UNCOUPLING DEVICE FOR CAB-COUPLINGS.
Specification of Laue" Patent.
Patented Jan. 5, 1915.
191%. Serial No. 858,696.
Original application filed April 29, 1911, Serial No. 624,178. Divided and tliis application filed August 28,
.invented certain new and useful Improvements in Uncoupling Devices for Car-Couplers, of which the following is a specification.
This application is a division of my application filed April 29, 1911, Serial No.-
The primary object of my invention is the provision of an improved and positive form of flexible connection wherein the use of chains, loose links and similar devices is avoided; and with this and minor objects in view my invention consists of the parts and combination of parts as will be hereinafter pointed out.
In the drawings Figure 1 is a top plan view of a part of a car with my improved release rigging attached. Fig. 2 is a front elevation of the same.
The reference numeral 1 designates the car, 2 the draw bar or coupler head and 3 the locking pin thereof.
The pin lifting lever is composed of a relatively long arm 4 and a relatively short portion 4 having a vertically disposed depending portion 6, said portions being at right angles to each other; the inner end of the relatively long portion passes through the eye of the lock pin, and terminates in a laterally extending hook 5. The relatively short portion 4 is permanently secured to the end of the car by means of an eye bolt 7 which forms a loose pivotal connection between the said short arm and the car thereby accommodating the pin lifting lever to the swinging movement of the uncoupling muoperating lever.
The pin lifting lever is operated through the medium of the operating lever 8 pivotally mounted on the bracket 9 which in turn is secured to the end of the car, as shown, the outer portion of the lever being down wardly deflected to a plane below the under face of the car and provided with a foot or hand member 10 preferably extended rearwardly under the car. A portion of the lever 8 intermediate its pivot and inner end is deflected laterallv as at 11 while its extreme inner end portion is deflected forwardly as at 12 at right angles to the portion 8, the deflected portions 11 and 12 underlying the relatively long portion of the pin lifting lever, as shown in Fig. 1, the said relatively long portion having a floating bearing on said deflected portions 11 and 12 of the lever 8; so that the pin lifting lever may accommodate itself to the vertical swinging movement of the lever 8, which moves in the vertical plane of the end of the car.
The bracket 9 is provided with a laterally extending arm 13 having overhanging lugs 14 and 15, the lug 15 being set at an angle to the lug 14: whereby the space between these lugs is flaring.
16 is a cotter pin passing through the lugs lat and 15 and constitutes a guide for the operating lever 8.
I claim- 1. In an uncoupling device for car couplers, the combination with a pin lifting lever having a relatively long portion adapted to engage the pin of the coupler, and a relatively short portion terminating in an eye, said portions being at right angles to each other a device secured to the end of a car constructed to engage the eye of the said short portion whereby the pin lifting lever is connected directly to the car, of an operating lever pivotally mounted on the end of a car for vertical movement in the plane of the end of the car, the inner end of the operating lever underlying and having a floating bearing against said pin lifting lever.
2. In an uncoupling device for car couplers, the combination with a pin lifting lever haying a relatively long portion, and a relatively short portion terminating in an eye, said portions being at right angles to each other, an eye bolt secured to the end of the car to which the eye on the short portion of the pin lever is connected to form a flexible joint therebetween whereby the said pin is directly connected to the end of the car, of an operating lever 'pivotally mounted on the end of the car for vertical movement in the plane of the end of the car and constructed to engage and operate said pin lever.
3. In an uncoupling device for car couplers, the combination with a pin lifting lever having a relatively long portion, and
a relatively short portion terminating in an eye,- an eye bolt secured to the end of the car to which the eye on the short portion ofthe pin lever is connected to form a flexi- 5 ble joint therebetween whereby the said lever isdirectly connected to the end of the car, of an operating lever pivotally mounted on the end. of the car for vertical movement in the-plane of the end of the car and constructed to engage said pin lever,
. said operating rod having a laterally bent portion intermediate its pivot and its inner" end and an inner end portion bent at right
