JACQUARD MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 507,635, dated October 31, 1893.

I Application filed February 4, 1893. Serial No. 461,007. (No model.) I

To all whom it may concern.-

Be it known that I, OTTO W. SCHAUM, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Jacquard Mechanism for Looms, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to Jacquard apparatus for looms and particularly to a Jacquard apparatus of the kind invented by John Zimermann and described in his pending application, filed May 6, 1892, Serial No. 432,086, my presentinvention beinganimprovementupon the said Zimermann machine, the object being to improve and perfect the same.

The nature of my improvements willbe best understood as described in connection with the drawings in which they are illustrated,

said drawings illustrating a Zimermann machine provided with my improvement-s and modifications.

In the drawings, Figure l is an elevation showing part of a power loom and the Jacquard apparatus connected therewith. Fig. 2 is a side elevation of the jacquard taken on the line 03-00 of Fig. 3. Fig. 3 is a broken plan view of the jacquard; Fig. 3 an enlarged view of, one part of the Jacquard machine; Fig. 4: aface view of a portion of the peg wheel"; Fig. 5 a side view of the same in section on the line y-y of Fig. 4. Fig. 6 is an elevation showing the construction and mode of operation of the star wheel used in actuating the shaft which feeds the cards. Fig. 7

is a side elevation of a device used in trans-.

mitting motion from the loom proper to the jacquard; Fig. 8 a plan view of the same partly in section on the line z-z of Fig. 7; Figs. 9, 10 and 11, detached views showing various portions of the said apparatus, and Fig. 12, a plan view, showing the shafts and gearing connecting the same.

A, indicates the loom proper, and B a rotating shaft thereof, said shaft as shown, being the driving shaft of the loom, and provided with fast and loose pulleys B and B and having at its end a sprocket wheel B which is connected to a sprocket wheel D on a shaft D by means of a chain 0. The shaft D, (see Figs. 1, 7 and 8) is supported in a bracket E and has attached to its end a miter wheel D which is engaged with miter wheels F, F journaled on a shaft F which said shaft is journaled in boxes E E secured to arms F. E of the bracket E. The shaft F is in turn connected with a shaft N secured to the reciprocating frame 0 of the Jacquard apparatus; while this connection can be made by any convenient device for communicating motion I have shown a particular device indicated in Figs. 1 and 12; a miter wheelfbeing secured to the end of the shaft F and engaged with a miter wheelf, on the end of a shaft M journaled in a bracket secured to the frame of the loom A and connected by a universal joint m with a shaft M supported in brackets as shown in Fig. 1 and connected by a second universal joint m with a shaft M which has a miter wheel m atits end engaged with a miter wheel n on the shaft N.

Returning now to the particular construction of the mechanism; F Figs. 8 and 12, indicates a clutch member turning with the shaft F butfree to move along it, which can be made to engage either of the miter wheels F with the shaft and as the said miter wheels are driven in opposite directions by the wheel D the shaft F is driven forward or backward at will by shifting the position of the clutch. The use of such mechanism for reversing the action of a driving shaft connected with the jacquard is shown and described in the Zimermann application, but, by means of devices which Iam about to describe, I have adapted this mechanism to be automatically actuated from the jacquard itself. To an arm E rising from the top of the bracket- E, I secure a bearing E for apin or shaft E which extends out over the shaft F; upon this pin I journal a sleeve G having a downwardly extending arm G the branches G G ofwhich are engaged with the clutch member F so as to shift its position along the shaft F as the sleeve G is turned on its bearing. Preferably I form the sleeve G with arms G G extending upward and serving to supporta latch pin J having a head J and a collar J secured to the latch pin by any means as by a pin J against which collar rests a spring J which tends to push the latch pin forward. I also prefer to provide the sleeve G with projections G G4 the function of which is toserve as a stop for a device to be hereinafter described, and I secure to the sleeve a pin or stud G extending upward from the end of the sleeve and upon which pin is journaled a sleeve H; a spring G being preferably employed to press upon said sleeve and prevent it from moving too readily upon its bearing. From each side of the sleeve H extend arms H H which as shown are provided with heads H 11 and from the face of the sleeve I extend a series of ratchet teeth H H H in the path of the latch head J. Some convenient mode of attaching cords to the arms H is also to be provided, for instance, the eyes H H K is a slide to which a reciprocating motion is given by means of a cam D secured to the shaft D. As shown, this slide or plate K is formed with heads K and K which pass over a tubular extension 6 of the bracket E and the shaft or pin E respectively.

K indicates a cam roller secured to the plate or slide K and lying in the path of the cam D At the upper end of the slide K are formed outwardly extending arms K K.

I I indicate cords which are connected as through bell crank levers it" and cords i (see Fig. 1). with appropriate hooks of the Jacqu ard apparatus.

The operation of the mechanism above described is as follows: Assuming the clutch member F to be in the position indicated in Fig. 8 and the pattern calling for a reversal in the action of the jacquard, the card I is pulled by the appropriate hook and acting upon the arm H of the sleeve H to which it is attached turns the sleeve on its pivot pin G the head H being thus drawn from above one of the arms K of the plate K and the head [I connected with the other arm moved to a position above the other arm K the latch pin J yielding to the pressure and being forced in so as to pass over the tooth H and to set itself between the said tooth and the tooth H The extent of the motion of the sleeve is limited and regulated by the stop G against which the arm H comes, stopping further motion in the sleeve at the proper time. Now, the plate K is constantly moving up and down and on its next upward movement'after this change in the position of the sleeve G it comes in contact with a head H and pushing upward on said head and acting through the arm H the sleeve H and the pin G upon the sleeve G it causes said sleeve to turn on its supporting stud and to move through its arm G G the clutch member F so as to leave its engagement with the lower wheel F and engage the upper wheel F (Fig. 8). in consequenceof which the motion of the shaft is reversed. It will be noticed (see Figs. 7 and 11) that I have provided a number of shallow pin holes g g g on the outside of one of the arms G These are engaged by a spring pressed latch pin L shown in Fig. 7 which serves to steady and hold the clutch member in position. Vt hen in engagement with the .pin holes P turn the shaft P through a certain deter pin hole g the latch pin holds the clutch member out of contact with both gear wheels, thereby stopping the motion of the jacquard, and when the clutch member is moving, the pin L, which has a rounded head as shown, is readily forced back out of one hole and when the clutch is sufficiently moved falls into the next. The desired motion of the sleeve G and the engagement of the latch pin L with any one of the holes g 9'9 can of course be accomplished by suitable connections with the jacquard.

Referring now to the Jacquard apparatus proper, T indicates a stationary frame used to support the needles and hooks in the usual way; 0, is a reciprocating frame, which as shown is connected with bars 0 O which slide in brackets T T on the frame T and to the ends of which is secured a needle dressing plate 0", the bars 0 being preferably adjustably secured in brackets O on the frame 0 by means of screws as shown in Fig. 3. On the frame 0 is journaled the shaft N, which is kept in constant rotation by the action of the driving mechanism previously described, and a shaft P which is given an intermittent rotation through the mechanism best shown in Fig. 6, that is to say, a star wheel P is secured to the shaft P and a corresponding wheel N to the shaft N, the wheel P having rests or recesses P interposed between pin holes P and the wheel N having a circular portion N which feeds into the recesses P and a pin Y which engages the The action of the pin N is to mined arc of revolution while the action of the circular portion N is to hold the shaft P stationary during the intermission between the actions of the pin upon the wheel P. This combination of the two shafts and their connecting mechanism is the same as that described in the Zimermann application. On the shaft P is supported mechanism for feeding the cards of the jacquard and I prefer to employ asdoes Zimermann in his machine, two peg wheels indicated at Q Q, said peg wheels being secured to the shaft P and adapted to engage the peg holes on the opposite sides of the cards; instead however, of using circular rims on my peg wheels as does Zimermann I construct the rims of polygonal form, each face being of substantially the breadth of a card and having a peg Q at or near its center, the flat faces being indicated by the letter Q. In this wayI provide a level bearing for the card and prevent it being strained and bent and also avoid undue strains on the lacing connecting the cards. Another improvement in the construction of the peg wheels is to form each wheel with its rim of substantially the same breadth as the peg. his is advantageous, first, because it prevents the lacing along the outer edge of the cards from hearing and rubbing against the peg wheel, and also because it enables me to carry the needle holes closer to the pegs;

still another mode consists in forming between the pegs a series of holes indicated at q, properly spaced to correspond with partial rows of holes in the cards, the needle passing through such holes in the cards and into the face of the peg wheel. Obviously, this construction enables me to use a peg wheel or wheels of any desired breadth as holes can be formed in its face at proper intervals, but I prefer to use the narrow peg wheels having holes q only between the pegs.

I prefer to use the device described in the Zimermann application for supporting the cards in front of the needles, that is to say, a card supporting plate R, supported as upon bars 0 firmly attached to and forming part of the frame 0 instead however, ofattachin g the plate R rigidly to the arms 0 I provide in the rear of the plate R, arms or brackets R which in turn are secured to the ends of the bars 0 by clamps as indicated at E By making the plate R adjustable by this or a similar device I gain an important advantage and am enabled to adjust the plate with great accuracy to correspond with the position of the needles. This adjustment is also facilitated by the device which consists in carrying the needle holes 1% r or at least a portion of them completely through the plate B, so that in adjusting the plate, the operator can look through said holes and see thepoints of the needles. For practical use, it will besufficient to carry, say, two end rows of holes through the plate.

As in the Zimermann machine, I employ a needle board S, which is free to move backward and forward under pressure. Instead however of effecting the backward motion of the needle board by the pressure of the card support transmitted through the card to the needle board I provide special appliances which, as the card supporting device ad-v vances, moves the needle board backin front of it; the arrangement being such, that the card support and needle board while they approach close together, will not actually pinch the card between them. In the plan shown, this result is accomplished by providing the needle board S with lugs S S extending over the rods 0 upon which the needle board is thus supported. From these lugs S, arms S in the construction shown, extend over the bearing T and at their rear ends are secured to sleeve S Against this sleeve S presses a spring S which abuts at its other end against the bearing T or any convenient stop. A collar 8, preferably adjustable, is secured to the bars 0 in front of the lugs S and it will be seen as the frame 0 and its connected bars 0 move toward the stationary frame T, the collars S will, at a determined time press against the lugs S carrying them and the needle board S along in front of the advancing card support and preventing the card from being squeezed bet ween thesetwo plates. As the frame 0 moves backward, the plate S will move with it until the sleeves S come in contact with the bearings T which arrest the motion, holding the plate S stationary, while the card support moves backward and opens the space into and from which the cards are,

fed.

In the use of the Zimermann apparatus, I have found that it is of great importance that the card should be engaged and disengaged by the pegs on the peg wheels with a smooth even motion, and I have ascertained that this can be secured by forming and arranging the stripper and feeder plates W and W v which may be conveniently formed, as shown in Figs. 2 and 6, of one piece of metal, so that they will lie nearly perpendicular to the pegs from and to which they lift or lead the cards. The angle formed at the operative point is very slight, as shown in the drawings, and a twisting of the card is thus avoided. In Fig. 2, these plates W, W are shown secured in proper position to the frame 0 of the jacquard which affords a convenient support.

It is important that the cards should be held on the face of the peg wheels between the feeding and stripping plates and particularly between the feeding plate and the card supportin front of the needles, and still more particularly is it necessary to press the card down without twisting it upon the peg to which the feed plate delivers it. I accordingly provide a guard plate W one end of which extends over and lies parallel to that portion of the feed plate W which delivers the, card to the peg wheel. This guard plate and the guard plate W which prevents the cards from leaving the peg wheel too soon, are secured in place as shown in the drawings; that,

is to say, arms 0 are secured to the frame 0 extending up and down therefrom, above and below the peg wheels and the ends of these Having now described my invention, what I claim as new, and desire to secureby Letters Patent, is- V 1.
