v -under;side of the: portion 5%, of thebase -.plate 5 is a bell-crank' lever; -pivoted" as .withvthe connectingmod. The bell-crank ile-yer 6 is o-fi laminatedconstruction, being vzfonnedfottwof sections. 11', (as sheet metal stampings) connected together: and spaced apart by a spacing plateiorv disk 12, the arms 13. of thegsectionsllqhaving ioppos ed ofisetoportions v14,. between which a I pivotapivot OIPQSCIQW bolt 16. Ahpair of com- Lpanionlinks 17 are attached at one endto the'pivot-block:15, by a' pivotf l8, the said .pivot 18 being at right: angleshto thepivot 16,, Theopposite endsof the links 17' are pivotally-aattached,a as" at- 20, to a pivot block 1 21, similar:- in construction: to the block, 15, and the said block 21-is pivoted as .at 22-,betweenathe right angle 1 extensions 23 and 24: J' of I a. throw-regulating lever 30. This lever 30 isof stamped construction and is formednwith abase 31,..havingnpturned edge flanges 32, the: said flanges 32 being parallel atytheir lower ,portions '33 wand symmetrically flared at their upper p0r-- tions'34; at-an angle.ot'30,ffor a purpose hereinafterdescribed, a

block- 15, of a toggle means, is connected-by lvertical portion: 38, provided with'an open-1 ties 4 are extended to provide-a seat for the the offset portion 38 and the base 31. The bolt41 extends through .the base 31 and.

through a' pressed-out b,oss.,45, of the vertical. portion of the base plate 5,-to pivotally connect throw-regulating lever and its switch lever 42 thereto. .7

The automatic operation of the switch is as follows: I I

When the switch points or rails .2, 2,:are

set as shown in Fig. 1, and a train approaches slowly-from the direction indicated byflthe arrow along the portion of the track 50, the wheel flanges will engage at the' point 51 between the switch-point2 and the fixed rail 1, to throwthe points 2 in the direction of the arrow. The connecting rod 3, attached to Y and spacing the said points 2, "2, 'will be -moved to turn the bell crank, lever 6. Through the toggle means, connecting the bell crank lever with-' the switch-throwing lever, the said switch-throwing orhand lever will be: brought'to a position in which the inside surface (SO-of one of the flared flanges 34, (see Figs 3 and 4),- will'act to bring theilever 42*and 'itsweight 43 to a position in whichthe .center of gravity of h the said'lever and weight will be arrested at 1 a point, to the right. or. short of the "center line indicatedat 61 butnear tov it, at which time the switch points-will becompletely thrown, the flange of each oncoming wheel acting successively to maintain the switch points in their open lposition until the-car or train has passed the'same, after' wh'ich the weight will a'ctto brin the said'points to their initial position. i the train or car moves at a greater'rate'of speed, the switch lever is given "sufiicient' en, however,

' momentum to carry its center of gravity beyond the vertical line 61, swinging, theleverto an opposite side to positively lock the switcnpoints 2 against the 'rail"f50 of the main line.

The switch rails therefore can be moved from one position to a second by the wheels of the moving cars and automatically ie turned as a spring switch after the cars have passed the switch or are maintained in their throw-over position dependingupon the rate ofspeed atwhich' the cars passthe switch. The switch rails may then bej'set,

say closing the mainline rails to thesiding and by passing the switch rails at a low rate of speed from thesiding rails onto the main .line rails, the switch: rails are moved by the wheels to "properlyposition them for the 5 main line entrance, returning automatically j after the cars of'the train have 'p'assed'onto the main line rails to'a gain close the switch rails tov the siding against any cars moving in-an opposite direction. Moving'thecars "at a secondor higher rate of speed over the "switch rails, results in the wheels of the V r gags, strpihihg the right 'switc'h ra Wide! and impact, which will forcibly move theswitch. ,rails to the left and thereby transmit or impart an accelerated motion to'the switch- 1 throwingparts,moving the switch lever 30 tinguished from any lost motion or loose connection, which would bereadily injured by heavy or repeated shocks or jars, and interfere with 'afree and and switch rail connecting or actuating rod provides a flexible coupling 1 for a switch lever throwing inalineparallel to the rails of a simple, compact and durable construction.

Aideviceof the class described, an angle base plate, -a.- lever pivoted tofthe; under horizontal side of said plate 'on a vertical axis, a lever pivoted on the vertical side of'said plate on a horizontal axis, and a connecting link between said levers, its op positeends having a universalcoupling'con- .nection with the'lever to-which'it connects. j

2. 'A device'of the class described, a base easy manual throwing I of theswitch. I l The method of connecting the switch lever member, a pair of levers pivoted upon said 7 base member with their axes at right angles to each other, and'a connecting linkbetween said levers, its opposite ends each having a universal coupling connection with the lever to which it connects. Y

3. 'A device ofthe classdes'cribedsa base 5 member for supporting the switch throwing members; a'bell crank lever pivotallysup" ported upon the basememben'adapted to be connected- ,to the sw'itch"rails," a two-part switch-throwing lever, j one part pivotally 'supported 'upon said b'asemember and'the Y second'part pivotally mountedjuponthe said first part, and a connecting link between said bell crank .lever and two-part switch throw ing lever, its opposite ends'each having a universal coupling connection with the lever with whichjit joinsjf f 4.'In a switch-stand, an angle platebase member adapted to 'be "m0unted' "longitudinally parallel with the rail to beoper'ated,

5. Ina switch-Stand, a base member, a pair of levers pivoted upon said-base member, each upon an axis relatively at right angles to the other, coupling means for connecting said levers, one of said levers connecting with the switch. rails and the second formed of two parts, one part joined to said coupling means and the second part pivotally connected upon the first part and adapted to swing thereon within a the confined limits upon opposite sides of a central radial line of said parts. I

V 6. In a switch-stand, a base, a lever pivoted on saidbase for connection with the switchrails, a switch-throwing lever pivoted on said base to swing on an axis at right link coupling means connectingsaid lever and having a universal connection with each lever, and an end weighted extension pivotally mounted upon said switch-throwing lever, having a limited independent arc of movement thereon at opposite sides of a central line through said switch-throwing lever.
