SWITCH FOR ELEVATED CARRIERS.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed April 6, 1918. Serial No. 227,147.

, citizen of the United States of America, and

a resident of Monticello, Jones .county,1owa, have invented certainnew and useful Improvements in Switches for Elevated Carriers, of which the following is a specification.

My invention relates to improvements in switches for elevated carriers, and the object of my improvement is to ,supply'for use in connection with an elevated main trackrail, a switch-rail movably connected thereto and a plurality of siding rails adapted to be associated in turn by means of said switchrail with said main-track rail, means for shifting said switch-rail into alinement with either iding-raihsaidmeans being equipped with astop or stops for closing communication from the other siding-rail or rails to said main track-rail, and said means including resiliently controlled securing means for holding said switch-railin an adjusted position and adapted to become disassociated before shifting the switch-rail.

This objectI have accomplished by the means which are hereinafter described and claimed, and which are illustrated in .the accompanying drawings, in which Figure 1 is a topplan view of my improved switch; Fig. 2 is a front elevation thereof, with parts broken away; Fig. 3 isarear elevation thereof with parts in cross-section or broken away; Fig. 4; is a central.longitudinalsection thereof, and Fig. 5 is a diagram of a track installation within a building, including my switching device.

Similar numerals of reference denote corresponding parts throughout the several views.

Referring first to Fig. 5, which is a diagram of a=building 35, such as a stable, said building having a doorway 36, the numeral 32 denotes a main elevated track-rail conducted from without intosaid building, to-

-deliver to-za .pluralitypf siding- rails 26, 29 and, 30, also elevated, ,andu-pon either of which .may rollthewheeled carriage 34 of epen g tt 'r r e ,0 th Jik These siding rails are made to approach each other near the front ofthebuilding, their extremities converging adjacent to the front-of the switch 17, the latter supporting a short switch-rail 23 pivotally at 22 on a hanger 21 depending from a rear cross-bar 20, and said pivotal connection leads .into' the abutting end of the main track-rail 32.

The frame of the switch mechanism comprises bent diverging side channel-bars 18 secured at their rear ends to said cross-bar 20, and at their forward ends to the ends of an arc-shaped casting 17. Said casting 17 is fixedly supported by hangers 19 from the floor timbers overhead. The hangers 2 5, 37 and 28 support theends of the siding- rails 26, 30 and29 respectively, and are fixedon the casting 17 to dependtherefrom.

The numerals 2 and 4 denote slides which are mounted to slide upon an arc-shaped cross-bar 1 whose ends are secured to depending lugs on the ends of said castings 17. The metal slide 2 is longer than the other slides 4. at its opposite ends, the slides 1 having integral arms extending underjthe' opposite ends of the slide 2, andpivotally connected to lug thereon by means of pintles 31. One of the lugs on said slide 2 is extended downwardly to provide a hanger 1 supporting the switch-rail 23. The laterally arranged slides 4 have integral outwardly extending offset parts 3 which provide bracketed stops for a purpose to behereinafter described.

Referring nowto Figs. 3 and 4c, themiddle slide 2 has rearwardly extended spaced lugs 5 connected by'means of a pintle 8 upon which is pivotally mounted between said lugs, a lever 10 having lateral ears orificed to receive a cable 12 whose middle portion is knotted at 11 to prevent its slipping through said orifices.

ing forwardly from said pivotal connection, the lever 10 has an arm 7 which is seated in a notch in the slide 2, being caused. to

This lever extends upwardly from said pintle, and a relatively strongenter the cross-groove 15 in the lower edge of said cross-bar 1 by means of the yielding resilient traction exercised by said spring. This looks the slide 2 to said cross-bar 1 with the switch-rail 23 in line with one of the siding-rails. Other notches 15 are provided in the cross-bar 1 at proper intervals to provide engaging means thereon for the arm 7 in adjusted positions of the slide 2, to permit of the witch-rail being adjustingly shifted into line with either of the other rails and secured in the adjusted position.

The slide 2 has on its top a spaced plate 14, and rollers 13 are mounted in the interspace, the cable 12 being carried about the rollers oppositely and laterally to pass over rollers 38 mounted between pairs of lugs 27 depending from the ends of said casting 17.

Referring now to Fig. 1, it will be seen that when the slide 2 is secured by above described means adjustably upon the cross-bar 1 so as to aline the switch-rail 23 with one of said siding rails, the bracketed stops 3 of the other slide 4: are positioned across the abutting ends of the other siding-rails, so as to effectually bar communication, and thus prevents an open switch in those locations, so that a carriage cannot run ofi? these rails while another is in use.

To shift the connected slides, in either direction, either depending cable-end may be pulled downward with some force, the lever 10 thus first being rocked to compress the spring 9 while disengaging the arm 7 from the notch 15 on said bar 1. A continued pull on the cable shifts the connected slides along the bar 1 until the slide 2 is medially positioned over another notch 15, when the spring causes said arm to engage with the notch, thus locking the switch-rail in alinement with another siding-rail.

I have provided means for vertically adjusting the level of the cross-bar l to thereby allow the switch-rail 28 to be maintained with its upper surface in the same plane as the fixed rails 26, 30 and 29. Referring to Fig. 3, this means comprises set-screws 42 mounted in the lower part of each end of the casting 17 and bearing against the lower edge of the cross-bar 1. To hold the crossbar in a vertical adjustment, the casting is slotted at 89, and a bolt 4:0 passed through the slot and secured by a nut 4C1. Either end of the cross-bar may be raised or lowered by said means to keep the switch-rail in operative relation to the other rails.

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

1. In combination, a plurality of fixedly supported siding track-rails, a main trackrail, a switch-rail movably connected to said main track-rail to have its free end moved into line with either of said siding trackrails, supporting-means, a transverse bar supported thereon, a slide mounted on and movable along said transverse bar, a stop connected to said slide, said switch-rail being connected to said slide, and said stop being positioned across one of said siding traclorails when the switch-rail is alined with another siding track-rail.

2. In combination, a plurality of fixedly supported siding track-rails, a main track rail, a switch-rail movably connected to said main track-rail to have its free end moved into line with either of said siding trackrails, supporting-means, a transverse bar supported thereon, a slide mounted on and movable along said transverse bar. said switch rail being connected to said slide, a stOp connected to said slide to project across and bar one of said siding-rails, when the switch-rail is moved into line with another siding-rail, and means for detachably securing said slide to said transverse bar with said switch-rail in alinement With either of said siding-rails.
