RAILWAY-SWITCH STAND.

Specification of Letters Patent. Patent d J l 11 1922 Application filed April 4, 1922 Serial No. 549,490.-

To all whom it may concern:

Be it known that I, Lmcr FAOGIUTO, Sr., av citizen of the United States of America, and resident of Flushing, county of Bel mont, and State of Ohio, have invented cer tain new and useful Improvements in Rail mum of effort and without bending over it,

the operator may conveniently grasp or otherwise engage it for effecting shifting thereof from one operative position to the other to throw the switch.

A further object is to provide a simple construction of switch stand for mine tracks which may be operated for throwing a switch by the foot of the operator as a moving car upon which he rides approaches the switch.

With these and other objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafterbe fully described, reference being had to the accompanying drawings, in which Figure 1 is a top plan View of the invention with portions of the curved frame members broken away;

Figure 2 is a side elevation; and

Figure 3 is a section on line 3-3, Fig. 2.

Referring to said drawings, 1 indicates each of two similar upright metal arches constituting members of a frame, each having feet 2 formed upon its opposite ends for mounting in firmly seated position upon a suitable support or foundation adjacent to I the traclrway. Said arches are disposed in parallel relation at a spaced distance apart to afford therebetween a passageway for the travel of an operating lever 3, as will hereinafter be explained.

The lever 3 has its lower end pivotally mounted upon a centrally located pin 4: carried by a pair of horizontal bars 5 which have their opposite ends received between and rigidly mounted upon the upright side portions of said arches 1. Said lever projects upwardly between the curved portions of said arches and preferably has a handle portion 3 formed upon its upper end, whereby 1t may be grasped by hand for shifting purposes.

Carried on each of the opposite sides of the lever is a stationary arm .6 to which is attached, as through the intermediacy of an adjustable eye-bolt 7, the upper end of a re tractile coil spring 8, said spring being engaged with the eye of said bolt. The lower end of said spring is attached to an eyepiece 9*- formed on a pulley block 9, and the latter carries a pulley wheel 10 in underlying engaged relation to a horizontal rod 11 which constitutes a trackway for said pulley wheel, and which has its opposite ends mounted in laterally extending arms or lugs 12 carried in suitable positions, as by the adjacent bar'5 at points adjacent to the upri ht portions of said arches.

Tivotally mounted upon the pivot-pin 4: at one side of the lever 3 is an intermediate portion of a supplemental lever 13 which has one end portion thereof extending clownwardly in approximate alinement with said lever 3 and is pivotally attached to an end of the bridle 14 which connectsto the switch pointor other shiftable member of the switch (not shown) and through which shifting movement is imparted to such member. The opposite end portion of the supplemental lever 13 is bent or doubled back upon itself, forming an intermediate upwardly extending bow, and has its end mounted upon the pivot-pin at at the opposite side of the lever 3. The bowed portion of said supplemental lever is divided longitudinally by centrally slitting the same and then spreading the thereby-formed bow members 15 apart in opposite directions a distance somewhat exceeding the width of the lever 3, which latter occupies a position between said bow members, as shown.

It will be noted that the levers 3 and 13 are mounted upon the pivot-pin 4 in a slotlike recess 16 provided between the middle portions of the bars 5 and formed by bowextent of the throw of the operating lever 3, the latter seating against one or the other of the bow members of said supplemental lever, according to the direction in which it has been shifted, as is clearly indicated in Fig. 2. p I

In practice, when the operating lever 3 is shifted from one limit of its movement to the other, it carries therewith the supplemental lever 13, effecting reversal, through thebridle 14L, ofthe position of the movable member of the switch. Due to the fact that thesprings 8 are at all times under strong tension, the lever 3 is manifestly held firmly against chance displacement from either of its opposite limits of movement. During thefirst half of the shifting movement, the tension of said springs gradually increases, requiring the application of considerable actuating force, due to the increasing vertical distance of the eye-bolts 7 from the pulley-trackways 11; and when the center of such'movement, at which said springs occupy positions parallel to said lever, has been passed, saidsprings actuate said lever to instantly move to the opposite limit of its movement. in such movement, the pulleys 10 travel along said trackways 11. i

The throw of the lower end of the supplemental lever 13 is obviously less than would be that of a lower end portion of equal length provided by extending the lever 3 downwardly; consequently, said supplemental lever permits the lever 3 to have a greater swing in effecting the requisite shifting of the switch and, therefore, provides for the switch being more effectually retained in its adjusted position. I

lVhat is claimed is 1. A switch stand comprising a pair of parallel frame members of arch form relatively positioned to form an intermediate passageway, bars disposed horizontally between the upright portions of said members,

an operating lever pivotally mounted on said bars and having connection with the switch shifting bridle, said lever being movable along said passageway, retractile coil springs attached to and depending from said lever, pulleys suspended by said springs, and horizontal trackways beneath which said pulleys travel in shifting movement of said lever.

2. A switch stand comprising, in association with the shiftable bridle of a switch, a pair of parallel frame members positioned relatively to provide an intermediate passageway, a pivoted lever movable in said passageway and having connection with said bridle, a pair of horizontally disposed rods, pulleys arranged for travel along the under sides of said rods, and verticallydisposed coil springs interposed between said pulleys and said lever and shiftable with the latter, said springs tending to maintain said lever at either of the limits of movement ofithe latter.

'3. A switch stand comprising, in association with the shiftable bridle of ,a switch. a pair of parallel frame members positioned i relatively to provide an intermediate passageway, said members being of arch form, a lever extending upward through and movable along said passageway, a stationary member having said lever pivotally mounted thereon, a supplementary lever intermediate the first mentioned lever and said bridle, a pair of horizontally disposed rods,

pulleys arranged for travel along the under sides of said rods, and upright coil springs interposed between said pulleys and the-first mentioned lever and shiftable with the latter. Q

4. A switch standcomprising, in association with the shiftable bridle of a switch, a pair of parallel frame members positioned relatively to provide an intermediatepassageway, said members being of arch form, a lever extending upward through and'movable along said passageway, horizontal members having their opposite ends carried by the upright portions of said frame members, and lever having its lower end pivotally mounted between said horizontal members, a supplementary lever pivotally mounted upon said horizontal members atone side of the first mentioned lever and having 2 depending end pivoted to said bridle, said supplementary lever having relatively inclined upwardly extending portions located forward and rearward of said first mentioned lever and adapted to be engaged by the latter in its shifting movement whereby said supplementary lever is shifted said pulley and said lever, said spring being shiftable with said lever and adapted to draw said pulley therewith along said trackway,

the relative arrangement of said lever, spring and trackway beindg such that the spring is subjected to gra ually increasing tension during the first part of the shifting movement in either direction and t0 gradually decreasing tension during the final part of such movement.

In testimony whereof, I afiix my signature in presence of two subscribing witnesses.
