摘要： A safety system which permits the free movement of the user, assists the ascent of the user and provides a reduced, controlled rate of descent in the event of an emergency descent or a fall, includes a cable attachable at one end to the user and secured at the other end to a moveable counterweight assembly. Intermediate its ends the cable passes over a pulley in a controlled descent device which also includes a centrifugally-actuated clutch coupling the pulley to a speed-multiplying gearing system and a centrifugally-operated braking assembly. Under normal-use conditions, the pulley is rotated at sufficiently low speeds to preclude engagement of the clutch, and the user has free movement, with a component of the counterweight assisting the ascent of the user. In the event of a rapid rate of descent, the increased rotational speed of the pulley is coupled to and actuates the braking assembly to reduce the rotation of the pulley and slow the descent to a lower, controlled rate. Descent may be vertically or at an angle with a spring pulley and an angled descent cable. The cable may be disposed on the pulley in different arrangements, and the pulley may be provided with alternate groove configurations. The pulley may be coupled to the braking assembly without an intervening clutch.
摘要翻译：允许使用者自由移动的安全系统，在紧急下降或跌倒的情况下帮助用户的上升并提供减少的，受控的下降速率，包括一端可连接到使用者并固定的电缆在另一端到可移动的配重组件。中间件的末端是电缆通过控制的下降装置中的皮带轮，该下降装置还包括将滑轮联接到速度增速传动系统和离心操作的制动组件的离心致动离合器。在正常使用条件下，滑轮以足够低的速度旋转以防止离合器的接合，并且使用者具有自由运动，配重的部件有助于使用者的上升。在快速下降的情况下，滑轮的增加的旋转速度被联接到并致动制动组件以减小滑轮的旋转并将下降速度降低到较低的控制速率。下降可以与弹簧滑轮和成角度的下降电缆垂直或成一定角度。电缆可以以不同的布置布置在滑轮上，并且滑轮可以设置有交替的凹槽构造。滑轮可以联接到制动组件而没有中间离合器。

摘要： A novel controlled descent device is disclosed which not only aids in the ascent of a human being from a lower elevation to an upper elevation but also provides for the safe descent of a human being from the upper level to the lower level. The apparatus comprises a round cable, a counterweight, a controlled descent pulley having a ratchet and pawl brake system and a conventional pulley; all operating conjunctly dependently on the position and situation of the human being. The controlled descent pulley and conventional pulley are held in a plate structure which is secured to the upper elevation. The counterweight is raised and lowered from the upper elevation to the lower elevation and vice-versa by means of a guy wire which is anchored and held in relatively taught position between said upper elevation and said lower elevation.

摘要： Structures and apparatuses such as tank cars that have ladders associated therewith are disclosed which have, at the ladder top, two arrays of a plurality of horizontal rungs suitable for a climber using a ladder to horizontally grip by hand. The arrays form an opening through which a climber can leave or access the ladder while gripping the horizontal handgrip rungs of the arrays. The cross-section of the horizontal handgrip rungs is substantially round and should not exceed 2 inches in diameter. The preferred cross-section of the rungs is within the range of from about ¾″-1″ in diameter.

摘要： A fixed ladder has a first plurality of parallel rungs arranged along a lower section thereof and also has a walk-through section with vertical side rails arranged at the top thereof. A second plurality of parallel rungs is arranged along the walk-through section. This second plurality of rungs is attached at one end to the vertical side rails of the walk-through section and is easier to hold then the vertical side rails if a foot or a climber slips near the top of the ladder while mounting or dismounting at the walk-through section.

摘要： A safety rail assembly for mounting on a deck of a transport carrier which transports and supports thereon at least one automobile having at least one of passenger and driver-side doors. The portable safety rail assembly includes a handrail extending horizontally relative to the upper surface of the deck and support posts for supporting the handrail. Each support post may be removeably mounted to the deck to permit selective vertical displacement of the handrail relative to the upper surface of the deck for positioning the handrail at a desired height above the upper edge of a door of the transported vehicle. The desired height permits unobstructed opening and closing of the doors and safe entrance into and egress from the interior of the automobile.

摘要： Walk-through safety devices for ladders meeting ANSI and OSHA standards are positioned at the top end of the ladder and are comprised of two, juxtapose-position, mirror image members. One each is mounted on a respective ladder side rail, Each member includes a sleeve (or rectangular tube) which slides down over a respective ladder side rail, a pressure bar which is tightened against the side rail with a knob operated screw, a pivoting engaging lock plate, and a lock plate tab cover plate. A horizontal hand grip framework is held outboard of the ladder side rails vertically upward, being at an angle of about 14.5 degrees upward from the longitudinal axis of the sleeve and side rail when resting against a structure. The framework is held in that position by a flared tube which is bent in two directions.
