NEW TROLLY-HEAD FOR ELECTRICAL TRAMS.

Th® invention of Jfcmtrs Garnet TTolmca and Arthur Allen, of an improved nan-fouling troM.vhoad for tramways pnrpowa ha*s been nubmilted to one* of the most eminent electrical in thn oolonj. Ho pronounces it aa nn excoodtngij cl«v*r device, and exprwasee the opinion that jT will be univeraallj adopted. Through tho kindness of the tramway# engifiw of this city, the Invoatom wore able to make an exhaustive triad of tb* invention on Saturday had. when they put the trolly-bead to Umi most sevoro twta, which wore mie~ ceenfnlly negotinted to the great delight of all interested. .lodging from the satisfactory results, the uaccers of fcbo invention b aJnmwiy assured. On Saturday, the new trolly-head \voo fitted to ttno of the trajjway cars, which left the abode and travelled down Newtown to the Basin Reserve at full speed, negotiating 1 oii the overhead ears, ertwmings. nr itched and curves with such cwwjo and curtainty, Lhut it wan uecotwary to doliberatefjr ruako the head leave the trolley-wire, with a view to mom effectively tasting its naa-fotiling qualities. Thirl best proved to T»o most Hitwf&rtory, tho trolloy-boml slnUng beneath all the span wire obstructions, nnd putting through any pali-«ffs it ynat with. On the return trip, the polo wm again pulled off tho wire, and allowed to swing about am on gust the ovorTuMid wires -in bath Adelaide mad and Kicidiforci street, but nothing auCownrd happened, and the car reaches I the ttheds with the head intact. and in the same condition as it was when tho trial begun. 'Hie car then again travelled down NfWtmrn, slid tho head wns by special arrangement of tho inventoin. who wore present. pulled off the trolly-wire hi one of the previous obstruct turns, nnd a Rowed to act as though as accident had happened to the present brad. To prove that the non-Fotibng dovi<m wan one of the secrets of {he fiucc«wm of the new Invention over th*v prefjent system, the action of the above device waa ferrijurnniy KUspemled. allowing the head to work as under the pro* ffient wystoni, with the mm It that in. mediately it mot tho overhead vrirvss it became ontnnelcd, and tho usual accident happened. The now head :« designs] to proven! this, t saving an enormous annual outlay n<*v. imposed upou tramnay conip.inscM by tho recurrence of ivt* ions damagv to tho overhead wires, frally-homin. and tramway cars. Apart from thw iminm-e saving, the most hrpnrtnnt bsoi.-U;. to bo secured by tho adoption oi thin now trolly-bead u tho ctident ;o :• .. j Thin siucccwsfn] introduction in-spircs the invantnrs with tho confident hope that the opinion exby tho eminent engineer as to iti univunet! application win nt no distant date bo accomplished.
