v SPECIFICATION forming part of Letters Patent No. 253,778, dated February 14, 1882.

Application filed October 31,1881. (No model.)

To all whom it may concern Be it known that I, HENRY R. SILLMAN, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Machines for Making Spools, Bobbins, and Similar Articles, of which the'following is a specification.

My invention relates to machines for making bobbins, spools, bangs, and other small arti cles of wood, in which the blanks are carried in holders in the periphery of a rotary wheel having a step-by-step or intermittent motion while they are being subjected to the different operations by which they are formed. The r0 tary wheel is provided with dogs for retaining the blanks in the holders; and the invention consists in the combination, with the wheel, of mechanism whereby the dogs-at the proper time are drawn back, first, to permit the insertion of the stick into the holders, and subsequently, to release the bobbins or other articles from the holders.

The invention also consists in the combination, with the rotary wheel and a cutter or cutters, of a pusher shaft or rod adapted to push the bobbins or other articles lengthwise from the wheel, a spindle against which the bobbin or other article is passed, and which is adapted to movelongitudinally,likethepusher, to carry the bobbin or other article into a position to be acted on by said cutter or cutters for turning its periphery.

The invention also consists in the combination, with the aforesaid wheel and the pusher shaft or rod and a longitudinally-movable shaft whereby the bobbin or other article is presented to the cutter or cutters for turning its periphery, of the sand or smoothing roll for finishing the bobbins or other articles.

The invention also consists in various coinbinations of parts, to be hereinafter explained.

In the accompanying drawings, Figure 1 represents a plan of a machine embodying my invention. Fig. 2 represents a vertical section on the dotted line or m, Fig. 1. Fig. 3' represents a detail view of a portion of the rotary wheel, a holder thereof, and a dog arranged adjacentto the holder and Fig. 4. represents adetail sectional view, hereinafter explained.

Similar letters of reference designate'corresponding parts in all the figures.

A designates the main wheel which carries the bobbins, and which has notchesa, constituting holders formed at equal distances apart in its periphery. The wheel A is mounted on a' shaft, A, which is adapted to rotate in suitable bearings in the frame B of the machine, and has an intermittent rotary orstep-by-step motion imparted to it by means of a ratchet- .wheel, A which is fixed upon the shaft A, and a pawl-rod, A engaging therewith, and actuated by an eccentric, A, on the drivingshaft 0. The ratchet-wheel A has its teeth corresponding in number with the number of notches a in the wheel A, and the throw of the eccentric A is such that the wheel is advanced at each step just the distance between two of its notches. In the periphery of the wheel A, adjacent to the notches a, are recesses, in which are fitted sliding dogs I), as seen in Fig. 3, and

these dogs are impelled into the'notches a by springs b, when not otherwise acted on, to cause their points to bite into the wood blanks and hold them in the notches against turning.

The material from which the bobbins are out is in the 'form of a round stick, and it is fed into the notches as they come to the lower side of the wheel in a direction parallel with the shaft A. The stick of wood is fed into the wheel A between rollers c, by which it is guided, and against a stop, 0, (shown in Fig. 1,) which may consist simply of a screw which can be adjusted to allow the stick to be fed through the wheel more or less. As each dog 1) reaches the position where the stick is fed in a projection, 0 upon it strikes against a stop, b which consists of one arm of a bell-crank lever, and the dog is moved back against the force of the spring I) sufficiently to allow the stick to enter the adjacent notch. A rod, 1), which is worked by the eccentric on the driving-shaft O, is. connected to the other arm of the bell-crank stop b and bet'ore'the wheel A is moved forward the stop is moved away from the dog by the eccentric-rod b and cc centric b and the dog is moved forward byits spring to cause its teeth to embed themselves in the blank. The rollers c, or one of them, may be positively rotatedby a belt, 0, and others will feed in the sticks automatically.

Adjacent to the stick as it is fed in is a swing-saw, d, and a mandrel, d, which is supported in a swinging frame, W, as clearly seen in Fig. 2. The saw is driven by means of a belt, 61 passing from a pulley, d, on the driving-shaft to a pulley concentric with the pivot of the frame d and a second belt, (1 leading therefrom toa pulley on the said mandrel. The swinging frame d is connected by a rod,.d with an eccentric, (1 on the driving-shaft O,

' and while the wheel A is still stationary, after such as are commonly employed to turn the journals or pivots on the ends of wood bobbins. the spindle e.

In proximity to the wheel A, and in line with the spindles e e, are stops, rests, or abutmentsff, which are in proximity to the ends of the bobbin-blanks when the wheel A is stationary.

DD designate two shafts, which are parallel with the spindles c e, and which derive their motion from the main driving shaft 0 through transverse shaftsE E and bevel-gearing g g and h h. (Clearly shown in Fig. l.) The shafts D D are rotated at the same speed as the driving-shaft 0. Upon the shafts D D are camsF F, which actuate pivoted levers G G, that bear upon the outer ends of the spin les 6 e, and by these cams and lovers the spindles e c are moved longitudinally toward the wheel A, to cause their cutters to turn journals or pivots on the ends of the bobbins, the bobbins being held against longitudinal movement by the stops, rests, or abutmentsff,and against turning by the dogs Z) in the wheel A. The end of the pivot formed on the bobbin by the cutters on the spindle 0 does nottouch the rest or abutmentf when it comes oppositeit, but said rest or abutment is shouldered, so that the shoulder on the bobbin will be pressed against it by a very slight longitudinal movement of the bobbin produced by the spindle 0, while the pivot on the bobbin will move clear of said rest orabutment. The restsff may be adjusted by screws .8. The cutters of the spindle c act first on one end of the bobbin-blank,

pressing it against the stop or abutment f, and.

the cutters of the spindle c then act upon the opposite end of thebobbin, pressing it against the stop or abutmentf. The levers G G are actuated by the cams F F to move the spindles e 6' toward the wheel, and are actuated in the other direction by springs 9 as seen in Fig. 1. The spindles e e are driven by belts e which may extend from an overhead counter-shaft. (Not here shown.)

On the opposite side of the wheel A from the spindles e e is arranged a pusher shaft or The spindle c is arranged in advance of.

rod, t WlllGll is adapted to be moved longitudinally in its bearings by a pivoted lever, i, and a cam, 43 on the driving-shaft G. On the opposite side of the wheel A, and in line with the pusher shaft or red i, is a small shaft, j, carrying a clutch-piece,j, fast upon it; andj designates a companion clutch-piece which is fixed to or formed with a sleeve, j as best seen in Fig. 4. The sleeve 7' is adapted to rotate in a bearing, 3' and motion is imparted to it and the clutch-piece j" by a belt, 9' extending from a pulley, j, on the drivingshaft. The shaftj is adapted to slide longitudinally in the sleeve 9' to move the clutchpiece j into engagement with the rotary clutchpieeej and it is pressed back to disengage the two clutch-pieces by a spring, j, arranged as shown in Fig. 4.

From the shaft j is suspended a weight, j, which tends to draw the shaft in a directionto move the clutch-piece jinto engagementwith the rotary clutch-piece j but the spring j is more than sufficient to counterbalance this weight, and therefore the shaft j will always be moved toward the wheel A when not otherwise acted upon, but its return will be somewhat retarded by the action of the weight.

Adjacent to the shaft j is a cutter-head, k, which is provided with suitable knives or cutters, and is rotated by a belt,k,from a pulley, on the driving-shaft (J. The knives or cutters in the head kare shaped so as to turn the periphery of the bobbin concavely from end to end to receive the thread,andoppositc to it or side by side with it is arranged a sand-roll, l, which conforms in shape with the finished bobbin, and is adapted to smooth the bobbin asit is turned by being rotated in a contrary direction to that in which the bobbin is rotated. The sand or smoothing roll may be rotated by abeltfrom an overhead counter-shaft in a wellunderstood manner. As the bobbins in the notches of the wheel A are brought into line with'the pusher rod or spindle i and the shaft j the projections b on the dogs I) come into contact with a pivoted stop, m, which is actuated by an eccentric-rod, m, and eccentric m on the driving-shaft O, and the dogs are pushed back, so as to release the bobbins held by them. The'pusher rod or spindleithen moves toward the wheel A and pushes the bobbin against the end of the shaft j, and the further movement of the pusher-rod carries the bobbin into position to be acted on by the cutter-head 7c and the sand-roll band also carries the clutch-piece j into engagement with the rotary clutch-piece 7' thus causing the bobbin to be rapidly ro tated. If desirable, the cutter-head It might be stationary instead of rotary so long as the bobbin is rotated. After the bobbinis finished the pusher-rod or spindlei moves back quickly, butas the shaft j is retarded by the weight j it does not move as quickly, and the pusher rod or spindle 43 moves away from it, thus al lowing the finished bobbin to drop into a suitable receptacle.

IIS

It will be seen from the above that at each stoppage of the wheel A abobbin is being cut oh" by the saw, the opposite ends of two bobbins are having journals or pivots turned on them, and another bobbin is being turned on the periphery.

If the machine is to be employed for making spools, the spindles e 0, instead of carrying cutters, should carry drills or bits for' boring the spools; and if themachine is to be used for making bungs, the spindles e e and the mechanism for operatingthem are entirely dispensed with.

By my invention I provide a simple machine which requires no attention save to feed in the long sticks of wood, and which is capable of working very rapidly, having a capacity of thirty thousand to forty thousand bobbins or spools per day of ten hours, and only requiring one attendant to two or three machines.

What I claim as myinvention, and desire to secure by Letters Patent, is-
