nrrovsnnsr 1N momes ros name TO ALL WHOM IT M AY CONCERN:

Be it known that I, HARRISON HAAG, of Bernville, Berks county, Iennsylvauia, have inventednu Improved Hub, Spoke, and Felice-Boring Machine; and I do hereby declare the followingtobe a`full, clear, and exact description of the same. Y Y My invention consists of certain adjustable mechanism, fully described hereafter, for boring the hubs, spokes, en d felloes of wheels, whereby much of the tedious manipulation' and measurement required for this class of work may bo avoided, and thevarious operations rapidly and correctly performed.

In order to enable 'others skilled iu the art to make and use myinventipn, I will now proceed to describe its construction and operation, reference being had-to the accompanying drawing, which forms n part of this specification, and in which- Figure 1, sheet 1, is a sectional elev-ationotmy machine as it appears when in use for boring the spokeholes -iu the sides offa' hub. v

Figure 2,sheet 1, n n end view ofthe same, and v Figure 3,'sheet l, a'plan view. -Figure 4, sheet 1, represents the machine cutting down and rounding the outer ends' ofthe spokes of a wheel. Figure 5, sheet 2, aplau view of the sume, land y i Figures 6 and?, sheet 2,' views of the .machine as it appears'wheu employed for boring the felices of va wheel.

Similar letters refer to similar parts througgghoutl the severaliri'ews'.

The framenf the machine consists of` two horizontal bars, .A and B, secured together vat right angles to each other, and supported at their outer ends', and at a suitable h eight from the ground, by legs a.l

'I Secured. to and projecting downwards from the bar A are two slotted rods,'C and Cf, connected together at their 'lower ends by a wedge-shaped block, b, the, inclined 'upper edge of -the latter serving as a rest for a wedge, b', which passes through the slots 'of therods C, and is maintained iuanydesired position with respect to the block b fby a pin, c, whichlis insertediuto on'eoi` a number of holes, c, of the'wedgo, (see fig. 2'.)

Owing to this arrangement of wedges, a block, e, which rests hpon the wedge b', may be raised or lowered to any required'extcnt, and upon this block is formed'a s'tep for the lower ond of a vertical spindle or rod, D,

whichpasses through -'thc bar A, and has at its upper end aldisk or circular gauge-plate, E.

Two uprights, F and F', pass through openings iu the barA, one on each `side of the gauge-plate E, and are secured -to the said bar by keys or otherwise, so that they maybe readily detached. A cross-piece,-G, connects and is arranged to slide readily upon these uprights, its upward motion being limited by pins f, iig. 2, and a plate, g, is so secured to the cross-pieco'that it shallproject over the top of the same, as shown-iu iig. 1. A screw-rod, H, provided with a suitable'handie', passes through a threaded opening in the plate g and through the cross-piece G, and is jointed at its lowerend, as shown.

The centres of the screw-rod H and of the gauge-plato E are. on the same vertical line, and extending around the latter, ncar'to its circumference, are three or incre rows of'holes hftheholes of each row being at an equal distance apart, and corresponding in number with' the number` of holes that are to be' bored in the hub ofa wheel, as will be hereafter described.

A rod, i, is -hinged to theupright, F, by a pin,'i', and itsY outer end is bent downwards,as shown in figs. 2 and 3, 'and arranged to 'enter any of the-holes'hof the gauge-plate that may be opposite to it, and thus prevent Athe latter Afrom turning.

In the bar B of the frame of the' machine is a longitudinal slot, j, through which projects the'lower end 'of a standard, I, and the latter maybe movedto 4anyposition in the said slot from or towards the bar A, and

-scured, ar'ter adjustment, by a key or wedge,j, passing through its lower end, and bearing against the und-er side of the har B. l

y A disk, J, is secured to the upright, I, by T-headed bolts, k k, which pass through curved slots, l, of the disk, and through a vertical-slot, l', of the upright, the bolts being provided at the rear of the upright with `thumb-nuts, m m. i

The tool It', operated by a suitable handle, q, passes through and isarranged to slidelongitudinally in bearings, pp, whiehare secured to the face of the disk J, and whatever may be the position of the latter in respect to the upright, I, the said tool always points towards a vertical line drawn from the vcentre of the gauge-plate E, (see iig. 3.) j

The machine, as above described, and as illustrated in the first three figures of the drawing,v is arranged for boring the spoke-holes in the hub of a wheel. The latterbefore being submitted to this first operation, is

y a mere solid block of worid, turned off on its exterior to the shape of a hub, as shown at, a: in fig. 1.

Before securing the hub to the machine, the wedge j is loosened, and the upright, I, and tool Ic are drawn back from the gauge-plate E. The hub is then placed upon the latter, resting on the pointed en'd of the spindle D, and upon points, r r, of the gauge-plate, and is pressed down upon the latter, and firmly secured by the screw-rod H, the lower pointed en'd of which bears upon the top of the hub, (see iig. 1.)

After thus securing the hub, the upright,.I, is moved towards the same, and fastened by means of its wedge Ig", the thumb-nuts 'm mqbeing thenA loosened, und. the disk J turned until the tool r'has been adjusted to'the angle at which it is desired to secure the spokes to the hub. This having been determined, theV thumbnuts m are tightened and the disk again secured, after which the end of the rod z' is inserted into ono of that row of holes in the gauge-plate equal in number with the number of holcswhich it is desired to bore in the hub.-

The tool lc is then operated by means of its handle g, and, at the same time, moved forward until a hole of sudicient depth has been bored in the hub, as shown in iig. 1. It is then withdrawn, and the tool 4z' is raised from the holo in the gauge-plate, after which the latter and the hub are turned until the end of the rod z' is opposite to the next hole, into which it is inserted. The tool is then opposite another point on the hub, and a second hole is bored, from which the tool is withdrawn, as before, and the hub is turned to a third position, determined by the rod z' and third hole in th'e gauge-plate, and this operation is repeated and continued until holes have been bored entirely around the hub.

By means of the above arrangement, tho required number ofA holes may be-bored in a hub at anyangle previously determined,'and at an equal distance apart. I

After boring the hub, it maybe readily withdrawn from the machine on raising the screw-rod H; and

A when a hub, longer or shorter than that shown, is to be bored, the gauge-plate E may be raised or lowered accordingly by means ofthe wedge 65, as before described, and the other parts ofv the machine adjusted to a p roper position. i l

In preparing the 'machine for cutting down and rounding the ends of the spokes, after they have been attached` to the hub, the standard I is moved back towards the rear end of thc bar B, as shown in iig. 4, and the uprights F and F', their cross-piece G, and the gauge-plate E and its spindle, are removed from the frame of the machine. Y

A rod, L, tig. 4, provided withv a disk, M, and having screw-threads at its upper end, to which is adapted l a handled nut, s, is introduced into the placeof the gauge-plate E and its spindle, the lowcr end of the rod resting upon the block e in the same manner as the latter. l

The hub X is passed over the rod, as shown in g. 4, and rests upon the disk M, to which it is heldby the handled'nut s, and the hub may be raised or lowered, as in the 'previous instance, by operating the wedge b', upon 'which the rod Ll rests. v Y v v l hollow auger, t, (such as is generally used for work of this kind,) is attachedA to the face of the disk J, in place of the tool represented in iig. 1, and the disk is properly adjusted, and the upright, I, moved towards the spokes, and secured before beginning the operation.

After thus securing the hub to the machine, it is slowly turned, and its spokes y are brought, one at a time, to a point opposite the cutting-tool, by which, as clearly shown/in figs. 4 and 5, they are successivelytreated, until all of them`have been properly. reduced and rounded at their outer ends.

'lhe wheel may be taken from the machine after removing the nuts, and another secured upon the rod, the several parts ofthe machine being adjusted, as before, to suit any size of wheel that is to be operated upon.

In order to bore the spoke-holes in the t'elloes of a wheel, the parts of the maehine are adjusted a third time. The standard I is moved back, the rod L and its disk are withdrawn, and the uprights F and F and their cross-piece G, are secured to the bar A, as at iirst. The cross-piece G is lowered until it rests upon shoulders u lu. of the uprights, iig. 6, and a. tool ofthe proper character is secured to the face ofthe disk J.

The felloos are {irst placed together in a circle, and marked in the usual manner at the points where they are to be bored for the spokes; they are then separated from each other, and bored in sections of one or more pieces, as I will now proceed to describe. l

'lwo arms, 'u v, are hung to the upper side ofthe cross-piece G by pins, v, in such a manner that their outer ends can be readily adjusted towards or from each other, and the said arms, after adjustment, are held by pins, 2v, fig. 7, which enter holes in the cross-piece and bear against the rear edges of the arms.

The felice Y, to be bored, rests upon the top ofthe cross-piece G, its rear convex edge bearing against the arms v, and it is held in this position while being bored by a` handled set-screw, z, which passes through a threaded opening in the plate g.

After boring a hole in the felloc, the pressure of the set-screw :z: is released, and the felloe, still bearing against the arms u, is turned to a proper position for boring a second hole, which operation is repeated until all the felloes of a wheel of one diameter have been bored; and all that is necessary, in order to bore the felloes for a wheel ot another diameter, is a proper adjustment of the arms v u.

sonia 3 It will he evident that the parts of the machine can be quickly and readily arranged to perform any of thc above operations, and that, by its use, much tedious manipulation and measuring will be avoided, and the work rapidly and correctly performed.

I I claim us my invention, and desire to secure by Letters Patent- 1. A disk, J, adjustable, as described, on n standard, I, and carrying a tool, k, to which both a longitudinal and a rotary motion may be imparted for the purpose set forth.

2. The cross-head G, with its arms v v', and screw-rods H and as, sliding on the vertical standards F F', so that when in an elevated position it will serve to retain a hub, and, whenl depressed, will hold a felloe,'all as and for the purpose specified.

In testimony wher eof,I have signed my nam'e to this specification, in the presence of two subscribing witnesses.

, HARRISON HAAG.
