LA Summe? peiling action of the wires from that station until it is delivered to the turn-plate-track, travel around this until it reaches the wire extending to the other station, which will be kept normally closed as hereinafter explained, and along t-his latter it will run until it arrives at its destination. In order to go round the turn-plate, however, it is necessary that one side of the carrier should be cut away, as shown, to pass the body of the plate. This, however, forms no part of mypresent invention, having been used heretofore in the Barr system. In turning the curve there will be a strong tendency of the carrier to swing outward by centrifugal force, and this, if not lessened, will result in its reaching the other and closed track, at an inclination to the vertical yand in passing along that track with a pendulum or staggering movement. To provide against this therefore, I arrange a double guard, preferably a skeleton guard, around this curve. This guard is composed of two or more brackets, D2, secured to the bottom of the plate, thence bent obliquely downward until reaching a point almost perpendicular below the edge of the plate, or track thereon, but sufficiently within the perpendicular to permit the closed passage of the inner side of the carrier, then vertically downward, to the depth of the carrier, then horizontally to its thickness, then vertically upwardfto a point above the turnplate, thence over horizontally a sufficient distance to overhang the turn plate and track and then downward again a short distance, to receive an inner guard, d', at such distance within the track as to come in contact with the upper face of the carriage and curved concentric with said track so that as the carriage speeds around, the upper inside face thereof may rest against this guard. A second guardwire, cl2, outside of and somewhat below the plate track and concentric therewith, is se# cured to the outer vertical arms of the bracket to come in' contact with the outer face of the carrier below its contact with the track, as it is speeding around and prevent said carrier from swinging outward,.while a third guard-wire, cl3, may be applied to the inner perpendicular arms of said brackets. This inner-guard, cl3, is to steady the carrier that its lower end may not swing inward when restrained from swinging outward.

The lower ends of the guard-brackets are each formed of two parallel bars, E, between which can pass slides, E having anti-friction rolls', e, at their rear, which travel on the edges of the guide-brackets and in front being connected respectively to the upper and lower track-wire. Normally these slides are drawn together by powerful springs, e', one end of one spring being secured to the upper slide, and carried thence down past the other and secured at its lower end to a pin e2 at the lower end of the guide-bracket, while one end of theother spring is secured to the lower slide and thence carried to an attachment, e3,

at the upper end of the guide-bracket, thus obtaining sufficient length in the springs to insure powerful and lasting contraction so that after the slides have been spread apart to diverge the track wires and impel the carrier from one station, they shall, as soon as released, Hy back, bringing the track-wires at that station parallel with each other so as to afford no obstruction to the return of the carrier when impelled from the opposite station.

Any suitable device may be used for spreading the slides apart from each other, that will permit them to return to position under the stress of the spring, but I find it convenient to attach cords, to both slides, that one, F, attached to the upper slide being carried ove-r a pulley, f, above said slide, and then led down until it is brought alongside the cord, F', from the lower slide, when the two are united by a handle, f', depending within convenient reach of the attendant. Thus a direct downward pull will depress the lower slide, but will raise the upper slide, owing to the interposition of the pulley, and spread apart the wires, and as soon as the cords are released from the grasp of the hand, the springs will pull the slides and track wires together again.

For the purpose of assisting the track-slides to their position, a curved plate spring, G, may be applied to the back of the guidebrackets, curving out from the center towardy the ends and underlying the anti-friction rolls on the slides so that when the latter are drawn apart they shall press down the spring flat against the bracket, but when relieved, the spring may, in returning to the normal, exert a wedging action on them to carrythem back toward the center.

In order to obtain the necessary expansion and contraction in length of the tracks in the operation of the spreading devices, a coiled spring is connected at one end to the end of the track-wire and at the other end to its appropriate slide, so as to expand as the slide is moved away from the opposite track-wire and contract as it is moved theretoward. Preferably, and for the further purpose of taking up slack, both in the track wires and guys, this spring is made as a sort of turnbuckle, shown in one form in the second tigure, but in a somewhat different form and in detail in Figs. 11 to 13 of the drawings. In the first form the single coiled spring heretofore mentioned is secured at its ends to the slide and the wire respectively, by eye-rods, H, which have enlarged hubs, h, as in Fig. 14 fitting quite snugly the internal diame ter of the coil and provided with threads or spiral wings, h', which enter between the coils and can be screwed therealong by turning the rod, thus making the effective length of the spring longer or shorter at will. In the second form, however, two coiled springs, h2, are used, each receiving at one end one of the eyerods, H, and hubs with its flange or wing and at the other end, or the meeting ends of IOO iIO

the two coils, a single rod or spindle, H', having at each end a spiral flange or wing, h3. In this construction the springs must be right and left and the spirals on the central rod must be correspondingly turned, thus when the end rods have been inserted and attached to their respective point-s of support, for instance one to the spreading slide and the other to the track-wire, the central rod or spindle can be used to bring the coils nearer together or farther apart Without disturbing said other attachments. This spring turnbuckle by itself I do not intend to claim herein, having made it the subject matter of an application iiled by me on the 26th day of November, 1892, Serial No. 453,180, for Letters Patent for improvements in turn-buckles.

Vhile I have illustrated and described the turn-plate in this case as if used simply for turning a corner in a horizontal line, it is to be understood that by slight modications in position it may be used for surmounting an elevation; and While also slide-blocks moving in a vertical way and normally held together by springs have been described with means for momentarily spreading or diverging the wires `at thesending station and normally closed at the receivingr station,it is to be i'urther understood that I do not limit myself to any specific means whereby two .line wires extending from station to station, or interrupted midway by a track, are held normally apart momentarily only at the sending end,

nor yet do I limit myself to imparting positive movement to both wires at the sending station, since it is evident that one wire maybe fixed while the other is moved as in systems heretofore used, but

What I do claim and desire to secure by Letters Patent is:

1. The combination substantially as hereinbefore set forth, with the turn-plate, of the skeleton guide formed as described, of brackets secured to the bottom of the plate, thence bent obliquely and perpendicularly downward, horizontally outward, vertically upward over and downward, and having the guideribs or guards attached thereto at about the points stated, above and below said plate.

2. The combination substantially as hereinbefore set forth, with the turn-plate, of wires leading from each station to the track therein passed through the extreme ends of said track and returned to their respective stations, and spreading devices at each station for the wires.

3. The combination substantially as hereinbefore set forth, with the track-wires, of the guide-brackets, the slides moving thereon, the springs arranged to hold said slides against each other at the center of the bracket and means for spreading said slides momentarily apart.

et. The combination substantially as hereinbefore set forth, with the track wires, the guide brackets, and the spreading slides moving thereon, of the coiled springs independently connecting each of said track-wires directly to its respective spreading slides.

5. The combination substantially as hereinbefore set forth, with the track wires, the guide-brackets and the slides moving thereon of the spring-turn-buckle connecting said track-wires and the slides.

6. The combination substantially as hereinbefore set forth, with the track-wires, the guide-brackets, the slides moving thereon and their anti-friction rolls, of the springs extending from the upper slide to the lower end of the guide-bracket and from the lower slide to the upper end of the guide-bracket.

7. The combination substantially as hereinbefore set forth, with the track-wires, the guide-brackets and the slides moving thereon of the cord leading from the upper slide over a pulley and thence down and the cord leading from the lower slide to the first named cord and united to it by a handle whereby the slides can be simultaneously spread.

8. The combination substantially as hereinbefore set forth, with the track-wires, the guide brackets and the slides having antifriction rolls moving along side guide-brackets, of the curved spring arranged along the back of said guide-brackets and traversed by said anti-friction rolls.
