JULIUS W. LUNDSKOG, OF LYNN, MASSACHUSETTS, ASSIGNOR TO GEN- ERAL ELECTRIC COMPANY, A CORPORATION OF NEW YORK.
WINDING-FORM.
SPECIFICATION forming part of Letters Patent No. 784,799, dated March 14, 1905.
Application filed February 6, 1908. Serial No. 142,128.
To all. 10/7/0771, it neay concern:
Be it known that I, JULIUs W. LUNDSKOG, a citizen of the United States, residing at Lynn, county of Essex, State of Massachusetts, have invented certain new and useful Improvements in Winding-Forms, of which the following is a specification.
The present invention relates to forms for winding coils, and more especially to those intended for armatures. These forms as usually constructed are capable of being used only for coils of certain specified characterthat is to say, the number of layers and the size of wire is the same in all cases.
One object of thepresenti'nvention is to provide a winding-form on which coils having different numbers of layers or turns can be formed or coils composed of conductors of different diameters.
A further object of the invention is to provide a form capable of giving to the coil the proper configuration in a single operation, which is so arranged that the coil when completed can be readily removed.
The invention also relates to certain details of construction which tend to simplify and improve the form, as will be more fully described and claimed hereinafter.
In the accompanying drawings, which form a part of this specification, Figure 1 is a back plan view of a winding-form, showing a gage and clamp for holding the wire. Fig. 2 is a section through the clamp. Fig. 3 is a longitudinal section of the clamp. Fig. i is a section on line i 4 of Fig. 7. Fig. 5 is an enlarged view showing the passage-Way, taken on line 5 5 of Fig. 7. Fig. 6 is a similar view to Fig. 5, taken on line 6 6 of Fig. 7. Fig. 7 is a view looking in the direction of the arrow on line 7 in Fig. 4:, and Fig. 8 is a front perspective view of the winding-form with its detachable plate removed in order to illustrate how the coil can be taken ofi the form when completed.
In carrying out my invention the base is given the desired configuration and its side walls are angularly disposed, so that the coil when completed will fit into the core-slots of the dynamo-electric machine. To the top of the base is detachably secured a plate upon which the conductors forming one side of the coil rest during the winding of the coil. Mounted at a point on the base opposite the plate is an adjustable sliding piece with which the conductors engage, and the position of this piece for each layer or turn varies with the diameter of the conductor being wound. For each turn the said piece occupies a new position. In addition to assisting informing the coil the sliding piece acts as a clamping means to retain the turn or turns in place.
Referring to Figs. 1, 4, and 8, 1 is a metal frame or base that is adapted to be mounted upon a support or standard (not illustrated) which is so constructed that it allows the winding-form to turn in any direction in a given plane. The sides of the base are inclined to each other, so as to give the proper relation to the sides of the coil. It is to be noted in this connection that the coils are adapted to fit into radial slots in the core of a dynamoelectric machine. In order to form or shape one side of the coil, an adjustable piece 2 isprovided, which moves in parallel guides 3, the latter being fixedly attached to the base and inclined at an angle thereto. Attached to the guides are extensionsfl", that may be formed integral or held in place by screws. The extensions 2" assist in holding the sliding plate in place. In order to move the sliding plate up and down, a pin 4 is secured to the under side of the inclined support 3 and acts as a pivot for the lever 5. This lever has a camslot 6 formed in its lower end, which engages with the pin 7 on the adjustable sliding piece or plate 2. A slot 8 is formed in the upper portion of the inclined support and is concentrically arranged with respect to the pin at. or-king in the slot is a stud 9, that is screwthreaded on its outer end to receive the handwheel or clamping nut 10. The stud also passes through the lever 5. \V hen the nut is seated, the lever and sliding piece 2 are clamped in a fixed position. The slot in the lower portion of the lever 5 being eccentrically disposed with respect to the pivot 4, Fig. 7, any motion given to the upper end of the lever will move the sliding piece up or down, as the case may be. In order to form the opposite side of the coil, a detachable plate 11 is secured to the base 1 by lugs 12, which have holes formed therein. A sliding bolt 13 enters these holes and secures the parts in fixed working relation. To prevent the bolt from slipping out of the lugs on the plate 11, a small block 1 1 is secured to said plate. Secured to the end of the detachable plate is a wire clamping or retaining device 16, Fig. 1, having an extension 17, which acts as a gage in measuring the length of the wires forming the leads. These leads are used to connect the coil to the commutator-segments. WV hen the coil is completed, the plate 11 is detached to allow it to be removed. This is accomplished by slipping the bolt out of engagement with the lugs 12 on the base.
Referring to the clamping device for the conductors, (best shown in Figs. 2 and 3,) 18 is a stud passing through a cup-shaped receptacle 19, that is secured to the gage 17. At the other end of the stud is a nut which is used to clamp the wire in the cu p-shaped receptacle to prevent the wire from slipping when the coil is being wound.
Referring to Figs. 1 and 8, two offset-forming hooks 19 are mounted on the base at opposite ends, and two offset-forming hooks 19" are mounted on opposite'ends of the detachable plate 11. The offsets in the coil are provided so as to enable the coils to overlap when in place on the core of the dynamo-electric machine.
Referring now more particularly to Figs. 4:, 5, and 6, 20 is the wall or end of the adjustable sliding plate 2, which engages with the wires and assists in forming the coil. This wall or end also presses the wires of the coil against the projections 21, and it also preserves the tension on the wires from the opposite side. After a coil has been wound the gage 24, which is mounted on the under side of the base, is used to measure the length of the commutator-lead, so that the leads of all the coils will be the same length. One side of the base is provided with an inclined Wall or face 22, that is adapted to receive the conductors which are to form the coil. The inclination of this wall depends upon the are that is to be covered by the finished coil. The detachable plate 11 has a wire-receiving face 23, which forms a right angle with the face 22, Fig. 4. By reason of this arrangement the finished coil can be made of such a section that it has three wires on one side and three wires deep or it can have two Wires on one side and three deep. Obviously other combinations can be made with my improved form which need not be specificallymentioned. The opposite side of the base is provided with an inclined face or wall 21, and situated at right angles thereto is a wall or face 20, carried by the adjustable sliding plate 2. 1n the present instance three conductors are being wound in multiple. Hence the inner wire engages with the wall 21, as shown in Fig. 4, the remaining wires resting on the first. Fig. 5 shows the sliding plate moved back to receive the second turn, layer, or convolution, and Fig. 6 shows three layers, each composed of three conductors. The present coil is square in cross-section; but it can be of any rectangular shape desired.
Assuming now that it is desired to wind a coil and that the form is mounted on a suitable support, the operator takes the required number of wires and, starting from the gage 17, clamps the wires at 16 and winds them against the walls 22, then across the end of the form and through the offset-forming hooks, at the same time giving the Wires a slight twist, thus bringing them in contact with the projection 21. During the interval that the first layer or convolution is being applied the sliding piece 2 is held in place by the hand-wheel or nut 10. After the second side is wound the plate clamps the conductors in their normal position and the wires are passed through the offset-forming hooks at the second end. After passing over the projections 21 the wires engage the face 20 of the sliding plate or piece 2, which forms the second side of the finished coil. The operation is repeated until the desired number of convolutions have been made. Each time the Wire passes the sliding plate the hand-wheel is unscrewed and the lever is moved so that it raises the sliding piece, and the wires are inserted in the space thus formed. This operation is repeated the required number of times and the ends of the last turn form the commutator-leads and are on the top side of the coil. The wire for the lead is measured by a gage 24 beforeitis cut. Pieces of string are slipped around the coil and tied to hold the mass together. After the coil is completed the bolt 18 is released from engagement with the lugs 12, thus releasing the upper plate 11. The hand-wheel 10 is also released, which permits the coil to be removed.
In accordance with the provisions of the patent statutes I have described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof; but I desire to have it understood that the apparatus shown is only illustrative and that the invention can be carried out by other equivalent means.
