.RAlLWAY-SWITCH.
SPEGIFIGATION forming part of Letters Patent 0. 702,522, dated June 17, 1902.
Application filed December 16, 1901. Serial No. 86,121. (No model.)
To all whom it may concern:
Be it known that 1, WILLIAM 0. W001), a citizen of the United States,residing at-New York, in the county of New York and State of- New Y0rk,have invented certain newand use- The invention relates to that class of switches wherein a vibrating or oscillating tongue is used for shifting the course of a line of track into a branch ,thereof, or-viceversa, which tongue terminates at the base into a switch-center, at or near which point it is pivoted orhinged,ashereinafter more thoroughly described.
The special features of the invention are found in and around the pin which forms the central part of the hinge, first, in the manner of fastening the said pin in the tongue, and, next, in the manner and means whereby the pin is held in proper position, (vertically,) while beingallowed to work (in the bindingbox) with sufficient freedom to permit of shifting the point of the tongue from side to side without difficulty. I s
In the accompanying drawings, Figurel represents a longitudinal section ofthe device on line X X Fig. 2. Fig. 2 represents in plan a portion of the switch-center and of the bed upon which the tongue (partially.
shown in dotted lines) is located and where it is secured at one end byparts indicated in full or by dotted lines.
Referring to the details represented in the drawings and indicatedbyletters of reference, D is designated as a gravity-wedge, which is guided partially by side walls as well as by the vertical face of the end wall, against which the back of the said wedge slides and reaotsin the performance of its duties, as hereinafter. described. i This wedge is inserted through opening N into recess 0, which opening, on account of existing conditions, is confined within dimensions which would practically admit'of nothing larger than the wedge and contiguous parts thus shown. Hence it is that the box F, which is here employed for holding the pin in the desired position, is made in two pieces or is suppliedwith a loose back E, which imparts the force from wedge Dias applied to the back F and so on to the pin G in the manner thus plainlyindicatedfi v The recess 0 is'forme'd by the four vertical walls'which surround'itin conjunction with theitop and bottom section's P and Q, respectively, and which latter parts serve to hold th e pin G loosely(as intended) in a vertical position, but which pinis still dependent for its required stability up'onthe force exerted throughthe parts D E F,being thus urged 'to the support of said pin through the falling tendency of wedgeD through its own gravity.
This'beingsoclearly the case demonstrated in practice and wherein this desired effect is so cheaply and simply produced, I make it a point to bring this part of the description to where my claim to the invention will be established.
It will be understood that all the parts herein described as new are adapted within the body of a railway-switch O of no unusual pattern, wherefor'special description and illustration thereof are omitted here.
The pin G enters the tongue A from its lower surface, as shown, and istherein rigidly held by means'of transverse pin S, reinforced by Babbitt or other suitable metal, which is poured around the pin after the same is in place, and for this purpose an annular chamber is provided in the tongue, which coincides with a depression in the pin, as shown; but in this connection it should be stated that one or the other of these expedients may be dispensed with under some circumstances. When the metal is used as above indicated,
the pouring maybe done through passages B B B", (shown in dotted lines in Fig. 2,)
and when removal of the pin is necessary the metal may be heated and run off through the same passages.
It will be observed that as the wedge D is entirely dependent upon its own gravity for the automatic adjustment of the boxF against the pin G, and being constructedfonanangle which'does not admit ofjamming many-a preciable extent, the;remo'val.. ofv-=the},said wedge from the top canalwa'ys b effected without difliculty through the use of a hookbar introduced through the passage U. (Shown in dotted lines in Fig. 1.)
In justice to the state of the art I deem it proper to make mention of the fact here that in Patent No. 395,987, granted to me on the 22d day of March, 1887, designated Switch for street-railways, I made use of a gravity wedge in my provisions for taking up slack.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, isv 1. In a railway-switch, a hinge-pin entering from the lower face of the tongue and extending to a point below its upper face, and means for fixedly fastening said pin into the tongue to turn with the swinging movement of the tongue, substantially as described.
2. In a railway-switch wherein a vibrating tongue is used for shifting the course of a track from a single track to a branch thereof, a vertical pin entering from thelower face of said tongue and extending upwardly to a point below the upper face of the tongue and having its upper end concealed by said tongue, and means for fixedly fastening the said pin to said tongue to turn with the swinging movement of the tongue, substantially as specified.
3. In a railwayswitch, the combination with a tongue having on its under side a socket or recess, the end wall of which is located in a plane below that of the upper face of the tongue, and a pin inserted in the socket or recess, and means for fixedly fastening the pin in the socket or recess to turn with the swinging movement of the tongue, substantially as and for the purpose set forth.
4. In a railwayswitch, the combination with a vibrating tongue having a recess or socket in its under side, the end Wall of which is in a plane below that of the upper face of the switch-tongue, in combination with a pin for connecting the hinge-pin to the switchtongue, a vertically-adjustable bearing-box, and an adjusting-wedge, substantially as set forth.
5. The combination withavibrating switchtongue having a socket or recess in its lower face, the inner wall of said socket or recess being in a plane below that of the upper face of the tongue, said pin at that point which enters the socket or recess being formed with a groove, and Babbitt metal let into said groove to lock the pin in place, substantially as set forth.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
WILLIAM C. WOOD.
