No. 19778.—17th July, 1905.—JAMES DUNBAR, of Invercargill, New Zealand, Mechanical Engineer. Improved grip for rake-heads, spade-handles, and the like.

Extract from Specification.—The essential features consist in two exactly similar parts bolted together, between which are first placed the parts to be connected. The parts engaging the handle or shank are half-tubular, and branching out therefrom to the head or hand cross-piece, as the case may be, are two arms; the parts actually engaging the head or hand cross-piece are angled to prevent turning, and the head or hand cross-piece angled to correspond.
[NOTE.—The above extract from the specification is inserted in place of the claims.]

No. 19793.—26th July, 1905.—HILARY QUERTIER, of Woods’s Hotel, Dunedin, New Zealand, Engineer. Improvements relating to trolley-poles for electric traction.*

Claims.—(1.) In the construction of trolley-poles in which the upper member of the pole slides telescopically into the lower, the employment of a slidable member which is sided in section, and a cap upon the receiving member to guide said sliding member, substantially as described and illustrated. (2.) For the purpose indicated, in combination, a lower tubular member pivotally mounted at its lower end in a bracket upon the roof of a car, means which normally tend to cause said member to assume a vertical position, a sided member telescoping within and having a plunger fitting the lower member, a cap having a sided hole to receive the sided member, a spring operating upon said plunger, a head upon the end of said sided member, a trolley-wheel revolvably mounted in the head and roped, guided by sheaves, for operating the pole, substantially as specified and illustrated.
