METHOD OF UNITING- A FLEXIBLE TO A SOLID BODY.
Specification of Letters Patent.
Patented Nov. 17, 1908.
Application filed March 14, 1908. Serial No. 421,130.
To all whom it may concern:
Be it known that I, CYRIL' DoUciJAs Mo- CoUR'r, a subject of the King of Great Britain, residing at 13 Malwood road, Balham Hill, London, England, have invented acertain new and useful Method of Uniting'a Flexible to a Solid Body. Y
This invention relatesto improvements chiefly designed for attaching flexible conductors to the carbon commutator brushes of electrical machines but also applicable for uniting rods or wires to carbon blocks for other purposes or to blocks of other materials. According to this invention I form in the block, to which the wire or rod is to be connected, a cavity, preferably, of a section correspondinglto that of the wire or rod but somewhat larger than the latter, the said cavity, if desired, having its walls undercut. Into this cavity the wire or rod, the end of which may beupset or splayed out if desponge, metal or alloy, in a powdered or fragmentary form, is now compressed by, means of a punch. or'other suitable instrument so, as to consolidate the metallic powand the we s of the said recess.
In the accompanying drawing :Figure l is a sectional elevation of a commutator brush having .the flexible lead applied according to my invention, and Fig. 2 is a plan of the same. Fig. 3 is an enlarged view of a modification of the device.
hole boredor otherwise formed therein and adapted to receive the end of the. flexible lead 0 the end of which, asshown, is upset.- d is the metallic. filling which is introduced into and compressed, in the hole 6 around the lead. i p The. powdered or fragmentary metallic sponge, metal, or alloy employed must be of idate when com-' Thus, granulated aluminium, granulated lead, granulated tin and the like maybe .employed or spongy'c'opper produced by the.
reduction of copper oxid. Where the body to which the wire or rod is to be attached is not very strong, as for example a carbon commutator brush, it is advisable to select a powder which does not require too severe a compression; accordingly, in the case of carbon brushes, I prefer to use the powdered spongy copper above referred to,
rather than granulated aluminium. Were brush without'the necessity for applying a v .metallic coating to the brush as has hitherto generally been considered necessary.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. The method of attaching a flexible to a solid body, consisting in forming in one of such bodies an aperture larger than the part of the other body which is inserted into said aperture, filling the space between the two articles with a substance of a nature to be consolidated by pressure, and in a finely powdered condition and consolidating this fill-- v ing, substantially as described. a indicates thebody of the brush and b a .2. The method of attaching a flexible to a solid body, consisting in forming in the solid body an aperture larger than the part of the flexible bod which is inserted into said aperture, fillin the s ace between the two articles with a metal ic substance, of'a nature to be consolidated by pressure and in afinely powdered condition and consolidating this filling by pressure, substantially as described.
