To all whom it may concern: i

Be itknown that we, HENRY E. BILLMAN and Lno R. MANN, citizens of the United States, residing at the city of St. Louis,

`State of Missouri, have invented certain new and useful Improvements in Switch- Stands, of which the following is a specilication. v

This invention relates to improvements in switch-stands and relates particularly to improvements in the switch-stand of our invention disclosed in our application for patu ent Iiled in the United States Patent Ollice if rangement of parts hereinafter more fully described and pointed out in the claims.

ln the accompanyingdrawings forming part of this specification, in whichlike numbers of reference denote like parts wherever they occur, Figure 1 is a perspective view, looking from the track, of the switch-stand embodying this invention; Fig. 2 is a plan u.

view looking down upon the switch-stand; Fig. 3 is a side elevation of Fig. 2 looking `from the track. z v A base 1 comprising in one piece the baseplate 2, apair of standards 3 (one standard preferably adjacent to each end of base 1 at the side thereof farthest from the track),

,a pillow-block intermediate said two standards (preferably on the `same side of base l @as standards 3), guides 5 intermediate the under-hung bearing 7 extending downwardly sides of base 1, bearing 6 preferably at the side adjacent to the track (notshown), and

i beneath base-plate 2 preferablyadjaeent to l bearing 6.

`Base-plate 2 is adapted to rest on ties 8 in the usual manner and is secured thereto by means of spikes or the like' (not shown) i through openings 9 in said base-plate and,

also, preferably at notches 10 in the outer edges of said base-plate, there being asmany such openings and notches `as maybe desired. Preferably one ormore openings 11 provided in base-plate 2 between ties Spermitwater to drain out of inclosures formed upon the said base-plate by the protruding edges l2of the web of the base l.`

A shaft 13 is supported in a bearing 141 in pillow-block 4, said shaft being retained in said bearing by cap 15,"\vhieh is fastened to said pillow-block by bolts 16 or other suitable means. One end of said shaft 13 has the throwing lever 17 secured thereto by any suitable means, the free end of said throwing lever preferably `bearing a weight 18 to facilitate the throwingof the switch-points (not shown). Thethrowing lever is arranged to move through substantially 180 degrees in a vertical plane and is positively limited in such movement by the pair of standards The standards 3 have their upper ends bifurcated so that, when the throwing lever 17 occupies substantially a horizontal position (best seen in Fig. l), said lever will rest upon a standard 3 and will extend between prongs 19 of the latter, one of said prongs being preferably longer than the other and having an opening 20 for the reception of a hasp or padlock Q1 or other suitable device for locking the throwing lever in its horizontal position. The other end of said shaft 13 bears one end of a crank 22, the other end of said crank bearing a crank-pin 23 with an anti-friction roller 2d revolubly mounted thereon, said antifriction roller being held on said pin by Cotterpin 25 or other suitable means. Crank 22 i preferably extends in the opposite direction from throwing lever 17 so that, when the latter `is moved through an arc of substantially 180 degrees above the horizontal plane through the axis of shaft 13, the former will be moved through an arc of substantially 180 degrees below said plane. Crank-pin 23 receives a member 26, said member having a vertical slot 27 through which crank-pin 23 extends.` The member 26 bears a pair of oppositely-extending arms 28 each of which is provided `with an elongated opening `29 running lengthwise the arm, each Opening having a pair of lugs 30 and 31, one,` 30, preferably located in the upper portion of said opening farthest from said member 26 and the other, 31, preferably located in the ylower portion nearest said member 26, each the drawings) said arms to operate a distant signal, crossover switch, derail, frog, etc. `(not shownin The arms 2S extend along base plate 2 and are slidably supported thereon by guides 5, which guides are preferably bifurcated for the purpose of receiving said arms as best shown in Fig. 1, and each bifurcated portion being preferably strengthened by buttress-like webs 33, and, moreover, each of said guides 5 being provided with openings 34 transverse the direction of said bifurcations and transverse the direction of the arms 28 in their extension along baseplate 1, which opening 34 is adapted to communicate with opening 29. A cotter-pin 35 or the like is preferably provided in an appropriate opening` 36 therefor in each guide 5 at or slightly above the level of the upper edge of arms 28, when said arms are slidably in place in said guides, to prevent said arms from lifting upwardly out of position in operation and to permit lugs 8O and 31 positively to perform' their functions hereinafter described. The lower portion of member 26 extends through an opening` (not shown) in the base-plate 2, said opening being provided to permit said member 26 with its lower portion extending through base-plate 2 to move forward and backward as arms 28 extending from said member 26 rslide forward and backward in guides along said base-plate, and a pin 37 borne by the lower portion of said member 26 Y (said pin having an anti-friction roller 38 revolubly mounted thereon and being provided with a cotter-pin 39 or the like for holding said anti-friction roller in place on said pin) extends through a cam slot 40 in the operating crank 41, which is rigidly mounted on vertical shaft 42 in underhung bearing 7 below base-plate 2, said crank being so mounted preferably between bosses 43provided as part of said bearing 7. Vertical shaft 42 is rotatably mounted inbearing 7 and extends upwardly therefrom through bearing 6, which is located immediately above bearing 7, and shaft- 42 vbears near its upper end the usual target vanes 44 and terminates with a lainp-plug45 `to allow a signal-lamp (not shown)v to be.

mountedv thereon in the usual manner.

The cam slot 40 is preferably vY-shaped, having two branches 46 disposed at substantially a right-angle to each other, and a third branch extending radially to the pin 37 and substantially bisecting the vertical angle of the branches 46, as shown in Fig. 2. Crank 41 is pivotally attached at 47 to one end of the connecting rod 48 by bolt 49 or other suitable means (Fig. l), the other end of said connecting rod 48 being connected to the switch-points (not shown) preferably to a tie-rod '(not shown) of said switchponit. f

Normally, the member 26 occupies a position with crank-pin 23 and anti-friction roller 24 inthe upper end of vertical slot 27 when pin 37 stands in the end of one of the branches 46 of cam slot 40 and thereby holds the operating crank 41 in such posi-v tion that said branch 46 coincides with the path of movement of pin 37, with the result ythat the switch-points (not shown) connect-V ed to rod 48 are held locked in their set position. When it is desired to throw the switch-points, the throwing lever 17 is` moved through an arc of substantially switch, and during the next V degrees of `the movement of the lever 17 the crank 22 moves the member farther in the same direction and thereby causes the pin 37 to enter the radial branch of cam slot 40 and to engage one side of same, whereby said pin rotates the operatingk crank 41 through substantially `.90 degrees, with the result that said operating crank effects the positive throwing of the switch-points (not shown) through the medium of the connecting rod 48. This rotary movement of the operating crank 41 causes the vertical shaft 42'to rotate through substantially 90 degrees and thereby effects the positive setting of the target vanes 44 and signal-lamp (not the lever 17, the crank 22 moves the member 26 farther and thereby causes the pin 37 to enter theother branch 46 of the cam slot 40 and to moveto the end of said branch, which branch will have been moved to a position in which it coincides with the path of movement of the pin 37. lThis movement of the lever 17 vcauses the pin 37 to lock the operating crank 41 in its new position and vthereby' prevents the switch-points (not shown), connected with operating crank 37 as hereinabove described, and the vertical shaft 42 `from being moved until the throw-f" ing lever 17 is' moved in the reverse direction through more than 45 degrees, as herey inabove described.

lt will be seen that, by reason of the connecting rod 48 being directly connected tothe operating crank 4l and said crank being rigidly mounted' on vertical shaft; 42, said vertical shaft 42, bearing target vanes 44 or signal-lamp (not shown) or both, moves synchronously with the switch-points (not i shown), borne by said vertical shaft. Durving the `last 45 degrees of the movement of lilo shown) and thereby causes the target vanes or signal lamp or both to indicate the exact position of said switch-points. It will be seen that this arrangement eliminates all lost motion and insures the positive throwing of the switch-points and the positive setting of i the signal.

As an auxiliary means for lockingthe `switch-points (not shown) in a set position, the' iollowing mechanism 1s provided. rflic lrod at an extension thereof to the track (not shown) "is connected preferably with the points ol the switch-tongue (not shown) in the paths of movement, respectively, o'll `corresponding lugs 30 and 31 of an `arm 2S as said arm moves orward and backward through guide as lever 17 is moved through an arc of 180 degrees 'trom the position shown in Fig. 1, to the position shown in Fig. or the reverse, and, wlienthe switchpoints are `in set position as hereinabove described, one of said notches 51,52 engages one of said lugs 30, 31 and through the extension of the rod 50 connected with the points of the switch-tongue (not shown) holds the point so set close up against the stop-rail (not shown) and locks same in that position thus providing a means `:tor lock`- ing the switch-points in a set position auxiliary to the means provided by the cope fr tion of a slot i6 withthe pin 37 andthe operating crank 4.1 throughthe connecting rod 118, as hereinabove described.

The present invention simplilies in many ways the construction ofthe switch-stand of our invention disclosed in our application, Serial No. 7 7 3,846, above-referred to, greatly reduces the number oit separate parts, provides various novel features, reduces the cost of construction by reducing the amount of machine work, lessons the labor and expense in assembling and erecting, eliminates a large number of bolts, nuts, and .fitting together ofparts, and provides adevice certain and positivein operation. For instance,

by forming the standards 3 integral `with base 1, not only are the number" ot' sepay rate parts reduced together `with their bolts and the like, but, also, the motion ot lever 17`may be positively limited to an arc of 180 degrees, because the base ot' said standards being` integral with the base ot' the switch-stand, the varying of the level ot' the ties to which said baseis secured will not` affect the standards to alter their adjustnient relativeto the limited motion ot' said that operating crank mounted thereon below the base-plate 2 oi lever, as may be the case when each standard is a separate part and is separately spiked or bolted to separate ties, and, also, a number otbolts and the like are eliminated and the labor and expense et assembling and litting together oi parts is eliminated. by coi'istructingthe iillow-block 4; integral with the base, not only is the construction siniplilied, the nuniberof separate `parts reduced, `and the expense of assembling those parts avoided, and the like, but, also, a substantial pillow-block with a single bearing` t'or shalt 13 is provided instead oil the two bearings provided in our invention disclosed in our application, Serial No. 773,816 abovementioned. i

The base-plate 2 of the switch-stand of the present invention is substantially a tlatsurface having air opening in its floor thus permitting the lower portion o'l member 2G to extend below said base-plate so that associated parts are located, connected, and operate below said base-plate, thus avoiding the more expensive U-shaped base disclosed `in our prior application, Serial No. "773,8et6.

The underliung bearing 7 is a novel feature not provided lor in the invention disclosed in our said prior application tor i patent and provides a simple and cheap means lor rcvolubly mounting shaft Ll2 so il may be rigidly base 1. Further, the novel features of construction and operation of an auxiliary locking device of the present invention operativethrough anopening in guide 5 (guides being integral with the base in the present invention) by nieans oi notches 51 and 52 on rod 50 cooperative in an opening .29 communicating with said openingl in guide 5, are not shown in our invention disclosed in our said prior application. These and other novel features o'l construction, arrangement ot parts, and o'l" operation described in this specification are substantial ad "antages provided by the present invention that switchstands ot other inventions `do not disclose.

Various changes in the details of construction and arrangement o'l parts may be made `without departing 'from the nature and spirit of this invention,
