Abstract

407,212. Electric trolly poles. GUY, S. S., Sauchieleigh, Albrighton, near Wolverhampton. May 4, 1933, No. 12972. [Class 104 (iii).] In a swivelling base of a trolly pole of the kind in which the pole is held up to the wire by springs connected at one end to an elbow i at the pivoted end of the pole c, and at the other end to a crosshead e adjustably mounted on an arm f carried by the swivelling base a, a single central point contact is arranged between the end v of the arm a and a flat or spherical thrust pad w in the adjusting sleeve u. A lubricating nipple y may be provided at the end of the sleeve.
