C is a shaft passing;` transversely through the center of U, supported by 'and turning on the pivot-points of the screws J J, which work in female screws secured to the center to the shaft() has right and left hand screwscut upon it, extending inward from each end;

A. A are 'brush-wheels having female screws formed .in apertures in their centers', which are received. onto and lit the screws ou 'the ends of the shaft C. u

B is a grooved pulley made fast to the center of the shaft C. rEhe brushwhcels A A are retained in-their proper position, and made to turn with the shaft C by means of lthe rod Z passing through apertures in the pulley B and in each of the brush-wheels. The rod Z is kept in place by nuts working on 'right and left screws on each end of the rod. The bristlesI are inserted into theinner surfaces of the brushniheels, near their pcripheries, and the wheels are adjusted at such a distance from each other that the inner ends of the brushesof bristles meet and pass by each other for a short distance..

D D are straight brushes placed opposite to. and facing veach other in v tl 1e ofi'set'R', sup-vv ported. by the rods mm, which pass through the backs of the brushes, and have their ends made fast to theA sides of the offset. The faces of the brushes 'D D are pressed against each other with considerable force by means of the 'tra X represen'tedi i vThe mineure-.rsecties,apparatussul i" 'in Sitd .in 1101.12 t t el..

By this manner of securing' therbearing or sus,

pending'axles 'to the ypaintbox the apparatus;

can be readily placed upon or taken fronithe wires, and the' suspending-pulleys can be so adjusted in their positions as to cause the .wire

t0 bear with suiiicient force upon the pulley B von the shaft C to cause the brush-wheels A A t0 revolve as the apparatus is drawn along the wire.

a, is a signalbell suspended under one ofthe guides has shown in Figs. l and 3, which is made tering; at each revolution of the brushwheels by means of the projection i on theperiphery ofone ofthe wheels, striking' `against an arm descending from the spindle p, which spindleis connect-ed to the axle ofthe bell by the arms b b, and thus serves to indicate to the person who may be drawing the apparatus along the telegraphic wire that' the brush-y "wheels are in motion.

. The operation of my painting or coatingappuratus is as follows: The paintbox'having .been supplied with the requisite quantity ot' paint or other coating matter, the apparatus is placed upon the telegraphic wire or wire y cient lforce upon the pulleyB to cause 'its fric setR, which conducts it into tbe paint-box U.

cord, and the suspension-pulleys E E are so adjusted as to cause the wire to bear with suffition to revolve the brush-Wheels vas, thevapp'aratus is moved along the same. The rotation of the brush-wheels deposits' the paint upon the wire as the apparatus isl moved thereon, and the stationary brushesD D, between which the Wire then passes, serve to force the 'paint 0r other coating matter Ainto the in'terstices, Where several small wires are laid together i'nto a teegraphic cord, and also to remove the surplus paint and give a smooth surface to the wire or cord. The Asurplus ,paint or coating matter removed by the brushes D D from the wire falls into fthe inclined bottom of the oft'i The wire for telegraphic purposes Ycan be coated either before or after it is'suspended to the posts.=

By frequent painting or coating of' the telegraphic wires by the aid of my apparatus they can .at ansmalll expensev be preserved for a great lepgth of time,

What I claim as my inventi to secure by Letters Patent, is-l The construction'o'f an apparatus for aidingA in thepaintin'g or coating of telegraph wires (or for other purposes) by the combinationof rotating and stationary brushes, and suspension-pulleys, vor theireq'uivalents, able receptacle-for paint or other forth, not intending by 'this claim to limit my- -self to the part-icular form, number, and an rangement of the. parts lcomposing the appar ratus for aiding in the painting' or coat-ing of telegraph-wires, as herein represen tedand' de scribed, but to expedient, While 'I attain the s means substantially the same.
