- provision of a device of this character conline x-:c of Fig. 3 looking'toward .the rock` structed in such manner that `blocks of varying sizes and shapes maybe readily molded therein.
Further objects and advantages ofthe in'` vention will be set forth in the-.detailed der scription which now follows.;
In the accompanyingdrawings: Figure 1` is a side elevation of aconcrete blockmachine constructed in accordance withy the inventlon, Fig. 2 1s a centralvertical section upon shaft, Fig. 3 is an end` elevation of-thamachine, Fig. 4 is a lan viewof1the machine with the pallet of t e mold boxomitted, F ig. 5 is a detail sectional View of therear side of the mold box, Fig. 6 is a horizontal section. upon line a-a `of Fig. 2, and, Fig. 7- is a de tail view of a modified form of mold box.
Like numerals designate correspondingk parts in all of theligures ofthe drawings.
Referring to the drawings, the numerals 5 and 6 designate standards whichserve to support a top plate 7-,said top plate and said standard forming the frame vof theumachine."
sequently the throw of the cross-head 10 mayy be regulated. The lower ends of the links 13 are connected to the ends of levers 15. These levers 15 are mounted upon `a rock shaft 16, to which movement may be imparted .by a handle 17. The plate 7 has a plurality of perforations 18 and a plurality of slots 19 ormed therein for a pur ose Which will be hereinafter set forth. T e mold box cornprises a rear wall 20 from which perforated lugs 21 extend, end walls 22 and a front wall 23. The end Walls 22 'are pivoted to the rear Wall 20 at 24, while the front wall 23 ispivotedtoone of the yend Walls -22 at 25. At its opposite end the front wall 23 is provided with a notch 26 which receives a tenon 27 of .the other end wall 22.
A bolt 28 is pivoted -by `apin l291 between lugs 30 carried by one of the end walls-22. A nut 31 is threaded upon the outer end of this bolt and is provided vwith a handle 32 by-which it may be rotated.y
The form-of the mold box illustrated in Fig. 7, is the same as that illustrated in the `other `figures of the drawing and the same reference numerals have been applied to like parts therein.
Stop `lugs 33-and 34 are carried upon one v end ofthe plate 7 and serve a purpose which will be hereinafter set forth. When the sides ofthemold box are closed, a bottom for the mold .box is formed by a pallet 35, said pallet `having openings 36 formed therethrough for the passage ofthe cores 12.
1 The; .operation ofthe device is as follows: The mold box is secured in position upon the plate 7 by bolts 38 which pass through the openings 18 and are threaded into the lugs 21. It is by these means that the rear wall 20 of themold box is secured in position, the end walls. and the front wall being supported from this rear wall by means of the hinges 24 `and 25. When. the walls are swung back into -the positiony illustrated in Fig. 4, the bolt 28 is l.swung into such position that it lies in a slot 39 formedin a lug 40 which is carried by the end of the front wall 23. The nut 31 is `then rotatedtodraw all of the parts together, A.thisrotation of the nut A31 squaring or truing up the mold box. The handle 17 is then pulled over until it engages behind the lug 33 (see Fig. 2). This rocks the shaft 16 and throws the levers 15 to the full line position illustrated in Fig. 3. This movement of the levers 15 through the links 13 elevates the cross-head 10 and consequently lifts the cores 12 until they project into the mold box,
`the tops of said cores when the lever lies in the position just described, lying substantially level with the top of the mold box. 'After the material of which the block is formed, has been tamped around the cores, the handle 17 is disengaged from behind the lug 33 and thrown toward the left in, Fig. 3. This withdraws the cores from the mold box after which the nut 31 may be loosened and the front and end walls swung away from the oldedblocks as illustrated in dotted lines in An adjustable supporting plate 41 is car- .is rendered adjustable by being slotted for the reception of screws 42which p ass through said slots and are threaded into the plate 7.
By referring to Fig. 2, it will be seen that the cores 12 are provided upon their lower faces with tenons 43 which enter recesses 44 of the cross-head. These cores are therefore removably mounted upon vthe cross-head and may be readily removed and others substituted therefor when desired.
It is sometimes desirable to mold blocks of but half the usual height. When it is desired to do this, a mold box of the proper height is substituted by removing the bolts 38 and placing the new box in position. Cores of substantially half the height of the cores 12 are then substituted for said cores and the handle 17 is thrown over to the position illustrated in Fig. 3. This elevates the cores as hereinbefore described. When it is desired to lower these half cores, however, the handle 17 when shoved over to the left in Fig. 3, is only moved over until it engages the lug 34 instead of being permitted to move over past said lug as in the previous case.
When it is desired to mold porch column blocks, the mold shown in Fig. 7 is substituted for that shown in Fig. 4, the series of perforations 18 formed in the plate 7 readily allowing this to be done. These perforations are spaced given distances apart. For instanceI the spaces between certain of the holes are one inch apart; between other rows of holes the distance is two inches. By thus arranging these perforations it is possible by selecting a mold box which will extend between given rows of holes, to determine the size of the block to be molded without measuring. The slots 19 permit hooks to be inw seen that the machine herein shown and def scribed, is adapted to mold concrete blocks of any desired size or shape by merely substituting the proper sized and shaped mold box and pallets. j
Vhile the elements shown and described are well adapted to serve the purposes for which they are intended, it is tov be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.
. What I claim, is:
In a machine of the character described, the combination with a supporting frame, of a rock shaft journaled in said frame, a vertically movable cross-head mounted in ways formed in said frame, arms rigidly secured to the rock shaft, turn-buckle connections between the outer ends of said arms and the cross-head, removable cores carried by the cross-head, a removable mold box supported upon the frame, one of the walls of said mold box being hinged to and sup )orted by the first named walls, and a mem er longitudinally adjustable with relation to the frame and carried by said frame, said member having an upturned projection 41 adapted to limit the swinging movement of the front wall of said mold box.
In testimony whereof I aflix my signature in presence of two witnesses.
WILLIAM I-I` PHILLIPS.
