To (gr/l7 whom, it In/(Ly concern:

Be it known that we, I-IIGNRY (iu'rrunlnoa and JOHN HENRY MoCoNNeLL, subjects of the King of Great Britain, residing at Hamiota, county of Shoal Lake, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Machines for Forming Building-Blocks; and we do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in apparatus designed especially for molding and pressing building-blocks, and is particularly applicable to the manufacture of that class of lire-proof blocks having centrally arranged apertures therein, which blocks are formed from concrete and similar material.

The object of the invention is to produce a device of the character described which will be comparatively simple in construction and easy of operation and which will so combine the cooperative parts as to produce a structure which may be operated with a minimum expenditure of power, all as hereinafter more fully described, and specifically pointed out in the claims.

In the annexed drawings similar characters of reference indicate corresponding parts in all the views, in which Figure 1 is a side elevational view of our improved apparatus. Fig. 2 is a plan view thereof. Fig. 3 is a side elevational view looking in the direction of the arrow P of Fig. 2. Fig. 4 is a longitudinal vertical section taken approximately centrally of Fig. 2.

Fig. 5 is a view, partly in section, on line 5 5 plates 2 2 resting thereon, which plates support track-rails 3, upon which track-rails are su 'iported a slidable table comprisiz'lg the runners a and supporting-plate 5, upon which plate is adapted to be carried a matrix or matrices (IQDI'OSGUtBd generally by the reference-letters A l3.) Connected with the tableplate 5 are core-supporting plates '7, which plates carry one or more vertically-1)rojectiug cores 8, which cores are adapted to form the central orilices in the linished l)UllLilllg-l)l()l(, within the interior thereof, and the end semicores 9, which are adapted to form recesses in the ends of the linished building-block, which recesses when placed in juxtaposition to cm'responding recesses in the next adjacent blocks will form openings corresponding to the larger openings within a single block. This core-rdateis supported in position by means of screw-threaded staffs to, which project through the table-plate and engage with the core-plate, the nuts 11 being used to secure such staffs to the core-plates, while screwthread ed seats 12 are connected with the tableplate, through which such screw threaded staffs are projected, so that when the wheels 13 of the staffs are rotatated it will be evident that the core-plates 7 with the cores 8 and 9 thereon are raised or lowered according to the direction of rotatation of such end wheels. As will be noted in the drawings, a plurality of core-plates 7 are carried by the table-plan 5, one being arranged approximately at each end thereof, so as to permit the'lilling of the matrix placed about one set of cores while the contents of the other matrix are being pressed by the press hereinafter described. For the purpose of forming the matrix side plates I l are provided, which rest upon the table-plate 5, the side plates M being of such proportions with relation to the tableplate as to leave a shoulder or seat 15 therebetween comprising a part of the table-plate, upon which may rest a perforated bottom plate 16, forming the portion of the matrix upon which the concrete or other material to be pressed may be placed. End plates lb are interposed between the side plates l2l-., and an auxiliary frame 17 is placed upon the upper edges of the side plates and end plates, so as to provide a temporary auxiliary matrixframe for the support of the surplus material which will be subsequently pressed into the matrix proper. W hen the matrix-frame is assembled, the yokes 18, which are pivotally connected to the table-plate 5, as shown in Figs. 3 and 5, are locked in position, so as to hold the several parts of the matrix firmly united, such yokes being pivoted upon the set-screws 19, which are adapted to project into the tableplate,as shown in Fig. 7, whereby a locking-clamp is provided which secures the matrix, including its bottom plate 16, properly in position upon the table-plate 5. A description of one matrix and its appurtenant parts will answer for both, as they are to all intents and purposes constructed in the same manner. The table thus provided is slidable upon the rails 3, and for the purpose of projecting the table longitudinally of the bedframe short shafts are projected through thebed-frarfie, as best shown in Fig. 5, upon which shafts are provided bevel- gears 21 and 22, respectively, which mesh with corresponding bevel- gears 23 and 24. upon the shaft 25. Upon the shaft 25 is a driving-pulley 26,about which extends a belt 27, running to the pulley 28 upon the main driving-shaft 29, which latter shaft is supported within an upright frame hereinafter referred to. The driving-shaft 29 being constantly rotated, it is evident that the gears 21 and 22 should be normally out of engagement with the gears 23 and 24; but when it is intended to cause the matrix-table to travel either of the levers 30 or 31 is thrown so as to bring one pair of the gears 21 to 2 k into engagement. \Vhen either pair of such gears is in engagement, its corresponding shaft 20 will be rotated, whereupon the chains 32 and 33 will be affected. Such chains 32 and 33 extend, respective] y, to the matrix-frames A B, and it will be understood that the bedframe is sufficiently long so that the table 5 may be carried, and with it such matrixframes A B will be carried, to a position where either such matrix frames will be brought into coincidence with the pressing means.

Carried by the bed-frame is an upright frame, which, as shown, is supported by means of the four upright columns or standards 35, which columns are braced by the inclined braces 36 and carry the transversely-extending connecting-beams 37 and cross-beams 38. Mounted upon the uprights are bearings 39, in which is carried the main driving-shaft 29, upon which is the driving-pulley 40, actuated by the belt 41 from any suitable source of power. On the opposite end of the shaft 29 is carried the pulley 42, from which the I crank-shaft pulley 4:3 is driven by a suitable belt 44, a belt-tightening means comprising the pivoted arm 45, link 46, lever 47, and loose pulley 4E8, cooperating with the belt &4 to

idly with the plunger-head 53.

tighten such belt when desired to cause r0- tation of the pulley 43, and thereby actuate the crank-shaft 48, the lever 47 being pivotally connected with the bracket 49, as shown. Carried by the crank-shaft T8 are hangers 50, to which are pivotally connected the reciprocatory rods 51, which rods terminate within the yokes 52, which yokes are connected rig- Upon the plunger-rods 51 are collars or enlargements 54:, and seated between the collars 5a and the horizontal upper end of the yokes 52 are compression-springs 55, adapted to receive the thrust of the plunger-rods and in turn communicate such pressure to the plunger-head 53, supplemental springs 56 being interposed between the lower end of the rods 51 and the bridges 57, connected with such plungerheads, whereby a multiplicity of resilient cushioning means are provided between such plungerhead and the source of power actuating the same. It will be understood that the plunger-head is perforated, such perforations being of a contour to correspond with the contour of the cores and semicores 8 and 9, so

that when the matrices A and B are filled and r by means of the chains 33 carried to position beneath such plunger-head the plunger-rod may descend into the matrix which is in line therewith, and thereby press the material within the matrix to the limit of compression possible with the power available. By interposing the cushioning-springs referred to between the plunger-rods and the plunger-heads it will be evident that a tamping effect may be produced by reciprocating the plunger while a matrix is in position below the same, and the most perfect compression of the concrete mixture Within the matrix is thereby produced.

\Vhile but one form of matrix is illustrated as an incident to the construction of the machine, it will be evident that matrices of various shapes may be used, either rectangular or of any other desired form, and cores of any desired conformation may be used in conjunction with such matrices upon substituting plunger-heads of the corresponding shape without in any manner changing any of the essential features of the machine, and the matrix illustrated in connection herewith is shown merely as a matter of illustration to exemplify the operation of the machine.

The operation of the machine is as follows,

reference being had to Fig. 1: The matrix A is in position for filling and may be filled up to the level of the auxiliary frame, after which the proper lever is thrown, so as to actuate the proper shaft 20, thereby winding the proper chain upon its shaft and carrying the matrix A into position beneath the plungerhead. This will cause the table to travel in the direction indicated by the arrow in Fig. 1, carrying the matrix B to the right and the matrix A beneath the compression-plunger,

whereupon the plungers may be actuated, and while the material in the matrix A is being tamped the matrix B may be filled with concrete, after which the other lever is thrown, so as to cause the table to travel in the opposite direction, whereupon the yoke 18 is released, the matrix-frame separated, and the pressed block removed from the matrix A upon the bottom plate 16, upon which it may rest until the concrete has thoroughly set. In the meantime the matrix-frame may be re assembled, a new bottom plate substituted for the plate 16, the cores and semicores again raised to position, after which the matrix may be filled and the table caused to travel in the direction to bring it under the compression means for pressing the renewed supply of ma terial.

W hile we have shown in the accompanying drawings the preferred form of our invention, it will be understood that we do not limit ourselves to the precise form shown, for many of the details may be changed in form or position without affecting the operativeness or utility of our invention, and we therefore reserve the right to make all such modifications as are included within the scope of the following claims or of mechanical equivalents to the structures set forth.
