I' have therefore promdedari adjustment for one side only, makingfone guide 15, movable and the other one, 14, substantially fixed. Upon the side frames 2 I make bearing-surfaces 24. On ,the bearingfsurfaces upon the left-hand side of the machine, as seen in Fig. 1, I place the groovedguide 14 directly against t e bearing-surfaces 24, and it is held firmly in place by the bolts 18. A coarse adjustment of this guide 14 may be obtained, if necessary, by placing shims between the bearing-surface 24 and the back side of the guide 14; but in ordinarypractice I find this unnecessary, the proper location being first obtained by machining the parts, after which it is not usually necessary to disturb them.
IOO
On the `right-hand side of the engine, as
eveeqll.,
shown in Fig. 1, I interpose a wedge 25 between the bearing-surfaces 24 and the guide 15, the guide being made with its back surface at an angle with the line of the groove 5 17, thus making the guide 15 substantially wedge-shaped and corresponding with the wedge 25. By this means the groove 17 is always maintained in a position parallel-with its original position, which is necessary for 1o proper adjustment of the guides. The wedge 25 is of substantially the same length as the cross-head guide, and the angle of inclination of the inclined surface ofthe Wedge is very small, thus making a very delicate M .il adjustment of the guide 15 possible and supporting the guide throughout its entire length. The wedge (see Fig. 3) is provided with two slots 26 to permit the vertical movement `""2 of the wedge with relation to the guides 15 zo and bearing-surfaces 24 on the side frame and at the same time to guide the wedge in its movements.' These slots 26 are of 'a width "substantially equal to the diameter of the i bolt 18 and of any convenient length. n 25 Upon the side frame 2'at a vconvenient point above the upper end of the wedge 25 I provide a lug 27 for the guidance of the adj justing-screw 28. This lug 27 has a vertical hole drilled and tapped therein, in which I k'.swo'linsert the screw 28, whose lower end rests "against the upper end of the wedge 25. The upper end of this adj usting-bolt 28 is provided with a hexagonal head 29, by means of which j), it may be turned in the lug 27, thereby driving the wedge 25 downward. To prevent the adjusting-screw working loose, I provide set-nut 30, which bears when screwed up against ythe upper surface of the lug 27.
Myimproved guides are adjusted in the I4o following ifrnanner: The cotters 23 are removed. The check-nuts 22 and the nuts 21 are loosened' slightly, allowing a slight movement'of the 'guide 15 toward the cross-head i 10. The check-nut upon the adjustingbolt 28flis also-loosened and the bolt 28 rotated slightly, :thereby driving the wedge 25 downwardiand forcing the guide 15 toward the cross-head 10. The various nuts upon the adjusting-bolt 28 and the guiding and supporting bolts 18 are then tightened and the cotters 23 replaced. By this means an accurate and delicate adjustment of the cross-head guides is obtained at a minimum expenditure of time. All the parts are held firmly in place, and there is no possibility for rattling or loosening of the parts and the consequent trouble arising from the continual jarring of the machine.
What I claim is- 1. The improved ball-bearing cross-head guides for a steam-engine comprising essentially a wedge-shaped guide grooved in the shape of a ball and tapering toward one end, bearing-surfaces upon the frame of the machine, and a Wedge between the said grooved guide and the said bearing-surfaces and movable longitudinally with relation thereto.
2. The improved adjustable ball-bearing cross-head guides for an engine, comprising essentially a wedge-shaped grooved guide, bearing-surfaces upon the frame of the machine, supporting means for the said wedgeshaped guide, and a wedge tapering toward one end between the said guide and the said bearing-surfaces, said wedge having slots therein to admit the supporting means for the said guide.
3. The improved ball-bearing cross-head comprising essentially a wedge shaped grooved guide, supporting means therefor,
'one-or more bearing-surfaces upon the frame 'oflthemachina a wedge tapering toward one end between the said guide and the said bearing-surfaces, and actuatinor means therefor'moving the said wedge oiwitudinally with relation to the grooved guide and the bearing-surface.
f Intestimony whereof I aHiX my signature in presence of two witnesses.
