Specification of Letters Patent.
Application led October 22, 1920. Serial No. 418,854.
of NewJersey, have invented a new and Im-v proved Arma'ture-Winding Machine, of
which thelfollowing is a full, clear, and'leX-H act description.
This invention relates to armature winding machines, and has for van object the provision of a machine in which an ar1nature, with the c0mmutator--attached, canbe rewound in a simple and eicient manner with a maximum saving of time and labor; A-Anotherobject of the invention resides in the provision of means lwhereby with, a simple adjustment a\.plurality of diferent ltypes of armature windings can be made.
A ,further object res'rles in the provision of means whereby an acc ate count of the number of armature turn X wound at any particular instant may be "ada y A still further object of the invention is to provide mechanism whereby during the windin of the armaturel coils the ends of the coi s which are to be connected to the commutator are conveniently led out and .held in proper position so that their attachment to the commutator after winding can be achieved in a very simple and eicient manner.
Another object of the invention resides in the particular construction and arrange'- ment of parts to be hereinafter described and claimed in connection withthe accompanying drawings.
ur invention in general comprises a rotatable element upon which the armature to beV wound and its shaft with commutator attached ma be mounted. Associated with this rotatab e element is a support for the armature wire which, during the movement of the armature on the rotatable element, guidesthe wires into the proper slots.-- Means are provided in certain circumstances to periodically remove the wire sup ort from the pathA of the armature shaft. also provided vand associated with the rotatable element, and to which the ends of a previously wound coil are connected, so
eans are that during the winding of a subsequent coil these ends are firmly heldrduringl the wind- 1ng so that -they may be connected to the Patented Mar. 7, 1922.
commutator after al1 the coils have been woundin a simple and efficient manner.
Further features of the invention will be apparent from a consideration of the followlng descrlption and claims whentaken 1n connectlon with the'following drawings.
The invention is illustrated in the drawings, of which Figure 1 is a side elevation of the machlne; 1
Figure 2'is a plan view of part of the machine, particularly with reerence to the means for supporting the armature wire;
Figure 3 is a, detail sectional view of the mechanism for actuating the armature wire support Figure @is a detail view of the indicating means;
Figure 5 is another sectiontaken on the line 5-5 of Figure 4;
Figure 6 is a partial detail View;
Figure 7 is a partial 'planv view of the means for supporting one -end of the armature shaft;
Figure 8 is a section through one end of the support for the armature shaft; and
Figure 9 is a view of thesupport for another end of the shaft.
As shown in the drawings, the invention comprises a base portion or pedestal 1 having a vertically extended standard portion 2 and a horizontal standard portion 3. The upper rear portion of the standard 3 is provided with a bearing 4 for a shaft 5 which sov at vits outer end is suitably journaled in the 4main base portion 1. At the upper end of the standard portion 2 there is a horizontally Aextending platform 6. The Jfront end of the shaft 5, which is hollow, is provided with an enlarged head portion? provided with apertures 8. and 9 therein (see .Figure 6) through which the ends 10A and 11 of arms 12 and 13 extend. .These arms 12 and 13 are spaced apart any required distance by reason of the adjustment vof the end portions 10 and 11 of the slots 8 and 9. Any adjusted position of the end portions 10 and 11 Vmay be fixed by means of set screws 14 and 15 engaging therewith inthe head port1on'7.
Within the shaft 5 is a hollow tube 16 which ts loosely therein and at its rear end is/oonfastened'to the bearing portion 4.' lVithin.
' the tube 16 a needle f19 is adapted to move.
This needle is connected at its rear end by a spring2() with the pin 17. The movement of the needle 19 within the tube 16 is limited by the engagement of a slot 21 in thevneedle with a pin 22 fastened in the'walls fythe tube 16. The front end of the needle 19\is` W13 and adjustable by means of set screws provided with a hook portion 23 which, in a manner hereinafterto be described, is adapter1 for a certain purpose to engage the ends of the armature wires.
Between the pedestal 1 and the bearing 4 a power-driven pulley 24 is fixed on the shaft 5. This pulley may be driven by any suitable means, such as a power cable 25. Also fixed on. the shaft 5 is a bevel gear 26 adapted to mesh with a bevel gear 27 mounted on the lower end of a shaft 28.
This shaft is journaled at its lower end in the base portion 1 and at its upper end is journaled in the end of the platform 6. At the extreme upper end of shaft 28 a cam element 29 is carried, the functioning of which will be hereinafter explained. idway of the shaft 28 is aworm gear 30 adapted to mesh with a pinion 31. The worm ear 30 may be formed on a sleeve `30 which can be slipped over the shaft 28 and fastened thereto by any suitable means. The `inion 31 is mounted on a stub shaft 32. his shaft 32 is adapted to be journaled in a block 33 adapted to slide in a slot V34 of a bracket 35 extending from the standard 2. The other end of the stub shaft 32 is connected to an indicator or pointer 36 which is adapted'to move over the face of an indicator plate 37. This indicator plate is loosely mounted on the stub shaft 32 and, as shown in Figure 4,'is connected to the standard 2 by means of a set screw 38 engaging the standard through a slot 39 in the plate 37. The block 33 is provided with flange portions 40 and 41 engagin the lateral faces of the slot 34, whereby t e movement of the block 33 and the slot 34 is directed. A pin 42 fastened to a portion of the bracket 35 is adapted to be connected to one end of a spring 43, the other end of which is suitably connected to the stub shaft 32. This spring 43 tends to hold the indi-V c ator or pointer 36 in a normal position. A link `connection 44 is made with the stub shaft 32 at the end thereof adjacent the indicator plate 37, so that when a pull is exerted on this connection' 44 the stub shaft 32 with the pinion 31 thereon is moved i backward to draw the pinion 31 out of mesh with the ar 30. At this instant the spring 43 will t row the indicator point back'to normal position. This mechanism provides a.v ready means whereby the counter can be returned to zero position.
V'Between the arms 12 and 13 there is adapted to be supported an armature 45 in which are the usual slots 46 for the reception of the armature coils. lThis armature is mounted on a shaft 47 and the ends of the sha-ft are suitably supported in the ends of the arms 12 and 13. One end of the shaft 47 is supported on the arm 13 and is gripped between blocks 48 and 49 suitably seated in an aperture inthe end of the arm 5() to clamp the blocks against the shaft 47. The other end of the shaft 47 is supported on the end of arm'12 and isfgripped between blocks 51 and 52 which are slidable in a rectangular frame 53 and are adjusted against the shaft 47 by meansof set screws 54. This rectangillar frame 53 is connected by pins 55 to a ratchet wheel 56 and moves therewith. This ratchet wheel is held in any particular position by a pawl 57 backed by a spring 58, both the pawl and the spring being pivoted on the end of arm 12. The ratchet wheel 56 is connected to a bushing o r sleeve l59 which extends through a suitable aperture in the end of arm 12 and is threaded on its other end. This threaded portion is adapted to be engaged by an interiorly threaded collar 60 whereby the bushing 59 and the ratchet wheel 56 may be rigidly clamped to the end ofV arm 12. By reason of the fact that the rectangular arm 53 rigidly grips the end of shaft 47, and this rectangular frame is lrigidly connected to the ratchet wheel 56, the shaft 47 is moved whenever the ratchet wheel 56 is moved. This is for a purpose hereinafter to be described.
In Figure 1 the slots 46 are shown extended in a direction parallel to the axis of the shaft 47, although in different types of armatures these slots may extend in different directions. l For instance, they may extend in a direction from right to left as viewed in Figure 1, making an angle with the direction of their position shown in Figure 1. It is desired to wind the wire 61 into the slots 46 in the desired manner, and in order to do this as rapidly as possible there is provided a holder or support for the wire 61 which is in the `form of a bell-crank lever having an arm 62 depending from the pivot .point 63 on the platform 6. 0n the lower end of this arm 62 is an adjustable plate 64 having pulleys 65 and 66 suitably positioned thereon and over which ther-wire 61 is adapted to run. vThe -other end of the bell-crank lever is provided with an arm 68 extending rearwardly above the platform 6 and having on its end an adjustable plate 68. This adjustable plate is suitably apertured to reapertured to receive a threaded stem 73 of a thumb nut 74. The lower end of this threaded stem 73 has an enlarged head portion thereon suitably seated in a co-operating. roove 75 in the upper end of the shaft y manipulating the thumb nut 74, the position of the shaft 70 within the bushing sleeve 69 can be adjusted. This adjustment varies the stroke of the bell-crank lever and thereby varies the movement of the adjustable plate 64 carrying the wire.
In windingthe form or armature shown in Figure 1, the arms12 and 13 are rotated, and it is desired to wind a coil in the slot shown in line with the` shaft and in one directly opposite on the opposite side of the shaft. To do this the endl of the, adjustable plate 64 must lie in line withv the shaft during the time that the wire 61 isbeing led in each slot. However, when the shaft is rotated there is a point of time in its rotation when it would contact with the end of the plate 64. To avoid this, the plate 64 is moved out of the line of travel of the shaft 47 for an instant each time that its engagement is about to take' place. This lateral movement of the wire support is effected by the movement of the bell-crank lever through the action ofv avcam roller 71 in relation to a cam element 29 disposed on the upper end of shaft 28. This cam element is provided with a plurality of cams 76 and 77 thereon. The roller 71 is shown contacting with the cam 76, the curvature of which is so distinct as to cause a lateral movement of the wire support of plate 64 at the instant in the rotation'of the shaft 47 when the shaft would otherwise contact with the wire support. Immediately after the shaft has passed this point in its travel the wire support is moved backl into its proper position vin line with the slot in which the slot is being led.l A spring 78 is disposed between the arm 67 and the platform 6 to effect the movement of the arm 67 in one direction.
' If Vthe slots are inclined at an angleto the mentioned.
axis of the shaft, of course the movement of the wire support may be effected by varying the shape of the cam in any well-known manner. It will be observed, in Figure 1 particularly, that the cam 77 is of a differ- In theoperation o f the. device the wire threaded through the support, as shown,and one end of'itiis'fastenedto the shaft 47 and then placed in one of the slots 46 which has been positioned, as shown, corresponding to the position of the slot designated 46 in Figure 1. It is desired to wind the armature coil in this slot 46` and in the slot opposite it on vthe other side of the shaft. After having fastened the end of the wire to the shaft by any suitable means, the shaft 5 is rotated in the proper direction to rotate the arms 12 and 13 and with them the armature. As the shaft 47 moves from the position shown in Figure 1, the cam action above described momentarily moves the end of the wire support out of the path of the shaft and then moves it back immediately into its proper position again ready to lead the wire in the slot on the opposite side of the armature. After the required number of turns have been wound in any particular slot, the wire is pulled and-fa loop thereof is led over to the hook 23 of the needle 19, as shown in Figure 1. The remaining portion of the wire is then introduced into a new slot. This new slot is moved into the position occupied by the slot just wound by moving the ratchet wheel 56 the desired distance to bring the slot into position. In
,order to move the ratchet wheel, the upper support for the shaft 47, shown in Figure 9, must be released slightly .to permit the movement of the shaft, but the lower gripping members 51 and 52 need not be released since they move with the ratchet wheel 56. It willy therefore, be observed that while the next slot is being wound with its coils that the ends of the wires, which have as above described been pulled out and connected to the hook 23, are being twisted.' This twisted condition is shown in Figure 1 and represents the condition of the wires such as adapt them very readilyto be solderedvto the particular commutator section to which they are to be connected. As each slot is wound with a coil the ends are drawn j out and connected in turnA tothe hook por-l tion 23, so that when the complete winding on the armature is finished there 'willVv be a plurality of twisted ends projecting from one end thereof which are to be properly insulated and later soldered to the commutator section.v
It .will also be observed that by supporting the armature on its frame, comprising the 4arms 12 and 13, and winding with this mechanism it is not necessary to remove the commutator therefrom. This particular provision of the apparatus shown makes it a 'very simple matter to rewind ali arma-i ture or motors and generators in repair shops; and this canrbe done at high speed since by reason of the cam portion of the wire support this support moves out of the way of the armature shaft during its revolution at whateverspeed it attains.
While only one form of armature winding is shown', it will be apparent that many different forms of windings may be placed on the armature by this machine, and these various forms and manners of winding can be wound by this machine without materially varying the apparatus or the principle of its operationwhich' constitute *our invention.
