'SPOOL-FINISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 463,688, dated November 24, 1891.

Application filed February 10, 1891. Serial No. 380,941. (No model.)

To all whom it may concern:

Be it known thatl, JOHN M. PARKER, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Spool-Finishing Machines; and I 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, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

In the manufacture of flanged spools and bobbins made of wood, but more especially small spools, such as are commonly used to wind silk thread or twist upon, it has been heretofore a comparatively slow and expensive process to turn the blanks, because the workman is forced to handle them singly that is to say, he first selects a blank, next centers it in the lathe or turning-machine, then cuts away the stock intermediate of the two ends of the blank, and finally drops it from the machine complete.

The object I have in view is to greatly faoilitate the manufacture of spools of the class and hold the blanks 'endwise between them,

and clearers for forcing the spools from the spindles, the turned spools then falling into a suitable receptacle beneath, all as will be more fully hereinafter set forth and claimed.

By means of my invention a workman can tend four hoppers or two machines, his duties being practically to keep the hoppers supplied with the spool-blanks. Thelatter pass singly therefrom to the bottom of the runway or chute, where suitable fingers or feeding mechanism places it in position to be held frictionally between the adjacent ends of the revolving centering and driving spindles,

followed by reducing the blank to form the barrel and forcing it from the spindles. The action of the machine upon the blanks is entirely automatic from the time the blank enters the hopper to its delivery as a finished spool, the rate of production being some fifty spools a minute per feeder.

In the appended three sheets of drawings, illustrating my invention, Figure 1, Sheet 1, is a front side elevation in partial section. Fig. 2 is a side elevation of the knocking-off mechanism at the rear end of the machine. Fig. 3 is a similar view of the knocking-off mechanism at the front end of the machine. Fig. 4 is a plan view of the same correspond ing to Fig. 3. vation of the machine in partial section. Fig. 6 is a horizontal sectional view taken through the lower portion of the runway corresponding to Fig. 14, showing a blank in position therein preparatory to moving the runway rearwardly and turning the blank. Fig. 7 is a similar sectional View taken through the other or front runway corresponding to Fig. 13, the cutter being in the act of operating upon the blank. Figs. 6 and 7 show the relation of the several parts to the driving spindle at the same instant. Fig. 8 is also a horizontal sectional view of the run way, showing mechanism by which it is vibrated. Fig. 9 is an enlarged side elevation in partial section, showing a blank held frictionally between the ends or faces of the driving-spindles. Fig. 10, Sheet 3, is a plan view of the blank-holding hoppers or reservoirs. Fig. 11 is a plan view of the machine, the hoppers and feeding mechanism being omitted. Fig. 12 is a side elevation showing the interior of the lower portion of the hopper and the throat of the runway. Fig. 13 is a side view showing the lower portion of the runway and the feeding mechanism, the relation or position of the parts corresponding to those represented by Fig. 7. Fig. 1% is aview similar to Fig. 13, showing the position of the other runway and corresponding to Fig. 6. Fig. 15 represents enlarged side and end elevations of the wooden blank. Fig. 16 shows similar views of the turned or finished spool, and

Fig. 5, Sheet 2, is an end ele-' Fig. 17 is an enlarged front view of the lower portion of the runway.

In carrying out my invention, represented by the drawings, I have arranged the parts so as to produce a double or duplex machine, the two feeding mechanisms, &c., working alternately. The number of such feeders, &c., may be extended. I find, however, thatit is more convenient and otherwise more practical to use only two in the same machine than a greater number. My improved machine as a whole is indicated by A.

In the drawings, a indicates the vertical frame or legs to which the bed or table a is secured. The latter is provided with a nu mber of short uprights a surmounted by bearings in which the three driving-spindles "1' freely revolve. Each spindle is driven by a continuously-traveling belt 1 (shown by dotted lines,) passing over asmall pulley 2', secured to its spindle. The two outer spindles at the right and left are susceptible of endwise movement, so as to readily receive and release the spool-blanks. The means for effecting such movement consists each of a pivoted lever 0 carrying in its upper end a swivel-bearing 0 in which the outer end of the spindle revolves, the latter having fixed collars, which engage the ends of the bearing 0, thus compelling the spindle to move in unison with the lever. The lever is vibrated by a guided link 0 jointed thereto and carrying at its other end a roll 0, arranged to travel in a cam-groove formed in the cam c, secured to the continuously-revolving shaft 3, as clearly shown in Fig. 1. This shaft is driven by a gear g, intergearing with a smaller gear g, secured to the belt-driven pulley 13, mounted to revolve on a stud-shaft s. The adjacent end portions of the spindles r contiguous to the runways b are reduced in diameter, as at 0' Figs. (5, 7, 9, &c.,'and are provided each with a center pin 1 Fig. 9, having awell-rounded end adapted to readily enter the center hole formed in thespool-blankz. The end orface of each spindle is made to frictionally engage the corresponding end of the blank, thereby holding and revolving it in unison with the spindles. V

To each lever c is jointed, near its upper end, a latch or hook 0, (see Figs. 1 to 4,) arranged to engage a notch 6 formed in the outer end of a horizontally-mounted movable clearer-shaft t. A clearer or knock-01f lever k is adj ustably secured to each shaft t, the whole being so arranged that upon the engagement of the moving latch with the notch the shaft is forced endwise toward the runway by the lever c thereby causing the clearer 7a to engage the'blank or spool and force it from and off the center spindle r, whence it drops into an open receptacle k, Figs. 6, 7, the. Immediately succeeding the release of the spool, and also while the spindle a is still being carried endwise by the said moving lever 0 a pin 0 secured to the latch, engages a fixed bent rod 0 Figs. 2 to 4., and trips or withdraws the latch from the notch, a spring instantly returning the shaft 25 to its normal position, the pin meanwhile riding upon the rod. The shafts are provided with collars i against which the springs bear. Springs 0 serve to insure the engagement of the latches with the respective shafts when the latches are freed from the tripping-rods c. Sometimes the spools frictionally adhere to the adjacent ends of the other or longitudinally-movable spindles r, in lieu of the center spindle. Therefore in such case in order to detach the spool at the proper time I provide a suitably-located stationary clearer 70, which is secured to an upright (L The function of this clearer is to force the spool from the rearwardly-moving revolving spindle upon the engagement of the spool therewith.

To the front side of the bed are secured three bearings v, in which two shafts 4) are mounted to vibrate. A cutter-holder n is se cured to each shaft, each holder being provided with a downwardly-extending arm at", to which at its lower end is jointed a connection 01 the latter in turn being attached to an eccentric e, secured to the cam-shaft s. The arm n is furnished with a comparatively stiff spring '11, the same bearing against the end of the connection 91 thereby rendering the arm somewhat yielding, the latter being slotted transversely to permit a movement of the joint-pin, as shown in Fig. 5. The holders a are adjustable in a lateral direction upon the shafts by means of screwthreaded collars or nuts 11 The cutters 1 Figs. 11 to 14, the, are held in position by screws a an elongated openingn being formed in the upper portion of the holder to receive the cutters. From the foregoing it is obvious that the holder and its cutters vibrate to and fro substantially in unison with the eccentrics movement.

I will next describe the construction of the hoppers and runways leading therefrom. To the top of the standards a, secured to the bed a, are fastened longitudinal ties a and end ties to, the whole forming a rectangular open frame, Fig. 10, upon which the two hoppers (l are mounted. These as drawn consist of two pieces or halves, being divided longitudinally through the center. An inclined reservoir It extends from the back of and communicates with each hopper, into which the spool-blanks z are first deposited and from which the hoppers proper are supplied. The sides of the hoppers are inclined and also curved. The two adjacent sides are normally separated along the lower edge a distance slightly exceeding the thickness of a spool-blank and terminate in wide parallel flanges d which in turn are inwardly bent along the outer edge to form narrow retaining-flanges d, the latter being provided to prevent the blanks from falling through. (See Fig. 12.) In the drawings the two adjacent or inner sides of the hoppers are permanently secured to the frames of; but

the other or outer sides are laterally adjustbevelears a verticall uided shaft 8 carrying one of the gears, a worm-wheel 21;, secured to the lower end of the shaft 8 and a worm w, secured to the cam-shaft 5'. (See Figs. 1,5, the.) Each hopper is provided with a stirrer or agitator f, adj ustably secured to the shaft, the same having a series of arms adapted in revolving to keep the blanks moving rearwardly toward the reservoirs. The arms travel freely in the opening or space formed by the lateral separation of the flanges 61 (See Figs. 10 and 12.) The stirrers are adjusted and held in position by collars n. The bottom of each hopper near its center is provided with downwardly-extending bent ears, the two forming a yoke d to which the upper end of the runway 12, about to be described, is jointed. A pocket 72 is formed at the rear portion of the under side of the hopper contiguous to the reservoir h by further extending the flanges c1 (See Figs. 5 and 12.) This depression also forms a mouth or throat from which the spool-blanks pass singly to the runway. The size of the throatopcning may be varied, as desired, by means of the thin movable slotted plate It and adjusting-screw h, Fig. 12. Each chute or runway Z) is jointed at its upper end to the hopper by means of pins b the sides of the runway having bent ears adapted to receive the pins. (See Figs. 1 and 5.) Each runway practically consists of three pieces-the left and right lateral sides I) b and the front b The two former are provided with inwardlyturned flanges b Figs. 8, 13, &c., thereby forming the back side of the runway and preventing the blanks from falling out during their passage to its mouth I2 The runway is rendered adjustable to receive blanks varying in size, as follows: the front side Z1 is jointed at its upper end at b to the adjacent sides, the lower end having a slotted extension 1), through which passes a retainingscrew 6 attached to an ear formed on the side 6 By means of the arrangement just described, the front 12 is vibrated upon the pivot, thereby adjusting the depth of the runways opening at its mouth Z9 to blanks varying in diameter, the throat-opening at the same time being correspondinglyadjusted by means of the plate 71. Figs. 12 and 13.

In order to change the width of the runway to receive blanks varying in length, one of its sides I) is provided at the back near the lower end (see Fig. 17, due.) with a slotted plate 6 through which a holding-screw 6 passes and is tapped into an ear formed on the opposite piece 6 of the runway, the movable half of the hopper at the same time being correspondingly changed, thereby producing a uniform width for the blanks, the same extending from the pocket It to the mouth I). The lower end of the chute is cutaway at one side to fit a curved stationary guide u, secured to the bed a. (See Figs. 14 and 17.) This guide serves to support the runway in its intermittent vibratory movement. By means of a plate a, hacked by a spring 6 the chute is frictionally held in position upon the guide to during the time it is normally stationary.

it indicates a yielding bent finger or stop adjustably pivoted to an arm to, adjustably secured to an extension 10 of the lower portion of the chute. The front or free end of the stop is beveled and projects upwardly in front of and in close proximity to the bottom blank resting in the chute. (See Figs. 13,14, and 17 The chute is vibrated back and forth by means of a bent link 4%, jointed thereto at m. The opposite portion of the link is provided with a slotted head m in each end of which is tapped an adj usting-screw m. The ends of these screws are adapted to engage a pin m mounted in the upper end of an arm at, secured to the cutter-holder 02 (See Figs. 5, 8, 13, and 14.) From the foregoing it will be seen that although the eccentric 6 causes the cutter-holder to vibrate regularly the runway itself does not travel in unison therewith in either direction, except when the pin m engages the corresponding screw m. Gonsequentlytherunwayremainsstationary twice a short time during a revolution of the cam-shaft s.

I would state that the position of the right runway is indicated by 1, Figs. 1, 7, 11, and 13, the relative position of the other runway at the same time being indicated by 2, Figs. 1, 5, 6, 11, and 14.

A shipper located at the left of the ma chine, consisting, say, of a lever Z, adapted to operate a belt-guide Z mounted in a holder Z, secured to the stud .9, Figs. 5. and 11, affords means whereby the machine can be operated at will.

The following describes the operation of the machine, it being first assumed that the several spindles r and cam-shaft s are all normally working. I would add that the description to follow refers to one set 20f cutters, &c.; but obviously it applies equally to the other set 1, the parts being so adjusted that they work alternately, as hereinbefore stated. The spool-blanks z are deposited in the reservoir, from whence, by means of the revolving stirrer f, they are carried along the space formed between the flanges 01 to the throat of the pivoted runway 11, the blanks falling singly therein, the stirrer acting to keep the runway filled. The blank drops to the mouth of the chute, the latter then being, say, in its forward and, for the time being, stationary position, Fig. 14, and is arrested-and held by the stop 10 the spring e preventing the chute from accidental movement. At the same time the adjacent revolving spindle r is carried ahead toward the right by the corresponding cam c to engage the blank and center it thereon and upon the adjacent end of the revolving middle spindle. \Vhile the blank is being thus centered and frictionally held and revolved the pivoted cutter-holder is moving ahead through the medium of its eccentric, thereby causing the pin m mounted in the end of the arm m", Fig. 1-1, to traverse the space formed in the link-head m and engage the other screw m. The continued movement will force the chute rearwardly, opposed by the spring 6, to its limit upon the guide it, thereby causing the blank to pass out of the mouth I) and over the end of the yielding, stop u the latter, by means of a spring 162, immediately returning to its normal position, a blank at the same time taking the place of the one withdrawn. \Vhile the chute is thus moving rearwardly the cutters y engage the revolving blank and turn the barrel portion .2 therein, the spool a, Fig. lei, being practieally finished at or before the commencement of the movement of the chute in its return or forward stroke, the position of the parts then being substantially as represented by Fig. 13. The revolving eccentric-now upon passing its center causes the cutter-head to vibrate in the opposite or arrow direction, Fig. 13, thereby removing the cutters from contact with the spool. At the same time, too, the corresponding position of the cam 0 causes the lever at the left to move endwise, thereby separating the two spindles and releasing the spool from them, whence it falls into the receptacle it. Usually, however, the spool adheres to one of the spindles, owing to the pressure required to hold it while being turned. In such case the clearer 7c, secured to the shaft 25, moving endwise in unison with the spindle by means of the engagement of the spring-latch c with the shaft, acts to force it from the middle spindle, or in case it adheres to the other spindle the latter in its rearward movement (to the left) causes the spool to engage the stationary clearer 7; or knock-01f, which forces it from the spindle. Meanwhile the runway has been vibrated to the front, thereby bringing another blank into position to be centered upon the spindles, Fig. 14, as before described, thus completing the operation.

\Vhile the spool just referred to is being completed by its mechanism the other runway and corresponding mechanism 1 is working alternately therewith to complete another spool. By this it is apparent, as before stated, that two spools are finished during one revolution of the cam-shaft s.
