DANGER-SIGNAL.

Specification of Letters iatent. Patented Apr. 8,1919.

Application filed October 29. 191$. Serial No. 260,132.

To all whom it may concern:

Be it known that I, NOAH A. AREL, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented I provements in Danger-Signals, of which the following is a specification.

This invention relates to automatic signals for railroad crossings and the like and the principal object of the invention is to provide mechanical means operated'by the train for displaying a signal at the crossing to indicate that a train is coming.

Another object of the inventlon is to provide a device of this characterwhich is simple and durable in construction, reliable and efficient in operation and one which can be manufactured and placed upon the market at a minimum cost.

The invention also consists in certain other;

features of construction and in the combination and arrangement of the several parts,

to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, ref-' erence will be had to the accompaying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view of my invention.

Fig. 2 is a side view with parts in section.

Figs. 3 and 4 are detailed views.

Fig. 5 is a cross section through the'upright and shaft showing the means for hold in the parts in inoperative position.

11 these views 1 indicates the track and 2 the crossing. Adjacent the crossing I locate an upright 3 suitably supported on a base 4:- The upright 3 is of tubular form and the shaft 5 passes therethrough. The end of the shaft is provided with a crank 6 and its upper end projects above the upright and has secured thereon an arm 7 .which contains the I legend Stop-Danger or similar words. A pair of shields 8 is also secured to said shaft at its upper end and a lamp '9 is placed between said shields and is suitably secured to the upright 3. A wheel 10 is rotatably mounted at the upper end of the upright 3. This wheel issupplied with ball bearings so that it will revolve by its own momentum after being is engaged by the dog 12 carried by'the new and usefullmstrikers 13 which are adapted tocontact with a bell 14 carried by the upright; The up-I right may be braced by the ladders 15. I

The crank 6 is connected with a pairof I shaft. The: wheel also carriesa number of chains-,pass'over the guiding rollers 18. The

Eachrod is connected with an oscillating member 19, wh1ch 1s pivoted" intermediate its ends at a suitable point along the track so that ltWlll be struck by a part carried by thetrain. Thiswill cause the rodto slide and through means of the chain 17 will partially rotate the crank and thus turn the shaft so as to place the words on the arm in rods 16 are suitably mounted along the track and extend in opposite directions. I 7

a position where theyomay be seen by any one passingalong the crossing 2. Atlthe same'time the dog engaging the rack will spln the wheel 10 and thus sound the alarm.

The shields 8 will be moved so'as to expose of. the Weighted arms 20 connected with the chains and the'weight 21 connected with the roller. It will beseenthat one rod will not the lamb. so that a signal may be given at- I mght. The parts are returned to. normal position after. the train has passed by means arm 6. This weight 21 is connected with the arm by a cable which passes-overasuitable v interfere with the other as the chains will simply slack while one rod is being moved. It is thoughtfrom' the. foregoing descrip tion that the advantages andnovel features of my. invention will be readily apparent.

I" desire it to be understood that I may. ,make' changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of theappended claim. a hat I claim is; V

A device of the class described comprising an upright, a shaft rotatably supported thereby. signal means carried by the'shaft, a wheel rotatably carried by ,the' upright,

strikers on'said wheel, an annular rack "on said .wheel, a dog on the shaft engaging said rack, a bell on the upright adapted to be en gaged by the strikers, a trip 'ldevice located adjacent the track and adapted to be struck by partofthe train and means forconne'ct; 1 ing said; device with theshaft. started. The wheel 7 is provided with the annular rack 11 which In testimony whereof I affix my signaturei NOAH A. ABEL. j
