BORING AND TENONING MACHINE.

SPECIFICATION forming part of Letters Patent No. 268,118, dated November 28, 1882,

I Application filed February 4, 1882. (No model.) I

To all whom it may concern:

Be it known that I, HENRY J. MILLER, of the town of Goshen, in the county of Orange and State of New York, have invented certain new and useful Improvements in Boring and Tenoning Machines for Carriage-Makers, of which the following is a specification.

Said invention consists in the combination and arrangement of ahorizontally-slidingdrills spindle in fixed bearings, which spindle carries the auger or tench-cutter, and has an adjusta ble shoulder to set its sliding motion, and is furnished with bevel-gears for rotary motion, and provided with an automatic feeding device, and also an adjustable spoke-holder, an adj ustable folly-clamp, and adjustable hub-clamp; and it consists, also, in the peculiar construction of the above parts, in combination with the whole, as hereinafter more fully specified.

In the drawings annexed, Figure 1 represents a side elevation of the machine constructed with my improvements. The spoke and hub clamps, the bench, and bearingsbf the drillspindle areshown bisected. Fig. 2 is a detached side view of the spokeolamp ot' the same. Fig. 3 is a top view of the hub-clamp of the same. Fig. 4 is a side elevation of the same, showing the felly-olamp in use and the bench and telly-clamp bisected. Fig.5 is a top view of the same. Fig. 6 is a detached crosssection of the telly-clamp. Fig. 7 is a detached cross-section of thehub-clamp. Fig. 8 is a detached perspective view of the adj listingwedges or wedge-slides.

A, Fig. 1, represents the working table or bench. Upon it are arranged the bearings B B, in which the horizontal sliding drill or boring-spindle O is rotated. Said spindle has on its forward end the drill-head provided with a set-screw to secure the auger D for boiin g, and when used for tenon-cutting the tenou-cutter E is secured in said head in place of the auger, and at the forward bearing, 13, is fitted, over said spindle a beveled pinion, F, which revolves in said hearing, but is held longitudinally to the same by means of a shoulder over each end of the bearing. The pinion F is furnished with a feather or key to engage in the groove 0, so as to cause the spindle to turn with the pinion, but allowing the spindle to slide freely through the same. The rotation of the pinion is caused by means of a beveled gear, G, which is furnished with a bearingstand, H, and a short shaft, to which a handcrank, L, is attached, so that by turning with the hand-crank the gear Grapid motion is imparted to the pinion F and the spindle 0.

Upon the rear end of the spindle is employed a fly-wheel, J, to obtain momentum and equal speed, and consequently facilitating the labor. On said fly-wheel is furnished a setscreW, X, to adjust the said wheel at the desired distance from the rear hearing, B, and thereby serve as a stop for the auger or tenoncutter, to stop it from cutting deeper than required. A short distance backward from the drill-head said spindle is furnished with a loose cross-head, K, which is held between two shoulders formed on the spindle, and allows the spindle to turn'loose therein.

L represents a vertical lever, which is pivoted to the lug or eyebolt M, secured to the bench, and said lever is slotted, so as to pass over the cross-head K, which has a trunnion on each side projecting into the lever to engage it, and thereby causing the sliding of the spindle, with the auger, from or toward the work with the lever L.

In order to cause the automatic feeding of the anger or tenon-tool, I employ the standard M, which carries one rope-pulley, N, in the top end, and one, N, near its lower end. A weight, 0, is attached to the bottom end of a rope, P, which passes over the pulleys N and N, and has its top end secured to the top end of the lever L. Consequently said weight draws the lever andspindle forward, and thereby feeds the auger or tenon-cntter until the fly wheel stops against the rear hearing, as afore-' said. To withdraw the anger or cutter, the operator presses the said lever back.

R represents the huh-clamp, S the spokeclamp, and T the folly-clamp, which are all arranged upon the bench which is provided with central longitudinal slots, U, to adjust them to the desired distance from the anger or tenontool, and each of them is furnished with a screw and tightening or thumb nut, V, under the bench to secure the clamp thereto while in use. The spoke-clamp S is constructed with a semicircular fork on its top end, in which the spoke is received. A semicircular bent hand-lever, s, is pivoted to the one prong of the clamp and drops over the spoke into the opposite prong, which is slitted open on its top end for the purpose. By pressing the lever 8 down the spoke is firmly clamped. Thelower part of this clamp is made with a vertical rod,

b, which is threaded from a distance above the' bench, and over the threaded end is fitted the adjusting-nut c, to form a shoulder for the clamp to rest upon the bench, so that by raising and lowering saidnut c the clamp is adjusted to the required height. On the bottom end is applied the thumb-nut V, to secure the clamp upon the bench. The hub-clamp B is. constructed with a base-block, W, which rests upon the bench, and has a bolt to pass through the slot U, and is furnished under the bench with the thumb nut V, to secure it firmly thereupon. A guide-pin, d, is also secured in the bottom of said base-block W, projecting into the slot U of the bench to guide said block in moving it properly. The top of said block has two upright opposite guide-posts, c 0, over which a top plate, f, is fitted, it having a central vertical stud or bolt. 9, by means of which the hubs of the wheels are secured. Said bolt has on its top end the thumb-nut h, and said top plate, f, has a slot for each of the guideposts 9 to pass readily through the same, and thereby guide the plate in its up-and down motion. Between the block and said plate I is employed a pair of wedge-slides, t' i, which are attached together, as shown in Fig. 8, and they are titted in grooves formed on the block, andtheplatefrestsuponthem. Consequently by sliding the wedge-slides it toward the anger the platef is raised, and moving the wedgeslides rearward said plate is lowered, so that by this means the hub-clamp is very readily adjusted to the proper height required, and by means ofthe slotin the bench the clamp is readily adjusted to the proper distance 'from the tcnon-cutter. A set-screw,j, is employed on the block to hold the wedge-slide firmly while cutting the tenon.

To hold the anger or tenon'cutter off from the work, I employ the ratchet 7c on the bottom end of the lever L, and a pawl, l, is pivoted to the bench, which pawl engages the ratchet and holds the lever until desired to liberate and allow the weight to feed the auger. The telly-clamp T is constructed similar to the hub-clamp. It has a base-plate,m, furnished with a holding-down bolt to pass in the slot of the bench, provided with a thumbnut, V, underneath. It has also a guide-pin in said slot. The base-plate is made with vertical guideposts a a, in which the table n is laterally guided while raised or lowered. Between this table and the base-plate m are employed the pair of wedge-slides t for adjusting the table to the desired height. The guide-posts a a have grooves to guide the wedge-slides i, and saidposts a, a are united on their top endswith a cross-piecep,to which the clamping-screw r is attached by means of a threaded plate y. The felly is clamped upon the table a, which is furnished with the adjustable guide-plates tt to locate the felly accurately in the proper direction for borin The plateg is slotted to adjust the clamping-screw proper for the telly.

Instead of using the hub with the set-screw a: formed on the fly-wheel J, a detached collar with a set-screw may be used as a stop to determine the sliding motion of the spindle C. When the tenons are to be cut all the spokes are inserted into their hub, which is held into the hub-clamp, and said fly-wheel J (or, if a detached collar is used, said collar) is so adjusted on the spindle O that the tenon-cutter accurately forms the shoulder of the tenon at the spoke, wherever the telly is to rest. By cutting the tenon of each spoke of the wheel and stopping with the said collarproperly,the shoulders of the tenonsare all made equidistant from the center of the hub of the wheel, and thus the follies, when placed, come to a true circle at once.. By means of the wedge-slides t 2', connected together and applied as shown, the table for cutting and boring the fellies is raised in vertical direction in a manner to retain a solid broad bearing. Fellies are very readily adjusted to the proper height, although having ditferent thickness. The relative distance of the telly from the drill is not altered in the clamp on accountofits thickness. The wedgeslides i t can be mark ed, so that they need only be placed to the mark and answer at once a number of fellies, and at any time secure the felly to its proper place without particular ex amination of adjustment.

1 do not claim any of the features alluded to in the Letters Patent granted to Reid and Pierce, No. 112,279, dated February 28, 1871.

WVhat I claim as my invention, and desire to secure by Letters Patent, is
