IMPROVEMENT IN MACHINES FOR TURNING SPOOLS.
Specification forming part of Letters Patent No. 139,935, dated June 17, 1873; application filed July 6, 1872.
To all whom it may concern:
Be it known that we, EZRA G. WALKER and WILLIAM M. GOODING, both of Newark, in the State of New Jersey, have invented an Improvement in Machines for Turning Spools for Thread, 8110.; and we do hereby declare the following to be a full and correct description of the same, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of the machine. Fig. 2 is an end elevation of the same; and Figs. 3 to 15 inclusive are detail views of the various parts of the machine.
The same letter or reference number is used to designate the same part wherever it occurs.
The object of our invention is to make the machine automatic and self -feeding and it consists in new devices and new combinations of existing devices, constructed, arranged, and
. operating in the mannerhereinafter more particularly set forth.
The machine is supported by a stout frame, A A. Power is applied to pulley B at the end of main shaft 6 by means of a band, D, from a prime-mover. On shaft 6 is a cam, J, which is shown in side View and section in Fig. 4. This cam is grooved on one side to receive a pin projectingfrom lever 13, by which arran gement a vibratory movement is imparted to lever 13-on its pivot or fulcrum 17 in the lower end of the depending bracket E. To the upper end of lever 13 is attached the sliding table Z, which carries the holding and cutting apparatus. On one end of this sliding table is a standard, e, (see Figs. 1 and 8,) on the upper end of which turns the shaft of the holding-reel f, which I call the spider.- To the same standard is pivoted the weighted leverh, the end of which is curved in the opposite direction to the curves of the reel-arms, so that the spool-blank may be held securely between the two. To an arm of the standard c is also pivoted the spring-latch lever g, (see Fig. 3,) the inner end of which enters :the notches in the escapement 12 on the-end of the shaft of reel f. On the opposite end of the sliding table Z to that on which the standard 6 is placed, is the tool-post tof the shape shown. On top of this post are attached, by a clamp and screw, 9, the cutting-tools u, of which there are five, one to cut the flat bottom of the spool, two to is pivoted to a sliding rod, y,-which passes through the back lathe-head 5. The rotation of the cam a imparts a reciprocating movement to the sliding rod y, causing it to advance toward or recede from the chuck-pin of the mandrel 14. There is a block, a, on the end of .rod y, to which is attached a cutter, 0,
for turning the end of the spool. Beyond theedge-cam a there is a pulley on main shaft 6, which, by means of belt 61, drives pulley 21 on the end of the shaft 22, on which the agitators b b are fixed. These agitators are shown in Figs. 1 and 2 and 15 in side and edge view. They are of different diameters, the two in nermost ones being smaller than those outside. They pass up into the hopper 0 through an opening in its bottom, and by their revolution agitate the spool-blanks, which are placed in said hopper. Between the inner pair of agitators there is on shaft 22 a pulley or drum, 16, which, with drum 3, carries an endless belt, 2, which forms a moving bottom to the hopper G. On this moving bottom the spool-blanks are carried and delivered to the trough r, Figs. 1 and 14, from which they are taken by the spider. The form of the trough is clearly shown in the drawings, Fig. 14 representing it in top, side, and end Views, and in section. (1 marks the back of the trough, and p a curved guide, placed just back of a vertical slot in the trough, to turn the arms f of the spider as it moves back to take up the spoolblank from the trough. The trough r is supported on an arm projecting up from the top of the frame, as shown in Fig. 1. A stop, 4, (Figs. 1 and 14,) is placed directly in front of the end of the trough to arrest the progress of the blanks at the proper point. The man drel 14 of the lathe, which ishung and turns in boxes, supported by a bracket, G, projecting up from the top of the frame A, has a pulley, 23, upon it, driven by belt 24. The front end of the mandrel is received in a block, K, (see Figs. 1, 5, and 7,) which forms part of head 12, attached to the front of bracket G. The chuck-pin, upon which the spool blanks are held while turning, is at the front end of the mandrel. Fixed to theface of block K is a cutter for trimming the end of the spool. To head 12 is attached the stop 4. In block K, just below the mandrel 14, is placed an ejector, l, operated by a bell-crank lever, on, (see Fig. 5,) having its fulcrum in an arm projecting from the head 12. The upper arm of lever m is retracted by a spring, not shown, and holds back the ejector until the spool is turned. When the slide Z is carrying the tool-post back, after the completion of the spool, the lower arm of lever m rides up on an inclined loose latch, 7, pivoted to a small bracket on the slide Z, and forces the ejector I out to detach the spool from the chuck-pin. The latch 7 and its attachment are shown in side and end view in Fig. 6.
The operation of the machine is as follows The spool-blanks are placed in the the hopper O, and, as the agitators revolve, arrange themselves longitudinally upon the endless belt 2, and are carried by it into the trough 1', along which they continue to move until the further end of the first blank comesin contact with the stop 4, by which it is arrested. At this instant the first blank is seized between the two arms of the spider and the curved end of lever h, and carried by the movement of slide Z in front of the chuck-pin of the lathe. The slide-rod y at the same time advances, and the pin on its end enters one end of the blank and forces the other end upon the chuck-pin. The return movement of slide Z then brings the cutters u in contact with the revolving blank, and it receives the desired form, the outer end surfaces being turned by the tools on the blocks n and K. When the turningis completed, the slide Z retracts the cuttingtools, and the slide-rod y recedes, while the ejector l is forced out and drives the finished spool off the chuck-pin. The operation is thus completed and may be repeated indefinitely. After the blanks are inserted in the hopper the machineis self-feeding, and its operation perfectly automatic.
Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-
l. The combination and arrangement of the hopper O, agitators b b, endless belt 2, trough 4', and stop 4., in the inanner and for the purpose described.
2. The combination of the trough 1', guide p, spider f, and curved lever g, with the slide Z, for the purpose of receiving the blank and carrying it into the lathe, as set forth.
3. The combination and arrangement of the sliding rod y, blocks n and K, cutters o, and lathe-mandrel 14, in the manner and for the purpose specified.
4. In a machine for turning spools, the combination of the carrying'mechanism fg and the cutting-tools it, supported as described, with the slide Z, all operating as described.
