SELF-OILING-CBOSSHEAD GIB.
Application filed June 13, 1925. Serial No. 36,990.
The primary object of this invention is in providing improved means for oihng the guiding surfaces of the cross-head guides with which the gibs of the cross-head are cooperable. v
Another object of the invention is in providing improved means for oiling the lower guidin surface of the upper cross-head guide of a cross-head.
A further object of the invention 1s 1n providing improved means which are borne by the cross-head gib having resilient contact with the guide of the gib for oiling the guide and gib.
It still further object of the invention s 1n providing a cross-head gib with an oiling roller which cooperates with the lower surface of the cross-head guide and an oil chamher in the gib.
Other and further objects will appear in the specification and be specifically pointed out in the appended claims, reference being had to tl'ieaccoinpanying drawings exemplifying the invention, and in which,
Fig. 1 is a side elevation of a cross-head having the intermediate portion thereof broken away and parts of the upper and lower cross-head gibs shown in section and showing the improved oiling means borne by the gibs;
2 is a vertical transverse section taken approximately on the line II-II of Fig. 1.
Fig. 3 is a fragmentary plan View of the intermediate portion of the upper cross-head gib taken in the direction of the arrow 3 in Fig. 1.
Fig. 4 is a fragmentary inverted View of the intermediate portion of the lower gib taken in the direction of the arrow 4 in Fig.
Referring by numerals to the accompanying drawings 1 and 2 designate upper and lower cross-head guides respectively and between which is disposed the cross-head 3 having the upper arranged crosshead gib 4 which slidingly engages the guide 1 and the lower arranged cross-head gib 5 which slidingly engages the guide 2. The cross-head gibs 1 and 5and a pair of intermediately disposed portions 6 which are secured to the gibs 4.- and 5 by the bolts 7 comprise the cross-head to which the piston rod 8 and connecting rod 9 are secured.
Formed in the upper cross-head gib l interniediateof its ends is an oil chamber 10, and iocated on the bottom. 11 of said chamher is a coil spring 12, and seated on the 7 roller 16, said roller normally engaging the undersurfac'e 17 of the guide 1.
111 the reciprocatory movement of the cross-head between the guides, 1 and 2, the roller 16 having contact with the tindersurface 17 of the guide 1 Will be revolved and as said roller is located in a body of oil con tained in the chamber 10, the periphery'of said roller will roll an oil layer onto the surface 17, thereby lubricating said surface and inasmuch as the gib 4; bears against the guide 1, the wearing surface of the gib will also be lubricated. The spring 12 will resilientiy hold the periphery of the roller 16 in oiling contact with the undersurface 17. For supplying oil into the chamber 10, an oil-hole 18 is provided.
Formed in the lower cross-head 5 intermediate of its ends is a chamber 19 which is open at its lower end and located in said chamber is a horizontally disposed perforated plate 20 having oppositely disposed upturned portions 21 which bear against re spective walls 22 of the chamber, and located on said plate is wadding of absorbent material 23 for the absorption of oil which is filledinto the chamber through the oil opening 2%.
In the operation of the cross-head relative to the lower gib 5 thereof, the plate 20 which is loosely mounted in the chamber 19 will normally bear against the upper surface 25 of the guide 2, the absorbent material such as waste permitting a sufficient amount of oil to escape through the apertures of the plate onto the surface 25 of the guide 2.
What I claim is 1. In a crosshead, a gib therefor, a guiding element for said gib, said gib having an oil chamber opening onto the surface of said element, alubricating roller rotatably engaging said guiding element, a support for said roller, said support having its base portion slidably engaging the sides of said chamber for maintaining said roller in a vertical position, resilient means located in said chamber constantly urging said roller into contact with said guiding element, and
