4To all whom, it may concern,.-

' Be it known that I, FoR'IUN NEvEUx, manufacturer, residing at San Ambrogio, near l Turin, in the Kingdom of Italy, have invented ming and sewing fabrics, and has for its obknives.

is an end elevation.

ject to provide an efficient device of the aboveindicated character, as will appear from` the detailed description following hereinafter. The features of novelty will be pointed out in the appended claims. l

In the accompanying drawings, Figure 1 is a vertical section on line 1 1 of Fig. 2, which is a plan of the preparatory machine. Fig. 3 In each of these three figures sundry portions are removed or broken away. Fig. 4 is a detail view of the cutting- Fig. 5 is a front elevation of the ksewing-.machine with sundry portions broken away, and Fig. 6 is a plan of the same. Figs. 7 to 11 are detail views. Figs. 1 to 4and7 to 11 are similarly lettered, and the same lettering applies to the comb in all figures. The mechanism for preparing the sewing consists of the comb 1, fixed to'the bed-'plate V 2 of the machine, and the device for cutting the edges and brushing away the cuttings, which is supported on a movable plate 3. This plate is guided by four grooved rollers 31', which run on rails 32, fixed to the bed-plate, and is moved by the engagement of a pinion 41 on a vertical spindle 42 with a rack 4, also fixed to the bed-plate.

` The needle-comb 1 consists of recessed needie-points 10 of somewhat wide angle, the

stems 11 of which are set in holes in a bar 12 The plate 3'carries a bearing 5, in which is journaled the driving-shaft 51, carrying the pulley 52, the Worm 54, the cam 55, and the circular knife 53. This latter cooperates with a straight horizontal knife-blade 56, which is fixed to the plate 3.

When shaft 51 is rotated, the worm 54, engaging with the worm-wheel 43, rotates the spindle 42 and through the latter the pinion 41, which thus causes plate 3, with the whole apparatus thereon, to travel'slowly, inasmuch as this pinion engages with the fixed rack 4. During this movement the knives 53 56 cut off the edge of the fabric which is placed on the comb 1. When the edge has been cut olf, the fabric must be pressed down onto the needle-comb to x it securely on the needlebar. For this purpose the bearing 5 has an arm 21, Which carries a horizontal bar 24, which is adjustable vertically bymeans of a nut 22. This bar 24 carries two rollers 25 and has curved and rounded ends 26. It holds the fabric closely behind the needle-comb and to some extent presses it down thereon. The rollers 25 then lie closely on the needle-bar.

In this position the edge of the fabric is brought against the brush 6, which is xed to the hollow shaft 60. This'shaft can rotate in bearing 61, but is axially immovable. It is mounted on the non-rotating slide-rod 62, which receives a reciprocating movement from cam 55, being for this purpose pivoted at 63 to a bar 64, oscillated by the cam, Fig. 7. A pin 65 on slide-rod 62 engages in a screw-shaped slot 66 in the hollow shaft 60, so that the longitudinal reciprocation of sliderod 62 is' transformed into an oscillating motion of the brush 6. This motion of the brush removes all the ends of thread from the edge of the fabric, so that the pieces are made ready for` sewing. The bearings of the brush 6 are uprights on a plate 67, which can be adjusted in position on plate 3 by means of a nut-and-screw spindle 68, as shown in Figs. 2 and 3, so that the brush can be brought'nearer to or farther from the edge of the fabric.

The screws 69 serve to clamp 'they plate 67. The' return movementof the plate 3'is veffected* by the pinion 46l engaging with rack 4. This rial to be sewed has been thus put into position on the needle-comb, the latter is transferred to the sewing-machine, where the pins 17 on the needle-bar fit into corresponding holes 210 in a bar 20, fixed in front of the sewing mechanism. To form the stitches, the plate 23, carrying the sewing mechanism is moved parallel to the bar 2O along two guiding-rails 220, fixed to the bed-plate 7. For this purpose a pinion 250 engages with a rack 240 and is driven by coupling a disk 28 on the upper end of its axis with a loosely-mounted worm-wheel 27 by means of a pin 260. The wheel 27 is driven by the worm 29.

The sewing mechanism may be of any approved type, provided it is of suitable dimensions. A simple chain-stitch machine may be used with advantage. The driving-shaft is journaled in uprights on the plate 23 and is driven by the pulley 71. On its front end are the loop-hooks 72 for forming the chain-stitch. The needle 73 `in its holder 74 moves up and down correspondingly with the forward movement of the whole mechanism, so that it descends each time into the recess or groove of a needle 10 and makes a stitch which liesagainst the front angle of the bend of the needle 10. The movement of the plate 23 is so timed that the advance or feed for each complete reeiprocation of the needle 73 is equal to the distance between two adjacent needles 10. The pulley 71 is driven by a horizontal rope 280 whenever the roller 281 presses the said rope upon it.

In order that the mechanism for preparing the material may be reciproeated by hand, the worm-wheel 43 is mounted loosely on spindle 42. By raising the wheel the coupling 420, which previously connected it with the spindle 42, is disengaged, and if the hook 421 be turned over the pin 422 in the head of the spindle the latter may be turned in either direction by means of the handle 423, the wheel 43 being then out of engagement with worm 54.

Now what I claim, and desire to secure by Letters Patent, is the following:

1. The combination of a stationary rack and stationary guides parallel therewith, a frame arranged to travel along said guides, a stationary comb or work-holder, pinions engaging said rack and mounted totravel with the frame, a drive-shaft journaled on the frame, connections from said shaft to the pinions to drive 05 them in opposite directions, means for throwing one pinion or the other into operative connection with the drive-shaft, and fabric-working mechanism carried by the frame.
