MOLDFOR FIRE-KINDLERS.

SPECIFICATION forming part' of Letters Patent No. 237,804, dated February 15, 1881.

Application filed January 8, 1881.

To all 'whom it may concern:

Be it known that I, DAVID A. BEERY,of the city of Springeld, in the county of Clarke and State of Ohio, have invented a new and useful Improvement in Molds for Fire-Kindlers, of which the following is a specification.

My invention relates to molds for that class ot' fire-kindlers which are made of a composition of sawdust, resin, &c., which mixture is lled into the molds while in a heated state and subjected vto pressure, and when sufficiently compressed and cooled is discharged from the molds and the operation repeated, as before. y

The fire-kindler manufactured in my improved molds is made with a hole through it of the form of a star, it being easily understood by reference to the drawings.

The obj ect of my invention is to render more easy the operation of discharging-the kindlers, and also to prevent breakage and loss of the same in freeing them from the molds.

Heretofore a single following-block has been used to press down the material in the several compartments of the molding-frame, and if there is a greater or less amount in some than in others, the sections of the following-block, which enters the mold-boxes, being all rigidly attached together or comprised in a single piece, the consequence is that it often sticks in the molds, and when raised therefrom by force, as it must necessarily be, portions of the kindlers are often broken off, attaching Y such broken parts to the face of one or more of the .sections of the follower. To obviate this I make an independent follower or separate block for each kindler-mold, and as these are loosely fitted they very readily adapt their faces to any inequality in the fillings, vand after pressure is complete can be easily raised without danger of detaching any portion of the material with which the mold is filled.

Figurelis a perspective view of the moldingframe and face-board to which it is hinged. One of the following-blocks is also shown as it is placed in one of the mold-sections after the latter is filled with the composition for the kindler. Similar blocks are placed in each one of the sections of the molding-frame after they are lled ready for the press. Fig. 2 is a top view of one of the sections shown broken (No model.)

fromI the molding-frame. Fig. 3 is a bottom view of the star-shaped core-block, which eX- tends from the bottom to the top of the molding-frame. It is cast with four'iat arms or bars extending laterally from its base, by which it is attached to the under side of the frame. Each core is separately attached to the under edge of the cross-rails of the molding-frame, so that in case of one of the series becoming broken it can be easily detached and replaced by another. Fig. t is an elevation of the core and its attaching-bars. a corner section broken from the face-board. Fig. 6 is a perspective view of one of the following-blocks, showing its reverse or face side.

A is the molding-frame, within which are a series of square box-molds. Within these is seen a star-shaped block or core, ce, which eX- tends from the bottom offrame A to the top of the same. A dat thin bar, c, extends at right angles from the base of a to each ot' tlie four sides ofthe mold-box b, lapping half-way under the edge of each rail of the section, and s secured thereto by screws. As these bars are fastened upon the under edge of frame A, they necessarily project a distance equal to their thickness below it, and grooves are cut to receive them and the projecting points of the core-block (which is cast on a level with their under sides) in the face-board B, as seen in Fig. 5 at e.

The following-block O has a star-shaped hole, d, cut through that part b which enters the mold-section b, large enough to pass loosely over the core e. It has a metal face-plate, c', screwed on to protect it, and a cap, f, to gage its depth.

rIhe material is placed in the molds b around the cores a, and a following-block, C, placed in each one before being put under the press. After it has been compressed and cooled sufciently the molding-frame Ais swung up from the face-board B, (to which it is hinged,) the followers C removed and the kindlers taken out. The openings g within the mold, on each side of the bars c, allow the introduction of the ngers on the under side of the mold for that purpose.

I claim as my improvementl. In a mold for nre-kindlers, the combination, with frame A, having the elevated star- IOC shaped cores a attached thereto in its several lowing-blocks C, ns and for the purpose heremold-seetions, of the face-hoard l5, having inhet'orie set forth.
