WILLIAM J. 'WOQSTER, OF BIG SPRING, TEXAlS.

DEVICE FOR LINING- OF GROSS'HEAD GUIDE SHOES.

Application filed September 16,1925. Serial No. 56,780.

To all whom it may concern:

Be it known that '1, WILLIAM J. Woos'rnn, a citizen ofthe United States, residing at Big Spring, in the county of Howard and State of Texas, have invented certain new and useful Improvements in Devices for Lining of Grosshead Guide Shoes, of which the following is a specification.

This invention relates to a device for facilitating the lining of crosshead guide shoes with Babbitt metal or the like hearing material.

The cross heads of steam locomotives embody guide shoes which reciprocate on guide rails, and in order to reduce friction and insure extended periods of useful service for the shoes, they are lined on their hearing surfaces with some suitable bearing material, such as Babbitt metal.

The primary object of the present invention is to provide a simple durable and thoroughly reliable device for facilitating the application of the bearing material to cross head guide shoes.

A. further object is to provide a device of the above kind by means of which the bearing material may be applied on thebearing surfaces of the shoes in a uniform manner and accurately as to thickness so that no subsequent trimming or machinery operation is required to prepare the shoes for use.

A still further object is to provide a device of the above kind embodying a core plate adapted to be supported between the side or longitudinal guide flanges of a cross head guide shoe, said core plate being adjustable in width so that its side edges may be positioned the required distance from said guide flanges for accurately forming the bearing material of the required thickness on the inner faces of'said flanges.

Another object is to provide means for supporting and retaining the shoe and core plate in proper spaced relation so thatv the bearing material will be applied to the bottom surface of the shoe between the flanges of the latter at the proper thickness.

Still another object is to provide means to. adjust the shoelaterally relative to the core plate so that the guide flanges of the shoe may be positioned the same distance from the side edges of the core plate to secure similar thickness of the bearing material on said flanges. I

Other objectswill become apparent as the parts removed.

nature of the invention is better understood, and the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters indicate corresponding parts throughoutthe several views,

Figure l is a side elevational view of a device for facilitating the lining of cross head guide shoes constructed in accordance with the present invention and having a cross head guide shoe operatively disposed therein,

Figure 2 is an end elevational view of the device shown in Figure 1,

Figure 3 is a top plan view thereof,

' Figure 4 is, a substantially central longitudinal sectional view of the device shown in Figure 1, p i

Figure 5 is a transverse section taken substantially upon line 55 of' Figure 3,

Figure 6 is a view similar to Figure 5 taken upon line 6-6 of Figure 3, and

Figure 7 is a fragmentary plan view showing an end portion of the device with Referring more in detail to the drawings, the present invention embodies a rigid rectangular frame composed of guide members 5 and end members 6. The frame may also embody a bottom wall 7 for strengthening purposes, and said frame is adapted for supporting reception of the usual cross head guide shoe 8, the side portions of whichare adapted to rest upon the upper edges of the side frame members 5 as shown in Figures 5 so that the shoe 18' supported with its side guide flanges 9 projecting upwardly;

The frame is slightly longer than the guide shoe 8, and the end membersB have their upper edges in a horizontal plane slightly above the plane of the bottom bearing sur face of the shoe 8 when the latter is supported by the side frame members 5 as shown.

A core plate composed of

sections

10 and 11 is adapted to be disposed between the guide flanges 9 of the guide shoe with its ends resting upon the upper edges of the end frame members 6 so that the core plate issupported with its bottom surface in slightly spaced relation to the bottom bear ing surface of the guide shoe as clearly shown in Figure 4. The core plate is divided on an oblique line as indicated at 12 to provide the

sections

10 and 11, and the latter are slidably connected for relative longitudinal displacement along these oblique edges by means of a dove tail tongue and groove joint as generally indicated at 13. It is thus apparent that by displacing the

sections

10 and 11 longitudinally in opposite directions the width of the core plate may be increased or decreased as desired so as to position the side edges of the core plate the required distance from the inner faces of the side flanges 9 of the cross head shoe 8.

Pairs of transversely aligned nuts 14 are suitably journaled or swiveled upon transverse axes in the side frame members 5, and having threaded engagement with these nuts are screws 15 arranged to have their inner ends bear against the sides of the cross head.

screw 8. By properly adjusting the screws 15 transversely of the frame, the cross head guide shoe may be adjusted or shifted laterally relative to the core plate so that the flange 9 at one side of the shoe is positioned the same distance from the adjacent edge of the core plate as the other flange 9 thereof is positioned from the opposite edge of the. core plate.

It is thus apparent that by sealing the space between the core plate and the shoe at the ends of the latter with mud, wet asbestos or the like, the molten fabric metal or the like may be poured into the space so as to form a uniform lining upon the hearing surfaces of the shoe. When the metal has sufiiciently cooled the core plates may be reduced in width for facilitating removal of the shoe as will become apparent as the description progresses.

pair of horizontal longitudinally aligned

bearing sleeves

16 and 17 are swiveled as at 18 to turn upon vertical. axes, the bearing 16 being swiveled to the core plate section 10, and the bearing 17 being swiveled to the

core plates

6 and 11. An adjusting screw 19 has one end portion journaled in the bearing 17 and has its other end threaded and in threaded engagement with the bearing 16. A handle or knob 20 is secured upon one end of the screw 19 for facilitating turning of the latter, and it is apparent that the screw may be turned for effecting longitudinal displacement of the

sections

10 and 11 of the core plate in opposite directions for increasing or decreasing the width of the core plate as found desirable.

Suitable clamping devices are provided at the ends of the frame for engaging the ends of the core plates so as to rigidly maintain the latter in proper position relative to the guide shoe after being properly adjusted as to width. As shown, each of these clamping devices embodies a horizontal bar 21 having downwardly and outwardly projecting bearings 22 upon the ends thereof in which the end portions of a horizontal adjusting screw 23 are journaled, said adjusting screw having threaded portions inwardly of the hearing 22 engaging threaded apertures of clamping jaws 24. The jaws 24 project inwardly so as to enable the same to grip opposite sides of the adjacent end of thc corn plate as clearly indicated in several of the views, and the jaws also have upwardly pro jecting portions as indicated in Figure 4 which engage the outer edge of the bar 21 so that said jaws are prevented from turning about the screw 23. The threaded portions of the screw are respectively of right and left hand character so that when the screw 2?, is turned in one direction separation of the jaws 24 may be had, while rotation of the screw 23 in the opposite direction will effect simultaneous movement of the jaws toward each other into gripping engagement with the sides of the core plate. For facilitating turning of the screw 23, a hand wheel 25 or the like may be fastened upon one end thereof. Each end frame member 6 is provided with a pair of upstanding brackets or posts 26 upon which the ends of the bar 21 rest. and these posts 26 have threaded sockets 27 into which are threaded stud bolts 29. which extends and has threaded engagement with the ends of the bar 21. It is thus ap mrcnt that when the stud bolts 29 are tightened, the clamping devices may be rigidly fastened to the ends of the frame in such a manner that removal of said clamping devices with ease and facility may be had.

When the lining has been applied to the bearing faces of the shoe as pointed out above, the core plate may be removed after being decreased in width as was also pointed. out above, upon removal of the clamping devices from the ends of the frame by disengaging the thread bolts 28 from the frame post 26. When this is done the clamping devices are separately removed as a unit, and the removal of the core plate is then allowed so that the lined guide shoe may be subsequently removed with facility.

From the foregoing description it is believed that the construction and operation as well as the advantages of the present in vention will be readily understood and appreciated by those skilled in the art.
