June 14, 1932. G. A. CARLSON LOOP FORMING. NEEDLE Filed Ocb. 3, 1930 @www " or catch, 4a.
Fatentecl June 14, 1932 UNITED STATES PATENT; 'oirica GUSTAV A. CARLSON, 0F CHICAGO, ILLINOIS, ASSIG-NOR T0 THE BOYE NEEDLE COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS LOOF-FORMING NEEDLE Application led yOctober 3, 1930. Serial No. 486,251.
This invention relates particularly to a needle adapted to the purpose of making rugs, or similar articles, where it is desirable to pass yarn through a foundation fabric,
such as burlap, and form loops at one side of the fabric, thus providing a nap, The loops may afterwards be cut to permit the yarn to spread and form a fuzzy nap.
An important object of the invention is to 1 provide for smooth, easy feed of the yarn, to-
gether with proper gripping' of the yarn between the needle and the fabric to enable the loop to be formed; and a further object is to provide for easy, quick application of the needle to the handle or removal therefrom.
The invention is illustrated in a preferred embodiment in the accompanying drawing, in which- Fig. l is a plan view of a device embodying the invention; Fig. 2, a broken sectional view taken as indicated at line 2 of Fig. l; Fig. 2a, a. section taken as indicated at line 2a of Fig. 2; Fig. 3, a view of a spring-catch which is connected with a. socket with which l the handle is provided; and Fig. 4L, a broken spring-catch.
The handle A is shown provided at one end with a reduced portion equipped with a ferrule l. This portion of the handle is provided with a` bore 2 within which is fitted a sleeve 3 having a projecting end-portion which affords a metallic socket, as indicated at 3a.
The sleeve 3 has secured to its inner end a leaf-spring 4 which is equipped with a stud, This stud normally projects through a perforation 3b with which the socket 3 is provided.
The preferred manner of attaching the spring 4f to the sleeve 3 is to provide the inner 51" end of the sleeve with a small slot 3c, the adjacent portion of the metal being struck inwardly at this point; and to bend the baseportion of the spring 4L back upon itself and spring it into engagement with the metal at the slot mentioned.
The needle B comprises a shank-portion 5 and a needle-portion 5a which terminates in a pointed tip 5b. y
Preferably, the needle-portion 5a is of concavo-convex cross-section, the needle being thus provided at one side with a longitudinal passage 5C through which the yarn may eX- tend longitudinally of the needle. rlfhe top, or back of the needle aiords a wall through which extend elongated perforations, or eyes, 6 and 7, which are located, respectively, near the point and base of the needle. The top Wall, or back wall, of the needle, has the metal struck inwardly at points 6a and 7a, adjacent the eyes G and 7 and between said eyes, thus forming grooves.
The shank 5 of the needle is of substantially tubular form and is of proper size to fit snugly within the metal socket 3a. rIhe shank is provided with a perforation 8 which is engaged by the spring-catch 4a when the parts are in the position shown in Fig. 2.
It will be noted that the stud-like catch la has a rounded outer end, which gives the ef- Thus, when the stud 4a* 1s ""f drawn. Also, the needle will be inserted by depressing the catch Ll and forcing 'the needle-shank into the socket, in which action one wall of the shank passes between the leafspring and the adjacent wall of the socket, it being noted that the shank will automatically force the catch inwardly out of the way, after the catch has been partially pressed by means of the finger. After the shank is properly entered in the socket, the catch snaps into position through the perforation 8, thus locking' the needle in position.
In the modification shown in Fig. 4, A designates a handle, and B designates a needle. In this modification, the shank-portion of the needle is equipped with a spring catch and the socket with which the handle is equipped is provided simply with a perfoi-ation adapted to be engaged by the catch carried by the shank-portion of the needle.
Describing the modification, the handle is provided at one end with a bore fitted with a sleeve 9 which has a projecting portion provided with a perforation 9a.
The needle B is provided with a tubular shank-portion 10 within which is 'securely mounted a leaf-spring ll equipped with a rounded catch 12 which normally extends through a perforation l0a in the needle shank and through the perforation 9 of the socket. The insertion and removal of the needle 'will be understood without description herewith.
A needle of the kind described may be formed of sheet-metal rolled into tubular form and having the lower wall cut away as indicated at 13 (Fig. 2), whereby the longitudinal passage 5C is open at one side.
The needle is threaded with yarn in a manner well understood in the art, and the usual method of operating is employed. When the needle is inserted through the foundation fabric, a loop of the yarn is carried through the fabric. In this operation, the yarn is pressed between the back wall of the needle and the adjacent portion of the fabric, so that the yarn is drawn taut on the back or reverse side of the fabric. In withdrawing the needle, the yarn is gripped between the back wall of the needle and the adjacent portion of the fabric, so that the yarn is held or partially held and caused to form a loop as the needle is withdrawn. It will be understood by those skilled in the art that the groove 6 particularly facilitates the feed of the yarn during the operation of inserting the needle through the fabric. In-a measure, the groove 7 facilitates the feed, particularly when the yarn which is being drawn through the eye 7 happens to be in position so that the yarn passes more or less `longitudinally through the base of the needle at the back side of the needle and thus is compelled to make a turn as it passes within the channel 5c of the needle.
As will be understood from Fig. l, the eyes 6 and 7 pass through depressed portions of the metal. The portions of the metal which are not depressed, serve to provide gripping surfaces for the yarn.
The improved device is simple, can be manufactured at moderate cost, and permits ready substitution of needles, when desired.
The foregoing detailed description has been given for clearness of understanding only and no unnecessary limitations should be understood therefrom, but the appended claims should be construed as broadly as 'permissible, 'in view of the prior art.
vWhat I regard as new, and desire to secure by Letters Patent, is:
l. A tube-like needle for'the purpose set having a forwardly presented end equipped with a locking-stud, a wall of said shank being interposed between said spring and the adjacent wall of said socket-member and having a perforation registering with said first- Inentioned perforation, said perforations being engaged by said stud.
3. In a device of the character set forth: a handle equipped with a shank-socket; a needle equipped with a tubular shank fitted in said socket, said shank and socket being provided with registering perforations; and a spring catch carried by one of said parts comprising a leaf spring extending longitudinally within said tubular shank and equipped at its forwardextremity with a rounded lock- 92 stud which projects through saidperforations and is adapted to be depressed by the 'finger to enable a release to be effected.
