CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 456,987, dated August 4, I891.

Application filed November 14, 1890. Serial No. 371,483. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALBERT FONTAYNE, S12, a citizen of the United States, residing at'Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare the following to be a full, clear, and'exact description of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

The present inventionrelates more especially to thatclass of vertical-axis automatic couplers in which a pair of counterpart hookshaped bars or links are interlocked to effect a coupling.

The object of the present improvement is in the main to provide a simple, durable, and effective coupler embodying the following fea- A tures: first, a perfect and automatic coupling on any line and under any and all ordinary conditions; second, a" tendency of the twin coupling-bars to adhere together with increased rigidity with an increase of the strain,'so as to virtually constitute a single link between the pivot-pins and so permit of great freedom of movement of the draw-heads in a similar manner to the well-known pin and-link coupler in general use; third, the avoidance of any setting of parts by hand, and a coupling under all circumstances without any supervision whatever; fourth, an improved link attachment aifording means for a coupling with any vertical-pin draw-head couplera feature common to all approved types of car-couplings. I attain such object by the construction and arrangement of parts illustrated in the accompanying drawings, in which Figure 1 is an inverted plan view of a pair of draw-heads in coupled condition with my invention applied thereto; Fig. 2, a horizontal section; Fig. 3, a side elevation of the same, and Fig. 4 a horizontal section showing the arrangement of my improved coupling parts whenemployed in making a connection with any'other type of vertical-pin couplers met with in use.

Similar numerals of reference indicate like parts in the several views. 7

Referring to the drawings, 1 1 represent a pair of draw-heads and their attached drawbars, of any usual or approved construction, the front or head portion proper being of a forked construction to form jaws or bufferheads 2 2, between which the counterpart hook-shaped coupling bars or links 3 3 of the present invention are pivoted by vertically-arranged pivot-pins at 4, the upper ends of which are of a cranked formation, so as to furnish means for operating the'hooks in the uncoupling operation, and such'uncoupling may be effected from either side of the car or from the top, by a suitable rod or lever attached to the crank-armsof the piv0t'-pins,or by a chain and pulley, as is usual to many forms of car-couplings heretofore proposed.

The hook-shaped coupling-bars 3 3 are of a twin or counterpart construct-ion and are pivoted in longitudinal line in their respective heads 1 1, each consisting of astraight shank or body portion 5, having at one end a pivoteye 6 and an outwardly or laterally projecting heel 7 and at the other end a hookshaped laterally-arranged projection 8, the forwardly-projecting point of which has its inner vertical face beveled or rounded, as shown, so that in the act of coupling such counterpart faces will ride one against the other; In the present invention the hook-shaped coupling-bars 3 3 project outv past their respective draw-heads in proper position for coupling, and in the act of coupling they'will ride against each other until their respective hook ends move past the pivot ends of the bars to overlap and engage back of said ends and the laterally-arranged heels 7 on the same to perfect the coupling. In such coupled condition the greater the amount of strain upon the couplingparts the greater will be the tendency of the counterpart-bars 3 3 to adhere together with increased rigidity along their whole contiguous surfaces, so as to constitute to all intents and purposes a single couplingbar between the pivot-pins. In consequence the tendency in active use will be to impose both the strain and pivotal movement Wholly upon or around the pivot-pins of the coupling-bars and in so doing admit of the great freedom of the draw-heads to movement in all directions inherent to the ordinary pinand-link coupler now in general use, such movement of the draw-head being rendered necessary by the ordinary oscillation ofthe cars in their travel.

The bevel or inclination of the contact-faces of the laterally-projecting hooks 8 and heels 7 of the respective coupling-bars is of such a forward pitch or rake as to necessitate a slight drawing together of the draw-heads in the uncoupling operation. The laterally-projecting heel 7 of the coupling-bar that is being manipulated in the act of uncoupling acts as a lever against the contact-face of the hook 8 of the other coupling-bar to pull the drawheads together until the heel 7 assumes such angle by which the said hook can slip away with freedom to complete the act of separation. This feature of construction affords ample and efficient means to prevent accidental uncoupling of the parts in use, and in practice the aforesaid bevel, rake, or inclination of the contact-faces may be varied, as the judgment of the constructor or the requirements of the-particular use may suggest.

The hook-shapedcoupling-bars 3 3 are held in a yielding manner in proper couplingposition, as well as in their subsequent coupled condition, by means of springs 9 9, which in the present invention are of a straight bar or rod formation attached to downwardly-projecting lugs on the draw-bars, as shown, with their free ends engaging the hook-shaped coupling-bars 3 3 in either of p the following ways: first, by engaging a downwardly-projecting stud 10 on the coupling-bar that has limited movement in a recess 11 in the edges of the draw-head, as illustrated to the right in Fig. 1; second, by engaging against a crankarm 12 on the lower end of the pivot-pin 4 of the hook-shaped coupling-bar, as illustrated to the left in Fig. 1. The latter construction is preferred when the feature of a link attachment is used in connection with my aforesaid coupling construction in the following manner: 13 is an eye formed at the outer end of thelaterally-projecting heel 7 of the coupling-bar 3, and leis an ordinary couplinglink arranged in said eye, the purpose of this provision being to enable a car having my improved coupler applied to couple with a car having any approved form of couplers provided with the ordinary vertical couplingpin. For such use the hook-shaped coupling-bar 3 will be swung around, as indicated in Fig. 4, to bring the ordinary link 14 into active coupling position. 15 is a vertical stop-pin passing through the draw-head and acting as a stop for the coupling-bar 3' in either of its above-described positions.

Having thus fully described my said invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an automatic car-coupling, the combination, with suitable draw-head's or bases,

' of a pair of pivoted twin coupling bars having pivot-eyes, laterally-extendingheels, and" hook-shaped free ends that are adapted to overlap and engage back of the respective pivot ends and lateral heels of the couplingbars, substantially as set forth.

2. In an automatic car-coupling, the combination, with suitable draw-heads or bases, of a pair of pivoted twin coupling-bars having pivot-eyes, laterally-extending heels, and

hook-shaped free ends that are adapted to .overlap and engage back of the respective pivot ends and lateral heels of the couplingbars, the contact-faces of the hooks and'heels being pitched or raked forward, substantially as set forth.

3. In a vertical-axis car-coupling essentially as herein described, the combination of the coupling-bar 3, having a laterally-projectingheel 7, provided with an eye 13', with the coupling-link 14 arranged therein, substam tially" as set forth.

In testimony whereof I affix my signature'in presence of two witnesses.

ALBERT FONTAYNE, SR.
