Application vtiled January 24.1913. Serial No. 743.998.

lie it known that l, @Hannes F. Massey, a citizen ot' the United States. and resident ot Chicago, in the county of Cook and State ot' lllinois,v have invented certain new and uset'ul Improvements in Lamp Si'ipportingl Structures, ot' which the following is a Speci- 'tication My invention relates to lamp supporting structures, particularly to that class adapted .for use tor street lighting purposes. Among the important objects: are to provide a structure of which the parts can be readily formed up of concrete or other eei'nent' material; to provide a construction and arrangei'nent in which lamp supporting brackets are detacl'iable in order that shipment can belmade with greater safety and in more conopact form; to provide improved means for prixi'iarily Supporting brackets in placewbile grtniting is applied to till inthe spaces between the' inner ends of the brackets in order to form a compact, solid and rigid structure; to provide conduit pipein each iracket which will act .also as reinforcingl for such bracket and which has an upturned innerend to form a hook for receiving the means for primarily holding the bracket arms in propeigposition while the grouting is applied; to provide the conduit. pipe in each brackets with upper and lower outlets at the end ol the. bracket. so that lamp structures may be applied either to the topsoi the brackets to be held in up-righl position, or to be `applied to the lower sides el the brackets to hang therefrom; lo provide a conduit pipe at the interior ol the post whose upper end extends between the inner end ot the brackets to torni an abutment therefor; to provide a compartment at thc-upper endet-the post head into which the post conduit and the bracket.conduits extend and in which compartment'. connections may be made between main supply conductors 1n the ypost. conduit and lead conductorsrunning through the bracket coi..r

duits` to the lampstructures; to provide a .cap for the post head construct-ed of eoncrete and having a duct for supportinor a top lamp structure and which communicates with said compartment, and in general to provide improved, simplified andmore de sirable construction and arrangement in a lamp supporting structure of the class reterred to.y f

ln the accon'ipan \,'ing drawings Showing the various features ofthe invention: Figure l. is' an elevatioiml view with one ot' the lamp stiaicture."y removed and the end of one bracket in section; Fig. 2 is a plan View with thc eap removed; Fig. 3 is an enlarged sectional view of the post head taken on plane f-hf, Fig. Q, showing the inner ends of the brackets supported therein just before application of the grouting material; Fig. 4 is a sectional view taken on plane fil-4, Fig. El. and Fig, 5 is a sectional view taken on plane 5&5. Fig. l.

Reterring to the drawings a post 5 is built up integral ot' concrete which may be properly reinforced in any suitable manner. 'lhe head (i is polygonal and has` lateral passageways 7 each extending from the center to one olj its faces t'or receiving the lamp supporting` bracket structures 8. These passageways are formed by inserting a Core in the mold, and when the core is removed only the corner posts t) will remain between the base t3 and top 6" ot the head, the lateral channels 7 being between these posts. As shown in the drawings, the head rectangular and has lour lateral passageways for receiving and spacing four brackets ninety degrees apart. The top Gl of the head is hollow lo t'orm a compartment l0 for containing the. electrical joints as will bedescribed laterA The peat 5 has running centrally therethrough a pipe ll which extends centrally through the head between the corner posts and terminates in eon'lpartinent 10 for lead ing current supply conductors 'l2 to said eonnnzrtn'ient from the base ot the post where such conductors` connect with mains in the street.

Each lamp supportingbracket S is tin-ined integrally ot concrete or other ccn'ientitious material and comprises a body part Sf-Lwhich its snugly into one oll the passagewayh T of the head between the, adjacent corner posts. ltlxtending laterally from the upper end ot' :he body part is anl arm SL' and extending diagonally upwardlj.' trom the lower end ol the body part is' the brace 8, the end` 8 being of rectangular cross section as shown. Extending longitudinally through the arin Sb is the pipe l?) whose inner end 11:5 is deflected upwardly and ,spaced a. distance from the body to leave a groove ll. The outer end of this pipe terminates in a Tfpipe fitting 13b Whose upper end is lushwith the top surface ot the arm and whose lower end receives an extension 13C which projects bcyond the lower tace 8 of the bracket for receiving lamp supporting mechanism. The inner end 8 ot the body 8 of the bracket is tapered and of conical form, this end beine` below the pipe end 13a. Each bracket structure is reinforced in any well known manner and the piping running therethrough also serves to strengthen the structure. When the brackets are to be applied to the post the bodies thereof are inserted in the various channels 7 which they snugly tit and with the ends S abutting against thc pipe ll. extending through the head o't the post. ring 15 is then dropped into the groove llbetween the pipe ends 13 and the body parts and the brackets are thus held in proper position. Such ring may be in the nature of several turns ot' wire looped about the pipe ends lil". frt'ter the brackets are thusl locked in place grouting material lt' is poured into the pockets 17 between the tapered 'laces ot the ends Se and the entire head structure thus becomes solid up to the tops ot the brackets. \Vhen the brackets are thus secured the pipe ends 13 all open into the compartment l0 and this compartment will accommodate the joints between the main supply conductors 1Q and the. leads lb running through the pipes 123 to the lamp structures. The upper end of the post and the compartment 10 are preferably covered in order to protect the conductors` and joints and I therefore provide a removable ea p it) of concrete, and this cap mayserve also to support the lamp structure l which is supported from the end of a pipe l0 extending centrally through the cap and leading to compartment l0 so that connection can be made between the l"ads to the lamp and the main supply conductors.

s the pipes lil have outlet to both the tops and bottoms ol the structure ends, the lamp structures l may be supported in upright position on the tops ot' the brackets or to hang l'rom thex bracket ends as shown in the drawings. When the lamps are hung as shown, plugs ll are screwed into the upper ends et' the T-tittings lll" to protect the leads withinthe piping. When the lamps are hung as shown. the threaded outer ends of the extensions lll" receive holders /L for globes g. These extensions are usually of larger sized pipe and reducer tittings 7- are therefore applied thereto on which lamp sockets s may be secured tor receiving the lamps When the lamps on tho brackets are to be supported in upright position the plugs 2t are rcmovtd and suitable pipe lit'- tings inserted in the Tdittings to support the lamp strmttures, and the extensions 13 are then preferably capped to protect the conductors within the piping lit.

The post may also be adapted tor accommodating illuminated sign plates. One arrangement is clearly shown in Fig. 5. The compartment Q2 is formed in the post and extends across one corner thereof in order to have the side outlets and 2l which are covered with glass or other plates and lo on which the street name is painted or otherwise provided. The corner section 27 will secure one'or more lamps 28 and on the rear wall Q9 of the compartment a reflector IKO is provided for reflecting the light from the lamps through the letter plates.

I thus provide a lamp supporting struc ture in which the Various parts can be readily built up of concrete or other cen'ientitious material. The bracketsl being llat can be compactly packed for shipping purposes and a'titer the post part is installed inthe ground, these brackets can be quickly inserted in the head channels and the ring slipped over the pipe ends 13 and the grouting material poured in so that the brackets are then securely held:in/proper position and alinement. Connectiions are then made between the main supp'y conductors and the lamp .structure leads and the cap then applied. The brackets c'an of course be applied before thc post is set into the ground-it desired. lt one ot the Ibrackets should at any time be broken it can be readily removed by withdrawing thel ring 153 and replaced b v another bracket. 'l'he entire structure has a very neat and pleasing appearance.

t do not desire to be limited to the precise construction and arangement shown and described as changes and nuulitications are no doubt possible which would Istill come within the scope of the invention as set up in the following claims:

1. ln af lamp supporting structure, the combination with a post, ot a plurality of lamp supporting bracket trames, said post having a plurality of channels or pockets extending from the interior thercot to the various sides thereof, the inner ,ends ot `said brackets fitting into said channels or pockets` hookedtextensions from the inner ends ot said bracket frames, and a ring engaging with said hooked extensions to lock said bracket frames in said channels or pockets.
