MEANS FCR HANDLING CONCRETE BLOCKS.

Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed January 25.1906. Serial En. 297,903.

T0 all whom it 11i/Ly concern:

Be it known that I, HARVEY Z. KLINE, a citizen of the United States, residing at Indianapolis, `in the county of Marion and State specification.

This invention relates to improvements in means for lifting building-blocks or the like having an opening therein and the object is to provide a handle which can be readily attached to the block and removed therefrom with ease and celerity after the block has been placed in the desired new position.

I accomplish the object of the invention by the mechanism illustrated in the accompanying drawings, in which- Figure l is a view in longitudinal vertical section ofca hollow concrete building-block having my invention applied thereto and shown in full lines in position for use as a handle and in dotted lines as it will appear at the time of the insertion and removal. Fig. 2 is a view in perspective of a concrete block having two openings similar to the block shown in Fig. 1, in one of which openings my improved lifting device is placed; and Fig. 3 is a perspective view of one of'my lifting devices in proper position for insertion into the opening of a block. Y

Like characters of reference indicate like parts throughout the several views of the drawings.

4 is a buildingeblock, such asis commonlyT made and used for building purposes out of concrete. It has the two vertical openings 5, in which openings my improved lifting deviceis inserted foruse. Two of these lifting devices, one for each opening, will be used in carrying each building-block, and as these devices are the exact duplicate of each other it will only' be necessary here to describe one of them, it being understood that the same description will apply to both. c

6 is a block of any suitable material, such as wood or metal, (here shown as wood,) of a size and shape to enter one of the openings 5 u This block 6 will be small enough to enter the opening 5 freely, and it may be considerably smaller without interfering with the operative character of the device. Secured to opposite sides of the block 6 are the parallel iron straps 7, having` perforations at their upper ends to receive the pin S, by means of which the handle-bar 9, preferably formed out of gas-pipe or other metal tubing, is pivotally secured to said straps 7 Also fastened to the upper portion of the block 6 near the opposite edge of the block from the extension of the straps 7 is the metal loop 10. The purpose of this loop is to limit the upward movement of the inner end of the handle 9.

The above-described lifting device is inserted in the building-block to be lifted by taking hold. of the handle-bar 9 with the hand of the operator graspingv ,the bar 9 between the pivot 8 and the loop l0. Thus held the block 6 is lowered into the position shown in Fig. l, whereupon the handle-bar is allowed to drop from the position shown in dotted lines in Fig. 1 to the position shown by the full lines in said figure. Then by the operator taking hold of the outer end of the handle-bar 9 the inner end will form a fulcruin against themiddle of the building-block, and a further upward pull on the handle 9 will cause the block 6 to swing out and bind against the outer end of its opening 5. It will thus be noted that the opposite or inner vertical edge of the block 6 is not in contact with the wall of the opening 5, and hence the close fit of the block 6 in the opening 5 is not necessary. After the block has been placed in the desired position the lifting device will be capable of easy and immediate removal by the operator taking hold of the bar 9 again between the pivot 8 and the loop 10. The ease with which the lifting device may be placed in position in the building-block and removed therefrom and the positive and certain hold which it obtains on the block are the special points of advantage and merit in my invention.

I-Iaving thus fully described my invention, what I claim as new, and wish to secure by Letters Patent of the United States, is-

1. A means for lifting a building-block or the like having an opening therein comprising an engaging block smaller` than the opening and adapted to be inserted therein, so as to bear against the outer end of the opening, and a handle fastened to the engaging block and bearing at its inner end upon the building-block forming a fulcrum about which the IOO 1o pivotally secured to said handle-supports 15 wall of the opening.

engaging block` will move b lifting up on the outer end of the handle to bind said engaging block against the outer wall of the opening.

2. A means for lifting a building-block or the like having an opening therein, comprising an engaging block smaller than the opening and adapted to be entered therein7 handle-bar supports secured to and extending `above the engaging block and a handle-bar whereby its inner `end may be. brought into Contact with the building-block and the engaging block swung around said Contact into binding engagement against the outer end 3. A means for lifting a building-block or A the like having an opening therein, comprising an engaging block smaller than the opening and adapted to be entered therein, a handle pivotally secured to and above the engaging block and having its inner end adapted to bear upon the top of the buildingblock and a loop attached to the engaging block at the inner edge of the latter said loop surrounding the handle.

In witness whereof I have hereunto set my hand and seal, at Indianapolis, Indiana, this 12th day of January, A. D. 1906.
