IMPROVEMENT IN STREET-LAMPS.

Specification forming part of Letters Patent No. 1 78,592, dated J une 13, 1876; application filed May 24,1876.

To all whom it may concern Be it known that I, JOHN MILTON BRUCE, of West Townsend, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Street-Lamps, of which the following is a specification The nature of my invention consists, first, in combining with a street-lantern cage a suspending-chain,said chain runningovera curve,

and thence down into a hollow bent tube, which forms a part of a bracket 5 second, in the method of constructing and combining the guide-pieces of the cagethe whole being an improvement on an invention secured to me by Letters Patent of the United States dated December 22, 1874, and numbered 157,906, entitled street-lanterns.

Figure l is an elevation of my invention. Fig. 2 is a longitudinal section of the same. Fig. 3 is a cross-section, showing the method of guiding the cage.

Let A R B B constitute a bracket, which is made fast to the wall 0 by bolts or nails.

The part A B. of this bracket consists of a hollow tube, curved at the top, as shown in Figs. 1 and 2. D is a lantern-cage, made in any convenient form and style. To the bail of the bracket-tube A, as shown.

as shown in Fig. 2. To the lower end of the chain H I aflix a weight, W, Fig. 2, this weight being just sufficient to balance the weight of the lantern, 850., so that the same will stand in any desired position. Thelantern is steadied and guided by the arms K K, which extend from the cage, and embrace the straight part M, Fig. 3, is a yoke, hinged at N to the part K, and held to the same by the screw P, so that when it is desirable to remove the cage from the bracket I have only to take out the screws P and turn the yoke M on the hinge N. This will free the cage from the bracket.

Having now described the construction and operation of my invention, what I claim is as follows:

1. The combination of the balanced lantern and cage D, chain H, and weight W with the tube-bracket R A B B, substantially as described, and for the purpose set forth.

2. The combination of the cage I) and hinged arms K M K M with the bracket-tube A, substantially as described, and for the purpose set forth.
