METHOD OF ATTACHING LAMPS TO LANTERNS.

Specification of Letters Patent No. 20,785, dated July 6, 1858'.

To all whom it may concern:

Be it known that I, JOHN FLEMING, of Pittsburg, in the State of Pennsylvania, have invented an Improved Mode of Attaching Lamps to Lanterns; and I do hereby declare the following to be a correct description of the same, reference being had to the accompanying sheet of drawings, in which Figure 1, is a perspective View of the lantern complete; Fig. 2, is a top view of the bottom plate of the lantern; Fig. 3, is a vertical section of a part of the lantern and lamp case, showing the attaching device.

The nature of my invention consists in the arrangement of parts, hereinafter more particularly described, for effecting an instantaneous attachment or detachment of the lamp of a lantern.

In the drawings, A marks the body of the lantern; B the case or holder of the lamp; C the bottom plate of the lantern; D the spring; E, E, the clips; F the conical ring; G, the slots in which the thumb and finger pieces H, H, work.

The same letter indicates the same part in all the figures.

I make the lantern in any of the known forms. On its lower plate C, I place a spring D as shown in Fig. 2. The ends of this spring pass through the slots G, Gr, and are then turned up to form the thumb and finger pieces H, H, by which the spring is compressed when desired. The compression is effected by bringing the pieces H, H, nearer together so as to occupy the positions shown by dotted lines in Fig. 1. Attached loosely to the spring D are clips E, E, the shanks of which pass up through a small slot in plate C and are bent around spring D as clearly shown in Fig. 3.

The expansion of the spring forces the shank of the clip outward and the lower part of the clip inward until it grasps the conical ring F and holds the lamp case B securely to the lantern. When the spring is compressed, by means of the thumb and finger pieces H, H, the clips are forced apart, into the position shown by dotted lines in Fig. 1, and release the ring F, allowing the lamp case B to become detached by its own weight.

The lamp can be attached and detached in any relative positions of B and C, and as readily in the dark as in the light. The operation can moreover be performed without liability to soil the hands with oil in handling.

Having thus described my invention, what I claim and desire to secure by Letters Patent is The combination of the spring D, with the clips E, E, and the ring F, for the purpose of effecting the attachment and detachment of the lamp of a lantern, all substantially in the manner hereinbefore described and shown.

The above specification signed and witnessed this fourteenth day of June A. D. 1858.

JOHN FLEMING.
