Oct. 22, 1946. 1 F. A. DOSTAL BUILDING BLOCK LIFTER Filed June 20, 1945 Patented Oct. 22, 1946 OFFICE BUILDING BLOCK LIFTER Frank A. Dostal, New Ulm, Minn.

Application June 20, 1945, Serial No. 600,483

4 Claims.

readily inserted into the openings of the block I and which may be readily removed from said opening after the block has been lifted or carried to the desired position.

Another object of my invention is to provide a device for the purposes above described which will grip the block in such a tenacious manner upon lifting of the handle, that it is impossible for the block to slip away while being carried.

The above and other objects of my invention will become apparent from the following specification and the attached drawing.

Referring to the drawing, wherein like characters indicate like parts throughout the several views:

Fig. 1 is a top plan view of my novel device, inserted into one of the openings of a conventional building block;

Fig. 2 is a side view of the block and lifter illustrated in Fig. 1, partly in elevation and partly in section, a portion thereof being broken away; and

Fig. 3 is a rear elevation of my novel device.

Referring with more particularity to the drawing, the letter A indicates a building block of the conventional type having a plurality of vertical openings B therein.

My novel lifter has a shank portion I which is bent substantially at right angles at 2 to provide a handle portion 3. Fixed to the lower end of shank I is a gripping lug in the form of arectangular plate 4.

As will be observed, the shank I is secured to approximately the center of gripping plate 4' so that a portion thereof projects downwardly and backwardly under said handle at an obtuse angle with respect to said shank, and a portion thereof extending upwardly and forwardly at an acute angle with respect to said shank I.

Fixed to the intermediate portion of said shank I and projecting substantially at right angles thereto in a direction under said handle'portion 3, is a stop lug 5.

Operation When it is desired to carry a block with this novel lifter, it is first advisable to turn the block so that the openings thereof are in a vertical position as illustrated in Figs 1 and 2. The shank portion I with the gripping plate 4 secured thereto are then inserted into opening B to a depth where the stop lug 5 rests upon the top surface of the block as illustrated in Fig. 2. To facilitate insertion of the shank and gripping plate 4 into the opening B, the extreme outer end of handle portion 3 is lowered, thereby tending to put the gripping plate 4 in a position more nearly approximating the vertical, thus bringing the forward and rearward edges of the gripping plate away from the sides of the opening B.

When the outer end of handle 3 is then lifted up, the gripping plate 4 tends to straighten out, more nearly approximating the horizontal, to the point where the extreme forward and rear edges thereof come into contact with the side walls of the opening B of the block A.

It is obvious that the greater the weight of the block A, the more firm will be the grip of the gripping plate 4 against the sides of the block. It will be readily appreciated that under such circumstances, it is virtually impossible that there be any tendency of the block to slip away from the gripping plate while the block is being transported.

Furthermore, the width of thegripping plate 4 provides a sufiiciently wide gripping surface against the walls of the opening B to assure freedom of lateral rocking motion of the block A during the carrying operation.

While I have shown and described a commercial structure of my invention, it is obvious that the same is subject to certain changes and modifications all within the scope of the appended claims.

What I claim is:

1. In a lifting device for building blocks and the like, having vertical openings therein, a shank bent substantially at right angles to provide a, handle portion, and an enlarged gripping plate fixed to the lower end of said shank and extending backwardly under said handle at an obtuse angle to said shank.

2. In a lifting device for building blocks an the like, having vertical openings therein, a shank bent substantially at right angles to provide a handle portion, an enlarged gripping plate fixed to the lower end of said shank and extending backwardly under said handle at an obtuse angle to said shank, and a stop lug fixed to the intermediate portion of said shank and extending outwardly under said handle portion.

3. In a lifting device for building blocks and the like, having vertical openings therein, a shank having its upper end bent at substantially right angles to provide a handle, a rectangular stop plate fixed to the lower end of said shank, a

4 portion of said plate extending backwardly under said handle at an obtuse angle to said shank and. a portion thereof extending forwardly and upwardly at an acute angle to said shank.

4. In a lifting devise for building blocks and the like, having openings therein, a shank having its upper end bent at substantially right angles to provide a handle, a rectangular stop plate fixed to the lower end of said shank, a portion of said plate extending backwardly under said handle at an obtuse angle to said shank and a portion thereof extending forwardly and upwardly at an acute angle to said shank.
