DRAW-GEAR FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 290,241, dated December 18, 1883.

Auolication filed August 2,1883. (No model.) i

To all whom, it may concern Be it known that we, GEORGE J. JOHNSON and EUGENE H. THOMAS, residing at La Grosse,

in the county of- La Orosse and State of WViscousin, have invented a new and useful means of preventing the withdrawal of draw-bars for coupling trains together, of which the follow ing is a specification. Our invention relates to improvements in the means of preventing draw-bars connecting cars together from being pulled or drawn out; and it consists in the novel arrangement and combination of parts, as hereinafter described, and specifically set forth in the claim; We attain these objects by the mechanism illustrated in the accompanying drawing, in which- The figure is a plan view of our improvement.

Similar letters refer to similar parts.

In the drawing, A A represent the sills or draft-timbers of an ordinary car, and B the draw-bar formed at its front end, preferably The'bar B, at its nally, and is supported upon cross-pieces L, suitably secured to the sills A. 1

To each of the inner sides of the sills A are secured or made integral therewith inwardlyextending pieces or lugs I I I I, placed at sufficient distances apart, and connected together on both the top and bottom sides by means of longitudinal strips or plates I", which thus form, when connected, rectangular slots 7? on each of the inner sides of the sills and between the projections I I and I I.

To the rear end of the draw-bar B is secured a longitudinal rod or bolt, G screw-threaded at its end, the said bolt being adapted to pass through the cross-pieces H and a band or plate, E, and thus allow the bar B to have a longitudinal play by meansof the pieces H sliding both backward and forward in the slots t Between the cross-pieces H H and winding around the rod Gis a spiral spring, F, the purpose of which will be hereinafter more fully described.

To the rear end of the draw-bar B is secured,

nected to sills by cross-pieces, and having both on its upper and lower sides, a plate or cap piece, E, passing over and extending around the cross-pieces H.

In front of the plate E, and on each side of the rear portion of the bar B, are two tapering lugs, D, provided with seats 61, and which are made preferably in the manner here shown, 5 5

'and are cast either with the bar or secured thereto by any suitable means, as may be found I most desirable.

On the inner sides of the sills A, and in front of the lugs D, are formed with or secured therevto lugs 0, made almost similar in shape to the lugs D, but facing in opposite directions, thereby adapting the lugs D and C to engage with 7 each other in case of the bar B being drawn or pulled out to a sufficient distance. It willthus be seen that, even should, the nut on the rod Gr or. the spring F become worn or by accident broken, the barB would still be held in its po sition by means of the lugs becoming engaged with each other, and which would thus prevent accidents.

In connecting or coupling cars together, to prevent the bar B from being pushed backward too far, small inclinedlugs K are formed on the lugs I I, which are adapted to engage or come in contact with the inclined portion of the lugs D. We have here shown the longitudinal pieces I I and lugs O O as being in separate pieces but we may, should it be found preferable, cast or mold them in one continuous piece, which would in some cases be found more advantageous and tend bothto save time and trouble.

The several parts here enumerated may be made of any materialfoundsuitable-such, for instance, as steel, brass, wrought or cast iron, and the like. 4,

By our invention all danger of the draw-bar becoming disconnected from its position is averted, thereby preventing accidents from 0 'such causes, as is now generally the case, and

which we consider as an important feature, and one of great necessity. We are aware that draw-bars have. been consprings for preventing'shock, and we therelugs D D, all substantially as described and for the purposes set forth.

Dated at La Orosse, \Visconsin, this 6th day of Jane, A. D. 1883.
