CONRAD KNZLER, or TOLEDO, Omo.

CAR-COUPLING.

SPECIFICATION formingpart of Letters Patent No. 407,020; dated July 16, 1889.

Application tiled March 27, 1889. Serial No. 304,999. (No model.)

To all wiz/0m, it may concern:

Be it known that I, CONRAD KNZLER, a citizen of Switzerland, who has declared his intention to become a citizen of the United States, nowaresidcnt of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Car- Couplers; and I do hereby declare that the fo1- lowing is a full, clear, and exact description of the invention, which 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 the letters of reference marked thereon, which form part of this specification.

My invention relates to car-couplings, and has for its Object to provide a coupling that shall be automatic in action, easy to uncouple, and adapted to the'use of the ordinary link and pin when necessary.

In the drawings, Figure l is a perspective view of one end ot a box or freight car with my coupling applied thereto. Fig. 2 is a plan view of the Opposite sections of the coupling in engagement. Fig. 3 is a side view of the same. Fig. 4 is a plan view showing one of the sections coupled with the Ordinary drawbar by means of a link and pin. Fig. 5 is a detail view of one of the sliding wedges for uncoupling the sections.

To the draw-bar A is pivotally secu red two side plates B, to which are secured an upper and a lower coupling-bar C and C, respectively, said bars being' pivotally secured to the side plates B by means of bolts D. The forward ends of the coupling-bars C are spearshaped or double-barbed, the incline of the same extending rearwardly, of a width relative tothe width of the bar, to form shoulders D'. Directly in rear of the shoulder D is an eye E, of a diameter to receive a coupling-pin, and from the eye is extended rearwardly a slot F, adapted to receive movable portions OE the device for uncoupling the sections, as will be more fully described.

G designates a plate formed of a thickness and length to move within slot F, and be confined therein when the coupling-bars are separated the full extent necessary. Plate G is formed with a central extension Il, to which is attached a lever I in any preferred manner,

cured to the draw-bar.

K K designate upper and lower sections, respectively, of uncoupling-wedges, formed with a body portion L, adapted to slide within slot F, and ot' a width to extend through the same upon each side of the couplingbar a sufficient distance to allow strips M, having inclined ends h' to be secured to the body portion L upon each side thereof above and below the coupling-bar. The inner strips M are of greater length than the outer strips, thereby allowing a portion of each to extend to the rear side' of the plate G and embrace the same, and when the inner end of the body portion L nearly abuts against plate G to allow a pin or bolt N to be passed through perforations in the ends of the strips at the rear side of said plate, whereby each section is pivotally connected with the plate and move forward or rearward as theA plate is actuated by lever I.

K are leaf-springs, attached at one end to the draw-bar, with the free end bearing upon the coupling-bar C, thereby preventing all rattle or jar of the coupling-bars.

In operatioinwhen two cars are to be coupled, as the coupling-bars C and C meet, the inclined portions of one section pass between and the same of the Opposite section until bump ers meet, at which time the shoulders D are in engagement and the cars are coupled.

In order to uncouple the sections, the free .end of lever I of either section is grasped and moved toward the car, thereby moving plate G in slot F toward the arrow-heads, causing the inclined faces M of the outer ends of strips M to pass between the incline of the arrow-head and raise the shoulder of the same from engagement with the shoulder of the arrow-head of the Opposite coupling-bar, and the sections are uncoupled.

Then it is desired to use a link 'and pin, plate G and the sections K K are moved back out of the lino with eye E, and the link, as shown in Fig. 4l, and the sections are coupled.

In Fig. 'l is shown in dotted lines an attachment by which the sections may be un coupled from the car. In this construction there is an arm J", extending at right angles from the leverJ and integral therewith,theresaid lever being fulcrumed in an arm J, se-

IOO

by forming a bell-crank lever fulcrumed at J, one end of the leverbeing attached to the plate G at I'I, and the free end J having a perforation into which is passed the lower end of a lever P, (shown in dotted 1ines,) the lever P being fulcrumed at P upon the base of the car, and the upper end extended to any desired height-as, for instance, when attached to a box-car it may extend to or near the top, or in passenger-cars to a convenient height to be out of the way of the railing upon the platform-and, if desired, the free end of the lever J may be omitted, thereby forming solely a bell-crank lever, the operation and mechanism being the same for uncoupling the sections. It Will be seen that the device is inexpensive of construction, positive in action, easily uncoupled, and adapted to the use of the link and pin.

What I claim is-- l. In a car-coupler, a draw-bar, plates pivloted upon the same, and duplex co upling-bars having pointed ends and engaging-shoulders pivotally connected to the plates, in combination with movable plates having wedge-shaped ends adapted to uncouple the coupling-bars when in engagement, as and for the purpose set forth.

2. In a car-coupler, two coupling -bars formed with inclined ends -and engagingshoulders, each bar having an elongated opening in the body portion thereof, in combination with a plate extending within each opening and connected to a lever and to movable plates Within the slots in the coupling-bars, each of the latter having wedge-shaped ends, as and for the purpose set forth.

8. In a car-coupling, two coupling-bars formed with inclined ends and engagingshou1ders,in combination with a lever connected with amovable series of inclined strips adapted to pass between the inclines of the engaging-bars,with which they are connected, as and for the purpose set Jforth.

In testimony that I claim the foregoing as my own I hereby aiiix my signature in presence of two witnesses.

y CONRAD KNZLER.
