Application filed October V17, 1917. .Seria-1No. 197,060.
To all whom it may concern:
Be it known that I, HERBERT E. VAN Donn, a. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Car Couplers, of which the following is a specification.
This invention relates to car couplers and has for its object to provide a new and improved device of this description. The invention is illustrated in the accompanying drawings, wherein Figure l is a plan view of one of the coupler heads of a car coupler embodying the invention; v
Figure 2 is a bottom view of the device shown in Fig.1; Figure 3 is an enlarged ing the air cylinder and associateduparts;
Figure at is a horizontal sectional view-of the coupler head shown in Fig. 1;
Figure 5 is an enlarged sectional view taken on line 5'5 of Fig. 1;
:F igure 6 is a view in part sectionshowing the two coupler heads coupled together;
Figure 7 is a sideelevation of one of the coupler heads;
Figure 8 is a front elevationof coupler heads; I
Figure 9 is a view showing the looking part. c
Likenu-merals refer to like parts through-' out the several figures.
one of the .Referring now to the drawings, I have illustrated a car coupler having the coupler heads 1 and 2. These. coupler heads are provided with the coupling "parts 4, which are rigid with the coupling heads and preferably integral therewith. The couphng part on one coupler head is adapted to project into the interior of the opposed coupler head as indicated in Fig. '6. \Vithin each coupler head is a locking part 5 provided with a receiving opening 6 for the coupling part on the opposite coupler head. In the particu,-
lar construction shown the locking part 5 is an. U-sha-ped piece of metal (see Fig. 9) and is pivotally connected to the coupler head by means of the pin '7, the pin passing throughthe looking part near its open end.
This locking .part forms, as it were, a yoke and the end is preferably left open to facilitate assembling the parts. Associated with each locking part is a spring 8 which SUP-w rounds a controlling part 9 pivoted at 10 with a pivoted piecell, which is also pivotdetail View show-.
ed on the pin 7. The pivoted piece is preferably provided With a retracting spring 12 which has one end engaging the coupler. head, the other end engaging the pivoted piece (see Figs. 3 and 4). This spring surrounds the pin 7 and I. prefer to provide. a
pler head. Said pawl isprovided with a controlling spring 27, one end ofwhich engages the pawl, a portion of the spring en= gaging the coupler head. The locking part 5 is provided with the stop 29 which is engaged by the pawl 25 when the locking part is in its unlocked position, the pawl holding said locking part in this unlocked position against the pressure of the spring 8. The pawl and the coupling part, it will be noted, mutually act to limit the movement of each other. The pawl 25 is also provided with engaging faces 30 adapted to be engaged by the coupling part as it enters the coupler head so that the pawl may be moved thereby to release the locking part 5 and permit it to move to its coupling position. I prefer to also arrange the parts so that the engaging face 30 of the pawl is engaged by the coupling part as it ismoved out of the coupler head so as topermit the free return of the locking part 5 to its coupling position.
The forward movement of the locking part is limited by the stop 31 on the coupler head. In the construction shown, the lug 31 is at the bottom of the coupler head. There is a similar lug opposed to the lug 31, just above it, the coupling part 4 passing between these two lugs when it is moved toits coupling position. The locking part 5 engages these lugs and they project inwardly, preferably substantially flush with'the top and bottom inner faces of the opening 6 in the locking part, or slightly above and-below the top and bottom of said inner faces so that the coupling part will not strike the top and I bottom walls of the locking part, that is, the
portion of the locking part opposite said lugs. By this construction the coupling part will slide freely into the opening of the locking part. The coupler head is provided back of the pawl 25 with a projection 32, against which the pawl strikes when it is moved to its outward limit, thus providing a solid foundation against which it rests when in this position. This is particularly" desirable when the pawl is moved against the stop by the coupling part striking it, thus helping to'move the coupling partlaterally to properly center the couplers. ch coupler head is provided with a stop 51, which stops the locking part 5 when it'is moved to its unlocked position. The coupling part 4 is provided with a beveled face 33 and a second finished beveled face 33 adapted to engage a finished beveled face 34 on the coupler head. The coupling part is also beveled at the top and bottom as shown at 35 (Fig. 7) and the coupler headhas beveled faces 36 at the top and bottom of the opening into which the coupling part passes (see Fig. 8). At the top and bottom of the opening of the coupler head I provide the finished faces 39 which are substantially at right angles to the faces 39, and substantially parallel to the finished faces 39 on the coupling part 4. These faces align the coupiers vertically and insure the proper align ment of the airtubes. These various beveled faces insure the centering of the coupling part. The coupling part 4 also has a finished beveled pulling face 37 which engages a finished beveled pulling face 38 on the coupler head. The beveled face 37 on.
the coupling part and the beveled faces 38 on the coupler head are all substantially parallel, and the beveled faces 33 and 33 on the coupling part and 34 on the coupler head are substantially parallel. The meeting faces 39'of the coupler heads are also finished surfaces. The parts are arranged so that when they come together a tight joint is made, there being substantially no.
relative movement between the two coupler heads after they are once coupled together. The ends of the air connections 41 and 41". for the brakes project through the wall 40 of the coupler head, that is, the wall contain: ing the beveled face 38. These air connec-' .are in their coupling position the inner face 44 of the locking part 5 engages the face 45 of the associated coupling part 4. These faces are arranged so that the locking part as it moves further along the coupling part forces the coupling part over so as to more tightly force the pulling face 37 thereof against the pulling face 38 of the coupler head, there-- by insuring a tight connection b'etweenthe coupler heads. This result may be secured by forming the faces 44 and 45 so that they are non-parallel. If, for example,the face 45 is a curved face, then this result may besecured by forming this curve, not about the pin 7 as a center, butabout a point a short distance ahead of this pin, that is, a point between the pin 7 and the coupling part 4.
It will thus be seen that by this construction the face 45 is on a'different curve from the path of the face 44, as it moves about the pin.
7 as a pivot. This construction keeps the engaging faces of the coupler heads in' close contact with each other, thereby preventngrelative movement while the parts are in their coupling position, thus preventing wear of the parts. I prefer to provide means for automatically uncoupling the couplers. In the drawings I have illustrated one form of' accomplishing this result. In this construction I provide means for automatcally. moving the locking parts 5 when desired to dis connect them from the coupling parts 4 as illustrated in Figs. 3, 4, 6 and 7. This dev ce consists of an air cylinder and suitable p:s
ton operatively connected with the lockingpart The cylinder 50 is provided with the piston 51, to which is connected the engaging piece 52, which engages the engaging piece engaging the pivoted piece 11, but separate therefrom. It will be seen that by letting air under pressure back of the piston 51-, the piston will be moved forward so that the engaging part 52 will move the engaging part 53, thereby moving the pivoted part ll'and the locking part 5 to the position shown in dotted lines in Fig. 6. This releases ,the coupling part and permits the couplers to be disengaged. As herein shown, the cylinder 50 is set into the coupler head and is provided with a removable end 54, theparts being held in position by -the bolts 55. Each coupler head is provided with an air connection 56 having a gasket 57 similar to the gaskets 41, the arrangement being such that when the two gaskets 57 are brought together in coupling the couplers, a
continuous air connection between the cars will be provided. These air connections '56 are connected to a suitable air pipe58 and they are connected by the connection 59 with the air cylinders 50. It will be seen that by controlling the air in these connections the air may be forcedinto the cylinders so as to automatically uncouple the couplers. It will be noted that the uncoupling mech ansim consisting of the cylinder and piston and associated parts is located inside of the coupler head and that the pivoted locking part with the receiving opening is also located inside of the coupler head so that this pivoted locking part adapts itself to this concealed enclosed and protected unlocking mechanism. This also saves parts, produces a cheaper and more effective construction,- and reduces the lability to injury and breakage.
When the .piston 51 and engaging part 52 are moved by the air pressure so as to move the forwarding part 53, said engaging part moves the locking part 5 and the controlling part 9 without moving the lever or handle-21, as under such conditions the controlling part 9 moves with relation to the pin 20 Without moving said pin or the actuating piece 23 connected therewith. The
" slot 19 in the controlling part permits this movement. It will thus be seen that the locking part 5 may be moved either by the handle or by the automatic device inde pendently without the one affecting the other. When the locking parts are unlocked so as to release the coupling parts 4 the coupler heads separated thus disconnectingthe air pipe and'permitting the air to exhaust from'the cylinders 50. The springs 8 through the agency of the engaging parts- 53 then move the pistons of the cylinders back to their initial position. It will .be seen that if the locking part is then moved by means of the handle the piston will stay in this initial or retracted position and does not depend upon the engaging part-53 to hold it in this position, it being held in such position until the air enters the cylinder. It will further be seen that while the two cooperating coupler heads have rode-- pendent unlocking mechanisms, these independent unlocking mechanismsare actuated by one operation, that is, by admitting air into the air pipe leading to the cylinders 50. lVhen this air is let into this pipe and into these cylinders by this one operation, the. two independent cylinders act upon their re-' spective mechanisms and thus unlock the coupler heads. For purposes of illustration I have shown a valve 61 (see Fig. 7.) for controlling the admission of air into the air pipe 58, said valve being-controlled by the lever 62. This valve would be located at a point where the operator of the train can easily manipulate it. I prefer to make the faces on the coupling part and the opposed partof the coupler head non-parallel. Referring to Figs. 4 and 6, I prefer to -make the opposied faces 34 and 33 inclined at a different angle from the faces 37 and 38, that is, non-parallel. I do not limit myself to any degree of inclination but in order to more clearly bring out this feature I may, for example, have the faces 34 and 33 inclined atan angle of 41 degrees and the faces 38 and 37 inclined at an angle of 45 degrees. This construction makes the coupling easier and prevents the coupling part from striking the corner 66, thus giving a clearance in coupling the coupler heads and preventing the battering of the points '66 of the coupler heads. These faces alsobring the coupling parts 4 when in their coupling. position inthe center of the opening between the guide lugs 31 and prevent the bottom therewith, a pivoted locking part contained.
within said hollow coupler head, said looking part adapted to engage the coupling part of the adjacent coupler head,v and a fluid actuated unlocking device for moving said locking part to its unlocked position, said unlocking device contained within said hollow coupler head between said locking part and the front endof the coupler head.
