MOLD.

To all whom it may concern."

Be it known" that I, HENRY F. JOHNSON, a citizen of the United States, residing at Morgantown, in the County of Monongalia and State of West Virgina, have invented a new and useful Mold, of which the following is a specification.

The device forming the this application is a mold structure adapted to form a plurality of solid blocks of the sort commonly used in the making of a double wall, the structure being adapted for use primarily in connection with the slushing process, as distinguished from the tamping process.

The invention aims to provide a mold so constructed that the finished product may be removed readily therefrom when the mold is inverted.

Another object of the invention is to provide novel means for interlocking the ends of the mold sections and for mounting the partitions between the ends of the mold sections, so that the partitions will constitute means for supporting the mold sections.

It is within the scope of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

IVith the above and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of What is claimed, Without departing from the spirit of the invention.

In the accompanying drawing: Figure 1 shows the invention in top plan; Fig. 2 is a side elevation; Fig. 3 is a fragmental longitudinal section on the line 33 of Fig. 2; Fig. 4 is a transverse section on the line l4 of Fig. 2; Fig. 5 is a fragmental perspective showing a portion of one end of one section; Fig. 6 is a fragmental perspective showing the other end of the section. Fig. 7 is a fragmental end elevation showing one of the end plates in place.

The present invention embodies end sections 1 and any desired number of intermediate sections 2, but three sections being shown in order to simplify the drawings, although obviously, the molding structure herein described may comprise any desired Specification of Letters Patent.

number of sections and may be of any length. Each of the sections preferably is a trough-shaped metal structure comprising a bottom 3 and resilient sides 4 which may be sprung apart. The longitudinal edges of the sides 4 are turned outwardly to form beads 5. At one end of each section, the beads 5 hold projecting fingers 6 and at the other end of each section, the beads 5 are open to form sockets 7 adapted to receive the fingers 6 of an adjoining section, all of the sections being alike.

The invention comprises a plurality of metallic partitions or end plates, denoted by the numeral 8, each end plate 8 being provided with notches 9 which receive the fingers 6. Along their longitudinal edges, the end plates are bent upon themselves to form reinforcing flanges 10.

In practical operation, the fingers 6 at one end of each section are received in the sockets 7 on the end of an adjoining section, thus holding the several sections alined. The partitions are interposed between the ends of the sections, the fingers 6 being received in the notches 9. The several sections thus are upheld by the partitions, it being noted at this point that, as shown at 15, the partitions 8 extend downwardly below the bottoms 3 of the sections.

It is to be observed that the molding structure hereinbefore described may be set up readily and with equal facility be taken down. When the product has set sufliciently, the end walls or partitions are removed, and the several sections are disconnected the fingers 6 being withdrawn from the sockets 7. The sections are then inverted and the sides 4 thereof are sprung apart manually, thus separating each mold section from its contained product.

Having thus described the invention, what is claimed is 1. In a mold of the class described, a pair of trough-shaped sections, one of which is terminally provided with sockets, the other of which is terminally provided with fingers received in the sockets; and a partition between the sections, the partition having notches receiving the fingers.

2. In a mold of the class described, a pair of trough-shaped sections, one of which is provided with sockets, the other of which is provided with fingers adapted to be received in the sockets; and a partition between the sections, the partition being provided with notches Which recei-ve'thefingers, f and being provided along its upright edges with reinforcements Which engage the sockets.

3. In a mold of the class described, a pair -f of trough-shaped sections, one of XVlllffh'dS provided'with sockets, the otherofwhieh is provided with fingers received in. the

sockets; and a partition lo'cated betweenthe sections, the fingers engaging the partition to uphold the sections,- and the"partition bei in the presence of two Witnesses,
