' COIL-WINDING MACHINE.

Application filed January 4, 1921. Serial No. 435,000.

To all whom it may concern:

Be it known that 1, CHARLES FAYER, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Coil-Winding Machines, of which the following is a full, clear, and concise description? a, My invention relates to coil winding machines; that is, to machines'us'ed for the purpose of winding coils of the type used for producing hightension currents, impulses and discharges, and. particularly such coils as are employed in radiographic and X-ray work.

More particularly stated, my invention contemplates improved mechanism for automatically stopping and starting the winding drum, and for so regulating the distribution of the wire as wound thereupon as to cause the stoppage of the drum to take place at exactly the proper instant required by the distribution of the wire upon the drum. That is to say, I make specific provision for the drum to stop turning at the instant when the wire, as wound upon the drum, is completely formed into a layer of a single thickness of the wire. 1

My invention further contemplates the arrangement and adaptation of the mechanism just mentioned, for use in connection with other mechanism, controllable directly by hand, for winding upon the drum afillet or ribbon of paper or other flexible, insulating material, and for cutting off this fillet pe riodically. inorder for it to be formed into bands disposed concentrically, without .interfering with the continu'it'y'of the wire, or with the proper distribution of the convolutions thereof.-

My invention further contemplates an improved stop-motion, specially adapted for use with mechanism of the kind above mentioned.

Reference is made to the accompanying drawings forming a part of this specification, and in .which. like letters indicate like parts throughout the several figures.

Figure 1 is a side elevation of my improved coil winding machine.

Figure 2 is an end elevation of the same. Figure 3 is a diagram of the wiring, and

parts immediately associated therewith.

Mounted upon a base plate 4 are a number of posts 5, 6, 7 and 8, and a frame 9. These parts being used for supporting-various portlons of the mechanism. The'frame is provided with slots 10, 11 arranged in pairs and areused for supporting rolls of

paper

12, 13, the slots 10, 11 being for the purpose of facilitating the removal and replacement of the rolls of paper. Strips 14:, 15 are wound off of these rolls of paper and formed into fl a fillet 16, which is thus of two ply, paper. Either or both of the strips of paper 1 1, 15 may be prepared with an adhesive surface for 'thls purpose. The fillet 16 passes between a pair of presser rolls 17 A shear 18 is provided for the purpose of severing the fillet 16 at intervals, thus cutting it into lengths as desired.

A winding drum is shown at 19, and is used for supporting the coil as wound. This drum carries a cylinder 20, of fiber orother insulating material. The drum is supported upon a revoluble shaft 21, and is provided with a pair of end guards 22, 23, eachhaving the proximate form of a disk.

A brace 24 is mounted upon the posts'6,

7 and is secured to

bearings

25, 26 with 'which these posts are provided. A counter is shown at 27, and 18 mounted upon the brace 24, the latter serving as a'beam for supporting the counter."

Mounted upon the shaft 21'is a pulley 28 for communicating motion to other parts as hereinafter described.

A starting box 29 is mounted upon the post 5. VVires- 31, 32, preferably formed into a cable 33 lead from a source of electricity, not shown, to the starting box 29.-

A pair of

wires

34, 35 lead from the starting box 29 to the counter 27, for the purpose.

of enabling the counter to automatically control the starting box, if this be'desirable.

The starting box is provided with a push button 30 and a 'main switch 32.

An electric motor is shown at 36, and is provided with a sleeve 37 servingas a beargrip handle 39 and shifting the same to the right or left so as to causethe clutch pin 4-1 to enter or leave the slot 40, can throw the shaft 21 into or out of working relation with the electric motor 36. A wire 42 leads from the push button in the starting box 29 to the motor 36, and a wire 43 leads from the main'switch 32 to a binding ost 46 carried by a circuit breaker 48. nother binding post 47 is carried by this circuit breaker, and connected with this binding post is a wire 44, A wire 44 is connected gear 54. carries a pair ofpresser pins 55,

56, disposed diametrically opposite each other and each located adjacent the edge of the gear.. A contact member 57 extends through and-is supported by a plate 58 of insulating material, and a'c'ontact member 59 is mounted upon and carried by an arm 60. The arm 60 is made of metal, and

is mounted upon a bearing 61. The arm 60 carries a presser knob 62, which is rounded as shown in Figure 3, and located partially in the path of travel of each of the

presser pins

55, 56. The parts just described are so formed and arranged that either one of the

presser pins

55, 56, coming into engagement- .with the presser knob 62, causes the arm 60 to swing slightly in a clockwise direction according to Figure 3, and thus move the contact member-59 out of engagement with the contact member. 57. A spring 63 is used for the purpose of shifting the armfiO-back into its normal position-that is into such position that the contact member 59 is in engagement with" the contact member 57.

The worm gear 54. carries a heart cam 64, and engaging this. heart cam is a pin 65, carried by a swinging arm 66. A spring 67 engages the pin 65, and constantly presses the same against the edge of the heart cam. The spring 67 is mounted uponastationary arm 68.

The swinging arm 66 has the form indicated more particularly in Figure 1,- and is provided with a slot 70. The swinging arm 66 carries a bearing 71, which is slidably adjustable along the upper portion of the arm, by aid of ,the slot 70. The bearing 71 carries a pulley 72, which is 'thus adjustable relatively to the swinging arm and supported thereon. V

Mounted upon the post 8 is a bearing 7 3*, carrying an arm 75, the latter supporting a spool 74. A wire 73 is reeled 06? from the spool, and'passes over a pulley 76'and under the pulley 72, being thence wound around the drum 19, as may be understood from Figure 2.

The pulley 76 is carried by a pulley block 77, and this pulley "block is supported upon a cord 78, the'cord being partially wound around 'a lifting drum 79. This drum is supported by a stationary shaft 80. The cord 78 carries a tripping block 81, which may be brought into'engagement with a contact arm 82 whenever the cord 78 is wound up and the pulley 76 thereby raised by means of the lifting drum 79.

A tubular block 83 serves as a limiting stop for preventing excessive upward travel 'of the contact arm 82,- as may be understood,

from Figure 3.

The contact arm 82 carries a plate 8-l,

and from the latter a guide rod 85 extends downwardly. Loosely encircling this guide rod is an eye 86, carried by the pulley block 77. By this arrangement the'pulley block 77 is'in its up and down movements guided by the guide rod 85, 'so as to cause the tripping block 8, in its upward travel, to

be brought accurately and positively into.-

engagement with the adjacent end of the contact arm 82, as indicated more particularly in Figure 3. l

" The contact arm 82 carries a contact boss 87, and adjacent the latter is another contact boss 88. The contact boss 88 is mounted upon a metallic strip 89, and mounted upon this strip is" a binding post 90. The strip 89 and another binding post 91 are mounted upon ,a board 92. The contact arm 82 is pivotally supported below the board 92, and is engaged by a spring 93, whereby it'is always maintained under a gentle tension. Thus the "contact-consisting ofthe bosses 97, 88' is normally-"closed, but is opened whenever the'fpiilley block 77 is raised to its upper limit of travel. The board 92 and parts immediately associated therewith are supported by a stationary arm 94, the latter being mounted 11 upper portion of the post 8. I 1 For the purpose of properly tensionihg' and centering the spool 74 I provide a plunger 95, encircled by a spring 96 and extending through a sleeve 97. This sleeve is pro vided -with an arm 99, and extending through a'hole in the latter is a guide rod 98.

The wiring emplpyed is shown diagrammatically in Figure 3, The board 92 with its accompanying parts includin the contact arm 82 is essentially a-circuit breaker, and this circuit breaker is in series with the circuit breaker 48, which is provided asabove explained with the contact arm 60.. Thus the circuit ofthe system contains two contacts arranged in series with each other and with the motor 36, and so arranged .that the opening of either contact will stop pen the" 32*, wire 32 to source of electricity, not shown, and thence back to wire 31.

If, however, the circuit just traced happens to be open owing to the'positlon occupied by either of the contact arms 60 or82, so that the motor is not energized, the push button 30, contained in the-starting box 2% mav be closed by hand and another circuit thrbugh the motor may now be traced as follows: wire 31, motor .36, wire 42, push button 30, main switch 32, wire 32 to source of electricity, not shown, thence back to wire 31.

The swinging arm 66, the heart cam 64 and various other parts immediately associated with these parts are so proportioned and arranged, relatively to the drum 19,

, that each complete swing of the arm 66 cated carries the pulley 72 a distance approximating the width of the drum 19. Slnce,

however, it may happen that coils of different sizes areto be wound upon this drum,

or in other words since the drum may be virtually wider at one time than at another,

the distance traveled by the pulley should.

be varied accordingly. The operator by adjusting the position of the slide 71 may within reasonable limits vary the length of the stroke or distance of travel of the pulley 76.

The operation of my device is as follows:

The various parts being assembled and arranged as above described, and being in their respective normal positions, the device is operated as set forth below.

I will assume that the electric motor is running, and that the swinging arm 66, the heart cam 64 and various other movable parts occupy the respective positions indifor them in Figure 3. The swinging arm '66 is now swinging to the right according to this figure, and the heart cam is turning in a contra-clockwise direction,

so that the presser pin 56 is approaching the presser knob 62 and the presser pin 56 is recedlng therefrom. By the time the swinging arm 66 reaches the limit of its travel to the right, the presser pin 56 engages the presser knob 62 and rocks the arm in a clockwise direction, so that the contact mem ber 59 is moved out otlenagagement with the contact member 57. This breaks the motor circuit and thereby stops the motor,

so that the various movable parts are brought to a standstill.

The swinging movement of the arm 66 to the right, as just described, carries the pulley 72 to a distance corresponding to the width of the drum 19, so that thewire 7 3 is so delivered to this drum and so wound thereupon as to form a single unbroken layer. hen the motor stops as just stated, the operator brings the end of the fillet 16 into contact with the layer of wire just wound upon the drum 19, and by turning the drum a single revolution by hand, coils the'fillet upon the drum, so asto form a band or ring, the end of the fillet being overlapped by another tportion of the fillet. The operator then actuates the shear 18, and severs the fillet, the, portion thus cut off being of course so disposed as to completely cover the layer of wire. The wire 73 is not severed, however. The operator next starts the motor into action, and for thispurpose closesv the push button 30, or in other words short-circuits the 'circuit breakers. This is only for an instant, however, because as soon as the motor begins to run therotation of the gear wheel 54 carries the presser pin 56 out of engagement with the presser knob 62, so that the arm 60, under pressure from the spring 63, now rocks slightly in a contra-clockwise direction and this brings the contact member 59 into engagement with the contact member 57. This closes the motor circuit independently of the push button 30, so that the motor continuesrunning after pressure upon the push button isrelaxed. The motor continues running until the presser pin 55 engages the presser knob 62 and thus causes the arm 60 to rock slightly as before and again open the motor circuit, stopping the motor as before. Thus the swinging arm 66 swings first to the right and stops, and then swings to the left and stops, each swing of the 'arm in either direction resulting in a single layer of wire being wound around the drum, the operator being allowed time, after the layer is in position, to wind around it a fillet of paper or other flexible insulating material.

Suppose, next, that the wire 7 3 breaks from any cause, usually accidental, or that the wire becomes exhausted. This frees the pulley 76, heretofore held down in its normal position by the tension of the wire, and as a result the pulley block 77, carrying the pulley 76, is lifted upward by means of the lifting drum 79, acting upon the cord 78. As the pulley block 77 rises, .the tripping block 81 engages the contact arm 82, and by rocking it slightly as indicated in Figure 3, moves the contact member 87 out of engagement with the contact member 88. This opens the motor circuit and stops the motor and all movable parts driven thereby.

The operator may now start up the motor by pressing upon ,the push button 30, .so as to short-circuit the circuit breakers as above described, and the motor thus started 'will .plied and properly connected, closure ofthe push button starts up the motor and the latter continues to run until stopped as above' described by the opening of the motor cir-' cuit when the arm 66 is at the limit of its travel in either of two directions; in other words, until either the presser pin or the presser pin 56 engages the presser-knob 62 and rocks the arm 60. g I do not limit myself to the precise mechanism shown and described, as variations may be made therein without departing from the spirit of my invention, the scope of which is commensurate with my claims.
