To LZZ whom t may concern:
Be it known that I, ITHAMER E. YARNELL, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Improvement in Concrete-Building-Block Machines, of which the following is a specification.
This invention relates to a mold for manufacturing building-blocks; and the object of the invention is a mold of this kind which is adjustable, so that a large number of sizes of blocks can be made therein and also blocks of various design, the machine being adapted for use in molding both solid and hollow blocks.
Another object is a mold of this type i which the cores are adjustable with respect to the mold to accommodate blocks of various sizes.
The invention consists in the novel features of construction and combination of parts hereinafter set forth, pointed out in the claims, and shown in the accompanying drawings, in Which- Figure 1 is a perspective view of the mold ready for use. Fig. 2 is a perspective view of the mold, showing the mold in open position and a finished block thereon. Fig. 3 is a transverse vertical section, a core being shown in elevation and in its innermost position. Fig. 4 is a front elevation. Fig. 5 is a perspective view of a rear side plate. Fig. 6 is a perspective view of a front plate. Fig. 7 is a perspective view of an end plate. Fig. 8 is a perspective view of the end plate used opposite the plate shown in Fig. 7. Fig. 9 is a perspective view of a bottom plate. Fig. 10 is a perspective view of the frame supporting the mold. Figs. 11 and 12 are perspective fragmentary detail views of a bracket, core, and rack. Figs. 13 and 14 are perspective views of an inner rear side plate. Fig. 15 is a perspective view of a supplemental end plate. Figs. 16, 17, 18, and 19 are perspective views of various forms of bottom or bed plates adapted to lest on the plate shown in Fig. 9. Fig. 20 is a perspective view of one f crm of block made by the machine.
In the drawings, Arepresents an open rectangular frame supported in a horizontal position by suitable legs" or standards A and provided at its rear end corners With perforated ears A2 and carrying on its front side vertical shoes A3, having a plurality of perforations A4 formed therein in vertical alinelment. An upwardly-extendingbracket B,
shoe, each bracket having perforations B in the angled portion B2, which aline with the perforations Afof the shoes A3. The brackets are secured to the shoes by suitable bolts and i can be adjusted vertically by shifting the bolts to higher or lower perforations A4. At their upper ends the brackets B are connected'by cross-pieces B3, and below the crosspiece a shaft B4 is journaled in the-brackets B. Pinions B5 are keyed or otherwise secured to the shaft, so that they can be removed therefrom, and the shaft is squared at either end of the shaft. A rackbar B works horizontally between each pinion and the cross-bar, each rack-bar being engaged by the teeth of one of the pinions. When it is desired to operate but one bar, the pinion meshing with the other rack-bar can'be removed or slid along the shaft B1 out of mesh with the rack to remain idle. Each of these rack-bars is detachably connected to a core C, which works horizontally in the mold.
The mold roper comprises side and end walls D, E, and H and a bottom or bed plate G.
The front wall or plate D has opening D', Vthrough which the cores C Work, and at one upper corner or adjacent thereto is formed a projecting hook D2 and at the op osite corner a project' lug D3. An end p ate F is reduced in thickness along its vertical sides, as shown at F", and is rovided adjacent its front u er corner wit a hook F2 to engage the lu 3 of the front late and on the opposite si e with a finger 3. rated ears F4 are formed on the lower ,edge of this plate. I
The bed-plate G is sunken on its upper face and Toughened to mold a block with a roughdressed face finish and is provided with projecting perforated ears G3 at each end. An end ate H has at an upper corner a hook mem er H', adapted to engage and interlock with the hook D2 of the front late D. On the opposite edge the end plate H2, adapted to overlap and engage the adj acent portion of the rear plate E. Along its lower edge the late H is provided with perforated ears and the plate is also provided with threaded apertures H5, through which suitable set-screws can work.
The rear wall or plate E has opening E alining with the opening D of the front plate angled at its lower end is carried by each each end, and a handle B1 can be used on4 Depending perfohas a finger IIO D, and on its inner face a flange E2 surrounds the openings E. Along the lower edge of the plate E are depending ears perforated to aline with the ears A2 of the frame A, and a rod E5, passing through the ears A2 and E3, hinge the rear plate E to the frame A. Adjacent its lower edge and on its inner face the plate E has a longitudinal rib E4 formed thereon. The front and rear walls rest on the frame A, and the bed-plate G also rests on said frame between the plates D and E. The end plates F and H rest on and transverse to the bed-plate G, and the ears F4 aline with the ears G2 at one end of the bed-plate, and the ears H3 aline with the ears Gr2 at the opposite end ofthe bed-plate, a suitable pivot pin or pintle connecting them.
It will now be obvious that the side and end plates of the mold are readily detachable and may also be swung open, as shown in Fig. 2.
In operating the machine the parts are placed in the position shown in Fig. 1. An inner rear plate J is placed in position resting on the rib E4. This plate is longitudinally slotted, as shown at J, and on its inner face has three inwardly-curved bars J2, arranged transversely to the slot J and spanning the slot. When in place, the slot J registers with* the openings E and the bars J 2 are upon one side of said opening, the central bar J 2 being between the openings E. The machine is then iilled two-thirds full of concrete and tamped, and the cores C are then driven through the mass by rotation of the handle B7. The mold is then filled and the tam` ing operation resumed. The block is su se# quently trimmed down with an edging-tool.
In order to make various sizes and shapes of blocks, supplemental bottom and end plates are provided, which fit within the molding-frame previously described. In Fig. 15 I have shown an end plate K having a central curved ridge K stam ed thereon. When plates K are set in eac end of the mold, grooves P are formed in the. ends of a block P, as shown by the dotted lines in Fig. 20, Whereas with the plates K omitted the stone would appear as shown in full lines in said figure.
The face of the stone is formed by the bedplate G, and supplemental bed-plates may rest on this bed-plate, not only varying the size of the block 1n thickness, but also changing the face finish. In Fig. 16 I show asupplemental bed face and beveled-edge stone or lock. In Figs. 18 and 19 are shown smaller bed-plates, used with supplemental end plates, the plate C being smooth and having beveled edges and the plate O being rough-dressed and similar to the bed-plate G, except in size.
In making a block of less than the usual size but one core is required, and by moving the pinion B5 along the shaft B4, so as to throw it out of engagement with therack, only one core C is operated. Reference has been made to threaded apertures H5, through which a suitable screw can work. These are for the purpose of adjusting the su plemental end plate resting in the mold a jacent the end plate H, as will `be readily understood. In making blocks of various size it is of course necessary that the core or cores be vertically adjustable, as heretofore described. When solid blocks are made for veneering, the cores C are not employedl The machine herein described and shown in the drawings will make six sizes of blockstwo solid and four hollow.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination with a frame, a mold formed of detachable side, bed and end plates adapted to rest on the frame, means for locking the side and end ieces together and to the bed-plate, vertically-adjustable brackets carried by the frame, a shaft carried by the brackets, pinions thereon, rack-bars engaging the inions, and cores ada' ted to Werl( in the mo d and connected to t e rack-bars.
2. A machine of the kind described comprising a bed-plate, end plates hinged there'- to, front and rear plates restin on the bedplate and locked to the end p ates, alining opening in the said front and rear plates, ver-- tically-adjustable brackets in advance of the front plate, a shaft carried by the brackets, pinions slidably carried by the shaft, racks 1n enga ement with the pinions, and cores carried y the racks, as and for the purpose set forth.
