To all whom it may concern:
Be it known that I, JERvIs R. HAnBnoK, a citizen of the United States, and a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Block-Machine, of which the following is a specification.
My invention relates to machines for molding blocks of concrete and other plastic material, and the objects of my improvements are:-to provide a machine of this kind which shall be simple and easily manipulated; to provide a machine in which the weather face of the block is formed by the bottom plate of the mold; and
to provide a machine in which the molded block is carried to discharging position while still in the mold.
My invention consists in a frame, a secondary or guide frame pivotally mounted thereon and a mold slidably mounted on the secondary frame.
It further consists in novel means for controlling the movement of the mold on the secondary frame.
It also consists in novel means for opening the mold to free the molded block.
In the accompanying drawings, Figure 1 is a side view of my improved machine. Fig. 2 is a plan of the same with the operating handles removed. Fig. 3 is a view of a pallet. Fig. 4 is a view of a molded block. Fig. 5 is a side view of the machine with the mold about to be lowered. Fig. 6 is a front view of the closed mold. Fig. 7 is a rear view of the mold and core frame. Fig. 8 is a front view of the mold opened. Fig. 9 is a plan of the same. Figs. 10 and 11 are cross sections of the closed and opened mold in the lowered position.
Similar reference characters refer to like parts throughout the several views.
In the drawings, the main table or base is formed of a top 1 and legs 2. Pivoted to the top are the two handles 3 connected at their upper ends by the cross bar 4 and having slots 5. Piveted to the table at 6 is a secondary frame consisting of the side bars 7, hooks 8, cross plate 9 between the hooks, and core frame 10 to which the cores 11 are secured. The frame may be swung from the position shown in Fig. 1 to that shown in Fig. 5 at will. The side bars 7 are provided with ways or guide slots 12 in which the guide flanges 13 of the back plate 14 may freely move. These guide flanges extend well to the rear to prevent looseness. The core frame 10 has'an upwardly projecting lug 15 which is adapted to be engaged by the pivoted hook 17 on the back plate to hold the back plate adjacent to the core frame. Pins 16 project from the back plate and are adapted to slide in the slots 5 of the operating handles.
Pivoted to the back plate are the end plates 18,-
whose upper hinges have projecting fingers 19. A lever 21 is pivoted to the back plate at one side or the other of the hook 17. Links 20 and 22 connectthe fingers 19 of the end doors to the lever 21 so that the operator can open and close the doors at will.
A bottom plate 24 is pivoted on the rod 25 mounted in the frames 26 of the back plate 14. The side plates are provided with fingers 27 that are adapted to engage in holes 28 in the end edges of the bottom plate. The end plates are provided with inwardly projecting flanges 29 which are adapted to contact with the front side of the pallet 30, thus holding it in position. The pallet rests on the bottom plate which is held up by the rod 25 and the fingers 27 on the end plates. Pins 31 project from the end plates and a hooked rod 32 is adapted to engage both pins and hold the parts of the mold locked together.
The operation of the machine is as follows. The mold being closed and the rod 32 laid over the pins 31', it is filled with the block material which is well tamped to prevent air-spaces. If it is desired to form the block with a face of rich material, the mold may be moved forward away from the cores so this material may be .spread on the bottom plate, after which the mold is moved back and filled as before. After the mold has been filled, the frame is tilted to the position shown in Fig. 5. The operator then grasps the cross bar 4 with one hand and releases the catch 17. with the other, and lowers the mold to the cross plate 9 as shown in dotted lines in Fig. 5. He then removes the hook 32 and opens the end gates by means of the lever 21, the opening of the end gates releasing the bottom plate, which swings away from the block as indicated in Fig. 11. If the. bottom plate sticks to the block it may be pushed back by hand. The grooves in the ends of the blocks, as shown in Fig. 4, are formed by plates 33 secured to the end gates. The opened mold is then raised by means of the handles 3 until the hook 17 engages the lug 1.5 on the core carrier. The finished block is carried away on its pallet and the tilting frame swung back to the position shown in Fig. 1. Another pallet is put in place, the end gates closed and the locking rod 32 placed'over the pins 31. The mold is now ready to receive material for another block. While the block is being rammed the bottom plate rests on the top 1 of the machine so there is no great stress on the bolt 25 or fingers 27. The bottom plate may be of any desired pattern.
Having now explained my improvements, what I claim as my invention and desire to secure by Letters Patent is:
1. In a block machine, the combination of a base and legs for the same, a tilting frame mounted thereon, a back plate slidably mounted on the tilting frame, end plates and a bottom plate hinged to the back plate and a removable pallet forming the front of the mold and supported by end plates and bottom plate.
2. In a block machine, a tilting frame, means to support the same, said frame comprising side bars, a core carrier and a cross plate, cores mounted on the core carrier, a back plate slidably mounted on the side bars and having apertures for the cores, end plates and a bottom plate hinged to the back plate, and a pallet forming the front of the mold, the parts being so mounted that the mold when closed may be moved against the core carrier and there filled, the frame then tilted to vertical position and the mold slid down until the pallet rests on the cross plate, the mold then opened to release the pallet with the molded block thereon, and the mold and frame swung back to original position.
In a block machine, the combination of a base, a tilting frame mounted thereon, a mold formed of hinged parts, which mold rests on the frame when being fi led, and means to carry the mold down to discharging position and up to loading position along the tilting guide frame.
4. In a block machine, the combination of a base, a nor mally horizontal tilting frame mounted thereon, a back plate slidably mounted on the tilting frame, end plates, a bottom plate, and a removable pallet forming the front of the mold, and means to secure the parts of the mold to gether.
5. In a block lnaehine, the combination of a base, a normally horizontal frame mounted thereon and adapted to be swung to vertical position, and a mold mounted on said frame, one of the sides of the mold being vertical when the mold is being filled and adapted to be swungdown to horizontal position, the remainder of the mold being adapted to be moved away from said side to permit the lllOldOd block to be removed from the machine.
(3. In a block machine, the combination of a, base. a frame mounted thereon and adapted to be swung from horizontal to vertical position, and a mold mounted on said frame and adapted to rest at one end of the same when the frame is in horizontal position, and to slide to the other end of the same when the frame is in vertical position.
7. I11 :1 block machine, the combination of a base, a tiltable frame mounted thereon, and a mold formed of hinged sections adapted to move along said tiltable frame. one of the sections being slidably mounted on the frame.
In testimony whereof I have signed this application in the presence of two subscribing witnesses.
