WILLIAM H. DUANE AND GEORGE W. BUGBEE, OF CINCINNATI, OHIO.
SPOKE TENONING AND TH ROATING MACHINE.
SPECIFICATION forming part of Letters Patent No. 276,009, dated April 17, 1883,
Application filed January 15, 1883.
To all whom it may concern:
Be it known that we, WILLIAM H. DOANE and GEORGE W. BUGBEE, citizens of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Spoke Tenoners and Throaters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention consists of a machine adapted to both tenon and throat spokes during one and the same passage, or to either tenon or throat them, at the pleasure of the user, by feeding such spokes by an endless articulated bed or other feeding mechanism through, between, or past suitable cutter-heads.
The novel features of construction and the novel combinations embodied in the machine are set forth in the claims at the close of this specification.
In order that the invention may be clearly understood, we have illustratedin the annexed drawings and will proceed to describe the best form of the combined machine at present known to us.
Figure 1 is a plan view of the machine. Figs. 2 and 2 illustrate a front elevation of the same. Fig. 3 is a side elevationthereof. Figs. 4 to 6 illustrate details of the machine.
The same letters of reference indicate identical parts in all the figures.
The main frame of the machine consists of a hollow column, A, constructed with suitable wings for the support respectively of the standard A, on which the slides of the tenoning cutter-heads are mounted, and the housings A of the articulated endless traveling bed. The front face of standard A is provided with parallel vertical ways, on which the slides B and O are fitted. These slides are connected by a screw, 0, which is swiveled to one and engages a nut on the other, so that by turning the screw by the handwheel C secured thereto, the slide provided with the nut may be adjusted with reference to the other slide. In this instance the lower slide, 0, is provided with the nut for screw 0 The upper slide, B, is also provided with a nut, which is engaged by a screw, B which extends upward and is swiveled to a bracket (No model.)
on standard A, carrying at its upper end a hand-wheel, B By turning screw B by its hand-wheel both slides B and C may be simultaneously adjusted. A horizontal shaft, B is journaled in suitable bearings of slide B, carrying at its inner end the upper tenoning cutter-head, B, and at its outer end apulley, B", by which it is driven. A similar horizontal shaft, 0 isjournaled in suitable bearings of slide 0, carrying at its inner end the lower tenoning cutter-head, G, and at its outer end a pulley, C by which it is driven. The tenoning cutter-heads may be ofany preferred construction, and armed with suitable cutters in the ordinary way. The pulleys B and 0 arranged in liue,'are driven by a single belt, E from a pulley, E, on the shaft E of the machine, in the manner clearly shown in Fig. 3, the belt being kept at proper tension under all adjustments of the slides B and O by a tightener-pulley, E journaled on a stud projecting laterally from the short arm of a lever, E", which is fulcrumed on standard A, and carries an adjustable weight on its long arm. 3
In order to prevent vibration and endwise movement of the spoke during its passage through between the tenoning cutter-heads, holders are provided, the lower one of which is unyielding and bears on the lower side of the spoke, while the upper one, which bears on the upper side of the spoke,-is yielding. These holders extend across the ends of the respective cutterheads in close proximity thereto, (see Figs. 1 and 2,) so that they will bear on the spoke close to the shoulder of the tenon to be'cut thereon. is a straight steel bar set up edgewise and firmly held in a groove in the top of a bracket, F, which projects from slide 0, to which it is so fitted as to be vertically adjustable thereon, in order that holder F may be set at the proper elevation with respect to cutterhead 0. The top edge of holder F projects a little above its supporting-yoke, and has a (lull edge, so that it may make a slight indentation Thelower holder, F,
in the spoke before reaching the cutter-heads and thus compel the spoke to continue its advance without endwise deviation. .The upper holder, G, is a fiat bar arranged edgewise in a slot in the lower edge of a yoke, G, which projects from slide B, and is so fitted thereto that it may be vertically adjusted thereon for suspending holder G at the proper height with respect to cutter-head B. Holder G is provided with vertical slots, through which pass pins secured in the yoke to prevent the falling of the holder from its seat in the yoke. Near each end of holder Ga pocket is formed above it in the yoke for the reception of aspiral or rubber spring, by means of which the holder is pressed downward to act with a yielding pressure on the top of the spoke. Thelength of the tenon to be cut is determined by the gage F fitted on the forward end bracket, F, and adjustable crosswise thereon.
The throating cutter-heads are located some little distance to the rear of the tenoning cutter-heads and project beyond the outer ends thereof. Thus a spoke may be fed by the same endless traveling bed from the tenoning cutter-heads to and through between the throatin g cutter-heads and throated at the proper point. The lower throatin g cutterhead, H, is arranged so far in advance of the upper one, I, that they may swing past each other far enough to throat the spoke to a sharp edge, if desired. The cutter-head 'H is fixed to theinner end of a shaft, H, journaled in suitable bearings of a hanger, H and carrying at its outer end a rim-pulley, H The hanger H is pivoted on a stud, h, projecting horizontally from the front side of a slide, H", gibbed to a vertical rail on an offset formed on the front side of the column A of the main frame. Slide H is provided with a nut which is engaged by the screw-threaded upper end of a downwardly-projecting screw swiveled to the main frame and provided at its lower end with a suitable hand-wheel for turning it. Gutter-head I is fixed to the inner end of a shaft, I,journaled in suitable bearings of a gaged by the screw-threaded lower end of a from pulleys on a counter-shaft, (not shown,)
but arranged in a plane about midway between the cutter-head shafts H and I. An-
other pulley on the same counter-shaft drives a pulley, E keyed to shaft E by a crossed belt,
E. The hanger H is so hung that its cutterhead has a constant tendency to move upward, while hanger l is so hung that its cutter-head has a constant tendency to' move downward, and the action of the belts H and 1" furthers these tendencies. The hangers may be pro vided with adjustable weights for convenience of balancing the downward pressure of one cutter-head by the upward pressure of the other. The respective frames of the hangers H and 1 are extended behind their cutterheads to reach beyond the outer ends thereof.
To each of these extensions a horizontally-adjustable bracket- (marked h and t", respectively) is fitted, projecting across the ends of the respective cutter heads H and I. To bracket h is secured a vertically-adjustable bar, h of horseshoe form, projecting upward from said bracket, and a similar verticallyadjustable bar, & is secured to bracket i, projecting downward therefrom. They act as directors, determining the lines of the cuts of the cutter-heads H and I by following the cross-sectional contourof every spoke fed past or across their closed curved ends.
In order that the tenoned end of the spoke may be supported during the action of the throatingcutter-heads,guidesKand K are provided behind the rear ends ofsaid cutter-heads, extending from near the tenoning cutter-heads to past the center of the throating cutter-head I. The lower guide, K, is fitted to slide in a horizontal guidewayin the top of the step of column A, and is adjusted by a screw, in directions parallel to the axis ofthe throating cutter-heads. The upper guide, K, is fitted in an uprightkneeof thelowerguide, andis adjusted vertically by a screw, k. By proper adj ustments by means of screws k and it these tenonguides may be adjusted to the length and thickness of the tenons.
The articulated endless traveling bed for feeding the spokes through the machine consists of a pair of endless chains, L L, and a series of cross-slats, L, secured to said endless chains, and provided with suitable fingers for holding the spokes. passed around flanged wheels on a shaft, L", at the front end of housing A, and around sprocket-wheels on a shaft, L at the rear end vof said housing. Shaft L isjournaled in fixed bearings, while shaft L is journaled in horizontallyadjustable bearings, by adjusting which the chains LLmay be properlystretch ed. Shaft L is driven at the proper speed by a train of spur-wheels from a shaft, M, which is in turn driven by a cone friction-clutch. The female cone, M, thereof, which is also a pulley, turns loosely on shaft M, and is driven by a belt from a pulley on the same counter-shaft which drives the throatingcutter-heads. The male cone, M thereof is feathered to shaft M, so that it may be slidthereon, and is constructed with a circular groove in its hub, which is engaged by the forked end ofa shifter-rod, M pivoted at its other end to lever M,
The endless chains are which is fulcrumed on the main frame, and
constructed with a handle which reaches to the front end of the traveling bed, where the operator stands in supplying it with spokes. The top edges of the sides of housing A form parallel horizontal rails for the support of the ends of slats L. At each end each slat L is provided with a pair of fingers, Z l, which project at right angles from the face of the slat, and are'formed on the reverse ends of arms fitted side by side in a dovetailed groove across the slat. In order that these fingers may be firmly held in place, and also readily adjusted with reference to each other as well as with reference to the slat, they are secured by crowding them against each other toward one edge of the dovetailed groove of the slat by a screw, 1 the tapering head of which may act directly on the beveled edge of one of the fingers, or which may operate a wedging cap, i as shown.
A presser-bar, N, is provided for holding the spokes down on the slats of the traveling bed. The shank of this presser-bar is curved, as shown in Fig.1, and fitted on a vertical dovetailed railon the side of colum n A, a screw, N, swiveled to a lug on said shank and screwing into a nut on the column, being employed to hold the presser-bar at any required elevation above the traveling bed. A deep groove is formed in the lower edge of this prcsser-bar for the accommodation of a series of yielding pressers, a, which are suspended at each end from pins fixed in the presser-bar and passing through vertical slots in the pressers n, Spiral or rubber springs are inserted in pockets of presser-bar above the presser, near their ends, which force the pressers with yielding pressure down upon the spokes. The adjacent ends of every two pressers are lap-jointed and their lower corners rounded. By virtue of these yielding pressers the presser-bar is enabled to hold down every individual spoke with equal force, since the pressers accommodate themselves to differences in the thickness of the spoke.
In the practical operation of this machine the spokes are fed crosswise in a straight line through between the cutter-heads. In order that the spokes may be tenoned as required to give the proper dish when driven into a wheelhub, they are fed lying at a slight slant on the traveling endless bed. This slant is determined by adjustment of the fingers l l at one end of slats L with reference to the fingers at the other end thereof. As each slat moves up around the flanged wheels of shaft L at the front end of the machine, the operator places a blank-spoke between the fingers thereof, taking care to run the end to be tenoned and throated up against the gage F Immediately afterward the spoke passes under presser-bar N and between holders F and G, the presserbar holding the spoke down from that time until it is discharged, after having been tenoned and throated. After a tenon has been cut on it, its tenoned end passes between the guides K and K, whereby this end is supported until the throating is finished. The tenoned and throated spokes, on falling from the fingers of the traveling bed at the rear end of themachine, may be received in a rack.
IVe believe that we are the first to produce a machine adapted to first tenon and then throat a spokeas it is being fed through the machine. In view of this fact we do not propose to confine ourselves primarily to the particular form of our invention illustrated and hereinbefore described in detail, the embodiment of the invention being capable of assumingforms in many respects quite different therefrom. For instance, instead of using a pair of tenoning cutter-heads and a pair of throating cutter-heads, only a single tenoning cutter-head and a single throating cutter-head may be employed, so as to operate on only one side of the spoke at the time. Other means than'an endless traveling bed and a presserbar may be used for feeding the spoke and holding it steady-as, for instance, a reciprocating carriage and presser-rollers.
Having thus described our invention, what we claim is-- 1. A machine for tenoning and throating spokes at a single pass, characterized by containing a tenoning cutterhead, a yielding throating cutter-head, which projects beyond the tenonin g cutter-head, and feed mechanism for conveying the spoke in the specified relation past the cutter-heads, substantially as before set forth.
2. The combination, substantially as before set forth, of a pair of tenoning cutter-heads, a pair of yielding throating cutter-heads, which project beyond the tenoning cutter-heads, and feed mechanism for conveying the spokes in the specified relation past the cutter-heads.

and the articulated endless traveling bed, having spoke-clamps, as described.
4. The combination, substantially as before set forth, of the yielding throating cutterheads, the articulated endless traveling bed, having spoke holders, as described, and a presser-bar over said bed.
