MACHINE PRODUCING SLABS FOR BUILDING PURPOSES.

Specification of Letters Patent.
Application filed March 16, 1909. Serial No. 482L797.
England, and resident of Mitcham, in thecounty of Surrey, Kingdom of England, concrete-slab-manufacturers foreman, have invented certain new and useful Improvements in Machines for Producing Slabs for Building Purposes, of which the following is a specification.
Tlns invention relates to an lmproved machine for producing slabs from crushed clinker and Portland cement, lime, sand or other suitable material, for building partitions, garden walls and the like; the improved machine will produce slabs of great strength, homogeneous throughout, and operates more quickly and economically than has heretofore been possible.
In the accompanying drawings Figure 1 is a part-elevation, part vertical section of the improved machine for roducing slabs, Fig. 2 is a part cross section through the feed-hopper and mold, Figs. 3 to 7 show the relative position of the operative devices during the production of a slab, and Fig. 8 is a detail v1ew hereinafter referred to.
As shown, the machine comprises a mold which is mounted upon a stand or frame A of a suitable working height and which comprises two side portlons or guides a, a parallel to each other, one a of which has a slot a extending a short distance at its bottom end to allow a pallet B to be pushed in from the side, the frame A having a roller 0 to facilitate this 0 eration.
Above the si e portions a, a of the mold are secured two brackets D, D on which is pivoted a swinging front E which at a certain period of the operation is closed tight against the ends of the side portions a, a of the mold, at right angles thereto, and is locked in this position by catches preferably one on each side of the machine and arranged in the path of movement of the door, each of said catches comprising a bolt 6 (Fig. 8) guided in the frame A and adapted to be reciprocated vertically by means of ins or rollers e on said bolt being en aged ythe inclined end 6 of a rod a suitably guided in the frame A and operated by a cam or the like. When the slab F is ready for delivery the front E is swung up. (as shown at Fig. 7) to allow said slab F to be pushed out of the mold the swin ing movement being controlled by a rod on either side of the machine frame worked by cams such as H each mounted on a wheel I at the other end of the frame A; or other suitable means mi ht' be used. The swingin front E, the si'e portions a, a of the mo (1, and also the back portion of the mold have tongues and grooves on their inner faces in order to give the slabs the required shape at their edges for interlocking together when built.
Above theside portions a, a of the mold 1s a hopper J to hold and convey the material into the chamber or space left between the guides or side portions of the mold, the bottom of which mold isformed by the pallets B placed under the said side portions and supported .by rollers b. Each separate slab is made and delivered on a board B, as,
shown'in Fig. 7.
Just below the hopper J ,and sliding in grooves a (Fig. 2) 1n the side portions of the mold, is the cut-off K, which, moving backward and forward, controls the supply of material from the hopper J, and by reason of its cutting edge is bein disposed at an angle, presses the material own on to the board B. The cut-off K is shown in Fig. 3 as moved forward and preventing material in the hopper J from entering the mold. In Fig. 4 the cut-off is shown withdrawn to allow the material in the hopper J to enter the mold.
Between the sides a, a of the mold, at right angles thereto, and guided by a frame follower, is the back part of the mold forming also the ram L which at a certain part of the operation moves forward a short distance to press the material into the tongues and grooves on its front face and also on the face of the swinging front E, as shown in Fig. Sliding between these portions a, a of the mold at right angles thereto is a casting M termed the stock, into which are fixed cores or pegs we, pointed at their ends and evenly spaced along the face of the stock. When the cut-off K is closed and the back portion of the mold (the ram L) moved forward, thereby compressing and confining the material between the mold-sides, the pegs are forced through holes Z in the rear portion of the mold or ram L, and through the material (as shown inFig. 6), thuspressing it outward on all sides tightly against the mold. The swinging front E is then opened while the cores or pegs m are still in their forward posi- Patented m. 15, taro.-
tiou. The ram L then pushes the complete slab l forward together with the board B, a
- projection l on the ram engaging said board,
(Fi 1), tie said wheels being adapted to mesi with suitable reducing gear for workin at a low speed.
Vhat I claim and desire to secure by Letters Patent of the United States is 2.-
1. A machine for producing slabs for building purposes, comprising in combination, a mold, sideortions thereto, a pallet carried on a stantf or frame thereunder, a hopper above said mold, a cut-ofl' adapted to be inserted between the hopper and the mold, a stock fitted with' egs or cores for compressin r the materia within the mold, and a ram or ejecting the finished slab.
2. A machine for producing slabs for building purposes, comprising in combination, a mold, side portions thereto, a swing door in front of said mold, a allet carried on a stand or frame thereun'er, a hopper above said mold, a cut-off adapted to be inserted between the hopper and the mold, a stock fitted with pegs or cores for compressing the material within the mold, and a ram for ejecting the finished slab.
3. A machine for producing slabs for building purposes, comprising in combination, a mold, side ortions thereto, a swin door in front of said mold, a allet carrie on a stand or frame thereun er, a hopper above said mold, a cut-off ada ted to be mscrted between the hopper an the mold, a stock fitted with pegs or cores for compressing the material within the mold, and a ram for ejecting the finished slab.
4. A machine for producin slabs for building urposes, comprising m combination a mo ld, side portions thereto, a pallet formin the bottom of the mold thereunder, rollers %or supporting the said pallet, a ho per above said mold, a cut-off adapted to be inserted between the hopper and the mold, a stock fitted with pegs or cores for compressing the material within the mold, and a ram for ejecting the finished slab.
5. A machine for producin slabs for building purposes, comprising in combination, a mold, side portions thereto, a alletcarried on a stand or frame thereun er, a hopper above said mold, a cut-off adapted to be inserted between the hopper and the mold, a stock fitted with pegs or cores for colnpressin the material within the mold, and a ram or ejecting the finished slab, and means for controlling the movements of the various parts of the molding device.
In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two subscribing witnesses.
