Specification of Letters Patent. I Patanited Apr. 26, 1921.

Application filed November 27, 1920. Serial No. 426,832.

I! '0 all whom it may concern Be it known that T, ANroNY on CICILIANI, a citizen of Jugoslavia, residing at Los Angeles, in the county of Los .Angeles and State of California, have invented a new and useful Concrete-Block-Making Machine, of which the following is a specification.

This invention relates to devices for making concrete blocks.

Une of the objects of this invention is to provide a machine in which concrete blocks of various sizes can be made.

Another object is to provide a machine in which a variety of cores can be used without material changes of the machine.

Another object is to provide a machine in which one lever actuates the several doors and cores from a fully closed position to a fully open position, and from a fully open to a fully closed position, so that, on setting the lever for the closed position, the doors and cores are firmly held in position to receive the concrete, while, on setting the lever for the open position, all the doors and cores are suitably moved away from the finished concrete block that the block may easily be removed from the device.

Other objects will appear from the following description and appended claims as well as from the accompanying drawing, in wh1ch Figure 1 1s a perspective view of the complete device in closed position, read to receive the concrete.

Fig. 2 is a detail end elevation of the front door with the operating lever attached and in operating position.

Fig. 8 is a top plan view of one of the side doors with a portion of the connecting and operating rod connected.

Fig. 4 is a detail fragmentary end elevation of the guiding members of the cores.

Fig. 5 is a detail side elevation of a core attached to the guiding member.

The base frame 6 supports the whole device and forms the stationary member, The rear body plate 7 is preferably firmly secured to the base frame. The side doors 8 and 9 are hingedly engaged with the rear plate 7, as indicated at 10. The shaft 11 1S turnably mounted on the front side of the base frame. The front door 12 is provided with lugs 13 securely pinned to the shaft 11,

as'indicated atjle. A shaft 15 is turnably mounted near the upper edge on the front door 12. The operating lever 16 and the hook and closing or looking lever or bar 1' are securely pinned to the shaft 15, as indicated at 18.

Operating the operating lever 16 produces a turning of the shaft 15 and thereby an unlocking or operating movement of the locking bar 17.

Moving or operating the front door produces a turning ofthe shaft 11.

The operating lever 16 is provided with an extension end 19. This end is provided with a perforation or hole .20, and. near the hole 20, a chain or other similar flexible member 21 is provided for holding a pin 22.

In operating this device, the operating lever is moved upwardlyso as to bring the extension end 19 in alinement with the end of the door 12, as illustrated in Fig. 2, the pin 22 being inserted through the hole 20 in the end 19into the hole 23 of the door 12 so that the lever'16 projects rigidly in the direction along the edge of the end of the door. The lever .16 engages through the shaft 15 and through the pin 22 rigidly with the door so as to form a suitably long lever on the shaft 11 for operating the shaft 11.

When the lever 16 is so operated, the door I 12 is swung open or closed,'depending on how the lever is moved. .The front end 24: of the lever 16 forms the handle of the device.

A lever 25 is securely pinned to the shaft 11 as indicated at 26. A connecting rod 27 connects with the lever 28. The lever 28 is securely pinned to theshaft 29 as indicated at 30. Movementof the shaft 11 is transmitted through the lever 25 and through the connecting rod 27 to the lever 28 and thereby to the shaft 29. A lever 81 is securely pinned to the opposite end of the shaft 29 as indicated at 32.

The levers 28 and 31 connect through 0011- Such plates or pallets are indicated at 34, 35, 36 and 37, and they are normally secured to the doors and stationary plates of the device so as to move with the doors.

A core member 38 is illustrated in the drawing, but it will easily be understood that any number of such'cores can be used for making hollow blocks. I prefer to have these cores disposed in a horizontal plane so as to bring the face of the block in the bottom or in the top surface, allowing the face to settle. These cores are shiftable to be disposed. in the device before the concrete is poured into the device, and to be withdrawn from the device before the finished block is removed from the device.

The outer walls, made up of the rear stationary plate 7, the side doors 8 and 9., and the front door 12 are provided for the purpose of holding the sides firmly together, and therefore are not required to be particularly tight (air-tight, water-tight, etc), but the inner plates 34, 35, 36 and 37 are closely fitted to prevent leakages when the concrete is poured into the device. The plate 34 on the front door 12 and the plate 37 on the rear plate 7 are therefore provided with openings 39 snugly fitting around the core 38 just loose enough to allow a shifting of the core in the manner described above. The core 38 is preferably secured to a guide member 40 for holding the core in the horizontal plane after the front end leaves the front face plate and for more steadily and evenly operating the core in the shifting movements. To

make the sliding and shifting movements quite easy and to overcome friction of sliding members, rollers 41 are provided on the guiding frame or member 40, see Figs.

4 and 5. Bracing and supporting arms 43' are provided, having a channeled face 42 for guiding the rollers 41 in their horizontal shifting movements.

g The connecting rod 44 connects the guiding member 40 with the lever 45. The lever 45 is securely pinned to the shaft 29, as indicated at 46, so that the movement of the operating lever 16, which has so far been traced and explained above up to the shaft 29, is also transmitted to the core 38.

The operating lever 16 controls in this manner all the movements of all the doors and all cores, so that, by a forward and closing movement of the lever 16, all doors are closed and the cores (depending on how many cores are required for certain blocks as explained above) are all securely disposed within the device, making the whole device ready to receive the concrete; while, by a rearward and opening'movement of the lever 16, all doors and cores are moved so as to free the finished block so that the finished block may easilybe removed from the device.
