4@uitrit gioire @stmt @fitta IMPROVEMENT IN ROILsR-rtns entsinne.,
ROBERT .KINGOF BROOKLYN, NRW YORK, iissIeNOR To. T. rROssRR-,a SON, Or NRW YORK O-ITY.
Letters Patent No. 60,013, dated November 27, 1866.
SPECIFICATION- TQ ALL WHOM IT MAY CONGERN:
Be it known that I, ROBERT KING, of Brooklyn, in the county of Kings, and State of New York, have invented `a certain new 'and isefu'l Improvement on Helical Wire Brushes; of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this speccation, and in Whichi Figure 1 represents a longitudinal view O''` a helical wire brush, constructed according to my improvement; and,
Figure 2, a transverse section thereof, taken as indicated by the -line :v :vin tig.` 1. Like letters refer to like parts in both figures. y Helical wire brushes, or'flue-brushes, as they are sometimes called from their use in cleaningouttubular boiler fines, have usually been constructed of steel wires of spring temper, made l'at at their ends, to act a's Scrapers or cutters, and arranged in the form of a helix round a twisted wire stock composed'ot` two 6r more strands, and serving to receive'between them and hold midwayof theirrlength the steel` wires of the helix'. An eye at one end of the stockiand screw-shank at the opposite end servewby means of a rope and rod orlrods, to
work and pass the brush through the tube or iiue. Such brushes, however; have been defective in the arrangement of the wire's of the helix, which should have i'ree open spaces between each other` at their working ends that require to be flexible, while theinterior portion of the helix around the stock should be close packed by the wires, so' as to form a rmer hold of the latter. This cannot be effected, however, or but imperfectly so, b y the present mode of construction; that is, by holding the several wires to or in the stock midway `of their length, and so that each twoadjacent ones project to an equal extent from opposite sides of the stock, as to leave suf-v ficient width of spaces between the wires at their working ends does not admit of sufficiently close packing of them around the core or stock to give thema steady holdv the one upon the other, and distributes the ilexibility too generally .throughout their length, while to arrange them in closer connection round the core brings their working ends too near each other to operatezwith the desired elect. This diihculty, however, my invention obviates; and it consists in arranging the brush-wires so that they protrude further from or on one side of the stock than on the opposite side, whereby a close packing of the wires is obtained at the centre around the core, and an open or free space left between them at their working ends. Y For the information of others whom it may concern, I will proceed to describe my invention, with reference to the accompanying drawing, in whichj i i A is the core, or stock, formed of twisted wire, or strands, in `the usual manner, and providedwith an eye, a, at one end, and screw-shank, b, at the other, to operate the brush as helical brushes are usually worked. The
core, A, has arranged round it in the form of a helix the spring-tempered steel,\virese c, d d, e e, ff, similarly,
so far as their general disposition and hold of them by the stock, through the strands of which they pass, t'o otherhelical wire brushes, but differing therefrom in the following important respect: The wires, which may beef equal length, instead of being held midway of their length, so as to project equally from opposite sides of thestock, are arranged to protrude more from one side than the other,-so that two adjacent wires Yform, the one a short and the other a long projection from or on the same side of the stogk, andv reverse projections respectively on the opposite sidethereoi', thereby making alternate wires to project equally, longer on .oneand` shorteron the other side of the core. In this way isa steady hold given to the wires by their close lapping or packing in the i central space lying between thecore and working ends of the wires, while said wires at their` working or outer ends have the necessary increased space left between them and desirable flexibility, by reason ofthe wires` alternately only protruding from the same side of the stock to form working ends, the intermediate wires not so protruding though similarly` projecting on the opposite side of the core.
What I claim herein asnew and useful, and desire to secure by Letters Patent, isf A helical wire brush, in which the wires are arranged to protrude unequally from opposite sides of the core or stock, substantially as shown and described.
ROBERT KING.
