SIGNAL-CONTROLLING MEANS FOR BIAILWAY-GBIOSSINGS.

1,247,477. Original application filed October 8, 1915,

To all whom it may concern:

Be it known that I, HARVEY J. YAGER, a cltizen of the United States, residing at Seattle, in the county ofKing and State of Washington, have invented certain new and useful Improvements in Signal-Controlling Means for Railway-Crossings; and I do herebydeclare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to signal controlling means for railway crossings and other intersecting rails and the present application is a division of an application filed by me October 8, 1915, Serial #554,840.

The object of thepresent invention is to provide simple, practical and efficient signal controlling means for railway crossings and other intersecting rails and to enable an oscillatory or vibratory member of a railway crossing to close a circuit and to operate a signal for indicating that the said oscillatory or vibratory member is in one position and for closing a circuit and operating another signal when the vibratory or oscillatory member is in another position, whereby the said signals will indicate the position of the movable parts of the railway crossing.

. A further object of the invention is to pro vide signal controlling contacts or mechanism of this character designed for use in connection with rotary frog members and capable of indicating the position of the frog members which form a continuous tread for one track and bridge the grooves or spaces of the intersecting track.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departin from the spirit or sacrificing any of the a vantages ofthe invention.

In the drawin s Figure 1 is a plan view of a railway cross ing provided with signal controlling contacts constructed in accordance with this invention.

Fig. 2 is a vertical sectional view taken longitudinally of one of the pairs of oscillatory arms.

Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2.

Fig. 4 is a vertical sectional view through one of the corners of the crossing.

Fig. 5 is a detail sectional view of one of the oscillatory arms.

Fig. 6 is an enlarged detail view of one set of the contacts.

Like numerals of reference designate corresponding parts in the several figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention as applied to a railway crossing, 1 designates rails arranged in pairs at right angles to each other and connected at their ends to corner bearing plates 2, connecting the rails 1 and also connected with outer rail sections 3. The crossing is provided at each of the rails with a flangeway or groove 26 and each of the corner plates is provided in its upper face with a cylindrical bearing recess or socket 34E receiving a circular rotary frog member 35 provided with a flangeway or groove 36 adapted to be arranged in alinement with the flangeways or grooves of the intersecting rails to form a continuation of the grooves or ways for safely guiding the flanges of a wheel at the crossing. The frog member is provided at opposite sides of the groove 36 with tread faces 37 which are arranged in the same horizontal plane as the tread faces of the heads of the rails. As said application the corner bearing plates and the rotary frog members are adapted to form a continuous tread surface and a continuous flangeway or groove at each intersection of the rails so that all hammering of the wheels of a car or the like at the intersecting rails is eliminated.

Each of the rotary frog members is pro vided with a centrally arranged descending stem 39 on which is'mounted a gear element 44. The gear element 44: of the rotary frogs are actuated by oscillatory arms or bars A8 and 49 disposed diagonally withrelation to the crossing and provided at their outer ends with gear elements 50 and 51. The

ear elements 50 and 51 are substantially in the form of racks,the teeth of the gear element-50 of the oscillatory bars arms 45 extending outwardly from enlarged terminal portions of the said arms or bars. The other set of arms 49 are provided intermediate of their ends with deflecting bends 52 which arrange the body'portions of the said arms 49 below the plane of the other arms 48 and enable the said arms 49 to extend beneath the stems upon which the coacting gear elements are mounted. The arms or bars 49 are provided at their outer ends beyond the stems with flanges 53 having inwardly projecting spur teeth constituting the gear elements 51. The gear elements of the stems-contiguous to the gear elements 51 are arranged reversely of the gear elements of the other stemsin order to mesh with the inwardly projecting teeth of the gear elements 51 of the arms or bars 49. This arrangement effects a rotary movement of some of the frog members clockwise and other of the frog members counter-clockwise when the arms or bars 48 and 49 are oscillated in the same direction.

The inner ends of the oscillatory arms or bars; are mounted on a vertical rotary support. or pivot 59 having upper and lower journal or pivot portions 60 and 61 and set in a bearing 62 of a bottom plate 63.. The upper journal or pivot portion 60 is mounted in an opening 73 of an upper bearing plate 7 4 which is bolted or otherwise secured to an approximately rectangular support 76 bolted or otherwise secured to the bottom bearing plate 63. The oscillatory arms or bars are actuated by the means of electromagnets 99 and coactingelectromagnets 100 arranged and operating as set forthin the aforesaid application and as the. particular construction of the railway crossing and the means for actuating the same form the subject matter of the aforesaid application further description and illustration thereof aredeemed unnecessary. V

Mounted upon the inverted U-shaped support86are contacts 109 and 110 consisting of plates arranged: in pairs and mounted in insulators 111. The insulators 111 are secured in suitable supports or brackets 112 of approximately Y-shape composed of. spaced sides and a connecting portion from which depends a centrally arranged stem. The stem pierces the top of the support 86 and is threaded for the reception of a nut as clearly shown in F ig. 5 of the, drawings. The contact plates or pieces 109. and 110 which are designedto be connected with signal light wires 109 and 110 are arranged in pairs at opposite sides of thesupport and the contact plates 110 which are of greater length than the contact plates 109. are resilient and are adapted to be sprung into engagement and electrical contact with the plate109 whereby one of the signal light circuits will be closed when the oscillatory depending sides located'at the side edges of the thickened portion of the oscillatory bar I or member 48 and the said sides are adapted to flex thecontact 110 and force the" same into engagement with the I contacts 109. When the oscillatory armsor bars are moved in one direction by the energizing of the stationary elec'tro-magnetsi99 and the movable electro-magnets 100 the latch bolts are withdrawn by the energizing of the latch operating magnets 91 and as soon as the latter are deenergized'by the. cutting off of the current the spring operates to force the latch bars upwardly into their' engaging position. j v
