FEEDER FOR CARDlNG-ENGINES.

SPECIFICATION forming part of Letters Patent No. 469,206, dated February 16, 1892. Application filed June 12, 1891. Serial No. 395,984- (No model.)

To all whom it may concern,.-

Be it known that I, JACOB FRANK GEB, of Franklin, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Feeders for Carding-Engines, of which the following is a specitication.

The invention has relation to feeding mechanism for carding-engines, and is particularly 1o well adapted for use in connection with what is commonly known to those skilled in the art as Bramwell feeders.

It is the object of the invention to provide such improvements in mechanisms of the kind mentioned as will secure a positive operation and a quick stopping and starting of the toothed apron which supplies the Weighing-v scale. v

It is also the object of the invention to prozo vide improved means for actuating the patter or paddle employed to even the surface of the wool on the feed-apron.

Reference is to be had to the annexed drawings, and to the letters of reference marked thereon, forming a part of this specication,

the same letters designating the same parts or features, as the case maybe, Wherever they occur.

Of the said drawings, Figure 1 is a side ele- 3o vation of a Bramwell feeder equipped with the improvements. Fig. 2 is a side view, on

an enlarged scale, of the gear on the end of the shaft or roll which operates the toothed apron, the said gear constituting also a part 3 5 of the clutch hereinafterfullydescribed. Fig.

3 is a front elevation of the gear and shaft shown in Fig. 2 and illustrating also the entire clutch mechanism, the driving-gear being unclutched from the shaft. Fig. l is a view 4o similar to Fig..8, but showing the drivinggear clutched with the shaft. Fig. 5 is avertical sectional view of Fig. 4. Fig. 6 is a side or end view opposite that shown in Fig. 2.

Fig. 7 is a diagram showing the position of the clutch-operating lever when the drivinggear is in clutch with the apron-operating shaft.

As is well known to wool-carders having any knowledge of Bramwell feeders, the dis- 5o charge of the scale takes place at regular inbeen driven by means of a belt and pulleys tervals of time, whether the scale has or has not received its complement of wool, the operation of filling the scale and that of discharging the same being independent each of the other. It is very important, therefore, that the toothed apron should be so operated as to with certainty supply the scale 'within the allotted time. l

Heretofore the apron-operating shaft has 6o from the driving-shaft, and Aby reason of the liability of the belt slipping upon its pulleys the movement of the toothed apron has been at times irregular and uncertain. Again, the construction and arrangement of parts have been such that the apron might not be quickly stopped the moment the scale became filled, nor instantly started after the discharge of the scale, for the reason that there has been but a single point on the pulley or other means on the apron-operating shaft to actuate the stopping and starting means, so that if such point had barely passed the locking-lever or trip-latch the said apron would continue to move or stand still, as the case might be, until the said tripping-point again came around.

By the invention herein described the objection mentioned is overcome, and as the improvements have nothing to do with other parts of the ymachine. than those Cextending between the driving-shaft and apron-operating shaft and the means for actuating the patter co-operating parts of the feeder have not been fully illustrated and need not be described in detail.

In the drawings, a designates the frame of the feeder. y

h is the driving-shaft, and c the shaft over which the toothed apron (not shown) travels and by which it is moved.

d is a vertically-arranged shaft, provided on its lower end with a bevel-gear e, meshing with a similar gear f on the driving-shaft, and having upon its upper end a bevel-gear g, meshing with and adapted to drive a larger 95 bevel-gear 7L on the apron-operating shaft c.

The gear h is constructed and arranged to turn loosely on the shaft c, but is frictionally connected with the collar h2, as hereinafter explained, and -is provided with an innerroo toothed edge or flange t', so as to adapt it to also forni the part of a clutch Fitted to co-operate with a toothed clutch partj adjacent to the inner face of the Wheel h.

The clutch partyl consists of a flanged ring surrounding the shaft e and provided with inwardlyprojecting pins 7c, which extend through the web of a disk Z, fast on the shaft c.

m designates pins, which extend radially from the pins 7c through inclined slots n in the iiange 0 of a wheel p, adapted to turn loosely on the shaft c.

Q designates a helical spring, one end of which is secured to the web of the disk l and the other to the flange or rim o of the wheel p, the said spring operating to turn the wheel la with respect to the wheel]- in the direction indicated by the arrow in Fig. 3, and as a consequence move the clutch party' through the mediunrot' the pins 7e m and inclined slot n into contact with the clutch device of wheel 7L.

fr designates lugs or projections extending` radially from the periphery of the flange o of wheel p.

s designates the weighingscale on one end of a eounterweighted lever t, with which eounterweighted arm of the said lever there is connected, by means of a rodor wire u, the outer end of the horizontal arm o of an angular lever w, the vertical arm a; of which is provided on its end with a laterally-projecting pin or stud y, adapted to fall into a notch e', formed in the forward end of a weighted lever d', which latter device, when not latched I or held down bythe pin y ofarm w, is adapted to be moved by means of its counterweight h', so as that its inner end will be brought into the path of movement of the projections o of the flange of wheel p.

c is a tripping-lever (common in the construction of Bramwell feeders) provided with a laterally-projecting pin CZ', adapted when the scale s isA discharged to be drawn down upon and depress the lever ct', so as that the pin y, resting against the inclined surface e on the end of lever e', (see Fig. 2,) may drop into the notch ,e and latch or hold the said lever ct down out of tlie way of the lugs or projections r on the periphery 0 of the wheel p. (See Fig. 7.) The means for actuating the lever c', as above noted,l may be the same as what is shown and described for operating a lever having a similar function in the patent to Bramwell, No. 216,373, dated `lune 10, 1879, and forms no part of this invention.

f designates an eccentric on the shaft d,

which eccentric is surrounded by the strap g',

connected with one end ot` the pitman 7L', the opposite end of which is adj ustablyeonnected with theA upright arm of the shank t" of patterj. (See dotted lines, Fig. l.) The shank of the patter is fulcrurned at 7s.

In the use of myimprovements, when the machine is in operation and the toothed apron is running to take the wool from the box and supply it to the scale, the clutch mechanism will be in the position represented in Figs. #i and 5, and the lever d will be held down out ot the path of movement of the lugs r, as shown in detail in Fig. 7. As soon as the complement of Wool is supplied to the scale the latter will be depressed, raising the weighted arm of lever t and throwing the locking-pin g) out of the notch z of lever d', allowing said notched end to be raised bythe weight b on the opposite end and bringing said notched end into the path of movement ofthe lugs o1. The instant the lever a engages the lugs r it will stop the rotation of the wheel p, and the clutch party' continuing to rotate or 4move for a short distance will, through the medium of pins 7e m, connected therewith, (the latter pins operating in slots 01,) be drawn away from the clutching means of wheel e', and the latter will move without effecting a movement of the toothed apron.V

lVhen the scale discharges its load, the tripping-lever c will, by the meansof its pin d', depress the lever a', as before described, drawing the said lever out of the path of lugs 0', permitting it to be held down by the pin y and allowing the spring q to instantly move the wheel p in the direction of the arrow, Fig. 4, clutching the partj with the part i and at once starting the movement of the toothed feeding-apron. As the shaft d rotates, and as it does so quite rapidly, the patter j will be operated quite rapidly and perfectly smooth the upper surface of the Wool upon the feeding-apron. rlhe gear 7L is frietionally connected with the collar or hub 71,2, keyed or otherwise secured to the shaft c by means ot a split clamping-ring h3, which embraces a strip of leather arranged in a groove in the said collar, and said split ring is so constructed and arranged as to exert a hugging or frictional influence upon the collar. One of the ends of the said split ring is connected to a stud 7L, which is in turn connected to the gear 7L. This provision is made in order to prevent any shock tothe machine when lever c is operated to engage a lug r to stop the machine, since it will allow gear 7L to turn independently of the shaft and without operating the same before the said gear is diseonnected from the wheel j.

It is to be noted that with my improvements the apron-operating shaft is actuated with positiveness and certainty, and that the toothed apron is stopped the instant the scale receives its complement of material, and started the moment the scale discharges its contents.

It is obvious that changes may be made in the form and arrangement of parts comprising my improvements Without departing from the nature or spirit of the invention.

Having thus described my improvements and explained a way of constructing and using the same, though without attempting to set forth all ofthe forms in whiehit maybe made or all of its modes of use, I declare that what I claim is- IOO IIO
