BRICK MOLD.

Application filed January 31, 1927. Serial no 164 851; 7

This invention relates to molds and-more particularly to a mold in which bricks, build ing blocks and the like may be formed. lVhen clay bricks are molded or cemcnt'building blocks formed. in a mold, it is sometlmes diliicult to remove the formed bricks or blocks from the mold. Therefore, one object of the inventionis to provide a mold in which a number of blocks or bricks may be formed 10 and the walls of the mold released and swung outwardly and downwardly out of engagement with the bricks or blocks so that they may becasily lifted off the bot-tom of the mold.

. Another object of the'invention is to pro vide the mold with side and end walls which may be interlocked with each other and to provide improved latches carried by the side walls and adapted to en gage-the end walls and securely but releasably retain the walls in an upright position.

-' Another object of the invention is to divide the mold intoa number of compartments by artitions removably mounted between the sidewalls of the mold, certain of the partitions being formed with side extensions; or cores which serve to provide mortar-receiving recesseslin the rear faces of bricks or building blocks formed in the mold.

Another object of the invention is to so formed therein may be securely anchoredwhen employed to form awall and prevent them from accidentally working loose and dropping out of the wall. I

The invention is illustrated in the accompanying drawings, wherein I,

Figure 1 is a top plan'view'of the mold; L Fig; 2 is a view showing the mold in side elevation; j I 40 -Fig. 3' is a longitudinal sectional view throughthe mold; v

Fig. 4 is a view showing the mold in end elevation; 1

Fig. 5 is'an' enlarged perspective view of one of the partitions forming-part ofthe mold, and I Fig; 6 is a perspective View of a building block or brickformed in the mold.

The mold in which the improved building blocks or bricks are formed is provided with v a bottom consisting of crossstrips l nailed or otherwise secured upon longitudinally extending stringersQ; The side and end walls 3' and' lare=pivotally connected with'th'ebottom by hinges 5 and 6 s'o-thatthey may be swung from-an upright position to a lowered construct the mold that the bricks or blocks inoperative position where they willvb e out of the wayjand permit bricks and building 1 blocks formed in the mold to be removed. lVithin the confines of the side and end walls the cross strips forming the bottom are covered bya metal'sheet 7 which provides a rear ice. 7 I

smoothbottom of the mold and prevents clay or cement from passing downwardly through the'spaces between the cross strips. Cleats 8 are secured against the end 'strips l to engage the outer faces of the end walls when in an upright position and brace these wa'llsin order to remove strain from the hinges'and' prevent the walls from being forced out of a vertical position by pressure from within 6 the mold. If desired, similar cleats may be provided to engage the side-walls. By referriiig to Fig. 1, it will be seen that the side walls 3 have their end portions reduced in thickness from their inner faces thereby providing tongue extensions 9 which fit into re cesseslO cut into the inneri'aces of thefend. Therefore, close fitting joints will be I walls. formed between the sicle andend walls the walls will have interlocking engagement 7 with each other, It should also be noted that the end walls have their upper faces cut to provide: recesses 11 to receive the shank portions 12 of hooks 13 formed at-the ends of resilient latch strips 14. The latch strips 1e whichextend longitudinally of the side walls 3 are secured against the outerfaces thereof by s'rews or other suitable fasteners 15 and are of such length that their end portionspro iect from the'ends' of the side walls for over y lapping engagement with projecting, end

portions ofthe end walls. At their ends the latch strips are beveled to' formcam surfaces 16' for engagement by'the: end walls so that,

when the side walls are swung upwardlytoi araised or operative positlon, the end walls may he swung upwardly and by engagement with the cam surfaces lift theendsjof" the latch strips and move into proper engagement of: the side walls fit into the seats10 tormed with the ends oftlie sidewalls. When the end walls are raised, the tongueiextensions9i in the end walls and the hooks; of the'latchi' strips engage the end walls and serve to securely but releasably retain the walls/ole: When it-- is: desired to rel-ease'the vatedi wa'llsso'th at 'E'llOYlTlfL}! beiswung downwardly to permit removal of the bricks orr building blocks' formed in the mold; the-end: portions ofthe latch strips are swungupwardly and the end walls canthen be easily swung dowmwardly into a reclining position upon the bottom. The side walls will then be released and 7 may also be swung downwardly. It will thus be seen that the walls are so formed that they may be securely held in an upright operative positionbut very easily releasedand swungdownwardly.

In order to divide the mold into a plurality of compartments, there has been provided

artitions

17 and 18 which extend'transversey'of the mold between the side walls and rest upon the sheet metal bottom. These partitions are preferably formed of wood and have their ends seated in grooves 19 formed in the inner faces of the side walls in order to properly space the partitions from each other and prevent them from moving out of proper spaced relation when in place. 7 The parti- I tions 18 are formed with flat uninterrupted side faces but the partitionsl? carry cores 20 which project transversely therefrom. These cores are formed of sheet metal and are provided with sloping side and end walls 21 and walls may 1 thereby 22 which terminate in

flanges

23 and 24 se- "cured against the side faces of the partition b Y nails or other suitable fasteners driven tlirough the flanges. By referring to Fig. 3, it will be seen that the

partitions

17 and 18 are alternately disposed in the mold and when the compartments are filled with clay or cement each brick or block 25 'formedrwill sufliciently-set to permit removal of building blocks the end walls are first released and swung downwardly and the side walls then lowered. After the walls are lowered it will be very easy to remove the bricks or blocks one at a time from the mold and then reassemble the mold.

Having thus described the invention, I

1. A brick mold comprising a bottom, side and end walls pivoted to said bottom, said end walls having their end portions overlapping the'endsof said sidewalls and projecting transversely therefrom, the projecting end portions of the end walls being formed with recesses leading from their upper edge faces, and spring strips of greater length than the side walls secured intermediate their ends against the outer faces of said side walls and having their end portions projecting longitudinallytherefrom and recessed from their under faces to provide shank portions fitting and quickly 7 into the recesses leading from the upper edge faces of the end walls and bills to engage the outer side faces of the end walls, the extreme end portions of saidstrips having their under faces beveled longitudinally to form cam surfaces.

2. A brick mold, comprising a bottom, side and end walls pivoted to said bottom, said end Walls having their end portions overlapping the endsof said sidewalls and their upper portions projecting transversely there from and formed with recesses leadin from their upper edges, said sidewalls havingtheir end portions reduced in thickness to form tongues and said end walls having their inner faces formed with grooves receiving the tongues of the side walls when-the'walls are upright, and spring strips secured against from the upper edge faces of the end. walls when the hooksare engaged with the end.
