E. Q. ELLIOTT CROSSHEAD GUIDE Filed June 2, 1924 Patented Jan. 19, 1926.
UNITED STATES PATENT OFFICE.
EDWARD O. ELLIOTT, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE BALD- WIN LOOOMOTIVE WORKS, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.
CROSSHEAD GUIDE.
Application filed June 2, 1924. Serial No. 717,387.
To aZZ whom it may concern:
Be it known that I, EDWARD O. ELLIOTT, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Crosshead Guides,
' of which the following is a specification.
My invention relates to certain improvements in guides for the cross heads of engines, and, particularly, the guides of 1000- motive engines.
One object of the invention is to provide more eificient lubrication for the cross head, or other device, which is arranged to slide upon the guide. This object I attain by making the guide hollow and using the cavity as a reservoir for lubricant. This construction also materially lightens the cross head guide and keeps the contacting parts comparatively cool.
A further object of the invention is to improve the construction of a guide, in which side guide bars are used.
In the accompanying drawings:
Fig. 1 is a plan View of a cross head guide illustrating my improvements;
Fig. 2 is a side view of the guide;
Fig. 3 isa transverse sectional view on the line 33, Fig. 2; and
Fig. 4: is a sectional perspective view showing a portion of the guide.
Referring to the drawings, Figs. 1, 2, 3 and 4 illustrate a type of cross head having a body portion 1 with side guide bars 22, which are secured to the body by bolts 3.
These bolts may be tap bolts, or through bolts, as desired. The side guide bars are in the form of channels. The upper flange a of each side bar 2 extends over the body and takes the downward thrust. The lower flange 5 of each side bar extends under the body, as shown in Fig. 3. These flanges are spaced from the body 1 a sufficient distance to allow the cross head 6 to slide under the body. The cross head is shown by dotted lines in Figs. 2 and 3. In order to take up the wear on the lower flange of the side bars, shims may be placed between the upper flanges and the body, which is made hollow for the reception of any .suitable lubricant.
The cavities, 77 are open at the top and are closed by a cover plate 8, which is secured to the body by tap bolts 9. Small melts, or softens, the lubricating compound and causes it to flow through the small opening to the surface of the slide.
The guide is secured at one end to the back cylinder head 12 and at the opposite end to a knee 13, as shown in Fig. 2.
In some instances, the body portion of the cross head shown in Figs. 1 to i need not be made hollow.
It will be understood that my improved cross head guide, which is designed to carry lubricant for the wearing surface of the guide, may be modified to apply the invention to any of the ordinary types of cross head guides.
I claim:
1. The combination in a guide for a cross head, of a body portion having a longitudinal cavity open at the top and having a series of holes in the bottom communicating with the cavity; means for covering the opening; and a side guide bar secured to each side of the body portion, said side guide bars having upper and lower flanges, the upper flange of each side bar extending over the body portion, and the lower flange of each side bar extending under the body portion, and forming, with the body portion, a guide for a cross head.
2. The combination in a guide for a cross head, of a body portion having two longitudinal cavities open at the top and having a series of holes in the bottom communicating with the cavities; and a side guide bar secured to 'each side of the body portion, said side guide bars having upper and lower flanges, the upper flange of each side bar extending over the body portion, and the lower flange of each side bar extending under the body portion, and forming, with the body portion, a guide for a cross head.
EDWARD O. ELLIOTT.
