SIGNAL LAMP.v

Appiicatiqn flied Maren a, i925. ,seriai- No. 12,431.

Aof the character specied in which theA parts thereofmay be readily assembled for use, or separated for inspection or repairs, and in which said parts may be readily 'positioned so that a given light may be displayed along theV line.

Further, said invention has'for its object to provide a lamp of the'character specified in which the several parts thereof are so constructed and arranged that wh'enthe same are united they will form a wind and weatherproof structure.v

Further, said to provide a lamp of the charac-ter specied consisting essentially of a lantern body and a base and having a supporting bracket per manently connected to the base member upon which the lantern body is rotatably disposed so that the same may be adjusted to any one. of a light. l l

Further, said invention has for fits object lto provide a lamp ofthe character specified which consists of two enclosing parts having portions adapted to interengage -to maintain the parts against separationrwhen asseii'ibled,

4and to permit ofthe relative rotation of the Further said linvention hasfor its object to provide a lampjof the character-specified in which the base member'may be rigidly supported in position, andthe lantern'body rotatably `mounted upon said base vso as to permit of the ready and convenient adjustment and securement of the lantern body to a plurality of signal displaying positions and ends my invention consists' in t-he novelA `details of construction, and in the combinainvention has for its objectplurality of positions to display a given part be obvious andl tion, connection and arrangement of parts hereinafter more fully vdescribed and then pointed out in the claims. l

In the accompanying drawing showinganr `illustrative embodiment of the invention-7' Figure 1 is an elevation of one form 4of lamp' constructed according to and embodying my said invention; Y f Fig. 2 is an'elevation thereof partly in section; j y

Fig. Sis an elevation thereof with the upper and lower parts thereofshown separated; j Fig. 4: is

y a bottom plan of the upper membeneed Fig. 5 is a top plan of the lower member. ln said drawings the signal lamp is shown as consisting essentially of a base member 10, and a separate -top member'or lantern body 19Ywhich is revolubly supported upon said base v10.

rlhebase member 10vjis preferably in the form of a relatively shallow circular receptacle vhaving a raised bottom 10a, and vertical wall terminatingat its upper edge in anv outwardly projectingvledge or rim 18;

To support the lamp, asa whole, in position upon a fixed support, the base member 1Q is provided with a laterally extending arm 16 having an attaching bracket 17 at its outer end. By preference the said arm and bracket `nre formedintegralv with said base memer 10. Y

secured to yand i l y Y '85 The top member or vlantern body 19 is' hollow, and si'ibs'tantially spherical inQform and? provided in its sides `with a' plurality of openings1in-whicli'are secured '

signal lightsfor lenses

20, 21, 22,' 23, ofdiiferent colors to meetV the requirements of the railroad orother purpose in connection with which the lamp is used. The' number of signallights is uniml portant and may be varied to meet any given condition.

I The Vopen 'lower vportion of said lantern 4body 19Vterminates in'a depending annular lflange or wall portion 25 adapted tofully receive and enclose the vupper portion 'of the base 10. Thel flange 25 is provided iipOiiit-s inner upper edge with aninwardly extending rannular' shoulder 26 which is adaptedto rest upon the upper surface of the outwardly projecting ledge or rim 18, and' to ride thereon when-said lantern body is rotated relatively to said base'. The ledge or rim 18 also serves as a spacing member to maintain the-wall portions of the

parts

10 and 19 separated in concentrically spaced relation. Vhen the

parts

10, 19 are duly assembled the line of jointure of said parts will be well within, and be protected by the depending flange which serves as a rprotecting apron'in rendering the lamp wind and weatherproof.

To hold thebase member 10 and body portion 19 duly connected, and to allow of the rotation of said body portion upon said base member, the depending flange 25 of the body portion 19 is provided upon its inner side, in spaced relation to the shoulder 26, with inwardly projecting

lugs

27, 27 adapted to engage with the underside ofthe ledge` or rim 18 of the base member 10. The flange 25 is also provided, intermediate said

lugs

27, 27,

with a similar but smaller `lug 28 which is adapted to be received by the recess 29 in the ledge or rim 18 ofthe base member 10, and, after partial rotation, to engage with the underside of the ledge or rim 18 of the base member.- The lugs 27 23 are y preferably formed integral with the flange 25.

v In order tohold the lantern body 19 to any one adjusted vposition substantially ninety degrees apart, upon the base member 10 to display any one of the four signal lights, the

'lantern body is provided at its flange 25 with a radially extending casing 31 in which is disposed a normally projected spring-pressed plunger for pin 30 having ahead 30a at its outerp'end. The normally projected end of said member. 30 is' adapted to engage with any of four recesses`32'provided in the wall of said base member 10, directly below the ledge or rim 18-thereof. The number of said recesses, in any case, corresponding with the number of signal lenses mounted in the lantern body'. i

The illuminating medium may be of any type. In the present instance the samey is shown'as'of the electricallyv operated type,

vand to vthat end the base member 10 is providedwith a-socket -11,'to receive an electric lamp 12. The current isl supplied byconductors which 'pass through a eompressible Ypacking 13a disposed in a stufiing box 13 in the bottom of the base member 10. The lamp V12 is controlled by. a switch actuating member 14 which also passes through said bot-V tom. Y

The manner of operation of the signal lamp -will be largely vobvious from the foregoing description. It need merely be noted that to Vadjust the lantern body y19, to display'any one ofthe signal lenses mounted therein, the spring-pressed plunger or pin 30 is first drawn outwardly to release the inner end thereof from its engagement with-the recess 32 of the base.v The lantern body may then be rotated upon the base, and when-the same is caused-to assume the desired position the inner end of the plunger 30 will automatically enter the appropriate recess 32 necessary to hold the lantern body to the position required to display the desired signal light.

To detach the base member 10 from the lantern body 19 it merely becomes necessary to lirst release the locking plunger 30, and then rotate the'lantern body 19 until the lug 28 is brought into register with the recess 29 in the ledge or rim 18 of the'base member, whereupon the lantern body may be tilted and released of its engagement with the base.

It is to be noted particularly that by means of my invention I am enabled to provide a signal lamp consisting of but two `essential parts which maybe easily and conveniently joined togetheror separated. As a result of Y.

the construction and arrangement of said parts, the providing the base member 10 with means rigidly supporting the entire signal lamp permits of the ready/adjustmentV or rotation of the entire lantern body withre.

spect to said base member when changes in the signal lights are to be made. f
