Referring to the drawings; for a detailed description of the invention, in Figs. l to, 3, a wire coiling machine is generally indicated by the numeral 20. The machine basically comprises an upstanding frame consisting of a post or column 2 1', a hase member 22, in the form of a pair of spaced parallel angle supports and an over-. hanging head p rt n 23 h ead pqr iqn b in p ed to carry a, fiyer assembly 24;, shown in dotted lines in Fig. l and in detail on sheet 2, Eivotally secured to. post 21, as at 25, andbzneath and in line with head poro 3 are c mp emen ar nt test e as n m 26 which are adapted to enclose fiyer assembly 24 duringthe operation thereof to protect the operator of the machine against injuries resulting from wire whip. Hinge lock means 27 are provided on casing members 26 for retaining the members in closed position during the operation of the machine and for releasing the members when it is desired to have access to the fiyer assembly for repair or similar purposes. When hinge lock means 27 are released as by removing 1pc]; rod 2711, the complementary casing members 26 may he pivoted around hinges 25to their open position as shown in dottedlines in Fig. 3. Pivotally mounted atop head portion 23 of the frame is a wire guiding means 28, which may include a pulley 29 and a substantially U-sLaped wire support 31) carried by a support 31,, for guiding wire W from a source of supply (not shown) to the fiyer assembly, for a purpose to be hereinafter described. A wire receiving means 32 which may be in the form of a pall t or similar support, but is here shown as a drum 32a is positioned below and in coaxial alignment with protective casing 26 and fiyer assembly 24 for receiving coils C of wire emanating therefrom. Though it is not necessary to the proper functioning of machine 20, a cone shaped guide 33, or similar member, may be provided in the wire receiving means for controlling the receipt of wire therein.

Directing our attention to Figs. 4 through 10, a more detailed description of fiyer assembly 2 4 is given. A housing member 34, which includes a substantially drum shaped neck portion 35 and an integral depending support portion 36, is rotatably mounted on head 23 of the machine frame for rotation around an axis of rotation X X. The housing is mounted in head 23 through a sleeve 37. The sleeve, which is supported and fixed against rotation with respect to the head by blocks or plates 38 extend'ng between the l of h h a e tends nt neck. rem ss 35 to rotatably carry e hass i thrs sh lisatia 'niean 39 of any type pommonly knowh to the art. A toothed drive collar 35a is secured to the upper end of neck portion 35 for driving engagement with a chain belt 35b connecting the same to a motor 34a mounted in post 21 of the machine frame. It will be observed that the housing is rotated around the axis of rotation X-X by motor 34;: through chain belt'3 b and toothed drive is keyed to the capstan as at .41a and connected to the 'support through bearing means 42 of any commonly known type. It will be noted that support 36 is provided with a bulgedv portion 43 concentric with shaft 41 adjacent the end directed away from capstan 40 for accommodating a gear wheel 44 connected to the shaft for a purpose to be hereinafter explained. Theshaft-4I is 7 further rotatably supported with respect to support portion 36 through a bearing ring 45, connected to the support by bolts 46 or similar-means, and a bearing means 47. A bolt 48 threadingly engages shaft 41 and retains capstan 40 against outward movement with .respect thereto.. v 7

Connected to housing 34, and extending upwardly through neck portion 35 and sleeve 37. concentric with the axis of rotation XX. is a quill shaft 49 for guiding wire W from the wire guiding means 28 (see Fig. l) to the capstan. A capstan drive shaft or spindle 50, which is provided with a toothed drive pulley 51 at its outer end, ensleeves quill shaft 49' and extends downwardly through sleeve 37. The ,drive shaft is provided at its end directed away from drive pulley 5l with a gear member 52. A worm shaft 53 is rotatably. carried by support portion 36 of the housingthrough bearing means 54 (see Fig. 7) and carries at its upper end a gear wheel 55 for meshing with drive shaft gear wheel 52. Intermediate the bearings 54 supporting shaft 53 is a worm gear 56 which is adapted to mesh with the teeth of gear-44 connected to capstan shaft 41. A motor'40a (see Fig. l) mounted in post 21 of the machine frame is connected through a chain belt 57 or similar means to the toothed drive pulley 51. It will be observed that on rotating pulley 51,.by motor 400 through belt 57, that drive shaft 50 and gear 52 are rotated. The rotation of gear 52, which meshes with gear 55 of worm shaft 53, turns worm 56 whichis in meshing engagement with capstan gear 44 thereby rotating the capstan. 1-

It should be noted at this point, that capstan 40, which isadapted toreceive wire W guided theretothrough quill shaft 49, is provided with a pair of parallel peripheral tracks 58 and 59, one of said tracks, track 58, being narrower than the other track. It will be observed from an examination of Fig. 9 that narrow track 58 is of slightly less diameter than track 59, as indicated at 58a, this structure serving a purpose to be hereinafter explained.

Mounted on support portion 36 of the'housing for pivotal movement toward and away from capstan 40 is a pressure roller 60 which includes a roller wheel, 761 rotatably mounted on an arm 62 pivotally connected to the support as at 63. The pressure roller, which is adapted to engage capstan 40 in track 59 thereof, is pressed in the direction of the capstan by a helical spring 64 which has one end connected to-the pressure roller at the intersection. of arm 62 and roller 61 and its other end secured to support 36 in any convenient manner. A wire guiding member 65, which is pivotally mounted on support member 36 adjacent the side of pressure roller 60 directed away from capstan 40, includes a sheave or pulley type roller 66 rotatably mounted on an arm 67 that is pivotally connected to the support as at 68. Spring means 69, having one end con'nectedto support 36 and the other end connected to the wire guiding member 65 at the intersection of arm 67 and sheave 66, acts on the V 4 wire guiding member to move it away from pressure roller 60. A wire casting device 70 of any type commonly known to the wire art is mounted on support portion 36 operably between wire guiding member 65 and capstan 40.

In the operation of the afore-described wire coiling machine, wire W is guided by wire guiding means 28 and quill shaft 49 to wire receiving track 58 of capstan 40 and therearound for one turn, indicated at a in Fig. 10. On completing one turn around track 58 the wire is passed around sheave 66 of wire guide member 65 as indicated at b and thereafter to wire casting device 70. The wire is operably engaged with the wire casting device and a then wound in a pluralityof turns c, a', etc., on track 59 of the capstan from whence it is passed out of the bottom of fiyer assembly 24 in coils C as indicated at e for disposition in a wire receiving means 32. The pressure roller member 60 is adapted to engage the plurality of turns c, d in track 59 and forces the same into engagement therewith. The rotation of capstan 40, as described above, acts to draw wire W from the source of supply and through the path a, b, c,,d, e,- at which time it is cast, to eliminate undesirable twists, and forms coils of the wire. The housing which is being simultaneously periphery vof capstan 40, of a diameter smaller than the other track (see 58a in FigLlO). 'On forming one turn of wire around track 58, of lesser diameter, and thereafter around a guide 65 to the other track, the desired wire'tension is provided when the capstan isrotated.

.It is often necessary or desirable in the packaging and coiling of wire to form coils of different sizes; this may be necessary due to the difference in gauges of the wire or to the packaging requirements therefor. In order to accomplish this effect without the necessity .of rotating the wire receiving means or changing blocks, as was taught by the prior art, thisinvention contemplates varying the relative speed of rotation between the capstan and the fiyer assembly. While the relative rotational speed of the capstan and fiyer assembly may be varied by conventional gearing or similar means, in the illus trated embodiment of the invention the desired result is achieved by regulating the driving speed of the motors 34a and 40a; the concept of separate driving means for the capstan and-fiyer assembly, as embodied in the invention, facilitates varying the relative rotational speeds. It is contemplated that the drive speed of themotors will be controlled by potentiometer controls 71, however, other means will be obvious to those skilled in the art.

Thus, among others, the several objects of the invention as aforenoted are achieved. Obviously, numerous changes in the structure may be resorted to withoutdeparting from the spirit of the invention as defined by the claims. r
