M 6 W W "T 8 6 4 MW "mu O on O M when the frame 19 is in its elevated position, as shown in Fig. 2 the mold members and the cores will be disposed in closed position, or with the mold ready to receive the cementitious material which forms the building blocks.

Pivoted at 787 9 to the leg members 11 are levers 80 81, the levers connected at their outer ends by a transverse hand bar 82. Projecting from the arms 2223 are bearings 83-84, and connected between these latter bearings and the levers 80 are links 8586, the links pivoted at their ends respectively to the bearings 8384 and the levers 8081. By this simple means it will be obvious that when the levers 8()-81 are in their downward position, as shown in Fig. 1, the frame 19 and its attachments will be in their lower positions, as shown in Figs. 1 and 3, and when the levers are elevated the frame 19 and its attachments will be in their elevated positions, as in Fig. 2 while the transverse connecting member 82 will engage beneath the projecting arms 30-31, and thus firmly lock the follower mechanism in elevated position, while at the same time the lock is easily broken by a slight outward pressure ap lied to the member 82. The follower member 19 is thus maintained when in elevated position against the under side of the frame 15, and by adjusting the post 13 through the medium of the set screws 17-18, the position of the frame 15 may be controlled to enable the lock device to operate with precision, andthus cause the proper cooperation of the parts. Thus by moving the levers 8081 by the end member 82 upwardly and downwardly the mold members will be opened and closed, as required, and the mold members locked in their closed position as above described. The core members 21 are provided with laterally extending bases, as shown, to increase their stability.

It will thus be obvious that a very simply constructed apparatus is provided in which building blocks may be quickly molded, and after the molding operation is completed and the material has sufficiently set the mold members and the cores may be quickly withdrawn, leaving the block ositioned upon the plate 15, and from whicfi it may be readily removed, and the a paratus arranged for the molding of other b ocks, and so on continu ously. By providing the side and end members of the mold structure of different thicknesses blocks of different sizes may be constructed, and by providing a plurality of the cores 21 of various sizes, and bottom members 15 having apertures 15 corres ending to the various sizes of the cores, b ocks of various sizes may be constructed with the same machine, as will be obvious.

By arranging the posts 13 in adjustable relations to the frames 10 and 15, the machine may be separated for shipment or transportation, and likewise for adjustment, as required.

Having thus described the nature of the invention, what is claimed as new is:-

1. In an apparatus of the class described, a supporting base, a stationary frame, guide elements spaced apart and connectim the stationary frame and the base, a fol ower frame movable upon said guide elements, mold supporting frames swinging from said stationary frame, movable links between said mold supporting frames and follower frame, levers swinging from said base and connected at their free ends by a transverse member adapted to bear beneath the follower frame when in elevated position, and links connecting said follower frame and lovers.

2. In an apparatus of the class described, a supporting base having spaced vertical sockets, guide elements movable in said sockets, means for securing said guide elements in their adjusted positions in said sockets, a stationary frame carried by said guide elements, mold supporting frames swinging from said stationary frame, a follower frame movable upon said guide elements, coupling devices between said follower frame and swinging mold frame, levers swinging from said base and connected at their free ends by a transverse member adapted to bear beneath the follower frame when in elevated position, and coupling means between said levers and follower frame.

3. In an apparatus of the class described, a supporting base, a stationary frame spaced from said base, a mold device comprising movable elements and carried by said stationary frame, a follower, connecting means between the elements of said mold and said follower, levers swinging from said base, a transverse member connecting the free ends of said levers and adapted to bear beneath the follower when elevated, and connecting means between said levers and follower.

In testimony whereof I affix my signature, in presence of two witnesses.

JOHN FISH.
