Patented Dec. 31, 1 929 UNITED STATES PATENT OFFICE JAMES A. ONEIIgmOF LYNN, MASSACHUSETTS, ASSIGNOR T GENERAL ELECTRIC COM- i PAN Y, A. CORPORATION OF NEW YORK GLOBE HOLDER Application filed flctober 18, 1928. Serial No. 313,320.

My invention relates to globe holders; more particularly it relates to holders of the type that are especially adapted for use in connection with globes for enclosing light sources such as are ordinarily used in highway lighting. The invention is particularly adapted for use in connection with globes which are seated in a casing located usually at the top of a pole'. It is an object of the invention to provide a holder having means forreadily clamping and unclamping the globe in position, without the necessity of operating screws and the like which require .special tools and considerable time to opcrate. However, the invention will be more readily understood in all its details from the following specification and claims, reference being hadto the accompanying drawings inwhich:

Fig. 1 is a view in elevation of a light unit comprising the holder of the invention located on a casing.

Fig. 2 is a top enlarged View of thecasing, Fig.1, showing the adjustable clamp and the strap that encircles theglobe. In this figure the globe has been omitted'and the clamp hasbeen shown in the unlatched po- Fig. 3. is a view, similar to that of Fig. 2, of the casing and the clamp elements. In this figure the clamp is shown in the latched position with the strap drawn tight around the globe, the globebeingshownin section taken along line 3-3, Fig. 1. e

Fig. 4 shows the clamp element in an enlarged side view. In this figure the clamp is shown in the unlatched position similar to Fig. 5 shows a section of the clamp taken Fig.6 isa top viewsimilar to Fig. 3 showing another form of the. invention.

. Only a section of the base is shown in this is provided with a ing 3.

Fig. 9 is a section taken on line 9--9, Fig. 8.

Referring more in detail to the drawings, it will be seen that the unit shown in Fig. 1

globe resting on the cas- On the top of the casing, between the globe 2 and the flange 4, see Fig. 3, I providea strap 5 which is looped about the base of the globe. This strap may be, for example, in the form of a wire, one end 5 of which is anchored in any suitable fashion to the flange 4. The flange as shown in Fig. 5, is provided with a terminal in the form of a clamp A which is interlocked with the flange as indicated in Fig.5. The clamp is loosely mounted on the flange so that it may be slid along the flange in either direction as indicated by the arrows in Fig. 2. In one form of construction the clamp is made in two sections 8 and 9 as indicated in Fig. 5, these two sections being held together by any suitable means as, for example, by screws 10. However, the clamp may be formed in one continuous piece with the edges folded over to correspond with the edges 6 and 7 Fig. 5.

Referring to Fig. 4 it will be seen that the clamp is provided with a bifurcated spring member 11 suitably anchored to the base of when the lever is thrown in the reverse posi tion, as indicated in Fig. 3, engages the out- Obviously, therefore, by unlatching the clamp A, as indicated in Fig. 2, and sliding the clamptothe left the loop formed by the 1sideof the flange 4, thus tightly drawing the element A against the flange 4.

strap 5 is allowed to expand by sliding through the eyelets 16 which latter are anchored to the base 3. The globe is then placed in position, as indicated in Fig. 3. The strap may then be tightened around the globe by advancing the elements A in a clock wisedirection, thus closing the loop about the neck of the globe. The lever 14 is then thrown forward or clockwise as indicated in Fig. 3, thus locking the globe securely in position. Of course in order to remove the globe, the reverse operations are performed.

Referring to the form of device of the invention shown in Fig. 6, the strap 17 is the same as the strap 5, Fig. 2, one end of which is secured to the base element 18 at the point 18". In this form of device, instead of having the strap pass through eyelets 16 secured to the upper face of the base element 3 it passes through eyelets on the end of pins 19, which extend through the flange element 20 corresponding to the flange element 4, Fig. 3. In

. place of the sliding clamp A, Fig. 2, in this form of device a lever element 21 is used which is secured to a block 22 on the outside of the flange 20 by means of a pin 23. The lever 21 is provided with an adjustable terminal block 24 to which the other end of the strap 17 is secured. The block 24 is in threaded engagement with an adjusting screw 25 which passes through an opening 26 in the head of the lever 21. Between the head 27 of the screw 25 and the head of the lever 21 there is provided a compression spring 28. With the construction shown in Figs. 6 and 8 it will be seen that the strap 17 may be loosened by raising the lever 21 from the positionshown in Fig. 6 to the position shown in Fig. 8. In order to tighten the strap the 1ever21 is moved from the open position such as shown in Fig. 8 to the position shown in Fig. 6. The object of the spring 28 is to allow the screw 25 to yield when the lever is being moved from one position to another during the process of latching and unlatching the globe. If the strap 17 should be found to be loose when the lever 21 is in the position shown in Fig. 6, it may be tightened by turning the screw 25 by means of which the adjusting block 2 1 can be advanced in either direction parallel with the axis of the screw.

By my invention I provide an improved holder in which the strap is completely looped around the globe so that the end portions of the strap overlap. With this arrangement it is possible to draw the loop more snugly and effectively around the globe. Furthermore, while the strap has one end anchored to the base the other end is provided with locking means comprising an adjustable terminal so constructed that the terminal may be pressed against the smooth outer surface of the base in any position between two points on said surface rather than against tooth elements formed on the base. WVith such an arrangement it is possibleto adjust the loop snugly and without causing any excessive strain. In the form of terminal shown in Fig. 2, the head 15 is adapted to engage the smooth outer surface of the casing between two points, while with the form of terminal shown in Fig. 6 the block 24 may be pressed in any position between two points against the smooth outer portion of the base. With this latter form of terminal the position of the block 14: is determined by the screw 27. Furthermore in this form of terminal the cushion spring 28 which is interposed between the head of the screw 27 and the arm 21 enables the arm 21 to pass the neutral point without the danger of overstraining the globe as the arm 21 passes from the unlocked to the locked position shown in Fig. 6.

It will be understood that while I have illustrated and described my invention in connec'tion with specific forms of the invention shown in the drawing, I do not wish to be so limited inasmuch as I contemplate modifications and variations within the spirit of the invention and the scope of the claims contained herein;
