This sprocket 44 is provided with teeth 45 on its righthand face. Between the sprockets 44 and 39- is a clutch member 46 keyed to the shaft to slide thereon and to rotate the shaft. The clutch member46 is carried by a jaw 47 and is provided on its opposite faces with clutch teeth 49 adapted to engage and cooperate with the clutch teeth 41'and 45 in its respective operative positions. The clutch member 46also has a neutral-position in whichit is out of engagement with both sets of teeth-'49 on the respective continuously rotating sprockets 39 and 44.
The jaw 47 is shown as carried by a rocking lever or arm'50 pivoted at 51011 a bracket 52 on the machine frame, the end of the lever on'the opposite side of the center 51 of the jaw 47 being connected at 53 to a controller cord or-wire 54. I
In accordance with-the preferred form of the invention illustrated, the feed-belts 8 and 9 are driven at their ends near the center of the table'by-pulleys 14 and 19' and at their ends'remote from the center 'of' the table, i. e., at therightfand ,ileft beneath the, cloth rolls 6 and 7 ,to prevent slipping of the belts they are preferably provided with two drive pulleys at each end of the table,
which pulleys support the feed belt beneath the cloth rolls 6 and 7 the pulleys at the right end of the table being indicated, in accordance with the invention shown, by reference characters 11 and 12 and at the left end of the table by reference characters 22 and 24. These rollers or pulleys as they are described, 11, 12, '22, 24, notonly support the cloth rolls 6, 7, but enable'the cloth to be fed from the rolls. at the speed -0f the corresponding belts 8,9.
The pulleys 11 and-12 at theright, in the form of the inventionshown, are provided eachwith sprockets 55 and 56, respectively,
secured to the pulleys and engaged and drivbevel gear 36 in turn carries en by a chain 57 which is, in turn, driven by a sprocket 58 mounted on or secured to worm wheel or gear 59 engaged and driven by aworm 60 on the shaft 40.

. The second feed belt 9is driven in a manner precisely similar to the manner of driving the belt 8. In the form of the invention shown, the drive pulley 19at the end of the traverse of the feed belt 9 near the center of the machine is provided'with a sprocket 68 secured thereto or to the. shaft of the pulley 19. This sprocket is engaged and driven by a chain 69 whichiis, in turn, driven by a sprocket 70 rigidly connected to a worm wheel 71 which is engaged and driven by a worm 72 mounted on and secured to the shaft 40. The pulleys 22and 24 at the left end of the machine which are located beneath the cloth roll 7 at this end are each providedat one end with a toothed sprocket 73 and 74 respectively, the sprockets being secured to the respective pulleys to rotate herewith and drive the pulleys. The sprockets 73 and 74 are"engaged by achain 75 which is, in turn, engaged and driven by a-spr'ocket 76 secured to a worm wheel 77 to rotate therewith, thewormfwheel 77 being, in turn, engaged and driven by a worm 78 on the shaft 40.
In the form of the invention shown, there are, as aforesaid, two feed belts 8' and 9 spaced apartatthe center to provide for the operation of the sewing machine 20, as hereinafter described. 'To support the material between the-belts 8 and 9 suitable supportingmeans' is provided, the same being movable with the machine and, in the form of the invention shown, being in the form of a sewing machine apron 112 to be more particularly described.
The machine is also adapted for use in matching-a plurality of layers of cloth, the cloth being fed from the roll '6 to the roll 7 by means of feed belts 8, 9, running over the table '10, as already described. In this connection it should be understood that the matching operation consists in so assemb ing a plurality of layers of cloth so as to bring the corresponding portions of the figure or pattern on the respective layers into registration and securing the respective layers of cloth together in "this relative position by sewing or otherwise at suitable intervals. To this end the machine, in the form shown, is provided with cloth holding means 115 and IIGQXtQIldiIlg transversely of the machine, preferably at right angles to the feed for the full width of the path of material or fabric, the said securing means and 116 respectively being placed immediately adjacent the end of the corresponding belt and on each side of the apron 112.
In the form of the invention shown, the cloth holding means consists in each instance of a series of needles or pins 115, 116, each series being arranged in a line extending across the path of the material, as aforesaid, the needles being upright or substantially upright with the points uppermost. WVhile this type of cloth holding means has been used in the machine as developed, other cloth holding meansmay be substituted.
The lines of cloth holding pins or needles 1'15, 116 are mounted each line on transverse bars 117, 118, respectively, supported on the machine or table in any suitable manner,
whereby they may be conveniently moved into and out of operative position.
In the form of the invention shown, these bars 117, 118, see particularly Figure 1, are mounted in suitable guides 119 to move up and down in a vertical direction, the bars being actuated by means of links or connecting rods 120 pivotally connected at one end to the crank disks 121 and at the other end to the bars 117, 118. The crank disks, in turn, may be secured to worm gears 122 driven by worms 123, which may be rotated in any suitable manner as by means of hand cranks 12 i and 126. A half turn of the disks 121 moves the crank pins 125 from the top position, in which they are shown, and in which the pins are raised in operative position to the bottom position in which they are withdrawn, and vice versa.
The matching mechanism also includes a sewing machine 20, already referred to, which sewing machine is mounted to move transversely of the table between the adjacent ends of the feed belts 8 and 9, the apron 112 already referred to being connected to the machine to move into and out of sup porting position taking the place of the ma chine table, the latter is advanced and retracted, as hereinafter described.
The sewing machine is most conveniently actuated by means of an electric motor 131 mounted on the machine to move therewith, as hereinafter described, the motor being connected by a flexible cable 132 to any suitable source of electricity, not shown. To move the sewing machine or cloth fastening head back and forth transversely of the table to fasten the cloth in matched relation, as already outlined, a toothed rack 133 is provided at the side of the table and directly beneath the path of the fastening head or sewing machine, he rack extending to the left in Figure 4 a little beyond the posit-ion of the machine as illustrated. This skew or inclined teeth 13 1, is engaged by a skew gear mounted on the sewing machine on an axis parallel to the rack, though the exact details of this device for feeding the cloth fastening head or sewing machine are not essential to the invention. The skew gear 135 is carried by a shaft 136 which is driven by means of bevel 137 on the shaft 136, and 138 on an upright shaft 139, which carries at its upper end a bevel gear 1 10 which meshes with a bevel gear 1411 on the needle shaft 1 12 in the arm 130 of the sewing machine, which needle shaft, in the form of the invention shown, is driven by a toothed gear 14. 1 engaged by a pinion on the motor shaft. The needle shaft 1&2 drives the sewing machine needle bar 116 in any suitable manner by n'ieans of crank disk 147 having a 011L113 pin 1%8 connected by a link 1 19 to the needle bar 146.
The presser foot 150, being actuated in the usual manner by a spring 151 which presses it downwardly on the cloth, is raised to inoperative position by means of a cam 152 controlled by a cam, lever 153 which is swung upwardly to rai e the presser foot and rotated in the opposite direction to permit the presser foot to move downwardly in response to the action. of the spring 151.
In order that the sewing machine 20 may be moved manually and independently of the machine drive, into and out of operative relation to the table as hereinafter described, the rack 133 is mounted to move vertically, the table having vertical guides suitably supported on the table frame and the rack 133 being provided, in turn, with vertical followers 161, which slide in the guides and the rack 133 is moved up and down into and out of operative relation with the gear 135 by the following mechanism, consisting of rotary crank disks 162 provided with worm gear teeth 163 engaged by worms 16 1 on the 'worm shaft 165.
The shaft 165 is actuated at the will of the operator by means of a hand wheel 166 at the right in Figure 4c. The disks 162 actuate connecting rods or links 167 pivotally connected to the rack 133 at 169 and to eccentric wrist pins 168 on the disks 162.
In the operation of this mechanism the rack is moved up and do m. by the rotation of the hand wheel 166 rotating the crank disks 162 back and forth through an arc of 182 degrees or less, depending upon the throw of the crank pins and the distance through which it is found desirable to move the rack.
To support the cloth when the cloth fastening head or sewing machine is withdrawn, as illustrated in Figure l, the apron 112 has been provided. This apron may be in. the form of a strip of canvas or equivalent material which may be stiffened by battens 170 spaced laterally of the machine and extending in the direction of the feed,
' KOO secured to the canvas in any suitable manner. This apron, in the form of the invention shown, is secured at one end to the forward end of the cloth fastening head or sewing machine table 171' at 172, see Figure 4, the apron being passed to the right in Figure 4 between the ends of the belts 8 and 9 as illustrated inFigure 3, and let over a roller 173, see Figure 4, mounted in suitable hearings on the table, the end of the apron being drawn downwardly by means of a weight 174 secured thereto, or any equivalent means whereby the apron is held sufficiently taut to support the material between the belts 8 and 9. The apron is thus held flat and caused to close the table 10 between belts 8 and 9, passing downwardly over pulley 173 as the sen-'ingmachine advances. f
Though the machine may be. used in matching several thicknesses ofcloth, its most frequent use is probablyin matching the two thicknesses of a single piece of clouble width material. For this purpose the cloth holding'means, i. e., needles 116, on
' the side of the sewing machine remote from the cloth roll from which the cloth is being fed, are'first raised as by rotating the hand crank 124, bringing them to the position shown in Figure 1, or the needles may be raised after the cloth has been placed in matching position and relation, as hereinafter described, the cloth being held for this purpose.
Assuming that the needles have been raised in operative position, as already suggested, the double width cloth, folded once upon itself,'being supplied from the roll 6, is drawn forwardly over the table and the lower thickness of the cloth being spread smoothly on the table is pressed down on needles 116, which serve to hold it in position fully extended and fiat on the table. The forward end of the cloth is at this time slightly forward of the needles 116 and the cloth fastening head or sewing machine 20 is withdrawn, the apron 112 being advanced as shown most clearly in Figure 3. The lower thickness or layer of cloth is thus extended and fastened, it being understood that the cloth is folded laterally forming a longitudinal crease substantially in the lateral center, the fold being'partly opened so'the lower thickness can be manipulated in the manner just described. The top thickness or layer is then folded over and laid on the bottom thickness and pressed down on the needles, the longitudinal fold being, if necessary, slightly displaced to match the figure or stripe, i. e., to bring it into registration. The cloth may be then held in position and needles 115 raised by turning crank 126, thecloth being, if necessary, pressed down about theneedles. The two thicknesses 'of cloth are thus held in matched relation in the path of the sewing machine 20 by the pinsor needles 115, 116. At this time the sewing machine 20 is assumed to'be withdrawn to the left in Figure 4 to the extremeposition a little further fromthe table than the position illustrated. At this time the rack 133 is lowered by operation of the hand crank 166 which rotates the disks 162 by way of the worms 164, drawing the links 167 connected to the rack downwardly, the rack being guided, as aforesaid, byfollowers 161' and the guides 160. Y
The machine being in theleft hand position described, the presser foot 150 would, if the machine has just been withdrawn from operation, ordinarily be already in raised position, otherwise, it is raised by operation of the hand lever 153, the same being thrown to elevated position. The sewing machine is then moved to the right in Figure 5, the material being held, if necessary, by hand in addition to the needles. In moving the machine the handle 180 is grasped by the hand of the operator and it is drawn forward or to the ri ht in Figure 4, until the presser foot 150 comes over the edge of the material, which is held in proper position under the presser foot by the operator who wouldthen release the presser foot by lowering the hand lever; 153, rotating the cam 152 to the position shown, in which position the presser foot is moved downwardly by the spring 151 in accordance with the regular operation of this device.
Therack 133 is then raised into mesh with the skew ge'ar135, the hand crank 166 beingturned ordinarily in the opposite direction about half a revolution for this purpose. The motor 131 is then placed in circuit by closing the switch 182, the same being controlled, by a sliding rod 183 having a handle 184 at the front of the machine. The motor 131 not only operates the sewing machine but feeds it forwardly at a speed proportionate to the speed of the needle, the feed of the machine being through the connections 140,139, 138, 137, as already described, to the shaft 136 of the skew gear 135 which engages the rack 133.
The machine moves in this way directly across the web of cloth, sewing the plurality of thicknesses held by the pins 115, 116 to 'gether, a line of stitches or any suitable faschine, In this connection it may be noted I that the machine is, in the form of the invention shown, carried on rollers 185, 186, moving on ways 187.
By the means described the machine and the feed are stopped automatically when a line of stitching has been placed transversely of the material between the needles. The presser foot is then raised by engagement of the hand with the lever 153, the rack 133 is lowered, as aforesaid, and the machine is returned to initial posiion manually by engagement of the handle 180. The cloth is then moved forwardly for a suitable interval and-matched as already described, the various layers being secured in matched relation by the pins or needles 115, 116, and the sewing operation is again performed. When the forward end of the material can be wrapped around the shaft 5, the material may be fed by taking up on roll 7 and letting off from roll 6.
I have thus described'specifically and in detail a machine embodying the cloth matching means of the invention in order that the construction and manner of operating the same may be clearly understood, however, the specific terms herein being used descriptively rather than in a limiting sense, the scope of the invention being defined in the claims.
