JOSEPH DALTON, OF BROOKLYN, E. D., NEW YORK.

Specification forming part of Letters Patent No. 44,403, dated September 27, 1864.

To all whom it may concern.-

Be it known that I, JOSEPH DAL'roN, of Brooklyn, E. D., county of Kings and State of N ewYork, have invented a new and use ful Improvement in Knittingdvlachines; and I do hereby declare that the following is a` full, clear, and exact description thereof,

make and use the same, reference being had t-o the accompanying drawings, forming part of this specifica-tion, in which- Figure 1 represents a -vertical central section of this invention, the plane of section being indicated by the line a' w, Fig. 2. Fig. 2 is a plan or top view of the same.

Similar letters of reference indicate corresponding parts.

r1his invention relates to certain improvements in that class of machines which are known as Daltons KuittingMachines, and in which a cylinder of stationary needles is used with the barbs on the outside, as shown in my patent of May 7,1861. Within this Y cylinder rotates a shaft in unison with a circular table revolving around the cylinder of needles, so that the respective burr-wheels, carried within the cylinder of needles by the shaft, and outside thereof by the circular table, travel around the said cylinder of needles and deposit the yarn in the barbs of the needles, close the said barbs, cast oit' the previous loop, and thus knit the fabric by any of the well-known character of stitches.

This present improvement consists in casting the needle-cylinder solid with the bcd or stand of the machine, so as to save a large amount of stock and of labor requisite with the present arrangement in use prior to this my invention in fitting and securing the cylinder to the bed 5 also, in ruiming' the revolving circular table between the flange of the cylinder and the needle-plates, and thereby dispensing with the oldstationary bed, with the hub of the cylinder, and with the nut required to hold the same in its place, further, in the use of an adjustable collar, in combination with the revolving` table and needlecylinder, in such a manner that any wear in the working-surfaces of the cylinder or table can be compensated -for at any moment, and the burrs are enabled to retain their relative i distance from the needles. Finally, in making the needle-plates adjustable in a vertical direction, so that the same can be readily arranged to bear uniformly upon the inner edge ring in the bearing-surfaces can be compensated for with little trouble or loss of time.

A represents the bed or stand, which is cast solid with the cylinder B and with the l legs C. lhe bed A is perforated in the cenl ter to receive the inner shaft, and it extends l beyond the cylinder, forming a ange which supports the revolving table D, as clearly shown in Fig. 1 of the drawings. The ta le I) is revolved by suitable bevelgear from the driving-shaft, which is not represented in the drawings, and itis provided with a ring or collar, E, the inner circumference of which bears against the cylinder A. Said collar is made in two or more sections, which are secured to the table by a series of screws, a, and between the adjoining ends ofthe several sections of the collar small gaps b are left, so that in case of wear said sections can be closed up. The holes through which the screws pass are oblong slots c, made parallel to each other when but two sections are used, but radial with the axis when more than two sections are used, so that the several sections of the collar can be adjusted toward or from the center of the cylinder as may be desirable. By this arrangement any wear in the bearing-surfaces of the table and cylinder can be readily compensated for, and the gears arc enabled to retain their relative distance from the needles with perfect accuracy. The table D revolves between the flange of the cylinderB and the needle-plates F, which are secured to the outer circumference of the cylinder by screws d. rlhe holes in the plates through which these screws pass form oblong slots c, (see Fig. 1,) arranged so that said plates can be adjusted up and down, and that their lower edges can be kept close to the upper surface of the collar. By this arrangement the bearingsurfaces of the principal parts of my machine can be readily adjusted,

i of the revolving table, and any wear occur-v which will enable those skilled in the art to and the machine can be kept in perfect; worki in combination with the revolvingtnble D ing'order fonany length of time.

I claim as new and desire to secure by Letters Patentl. Casting the l'leedle-eylinder ofaknittingmaelline solid with the bed or stand.

2. Running the revolving table D between the flange of the cylinder B Iand the needleplates F, substantially as and for the purpose specified.

3. The adjustable sectional eollarE, applied i and cylinder B, in the manner and for the pur-- pose substantially as herein shown and described.

4. Making the needle-plates vertically adjustable, for the purpose set forth.
