Patented Sept. 19, 1950 NEEDLE DRIVING APPARATUS FOR SEVING MACHINES Victor M. Newman, New York, N. Y.
Application February 10, 1949, Serial No. 75,596
6 Claims.
This invention relates to a needle driving apparatus for sewing machines and more particularly to a structure for actuating an elongated needle in the sewing of a necktie.
It has been known to crimp or pleat fabrics over a substantially stationary block and thereafter drive an elongated needle through the crimped fabric so as to produce stitches therein. According to the present invention, an elongated needle is disposed around the periphery of a rotatable wheel which is enclosed in a stationary housing. When the wheel is rotated, the needle is guided by the inner wall of. the housing and is forcibly driven through an outlet in the housing. The structure is positioned adjacent' to the fabric crimping machine and the threaded needle is appropriately guided into the machine and driven alon the crimping means so as to produce stitches in the crimped fabric when the wheel is reversely rotated and the needle accordingly withdrawn. By providing an arcuate housing which directs the force of the actuated needle in the proper direction, a positive action is assured notwithstanding the fact that the needle may buckle in relation to the driving wheel. The housing is formed with an outlet nozzle which guides the free end of the needle with precision and accuracy so that it cannot buckle in the outlet end of the housing.
The invention will be further understood from the following description and drawings in which:
Fig, l is a side elevational view of the needle driving apparatus, partly broken away.
Fig. 2 is a section taken substantiall along the lines 2-2 of Fig. 1.
Fig. 3 is a fragmentary section taken along the lines 3--3 of Fig. 1.
Fig, 4 is a fragmentary view illustrating a modification wherein the annular flange of the housing is formed with a needle guiding groove.
The apparatus comprises an arcuate stationary housing it which may have an open side, if desired, in order to provide access to the wheel I! as illustrated in Fig. 2. However, it is evident that the wheel ll may be partially enclosed at its periphery by extending the housing thereover. As illustrated, housing it! is formed with an integral annular flange which embraces the periphery of wheel H. The hub l2 of wheel H is connected to shaft lt which is rotatable in the housing so as to rotate the wheel H accordingly. Both manual or mechanical driving means may be provided. For the first expedient, a handhold member it is connected near the periphery of the wheel so that actuation thereof 2 will rotate the wheel within the housing. Shaft I3 is enlarged at its other end and rotatably maintained within hub iii of the arcuate housing. A pulley It may serve to apply mechanical driving power to the shaft it in lieu of manual actuation of handhold member l4.
The periphery of wall H is formed with a groove ll in order to receive the flexible elongated needle 13. Needle 18 has one end l9 thereof connected as by bolt 29 to a peripheral point on wheel H which is adjacent handhold memher it. The needle 58 which is, of course, resiliently flexible thereafter extends arcuately within the groove H and along the floor H of the housin as the needle emerges from the housing. A nozzle 222 communicates with the opening above floor 2! so that the needleis guided outwardly in tangential relationship to the wheel and housing. Accordingly, from the position illustrated in Fig. l, the handhold member l4 may be actuated in a counterclockwise direction whereupon the needle will be driven outwardly so as to eilect its sewing function. In order to limit reverse movement thereof, a pin 23 is formed on the wheel l l while a stop bar 24 is formed on the housing It. When the pin 23 meets the stop bar 24%, further inward movement of "the needle is prevented. A spool of thread 25 is supported on ledge 26 of the housing Ill and the thread 2i is inserted into the eye of the needle is as will be understood.
When the apparatus is to be used, the needle is appropriately threaded and the handhold member l4 actuated in order to drive the needle as required. The spacing between the periphery of the wheel H and the inner peripheral wall of the annular flange of housing I0 is small and may be slightly less than the width of the diameter of the needle. Accordingly, the needle Hi can buckle very little as it is actuated, but such buckling is of no adverse consequence in that the inner peripheral wall of the annular flange of the housing acts as a guide for directing the force of the actuated needle in the proper course. If desired, such inner peripheral wall may be formed with a groove 30 opposed to groove ll so as to receive the needle as it departs radially outwardly from groove I! and so as to thus enhance the guiding function of the inner peripheral wall. Groove 30, as shown in Fig. 4, will guide the needle accurately as it departs from groove H. The nozzle 22 may fit the needle diameter closely so that it is substantially gestrained from wavering as it emerges there- .rom.
The inner peripheral wall of the housing may be of polished metal in order to offer minimum friction to movement of the needle when the wheel is actuated. After the needle has been reciprocated through the entire crimped length of the fabric, and the thread retained as will be understood by those skilled in the art, the handhold member I4 is reversely rotated to return the needle into the housing M in preparation for a succeeding operation.
The aforesaid structure provides an elongated needle actuating device which is of utmost simplicity although effective for its intended purpose. Changes and modifications may readily suggest themselves and it is therefore desired to define the scope of the invention by the claims hereto annexed.
What is claimed is:
1. An elongated needle actuating apparatus comprising a rotatable wheel, means to rotate said wheel to project or retract the needle, an elongated, resiliently flexible needle having one end connected to a peripheral point on said Wheel and extending in one turn along the periphery of said wheel when the wheel is in needle retracted position, and an enclosing stationary guide wall adjacent the periphery of the Wheel for limiting radially outward movement of said needle, said guide wall being polished so as to offer minimum friction toward travel of said needle as it bears thereagainst during actuation of said wheel.
2. Apparatus according to claim 1 and wherein the spacing between the periphery of said wheel and said guide wall is less than the diameter of said needle.
3.

5. A needle actuating apparatus comprising an arcuate, stationary housing, an annular flange on said housing, a wheel rotatably supported in said housing and having its periphery embraced by said flange, means to rotate said wheel, an elongated, resiliently flexible needle having one end thereof connected to said wheel and extending in one turn along the periphery thereof when the wheel is in needle retracted position, and an elongated nozzle formed on said housing and extending tangentially thereof, the other end of said needle being receivable through said nozzle so as to reciprocate the needle tangentially of said wheel as the wheel is rotated.
6. An elongated needle actuating apparatus comprising a rotatable wheel, means to rotate said Wheel to project or retract the needle, an elongated resiliently flexible needle having one end connected to a peripheral point on said wheel and extending along the periphery of said wheel when the wheel is in needle retracted position, and an enclosing, stationary, annular guide wall disposed around and adjacent the periphery of the wheel for limiting radially outward movement of said needle, the radius of said annular guide wall being greater than the radius of said Wheel to an extent less than the diameter of said needle, and a groove formed in the periphery of said wheel for longitudinally seating said needle.
