n Inman/ibn' 1 @zeg NITED STATES PATENT OFFICE.
PHILIP DIEHL, OF ELIZABETH, NEV JERSEY, ASSIGNOR TO THE SINGER MANUFACTURING COMPANY OF NEW JERSEY.
NEEDLE-CLAMP FOR SEWING-MACHINES.
SPECIFICATION Y forming part of Letters Patent No. 464,013, dated December-1, 1891.
Application iiled July 24, 1891. Serial No. 400.576. (No model.)
To all whom t may con-cern:
Beit known that I, PHILIP DIEHL, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Iniprovements in Needle-Clamps for Sewing- Machines, of which the following is a specifif cation, reference being had therein to the accompanying drawings.
My invention has for its object to provide an improved needle-clamp and thread-guide for sewing-machine needle-bars of such construction that different-sized needles may be securely held in place by the clamp, and the clamp be retained on the needle-bar by the thread-guide so that the said clamp cannot slip off from the said bar when the needle is loosened. To this end I attach to the lower end of the needle-bar a thread-guide having an eye through which the needle loosely passes, and which is slotted so as to be easily threaded, said thread-guide extending beneath the needle-clamping collar in such a manner as to prevent the said collar from coming off the needle-bar when the set-screw is loosened, and the needle-clamp or clampingcollar is provided with a V-shaped groove to co-operate with the needle-receiving groove formed in the needle-bar, all as will hereinafter be more fully described.
In the accompanying drawings, Figure l shows a portion of a needle-bar with iny irnprovement applied thereto and with the needle in position. Fig. 2 is avertical section of the saine. Figs. 3 and 4 are horizontal sections on line m, Fig. 1, showing differentsized needles in the clamp 5 and Fig. 5 is a detail perspective view of the thread-guide and its shank.
A denotes a needle-bar partly cut away at its lower end and provided on one face with a concave groove a for the reception of the shank of the needle a. The needle is secured to the needle-bar by a clamp or clamping-collar B, held in place by the set-screw b, the said clamp or clamping-collar having in its inner C is thethread-guide, the shank of which is attached to the needle-bar by the set-screw c, the said thread-guide being bent nearly at a right angle to its shank so as to extend beneath the needle-clamp 'and the lower end of the said needle-bar, the said bent portion being provided with an eye d loosely surrounding the needle and preferably open or slotted, as shown, so that the thread may be readily drawn into the saine. The thread-guide, extending thus beneath the needle-clamp, serves to prevent the latter from slipping off from said bar when the set-screw b is loosened for the purpose of removing the needle, and the inconvenience heretofore frequently arising with needle-clamps similar to that herein shown will thus be avoided.
The V-shaped groove b in the needle-clamp co-operating with the rounded or concave groove a in the needle-bar enables needles having different-sized shanks to be properly centered and to be securely held in place, as will be readily understood by reference to Figs. 3 and 4.
The shank of the thread-guide C is preferably provided with ahole copposite the clampholding set-screw b, and into and through which the inner end of the said set-screw extends to impinge against the needle-bar, and when thus constructed the engagement of the said inner end of the said screw with the shank of the thread-guide will prevent the needle-clamp from dropping when said setscrew is but slightly loosened; butshould the said set-screw be accidentally turned out far enough to-disengage its inner end from the said hole c the thread-guide extending beneath the said clamp will prevent the latter from dropping off from the needle-bar, as hereinbefore described.
I claim and desire to secure by Letters Patent- 1.' The combination, with the needle-bar partly cut away at its lower end and provided with a needle-receiving groove or recess, of a and the thread-guide C, attached to said nee- 1o needle-clamp, a set-screw for tightening the d1e-bar and provided with the hole oopposit'e same, and a thread-guide attached to the said said set-serewneedle-bar and extending beneath the said In testimony Whereoflaffix mysignatul'e'in r: clamp and the lower end of the needle-bar, presence of t-Wo Witnesses.
u and having an eye through which the needle PHILIP DlEI-IL.
loosely passes. Witnesses:
2. The combination, with the needle-bar A, J. G. GREENE,
of the needle-clamp B, having the set-screw b, l J. SAULS.
