' A'BJP'.IACEUMIENT DRIVING-BOXES.

Patented'aug. 2, 1910.-

To all 'it 'may concat-'.3

Be itiknown that-I, CHARLES MARKEL, a citizen of the United Sctes, -residing at Clinton, in the county of Clinton find State of Iowa,- have invented new and useful Improvements in vAttachments Boxes, of which the following is a specification.

This invention relates to driving box side motion plates for use on locomotive, engine truck and trailer boxes, or any axle box where there is wear between the hub of the Wheel and the side of the box resulting inlostorside motion.

The object of this invention'is to overcome the wear on the hub side of boxes by providing means Afor readily and economica ly tak- L ing up the side motion due to wear.

In the ordinary construction or that now commonly employed, Babbitt metal is applied to the hub side of axle boxes to obviate friction and wear, but when this metal becomes worn or broken it produces a side emotion whichl is very objectionable. To

' boxes, and renew the Babbitt metal.

overcome this side motion it is necessary to run 4a locomotive into a shop and dismantle the same or take out the wheels, remove the This operation-isvery expensive, as-it ,requires two or three days time with the constant loss o'f use of the locomotive. l

In the drawing: Figure 1 is a front elevation of'a driving tures of the invention. vation of the same. p view of the box'partially broken away and shown lin section. tion of one of the F ig. 2, is a side eleplates looking toward"tlie .y inner side thereof. 'FigA 5 isa transverse 6, and

vertical section throughv the plate showing the facing of Babbitt-metal therefor. Fig.'

6 is .a getail perspective view of a portion o f the 'riving box showing one of the side motionplates removed. Fig. 7 is a detail perspect1veview of the side motion .plate removed from Fig. 6. l

The structure ofthe driving box is in all particularsl similar to that ordinarily emplayed in--coperation with the axles of the wheels of locomotives, engine .trucks and traileiis, 'except in the specific'l particulars which will be hereinafter noted; and said driving box instance about five-eighths o flan incl'nfasat i an upperoverhang'ngor dovetailed for Drivingbox embodying' the fea- 3 is a top planl Fig. 4 is a detail .elevais designated by' the numeral-5f fplaned downylfpr.

l' enlarged to form a la large .enough to fiange 7 extending fully across the box is formed above the arch 8, and on the same side the legs 9 are formed with corresponding-or co eratin'g dovetailed iianges'lO., 'the removal o 4 the metal on the hub side of the box and the formation of the dovetailed flanges 7 and l0 roviding aseat for the receptlon of two side motion plates 11 which are duplicate in Aconstruction and join at their upper central portions as .at 12. Within the arch 8 the usual brass bearing 13 of arcuate form is tted and held. These plates 11 conform in contour to the seat in which they are removably fitted and are formed with semi-arcuate recesses 14 which jointly conform to the contour of the brass bearing 13, said recesses coinciding andlzreceiving, when the plates 11. are applied, the projecting portion of the brass bearing, as clearly shown by Figs. l and 6.

The upper and lower edges 15 and 16 of ate are beveled in lreverse directions each pl to correspond to and engage the dovetailed flanges 7 and 10, the plates being ap lied to the driving box from opposite s1 es and pushed fully tral portions as at 12 are pushed inwardly in full engagement withI each other. The face of each plate 11 has a Babbitt metal layer 17 applied thereto in themanner particularly shown by Figs. 4 and 5, key-.openinwardly until the upper cei ings 18 being formed in the plate at intervals so that; the Babbitt'metal will run through said openings, as shownby Eig. 5, and form keys for securely holdin 'the layer in applied position. The objecto this Babbitt metal layer on leach plate is to prevent friction and wear' between the. hub off'the wheel and the facel of the plate, and in the event that this layer wears down it ma be readily replaced at small cost. 11 are removably by boring a hole p per portion d'fgthe box 'and insertinga bolt the opposite extremity plate 11 having'a slot 23to .coincide 'withthe formed a slot The, r aiss secured to the drivingr box' 19 entirely across Vthe 'up-,'- 1

'100 20therein.: The hole 19 at one extremity'.i's-l i bon' had anni ami at "I is similarly Venlarged "bolt head-seat 21" and the other platef' is '24 to register.with-the` nut andwasher seat 22. The-bolt head '25 extend 'into the slot 23 and the'washer 26 is of such dimensions as.'

. to project intothe slot 24 so that when'the boltisutightehed up and the'nuts and washer y the 26 applied as shown by Fils. and 3, the

l plates 11 will be drawn in c ose engagement revented from havin movement until lt 20 isreleased an Withdrawn. It will beunderstood that the bolt and washer and 'Seat 22 and registering slot 24:4 will be large enough to permit the convenient ap lication 'and removal of the nuts with re ation to bolt 20 from the box, removing the plates 11 Sidewise and renewing the Babbitt metal on the plates and the latter redisposed in operative position on the box, or new plates ma)T be put in without requiring a dismantlin of the locomotive-or trucks and Wit-livery little delay or loss of time. v

The improved construction will be found exceptionally advantageous, a-nd it is obvious that modifications in the dimensions and proportions may be adopted to accommodate various applications. It will also be observed that there is practically no disturbance of the usual organization of the driving box with the exception of the forplates, as hereinbefore explaine What is claimed is:

A11 axle or driving box having the usual arch and an opening extending from the arch throu h the bottom of the box, the hub side of the X being'plan'ed down and having an upper overhanging dovetailed` {iangeV i and lower coperating dovetailed flanges,

and a plate secured to the hub side of the box and composed of sections having the upper and lower ends thereof engagingthe dovetailed flanges and the inner portions conforming'to the contour of the arch and opening, t e sections being removableside- Wise from the box, and means for holding lEhe sections' applied to thehub side of the In testimony whereof I have hereunto set my hand in presence of two subscribing wvitness'es.
