GEORGE WVETTLAUFER, OF STRATFORD, CANADA.

Specification of Letters Patent.

Patented July 3, 1906.

Application filed December 28.1905. Serial No. 293,651.

1'0 and whom it may concern:

Be it known that I, GEORGE WETTLAUFER, a subject of the King of Great Britain, residing at Stratford, in the Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Machines for Making Brick and Artificial Stone; and I do declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in machines for manufacturing bricks, artificial stone, building-blocks, and the like.

The object of the invention is to provide a machine of this character in which bricks, stones, or blocks may be quickly molded, pressed, and polished.

With the above and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an end elevation of a molding-machine constructed in accordance with the invention. Fig. 2 is a front side view of the same. Fig. 3 is a top plan view with the pressing mechanism removed. Fig. 4 is a longitudinal vertical sectional view, and Fig. 5 is a transverse vertical sectional view.

Referring more particularly to the drawings, 1 denotes a supporting frame or table, which consists of side pieces 2 and end pieces 3, connected at their corners to supportinglegs 4, thus forming an open frame or table. Adapted to rest upon the table or frame 1 are two or more plates 5, which may be formed of metal or other suitable material and which cover the whole surface of the framework. The plates 5 are provided with vertically-disposed apertures or'slots 6. On the plates 5 adjacent to the rear side of the machine is arranged an upwardly-projecting cross-bar 7, in which is formed a series of apertures 8. Adapted to be placed upon the plates 5 is a pallet-board 9, in which are formed apertures or slots 10, adapted to aline with the apertures or slots in the plates 5.

Arranged in the frame 1-is a series of two or more end-forming plates or bars 12, secured beneath the top plates 5 by means of cross rods or bars 13, which rest upon a. supporting-rod 14, the ends of which project through slots 15 formed invthe end boards or pieces 3 of the frame. The projecting ends of the rod 14 rest upon operating-levers 16, pivotally mounted on each end of the frame 1, as shown. The levers 16 are adapted to be raised and lowered, thereby raising and lowering the end-forming plates or bars 12, as will be understood. The levers 16 when in an elevated position are engaged with brackets 17, secured to the ends of the frame, as shown. In the end-forming plates 12 are formed apertures or passages 18, which aline with the apertures 8 in the rear cross-bar 7. When the end-forming plates are raised and lowered by the levers 16, they are adapted to work through the slots in the plates 5 and pallet-board 9 and when in operative position project upwardly above the palletboards 9 to a distance equal to the thickness desired for the bricks or stones to be molded. Slidably mounted on the pallet-boards 9 and adapted to Work through the passages in the rear cross-bars 7 and the end-formin bars or plates 12 are side-forming bars or p ates 19. Said plates or bars 19 are connected together at their rear ends by tie-rods 20. The ends of the tie-rods 20 are connected with and adapted to work in a longitudinally-disposed slot formed in the operating-levers 21, the lower ends of which are pivotally connected to the rear legs of the supporting-frame, as shown. Secured to the levers 21 are forwardly-projecting handle-bars 22, on the outer ends of which are arran ed handles 23, by means of which said hand e-bars and levers may be swung upwardly and rearwardly, thereby sliding the side-forming plates or bars 19 rearwardly through the passages in the rear cross-bar7 and end-formingbars of the mold. By thus connecting the levers 21. and the side-forming plates or bars 19 said bars will be moved rearwardly in a horizontal plane and when moved out of this position are adapted to be supported upon brackets 24, secured to the rear side of the machine, as shown.

Hingedly connected to one or the other ends of the frame 1 upon a bracket 25 is a pressing device 26. This device is here shown as and preferably consists of parallel arms or bars 27, which curve downwardly at right angles at one end of the machine, where they are pivotally connected to the bracket 25, as shown. Secured to the horizontal portions of the arms or bars 27 are a series of pressing-blocks 28, arranged in such position that when the arms 27 are swung downwardly IIO onto the mold said blocks will enter the spaces formed by the end and side forming plates or bars 12 and 19. The blocks 28 are of such size as to clearly fit said spaces.

Hingedly connected to the rear cross-bar 7' isa hopper 29, into which a cement, clay, or similar material may be placed preparatory to filling the mold-spaces between the end and side forming plates. 7

In operation the side and end forming plates bein arranged in operative position as hereinbe ore described, the cement or clay is placed therein and rammed down by means of a suitable tool, after which the surplus material remaining above the plates is scraped off. The pressing device is then 7 brought down upon the blocks inthe spaces 7 and the upper surface of the same is smoothly pressed by the blocks 28. After the blocks ave been thus formed the levers 16 are lowered, thus lowering the end-forming plates through the slots in the pallet-boards and plates 5, after which the side-formin plates are retracted at the rear of the machine by the operating -levers 21, as hereinbefore described. In thus withdrawing the side and end forming plates the same slide over the side surfaces of the blocks and impart a polish I which may be used thereto. After the side and end forming plates have thus been removed the pallet board containing the finished block is lifted from the plates 5 and another pallet-board arranged in its place. and side formin I plates, pallets, and presser blocks may be 'ormed hollow to form compartments for receiving steam or other heat in accelerating the drying and hardenin of the blocks.

From the oregoing description, taken in connection with the accompanying draw ings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined by the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
