DAVID H. VALENTINE, OF BROOKLYN, NEV YORK.

RAILWAY-SWITCH.

SPECEFICATION orming part of Letters Patent No. 320,900, dated June 23, 1885.

Application filed February 25, 1885.

.T0 all whom it may concern:

Be it known that I, DAVID H. VALENTINE, of Brooklyn, in the countyol' Kings and Slate of New York, have invented a new and Improved Railway-Switch, of which the following is a full, clear, and exact description.

The object of this invention is to provide a practical railway-switch without a frog; and my invention consists of a triangular switchbeam having independent sides for a portion of its length and provided with a block secured between its sides at the larger end.

The invention also consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding` parts in all the figures.

Figure l is a plan view of a main track and siding` having myimproved switch, the switchbeam being shown closed in full lines and open in dotted lines. Fig. 2 is asectional elevation taken on the line x w of Fig. l. Fig. 3 shows my improved switch applied to two main tracks, the switch being shown open in full lines and closed in dotted lines. Fig. 4 is a plan view of a switch-beam to be used at curves.

Referring to Fig. l, A A A2 are the rails of the main track laid upon the sleepers B, and C C are the rails of the siding laid upon sleepers D in the ordinary way. E is the switch rail or beam. rlhis is by preference made of railway-iron and triangular in form, tapered at a, and enlarged or rounded at b, and it is pivoted to the sleeper F by the bolt c, that passes through the plate d, held at the larger end of the switch rail or beam, and into or through the said sleeper F. rIhe switch-beam is so pivoted to the sleeper F that the side fof the beam forms a continuation of the sidingrail C, and the side f a continuation of the rail A of the main track. The point a of the switch-beam reaches to the junction of the siding-rail C with the main-track rail A2, and the point is adapted to be swung from the rail A'Z (No model.)

to the main-track rail A, as shown in dotted lines in Fig. l, in which position it opens the switch. Y

Any suitable means may be employed for shifting the beam to open and close the switch.

Referring to Fig. 3, where two main tracks are shown, the rails AZ of each main track are bent at k to form the cross tracks or rails O O, and the two switch-beams E E are oppositely pivoted,with the points extending in opposite directions, so that these beams, with the bent portions of the rails A2, constitute the entire crossing or switch without the use of frogs, thus making the switch very cheap, and it is practical, reliable, not liable to get out of order, and very little labor is required to put it down and keep it in repair.

Referring to Fig. 4, the sides of the switch beam or rail E are drawntogether by a bolt, d', or otherwise, so that the sides form curves, so that when the switch is laid at curves in the railway the sides of the switch-beam will continue in the same curve of the main-track or siding rail.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The herein-described switch-beam, consisting of the triangular beam E, having inde pendent sides ff for a portion of its length, and provided with the block d, secured between the said sides at the larger end, as set forth.

2. The combination, with the rails A AA2 of a double track and the crossing-rails C C, of the triangular switch-beams E E, pivoted to form continuations of rails A G and A O', and of a length to swing across the main tracks, substantially as described.

3. rlhe switch-beam E, made triangular in form and having its sides curved, substantially as and for the purposes set forth.

DAVID H. VALENTINE.
