DAVID J.

MONDSIVIIT H,

To all "whom it may concern:

Be it known that 1, DAVID J. Monosiirrrrr, a citizen of the United States, and a resident of Spencer, in the county of Medina and State of Ohio, have invented a new and improved lncandescing Element for Burners, of which the following is a full, clear, and exact description.

lncandescing elements such as are used in connection with burners of the so-called calcium light type are not entirely satis factory for certain reasons, among which are that they have very little inherent strength and, are easily damaged, and they must be made of considerable mass in order to be of sutlicient strength.

The object of the present invention is to provide an incandescing element which has the required durability by reason of a reinforce being combined therewith, said reinforce taking the form of a backing for the body of rare earth which constitutes the real incandescing element. The reinforce, which may be of any size or form to perform the object for which it is intended, is preferably made of silicon dioxit, pure or nearly pure, although it is to be understood that other materials may be employed. The essential features of the backing are that it must be heat-resistant and strong. This backing may be applied to the incandescing body by cementing, fusing or any other ap proved manner, so that the resultant article is a unitary structure with an incandescing face on one side and a reinforce on the other, so shaped as to be mounted in a suitable support for use in connection with a suitable flame to produce a brilliant light.

"With such and other objects in View, the invention comprises various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, wherein similar reference characters are employed to designate corresponding parts, Figure l is a side view of a burner, showing the improved incandescing element applied thereto; Fig. 2 is a perspective View of the incandesch portion of the element; and Fig. 3 is a perspective view of a reinforcing portion of the element.

While the incandescing body 1 is shown in the form of adisk it is to be understood Epecifieation of Le ttcrs Patent.

Application filed March 7, 1913.

Serial No. 752,613,

that it may take any desired shape or size, and it is made of suitable fabric, which H in'ipregnated, burned and hardened. The backing 2 is shaped to conform more or less to the incandescing body 1 and is rigidly at taohed thereto, as by cementing or fusing, the reinforce serving to materially strengthen the incandescing body as well as to enable the latter to be made smaller than usual. Preferably, although not necessarily, the reinforce is made of silicon dioxid which porsesses a high degree of heat resistance, and at the same time the material is of great strength.

Various methods may be used for uniting the two bodies 1 and 2, but only two methods will be herein mentioned. According to one method the inoandescing body 1 is made in the usual manner and the reii'iforce is applied to one face thereof, in the form of paste, after such face is properly prepared, which face is allowed to dry, and then the whole element is heated, as in an oven, until the paste fuses together in a strong mass and fuses on the incandescing body.

According to another method the two parts of the element, namely 1 and 2, are separately formed and hardened and to the mating faces is then applied a suitable heatresisting cement. The cement-coated faces are then brought to ether and firmly seated by pressure, after which the element is heated so as to fuse the cement, to malre a strong union between the parts. An element of this form has great durability and strength and is capable of lasting a long time. The resultant element A, Fig. l, is mounted in a suitable holder 3 on the burner body B, which burner body has a gas-conducting tube t that directs the flame against the outer surface 1 of the incandescing portion of the element. 7

From the foregoing description taken in connection with the accompanying drawings, the advantages of the method of operation and of the device shown will be readily understood by those skilled in the art to which the invention appertains, and while I have described the device which new consider to be the best embodiment thereof, I desire to have it muierstood that. the device shown is merely illustrative and that such changes may be made when desired as are within the scope of the appended claims.

l laving thus described my invention, it

claim as new and desire to secure by Letters Patent:

1. An incandescing element in the form of a solid plate-like body composed of approxi- 1 inately similarly shaped parts, one part consisting of a homogeneous mass of incandescing material and the other of a mass of stronger material to form a reinforce for the incandescing material.

2. The combination of a burner, a holder mounted adjacent the burner, and an incandescing element carried by the holder in cooperative relation with the burner, said element being in the form of a body composed of a, reinforcing section set into the said holder, and an incendescing section carried by the reinforcing section and project ing from the holder.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
