Definitions
- a rockingshaft, D, near the upperypart of the machine, has its bearings at a, and has secured to it, near each end, a pair of arms, E
- the block F whiuch extends across the machine inside of the frame A, is secured rigidly to the clamps b on the ends of the arms E, and this block has attached to its face a card, d, the points of the teeth of which incline downward.
- a strip or plate of metal, c extending the whole length of the block, is Secured by screws l to the top' of it.
- a piece of metal, j' of the form shown in Section, Fig. 2,- also extends the length of the block F, and it is hinged near each end to the upper part of the clamp 1),'at 2, the clamp being bent over the top of the block F, as shown in Fig. 2.
- a shaft, II lying parallel to the shaft D, has its bearings in and projects through the arms E, between the shaft D and the ends of the arms.
- a screw, 14 To this shaft II is secured, at or near the middle of its length, by a screw, 14, the short arin I, to which is pivoted, at 5, another arm, K, the other end of which is pivoted at 6 to the top of the piece f of the nippers.
- a short arm, g is Secured to the outer end of the shaft II, beyond ,the arm E, and hangs down below it.
- This arm g is secured to the shaft II by a set-screw, 7, Fig. 1, and is continued down and bent back, as at 8, Fig. 2.
- Aspring, e draws the lower end of the arm g toward the'block F and opens the j aw 3 of tlie nippers. Jaw is held vopen during the descent of the block F,Aand is closed and held shut during its'ascent in the following manner:
- a bent lever, L having a friction-roll, h, at, each end of it, is pivoted at to a cross-brace at one end of the frame A of the machine.
- This lever is vibrated at proper intervals by a cam, M, (dotted in Fig. 2,) secured to the shaft B, which.
- the cam M is so formed that it shal.1 retain the lever L in the position shown in Fig. 2 for a certain period of time, while the bent portion 8 of the arm g is so arranged that it will bear against the friction-roll l at the upper end of the lever L during the ascent This of the block F and arms and thus keep the j aw 3 shut. until. the block F has reached the highest point toL which it ascends, at which time the roll h drops off the point 24 of the cam M, when the retraction of the spring e opens the jaw 3.
- a doffer, N is supported in suitable bearings inthe frame A, and is revolved in the direction of its arrow by the gear k on the end of its shaft engaging with a small intermediate gear on an arm, m, which gear in turn engages withv one on the end of the roll n, that strips or aidsin stripping the doffer.
- a pulley, O over which and over a pulley, 0, on the drive- Y shaft B, a belt or cord passes to give motion to the roll n.
- Another roll, p lies immediately over the roll n, and; these rollsl take the lapfrom ⁇ the doffer N and deliver ⁇ it toa pair of: calender-rolls, q,- hung on the arms P, which rise from the back of the frame A. Before enteringthese latter rolls, however, the lapl is passed-through a-hole in a piece of sheet metal,
- the sliver which rises from the cross-brace s, which' connects andsteadies the arm P;
- the sliver is thus, condensed in ⁇ the usual; manner topass into the can.
- the rolls ⁇ q are driven by a cord or belt over a small pulleyon theshaft of one lof them, which passes over the pulley o, beforereferred to. (The cords or belts-arenot shown inthe drawings.)
- the ratchet-wheel c is fed in the direction of -its arrow,one notch at each revolution of theshaft B, in the following manner:
- a cam, fw, on the shaft B vibrates a lever, y, pivotedv at 15 to the side of the frame A, and to this ⁇ lever y, near the middle of its length, is pivoted, at 16, a long rod, z, in the upper end-of which is inserted a pin, 17, that engages with..
- a i broad flat lever, T which is pivoted at 1J to a cross-brace of the frameA, and is forked at its; lower end-,forming acam, a', that embraces the shaft B, between the side of theframe and the cam M, previously spoken of.
- a pin, 10, Fig. 1 proj ects from the side of this latter cam into the cam. c', and vibrates the lever T 'at the. proper intervals. This causes the bar S t0l push, back the roll x from the bar R and .allowthe fibers to be drawn through between the roll and the bar.
- the system consisting ofthe bar S, lever T,- and its cam is in duplicate at the other end of the machine, so that as the lever Tfisvibrated in one direction the :two bars S willbear one against, each end of vthe roll a: and push it back square, (or withi out throwing it out of parallelism with the roll u.)
- the nextvibrationof the levers T in the opposite direction operates in the same manner'the roll x, belonging to theset of machinlery on the opposite side of the machine.
- V These vibrations are effected in the following manner: An eccentric, W, secured to the shaft B, near one side of the frame, is embraced by a strap which is attached at c to a pitman, X, the upper end of which is connected to one of the arms E in amanner which allows ofv an adjustment lof the vibration of the arms.
- a screw, e', on the end of the Thisl gives two means of adjusting the vibration of the arms Fl: first, by altering the length ofthe pitman, and, second, by altering the point at which it is attached to the arm E.
- the block F now begins to ascend, and at this instantv the levers T are vibrated, and thebars S, attached to them, are moved in the direction of their arrows. This pushes back the roll w away from the bar R sufficiently to allow the lap to be fed up, and at ⁇ the same time the nippers draw the fibers from the end of the lap and carry them up past the face of the card t, by which the other ends of these same fibers are combed out as theblockFascends.
- the spring 4C presses this roll up and nips the lap, feed is taking place, the lap, as it comes through the rolls, will be drawn up between the upper roll and the knife-edge, and then the fibers which are grasped by the nippers will be torn off from the lap, to be carried up past the card above the rolls.
- the block F again descends to repeat these operations, the cardt is cleaned by the card d, which passes in contact with it, and this latter card is in turn cleaned at its neXt ascent by the card b', whichis in its turn cleaned by the card d as it descends.
- the doffer for receiving said carded or combed tufts preparatory to their being formed into a continuoussliver substantially as described. 4.
- the rolls for stripping the doffer and taking' off the c otton in a continuous sliver substantially as described.
