IVIAIN-BEARING-CAP FACER.

Application filed June 16, 1924. Serial No. 720,440.

To all whom it may concern:

Be it known that I, HOMER O. PENOE, a citizen of the United States, residing at Spring Valley, in the county of Pierce and State of Wisconsin, have invented certain new and useful Improvements in Main- Bearing-Cap Facers, of which the following is a specification.

This invention appertains to tools and the primary object of the invention is to provide a novel tool for truing up the faces of bearing caps so as to insure the proper end thrust on the bearing caps.

Another object of the invention is to provide a novel tool which will positively true up the bearing faces of the cap with a minimum amount of time and with a minimum amount of labor.

A further object of the invention is to provide a main bearing cap facer embodying novel means for firmly holding the hearing cap in place on the tool, and the facing 'knife in engagement with the face of the bearing cap be trued, and novel means for operating the knife.

A still further object of the invention is to provide a main bearing cap facer of the above character, which will be durable and efficient in use, one that will be simple and easy to manufacture, and one which can be placed upon the market at a small cost.

WVith these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a side elevation of the improved tool,

Figure 2 is an end elevation of the tool,

Figure 3 is a longitudinal section through the tool,

Figure 4 is an end elevation of the tool showing the opposite end of the tool from that illustrated in Figure 2 of the drawings, the adjusting screw being shown in section,

Figure 5 is a plan view of the tool showing the bearing cap in place in dotted lines, and

Figure 6 is a transverse section through the tool taken on the line 66 of Figure 5 looking in the direction of the arrow and illustrating the cutting face of the knife.

Referring to the drawings in detail,

wherein similar reference characters desig nate corresponding parts throughout the several views, the letter A generally indicates the improved tool, which comprises a cylindrical body 10 on which the bearing capto be trued is adapted to be placed. One end of the cylindrical body 10 is provided with an annular stop flange 11 for engaging one end of the bearing cap, as will be hereinafter more fully described. Slidably and rotatably mounted within the cylindrical body 10 is a cylindrical shank or post 12 and the forward end of the shank is reduced in cross section as at 13 and protrudes forwardly from one end of the body 10. The reduced end 13 of the shank or post 12 has rigidly secured thereto in any desired way the head 14: which embodies a body portion 15 of substantially the same diameter as the body 10 and an annular flange 16 which is adapted to engage the opposite end of the bearing cap which is to be trued from that end engaged by the stop flange 11. The flange 16 of the head 14 is provided with a cut-out portion or notch 17 and the cutting knife 18 is fitted against one wall of the notch as clearly shown in Figures 2 and 6 of the drawings. The knife 18 can be held in place in any desired way such as by ma chine screws 19 or the like. The inner end of the knife 18 is provided with a beveled cutting face for engaging the face of the hearing which is to be trued, as will be hereinafter more fully described. The end of the shank or post 12 opposite to the end which has secured thereto the head 14 has formed or rigidly secured thereon the polygonal shaped block 20. This block 20 threadedly supports the adjusting screw 21 which is adapted to engage the stop flange 11 for moving the body 10 on the shank or post 12 toward the head 14. In order to facilitate the rotation of the adjusting screw 21 the outer end thereof can be provided with an operating crank handle 22 as clearly shown in Figure 1 of the drawings.

In use of the improved tool the adjusting screw 21 is threaded back out of engagement with the flange 11 after which the bearing cap 'is placed on the cylindrical body 10 with the face to be trued adjacent to the head 14. The tool and bearing cap are now placed in a vise or block and the screw 21 is adjusted so as to move the flange 11 into intimate contact with the bearing cap and so that the knife 18 will take a light out off of the cap. A wrench is now placed on the block 20 and the block and shank 12 are then rotated thereby. The rotation of the shank or post 12 of course rotates the head 1% and the knife 18 will give a smooth true face to the bearing cap. The position of the cap is now reversed so that the other end can be trued up.

When considerable metal must be removed from the bearing cap, extreme care must be taken not to take more metal of? of one end of the bearing cap then is taken oil of the other end.

With the use of the improved tool not only can a better bearing tace be obtained, but considerable time and labor is saved over the old method used by filing the ends of the bearing cap by hand.

Changes in details may be made without departing from the spirit or the scope oi this invention, but:

\Vhat I claim as new is:

1. A bearing cap facer comprising a hollow cylindrical body for receiving the bearing cap to be re-faeed, a stop flange formed on one end of the body, a head rotatably carried by the other end of the body, a refacing knife carried by the head, means for adjusting the head relative to the end of the cap to be re-faced, and means tor rotating said head.

2. A bearing cap re-t'acing tool comprising a hollow cylindrical body for receiving the cap to be re-faced, a stop flange formed on one end of the body, a rotatable head formed on the opposite end of the body, a post rotatably and slidably mounted within the body having one end thereof rigidly secured to the head, means for turning the shank, and means for adjusting the shank in the body, as and for the purpose specified.

3. A bearing cap re-tacing tool comprising a hollow cylindrical body on which the cap to be re-taced is adapted to be placed, a stop flange formed on one end ot the body for engaging one end of the cap, a head disposed at the other end of the body engaging the other end of the cap, a relacing knife carried by the head .and arranged to project inwardly toward the body, a cylindrical shank rotatably and slidably mounted within the body rigidly secured to the head, a block carried by one end of the shank "for facilitating the rotation of the shank, and an adjusting screw carried by the block arranged to engage the stop flange, as and for the purpose specified.

In testimony whereof I afiix my signature.

HOMER O. FENCE.
