Application filed May l5, 1884. (No model.)
'anism in such manner as to insert guard-rollers,which are mounted in their ends intothe grooves in the rails, orto withdraw them therefrom.
My invention consists in asingle rigid arched arm carrying rollers in its ends and mounted under the truck, and in suitable mechanism by which said arm is lowered and turned to extend .transversely and insert its rollers inthe grooves of the rails, and by which it is turned again to withdrawvits rollers, and is raised to a position parallel with and above the plane of the rails, all of which I shall hereinafter fully explain.
The object of my invention is to prevent derailment of the cars or of the locomotive to which the devices may be attached.
Referring to the accompanying dra-wings, Figure 1 is an end view of a car or locomotive, showing my safety-guard applied, the rollers being withdrawn from the grooves inthe rails. Fig. 2 is a similar view showing the rollers inserted inthe grooves. Fig. Sis a side view showing a modified mechanism by which the guard-arm is operated, the rollers being in position. Fig. 4. is a similar view of same, showing the arm raised and the rollers withdrawn. Fig. 5 is an end view of same.
A is a portion of the frame of a car or locomotive mounted on wheels B.
C are the rails, having grooves c.
Secured to frame or car A is a rigid metal frame, J, through which 'and through the car A is passed a spindle, D, to the lower end of which is firmly secured a rigid arm, E, having downwardly and outwardly turned ends, in which the guard-rollers c are mounted. rIhe shape of this arm is curved upwardly or arched, as shown, in order to avoid obstructions, such as the raised center of the roadbed or crossy `roads, when the arm is lowered to insert its l rollers in the grooves of the rails, as shown in Fig. 2. i
Upon frame J is mounted a curved inclined plane or cam, F, upon which an arm or pin, d, secured to the spindle D, is adapted to travel, whereby said spindle is raised or lowered. A shoulder, f, on the top of the cam limits the upward movement of pin d, as in Fig. l; and a pin, f limits its downward movement, as in Fig. 2.
Upon top of the spindle D is a cranlcarm, G, to which is pivoted the end of a bent rod, II, the other end of which extends backwardly and parallel with frame A, and is secured to the short arm of an elbow-lever, I, pivoted to said frame. The transverse portion of the bent rod H passes by an inclined plane or-cam, K, which guides it. Vhen the long arm of lever I is depressed, whereby, as in Fig. l, its short arm is raised, the bent rod Il is carried up, and thereby pulls on the crankarm G, turning thespi'ndlcl) and arm E, said spindle and arm at the same time rising by reason of the arm d, traveling up the cam F,whereby the arm is turned parallel, or nearly so, with the rails, and is raised up out of the way. Vhen the long end of lever I israised, as in Fig. 2, the bent rod II is depressed and forces the crankarm G away to turn the spindle and carry the arm E across the track, and at the same time 'lowers it to the plane of the grooves in the rails into which the rollers project; but I do not confine myself to the mechanism thus far described for accomplishing this movement of the arm E.
In Figs. 3, 4, 5 Ishow amodified mechanism. The spindle Dis provided with the crank-arm G,which in this casc is under instead of above car A. Vith this is connected a rod, L, the other end of which is pivoted to the lower end ed to engage with a rack, fm. rIhe movement ofthe lever M turns the spindle D and the arm E transversely, as in Figs. 3, 5, or parallel with the rails, as in Fig. 4; but, in order to raise the arm when turned away and to lower it when turned across, I have the elbow-lever N pivoted by one end or arm to a short `bear1- ing, n, under car A. Its other arm is bifurcated, and embraces the spindle D- under the collar or head g of the crank-arm G. At its angle is a pin or stud, o, upon which is slotted of a lever, M, pivoted on the car A, and adapt- Y IOO a bar, O, the other end of which is pivoted to the lower end of lever M. The movement of the lower end of this lever toward the spindle forces the bar O down until it is limited by its slot, as in Fig. 4, when it presses against the studo and forces the elboW-leverN to raise the spindle. Vhen the bar O is withdrawn, the weight of the spindle causes it to drop, and it is stopped by any suitable means above, as by a collar, p.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. Inasafety car-truck, arigid arm supported under the truclgand having rollers mounted in its ends, in combination With a mechanism by which said arm is lowered to carry its ends down to the plane of the grooves in the rails of the road-bed, and turned transversely to insert its rollers in said grooves, and by which it is turned parallel with said rails to free its rollers therefrom, and raised above-the plane of the grooves therein, substantially as herein described.
2. In a safety car-truok, the bent or arched arm E, having rollers c in its ends, and the spindle D, upon Which said arm is mounted, in combination with a mechanism by which said spindle is lowered and turned, to drop and turn the arm transversely to fit its rollers into the grooves in the rails of the road-bed, and is turned and raised to free the rollers from the rails and raise the arm, substantially as herein described.
3. In a safety cartruck', the rigid arm E, having rollers c in its ends, and the spindle AD, upon which the arm is mounted, in combion the spindle, adapted to travel onthe caml between the shoulder f and pin f, the crankarin G on top of the spindle, the bent rod II, inclined guide-plate K, and elbow-lever I, all arranged and operati ng substantially as hcrei n described. p
In Witness whereof I have hereunto set my hand.
