As shown in said drawings, A designates a drill-press of ordinary form provided with a vertically-arranged driving-spindle A, a

counter-shaft A and a work-supporting table or bed-plate A Said shaft A is adapted to be driven from any suitable source of power to give rotary motion to the spindle A, and said spindle is provided with asleeve A ,which has sliding, but non-rotative, engagement therewith, which is provided with means by which it may be raised and lowered and is also provided in its lower end with a toolholding chuck A Now referring to the parts constituting my invention, B designates as a whole a hurlingtool which is secured in the chuck A C a die which is adapted to embrace the fitting to be knurled and which is made of two parts or halves in order to receive the fitting, and D is a clamping device by which the two parts of the die are clamped together and the fitting held in position to be acted upon by the hurling-tool. The clamping device is mounted upon a supporting-block E, which is secured rigidly in any suitable manner upon the work-supporting table or bed-plate A of the press. Said clamping devices consist of a stationary jaw D and a movable or swing ing jaw D which is pivoted at one end to the stationary jaw, so as to swing in a horizontal plane. Said clamping-jaws are secured to the supporting-block E by means of bolts or studs d d, which have screw-threaded en gagement with the block, the bolt d passing through the hinged portion of the jaws and forming the pivot-pin therefor and the bolt d being engaged with a bolt-aperture formed partlyin the stationary and partly in the movable jaw at the opposite ends thereof. Said movable jaw is conveniently provided with a handle 01 by which it maybe swung toward and away from the stationary jaw. The movable jaw is locked in its closed position by means of a locking-bar D which is pivotally secured at one end to one of the jawsthe stationary jaw in this instanceby means of a pivot-pin dfland is provided at its opposite end with a nut D placed on the screw-threaded end of said. locking-bar and adapted to be tightenedagainst theou ter side of the movable jaw when the latter is in its closed position, said nut D being convenientlyprovided with a handle D, by which it maybe turned and the locking device may be manipulated.

used in the apparatus described will be of the same exterior conformation and size, so as to fit the said socket. Said dies, as before stated,-

are made of two parts or halves, and as a preferable construction means are provided for retaining each half thereof in fixed relation with the jaw with which it is engaged, so that 'when themovable jaw is swung away from the stationary jaw the parts of the die will be separated, so as to release the fitting previously held thereby without detaching the same from the jaws. This is accomplished in the present instance by means of tap-bolts d which are inserted through the opposite sides of the jaws and engage at their inner ends screw-threaded apertures 1n the die.

With this construction, it will be necessary to set the die but once in the clamping-jaws while operating upon fittings ofa certain design, the parts or handles thereof being separated to release the fittings when the movable jaw is swung away from the stationary jaw and being brought together to clamp a new fitting therein when said jaw is swung back into its closed position.

The tool by which the inner surface of the fitting is knurled or roughened consists of a shank having a tapered portion 13 and a cylindric portion 13*, and having in its upper end a flattened portion B which fits into an angular socket in the chuck A The operative portion of the tool, or that which engages the inner surface of the tubular fitting to be operated upon, consists of two nurlingwheels 13 13, made in the form of short sleeves or cylinders rotatively mounted in any suitable manner upon the end of the shank, with their axes of rotation parallel with the axis of rotation of said shaft. Said nurling wheels are located upon opposite sides of the central axis of the cylindric portion B of the shaft, with their opposite outer sides projecting beyond the planes of the outer sides of the shaft, and, as herein shown, are mounted to rotate upon pins 1), which fit into longitu- 'dinal sockets in the inner end of the shank and are provided on their outer ends with outer endof theshank said wheels are located. Said pins 1) are secured in place by means of locking-pins b, which are inserted into apertures in the shank and engage transverse recesses in said pins. Said nurlingwheels B are herein shown as provided on their outer surfaces with inclined or spirallyarranged ribs and intervening grooves,which ribs and grooves on one wheel extend in a direction opposite to those on the other wheel. The wheels being independently rotative upon the shank and engaging opposite sides of the inner surface of the fitting, will, when said shank is rotated with respect to the fitting and moved endwise therein, turn in opposite directions against the opposite sides of the inner surface of the fitting, so that the ribs of one Wheel will-cut a plurality of parallel spiral grooves which extend in one direction, while the oppositely-arranged ribs in the'other will cut a plurality of spiral grooves which intersect the grooves cut by the first wheel in crisscross arrangement. Obviously the outer or nurling surfaces of the tool may be made of other form than that herein shown. In order that the nurlingtool may readily enter the tubular fitting, said wheels are made of outwardly-tapered form, so that the distance between the opposite sides of the outer ends thereof will be slightly less than the inner diameter of the fitting to be knurled, it being the intention that the mean distance between said opposite sides of the wheels shall be substantially equal to the inner diameter of said tubular.

fittings. Means are also provided for varying the distance between the opposite sides of said hurling-wheels, whereby the tools as a whole may be used on tubular fittings of different internal diameters. This is accomplished in the present instance by dividing the outer end of the shank into two parts by means of a slit B terminatingiu a Weakening-aperture B, which construction permits the opposite halves of the shank on each side of the slit B to be sprung away from each other, said shank being made of a metal which will permit of such movement of the two halves thereof. The means for spreading the two parts of the shanks to increase the distance between the opposite sides of the hurling-wheels consist, as shown in Figs.

6 to 8, inclusive, of two expanding-screws b b which engage interiorly-screw-threaded sockets which'intersect the slit B and are formed partly in one and partly in the other of the two halves of the shank. The outer ends of said sockets are conical and are engaged by the conically-shaped heads b of said screws. Said screw-heads are provided with transverse slots, by means of which they may be engaged by a suitable tool for moving the same inwardly and outwardly within the sockets.

In Figs. 10, 11, 12, and 13 is shownasomewhat-modified form of means for expanding the outer end of the shank. The expandingscrew b in this instance, instead of being located between the wheels B engages a transverse aperture which extends through the shank from one side to the other thereof above said wheels and intersects said slit B Said aperture is made at both ends of conical or outwardly-flaring shape and is engaged at one end by the conical head b of the expanding-bolt b and at its other end by a conically-shaped not b which has screw-threaded engagement with the bolt, said head and nut being made of such size as to be contained entirely within said aperture. \Vith this construction when the bolt is turned into the nut it will act to move both the conical head and nut inwardly, with the result of expanding or spreading the opposite parts of the shank away from each other. The lastdescribed construction is desirable where the tubular part of the fitting is of relatively small diameter and where the nurling-wheelsare so close together as to leave insuflicient space between them for the expanding-bolts, while the first-described construction may be employed for fittings having tubular parts of greater diameter. In said lastmentioned construction the cylindric portio'n B of the shank is reduced, as shown in' Fig. 10, to a diameter less than that of the conical upper part thereof.

In Figs. 14 and 15 are illustrated the dies for holding the fitting or junction-piece which joins the upper horizontal member of the frame with the upper end of the steering-head member and for also holding the fitting or 3' unction-piece which joins said steering-head member with the lower oblique member of the frame. Said fittings (shown in Fig. 21) are designated as E and E, respectively, and consist of main cylindric portions E E and branchcylindricthimblesE E Saidfittings are identical in their construction, but are reversed with respect to the angles which the branch thimbles bear with respect to the main body of the fitting or that portion which engages the steering-head member when said fittings are assembled in the frame. The die shown in Fig. 14 is designed to hold said upper and lower fittings of the steering-head member while the interior surface of the main body portions E or E are being knurled. Said dies, as before stated, are made of two parts or halves F F and are provided on their proximate faces with sernieylindric depressions ff, which when the parts of the die are brought together form a cylindric recess or socket adapted to receive the main body portion E or E of said fittings. Said proximate faces of the parts F F of the die are also provided with other semicylindric depressions f each of which intersects at its inner end at an angle the depression f and opens into one of the outer faces of the die, said depressions f forming when the parts of the die are brought together a cylindric recess or socket adapted to receive the branch portions E or E of said fittings E or E Said die will be throughout their entire length.

made of greater vertical depth than the length of the main body portions of the fittings to be received thereby, in order to afford space inside of said fittings to permit the tool to pass entirely through the fittings, so that the interior surface of said body portions maybe knurled Fig. 15 illustrates in detail a dieemployed for holding said fittings E and E in such manner as to present the branch or thimble portions E or E to the nurling-tool. The parts or halves F F of said die are provided in their proximate faces with obliquely-arranged semicylindrio depressions f f which form when the parts are brought together a socket or recess to receive the body portions of the fittings, and with other semicylindric depressionsf f perpendicular to the outer face of the die, which intersect said depressions f and form sockets to receive the branch portionsof thimbles E or E of the fittings.

In Figs. 16 and 17 are shown in detail dies for holding the seat-post fitting G, which is shown in Fig. 17, and consists of a main cylindric tubular body portion G, a branch tubular thimble G to which the rear end of the upper horizontal member of the frame is attached, and laterally-separated rearwardlydirected lugs G to which are attached the rear oblique members of the frame. Fig. 16 illustrates a die which is adapted to hold the fitting G in position for the tool to enter the branch portion or thimble G thereof. The two parts or halves H constituting said die are provided with obliquely-arranged semicylindric depressions h h, which when brought together form a socket or recess to receive the main body portion G of the fitting, and other depressions h h, which intersect the depressions h and extend to the outer face of the die, perpendicularly thereto, and form when the parts are brought together a socket or recess to receive the branch portion G of the fitting. Said parts of the die are provided also in their proximate faces with short angular depressions 77, h which intersect the depressions h in such relation as to form when the parts are brought together a recess or socket to receivethe lugs G of the fitting. Fig. 17 illustrates adie adapted to hold the fitting G in position for the tool to enter the main body portion thereof, the parts or halves H H of said die being provided in their proximate faces with semicylindrio recesses or depressions h 71 perpendicular to the outer face of the die, and intersecting semicylindric recesses h h, which when brought together form recesses or sockets to receive the main body portion and the branch portion or thimble of the fitting, respectively, and are provided with angular depressions 72. h so formed with respect to the depressions h h as to provide when brought together a socket for the lugs G In Figs. 18, 19, and 20 are shown dies which are employed for holding the crank-hanger fitting in the several positions required to present the several-thimbles or sockets to the action of the nurling-tool. The crank-hanger, which is shown in Fig. 21 and designated by the letter I, consists of a main body portion 1, a f0rwardly-extending thimble 1 to which the rear end of the front oblique member of the frame is attached, an upwardly-directed thimble I to which the lower end of the said member is attached, and two rearwardly-directed thimbles I 1 to which the forward ends of the bottom fork members are attached. Fig. 18 illustrates the die which is adapted to hold the fitting in position for the tool to enter the branch portion or thimble 1 The two parts or halves J J of said die are provided on their proximate faces with relatively wide and deep semicircular depressionsjj, which extend to the laterally opposite faces of the die, and with other depressionsj'j, whichintersect the depressionsjj and extend to the outer'face of the die and perpendicular thereto. Said depressions jj aretapered to form when the parts of the die are brought together a tapered socket to receive the exteriorly-tapered thimble I. The part J of the die is provided with two tapered socketsj j adapted to receive the thimbles I I of the fitting, and the part J thereof is provided with an oppositely-extending tapered socket 7' adapted to receive the thimble I of said fitting. Fig. 19 illustrates a die adapted to hold the fitting I, so that the tool may enter the thimble 1 thereof. Said die consists of two parts or halves J 2 J which are provided in their proximate faces with opposite semicylindric depressionsj j which extend from one side face to the other of said die and are adapted to receive when the parts are brought together the main body of the fitting, and is provided also with other semicircular depressionsj j which intersect said depressions 7' j and are adapted to receive when the parts are brought together the thimble I of the fitting and to hold it in proper relation to the nurling-tool. The part J of the chuck is provided with tapered sockets or recessesj and j j adapted to receive the seat-post thimble 1 and the rear-fork thimbles 1 1 respectively.
