Abstract: An anti-spin or stop mechanism for a railway car door includes a rotatable ratchet wheel having radially outward extending teeth on the outer circumferential surface, and first and second pawls mounted in side-by-side relation on a common pivot pin for engaging the ratchet wheel teeth. The ratchet wheel is commonly mounted on a shaft with a lever or handle used to activate a drive mechanism for partially opening or fully closing the door. The pawls are continuously urged toward engagement with the ratchet wheel so that one of the pawls is always disposed in engagement with a ratchet wheel tooth while the other pawl rests against a land between two adjacent teeth. Each tooth has a leading edge and a trailing edge configured so that the pawls may act against the teeth trailing edges to prevent movement of the ratchet wheel in one direction of rotation while permitting rotation over the leading edges in the other direction of rotation.

Abstract: A module is provided for use with a drive mechanism particularly suited for plug-type railcar doors to prevent “overspinning” and “drifting.” The mechanism disclosed is a double brake-type mechanism and includes a first rotatably mounted member. The first member is arranged to transmit force in either direction of rotation and is connected with an input drive mechanism. The drive mechanism includes a rotatable pinion gear carried on a rotatable input shaft extending generally parallel to the axis of rotation of the first member. The pinion gear is connected with the shaft by means which cause it to move longitudinally of the shaft to a first or a second spaced point depending upon the direction the shaft is rotated. At each of the points, there are ratchets which are freely rotatable relative to the shaft except when the pinion gear moves to engage them at their respective points. When engaged, the ratchets permit movement of the shaft only in one direction.

Abstract: A railcar door assembly includes a drive mechanism operably connected to elongated support members for selectively imparting rotation of movement thereto, and a retarder assembly for preventing movement of the drive mechanism beyond defined limits. The drive mechanism includes a gear segment mounted on a bearing plate, and the retarder assembly is comprised of a pin and a retarder block. The pin extends through openings in each of the retarder block and bearing plate. The gear segment is rotated until a lobe of the gear first contacts and then compresses the block, thereby preventing further rotation of the gear segment. This arrangement effectively prevents undesired drifting of a railcar door into the side of the railcar itself.

At least one shaft having a vertical axis is rotated about the vertical axis by the securing mechanism, the shaft has first end and a second end such that each end is respectively coupled to the rail assembly, the rail assembly has a rail system which is positioned at a top end and at a bottom end of the door and are mounted on a housing.

Abstract: A weatherproof sliding closure such as a window, door or hatch, especially suitable for closing openings in a marine environment, is disclosed. The closure is mounted top and bottom on bearing assemblies via camshafts extending through the closure and rotatably mounted in the assemblies. The bearing assemblies travel along fixed top and bottom guideways to move the closure between open and closed positions with respect to the closure opening. Cam portions of the shafts act against internal portions of the closure itself, serving as cam followers, when the camshafts are rotated in unison in the same direction through operation of a closure handle and drive train interconnecting the camshafts internally of the closure. This causes the closure to shift laterally on its bearing assemblies into sealing engagement with a closure frame defining the closure opening.

Abstract: A sliding patio door assembly is disclosed of the kind in which the door, when it is being closed, moves bodily laterally with respect to the slide track; i.e., forwardly with respect to the closing door panel. When fully closed, the door is entered into a recess, and a weather seal is compressed between the door and a lip surrounding the recess. The door is controlled, as to its lateral movement relative to the slide track, upon crank arms, and it is a feature of the disclosure that the crank arms are constrained to pivot in unison but in opposite senses of rotation. Another feature is that the crank arms lie at 90 degrees to the line of the slide track when the door is fully closed.

Abstract: A sliding door panel is provided which moves bodily into and out of a recess so as to be closed or open, and when out of the recess it may be rolled sideways clear of the recess for ingress or egress therethrough. The moveable door panel is provided with a pair of crank shafts which carry crank arms, and one mounted so that rotation of a door handle causes rotation of the crank shafts and arms. The crank arms are each fixed at one end relative to the door, and at the other end relative to a track so as to cause the bodily movement of the door. The crank arms are also co-operatively associated with latch bars which enter latch slots at both the mullion and jamb sides of the door, so as to assure positive, intruder-proof latching of the door panel when closed.

Abstract: This sliding door as disclosed is of the kind where the door moves sideways relative to the slide-track and into a recess, upon closing. The door is mounted on crank-arms, which are turned by means of a door-handle. As disclosed, the door handle also includes a latch. A first part of the motion of the handle unlatches the latch, and subsequent part of the motion of the handle turns the crank-arms. This sequence makes it possible for a further latch to be provided on the mullion side, which can be also operated by the door handle.
