In Figs. 1 and 2 the blocks 4 and 5 are shown as disposed in continua: tlon of blocks 4a and 5a, morlar joints 1 being provided between theend surfaces of-adjoinin blocks,

The operator by grasping the handles I8 is thus enabled to lift and carry the blocks 4 and 5 and toretain them in accurately spaced relation one to the other while they are placed in proper position on the wall under construction. :The accurate placing of the blocks is further facilitated by providing a spirit level 24 which is mounted on a bar 25 extending across the top of the frame and secured at. its ends to the bars 9. The end portions of the bar 25'are formed to embrace the bars 9 respectively and are held in position by suitable set screws. Thus the spirit level 24, which extends laterally of the blocks and in exact parallelism with their upper surfaces, affords means for adjusting the level of the blocks While they are held in the jig, thereby further facilitating the disposition of the blocks in' proper horizontal position as elements of the wall under construction. a

In using my device, the blocks of a pair ar placed sideby side on a suitable, substantially flat support and my improved jig and carrier is 'narily the successive pairs of blocks are placed at the'ends of previously placed blocks, such as the blocks 4a and 5a, afterthe plastic mortar I has been applied at the ends of the blocks 5a and 5a and after layers of mortar have been applied to the upper surfaces of the foundation or course of blocks below. The positions of the blocks 4 and 5 are then adjusted by reference to the spirit level 24 and such other guides as may be employed to properly locate the pair of blocks. Finally my device is removed from the blocks-after merely releasing the handles I8 to allow-the jaw members I3 to be retracted by gravity acting on the wedge members I5 and connections with the handles I8. The foregoing operation is repeated until the wall is complete.

It will be evident thatthe blocks when held in the grip of my device are accurately spaced, one relative to the other, and that the'work of handling and accurately setting. the blocks is greatly facilitated.

Having described my invention, whatlclaim as new and desire to protect by Letters Patent is: 1. A jig and carrier for building blocks com blocks disposed in horizontally spaced relation one to the other, fixed jaw members depending from said frame for engagement with opposite outer surfaces of the respective blocks so disposed, movable jaw members depending from said frame in the space between blocks for engagement with opposite inner surfaces of the respective blocks and handle means operatively connected to said movable jaw members to grip thev blocks between said fixed andlmovable jaw members.

2. A jig and carrier for building blocks comprising, a frame adapted to extend above the upper surfaces of a pair of said blocks with the blocks disposed in horizontally spaced relation one to the other, fixed jaw members depending from said frame for engagement with opposite outer surfaces of the respective blocks so disposed-movable jaw members depending from said frame in the space between blocks for engagement with opposite inner surfaces of the re-. spective blocks, wedge means for actuating said movable jaw members to engage said blocks and handle means operatively connected to said wedge means for actuating said r'novable ja members to engage the blocks.

3. A jig and carrier for building blocks comprising, spaced parallel frame members adapted to extend across the upper surfaces of a pair of 1 said blocks with the blocks disposed in hori-,

zontally spaced relation one to the other, a pair of fixed jaw members depending from each of said frame members for engagement with opposite outer surfaces of the respective blocks so' "disposed, a pair of movable jaw members depending from each of said frame members in the space between blocks for engagement withopposite inner surfaces of the respective blocks and a handle operatively connected to each pair of -movable jaw members to actuate them to engage the blocks. 7

4. A jig and carrier for building blocks comprising, a frame adapted to extend above the upper surfaces of a pair of said blocks with the.

blocks disposed in horizontally spaced relation one to the other, fixed jaw members depending from said frame for engagement with opposite. outer surfaces of the respective blocksso disposed, a support for movable jaw members dei from said frame for engagement with opposite outer surfaces of the respective blocks so dis- 5 posed, a support for movable jaw members depending from said frame in the space between blocks, movable jaw members carried by said support for engagement with opposite inner surfaces of the respective blocks, wedge means for actuating said movable jaw members to engage said blocks and handle means operatively connected to said wedge means to grip the blocks between. a

said fixed and movable jaw members.

6. A jig and carrier for placing a pair of build-. ing blocks in fixed horizontally spaced relation one relative to the other in position as elements of a wall, the improvements which comprise, frame members adapted to extend crossways and above the upper surfaces of the building blocks of a pair, a plurality of fixed jaw members depending in fixed spaced relation one to another from each of said frame members for engagement with substantially vertical surfaces of each of said blocks when said blocks are in predetermined spaced relation one to the other, rigid supports depending from each of said frame members in fixed spaced relation to the several fixed jaw members, a movable jaw member carried by each of said supports for engagement with the adjacent surface of one of said blocks, sub stantially vertically movable wedges disposed to actuate the several movable jaw members laterally to grip said blocks, a handle carried by each of said frame members and means operatively connecting said handles to the several wedges whereby said movable jaw members may be actuated to grip and accurately space said blocks in contact with the several fixed jaw members when lifting force is applied to said handles.

7. The jig and carrier in accordance with claim 6 in which said means operatively connecting the handles to the wedges comprise threaded means depending from the handles whereby the elevations of the wedges relative to the handles may be adjusted.

8. A jig and carrier for placing a pair of building blocks in fixed horizontally spaced and level relation one relative to the other in position as elements of a wall, the improvements which comprise, a frame having members adapted to extend crossways upon the upper surfaces of the building blocks of a pair, each of said frame members having normally horizontal surfaces for engagement with normally horizontal top surfaces of both of said blocks, a plurality of fixed jaw members depending in fixed spaced relation one to the other from each of said frame memhere for engagement with substantially vertical surfaces of each of said blocks when said blocks are in predetermined spaced relation one to the other, movable jaw members depending from each of said frame members adjacent to substantially vertical surfaces of each of said blocks opposite to the several fixed jaw members, handle means operatively connected to said movable jaw members to grip and accurately space said blocks in contact with said fixed jaw members and with the top surfaces of said blocks in contact with said horizontal surfaces of said frame members and a spirit level fixed on said frame in precise parallel relation to said horizontal surfaces thereof and operative to facilitate the setting of the pair of blocks held in the grip of said jaw member in a mutually level position as elements of a wall.
