RAILROAD-SWITCH.

T 0 all whom it may concern:

Be it known that I, Gnonen D. iVoRLEY, a citizen of the United States, and a resident of Texarkana, in the county of Miller and State of Arkansas, have invented a new and Improved Railroad-Switch, of which the following is a full, clear, and eXact description.

My invention relates to switches for railroads of av character which control the traverse of rolling stock from a main track to an intersecting side track, and from the latter to a main track; and has for its object to provide novel details of construction for a railroad switch, which cooperate with a fixed frog point and pivoted wing rails therefor, so as to enable the eii ective control of the switch and dispense with guard rails usually employed in connection with a switch of the type indicated.

The invention consists in the novel construction and combination of parts, as is hereinafter described and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of a main track and a side track where connected, and of the improvement applied for controlling the connection therebetween; Fig. 2 is an enlarged plan view showing achanged adjustment of certain parts represented in Fig. 1; and Fig. 3 is a. transverse sectional view, substantially on the line 3-3 in Fig. 2.

In the drawings A represents cross ties spaced apart and disposed on a railroad bed, at a point where a switch is introduced between a main track and a converging side track. On the cross ties A, a main track rail 5 is seated and secured, and at aproper distance therefrom, as shown at the left in Fig. 1, a parallel track rail section ff is secured on said cross ties, the rails 5 and 5 constituting a main track. From the track rail 5 extends the outwardly-curved track rail 6, which is secured upon the cross ties A, and in service is an outer rail for a side track. Upon the cross ties A, at a suitable distance from the point where the track rails o and 6 are connected, a base plate 7 is seated and secured, said plate being 10- Specification of Letters Patent.

cated between the track rails 5 and 6, as shown at the right in Fig. 1. A transversely-disposed tie rod 7 may be provided as brace for the track rail 5, said rod being secured at its ends respectively upon the lower side of the base plate 7 and the track rail named, and it is to be understood that there may be any necessary number of transverse tie rods employed as usual, for tying the track rails together and holding them spaced apart a proper distance. Upon the base plate 7 a frog tongue 8 is secured, preferably midway between the rails 5 and 6. On the cross ties A, a suitable wear plate or plates 9 are secured, and on said plates 7, 9, which are on the same level, two wing rails 10, 10 are mounted. The wing rails 10, 10 that are coacting members for the frog of which the tongue 8 is a part, are each similarly bentlaterally at a, to give them obtuse angular form, and they are respectively disposed at opposite sides of the fixed frog tongue. The end portions of the wing rails 10, 10 which are seated upon the wear plate or plates 9 are spaced apart, and pivoted on said wear plate as shown at 6, b.

Two base plates 11 are preferably employed as supports for two track rail sections 12, 13, said plates seating upon the ties A at a suitable distance from the wear plate 9. The track rail section 12 is arranged parallel with the main track rail 5 and is alined with the main track rail section 5 one end of the rail section 12 being seated on the wear plate 9 and positioned opposite and near to the pivoted end of the wing rail 10, the other end of said rail section being seated upon one of the base plates 11. The rail section 13 is curved edgewise somewhat, to render it parallel with the side track rail 6, and is secured upon the wear plate 9 and the remaining base plate 11,'as shown in Fig. l, the end of said rail section, secured on the wear plate 9, being deposed near to and opposite the'pivoted end 7) of the wing rail 10:

Two switch points 14, 15, formed of T- rail sections are respectively pivoted at one end upon the base plates 11, opposite and near to the corresponding ends of the stationary rail sections 12, 13, as shown at c, c, in Fig. 1. The other ends of the switch points 14, 15 are cut away sidewise as shown in Fig. 1, so as to taper them to points that are adapted for lapped contact with the inner sides of the respective track rails 5 and (5. The pivoted switch points lat, 15, are at their pointed ends, secured upon a shifting rod 16 that extends between a cross tie A and an elongated timber or head block A, said head block projecting a suitable distance laterally from the main track rail 5.

The shifting rod 16, outside of and near to the main track rail 5, is connected to one end of a connecting bar 17, which extends outwardly, and at its outer end is pivoted upon the side of a rockable lever 18 that at an adjacent end thereof is pivoted in a box (Z that is secured upon the extension of the head block A. It will be seen that when the lever 18 is disposed horizontally, the shift ing rod 16 will be drawn outward and the sloped end of the switch point let be impinged upon the inner side of the main track rail 5, the point on the switch rail 15 being at the same time drawn away from the side track rail 6 at a point near its junction with the main track section 5*, as appears in Fig. 1.

The ends of the wing rails 10, 10, that are adjacent to the frog tongue 8, are spaced apart and connected together by a shifting bar 19, whereon said wing rails are secured, as shown at e in the drawings.

Upon or in suitable boxes or ring eyes 9 that project laterally from the other side of the main track rail 5, an elongated rock shaft 20 is loosely mounted, and thus disposed horizontally. A downwardlyproject ed crank arm 20 is formed or secured on the end of the rock shaft 20 that is opposite the shifting bar 19 and the crank arm and shifting bar are loosely connected by a link rod 21, said rod working below the rails. Upon the end of the rock shaft 20, that is adjacent to the shifting rod 16, a crank arm 20 is formed or secured, having a crank pin thereon that is rockably secured on the extended end portion of the shifting rod 16, as shown in Flg. 1 at i.

It will be noted that when the lever 18 is rocked outward and downward, as represented in Fig. 1, the laterally curved switch point 14 will be impinged at its tapered end upon the track rail 5, and a gap m is produced between the point on the straight switch point 15 and the rail 6. Simultaneously with the described adjustment of the switch points 14, 15, the shifting bar 19 will be moved endwise, so as to open a gap at between the switch tongue 8 and the wing rail 10, and force the wing rail 10 against the opposite side of the tongue 8, this relative adjustment of the parts appearing in Fig. 1, and it will be apparent that the switch is now adjusted for the free transfer of rolling stock from the side track to and upon the main track. In further explanation, it will be seen that the elevation of the lever 18 will rock the shaft 20, pull the shifting bar 21 toward the shaft, shift the wing rail 10 away from the tongue 8, aline the wing rail 10 with the fixed rail section 12 and close the free point of the switch bar 15 against the rail 6, thus closing the main track for traverse of rolling stock past the switch, this adjustment of the parts with relation to the wing rails 10, 10 and fixed rail sections 12, 18, being shown in Fig. 2.

It is apparent that as the wing rails 10 or 10 are pressed respectively against the side of the frog tongue 8 when the switch is open to the side track or main track, the usual guard rails may be dispensed with, and the switch be rendered strong, durable and perfectly reliable in operation.

As the shifting rod 16 and bar 19 are both located below the track rails, it is obvious they may be covered by boxing of any suitable kind, and thus be protected from obstruction to free action.

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