SPECIFICATION forming part of Letters Patent YNo. 532,337, dated January 8, 1895.

Application filed March 28, 1894. Serial No. 505,467. (No model.)

T0 ctZZ whom t may concern:

4Be it known that I, HENRY RIENOW, a citi-` zen ot' the United States, anda resident of Prairie du Chien, in the county ofCrawford and State of Wisconsin, have invented certain new and useful Improvements in CarCoup-` which also the cars may be uncoupled without the necessity of the brakeman going between the cars. f

Among some of the objects of the invention are improved means for adjusting the coupling link so as to couple cars of different heights, to provide means for holding the coupling pi'ns in an elevated position so as to couple automatically and means also for uncoupling the cars without the necessity of. the operator going between the same. There are also other objects and advantages which will be apparent to those skilled in the art to which the invention pertains. y

The invention-consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a central longitudinal section of a car coupling constructed in accordance with my invention. Fig. 2 is a plan view of the same.

Figs. 3 and 4 are detail perspective'views.

Fig. 5 is a detail sectional view.

In the said drawings the reference numeral 1 designates the draw-bar which may be of any ordinary or suitable construction, adapted to be secured to the bottom of a car, and provided with the usual flaring mouth 2. On the lower inner side of the draw-bar near the h mouth thereof is a raised beveled projection 3, upon which the inner end of the coupling link 4, rests. The upper side of the draw-bar is formed with a central longitudinal slot, and is provided with an extension consisting of the walls 6 at each side of the said slot, a

l top 7, and a rear wall 8, all of which are preterably formed integral with the draw-bar.

` The numerals 9 and 10, designate aligned apertures in the top of the extension and bottom of the draw-bar respectively, to receive the coupling pin 12'. This pin is provided with a head 13, underneath of which engages the bifnrcated end 14, of an arm 15, pivoted to brackets 16, formed on the rear end of the extension ot the draw-bar. Secured to the upper side of the arm is a lug17, with which is connected one end of a chain 18, the other end of which is secured to a sleeve 19 on a transverse shaft 20, journaled in bearings2l on the upper end of a vertical plate or block 23, secu red to the car and generally called the deadwood. It is obvious, however, that this shaft may be journaled to the side, front or top of the car, if desired, and its end is bent 24. Fixed to the said shaft is adisk 25, having formed on its periphery ratchet teeth 26, with which is adapted to engage a hooked pawl 27,pivoted to a vertical arm 28 secured to the outside of the car. Also secured to the outer side of the car is a spring catchf29, with which the leve/r engages. y

Located within the draw-bar is a swinging stop block 30, formed with a slot 31, through which passes a pin 32, which also passes through apertures in the side walls 6, by which said block is pivotally connected with the extension,the said slot allowing the block to have sutcient play to prevent injury. The upper front end of `this block is cut away at a right angle forming an operating lever forming va shoulder 34, upon which the lower matically, the lever 24 is thrown up, elevating the coupling pin 12. -The lever 39 is then thrown up and back, allowing the stop block 30 to swing forward so that the shoulder 34, will engage under the lower end of the pin and hold it in its raised position. The lever The operation is as follows: To couple autol [OO Y 24, is then turned backward so that the bifurcated end of the arm 15, will be disengaged from the head of the coupling pin as seen in full line in Fig. 5. As the link from an approaching car enters the mouth of the drawbar it will strike the stop block forcing itbackward, disengaging the shoulder thereof from the .pin and allowing the latter to drop and pass through the link into the aperture in the bottom of the draw-bar. pin can be elevated by hand or it can be raised by means of the lever 24, thus bviating the necessity of the operator going between lthe cars. in the ordinary manner if desired.

The link can be adjusted so as to couple lcars of unequal heights, by simply pushing in the link more orless according as the other end of the link is to be raised or lowered. If the car to be coupled is higher than the one carrying the link the latter is pushed inward so that its inner end will engage with the curved front of the stop block, and swing the latter backward. The curved project-ion 3v serves as a fulcrum for the link land owing lto the curvature of the block the inner end of the link will be gradually depressed the farther it is pushed in and the front or outer end be correspondingly elevated. n See Fig. 2.

Having thus fully described my invention, what I claim is l. In a car coupling, the combination with the draw-bar having the flaring mouth, and

formed with an aperture for the passage of the coupling pin, the extension having analigned aperture, the headed coupling pin,

To uncouple, the

The car can also be coupled by hand the bifurcated pivoted` arm,.the chain connected therewith, the transverse shaft to which said chain is connected, having an operating lever and a/disk provided with ratchet teeth, and the pivoted hooked pawl, of the blocks located in said draw-bar having an elongated slot, and formed with a shoulder for engaging with the coupling pin, the pin passing through said slot, the chain connected therewith and the Vshaft to which said chain is secured; substantially as described.

2. In a car coupling, thecombination with the draw-barV having the flaring mouth, a curved projection vformed with an aperture, the extension formed with an 'aligned aperture, the headed coupling pin, the bifurcated pivoted arm, the chain `connected therewith, t-he transverse shaft to which said chain is connected having an operating lever and a disk yprovided with ratchet teeth, and the hooked pivoted lpawl, of the stop block located in said draw-bar having an elongated slot, a shoulder for engaging with the lower end of the coupling pin, and having its front side curved from the said shoulder to its lower end, the pin passing through said slot, the shaft having an operating lever and the chain connecting said shaft and stop block; substantially as described.

In testimony that I claim the foregoing as my own I have hereunto aiiixed my signature in presence of two witnesses.
