Granted: 1900-08-18
Abstract: 7106. Murphy, J. M. April 17. Electric railways on a sectional-conductor system with electromagnetic switches. Conductors; switches.-The switch magnets have fine wire windings 8 and thick wire windings 7, and the head 4<a> of the armature is always in contact with the contact 16 connected to the sectional conductors 5. The switch is excited in the first instance by a battery current from the vehicle flowing through the sectional conductor 5, contacts 16, 4<a>, spring plate 13<a>, and fine wire windings 8 to the return 1. This circuit is broken when the armature moves away from the adjustable plate 13<a>, but the main circuit is then completed between the contacts 16, 18 through the thick coils 7 from the feeder to the vehicle. To supply the battery current, the driver's controller has,.in addition to the regular resistance and reversing contacts for the motor, two steps which work on to the trolley and the battery contacts, so that the battery first supplies and then receives current from the trolley, which runs on the sectional conductors 5.

Abstract: 10,109. Dittrich, E. May 15. Circular knitting-machines.-Relates to means for transferring loops from one needle to another to make openwork patterns. The coverers c, c<1> and sinkers d are arranged alternately, and at intervals depending on the pattern to be produced, in tricks in a wheel D rotated by the bevel gear g, h, at a slightly less peripheral speed than the needle ring N. The coverers and sinkers are moved up and down and longitudinally by cams e,f, i, k, l, which do not rotate on the axle n. To transfer a loop, the coverer c' descends on to a needle a<1>, and the sinker seizes the fabric and lands it on to the coverer, which then rises. The difference of speed of the wheel D and the needle ring causes the coverer to lag and, when it comes down again and is moved forward, it puts the loop on the next needle a<2>. A push-back wheel s now forces back the fabric. A push-piece r may be used to assist the sinkers in landing the loops on the coverers. When making plain work, the push-piece r is put back out of action, and a push-piece q is used to push the fabric back out of range of the coverers and sinkers.
