THREAD-GROOVE CUTTER FOR SEWIhTG IIACHINES.
Specification of Letters latent. Patented Nov, 28, 1911.
Application filed February 20, 1911. Serial No. 609,698.
'art to which itappertains to make and use the same, reference being had to the accom panying drawings, forming part of this specification, in which- Figure 1 .is an elevation of a portion of a sewing machine showing a needle bar provided with a needle and grooving-tool; Fig. 2 is an elevation of the needle-bar, needle, and grooving-tool; Fig. 3 is a vertical section of the grooving-tool; Fig. 4 is a vertical section of the clamping-nut; Fig. 5
is a vertical section of the upper part of the.
needle-bar; and Fig. 6 is an elevation of the grooving-tool as seen from right to left in Fig. 2.
This invention relates to an improved grooving-tool, designed to be "secured to the needle-bar of a leather sewing machine, the object being to construct the parts in such manner that the grooving tool may be adjustably mounted in position and clamped in such adjusted position by the usual clamping nut employed for holding the nee dlc in place.
In the drawings, 1 indicates the needlebar, which slides in a recess 2 in the frame 3 of the machine, said needle-bar carrying a hooked needle 4 and a grooving-tool 5 at its upper end. The grooving tool is of the form shown, and is intended to operate in the manner described in the patentto Wheeler, No. 'gi46,398. 'lhe needle-bar is provided with a reduced extremity and asocket 6, in which the shank of the needle is held by jaws 7, formed by tapering and splitting the end of the needle-bar.
The clamping nut 10 has a threaded lower ortion to engage the reduced threaded portion of the needle bar, and also a tapered portion 1,0, which engages the tapered jaws 7 to (damp them upon the needle and hold the needle in position. The clamping nut 10 is provided with a non-circular portion 9, by which it may be turned on the upper extremity. "lhis clamping nut is reduced, as shown at 8, such reduced portion 'forced apart.
tool, being arranged upon the cylindrical being split and preferably made circular, so as to provide clamping jaws for the groovingiool socket. The socket of the grooving-tool 5 is made circular and fits upon the reduced portion 8 of the clamping nut,=being free to be rotated and moved longitudinally when the clamping nut is loose. W'hemhowever, the needle is in position and the ciamping nut is screwed down, its jaws 7 are forced inwardly by the tapered portion of the clamping nut against the needle. The tighter the clamping nut is screwed down, the farther the jaws 7 will project into the tapered portion of the clamping nut, and; consequently, the split cylindrical jaws eonstituting the cylindrical portion 8, will be The socket of the'grooving portion 8, will thus be clamped tightly in position. The grooving-tool can be ad justed rotatively or vertically in any desired position, and by screwing the clamping nut down, the grooving-tool will be locked in such adjusted position.
What I claim is: t
1. In a device of the character described, the combination with a needle bar adapted to receive a needle, a clamping nut one end of which is slotted to form expansible jaws, and a grooving tool mounted on said expansible jaws and adapted to be gripped thereby.
2. In a device of the character described, the combination of a needle-bar, having tapered clamping jaws, a clamping nut cooperating therewith the upper end of which clamping nut is slotted to form an expansible mount for a grooving-tool, and a grooving-tool mounted. on slotted portion of said eXpansible mount.
3. In a device of the character described, the combination of a needle bar having tapered clamping jaws and threaded portion, a clamping nut, having a tapered bore for coiiperating with said clamping jaws and being provided with a threaded portion to engage the needle-bar, said clamping nut also havin splits at the end containing the tapered bore, said, split end being designed to receive the socket of a grooving-tool, and a grooving-tool for cotiperating with said split end. I
4:. In a device of the class described, the combination with a needle bar adapted to receive a needle, a clamping nun adapted to signature in the presence of two Witnesses, be applied to the needle bar the upper end this 16th day of February, 1911. V
