SEBASTIAN G. BRINKMAN, OF FORDS, NEW JERSEY, ASSIGNOR 0F ONE-HALF TO LE ROY H. MINTON, OF ME'IUCHEN, NEW JERSEY.
ELECTRICALLY-HEATED PRESS FOR OLAYWARE.
Specification of Letters Patent.
Patented Dec. 4, 1917.
Application filed September 6, 1917. Serial No. 189,916.
To all whom it may concern Be it known that I, SnnAs'rIAN G. Brink- MAN, a citizen of the United States, and a resident of Fords, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Electi'ically-I-"Ieated Presses for Clayware, of which the following is a specification.
This invention relates to a press of novel construction for forming various articles of clay ware, such as dry pressed bricks, fire bricks, sand-limc bricks, silica bricks, floor tiles, for repressing plastic pressed brick, etc. The invention relates more particularly to novel and efiicient means for heating the press electrically in such a manner that the heat is confined essentially to the sole of the die or plunger, while the main body of the die remains unheated, the location of the heating element being such, that it is readily accessible for the purposes of inspection and repair.
The accompanying drawing represents by way of example, a machine embodying my invention, for pressing dry -pressed brick.
Figure 1 is a vertical longitudinal section of the brick press;
Fig. 2, a front view of the upper plunger, and
Fig. 3, a horizontal section on line 3-3,
The mold box 1 of the press, is shown to be steel lined as at 2, and to be supported at a distance above the flooring by suitable means, (not shown). Box 1 is open on top and bottom for the accommodation of the upper and lower plungers 3, which are simi lar in construction, though they are, of course, opposed to each other. The plungers 3 may be operated by suitable means, preferably electric, which means however, do not form part of the present invention. As shown, each plunger consists of a matrix 4, secured to a head 5 by bolts 6, the matrix being made of metal and being cut out as at 7 for the purpose of reducing its weight. To the operative face of each plunger, there is removably secured, a metal shoe or sole 8, by bolts 9, the soles of the two plungers being adapted to enter the mold box from the top and bottom respectlvcly.
At the contiguous faces of each plungermatrix and sole, I form a recess or chamber,
within which the electric heating element is installed. This recess or chamber, may extend elthcr entirely into the matrix, or entirely into the sole, or partly into the matrix lating mica sheets 12, which in turn are placed between a. pair of metal plates 13. Of these, that plate 13 which faces matrix 4 is insulated therefrom by an interposed heavy mica plate 14 while the plate 13 which faces sole 8 is in metallic contact therewith. Thus, while the main body of the matrix remains cool or unheated to a desirable extent, the heat is transmitted directly from the coil to the sole, to which it is confined, and where it is required to effect the neces sary lubrication of the mold. The various members of the heating element, 2'. e. the mica sheets 12 (with interposed resistance 'coil 10) and metal plates 13 are shown to be trio heating element may be closed on all of its four sides, but I prefer to have it open at one of its ends, so as to constitute a recess or mortise which latter construction is shown in the drawing. By making the chamber in this form the heating unit may be readily slipped into place, and may be inspected, repaired and removed, without first completely disconnecting the sole from the matrix of the plunger. However, if it should be preferred to employ a closed chamber, the heating element may be reached by first unbolting the sole from the matrix, so that with both embodiments, the heating element is rendered accessible.
I claim:
1. An electrically heated press for clay ware, comprising a plunger having a matrix, a sole, a chamber at the junction between matrix and sole, and an electric heating element within said chamber.
tween matrix and sole, and an electric heating element Within said chamber.
3. An electrically heated press for clay Ware, comprising a plunger having a matrix, a sole, a chamber at the junction between matrix and sole, said chamber being open at one of its ends, and an electric heating element Within said chamber.
l. An electrically heated press for clay ware, comprising a plunger having a matrix, a sole, a. chamber at the junction between matrix and sole, an electric heating element Within said chamber, said element being in lieat-transmitting contact with the sole, and insulating means between said ele ment and the matrix.
5. An electrically heated 131358 for clay ware, coi'nprising a plunger having a matrix, a sole, a chamber at the junction between matrix and sole and an electric heating element within said chamber, said heating element consisting of a resistance coil, a pair of mica sheets flanking the coil a pair of metal plates flanking the mica sheets, and a mic-a plate interposed between one of said metal plates and the matrix.
