The machine of which this invention forms a part is designed for the purpose of making dust mops, or similar articles, by the twisting of strands of cotton or other suitable mate rial between wires constituting a core, the particular invention forming the subject matter of this case comprising mechanism for controlling the twisting operation, but in connection with the illustration of this mechanism other" parts comprising the machine as a whole are shown to some extent, some of which parts are not specifically referred to in the description herein, but which parts will be found more specifically set forth and described in a copending application of Serial Number 120,358, filed July 3, 1926, to another invention embodied in the same machine, and to which reference is hereby made for such understanding as may be desired of parts shown herein but not specifically comprising a part of the present invent-ion.

In the accompanying drawings the numeral 10 denotes the base of this improved machine having standards 11 risingtherefrom and com prising the ends of the machine frame as a whole, said standards being connected by a beam 12 extending from one to the other of said standards and secured thereto at the upper portion thereof. A bracket 13 comprising uprights 14 is secured to the upper surface of the beam 12, this bracket in fact comprising the head stock of the machine and including a spindle 15 mounted for longitudinal movement in a clamp sleeve 16 having a flared end or mouth to receive chuck jaws 17 of spring formation secured tosaid spindle and adapt 'ed to be closed when drawn into the clampslecve by endwise movement of said spindle, in a manner that will be readily understood. Said clamp sleeve is rotatably mounted in bearings in the upper ends of the uprights 14 and a chuck aw clamping collar 18 is mounted for endwise movement on said clamp sleeve to actuate jaw clamping levers 19 pivotally mounted in ai c'lamp lever support 20 secured to an adjusting block 21 attached to the he slide 23 maybe actuated as by means of a hand lever 25pivotally mounted on the bracket 13 and having a toothed end in engagement with a rack on saidsliue, as shown in Figure 1 of the drawings. The jaws 17 are adapted to grasp the ends of wires 26 between which the mass 270i mop material has been placed in any desired manner, usually by a mechanical operatioin-said wires and mass resting upon a table 28 pivotally supmported by arms 29 extendingupwardly from the front of the beam 'l2 and as shown in Figure 10 of the drawings. The table is connected by a rod 30 with a foot treadle 31, said parts being held in their upward positions as bymeans of a spring 32,,and the treadle being pivotally supported by the ends 11 of the main frame.

A tail stock 33 is mountedfor sliding move ment on the'beam 12 at that end thereof opposite the head stock, said tail stock'having a fixed holdin 'aw 34 and )ivoted holdin s l l I a: aw 35, the latter being operated as by means of a cam 36-on a jaw clamping shaft 37 to clamp the ends of the wires 26 while being twisted, said shaft 37 being vertically mount to a shaft 41 supporting the handle 25, from v en in the tail stock and having pinion 88 in mesh with a rack at one end of a connecting rod-39 that also has a rack at its opposite end in mesh with the teeth of a pinion 40 secured which it will be seen that the handle 25 is connected to simultaneously operate the clamping jaws on both the head and tail stocks. alsobe connected by a shart 13 anuintermesl'iingpinions, as shownin-Figures 5 and 8,

as a means for manual operation of the clamp jaws from the tail stock when such may be desired.

The tail stock may be held at the backward limit of its movement by means of a weight supportedfby a flexible connection over a sheave andattached to the tail stock, and a cushioning-devicei l5 of any suitable construction may be employed, it de ired, to retard movement of the tail stock backwardly.

This invention has much to do with the mechanism for controlling tl e winding operation of the machine hereinbefore de- A handle l2 on the tail stock may scribed, and to this end a driving pulley 46 is secured to a driving sleeve 47 rotatably mounted in a bearing in the upper end of one of the standards 11, and as shown in Figure 7 of the drawings, said pulley being driven as by means of a belt 48 extending from any suitable source of power, as "from a motor mounted on the frame of the machine. Said pulley has in its hub a recess to receive one member 19 of a twisting clutch, the other member 50 of said clutch being mounted on e the spindle 15 and splined thereto to permit novement of said spindle endwise independently of the clutch member. This clutch is of the well known type of roller clutches and that comprise rollers 51 mounted in wedge shaped spaces between the two clutch members and controlled in their movements by means of spacers 52 projecting from a clutch actuator 53 mounted on the clutch member 50 and independently rotatable thereon to a limited extent. This actuator has recesses 5% for springs 55, one end ofeach of said springs being secured to the actuator and the other end 01 each of said springs being secured to a flange 56 on the clutch member 50, whereby by the action of said springs said clutch member and actuator are caused to rotate in opposite directions to move the rollers 51 into the narrow part of the we lge shaped spaces and therebyfconnect the clutch members for simultaneous rotation. T he actuator hasa stop nose 57 positioned to engage a clutch disengaging lever 58 secured to a rock shaft 59 mounted in bearings on the bracket 15 and having a clutch disengaging arm 60 containing a spring pressed plunger 61 pivotally attached to a clutch actuating finger 62 mounted on a pivot on the bracket 18 with its free end projecting into a hole in a spring pressed clutch actuating rod 63 mounted. for reciprocating movement in the bracket 13 and on the beam 12, as shown in Figures 1, 7 and 12 of the drawings.-

A spring pressed clutch controlling rod 64 is mounted for endwise reciprocating movement on the'beam 12 in the path of movement of the tail stock and as shown in Figures 4 to 6, 8 and 9 of the drawings, the other end of said rod being adapted to encounter one end of a clutch cont-rolling lever 65 pivotally supported on the beam 12 andadapted to be engaged by a detent 66v projecting from a detent lever 67 pivotally supported on the beam 12 and wit-hone end pivotally connected to a. clutch controlling plunger (38 spring pressed in one direction and mounted in a socket on the beam 12 and in the path of movement of the table 28, and as shown in Figure 7 of the drawings.

in the operation of the mechanism. the

. .n the position shown in Figures and 2.,

7 1O w res are in place with the mass sop n'i.. "2r1al between them, the hand lever 25 will be swung to the left to the posilill) tion shown in Figures 3 and 4. This movement, aided by the mechanism hereinbetore described, will operate the slide 23 and jaw clamping levers 19 to close the chuck aws l7, and simultaneously, through the operation of the rod 39, the jaws 3l-35 on the tail stock will be forced into contact with the wires to secure them to said tail stock, the wires just before this operation having been closed together in any desired manner, and especially by the fingers ot' the operator. The treadle 31 being now depressed the table 23 will be lowered out of the path of the mop material during the twisting operation, and in its downward movement the table will strike the plunger 68, thereby depressing it and swingmg the lever 6! to move the detent 66 away from the lever no. This will permit the spring on the rod 3 to move said rod to the left from the position shown in Figures 1, 5, (l and 7, thereby swinging the end of the lever (35 into the path of movement of the controlling rod Ga. This movement of the rod 63 also operates to swing the disengaging lever 58, connccted with the rod as hereinbetore described from under the nose 5"? oi the clutch actuator 53, thereby perimtting the springs 55 to act upon the clutch member 50 and the actuator 53 to move the rollers 51 into the narrow part of the wedge shaped space, there by connecting the clutch members to effect rotation of the spu le 15 and parts including the jaws 17 carried thereby. The twistingof the wires causes them to be shortened thereby moving the tail stool: 33 toward the head stock and pushingthe rod '64: toward and into contact with the lever 65 that at once starts to return as soon as the twisting operation begins being swung on its pivot to the position shown in Figure 6, 'lhis operat on t the rod (33 against the tQflSlOiI of its spring to the position shown in Figures 1, 3 o 'i', and 12 of the drawings, therew, mov

i J the clutch actuating mechan i into the position shown in said. figures whereby the end of the lever is placed in the path olmovement of the The rotation of the spindle continu until the operation ust described takes place, after which, soon as the spindle completes its rotation, the nose striking said lever will reverse the action of he clutch parts hereinbefore described and the clutch members will be disengaged the rotation of the spindle will cease. The treadle 31 having been released the detent {36 is located in the path of movement of the lever 65 to retain the parts in these PGSltlOBS, and the hold of the chuck jaws being released by operation of the lllllld lever 25, the tail stool: will. move back unoer the pull of the weight ellin readiness for a repetition o't'the operation.

It is essential. in the operation oi": the ma chine that the clutch jaws l? op with the slot or space between them positioned verand tically so that the wires may be dropped into said slots. The chuck jaws will be in such proper position when the nose 57 of the actuator 53 is in contact with the lever 58. However, when in this position the tendency of the twisted wires to untwist to some extent will influence backward movement of the clutch member 50 and thereby return movement of the rollers into the narrow part of the space occupied by them, whereas it is essential that the rollers shall remain in the wide part of said space until the next operation to connect the clutch members.

Owing to the rapid movement of the actuator 53 there is a tendency when the nose 57 strikes the end of the lever 58 for the actuator to bound backwardly and thus move the slot between the jaws from its vertical position. There is, therefore, provided, a detent mechanism to prevent any backward movement of said parts either by bounding or by influence oi the wires to untwist, this mechanism con'iprising a detent plate 69 mounted on the clutch member 50 and held against rotation as by pinning to an upri 'ht ll of the bracket 13. Detent rollers are located in wedge shaped recesses in the plate 69, as shown in Figure 15 or the drawings, and are engaged by spring pressed plungers 'l'l tending to force said rollers into the wider parts of said recesse Vi hen the nose strikes the end of the lever 53 any tendency of the actuator to bound or otherwise move backwa rdly under influence oi the twisted wire to move the clutch member 50 bacltwardly will at once be resisted by the 'detent rollers, and they will immediately, by reason of such action be moved into the narrow part of the recesses,

and such backward movem it of either of said members will be immediately checked.

t will be noted that the connection between the lever 58 and the rod 63 is such that when the arm 60 and finger 62 are swung so that their pivotal connecting point passes a line extending through the center of: their pivotal supports the action of the spring pressed plunger will cause the arm 60 and linger 62 to be moved quick y, the engagement of the end of the finger 62 inthe enlarged socket in the rod 63 permitting this accelerated movement.

lV hen the tail stock 33 is moved back, af-

ter a twisting operation to secure material between wires, and to its rearward position, as herembelore described, it is held against forward movement until the twisting mechtioned for engagement by a flange 73 on the rod 30 when the table 28 is moved downward,

this engagement of the-latch by said flange removing the opposite end of the latch from the path of the tail stock and allowing the latter to move forward under the influence of the shortening wires in the twisting operation, as hereinbefore described.
