Abstract: A coupler positioning device for long length railway freight cars comprising an elastomeric member having an upper surface connected to the shank of a coupler for lateral movement therewith. The lower surface of the elastomeric member is operatively connected to the adjacent truck and moves with the truck upon a pivotal movement of the truck relative to the car body or center sill. The elastomeric member deflects in shear upon any relative lateral movement between the truck and the coupler shank. After the shear deflection of the elastomeric member the coupler shank and truck are urged by the bias of the elastomeric member to longitudinally aligned relation.

Abstract: A tractor-operated hitch for supporting a trailer on a railway car is provided with a manually operated locking device for the trailer kingpin, in addition to the usual kingpin clamping jaws. The locking device includes a shaft or disc rotatable in the bottom portion of the supporting plate of the hitch below the jaws and has a C-shaped rim extending round the bottom of the kingpin. The locking device is turned by a handle so that the rim blocks the opening in the supporting plate through which the kingpin enters and leaves the supporting plate. The handle is arranged so that it can be operated fully only when the jaws are closed and locked, and thus provides a warning if the jaws are not locked closed.

Abstract: An angle cock for a trainline is mounted centrally of the width of a railway car generally beneath the coupler. The angle cock comprises a valve movable between fully open and fully closed positions and a valve stem extending in a horizontal direction generally transversly of the car from opposite sides of the valve. A handle is mounted on each valve stem and is pivoted outwardly from a releasably locked position before rotation of the associated valve stem. After rotation of the valve stem and valve to the fully open or fully closed position the handle is pivoted inwardly to releasably lock the handle in position. The handles on opposite sides of the valve are interconnected so that the unlocking of one handle effects unlocking of the other handle therefore to permit rotation of the valve. Upon rotation of the valve to the fully open or fully closed position, the associated handle is pivoted inwardly to a locked position and simultaneous locking of the other handle is likewise effected.
Abstract translation: 火车线的角度旋塞通常位于铁路车辆宽度的中心，通常在联轴器下方。 角度旋塞包括可在完全打开和完全关闭位置之间移动的阀和从阀的相对侧沿水平方向大致横向延伸的阀杆。 手柄安装在每个阀杆上，并且在相关联的阀杆旋转之前从可释放地锁定的位置向外枢转。 在阀杆和阀门旋转到完全打开或完全关闭的位置之后，手柄向内转动以将手柄可释放地锁定就位。 阀的相对侧的手柄相互连接，使得一个手柄的解锁能够实现另一手柄的解锁，从而允许阀的旋转。 当阀旋转到完全打开或完全关闭的位置时，相关联的手柄向内枢转到锁定位置，同时对另一手柄的同时锁定也被实现。

Abstract: A coupler-centering devices includes a rack on the bottom of the coupler shank having longitudinal gear teeth so that lateral movement of the coupler causes rotation of a gear segment. The gear segment is adjustably spring mounted and is connected to a torsion rod through a hand-operated clutch. The torsion rod extends parallel to the centerline of the car immediately below the coupler shank, and its inner end is fixed to the car. Alternatively, the rod may serve as a shaft to turn a torsional rubber shear structure. The teeth of the rack are long enough to permit buff and draft movement of the coupler.

Abstract: A retainer lock formed from a metallic one piece flat rectangular blank and adapted to fit over the end of a draft key of a railway car. The one piece rectangular blank is folded into a yoke-like member and has two punched aligned openings, one opening being circular and the other being elongate with an elongate tab formed from the elongate opening and adapted to be folded downwardly over an elongate head of a retainer pin in the aligned openings. A vertically extending projection adjacent each opening faces an adjacent center sill and the elongate tab forming the upper elongate opening which extends into the upper adjacent vertically extending projection thereby to permit a tab of sufficient length to cover a substantial portion of the width of the elongate head of the retainer pin.

Abstract: A coupler positioning device for railway cars comprising an elastomeric member connected to the shank of a coupler for lateral movement therewith and deflecting in shear upon such lateral movement. The lower surface of the elastomeric member is held against movement at a preselected position beneath the coupler shank and the upper surface of the elastomeric member is connected to the coupler shank for lateral movement with the coupler. Such lateral movement of the coupler is against the bias of the elastomeric member and the elastomeric member deflects in shear. After the deflection of the elastomeric member, the coupler is returned by the bias of the elastomeric member to the preselected position with respect to the longitudinal axis of the center sill. A coupler carrier adjacent the open end of the center sill is spaced from the coupler by the elastomeric member and acts as a stop to limit the downward movement of the coupler upon lateral swinging of the coupler and a vertical compression of the elastomeric member.
Abstract translation: 一种用于铁路车辆的联接器定位装置，包括连接到联接器的柄部的弹性体构件，用于横向运动，并在这种侧向运动时在剪切中偏转。 弹性体构件的下表面在联接器柄下方的预选位置处被保持抵抗运动，并且弹性体构件的上表面连接到联接器柄以与联接器横向移动。 联接器的这种横向运动抵抗弹性体构件的偏压，并且弹性体构件在剪切中偏转。 在弹性体构件的挠曲之后，耦合器通过弹性体构件的偏压返回到相对于中心纵梁的纵向轴线的预选位置。 靠近中间梁的开口端的联接器支架通过弹性体构件与联接器间隔开，并用作止挡件，以限制联接器在联接器的横向摆动时的向下运动以及弹性构件的垂直压缩。

Abstract: A NUT MOUNTED ON AN EXTERNALLY THREADED SCREW FOR RAISING AND COLLAPSING A TRAILER HITCH ON A RAILWAY CAR UPON ROTATION OF THE SCREW IS SUPPLIED WITH LUBRICANT FOR LUBRICATING THE SCREW UPON EACH CYCLE OF RAISING AND COLLAPSING THE HITCH. A SUPPLY OF LUBRICANT IS IN FLUID COMMUNICATION WITH A LUBRICANT WELL WITHIN THE NUT AND ACTUATING MEANS IS OPERATIVELY CONNECTED TO THE LUBRICANT SUPPLY TO FORCE UPON ACTUATION A PREDETERMINED AMOUNT OF LUBRICANT FROM THE LUBRICANT SUPPLY TO THE NUT. THE ACTUATING MEANS IS RESPONSIVE TO THE MOVEMENT OF THE TRAILER HITCH BETWEEN COLLAPSED AND RAISED POSITIONS AND IS ACTUATED UPON EACH CYCLE OF RAISING AND COLLAPSING THE HITCH THEREBY TO PROVIDE LUBRICANT TO THE NUT AND SCREW UPON EACH CYCLE OF HITCH OPERATION.

Abstract: A resilient air hose support for railway cars extending beneath the coupler between the coupler head and the air hose therebeneath. The support is formed of a rubberlike material and has a lower end portion connected to the air hose. The lower end portion of the support has a relatively wide intermediate section extending about the hose, an eye adjacent one end of the intermediate section, and a protuberance adjacent the other end of the intermediate section fitting within the eye and releasably holding the support in position about the circumference of the air hose.
