' Be known that we, (l) STEPHEN Kiwa vand (2) PAUL Tilman, (l) a citizen of the f-.United States of America and (2) a subject yfot the Emperor of Austria-Hungary, resid- A "ting at Biighamton, in the county of Broome `and State of New York, have invented certain new and useful mprovements in Automatic Gates for Railway-Crossings, of which train is approaching thereon while the designed mechanism likewise automatically opens .the the highway crossing.

A still further object is to provide a trip actuated gate member in connection with a railway crossing whichmay be connected to any desired number of' distantly positioned similar gates for the simultaneous actuation thereof.

, With these general objects in View and othersthat will appear as the nature of the invention is better understood, the same consists in the novel combination andarrangement of parts hereinafter fully described, illustrated in the accompanyingr drawings and pointed out in the appendedl claims.

ln the drawings forming a part of this application and in which like designating cl'V racters refer to corresponding parts throughout the several views, Figure 1 is a plan view of a portion 'of a railroad track adjacent the highway. crossing and prov'ided with the present invention, two of the gates being shown in their closed positions. Fig. is a siderclcviition.thereof with one of the gates illustrated by dotted lines., in its open position. Fi' .,lfisa View of the mechanism casing with onesido removed aud in section l/ongitu/dinally; of the connecting Lube casing! with the gate brokenv away and in its open position. Fig. 4f is a similar view with thel parts arranged with the gate gates when the train has passed y closed. Fig. 5 is la similar View adjacent one side of the casing and illustrating the electric switch for the signal lights1 the gate being open. Fig. 6 is a transverse sectional view of the mechanism casing with the gate open. Fig. 7 is an enlarged detail View of the releasing trip mechanism. Fig. 8 is an enlarged detail view of the operating dogof the device. Fig. 9 is a side 'elevation' wit parts of the elements broken away of thev Wheel operated track trip, the same being shown in its inoperative elevated position, Fig. 10 is a similar view illustrating a wheel as operatively positioning the track trip in itslowered position. top plan View of a portion of a rail provided with the track trip, the tube casing for the operating cable being shown in horizontal section. Fig. l2 is a transverse sectional' View of the mechanism illustrated in Fig. l0. Fig. 13 is a modified form of connecting means between lthe track trip and the connecting cable. \Fig. la is a detail view partly in top plan and partly in section showingthe operating means for distantly positioning gates. Fig. l5 is a top plan view of the releasingtrip illustrated in Fig. 7. Fig. 16 is a 'top `plan View of the operating dog illustra-ted in Fig. 8. Fig. 17 i is a central longitudinal sectional view through one of the gates illustrating the signal Vlamps positioned. therein. Fig. 18 is a side elevation thereof and Fig. 1f) is a top plan view showing a plurality of tracks and highways cach' provided with gates automatically actuated by a moving train upon single one of the tracks. Fig. 2O is an enlarged inside view of a portion of the casing showing certain details of constrction, and, Fig. 2l is a sectional- View taken through Fig. 2O.l

Referring more in detail to the drawings, it will be noted that the devicevbroadly consists in positioning the gates 2O adjacent the oppositev sides of the road bed of a railway suoli as 2l and' in providing means for automatically closing thc said gates to thehorizontal position across the highway such as 22 when a train is approaching suoli highway upon the track and moving in the direction indicated by the arrowr inFig. 1, it being also intended that such train shall automatically return the gates to their open or `The operating mechanism for each gate employed is housed within a similar easing Q4 positioned adjacent the railroad track and at one side ot the highway which crosses the same, the' said easiiigs preferably having aourved roof for rendering the better adaptedfor shedding storms. An operating shattQll is joiirnaled iii the upper portion of the easing 24. and at one end thereof projecting exterior-ly the easing and upon which end the gate 720 is rigidly secured. v

The gate 2O is tubular in form beingprovided with an inner bore'QY. llithiii the bore 27,4111 electric signal lamp is positioned which is adapted to be constantly burning in the night time and during' the day desired and being' viewable through a white glass 29 iii the 'outer tace of the gate.A An- .other similar lamp 3l) is positioned within the bore 27 and is .viewable through a green glass ill in the same lace et the gate and is electrically Conner-ted with a stationary oontact 32 and a movable Contact 33 mounted upon the inner tace V4of an end wall 34 o'l' the easing' 2l, l third signal lamp 35 is likewise positioned within the bore 27 and is viewal'lle through a red glass 36 in the correspondingY .tace of the gate while the lamp 35 is-in electrical connection. with a stationary switelin'ieniber 37 and a' movablel switch Imember 38 carried by the end wall Silat a point slightly beneath theeontaots 32 and l2-3 heretofore referred to. Vlhe electrical connections between the lamp 35 and the fixed Contact 37 and movable Contact 38 consists respectively of the

wires

84 and 85 while similar connections are afforded be tween the lamp 30 and the iixed Contact 82 .and movable Contact 2li-l by the respective wires 83 ard S2. The wires 80 and 8l are provided iii the cable fili for allording the lamp Q8 with a permanent supply ot electric current from a suitable source such as a battery (not shown). Il finger l0 is rigidly secured to the power shaft QG iiitorioily ot the easing 2l and is adapted to engage the nio'vable switch member upon a down.- ward closing movement ot the gate and thus close the electric ,switch ol the `green signal lamp 30 when the gate is `siibstantially.half Closed while thereafter. the linger ll() engages the movable Contact and i'loses the electrical switch tor the red signal lamp ries tho saine in itsl closed position. Each` ol' the n'iovable switch iiieinliers and 38 respectively are provided on their opposite sides with springs Ill which allow a slight returii movement oi the. movable switoh members after engaging the bottoms of 'the

hniie switch sockets

32 and 37 respectively while the opposite or upwardliy positioned 'springs 41 of each of the movable switch members will engage an adjacently posi- 'tioned stop 42 upon the wall 34 and thus return said movable switch members slightly downwardly after having been completely opened yupon the return upwardly swinging' movement ot' the finger 40. By this arrange- 30 and 35i, arid that the said slight return movements of each'of the movable .switch members places such members in the line of travel of the linger 40 for Contact and -actiiation upon its next movement.

'lhe power shaft 2G is provided with a eirciilar disk 43 secured thereto and preferably provided with a rubber covering and being in constant engagement with the annular operating portion 44 of an alarm bell carried within the easing. It rwill be see'n that hy'this arrangement, upon any movement of the gate and the accompanying revolving of the shaft 26, the alarm belli-35 will be actuatedj the operation of such bell being similar to the tire contacted bi'eycle bells now commonly employed.v A gear 47 is secured to the power shaft 26 and -is in mesh with a smalle/i4 gear 48 positioned upon a transversely joi'irnaled shaft 49 within the easing 24 and beneath the. power shaft 2G. A drum 50 upon the shaft 49 is provided with af oord 5l secured thereto and adapte-l to lie woundthereon while a weight 52 is attached to the free end of .the said oord. The position of the gate being horimintalwhen closed as illustrated in Figs. 1 and L the cord 51 is then arranged to he in' its wound position upon the drum 50 and with its weight 52 elevated as best shown in. Fig. 4. With the `gears 47 and 4S unrestrained, the lielt of the weight 59. is sufficient to turn the gears and the power shaft 26 thereby elevating the gate to its open position.

One of the rails 53 of the track is provided with a ife'rtical' opening 54 therethrough adapted to slidably receive arod` 55 upon the upper end otwhioh a head 5G is positioned and adapted to move `vertically within a socket 57 of the rail tread. it being noted that a plurality of rollers 5S are pretv erably provided projectingl from the upper surface of the head 56 and adaiited 'for eontaot by the passing: wheel 5l) ot' a train and resulting in placing thel trip member so i'orinzii in its depressed position as illus'- f-trated in Fig. 10.

The easing is provided-with gipposite openingen` (l0 adjacent the bottomitb i` t and io which openings voppositely faillit nding i'io Liao, ies

tubular casings 61 are attached, each of the loer 62 extending beneath the adjacent tracir seid Casings- (i1 having an angular end inemrail 53 and in alinement below the track trip 5S and 111 thereof. l

Each extension 62 is provided with a'cirn cular disk. 93 journaled therein and connected by a linlt 9st with the said trip rod 55. The disk 93 has a peripheral groove 95 Within which is secured one end of a cord 9C, which cord passes over a pulley 97 at the connection of the casing G1 and its'extension 62 through'the casing 61 and after passing over and then extends the entire length a pulley 98 has its free end secured to the lower side of the operating clog 99, which latter is pivoted to a bracket 100 upon the inner side ot the casing 24. Upper and lower springs 101 are mounted upon the Abracket 100 and engage opposite faces ot the dog 99, normally retaining the same in a suhstantiaily horizontal position and hetweeny adjacent ones` oi the'.l teeth of the power gear 4:7. f

A releasing'trip 102` is mounted within brackets 103 carried by the casing 2% and is normally inwardly projected by an encircling spring 104 so as to engage between the adjacent Vteeth of the gear 1J. A' connectin'gcord 105 is secured to the dog 102 at one end and extends over upper and

lower pulleys

106 and 107 respectively of lthe casing and has its opposite end attached to the cord 96 at a point slightly within the casing end of the tubular member 61.

Vith the elements positioned as illustrated in Fig. 3 and with. the gate in its open vertical posit-ion. the automatic operation ,of the device including the gate 'will be apparrent. As each succeeding wheel of the'train strikes .the track trip during a passage of the train over the rail it will be evident that the trip rod will he rapidly reciprocated in a vertical direction7 the car wheels effecting the depression thereof while the extension spring 108 acting to ,promptly re- Wardlyoer the fncxt ,turn the trip to its uppermost position.

llachdownward movement of the trip nod 55 gives-a partial rotation to the disk il?, thus slightly winding the cord 9G thereover and imparting a pull upon the cord SH2 and drawing downwudly the operating dog 99 which hy its contact with thi adjacent tooth 109 ot' the gear e? results in a slight turninpr oi' the gear as well as its poner shaft Q13 and upon which the gate is secured and with which it is thereby turned in itsclosing"A movement. The releasing oi the track trip by a passing ofI the wheel thereoi'er slarlens the .oord flf and allows l i i x Y theiowerspring '101 to return gne dog to its normalprlsition, the said dog ratchetiufg up- The operation oi' the tooth o said gear i?. l 4

that described whentrip being the same as upwardly positioned f ever any fil'vfci passes thereover, it will be seen that the passing of the train causes the 'operating dog to engage each of the succeeding teeth of the .gear 47 until the inter-.- rupted gear portion 110-is reached and at which time the gate will he lowered as shown in Fig. 4. During each tooth engaging movement of the dog 99, the releasing trip `102 is' actuated for releasingftl'ie gear 47, such movement of the trip being effected by reason oi tho pull exerted upon the cord 105 whenever the cord 96 is pulled and to which cord 9G the said coi-(i105 is attached7 the trip 102 yinnnediatcly returning to a locking position and engaging the next succeeding tooth oic the gear 48. l i

From this detailed description the operation of the device will loe evident so far as the automatic closing of the gate hy the track trip is concerned as well as the inanner of sounding the alarm bell 45 ,during any movement. of the gate and also the automatic control of the electric signal lights 3() and 35. v

A similar tripping member 111 is positioned uponfthe rail 53 at a point upon the track on the opposite side of the highway 4trom the gate closing trip and the construction thereof as Well as its operation being identical to that heretoforedescribed, `it will he only necessary to note that the trip 111 is designed for the purpose ot' pulling the cord 112 upon each Contact oi' a wheel with the said opening trip 111. The trip 56 being positioned first in the path of travel of the passing train, is adapted to close the gate by pulling the cord flo' while the trip 111 being contacte-dr by thesarne train after the train has passed over the highway. is adapted to release the trip 102 by pullingv uponI the cordl 112 and thus allowing the weight 52 to return the gate to its open position als heretofore referre'd'to, the cord 112 being attached to the releasing trip 102.

The releasing 'trip 102 is slidahly mounted within lnfackets 103 carried hy the casing 2t and is spring-pressed by means of the encircling spring 104- to normally hold the trip in engljagenient with the adjacent teeth ol the gear 47.

The gato 20 when closed is adapted to have itsl free end rest within a Ushaped bracket 115 positioned adjacent the track while the gate at its og'iposite and shorter end is providedwith a plurality of weights 11G acting as a coui'iterl'mlance in assisting to return the gate to its open -vertical position. l

ln Fig. 13 thereA is illustrateda modified torni of trip connecting 'means which consists in connecting the'trip rod pivotally with aln angular rocker arm 117 and having the coild 96 secured to the other end of said srocker arm and itwill hee/vident that either 130 f L weones 'K of 'these forms of connections may he em# ployed with either the eiosing trip 56 or the opening trip lll. of. the device.

thereinto. A. tubular housing 120 is preferM ably proxr-ided for the shaft d8 and is ,se-- cured between the said casings.

A sprocket Wheel 121 is secured upon the shaft 49' oi each casing and has a sprocket v chain i322 extending thereover and also over a similar sprocket wheel 123 mounted upon.

the extended end of the shaft 11S within the casing and in vertical alineinent with the said wheel 121. nly that one of the casings 24. to which the trip cords communicate is required to he supplied with the releasing trip 102 or the operating dog 99 and all of the other elements within the resj'lective easings 24 being identical, it will he seen that the movementsoi' the power shaft 2li and consequently the gate carried. therehy will he uniform. .in this manner, the gates :20 .may he operatively positioned with respect to the track and across the highway as shown in Fig. l. and simultaneously closed and opened hy means or' the closing trip 56 and opening trip lll respectively'.

As illustrated in Figs. M- and lil, a casing iZ-lmay he supplied i'or one gr* llthe latter being actuated directly hy the closing and opening trips as heretofore descrihed. The opposite gare l2@ may he similarly actuated while other gates lf2? and, l2@ upon opposite sides oi' a neighboring track 122 are simultaneously' opcratwl hy similar connections positioned within a 'tubular casing 130. Other gates 130 and 155i positioned adjacent another highway may he similarly operated by a sprocket chain 1232 connecting the operating mechanism of said gates 13 and 131 andthe power shaft liZ-l within the said casing 130. y

W'hile the forms of the invention herein shown and described are what are believed to he preferable embodiments thereof, it is nevertheless to he understood that minor changes may he made in the form, proportion and details of' construction without dei parting from the Spirit and scope of the inventionas set forth inthe appended claims. What is claimed as new is z l. A crossing gate comprising in combination' with a track rail having spaced per for-ations therethrough, of normally elevated wheel engaging trips vertically movable within said openings, a casing positioned adjacent the track, a power shaft within said casing, a gear securedto shaft, a gate secured *o an outwardly projecting end of said shaft, an operating dog pivoted within said casing and engaging the teeth of said gear, releasing means within said casing engaging said gear, operative connections between said dog and releasing means and one of said trips whereby said gear'and power 'shaft and gate are turned in the gate closing direction during the passage of car Wheels over the said trip, connections between said releasing means and the other one of said track trips and means for turning the said gear in the gate opening direction upon a disengagement of said releasing means.

Q. A trip device comprising in eomhination with a rail. having 'a xv'ertical opening therethrough terminating at its upper end in a socket open at the tread portion of the rail, a rod slidably movable within the said opening, a convex head upon the upper vend of the said rod and movahly positioned within the said socket, a plurality of rollers journaled in the said head and projecting upwardly therefrom, a disk lhaving a peripheral groove journaled beneath the said rail, a link pi'votally connecting the lower end of the said 'rod with, a radial point upon the adjacent face oi the said disk, automatic projecting means for the said rod whereby the upper faces of the said rollers are normally resiliently supportedahove the rail tread and a gate actuating cord having one end thereof positioned and-secured within the said disk groove. f
