The diskis", provided with :i plurality of radially 'disposed mold boxes or chambers grouped in pirs, as shown clearly inFigl in which the concrete or cementis conipcteo or pressed to form the bricks. 'p l Disposed over the `'disk .is a bracket or lrzime (.lesigniitcd generally by S) that is com- 70- posed of spaced members l() providedWitlf legs 11 secured to the front portion of the" j plete .'5- and to the pivot ,(5, resp'ectively,l 'l

As shown clearly in Fig". 4,' the members 13 are spaced spart Aand A`extending horizontallyfrom one to thepther adjacent, their bottom endsis n pivot 15 o i which are links 16 that are connected Wi h Y; the operatingr levers. Fulcruineduzit 17h11 the bracket 9 is a short lever 18 that is cn", noi-ted :it its inner end by a link 19 withl 'the i hond level' 20. '.lhe levers 18 and 2() sredisvg@ posed between the members 11 of' the bracket or supportingr frame 9 and. they? ere conf"y neeted with their respective pistons bythe"- links 16, which letter carry at theiriiipper. ends itpin 21 movable in :t slot 220i' the iid-95 .im-ent lever, as shown more Aclearly in FigLA. By this arrangement, the downwardnieve# mont ol`.t.he outer end of the hand lever 2U cerises the pistons or plungers to he similiteneolisly depressed. r100 Arranged :it the `front of the machine ,and i supported on the plete 3 is ophingorbox 23 for receiving the pressing plunger of theina, chine, .find edjncont the box 23 end rmjiimtedy' on :i common bese philo 24 is i hopper or l105 filling box 25 so disposed that .it will .rcgis't with one oi" the mold clntmbcrs while in other ol" the hitter is registering Ywith the phmger box. Arrimgml :it the rear end of.; the frame ol" the machine is e stationary boxl 110 26 in. which moves the discharge plunger, the loool ion of the box being;` such that it Willreg 8 that are preferably "5 5 ister with a mold chamber 8 at the same time that the front box 23 registers with another mold chamber, so that the plungers can be `moved simultaneously, one for pressing and the `other for discharging the bricks.

' In order to rotate the mold disk 5, a lever 27 is fulcrumed at 28 so as to move about the axis of the mold disk and adjacent the outer end of the lever is a projection 29 that is adapted to be engaged in any one of the deressions 30 arranged in the mold disk 5, the ever 27 being composed of two sections connected by a hinge 31 for permitting the outer section to be raised and lowered for disengagement from and engagement with the depressions 30. By raising the lever 27 and swinging it toward the front of the machineA .so as to engage in the appropriate depression 30, the lever is swung rearwardly after its projection is engaged .in the depression for moving the disk 5 one step forwardly to form a new brick and simultaneously discharge a finished one. In the present instance, the mold boxes or chambers 8 are each provided with a partition 32, whereby two bricks can be formed in each mold box and the plungers 14 are provided with spaced blocks or weights 33, as shown in Fig. 4, to enter the compartments formed onopposite sides of the partitions 32.

The bed 1 is provided with a discharge o ening 34 located under the discharge unger box 26 for receiving the -finish'ed liricks, and arranged in the opening 34 is a pallet 35 movable vertically between rods 36 and yieldingly held in raised position by helical compression springs 37 supported on' the rods. As the discharge plunger is depressed, the finished bricks in the mold box under the same are forced out through the mold box and opening 34 to the pallet 35 that simultaneously yields with the depressing of K the discharge plunger.

separate acts being accomplished by separate operators, one attending to the manipulation of the lever 20, while the other attends to the llin of the mold chambers and the yreceivingy o the finished bricks from the pallet. After the brick under the pressing plunger has been formed, the rotary disk 5 is moved another step so that another chamber can be filled and another brick ressed. This operation is repeated until final y the pressed from the .pallet 35.

brick or bricks iiifthe first mold chamber has reached the rear of the machine and passed intoalinenient with the discharge plunger, so that simultaneously with the pressing of the bricks by the front plunger, the finished f bricks will be discharged to the pallet 35 at the rear of the machine. Thus it will be seen that the finished bricks or blocks are discharged at the same rate that they are formed and by the simple operation of the lever 20. The movementof the lever 18 is such that the discharge plunger will cause the finished bricks to pass completely out of the discharge opening 34 in the bed 1 so that the finished bricks can bc readily removed Any suitable means may be employed for holding the )allet depressed during the removal of the bricks, as will be readily understood.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and of t ie method of operation will be readily a pan ent to those skilled in the art to whic the invention appertains, and while I have de scribed the principle of operation of the in vention, together with the apparatus which I now consider to be the best embodiment thereof, I desire to have it understood that the apparatusshown is merely illustrative and that such changes may be niade when desired as are within the scope of the claims. Having thus described the invention, what I claim is z- 1. The combination of' a supporting structure, a bed thereon, a pivot on the bed, a mold disk bearing on the bed and revoluble on the pivot, pressing and discharging plungers, guides for the plungers disposed over the disk, means for supporting the guides on the structure, a mechanism for simultaneously actuating the plungers, lever mounted on the pivot and extending radially over the disk, and means on the lever for engaging the disk to turn the same.

2. In a'machine of the class described, the combination of a bed, a pivot rising therefrom, a inolddisk mounted to turn on the pivot and rest onV thebed, a frame supported on the pivot, plungers guided on the frame,

levers mounted on the frame for simultane-` ously actuating the plungers a member mounted on the pivot for oscillatory 1novement and arranged to have a ratchet engagement with the disk.

3. In a machine of the class described, the combination of supporting structure, a bed thereon, a pivot on the bed, a mold disk turning on the pivot and bearing on the bed, a frame supportedon the said structure at a 4point above the disk, pressing and discharg` ing plungers, plunger guides overhanging the disks and rigid on the structure, means on the frame engaging the members for guiding the plungers; a lever connected with one of iro the plungers and fulcrumed on the frame, an o erating lever connected with the other O p unger, and a link connecting the levers.

-, with a plurality 'of'nlold chambers, an operatl ing lever extending over the rotatable member from the center thereof to a point beyond the periphery and adapted to turn the member, said lever vbeing composed of flexibly connected sections, a stationary plunger uidqa stationary hopper, asupportin plae' or the gulde and hopper, a second p unger guideA mounted onthe said stationary support diametrically opposite from the first guide, si1nultaneously actuated plungers, and' means arranged adjacentthe second guide for receiving the bricks discharged from the mold chambers.

In testimony whereof, I affix mysignature A in presence of two Witnesses.
