6 globes employed in White-way? street lightmg. I

One of the objects of the invention is the provision of a globe 'holdervwhich may be P permanently installed as part of the post equipment, and which may be brought beneath the globe for holding the same, when desired, for instance when the globe is to be lowered and swung out of its normal position while the lamp tender is changing or adj usting the lighting elements.

Another object of the invention is to provide a globe holder of sh adowless construction so that if desired it may, without dis-i advantage, be maintained in position as the normal support or holder for the globe.

Other objects of the invention will appear as the following description of a preferred embodiment thereof proceeds.

In the. drawings in .which .the same characters of reference are employed throughout the several figures to designate identical parts: 7 V

Figure .1 is a front elevation showing the top of a lamp post with three lamps with globe holders carrying out the principles of the present invention in operative relation thereto; v

Figure 2 is a perspective view of one of the globe holders; and v V.

Figure 3 is a detail of that form of the globe holder shown in the uppermost lamp in Figure 1.

figures it may be stated that the glassglobes employed in connection with the intensive Y lighting of citystreets and much-traveled platform for the lamp tender, to lower one Beforereferring in detail to the several of these globes and place it out oftheiway I while he is adjusting or changing the lighting elements of the lamp. Frequent break ages consequently occur so that the maintenance of this type oflamp includes a'substa-ntial item merely for unavoidable globe breakage. I I

Furthermore, the size of these globes is such that they present an extensive surface to wind pressure so that the flange of the globe with which'the usual supporting screws engage is frequently broken through wind pressure permitting the globe to be blown off and, of course smashed. The need for an auxiliary holding or supporting means is thus apparent, and the present invention is designed-to meet such a need. 1

' Adverting now to FigureQof the draw. ings, the lamp holder consists of a standard in general designated by the reference character 1 and consisting of. a socket portion 2 and a rod portion 3 the latter telescoping into the socket portion".

- Lateral arms 4 and 5 extend preferably radially from opposite ends of the standard, theupper arm at being provided with clamping means, the same consisting of a cap 6' having a recess 6 and adapted to be secured to a corresponding portion of the arm 4 having a recess 7, the recessed portions 6 and 7 cap6 may be secured byany suitablemeans such as screws and bolts, not shown, andthe mounting of the arm 4 upon the post is designed to be oflpermanent character.

In that form of the invention shown in Figure 2, the rod portion 3 is rotatable within the socket portion 2 and is also telescopically adjusted, a single set, screw 9 affording means for fixing therod for either of-these adjustments The lower varm 5 is provided with globe holding means comprising an annulus 10 supported by a spider 11, the latter being carried at the end of a rod 12 slidably and rotatably mounted in a suitable boss or collar 13 formed on or secured tothelaterjal arm 5. The rod 12 is adjustablevertically with respect tothe arm 5 and may. be held in. any

side of Figure 1;

position of adjustment by means of a set screw 14. The rod 12 is preferably coaxial with the recess formed by the recessed portions 6 and 7.

The operation of my improved holder for globes may be readily comprehended from an inspection of Figure 1, referring to the two lower lamps, the righthandone of which shows the holder in position with respect to the lamp while at the left the holder is shown with the globe, indicatedbydotted lines moved out of the way giving access to the,

lamp elements. At the right hand side the globe holder is shown permanently mounted, the annulus 10 supporting the globe in its normal position. The globe holdermay be left in this position if desi--red=,-or the lower lateral arm may be turned away from the globe as shown at the left hand side. When the lamp tender desires to remove the globe, .h'e swings the holder until the annulus 10 is beneath the globe. The upper screws 15, if are present, are loosened so that the globe may be withdrawn fromthe lamp and rest in the annulus, The set screw 9' is then loosened to permit the rod portions to be lowered with respect to the socket portion 2 a sufficient distance to permit the upper end of the globe to clear the part of the lamp with which it is associated. v

' While the set screw '9 is still loosened, the rod portion 3 together with the lower lateral arm '5 bearing the globe inthe annulus 10 is rotated to the position shown at the left hand Thereis no danger of the globe dropping from the hands of the attendant for it is stably seated within the annulus 1 0 and even while the set screw 9 is loose, if the attendant should inadvertently letgo of the lower arm 5*, the unbalanced weight of the globe puts a tilting stress upon: the rodportion 3- causing it to-bind within the socket so that it will not drop out. After the lamp has been tended, the lower arm 5 isv againswung. into place with the rod 12 coinciding with the axis of the neck 8, whereupon the lateral arm and rod portion 3 are pushed upwardly until the globe is again in its "normal position withv respect to the adj acen-t lamp parts. The set screw 9 is thentightened,

If it is desired to have the lower lateral arm 5 and annulus 1O normally out of the way,t11 e screws 15 or whatever other holding means may be provided are tightened, the

s'ts ciew 9 is loosened, the rod portion 3 Figural, to loosen the screws 15, and loosen the set screw 14,- thereby letting the annulus I0 descend with the globes- The-globe can then be rotated by hand, at the same time a wiping cloth is applied to its exterior surface. Since the globes are'spherical, the annulus 10 affords a seat for any portion of the globe excepting, of course, where it is open at the top part. Therefore, for washing the inside of the globe, it, is only necessary when it has been sufieiently lowered, either by lowering therod 12 or the rod portion 3, to tilt the globe, in the annulus 10 until the open top portion comesto aposition convenient to the attendant, ,o

lt-maysometimes be desirable in lowering the globe prior to turning it out of the way, to leave the set screw 9 tight and to loosen the set screw 14, thus lowering the annulus-10' and globe with respecttothe lower lateral arm 5. 'Sincethe globe is then in balanced relation with respect to thel-owered part, this operation is more easily performed than by lowering the rod portion 3 and lateral'arm 5.

It; is preferred to make the annulus and spider 11 of wire, thus providing a construction which is substantially shadowlessso that there is no objection, if desired, to leaving the holder in its operative position as shown at the right hand side of Figure 1. Itis obvious that this provides a strong and rigid being blown down.

At the top part of Figure 1 is shown an adaptation of theglobe holder for globes which are normally supported from beneath linstead of being suspended. In this form the globe holder does not serve as an aid to i .the attendant, but solely as a permanent auxby a dished member 16 adapted tore'ceive and bear down upon the upper portion of the globe. For removing. thisgl'obe, it is necessary to loosen the set screw Sand toraise and rotate the rod portion 3- and dished member 16.

It is to be understood that in the foregoing description of the accompanying drawings, I have illustrated my improved holder for globes in elemental form, for the purpose of exemplifying its structural features, and that asactually manufactured and installed itmay be embodied in an ornamental form to harmoni 'zewiththe decorative motif of the post with which it is associated.
