BLOCK-MOLDING MACHINE.

Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed February '7, 1907. Serial No. 356,211.

To all whom it may concern:

Be it known that I, MILTON J. PALMITER, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Block-Molding Machines, of which the following is a specification.

This invention relates to block molding machines, and it has for an object to provide a machine of this type which is inexpensive to manufacture, simple in operation and durable in use.

With this and other objects in view the invention consists in the parts and combina tion of parts hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the appended claims.

In the drawings c-Fi ure 1 is aperspective view of the machine reac ly for moldin Fig. 2 is a perspective view showing the ividin partition withdrawn and the front side wal lowered. 'Fig. 3 is a top view with the hopper or container removed. Fig. 4 is a view of the end of the machine opposite to that shown in the perspective views.

Referring more particularly to the drawings, 1 indicates a frame provided with a hopper or container 2 for the loose material from which the blocks are to be made, the container or hopper having its bottom wall closed and its front wall open so that the material may be removed therefrom and fed into the mold arranged below but in advance of the hopper or container.

The mold comprises a removable bottom or bed plate 3, a front side 4, hingedat 5 to the frame at its lower edge to swing forwardly, and a plurality of vertical partitions 6 connected at their rears by a back side 7. These vertical partitions or dividin plates 6 are arran ed to slide rearwardly off the bed plate an for this purpose a board 8 is positioned in the rear of and in the plane of the bed plate 3.

To move the dividin plates to and from their position over the ed plate 3, there is provided the following means. A rock shaft 9 is arran ed on the front of the frame below the mold and has connected to one end an operating lever 10. Also secured to said rock shaft 9 is a pair of vertical arms 11 which are connected by links 12 with a pair of levers 13 secured at their lower ends to an oscillatory shaft 14 which is arranged below the hopper 2. levers are connected by links 15 with the rear side 7 of the mold.

The mold front side 4 is provided with a plurality of vertical grooves 16 to receive the front ends of partitions 6, and is weighted at 17 so that when released as hereinafter described, it will drop forwardly. The mold side is held up against the ends of the partitions by latches 18, pivoted to frame 1 and adapted to engage keepers 19 on opposite ends of front side. These latches are curved in such a manner that lugs 20, one on the operating lever 10 and the other on a lever 21 secured to that'end of shaft 9 opposite the operating lever, engages the latches and move them to release the front side when the operating lever 10 is moved to shift the partitions 6 rearwardly.

When the parts are in the position shown in Fig. 1 the mold units are filled by material fed from hopper 2. After the usual tamping, the lever 10 is moved rearwardly, causing lugs 20 to lift latches and thepartitions to be shifted to the rear. When the latches release the front side it drops by gravity to the position shown in Fig. 2. The bottom plate 3 with the blocks is then lifted and carried to a place where the blocks are dried, and another bottom plate is fitted to the machine. The front side is now lifted by hand and the lever 10 is moved forwardly carrying the partitions therewith and permitting the latches to drop and lock the front side. The parts are again in position for molding.

It will be noted that I provide a means for operating the sliding partitions, connected to the locking means of the front side to release tllile latter and permit it to open automatica y.

Having thus described my invention, What I claim and desire to secure by Letters Patent is 1. A block molding machine comprising a bed plate, front and rear sides, the front side being hingedly mounted and movable out of operative position automatically and the rear side being slidable into and out of operative position, a plurality of partitions connected to the rear side and movable into and out of cooperative relation with the hinged side, and means for moving the par-' At their upper ends these.

operative position automatically, a plurality of partitions, locking means for the hinged side, and means for moving the partitions, connected with the locking means to release the front side.

3. A block molding machine comprising a bed plate, a hinged front side movable to inoperative position automatically, a plurality of sliding partitions, pivoted latches for holding the front side against movement, and means for moving the partitions, connected to the latches to release the front side.

4:. A block molding machine comprising a hopper open at its front; a mold arranged below and in front of the hopper and formed of a bed plate, a hinged and weighted front side, a plurality of sliding partitions, a back side connecting the partitions, and latches ,for holding the front side against the ends of the partitions: an oscillatory shaft arranged below the mold and connected to the sliding partitions; and a pair of levers having means to engage the latches to operate them.

5. A block molding machine, comprising a bed plate, a downwardly swinging front side, latches for the front side, movable partitions for the bed plate, an oscillatory shaft below the bed plate, levers on the shaft, adapted to operate the latches, and connection between the shaft and the movable partitions for moving the latter.

6. A block molding machine comprising a bed plate; a hinged front side movable to inoperative position automatically; a plurality ofpartitions; locking means for the hinged side; means for moving the partitions, and

means whereby the movement of the partitions out of operative position will effect a release of the aforesaid locking means of the front side.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
