LIGHTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 729,303, dated May-26, 1903. Application filed July 2, 1902. Serial No. 114,104. (No model.)

To aZZ whom it may concern.-

Be it known that I, LEONARD ERIKSON, a citizen of the United States, residing atMalden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Lighting Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to lighting devices specially adaptedfor use in connection with the show-cases used in stores; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a front view of the lighting device. 'Fig. 2 is a cross-sec tion taken on the line or a; in Fig. 1. Fig. 3 is a cross-section taken on the line y y in Fig. 1. Fig. 4 is a detail rear view of the insulating-block.

A is a trough-shaped reflector of polished metal having a tubular bead b at its lower edge.

B represents brackets for securing the reflector inside the show-case. Each bracket has a lug c, which is attached to the showcase by screws, and a hook d, which engages with the tube 1).

O is a curved arm which is pivoted to the.

upper end of the bracketB and provided with a series of notches e in its sides. The reflector has a hole f in its back, which has a narrow slot f on its lower side. The arm 0 is slid through the hole f, and its notches are placed in engagement with the slot f. In this manner the reflector is supported from the brackets B, and its position can be adjusted from time to time to throw the light to the best advantage inside the show-case.

D is a block of insulating material secured at the middle part of the reflector.

E represents two incandescent electric lamps of any approved manufacture secured to the block D and projecting from it in opposite directions inside the trough of the reflector. i

The block D has two recesses g and 7?. at its middle part, and g andh are two metallic bridge-pieces arranged in these recesses, respectively. Thebridge-piecegisarranged on the axis of the lamps and isconnected to their central terminals. The bridge-piece 7b is arranged to one side of the axis of the lamps and is connected to their other terminals. The line-wires '1; and i are passed up the tube 1) and are connected to the bridge-pieces g and h, respectively, by binding-screws.

The two recesses g and 77. have a shallow recessj formed in the block D around them,

- andj' is a curved plate of insulating material arranged in the recess j between the bridgepieces and the metallic'reflector. The block D has a longitudinal groove is along its lower edge, which engages with the front part of the tube 19. The block is held in position by this groove it and a screw it, which engages with a hole in the upper edge-of the reflector and a hole in the said block.

WhatI claim is 1.-'The combination, with a trough-shaped reflector having a tube at one edge and holes and slots in its rear part, of oneor more lamps arranged inside the reflector, supportingbraekets having hooks which engage with the said tube, and arms pivoted to the said brackets and provided with "notches for engaging with the said slots, substantially as set forth.

2. The combination, with a trough-shaped reflector having a tubeat one edge, of ablock LEONARD -ERIKSON. Witnesses:
