THOMAS SMITH, OF LONDON, ONTARIO, CANADA, ASSIGNOR OF TWO-THIRDS TO WILLIAM D. EDY AND JAMES N. EDY, BOTH OF SAME PLACE.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 317,232, dated May 5, 1885.
Application filed November 28, 1884.
To all whom it may concern:
Be it known that I, THOMAS SMITH, a subject of the Queen of Great Britain, and a resident of the city of London, in the county of Middlesex, in the Province of Ontario, in the Dominion of Canada, mechanic, have invented certain new and useful Improvements in Automatic Oar-Couplings, of which the following is a specification.
This invention relates to a device for automatically coupling cars together, and is especially adapted for railroad-cars My improvement consists in certain details of construction hereinafter described, and pointed out in the claims, reference being had to the accompanying drawings, wherein- Figure 1 is a side elevation of the draw-bars of two cars embodying my invention. Fig. 2 is a plan view of same. Fig. 3 is an edge View of the clevis, showing a square socket at the open end; and Fig. 4 is a side view of same. Fig. 5 is a plan view of the bolt which secures the clevis to the draw-bar, showing the square sections, which fit into the square sockets in the clevis, so that the clevis revolves with it, and the round sections, which revolve perfectly free in the draw-bar.
A A designate clevises attached to drawbars B B by bolts 0 C, passing through the clevis A near the ends as 'well as through the draw-bar B. This bolt 0 has square cross sections a n, which are formed on said bolt, so as to come opposite the square sockets s s in the open ends of the clevis, so that as the bolt 0 is revolved by the lever E, connected to the bolt by chain D, the clevis A is raised or lowered, according to the direction the leverE is operated.
F is a hook integral with each draw-bar B, with which hook the clevis A engages to couple the cars together.
I is a boss or elevated portion formed on the upper side of the draw-bar B, in which the bolt 0 is secured, and on which bolt 0 of the clevis A is pivoted, so that when the cars are coupled the clevis will be on the same plane (No model.)
and parallel with the draw-bars, so that the draft will be endwise of the draw-bars.
G is a pivotal arm, which is adjusted over the draw-bar B opposite the hook F by rods m m, to prevent the link becoming detached from the hook F on the draw-bar B by the jerking or jar of the cars when traveling, which arm G is moved to one side by the rods m m before uncoupling.
H is a jam-block projecting out from the car in a line with one arm of the clevis A, so that when the draw-bars strike together to couple, the spring which eases the jar of the draw-bars permits them to pass a short dis tance under the cars, when the end of the jam-block H engages with one side of the clevis A and instantly moves the curved end of the clevis over the hook F, which instantly couples the cars together.
The operation is as follows: The draw-bars B B will strike together and part again without coupling, when both clevisesare depended from the draw-bars, as shown at A in Fig. 1 of annexed drawings. The cars will strike to gether and instantly couple when either of the clevises is in the position shown by dotted line A in' Fig. 1 of annexed drawings.
Having thus described my invention, I claim l. The combination of the pivoted arm G, having rods m m for adjusting it, with the draw-bar, having a hook forming a link-cavity beneath the arm, as set forth.
2. The combination of the draw-bar B, le- 8') ver E, chain D, clevis A, having angular sockets s s, and bolt 0, having angular portions n n, to fitthe sockets, the lever being connected to the clevis-bolt by the chain, as set forth.
In testimony whereof I affix my signature in the presence of the two undersigned witnesses.
THOMAS SMITH.
