Letters Patent No. 109,753, dated November 29, 1870.
IMPaovEMENT IN NEI-:CLES AND 'rHElR cARRvlNe-ARMS Fon sEwlNGf-MAeHmEs.
The Schedule referred to in these Letters Patent and making part of the same.
To all lwhom itmay concern.
Be it known that I, CHARLES HENRY' PALMER, of the city of New York, in the county and State of New York, have invented new and useful Improvements in Sewing-Machines; and I do hereby declare that the following is afull, clear, and exact description thereof,
.which will enable others skilled in the art to make to slide vertically.
l Similar letters of reference indicate corresponding parts. l
A represents a needle split or dirided from the eye upward for admitting the thread from the hole B, and provided with flat or laterally-bent arms or shanks, C, at the upper' end for attaehment to the needle-arm by a clamp, D, being the same thus far as described in the patent'granted to Mary l. Carpenter January 25,
1870, in xvhich the needle is held by clamping` the parts G between the plane faces of thc,clamp D and the arm or needle-post E; and itis stated in thc said patent that the two parts of the needle may be adj usted to the requisite distance apart below the parts C by placing a piece of paper about the thickness of the thread between them, and closing them against it previous to screwing down the clamp. Y rlhe needles being held between two plane surfaces, as represented in the said patent, are'not earsilyadjnsted to the right position, great care being required to prevent .moving them to right or left of the true line when screwing up the clamp. It is also difficult t0 adjust them to the right height.-
. I-have therefore provided the grooves ,F for the parts C, one on each side of the slot H, preferably n'tlie face of the needle-arm or post, which grooves, together with the saidparts .0, 1 so adjust that when engaged in the said grooves the needles will not only be in the exact line, .but the spacebetween the parts; also the height will be regulated.v
The said grooves may be made in the clampingplat'es, but I prefer to make them in the post or needlearm, as stated.
Having thus described my invention,
I claim as new and desire to secure hy Letters Patent-4 y 'lhc arm E, having grooves F F, combined as de scribed wit-h the divided needle and the clamping de vice, for the purpose specified.
CHARLES HENRY PALMER.
