OSCAR W. ASHLEY, OF RALEIGH, WEST VIRGINIA.

To all whom t may concern.'

Be it known that I, )soan lV. Asumir, a citizen ot the United States, residing at Raleigh, in the county of Raleigh and State of Vest Virginia, have invented new and useful Improvements in Railway-Switches, oft which the 'following is a specification.

This invention relates to certain nov-el and use't'ul improvements in railways oit the character en'lploying a rack rail, and has particulaiI application to .means for automatically switching the rack rail at the unction oit the main line and branch line o't' the railroad.

As is usual in railways of this character it is imperative that the driving mechanism et the truck should have continuous engagement with the rack rail, especially while passing over a switch or at the junction oil the main and branch lines. Consequently, the ack rails extend over the switching rails to provide for such continuous passage, either along the main or h anch line, and as a result such overlying sections oit' the rack rail must be shifted at predetermined times to permit the truck to travel along a selected line. Ordinarily the switching sections of the rack rails are either litt-ed and shifted manually, or are thrown by a simple -form o't switch throwing mechanism requiring the personal attention ot the operator. ln either event, considerable loss of time and labor results, in addition to the liability oit' the operator tailing to throw the switch r at the proper time, which Yfailure, lrerulently results in disastrous accidents and wrecks.

ln the present. instance, it is my purpose to provide an arrangement whereby the switch may be thrown automatically to permit the motor to travel in the direction desired without requiring or relying upon the personal attention oit an operator.

Still another object ol my invention is to provide a novel form of rack rail which will embody in its construction the desired features of strength, durability and elliciency.

li`urther objects of this invention will appear as the following specilic description read in connection with the accompanying (ilrawing, which forms a part oit this application, and in whichlligilre l is a top plan view. Fig. Q is section on lthe line 2-2 o'tI Fig. 1. Fig. is a bottom plan view with a portion of Specification of Letters Patent.

Fig. (i is a perspective view olf one oi the pivoted rack rail sections. Fig. 7 is a section on the line 7-7 of Fig. 3. Fig. S is z. detail perspective view o't' one ot' the tripping levers. Fig. 9 is a section on the line J-MS) o't` Fig.

Referring more particularly to the drawings, the numerals 1--1 indicate the main line rails, while the numerals 2 2 indicate the branch line rails which communicate with the main line rails through a switch whose rails are indicated at 3-3 shown to be in the nature ot switch points which are pivoted at t and 5 to one oit the switch track rails and to one oi the main line rails. These switch points er rail sections 3-3 are connected ley a spreader bar (l and it will, ol course, be understood that when they are swung in one position as, for instance, into the position shown in Fig. l, the branch track is cle-.tr for the train to pass thereover, while when such switch points are swung to the opposite position, the train will be carried directly through on the main line rail.

Arranged between the main line ails at a point adjacent the switch is what may be termed a rack rail lirog 7 which consists of a metal plate having a plurality of openings S therein o'l.E gradually increasing length so as to merge into the diverging series of openings 9 and ll). The former series of openings is parallel with the main line rails, while the latter series ol openings is parallel with the branch line rails. lhe end of the lirog having the series l() therein is considerably longer than the end having the .series t) therein and has pivolally connected to its terminal one el a pair ol rack rail sec lions 1.1 and l2. The latter rack rail section is pivotally connected to the branch line rack rail 13 and has its lree end abutting the free end o't the section ll, as will be hereinafter dcscribml, the point ol connection between the two being immediately over the center oil the main line rail, as will be hereinafter described. The end of the frog haring the series S) therein has pivoted to it one o'l a pair o't piroled rack rail sections l-t and l5, the latter el which is pivoted to the main rack rail 11G and has its :lree end abutting the :tree end el the pivoted section 14, the junction between the two occurring immediately over the center of the branch line rail 2, as will be hereinafter described. These pivoted rack rail sections or throw rail sections are all similar in construction and, therefore, under the circumstances, a description of one will sutlice for all.

Referring now to Figs. 6 and 7, wherein the throw rail is shown in detail, it will be seen that such rail section comprises a top rack member 17 cut to a predetermined size and having its ends provided with eXtensions 18 and shoulders 19 for a purpose to be hereinafter described. The bottom of the rail is also formed of a section of rack rail 29 eut to the proper size and having its ends bent up, as shown at 21. The top and bot-- tom sections are connected together by separate pieces of channel iron 22 which are inserted between the upper and lower rack rails 17 and 20, the whole being secured together by rivets or in any other suitable manner, whereby each rack rail section comprises aunitaryl structure. Secured to one side of each section is a tripping plate 23 which is provided with a horizontally projecting web 24 having the cam faces 25 and 26 formed thereon. The throw rail sections are pivoted at 27 to extensions 2S formed on the main and branch line rack rails 13 and 16, as shown, and when their free ends abut each other, the extensions 18 engage the shoulders 19 in such a manner that the pull exerted upon the throw rail sections will be communicated directly through the eXtensions and shoulders to the main rack rails. At the same time, a practically continuous rail is produced owing to the fact that the throw rail sections are limited by the rail, as will be hereinafter described, and the eX- tensions produce an opening between the two for a spur gear tooth to enter.

ln order that the throw rail sections may be automatically opened vup or have their free ends separatedto provide a clear track over the main or branch rails, each set or pair of throw rails 11 and 12 or 14 and 15 are connected by spreader bars 29 which are pivotally mounted upon studs 30 depending from rail clips 31 which are secured to the base flanges of the rails. These spreader membersl comprise a pivoting head 32, through which the stud 30 extends and oppositely extending arms 33 integral with the head and having upward bends so as to bring their ends into position to engage the free ends of the throw rail section. The free ends of the spreader arms carry adjustable pivoting bolts 34 which slidably engage longitudinal slots 35 in pivoting strips or plates 36 which are adjustably connected to the under side of the throw sections, these plates having. raised ends, as shown in Fig. 4, which are slotted so as to adjustably receive the attaching bolts 37,

whereby the plates may be adjusted transversely across the throw sections. This adjustment is made in order that the free ends of the separate throw sections may properly register with each other when alined, the plates abutting the rails, over which the throw sections extend to properly limit their movement. Each spreader arm also comprises an operating lever 38 to be hereinat'ter described. These spreader arms are pivoted to separate the free ends of the throw sections by means of suitable mechanism to be now described.

Pivoted to one of the supporting ties 39 is a trip lever 40 having a laterally eXtending web 41 which overlies the rail when set for operation and is provided with a cam face 42 to be engaged by the wheel flange of the iirst truck passing over the rail. The ends of these trip levers are bent laterally on a curve as shown at 43 so as to insure proper engagement of the wheel flange with the cam face 42. The lever shown at A for the branch line has the end opposite the web 41 provided with a slot 44 to engage a pivotal bolt 45 secured to the central portions of a bridle bar 46. `This bridle bar has its inner end connected to an operating lever 47 which is centrally pivoted, as shown at 48, to one of the ties. On the side of the lever adjacent the lever A is pivotally connected a link 49 which in turn is pivotally secured to the arm 38 of the spreader bar as shown at B. The opposite side of the lever is connected by a link 50 to the arm 38 of the spreader bar, shown at C. At the opposite end of the lever from the lever A, a slot 51 is formed in which is received the pivot bolt 52 which connects the bridle bark 53 to said lever. There is also pivoted to this end of the lever 47 a link 54 which is provided at its opposite end with a pivot bolt 55 engaged with the slotted end of a tripping lever 56 which is pivoted upon a tie, as shown at 57, and is provided with the usual flange engaging web 53 at its end, the levers 56 and 40 being identical. Each bridle bar is connected' at its outer end to a lever 56 provided with a slotted F-head 57 and pivoted to a bracket 58 carried by one of the ties. Pivoted to this Vlever by the same pivot bolt which connects the same to the bracket is a counter-weight arm 59 having a weight 60 arranged on its outer upper end. This arm 59 is limited in its movement by the end walls of the slot in the T-head and may be adjustably limited by inserting pins in the holes 61 formed in the T-head therefor. The spreader bar 6 is shown connected to a bridle bar 62 which is provided with a similar locking mechanism, as described previously for the bridle bar 46 at B.

Tn the operation of the device, we will assume that the throw rails have been set to the position shown in Fig. 1 by a train passing in the direction of the arrow a and that it is desired to pass a train along the main line rails in the direction of the arrow Z1. The switch is then thrown so that the ar point will be separated 'from the main line rail and the near point engaged with the switch rail, as is readily understood. A car passing over the switch point of the main line rail would then have the irst wheel of its truck engage the lever 5G and through the link 54, lever 47, link 49, and spreader arm B turn the spreader arm upon its pivotal point and separate the free ends of the throw rails 11 and 12. If the train were traveling in the direction indicated by the arrow c, the cam surface Q5 of the web 24 on the throw rail section 12 would be engaged by the wheel so as to throw this section toward the left and through the spreader bar, throw the section 11 toward the right. Either of these operations would throw the lever 40 against the track so that a train traveling over the branch rails in the direction of the arrow a would operate upon said lever and through the bridle bar 4G, the lever 47, and link 50, operating the spreaderl bar, shown at C, to throw the switch points 14 and 15 to the position shown in Fig. 1. In case the wheel does not strike the cam surface of the web 24 on the throw section 12 with sutticieut Ytorce to operate the parts, the flange of the wheel will engage the cam surface 26 upon the adjoining throw section 11 to fully operate the parts. The T-heads 57 on the levers 56 are only thrown to a position su'Hiciently far to carry the lever 59 beyond center so that the weight will drop to the opposite end of the slot or to the other stop and lock the parts in operative position. It the throw rails have been properly alined by the acl tion of the lever mechanism, the weights when dropped will cause a proper alinement of the same so that the spur gear wheels on the motors can not by any possible means, run ott the rack rails.
