.Application led August 17, 1904. Renewed Mayvl, 1905. I Serial No. 263.157.

To all whom if; may concern:

Be it known that I, PERRY B. MILES, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Michigan, have invented new and useful Improvements in Block-Molds, of which the following various plates of the mold in position and for withdrawing said plates after the molding operation. T he construction is also advantageous with respect to the placing and removal of the core.

The invention is illustrated in the accompanying drawings, in whichj Figure 1 is a perspective view,-parts being broken away, showing the mold in position to be filled. Fig. 2 is a perspective view of the mold turned on its side and closed. Fig. 3 is a perspective view of the empty mold opened, showing the position -of the parts at the time of the removal .of the block. Fig. 4 is an end view of the machine. Fig. 5 is adetail in elevation, showing the clips which hold the face or design plate in position. Fig. 6 is a detail in end elevation of one of the clips.

The mold forming the subject of' this invention is adapted in operation to be filled in one position, and after the block shall haveset to be turned on the side to permit the convenient withdrawal of the core from the block and the block from the mold, being in this respect similar to the mold for which I have obtained Letters Patent N o. 738,830, dated September'15, 1903. In addition-to v this function the present invention includes means lwhereby the side plates ofthe mold are in part automatically Withdrawn from lcontact with the block when the mold is opened. The construction whereby this result is eected will be more apparent from the following description.

Referring specifically to the drawings, 6 indicates the ends of the machine, which have at diagonally opposite corners feet 7, upon which the mold rests in its respective positions. At the intermediate corners are rockers 8, upon which the mold may be turned to tilt the same, this construction being'essentially similar to that described in my former patent, above mentioned.

Specification of Letters Patent.

Patented Aug. 1, 1905.

Tt fatiiitt'tte the tilting of the machine, it

brackets being effected by sockets on the ends, as at 10. These brackets raise the device from the floor and allow it to swing easily to either position. 11

The outer part orframe of the mold is formed ofthe ends 6, above referred to, side bars 11, bottom bars 12, )and a hinged side plate 13. The

bars

11 and 12 extend between the ends of the frame, and the-side 13 is pivoted at 14 at one corner of the end plates. Within the frame thus formed the movable or adjustable parts are supported. These comprise a pallet or bottom part 15, a design or face plate 16, adjustable end plates V17, and a side plate 18, which is fixed to and carried by the hinged plate 13. The pallet '15 rests upon-and is su ported bythe bars 1 1.

The design-plate 16, W ich forms the face of the block, is supported upon the bars A12 by means of clips 19, which are adjustable along the bars 12, according to the size of the block to be molded, or, which amounts to the same thing, according to the size of the face-plate used. The details of these clips are shown in Figs. 5 and 6. Each consists of an upper casting 19a anda lower casting-19h, connected by a screw 190, by means whereof the barsl 12 are clamped betweenV the ends of the piece 19a and 19b and the clip positioned along the bars atany desired place. A keeper 19d, secured by slot-and-bolt connection 19e to the casting 19a, may be manipulated to engage over the top of the plate 16 at the ends thereof and holdthe same in place.

The bars 12'are connected by cross-pieces 12a at the ends thereof and are supported by hangers 20. Each hanger has two arms or branches which terminate" in laterally-projecting lugs'21, which fit in any one of the series of notches 22 in bars 23. These bars are pivotally connected at the ends by links 24, forming flexible substantially rectangular frames.. One of the bars 23, being the one adjacent the side or bottomplate 11, is fastened to the end plates 6 by bolts, as indicated at 23a. The remaining bars 23 and the links 24 are movable with respect tothe outer end frames 6, being capable of a limited sliding movement back and forth when' the mold is tilted on its side, this movement being permitted by the pivotal connection between the bars 23 and thelinks 24, as above stated.

The end plates 17 are adjustable to make longer or shorter blocks between the pallet 15 and the plate 18. The said end plates 17 are properly curved to give the desired shape to the end of the blocks and are supported in position by means of brackets consisting of slotted bars 25, which are bolted at one end, as at 26, to fixtures on' the back of the end plate 17 ,v and are secured in position by thumb-screws 27, which extend through the slots and into the end plates 6.

One branch of each bar 23 has a cam projection or finger 28, which extends through an opening 29 in the hinged side or plate 13, and the shape of this cam effects the automatic withdrawal of the design-plate 16 from the face of the block when the side or plate 18 is lifted or opened. Handles 30 are attached to said plate to effect this action and also to assist in tilting the mold. Hooks 31, which engage over projections 32 at the ends of the plate 13, serve to hold the mold closed.

The construction will be further understood from the following description of the operation. When a block is to be cast, the mold is placed in the position shown in Fig. 1, the face-plate 16 being at the bottom of the mold, the pallet 15 and plate 18 being at opposite sides, and the end plates 17 being therebetween. The facing material of the block is then poured into the bottom of the mold. This, it may be said, enables the operator to use a richer mixture for the facing and a coarser and cheaper mixture for the rest of the block. After the facing is put in upon the face-plate 16 the core, such as indicated at 33, if one be used, is then laid sidewise upon the material. It is perhaps needless to say that the core used fits snugly between the pallet 15 and plate 18. Vhen the core is in place, the remainder of the cement is placed in the mold. The mold is then tilted upon its side to the position shown in Fig. 2, which brings the pallet 15 at the bottom and the hinged side 13 at the top, as shown in Fig. 2. The hooks 31 are then disengaged and the side 13 is opened, as indicated in Fig. 3. The shape of the cams 28 is such that when the hinged side 13 is swung open, as in Fig. 3, the contact of the cams against the ends of the openings 29 is such as to slide the upper bars 23 rearwardly, as shown in Fig. 3, which action is permitted by the pivotal connection between said bars and the links 24. rlhe effect of this action is to swing the hangers 2O backward, and with them the bars 12 and the face-plate 16 supported thereon. This disengages the face-plate from the block, which is supported upon the pallet 15. The thumb-screws 27 are then loosened, permitting the withdrawal of the end plates 17. The core may then be lifted out and the block taken from the machine on the pallet. The machine may then be tilted back to original position, another pallet substituted, and the operation repeated. When the cover or side 13 closed. the Contact of the cams in the openings 29 automatically restores the face-plate 16 to its original position by appropriate movement of the upper bars 23.

As will be seen, the parts of the mold are adjustable to produce blocks ol' various sizes. rlhe tilting action whereby the mold is laced down when the material is put in allows a, block to be made with a facing of superior quality, as above described, and by turning the mold on its side after it is illed the core may be removed vertically, even before the block is fully set` without danger of collapse of the block. The lugs 2l of the hangers 2() may be htted in any one of the pairs of notches 22 in the bars 23, thereby varying the depth of the lnold. By means of the slotted bars 25 and the tlmmb-serews 27 the, position of the end plates 17, and consequently the length of the block, may beI varied as desired, and the clips l?) are adjustable along the bars l2, permitting a faceplate 16 of any desired length. to be used.
