexpensive to manufacture.

Another object is to provide a device of this character having a novel supporting base adapted to be adjusted so as to fit under various tables, casket pedestals, and other resting places.

Another object is to provide a device of this character having a novel hydraulic lift mechanism.

Other objects will become apparent from the detailed description following, which refers to the appended drawings, in which:

Figure 1 is a view in elevation from in front of one embodiment of my improved body transfer hoist, show ing in broken lines a body supported thereby.

Figure 2 is a view in side elevation of the same hoist.

Figure 3 is a plan view of the same hoist, showing in broken lines the base legs in their fully spread position.

Figure 4 is an enlarged fragmentary view substantially along line 44 of Figure 1, showing a detail of the leg spreading mechanism.

Figure 5 is another enlarged fragmentary view along line 55 of Figure 4, showing another detail of the leg spreading mechanism.

Referring now to the drawings, in which like numbers refer to like parts, one embodiment of my invention is illustrated consisting of an hydraulic body transfer hoist generally designated 19, including a horizontal base, generally designated 20, which comprises a rigid rectangular frame, generally designated 21 at the rear of hoist 10, and a pair of horizontal legs 22 and 23 pivoted at their rear ends respectively to vertical hinge pins 24 and 25 in the rear corners of frame 21. Legs 22 and 23 are thus pivotally mounted to the rear corners of frame 21 for horizontal swinging movement about said rear corners, which are also the rear corners of body transfer hoist 10.

Frame 21 has side rails 27 and 28, a front rail 29, and a rear rail 31. Legs 22 and 23 are much longer than side rails 27 and 28, and extend to the front of hoist 10, beyond the center of body support means 30, as best seen in Figure 2.

Base 20 is supported above the floor by means of casters mounted under the rear corners of frame 21 at 32 and 33, and under the front ends of legs 22 and 23, at 34 and 35 respectively. Thus hoist may be moved about on a floor.

Means is provided for spreading legs 22 and 23 apart in the manner illustrated in broken lines in Figure 3, which will now be described. A horizontal shaft 36 is rotatably mounted in frame 21, with its ends extending beyond front and rear rails 29 and 31 as best seen in Figure 4. A lever 37 is fixed on the rear end of shaft 36, and a transverse bar 38 on the front end, extending 2,739,733 Patented Mar. 27, 1956 ICQ.

the top of mast 40 is a boom which extends approximately horizontally toward the front of body transfer hoist 10. Boom 50 is preferably forked as at 51, so as to terminate ina forked front or outer end 52--52, as best seen in Figure 3. Depending from the outer or front double end of boom 50 is a body support means 30, which may be suspended by chains 53. The structure of body support means 30 is not a part of the present invention. It is believed that its use with transfer hoist 10 will be apparent from the drawings, and that it is unnecessary to describe it.

Mechanism is provided for raising and lowering boom 50 which will be described hereinafter. In order to obtain a substantially straight lift of body support device 30, extensions 54 are provided below the forked end of mast 50 to hold chains 53 at substantially the same radius from pivot 47 within the range of lift of boom 50.

A shelf 55 is secured to mast 40 on which is mounted a jack 60, from which extends upwardly a lifting or piston rod 61. Supported by piston rod 61 is a sliding member 70 comprising a vertical member 71 to which are secured,

as by welding, a pair of collars 72 and 73. These collars are slipped over the top of mast 40 in assembly (before stay 44 is attached) and have a freely sliding fit with mast 40. A lug 74 welded to one of the said collars provides a pivot 75 for the lower end of a connecting rod 76 the upper end of which is pivotally connected at 77 to boom 50 intermediate its ends. Pivot 77 is placed relatively close to pivot 47 as best seen in Figure 2, so as to multiply the throw of the front or outer end 52 when jack is operated.

Jack may be a hand operated hydraulic jack of conventional design having a pump handle 78 for lifting, and a release valve operable by a stern and knob 79 for lowering.

The manner of making and assembling this hydraulic body transfer hoist will be obvious to those skilled in the art from the drawings and foregoing description. Similarly, it is thought that the manner of using the hoist will be apparent. By moving lever 37 the horizontal legs may be adjusted to the required amount of spread so as to enable the operator to fit the base under a body rest, with chains 53 centered over the body to be transferred. Body support means 30 is strapped to the body and hooked to appropriate links of chains 53, the height of hooking onto the chains being chosen so as to make best use of the available lift range of the hoist. The hydraulic jack is then operated to lift the body clear of the body rest which has been supporting it. The entire body transfer hoist is then pushed on its casters into position with the body above the new resting place, the lever 37 being operated as may be necessary to avoid obstructions under the new resting place. The hydraulic jack is then lowered, lowering the body onto the new resting place.

An important feature of my invention lies in the method of mounting the spreadable legs pivotally at the extreme rear corners of the hoist, as at 24 and 25. This permits the maximum spread of legs 22 and 23 while still keeping their supporting ends safely in front of or beyond the outer or front end 5252 of boom 50, as best seen at 81 and 82 in Figure 3. Pivoting the spreadable legs at the rear corners of the hoist also makes possible the convenient and novel leg spreading mechanism.

This body transfer hoist has been found to be strong, efficient, and easy to operate. It can be manufactured at substantially less cost than similar hoists riow entire market. It has a lift of about 30 inches, but longer chains than those indicated in thedrawings permit a liftfrom any height.
