That is, when the shaft 26 is in its uppermost position, the needles just barely penetrate the bristles 36, and thus take a light load therefrom, whereas, if moved to the bottom of the slots, the extreme or heavy load will be taken. By this arrangement, it will be seen that the carding machine can be secured in a fixed position to the knitting machine and the two turnbuckled braces 39 adjusted to prevent any sidewise movement during the operating of the complete machine.

, Carried by the arms 23 and 24 are short arms 40 and 40, which bodily support the return feed drumor roller 41, which in turn is driven by the gear 42 carried by the fibe'r feeding drum 29 and the two gear-s43 and 43 and shaft 44, carried by the arm 40', the

- latter gear 43' engaging the gear 45 carried by the roller 41. .By this means the roller 41 is moved with the fiber feeding drum when adjusted.

The shaft 25 is the main drive shaft for the carding machine, and is provided as sldiown in Flgure 3 with an adj ustably mounte she 48, and the three speed gear change mechanism 49, from a gear meshing with a drive gear 51 of the main driving mechanism 52 of the knitting machine. By this arrangement, the change speed gear mecha-' nismcanbe manually set for the desired speed, so that the carding machine can be operated at three different speeds, low, intermediate and high speed, and thus the fiber feed to the needles can be more definitely set making three different fiber weight fabrics.

, and move in-the directions of and regulated, and the same sizeand character of sliver or slubber can be utilized for The other members of the carding machine may be driven in any desired manner. it be: ing essential, however, thatthey be adjusted the arrows. As shown in. Figures. 7, 8 and 9, a modified form of change speed drive mechanism is illustrated, and one that can be set and locked, or 0 rated automatically from the knitting .mac ine needle cylinder, the fabric formed under the automatic operation having rtions of varying thickness of fibers, an "by means of which different effects may be produced. As there shown, a friction disk 54 is operated by the knitting machine driving mechanism 52', and a shaft 55, tubular atits lower end and provided with a key way, carries a gear 47 at its upper end to mesh with the gear 46' of the main card drum, the jour nal 56 being adj ustably carried by the carding machine frame. Slidably mounted in the lower end of the shaft and rotatable therewith is a shaft 57 whose small friction drive disk 58 frictionally engages the outer face of ar 46, operated through the gear 47,

the drive disk 54, so that motion is transmitted to the carding machine, in accordance with the point of contact relatively to the center of the disk 54. To hold the disk 58 in low speed position, a collar 59 is fixed to theshaft 57, and an extension spring 60, bears against this collar and the lower end of the shaft 55, while to move the disk 58 against the action of the spring and to cause the disk 58 to change its relative position to the drive disk 54, and thus cause the card to be operated at varying increased speeds, a trip lever 61 is journalled at 62, and has a yoke fitting astride of the shaft 57 and engaging the collar 59, so that when the cam or cams 65 carried by the needle cylinder engage the inner end 64 of the trip lever, the lever moves the disk 58 as above described. Should, however, it be desirable to adjust and lock the shaft 57 and disk58 at a fixed speed, the cams are dispensed with and the set screws 66 carried b the shaft 55 engages and hdlds the shaft 57 in adjusted position.

From the foregoin description taken in conjunction with the rawings, it is evident that a universal machine for making knitted pile fabrics of varying weights is produced and that merely by regulating the speed of the miniature carding machine with relation to the speed of the knitting machine, the fiber feed to the needles may be regulated for the minimum to the maximum amount regardless of the size of the sliver or slubber.

Or when a bulk fiber feeding card attachment, such as set forth in'my co-pendin application filed September 25th, 1930, erial No. 484,448 is employed, it is merely necessary to drive said attachment through a variable or speed change transmission to obtain the'desired pile formation in the fabric.

It is also desirable to increase or decrease the width of the fiber feeding drum so that the distance of needle travel through the brush may be increased or decreased, and the consequent amount of fiber received in the needles will be varied. It is also contemplated to employ various shaped hooks in the needles, so that the receiving area for the fibers may be larger or smaller as the occasion may require.

By this particular arrangement, the relative feed in or delivery of fibers to the miniature carding machine may nevervary, or if 'so, very slightly within certain hmits, but
