Abstract
491,301. Escalators. WAYGOODOTIS, Ltd. March 17, 1938, No. 8246. Convention date, May 20, 1937. [Class 78 (i)] The wheels of each step are maintained in contact with their tracks by resilient means. In the form shown in Fig. 3, each stop 10 has in addition to the usual chain wheels 20 and trailer wheels 23, a wheel 26 which runs on a track 27. The wheel 26 is mounted on a stub shaft 29, Fig. 2, carried by an arm 30 of a lever 31 which is pivotally mounted on the axle 21 of the wheels 20 between the brackets 18 supporting the step frame. A channel shaped member 33 extends between the brackets and is apertured to receive a stud 35 secured to the part 36 of the lever. A spring 28 in a state of compression is placed between a washer 38 on the stud and the channel member, and maintains all the wheels on their tracks. In other forms an additional pair of wheels is provided and compression springs are placed between the pivoted arms carrying these wheels and the members in which the other pairs of wheels are mounted. In all forms sound deadening material such as synthetic rubber is provided on one of the surfaces of contact of the chain rollers with the teeth of the sprocket wheel.
