LOUIS MORINSKY, OF NEW YORK, AND EDWARD K. MADAN, OF BROOKLYN, NEW YORK, ASSIGNORS 'IO LOUIS V. ARONSON, OF NEWARK, NEW JERSEY.

TOY KNITTING-MACHINE.

Application filed January 16, 1919.

To all whom it may concern:

Be it known that we, LOUIS MORINSKY and EDWARD K. MADAN, citizens of Russia and United States of America, respectively, and residing at, LOUIS MORINSKY, 832 VVhitlock Ave., New York, N. Y., and EDWARD K. MADAN, 260 Milford St, Brooklyn, N. Y., have invented new and useful Improvements in Toy Knitting-Machines, of which the following is a specification.

This invention relates to toys, more particularly to a toy adapted to knit a chain of thread which may be employed in any manner the user of the toy sees fit.

The invention has as its object a toy of a new and useful character and design, which may be economically manufactured and cheaply sold, which will, by reason of its novel character and construction, furnish amusement and at the same time produce an article which may itself be used by children in their play.

We are aware that knitting machines as commercial devices adapted to produce arti cles of clothing are old. To such a machine we lay no claim.

The machine shown in the accompanying drawing will knit only a chain of thread and is adapted for use only as a toy. It is cheaply constructed and sells at an inconsiderable price, rendering the same particularly adaptable for play and amusement.

Broadly, the toy consists of an inner stationary cone having a plurality of needles thereon, an outer revoluble cone provided with a cam groove in which ride projections upon the shanks of the needles. Revolution of the outer cone produces a vertical reciprocation of the needles and the knitting of a chain of thread supplied from a bobbin on an adjacent spindle.

Other features and objects of my invention will be disclosed in the following description, claims and accompanying drawings, in which:

Figure 1 is an elevation of the device.

Fig. 2, a vertical cross section of the outer cone sleeve on the line 22 of Fig. 1.

Fig. 3, a vertical cross section of the main body of the device as shown in Fig. 1, the section being taken in a plane at right angles to that of Fig. 2, and

Fig. 1, a horizontal cross section on line H of Fig. 1.

Referring more particularly to the sev- Specification of Letters Patent.

Serial No. 271,380.

eral views, at 1 is indicated a revoluble frusto-conical sleeve on an inner stationary frusto-cone 2 provided at its base with a laterally extending arm 3 by means of which the device may be clamped to a table or other suitable support. Extending horizontally from the sleeve 1 is a spindle support 4 upon which is located the bobbin spindle 5 and a thread guide holder 6 adjustably receiving by means of a set-screw the usual thread guiding tube 7.

As distinctly indicated in Fig. 2, the revoluble sleeve 1 is provided upon a portion of its interior with a lining 8 having a cam groove 9 adapted to receive projections 10 (Fig. 3) upon the shanks of needles 11 located in vertical grooves 12 upon the inner stationary frusto-cone 2. The cam groove extends entirely around the inner circumference of the sleeve 1, it having a straight course in a horizontal plane, except at the point of the downward dip or curve shown in Fig. 2, and its edge is ratcheted at 13 for the purpose of preventing reverse rotation of the sleeve 1. The manner in which the ratchet teeth operate to attain this end will become apparent as the description proceeds.

The needles employed are the usual pivoted-latch type knitting needle, each having the customary latch 11 and hooked tip 11 While in the specific embodiment of our invention disclosed in the drawings four needles are used, it is obvious that the number might well be increased or decreased, as desired. lVe have found, however, that four needles give the most satisfactory results.

In order to prevent vertical play of the cam sleeve 1 upon the inner stationary member 2, a screw 11 is passed through the sleeve adjacent its lower edge, the screw riding in a circumferential groove upon the stationary cone 2 when the outer cone-sleeve is rotated.

After placing the bobbin B upon the spindle 5 and leading the thread through the guide 7, the cam sleeve 1 with its thread guide and bobbin is revolved in a clockwise manner about the stationary frusto-conical member 2 and the needles 11. Reverse or anti-clockwise revolution of the cam-sleeve is prevented by the ratchet teeth 13, which upon such rotation would immediately strike against the shank projections upon the needles. This rotation may be effected by grasping the bobbin spindle 5. As revolution of the cam sleeve progresses the thread is engaged successively by the hooks 11 upon the needles as the latter vertically reciprocate, due to their shank projections 10 in the cam groove 9. Each needle takes a downward and upward movement once in each revolution of the sleeve. When the needle is in its elevated position the latch 11 is open, but upon the descent of the needle the hook engages the thread being supplied from the bobbin, and the latch upon still farther descent of the needle, by reason of its tip striking the upper edge of the cam sleeve, swings upward against the hook. Continued descent of the needle pulls the thread through the previously formed loop of the chain, thus adding another loop to the latter. The needle then ascends, the latch opening and the needle passing through the newly formed loop. Each of the four needles passes through the operations mentioned above, once in each revolution of the cam sleeve. It is thought that the operation of such devices as this is so well known to those skilled in the art of knitting that further description is unnecessary.

While we have shown and described in detail a specific embodiment of our invention, it is, of course, understood that such modifications may be made therein as come within the scope of the following claims.

What we claim is:

1. In a toy of the knitting machine type, the combination with a stationary member, and needles carried thereby, of a revoluble needle actuating member, and means on said revoluble member and cooperating with said needles for preventing reverse rotation of said revoluble member.

2. In a toy of the knitting machine type, the combination with a stationary member and needles mounted for reciprocation thereon, of a revoluble member mounted upon said stationary member, and means arried by said revoluble member for reciprocating said needles and so formed as to prevent reverse rotation of said revoluble member.

3. In a toy of the knitting machine type, the combination with a stationary needle carrying member, of a revoluble member carrying a needleactuating cam of such profile as to prevent reverse rotation of said revoluble member.

a. In a toy of the knitting machine type, the combination with a stationary needlecarrying member and a revoluble member, of a am member carried by said revoluble member and provided with a needle-actuating cam groove of such profile as to prevent reverse rotation of said revoluble member.

In a toy of the knitting machine type, the combination with a stationary member, of reciprocatory needles mounted thereon, and a revoluble member having a needle actuatin cam groove provided with teeth which by cooperation with said needles serve to prevent reverse rotation of said revoluble member.

6. In a toy of the knitting machine type, the combination with a stationary member carrying needles and a movable needle-actuating member, of a cooperating means on said movable member and said needles for preventing reverse rotation of said movable member.

In testimony whereof we have signed our names to this specification this 15 day of January, 1919.

LOUIS MORINSKY. EDWVARD K. MADAN.
