LOUIS S. ORITTENDEN, OF HORNELLSVILLE, NEW YORK, ASSIGNOR OF ONE- HALF TO CHARLES W. STEVENS, OF SAME PLACE.

WOODWORKlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 508,412, dated November 14, 1893.

Application filed March 16, 1893.

To all whom it may concern:

Be it known that I, LOUIS S. ORITTENDEN, a citizen of the United States, residing at Hornellsville, in the county of Steuben, State of New York, haveinvented certain new and useful Improvements in Woodworking-Tools, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in wood working tools of that class which are designed for boring,

vide a simple and cheap tool embodying an anger and a reamer whereby the hole may be bored and then byacont-inued use of the same tool the said hole may be reamed out as may be desired. I mount upon the shank of the auger a tapered block or casting which may be adjustable thereon and which is provided with a plurality of rasps which are preferably adjustably supported thereon. The block or casting may assume any desired shape in cross section and is formed with a cavity or chamber through which the shank of the auger passes, this being provided soas to avoid the necessity of shaping more than the hearing at each end thereof for the shank. The rasps may extend partially or wholly the length of the block or casting and may be held thereto in any suitable manner. The block or casting with its rasps may be removed from the shank when desired.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification and in. which-' Figure 1 is a side View of a portion of my improved combined auger and reamer. Fig. 2 is alongitudinal section through the reamer portion with the shank in place therein. Fig. 3 is a cross section through the reamer portion. Fig. 4 is a modification.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings t the shank.

Serial No. 466,329. (No model.)

by. letter, A designates an anger which may of, as seen in Figs. 2 and 3, and at opposite ends of this chamber or cavity it is bored for thepassage of the shank of the auger. The formation of this chamber lightens the casting, avoids the necessity of truing more than the end bearings for the shank, and the chamber may be used as a lubricant receptacle in which may be placed a little lubricant to prevent rusting or sticking of the casting upon This block or casting is secured to the shank preferably by means of screws 0 which are designed to be screwed through the casting as seen in Fig. 3 and bear upon the shank, the screws being formed with polygonal sockets c for the reception of a suitable implement for turning the same, the screw holes being formed in a longitudinally hollowed portion 19' of the casting as seen in Fig. 3 so as to permit of the heads of the screws being sunk below the periphery of the casting.

Around the periphery of the block or casting I arrange a plurality of longitudinallydisposed rasps D which are arranged in longitudinal grooves 01 in the casting as seen best in Fig. 3, the said rasps being held therein as by the screws E taking into holes in the casting as seen'in Figs. 2 and 3. These rasps may extendthe entire length of the casting as shown in Figs. 1 and 2 or they may be of less length than the casting as indicated in Fig. 4, and when thus of less length they may be adjustable lengthwise on the casting by forming the rasp with a longitudinal slot as shown at e in said Fig. at, the screw passing through said slot as indicated in said view.

In operation the hole is bored by the auger and then the continued revolution thereof brings the reamer into action. The reamer may be moved along on the shank of the auger any required distance to permit of the boring of the hole of the required depth. Any suitable form of rasp may be employed.

Modifications in detail may be resorted to Without departing from the spirit of the invention or sacrificing any of its advantages.

WVhat I claim as new is- 1. The combination with an anger, of a reamer adj ustably mounted on the shank thereof and provided with independent rasps, extending lengthwise thereof, as set forth.

2. The combination with an anger, of a reamer adjustably and removably mounted on the shank thereof and provided with adj ustable rasps, as set forth.

3. The combination with an anger and its shank, of a tapered casting adj ustably mounted on said shank and having an interior chamher and exterior rasps, as set forth.

4. The combination with the tapered casting having interior longitudinal chamber and shaft bearings at opposite ends thereof, of rasps seated detachably in longitudinal channels on the casting, substantially as specified.

5. The tapered casting having longitudinal channels and a longitudinal bore enlarged near its center, and a longitudinal exterior groove, combined with rasps seated in the channels, and securing means located in the said groove, as and for the purpose specified.

In testimony whereof I alfix my signature in presence of two witnesses.

LOUIS S. CRI'ITENDEN.
