BLADE FOR KNITTING-WHEELS.

SPECIFICATION forming part of Letters Patent No. 451,376, dated April 28, 1891.

lierial No. 361,007. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT W. GoRMLY, a citizen of theUnited States, residing at Troy, county of Rensselaer and State of New York, have invented certain new and useful Improvements in Blades forKnitting-IVheels, of which the following is a specification.

My invention relates to such improvements; and it consists of the novel construction and combination of parts, hereinafter described and subsequently claimed.

Reference may be had to the accompanying drawings and the letters of reference marked thereon, which form a part of this specification.

Similar letters refer to similar parts in the several figures therein.

My invention relates to the blades or wings of knitting-wheels-such as those commonly known as burr-wheels, sinker-wheels, or other wheels adapted to be used in knittingmachineswherein such wheels are revolved by the cylinder-needles which are brought into engagement with such blades by the revoluble n1ovement of the needle-cylinder, the needles entering the spaces between the blades. In certain kinds of work it is found desirable to prevent some of the needles from entering such spaces, and various devices have been employed to fill such spaces, or partially fill the same, to limit the depth to which the needles can enter. Pieces of metal known as presser-bits have been permanently secured to the periphery of the wheel in such spaces, as in plush-burrs.

My invention consists in providing some of the blades of such wheels each with a presserbit integral with the blade; and the object of my invention is to cheapen the construction of wheels having presser-bits.

In some kinds of work it is desirable to provide a presser-bit on every third space between the blades of aknitting-wheel,w11ile in others presser-bits may be required in every fourth or fifth space. The blades of such wheels are usually inserted in peripheral grooves and made detachable. By having the bits secured to the individual detachable blades the number and position of the presser-bits can be easily varied, as desired, upon the same wheel.

In the drawings I have represented in Figure 1 a view in side elevation of a knittingwheel known as a plush-burr wheel and a portion of the needle-cylinder and needles of a circular-knitting machine, showing the relative positions of the wheel and cylinder when in use, some of the blades of the wheel being removed. to better show my improved blade inserted therein. Fig. 2 is a top plan view of a portion of the wheel detached with the same arrangement of blades. Fig. 3 is a view in side elevation of one of myimproved blades detached. Fig. 4 is a horizontal section of the blade, taken on the broken line 4 4 in Fig. 3. Figs. 5 and 6 are respectively face and edge views showing a modified form of blade.

A is a portion of the cylinder, and A knitting-needles secured thereon.

B is the knitting-wheel, revoluble upon a fixed stud B in the usual manner. The wheel is provided with peripheral grooves B adapted to receive the blades O and O, detachably secured therein in the usual manner. The blades are so arranged upon the periphery of the wheel as to afford the needle-spaces 0 between them.

My improved blade G is made like the other blades C heretofore in use, except that a cut is made in the body of the blade and a portion struck up to form the presser-bit 1),

projecting sidewise from the face of the blade, all as shown in Figs. 1 to a. The portion struck up is made of a width to approximately till the space between such blade and its neighboring blade on that side in the wheel. Such bit may be cut and struck up by suitable dies, such as are in common use for cutting and striking up portions of sheet metal.

D is the aperture formed in the body part of the blade by cutting and striking up the portion forming the bit. I

The form of the bit can be varied by changing the shape of the dies by which the bit is cutand struck up.

When desired, the blade may be formed from a blank having a projecting tongue D as shown in Fig. 5, which tongue is bent up along the dotted line D Fig. 5, to the position shown in Fig. 6 to form the bit.

That I claim as new, and desire to secure In testimony whereof I have hereunto set by Letters Patent, ismy hand this 2(1 day of August, 1890.

As an improved article of manufacture, a blade for knitting-Wheels, having a presser- ROBERT W. GORMLY. 5 bit integral therewith cut and struck up from Witnesses:

the body part of the blade, substantially as FRANK C. CURTIS,

described. E. W. GREENMAN.
