To @ZZ whom, t nifty concern:
Be it known that I, CHARLIE LEE KEE, residingv at Portsmouth, in the county of Norfolk and State ofVirginia, have invented certain new anduseful Improvements in Railway-Switch Mechanism, of which the following is a specification.
My invention relates to certain new and useful improvements in railway-switch setting and locking mechanism in which means are provided under control from the train for -setting the switch and also for locking the switch to its set position (open or closed) during the entire time the train is passing thereover.
Primarily the invention has for -its obj ect to provide a device of this character of a very simple and effective, construction which can be readily and cheaply manufactured and which will effectively serve its intended purposes.
Generically, my invention comprises a switch-setting mechanism cooperatively connected with the switch-blades and including tripper devices arranged alongside of .the track, which devices are arranged to coperate with a train-carried device for operating the tripper devices to set the switch.
My invention also includes means coperating with the switch-setting mechanism and controlled by the weight of the passing train for locking the switch from movement during the entire timethe train is passing thereover, thus insuring absolute security to the train and preventing the switch jarring open or being tampered with while the train is passing thereover.
.I/Vith other objects in view than have been heretofore speciiied the invention also includes certain novel construction, combination, and arrangement of parts, all of which will be Iirst fully described and then specifically pointed out in the appended claims, reference being had to the accompanying drawc ings, in which- Figure l is a perspective view,showing my invention applied for use.- Fig. 2 is a top plan view thereof. Fig. 3 is a cross-section on the line 3 3 of Fig. 2. Fig. 4 is a side elevation of a section of track and switch, showing the manner in which the train controls the same. Fig. 5 yis a detail perspective view of the locking-bar attached to the switch. Fig. 6 is a similar view of the train-engaging latch-carrying bar that coperates with the `bar shown in Fig. 5. Fig. 7 is a detail perspective view, partly in section, of the tripper. Fig. 8 is a similar view of the train-carried tripper-engaging devices.
Referring now to the accompanyingdrawings, in which like numerals of reference indi-,
cate like parts in all of the figures, the main trackway is designated by the referencenumeral l, and the siding by the referencenumeral 2.
lav la designate the rails of the main track.- way, vand 2d 2fl the rails of the siding, as will be clearly understood by reference to the drawings.
The switch-rails in my presentv invention are designated by 3a 3a and are fulcrumed at one end, as at 3b 3b, as shown. Adjacent the switch-points 30 3C the switch-rails 3b are united by a brace 3d to give them proper strength. Connected with each switch-rail 3a 3a at a suitable place, preferably adjacent the switch-points 3C, is the switch-operating rod 4, which is pivotally connected at 4a to a bell-crank lever 5, fulcrumed at 5a adjacent the switch and track, the switch-rod 4 being connected to the arm 5b of the bell-crank lever, while the arm 5C of the bell-crank lever is pivotally connected at 62L to the switch-setting rody 6, which connects with the rtripper mechanism 7, presently again referred to.
To limit the movement of the bell-crank' lever 5, I place a stop 8 in such a position that when the switch-rails 3a are moved over to open up the switch to the siding, the stop 8 will engage the arm 5C of the bell-crank lever 5 and prevent further movement thereof.
To normally hold the switch-rails 3aL in their closed position to pass the train along the main-track rails la, I attach a U-shaped housing 9 to the switch-rod 4, through which a rod 10 passes, and the rod l() at one end is attached to a suitable support, which may be the rail la, as indicated at 10a. The other end of the rod l0 in practice may be threaded, and carries a barrel-shaped nut Il, provided with a squared head 11a. Surrounding the stem portion of the nut 1I and abutting the housing 9 is a coil-spring 12, which normally holds the switch-rails 3 in their closed position. The tension on the coil-spring 12 may be regulated by adjusting the nut member .1 1.
One of the switch-rails 3b carries a lug 3e, which has its edge beveled, as at 3f, andis adapted to be engaged by the flange of the car or locomotive wheel as the train passes off of the siding onto the main track to throw the switch-blades 3L 3a to their open position IOO IIO
to permit the train to pass off the siding onto the main line.
The tripper mechanism 7 comprises a housing 7, closed onits top by a slide 7b, that works in grooves 7 C in the housing ,7a and forms a closure therefor to prevent the entrance of dirt and water, &c., into the housing 7a, and in winter prevents freezing up of the tripper mechanism, so that it will always operate properly. rIhe housing 7EL is apertured in its front end, as at 7 d to permit passageof the switch-setting rod 6, which has its inner end 6b bifurcated and pivotally connected to the trigger 7e, which is fulcrumed at 7f at the bottom of the housing 7a, and to which the cover-operating rod 7 g is pivotally connected, as well as to the cover 7 b.
In practice, if found desirable, I may form the end of the switch-setting rod 6 within the housing 7 a with a lug 6x, and form a similar lug 7X on the trigger 7 e, between which lugs a coil-spring 7y may be secured to aid in returning the trigger 7e to its normal position, as well as serving as a buffer when the enginecarried trigger-operating arm engages the trigger, as will be more fully understood hereinafter.
In order to maintain the switch-blades 3a in either of their normal positions, it is necessary to provide a suitable locking means that will hold the switch-blades locked during the passage of a train thereover; otherwise the switch-blades might jar out of their set position and derail the train. Thus I have provided a locking means which comprises a locking rod or bar 13, secured to each of the switch-rails 3" adjacent the switch-bar 4, which rod or bar 13 passes through a block 14, which is provided with a slot 14a to permit passage of the rod 13 and is also provided with a latch-receiving aperture 14b in its top face to ermit passage of the latch-bolt 15 on the ocking-rail 16, presently to be described.
In practice I prefer to make the lockingbar 13 in two sections 13X 13y and pivotally connect the same together at 13%, so as to allow free movement of the switch-rails in setting them from one position to another, and to limit the movement of the bar 135 in each Adirection I provide stops 13m 13, as shown.
16 designates what I term a locking-rail, which I form in two sections, hingedly connected together at 16, and provided at its Aends with beveled portions 16b y1.6b on its up- 'per'face to permit the car-wheels riding upon the rails 16 in a manner presently explained.
[The rail 16 is arranged adjacent the switch mechanism with its pivotal connection in alinement with the block 14, and the rail 16 where it is pivotally connected is provided with a pair of ears 16C 16, between which is fulcrumed the latch-bolt 15, as at 15a, and
- the latch-bolt 15 has its lower end tapered, as
at 15b, so as to readily enter the apertures 13a in the locking-rod 13, as will be hereinafter fully understood. The locking-rail 16 is of suflicient length so that the wheels of the locomotive or car will always be thereon so long as a train is passing over the switch, and the rail 16 passes alongside of the main-line rail 1a and also the siding-rail 2a projecting in each direction a suitable distance.
In order to guide the rail 16, as well as to aid in supporting the same in position, I arranged U-shaped bearing members 17 at suitable intervals along the track to receive the rail 16, and at each end of the rail 16 on the under side thereof I provide extension members 18, likewise held in suitable bearing members 17, as indicated in the drawings, and at the outer ends of the extension members 18` on the under face thereof I provide lugs 18a,whichcoperatewithsimilar lugs 19, carried by blocks 19, arranged directly under the lugs 18a and adjacent the track; Between the lugs 18a and 19EL coil-springs 20 are held, and these coil-springs 20 serve to hold the ends of the rail 16 elevated ,above the level of the track-rails 1a and 2a, and to aid the springs 20 I provide additional springs 21 on each side of the hinged or fulcrum point of the sections of the rail 16, and lugs 16X 16x being provided at each side of the fulcrumpoint of the sections of the rails 16 to coperate with similar lugs 21X on blocks 21, ar-
ranged beneath the lugs 16X, and between which lugs 16x and-lugs 21x coil-springs 22 IOO trigger-engaging mechanism located on the locomotive between the pilot and the steamchest, and this mechanism consists of a cylinder 23, in which a piston 24 is moved to its downward position by air-pressure under control of the engineer and against the tension of a coil-spring 25, which passes around the piston-rod 26, that forms the arm for engaging the trigger 7e of the tripper mechanism when'the piston 24 has been forced downward by air-pressure.
So far as described the manner in which my invention operates can be bestjexplained as follows: Assuming a train to be passing along the main line toward the siding and it is desired that the train pass upon the siding,
IlO
the engineer then turns on the air-supply as the rails have been moved to their open position and before the piston-rod or arm has disengaged the tripper mechanism the pilotwheels of the locomotive will have engaged the rails 16 and depressed the same, thus carsing the locking-bolt 15 to enter the outer aperture 13"L in the bar 13 and lock the switchrails to their set position so long as the wheels of the train are on the rail 16, and as soon .s the last car has passed over the switch and the rear wheels thereof have passed off of the rail 16 the springs 20 and 22 again raise the rail 16 above the level of the track and permit the spring 12 to return the switch-rails to their normal position to open up track-trahie across the switch for the main line. Now assume the train to be passing toward the switch and it is not desired that the train pass on the siding, then the engineer does not cause the piston 24 toy operate, and hence. the locomotive-carried arm will not engage the tripper mechanism. The wheels of the car, however, as soon as they ride upon the rail 16 will depress the same as before and this time cause the locking-bolt 15 to enter the inner aperture 13a of the rod or bar 13 and lock the switch in its closed position until a train has passed thereover, as before. Should a train be coming along the main line from left to right in Fig. 2, the wheels of the train will ride upon the bevel portion 165 of the rail 16 and depress the same to lock the switch during the time the train is` passing thereover. When the train on the siding passes over the switch onto the main line, the wheels of the locomotive will engage the member 3e and open the switch, and as soon as the switch has been opened the wheels of the locomotive will ride upon the rail 16 and depress the same to lock the switch open until the train has passed off of the siding onto the main line again, it being understood that a similar switch is provided at each end of the siding.
Whenever it may be found desirable lv may use my improved lookin means in connection with a tower-operate switch-setting mechanism by simply connecting the switchsetting rod 6 with the lever in the tower operators' chamber in any approved manner; although I prefer to use the automatic setting mechanism hereinbefore described.
From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation, and numerous advantages of my invention will be readily understood by those skilled in the art to which it appertains, and I desire it understood that many slight changes in the detail, combination, constrrction, and arrangement of parts may be made Without departing from the scope of the appended claims or the spirit of the invention.
