To ALL WHOM ITMAY QONCERN:

Be it known that I, ALBERT BRUSH, 'ol' East Constable, in the county of Franklin, and State of New York, have invented a new and useful Improvement in Boring andlitting the Felloes and Spokes of aWheel; nndI do hereby declare that the following is o.l full, clear, and `exact.description thereof, which will enable others skilled in the art to inuke'end use the same, reference bei-ng hed tothe accompanying drawings, forming part of' this specification, in which-' t A Figure lrepresents a segment of o. wheel, showing a, spoke set in the felloe'according to my improvedphtn 0f boring and fitting. l

i Figure 2, n. view of the auger for boring the hole in the felloe of two diameters, forming two shoulders.

Figure3, o. view ofthe hollownuger for reuming the spokes to fit the holes iu thefclloes.

Figure 4, an end viewv of' the sume. l l

Similar letters of reference indicate like part-s.

This inventionv relates to un improved mode of boring the lelloes of a. wheel with h oles, the diameter of which isgreeter in one part than another,`and tting'the'. tenons ofthe spokes in the said holes bymaking them with a corresponding` hollow iuger. -By this plan greater strengthis secured to the wheel.,

lug. 1, A represents a felloe, and B e spoke ofa wagon-wheel. C is :in auger, formed 'with an ordinary screw-bit, a, :rt the end,'odupted in size for boring aiholeto receive the round *tenen b. On the uppcrport of thebitre placed-sharp lipprojections'or cutters c, opposite to each other, and about un eighthof en inch beyond the sides `oi the bit a, for the purpose ofcutting a. latrgerihole onthe inner side ofthe felloe, about threesixteenths of an inch in depth; The depth'of the larger hole bored by the c-utters'c is regulated-by an udjustable guards d, secured on'the side of the anger-shank with-a setscrew. l The tenon of the spoke B is mudefto lit thelhole thus bored inl thevfclloe A by a. hollow auger, D, which is provided with two setsI of -knives e e', for

cutting or reamingthe' end of the spoke in correspondence'with' the lergcr and smaller ports of thehole in the felloe. The u ei'- a'rt of the tenori cut with the hollow l(tuer has a. shoulder, s, which setsin the lor er .nrt

PP P e g P of the hole, while the cnd, b, fills the'smellcr part of the hole, in which itis wedged nsusun-l. 'lhis arrangement of the teuon in the -felloe gives greater strength und support to the parts respectively, end makes the wheel much stronger und more serviceable than when the tenon on the' spoke is ofon size from the inside to the 'outi side of the felloe.

Hoving described my invention, I claim as new, and desireto secure by Letters Patent- 1. The hollow auger D, provided with the knives e el', for formingupon spokes the tenons b an'd shoulderl s, ndapted to fit into the -recess in the felloes formed by the auger C, having the cxtended `cuttinglips c and adjustable guide d, constructed to operate uis herein shown und described.

2. The auger C, when provided withy the projecting cutting-lip c a-nd adjustable gauge d, constructed and operating 'as herein described, vfor. the pnrposespecied v ALBERT BRUSH. Witnesses:
