Application filed August 3.1906. Serial No. 329,053.

To (ti/Z whom it may cancer/t.-

ROWSKI, a citizen of the United States, and a resident of Monclova, in the county of Lucas and State of Ohio, have invented a certain new and useful Mechanical Movement; and I do her by declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to an improved mechanical movement particularly designed for use in connection with single or double railwayswitches for throwing the frog or switchpoints thereon, but may be used in any situation where it would perform its function in a proper manner.

l'he primary object of my invention is the provision of simple and efficient means which is operated from a moving car to effect a positive opening or closing of a switch which the car is approaching.

The operation, arrangement, and construction of the parts of a preferred embodiment of my invention is fully described in the following specification and illustrated in the accompanying drawings, in which Figures 1 and 1 illustrate a plan view of a track, the latter figure being a continuation of the former, and the associated n echanisin comprising the features of my invention for operating the frogs or switch-points of right and left switches, the incasing boxes of the operating parts being shown as wholly or partially removed fro .n the associated parts. Fig. 2 is a transverse section taken on the line y y in Fig. 1. Fig. 3 is a longitudinal section on the line 2 ,2 in Fig. 1. Fig. 4 is a front elevation of the transverse switch-rod and its associated carrying parts shown in Fig. 1, with the latter parts partially in section, and the rod fixed to its sliding block by a pin. Fig. 5 is a perspective view of the trip-lever and portions of its attached rods. Figs. 6 and 7 are longitudinal sections taken on the lines m a: and cc 113, respectively, in Fig. 1, with the cooperating draw-bars in the latter figure shown as moved to a position in which they just escape contact with each other, and Fig. 8 is a front elevation of the oscillating wedge block carrying member with its wedges and operating-bars.-

1 Referring to the drawings, 1 1 designate Be 1t known that I, VALENTINE SMO-' the rails of a main track having the right and left hand switches or sidings 2 and 3 leading therefrom, and provided with the frogs or switch-points 4 and 5, respectively.

It will be noted in the drawings, due to the proximity of the two switches, that I have positioned the mechanism for operating the first or right-hand switch 2 intermediate the operating mechanism and frog of the second switch 3 but I wish it understood that I do not desire to restrict myself to this disposition of the parts or to the use of the two operating mechanisms in conjunction with the same track, as each is entirely independent in its action from the other.

As each switch-operating mechanism is substantially the same, except as hereinafter noted, I will confine my detailed description to the mechanism operating the first frog or switch-point 4:, which mechanism is shown in Fig. 1. The frog is primarily controlled from an approaching car by the lowering of a contact-piece 6 therefrom, which is glided into an alining trorzgh or grooved way 7 in the bed of the track and therein has sliding contact with the trip-arm 8" of the main operating-lever 8, which arm normally lies transversely of the path of movement of the contact-piece. This arm operates within slots 9 in the walls of the troigh 7 and is moved from the position shown in Fig. 1 to that shown in Fig. 1 by the contact-piece 6, passing thereby. The trot gh 7 is shown as provided 1th a flared moi th 7 and inclined I way 7 b to facilitate the finding of the troi gh by the contact-piece. The lever 8 is carried by a bracket 10, which projects ithin an opening S therein, and is formed ith the angled weight-arms 8 and S. Carried by a bracket 11 at one side of the lever 8 is a bellcrank lever 12, having the arms 12 and 12 which are substantially eqial in length to the arms 8 and 8 of the lever S. The lever 12 is caused to move in r nison ith the lever 8, ch e to a rod 18 connecting the inner arm 8 of the latter with the outer arm 12 of the former, and these levers are normally retained in the position shown in Fig. 1" by the tension member 14, which connects the arm 12 of the lever 12 with the incasingboX 15, as shown. Connected at their rear ends to the arms 8 and 12 of said levers are the draft- rods 16 and 17, respectively, which i have their forward ends formed with cross heads 16 and 17 a for operating, as hereinward ends connected to opposite ends ofthe i centrally-pivoted horizontal oscillatory member 24, which is carried by the bracket 25 in advance of the glide- blocks 18 and 19. The

contiguous ends of the draft-rods 16 22 and 17 23 are formed withcooperating hcoksl6 for the purpose hereinafter described. At the ends of the member 24 are also pivotally carried the two forwardly-projecting oppositely-beveled wedge- blocks 26 and 26 which are adapted, when the member 24 is oscillated, to have their wedge surfaces alternately coact with the opposite ends of the slide-block 27, whereby to drive it first in one direction and then the other. This slideblock is carried by a transversely-disposed trough member 28, which is provided adjacent its ends with transverse openings 29,

through which the wedges 26 26 operate.

Formedcentrally on the Lpper surface of the slide 27 is'a boss 27 which projects through a suitable opening in the top of the trough member and has an opening extending lon- .gitudinally of the slide through which the switch-rod 30 extends.

This rodhas its ends reciprocally srpported by the apertured cars 27 rising from the ends of the 1L101Tgh,'OT in any other'stitable manner, and has one end connected to the associated frog or'switchpoint 4 by a link or connecting-rod 31.

.Either a positive or yielding reciprocatory movement may be communicated to therod 30 from the slide 27 for the piirpose'of throwing the connected frog, dte to the inserting of a pin 32 in alining apertures in the boss 27 and rod 30, as shown in Figs. 1 and 4, or the positioning of coiled compression-springs 33 33 between the boss 27 and fixed pins 33 on the rod 30, as shown in Figs. 1 and 4, thus effecting in the latter case a yielding resistance between the slide and rod. To accomplish a positive reversing movement of the member '24 each time the lever 8 is tripped, for the pi r- 1 ose of throwin a connected switch-fro I provide each gt ide-block 18 19 with the dot ble stiperimposed grooved ways 20 and 21 and form the forward portion of each dividing rib 34 thereof with an oscillatory tongr e 35, which is pivoted to the end of the fixed portion of the rib, as at 35, and forms a continuation thereof. These tongr es each have their lower forward edges beveled and term inating in a point which when lowered rests upon the base of the lower way 20, this forming inclined ribs for connecting the bases of the lower ways with those of the 1 p- A fiat spring 1 cooperating hook of its associated rod 22 23,

per ways, as shown in Fig. 7.

36 is secured to the base of each block 18 19 and has its free end coacting with a pin 37, which projects from the contiguous tongue throi'gh a slot 38 in the wall of the gt ide to normally maintain the associated tongue in depressed position. i

WVith the parts in the position shown in Fig. 1 a tripping cf the lever 8 will cause each draft-rod 16 17 to have a like simultaneous rearward movement, due to the lever 8 ccnnecti'ngwith the lever 12 in the manner shown. As the cross-head 16 cfthe former rcd moves rearwardly it passes under the associatedto'ngues 35, which are held in horizontal position against the tension of the springs 36 by the cross-head22 cf the draftrcd 22 being disposed thereunder, as shown in Fig. 6,-and its hook 16 is caused to engage the alining hock 16 of the draft-rod 22 and draw said rod 22 to the rear with it, thus effecting an oscillation of the member 24, which withdraws the wedge-block 26 from the trough 28 and forces the opposite wedgeblock 26 thereinand effects a consequent movement ofthe frog 4 to the :left, so as to guide a car upon the siding or diverging line As the draft-re d 17 moves rearwardly its hook is caused to escape that of the forwardly-mcving draft-rod 23, due to the cross-head cf the former riding upwardlyon the inclined ways formed by the lowered tongues 35 and finishing its stroke in the way 21, as indicated in Fig. 7, while the cross-head 23 finishes its stroke under said tongues, thus raising them to the elevated position shown in Fig. 6. After thecontact- 'piece'6 has passed bythe triparm 8 of the lever 8 said lever and the lever 12 and their attached rc ds 16 17 are actuated by the tension member 14 to return to their normal positions, so that the crcssheads of said rods lie in advance of the tongues 35 in theplanes cfmovenient of the cross-heads cf the associated draft-rods 22 23. As the lever 8 is next tripped for the purpose of throwing the frog 4 to the right to open the straightwaytrack, the movement of the operative parts, with the exception of the levers 8 and 12, is

vjust the reverse to that above described, as

the cross-head cf the rod 16 is now caused to ride up the inclined ways formed by the lower tongues 35 of the block 18, thus escaping contact cf'its'hock 16 with that of the rod 22, while the cross-head of the rod 17 travels under the raised tongues of the block 19 and its hock has contact with the hook cf the re d 23, thus drawing the rod 23 rearwardly, which effects an oscillation of the member 24 and drives the wedge 26 again within the trough to force the slide-blcck 27 and its attached parts to the right. It is thusapparent that successive tripping cf the lever 8 effects an alternately hit and miss action of the hook 16 of each draft-rod 16 17 with the so that first one wedge-block and then the other is driven into place within the trough member 28 to effect a desired movement of the switch-rod 30 and its connected frg or switch-point. It is also apparent that either wedge when in position rigidly locks the slide-block 2" against movement within. its trough, and if the switch-rod 30 is locked to the slide by a pin 32, as shown in Fig. :4, also prevents a movement of the frog or switchpcint relative to said slide. The preferable mode, however, is to permit the switch-rod to have a yielding movement relative to the slide, due to the action of the springs 33, so to form a spring-frog, which enables the flange of wheel passing over the frog in the direction toward wli sh it is pointing to force it over to open the channel, which channel is after ard closed by the elasticity of the springs.

The mechanism employed for opeating the frog 5 cf the second switch is shown as being positioned the rear of the mechanism operating the frog 4, and has the ends of its switch-rcd 30 connected by chains 39 to one end cf the lever 40, which is carried by a bracket 41 between the tracks adjacent the frog 5, and has its other end connected to such frog by the re d 42. The chains 39 pass through openings in the rails around suitable sheaves 43, as shown, and have their forward ends attached by turnbuckles 44 to the ends of a bar 45, which is pivoted ct its central part to the lever 40. With this arrangement the switch-rod 30 is preferably fixed to its slide-block 27 by pin 32 and the yield in tendency given to the frog by positioning coiled springs 46 on the bar 45.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifica-lions will occur to one skilled in the art nor do I desire to be restricted to the use of the mechanism shown and described in conjunction with a switch, as it is obvious that it can be used in numerous connections in which it is desired to communicate a reciprocatory or oscillatory movement to an object.
