TUBULAR LANTERN:

Application filed December 8, 1908.

To all whom it may concern:

Be it known that I, VVILLIAM O. EMBURY, a resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Tubular Lanterns; 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 pertains to make and use the same.

This invention relates to tubular lanterns, and particularly to means for raising and holding up the globe, the improvement being more particularly applicable to tubular lanterns in which the globe is held down by a spring.

The invention consists in the construction hereinafter described and particularly pointed out in the claims.

In the accompanying drawing which illustrates the invention and forms part of the specification,-Figure l is a partial elevation of a lantern with the improvement attached, and Fig. 2 is a similar view at right angles to Fig. 1.

In the drawing numeral 1 denotes one of the usual air tubes of a lantern, 2 the globe, and 3 the globe holder.

4 is a cranked globe-lifting lever supported in a horizontal bearing on tube 1, as shown, the forward or handle end 5 being extended forward and upward and free to be moved downward without any preliminary unlocking.

On the outer side of the tube 1 below the bearing is fixed a spring hook or catch 6, having a handle-engaging part provided with an open or flared top to admit the handle arm when the latter is pressed down, and the spring being bent or contracted so that the handle has to be forced past it in a direction lengthwise of the lantern, and the spring being of strength to hold the globe up against gravity, when no globe spring is used, or against gravity and the spring when the globe is spring pressed. Preferably the spring is made of spring wire bent double, as shown, the two end portions thereof being secured to the usual side flange 7 of the air tube on opposite sides of the flange for ease and strength of attachment. The handle arm is bent to such shape that when entered in the spring hook it extends across the hook at right angles so as to be held Patented April 20, 1909. Serial No. 466,548.

efliciently. Owing to the swing motion of the arm in entering the hook such entrance is easy. With the described construction the handle can be pulled directly down, that is, by exerting pressure in a single plane parallel with the length of the lantern, and without a preliminary force transverse to the length of the lantern. This makes itpracticable to operate the handle by use of one hand, and without necessity of holding the lantern with the other hand, as required in constructions where the handle is locked in its extreme positions by entering notches or behind shoulders having abrupt or looking sides from which the handle must be disengaged by a force transverse to the length of the lantern before it can be swung down or up.

The invention is not limited to the exact construction of spring hook described, nor to the shape of the handle arm. The connection between the lifter and the globe may also be varied.

I am aware that plates with guide slots for a lifter handle and having right angle slots at top and bottom, or either, to hold the handle until released by a sidewise pressure, secured to lantern tubes, are old, and such I do not claim. Neither do I claim a wedge shape lug secured to such tube in manner to allow the handle to be pressed down, but requiring a sidewise force to return it, this being old.

My device is easier of operation than such devices last referred to, and is strong and simple.

Having described the invention what I claim is,

1. In a tubular lantern, the combination with a globe, a globe-support, and a globe lifter having a crank connection with the globe support for raising and lowering it, said lifter being upright portion of the side tubes and transverse thereto, said lifter having a handle which when the globe is in normal position extends upward above the pivotal connection on the side tubes and is free to move from said normal position, of a spring secured toa. side tube adjacent said handle, and having an engaging part below such handle, the engaging part being open for entrance of the handle and bent to hold the handle when it has been entered, said bent part hai'ing a term which permits the handle being pushed past it by pressure in a I plane lengthwise of the lantern.

In a tubular lantern, the combination with a side tube, and a globe lifter having a pivotal connection on the upright part of the side tube, the lifter having a hand normally extending upward from the pivot and free to be moved downward, of a handle holder in the form of a hook secured to the side tube and having the handle-engaging hook part below such handle, said handle-engaging part being open for en- 1 trance of the handle and contracted to hold the handle when it has been entered, said 15 contracted part having a form which perinits the handle to be pushed past it by presl sure lengthwise of the lantern.
