1 Claim.
This invention relates to coil winding machines and more particularly to a counting mechanism for indicating when a predetermined .number of turns have been wound by the machine in the manufacture of a given coil.
In winding coil units in which numerous circuits are incorporated and provided with individual terminals, or in which are embodied groups of windings difiering in the size of wire, number of turns, or points at which terminals must be connected, it is essential for the operator to be able to determine at any given instant the exact stage of the winding. An object of this invention is to provide a mechanism of the type described constructed and arranged to indicate the completion of any predetermined number of turns or fraction of turns at successive points in the winding of any given coil.
A further object is to provide a turn counting mechanism having an improved arrangement of parts which are simple and rugged in construction and reliable and accurate in operation.
These and other objects which will be apparent to those skilled in this particular art are accomplished by means of the invention illustrated in the accompanying drawings in which- Fig. 1 is a view in elevation of a turn counting mechanism constructed in accordance with one embodiment of this invention, parts being broken away to show certain details of construction, and
Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1.
Fig. 3 is a view in elevation of an index finger.
The particular embodiment of the present invention which has been chosen for illustration includes an indicating disc secured to the extended hub 6 of a worm gear I rotatably mounted on a supporting stud B secured in one arm 9 of a U-shaped frame Ill which is pivoted to a supporting bracket I I on a frame supporting bolt I2. The beveled periphery I3 of the disc 5 is provided with a circumferential series of outwardly extending slots I4 adapted to receive index fingers l5 for cooperating with a marker I6 or pin positioned on the bracket II adjacent the periphery of the indicating disc. The slots are spaced apart a distance equal to the amountof rotation of the disc for each turn of wire wound.
A handle I1 is formed on or connected to the U-shaped frame I0 for moving the same about the supporting pivot l2 for the purpose of connesting or disconnecting the disc driving worm gear I with a driving worm l8 on a counter shaft I9 which is driven through the gearing 20' from the winding spindle 2| of the associated coil winding machine. A pivoted latch arm 22 is 6- mounted on the bracket II for engaging the handle to hold the gear I and worm I8- in driving connection, and a spring 23 is connected to the handle for raising the gear I to disconnect it from the worm when the latch 22 is released. The index fingers are provided with points 24 which extend laterally from the associated finger so as to be offset from the longitudinal axis of the finger. As a result of this arrangement a given finger can be mounted in any predetermined slot so that the point will lie in the axis of the slot as indicated at 25' in Fig. 1, to the right of the slot as indicated at 25" or to the left of the slot as indicated at 25', depending upon whether the pin is placed in a slot so as to position the ofiset point in a line with the associated slot, or to the right, or to the left, respectively. The formation of the point is such that when extending laterally as indicated at or 25' it cooperates with the marker It to 25 indicate the completion of a fractional number of turns when opposite the marker 16, while when employed as shown at 25' it indicates the completion of a whole number of turns when it reaches a position opposite the marker. Hence, if it is required that a certain winding have 80 turns, for example, or that a tap shall be applied to a winding at the end of 80 turns, an index finger would be so located that its point would cooperate with the marker IE to indicate the completion of 80 /2 turns, as shown at 25", at which stage in the winding the operator would stop the machine, to connect the necessary terminal, to change the type of wire or to perform any other requisite operation. On the other hand, when a coil winding having 89 turns, for example, is required, or it is desired to apply a tap or the like to a winding at the end of 89 turns, an index finger l5 will be located in the slot numbered 89 with the point 24 in line with the axis of the slot, as shown at 25'. Then when the disc reaches a position in which the point is opposite the stationary marker IS the operator knows that exactly 89 turns have been wound. Similarly, if it should be again necessary to stop the machine after winding say 93 turns, an index finger would be located in the slot numbered 94 with the point turned to the right as indicated at 25". The point 24 would then be positioned exactly half way between the slots numbered 93 and 94, and when moved by rotation of the disc to a position opposite the stationary marker l6 would indicate the completion of 93 turns.
In the illustrated embodiment, the disc 5 has slots I4 which are designated in numerical order on the face of the disc by a suitable dial or scale, and the gearing between the disc and the winding spindle 2| of the associated machine is in the ratio of 100 to 1, so that one revolution of the winding spindle rotates the disc 5 a distance exactly equal to the distance between adjacent notches l4.
A revolution counter 30 for indicating the number of revolutions of the disc 5 is positioned .on the frame IO' and connected to the disc through gearing 3| and shaft 32 secured to the extended hub 5 of the driving gear I. It will be apparent that in the present arrangement, in which the disc 5 revolves once for every hundred turns, that the counter 30 will indicate hundreds of turns. 4
In the operation of the device the dial is set at zero and the handle I! moved to connectthe disc 5 with the driving mechanism, the latch 22 serving to hold the handle I! in such position. Operation of the machine produces rotation of the disc 5 in which the operator has placed the index fingers l5 to indicate the successive points in the winding of thecoil at which terminals are to be connected, or other operations performed in accordance with coil specifications. As the coil is wound, the disc 5 is rotated and the operator isable to stop the machine at the predetermined successive points in the winding of the coil as indicated by the movement of the successive index fingers to positions opposite the marker IS. The distance between the center of each slot l4 equals the amount of rotation of the disc for each turn of coil wound. Obvious- 14 1y, any number of index fingers can be employed to indicate any number of successive points in a given coil. The counter is reset by releasing the latch 22 and disconnecting the driving mechanism to permit free turning of the disc to 1! any desired starting point.
I claim as my invention:
The combination in a turn counting mechanism of a rotatable machine driven disc having a plurality of index fingers receiving slots formed m therein, a stationary marker associated with the circumference of said disc, and an index finger having an axially offset index point, said finger being adapted to be located in one of said slots with said point in alignment with said slot or with said point located at one side of said slot to cooperate with said stationary marker for indicating the completion of a predetermined number of complete or fractional turns.
