Specification of Letters Patent.

Patented April 24, 1906.

Application filed October 21. 1904- Serial No. 229.427.

T0 aZZ whom it may concern:

Be it known that I, AL'oUsT SCIIULZ, a citizen of the German Empire, residing at Podeuch, in the Province of Pomerania and Empire of Germany, have invented certain new and useful Improvements in (ar(ouplings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to car-couplings; and the object of the invention is to provide means whereby the coupling and uncoupling of cars may be effected by a person standing at the side of the car and without going between the ends of the cars to be coupled. i

The invention consists in the novel construction, combination, and arrangement of parts hereinafter described and claimed.

My invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation, partly in section, of the ends of the platforms of two cars With my improved car-coupling applied thereto. Fig. 2 is a top plan view of the same. Fig. 3 is a top plan view of one of the coupling-hooks, and -L is a sectional view on the line I 4 of Fig. 3.

In the several figures of the drawings like letters of reference indicate like parts, and A A designate the platforms of two cars, each of which is provided with coupling members, the coupling members on one car being of the same construction as the coupling members on the other car.

It will be only necessary to particularly describe one coupling member, and for the sake of a clearer understanding of the construction of the parts I have applied a primc-mark to each of the reference-letters applied to the coupling members which are secured to the platform A. The coupling member on each platform comprises a main draw-hook a and a spare hook Z, the former sustaining the traction of the coupling under ordinary circumstances, while the latter is provided as an adjunct to sustain the traction of the coupling in the event of breakage of the connec tions between the main couplings. The draw-hook a terminates in a drawbar I). The draw-bar passes through the end of the platform, of the car, and its threaded end screws into a nut (Z, which is revolubly mounted within the platform. The nut (Z carries on its rear end a worm-wheel c, that meshes with a worm e, carried on a shaft f,

and by turning the shaft f the nut is caused to revolve and move the draw-bar in or out, as may be desired. An L-shapcd arm It: is slidably mounted on the bottom of the platform, and said arm is provided with a slot '11, in its vertical arm, which receives a pin 1) on the end of one of the coupling-loops hereinafter described. A lever g is pivotally mounted on the bottom of the platform and is connected to the arm Zr, and by means of its lever the arm /r is moved forward and backward to effect a similar movement of the coupling-loops.

The coupling-loops are designated 1- s t, and the innermost loop r is formed with a slot '10, through which passes pins :11 a, that project from the sides of the main draw-hook (l and pass through the bifurcated end of the spare hook Z. The coupling-loops are pivotally connected at the juncture of the loops 1' and s to a linkrod 'i, which is connected at its other end to a crank I/ on a lock-shaft l1, mounted on the bottom of the platform. Each of the cmipling-loops r .9 is provided with a lug 2 on one end, and these lugs 2 serve when the coupling-loops are raised to maintain the loops 3 t in alincmcnt with the loop '1'. The link i is provided with a flap 'm, which bears against a guide-bolt (1, carried by a movable bar 0, mounted in the spare hook Z. The bar 0 is provided with a connecting-rod p, which when at rest rests on the head of the book, as shown in Fig. 1.

The coupling of two carriages is effected in the following manner: The shaft 72 is made to turn by means of a lever placed on it, the link-rods i, which are sccurely connected with Z1, lift the coupling-links 'r, s, and t up ward. In order to now swing them into the opposite hook, the coupling-links are drawn as far back with the lever g by means of the rectangular arm A as is permissible by the opening in the link 11, thus carrying the coupling-loop upward before the opposite hook, and the brakeman is then able by a backward pressure of the lever g to carry the same clear above the hook and drop it into position, the tension then being effected by the wormshaft c. and the worm-wheel c. As is shown by Fig. l, the spare hook Z is hereby lifted so high upward that it is possible for it to swing into the couplingloop on the carriage standing opposite, and this is done in the following manner: ith the upward movement of the main coupling the hook Z, which when at rest is hanging free between the linkrods'i pcrpen- 5 brought into a sloping position.

20 the coupling-loop t.

dicularly to the draw-bar, is at the same time carried along by the flaps m, fastened onto the links i, which, striking against the guidebolts q 12, Fig. 1, fastened on the bars 0, are If the spare coupling is to be swung into position, the same procedure as with the main coupling follows. The coupling-loops on the carriage standing opposite are lifted upward by means 10 ,of h, the link 25 strikes against the lower part (i. 6., the cross-bar p) of the bar 0 and lifts the same as far as the guide-bolts 9 allow, the latter running in two slots of the hook Z, dragging over the curve of the flaps m, owing I 5 to the centripetal power of the hook. The

sliding of the bolts Q over the flaps m is prevented by the coupling-loop t not permitting a further sinking of the hook, as the hook, owing to its own weight, falls by itself into Hereupon the lever fixed on h is released, the coupling returns to its position of gravity, and the spare hook Z is continually held by the flaps m in the position shown in Fig. 1. The uncoupling is effected vice versa.

I claim- In a car-coupling member, the combination with a main draw-hook mounted on the platform, coupling-loops pivoted together and to said draw-hook, a link connected to said cou ling-loops, a rock-shaft mounted on the platform of the car and having a crank attached to said link, a spare hook pivotally mounted on. said main hook, a bar movably mounted in said spare hook and pins projectin laterally from said bar and engaging said aps carried by said links when the link is raised.

In testimony whereof I affix my signature in the presence of two witnesses.
