BAND AND CORD TWlSTlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 426,383,dated April 22, 1890..

Application filed February 16, 1889. Serial No. 300,070. (No model.)

To all whom it may concern:

Be it known that I, J OHN L. INMAN, a citizen of the United States, residing at Putnam, in the county of lVindham, State of Connect-icut, have invented certain new and useful Improvements in Band and Cord Twisting Machines, of which the following is a specification, reference being had. therein to the accompanying drawings.

The object of my invention is to provide a machine whereby all the steps in the twisting and doubling of cord, from the supply of the parallel strands to the removal from the twisting-jaws, are performed automatically by the same machine, and without the intervention of intelligent guidance during the operation.

My machine is more particularly designed for making loop-bands for rope-pulleys; but

of course I donot limit myself to this use ofthe machine, as it is evident that any form of cord can be made by it without the change even of details.

In the drawings, Figure l is a perspective of the working end of my machine, showing the tracks broken near the forward end of the same. Fig. 2 is a perspective of the holding end of my machine, showing a portion of the other ends of the tracks. Fig. 3 is a side View of a portion of my machine with the feed-funnel, the front counter-shaft and the rear shaft and removing-shaft not shown. Fig. 4 is a top view or plan of a portion of my machine with the cam-shaft and feed-funnel removed. Fig. 5 is a rear view of a portion of my machine, illustrating the reversinggear attached to the driving-pulley of my holding mechanism. Fig. 6 is a detail of the gearing used for transmitting the power of the rear shaft to the driving-pulley and to the cam-shaft, said figure showing said details from the front, with all mechanism forward of said gear removed. Fig. 7 is a detail of the beveled brake, seen from the rear, and Showing its connection with the cam that operates it on the cam-shaft. Fig. 8 is a side view of my machine from the opposite side from that shown in Fig. 3, showing the rear shaft, together with the shifting mechanism and the rear notched gear and lover. Fig. 9 is a front view of a portion of my machine,

only showing the revolving gear and the removing device, together with the feed-funnel and its reversing-gear. Fig. 10 is a side View from the direction of the removing-shaft of the twisting-jaws and the position of the feed-funnel with regard to said jaws when in operation. Fig. 11 is a top view of the forward portion of the power-shaft, showing the details of the twisting and doubling mechan- 6o ism in central horizontal section. Fig. 12 is a detail of the circular cam and its operating mechanism as seen from the forward part of the machine. Fig. 13 is a detail of the clutch between the independent sections of the rear shaft, showing the pulleys in section. Fig. 14 is a top view of the removing-fingers at the moment when they close upon the completed cord. Fig. 15 shows a detail of the reversing-arm and of the cam operating it. Fig. 16 shows the detail of the notched gear on the power-shaft, the lever controlling the same, and the cam operating said lever. Fig. 17 is a side elevation of my preferred form of clutch between the two rear shafts.

The power whereby my machine is operated is applied thereto by means of belts running upon two shafts A and B, termed, respectively, the rear shaft and the powershaft. Each of these shafts is provided with two pulleysthe loose pulley B and the tight pulley 13 upon the power-shaft and the constant pulley A on the constant drivingshaft or constantly-moving section of the rear shaft and the intermittent pulley A on the twisting-shaft or intermittently moving section of said rear shaft. These two sections of the rear shaft come together between the two pulleys, as shown in Fig. 13, where they are provided with clutches, which are operated by means hereinafter described. The intermittent section is the forward one, and, as shown in Fig. 4, is provided with the following parts:

Just forward of the intermittent pulley is the gear A This is a smooth wheel having a notch in its periphery, which is intended for cooperation with a lever, as hereinafter described. Forward of this gearis the smooth friction-wheel A, which is intended for co- I00 operation with the beveled brake 13 On the end of the shaft and beyond the bearing, as

shown in Fig. 4, is the gear-wheel A employed in the operation of the outside and inside gear on the end of the power-shaft.

The constant section of the shaft is situated back of the interposed clutches and bears the following parts: Next to the pulley A is the spur-gear A, for use with the intermediate gear, hereinafter described. Just back of this gear is the worm A the rear side of which abuts against the back bearing of the rear shaft, as shown, Fig. 4:. This worm is employed for the purpose of running the transmitting-shaft, so called because it carries the power of the rear shaft to the camshaft O, to the secondary cam-shaft F, and to the vertical shaft G. This transmitting-shaft is shown best in Figs. 5' and 6 at H. In these two figures this shaft is seen from opposite sides, and in Fig. 6 the end bevel-gear H is left out. This bevel-gear is on the inner end of the shaft H and is geared with. the bevel-gear E on the end of the shaft E, which operates the removing parts of the machine. Next to this gear comes the worm-wheel H which gears with the worm A and through which the power is imparted to the transmitting-shaft. Between the two middle bearings, as shown in Fig. 6, comes the transmitting-worm H and beyond the outerbearing, as shown inFig. 5, is placed the bevel H, which operates the carryingavheels, as here inafter described. Meshing with the worm H is the worm-wheel F back of the frame of the machine and mounted rigidly upon the secondary worm-shaft F. WVithin the frame and mounted upon the front end of said shaft F is the spur-wheel H which gears with the corresponding spur-wheel on the end of the cam-shaft O, as shown at Upon this camshaft C are mounted eight cams, as follows: 0 the cam that operates the lever going to the notched gear on the; front shaft; 0 this and cam C are alike, save that they are different-ly placed with regard to the shaft, and they are both used for the operation of beltshifters, as hereinafter described; 0 the cam that operates the lever to the notched gear on the rear shaft; C the cam operating the beveled brake, as shown in Fig. 3; G the cam operating the pin and lever for raising the rack on the feed-funnel carriage, as hereinafter described; C the cam operating the circular cam on the power-shaft for closing the holding-jaws, and O the cam operating the cutter 0r shears, as shown.

B is called the power-shaft because, although the main power is not applied di rectly to it, the power which is applied thereto is that which accomplishes the main function of the machinethat.is to say, the doubling of the cord. As seen clearly in Fig. 4, this shaft is operated independently of the other shafts, save for the interposition occasionally of the intermediate gear, as hereinafter described. The parts operated by this shaft and rigidly mounted thereon are as follows: Farthest to the rear is the crown- B, a collar B and a nut 13 gear B which has a portion of its teeth cut away, which is used in connection with the intermediate gear heretofore alluded to. B is a notched gear coming just forward of said crown-wheel and used, as before mentioned, in connection with the cam O and a lever operated thereby. Farther forward are placed the pulleys B and B and then the beveled brake B employed in connection with the cam O and the friction-wheel A on the rear shaft, for a purpose hereinafter described. On the end of this shaft (see Fig. 11) is the revolving head B and between this revolving head and the beveled brake is placed the circular cam B, which turns loosely on the shaft B, for the purpose hereinafter described. Two holes are made in the revolving head, which holes are placed diametrically opposite one another, and through which are inserted the spindle-cases B These cases are hollow, as shown, and are provided with a narrow waist portion, which projects through the holes in the revolving head, and with widened parts acting as flanges on the inner and outer faces of said head. On the front faces of these cases are placed the flanges 13*, which may be made either integral with or separate from the rest of the spindle-cases. Through these spindle-cases and through the slots 13 in the circular cam B project the spindles B and around said spindles are wound the spiral springs B Fig. 11. These springs tend to keep the spindles forced outward, as shown in the case of the upper spindle in Fig. 11.

The enlarged portion B of the spindlecases is a gear, and is provided with a square perforation, through which extends a square portion of the spindles. Outside of this revolving head and its auxiliary devices is placed the outside and inside gear J. (See Fig. 9.) The outside teeth of this gear mesh with the wheel A and the inside teeth with the gears B On the outer end of each spindle is pivoted a pair of jaws B hinged by means of links B to the flange B and provided with a square shank fitting into the square perforation in the gear 13 when the spindle is drawn back, as shown in the lower spindle in Fig. 11. The rear end of each spindle, after passing through the circular cam, through the curved slots B as shown in Fig. 12, is provided with a beveled head The beveled head has an undercut bevel and straddles the spindle as it emerges through the slot B Fig. 12 shows the circular cam from the front, and in dotted lines therein are shown the curved cams B and B One of these is longer than the other, as shown,and both extend along either side of the curved slots B As indicated in dotted lines, these cam-slides have beveled ends which correspond to the undercut bevels in the shoes on the ends of the spindles, and when the cam is turned in the direction indicated by the arrow in Fig. 12 these slides are projected under the shoes of each spindle successively, thus forcingthe ter-shaft is fixed the wheel D on which is mounted the side projecting pin D In Fig. 8 may be seen the horizontal pin K. On this pin is mounted the arm K, Fig. 12, provided with the pivoted spring-pressed arm K and the rigid downwardly-extending arm K This arm K overlies the cam C on the camshaft C and is provided with a pin K intended for occasional engagement with the pins 0 and C on the surface of the cam C The springpressed arm K is pivoted, as shown, to the end of the arm K. Motion in one direction is prevented by means of the stop K and in the other direction such motion can only take place against the action of the spring K. This spring is for the purpose of keeping the arm K up against the edge of the circular cam B and to allow of the sliding of the said ar'm K over the notches shown on the edge of said circular cam. The operation of these various parts will then be as follows: As the cam C revolves in the direction shown by the arrow it catches 011 the tooth K on the arm K and raises said arm until the foot of the arm K is thrust out into the path of the pin D on the revolving Wheel D on the shaft D. This wheel revolves in the direction of the arrow and turns with greater velocity than does the cam C As the pin comes up under the arm K? the whole piece K is thrust upward, forcing the arm K into the notch B in such a manner as to cause the circular cam B to turn through a portion of a revolution in the direction of the arrow. Hitherto the end of the sliding cam B had been just touching the edge of the shoe 011 one of the spindles B -namely, the lower one. (Shown in Fig.11.) This movement-,however, causes the sliding cam to raise the shoe on the end of said spindle, as heretofore eX- plained, and to bring said spindle into the position shown in the case of the lower spindle in Fig. 11. The spindle being thus raised or pulledbackward drags the jaws B after it and draws the square shank of said spindlejaws after itinto the aperture in the gear B The links B also conspire to prepare the jaws for entrance into said aperture by their squeezing action and the shortening of the distance between their ends incident to their pivotal attachment to the flanges and the inward movement of the j aws. This dragging been closed, there is an appreciable halt, and

then the slowly-moving cam C again catches the pin K this time by means of the pin or tooth C and the above-described operation is repeated. This time the shorter sliding cam 13 is in turn thrust under the shoe on the other spindle, and the other pair of jaws is shut with a snap. Of course it must be understood that the arm K is in contact with the edge of the circular cam only when the arm K is raised by the tooth on the cam C The holding portion of my machine consists of a carriage a, borne on wheels I), running on the tracks 1 and 2, which are placed under the base of the working portion and extend to any length, according to the length of cord to be wound at once, and onsaid carriage is borne a standard 0, carrying a hook (Z, pivoted to said standard at e. An endless cord passes around the carrying-wheels 3 and at and is attached at one point to the bottom of the carriage a. By the running of this cord over these carrying-wheels one way or the other the carriage is brought toward or carried away from the working part, .as described farther on. This movement of the cord and corresponding revolution of the earrying-wheels in one direction or the other is accomplished as follows: The vertical shaft Gr receives its motion from the transmittingshaft by means of the gears 11* and G. At the bottom of the shaft G is fixed the wheel G turning in the directionindicated by the arrow, and meshing with said gear-wheel G are the two bevel-gears G and G turning necessarily in opposite directions. These bevel-gears turn loosely upon the shaft of the carrying-wheel 3. A clutch provided with teeth G is arranged to slide on said shaft of the carrying-wheel and is kept from turning on said shaft by a feather or other analogous means.

The secondary camshaft F, Figs. 3 and 4, bears at its outer end two cams F and F The latter is for a purpose hereinafter described, and the former is employed in operat ing the reversing-shaft, as follows: The cam F has two flanges in the planes of itsfaces, said flanges having projections F and F turned inward and so beveled with regard to the direction. of the revolution of said cam (shownby the arrow in Fig. at) as to cause the backward and forward movement of the lever L, fixed by screws or other means to the reversing-shaft L. This cam F turns, of course, very slowly by means of the action of the worm 1-1 on the worm-wheel F. As seen by comparing Figs. at. and 8, there are two sets of these oppositely-arranged teeth for the purpose of the revolving of the reversingshaft, one set acting to turn the lever so as to run the carrying-wheels in a positive direction and drive the carriage away from the working portion of the machine, and then setting it back into a neutral position as soon as said carriage has reached the end of the track, and the other set of teeth acting to IIO move the reversing-shaft all the way in the contrary direction and bring the I carriage back to the working portion, bringing the lever into a neutral position again as soon as the carriage reaches the near end of the track again.

The reversing-shaft is borne in the bearings 8 and 9, Fig. 5, and is adapted to turn in said bearings, said turning being accomplished by means of the shifting of the lever L by means of the beveled teeth on the inside of the flanges of the cam F The clutch G is borne on the end of a lever similar to the lever L, but set at the end of the shaft L, as shown at L According as the shaft is turned in one direction or the other, said clutch is thrown into gear with one or the other of the gears G and G which are turning in opposite directions, and,since the clutch can only slide and cannot turn on the shaft ofthe carrying-wheel, said shaft and said wheel is carried in the direction required, according to which gear-wheel it is brought into gear with. Thus the movement of the carriage a is controlled by the slowly-revolvin g cam F and said cam is placed in such a position upon its shaft as to make the proper movements of said carriage occur at the proper time. About midway between the ends of the reversing-shaft is fixed the arm or lever L the end of which is attached to the end of the track 1, as shown in Fig. 5, and said track 1 is arranged to slide within its bearings by the action of this arm L at the proper time, and for a purpose hereinafter described.

Returning to Fig. 2, it willbe seen that the end of the hook d is embraced by a turned end of the top of the standard 0, which I call a scraper, as it is used for the purpose of scraping against the outer edge of said hook for the purpose of removing the cord at the proper time, as will be shown. The depending end d of the hook is held toward the vertical position by means of the spring (1 in order to counterbalance the weight of the horizontal hook-arm proper and to allow of the springing of this arm past the trip 10. The tip of the hook projects, as shown, up past the scraper, and is intended for the holding of the middle of the cord in the process of twisting and doubling. On the inner side of the standard 0 is fixed a pin or other support g, over which extends and upon which weighs the brake 11, which is preferably a metal bar pivoted to the track 1 or to a sleeve upon it, as at 12. This brake is for the purpose of retaining the carriage in its proper position during the operation of doubling, when by the shortening of the cord incident to this operation said carriage would tend to be dragged unduly near the working portion of the machine, and thus cause a slackening of the cord, which would end in the tangling of the cord and destruction of the work. Any form of brake would answer in this connection; but I prefer this form, as it is very simple and co-operates naturally with the track 1 for its undoing. here, in anticipation of the description of the mode of operation of my machine, that just as the operation of doubling is completed the carriage is found near the end of the lever 11, having been carried there by the gradual shortening of the cord incident to its doubling.

Fig. 16 shows a detail of the cam C and the notched gear B and their mode of co-operation by means of the bell-lever H. Said bell-lever is pivoted at the point M and is composed of two arms--M horizontal, and M, vertical. The arm M rests at one end upon the cam C and is kept in contact therewith by the action of a spring M attached to the frame of the machine. The other arm M is provided with a projection which enters a corresponding notch 13 in the periphery of the gear B on the power-shaft to which it is fixed. As shown in. Fig. 16, said projection is on the point of being removed from the notch on the gear B and itis evident that it only remains therein during the contact with the end of the arm M of that portion of the periphery of the cam C which is included between the dropping-point 0 and the point shown in contact on the figure; hence during the greater part of the time said projection on the arm'M is out of the notch 3 During this time the power-shaft is revolving.

Fig. 15 shows a detail of the shifter for the front belt, which is managed by means of a cam C, turning in the direction shown in the drawings, this figure being seen from the direction of the front of the machine. The arm N is pivoted to the frame of the machineat N, and has a pin, which is shown at N and is made to continually bear against the side of .the cam C by means of a spring or otherwise, according to the fancy of the builder, as this is a matter of mere mechanical skill.

It may be'as well to state The bearing of thinner or thicker portions of the cam against this pin throws the arm to one side or the other, and the top of said arm is made in the same form as the shifter on the back shaft, as shown at Oin Fig.8. This looped portion of the arm embraces the strap or belt that runs the power-shaft and causes it to follow its movement onto one pulley or the other.

In the case of the shifter on the rear shaft the cam 0 that operates it is of the same character as that which operates the shifter on the front or power shaft; but there are de tails necessarily added to this shifter, as follows: The shifting-arm O is pivoted to the frame at 0 near which point of pivoting there branches out from the main standard shifted by the arm 0 from the constant pulley to the intermittent pulley the pin 0 will strike against the end of the arm 0 and turn the bell-crank, so as to push'the arm 0 against the disk P, Fig. 13, and as this disk is made so to slide upon the shaft A at will the disk acts by means of the pins P to thrust the clutch P into gear with the clutch P on the end of the constantly-moving section of the shaft A. Now, as the belt is constantly moving so as to revolve this clutch in the direction indicated by the arrow, the square ends of the teeth on the clutch P will act against the square ends of those on the other clutch, and consequently the two pulleys A and A will become practically one, and the shifting of the belt will cause no interruption of the motion of the constantly-moving section of the shaft A. trary, the belt is shifted onto the pulley A, the power continuing to act in the direction of the arrow, the beveled sides of the teeth -on the clutch P will act on the correspondingly-beveled sides of the teeth on the clutch P and. the consequence will be the automatic throwing apart of the clutches and the consequent replacing of the disk in position for the renewed action just described. All these movements then are regulated by the cam 0 which directs the action of the shifter on the rear shaft, and it is the setting of this cam that settles the accuracy and timeliness of the movement.

Figs. 1, 3, 9, and show the details of the feed mechanism whereby the rovings or parallel strands are placed in position automatically by the action of the carrying-wheel and appropriate cams and gears. The standard Q, of the feed-carriage supports a horizontal funnel Q, which is set in the plane of the jaws when in their normal position, and so near to them' as to pass between them when moved in a horizontal line before them as guided by the tracks between which the carriage moves. The bottom of this carriage is contained between the sides of the casing 13, which is grooved, as shown in Fig. 3, and which acts to guide said carriage in its aforesaid movement before the jaws. The funnel Q is hollow and is of the proper diameter to allow of the passage of the roviugs or strands with the proper amount of friction, said rov ings projecting beyond the end of the funnel a distance of the width of the jaws B To the bottom of the carriage is pivoted a rack, as shown in Fig. 9 at Q This rack is normally in a drooping position, and is only held in an approximately horizontal position by the bottom of the casing 13. WVhen the carriage is in its forward position, as shown in Fig. 9, this drooping of the rack is particularly marked, as there is less of it resting on the bottom of the guide.

Underneath the frame of the machine is a' lever B, pivoted at R and bearing at one end a pin R, which passes up through a sleeve 14 on the frame-work and bearing against the periphery of a cam 0" on the hen, on the con-,

cam-shaft. At the other end of this lever i a pin which passes up through the bottom of the guideway and bears upon the under surface of the rack. By the revolution of the cam with the cam-shaft the pin R is depressed at intervals and the pin R correspondingly raised until the rack is forced up thereby into gear with the broken gear D (shown in Fig. 9) on the end of the countershaft D. This action of the cam is timed to take place just as the teeth on the broken gear come into the position shown in the fig ure, and thus the carriage is carried back, as will be further explained.

Q is a roller on which the drooping end of the rack is allowed to rest when out of gear with the broken gear, as shown in dotted lines in Fig. 9. Then the carriage is in the position shown in Fig. 1, it is held in place against the action of the weight 16 by means of the latch 15, which is adapted to slide up onto the pin g of the holding-carriage. When this latch is so raised by the pin g, the weight 16 is allowed to come into play through the cord 22 over the pulley 16*, and the carriage and funnel are made to slide down the guide into the position shown in Fig. 9. When in due time the pin R raises the rackinto gear with the wheel D the carriage is carried back and the number of teeth upon said wheel D is calculated to just carry it back into the power of the latch 15, at which time the smooth part of the wheel comes over the rackand there is no further action.

As seen in Fig. 1.1,the beveled brake B is lined with leather and rides loosely upon the shaft 13. It is so formed as to fit the outside beveled conical surface of the circular cam and to act as a brake upon its rotation in case of need. In Fig. 3, as also in Fig. 7,-is shown the friction-shaft S. At the bottom of this shaft is a spiral spring or other device for the purpose of turning the shaft in such and thus permits the arm S to act and throw the beveled brake against the top of the circular cam by the action of the spring S. \Vhen this action has been snfiiciently prolonged, the inclined side of the cam comes into play and the arm S is pushed slowly out of the notch in the cam and the beveled brake is cleared of the cam. A spring S interposed between the arm S and a projection S on the beveled brake, tends to turn said beveled brake against the direction of the arrow. A pin S is placed on the back of the beveled brake in such a position as to properly limit this tendency of the spring 8, and the two keep the beak S normally out of contact rith the friction-wheel A. This beak is an integral part of the beveled brake, and is coated, preferably, with leather on its under side in order to oppose a considerable friction to the wheel A Turning to Fig. 5, we see a back view of the machine and a detail of the action of the back cam F This cam turns with the secondary shaft, on which it is mounted, in the direction of the arrow, and upon it rides a hooked arm T. Upon a pivot T extending through a portion of the back part of the frame, is fixed the stud-plate T, having two bearings upon it for the sets of gears shown in the figure. These gears are the spur-wheel T destined for gearing with the spur-wheel A, Figs. l, 5, and 6, the spur-wheel T gearing constantly With the spur-wheel T, and the pinion T on the same bearing with the spur-wheel T and meshing with the spur-wheel B on the powershaft. On the other end of the pivot T is the arm T, which is fixed thereto, and which by means of the constant bearing of its end upon the cam F keeps the stud-plate swung up into such a position as to hold the gears it bears out of mesh with the spur-wheels B and A. This set of wheels on the stud-plate is then called the intermediate gear, as it is intermediate between the rear shaft, to which constant power is attached, and the powershaft. Its purpose will be explained farther on. Of course, as the notch is brought around until it comes under the end of the arm T, said end drops into it, and the intermediate gear is allowed to connect the rear shaft and the power-shaft, as specified. At the proper time the inclined face of said notch lifts said arm T out of said notch and the gear is again free. The shaft E, which is run by means of the bevel-gear E, bears at its other end a small spur-wheel E, which gears with another spur-wheel E which runs the remover, as will be explained farther on.

The cam C operates in all respects in the same manner as the cam C save that the notched gear with which it is connected is situated on the rear shaft, as shown in Fig. 8 at'A where also the connecting-lever is shown at 0 The purpose of this lever and notched gear is analogous to that of the notched gear and lever on the front shaft, as will be further explained.

The cam C is shown in small detail on the left of Fig. 3, and is used for operating the cutting mechanism. tions U and U the latter being fixed to the frame of the machine and the former being movable and pivoted at U. The inner end of the portion U extends within the frame of the machine back of the pivot, and its end rests upon the top of the cam 0", against which it is constantly held by means of the spring U or its equivalent. The inner edge of the portion U and the outer edge of the portion U are sharpened in order to admit of the cutting of the cord at the proper moment. This operation is brought about by the arrival of This consists of two porof the cam is made to come under the armU I of the cutter the spring U thrusts said arm downward upon the cam and the cutting action is complete, since the cutters are thus brought into contact.

The operation of the machine will then be asfollows: Taking the machine at the moment when a cord has just been completed, the belt on the rear shaft is on the constant pulley and the shafts F, G, H, and D are in motion, the cam F being on the point of thrusting the lever L toward the right in Fig. 4 and bringing the clutch G Fig. 5, into gear with the bevel-gear G The jaws, funnel, &c.,are in the position shown in Fig. 1. At this moment the projection F on the cam F Fig. 4, comes against the lever L and thrusts it to the right, throwing the clutch G6 into gear with the bevel-gear G. As seen by the direction of the arrow on this gear, the carrying-wheel 3 is thus made to revolve in the direction opposite to that of said wheel in the figure, as shown by the arrow on said wheel. This wheel carries the endless cord with it, and the effect of this rotation is to bring the holding mechanism toward the working part of the machine. This brings the hook d between the jaws 13 and causes the pin g, Fig. 2, to raise the latch 15, Fig. 1. This latch being raised, the funnel-carriage is liberated and the weight 16 brought into operation, thus drawing the funnel forward past and between the two pairs of jaws 13 as plainly shown in Figs. land 10. In this position, as shown in dotted lines in Fig. 9, the rack is depressed and out of gear with the wheel D At this moment another projection 011 the cam F thrusts the lever into a neutral position and the carrying-wheels cease to act on the carriage of the holding mechanism. As the funnel now stands the rovings contained therein proj ect beyond the end of said funnel and stand in a position to be grasped by the right-hand pair of jaws in Fig. 9. At this moment the cam O Figs. 3 and 12, is brought into such a position that the pin C raises the arm K, and by the action of the pin D on thewheel D the right-hand jaw in Fig. 9 is closed with a snap, and the end of the rovings clipped thereby. At this moment the cam C is brought into operation and the pin R thrusts upward, bringing the rack Q into gear with the wheel D on the end of the shaft D, which by this time has just reached the position shown in Fig. 9. The rotation of this shaft returns the funnel to its position in Fig. 1, the rovings therein being drawn therethrough by the holding of the end thereof by the jaws B wheel D have all acted and the carriage is brought back into the position shown in Fig. 1 another projection on the cam F thrusts the lever L in such a direction as to bring the clutch G into gear with the bevel G and the carrying-wheel is made to revolve As soon as the teeth 011 the in the direction of the arrow thereon and the carriage returns to its position in Fig. 2. As it comes back into this position the pin 9 enters underneath the brake-lever 11, which has been brought forward for that purpose by the action of the lever L Fig. 5. Fixed to one of the jaws of the left-hand pair in Fig. 1 and extending through a p erforation in the other jaw is a curved pin 17, between which and the intersection of the jaws the funnel was made to pass, as above specified. The effect of this pin is to retain the rovings, that would otherwise extend from the mouth of the funnel to the hook and thence to the right-hand pair of jaws. Thus these rovings are made instead to extend from one pair of jaws to the hook and thence back to the other pair of jaws. No sooner has the holding-carriage reached its position, as shown in Fig. 2, when the cam-pin O on the cam Fig. 12, reaches the pin K? and the arm K is raised again, with the effect of closing the left-hand pair of jaws on the other end of the rovings which extend therethrough, as above specified. At the next moment the cam 0 brings the drop-notch under the end of the arm U and the spring U causes the cutting of the rovingsbetween the end of the funnel and the left-hand pair of jaws. Il'itherto, as specified, the belt on the rear shafthas been running on the constant pulley; but as soon as this cutting is effected the cam C shifts the belt onto the intermittent pulley, and the clutch between the two pulleys is shot, making the two pulleys practically one, as described above. Thus the action of the cam-shaft is not interrupted. This shifting, however, causes the gear A to revolve, and with it the inside and outside gear on the revolving head B This inside and outside gear J, being driven from the outside itself, drives the gearsB on the spindles by means of the inside gears, and this with a high velocity. These spindles then, carrying the pairs of jaws, remain thus far in the same horizontal plane; but they revolve upon their own axes, and there is a twisting set up in the two sides of the cord between the holdinghook and the jaws. This hardensthe cord in preparation for the doubling process. The .direction of this twisting motion can be plainly seen from inspection of Fig. 9, where the arrows show the revolution of all the gears. As will be seen farther on, the twisting motion must be prolonged far beyond the degree of twist'nccessary in the finally-prepared cord, inasmuch as there is a tendency to undo this twist present during the doubling process. This revolution is, as may be seen, in the same direction in both the spindles. As soon as this twist is completed the cam 0" liberates the lever 0 and at the same moment the shifter C returns the belt on the rear shaft to the constant pulley. The forward part of the rear shaft now revolves only with its own inertia, and the projection on the end of the lever 0 rcstin g against the wheel A Fig. 8,

enters the notch on said wheel and at the proper moment definitely arrests the motion of said rear shaft. This notch is so placed with regard to the gearing of the rear shaft with the gear J that when by its means the rear shaft is stopped the opening lines of each pair of jaws are in the same horizontal plane, the spindles themselves not yet having left said plane. The object of this adjustment of the stoppage of the rear shaft is to insure the opening of the jaws in such a position that the funnel will pass easily between them, the adjustment of said spindles themselves being managed by means of the analogous device B Fig. 3. The belt on the powershaft has hitherto been running upon the loose pulley B, and at this moment the shifter C shifts the belt upon the tight pulley 13 thus setting the power-shaft into motion in the direction of the arrow in Fig. 7. This carries the jaws, and with them the ends of the cords, around one another in a vertical plane of revolution in the same direction as the twisting motion of the inside and outside gear. This doubling of the cord from the hook of the holding mechanism causes a shortening of the cord. and a consequent slow motion of the carriage toward the working mechanism, which motion is controlled by the action of the brake on the pin g. lVhen this doubling action has been carried on sulficiently, the removing-jaws come into play in the following manner: The wheel E Fig. 10, operated as described above, runs on a common shaft with the wheel V, Fig. 9,, which latter is provided with two series of teeth V, consisting of five teeth, and V consisting of three teeth. Just forward of this wheel V is pivoted the shaft V bearin the pinion V and the fixed arm V Figs. 9 and 14.. Pivoted to the arm V a little distance from its point of attachment to the shaft V is the arm V connected with the beak V by the pivot-pin V, Fig. 14:. A spiral spring or its equivalent serves to keep the arm V in the position shown in Fig. 9, which is the position preserved during the actions above noted and described. During these operations, however, the wheel V has been constantly revolving in the direction indicated by the arrows in Fig. 9, and just as the doubling action described above is completed thefirst series of teeth V comes into play against the teeth of the pinion V and raises the arm V into the position shown in Fig. 14,. where the arm V T is shown as forced down upon the arm V by the agency of the beak V which is brought into contact with the spring-guard V for this purpose of thus closing the removing-arms. The length of these arms is such as to bring the completed cord between them,

as shown in Fig. 14, and while in this position the jaws on the revolving head are opened, as will be further described, and the cord left to the grasp of the arms V" V A moment later the second series of teeth V comes into play against the teeth of the pinion V and the shaft V is revolved through such an are as to sweep the beak V over the whole inner length of the spring V and deposit the cord on hooks or other receiving devices, as may be convenient. The shaft V extends the Whole length of the machine from the hook to the jaws, and there are two arms besides those shown in Fig. 9 fixed to said shaft, that next the heck of the holder being similar to that just described. The consequence is, that as the cord is raised the tip of the arm (1 of the hook, Fig. 2, catches against the trip 10 and the spring (1 is extended, thus lowering the point of the hook and allowing the cord to be scraped against the scraper and abandoning said cord to the grasp of the arms at this end ofsaid cord.

The opening of the jaws above alluded to, and which is necessary for the removalefthe cord, is accomplished as follows: The arms or jaws having grasped the cord and the pinion being between the periods of its engagement with the series of teeth on the removing-wheel, the cam C comes into such a position as to allow S to enter the notch C, Fig. 3. This allows the action of the spiral spring S or its equivalent in thrusting the beveled brake against the surface of the circular cam by means of the bifurcated lever S By the friction of these two surfaces the beveled brake is thrown over inthe direction of the arrow, Fig. 7, and the beak S is projected against the periphery of the friction-wheel A 011 the rear shaft. The circular cam .is thus held practically rigid by the friction of B ,.and the inertia of the revolving head and the spindles carries them on, throwing the spindles out of the position occupied upon the upper surfaces of the sliding cams on the circular cam and allowing the spiral springs to come into play and throw open the jaws, liberating the cord. 7

I do not wish to be understood as limiting myself to the means herein specified for operating removing-arms swinging in front of the twisters in a directionat right angles to their length, as I believe swinging arms of this character to be broadly new in the art.

Thus far we have seen the operation of the machine, and all that now remains is to explain the means of bringing it into operative position preparatory to the repetition of this operation.

Of course the inertia of the power-shaft will carry it some little distance against the friction of the bevel B and the probabilities are, that said shaft will stop its motion in some position incompatible with the coincidence of the jaws with the horizontal plane. In order then to bring them back into this plane, the cam F Fig. 5, comes around after the stoppage of the power-shaft and brings the drop notch under the end of the lever T. This allows the intermediate gear to fall into gear with the crown-wheels A and 13 as heretofore explained. Now, as the wheel A is contion of the belt on the rear shaft, the wheel B is slowly revolved, and with it the powershaft and the notched gear B next it. At this time the lever M Fig. 16, has reached the depressed portion of the cam, and the tip of the lever M is in contact with the surface of the notched gear in readiness to enter the notch, as shown in the figure. As the notched gear is slowly revolved with the gear 13, the notch 13 is brought under the tip of the lever M, and said tip is allowed to enter it. At the same moment that part of the gear 13 which is cut away arrives under the intermediate gear and no further motion of the powershaft takes place, the intermediate gear being shortly removed by the action of the cam F. This position of the notched gear corresponds to the proper position of the jaws in the revolving head. (Shown in Fig. 1.) Now by the action of the lever and notched gear on the rtsshaft the opening lines of these jaws had already been so adjusted that when the jaws were in the same horizontal plane these lines were properlyadj usted forthe admission of the funnel, as explained, and hence all is now in readiness for the repetition of the operation described. \Vith the renewed action of the inward-turned projection on the camF there is a corresponding action of the track 1 by means of the arm L Fig. 5, which slides the brake 11 backward and liberates the carriage of the holding mechanism preparatory to the bringing of the said carriage back toward the working part of the machine, as described.

I do not wish to be understood as limiting myself to the exact detail of the constructions shown, as many minor departures from said details may be made without departing from the spirit of my invention.

I have thus described one form of my invention; but in some respects I construct my machine often differently from what has been above described. The rear shaft, for instance,

need not be made in two entirely separatesectious, and, indeed, I most frequently construct the same entire from end to end, as shown in Fig. 17, the constantly-revolving portion forming a sleeve or hollow shaft surrounding the intermittent shaft A, said sleeve bearing the constant pulley P and the gear A and worm A beyond the same, as shown. During the use of the pulley-belt upon the tight pulley on the power-shaft the motion of the same is transmitted through the gear A to the inner rear shaft A, and said shaft revolves backward against the motion of the sleeve on which is mounted the constantlyrevolving gear and worm. Again, instead of employing one of the tracks, as described, to slide back and forth for the liberation of the carriage, I more frequently use a third rod 18, running parallel to and back of the tracks, and provided with a collar 19 at the forward end of the same, or near the twisting mechanism, and another collar 20 at the other end of the rod. (See Fig. 2.) The extreme rear stantly revolving, owing to the constant acend of this rod is attached to the lever L Fig. 5. By impact of the carriage at the end of its journey at either end the clutch G is thrown out of gear with the bevel-wheels that run the driving-wheels, and thus the motion of the carriage is stopped at the end of its course at either end. In case of the use of this rod I employ a stop-lever for the carriage, having a depending peg 21. near its end, adapted to fall over the pin g on the carriage. This peg is rigidly attached to this brake, and as the brakelever is pivoted as described, when the lever L at the end of the machine acts upon the rod 18 and the collar 20 is thrust backward, there is a pin thereon which projects underneath the brake-lever near its rear end, as shown, Fig. 2. Now, near this rear end of the brake, said brake takes a downward turn, as shown, and as the pin on the collar 20 is thrust backward it acts upon this curve and tends to throw the brake up. This liberates the carriage from the peg 21 at the right momentthat is to say, just when the clutch is thrown into gear with the bevel-which brings the carriage back toward the twisting end of the machine. By this means there is a more positive resistance opposed to the tractile influence of the cord in its twisting and the carriage is sure not to be liberated until the machine is ready.

Another variation from the mechanism described, and one which is preferable, although the machine as described will also perform its proper functions, is the securing of the disk A at a later moment than that specified above.

moment that the cam O is operatin to secure the disk 15? a secondary notch in the cam C (shown in dotted lines in Fig. 3) comes into operation, and, being shallow, just allows a small portion of the belt on the rear pulleys to come onto the intermittent pulley, in order to bring the notch in the disk A opposite the point intended to secure it and keep the planes of the holding=jaws horizontal. This occurs, as above specified, j ustwhen these jaws are being brought into the same horizontal plane, and the double adjustment brings these jaws into a proper position for the reception of the cord.
