The `Schedule referred to in these Lettere Patent and malszlngpaxt of the same.

.To allwhom Iit may concern.-

Be it known that I, RICHARD KQ VESTL, of the .city and county of Santa Cruz, -State of California,

have invented an Improved Adjustable Grange for Setting Axles; and I do her'eby declare the following description and accompanying drawing ,are suiicie'nt to enable any person skilled in the artnr science to which it most nearly appertains to make end use my said invention or improvements without further; in-

Ihe object of'- my invention is to providea univer-i sal gauge for setting theaxles of common roadvehicles, by which I am enab1ed,'iilst, to` set the axle to suit the taper ofthe spindle; and secondly, to suit the disk of thewheel; andlastly, to suit the gather of thewheels, or the slight tendency tordu together, which figs given eaclrpair of wheels 'on the same axle fo'll the purpose ofmaking them run easily. Refel:ring to theaeoompf'myingdrawing'ora more complete explanation of my invention- Y A is a bar of metal or wood, made longer than the longest diameter of a wheel ordinarily used, and'. also ,long enough to include anyordinary length of' axle.

This bar' has arms, bland c, extending at iight angles to it from one end, while the other end carries an adjustable slidingar'm or bar d. Nearthe point Where the arms b and c meet the 'bar A, two bars ov plates, e andf, are pivoted to one side of the bar A, the bar extending some distance along'4 the bar A, and held'at any desiiedpoiut or slight angle with the bar A by a set-screw, g. l '.'This bai` e also carries an adjustable arm, h,`the' ptierpose of which will be more fully described herea r. The outer ends of the plates e and f are adjust-ed uponeach 4other from side to side by means of a setscrew, z', moying ina transverse slot in onetot' the plates, so that'they can" be clamped atany point upon .each other.' Upon theopposite1 side of the barA, ti'om thetwo. arms e and f, and held by vthe'same piu, is a third am, m, whichA is also movable from vside to side l about4 its point ofattachmeut, anr1 is heldfby ajsetsex-ema, 'The point ofran L-shaped ba'r, o, is pinned tothe extremity of the -arm b, `while the .other end o fthe angle has a piu 'passing through it so as to slideina sint, p, on the arm or-bar f.

" A similar-shapedbar, q,`is pinned tothe arm'c, andi I has its opposite end made tomove by means of a pin in a slot,"r ,in the plate or-arm m.

The operation will vbe as follows:l

Thearms e, -f, andm being -set parallel and the arm f is moved over the arm e, about their with the v bar A and with each other, the set-screw i, is loosened common center, till. the scale s shows an angle equa, to half lthe taper of the spindle', the' reading being' l taken at a'point opposite thetraiisverse scale t which vshows the length of' the spindle'. Y

These two plates are then secured together by their setfscrews'i, and the screw 1t is loosened.v The arm m is then moved about itspoint of attachment till its angle with thescale'u on the .bar 4A shows one-half the taper of thespindle less the gat-hen? (before described,) whichl itiis determined to give the axle. The

V-strew n is then 'made fast, and the'arms o and q will then stand with their sides at an angle with lines which are parallel with the bar-A.

The bar A' is vthen turned over, as in g.- 2, and the felly of the wheel is made to rest in the spacc'V, and againstthe side of the bar A, near thel adjustable arm d, so that the edge ot' theV bar A extends across the .disk'ot' the wheel just above the hub;

The bar or arm h is then set at a point ou the arm e, opposite the center spoke, above the hub o'f the V wheel; and-tile screw, g being loosened, the ann e is '.moved toward the wheeltill the end of' the gauge h v touches the center spoke( This movement will carry the outerlend of' the arm ein the opposite direction,

taking with 'it the arms f and the guide o; The screw g'being set again, (when the gauge h touchesY the spoke, as described,) the guide orfarin o will bein the, exactposition to set .the-spindle in a vertical plane v while the guide 'q willbe adj usted to 'set it in the horizontal' plane.`

The first adjustment is made by first'moving the .bar d till one collar of the axle .rests against the lug fw and the other collarrestsiu the notch 'az-at the end ofthe guide o. 1 -The axle is placed with the lower side ot the spiudleagainstthe guide o, 4to which it must be made to 'confor-m by bending the axle. This being accomplished the axle'will be set in that direction.- 'It must then be brought against the guide q,'the

side 'of the spindle touching and the collars'resting in the notch Z on the lug W'. Y 4 The springs Z' are .made to stand at an -angle above and below the' guide q, but their edges are in-the same plane, so that the axle can be exactly fitted notwlthstanding its set inptheiothei" direction.

This iinisbes one' end, which is then allowed to cool, and the other end is-heated and set in the same .Y By this 'device I- am enabled to set axles rapidly and4 -accurately,1 withoutany labor in ldrawing and laying out angles.

Having thus described my invention,

vfhat I claim, and desire to secure biuation with the adjustable vibrating gauge-arms e.

amf; substantially as amd for the pulpos@ herein degw'ribed.

2. The adjustable gaugearm m and the guide q, in

ombiuamion with the bar A, susic-antially as and for f In witness that the al'love-descrined invention is claimed by me' ,ll have hereunto. set myrhand and seal.
