BURR-WHEEL FOR KNITTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 424,314, dated March 25, 1890.

Application filed June 20, 18%9.

To all whom it may concern:

Be it known that I, PETER S. KINsEY, of Newark, in the county of Essex and State of New Jersey, have invented a certain new and useful ImprovementinBurrWVheels for Knitting-Machines, of which the following is a specification.

My invention relates to bu rr-wheels for knitting-machines adapted to produce figured or [0 pattern knitting.

Burr-wheels of the kind referred to have been previously made which comprised blades set obliquely on the periphery of the burrwheel hub, and so secured upon the hub that spaces are left between the blades. After the blades have been secured upon the hub certain of them have had the spaces between them filled up by means of solder, lead, or similar soft metal run in in a molten state, where it becomes a fixture and secures together the blades between which it is run. Burr-wheels thus constructed, when once the spaces between the blades have been filled in by the soft metal, cannot be used for any pattern other than that for which they were originally constructed, for which reason it has been necessary to construct separate burr- Wheels for each separate pattern which was desired. By my improvement I obviate this 0 difficulty, for I so construct certain of the burr-wheel blades that their positions may be changed in any desired manner to produce any given pattern, thus making it possible to produce a great number of patterns with the same burr-wheel.

The invention consists in making certain of the blades of which a burr-wheel is composed with enlargements upon one side thereof, which enlargements form part of or are integral with the blades upon which they are formed, and which enlargements are of such thickness that when the blades are arranged upon the burr-wheel hub the enlargements will substantially fill the spaces between the blades upon which they are formed and the next adjacent blades upon one side. It is of course to be understood that the object of filling certain of the spacesbetween the burrwheel blades is that when the knittingnna chine cylinder containing the needles is re Serial N0.3l5,001. (No model.)

volving such of the needles as come in contact with the closed spaces of the burr-wheel will have their barbs presssd in, so that a stitch will be cast off. Such of the needles, on the' contrary, as come opposite the open spaces between the burr-wheel blades will mesh into such spaces without pressing in the barbs, and from such needles the stitches will not be cast off.

In the accompanying drawings, Figure 1 is a view showing a burr-wheel embodying my improvement in perspective, together with a portion of a knitting-machine cylinder. Fig.

2 is a plan or top view of the burr-wheel. Fig. 3 is an edge view of the same. Fig. 4 1s a transverse section thereof, taken on the line 00, Fig. 3. Fig. 5 is a plan or top View of a burr-wheelembodyin g myimprovement, showing a diiferent arrangement of the burr-Wheel blades than is shown in Fig. 2. Fig. 6 is an edge view of the burr-wheel shown in Fig. 5. Fig. 7 is a side View of one of the thickened blades with the face upon which the thickened portion is formed in front. Fig. 8 1s a transverse section of the blade shown in Fig. 7, taken in the line m Fig. 7 Fi 9 is a side View of a burr-wheel blade of ordinary construction and of uniform thickness. Fig. 10

is a transverse section of the same, taken on the line 00 Fig. 9. Fig. 11 is a perspective of So the burr-hub with the blades removed.

Similar letters of reference designate corresponding parts in all the figures.

I-I designates the hub of the burr-wheel, which may be made, in the usual manner,with obliquely-arranged slits or slots 3 in its peripheral face.

B designates blades of ordinary construction, or, in other words, which are of uniform thickness throughout.

B designates blades having secured to them or formed integral therewith upon one of their sides enlargements e, which increase their thickness, and which extend approximately to the outer edges of said blades, as at 6 Both the blades B and B are to be inserted in the slots 8 and when so inserted will extend obliquely to the axis of the huh.

I have shown a convenient method for securing the blades 13 and B in the hub, con- ICO sisting in providing the upper rearward edges of said blades with locking-bevels l), which engage a recess 6 formed upon the upper side of the hub. In order to lock the blades in the hub, I have shown a plate P, which plate is provided with a central aperture Q, so that it may be passed downwardly over a sleeve T upon the burr-wheel hub. \Vhen in use, the sleeve T is placed upon a supporting arm or bracket A, mounted in a standard S, extendin g upwardly from a table or support T The securing-plate P is adapted to clamp by its outer rim p the inner edges of the blades B B and hold them in position. In order to secure the plate P, I have shown a nut n, engaging the screw-threaded upper portion of the sleeve T. I have also shown a washer VV,haVing a central opening 0 and arranged between the nut n and the plate P. When the nut n is screwed down, it will secure the plate P and prevent displacement of the blades 13 and B 0 designates a part of a knitting-machine cylinder,N the needles thereof, and a web of knitted fabric.

With the parts thus made and arranged, when the blades B and B are inserted with their inner-edges within the slits of the hub and are secured therein, such of the blades B as are employed will close up the spaces between them and the adjacent blades B on those sides of the blades B which are provided with the enlargements 6. Thus series of the spaces between the blades may be closed and such series produced in alternating sequence in the wheel-rim to act upon the needle-barbs to press them in at regular intervals and at intermediate intervals omit to press them in, so that in the one instance the stitches will be cast off and in the other they will not be. By the use of the blades 13' and B so constructed they may be arranged in the burr-wheel to produce a great variety of patterns by their grouping and relative arrangement therein.

That I claim as my invention, and desire to secure by Letters Patent, is

The combination, with a hub having obliquely-extended slots upon its periphery and provided with a recess in its upper face, of blades made to enter said peripheral slots and said recess in the hub top, certain of said blades each having thickened portions or enlargements upon one of its sides, and a cap constructed to be passed down over the hub and upper ends of the blades and secured to the hub, substantially in the manner as and for the purposes set forth.
