JOHN ALBERT FERGUSON, OF DENVER, COLORADO.

CONCRETE-BLOCK-MAKING MACHINE.

Application filed May 15, 1916.

To all whom it may concern:

Be it known that I, JOHN A. FERGUSON, a citizen of the United States, residing at Denver, in the county of Denver, State of iolorado, have invented a new and useful improvement in Concrete Block Making Machines, of which the following is a specification.

The object of my invention is to make a cheap efiicient concrete block making machine, that will make the best kind of concrete with a full water saturatedmixture, and make the several peculiar styles of blocks required and be easily arranged to make the variations in blocks that are needed to fill the requirements of given structure.

Reference will be had to the accompanying drawings in which:

Figure 1. is a front elevation of the machine. Fig. 2. is a plan View. Fig. 3. is an end elevation. Fig. 4. is a transverse section through the molding form and table line l-- l of Fig. 6. Fig. 5. is a similar view to that of Fig. t at one position of operation. Fig. 6. is a transverse View to that of Fig. at on line 6-6 of Fig. 3. Fig. 7. is a perspective View of one of the blocks made by the machine being the block used in the straight body portions of the wall. Fig. 8. is a perspective View of a block used at the corners of the wall. Fig. 9. shows the corner blocks.

Concrete block machinery heretofore used has generally required a mixture containing not too much water so that on removal from the machine the block would keep'its shape while the cement sets. Often not enough water is used and the blocks are defective and very porous, making a poor wall. The best concrete is made using plenty of water and I so design my blocks and machine that I can use just as plastic a mixture as will insure the best results.

In the drawing 1 indicates the frame of the machine which is made in any suitable manner and supports the main holding flask or mold form 2, which latter makes a part of the frame.

3 indicates the movable platen frame, which is only a frame work and supports the bottom or follow boards 1. The platen frame 3 is supported at its ends by blocks 5, supported in sliding contact with vertical rods 6, in the frame. A bell crank shaft 7 journaled in the frame at the bottom is connected by levers 8 at hinges 9 to links Specification of Letters Patent.

10, connected by hinge pins 11 to blocks 5 and frame 3, and actuates the frame 3 up and down as desired through the medium of the operating lever 12 fixed at 13 to shaft 7 at the right end of the machine.

7 The lowest position of the platen frame 3 is indicated by the dotted line position shown in Fig. 3. On the back of flask member there are hinge pins 14 held in lugs 15 on the flask, and hinged to these pins by any suitable lugs 16 there are pocket or segment mold members 17 provided with pocket or mold form spaces 18. The hinge lugs 16 of the pocket members 17 are slotted at 19 so that these mold members may be quickly lifted off and changed for others having variations in shape or location, of the pockets. Stop projections 20 are provided on the members 17 for retaining the members 17 in position as indicated by Fig. 5.

The members 17 that are shown in the figures have pockets of the form required to make blocks like that shown in Fig. 7. The blolclk of Fig. 8 is used at a corner of the wa In the use of the machine the members 17 are lifted as shown by Fig. 5 by means of a handle 33 and the table or platen frame 3 is lowered as shown by the dotted lines in Fig. 3, then a bottom or follow board 1 is placed on the frame 3 and the whole is lifted by lever 12 bringing the board up snugly under the open bottom of the mold frame 2, forming the bottom thereto, whereupon the concrete is filled in and tamped as is indicated by 24 Fig. 5, while the members 17 are in an upright position.

The concrete is a wet mixture of the best kind and the grouty portions settling down on to the board forming a full filled smooth non-porous face for the blocks.

When the tamping is completed as inclicated in Fig. 5 the members 17 are lowered over the main mold frame 2 as is shown by the other figures and then the concrete is filled into the pockets 18 and tamped down as indicated by 25 Figs. 4 and 6 forming a homogeneous connection with the main slab along the dotted line 26. When this tamping is completed the lever 12 is pulled forward lowering the frame 3 bottom board 1 and the block with them, the latter coming out of the mold as the board goes down, a slight taper to the sides of the mold facilitates the blocks movement out of the molds. WVhen the frame 3 is down to dotted position shown in Fig. 3. The board I with its burden of concrete is drawn out on the eX- tension portions 27 of frame 3 and removed to a place of repose, the board t remaining under the plastic block until it sets sulficiently to permit the board to be removed for further use. A number of boards 4 being required to keep the machine in active operation.

The links 10 are adjustable in their length by threads 28 and nuts 29 and when the lever 12 is thrown back bringing the links 10 and lever S on centerline, the board t will fit sufficiently tight under the mold form 2 as to prevent leakage of the grout along the bottom edges. A counterbalancing weight 30 holds the lever normally in an upright position when shoved back to full line position in Fig. 3. Springs 31 on guide rods 6 cushion the stopping of the frame 3 on its downward movement. Adjusting screws 82 permit the adjustment of the links 10 and levers 8 to get them in direct alinement for upward position of registration.

The wall made by my blocks is finished on the inside by the wooden or metal lathing being secured to the inside faces of projections 22 and 23, thus inclosmg hollow spaces between the projections.

The blocks as shown by Fig. 7 are shaped as to the location of the projections so that every other layer may be laid up breaking the joints at the ends and tying the wall together. The corner blocks being shaped to suit the requirements as shown by Fig. 9.

Surrounding the pockets 18 of the members 17 there are flanges 34c that act as a table for the reception of the concrete to be filled into the pockets 18, and at the same time these flanges act as a cover for the body of the main mold, not open to the pockets, to prevent the filling falling on to the main body portion of the block.

lVhen short blocks are to be made shorter than the length of the main mold frame a division wall is placed into the main mold chamber thus damming off the balance of the space. The dotted lines in Fig. 6 indicate such a division wall.
