'REFLECTOR FOR STREET-LAM PS.

SPECIFICATION forming part of Letters Patent No. 672,865, dated April 23, 1901.

Application filed February 8, 1901. Serial No. 46,504. (No model.)

whereby the same can be conveniently and. expeditiously attached or removed and which.v

will be applicable to various types or shapes of reiectors.

The nature, characteristic features, and

- scope of the invention will be more clearly understood from the following description, taken in connection with the accompanying drawings, forming a part hereof, in which- Figure l is a perspective View of a lantern, partly broken away to disclose the reiectorsupporting means. Fig. 2 is a top plan View thereof with the dome removed; and Eig. 3 is a perspective view of the reflector, showing the spring-fingers arranged at opposite ends thereof.

Referring to the drawings, l indicates the lantern-frame, 2 its removable dome, and 3 the burner, provided with the mantle 4 and tubular member 5, adapted to be raised and lowered over the mantle.

In practice it has been found difficult to mount the reflector in the precise manner that is required for obtaining its maximum effect Without in some way disturbing the tubular member 5 and more or less damaging the mantle. This is particularly true in fitting different types and styles of reiiectors, and naturally no little time is involved in the care and accuracy with which such operations must be attended.

In the practice of my invention I provide a duplex support or hanger one member of which is permanently attached to the lantern and is adapted to any style of reflector and whereof the other member is attached to the reflector. In this manner the reiiector can be changed at will with the exercise of little or no skill and without risk of injury to the mantle.

As shown in Figs. l and 2 of the drawings, the lantern is provided at its top with a shelf or ledge 6, which in turn is provided at opposite sides with depending straps or springarms 7. These are permanently attached to the middle or substantially the middle of said sides and are respectively provided near their lower ends with a transverse slot 8.

9 denotes a reiiector which has a central opening l0 for the passage of the tubular member 5 and is provided at its ends with spring-fingers 1l, which are bent upwardly and outwardly, so as to penetrate the slots 8 of the arms 7, which latter can be sprung to facilitate this purpose. The fingers 11 are provided with a hooked portion or claw l2, so as to positively engage the spring-arms 7;

It will be obvious to those skilled in the art to which my invention appertains that modifications may be made in detail without departing from the spirit and scope thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of the invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with the lantern-frame, of the slotted depending spring-arms attached to the upper part of the frame at opposite sides thereof, and of a reflector having spring members which positively engage said springarms, substantially as described.

2. The combination with the lantern-frame, of the depending spring-arms attached thereto, having transverse slots, and of a reflector provided with upwardly and outwardly bent fingers which penetrate said slots, said fingers having each a hooked portion or claw for positively engaging the spring-arms, substantially as described.

In testimony whereof I have hereunto affixed my signature in presence of two witnesses.

RUSSELL THAYEE.
