Abstract: A railroad switch actuator has a transversely extending box sleeper having a pair of ends, adapted to be secured to a pair of longitudinally extending fixed rolling rails, and adapted to slidably support a pair of longitudinally extending and transversely shiftable switch tongues. A switch rod extends transversely in the box sleeper, is connected to the tongues, is centered on a transverse axis, and is displaceable along the transverse axis to shift the tongues. A drive having an output shaft is supported on one end of the sleeper by a hinge for pivotal movement between a down position outboard of the one sleeper end and with the output shaft axially aligned with the switch rod and an up position between the sleeper ends.

Abstract: With a device for switching switch tongues the tongue tip of which lies on a roller plane of a slide chair, the switch tongue can be switched more easily when the front roller (7a) of a roller pair (6) is positioned lower than the rear roller (7b).

Abstract: A track system has sleepers of predetermined width and at a predetermined spacing and a pair of running rails fixed to the sleepers. A switch has inner and outer transversely displaceable tongues engageable with the running rails and a pair of parallel hollow box sleepers of the predetermined width and at the predetermined spacing fixed to the running rails and on which the tongues are transversely displaceable. A drive rod extending transversely in one of the box sleepers is connected to both of the tongues so that a drive connected to the drive rod can transversely shift the tongues. Inner and outer position-monitoring rods extending transversely in the other of the box sleepers are connected to the respective guard rails.

Abstract: In a point-operating device for pressing one tongue (28) against a stock rail (3) and for simultaneous pull-off of another tongue (29) from an opposite stock rail (4), the operability is improved when between the stock rails/tongues of a point, a moving device, which is formed with at least four adjustable vertical spring assemblies (8, 9, 12, 13), is arranged.

Abstract: A guide-rail assembly has an anchor plate having an upstanding flange with a transversely directed face and formed below the face with at least one transversely throughgoing hole and a guide rail above the hole and having a transversely directed outer face bearing transversely on the flange face and an inner face directed transversely oppositely. A J-bolt has a bearing face directed transversely toward and bearing on the guide-rail inner face and a shank extending through the hole below the guide rail. A nut threaded on the shank and engaging an outer surface of the plate presses the J-bolt bearing face against the guide-rail inner face and clamps the guide rail against the anchor-plate face.

Abstract: A support plate, particularly a ribbed plate for fastening rails of railroad tracks and track switches on wooden sleepers. The support plate is connected in the vicinity of its ends, in each instance, with the wooden sleeper by means of screws or the like which engage in the through-holes, whereas the rail flange is supported in each instance in the area of the plate between the fastening points on the sleeper side. On the underside of the plate, shoulders are provided or constructed only in the area of the through-holes for the fastening screws, which shoulders project out of the plane of the plate and have a thickness of approximately 1 mm to 2 mm. As a result of the cooperation between the shoulders and the fastening screws, the support plate has a convex curvature, so that its underside comes in supporting contact with the upper surface of the wooden sleeper.

Abstract: Apparatus for fastening rails on ties of a railroad comprising four rail screws for flushly mounting an abutment face of a bedplate against the upper surface of the tie and a pre-stressed, elastically deformable bedplate having a convex curved abutment face for frictionally engaging the upper surface of the tie and for applying a spring force against the rail screws when the rail screws are used to brace the curved abutment face flush against the tie.
