GLOBE HOLDER Filed July 15, 1930 Patented Oct. 27, 1931 UNITED STATES PATENT OFFICE PAUL J'. PFEIFER, OFGLEVELAND' HEIGHTS, OHIO, ASSIG-NOR TO THE JOHN C. VIRDEN COMPANY, OF CLEVELAND, (PI-I10, A CORPORATION OF OHIO GLOBE HOLDER application filed July 15,

This invention relates to globe holders, and more particularly to means carried by devices of this character for detachably retaining globes and the like.

It is an object of the present invention to provide a spring biased retaming device which is constructed and arranged to operate'with a minimum flexing of the spring, whereby crystallization or fatigue of the 19 metal is avoided, and the life of the spring prolonged.

A further object of the invention is to pro: vide a recess to receive the retaining device in inoperative position, to increase the clearance for installing the'globe or the like.

Other objects and features of novelty will be apparent as the fOllOWihgdGSCllptlOn proceeds, reference being had to the accompanying drawings in which Figure 1 is an elevation of a globe holder according to the preferred embodiment of the present invention, showing a portion of the globe, and parts of the view be ng broken away to show internal construction;

Fig. 2 is an inverted plan view of the structure shown in Fig. 1;

Fig. 3 is an elevation of a portion of the globe holder adjacent the latching mechanism;

Fig. 45 is 'aview of a portion of the structure shown in Fig. 2,- showing the parts in latched position; and

Fig. 5 is an exploded view of movable parts of the latching mechanism as removed from the holder.

Referring more particularly to the drawings, the globe holder 10 may be of any desired construction or shape, preferably a cupshaped sheet metal member formed by stamping or spinning a fiat sheet to form a pleasing contour. The sheet metal is preferably brass but obviously other metals may be used for this purpose. The top of the holder 10 may be provided with supporting and win 45 ing apertures 11 and 12, and the lower portion of the inverted cup is provided with a flat, radial flange 13 and a depending annular flange 14 terminating in a rolled rim or bead 15.

The globe holder is adapted to support a 1930. Serial No. 468,002.

globe 16 which is provided with a flange or bead 17. Accordingly, the globe holder is provided with spaced abutment members 18 and a latching mechanism 19. The globe is inserted in the globe holder with the portion 17 in abutting relation with the abutments 18 and the latching mechanism 19 operated-to engage the other side of the portion 17 and thus hold the globe in the globe holder.

T he abutments 18 are preferably strips of a sheet metal, such as brass or other metals which are inherently pliable, or are annealed for this purpose. The strip of sheet metal is rolled or bent as at 20 to form the desired abutment, and secured inside the holder 10, as by rivets 9. This construction is of advantage in that the abutment 18 may be manually varied. The roll 20 may be gripped by pliers and permanently compressed, to thus provide a larger opening to receive the portion 17, or the roll may be spread or bent inward to decrease the opening. The portions 17 may vary considerably in diameter for globes of approximately the same size, and this expedient affords a very simple means for taking care of this variation.

The latching mechanism 19 includes a spring 21 which is secured inside the globe holder by means of a rivet 22. The spring 21 terminates in a notched end 23 which lies within the corner 24 formed by the flanges 13 and 14. Interposed between the end 23 and the corner 24 is a retaining member 25, best shown in Fig. 5, as comprising a rigid memher having a depending arm 26 and a shorter lateral arm 27. The portion 27 is adapted to lie between the end 23 and the flange 13, with the portion 26 depending adjacent the flange 1 1. The corner 28 of the member 25 fits in the notch of the end 23 and the spring 21 urges the corner 28 into the corner 24.

The flange 1a is preferably pressed out wardly to form an inwardly facing recess 29 above the head 15. A slot 30 extends transversely of the portion 29 just above the head 15 and is adapted to receive an operating member 31, best shown in Fig. 5. The member 31 comprises a head or cam portion 32 which is adapted to lie between the depending portion 26 of the retaining member 25 and the inner wall of the flange 14 at the pocket 29.

The member 31 also comprises an extension 33 which is of reduced width, forming shoulders 34. This extension is passed through I 5 the slot 30, so that the shoulders 34 rest against the flange'le within the pocket 29 and above the bead 15, thus forming a pivotal mounting for the operating member 31. e

'In operation, assuming that a rough adj ust ment of the rolled portions 20 has been made to suit the globe portion 17 of'the globe be-cv ing'installed, the operating arm 33 will extend radially through the flange 14, and thus the portion 32 will lie within the pocket 29 under the depending portion 26 of the operat ing member 25, which will also I be housed within the pocket 29. Thisarrangementpermits the latching mechanism'to clear the globe bead 17 as the. same is inserted into the flange 14. The operating arm 33 will then move upwardly, causing the cam portion 32 to move inwardly and cam the depending portion 26 of theretaining member 28 into engagement withthe outside of the globe bead 17, 'When the arm 33 completes its movement and lies snugly against the outside of the flange 14, the camportion 32 has'passed dead center, and thus the latching mechanism has a snap action which holds it in latched position. The inward movement of theportion 26 causes a downward movement of the corner 28 and consequent downward movement of the spring end 23'. This arrangement is important as it will be noted thatthe total movement of the spring end 23 is much less than the total "movement ofthe lower end of the portion 26. The provision of adequate latching action with a very small movement of the portion 13 and consequent 40 slight flexing of; the spring21 serves to prolong the-life of the spring'inasmuch as the liability of crystallization or fatigue of the metal of the spring is reduced to aminimum.
