BURRlNG-MACHINE.
SPECIFILIAQLON forming part of Letters Patent No. 439,194, dated October 28, 1890. Application filed July 30, 1887. Serial No- Z45,'762. (No model.)
To all whom it may concern:
Be it known that I, FREDERICK G. SARGENT, of Graniteville, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Burring- Machines, of which the following is a specification.
My invention relates to machines for picking and burring wool; and it consists in certain new and useful constructions and combinations of the several parts thereof, substantially as hereinafter described and claimed.
In the drawings, Figure 1 is a side elevation of a burring-machine containing my improvements. Fig. 2 is a longitudinal vertical central section of the same. Fig. 3 is a side elevation of a machine for burring, containing a modification of my invention. Fig. 4 is a longitudinal vertical central section of the same. Fig. 5 is a portion of a longitudinal section of the 'burring-cylinder, showing the arrangement of the teeth in the same.
Fig. 6 is an enlarged view of two of the teeth shown in Fig. 5, showing the dividing wire or plate between them, which sustains the wool while being burred.
A is the frame and easing of the machine. F is the feed-apron, passing around rollers ff, upon which the wool is spread.
F F are the feed-rolls, which take the wool from the apron and feed it forward to the picker-cylinder P. The latter revolves in the direction indicated by the arrow and carries the fiberover the grid G beneath it, through which the coarser impurities and dirt drop into the space beneath.
B is the hurling-cylinder, which is provided with teeth and revolves in the direction indicated by the arrow, taking the fiber from the picker-cylinder, where they pass each other. When the wool-fiber is thus deposited upon the hurling-cylinder, most of its fiber is held within and between the teeth of the latter and the burrs float or lie on its outer surface, and when they reach the striker-cylinder 3 they are knocked off by its floats, which revolve with it in the direction past the burring-cylinder indicated by the arrow. This will be understood by reference to Figs. 5 and 6, in which is shown the plate between two rows of burring-teeth, upon which the fiber rests while the burrs are being knocked off. As the fiber is not deposited quite evenly upon the burring-cylinder from the pickercylinder, but is in places left in bunches upon the surface of the former, these bunches of fiber cover and inclose some of the burrs and prevent their being knocked off by the striker 8. To overcome this difficulty, I mount the toothed worker-cylinder w behind this striker with its teeth in such contiguity to the burring-cylinder as to impinge against the bunches of fiber which mayhave lodged upon the surface of the burring-cylinder and at-the same time to allow the fiber which is spread evenly and thin enough upon the latter to float its burrs and to have them knocked 06 by the striker s to pass by undisturbed. This workercylinder w is made to take hold of and spread the bunches of fiber evenly upon the burringcylinder without removing it therefrom by giving to it a rotation on its axis in the opposite direction to that of the burring-cylinder and at a somewhat slower surface rate of speed than that of the latter, which causes the teeth of the worker-cylinder to lag behind those of the burring cylinder, so to speak, as they pass each other. As the burrs upon the thinner and evenly spread parts of the sheet of fiber carried by the burring-cylinder have been previously knocked off by the striker 8, this spreading out of the bunches of the fiber over these parts by the worker w does not serve to cover over any of the floating burrs as it would if the striker s had not preceded the worker in its operation. Care should be exercised to not have the workercylinder 20 run so much slower in its surface speed than the burring-cylinder as to remove the fiber off from the burring-cylinder; but its speed should be so regulated as to give up or release the hold of its teeth upon the fiber when the latter has been sufficiently spread or drawn out upon the surface of the burring-cylinder. I have found that with com mon wool a difference of surface speed in a given time of three-fourths in favor of the' burring-cylinder gives good results, although this difference must vary somewhat for different fibers of wool.and can only be determined accurately for each kind by experiment. After the worker-cylinder w, I mount O is the long counter-shaft pulley, which drives the machine. From this are directly belted the fan H, brush 1), and picker-cylinder shaft. 011 the opposite end of the latter and the one nearest the observer, as shown in Fig. 1, is attached pulley c, from which are belted the pulley c on the shaft of the burring-cylinder and the pulleys c c on the shafts of the knock-0E cylinders s s, as shown. From the smaller pulley c on the picker-cylinder shaft is belted the double pulley 0 which revolves upon a stud attached to and projecting outward from the face of the frame. One part of this double pulley is belted to the pulley 0 which is upon the shaft of worker-cylinder w. The other part of the double pulley c is belted to the pulley c", which revolves upon a stud projecting from the face of frame A, and has connected to it the pinion e. The latter meshes with the larger pinion c on the end of the shaft of the lower feed-roll F the rotation of which when the fiber passes through revolves the upper one F. Behind the pinion e is a smaller one, attached to the same shaft, as shown in dotted lines, which engages with the intermediate pinion 6 which drives the pinion e on the end of the shaft of the roller f of the feed-apron.
In order to adjust the burring-cylinder B and the worker-cylinder w to the proper distance from each other, I mount the boxes in which their shafts run in slots or grooves in the frame and attach them to the ends of screws a a, which work in nuts 72 n, attached to the frame, so that the screws will revolve in and carry theboxes with them in the usual way. By turning the screws a a, I am enabled to adjust theboxes in their slots. The knockofi cylinder 8 is also adjusted by screw to and nut 07. in a similar manner, while the-knockoff cylinder 8 is adjusted by set-screws a a bearing on opposite sides of its boxes. It will of course be understood that the mounting of the boxes and their screws is the same at both ends of the respective shafts.
In Figs. 3 and 4 is shown a machine for burring in which the picker-cylinder and its fan H are omitted, to which my improvement isapplied. The burring-cylinder B takes the wool directly from the feed-rolls F F and carries it past the knock-off cylinder 8, which strikes off the floating burrs, as before described. The worker-cylinder next draws out the bunches of fiber on the burring-cylinder, and as, in case of these bunches being very uneven, some of the fiber may adhereto the worker w and be drawn away from the burring-cylinder, I provide a doffer-cylinder d, having its teeth projecting in the opposite direction and revolving on its axis at a greater surface speed than the worker 10 and in the same direction, but at a less surface speed than that of the burring-cylinder B. This doffer is so placed on the rear side of worker 10 that its teeth shall be contiguous, both to those of the latter and to those of the burring-cylinder, as shown. In case any great excess in the size of a bunch of the fiber crowds a portion of it upon the worker 20 so that it becomes separated from the burringcylinder it is taken up by the doifer (Z and returned to that cylinder as it is being carried past it on the doffer-teeth. After passing the worker 10 the knock-01f cylinder 5 removes the burrs exposed by it, and the fiber is carried past another worker-cylinder .10, which is set a little closer to the burring-cylinder than the worker w, but moves in the same direction and at the same speed as the latter. This worker reduces and draws out the bunches of fiber which may have escaped the worker w, and in the same way. The knockoff cylinder .9 then removes the burrs exposed by the last worker preceding it, and the fiber is removed from the burring-cylinder, as before. Other workers and knock-off cylinders may be used, with each succeeding one set closer to the burring-cylinder, if desired, and the fiber maybe further evened and burred, as above described, if desired.
In Fig. 3 the driving belts, pulleys, and gears of the machine are shown in outline. The pulley c on the shaft of the burring-cylinder, the pulleys 0 c c on the shafts of the knock-off cylinders, the pulleys c e 0 on the shafts of the workers w w, and doffer d, and the pulley c driving the feed-rolls and apron, are separately belted to suitable pulleys on the counter-shaft overhead, as the lines of belts indicate.
What I claim as new and of my invention 1s 1. The combination, in a wool-burring machine, of the burring-cylinder B, the knockoff cylinder, the worker-cylinder following the same, means arranged to revolve the latter on its axis in the opposite direction from the burring-cylinder at a slower rate of speed, and the knockofi cylinder following the worker-cylinder, substantially as described.
2. The combination, in a wool-burring machine, of the picker-cylinder P, burring-cyL inder B, knock-off cylinder 5, worker-cylinder 10, means arranged to revolve the latter on its axis in the opposite direction from the burring-cylinder at a slower rate of speed, and the knockoff cylinder following the worker-cylinder, substantially as described.
3. The combination, in a wool-burring machine, of the hurling-cylinder B, knock-0E cylinder 8, worker-cylinder w succeeding it, knock-off cylinder 8' following the workercylinder, worker-cylinder w, and knock-off cylinder 8 following the latter, and means arranged to revolve said worker-cylinders, respectively, on their axes at a slower rate of speed and in the opposite direction from the burringcylinder, substantially as described. v
4. The combination, in a wool-barring ma chine, of the burring-cylinder B, the knockoff cylinder 3, the Worker-cylinder w, mounted next after the latter, the dofier-cylinder d,
the knock-off cylinder 5, and means arranged to revolve the doifer-cylinder, the workercylinder, and burring-cylinder, respectively, on their axes in such manner that the doft'ercylinder d shall revolve faster than the worker-cylinder and slower than the barring-cylinder, substantially as described.
