UNITED STATES PATENT OFFICE.
ARTHU R RICHARDSON, OF READING, MASSACHUSETTS.
WAX-TH READ SEWING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 398,653, dated February 26, 1889.
Application filed August 13, 1888.
To all whom it may concern:
Be it known that I, ARTHUR RICHARD- SON, of Reading, county of Middlesex, State 5 of Massachusetts, have invented an Improvement in Var; -Thread Sewing-Machines, of which the following description, in connection with the accompanying drawin s, is a specification, like letters on the drawings representing like parts.
This invention is an improvement on that described in United States Patent No. 377 ,46 6, granted to me on the 7th day of February, 1888. In the patent referred to the cast-off bar is described as being contained in a groove in the needle-bar by means of the post in which the needle-bar and the cast-off bar slide. In this my present invention I retain the narrow support on which the work rests while being stitched, the said support being at the upper end of a post located at one side of the needle-bar, the cast-cit bar being dovetailed into a dovetail slot in the needle-bar. Preferably the post will be located close to one side of the needle-bar, so as to aid in supporting the needle-bar during its reciprocating movements.
Figure 1 is a front elevation of a sufficient portion of wax-thread sewing-machine to enable my invention to be understood, the presser-foot being omitted. Fig. 2 is an enlarged sectional view of the needle-bar and i post with the support at its upper end, the needle-bar and support or throat being partially broken out at its upper end. Fig. 3 is a top view of the support or throat; and Fig. -l is a section in the line :11, Fig.
The frame-work A, the vibrating head B, pivoted at B and carrying in it the reciprocating awl-bar B having an awl, h, and the presserba-r B the thread-guide c, and the rock-shaft C, jointed by a link to and to move the head B, are all as common in wax-thread sewing-machines wherein the work is fed by the awl.
The frame-work has erected upon it a post or upright, (I, having at its upper end a narrow support or throat, (1, so as to support a sole very near its outer edge and very close to the needle 6, carried. by the needle-bar e, which is reciprocated from a rock-shaft and link, all in usual manner.
Serial No. 282,604. (No model.)
The needle-bar grooved at one side from its upper to or nearly to its lower end, the said groove being undercut of such shape as to receive within it the castoit' bar f and retain the same therein, the groove and cast-off bar being herein shown as of dovetail shape in cross-section, a groove and bar of such shape acting to prevent the lateral escape of the cast-off bar fitted to it.
I do not desire to limit my invention to the exact form in cross-section of the groove and cast-off bars so long as the ncedlc-bar and cast-off bar are of such shape that the cast-off bar is contained in the needle-bar and is not held therein by a pin or independent device which does not reciprocate with the needlebar, as the needle-bar might have an under out groove T-shaped or circular in cross-see tion, and the cast-off bar be correspondingly shaped to fit in said groove, and thus be held therein by the inwardly extending or converging walls or flanges at the sides of the groove.
The cast-oft bar is provided with a shank, g, extended in usual manner through a lug, g, carried by the needle-bar, and the cast-oflf bar is moved up and down by the said lug acting against stop collars g y in usual manner, the extent of lost motion between the lug and stop-collars to determine the stroke of the cast-off in the needle-bar being dctermined by adjusting the said stop-collars.
In the drawings I have shown the post as ooncaved next the needle-bar to enable the needle-bar to travel closely in contact with and be guided by the post; but I do not de sire to limit my invention to so locating and shaping the post as to act as a guide for the needle-bar, for, if desired, the post may be so located that the needle-bar will reciprocate near but not touch the post.
The needle is held in the needle-bar by a screw.
The upper part of the post, just below the throat-plate, maybe provided with fenders, as 2 3, to prevent the end of the necdlebar and the cast-off from accidentally striking the i work should it be bent or twisted under the throat.
The machine herein described is especially adapted for sewing the soles toihe uppers of shoes, the uppers being right side out.
I claim- 1. Inawaxdzhread sewingmaehine, the 001m binatio11,witl1 a W0rk-support, of a needle-bar having an undercut groove and a cast-oft bar fitting in said groove and retained therein by the inwardly extend in g or converging walls or flanges at the sides thereof, substantially as described.
2. The narrow post having its inner face grooved to guide the needle-bar at one side, and having the support or throat, combined with the needle bar having an undercut groove, and the cast-oiibar fitting in said groove and retained therein by the walls or flanges at the sides thereof, substantially as described.
3. The post having the narrow throat or support for the sole adjacent to the needle and the fenders 2 33, combined with the needlebar having the undercut groove and the cast-- off bar fitting in said groove and retained therein by the Walls or flanges at the sides thereof, substantially as described.
In testimony whereof I have Signed my name to this specification in the presence of two subscribing witnesses.
ARTHUR S. RICHARDSON.
