" The object of the invention is to provide a simply constructed mold, of this chara'c'er 25* member is employed for each row-of blocks which may be quickly assembled and taken apart and the size of whieh may be extend ed indefinitely by, adding more mold inennv hers to provide for the 'moldingof 1 number of blocks simultaneous Another object is to provid molding sii'miltaneously a multipllcr ticles such as blocks or thelike' which so constructed that only one longitudinal -ms.

When strips 1, I shaped in cross section are em: ployed, a small recisron 8 is formed in'the upper faces of the blocks opposite the sides thereof to provide for the introduction of seine form'of-binder or filler but this may perspective view of .a block constructed in disposed These;

When they are embodied, small nicks 9 maybe formed in j said plates in position, owing to the fact that I the members 1 to receive the division plates 4, a very small nic'k being required to hold the pressure is evenly distributed over the whole surface of the mold structure and not against one division plate only.

The division plates l can always be used square as the small hole in the. grooved side of the longitudinal members 1 which fills with concrete-Lniaking connection on the wav down, wi not affect the block at all, as in removingth'e blocks the tongue be ing connected at 'suiih a small portion, will easily break off satisfactorily.

The end plates which are exactly alike are preferably constructed in the fornr shown in Fig.1 with lateralflanges 10 and 11 projecting outwardly from its upper and lower edges to reinforce and stiffen said pla-tes. Each plate 3 has a plurality of transversely extending longitudinally. T spaced slots 12 positioned to receive the apertured lugs 2 which project from the ends'of the strips 1, the openings in said lugs being so positioned that when a pin 13 is driven into said openings, the back plate will wedge uptight against it asis shown clearly in Fig. 4. These end plates. 3 are also preferably provided with transverselyextending bracing ribs 14 arranged at suitable intervals and secured thereto between the flanges 10 and 11 thereof as is shown clearly in Fig- 1, saidt-lreinforcing ribs. being here shown in the form of metal plates folded upon themselves interniediately of their ends and having laterally extending feet 15 which are riveted or otherwise secured to the plate-3. The ends of these plates 3 are provided with apertured lugs 01' ears .16

arranged at their upper and lower'edges which are designed to overlap when two 45' plates are employed and by means of which the plates are secured together bypassing a fastening pin 17 through said'apertured ears. 7 V

In -the form shown in Fig. 6, one ofthe longitudinal members .1 which is employed in connection with the formation of .corner blocks is shown inlwhich the longitudinal .groove terminatesat a point spaced from the end of saidplate as shown at '18;

In the form sliojv-i igiii'Fig. 5 when it is desired to produce blocks having registering posite faces, th

longitudinal grooves or recesses in their opmember 1' is employed which is provide on its opposite faces with longitudinally extending outwardly bulged members 19 so that when this form of mem- I "her, is employed both faces or side edges lfof the block will be, grooved so that wh n the blocks are assembled there a 1ongitudinally extending air space between them such as is often employed in connection with building blocks.

When setting up a mold for making a large number of blocks orother articles, the

longitudinal members. 1 are arranged on a hard floor in parallel relation and after the spacing or division plates 4 have been positioned in respect to the various members, the end plates 3 are applied by engaging the tongues or lugs 2 with the slots 12 in said end plates and by driving in the wedge pins 13 whereby said longitudinal members and division plates are securely locked in operative position ready to receive the'cement for forming the molded articles, then the concrete is poured into the molds byany suitable means not shown and is. leveled off inthe usual manner. The blocks are then allowed to set for twenty-four or thirty hours when they will be found to be sufiiciently strong to be removed and stacked up tocoinplete the setting process. It -is of course understood that to remove the-molded articles, the assembling process is reversed,

members detached, then one of'the longitudinal members is removed and the blocks confined thereby may be taken away and carried to asuitable place of deposit and. I

the nextlongitudinal member is removed and the process cont nued'until all '.of the blocks have been'removed and stacked.

Vhile Iv have described this improved I mold in connection with the formation of blocks, it is to be understood that it may be used for producing any sort. of moldedce-a ment articles.j.a'll that is necessary being to have the molds of the required shapes,- the articles being employed.
