SPECIFICATION forming part of Letters Patent No. 376,734, dated January 24,1888.

Application filed October 6, 1887. Serial No. 251,644. I (No model.)

To all whom it may concern.- x Be it known that I, VAN R. DAVIS, acitizen of the United States, residing at Temple, in the county of Oarroll'and State of Georgia,

5 have invented certain new and useful Improvements in Automatic Oar-Couplers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled-inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and'figures of reference marked thereon, which form a part of this specification. My invention relates to certain improvements in car couplers; and it has for its objectsv to provide for automatically coupling and uncoupling the cars, so as'to prevent theneces sity of a road-hand from entering between the.

cars, and thus preventthe accidents attendant upon the ordinary methods of coupling and uncoupling. These objects I attain by the means illustrated inthe accompanying drawings, in which r Figure 1 is a bottom plan view showing the couplerjoined. Fig. 2 is a top plan view of the coupler detached. Fig. 3,is a side elevation of the same, and Fig. 4 is'a side elevation of wheel-shaft and chain connection.

The letter A indicates the truck of the car, and B the draw-bar, secured thereto in the ordinary manner. The 'draw-bar does not extend quite to the end of the truck, and at its outward end it is slotted horizontally, as shown in the drawings, the slot forming a recess wherein the shank of the coupling-link G is pivoted. The outward end of the draw-bar is squared for about two-thirds of its width, as indicated by the letter a, the remaining portion of its width being rounded, as indicated by the letter I) in the drawings. The coupling link at the part adjoining the shank is shouldered, as indicated, about two-thirds of the width of the shoulders being squared, so as to set firmly against the squared portion of the V of the link from sudden shocks when the cars are stopped,-which would be apt to injure or.

break it. The curved portions of the respective parts of the draw-bar and link permit the link to move laterally for the purpose of coupling and uncoupling. The link at its'forward end is hooked, as indicated by the letter 0-, so

link of the connecting car. each link is beveled, as indicated by the letter each other laterally until the hooked portions pass and are in position to be engaged. The

engagement'is eflected bymeans of the fiat)- springs e, which press the links'toward each other. T g

To the outer ends of the link is secured an eye or'staple, D, from which extends a chain to an upright shaft, E, which is journaled in 5 above the floor of the car and hasa hand-wheel {p at its uppenend, by which it may Ice-turned;

the truck of the car. The said shaft projects \The said shaft is also squared at g, and has a ratchet-wheel secured to it at that point,which 7o.

is engaged by a pawl, h, whereby the'wheel and the link may be locked to hold the link back out of engaging position when required.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

. In a car-coupler, the draw-bar B, horizontally pivoted to the shank G, backed by the flat spring e, secured horizontally to said drawbar,and the inward rear-extension grip-piece,c, Y

in combination with the eye D, connected by chain to square shaft E,'having ratchet adapted to engage with pawl h onplatformv of car, all arrangedand operated substantially as shown and specified.

y In testimony whereof I affi'x my signaturein;

presence of two witnesses. V
