Specification of Letters Patent.

Patented May 7, 1907.

Application filed August 20, 1906. Serial No. 331,228.

To all whom it may concern.-

Be-it known thatI, GEORGE MATTHEWS, a citizen of the United States, and a resident of Riga, in the county of Lenawee and State of Michigan, have invented a certain new and useful Mold Box or Pan; and I do hereby declare the following to 'be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to mold-boxes or pans for the reception and formation of semi-fluid or plastic materials into cakes, bricks, or the conjunction with peat machines for receiving the peat pulp while in a seml-fluid state and forming it into bricks preparatory to being dried, although it may be used as a mold for concrete or other plastic blocks or as a bakin pan for bread, cake, or the like.

Tn the manufacture of peat bricks it has been customary to discharge the peat pulp, which is of a consistency sufficient to prevent its running, upon boards or pallets, then cutting the cake thus formed into a plurality of sections to form bricks, of the requisite size, and placing the board or pallet with the bricks thereon away to dry. With this process the bricks dry quickly on the tops and exposed side surfaces, but retain molsture in their bottoms and centers for a considerable The object of my invention is to obviate this difficulty by the provision of a mold-box or pan having a plurality of compartments therein for the formation of bricks or blocks of the required size, which mold-box or pan is operative to release the walls thereof from the plastic or semi-fluid materialwhereby the bricks may be easily and quickly removed therefrom and-placed upon the racks to dry.

The operation and construction of one embodiment of myinvention is fully described in the following specification and shown in the accompanying drawings, in

Figure 1 is a perspective view of the moldbox or pan embodying my invention. Fig.

and loosely overlap eachother and Fig.

3 is a cross-section on the dotted line .90 a: in Fig. 1 with the mold-box shown in open p0- e sition.

Referring to the drawings, 1 1 desi nate the ends of the mold-box, 2 2 the sides t ereof, and 3 the portion of the bottom which firmly connects the two ends 1 1.

The sides 2 2 are each formed at their ends with wings 4, which lap and lie flush with the outer surfaces of the ends 1 1, as shown, and have their bottom edges, as are also the bottom edges of the sides 2 2, securely fixed to the. associated bottom portions 5 5, which are hinged at their inner edges to the contiguous edges of the bottom, portion 3, as shown at 6. Also hinged to the sides of the bottom 01'- tion 3, having a common pivot with the ottom portions 5 5, and connecting the opposite ends 1 1 are the two partitions or inner walls 7 7, which divide the box transversely into three compartments, as shown. These artitions are formed at their ends with lateral wings 8, which lie flush with the inner sur faces of the ends 1 1 and each carries a fixed pin 9 near its up or edge. These pins project outwardly free y through registering segmental slots 10 and 11 provided in the ends 1 and wings 4, respectively, contiguous to the wings 8 of said partitions, as shown. The slots 10 and 11 are so disposed relative to each other that when the box or pan is closed, as in Fig. 1, the pins 9 are positioned at the inner ends of the slots 10 and at the outer ends of the slots 11, or substantially so, said slots being of suitable length to permit a requisite opening movement of the two side com artments.

T e compartments formed by the partitions 7 7 may either be left entireor separated longitudinally into a plurality of divisions of suitable size by positioning transverse dividing walls formed of lapping wings 12 and 13 therein, as shown. To each side wall of a compartment is fixed one of these wings sulliciently to prevent a separation thereof during an o ening s own in Figs. 1 and 3.

The compartments are normally maintained in closed position by the action of the coiled contraction-springs 14, or other elastic means, one of which is placed at each end of the box and has its opposite ends fixed to lugs 15 secured to the wings 4 of the sides.

The box or pan is shown as being provided movement of the boxor pan, as

' molding it into bricks, or blocks of conven- I ends of the slots 11 to engage t e air to have free access to all sides thereof.

0 ening movement relative to each other and forces the box open to blocks and permitting .each partition 7 from the sides of the center block.

he 0 eration of my invention in connection wit a peat machine is as follows :The peat pulp, as it is discharged from the machine, is pressed within the several compartments of a mold-box ,orpan, thereby d to ave an outward movement relabeing adapted to have an outward movement relative to both the body part and partition. 3. A mold-box or pan having a body, hinged side parts, and partitionsseparatin ,the body part from the hinged arts and hinged to the former whereby to box or pan into a plurality of compartments, said hinged side parts beingadapted to be ient size. The box is then taken to the drying house and turned bottom side up upon the drying racks. The'peat blocks being. of sufficient consistency when released to retain their sha' e, the o eratorthen takes hold of the handles on t. e sides of the box and its full extent, or substantially so, thus causing the sides 2 2 and attached Wings to open outwardly from the partitions 77 and said partitions and their attached wings-too en outwardly from each other, as shown in igs. 2 and 3, thus freeing the walls of the partitions from the wet the mold-box to be lifted therefrom. When the sides 2 2 have reached their limit of outward movements relative to the partitions a continuation of the opening movement will cause the inner the associated pins 9 and move them outwardly in the slots 10, thus effecting an outward movement of 7, which disengages them ect a relative separating movement of the partitions.

4. A mold-box or pan. comprising a body, side parts hinged to the body, artitions hinged to the body and dividing t e box 01' pan transversely in a pluralityof compartments, and lapping wings fixed to the walls of the compartment thus formed whereby to divide the box or pan longitudinally into compartments, said hinged side parts being adapted to be opened outwardly from the partitions andto effect a relative spreading movement of the partitions. I

5 A mold-box or pan having a ortion of its bottom hinged to a relatively Exed portion of the bottom of the box or pan and carryingv a side wall of the box or pan, which wall'is provided at its ends with wings for lapping the end walls of the box or pan, the sa1 end walls and wings being provi ed with registering slots, a partition hinged to the fixed portion of the bottom intermediate the side walls of the box or pan, a pin projecting outwardly from each end of the partition and operating in the said registering slots, whereby an outward movement of the hinged part relativeto the fixed part of the box or pan will at a predetermined point in its movement effect an outward movement of the partition relative to the fixed part, and means for normally retaining the parts in closed position.

In testimony whereof I have hereunto signed my name to this specification in the presence of two sbscribing witnesses.

It is apparent that an opening of the moldbox or pan not only releases the walls of the com artments from the molded bricks or bloc s, thus permitting an easy withdrawal of the overturned box or pan therefrom, but also efiects a s reading of the bricks or blocks relative to eac other so that they lay spaced a art upon the drying racks, 'thus' allowing Having thus described my invention, what I claim as new and desire to secure by Let- 1. A mold-box or pan having a plurality of compartments hinged at their e ges to the ed es of a central compartment part the side wa ls of which are movable and form the inner walls of the hinged compartments, the said hinged compartments and their inner side walls being adapted to have an outward t e central compartment part.
