AUTOMATIC TAKE-UP FOR KNITTING-MACHINES.

SPECIFICATION forming partl of Letters Patent No. 433,251, dated. July 29, 1890.

Application filed June 15, 1889- Serial No. 314,453. (No model.)

To aZZ whom it may concern:

Be it known that I, HERMAN MEIER, a citizen of Switzerland, having resided in the United States one year last past, and declared my intention of becoming a citizen thereof, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Automatic Take-Ups for Knitting-Machines, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to an attachment for knitting-machines adapted automatically to draw the knitted fabric when com pletcd away from the needles.

The invention consists in the provision of vertically-reciprocating hooks or catches arranged in series alternately to rise and fall by automatic means of simple and effective construction and operation.

Figure 1 represents a partial elevation and section of the needle-cylinder and attachments of a knitting-machine embodying my improved construction. Fig. 2 represents a similar view with the parts in a different position. Fig. 3 represents a side elevation of a part of the cylinder and the operating mechanism. Fig. 4 represents a detail view of the latch in sectional elevation.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates the needle-cylinder, which may be of any wellknown form of construction, and is provided with a gang of needles arranged therein in the ordinary manner. An internal cylinder B is secured in the lower part of said needlecylinder and depends from the bottom thereof. The upper part of the latter cylinder is constructed with two flanges C, one arranged at the top and the other below to provide a recess. The said flanges have aligned apen tures 0 formed therein for the reception of the shanks D of metal hooks or catches D. Springs E surround the shanks of said hooks between the flanges C. These springs bear against the top flange at their upper ends, and are limited at their lower ends by pins 6, passing transversely through the shanks of the hooks. The said springs keep the shanks of the hooks normally depressed below the lower flange C, and are all held thereby at auniform distance below the said flange.

A ring F is mounted on the lower end of the inner cylinder B, and is held in connection therewith bya headed stud G. The ring is provided with a camway II, consisting of a gradual rise or incline running into a hori zontal wall, which terminates in a vertical wall or shoulder. The stud G is located in such manner as to form a stationary projection to coact with the camwayl-I. hen the horizontal wall of said camway rests on the stud, the ring F is down in its normal position and the lower edge thereof flush with the lower edge of the cylinder 13. An arm J is secured to the ringFat aright angle to the lower edge thereof and provided with a top vertical extension J, with an elongated slot therein, through which clamp-screws J 9 pass to provide an adjustable connection for the same. A lever K is pivoted to a part of the framework and projects upward to bear against the arm J. This lever is long enough to cause a continual engagement thereof with the said arm J, and limited in its backward movement by a stud It.

A cam M is mounted on the shaft L, and is adapted to engage the lever K and impel it in the direction of the arrow, as shown in Fig. A series of obliquely-arranged springs N are secured at their lower ends to the ring F and at their upper ends to the lower flange O of the cylinder B. These springs have attaching-blocks, which elevate the same and prevent contact thereof with the parts over which they extend. The stud G also forms the pivotal connection for a gravity-latch P, having a lower weighted end B, provided with a pin '2', moving in a slot 1) in the lower end of the cylinder B. The latch P is formed with the weighted end B to insure at all times a return of said latch to a vertial position, and the slot b and pin 0' are adapted to the movement of said latch. The upper end of this latch is bifurcated to form a vertical arm 19, provided with a top bevel m, and an oblique arm 1), the upper end of which is bent inward at an angle and forms abearing-surface for a purpose hereinafter set forth. Above the ring F a ring S is located, and is con- IOC engaged shanks rest stationary.

structed with a series of upwardly-projecting fingers S, arranged at equal, distances apart and of a regular length, and upon which rest a part of the depending ends of the shanks D. A line of studs 3 are arranged at the centers of the bases of the fingers and'at the centers, of the spaces between the same. These studs exactly correspond in number to the number of hooks employed.

The cam-arm M as it is revolved by the shaft L engages the lever K and forces it forward. The lever bearing against the arm J impels it and turns the ring F, which rises as the inclined wall of the camway thereof rides over the stud G. As the ring F rises, it also gradually elevates the ring S. One-half of the shanks D of the hooks D normally rest on the fingers S of said ring S, and the remaining shanks depend centrally over the spaces intersecting said fingers. In view of this arrangement, when the ring S rises, the fingers S thereof force the shanks of part of the hooks upward, while the remaining non- As the ring S rises, one of the studs 5 strikes under the bent end ofthe arm 19 of the latch P and tilts the latter back until the upper beveled end of the arm 1; lies in the vertical path of descent of the next adjacent stud 3. At this time the cam-arm M will have become disengaged from the lever K and the. ring F returned to its normal position by the springs N. The obliquity of the springs N causes the line of draft thereof to be at an angle to a horizontal plane, and when the ring F is revolved by the arm K it is moved against the resistance of the said springs, which will then be drawn laterally at a greater angle than when in their normal position, and at the moment when the ringF is released from the arm K the said springs return to their normal position and draw the said ring around therewith. It will be understood that the said springs will have.an inherent retractile tension of suificient power to overcome any resistance offered thereto by the ring, and that the said ring will move freely on the cylinder B. When the ring F revolves backward,

. it descends gradually through the medium of the camway H thereof riding over the stud G. The springs N have no function whatever in raising the ring F, the latter movement of the ring being accomplished through the camway H, the stud G,- arm J, and lever K, as stated, the said springs acting to resist a revolution of said ring F and bring the same into its normal position, as shown in Fig. 2. It is for this purpose that the said springs are arranged obliquely. Thelever K is thrown back against its stud k, and the ring S descends with the said. ring F until the upper ends of the fingers S are slightly below the lower ends of the depending shanks D of the hooks D'. As the ring S is lowered, the stud 8 above the beveled end of the arm 19 of the latch P rides downward over the said arm, thereby turning the ring S around to allow the fingers S to become disengaged from the ends of one set of shanks D and engage the next successive shanks.

The ring S is constructed with one-half the number of fingers as there are hooks D. By this means one half of the said hooks are raised to engage the knitted fabric, while the other half remain stationary until in like manner successively operated. The hooks are lowered by the retractile action of the springs E, and caused to contact either with the upper ends of the fingers S or to depend over the space between said fingers.

ed, as the said hooks will continuously clear the fabric from the needles.

The operation described is that employed In addition to the propelling function of in continuous circular knitting in the formation of the stocking-leg.

WVhen the heel is constructed, one-half of the needles are thrown out of operation by well-known means, and a part of the hooks are actuated alternately on one side and remain idle on the other. Then the needles are raised on one side of the machine, they form no stitches, and therefore do not increase the length of the fabric nor feed the same down. Consequently said portion of the machine is idle, and the hooks D, which have been operated to take hold of the fabric on the idle side of the machine, are held elevated by engaging the said fabric, and are thereby thrown out of action as their shanks D are raised above the fingers S of the ring S.
