To (4Z5 whom, it may concern.-

Be it known that I, EDGAR WYVILL SNE- DEKER, a citizen of the United States, residing at Jamesburg, in the county of Middlesex and State of New Jersey, have invented a new and useful Improvement in Combined Sawing, Molding, and Turning Machines, of which the following is a specification.

My invention relates to a combined sawing, molding, and turning machine for woodworkers use; and it consists of the peculiar combinations and adaptations of devices and in the novel construction and arrangement ofth e various parts of the same, substantially as hereinafter fully described, and particularly pointed out in the claims.

The object of my invention is to provide a single machine with several independent mechanisms or devices for carrying on the various operations of sawing, molding, turning, and finishing wood, and for performing certain other necessary work in a shop or other place,which mechanisms can be very readily thrown into and out of use in a minimum of time and perform their necessary work without interfering with one another.

In the accompanying drawings, which illustrate a machine embodying my invention, Figure l is a top plan view. Fig. 2 is an elevation taken from one side of the machine,and Fig. 3 is a like View from the opposite side of the machine. Fig. 4 is a front end elevation. Fig. 5 is a longitudinal sectional view on the line a; 00 of Fig. 1. Fig. 6 is a transverse vertical sectional view on the line y 1/ of Fig. 2. Figs. 7 and 7 are detached detail views of the removable sandpapering head. Fig. 8 is a side elevation of the removable turning-head, and Fig. 9 is an end view thereof. Fig. 10 is a detail View of the lever and mechanism which controls the pulleyofthe jig-saw. Figs. 1]. and 12 are detail views of parts of my improvements. Fig. 13 is a vertical sectional view taken longitudinally through the tubular shaft of the roundinghead.

Referring to the drawings, in which likelctters of reference denote corresponding parts in all the figures, A designates the main supportingframe of my improved combined machine, which comprises, essentially, the vertical uprights or legs a, the horizontal upper silIs,a a flat horizontal table, a, connected with the upper ends of the legs, and the horizontal beams a secured to the uprights near their lower ends, the whole being very securely united to provide a rigid and firm structure.

B designates the main driving-shaft of the machine,which is arranged in ahorizontal position near one end and in the lower portion of the main supportingframe A, the said shaft being journaled in suitable boxes or bearings, b, that are rigidly afiixed to two of the horizontal beams a of the frame A. lhis horizontal driving shaft carries two large pulleys, (l and D,which are rigidly affixed or connected thereto to rotate with the shaft and impart motion to the various other mechanisms or devices to perform different classes of work. One of these pulleys, O, is arranged within the side edges of the-horizontal table and immediately beneath the same, and the other pulley, D, is arranged at the opposite extremity of the shaft and exterior to the horizontal table of the frame.

I will now proceedto describe the peculiar arrangement of the several parts of the circular saw, which is to be driven from the pulley O.

E designates a swinging supporting-frame, which is arranged or disposed in an inclined position and is adjustably connected to the horizontal driving-shaft, as will be more fully described presently. This swinging frame comprises the parallel side bars or standards, 0, and the transverse connecting or tie bar 6', intermediate of the side bars, the ends of the transverse bar being rigidly affixed to the side bars to insure strength and stability to the frame. The lower ends of the side bars of the swinging frame are loosely connected to the horizontal driving shaft, and they are arranged on opposite sides of the large pulley O thereon, and the upper terminal ends of the said side bars carry suitable hearings or boxes, f, which are rigidly affixed or secured thereto. A horizontal saw shaft or mandrel, F, is journaled in these boxes or bearingsf of the frame E, and this shaft or mandrel is moved or ad justed with the frame so that it will describe an arc of a circle. The saw shaft or mandrel is arranged beneath the table a of the supporting-frame A of the machine, and the shaft or mandrel does not come in contact with the said table at the highest point of elevation or adjustment of the frame E, so that the shaft or mandrel is arranged below and concealed at all times by the horizontal table of the frame. One end,f', of the saw mandrel or shaft is extended beyond one of the side bars, 6, of the swinging frame E, and to this extended end f of themandrel or shaft is rigidly affixed a vertical circular saw, F, of

any approved pattern. The periphery of the saw is extended or projected through a transverse horizontal slot, in the horizontal table a of the main supporting-frame to adapt the saw toact upon work of different classes held on the table by means of a suitable gage, F,

which is of the common or any preferred class.

A horizontal draw-iron or adjusting-rod, F,

is loosely or pivotally connected at its inner end to the sawmandrel or shaft at a point thereon between the parallel side bars, 6, of the swinging frame E, and this draw-iron or adjusting-rod is extended beyond one side or edge of the table through a horizontal slot in one of the upper sills, a of the frame A, that is arranged beneath the table a. The outer terminal end of the draw-iron is provided with a; handle of any preferred form, so that the said draw-iron can be easily grasped by the attendant to move the same endwise or longitudinally, and thereby change or vary' the position of the swinging frame E, to raise or lower the same, and thus project the edge of the circular saw above or beneath the horizontal tablea, according to the direction in which the draw-iron and frame are moved.

' The draw-iron is held in; any desired position by means of a binding-screw, F*,-that works in a suitable threaded opening or hearing in the frame A, and the inner end of the said screw binds upon the draw-iron to prevent theilatter from moving, this screw being arranged at one side of and beneath the table, so as tobe within convenient reach ofthe operator and out of the way of the work upon the table.

The gage F is adjustable toward and away from the horizontal slot f of the tablea in suitable guides or ways, as is usual, and the said gage is adapted to be turned across the slot)" at right angles and at any other angle between its parallel position with the slot and its right-angled position thereto,according to the nature of the sawing to be performed by the circular saw.

To use the circular saw for ripping purposes, the draw-iron is withdrawn to itsfullest extent from the frame, so that the swinging frame is elevated to its highest point, after which the draw-iron is held'from retrograde movement by adjusting the binding screw 1*. The circular saw is thus projected or extended beyond the table,so as to properly act upon the work which is guided thereto by the gage F which is arranged parallel with vious; I

As a cut-off or c'rosscut saw, the gage is placed at a right or other angle desiredacross the slotf, as isobwith the slot h.

the slotf of the table, and the handle of the dI'ELW-il'OlllS grasped so that the said iron can be drawn toward the operator to adjust the frame and move the saw to the work as required, the binding-screw remaining out of contact with the draw-iron in this instance,so

that the draw-iron canbeeasily operated and controlled by the attendant. V For rabbeting purposes the draw -iron is moved until the desired heightof the saw above the table has been attained, and the bindingscrew is then tightened upon the iron to prevent it (the swinging frame) and the saw carried thereby from retrograde movement.

I The saw mandrel or shaft carries a small band-pulley, g, which is rigidly affixed thereto and arranged in line with the large band-pulley O, and the said large and small band-pulleys are connected by anintermediate belt, so that the saw mandrel or shaft is positively rotated by motion from the driving-shaft B of the machine.

The main driving-shaft of the machine rotates freely without hinderance from the swinging frame E, which is supported thereon, and the movements of the said frame E are independent of the rotary motion of the main driving-shafr. As the frame swings or moves backward and forward in the arc of a circle, the small band -pulley g preserves its distance from the driving-pulley G at all points of adjustment of the frame, and hence the intermediate band, g, is not slackened or otherwise affected by the movements ofthe frame, th ereby rotating the saw-mandrel at all times when this part of the machine is in use.

The end of the saw mandrel or shaft opposite to the extended end f thereof is projected or extended a short distance beyond one edge of the horizontal table a of the main frame and passes through a horizontal slot formed in one of the bars a of the main frame, (see Fig. 3,) and in this extended end of the shaft or mandrel is formed a rounded socket, f, that is adapted to receive a round end of a boringbit or other tool, G, which is clamped or held more firmly and securely in placeby means of a binding-screw, G, which works in a suitable threaded opening of the mandrel or shaft and impinges upon the bit or tool, as will bevery readily understood.

The work that is to be operated upon by the boring-bitorother tool is supported upon a supplemental table, H, that is arranged at one side of the main frame A, and this table is provided with-a vertical flange, h, which impinges upon the sides of two of the uprights or legs a to sustain the table in a horizontal position. The table is further provided with a depending arm, H, which is slotted longitudinally, as at h,'and through this slot of the arm passes a threaded bolt or screw, h which also passes through a similar slot that aligns This slot h is formed in a vertical piece or upright, H, that is rigidly affixed to the main supporting-frame, and the table H is thus adj ustabl y secured to the main frame of the machine, so that work can be held or supported thereon at different heights or elevations and at different positions.

The boring or drilling bit or tool G can he very easily removed by releasing the bindingscrew and pulling the tool from the mandrel and a rotary sandpapering-head, I, connected to the mandrel to be rotated therewith. This rotary head comprises a flat disk, which has a hollow boss or enlargement, i, on its rear side, in the cavity of which the end of the mandrel is fitted. The disk or head is rigidly held and clamped on the mandrel by a binding-screw, i, that works through a suitable threaded opening in the boss or enlargement of the head or disk, and the periphery or edge of the disk is inclined or beveled, as shown at 1?, so that a clamping or binding ring or annulus, 1, can be readily fitted thereon to clamp the sand or emery paper between the beveled periphery of the rotary disk or head and the ring or annulus. The said ring is beveled or tapered transversely, as shown, and in fitting the ring upon the head or disk the reduced edge of the ring is first fitted on the lower edge of the beveled disk, and the ring is then forced or pushed by hand upon the periphery of the disk to conceal the periphery of the latter and lie flush with the vertical faces of the same, thereby securely clamping the paper between the periphery of the disk and the ring. The outer vertical face of the rotary head or disk is thus covered by the sand-paper, and the work is supported on the table and pressed or forced by hand against the vertical covered face of the rotary head or disk, in order to smooth and finish the work, as will be very readily understood.

It will be seen that the rotary finishinghead can be readily detached and connected to the saw mandrel, and the sand paper thereon can be renewed with ease by merely detaching the ring or annulus.

The main driving-shaft B of the machine is driven or operated by a treadle, J, which is arranged transversely of the machine at one side, and this treadle is ri idly affixed to and carried by oscillating side pieces, J, which are arranged parallel with each other upon opposite sides of the machine. The free ends of these side pieces, J, of the treadle are pivoted upon two of the legs a of the main frame, and these side pieces can be operated by the foot of the attendant as well as the treadle J itself, thereby adapting the treadle to be operated from either side of the machine by the operator.

The end of the main driving-shaft B, at the end where the pulley O is connected thereto, is extended beyond the main frame A of the machine and has a crank-disk, j, rigidly affixed or connected thereto. This crank-disk has a crank-pin, j, to which is connected the upper end of a link, J the opposite end of which is connected to one of the side pieces of the treadle at an intermediate point of the length thereof. The opposite side piece of the treadle is connected with the crankshaft by a similar link, J", which is pivoted to the treadle and likewise connected to a erankpin, 9' that is rigidly affixed to one of the radial arms of the large pulley D of the shaft. It will thus be seen that the treadle extends around three sides of the machine, so that it can be operated by the attendant standing on either side thereof, and both sides of the treadle are connected to the drivingshaft to insure a steady motion to the same. The driving-shaft can thus be driven by thepower of the foot applied thereto through the treadle and the intermediate connections, and I have also devised means whereby the said shaft can be driven or rotated by hand, which I will now proceed to describe.

A couutershaft, K, is journaled in fixed bearings k at the upper portion of the main frame A,beneath the horizontal table thereof. This shaft is arranged on the opposite side of the main frame to the saw mandrel or shaft and its frame and in the upper part of the J main frame, and to the shaft is rigidly affixed a sprocket-wheel, it, over which a continuous sprocket-chain, it, passes, a similar sprocketwheel, It", being rigidly affixed to the main driving-shaft Bof the machine. The sprocketchain encompasses these sproeket-wheels on the main and counter shafts to communicate the motion of one shaft to the other, the counter shaft being rotated by a' suitable crank-handle, K, that is connected thereto and arranged at one side of the machine, so as to be turned by a person. One end of the counter-shaft is extended flush with the side of the machine where the supplemental adj ustable table H is located, and the said extended end of the shaft has a socket formed therein, in which a pin or arm on the crank-handle is fitted'to securely connect the said parts together, while permitting them to be readily disconnected.

I will now proceed to describe my improved band-sawing mechanism in the peculiar arrangement and adaptation of its parts.

L designates a vertically-disposed arm or standard which is rigidly affixed to one side of the horizontal table a of the machine, at the side thereof where the band-pulley D is located. This arm is bent or curved forward, as shown, and bifurcated to provide the separate arms Z, through which vertical aligned openings are formed for the passage of a vertically adjustable rod, m. This rod passes through the aligned openings in the standard, and is held at any desired elevation by means of a binding-screw, m, which works in a suitable opening in one of the arms and bears upon the rod, and to the lower end of the rod is rigidly affixed a guide, M,which is adjustable with the rod, and 1s thereby adapted to beheld at different points above the horizontal table a of the main frame A. A large belt-pulley, N, of substantially the same diameter as the belt-pulley D, is loosely journaled on a suitable shaft, 01, that is affixed to the standard L at a suitable point thereon, and this pulley is arranged above the pulley D and in the same vertical plane, so that a saw-band, N, can pass over the said pulleys, the pulley D serving as the driving-pulley and the pulley N as an idler-pulley. The saw-band also passes over a tightening-pulley, O, which is journaled in the upper end ofa supporting-arm, 0,which is connected at its lower end to one of the uprights of the main frame, and this pulley and its supportiugarm are arranged at one side of the table and in the same vertical plane as the band-pulleys D N, so that the saw-band can pass freely over the same; This pulley is adjustable toward and away from the bandpnlleys D N, so that the tension on the band can be taken up and slackened by means of a regu lating-screw, O, which works in a suitable aperture in the main frame of the machine. This regulating screw also works in a suitable threaded nut, 0, on the arm 0 to adjust the latter, and the inner end of the opening in the main frame is filled by an elastic packing, 0 against which the inner end of the screw bears for the purpose of taking up the expansion and contraction of the saw-blade.

It will be seen that the band-saw'cau be very readily placed over the band-pulleys D N l yadjustiug the tightening-pulley 0 toward the bandpulleys, after which the regulatingscrew is turned to adjust the tightening-pulley away from the band pulleys, and thereby tighten the saw-band. When the drivingshaft is rotated, either by power from the t-readle or thecounter-shaft, the driving pulley D causes the band to move and pass over the idler and tightener pulleys, and the guide M can be readily adjusted, as required. The screw can be turned to regulate the tension on the saw-band, and the latter can be readily displaced when it is not desired to use the same. WVhen the bandsaw is employed, aremovable table, 0 is connected by locking de-- vices with the horizontal table a of the main frame A, as shown in Fig. 1 of the drawings in solid lines. This table supports the work that is operated upon by the band-saw, audit is arranged at one side of the table a and in substantially the same plane.

I will now describe the jig-saw mechanism, in which I employ a rock-shafn-P, which is arranged in a horizontal position at the lower portion of the main frame, at the end thereof opposite to the main driving-shaft. This rockshaft is journaled in suitable boxes or bearings, 1), that are rigidly affixed to the horizontal sills a of the main frame A; and to opposite ends of this rock-shaft are connected arms 19 19 which are rigidly affixed to the shaft and extend therefrom in opposite directions. One of these arms, 1), is pivotally connected to the lower end of a link, 17 which is-likewise connected at its upper end to a crank-pin, q, rigidly affixed to one end of a crank-arm, Q. This crank-arm is rigidly affixed to and rotates with a shaft, R, which is journaled in suitable openings orbearings which are formed in or secured to a swinging hand-lever, R, which is arranged in a horizontal position at one end of the main frame. The swinging lever is supported on a friction-bolt, r, at an intermediate point of its length, and the lever is capable of movement on the bolt under the pressure of the operators hand thereon, the lever being held against movement by the frictional contact of the bolt with the walls of.

the opening in the lever, through which the bolt is passed. The boltis suitably affixed and supported in the upright of the main supporting-frame, and it provides a pivot for the lever, one end of the latter being extended beyond the horizontal table of the frame, so that it can be conveniently grasped and adjusted by the attendant, and the other end of the lever being extended beneath the table. This inner end of the lever is provided with a short horizontal arm, 1", which is arranged parallel therewith and a short distance from the space, and thereby provides an intermediate space, in which the band-pulley r is lo- 'cated, this arm 1' being connected with the lever by a shorttransverse arm, 'r, the said arms and lever being rigidly and firmly secured together or formed-of a single piece. The shaft R is journaled in suitable openings or bearings near theinner end ofthe leverand the short-arm r thereof, and the pulleyr -is rigidly affixed or secured to the shaft, so as to rotate the same by motion from the large pulley D, which is transmitted by an intermediate belt, 1", that encompasses the pulleys D r",

the crank-arm being rotated with the pulley and its shaft to reciprocate the rock-shaft P. The swinging hand-lever is pivoted eccentric to the aXis of the large pulley D, so that the pulley r carried thereby is caused to lie at different distances from the said pulley as, for instance, when the lever is elevated, as shown in full lines in Figs. 2 and 4 of the drawings, the. pulley carried thereby lies nearer to the pulley D, and when it is lowered the said pulley 1 lies farther from the large pulley D. It will be seen that when the lever and pulley are elevated the band 1'" will be tightened, so that it will transmit the motion from the pulleyD to'the pulley r", and when the lever and small pulley carried thereby are lowered the band or belt will be slackeued, and it will not transmit the motion is arranged above the horizontal table of the main frame A'and the other beneath the same, and the rear ends of the bars are independently pivoted to opposite ends of a fixed vertical post or standard, T. These pivots of the bars are each formed by a pair of coniealpointed regulating-screws, which work in suitable aligned openings formed in the extremities of the fixed post, and the pointed ends of the screws bear against the bars at diametrically-opposite points on the same. This post or standard is arranged at one side of the horizontal table a of the machine, and it is rigidly affixed or connected to a bracket-lng,t, of the said table. The post is made in two sections, which are beveled at their meeting ends to form alapjoint, and the said sections are further connected by adowel-pin, t, which enters the meeting ends of the sections. The lower bar, 8, of the jig-saw frame is connected to the lower end of the lower section of the post, which is rigidly affixed to the bracketlug of the table, and the upper bar of the said frame is pivotally connected to the upper section of the post, which is detaehably connected to the lower fixed section of the post. The rear terminal ends of the bars 8 and s of the jig-saw frame are connected together by an intermediate swivel, T, whereby the tension or force exerted by the bars on the saw-blade can be regulated, the said blade being securely affixed by any preferable means in the opposite inner ends of the parallel bars 8 and s of the frame and working through a vertical opening in the horizontal table a of the main frame. The blade of the jig-saw as arranged is in proximity to an adjustable gage, T, on the table a, this gage being similar in construction to the gage F and operating in like manner. The saw-frame is reciproeated by a link, V, which is connected to the arm 10 of the rockshaft and the lower bar, 3, of the frame. Vhen the band 1 encompasses the pulleys D and r", the shaft R is rotated, and the motion thereof is converted and transmitted to the rockshaft P by the intermediate connections, and the motion of the rock-shaft is communicated to the jig-saw frame S by the link t the bars of the said frame S being pivoted to permit of the vertical play or reciprocating movements of the inner cnd of the frame and the saw-blade therein. The upper bar, 8, and the blade of the frame S can be readily detached from the machine, when it is desired to use or employ any other part of the machine, by first disconnecting the swivel and blade and then releasing the upper section of the post or standard from the dowelpin. The belt or band is removed from the pulleys D r", and the lower bar, s,of the frame being beneath the table of the main frame other work can be performed or carried on upon the same by the other mechanisms without hinderance from the jig-sawing mechanism.

I also provide a forming or molding mechanism for shaping stock to any preferred configuration, as in making molding strips or the like. I employ a vertically-sliding frame, U, which is arranged near one side of the main frame A, so that ready access can be had thereto to adjust it by hand, said frame having its vertical sides fitted in vertical aligned guides formed in the opposing edges of parallel vertical guide-bars U, which are arranged at a suitable distance apart and rigidly secured to the main frame A. The cross or transverse bars of the sliding frame have suitable aligned openings or bearings, in which is journaled the shaft U of a vertical pulley, U, which is capable of rotation in a horizontal plane and is driven by intermediate belt -connections from the main driving-shaft B. The upper end of the shaft of the pulley is extended or projected above the frame, and its upper extremity is threaded, as seen in Fig. 6, and on this extended end of the shaft is fitted a tubular sleeve, U, which holds the fixed cutters or knives U in place, said cutters being extended or projected above the sleeve. These cutters are curved or shaped to the desired configuration to properly cut out the stock, and the sleeve and its cutters are held in position by means of a nut which is fitted on the upper threaded end of the rotary shaft. The sliding frame, together with the shaft and the pulley for rotating thelatter, is adapted to be moved vertically in the fixed guides. so that the cutters or knives on the shaft will be extended above the table of the main frame to adapt the cutters to properly act upon the stock which is placed on the table and ad justed in proper relation to the cutters,which pass through an opening formed in the table, as shown in Fig. 6 of the drawings. The sliding frame is held in its elevated position while the cutters are at work by means of abindingscrew, U which works in a suitable threaded opening formed in one of the vertical fixed guides U and impinges against one of the sides of the frame. The belt which drives the pulley slips over the same or is moved therewith when the frame is moved upwardly to adjust the cutters for operation. The sliding frame is lowered and the. cutters on the shaft thereof are drawn beneath the table when it is desired to use the machine for other purposes than forming moldings, and the molding mechanism is thus entirely out of the way, so as not to interfere with the other parts of the machine.

V designates a horizontal shaft which is arranged above the main driving shaft and in rear of the same, and this shaft is journalcd in suitable bearings that are rigidly affixed in the main frame A. The shaft carries a bandwheel, 1;, which is belted to the large drivingpulley D, to be driven by the driving-shaft, and it carries another pulley, V, which is belted to the pulley U by a belt, V", so that the former is positively driven or rotated by mot-ion from the driving-shaft. The former is capable of a vertical movement without hinderance from the belt V and it is adapted to be rotated by the belt at any height or point of elevation.

I will now proceed to describe my improved meehanismfor rounding square or angular rods. I employ a rotary head, WV, which is provided with a central opening or aperture, 10 and an integral concentric enlargement,

' the horizontal bars a ofthe frame.

a era-19s w, on its rear side, the central opening of the head being extended through the enlargement. This head is carried by a rotary hollow shaft, V,which is arranged in one corner of the main frame of themachine,beneath the table thereof, and in a plane above the upper edge of one of This shaft is journaled in suitable bearings, which areaffixed to one of the bars a of the frame, and it is arranged parallel with and in close proximit-y to the counter-shaft. The rotary tubular shaft carries a fixed belt'pulley, 5, which is driven by motion from the driving-pulley G, the treadle being used to rotate the drivingshaft in this instance. A binding-screw, 20, works in 'a suitable threaded opening in the enlargement to, and bears upon the periphery of the tubular shaft to securely connect the head thereto, so that it will rotate therewith, and in its outer face the head is provided with a chamber. or recess, :0 which is made circular in form and arranged eccentrically with .the axis of the head or disk. A rotary indicating-disk, W, of a diameter equal to or slightlyless than that ofthe chamber,is.loosely fitted therein, so as to lie flush with the outer l side thereof, and the disk is pivoted eccentrically to the rotary head, as shown, so as to be justed position by a binding-nut,'X.

capable of rotary motion therein independently of any movement of the head. The indicating-disk is thusarranged at one side of the center of the head, and it has a series of circular apertures or openings, 10 the centers of which are arranged equidistant at. or near the periphery of the disk, the centers of said apertures being equidistant from each other and from the center of the disk, as shown. These openings or apertures are of different diameters or sizes, so that they will accommodate work of requisite diameter, and the apertures are adapted to align or coincide with the central opening or passage in the head and its tubular shaft, as is obvious, whereby work fed to ,the indicating-disk will pass through the opening therein and the shaft andhead. The dial, after it has been adjusted, is'heldin position by a binding-screw, w, and the head has a fixed radial support,X, on its outer face, against which a cutter or. knife, Z, bears, This guide is provided with a longitudinal slot, 00, through which a threaded bolt or screw, a2, is passed, and which is connected to the blade Z, said screw being held in its ad- The outer face of the guide X is inclined transversely, as shown in' Fig. 8, and the longitudinally-movable cutter partakes of or assumes this inclined position. The cutter is adapted to be adjusted on the guide or support X toward the center of the head, so that it will act upon work of different diameters.

The indicating-disk is adjusted or turned so that the opening therein, of a diameter corresponding to that of the work to be operated upon, is in alignment with the central opening in the head and the passage of the tubular shaft, after which the disk is secured in position by means of the binding-nut hereinbefore described. A rod or barof wood is now fitted in the proper openings in the disk and head and passed into the tubular shaft, and the.

cutter or blade is properly adjusted to the work, and power is then applied to the shaft to rotate it and the head and cause the cutter to act on and turn the bar, which is fed or moved by hand through the tubular shaft and emerges from the opposite side of the machine in a finished state.

It will be understood that bars of different sizes can be readily turned, and that the parts can be easily and quickly adjusted for use.

The operation of my invention will be very readily understood from the foregoing description, taken in connection with the accompanying drawings.

The horizontal table a of the main frame has a movable section, 3, at the side thereof immediately above the saw-mandrel, as shown very clearly in Figs. 1, 3, 4, and 6, and the outer edge of this section 3 of the table is hinged to the frame, so that the hinged section can be elevated to expose the saw-mandrel beneath the table.

An emery-wheel of any approved pattern is adapted to be rigidly affixed to the extended endf of the mandrel or shaft,after the rotary saw has been removed therefrom,to adapt work of different character than that performed by any of the hereinbefore-mentioned devices to be'performed by the machine, the circular saw being readily and easily removed therefrom for the purpose of replacing it with the emery- Wheel.

It will thus be seen that I provide an im proved machine of simple and durable construction with independent mechanisms or devices which will perform the various kinds of work necessary in a shop or other place without interfering with one another, and that the machine can be run by either foot, hand,'or

steam power, it only being necessary, in the latter instance, to gear the driving-shaft B of the machine with an engine or other suitable motor.

I do not desire to confine myself to the exact details of construction and form and proportion of parts herein shown and described as an embodiment of my invention, as I am aware that changes therein can be made without departing from the spirit of my invention. The belt which encompasses the sprocketwheels or pulley on the main driving and counter shafts can be readily detached and placed over the pulley-G on the driving-shaft and the pulley r on the shaft R of the jig-sawing mechanism, thereby effecting the saving ofone belt. Of course it will be understood that the belt of one mechanism is removed and another substituted therefor when the different mechanisms are to be employed.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination of asuitable frame, a

vertical fixed standard arranged at one side of the frame, a driving-shaft carrying at one end a driving-pulley, an idler-pulleyjournaled on the standard and arranged in the vertical plane of the driving-pulley, an adjustable arm, 0, pivoted at one end to the frame, between and at one side of the driving and idler pulleys, and adapted to swing in a vertical plane and having a threaded bearing, 0, a tighteningpulley journaled on the said arm and adapted to ride upon the saw-band passing around the driving and idler pulleys, and a screw working in the threaded bearing of the arm and swiveled to the frame to adjust the arm and the tightening-pulley, as and for the purpose described.

2. The combination of the main frame, the drivingshaft, the rotating shaft R, belted to the drivingshaft and having a crank, the rock shaft P, journaled below the shaft R, the rod 2 pivoted to the crank of the shaft R and connected to the rock-shaft, the standard T, made in two sections having their meeting ends beveled and lap-jointed and united by the dowelpin 15, the bars S and S, fulcrumed at the ends ofthe standard, the swivel connecting the outer ends of the bars together, the lug or bracket connecting one section of the standard to the main frame, and the rod t pivoted to the bar S and connected to the rock-shaft, substantially as described.

3. The combination of a main carrying frame, a driving-shaft, asaw-framehaving the frames thereof supported on independent pivots, a rock-shaft, connections intermediate of the rock-shaft-andsaw-frame, aswinging handlever pivoted eccentrically to the axis of the driving-shaft, the connected pulleys carried by the drivingshaft and the swinging handlever, a crank rotated by the pulley on the swinging lever, and a pitman intermediate of the crank and the rock-shaft, substantially as described, for the purpose set forth.

4. The combination of a frame, thedrivingshaft, the saw-frame comprising the pivoted bars connected at one end by an intermediate lap-joint and dowel-pin, a rock-shaft connected to the saw-frame, and a shaft belted to the driving-shaft and connected with the rockshaft, substantially as described.

5. A turning-head having a central opening, an adjustable cutter,and an operated disk pivoted to the head and adapted to be turned to adjust one of the several openings thereof in line with the central opening in the head, as and for the purpose described.

6. A turning-head having acentral opening, a rotatable indicating-disk fitted within a recess in the head and having a series of apertures of varying diameters adapted to be adjusted in alignment with the central opening of the head, and a cutter, as and for the purpose described.

7. A turning-head comprising a disk having a central opening and a recess or chamber on one side thereof, a pivoted indicating-disk housed within the recess and having a series of apertures of diameters the centers of which are arranged equidistant from each other and from the'center of the disk, and an adjustable cutter, as and for the purpose described.

8. A turning-head having a central opening, an apertured indicating-disk, a fixed guide, and a longitudinally-adj ustable cutter bearing upon the guide, as and for the purpose described.

9. Aturning-head having a central opening, an apertured indicating-disk housed within a recess in the head, a fixed radial guide having the inclined outer face, and a longitudinallymovable cutter, as and for the purpose described.

10. The combination of the standard or part T, made in two sections, having their meeting ends beveled and lap-j ointed together and united by the dowel-pin t, the bars S and S, fulcrumed at the ends of the said part or standard, the swivel connecting the outer ends of the said bars together, the main frame, and the lug or bracket connecting one section of the part or standard to the main frame, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
