OF NEW YORK, N. Y.
SPECIFICATION forming part of Letters Patent No. 667,712. dated February 12, 1901.
Application filed May 2,1900. Serial No- 15,l86. (No model.) I
To all whom it may concern:
Be it known that I, HERMANN A. KLEMM, a citizen of the United States of America, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Take-Up Apparatus for Sewing-Machines, of which the following is a specification.
My invention consists of improvements in the construction and arrangements of takeup apparatus for the needle-thread in sewingmachines, as hereinafter described, reference being made to the accompanying drawings, in which Figure l is a side elevation of a sewingmachine with part of the front side of the case detached, showing the application of my improved take-up apparatus. Fig. 2 is a side view of the take-up apparatus and part of the needle-bar and its connections with the neetile-operating lever, detached and enlarged, with a part of the head of the needle-bar and presser-supporting arm in section. Fig. 3 is a plan view of the take-up apparatus with some parts in section.
A represents the base portion of the ma chine, which is suitably inclosed. a represents the hollow needle-bar and presser-sup porting arm with its front plate removed. 0 is the needle-bar-Working lever. It is pivoted at c and connected at the end of its short arm by rod with an eccentric (not shown) on the driving-shaft g, as usual. h is the needle-bar. It has a short arm 7 clamped to it, one extremity of which is coupled by a linkj with the end of the long arm of the needle-bar-working lever, and the other end of said arm 11 works in a slot of the head Z of the supporting-arm afor guiding the needle-bar properly. All these parts, however, are of common form and are not claimed herein.
The take-up apparatus which is the subject of the claims is constructed and arranged as follows: A lever on is pivoted at n to a bracket 0, attached to the under side of the top plate of arm a. One arm of said lever reaches forward through a slot 19 in the head Z of said arm (L and has an eye q, through which the thread 3 is strung, and the threaded end of said lever-arm plays up and down between two perforated thread-guides 25, through which the thread is also strung, said thread being the take-up lever.
led from the tension device and spool through a guide 9, which is adjustable vertically, also through an eye 10 in the upper end of the needle-bar h and through a fixed guide 11. The other rearwardly-extending arm of said take-up lever has a cam-slot u, in which a stud 22 Works, which is carried on one side of a rocking disk 20, pivoted at .70 on a branch y of bracket 0, the end of which is attached to a lug 2 of the lower plate of said supportingarm a. The rocking disk to has a radial slot 2, in which a stud-pin 3, carried in one side of the lever 0, works to cause the stud-pin o to traverse the cam-slot u, and thus operate The form of the cam-slot and the location of the stud Q) on the rocking disk are gaged in the proper relations with the movements of the needle-bar for timing the operations of the take-up with the needle, as usual in such cases.
The essential advantage of the apparatus is a contrivance of mechanical parts of simple construction, easy operation, and durability in service.
A take-up device for a looper-thread 4 is represented at 5 in connection with a reciprocating looper 6 and a looping-hook 7, used in connection with the needle 8; but these are not claimed and need not be further described.
Any suitable arrangement of thread-guides may be employed, and I do not mean to be limited to the arrangement of guides shown.
What I claim as my invention is The combination with the supporting-arm of a sewing-machine the needle-bar-operating lever, and suitable needle-thread guides, of the takeup lever pivoted intermediately of its ends on the supporting-arm with its threadcarrying end in suitable relation With Said thread-guides, and having the cam-slot in its rear arm, the rocker-disk also pivoted on the supporting-arm and having the stud-pin engaging the cam-slot of the lever, also having the radial slot, and the stud-pin of the needlebar-operating lever engaging said radial slot.
Signed at New York city, New York, this 30th day of April, 1900.
HERMANN A. KLEMM.
