LANTERN.

Specification of Letters Patent.

Patented 4, 1908.

T o all whom it may concern.:

Be it known that l. lfurmanicn KYRIGIIT, a citizen of the l'nited States, residing at Syracuse, in the county of Onondaga and State of New York, have invented a new and useful Improvement in Lanterns, of which the following is a specification.

This invention relates to loops, staples, bearings, posts and similar fixed parts which are used in lanterns for confining or guiding Pmovable parts, for instance, to the guide loops or st. )les which are secured to the side tubes o tubular lanterns for confining and guiding the upright wires or rods of the vertically movable globe frame or suport, to the bearings in which the lifting evers are journaled. and to the posts which project upwardly from the base portion of the lantern and enter an opening in the de- 2o tachable globe plate for preventing the latter from turning on the burner. -These loops and other devices ha ve usually been secured to the tubes by soldering.

rl`he object of this invention is to secure such devices to the tubes or other supports by more durable and` reliable means and without requiring the expensive operation of soldering.

In the accom anying drawings; consisting of two sheet-s: figure 1 is an elevation of a. tubular lantern in which the guide loops are secured to the tubes b v this invention. `Fig. 2 is a fragmentary inside elevation of one of the tubes preparatory to applying the guide loop thereto. Fig. 3 is a fragmentary secvtional elevation of the tube with the guide loop applied thereto. Fig. 4 is a horizontal section in line 4 4. Fig. 3. Fig. 5 is a perspective view of the guide loop. Fig. 6 is a perspective view, showing another construction of guide loop embodying the invention. Fig. 7 is a horizontal section of the loop shown in Fig. 6. Fig. Sis a vertical section, showing another construction of guide loop embodying the invention. Fig. f) is a hor1- zontal section in line 9 9, Fig. S. Fig. 10 is a fragmentary horizontal section, showing another construction of guide loop embodying the invention. Fig. 11 is a perspective view of this loop. Figs. 12 and 13 are fragmentary vertical sections in lines 12;1'2 and 12S-13, Fig. 10. respectively. Fig. 14 is a fragmentary elevation, showing the bearing of the lifting lever secured to the tube by this invention. Fig l5 is a vertical section in line MfS-15, Fig. 14, on an enlarged scale. Fig. 1G is a fragmentary sectional elevation, showing a posten the lower air chamber secured by this invention.

Like reference characters refer to like parts 00 in the several figures.

A represents the side tubes forming part of the rigid frame of a tubular lantern and B the upright side wires or rods forming part of the globe frame which is movable vertically in the rigid lantern frame in a well known manner.

C represents the guide loops which are secured to the inner sides of the\tubes and projectv inwardly therefrom for `-confining and guiding the upright wires or inembers B of the globe frame. These guideloops are provided for attachment to the uprig 1t tubes or members of' the lantern frameivith barbed attaching shanks which are passedk through openings or slots in the inner walllof the tube or supporting member. The\b`a\rb is flexible and forced out of its normal position in inserting the shank into the opening f the frame and returns to its normal positief. after it has cleared the opening, whereby the barbed shank assumes a position in whicl'\ it secures the loop to the tube or support against withdrawal or accidental detachment.

These barbed attaching Shanks may be construeted in various ways, some of which are illustrated in the drawings.

In the construction represented in Figs. 2-5, the guide loop is provided at each end with attaching shanks 20 which are bent 90 back upon themselves to form barbs 21 and the loop is provided, preferably above and below each shank, as shown, with shoulders 22 which limit the inserting or forward movement of the shank. The tube or support is 'provided for the reception of the attaching shanks with upright slots 23 which are so narrow that in inserting the barbed shanks into the slots the barbs are pressed out of their normal position toward the shanks. 'hen the rear ends of the barbs have cleared the slots the barbs spring back to their normal position and engage against the interior side of the inner wall of the tube, asfrepresented in Fig. .f. he shoulders 22 at the base. of the shanks bear against the exterior side of the inner wall and prevent further movement of the loop in the inserting direction and the barbs bearing with their rear ends against the interior side of the inner wall In the construction represented in Figs.A

6 and 7, the barbs 24 are formed. on the Shanks 25 by slitting the latter and bendin@ the barbs outwardly.

n the construction represented in Figs. S and 9, the barbs 26 are formed on the shanks 27 in the manner shown in Figs. 4 and 5 by bending the Shanks back upon themselves, but instead of forming stop shoulders at the bases of the shanks, as in the construction represented in Figs. 4 and 5, the shoulders are omitted and the shanks are made so long that they stop against the outer wall 2S of the tube when the shanks have been inserted. In this position of the arts the shanks are held against further orward movement by their ends bearing against the outer wall of the tube and against backward movement by the barbs.

In the construction represented in Figs. 10-13, each shank 29 is provided with two barbs 30 formed at the upper and lower sides of the shank and tapering forwardly, so that each barbed shank has aiproximately the form of an arrow head. 'The barbs are bent so as to stand normally at a slight angle to the plane of the shank. In inserting the shanks into the upright slots 31 in the tubes the barbs are deflected out of their normal position b v the side walls of the slots, and when the barbs have cleared the slots they spring back to their normal position and lock the loop to the tube.

The loo s and their barbed shanks are made of sieet brass, tinned sheet steel or other suitable material possessing the necessary Ilexibility and elasticity.

In lthe construction represented in Figs. 14 and 15, the bearing 32 in which the liting lever 33 is journaled is secured to the tube by barbed Shanks 34.

In the construction represented in Fig. 16, the post 35, which enters in a well known manner an opening in a detachable globe plate 36 for holdingr the latter against turning, is secured to the top plate 37 of the lower air chamber by barbed shanks 3S.

I claim as my invention: 1. The combination with a supporting tube provided with a slot, of a loop having a barbed attaching shank which projects into said 4tube thrmlgh said slot and bears with its barb against the inner side of said.

tube, said loop being provided with means for arresting its inserting movement when the barb .has engaged against the inner side of the tube, suliistantially as set forth.

2. The combination with a supporting tube provided with slots, of a loop or staple having barbed attaching shanks which project into the tube through said slots and which bear with their barbs against the inner side of the tube, said loop or staple being provided with means for arresting its inserting movement when the barbs have engaged against the inner side of the tube, whereby thc loop or sta )le is rigidly secured to the tube, substantially as set forth.

3. The combination with a. support-ing tube provided with slots, of a loop or staple having barbed attaching shanks wlnch project into the tube through said slots and which bear with their barbs against the inner side of the tube, said loop or staple being provided with stop shoulders which bear against the outer side of the tube, sub

stantially as set forth.

4. 'lhe combination with a lantern frame having an upright tube provided with slots, and a globe support vertically movable in said frame along said tube, of a guide loop for said support having barbed attaching shanks which project into the tube through said slots and bear with their barbs against the `inner side of the tube, said guide loop being provided with means which limit its inserting movement, whereby said guide loop is rigidly secured to said tube,sub stantially as set forth.

'itness my hand in the presence of two subscribing witnesses.
