UNITED STATES HARRY LUTHER YOUNG, OF PUEBLO, COLORADO.

RAILWAY-SWITCH CONSTRUCTION.

Specification of Letters Patent.

l atented July 17, 1906.

Application filed March 21,1906. Serial No. 307,16 7.

To all whom it may concern.-

Be it known that I, HARRY LUTHER YOUNG, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented new and useful Improvements in Railway-Switch Construction, of which the following is a specification.

My invention relates to railway-switches, and particularly to those of city or suburban roads, the movable element or switch-point of which is apt to become clogged or impeded by the accumulation of dirt and other debris.

The principal object of my invention is to provide a rigid, durable, and efficient sup port for the movable switch-point and one which will be self-cleaningthat is, will be automatically cleaned by the movement of the switch-point in its normal operation. My construction prevents the accumulation of dirt, 620., both beneath the movable switch-point and also at its sides.

An embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the railway-switch. Fig. 2 is a detail showing the attachment of the operating-rod to the switch-points. Fig. 3 is an enlarged detached view in perspective of the point-support and rail. Fig. 4 is a similar view of the supporting-chair,- and Fig. 5 is a transverse section through the complete structure,

showing also a pit for the reception of the dirt or debris.

Referring to the drawings, A is a switchrail having an upright tread portion a, arranged in alinement with and adapted to form a continuation of the track-rail B. Switch rail Ahas also abase portion a, adapted to support the movable switch-point C, pivoted at c, and is provided with bolt-holes a or other suitable means for attachment to its supporting guard or chair D. This guard or chair D is spiked to the cross-ties E and forms massive and rigid support for the switch.

Base portion a of switch-rail A is slotted, as at a to receive the operating-rod c, which is pivotally connected to the switch point or points 0 by pin a and provided at one end with any suitable means 0 for attachment to the switch-actuating devices. (Not shown.)

"In Figs. 1 and 2 I have shown two movable switch-points for a single switch; but it will be understood that this is not essential, as only one may be employed, if preferred.

In order to prevent accumulation of dirt about the switch-points, I provide the base portion a of switch-rail A with a set of slots or openings a, preferably arranged transversely and having a flat substantial strip a between them for the efficient support of switch-point C. These strips a being flat will wear for a long time. In order to prevent clogging at the sides of the switch-point by dirt which fails to drop through the base slots or openings w, I provide the upright tread portion a also with a set of openings a, which are staggered with relation to openings a and each one is opposite one of the flat strips a so that dirt which is pushed laterally along the flat strips a will pass out of openings a and will not impede the movement of the switch-point. Openings a may be archshaped, as shown, or they mav have any desired shape.

The guard or chair D is provided with base-openings d, which register with openings a of switch-rail A and has guard-flanges (1 d Between these flanges and switch-rail A a space d isallowed through which dirt may pass from said switch-rail A. The up per edge of flange d projects toward and engages the side of tread portion a of the switchrail to form a brace or support therefor. .AIl." jacent flange 0Z I provide a series of openings (Z in the base of guard or chair D, which openings are staggered with respect to openings d, so as to come opposite openings (1 of the switch-rail A. Beneath the whole structure is provided a suitable pit (1 from which discharged dirt may be removed.

Having described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a railway-switch structure, the combination with a movable switch-point, of a supporting-base therefor provided with discharge-openings and having a lateral flange, said lateral flange being provided with. discharge-openings staggered with relation to said supporting-base openings, substantially as described.

2. In a railway-switch structure, the coinbination with a movable switch-point, of a supporting-base therefor provided with dis charge-openings with substantially flat supporting portions therebetween, a lateral flange for said base provided with dischargeopenings staggered with relation to said base openings and op osite said supporting portions, substantia ly as described.

3. In a railway-switch structure, the combination with a movable switch-point, of a supporting-base therefor provided with discharge-openings and having an upright raildescribed. I

5. Ina railway-switch structure,- the combination with a switch-point-supporting base provided with discharge-openings and having a lateral flange also provided with dischargeopenings, a switch-point pivoted for move ment upon said supporting-base and an operating-rod pivotally connected to said switchpoint, said supporting-base being provided with a channel to receive said rod, substantially as described.

6. In a railway-switch structure, the combination with a movable switch-point, of a supporting-base therefor provided with dischargeopenings and having an upright tread-flange also provided with dischargeopenings, and a chair for said supportingbase provided with discharge-openings to cooperate With said supporting-base and tread.- flange openings, substantially as described.

7. In a railway-switch structure, the com bination with a movable switch-point, of a supporting-base therefor provided with discharge-openings and having an upright railtread portion also provided with dischargeopenings, and a chair having a flange formed to engage and brace said upright rail-tread portion, said chair being formed with openings to cooperate with said discharge-openings, substantially as described.

8. In a railway-switch structure, the combination with a movable switch-point, of a supporting-base therefor provided with discharge-openings and having an upright railtread portion also provided with dischargeopenings, and a chair having a flange formed at one side to engage and brace said upright rail-tread portion and a second flange at the other side to constitute a guard-rail, said chair being formed with openings to cooperate with said discharge-openings, substan tially as described.

9. In a railway-switch structure, the combination with a movable switch-point, of a supporting-base therefor provided with discharge-openings and having a lateral treadflange also provided with discharge-openings, and a chair formed with a set of openings registering with said base-openings and another set registering with said tread-flange openings, substantially as described.

10. In a railway-switch structure, the combination with a movable switch-point, of a supporting-base therefor provided with dischargeopenings and having a tread-flange, said tread-flange being provided with dis charge-openings staggered with relation to said. supporting-base openings, and a chair formed with one or more upright flanges and with discharge-openings registering with said base and tread-flange openings, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HARRY LUTHER YOUNG.
