ROBERT KING, OF BROOKLYN, NElY YORK.
MACHINE FOR MAKING CYLINDRICAL. PINS AND TUBES OFWOOD.
SPECIFICATION forming part of Letters Patent No. 397,727, elated February 12, 1889.
Application filed December 31, 1887- Serial No. 259,460. (No model.)
To all whom it may concern.-
Be it known that 1, ROBERT KING, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in lllachine's for Making Cylindric Pins and Tubes of \Vood, of which the following is a specification.
My invention relates to machines which comprise a hollow spindle and a tubular eutter carried at the end thereof, and by which cylindric pins or semi-cylindrical sections of such pins and. tubes or hollow cylinders of wood may be cut of any desired length, limited only by the length. of stick from which the pins or sect-ions of pins or tubes are to be made.
The invention will be hereinafter particularly described, and then pointed out in the claim.
In the accompanying drawings, Figure 1 is a longitudinal. elevation, partly in section, of a machine embodying my invention and intended for cutting at the same time from a stick. or bar of wood a semi-cylindric section of a pin and a scmi-cylindric section of a tube larger in diameter than the pin. Fig. 2 is a transverse section of the machine on the plane of the irregular dotted line .e :r, Fig. 1. Fig. 3 is a transverse section, upon a larger scale, of a stick after it has been passed through the machine, showing the sections of the pin and tube which are cut therefrom. Fig. 4 is a longitudi nal section of a hollow spindle and tubular cutter embodying my invention, and including, also, a guide for a rectangular stick,
these parts being intended to form a cylindric pin from a square stick by cutting oft the Fig. 5
four corners thereof at one tq ieration. is a plan. of the parts shown in Fig. l. Fig. 6 is a transverse section on the plane of the dotted line 1 1 Fig. 4. Fig. 7 is a transverse section on the plane of the dotted line 2', l; and Fig. 8 is a transverse section of a hollow spindle and the bed or table extending through the same, i'llustratin g how my invention maybe applied to the trimming cit or forming of moldin which are a segment of a cylinder less than half.
Similar letters of reference designate corresponding parts in all the figures.
In Fig. 3, A designates the stick of wood,
which has formed in it the arc-shaped or semicircular cuts or kerfs a at, extending lengthwise of it and forming from it the semi-cylindric pin-section and the semi-cylindric tubesection a larger in diameter than the pinsection. It is obvious that when two of the sections a are glued or otherwise secured together a cylindric pin or rod will be formed, and when two of the tubular sections a are glued or otherwise joined at their fiat edges a tube or hollow cylinder of wood will be formed.
I am aware that hollow spindles provided with tubular cutters have been before used; but as heretofore constructed thcpin-sections or tube-sections a a could be made only in short lengths,because the stick of wood could not be passed beyond the driving-belt for the spindle; and the object of my invention has been to so construct and arrange the spindle and its appurtenances that the kerfs a a can be formed throughout the entire length of a stick many feet long, thereby producing the pin-sections a or the tube-sections of corresponding length.
Referring now to Figs. 1 and :2, B designates a tubular spindle mounted in bearings O, and carrying at its end a tubular cutter, D, which is of a size to form the kerf a, and B designates a corresponding spindle mounted in bearings C, and having upon its end a smaller tubular cutter, D, adapted to form the kert' u. These spindles B B are arranged in line, and at the feeding end of the machine is a rectangular guide, E, which is of a size to receive the rectangular stick, A, which is to be cut and prevent it from turning. The guide E is placed upon a table, E, which, as here shown, is at each end of the machine, and which has a long tongue-like portion, E eX- tending into and, as here shown, entirely through both spindles B B lengthwise thereof,
and which is upon the same level as the table or bed E. The tongue-like prolongation E of the table or bed E serves to support thelower flat surfaces of the pin and tube sections a o during'thcir passage through the machine,
and as the stick is pushed inward the cutter,
D first forms the kerf a and the cutterD subsequently-forms the kerf a; but it Will'be.
understood that with a long stick of wood IOO l l l l The shaft I? is supported in boxes f upon a frame, 1?, which is free to swing upon a rod, F extending between the end frau'les, (l, of the machine, and
constituting one of the stretcher-s which connect these end frames. Thebclts F F are kept taut by the weight of the shaft F and its pulleys, and also by the weight of the frame F, which hangs virtually in the l'ielts l l and which is left free to rise and fall, for a purpose hereinafter described.
The driviirg-beltF is conducted tothe pullev I? over idler-pulleys f, so that it may be interfere with the principal parts thereof, and
also so that any lowering or rising movement which the shaft l may have will not materially vary the length of the belt F". The idler-pulleys f" are journaled upon an arm, 1"-, which is supported by the rod F and maybe secured in any desired position thereon by a set-screw, f. If the belt F be too slack, the arm f may be turned slightly upon the rod if to tighten the belt, and then be secured in its new position by the set-screw 1".
In order to make the belts F l? as thin as possible, I prefer to make them each of a ban d of steel or other thin metal having its ends brazed or soldered together.
The portions of the spindles ii B which are between their ljiearings constitute the pulley portions of the spindles, and may be roi'ighened or wound with thread or small cord laid on with mucilaginous substance or cement, so as to give the belts a better hold upon them. The belts in passing around the spindles 1 l3 each describe an are which is of less radius than the radius of the cutter I) or 1), and hence the arc of the belt will be accommodated in the kerf a or a. The caps 0* of the lmarings U also have a radius less than the radius of the tuln'llar cutter l.) or Il'f)',and do not therefore interfere with the passage of the stick over the entire length of the spindle, as they are accommodated in the kert' u. or a.
The bearings (I (f are formed. in one piece with or attached to the'table E, so as to form one structure therewith, and this table, with the spindles, maybe removed as one piece from the top of the end frames, G, and have substituted for it the table E. (Shown in Figs. 4: to 7, inclusive.) As the table E (shown in Figs. 1 and 2) has two spindles and cutters, it is adapted to form, from a rectai'igular stick like that shown in Fig. 3 both a semi-cylindric section, c of a pin or red and a semieylindric section, a, of a tube; but the table E (shown in -t to 7, inclusive) carries but a single spindle, B, having upon it a hill)- lar cutter, I), and journaled in bearii'rgs (1*. The spindle and cutter-B I) (shown in Fig. 4.) are intended for cutting a long cylindric pin or rod from a square stick bysimply forming a circular kert' and severing from the stick the triangular corner pieces, s, as ilulicated in liig. 7.
The table It) is constructed with rectangular guides E, for holding the stick in place and jn'eventii'ig its turning, and in this case also the d riving-belt F in passing around the spindle describes an are having a radius less than the radius of the tubular cutter I). The caps are very thin at the points c, which are opposite the two upper corners s of the stick, and u'lay have himgitudii'ial strengthening-ribs c, whieh come between the two opposite upper corners of the stick or on opposite sides of which the two upper corner taken off: at one side of the machine and not pieces, 8, pass, as indicated in Fig. (i. The lower portions of the bearings which are formed in the table or bed E, have holes or channels 0 through which the two lower corner pieces s pass, as shown in Fig. I3, and these two lower corner pieces a pass on the insideof the downwardly-extending portions of the belt l", as shown in Fig. 7.
\l'henv it is desired to form (-ylindrie rods or pins only, the table E may .be removed from the frame 1-, and the table E, with its spindle, substituted therefor, and the same driving-belt, l or 1*", m ay l )(i employed to drive the single spindle B on the table 1!) as was previously employed for driving the. spindle upon the table E, inasmuch as an y difference in the levelof the spindle will be compri nsatml for by the gravitating framel which carries the countor-shaft F.
The table E (shown in Figs. 'l and 2) has a chute, 0, extending from the opening 6, which. receives the tubular cutter l) or l), for couvcyi ng away the chips l'ormed thereby, and the same chute, c, is provided on the table. 11') opposite the opening 0, for conducting the chips formed by that tubular cutter I) thereon. \Yith the parts shown in l! g .-lto 7, inelusive, for forming cylim'lrie pins or rods no tal'dc extending through the spindle is necessary, because the pin or rod mnnpletcly fills the hollow spim'lle, and is amply supportz-ed without such table extending through the spindle.
My invention maybe utilized in forming from sticks of wood moldii'igs which constitute any-sized segment of a cylindm' less than semi-eyliudrie.
I have in Fig. 8 shown a hollow spindle through. which extends a tongue-1i ke bedor table, E having in it a trizn'igular groove, o and in this groove lies' a stick, A, which it is designed to give an arc shape on its surface, so that it will form a quartcr-seginent of a cylinder. Inasmuch as the driving-belt for this spindle will describe an are less in radius than the radlus of the tubular cutter used upon the spindle, the portion. cut off from. the
stick A to form the segmental. molding will pass outside the belt.
The table E (represented in Figs. 4: to '7, inclusive) is shown as Wider than the table E, (shown. in Figs. 1 and 2;) but this is simply because I have illustrated it in Figs. 4 to 7 upon a somewhat larger scale than in Figs. 1 and 2 for the sake of greater clearness. The tables E and IE will in practice be of the same length and width and are interchangeably fitted to the frame G.
\Vhat I claim as my invention and desire to secure by Letters Patent, is
The combination of a hollow spindle carrying a tubular cutter, a driving-belt which in passing around the spindle describes an are less in radius than the radius of said cutter, and a table for the work, having a tongue-like prolongation into or through the' hollow spindle, substantially as herein described.
ROBERT KING.
