My invention has for its object improvements in warping or reeling machines adapted to reel any fibrous material for constituting the warp in the weaving of a fabric.

A primary object of my invention is to associate with the usual warping reel or drum carried on a wheeled frame with a separate headpiece carrying all the controlling members adapted to ensure the rotation and translationalshifting of the reeling drum. This arrangement of separate controlling means on the head-piece allows an easy removal and change of the reeling drum as soon as it is loaded so that there is not time lost in such a change of reel while at the same time the cost of the substitute reels reduced to the actual reeling means is much lower than heretofore.

According to a further object of the invention, the head-piece is also provided with various controlling members in addition. to those referred to, said controlling members cooperating with the meters giving out the number of revolutions of the drum and with further meters for measuring the shifting movements of said drum and also with the braking and clutching members.

The invention provides also for a motor carried by the head-piece and controlling through a clutch the Oldham or the like coupling means driving the drum around its axis.

According to a still further object of my invention, the reel or drum braking means are constituted by a braking band directly engaging the drum and controlled through the head-piece.

My invention also provides for a duplicate system of meters giving out the location of the reel or drum along its axis, one of the elementary meters providing a rough measurement and the other a highly accurate measurement.

Furthermore, the thread guiding reeds are fed through the agenc of a carriage that is automatically shifted transversally with reference to the drum axis in proportion with the increase in diameter of the thread coiled over said drum.

According to a further feature of the invention, the revolution meter automatically stops operation after a predetermined number of revolutions Which removes the objectionable efiect of any omission in the operation of hand-actuated clutches as provided heretofore in reeling machines.

Further advantages and features of m invention will appear in the reading of the following description of a preferred embodiment orf'said invention that should be considered only as an example withou any bind ng sense Intha-a companying drawings illustrating said embodimen Fig. 1 illustrates the complete warp frame in elevational view as seen from the bobbin board.

Fig. 13 is a plan view showing the location of the creel with reference to the actual reeling means fed thereby.

Turning more particularly to Figs. 1, 2 and 13, it is apparent that the machine comprises a reeling drum 2 permanently secured to a carriage .3 mounted on four swivelling wheels allowing both an easy displacement over any flat area and an accurate guiding over the rails 5. Said drum 2 is removably associated with a head-piece I also mounted on the rails 5 and carrying the various controlling means ensuring the rotation and the longitudinal shifting of the drum as well as the controlling means for the brake acting on the drum and for" the clutch operativelyconnecting' said drum with the head-piece. {said head.

piece also carries as disclosed hereinafter various checking apparatuses, and meter 'Ifhe .reed -carrier 6 shown more particularly in cross section in Fig. is anchored to the ground along the axis of the bobbin board III (Fig. 13) and includes a movable carriage adapted to move perpendicularly to the axis of the drum under the action of a rack and pinion system 46-41 through the progression of the drum carriage 3 as the latter moves longitudinally over the rails 5 as will be disclosed also hereinafter.

The drum 2 that actually carries no control means is entirely closed and is made of metal sheet and appears as a large so-called bottle spool. Its capacity is considerable. It is provided with an adjustable brake system described provide for a secure connection between the headpiece and the drum I.

The head-piece may move over the rails 5 anchored in the ground perpendicularly to the axis of the creel through a sort of towing action executed on a rack I4 also anchored in the ground. Said head piece includes a driving motor 8, a friction clutch I5 (Fig. 3) actuated by an 'electromagnet, a pinion 9 for shifting the head piece over the rails 5 and the speed of which with reference to the speed of rotation of the drum may be increased when desired to ahigh rate, a meter I 0 measuring the number of revolutions of the drum and adapted to control electrically the stopping of the machine, two dials adapted to measure the shifting of the drum with reference to the creel and electromagnets not illustrated actuating the band brake of the drum,

2. control lever I2 for rapid right hand and left hand displacements and lastly the electric apparatuses required for controlling from a distance and stopping of the different mechanisms forming the machine.

The motor 8 controls through the belts I00 an intermediary shaft I6 on the head piece, which shaft I6 rotates permanently. Said shaft (Fig. 3) carries for rotation therewith a sprocket wheel I'I driving the rapid drive gear as described hereinafter and it also carries a pinion I8 mounted loosely on said shaft I6. Said pinion is held between two flanges I9 and I9 forming the above mentioned clutch, that are longitudinally keyed to the shaft I6 and of which one is axially movable and is constantly urged against the pinion I8 by an adjustable compression Spring 20. Said flange is submitted through the agency of the lever 2| to the action of an electromagnet HQ,

and of a return spring 22 (Fig. 6) whereby when the electromagnet is energized the compression spring is released while a sliding connection is provided between the driving shaft I6 and the pinion I8 through the flange IS considered. The pinion I8 drives a toothed wheel 23 on the main control shaft 24 of the head piece. Said shaft includes on the outside ofthe head piece an Oldham coupling I3 through which said shaft drives the drum 2.

The shifting of the drum carriage and head piece over the rails 5 is obtained through the sprocket pinion 25 keyed to the shaft 24 and that drives through a chain or the like positive mechanism a gear system 28,'a swing frame carrying gears 293fl3I-32 controlling a worm that "through the agency of a worm wheel 34 drives the pinion 9 that is keyed to the same auxiliary shaft as said worm wheel 34. Said pinion 9 engages without any clearance the rack I4 that is anchored to the ground through it two ends.

To each revolution of the drum corresponds a displacement or shifting of the head piece and of the drum, the importance of which depends on the gears 29-30-3I-32 that have been chosen.

The displacement of the head piece is measured by a meter I I with two dials of conventional type as shown in Figs. 1, 2 and 8, said meter being controlled through the worm shaft 35 through the agency of a pair of bevel gears 36 and a connecting shaft I0 (Fig. 12). Said shaft drives the handsover the meter dials. The left hand dial (Fig. 8) carries a scale ranging from zero to 1,000 millimeters and that on the right hand between zero and 100 millimeters. The smaller hand IOI of each dial gives out the accurate positioning of the head piece and carriage system with reference to a stationary point, i. e. in the case considered the reed carrier. These two hands IGI allow obtaining very accurately the position of the line joining the cylindrical and conical parts of the drum with reference to the tooth of the reed engaged by the first threads of the section. The larger hand I02 of each dial gives out the amount by which the carriage and head piece system is shifted with reference to the reed for each section. Through construction the small hands IOI are not adjustable while the larger hands are adapted to be returned to zero at the beginning of the operation of each'section so as to indicate the exact displacement of the system. To this end,

:' they are driven through a small driving clutch allowing said return to zero as soon as a suitable mill knob is actuated. During operation, the larger hand I02 of the right hand dial moves ten times more quickly than the hand I82 on the left hand dial, which allows an accurate reading of the displacement of the system that may be estimated with an error less than 0.25 millimeter, the right hand dial giving out large scale indications while the left hand dial provides the rougher indications Each dial is provided with an adjustable mark 37 the position of which on the dial scale may be modified as required. These two marks are adjusted in accordance with the exact breadth of the thread section on the drum. The hands or pointers may thus be brought to register with the scale graduations corresponding to the breadth of the thread sections to be reeled starting from said marks.

The main control shaft of the head piece carries a pinion controlling positively a transversal shaft that through the agency of a worm and worm wheel gear controls the meter l0 recording the number of revolutions executed by the drum. This meter I 0 (Figs. 9 and 10) of the cylinder type is constituted by a cylindrical body carrying a scale and provided with a helical groove I03.

Removable keys 40 of which one is shown in position in Figure 9 on the cylinder act on a releasing slide 33 that produces a stopping of the warp frame after a predetermined number of revolutions. To produce such a stopping, the slider 38 that is actuated by the keys controls simultaneously two electric switches. One of the switches S illustrated diagrammatically in Fig. 9, switches off the current passing through the circuit C feeding the coils controlling the clutchand braking contact-pieces and produces thus the immediate stopping of the warp drum. The second switch closes the electric circuit passing through a signalling lamp lying in front of the operator inside the box or panelcarrying the control knobs for the machine.

The meter I0 includes as special features a double automatic clutch I04 associated with a return to zero handwheel M for driving the cylinder I0 forwardly or rearwardly without the operator interfering and further the rocking Slider 38 mentioned hereinabove that allows a rapid return to zero.

The automatic clutch I04 operating through rollers and cam slopes is not novel per se but heretofore the clutch operating for forward progression did not allow a perfect connection between the cylinder of the meter with its drive. As a matter of fact, in prior art, the cylinder was liable to slide in the direction of progression quicker than its driving member under the action of any vibration of the system. Such untimely displacements are generally inconsiderable, of the order of a few angular minutes but they are generally frequent and produce through their repetition an important shifting that may correspond to a final error equal to one revolution of the drum. The second series of rollers and cam slopes incorporated to the clutch I04 removes such a drawback and provides for an accurate positioning of the cylinder in both directions of rotation with reference to its driving member.

The rocking slider 38 slides freely over a fluted shaft 39 and rotates in unison therewith by reason of the presence of a connecting key. Said shaft carries a projection forming a current breaking switch between the terminals of the circuit. A return spring urges said projection in a direction such that the projection restores electrical connection between the terminals and at the same time the slider is urged by the shaft into the helical groove I03 of the meter cylinder I0.

During operation, the rotary cylinder drives the slider 38 along a line parallel to its axis and the openings I05 in the cylinder groove pass in succession underneath a boss provided on the slider 38. When a key 40 (Fig. 9) fitted in one of said openings I05 appears in the path of the slider. the latter rocks to a certain extent together with the shaft 39 and the projection thereon so that the circuit is broken and the machine stops.

In order to avoid the necessity of returning the slider into its starting position by operating the handwheel 4| in the opposite direction which is long and tedious, the rocking slider 38 may be shifted axially of its guiding shaft after a raising movement thereof. Thusat the end of the metering operation, the slider may be rockedout of the groove by hand so that its tail'end may move out of its helical groove I03 after which it is slid axially as stated alone its shaft to register with the starting portion of the groove I03 into which it is caused to enter through a reverse rocking movement. It is then sufficient to make the cylinder rotat through a fraction of a revolution in order that a stop provided on the cylinder may abut against the slider exactly in the zero or starting position thereof.

The head piece also carries a quick operating device for shifting. the warp frame over the rails 5 which is provided as follows (Figs. '6 and '7) The auxiliary shaft I6 controlled by the motor carries a sprocket pinion I'I already mentioned that through the agency of a chain controls a speed reversing gear constituted by two pinions 4343 rotating in opposite directions in apermanent manner (Fig. 6).

Coaxially with said pinions, a shaft 60 carry- 6 ing a'double cone 42 keyed thereto controls in either direction and at a high speed the above mentioned worm through the agency of the gear wheels 44. The worm 35 transmits, as already disclosed, its movement to the worm wheel 34 and to the pinion 9 producing thus the rapid displacement of the head piece over its rails. To produce a connection in either direction, the shaft 60 carrying the cone 42 is adapted to move longitudinally of its axis. This displacement of the shaft 60 is controlled through an outer lever I2 (Figs. 1 and 2) that controls the angular position of a shaft 53 carrying at its end a pinion 6!. The latter meshes with a rack cut in a collar 62 servihgas a bearing for the shaft'60 and adapted to move axially in unison therewith. Thus, the

displacement of the rack under the action of the lever I2 produces a clutching which provides a rapid movement of the head piece in either direction.

The head piece thus described is coupled with the drum carriage 3 through two key coupling means. Therefore when a warp drum'is finished the operator may easily and rapidly return the head piece into its original position in which it is ready to receive the next empty drum in place of the finished drum.

Each drum carriage is constituted by a frame 3 of shaped iron entirely welded and to which are secured four wheels 4 adapted to assume any angular setting and that may roll either on the same rails as the head piece or on the ground. Said carcase carries the drum 2 constituted by a welded system of iron sheets and including at its end a cone I2 of predetermined angle made also of sheet metal. On the side of the drum furthest removed from the cone is mounted a brake "I3 adapted to operate both during winding and unwinding (Fig. 11). V

In said brake, thepoint 56 is that at which the brake band 51 is secured to the drum carriage 3 and the movable securing end 58 is carried by a square-shaped lever 59 tensioning the band 51 under the action of the spring 59 acting on said lever 59. Said bell crank lever is controlled by an electromagnet M on the headpiece and releases the drum or brakes it during the warping operation.

7 This bell crank lever allows the following standard advantages:

(1. Increasing the action of the brake when the drum rotates as shown by the arrow 0 during the warping so as to provide a speedy and energetic braking.

1). Reducing the action of the brake when the drum rotates in the direction'of the arrow E during the sizing or dressing during which operation it is carried along by the unwinding sheet of threads. In the first case, there is a self fastening operation and in the second case a self unfastening operation.

The machine includes lastly a reed carrier I; (Fig. 5) that is independent and anchored to the ground.

Each drum carriage is provided along and to the front'of .the frame on the Side facing the creel III (Fig. 13) with a rack 46 meshing with the pinion 41 (Fig. 5) projecting beyond'the stationary reed carrier 6. Inside said carrier, said pinion drives a shaft 48 that through the-agency of a free wheel and of a clutch drives in its turn a pinion meshing with a rack 50 rigid with the carriage to which are secured the reeds 5I-5I and the thread guiding roller 5%.. A

counterweight 53 suspended from the chain 54 the other end of which is secured to said carriage 1 urges the latter forwardly towards the side corresponding to the warp drum. An operating lever 55 releases the reed carrier I with reference to its control shaft. At the beginning of the warping of a section H (Fig. 13), the reed carrier. 1 is located completely to the front with the thread guiding roller 52 very near the drum. During the warping, the drum carriage moves under the control of the head piece and its rack 46 controls consequently the rotation of the pinion 47 and shaft 48 and thereby displaces the rack 30 so as to make the carrier 1 recede in proportion with the accumulation of threads on the drum 2. In other words, considering a triangle the hypotenuse of which is the generating line of the conical end of the warp drum, the longer side the extent of they lateral shifting of the carriage 3 and the small side the extent of movement of the reed carrying carriage I, it will be noticed that the ratio between the shiftings of the two

carriages

3 and 1 is such that the thread guiding roll 52 may follow exactly the accumulation of threads over the sloping cone of the warping drum. This provides an accurate guiding of the sheet of threads whereby it is possible to position the threads in a very uniform manner throughout each section.
