LUKE T. LOlVE. OF BRISTOL, TENNESSEE, ASSIGNOR OF ONE-THIRD TO HOMER E. JONES AND ONE-THIRD TO CHARLES F. GAUTHIER, OF

BRISTOL, TENN Specification of Letters Patent.

Patented Sept. 4, 1906.

Application filed October 11. 1905. Serial No- 282.304-

To all whom, it may concern:

Beit known that I, LUKE T. Lows, a citizen of the United States, residing at Bristol, in the county of Sullivan and State of Tennessee, have invented a new and useful Cement- Block Machine, of which the following is a specification.

This invention relates to apparatus of that class employed for the mnufacture of building and other blocks from concrete or other plastic material.

The principal object of the invention is to provide a novel form of mold-box in which the parts moved to and from molding position will be automatically closed or opened, a single movement of the operating mechanism being all that is necessary to move the block to discharging position or to return the parts to filling position.

A further object of the invention is to provide a machine of this type in which the mold-box as a whole is movable vertically from the filling or molding to the discharging position and in which the side and end plates of the box have pivotal connections with the bottom or carrier of the box and with the stationary frame of the apparatus, said connections being so arranged that on upward movement of the mold-box the sides and ends will be moved down to approximately horizontal pofition, while on downward movement of the boX the sides and ends will be moved to vertical position.

A still further object of the invention is to provide a device of this character thatmay be readily adjusted for the formation of hlocks of any size and shape and in which plates of different type may be employed in order to change the molded designs of the ex posed faces of the blocks.

A still further object of the invention is to provide a machine of this type in which by the insertion of suitable partitionplates a large number of smaller blocks or bricks may be formed at a single operation.

WVith these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any, of the advantages of the invention.

In the accompanying drawings, Figure 1 is a sectional elevation of a block-molding machine constructed in accordance with the invention, the mold-box being shown in filling or molding position. Fig. 2 is a similar view with the parts in discharging position. Fig. 3 is a plan view of the machine, portions being broken away and the side and end plates being removed in order to more clearly illustrate the construction. Fig. 4 is a detail plan view of the mold-box provided with partition-plates for the formation of smaller blocks or bricks. Fig. 5 is a detail view of one form of cornice block which may be made by the machine.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawmgs.

The working parts of the machine are supported on a suitable frame 10, the lower portion of which has bearings for a transverselydisposed rock-shaft 11, and at one end of the shaft is a lever 12, by operating which the mold-box may be moved to and from discharging position and opened and closed, all of the parts being operated at a single move ment.

The frame is provided with a pair of horizontally-disposed bars 15, that are connected by transverse bars 16, the latter forming supports for a core-carrying plate 17. This plate is provided with a number of slots 18 for the passage of securing-bolts 19, by which cores 20 of different shape and size may be secured in place, the positions of the core members and their contours depending on the character of the block to be made.

The inner faces of the end portions of the frame are provided with vertically-disposed guiding-ribs 22 for the reception of grooved guiding-blocks 2-3, that are secured to or formed integral with the main bottom plate 24 of the mold-box, said plate being substantially rectan ular in general coutour and provided with central openings for the passage of the cores carried by plate 17. This bottom plate is provided with a numb er of undercut grooves 27, that are arranged for the reception of pivot-blocks 28, that may be moved within the grooves toward and from the center of the mold-box in order to increase or decrease the size of the block to be made, and when adjusted the slide-blocks may be locked in position by screws 29. Two or more of these blocks are employed at each side and each end of the plate 24 and serve as pivotal supports for the side and end members of the mold-box.

On the upper rail 31 of the frame are arranged a number of brackets 82, that are provided with slots 33 for the passage of securingbolts, the slots permitting adjustment of the brackets toward and from the center of the frame. These brackets are connected by pivot-links 34 to lugs 35, arranged at the up per edges of the side and end members of the mold-box, and during the movement of the latter from the lowest or molding position (shown in Fig. 1) to the discharging position (shown in Fig. 2) the links will serve to draw the side and end members outward, the latter assuming an approximately horizontal position and freeing the block, so that it may readily be removed and carried to the drying or setting floor. On movement from the position shown in Fig. 2 to the position shown in Fig. 1 the links serve as guides for closing and the contour of the block.

the side and end members and adjusting the mold-box to position for the reception of another quantity of plastic material.

The bottom plate 24 serves as a support for a removable pallet 36, having suitable open in s for the passage of the cores, a separate pa let-board being employed for each block made and the pallets being specially shaped to correspond to the arrangement of the cores These pallets are usually formed of wood or of metal that is galvanized or coated with a non-corrodible material in order to prevent injury to a molded block, and immediately before the mold-box is closed a fresh pallet is inserted to receive the plastic material.

The open frame or plate 24 is provided with a cross-bar 43, that is extended up above the level of the margin of the plate and is provided with a circular lug 44, arranged to enter a circular recess formed in the bottom of the pallet, so that when the molded block and pallet have been elevated to the position shown in Fig. 2 they may be turned around at a right angle, as shown by dotted lines, to permit the more convenient removal of the block and pallet from the machine.

In order to facilitate movement of the mold-box to discharging position, the rockshaft 11 is provided with a counterweight 40, that is normally arranged above the level of the shaft during the filling of the mold.

After the material has been shoveled in and mold-box being elevated and the counterweight assisting in the operation.

By changing the face-plates blocks having any desired design may be made, and, if desired, a large number of smaller blocks or bricks may be made at a single operation by placing within the mold-box a multiple partition 41 of the character shown in Fig. 4.

Having thus described the invention, what is claimed is 1. The combination with a frame, of a stationary corecarrier, a core supported thereby, a vertically-movable bottom plate, side and end walls pivotally connected thereto, links connecting the upper portion of said plates to the frame and arranged tooccupy an approximately horizontal position during the filling and tamping of the mold, and to effect positive outward and inward movement of said plate, and means for raising and lowering the mold.

2. The combination with a frame, of a stationary core-carrier, a core supported thereby, a mold-box guided by the frame and including a bottom plate and side and end plates, said bottom plate being provided with a plurality of grooves, pivot-blocks adjustably mounted in said grooves, and to which the lower edges of the side and end plates are pivoted, brackets adjustably secured to the upper rail of the frame, and links connecting said brackets to the upper edges of the side and end plates, whereby on raising of the mold-box the plates will be moved outward to approximately horizontal position, and on lowering of the box will be moved in ward and locked in closed position.

3. In a bloclcmolding machine, a moldbox including a removable pallet, and a support therefor, the pallet being mounted for revoluble movement with respect to its sup port to facilitate the discharge of the block.

4. In a block-1nolding machine, a moldbox including a revolubly-mounted pallet, and a pallet-support, the support and pallet being provided with interfitting lug and 1socket portions to permit turning of the pal- In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
