My invention relates to method of and machines for making brick and more particularly to meansfor placing the molded brick upon the pallets. I I

Heretofore it" has been the practice to fill themold one. bed plate and then'invert or turn the mold over in depositing it upon the pallet. Another method has been to fill the mold with the brick making material or mud while the mold rests upon a plunger and then remove the brick oy pushing or lifting the same off the plunger. These methods have provcn particularly objectionable when soft mud is used, due to the fact that the mud settles during the tilting or inverting step, and where the brick is lifted or pushed from the plunger a large percentage of broken, misshapen and otherwise damaged bricks are produced.

The object of my invention is to overcome the objections mentioned by placing the molded brick upon the pallet before taking the brick out of the mold and without inverting the mold.

Other and further objects and advantages of my invention will be apparent as the specification is considered in connection with the accompanying drawings, in which:

Figure 1 is a plan View of the device;

Figure 2 is a side view thereof;

Figure 3 is a plan View of a modification; and V Figure 4 is a side view of the device illustrated in Figure 3.

Referring more particularly to the drawings wherein like reference numerals refer to corresponding parts throughout the several views, 1 denotes a suitable base upon which is mounted an anvil plate or block 3, a pedestal 4 being employed for this purpose.

A pallet 5 of any ordinary and suitable construction rests upon and is supported by the anvil plate or block 3, the latter being provided with a recess 6 to receive the body of the pallet and maintain the top surface thereof flush with the top-7 of the anvil plate or block, the rolled edges 8 of the pallet 5 being accommodated between the forward and rear extensions 9 and 10 respectively of the anvil plate or block.

Resting loosely upon the top surfaces of the anvil plate or block 31s a thin flat smooth liner plate 11, preferably of tin, of suflicient length and width to substantially cover the pallet. It is upon this plate- 11 that the sec-- tional mold 12 is placed preparatory to the manually manipulated by filling and slicking operations, which are performed by any well known and suitable mechanism (not shown).

lVhen the mold 12 has been filled'with brick making material and the molded brick have been slicked, the filled mold is deposited directly upon the pallet by withdrawing .theli-ner )late-from between the mold andpallet, af ter which operation the mold is stripped from the brick by stripping mechanism (not shown).

The liner plate 11 is withdrawn from between the mold and the pallet by means of a lever 13 pivotally mounted upon the base 1 as at 14, at its lower end, and pivotally connected adjacent the handle portion 15 on its upper end to the rear end of the liner plate as at 16. Any suitable mechanical means (not shown) may be employed to actuate the lever 13, or the latter may be grasping the handle portion 15 thereof.

In Figures 3 and 4 I have illustrated a modified form of the invention adapted to be employed in a brick making machine wherein the stripping mechanism is located at a point removed from the filling and slicking station. In this form of the invention an anvil plate 3 is supported upon the base 1 by means of posts or uprights 4. The anvil plate 3 is formed with an enlarged or thickened rear portion 17 adapted to receive and support the sectional mold 12 during the filling and slicking operation.

The forward portion of this anvil plate 3 is cut away or reduced in thickness, to form a recess 18, adapted to'receive-the pallet 5 therein, thedepth of the recess being such that the top of the pallet is flush with the top of the enlarged portion 17 of the anvil plate.

As in the preferred form of the invention, a liner plate 11 is employed which is similar in all respects to the plate 11 with the ex ception that the former plate is of sufficient length and width to cover the enlarged portion 17'and to extend over the pallet receiving recess 18. It will thus be seen that the entire top of the anvil. plate 3, including the cilitate the placing of the mold 12 with brick therein upon the pallet 5. v

In practice the sectional mold 12 after the filling and slicking operations have been performed, is slid from A position forwardly along the top of the liner plate 11 by means of pusher arms 20 until the mold is in B ing the pusher arms, or the latter may be manually actuated.

7 Having thus described my invention, what I claim as my invention is: e I

1. A brick making machine comprising an anvil plate adapted to support a pallet there- 2. A "brick making machine comprising an anvil plate having a mold supporting surface and a pallet supporting surface at different levels, with mold and pallet thereon a liner plate between the mold and the mold supporting surface and extending over and above said pallet, means for moving the mold after the filling operation across said liner plate to a position thereon above said pallet," and means for withdrawin the liner plate from between the mold an the pallet.

In testimony whereof I affix my signature. ROY P. M, DAVIS,
