Figures 14 and 15 are views similar to Figures 11 to 13, but of a portion only of the mechanism shown in said figures, the scale of Figures 11 to 15 is the same as that of Figures 1 and 2.

My improved mechanism relates more especially to machines for twisting mop material between wires during the operation wherein a continuous length of said material is fed to the wires previous to twisting, said mechanism providing means Jfor cutting off vthe ends of said material after they are placed between the wires and previous to the twisting operation. In the construction illustrated in the drawings herein certain parts are shown but are not described, as they are not a part of the present invention, `and yet they are included in the machine structure as a whole, which machine forms the subject matter for diiferent inventions that are specifically set forth, de scribed and claimed in my copending applications filed concurrently herewith of Serial Numbers, respectively, 120,357, 120,358 and 120,359, and identified as Cases I, II and III and to which reference is hereby made for an understanding of such parts as are not included in the invention of this application. y

VIn the accompanying drawings the numeral 10 denotes end parts of the machine trame that may be supported in any suitable manner, as upon a base 11,V and risingtherefrom, and as shown more speciiically in my said copending applications, beams 12 and 13 andrails 14 extending between said end parts and being secured thereto in any. suitable manner, the beam 12 being located near the upperpart and the beam 13 being secured on'top of said ends.

A twisting spindle is rotatably mounted in bearings in uprights 15 from a bracket mounted on the beam 12, said spindle having a driving pulley 16, and a chuck 17 for receiving and twisting said wires, said chuck being operated as by means of a chuck actuating collar 18 engaged with chuck actuating levers 19 pivotally mounted on a chuck lever support 2O connected with a chuck actuating sleeve within the spindle in a manner that will be readily understood, and comprising' parts which are more specifically shown in my copending applications, further illustration and description of such parts bei-ng omitted herein as not bei-ng comprised in the presen-t invention.

Mop material 2l is fed from any suitable source, this material comprising threads of indefinite length, and the feed of said material being controlled by feed rolls 22-23 supported on shafts 24-25 mounted in the ends 10 and driven by a suitable connection, not herein specifically shown, with other parts of the machine. A tail stock 2G havng clamping jaws 27 is mounted at the opposite end of the machine from the spindle, said jaws being adapted to hold the wires while the spindle is in operation to twist `them. A slide supporting the lingers eX- ended into a groove in the collar 18 may be operated as by means of a handle 28 pivotally mounted on the bracket hereinbefore mentioned and having a toothed engagement with said slide, and a spindle controlling lever 29 operates to control the twisting opferations of the spindle by connections not specifically shown herein but which are fully illustrated and described in my hereinbefore mentioned copending applications. The clamping jaws 27 are operated as by means of a hand lever 30 secured to a shaft 3l mounted in the tail stock and operatively connected with said jaws, said tail stock being slidably mounted on the beam 12. During each cycle of operati-on of the machine the feed of the rolls 22-23 is stopped in a manner shown in my copending applications, this pause being for such time as to permit cutting off of material and the t twisting operation to take place.

Cutting of mechanism In the operation of the machine wires are placed upon a table 32 having a groove 33,

a wire being placed in said groove, after Y which a definite length of mop material 21 is projected across said wire. Said material extends between the rolls 22-23 and underneath the roll 22 from which it is directed by an apron 34 to and upon the table 32.

immediately after the material has been projected across a wire in the groove 33 another plications hereinbefore mentioned.

the wheels or rollers 3G on the rails.

To effect this cutting operation a carriage 35 is supported by grooved rollers 36 travel.- ing on the rails 14, there also being a guide roller 37 engaging underneath one of the rails as shown in Figures 5 and 6 to hold A cutter supporting table 38 is pivotally mounted on a pin comprising a pivot 39 extending between the side parts of the carriage, and an adjusting screw 40 engaging a screw threaded block 41 pivotally mounted between the side parts of the carriage is attached to the table 38 as a means for adjusting its elevation to present a cutter to be hereinafter descril'led in proper position to effect its purpose. A guide 42, in the form of a projector from the under side of the table, is in close contact with the inner facing surfaces of the side parts of the carriage to guide the table when it is moved for adjusting purposes, and also to prevent clamping action when the table is so moved.

A motor 43 is mounted on the table 38 and a cutter 44 is rotatably mounted and driven by the motor in any ordinary manner. In the structure herein shown grinders 45 may be located in contact with the edge of the cutter for sharpening purposes, these grinders being driven from the motor in any ordinary manner.

In operation the cutter 44, that is continuously driven by the motor, is passed across the mass 21 of mop material in one direction only to sever the ends of the mass, and after said ends have been twisted between wires and the twisted structure removed the cutter is passed in the opposite direction to again sever the ends of the material preparatory to another twisting operation, that is, the ends of the mass are severed at each pass of the cutter across .said mass, and this reciprocating movement of the cutter is obtained by means of a chain 46, or equivalent device, secured at its opposite ends to eyes on the cutter carriage and passing around sprockets 47-48 rotatably mounted on the ends 10 of the frame, a shaft 49 having the sprocket 47 secured thereto being power driven as by means of a bevel pinion 50 meshing with bevel gears .6l-52 loosely mounted on the shaft 49 and adapted to be operatively connected with said shaft by means of a clutch member or Collar 53 splined to the shaft and having clutch teeth to engage with clutch teeth on the gears 51-52, as shown in Figure 10 of the drawings. The pinion 50 secured to a short shaft to be hereinafter described. The collar 53 is shifted on the shaft 49 as by means of a clutch lever 54 secured to a short shaft 55 mounted in a bracket 56 secured to an end 10 of the frame, and as shown in Figures 8 and 9 of thc drawings. The shaft 55 has a bevel pinion in mesh with a bevel pinion 57 secured to a clutch actuating shaft 58 mounted in an end 10 ofthe frame, and as shown in Figures 8, 9 and 10 of the drawings.` A clutch actuating lever 59 is secured to the shaft 58 and has a handle at its upper end conveniently accessible to the operator of the machine, as shown in Figure 3 of the drawings.

This handle 60 is attached to the lever 59 so that it may be moved out and in to enter a controlling pin 61 in and remove it from slots in clutch positioning collars .62 on a rod 63, said handle and pin having a spring (not shown) for moving the pin into said slots. These slots are formed substantially on the arc of a circle having the Vpivot of the lever 59 for its center. A centering collar 64 is slidably mounted on the rod 63 between the positioning collars 62, said collar 64 having a stop flange tolimit movement of the pin 61 and consequently the lever 59 and clutch member 53. The collars 62 have recesses to receive the collar 64 on opposite sides of its flange. These collars constitute means for indicating the direction in which the handle 59 should be moved to effect engagement of the clutch members to start operation of the cutter and in a manner as follows: When the pin 61 is in a recess in a collar 62 the clutch mem-v ber 53 will be engaged with a gear 51 or 52 to cause the sprocket 47 to rotate and move the carriage 35 in a direction corresponding with the direction of movement of the lever 59 to locate said pin in said recess. As an example, when the lever 59 is moved from the position shown in Figure 11 to the right to engage the pin 61 in the recess in the collar 62 on the right, andas shown in Figure 12, the carriage will be moved to the right by the resultant operation of the mechanism. As the carriage thus moves from its extreme left position, as denoted by a lug 65 projecting from the bottom of the carriage, and as shown in Figures 11 to 13 of the drawings, and from contact with a shifting collar 66 secured to a shifter rod 67 slidably mounted in the end 10 of the frame, said rod passing through the lug 65, it causes said lug to encounter another shifting collar 68, thereby sliding the rod 67 to the right, and moving a shifting finger 69 into contact with a collar 70 on an auxiliary shifting rod 71 mounted for sliding movement in an end 10 of the frame, and in a block 72 secured to one of the rails 14, Vand as best shown in Figures 9 and 10 of the drawings, This movement of the rod 71 causes clutch actuating fingers 73 secured to the rod 71 to swing a pin 74 secured to and projecting from the shaft 58 to the right, said fingers 73 being substantially in contact with said pin. This rotating movement ef the shaft 58 causes the lever 59 to be swung to the left from the position shown in Figure 12, and to the position shown in Figure 13, this movement of said lever sliding the collar 64 to the left and the flange on said collar stopping the swinging movement of the lever 59 in the position shown in said Figure 13. This movement of the shaft 58 just described swings the arm 54 to the left, as seen in Figure 10, and disengages the clutch member 53 from the gear 52 and placing said clutch member in a neutral position, as shown in Figure 10, thus stopping movement of the cutter mechanism. This operation just described has caused the cutter carriage with the cutter thereon to travel from one end of its path of movement to the opposite end thereof, the cutter passing through the mop material 21 and severing its ends.

To again start the operation of the cutter the handle 59 is swung to the left from the position shown in Figure 13 and the pin 61 is placed in the groove in the left hand collar 62. This causes the clutch member or collar 53 to be engaged with the gear 51 whereupon a reverse movement of the cutter carriage and the cutter thereon takes place, the cutter in this reverse movement again severing another length of material from the end of the mass 21. It will be understood that each time an end of said material is cut off it is immediately twisted between the wires and the twisted structure is removed before the lever 59 is again operated to start the mechanism. In this reverse movement of the cutter carriage the finger 69 strikes a collar 75 secured to the rod 71, thereby shifting said rod and effecting disengagement of the clutch member or collar 53 lfrom the gear 51, placing the former again in a neutral position and stopping operation of the cutter mechanism. As the rod 71 is thus shifted the lever 59 is moved to the right from the position shown in Figure 15 and to the position shown in Figure 11, this being the position of the parts at the time this description of the operation started. In order to permitrthe cutter carriage to have its full movement before disengagement of the clutch 53 it is desirable that the carriage be allowed to effect a part of its movement before movement of the shifting rod starts, and to this end spring. pressed rod holding latches 76-477 are pivotally mounted on one of the rails 14, and as shown in Figure 8 of the drawings, and are adapted to engage the collars 66 and 68 respectively to temporarily hold the rod from movement during the first part of movement of the carriage and the motor with the lug 65 thereon. Each of the latches is provided with a releasing cam 78 located in the path of movement of the lug 65 and thereby actuated, after the lug has moved a certain distance, to release the latch 66 from the collar 68 leaving the rod 67 free to be moved at the proper time.

As lhereinbefore mentioned the bevel pinion is secured to -a short shaft, this shai't 79 being mounted in a Abearing in one of the ends 10 of the iframe, and as shown in Figure 9 of the draw-ings, said `shaft having a pulley 8O secured thereto and driven as by means of a belt l81 extending to a pulley 82 connected with and driven from the spindle hereinbefore referred to and to which spindle the pulley 16 `is secured.

Clamping mecha/neem As an aid -to the cutting mechanism in severing ends of the mop material from the mass 21 a clamping device to hold the'ends of said material is provided, this comprising a clamping bar 83 supported at its ends on arms 8st pivotally lmounted on the ends 10 'of the frame, one of said arms having 1a gear or segment 85 in mesh with a similar gear or segment 8G rigidly connected with -a clamp operating lever 87 extending` downwardly and having its end Agrooved to receive the rod V67, and as shown in Figures 4, and A11 -to 13 of the drawings. The 'arm 84 at the opposite end of the bar 83 has its pivotal support 88 rioidly connected 'with a 'clamp operating lever 89 formed similarity to the lever 87 and acting in the same manner to raise the bar v83 `from clamping position, the lever 87 being engaged by a clamp actuating collar 90 on the rod 67, and the lever 89 being engaged by a clamp actuating collar 91 on said rod as it lis shifted one way or the other in the manner as hereinbefore described which movements of said clamp operating levers lifts the vclamping bar 83 and releases the mass 21.

The bar 83 is preferably formed of 'two strips of material sp'aced apart for the recepti'on of 'the 'edge of the cutter between them, and as shown in Figure 5 `'of the 'drawings. lSaid `bar is pressed downwardly into clamping position as by means of spring pressed plungers "92 located in recesses in the beam 13, fand as shown in Figure 2 of the drawings, it being observed lthat the pressure of these springs acting 'eventually against the collars 66 and 68 would move the lug G5 and hence the carriage from which said Alug projects, fand the latches 7G-77 prevent such movement by 'holding the collars 66 `and G8 Vwhile the carriage is at rest.

In accordance with the provisions `ot the patent statutes I have described the principles or' (operation of my invention, *together with the device which I now consider to represent the best kembodiment thereof; but I desire to have it understood that the device shown "is only illustrative, and that the invention may be'carried out by other 'means and applied to uses other than those Iabove set Iout.
