nerrnoen cnossnva Application led May 17',

To all fw/iom t may conce/m Be it known that l., FRANK ll'amnn, a citizen ont' the United States, residing at Normal, in the county of McLean and State ci? illinois, have invented a new and useful Railroad Crossing, ot which the following is a specification.

lThis invention aims to provide novel means under the control ot' an operator whereby a continuous track may be formed, at the place where two tracks cross, thereby avoiding the pounding and consequent de terioration experienced at the intersection of two railway tracks.

lt is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention apertains. i

lVith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details ot construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing trom the spirit of the invention.

ln the accompanying drawings Figure 1 shows in top plan, a device constructed in accordance with the invention; Figure 2 is a section taken on the line 2-2 of Figure 1; Figure 3 is a fragmental plan showing one of the levers and attendant parts; Figure 4 is a bottom plan view of the rotatable actuating member.

The device formingv the subject matter oit this application contemplates the use of a foundation, denoted generally by the numeral 1, and, ordinarily, made up of ties and stringers. The foundation 1 need not be described in detail, because it will be changed to suit local conditions, and because the make-up ot the foundation is a matter of interest to a railroad carpenter, rather than to an inventor. Supporting plates 2, ordinarily made oit metal, are superposed on the foundation l. The plates 2 support the main rails 3 of a track 4, and support, also the main rails of a track 5, the track 5 intersecting the track 4. Angle rails 6 are common to the tracks 4 and 5 and are supported on the plates 2. The ends of the angle rails 6 are halved as shown at 7 into the ends of the main rail and are connected thereto by securing elements8, the construcvtracks 4 and 5.

tion being such that expansion and contraen` tion may be taken care of, a practically con` tinuous joint being afforded, nevertheless.

rllhe device includes auxiliary rails y9 disposed in pairs, the pairs of auxiliary rails 9 being alined with-the mainA rails of the f The auxiliary rails 9 are beveled and overlapped as shown at 10, each auxiliary rail having a base flange 11. llach auxiliary rail/9 carries connections 12 movable in slots 14 formed in the adj acentaui;` iliary rail, as shown in Figure 2.` Elongated slots 15 are fashioned in the danges 11 ot the auxiliary rails 9. Securing devices 16 pass through the slots 15 of the flanges 11 and connect the auxiliary rails 9 to the plates 2, as shown in Figure 2, for longitudinal move ment, as indicated in Figure 1. y

.as depicted in Figure 3,andas denoted by` the numeral 17, the plates 2 are'gcut away to receive levers 18, iulerumed intermediate theirends, as at 19 on the foundation 1. The levers 18 carry pivot elements 20, located on opposite sides of the ulcra 19 of the levers, the pivot elements being mounted in the flanges 11v of the auxiliary rails 9.

`The plates 2 are provided with openings 21,

receiving the pivot elements 2O and permit- Y i `a pedestal 26 a. spacer 27 being interposed.

between thepedestal 26 and the rotatable member 24, as depicted -in Figure. 2 of the 1 drawings. At i-ts lower surface'and adjacent i lto its periphery, the rotatable actuating member 24 is supplied with a gear ring 28 meshing into a pinion 29 mounted on a Shaft 30 journaled tor rotation in the foundation lor supported in any other suitable way.

In practical operation, whenrotation is imparted to the shaft 30, the pinion 2 1, co operating withthe gear ring 28, will rotate the member 24. When the member 24 is rotated, the levers 18 will be swung on their ulcra 19 in view of the fact that the projections 22 at the inner ends of the levers are received in the cam` slots 23( levers 18 are swung, motionl will be trans- When the-y ery mils and the angle mils. n this way.
