JACQUARD APPARATUS AND CONNECTED MECHANISM FOR USE IN EMBROIDERING AND OTHER MACHINES.

SPECIFICATION forming part of Letters Patent No. 435,875, dated September 2, 1890.

Application filed July 27, 1886- Renewed July 19, 1889- Serial No. 318,043. (No model.)

To all whom it may concern:

Be it known that we, CHARLES H. WVILL- COX, of New York city, in the county and State of New York, and RUDOLPH Weiss, of Nottingham, England, have invented a new and useful Improvement in Jacquard Apparatus and Connected Mechanism for Use in Embroidering and other Machines, which improvement is fully set forth in the following specification.

This invention relates more particularly to means whereby the cloth'frame and other parts of an embroidering-machine may be operated automatically; but it is not limited to such machines, being applicable,at leastin part, to other purposes and uses; neither does the invention consist in the combination of the said means with the cloth-frame or other parts of an embroidering-machine, butin the means themselves irrespective of the use or the special kind of machinery to which the same may be applied.

Jacquard apparatus, it is well known, is and has long been employed for giving motion to devices of various kinds in looms and elsewhere, and the improved apparatus which forms part of the present invention is believed to have an equal, or even wider, range of usefulness than that heretofore employed. The latter, so far as we are aware, has been adapted to impartdefinite movements onlythat is to say, the movements are all the same length or are multiples of that length-and it is impossible by a mere alteration in the cards to procure whatever length may be desired. The utmost that can be attained is to make the unit of movement very small, and thus approximate the desired length. This, however, involves a multiplication of parts with consequent complication and liability to irregular action. For embroidering purposes the result even then would not be satisfactory, for the pattern would have a harsh and angular effect. In the improved apparatus the cards, or devices controlled by them, act upon inclined planes or their equivalents, and movements in any direction and to any length, not exceeding a certain limit, may be given to the parts which carry the inclined planes without changing the movement of the Jacquard cylinder. It is only necessary so to arrange the device which acts upon the inclined plane or its equivalent that said device will begin its action sooner or later in the movement of the Jacquard cylinder, or upon a different part of the said plane or its equivalent.

It is evident that this improvement could be embodied in different forms of apparatus, but preference is given to an arrangementin which slotted cards are placed on the cylinder of the jacquard,and the part to be moved carries a thin wedge which passes through a slot and is acted upon by the material at the end thereof. The material composing the card may act directly upon the edge of the wedge; but to avoid the wear upon the cards, which would ordinarily be of pasteboard or thin metal, shoes of metal are used. These may be fastened permanently to the card, or they may make a permanent part of the Jacquard apparatus and be used successively with different cards. In the latter case the shoes slide and are provided with projections which enter the slot, and when one of these projections comes to the end of the slot, as the shoe can now move no farther, the wedge is itself compelled to move, and of course imparts motion to the part connected therewith. I

The invention also comprises a mechanism which is put in motion, preferably, by a J acquard apparatus, but it may be by cams or otherwise, for shifting the part to be operated thereby (the cloth-frame of an embroidering machine, for example) in accordance with a certain pattern or design. This new or improved mechanism has a pin or other device movable in all directions in a given plane, and this device, hereinafter termed a shifter-pin, is given a succession of movements away from a given point or center and then back to said point or center. During each outward movement the shifter-pin is made to engage and carry with it a plate, hereinafter termed the pattern-plate; but during its return-movement it is disengaged from said plate. Thus while the shifter-pin is simply moved back and forth within a limited area, the pattern-plate is given a progressive moserves to correct the inaccuracies of the J acquard apparatus when the motions of the p I latter are transmitted through it. WVith such apparatus it is impossible to secure always the precise motion desired, although it is practicable to make the variations very small,

7 so small, in fact, that any one of' them would be inappreciable. If, however, the movements be made progressively, the small variations (should they happen, as they often would, to be in the same direction) are added together, and the error soon becomes manifest. By returning the shifter-pin to a common point or center the movements are rendered independent of one another. Means are used-such as a cone fitting into a circular hole-to correct after each movement any variation that may have resulted from the small imperfections of the Jacquard apparatus. In order to insure a perfect registry at each movement, a pattern-plate is provided in which there are a series of holes arranged in accordance with the pattern. This plate is preferably fastened to the pantograph-arm. The shifter-pin enters a hole in the plate and moves the plate in such a way that another hole is brought into position to receive the shifter-pin for the next movement. This positive connection is very important to the practical working of the machinery, since any slip between the device fastened to the pantograph-arm and the device which is opera-ted by the jacquard and moves said arm would be very likely to disarrange the subsequent operations. The reduction of the motion of the shifter-pin by the pantograph is advantageous in this connection in enabling the holes in the pattern to be separated by suficient material even for the smallest movements.

A further new improvement consists in an automatic stop mechanism for bringing the machine to a standstill when the pattern is finished, or when it is desirable to stop the machine temporarily for any purpose connected with the pattern.

The invention also comprises certain particular constructions, combinations, and arrangements of parts, as hereinafter specified.

Having now explained the principle of the invention, what is considered the best mode of applying that principle will now be described, with the aid of the accompanying drawings, which form part of this specification.

Figure 1 is a plan as seen from behind, and Fig. 2 a back view, partly in vertical section, of a Jacquard apparatus and connected mechanismconstructed in accordance with the invention, parts of an embroidering-machine with which said mechanism is combined being also represented. Fig. 3 is a sectional elevation in a plane different from that of Fig. 2. Figs. 4 and 5 are vertical cross-sections on lines IV and Vof Figs. 1 and 2. Fig. 6 is a detail View of the shifter-pin and pattern-plate, and Figs. 7 to 14: are detail views of the Jacquard apparatus.

The cloth-frame A of the embroidering-machine, supported in any ordinary or suitable Way, is to be moved up and down and right and left in front of the needles, (not shown,) by means of a pantograph system of levers, as common in embroidering-machines. lever-arm 401 of the pantograph is forked, (see Fig. 1,) and the back member is fastened to a perforated pattern-plate R and the front member to a pointer 350. The pattern-plate R is supported between the two upright frames or

standards

90 and 91. The holes in this plate represent the pattern, and they are so arranged that when brought successively to a certain center or fix d point the cloth-frame is shifted to present the fabric in correct position before the needles. The shifter-pin S, by which the pattern-plate is moved, is supported on cross-slides, the one 92, which carries the shifter-pin, being movable in upright ways of the slide 93, and the latter movable in horizontal ways of the frame 91. By the combined movements of these slides the shifter-pin can be moved in any desired direction. The pattern-plate is carried with it or remains stationary, according as the shifter-pin is or is notinsertedinaholein said plate. The shifterpin is setin a holder 94:, being screwed into the same, so that it can be removed at any time. The pin-holder slides in ahole in the slide 92 and in a tubular projection on the inside of the said slide 92, and isconnected by a groove and collar with the end of a lever 95, which is fulcrumed in abracket on the back of slide 92. A compression-spring 96 tends to turn the lever so as to force the pin into the pattern-plate. The pin is withdrawn by pressing in the tail or lower end of the lever, for which purpose there is a small plate 97 suspended above the said end by arms 98 from a fixed bracket. It is swung in to operate the lever. -When the pin is withdrawn, the pattern-plate is held stationary by a presser-foot T at the end of a -lever 107, which is fulcrumed to brackets on the frame 91. The pressing-surface surrounds the shifter-pin at such distance as not to interfere with its movement. There are bearings or projections 988 on the inner face of the standard 90 opposite the corners of the presser-foot to hold the pattern-plate in front.

The action of 'the apparatus is as follows:

The

above or below the other, the slide 92 only will be moved, and if it be in the same hori zontal line the slide 93 will be moved and no independent movement be given to slide 92. The presser-foot moves inward to bear upon and clamp the pattern-plate, and the shifterpin having been withdrawn is returned to the central position. It is then advanced and shifted to give the next movement to the pattern-plate and cloth-frame. The point of the shifter-pin is conical, so that if the hole in the pattern-plate should be slightly out of position it is centered accurately by the insertion of the pin. The longitudinal movements of the shifter-pin are controlled by the cams 100 on the shaft U, which cams act upon the ends of vertical levers 101, fulcrumed at the bottom to fixed brackets and connected at the middle, by means of the rods 102, with the lower ends of the rods 98. Springs 103 return the said parts and retain the rollers at the top of levers 101 in contact with the cams.

The movement of the presser-foot is controlled by the cams 104, which act upon the upper ends of levers 105, connected by rods 106 with the lower end of lever 107, which is divided or forked. The tension-springs 108 return the levers and force the presser-foot against the patternplate.

The cross-slides are each connected with wedges 110 and 111 for the

slide

92, and 112 and 113 for the slide 93. In Fig. 2 the wedge 110 is broken away to show the wedge behind. A connecting-rod 114, jointed at the bottom to the lower end of slide 92 and bent outward at the middle, so as to pass around behind the bearing-plate 97, is jointed at the top to the horizontal arm of the bell-crank or bent lever 115, which is fulcrumed to the upright bracket 116, making part of the Jacquard frame. The vertical arm of lever 115 is connected by slot and pin with the slide 117, which moves in ways of the Jacquard frame and carries the wedges 110 and 111. The similar slide 118, which carries the

wedges

112 and 113, is connected directly with the slide 93 by an arm 119. The arm may be a continuation of the slide 118. In the Jacquard frame there is also a third slide 120, which carries a single wedge 121. It is connected by slot and pin with the lower end of the upright lever 122, fulcrumed upon the front of the bracket 116. The upper end of the lever 122 is jointed to the end of the rod 34. The rod 34: is for adjusting certain weights, (not shown,) whereby the tension upon the threads of the embroidering-machine is regulated. Below the wedges is the Jacquard cylinder V, of eight sides, and with three slots in each side corresponding with the three wedges under the three slides. The shaft of the cylinder is journaled in boxes 123, which slide in ways of the frame. The ends of the shaft project. On one end are fixed the notched wheel 124 and the ratchet-wheel 125. On the opposite end is fixed the eight-sided wheel 126.

Both ends pass through holes in the arms 127 of the yoke IV and slots in the ends of levers 128, but are free to turn therein. The yoke and the Jacquard cylinder are lifted together by the action of the grooved cams 129 upon the levers 128, which are pivoted at the back end in brackets of the machine-frame. The yoke is guided in its up and down movements by the side bars thereof, which travel through lugs 130 on the frame. As the Jacquard cylinder descends, the ratchet-wheel meets the pawl 131 pivoted at the bottom of the frame, and is turned through one-eighth of a revolution. During the succeeding rise of the cylinder the spring 132, which is fastened to the frame at the bottom and at the top, bears against the wheel 126, prevents its turning until the ratchet-wheel leaves the pawl, when the notched wheel 12% meets a dog 133, that enters one of the notches, and thus holds the cylinder positively. The dog is lifted with the wheel. It slides in ways of the standard, making part of the frame. A stop limits its descent, so that it is clear of the notch before the ratchet-wheel is in position to be turned by the pawl. The cards X, connected together in a chain, pass around the cylinder, a pin 13d at each end of the cylinder entering a hole 450 in the end of the card. The cards also are confined between the flanges at the cylinder ends. In each card are three slots. Vhen the cylinder is raised, the three

wedges

111, 113, and 121 enter each one of the slots in the card, and also the corresponding slot in the Jacquard cylinder, and are moved in one direction or the other, according to the position of the slots. In the face of the cylinder are sliding shoes 136, which are arranged in pairs-one pair below the wedge 111 and a second pair below the wedge 113. At the abutting ends of the shoes of each pair are projections, and the ends themselves are inclined, so as to be parallel with the edges of the wedge. When a card is on the cylinder, the projections pass through the slots therein. To allow the projections to enter, the slots are enlarged at the middle of the cylinder. When the cylinder is raised, the wedges 111 and 113 each enter between the ends of the corresponding shoes and push one or both outward until the projection on one of them reaches the end of the slot. As it can move no farther, the wedge is pushed in the opposite direction, pushing the other shoe ahead of it and moving the shifter-pin, the pattern-plate, and the clothframe. It will thus be seen that the end of the slot nearest the middle of the cylinder alone has an effect upon the wedge, and that the nearer it is to the middle the farther the wedge is moved, because as the positive action begins nearer to the point of the wedge itextends througha greater distance. The movement of each wedge depends solely upon its own slot. One or both of the wedges may be moved. A horizontal movement is given to the cloth-frame if the wedge 113 only be IIO moved, a vertical movement if the wedge 111 only, or an oblique movement if both be moved. Whether the movement of the clothframe shall be right or left from the previous position depends upon which end of the slot .for wedge 111 is nearest the middle. If the outer (right hand, Figs. 1 and 2) be nearer, the pattern-plate and cloth-frame are moved to the left, as represented in those figures. If the inner end be the nearer, the cloth-frame is moved in the opposite direction. If they are the same distance, the cloth-frame has no horizontal movement. The position of the slot for wedge 113 determines whether the cloth-frame shall be moved up or down. If the outer end be nearer the middle, the frame goes up. If the inner end be the nearer, the frame goes down.. If both are the same distance, there is no vertical. movement. Then the cylinder descends, the shoes are pushed in by the levers 137 as fast as the receding wedge permits. Each of these levers is fulcrumed at the bottom, and is combined with a spring 138, that tends to move it inward. At the top the lever is broad, so as to bear upon the ends of the shoes. After the shoes leave the wedges, which is just before the cylinder commences to turn, the ends of the shoes pass behind the fixed plates 139, which retain them in a central position until they are again pushed out by the wedges on the ascent of the cylinder.

The fixed plates form the end bearings to the Jacquard cylinder. The yoke WV being drawn down with the cylinder, the cross-bars 140, or one of them,comes in contact with the corresponding edge of the

upper wedges

110 and 112 and returns them, together with the shifter-pin, to the central position. The wedge 121 acts directly upon the end of the slot in the card, or rather against the shoe latl, which is there fastened to the card. The sliding shoes are not used, because it is not convenient to return the wedge at each descent of the cylinder, and if not returned the shoes being returned by the levers 137,0ne of them would on rising again come square against the point of the wedge. It is evident, however, that a second wedge could be placed on the top of the slide 120, and then the sliding ing shoes could be used. In that case, of course, the machinery should be such as to admit of a return of the wedge at each descent of the Jacquard cylinder. v

Instead of placing the sliding shoes on the cylinder under the cards they may be placed above the same and be connected with the wedges or the slides that carry them. This arrangement answers equally well whether the slides that carry the wedges are or are not returned. It is shown in Figs. 13 and 14. The shoes 142 slide in grooves 14.3 in the wedge parallel with the edge thereof. The shoes are thicker than the wedge. The slot in the card is equal in width to the thickness of the shoes, and the slot in the cylinder equals the thickness of the wedge. WVhen,

therefore, the'cylinder rises, the 'shoes pass through the card and rest upon the face of the cylinder. Further rise of the cylinder forces the shoes toward the ends of the slot in the cards, the wedgepassing through the slot in the cylinder. A pin 144 limits the movement of the shoes downward on the wedge.

It is not essential to use sliding shoes for any of the slots, but each slot could be protected by a stationary shoe-such as 141- and, except for the wear upon the end of the slots, shoes of all kinds could be dispensed with. If the cards were of thick metal, as they may be, shoes would be of less importance.

The stitch-forming mechanism of the e1nbroidering-machine may be operated from a pinion 150 on the shaft U in order that the proper timing relatively to the Jacquard mechanism may be secured. The shaft U is driven bya belt on the fixed pulley 160 through the gears 161 and 162. There is a loose pulley 163, onto which the belt is shifted when it is desired to stop the machine. The belt-shipper consists of a sliding shipper-bar 164:, having the usual yoke or fork to embrace the belt. A spiral compression-spring 165 is confined between the plate 166 at the end of the bar and a bracket 167 on the frame. The pressure of the spring is resisted by a trip-pawl 168 in the form of a bell-crank pivoted to the bracket 167, with one arm in the path of lug 170 on the shipper-bar. The other arm of the bell-crank is connected by a slot and pin with the lever 171, fulcrumed on the machine-frame. A'Wire 172 is fastened at one end to theouter extremity of the lever and is led around the

pulleys

173 and 174 to the end of the upright lever 180, fulcrumed in a bracket on the standard of the embroidering-machine. Between the pulleys 173 and 174: the wire is fastened to the front end of lever 175, which at the rear end is fulcrumed in a bracketof the Jacquard frame. A rod 176 is jointed to the under side of the lever and hangs down just above the hole 177 (see Fig. 10) in that face of the cylinder which at the time is uppermost. If the card has a corresponding .hole 455, the rod 176 passes freely through both, and the lever 175 is not affected. WVhen, however, a card comes uppermost that has no perforation at that point, as shown in Fig. 10, which occurs at the end of the pattern, or whenever a hand operation is to be performed, the solid card comes into contact with the end of said rod, and the cylinder lifts it and the lever 175, drawing on the wire 172, turning the lever 171 and trippawl 16S and releasing the shipper-bar,whereupon the spring 165 expands and moves the belt to the loose pulley. The shipper-bar can be returned by means of the lever 178, fulcrumed to the frame and jointed at the outer end to the shipper-bar. A compression-spring 179 returns'the lever 171 and the trip-pawl 168 when the lever 178 is moved.

The lever lSO is provided in order that the V 172 would terminate at the lever 175, and a stop uphold the said lever in its normal position.

In order to prepare the pattern-plate and cards for the Jacquard cylinder, the following mode of procedure is recommended. A pattern is made on paper, as customary in preparingthepattern-card for embroidering-machines. This paper 460, Figs. 2 and 4, is fastened to the standard 90, so that the pointer 350, fixed to the front member of the pantograph arm 401, can move over the face thereof. The pointer 350 is brought to the starting -point of the pattern, and thereupon the cross-slides are returned to the central position by dropping the Jacquard cylinder and yoke. The shifter-pin is then removed from the holder, a drill is introduced through said holder, and the first hole in said pattern-plate is bored. Preparatory to borin g the next hole the pattern-plate R is moved in the proper direction and to the proper distance, as indicated by the pointer 350 on the pattern-card 4:60. The holder being now in the central position, as before, the drill is advanced to bore the second hole. The boring of the third and succeeding holes is then offected in like manner, the pattern-plate being shifted so that the pointer is successively opposite the different points on the patterncard 460. Of course after each boring the drill is withdrawn from the hole made by it. After the boring of each hole in the patternplate one of the cards of the Jacquard apparatus is or may be prepared and tested to see if it is rightly prepared before the next hole is bored in said plate. For this purpose, after, say, the first hole has been bored, the drill is removed and the shifter-pin, or a pin of the same size, is slipped into the holder. The operator in front of the pattern-card 460 then moves the pointer 350 one step and places it upon the pattern where the next puncture is to be made. The pattern-plate R, as well as the cloth-frame, of course follows the movement of the pointer, and as the shifter-pin or its substitute projects into the pattern-plate and connects it with the crossslides said cross-slides and the

slides

117 and 118, which carry the wedges, are moved also. The bottom wedges, which, in order that they may be removable, are bolted to the slides, as shown in Figs. 7 and 8, instead of being made integral therewith, as represented for convenience in other figures, have been removed and replaced by markers 351. (Shown in Fig. 9.) These markers consist or may consist of a plate having at the ends two depending projections 352 with chisel-points. The distance between the chisel-points is equal to the length of the slots in the jacquard. After the slides have been moved the Jacquard cylinder, on which a blank card has been placed, is raised untilthe card comes into contact with the chisel-points and is indented by them. The indentations mark the position of the two .slots. The blank card has, of course, a hole in the middle to fit over the projections on the shoes 136. After the card is marked the Jacquard cylinder is lowered, the marked card removed, and the two slots punched, and the card replaced on top of the cylinder. The markers are now removed from the slides, the wedges 111 and 113 are replaced, the pointer 350 is moved back a step, which again brings the hole in the pattern-plate central, and the shaft U is turned. As the shaft revolves, the pin enters the hole in the pattern-plate, the Jacquard cylinder is lifted, the wedges 111 and 113 enter the newly cut slots in the card,

and the cross-slides, shifter-pin, pattern-- plate, pointer, and cloth-frame are all moved by the action of the card on the wedges. If the operations have been properly performed, the pointer should bemoved exactly to the position it before occupied when moved by hand. If not, the source of error should be traced and the proper correction made. If the machine is in proper order, the error will be in the card, and may be corrected by altering the card, or, if this be not practical, by making a new one. If the pattern-plate be moved too far, it will only be necessary to cut that end of theslot which is nearest the middle of the card, so as to elongate the slot until the motion is reduced to the desired extent. If, however, the pattern-plate be not moved far enough, it would be more difficult to alter the card. It may therefore be well, unless the punching is very accurately performed, to move the pointer, in marking,a very short distance, both in a vertical and in a horizontal direction, beyond the proper point on the patterncard, so that the operative end of the slot, which is always that nearest the center, may bycutting out be adjusted to move the wedges and slides the proper distance. After the operation of the slotted card upon the wedges is satisfactory the shifterpin or its substitute is moved back to the central position, the operator in front of the pattern-card holding the pointer stationary. The shifter-pin is then removed, the drill is inserted in its place, and the second hole is bored. The shifter-pin is now inserted in the second hole and the pointer is moved to the third place on the pattern-card. The markers having been placed on the slides and a blank card on the Jacquard cylinder, the latter is lifted to mark the slots. The cylinder is then lowered, moving the cross-slides and shifterpin to the central position, the card is taken off the cylinder, has the slot punched therein, and is then replaced. The wedges having been replaced on the

slides

117 and 118, the pattern-plate is moved back one step, so that the second hole in the pattern-plate is in the central position. Upon turning the shaft U the shifter-pin will enter this hole, the J acquard cylinder will lift the newly-punched card, and the wedges while being actedupon by the cards will move the shifter pin and pattern-plate in the required direction. If

the operation is satisfactory, the pattern-plate moved at each step, as can be seen by watching the movement of the pointer over the pattern-card 460.

In the foregoing description it has been supposed that the wedge 121 is removed from the slide 120 in order not to be in the way. The slots for this wedge may be marked in the following manner: The operator: ascertains by experiment or calculation the position of the tension weights for each stitch, then, placing a marker on the slide and adjusting the weights, the points of the marker will indent the card on the Jacquard cylinder when it is raised. The, slot can then be punched. The marking of the slots for adjusting the tension-Weights can be efiected at the same time with the marking of the other slots, or

before, or subsequently.

Nothing has been said heretofore of the means for disposing of the chain of cards that hang from the cylinder, since the ordinary means may be used for the purpose. In the drawings an inclined track 4125, which is one of the ordinary means for supporting the chain, is shown. At intervals in the chain there are cross-rods which project beyond the cards, and when not upheld by the cylinder the ends of these rods rest upon the track and travel down it, so as to be out of the way of the cards, which are continually delivered from the front of the cylinder after they have acted upon the wedges.

Having nowfully described our said invention and the manner in which the principle thereof may be applied, we would observe that we do not limit ourselves to the details hereinbefore given, since it 'is evident that these may be varied within wide limits while employing substantially the same principle; nor dowe limit ourselves to the use of all the improvements in combination, although it is designed thus to use them, and the combination itself forms a special feature of invention, since it is evident that one or more improvements or parts of the invention might be used separately; but

In a Jacquard apparatus, adevice-such as a wedge, for example-adapted to be acted upon by the cards of said apparatus, in combination with a series of cards having the part which acts upon said device differently arranged in the several cards, so that they act upon difierent points or portions of said device and give to it different movements, substantially as described. 7

10. The combination, with the Jacquard cylinder, of the chain of slotted cards having thelike ends of corresponding slots in different posit-ions in the different cards, and one or more wedges or devices, each having an edge or extended surface which is acted upon by the said cards at different points, according to the position of the said slots, substantially as described,

11. The combination, with the shifter-pin and cross-slides, of wedges connected with said slides, respectively, the Jacquard cylinder, and the cards having each slots which act upon said wedges simultaneously, substantially as described, so that the said shifter-pin has a movement the resultant of the two movements effected by the card, as set forth.

12. The combination, with one or more wedges, the Jacquard cylinder, and the slotted cards, of the shoes for protecting the ends of the slots, substantially as described.

13. The combination, with one or more wedges, the Jacquard cylinder, and the slotted cards, of the sliding shoes forming a permanent part of the machine, in contradistinction to shoes attached to the cards themselves, substantially as described.

14:. The combination, with the shifter-pin and cross-slides, wedges, Jacquard cylinder, and slotted cards, of the cam and connections for raising and lowering the Jacquard cylinder, the yoke connected with said cylinder, and the cam and connections for withdrawing the shifter-pin during the descent of the said cylinder, substantially as described.

15. The combination,with the presser-foot, the shifter-pin, the cross-slides, the wedges, the Jacquard cylinder, the yoke, and the slotted cards, of the cam and connections for operatin g said parts, substantially as described.

16. The combinatiomwith the Jacquard cylinder and cards, of the yoke movable with said cylinder, and the devices, such as wedges, to be acted upon by said cards and said yoke, respectively, substantially as described.

17. The combination,with the J acquardcylinder, of the levers or arms for raising and lowering it, the ratchet and pawl for turning it, the polygonal or eight-sided'wheel, and the spring for retaining it in the position to which it has been turned during the lower part of its course, and the notched wheel and dog for holding it in place in the upper part of its course, substantially as described.

18. The belt-shipper, the spring for moving the same, and the trip-pawl arranged as an obstruction to the movement of said belt-shipper 11 nderthe influence of said spring, in combination with the jacquard, the rod arranged to be acted upon when the proper card presents itself, and the connections between said rod and the trip-pawl, substantially as described.

19. The method of preparing the patternplate with holes by supporting the same in front of a holder for the drill, advancing the drill to bore the hole and then withdrawing it, shifting the pattern-plate in the direction and to the distance indicated upon a patterncard for the succeeding hole by a pointer connected with said pattern-plate, then advancing and withdrawing the drill, and so continuing until the holes for the desired pattern have been bored, substantially as described.

20. The mode of marking the cards for the jacquard by placing the blank card on the Jacquard cylinder, and having replaced the wedge or device to be acted upon by the cards by a marker, shifting the said marker into the position to be occupied by the wedge at the end of the movement to be given by that card, then lifting the cylinder and card against said marker, and repeating the operations for the several cards, substantially as described.
