lhis invention relates to liners andmeans for adjusting the same, and particularlyto y A further object, more specifically, is to provide a liner plate and a series of adjust-- able wedge members or liner wedges arranged to be shifted from time to-time to move the liner outwardly and thereby take .up the wear on the liner.

8 showing a further movement of the wedge Referring to the accompanying'drawings by numerals, 1 indicates the shaft of one ofthe driving wheels of an engine, and 2 a driv ing wheel connected with the shaft 1. r The driving wheel=2 is provided with a hubv 3 which would bear against the driving box 4 except for the liner 5. Theliner isprovided in order to take up the wear instead of the box 4. I-Ieretofore liners have been pro-f vided between the bearing boxes and the hubs of the driving shaft, whereby the liners Will take .up the wear, rather than the bearing boxes. From time to time new liners must be-provided. Inorder to do this, the locomotive mustbe taken to the roundhouse or other suitable-place andv the wheels dropped, as it isterm'ed in railroad parlance. The dropping of the wheels consists in moving the wheels and axles downwardly out of-the way so that the workman may have access to the driving box and may remove the oldliner' and place a new one in position. After this has been .done the wheels and axles are again lifted to their correct position and the parts se cured together in the usual manner. I The locomotive is'then in condition for further use. In the present instance means have been provided whereby the liners may be ad justed-from timeto timewithout dropping the wheels. In order to accomplish this result, a special liner 5 has been provided, and coacting with this liner are liner wedges 6 and .7 operated by suitable adjusting screws 8 and] 9. As these screws and wedges are identical, the description of one will apply to both.. As shown in F the wedges 6 and 'Z are fitted into oppositely inclined grooves and. llformed in the driving box 4. The grooves 10 and 11 taper from a central line 12 to the respective points 13 and 14, and at points 13 and 14 areshallowest. The liner 5 is formed to fit normally flatwise against the end of the bearing loox, as shown in Figs. 1 and 1. As shownparticularly in Fig. 1, the liner. isisub stantially U-shaped and the respective-legs 15' and 16 merge at the center of the top. and also merge into an extension 17 which is turned over for forming the stop or hook. 18 de-,

ed portion 4: of bearing box 4;, so that the liner res fPArsNroFFicE signed to engage the upper part of the round will not drop too far down when being installed. Each edge of the liner 5 is formed with a comparatively long flange 19 and a.

through the-respective slots 22; The lower end of each of the flanges 19 is formed with a verticalslot 23 merging into a laterally extending notch 24'. A bolt'25 extendsthrough the bearing box 4, through suitable'spools or washers 26 and through the; s lot 2 3 at the upper end. The notch 24 merges into slot 23 and forms in effect a lateral sl'ot .coactin'g with slot 22, whereby the liner 5. may be moved back and forth longitudinally of the axle 1. When the' liner is first placedin p0- sition it is placed in contact with the face of: the box 4, andas the hub 3 wears the same, liner wedges 6 and? are adjuste'd' soas to force'the liner away from box 4 more and more according to the amount of wear, and as indicated-in Fig. 4; The liners 6 and 7' are' identical in construction, except that one is the reverse of the other. Liner 6, as shown in Fig. 6 and in diagram in Figs/8 and 9 is an arc-shaped wedge having a flat surface-27 de-' signed to bear against the inner surface of the liner 5 and a pair of contact surfaces 28 and 29 adapted to] bear againstthe face of the driving box 4. The wedge 6 is also provided with a socket 30 adapted to receive the enlargement or head 31 carried by the screw 8. A neck 32 connects the head 31 to thebody of the screw so that the head may readily enter the socket 30. It will be noted that the socket 30 is providedwith an opening 33 and isopen atpoint 34, whereby the head 31 may readily enter and engage the upper wall 35' of the socket, as well as the lower wall 36. The opening 33' accommodates the neck 32 as the wedge is moved around in the arc of a circle during the adjustment of the various parts. It will be noted from Figsf3 and that the screws'8 afnd'9' are squared on the upper edge so that a suitable wrench may be fitted thereon, and these screws may be adjusted from timeto'time without removing the wheels and axles of the engine and even without running the engine-into the round- In the course of time the liner be- I house. I V comes worn, but the parts are so arranged that theliner can be adjusted to take up the slack as it occurs, and" when necessary the liner maybe removed and a new one inserted without dropping the wheels and with a minimum efiort; This may be done by removing the screws 21 and loosening the screw 25. n

When these members have been removed and loosened the plate 17 may be readily raised anda new one substituted and these members tightened and replaced. The screws 8 and 9 are screwed ina reverse direction back to their starting point when a .new iiner is placed in position, so that the action may be repeated on the new liner from time to time, as desired. During the use of the locomotive the wearing action on the liner 5 is the same as usual, but when this has become Worn to a certain extent a workman merely operates the screws 8 and 9 until the lost motion has tive from being laid aside for several days for eiiiciency the use of the locomotive. It also eliminates an appreciable amount of cost in 1 the upkeep and proper adjustment of the locomotive.

In Fig. 10 will be seen a modified form of liner in which the liner body 17 is substantially the same as liner 17, except that it is undercut grooves 38, whereby a casting of brass 39 may be cast directly to body 17 and thereby present a wearing surface. It will be understood that this form of liner, the form shown in Fig. 4, or other specific form of liner may be'used without departing'from the spirit of the inventiomprovided the same is mountedas set ferthand used alone or op- .er-ated in" connection with the wedges heretofore described. As indicated Figs. 3 and 4, the linerl? may be removed 'without droppingthe-wheels by merely loosening bolt 25, removing bolts 21 and then pulling upwardly on the liner. Anew liner may be supplied by reverse operation. 7 5

An end play liner for-locomotive driving boxes, comprising a liner plate, means for holding the plate in positiom'a pair of wedges coactin'g with the plate for shifting the same in a direction substantially longitudinally of the'locomotive axleto take up unnecessary play, means for guiding said wedges in arc shaped paths and screw means actingata tangentto said guiding means for-forcing said wedges along said paths;

2. An end play liner for locomotive driv-- ing boxes, comprisinga liner plate mounted on the driving box, said mounting permitting the liner to move longitudinally of the axle extending through the box, a pair of wedges carried by the box back of the liner, and a plurality of means acting on said wedgesformoving the wedges substantially in an are,

said wedges acting on said box and on said liner for shifting the liner in a direction longitudinally ofthe axle extending through the box, said means actingon said wedges including a screw for each wedge acting at a tangent to the wedge.

I

7. In a device of the character described, a liner, a wedge for shifting said liner, said wedge having a flat surface engaging with the liner, and an inclined surface on the opposite side, said opposite side being also formed with a socket having an opening at the top and one side, and a screw foractuating said wedge, said screw having a neck at one end merging into an enlarged head, said head being adaptedto fit into said socket, while the neck extends through one of said openings.

8. In a device of the character described, the combination with a locomotive driving box having an inclined groove merging into a depression of a liner for said box, a wedge fitting into said groove, said wedge being formed with a socket member extending into 7 said repression, and a screw carried by said box formed with a head loosely fitting into said socket, whereby as said screw is operated said wedge will be moved for shifting iaid liner longitudinally of the bore of said 9.
