UNITED STATES PATENT OEEICE.
WILLIAM S. SAMPSON, OF BROOKLYN, NEW YORK.
DRAW-BAR FOR RAI LWAY-CARS.
SPECIFICATION forming part of Letters Patent No. 245,747, dated August 16, 1881.
Application led J une 6, 1881.
To all whom it may concern Be it known that I, WM. S. SAMPsoN, of the city ot' Brooklyn, county of Kings, `State of New York, have invented certain new and useful Improvements in Draw-Bars for (Jars, of' which the following is a specification.
My invention relates to improvements in railroad draw-bars, wherein the inward extension of the mouth-piece forms an additional support for the pi n, in conjunction with a system of abutments sustaining the front of the bar; also, in conjunction with the head of the bar, side openings for the safe elevation or depression of the link for the purpose of coupling; also, in conjunction with the head, a winged stem running from the 'rear of the head to the end of the bar, and, in conjunction with the Winged stem, a wearing surface or plate running out a short distance from the head toward the heel of the bar.
The purpose of my improvements is, first, to prevent the bending and breaking ofpins by the mouth-extension 5 second,to give great strength to the head of the bar by the system of abutments; third, to be safe from crushing or maiming the hand by handling the link through the side openings; fourth, to strengthen the stem of a bar by giving it a form wherein the metal is concentrated, and, ifth, to be able to chill the wearing-surface of'the bar without aii'ecting other parts of the casting. I accomplish these ends by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 represents a longitudinal vertical section of my drawbar5 Fig. 2, a cross-section at or, b of Fig. l; Fig. 3, a cross-section of Fig. l at o d. Fig. 4 represents the external side view, and Fig. 5 the external top View, of my bar.
Similar letters referto similar parts through the severa-l views.
In Fig. 1 the mouth-piece D extends inward to a line at a a, this line being where the pin enters and traverses the head through the two (No model.)
abutments G G, which lead from the front to the rear of the head-the whole system of abutments better seen in cross-section of Fig. 2.
In Figs. l, 3, 4, and 5 the wings of this bar are seen at W. In Figs. l and 3 the wearingsurface of the wings is seen at M.
In Figs. l and 4 the pin is seen at F, and the link at E, also an opening through the rear of the head and continuing along the wings a short distance at O.
In Figs. 1 and 4 the front face of the bar is seen at B. In Figs. l, 4, and 5 fillets of metal joining the bead and wings are seen at L, and in Fig.4 the side openings in the head of the bar are seen at H.
It is obvious that the express meaning of these changes in the make of a draw-bar have each a distinct value, and, alone or combined, aim to increase the eftieieney ot' this class ot' mechanism.
Having thus fully described my invention, what I desire to claim and secure by Letters Patent is- 1. In a draw-bar for cars, the inwardly-extended mouth-opening, in combination with the head B and abntments Gr, all for the purpose and substantiall y as herein set forth and described.
2. In a draw-bar, the abntments G, substan tially as herein described.
3. In a draw-bar of cast or malleable metal, the winged stem, for the purpose and substantially as herein described.
4. In a draw-bar of cast or malleable metal, a wearingsurface, M, spanning from wing to wing of the lower side of the stem of a wingshaped draw-bar, substantially as herein shown and described.
WM. S. SAMPSON. Witnesses:
