To all whom it may cmwern:

1 Be it known that I, CHARLES YOUNG, ofthe city of Chicago, in the county of Cook and State of Illinois, have invented certain new 5 and useful Improvements in Looped Fabrics andCrocheting-MachinesforMakingtheSame, of which the following is a full description, reference being had to'the accompanying drawings, in which' I a rq Figure 1 is afront elevation ofmy improved machine; Fig. 2,avertical cross-se'ction on line re m, Fig. 1 Figs. 3 and 4, end elevations; Fig. 5, a de '1 view of the cam for operating the yarn-ca rying arms; Figs. 6, 7,8, 9, 10, and 11, views showing the difl'erent positions of the yarn. while making the fiibric; and Figs. 12 and 13, elevations of the needle, showing thelatch opened and closed.

This invention relates to improvements in the class of machines especially adapted for making loop-stitched fabrics, whereby I am;

'30 from a single series of threads and knot the loops firmly into the body of the fabric, wherebjv they are ihcapableot' beingdrawn orrareed out, and thus forming anew article of manufacture, all as hereinafter more fully set 5 forth. .7 1

The frame or standard cast-iron or other suitable material, and of any A may be made of 'I desired form or shape to receive and furnish a support for the operating devices, the size .of the'stnndards and their distance apart dependingon'the size of the1nachine. Each standard, as shown at its lower end,-1s provided with an opening, Q, by means of which and a set-screw, Q, the device can be secured to a table or bench, the edge of the table or .bench entering the slots or openings Q. The.

upper portions, A, of tlrese standards are not as thick as the lower lidrtions, and are-rounded ofl at theirjtbps, and to'them aresecuredarms or supports A", which extend back some distance fron'i't'he standards, as shown in Fig. 2 The shaft B has its bearings in the tower ends of'the standards A, and one end projects somedistance beyondlthe standard, and to it or disk, I, rigidly secured to the shaft, so as" to revolve therewith in any suitable manner,

which wheel is provided with two projections,

p p, located a little distance apart on the edge or periphery of the wheel or disk, the metal of the cam, disk,.or. wheel between the projections being cut away, as shown in Fig. 3, so as to leave a lower surface than the balance of the periphery of the cam wheel or disk.

On the end of the shaft G" that supports the gear-wheel G is located another cam wheel or disk, M, also rigidly secured to the shaft, so as to revolve therewith, the outer face of which is provided with a flange extending around the circumference of the disk, which flange is provided with a series of projections and depressions or notches, in kl l m m n, the depressionsextending to the same depth and the projections varying .in height, k beinghigher than the others.

Between the standards Aon the shat'tB are rigidly secured two eccentrics, located at the proper distance apart and revolving with the shaft, each eccentric being provided with its ring or strap 0 and connecting-rod C",whieh may. be of any of the well-knownforms of construction suitable for the purpose of operating the needles.

The upper ends of the connecting-rods U are pivoted, as.shown, to cars D, secured to or formed with the bar D, which moves in suitable guideways, D, secured to the standards, which cars, at their upper ends, are pro; vided with slots a, by means of which and suitable set-screws,b, the bar D (which is located above the bar D and between the inner faces of the gnideways or standards) can be connected with the bar D, so as to move therewith, the object of the slots a and set-screws being to so adjust the bar D as to leave the required space, 0, for the reception of the heels d of the needles, which needles consist of a shank, e, a'hook, e, and a retaining and discharging latch, e, as shown in Figs. 12 and 13, and may be of t-he required length and construction suitable for holding and releasing the stitch formed thereon, as hereinafter specified. The shanks e of these needles rest upon a backorsnpporting plate, E, located beneath the bars I) 1), and are secured in any suitable manner to the standards A.

The number of needles will depend upon the size of the machine and width of the fabric which it is desired to form.

The upper end of the plate E is provided.

with a series of'prqjections, f, having inclined points projecting a little distance above the upper face of the plate E, between which projections f are grooves or openings, which form gnideways or passages for the'needles, which are moved up and down by the action of the eccentrics 0.

On the shaft B, next tothe inner face of each standard A, is located'a gear-wheel, F, rigidly secured to the shaft and revolving therewith, which wheels F engage with gearwheels G, having their bearings on the standards above and to one side of the shaft, and to which'are secured the ends of the bars G, the attachment being made at one side of the centers of the wheels, so as to give the rods the" proper eccentric movements, the other ends of the bars being secured in any suitable 'manner to the bar H, which moves in suitable guidewa ys, H, suitably secured to the stamiards A, and supports the-loop-pins h, which may be of any desired length, located in the bar at the required distance apart for the passage of the yarn-arms when forming the loop.

Between the plate E and the bar H is a plate, H, secured to the standards, and so located as to leave aspaee between it and the plate E for. the passage of the fabric when formed.

The arm or lever J is pivoted at q to a support or bracket, J, secured to the side of the standard, and is so arranged that its lower end will engage with the projections pp and come in contact with the face of the wheel J after it has'passed p, the support J being provided with a slot, '0, to enable the proper adjustment for this purpose to be had. The other end of this lever or arm J .is pivoted at r to a connecting-rod, which, as shown, consists of two sections, K K, united by means of the ear or projection s on the part K and the set-nuts s projecting beyond the upper portion, A, of

the standards in which they have their bearings. To this flat bar or plate L are rigidly secured arms or supports g, the outer ends of which are provided with holes, which arms are arranged at a little distance apart, their loca- 1 tion being such as to allow the arms to pass between the needles properly.

The arm or lever N is pivoted at t between the ears of support N, secured to the standard A at the opposite end of themachine, the ears or support having a slot, u, by means of which the arm or lever N can be adjusted to engage properly with the wheel M and the end of rod or'spindle L.

The lower end of the arm on lever N is pro- ,vided with an anti-friction roller, 0, which enygages with the projections and depressions on the flange of the cam-wheel M, and the upper end comes in contact with the projecting end of the spindle L,'whieh is kept in contact with the arm or lever by the action of the spring R, or in some other suitable manner, oneend of which is secured to the bar L and the other to the standard A, so that the force or stop, N", so located as to keep the lever in position.

On the, projecting end of L' iis arranged a stop, 0, which engages with the end A of the. standard, and prevents the bar L from being depressed except at the proper time.

Above the bar L,and supported by the arms A", adj ustably secured to the standards by the slots t and set-screws or bolts, is tired or bar,

P, in which .is arranged a series of pins, j, at the proper distance apart; j

The spring It is located back of the bar L and parallel therewith. The vertical spring 8 is secured at its upper end to the lower corner of the bar L, and at its other end to that portion of the standard which is provided with the slot Q. I

Other forms of springs than the .coil-sprin gs R B may be used, their arrangement-being such as to keep the bar L so as to be operated by the lever or. arm Nand to be depressed at the proper time. V

- The arrangement and location apart of the arms 9, loop-pins h, and guide-pins j must'correspond with, or nearly with, the location apart of the needles, so as to bring them in the proper position to enable the arms 9 to give the peeessaryright-and-left and np-and-down movements'to the yarn or other material to form the stitches and loops. t

Other devices than those shown for actuating the arms 9' and other parts may he employed, their construction and arrangements being such as to give the required movements to the parts;

The location and arrangements of the act- I uating devices for the yarn-arms, needles, and

loop-holding pins and the movements of these several parts relativeto each other will be unders'tood from a description of the operation, which isas follows:

The yarn or material, T, from which the fabric is to be made passes from suitably-located bobbins over the bar P, between the guide-pins over the bar L, down by the sides of the arms '9, through the openings in the end'so'f the arms or fingers g, as many strands of yarn or other material being employed as requiredjfor the wid th of the fabric. The ehds of each strand, after passing th rongh'the openings in the arms or fingers g, are passed through the opening or space between the plates E and H. The parts are then to be brought to a position where the rollero will be acted upon by the incline k. and the end of the arm or lever J will be engaged by the projection p on the wheel I, whenthe machine is ready for operation. As the crank B is turned the shaft B will be revolved, which also revolves the devices thereto attached, causing the projectionp on the wheel or disk 1 to depress the lower end of the arm or lever J, which,through the needles, and with them the yarn; The roller 0 connecting-rod K K and crank K", raises the front edge'of the bar I), and with it the armsg; carrying the arms between and above the 7c on the arm or lever-N then comes in contact with and rides up the incline k, carrying the lower end of the arm or leverN to the left and the upper end to the right, which end giv'esa corresponding moveme'nt'to'the bar L and the arms 9 thereon, the extent of the movement being sufficient to carry the arms 9 to the right over two needles, and with them the yarn, the needles at. this time having been raised-by the action vof the eccentrics .0, and the loop-pins having been carried downby the action ofthe wheels G and rods G, so that the yarn will be carried overptwo needles, as shown in Fig. 6, then between and back thereof as the end of the leverJ leaves the projection 11, the arms gbeing prevented from being can ried too far back or down by the stop 0], which comesin contact with the upper end of A as.

the arm J leaves 1), and is between the two projections 2 p on the cam wheel or disk I, and not in contact with the face of the disk alt-that point by reason of its being cut away, as before described. The end of the arm or lever J then'comes in contact with the projection p on the cam-wheel or disk I, again raising the bar L and the arms 9 thereon, in the same manner as 1), between and above the needies, said arms being again returned between the same needles. As the arm leaves the pro;- jection p the roller 0 leaves the projection k, on which it has been traveling, and comes in contact with the projection l,j-thro wing the upper end of the arm on lever N to the left the same distance that it was carried to the right byth'e' incline k, the bar L, and with it the fingers or arms 9, with the yarnheld there:

by, being also thrown to the left by'the action of the spring R, carrying the yarn to the left beneath the needles the same distance that it was carried to the right, as shown in Fig 7.

has been traveling on the face of l, leaves it,

thus carrying the upper end of the arm or leverN to the left, allowing the spring R to throw the bar L, and with it the arms 9 and yarn carried thereby, to the left, which operation takes place while the arms 9 are'elevated. The distance traveled by the arms inthis movement must be sufficient to carry the yarn over-a single needle, as shown in Fig. 8. The end of the arm or lever J then leaves the projection p and comes between the two projections p p,- but as the arm is not in contact with the face of the cam-disk at this point V and the stop does not engage with the end 7 of A, the action of the spring 8 will throw the arms g back of the pins h on thcvbar H, which have been raised by the action of the wheels'G and rods G, the needles also having been raised by the eccentrics. The roller 0 then rides up the inclined face of the projection m on the cam-wheel M. carrying the upper e d of the bar or lever N to the right, and with it the bar L and arms 9 thereon, and the yarn 'carried by the arms, a sulficient distance to carry the yarn around the pin next to each arm 9 at the right, as'shown in Fig. 9. Then the end of the arm or leverJ again comes in contact with the projection n, raising the arms 9, as before described. While these arms are raised the roller 0 leaves the face of the projection m, on which it has been traveling, and enters the notch or depression m, whichthrows the upper end of the bar or lever N to the left and allows the spring R to act to carrythe bar L, and with it thearmsgand yarn carried thereby, to the left a distance sufficient to carry the yarn over a single needle, as shown in Fig. 10. The end of leverJ then leaves the projection 1') and comes in contact with the face of the cam-disk I, throwing the arms 9 back between the pins h and the needles, which are both. raised at this time by the action of their actuating devices, where they are held by the contact of the end of the lever J with the disk until the end of lever J again comes in contact with the projection 12. The needles are withdrawn right after the arm leaves p by the eccentrics, and as the hooks enter the spaces between the projections f on the plate E'the roller 0 will' ride up the endof the projection n, carrying the upper end of the arm N to the right and with it the bar L, arms gthereon, and yarn carriedrby the arms. The distance traversed is sufficient to carry the arms 9, which are below the needles, to the right far enough to carry the yarn under one needle, which completes the operation of a.

single loop and its holdingstitch. as shown in Fig. 11. The arm J then comes in contact with the projection p again, and the roller 0 rides up the incline k, andthe operations before described are repeated, and such movements are continued until the fabric is completed,-the action of the stitches, as the neodles are raised and lowered, opening and closing the latches,so as to catch the yarn on the hooks and allow the completed stitch to be discharged at the proper time. The yarn is carried by the arms up and to the right over two needles, then to the left under two needles, then the space over another needle to the left, then back of and around the loop-pins, then up and to the left over a single needle,

and then to the right under a single needle at each complete operation; and any other-form of actuating devices than those shown and described which will give such movements to the yarn may be used in connection with other devices for giving the movements described to the needles and loop-holding pins or devices at the proper time; or the devices might be so arranged as to carry the yarn over two needles to the left, and the other movements reversed accordingly.

What I claim as new, and desire to secure by Letters Patent, is-

- 1. As a new article of manufacture, a loopstitched fabric formed of a single course of threads without warp, and havingits loopsincapable of being drawn or raveled out, substantially as described.
