摘要： A handrail for transportation apparatus, such as escalators and moving walks, which includes an elongated, extruded elastomeric member having first and second wear strips fixed to inner surfaces of the elastomeric member for contacting a handrail guide. Each wear strip has a substantially U-shaped cross-sectional configuration, including a bight and spaced leg portions, and , in addition to providing low friction wear surfaces, the configuration aids the handrail in resisting derailment from a handrail guide. At least one leg portion of each wear strip has a plurality of spaced slots, or thin webs, which extend inwardly from the end of the leg to facilitate flexing of the elastomeric body member while traversing curved portions of a handrail guide. In another embodiment, a plurality of relatively short, discrete wear strips are spaced apart to collectively define an elongated wear strip, with the spacings being selected to function as flexiblity imparting slots.

摘要： A method of splicing a length of extruded handrail having a C-shaped cross-sectional configuration, a substantially flat inner drive surface, and a plurality of spaced, longitudinally extending inextensible members embedded in the body of the handrail. The ends of the handrail are squared, aligned, and butted. Longitudinally extending grooves are cut into the flat drive surface, through and on both sides of the butt joint, in the spaces between the embedded inextensible members. Predetermined lengths of inextensible members and elastomeric material are placed in the grooves, and bonded to the surfaces which define the grooves. In another embodiment, the grooves are extruded into the flat drive surface at the same time the handrail is extruded. In either embodiment, the ends of the handrail may be bonded together prior to, or simultaneously with, the bonding of the inextensible members and elastomeric material with the groove surfaces.

摘要翻译： 一种拼接一段长度的挤压扶手的方法，其具有C形横截面形状，基本上平坦的内部驱动表面以及嵌入在扶手的主体中的多个间隔开的纵向延伸的不可伸展构件。 扶手的末端平直，对齐和对接。 纵向延伸的凹槽通过对接接头的两侧，在嵌入的不可伸展构件之间的空间中被切割成平面驱动表面。 将预定长度的不可伸展构件和弹性体材料放置在凹槽中，并且结合到限定凹槽的表面。 在另一个实施例中，在挤压扶手的同时，凹槽被挤压到平面驱动表面中。 在任一实施例中，扶手的端部可以在不可伸展构件和弹性体材料与凹槽表面的接合之前或同时结合在一起。

摘要： A molded case circuit breaker is provided with a pivotally mounted contact arm assembly, formed as a clinch joint. The contact arm assembly is a bifurcated assembly formed from two coextensive members fastened together at one end defining a surface for carrying a movable main contact. The other end of the members is bent outwardly defining spaced apart arm portions for receiving a pivot bracket. The pivot bracket is provided with an aperture and aligned with apertures in the spaced apart portions for receiving a pivot pin and defining a pivot axis. The pivot bracket is rigidly connected to a load conductor. The current that flows through the contact arm is transferred to bosses integrally formed adjacent the apertures in the pivot bracket. Screw adjustable spring members are provided for adjusting the friction and the electrical resistance between the contact surfaces of the contact arm assembly and the bosses.
