CORD MACHINE.

Application filed July 18, 1925. seriai u 44,425.

covered cord and in a most satisfactory and uniform manner.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and While the invention is not restricted to the exact details of construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof, reference is had to the accompanying drawings in which like reference characters designate the same parts in the several views, and in which Figure 1 is a side elevation showing a preferred embodiment of my new construction.

Fig. 2 is a vertical sectional detail substantially on the line 22 of Fig. 3.

Fig. 3 is a front elevation, parts section.

A Fig. 4 is an enlarged sectional detail on being a the 1-1118 4 of Fig. 1.

. Fig! 5 is a detail view of the guiding means for the covering threads.

Referrin now more specifically to the drawings show my construction-as comprising a rigid framework 10 of generally rectangular construction andcomprising two side membersll and also having top and bottom plates 12 and 13' secured rigidly in any suitable manner both for supporting and housing the movable parts of the mechanism and also to provide ample clearances for observation and access to the operative mechanism. The lower plate 13 includes a stationary bearing 14 upward through which extends a stationary shaft 15 carrying. at its upper end a stationary disk 16, subject, however. to vertical adjustment with the shaft 315 by manipulation of the hand wheel 17 or the like at the bottom.

Theupper supportlng plate bears a central bearing 18 downward from which pro jects a tubular shaft 19 and upon which is journaled a loose pulley 20 below the frame plate 12. On its u per surface this plate carries a stationary bearing collar 21.

Supported upon the collar 21 and adapted for rotation or adjustment around the vertical axis thereof is a spool supporting frame 22 having any suitable number of upwardly projecting spindles for spools of threads 23 which are usually of finishin or ornamental character in the making 0 covered cords or ropes. The central portion of this frame supports a guide member 24 in the form of an annular crown and supported in elevated position by means of legs 25 giving a clear vision not only through but beneath the crown. This crown as shown best in- Fig. 5 is provided with numerous holes 26 formed directly therethrough horizontally and preferably in stag ered relation or in two series circumferentia 1y. The sik threads from the spools 23 are threaded inward through these holes 26 and are guided thence downward through the open center of the frame and into or through the collar 21 below it.

At any convenient place. another "s 001 supporting frame or rack 27 is provide as j at the rear of the main parts of the machine, upon which are journaled a multiplicity of spools 28 from which the main body cords 29 are delivered through a guide 30 near the top of the rack and from which they are directed to the tubular guide shown as a whole at 31 and shown best in Figs. 2 and 4.

The guide just referred to comprises a tube 32 having at its upper end a smooth round surface guide eye 33 made of some suitable wear resisting material such. as

glass, flint, or porcelain. Secured as by screw threads to the lower end of this tube 32 is a conical member 34 having a bore or passageway 35 in alignment with the bore through the tube but having a restricted bore vadjacent to the point or apex of the cone through which 1 the body cords or threads 29 are drawn. 36 indicates a handie, the main portion of which is strai ht as it projects downward through the tu ular members just referred to and terminates in a conical or tapered point 37 which is adapted to project in variable degrees through the restricted apex of the 'cone 34L. The upper end of this handle is bent into a goose neck at 38 and is provided with any" suitable loop or analogousmeans for clamping it in position as by means of a screw 39 co-operating with a bracket 40 sup ported by a horizontal arm 41 connected to a standard 42 fixed to the upper side of the frame 22. By vertical adjustment and manipulation of the handle the point thereof may be projected more or less from the cone for the purpose of varying the size or hard ness of the cord being formed. While the handle is fixed to and adjustable with respect to the clamp or bracket 40, the tube itself is independently adjustable with respect to the bracket and adapted to be locked in place by means of a thumb screw 43 or its equivalent.

WVithin the collar 21 is'positioned the upper end of a guide tube 44 having its free or receiving end fitted with a wear resisting eye 45 of glass, porcelain, or the like, and over and downward through which the covering threads or cords 23 are guided and within which the cord or rope'is twisted.

Mounted vertically within the frame 10 and adapted for rapid rotation around -a vertical axis therewithin is a frame or flier 46 whose lower end is located between the fixed disk 16 and the lowerframe member 14 already described. The lower end of this frame or flier constitutes at 47 a brake hub with which co-operates a brake shoe or strap 48 having associated therewith a foot piece 49 whereby the application of the operators foot downward thereto will tighten the brake and control or stop the rotation of the flier. The flier is operated by means of a belt 50 operating over either the loose pulley 20 or the pulley 51 fixed to or constituting a part of the upper end of the flier frame 46. .Any suitable belt shifting yoke including a handle 52 may be provided to shift thebelt.

53 indicates a horizontal shaft journaled within the lowerportion of the frame and indicated as having sprocket wheels 54: at

both ends outside the frame 46. Fixed adv justably along the shaft 53 is a, friction wheel 55 adapted to co-operate with the friction disk 16 when the latter is adjusted upward by manipulation of the screw 17. By adJustment of the wheel 55 along the shaft and from the axis of the flier and disk 16 the rate of' rotation of the wheel and its shaft 53 will be increased. A set screw or its equivalent maybe employed to fix the wheel at the proper position along the shaft. 56 indicates a pair of sprocket chains operating over larger sprocket wheels 57 fixed to a shaft 58 at the upper end of the flier frame parallel to the shaft 53. Because of the disparity in size of the wheels 54 and 57 the upper shaft is driven at a lower speed'than the lower one. Within the frame there are fixed to the shaft 58 three different elements ,-lirst, a friction pulley 59 at the center, secondly a grooved pulley 60 at one end of the shaft, and thirdly, a worm 61 at the other end of the shaft. all three of which will be driven in unison with the shaft.

Meshing with the worm 61 is a worm wheel 68 to the axle 69 of which is attached a sprocket Wheel '70 driving a sprocket chain 71 over a double sprocket wheel 72. The second sprocket chain 7 3, drives another double sprocket wheel 74 which in turn operates a chain 75 carrying a guide eye 76,

equal to the length of the spool or reel 62.

\Vith the machine constructed as above set forth and with the threads 29 and 23 threaded through the several guides as described past a guide roller 77 over the pulley 59 and thence around direction pulleys 78 through the guide eye 76, the threads are attached to the reel 62 preliminary to forminga cable or rope R. The belt 50 is then shifted from the loose pulley 20 to the tight pulley 51 onthe flier and with the power in operation the flier will begiven a speed of rotation according to the speed of the belt and in a direct manner operating at relatively high speed, for instance 800 R. P. M., around the axis coinciding with the screw 17 and collar 21. The disk 16 being stationary and the wheel 55 rolling thereon and. revolving around the axis of the flier and disk, the wheel and its axle 53 will be rotated, the direction of movement of the several parts being indicated by arrows. and the rolling of the shaft 53 and wheels 54 will cause simultaneous movement of the chains 56 and rotation of the shaft 58 in the same direction as the shaft 53. The rotation therefore of the grooved pulley 60 will cause the rotation of the wheel around its axis in a direction contrary to the revolution -of the wheel 55. The cord or rope being attached to the reel will accordingly be drawn toward and coiled upon the reel as a result of the rotation of the reel 62. The action of the worm 61 and gearing from it to and including the guide 76 will cause the movement of the guide 76 along with the chain 75 in runs parallel to the axis of the reel. The movement of the guide up anddown in this manner is relatively slow because of the well known action of the worm 61 and is timed in such a manner as to approximate the time for thedesired twisting action upon the cord or rope. The draft on the cord or rope due to the winding of the reel and the action of the pulley 59 compels the tread of the threads or strands from the Several spools 23 and 28. The

the travel of which guide is substantially empty one is put into its place.

twisting of all the strands together takes place somewhere between the cone 34 and the guide roller 7 '7 which is carried by and rotated with the flier.

The flier and all the parts carried thereby are so balanced that there is practically no tendency for it to vibrate while rotating at high speed. Co-operating with each of the chains 56 is a guide 79 having rollers 80 serving to confine both runs of the chain and so prevent them from being thrown outward by centrifugal force. These guides are carried by the vertical parts of the framework. When the reel is filled with cord or rope it is removable by loosening the axis pins from the frame and anew or Even though the flier may be operating at high speed as above set forth, it may be set quickly after shifting the belt, by the application of the foot tothe treadle 49, setting the brake 48. The action of the reel and iding means for the cord is just the same as though the flier were stationary, these parts all being carried in a self contained unit or structure. The provision for the rotation of the frame 22 enables the operator to thread the fibers of silk or the like through the guides either initially orat a subsequent time as in the event of the breakage of a thread. By its rotation he is able to swing any portion of the frame around. to wherever hemay be standing as at the side or front of the machine. This is an item of considerable importance in practice. The adjustment of the needle 36 up or downwith respect to the point where the twisting takes placeis for the purpose of varyingflthe hardness or fullness of the cord,-the higher the needle 1s ad usted the closer or harder will the twisting be done.
