RAILROAD-SWITCH.

Specification of Letters Patent.

Application filed March 10, 1909. Serial No. 482,515.

- Patented June 15, 1908.

which the usual switch points are dispensed with and the switching from one track to another accomplished by means of blunt-end sections.

The invention consists in the general and specific arrangement of parts hereinafter dcscribed in which is comprised, in addition to the specific association of movable rail the exact alinexed rail sections and for looking as well as bracing the movsections means for insurin able rail sections in either of their operative positions.

In the drawings: Figure 1 is a plan view of the switch Fig. 2 is a sectionon the line 22 of Fig. 1; F i 3 is an enlarged section on the line 3-3 0 Fig. 1 showing the locking lever partly broken away; and Fig. 4 is a. plan View of same partly broken away; Fig. 5 is an enlarged section on the line 5-5 of Fig. 1; Fig. 6 1s a cross section on the line 6-6 of Fig. 5.

f, f are plates secured to the ties which, for urposes of clearness, are not shown in the rawings. To these plates the fixed rail sections are secured and the movable rail sections ivoted.

Referring first to the rail sections attached to the left-hand plate, a represents the end ofone rail of the through track and Z) the end of another alining rail of the same track.

a and b may, if desired, be fixed rail sections that abut against full length rails of the main track. These rails or rail-sections are fixedly secured to the plate f and are spaced apart'and adapted to be connected by a rail section 0 pivoted on the plate f, as hereinafter described, and so pivoted that the outer edge of its pivoted end adjoins the The rail section a is of such tion shown in dotted lines in Fig. 1,'it.just spans the space between a and 7).

(Z represents the end of one rail of the branch track, or a rail section adapted to abut against a rail of the branch track. It

is fixedly secured to the plate 7 and extends inside of the rail section a. and is spaced from the rail '2) a distance substantially greater than the distance separating rail seclions a and b. The rail section 6 is pivotally, secured to the plate f by means of a downward projection or pin it, on a thickened part of the rail, socketed in a lug g on the plate f (see Figs. 5 and 6). The rail section 6 is adapted, whenmoved into the position shown in full lines, to span the space between, and connect rail sections?) and (Z. The rail section 0 is pivoted on the plate f in the same manner that the rail section 6 is pivoted.

a The free or movable ends of rail sections-0 and e ar'e secured together by means of a link 2' connecting lugs j, j, secured respectively to the ends of c and e.

a, Z), 0, cl and 6 represent rail sections corresponding, respectively to rail sections a, b, 0, and 6 but secured to plate f in the same manner respectively that the last named rail sections are secured to plate f. In this group of rail sections, hcvever, the rail section a, which is adapted to connect the fixed rail a" and b, is substantially longer than the -rail section 6 which is adapted to connect the fixed rail a and branch rail 65; the arrangement in this respect being therefore the reverse of that of the group first described. 3

7c is a bar extending under the plates f and f and slidable in guides on the frame Z secured to the plates. Secured to the bar is is a block 722, which is connected by links a and a with blocks 0 and 0 secured rcspcctively to rail sections 0 and c. lVhen the bar is is moved to the right, rail sections a and c are moved into alinement with rails a and a respectively, and the main track is thus closed, as shown in dotted lines in Fig. 1. lVhen the bar 7; is moved to the left, as shown in full lines, in Fig. 1, rail sections 6 and c are moved into aline ment with rails a and a respectively, and the main track is open and the branch track closed, as shown in full lines in Fig. 1. To operate the bar is there is provided a hand lever 32 pivoted on the frame and connected by a link 9 with a lug r secured to the plate 7'.

s and s are blocks secured respectively to the outside, of the ends of rail sections 0 and 6. These blocks, and also blocks 0 and 0 (which may be, as shown integral respectivelywvith lugs j and j, y and project beyond the ends of the rails to which they are secured and serve to limit the movement of the switch in each direction. That is, when the switch is moved to the right, as shown in dotted lines in Fig. 1, block 8 engages rail 7), and block 0' engages rail 6', and when the switch is moved to the left, as shown in full lines in Fig. 1, block 3 engages rail 6 and block 0 engages rail To brace the switch from being moved by the impact of the'wl'ieel flanges striking the inside of the head of the movable ends of the pivoted rails links 6 and 6 connect respectively blocks a and s with levers a and u each pivoted at one end to a crosspiece Q) secured to plates f and f and at the otheend to thebar la.

The switch may be locked in either of the two positions to which'it is moved by means of a locking lever e0 (see Figs. 3 and This lever is pivoted to the lever u and has a forked arm 10 extending underneath bar I: and adapted when the arm w is depressed, to engage recesses formed in a block a: secured to the frame Z. Which of the several recesses will be in line with the arm on the locking lever w depends upon which of the two operative positions the switch has as sumed. hen the locking lever w is de pressed, a slotted portion thereof engages a lug y or secured to' the frame l. Each of these lugs is provided with a transverse orifice through which may be inserted a pin, padlock, or other device by means of which the locking lever in may be held in its locking position, thereby preventing the operation of the switch-bark.

a is a flanged guard plate attached at its opposite ends to the outer ends of links a and 92, thereby protecting the links from dirt or other damage.

e, z, z are .tie rods, similar to those employed on ordinary switches, connecting the movable rail sections.

- It will be understood that the terms main rails and branch rails are arbitrary terms employed for convenience of description and are without other significance, being in fact convertible terms. \Vlth this understanding it will be observed that in principle of construction the two sides of the switch are, in the embodiment of my invention illustrated, recise duplicates. That is, the short movab e rail sections 0 and 6' each connects a fixed rail common to both tracks with the outside rail of the two adjacent rails, whilehthe long movable rail section e and o'each connects a fixed rail common to both tracks with the inside rail of the two tracks. The duplicate movable rail sections are, however, alternately in operative position, as will be understood from the foregoing description.

Having now fully described my invention,

what I claim and desire to protect by Letters Patent is: y

1. In a switch, the combination with a pairof fixed rails forming one track section and four fixed rails, disconnected at their ends, forming two track sections, of a pair of movable switch rails pivoted respectively at the ends of the two fixed rails forming one of the last named two track sections, a pair of movable switch rails pivoted respectively at the ends of the two rails forming the other of the last named two track sections, and means to move said switch rail sections simultaneously on their pivots to connect the first named track section'with either'of the other two track sections.

2. In a switch, the combination with fixed. main rails a and b spaced apart, of a branch rail 65 alongside the rail a. and spaced from rail 6 a distance greater-than the space between the first named rails, main rails a and I). spaced apart adistance greater than the first named rails, a' branch rail d alongside rail a and spaced from rail 1) a distance less than thespace between rails a and b, a rail cpivoted at the end of rail a and adapted to be moved to connect rails a-and b, a rail e pivoted at the end of rail d and adapted to be moved to connect rails Z2 and d, a rail 0' pivoted at the end of rail a and adapted to he moved to connect rails a" and F), a rail e manually controlled means for moving said movable rails ontheir pivots.
