RFLECTOR.

Specification of Letters Patent.

Patented June 5, 1906.

VAppia-.aon mea June 27, 1905. serial No. 267.282.

To all whom it may concern,.-

Beit known that I, EDMUND L. ZALINsKI,.a

' citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain novel and useful Improvements in Reflectors, of which the following is a full, clear, and exact description.

The present invention pertains to refiectors, and has particular application to animproved device embodying the essential and desired features of simplicity, durability, and effectiveness.

My improvement consists in the construction, combination, and arrangement of parts set forth and falling within the scope of the appended claims, and while I have in the present instance and for the purpose of illustration delineated herein one embodiment of my invention I wish it to be understood that I do not confine myself to all the precise details of construction herein set forth, as there may be modification and variation in certain f respects without departing from the spirit or exceeding the scope of my claims.

In the accompanying drawings, wherein l. like characters of reference indicate like parts in'both views, Figure 1 is a face view of an assembled reflector embodying my im rovements. Fig. 2 is a vertical sectiona view taken through the same.

Referring now to the accompanying drawings in detail, and especially to Fig. 2, the

.numeral 5 indicates the main outer casing of the reflector, which may be of any suitable -'shapeand form and constructed of any malfterial; but in the present instance I have [shown the reflector as approximately circu- `lar in contour, and for most purposes I have found it desirable to form the casing-box of brass. The reiecting-body proper, which is lindicated at 6, is in the form of a blown-glass plate approximately of parabolic form, the 4convex or'back face of such glass being provided with a coating of silver, as at 7. Over this coating of silver is placed a covering of 1 cloth or other textile, as at 8, the edges of the cloth extending over the edges of the glass, as

shown at 9. I then place at the back of this textile covering a layer of asbestos cloth' or other elastic non-heat-conducting material, such as is shown at 10, such layer being designed to permit the expansionof the mirror whenheated. At 11 Ihave shownabrass packis adapted to fit closely over the asbestos layer, the inturned edge portions 13 of this brass backing-plate extending over and bearing against the end surface of the mirror, so that when the parts are assembled thebacking layers and coverings will be clam ed to the convex face of the reflecting-glass y the backing-plate. The parts thus assembled are then placed within the casing, and one or more spring tension devices, such as the springs 14, are interposed between the backing-plate and the bottom of the casing, so that l the shocks and jars to which the reflector may be subjected to will to a certain extent be reduced, and at the same time the reflectingsurface will be at all times held in contact with the casing-covering 15. As will be noted by-reference to the drawings, this casing-covering is designed to fit over the edge of the box or'casing proper and is provided with a relatively large central opening 16, the edge of the wall surrounding said opening being beveled or inclined inwardly, as shown at 17. The casing-covering may be secured to the casing-box in any suitableA manner-such, for instance, by the small 5,

screws 18.

When the parts have been assembled in the form shown in Fig. 2, it will be observed that the reflector, with the backings therefor, will be Hush or held in contact with the under surface of the casing-covering, andany stated, the inter osition of the asbestos layer between the acking-plate and the textile sheet does not interfere with the extension of the mirror when subjected to heat, and the various parts going to make up the reilector may be easily and readily assemjars or shocks to which the reiector is subjected will be borne by the springs. As.

bled. By forming the glass body of the reflector of blown glass I am enabled to obtain a surface of great smoothness, which when silvered forms an exceedingly brilliant refleeting-surface.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a reflector, the combination with a reflecting-body, -a rigid backing, and a yielding backing interposed between said body and said rigid backing, of a case inclosing said rigid backing and a spring interposed between said rigid backing and said case,

IOO

l 55 ing-plate having the flanges 12, which plate `whereby shocks and strains transmitted to 11o A mi the back ofthe reieetng-body are cshioned by the spring and the yielding back-ing in succession.

2. In a reflector, the combination with a reflecting-body7 a rigid backing, a yielding backing and a layer of heat-insulating material inter osed between said body and said.

rigid bac in of a ease inelosing said rigidv backing, an a spring interposed between said rigid backing and said ease7 whereby shocks and strains transmitted to the back of said reflecting-body are cushioned by thev spring, the lreat-insulating material and the y1elding backing in succession.

3. In a reflector the combination with a reileotingbody, of a plate' behind said bodly EDMUND L. ZALINSKI. Witnesses:
