, This invention relates to railroad crossing signals.

vAn object sion of a devlce for displaying laV warning signal at a railroad `crossing which is auto-k matically positioned through thefoperation of a mechanismactuatedby thek moving train beforeit reaches the crossing, the signal betuated by the wheels'otl the train before said ing moved to an inoperative positionby" themoving trainA after the crossing has been passed.

rA furtherobjectlof theinvention the" 'provision of a vsignal adapted to be automatically displayed as a warning to trame at' arailwaycrossing and which is moved to an operative position through a mechanism actrain reaches 'the crossing. A similarmechanism, bu 'iieverselyac tuated, being adapted to cause" eSignal to be moved to anglinoperative position after the train has moved beyond therailway crossing.` j y This invention will be V,best funderstood from a consideration of the following detailed description, in view ofthe accompany-y ing drawing forming-a part of the specification nevertheless7 it is f to ,be understood that the invention is not confined to thedis-r closure, being susceptible of such changes ,and modifications which shall denne noma yterial departurefrom the salient features ofthe invention as expressed vin *theA ap pended claims.

rReferring more particularly to the drawn ings, vdesignates a'road bed passing over a railway having railsll and cross ties 12.4 The signal shown at 13 is slidably mounted in posts 14 and 15 adapted to be normallyV rocked VWithin ay housing 16 carried by the upper ends of the post.' The signal isy shown in its operative position lfor warning the public When a train is approaching', the .signal being supplied with indicia tothat effeet.l A housing may be placed at the rear of the invention is ythe provi-y aside view showing the signal of the signal and provided with lampssofl that said signal will be illuminated at night when the same is placed in an operative warning position and contacts may be carried bythe moving signal yfor engaging the contactV forming terminals .of an electric'cir.

cuit, wherebythe lamps ymay be automatically lighted kwhen the signal is moved .to its operative position. .The signal may Vbe transparent through ywhich the light raysl are projected or the lamps maybe located in a convenient position opaque signal.y

'A The signal arm 17 pivotedvat'18 tothe top of the signal and also pivoted-at 19 on thepost-15 and rigid'with an arm 20,' the arms 17 and 18 `forming a bell crank lever. 7A link 21 is pivotally connected at its ends, respectively,

`with the arm 20 and a'lever 22-rigid with a shaft 23 mountedin bearings 24 onla post or bracket 25. Theshat 23 also is provided ,with an arm 25a having the slot 26v into which is inserted a pin 27 lconnected with the upper free end of an arm 28 rigid with Vthe shaft-29. The shaft is mounted in bear ings 3() carried by al second block, 3l extendfor illuminating an,r

is immediatelyl actuated by an ing downwardly from the shaft 29 and rigid therewith is an arm 32 providedwith a;slot 33 receiving apin 34 carried by aconnection '35. The connection 35 secures the links 36 and .37 together. The links '36 and 37 may 35 may be a sleeve slipped onto the rod and securedto the same in any approved many nel'. e l

The elements designated by the numerals 17'to 37 inclusive, forni the yconnecting means between the signal 13 and the mechanism ac-` tuated by the train for causing proper positioningof. the signal to warn the public.

t An actuating mechanism including a. trip-y ping means whi'ch comprises afpair of bars' 38 and 39 pivotally connected together atA 40 beI formed of one piece and theconnection n and have Han 'es 41 adapted .to be engaged t n by a iiange yo the wheels of, the tra-ins for depressing the inner elevated ends of said bars and these bars' at their outer 4endsy rigidly connected with the shaft and has aninclined portion @adapted to be engaged by the underface of a flange 41 of the bar 39 when said bar is depressed. A link 50 connects the lower end of 'the arm 47 with the outer end of the link 37 as shown at 51. ff

A mechanism is also employed at the opposite side of the crossing 10 for causing the signal to be moved to an inoperative position after the train has passed. This mechanism is actuated by the moving train after the rear end of the train has passed the crossing. This device is similar to the actu;

ating mechanism'of the signal and comprises a pairof bars 52 and 53 pivotally connected at their inner. ends as qshowin Yat 511i.- These bars fare flanged as l'shown at pand 'adapted crossing 10k will move over the bar 39 forc-v ing said bar downwardly and likewise bar 38.

'f The flange 41 of bai-39 yengages the free end 49 ofthe toe 4S, pscillati'ng said toe and rocking the arm or lever '47 ina direction indicated bythe arrow in Figure 3. The outer free end of the lever pulls on the links 50 and 37 thereby moving the' arm or lever 32 to the positionshown in Figures 2 or al so that the arm 28 is moved to the left, oscillating the lever 22 in a direction indicated by the arrow in AFigure Il. As the outer end of theV lever 22 is moved downwardly, the lower end ofthe arm 20 has been moved upward ly, depressing arm 17 and lowering the signal .13 to view as `a warning. Y

After (the train has passed lthecrossing 10, the wheels will come in contact with the bar 53 and thereby depressing the bar 52 and toe 56. This movement rocks shaft l57, thereby moving lever or 'arm G0 as indicated by the arrow in Figure 2 causing link 36 to be moved Vto the left and reversely rocking arms 32 and 28, this causes the upper end of the arm 22 to be -moved in the direction which is opposite to the direction indicated by the arrow in Figure 4, whereby vthe arm 2O is rocked towards the post le, thereby elevating `arm 17 and moving the signal '13 into the housing .16.

It will be noted that there are no springs, cables or pulleys Vemployed in the 'mechanism actuating the signal and only aV right and left end trip are required upon opposite .sides of thel railroad crossing 10 and connected by links which are of suihcient length 'to allow the train to 'pass between the trips so that both trips will not be actuated at the same time. All of the operating elements are inclosed ina' housing, except the tripping device which comprises the pivoted bars 38 and 39 and` 52 and 53.
