BENJAMIN F. LOLLIS, OF BRWYN, LLINOIS, ASSIGNOR OF ONE-HALF TO FLATH, 0F CHICAGO, 1LLINOIS,
Application led May 14, 1923. Serial No. 638,777.
T0 all whom t 'may concern:
Y Be it known thatv I, BENJAMIN F. LoLLrs, a citizen o' the United Statesa and a resident of Berwyn7 in the county et Cook and State of Illinois, have invented certain new andk f vision of means whereby thesignal lamps may be adjustably mounted on the supporting post or stall of a semaphore so as to permit ready and ample adjustment of the lamp in a lateral and vertical manner in order that the raysoflight may be directed .or thrown in the desired manner. or direction relative to the track so as to provide proper signal for the crew of the locomotive.
A further object of the invention is to provide an adjustable support which will not only permit the adjustments to be readily made but which will at the same time enable the adjusted positions ofthe lamp to be maintained.
The objects and advantages of my invention will be more readily comprehended from the detailed description of the accompanying drawings wherein;-
Figure 1 is a side elevation of a signal lamp with my improved support for securing the lamp to the stall` or pole of a semaphore; a portion of the statt' and spectacle casting being shown.
Figure 2'is a vertical sectional view taken on the line 2 2 ot' Figure 1 looking in the direction of the arrows.
Figure 3 1s asectional bottom pla-n view taken on the line 3*--3of Figure 2 lookingA in the direction of the arrows.
Figure t is a cross sectional viewV taken on the line 4 4 of Figure 2 looking in the direction of the arrows.
Figure V5 isa detail sectional view taken substantially on the line 5 5 .of Figure 2f looking inthe direction of the arrows.
Figure 6 is a perspective view7 looking upwardly7 orp ka portion of the lamp housing,
showing an adjustedposition of the bracket i and lamp housing.
My invention relates more particularly to signal lights employing incandescent lamps and which, Jfor the sake oic cost and maintenance, use comparatively small filaments and therefore necessitate the accuracy in placement and adjustment in order to obtain the maximum efficiency and the required results.
The lamp comprises a suitable housing 10 apertured to receive the bulls eye or lens 11; the housing being provided with a suitable lamp as at 12 provided with the lines or wires 13 which lead to terminal posts as at 14, which in turn receive the supply line 15 which passes through a suitable opening. as at 16, in the bottom of the housing 10. VThe lamp 12 is carried by a bracket 1'? adjustably mounted on an insulator block 18 sej side ot the cover or hood shown provided with a hasp 2O hingedly secured thereto and adapted to it over the staple 21 secured to the housing` proper and which receives a suitable lock. As the general lamp construction forms no pa-rt of my present invention, further detailed description thereof need not be entered into.
rlfhe bottom of the housing 10 is mounted on a bracket member 22, preferably by means of boltl and nut, with the bolt extending through the housing bot-tom and the bracket as shown. at 23 in Figure 2. The bracket member 22 is disposed laterally in a direction transversely of the housing 10 and somewhat beyond one side thereof. where the bracket member terminates in an upwardly disposed portion or leg 24. The upwardly disposed leg or portion 24 is shown provided with a threaded stud-25. Ureterably -termed integral with the upstanding leg 24@ and this stud is intended to be disposed through a suitable aperture in an upstanding leg or portion 26 ot second bracket member 27. The threaded stud 25 is of length suiicient to extend entirely through the opening in upstandingleg 26 et bracket member 27 to receive a nut and washer as at 28, and thev contacting` surface of the stud 25 and upstanding leg-26 may be sightly serrated as at 29 in order that a more' secure gripping relation between the members may be provided.
The bracket member 27 is preferably provided with an elongated slot as at to receive a pair of bolts 3l whereby the lower bracket member 27 is adjustably secured to the supporting arm or bracket 32, which 1sV suitably secured to the stati or poley 33 of a semaphore as shown in Figure l. The slot 30 is preferably disposed lengthwisel of the4 horizontally disposed portion of bracket member 27, see Figuresi2 andi 5',.\vvhile` the ing permissible by reason of the slot 30- andreadily accomplished upon loosening the nutsfoil bolts 3l; while the adjustment of the lamp in its position relative to the -spectacle casting, namely towardor away from the casting, A'may be accomplished through the slot 34 upon unscrewing the nut of bolt 231. At the same time it is apparent that the housing l0 may also be swung laterally about the pivotal point 23'to obtain the desired horizontal or lateral disposition ofthe lens. Y
Where vertical adjustment oit' the lamp is necessary by reason ofV grade or elevation in the right of way, it is apparent that such adjustment, to Vdirect the rays of light either in an upward or down direction relative to the horizontal, may be accomplished by 'loosening clamp nut 28, which will permit bracket member 22 with the lamp to be swung or moved through the arc ofV a vertically disposed circle. With my improved support, it will be seen that accurate adjustment and positioning of the signal lamp, to meet diilerent condi-tions encountered, may be readily accomplished Vand that adjustment may be positively maintained..
As an illustration'of the manner ofadjusting the bracket members relative toV each other andalso anv adjustment of the lamp housing relative .to the bracket, I show an upward tilt of the lamp-housing in the fragmentaryl perspective view, Figure 6 (the attaching bracket` 32 being omitted) where the member 22 isshown swung forwardly through a vertically disposed are about the pivot pin or stud 25, while the lamp-housingl() is likewise shifted slightly toward the right aboutV the axis of bolt or pin 23,
thus directing the rays of light at an angle to the horizontal plane of'bracket member 27 and at an angle to the vertical plane of the supportingpost or stati of the semaphore.
I have shown what I believe to be the simplest adaptation of my invention which Y has beenl described in terms employed merely as terms of description and not asterms of limitatiomas structural modifications are possible and may be made without, however, departing from the spirit of my 1nvention. Y
What I claim is 1. A signal lamp support comprising a member adapted to be secured to a supporting' post or sta and to extend laterally therefrom, an angular bar adapted `to be secured to said member, one end of said bar being arranged to extend upwardly, a second bar having a bent end adapted to extendflush with ythe upper portion Vofthe upwardly extending end of the angular bar, means whereby said ends of the two bars are pivotally clamped together and the second bar permitted to swingv through the arc of a vertically disposed circle, in combination with a lamp housing pivotally secured tothe free end of said: second bar and arranged to permit adjustment transversely of the bar. i
2. A signal lamp support, comprising a member adapted to be secured-to a supporting post or staii and to extend laterally therefrom, a pair oit horizontally arranged bracket members, each having a vertically disposed portion, with the vertical portion of the one member shorter than that of the other, said portions being arranged in lapping relation and pivotally secured together with the horizontally disposed portions of the'two bracket members in vertical spaced relation, one above the other, so as to permit vertical swinging movement of the upper member relative to the lower, means whereby the upwardly disposed portions oi' said bracket members are clamped in adjusted posi-tion, means whereby a vlamp housing is adjustably secured to the upper member of said pair of bracket members and horizontal turning of the lamp housing permitted, and means whereby the lower member of said pair of bracket members is, adjustably secured to the first mentioned member, so as to permit movement of the lower bracket member toward* and away `from the supporting post or staff.
3. A signal lamp support, comprising a rigidly held bracket secured to a supporting post, a pair of bars each consisting of a horizontally disposed port-ion and a verticallyv disposed portion, the bars being so arranged that the horizontally disposed portion of the "one is spaced apart and above the horizontally disposed portionw'ot` "the other, with the vertically disposedk portions of both bars arranged in lapping relation and pivotally secured together to permit the upper bar to swing through the are of a verticallydisposed -circle'-7 thel horizon-V tally disposed portion of thev lower bar loethrough said transversely disposed slot of ing slotted lengthwise thereof for the pasthe upper bar. sarge of bolts whereby said lower bar is adjustably secured to the first-mentioned BENJAMIN F.
