SPECIFICATION forming part of Letters Patent No. 284,416, dated September 4, 1883.

To all whom it may concern.-

and useful Improvement in Warping and Beaming Machines, of which the following is a full, clear, and exact description, reference consists of certain improvements pertaining to different parts of the machine, as hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation, and Fig. 2 is a plan view, of a warping and beaming machine embodying our improvements. Fig. 1 is an elevation, andFig. 2 is a plan view, of the starting-on motion.

Fig. 3 is an elevation of the measuring apparatus and a part of the stopmotion, and-Fig.

,3 is a detail view of the stop-motion.

pinions, a a either of which is adapted to engage with a bevel-pinion, b, on one end of the shaft 11. On the opposite end of the 0 shaft b is a friction-roller, c, which is adapted to drive the section-shaft d by means of the friction-plate d, forming one of the flanges against which the section of warp is wound.

The roller 0 is loosely mounted on the shaft 5 respond to the speed of the section-shaft d,

the screw 0 is provided with a ratchet-wheel, a, which is rotated to turn the screw and adjust the said roller by means of a pawl on one end of the elbow-lever a", (see Fig. 7 and an eccentiic, d", on the section-shaft d, in con tact with which eccentric the free end; of the l'everc is placed. At each revolution of the cam the lever is rocked and. the pawlmoves the ratchet. Be it known that we, SAMUEL STANDRING HALL and J OSEPH WALMsLEY, of Bury, near 3 Manchester, England, have invented a new I The action of the pawl is adapted to be regulated by a slot in the eccentric (1 whereby the latter can be adjusted nearer to or farther from the center of the shaft d to vary the sweep of the lever.

In practice the roller 0 is to be so adjusted that it will be moved along the radius of the plate cl, from near the center to the circumference thereof, during each operation of wind ing a section of warp on the shaft d. The object of so adjusting the friction-roller is to vary the speed of the section-reel, so that the warp shall be wound thereon at a uniform rate of speed from beginning to end. As the section increases in diameter by the successive courses of warp wound in its formation, the warp, if the movement of section -reel were uniform, would necessarily be wound at an increasing rate of speed, which would tend to disturb the uniformity of tension on the warp,

; and thus cause the sections, when completed, Figs. 4, 5, 6, and 7 are detailviews of'other parts of the machine, and Fig. 8 shows a modified Q; form of gearing. On the drum-shaft a are mounted two bevelto be unequal in size and in length of warp. It of is great importance, however, when the sections come to be wound on the loom-beam,

that such inequalities should not exist, and

therefore we give a uniformly decreasing rate of speed to. the section-reel as the diame ter of the section increases by causing the driving friction-roller to be moved gradually nearer the circumference of the friction-plate d, which has the effect of throwing the said friction-gears into constantly-increasing disproportion as regards the diameters of their acting frictional surface, and thus causing a corresponding disproportion of speed. For

instance, if we begin the winding of asectionshaft moving at the rate of one hundred revolutions a minute, we may gradually diminish this rate of speed so that the shaft shall move at the rate of only sixty revolutions a minute at the completion of the section, and thus the warp may be drawn off from the beamingframe under a uniform tension, notwithstanding the increasing diameter of the section into which it is wound.

For certain patterns it is important that the warp of some of the sections shall be wound in a reverse direction from that of others. To adapt the machine to be reversed at will for this purpose the pinions a c on the drumshaft a are connected together by means of a rack-bar, fi, andcclutch-forks f taking into grooves in the bosses of the pinions, and a too pinion, f,- secured to a shaft, f,- is placed in engagement with the rack-bar, and is adapted to be rotated by a handle, f, on the shaft f to shift the rack-bar and cause the pinions a a to move along the shaft a. Either of the pinions a a may thus be thrown into engagement with the pinion b on the shaft carrying the driving friction-roller, and the motion of said roller may be reversed accordingly to change the direction of the winding of the warp on the section-shaft.

' To determine whether a given number of 1 yards of warp is being wound into each section,

5 v will thus produce a corresponding number of gear-wheels, F F, and the shaft of the change- I wheel is provided with a worm, F gearing with a pinion, F on the shaft of the dial. 1 A

given number of revolutions of the rollerA revolutions of the dial-plate, and the number of halfyards of warp passed over the roller will be recorded on a graduated scale on the dial by a stationary pointer, F, as shown in Fig. 2. On the shaft of the change-wheel F is secureda cam, E, (see Figs. 3, 3%) and a spring-hammer, D, having a projection thereon bearing against the cam, is adapted to be forced back by the revolution of the cam until the projection on the hammer slips off the eccentric lip of the cam and causes the hammer to strike the bell C. An audible signal is 7 thus given at each revolution of the cam, which represents 'a given number of revolutions of the measuring-roller, and consequently a given number of yards of warp which should have passed over said roller to the section-shaft if the tension on the warp is properly adjusted.

To determine Whether said given number of yardshave actually been wound into the section, the section-shaft is provided with a worm, p, with which engages a wheel, p, adapted to record the revolutions of said shaft. The wheel 19 is to be provided with holes, into which a number of pegs may be inserted by the operator to tally the revolutions of said wheel. A given number of revolutions of this wheel will represent a given number of revolutions of the section-shaft. A given number of revolutions of the section-shaft represent a given number of yards wound into the section, supposing the tension to be properly adjusted, and if the operator observes that the given number of yards announced by the bell-signal of the measuring-roller have been recorded by the wheel 12, he will understand that'the tension on the warp is properly adjusted, and

that the size of the section properly corresponds with the number of yards wound therein. Any discrepancy between the record of the bell and that of the wheel 19' will indicate that the tension on the warp is either too slack or too taut, and that the section is not increasing in size in such proportion that a required number of yards shall be contained in a completed section of a required size. the tension on the warp is to be adjusted to produce the desired efiect.

In order to be able to stop the machine instantly when a desired number of yards of warp have been wound into a section, and to startit again at a high rateof speed without loss of time, we provide a starting-on motion and a stop-motion, which we will now proceed to describe.

Referring to Figs. 1 and'2, H indicates a band pulley or drum, which is loosely mounted on the shaft a, and I is a friction-plate rigidly secured to the end of said shaft, which plate is adapted to receive motion from the pulley when the latter is held in contact therewith. As a means of adjusting the pulley into contact with the plate, a clutch-collar, A, is loosely mounted on the shaft a on the opposite side of the pulley fromthe plate, and to this collar is rigidly attached a lever, B, to one end of which In such case is pivoted a vertical rod, 0, having a lip, D, Y

adapted to engage with a supporting-bracket, E, and to be held yieldingly in engagement therewith by a spring, F. For moving the rod 0 upward into such engagement with the bracket E, a jointed foot-lever, G, is adapted to depress the end of lever B. opposite from that to which the rod Ois connected, as shown in dotted lines, so as to throw said lever from a horizontal to an inclined position. \Vhen thus depressed, the lever causes the clutchcollar A to turn upon the shaft a with its bevel moving against the corresponding bevel of a stationary clutch-collar, 'A", which gives a longitudinal movement to the collar A, causing it to slide against the pulley Hand to force the latter into contact with the plate I. In this manner motion may be instantly communicated to the plate I, and through it to the shaft on, which runs the machine, and the motion will continue to be communicated so longasthe rod 0 is allowed to remain in engagement with the bracket E. The upper end of the rod 0 is provided with a cord, k, passing around pulleys O and connected at its other end to the weighted rod i, which is adapted, under conditions yet to be explained, to fall and draw the rod G to one side, so that the lip D on the said rod may slip off the bracket E and allow the rod to drop through the bracket, and the lever B thereby to regain its normal position. To force the rod 0 and the lever B to move as described, the lever B is connected to an oscillatory frame, J, which is provided with a weight, K, adapted to overbalance the lever B when the latter is not locked by the engagement of the rod 0 with the bracket E. When the lever B is thus lifted to the position'shown in full lines, the collar A is rotated in such manner that the bevel of its clutch is moved from the corre sponding bevel of the stationary clutch, and

the pressure on the drum is thus released, allowing the latterto move out of contactfwith the friction-plate, whereupon the machine may be stopped.

The weighted rod, which is adapted to operate the rod 0 by means of the cord k, is adapted to be supported in a bracket, P, by means of a projectiomi. Inserted in a circular plate, j which is mountedon'the changewheel stud j, is an eccentrically located pin, j, which is adapted at each revolution of the said plate and change-wheel to strikethe rodi and cause the projection 73 to slip from the supporting-bracket i and. allow the rod to drop. In the circular plate j? is a slot, j, (see Fig. 3,) and in theslot is ascrew, j fixed in the boss of thebell-cam, bywhich means theplateand pin are to be adjusted to allow the rod to be raised into position for acting again. A weightyi is attached to the lower end of the rod 43 to se cure the proper operation of the rod 0 when therod i is caused to fall. In this manner, at each revolution of the change -wheel, which represents a given number of yards wound into the section, the machine is made to stop automatically, and thus each section may be made to contain exactly a desired number of yards of warp. We weight the section by means of the compoundlevers m and n, to the latter of which is secured an iron strap, n, lined with leather, which passes over a ratchet-roller on 'Ver n. The lever m, which is weighted, and the arm carrying the roller 8 are rigidly attached i to the same shaft, r, with the ratchet, and are so arranged with respect to each other that the said weighted lever in will cause the roller to bear up against the section, aud t-he roller will be kept from vibrating by the binding ,eflect of the leather lining of the strap n upon the ratchet-roller. The weighted lever n, with its strap n, thus serves as a brake for binding the ratchet and holding it against the action of the weight of lever m so that the rotation of the section in contact with the pressure-roller s cannot cause the roller to vibrate, but will move it down gradually a ainst the effect of the weight on lever m as the diameter of the sectionincrease's. By this mechanism, of which a plan view is given in Fig. 4, the pressureroller is made to bear equally upon the different layers or courses of the section, to the end that all the sections, when completed, shall be of an equal diameter.

The wraith 0, which is shown enlarged in Fig. 5, is made in two parts, 0 0 hinged together end to end, and provided with suitable connections, 0 with a right and left hand screw cut on the spindle 0, whereby the two parts may be expanded or contracted by rotating the spindle.

I11 Fig. 8 we show a modified form of gea ing for driving the section-flange. The flange is provided on one side with concentric toothed or pegged rings 01*, one arranged within another, and the frictional driving-shaft b is provided with a pinion, d adapted to gear with any one of the ringsdi When this gearing is used instead of the frictional gears c d, the machine must be stopped to move the pinion from one ring of the flange to the next.
