Letters Patent No. 57,590, dated December 7, 1869.

IMPROVEMENT IN HOLLOW AUG-ER.

The Schedule referred to intheee Letters 'Patent and making part o'f the same.

To all whom it may concern: Be it known that we, H. T. BEAM, JOSEPH O. FREE- I MAN, and D. B. MILLS, of Palestine, iu the county of Crawford, and State of Illinois, have invented a new and usetul'lool for Making the 'Icnons `on Spokes and the Holes in Felloes for Wheels; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, in which- Figure 1 is a side elevation,

Figure?, an end View, and

Figure 3, a centr lvertical section, (taken in the line a: o: of fig. 2,) of the tool for making the tenons on the spokes; and

Figures 4 and 5 are side elevations making the mortises in the felloes.

Like letters designate like parts in all the figures.

The nature of our invention consists in the peculiar of the tool for construction of a tool for vmaking a `double tenon on spokes, as will be hereinafter described.

. 'Io enable those skilled in the art to make and use" our invention, we will proceed to describeits construe tion and operation.

In the drawing- A represents a cylindrical stock, with oblong openings in its side, and an extension', B,'on its lower end.

C is a ring inside of the stock A, and near its lower This is held in position by a small set-screw, a.

In thev under side of the extension B, isa groove, in which fits a bit or knife, D,wth two cutting-edges b and c, the form of which is shown-in fig. 6.

In the extension B is a slot,in which. is a bolt, d, which passes through the hitor knife D, by ineans of which it can be 'adjusted as described. v

.E is a cylindrical guide, which fits into an opening in the stock A, and is held in any desired position by means of a set-screw, e, which passes through the side of the'stock.

At the lower end of this guide isa flange f, which extends out against the inside of the cylindrical stock A.

Its upper end is formed to receivea brace or crank, bymeans -of which it is operated. p Inside of the guide E is a spindle, F, in the lower end of which is a centre-point formed like the end of a screw or gimlet.

On this spindle, a short distance from its lower end, is a flange, g, of thesaine diameter as the one ou the guide E, thus insuring the centre-point being kept in a line with the centre of the stock A.

On one ofthe side-piecesof the stock, is an extension, h,the lower edge of which does not extend quite down to the top of the lower end of the stock, thus forming a slot, fi.

In the flange g, of the spindle F, is a pin, j, ofthe proper size to pass into the slot i.

mortises in the felloes.

G is the stock, in the lower end of which is asocket for -the reception of the bit which -bores the hole through the felloe,which1nust be of the same size as the lower end of the stock.

The upper end of this stock is made of the proper form to receive the brace or crank, by means of which it is turned.

In a portion of the stock Gisa slot, 7c, across which, on one 'side of the stock, is a bit, l, the shank of which flush with the outside of saidvstock I A thumb-screw, on., which passes through the slot k, holds the bit in any desired position.

The bit l extends outside the stock, and a short distance above its cuttingredge is a projection, n, which prevents the bit from cutting too far into the felloe.

To form the tenon on point of the spindle F l turn it so that the pin j, in the flange g, `the slot c'. x

The stookA and its accompanying parts a're thenturned sueiently to drive the centre-point into the end of the spoke.-

When this has been done, give the stock A, aslight turn backward, which will release the' pin j from under the eztension h. Then turn the stock forward, and the spindle, F and its centre-point will be forced upward until the end of the spoke meets the cuttingedge bof the knife D,which will cut the first tenon on the spoke, as shown by the diagram marked A in the drawing.

This shoulder then meets'thc cutting-edge c of the the spoke, bring the centrewill pass into diagram marked .B in the drawing.

The depth of the second shoulder means. of 'the adjustable ring C.

To make the mortise in the felloe,a bit' is placed in the lower end of the stock G, which may be turned by an ordinary brace, and a hole bored entirely through the felloe.

The lower end of the stockG passes through until the bit l comes in contact' with the felloe, and cuts away the wood around the hole made by the first bit, the depth of the second tenon on the spoke thus forming a mortise of the proper form to receive the tenons on the end of the spoke.

is regulated by Figs. 4 and 5 are views of the tool for making the is flat and fits into a recess in the stock, its face being dolvn below the stock A, and
