Cisco, Highland, Ind., assignor to Stanray Corporation, Chicago, 111., a corporation of Delaware Filed Dec. 10, 1962, Ser. No. 243,977 Claims. (Cl. 213-166) This invention relates to railway car coupler operating mechanisms. More specifically the invention relates to a particular type of operating lever for operating the coupler upon rotation of the lever in a counter-clockwise direction, and to a bracket for rotatably supporting the outer end of the operating lever for convenient manipulation by a trainman from the side of the car.
This application is a continuation-in-part of my copending application Serial No. 65,692 filed October 28, 1960, now abandoned.
Due to loss and damage to lading carried by railroads, which loss has been steadily increasing, ways and means of reducing the same have been studied. A good deal of the damage comes from shocks to the car, and accordingly there has been developed a sliding center sill underframe with a cushioning arrangement for railway cars I which would have little or no recoil and which would alment have been made to move forward and backward a f greater and greater distance. Whereas they would move in the ordinary draft gear arrangement some five to six inches, with the sliding center sill types the couplers have been made to move forty inches and more. This meant greater side swing of the couplers when the cars are rounding curves; There is a great tendency to build longer cars'resulting in greater overhang from truck. centers to couplers and therefore greaterside travel is requied at the coupler to negotiate railroad curves.
Specifically, the invention relates to an operating lever for a bottom operating coupler, mounted in an underframe construction having a very wide side swing and/ or a cushion underframe resulting in excessive relative longitudinal movement between car body and coupler. Therefore the rod and' the support must be designed to accommodate this wide side swing and long travel between car body and coupler, this being the principal object of the invention.
A further object of the present invention is to provide an operating device which will contract to about (thirtyeightin'ches when the coupler is in extreme buff position andextend to some six feet and more to accommodate couplers installed in these newer types of sliding center sills with cushioning arrangement therein, and side swing. e i
Another object is to construct such an operating device at a minimum of expense and yet be very efiicient in op I oration.
Other objects and advantages of the invention appear in the following description thereof.

The prior art discloses coupler operating devices for use with A.A.R. type E and earlier couplers, which devices are constructed of a plurality of parts for translating rotary motion from one part to the other and to the coupler rotor for operating the coupler. But in each instance it can be demonstrably proven that such devices are not operable when used with the recently developed sliding center sill with cushioned underframe having couplers with shanks varying in length from 21 to 34% and wherein the couplers themselves move outwardly from extreme buff position to approximately 46", and
may swing laterally up to 15 on either side of the lonfactors which must be considered in a given design are type of coupler, side travel of coupler, striker projection and construction, and Width of car.
Referring now to the modification shown in FIGURES l to 6 inclusive, 10 indicates the end of a car to which the device is applied, and 12 indicates the striker to which the car coupler is assembled and which is attached to the center sill of the car. Since the coupler operating rod or lever is pivotally attached at one end to the lock lifter of the coupler for rotating and lifting the lock lifter to unlock the coupler, and at the other'end is mounted in a bracket secured to the end of the car, it is obvious that the bracket andouter end of the rod or lever must be con structed so as to compensate for the wide swing and/ or long travel of couplers mounted in cushion underfraines.
The operating rod or lever is formed in 'two parts, the inner part 14, and the outer part 16. The bracket for mounting the outer part of the lever to the car is, shown generally at 18. This bracket comprises an angle member. having a vertical flange 20, which. is riveted or otherwise secured to the end of the car. The other flange 22 is horizontally disposed, projecting outwardly normally, and the outer, edge of which is inclined, diverging from the car end toward the coupler, as shown. The bracket is of substantial length so as to accommodate movement of the lever portion 14 in following the sidewise and particular ly'the lengthwise relative movement of coupler'to car:
body. a At either outer corner of the horizontal flange 22 is a reverse J-shaped member, each having a top horizontal flange 24 which rests 'flatwise against and is'securedto the flange 22. 'At'the outer end offla'nge 24 the members are turned downwardly providing a vertical flange 26. which terminate in upwardly .facing U -bendsf28 providing bearings for rotatably-reoeiving the outer part 16 of the operating lever.
from the car end toward the coupler;
In FIGURES and 6 a modified'form of bracket is shown, the angle comprising the flanges 2t and' 22being' thesame. However, the'members ateachcorner of the horizontal flange 22 in this modification are different in that the hanger part of the bracket comprises a strap likeangleimernber having ahorizontal flange 30 and a; V
vertical-flange 32 depending from the horizontal flange.
It will be'noted i'n FIGURE 1 that the bearings are mounted on a common axis which diverges The eye is rather loose around the bars 42 and 44 so as to, permit considerable angling of the eye as well as sliding of the eye, on the bars. Obviously when the handle 40 is rotated,,the rodthatis in the bearings will be the axis of rotation and the other will act as a lever arm car is very simple. The hook-50 is applied'to the lock To the vertical flange is secured in any desired manner a Z-shapedstrap member 34, one flangeofeach of which rests flatwise against and is secured to the flange 32. The
other flange 36 of the Z-shaped member is ma parallel spaced vertioalplane with flange 34, and. the web '38 therebetween connects the two forming'upwardly facing 1ifter,="theeye 56 slid on thehairpin portion and .the hair-. pin portionapplied to the'bearings. When therein, the parts cannot separate. .l'
It isperfectlyobvious that the eye 56 need .not be elongated so as to surround both rods .42 and 44'. ''It may be a simple eyesur'rounding'rod 42 only with the depending portion in front of rod 44, and function equally as well. Referring now to' the modification shown in FIGURES .7-.10 ofthe d'rawings,'=and more particularly to FIGURE '7, the-uncoupling assembly isindicated generally by reference numera1'60 and includes abracket 62 and azlever hearings to rotatably receive the operating rod. In either modification of bearings, they mu'st be spaced about "34".
apart so that the operating rod may extend tethe required] a '30 The outer 'end 16 of the operating rod comprises a de-1. pending handle portion '40, and a hairpin shaped portion six feet;
consisting of two spaced. parallel horizontally'disposed portions 42 and 44 connected by a U-bend 46; The free end terminates at the handle'portion to which it is secured by welding or the like. Either horizontal portion 42 or} 44 may rest in the bearingportion 28 of the brackefl but 5 in the modification shown in FIGS. land 3 it is the lower;
portion 44 that isto be positioned in the bearings 28;-
One reason for this is'that the rotation "of :the rod. is
counterclockwise when viewed from the handle end; and means must be provided to prevent. clockwise rotation: of therod. Thus in the bracket shown in FIG; 3, the" handle is'free to. be rotated counterclockwise, .but the portion 42 of the rod would bump against flange 26 if it were attempted to rotate. the handle'in a clockwise" assembly having a'firstor handle section 64.and a second coupler actuating section 68 which is non-rotatingly slid able with respect to the section 64 and terminates in a hook 7 tl' for a purpose hereafter-apparent. This slidabil- I ityis necessary to'compen'satefor' the wide swing and longrelativeitravel of the coupler, shown at 72, with respect to the car body, indicated at 74." Inall modifica tions the'distance' the lever extendsis determined by the angular-ity of mounting'of the device in its bracket, the amount of travel of the sliding center sill and its cushionving arrangement, the length of the coupler shank, the de- 7 gree of lateral swing offthe coupler and the size ofthe striker opening. a g
The bracket 62"comprises az-shaped 'member'which includes a flat substantially rectangular section 76, which is securedzto and extends downwardly with respect tofthe end ofthecarbody 74,"a.;section 80substantially perpendirection. It will be noted that if the rod were positioned could be rotated without restraint: in either direction;
The purpose-of making the bottom member 44 of the unit shown inFIGURES 1-3 the center of-rotation thereof is so thatthe massof the lever material above and below with the upper-portion 42 in thebearings 2 8,'the'handle the center of rotation'is approximately equal; Therefore whenbutf ordraft shock loads occurofsuflicientmag'nitude to lcause rotation of the lever and possible lockset 1' I of coupler, thebalancing ioflthe mas's' above andb'elow" the,center of rotation will removethe tendencyof the lever to. rotate under such shock conditions; 1

The handle section is then turned laterally inwardly a substantial distance as shown at 66.
The lever section 68 comprises an elongated straight portion 100 terminating at its inner end in the hook 70 for attachment to the car coupler indicated at 72. The outer end of this rod portion 100 is bent back upon itself by a U-bend indicated at 104 forming a shorter portion 102 in spaced parallel relation to portion 100 and the end of which is bent at right angles thereto as at 106 into abutment with portion 100. The lever section 68 may be made in two pieces by providing a welded joint in the vicinity of the U-bend 104.
The lever section 68 is mounted for sliding movement with respect to the handle section 64 by means of a pair of spaced upwardly facing U-shaped clips 108108. Clips 108 have parallel arms 110 and 112, which arms surround the portions 100 and 102 of the inner coupler operating section 68 and the free ends of the arms 110 and 112 are welded to the opposite sides of portion 66 of the handle section 64. Arms 1153 and 112 are provided with registering openings through which bolts 114 extend between the lever sections 109 and 102. On these bolts, between arms 110 and 112 are anti-friction sleeves 116 upon which are mounted rollers 118 which roll between the members 100 and 102 and maintain the handle section 64 out of frictional contact with coupler operating section 63. The coupler operating section 68 is thus free to slidingly and non-rotatingly move relative to the handle section 64 and thus compensate for in-and-out and lateral movements of the coupler.
From the foregoing teaching those versed in this art will understand how the operating device functions. When it is desired to unlock the coupler, for example, the handle 40 or 99 is grasped by a trainman and pulled outwardly from the car so as to pivotally rotate in a counterclockwise direction with respect to its clevis 81 or 8 This rotation will cause the sections 64 and 68 to likewise move in an orbital path counterclockwise to thus rotate the rotor of the coupler.
There has thus been provided a coupler operating device assembly which accommodates couplers mounted in sliding center sills with cushion underframes, and which couplers move a total of up to 48" between extreme buff and extreme draft positions.
