MACHINE.
SPECIFICATION forming part of Letters Patent No. 740,958, dated October 6, 1903. Application filed January 31 1902. Serial No. 92,044. (No model.)
To 00% whom it nay concern:
Be it known that I, SIMON W. WARDWELL, a citizen of the United States, and a resident of Providence, in the county of Providence and State of Rhode Island, have invented an Improvement in Winding-lllachines,set forth 'in the annexed specification.
My invention relates to winding-machines, and pertains particularly to machines for winding wire and similar materials.
The object of my invention is to provide devices whereby wire may be wound ,like thread, in self-supporting cops or packages and without injury-to the surface of the wire or in' structure and'will therefore not be described in detail. They comprise a rotating copholder or winding-spindle a, a reciprocating guide I), a cam c to actuate the guide, atraverse-bar d to carry the guide and driven by the cam,a traverse-frame e,in which the traverse-bar is mounted and reciprocated, movable to and from the winding-spindle, and devices intermediate the spindle and the cam whereby the relative speed of the two is controlled.
The general structure of the guide,the traverse-bar,and connections whereby it is driven from the cam is fully described in my pending application, Serial No. 70,253.
The tube or core on which the wire is wound is secured to the winding-spindle by any adequate means, (indicated in the drawings as a screw for expanding the extremity of the spindle.)
Attached to the spindle a near the end of the traverse next to the'machine is the disk f, in the edge of which notches are cut at intervals, in which is secured the end of the wire preparatory to winding. The machine,
as illustrated in the drawings, is adapted to wind insulated wire into magnet-coils, as they are termed, and the large diameter of the diskf insures a sufficient length of projecting wire for connections that must be made in using the magnets. The wire is secured in the manner shown at g.
It is impossible for wire -to draw over such sharp bends and turns as those over which yarn may be drawn. The point at which such sharp bends would occur in this machine is at the reciprocating guide, and to remedy it a sheave or guide-wheel h is employed in conjunction with the guide 6 to so raise the wire from the latter that it shall pass through the eye or groove of the guide without the short bends that would occur were the wheel or sheave not employed. The wheel his mounted on the guide-holder 1; on ears or brackets either attached to said holder or formed integral therewith. t
In Winding coils for magnet and similar work it is advantageous to have the winding stop each time at the end of the package at which the winding was started, so that both ends of the wire shall project from the same end of the finished coil.
Provision is made whereby the winding is arrested when the package wound has attained a given diameter in the sizing-screw j, which is mounted in a member of the stopping devices to be engaged by the traverseframe e when it has swung back to a predetermined distance from the winding-spindle a.
In the traverse-frame and opposite the sizing-screw is mounted a swinging member k, pivoted in a slot that opens into the guide- Way of the traverse-bar d. An ear Z is formed on the swinging member opposite the sizingscrew j, and the edge opposite the ear is so formed that when the traverse-frame is swung back and the ear Z brought into engagement with the sizing-screw a projection m on the traverse-bar engages the said edge, swings the member k, and shifts the member which carries the sizing-screw to cause the arrest of the winding. This projection m is secured to the traverse-bar and travels in a groove n. in the traverse-frame.
The supply-spool 0 is secured to a rotatable spindle p, which is mounted in appropriate bearings on the bracket q, attached to the machine. Secured to the spindle is the circular brake-disk 4", upon the periphery of which bears the brake s. The latter is carried on an arm 15, which swings from the top of an arm a, projecting upward from the bracket q. At the extremity of another arm, 1), projecting outward from the bracket q, is mounted the bell-crank lever to, from one arm, 00, of which is suspended the weight 2', and to the other arm, 2, is secured a spring 3. The latter is secured by one end in an eye 4 of the arm t, which when the brake s bears on the disk r is normally in line with the axis about which the lever to rocks. The other end of the spring is secured to a collar 5, adjustable on the arm 2. The degree of pressure with which the brake sis pressed against the disk 1" can obviously be varied by varying the position of the lever-arm 2. When in the position indicated by the dotted lines of Fig. 1, there is no pressure exerted between the brake and its disk, as the pull of the spring is directly toward the axis of the pin 6, on which the brake-arm swings, therefore exerting no tendency to swing it about that axis. If, on the other hand, the arm 2 were shifted into line with the axis of the disk 1", the spring would act on the brake with the full strength of its tension. As the spring acts upon the arm 2 in a line passing through the axis of the lever to it does not tend to rotate the latter about its axis, and hence the lever can be shifted to vary the brake-pressure with practically no resistance to such movement. The weight 2 tends to rock the lever to into such position that the spring shall exert its maximum effect on the brake s and hold the arm 2 in contact and engagement with the arm '7 of the lever 8. The lever S is also mounted in the top of the arm u and is secured to a rock-shaft 9, at the opposite end of which is secured a grooved sector 10. A
weight 11 is suspended from the latter by.
means of a cord attached to the eye or hook 12. A relatively long arm 13, carrying a sheave or wheel 14, serves as a slack-controller. The sheave 14 is maintained in the position indicated by the full lines by the weight 11 and is limited in its movement under the action of the weight 11 by suitable meansin the structure shown by the arch 15 of the lever 8adapted to engage with the top of the arm to.
The operation of my machine is as follows: Preparatory to winding, the end of the wire is drawn from its spool on the supply-spindle 10, over the take-up sheave 14 and the guidesheave h, through the guide b to the windingspindle a. When starting the machine, the pull on the wire incident to the start shifts the position of the sheave 14, causing the on which the lever to swings.
pressure of the brake on its disk r to be relieved, permitting the supply to rotate more freely. Should the supply rotate too freely, however, and cause the wire to slacken, the sheave 14 promptly shifts under the action of the weight 11 to maintain the wire taut and the tension uniform. As the sheave 14 shifts, the lower arm 7 of the slack-controlling or take-up lever is correspondingly moved to vary the position of the brake-spring 3, and thereby the direction of its action on the brake s and intensity of pressure of the latter on its disk r. If the resistance to delivcry of the wire'increases, the brake-pressure is relieved. If the delivery is too free, the brake-pressure is increased to restrain the rotation of the supply. As the packagewound increases in diameter the traverse frame swings back toward the sizing-screwj. The latter engages the ear Z and swings the memberkinto the path of travel of the projection m, which latter acts through the member is to shift the sizing-screw and cause the winding to be arrested at the same end of the package as that from which it was started. If for any reason it is desirable to withhold the brake from engagement with its disk, the
arm 2 of the lever to can be swung to the right, Fig. 1, of the position indicated by the dotted lines. The pull of the spring then shifts the brake-arm If from its normal position and the eye 4 from in line with the axis The spring then acts upon and swings both the lever 20 and the arm t to the right, overcoming the pull of the weight .2 until the two engage and their movement is arrested, thus removing and maintaining the brake s away from its disk. .To return it thereto, it is necessary simply to push the arm 2 to the left, Fig. 1, beyond the position indicated by dotted lines, when the eye 4 is again brought into line with the axis of the lever to, and the spring 3,
With my improved structure the greatest possible degree of variation in the brakepressure may be obtained without effect on the takeup devices. The adjustments of the brake and of the take-up are independent and hence simple. The weight 2 is made of sufficient amount to control the slack in the material wound without reference to the tension of the spring 3, and vice versa.
I have shown the preferred embodiment of my invention; but it is obvious that structural modifications may be made which would also embody the novel correlation of parts which constitute my invention, and also that though the machine has been described as for wire winding it may be employed for winding other materials.
While I have referred to a magnet-coil consisting of covered wire wound as shown, I do not here clain this peculiar form of coil.
