COMBINED BRICK MOLD AND PRESS.

Application filed March 3,1926. Serial No..91,976.

The present invention relates to a combined mold and press and has forits principalobject to provide a structure 'for molding and pressing bricks. in an expeditious manner so that'the work may be done quickly and; with a minimum amount of labor.

Another very important object of the invention is to provide a device of this nature m which .will allow an operator-to place the same in a supply of wet material such as concrete to mold the proper amount thereof and press the same and then lift the device from which time the bricks may be released from the device for drying and setting purposes. A still further very important object of simple in its construction, inexpensive to manufacture, strong, durable, and light,

handy, and otherwise well adapted to the purpose for which it is. designed.

With the above and numerous. other objects in view which will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will behereinafter more fully described and claimed.

In the drawing:

embodying the featuresof my invention,

Fig. 2 is a rearelevation thereof,

Fig. 3 is an enlarged detail section taken substantially on the line 33 of Fig. 2,

Fig. 4 is anotherenlarged detail section 7 taken substantially on the line. 4-4 of Fig. 1,

Fig. 5 is a horizontal section taken substantially on the line 55 of Fig. 1, looking downwardly, and

Fig. 6 is a detail perspective of one of the plates used in the mold.

Referring to the accompanying drawing, it will be noted that I have illustrated by way of example a molding device for forming two bricks. It will be obvious, ofc-ourse, after the device is thoroughly understood, that the structure may be modified for makin one or more bricks as may be desired.

eferring in particular, now, to the example illustrated, it will be seen that 5 desig- Flgure 1 is a side elevation of the device.

nates a box-like structure or mold body preferably consisting of four walls which arepreferably arranged in a square formation.

vIn the'present example a partition 6 divides the mold body 5 into'two compartments which are preferably equal in area. The

lower ends of the walls of the compartment of the mold'body 5 and the partition '6 are [tapered so as to more easily divide the wet material such as concrete, as will be more readily appreciated as the description proceeds.

A cover ,7 is movably mounted in each compartment of the body 5 and has a block or shank portion 8 rising therefrom. As is Clearly shown in Fig. 3, the upper portion of each shank or block 8 is provided at its ends with outwardly extending tongues 9. The front and rear walls of the body 5 are notched as is indicated at 10 for receiving the tongues 9 when the covers 7 are moved downwardly for pressing the wet material in-the mold body and, therefore, the tongues9 function as stops when abutting the bottoms of the'notches 10. Angular stops 11 are affixed to the upper edges of the front and rear walls'o'f the body 5 to extend overetop of the notches for limiting the upward movement of the stop tongues 9 and therefore the upward movement of the covers 7 Bearing members 12' project upwardly from the shanks 8 for receiving the pivot pins 13 of levers 14. A pair of rods 15 project upwardly from each side wall of the mold body 5. The two pairs of rods 15 incline upwardly toward each other, and are attached to a cross head 16. The rods 15 are attached to their respective sides of the mold body 5 by suitable elements 17. A bracket 18 is fixed to each bar 15 that is disposed adjacent the rear wall of the mold body 5. The'ends of the levers 14 are pivotally engaged with the lower ends of the brackets 18 as is indicated at 19. The forward ends of the ilevers 14 converge toward each other as is indicated at 20 1n Fig. 5, attached thereto a treadle plate 21. A spring 22 is fixed to each lever 14 adjacent the portion 20 and also to the forward bars 15 as at 23. These springs normally the upper edge of the longer portion 26' there projects upwardly a pairv of ears 28... Ar pair of straps 29 is engaged with each pa r of ears28; as isindicated at. 30-. Each pair of straps. incline upwardly together toward each. other, and. havethe-i-rnpper endspivoted. one on each. side of the intermediate portion of a lever 31, the upper end of which is. pivotally engaged with. a bracket 32) dependingxfromthe cross head L6.

seen to advantage. in. Fig. 2... The lower ends ozt the levers are pivotally engaged with rods which; extend. upalongside of a handl'e 34 which rises fromthe cross head 16. A. lever 35 is. hingedly engaged as at 36 with an intermediate. portion of the handle 34;- adjacentv its upper end; and the. rods orlinks 33 are engaged to; the intermediate portion thereof as at 37. The lever- 35 limited in its movement; to. a position. at right angles tov the handle 3.4: as is clearly shown in Fig. 1, it may be swung upwardly-thru. an

' are; of approximately 90 to a position. snbstantially' parallel with the handle 84.. The

upper endv of the handle is. provided with. a

cross-head 38. V 4 y a By lifting or: swinging up the lever 35:, it

- will be seen that. the links 33 will bep'u-lled upwardly tor. raising the plates 25. These plates are preferably movable a distance:

equal to the thickness of the bricks. 7 It thought that, device has now been described with sufficient particularity so that the operation and advantages. thereof be; clearly understood- The parts are diwnsed as isx shown inv the drawing. The

workman grasps the cross head 28 and lowers the mold box 5 in the mass of wet mate-- rial such. as concrete, andfforces the mold box. dowmvardly therein so. that: the com partments 'thereoi fill with. the materia-L. and] the loweredges rest, on the floor. or bottom of the container for the material; The workman thenactuates thelevers 14. by standing or press'mg downwardly wit'lnhisz' foot the treadle plate 21,. thereby cau-singthe downward movement ofthe cover 7 to. press. the material'in the compartments .1

The workman. can then step off the treadle 21.01: release his foot therefrom, and the device is ready to be lifted from' the material and carried. to. the desired drying place. The material in thecompartment may be now released by lifting upwardly upon the lever 'vantages. The two levers 3L cross: each other as 1s I 35 so as to raise the plate 25. The device is then lifted upwardly to clear the bricks which are left behind.

The construction, operation, utility, and advantages of this invention. should now be clearly understood by' those skilled-in this art without a more detailed description thereof. The present embodiment of the invention has been disclosed in detail merely by way of example, since in actual practice it attainsthe'features of advantage enumerated asdesirable in the statement of the invention and the above description. 1 It will be apparent thatnumerous changes in the detail'sofconstruction, and. inthe combinationand arrangement of parts may be resorted. to without. departing from the .spiritor; scope of the invention as herein-;
