NITED STATES IVARREN DORR, OF GARDINER, MAINE.
CAR-COUPLING.
SPECIFICATION forming part of Letters Patent No. 405,953, dated June 25, 1889.
Application filed October 4, 1888. Serial No. 287,144. (No model.)
To aZZ whom, it may concern;
Be it known that I, IVARREN DORR, a citizen of the United States of America, residing at Gardiner, in the county of Kennebec and State of Maine, have invented certain new and useful Improvements in Oar-Couplers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
My invention relates to certain new and useful improvements in car-couplers, the object of the same being to provide a coupler with means by which cars may be coupled automatically, and which will adapt itself to cars of different heights; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth, and specifically pointed out in the claims.
My invention also consists in the special construction of the pin-support, whereby the pin will fall and enter the perforations in the draw-heads to couple them.
In the accompanyingdrawings, Figure 1 is a perspective view of a car-coupler constructed in accordance with my invention, showing the pin supported upon the draw-head. Fig. 2 is a sectional view showing the pin supported in a position for coupling in full lines and a draw-head and pin coupled in dotted lines.
In the accompanying drawings, A refers to the draw-head connected to the car-body at its front end by a depending plate a, secured to the transverse beam A of the car, this plate a having an enlarged opening, through which the draw-head passes to allowsaid draw-head to raise and lower. The plate a is bent rearwardly beneath the draw-head and secured to side beams attached underneath thecar. The rear end of the draw-head is provided with a spring and is held within its frame by a transverse pin.
The front end of the draw-head is provided with three integral plates 1), Z), and I), which form corresponding horizontal slots. The
front ends of the plates and the rear walls of the slots are rounded, the two lower plates b" and I) having vertical perforations c and 0', while the upper plate I) has formed therein a circular open-ended slot 0, of greater diameter than the perforations c c beneath the same. This open-ended circular slot 0 is slightly beveled. Rear of this slot and connecting therewith a semicircular recess d is formed in the upper surface of the draw-head, in which the end of the coupling-pin is adapted to lie.
Above the coupling end of the draw-head is secured a pin-guide D, formed with a central enlarged portion having a vertical inclined groove, within which the pin rests, the head thereof being located above the guide, while the lower ends bear in the recess d. Extending on each side of the enlarged portion of the guide are wings e c, by means of which it is secured to the ear-body.
IVhen it is desired to couple the cars to each other, the pin is withdrawn and placed so that its end will rest in the recess (Z, the body of the pin inclining toward the car and rest-ing within the inclined groove or recess of the pin-guide. Vhen the cars come together, the projecting plates will lock, and the jar occasioned thereby will throw the pin out of the groove, so that it will slide into the circular op en-ended slot and pass through the perfora tions and couple the draw-heads.
Cars of different heights may be coupled without the necessity of manually adjusting the draw-heads, and by providing the proj ecting plate I) of the draw-head with the openended slot, as hereinbefore described, cars will be coupled automatically when the drawhead supporting the pin is lower than the opposite draw-head, as the end of the pin will pass through the open end of the slot.
The coupling hereinbefore described is simple, per iits the use of an ordinary couplingpin, and has no movable parts liable to get out of order or become detached, and the recesses and projecting plates of the draw-head being rounded permits the cars swinging upon the coupling-pin in rounding curves.
I am aware that prior to my invention it has been proposed to provide the draw-heads of cars with a series of horizontal slots with corresponding projecting plates, said projecting plates having perforations through which a coupling-pin passes, and I do not claim this feature, broadly; but
What I claim as new, and desire to secure by Letters Patent, is-
1. In a car-coupler, a draw-head A, having a series of projecting plates with rounded ends, the upper projecting plate having an open-ended circular slot, the opening in said slot being of sufficient size to permit the coupling-pin to pass through the same, substantially as shown, and for the purpose set forth.
2. In a car-coupler, the combination of a draw-head A, having outwardly-projecting plates 1), b, and b perforations c 0 formed 'therein, the upper plate having an openended slot 0, a recess cl in the rear of said slot, and a pin-guide D, having an inclined groove within which the pin rests, the upper WARREN DORR.
