RALPH W. GORDON, OF RAPID CITY, SOUTH DAKOTA.
SCRAPING BLADE FOR BEARINGS.
Application filed September 18, 1924. Serial No. 738,442.
Scraping Blades for Bearings, of which the following is a specification.
This invention relates to a scraping blade for bearings.
An object of the invention is the provision of a scraper which is particularly adapt-ed for scraping and truing up bearings now commonly employed in connection with motors.
It is also a further object ofthe invention to provide a knife or scraper having a cutting edge so formed that only a portion its cutting edge will initially engage with the bearing surface being scraped and thus permit an easier manipulation of the blade with greater efiiciency.
This invention will be best understood from a consideration of the following detailed description in view of the accon1panying drawing forming a part of this specitis cation; nevertheless, it is to be understood. that the invention is not confined to the disclosure, being susceptible of changes or modifications, but such changes or modifications shall mark no material departure from the salient features of the invention as expressed in the appended claims.
Figure 1 is a view in perspective of the perferred form of my invention,
Figure 2 is a side elevation of same with a portion in section and illustrating the blade being applied to a bearing surface,
Figure 3 is a transverse section taken on the lines 33 of Figure 2,
Figure 4 is a transverse section taken along the lines 4.4l of Figure 2.
Referring to the drawings in detail, 10 indicates generally the body portion of the scraping blade which is of the cross section shown in Figures 3 and 4t and presents the convex surface 11 and a concave surface 12. The blade slightly tapers toward each of its ends from a central point thereof, and upon each end there is formed a triangular extension 13, said extension tapering-to a point at its outer end. Upon each extension 13 there is fitted a handle 14-, said handle having 'a' central longitudinal bore 15 which tapered toward its-outer end and adapted for frictionally receiving the extension 13. Also'each handle may be provided with a sleeve 16 at its inner end for reinforcing the same if so desired.
It will be observed that each edge of the scraper blade is slightly beveled as at 17 and that the bevel occurs in each instance at the tei-ininatingedge of the concave surface so that thesimilar edges of the convex surface terminate in a cutting edge.
In the use of the scraper the same is applied to a bearing surface 18 as illustrated in Figures 2 and a. It will be observed that the end portions of the cutting edge do not engage with the bearing surface. This permits the central portion of each edge of the blade to be. applied for scraping a small surface of the bearing which is being treated,
thus enabling any uneven surface of the bearing to be removed without scraping the remainder of the surface. It is found that this feature is very important in that when scraping bearings and truing them up the surfaces thereof need only be scraped in spots where an unevenness occurs.
What I claim is A. tool of the class an elongated blade concave-convcx in cross section and its longitudinal edges tapering from the longitudinal center of the blade toward each end thereof, said blade being bevelled. along the edges of the concave sur* face so that the corresponding edges of the convex surface terminates in a cutting edge, and a handle carried by each end of the blade.
