TAKE-UP FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 254,788, dated March 14, 1862. Application filed June 23,1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. BAKER, of Cleveland, in the county of Cnyahoga and State of Ohio, have invented certain new and useful Improvements in Take-Ups for Sewing- Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to a take-up device for sewing-machines; and it consists in so constructing a take-up and needle-bar that both are operated by one and the same wrist or pin of a crank or crank-wheel; It also consists in a thread-retaining device, aswill be hereinafter set forth and claimed.

In the drawings, Figure l is adetached view of a face-plateof asewing-machine having my improved take-up attached, and looking at the said face-plate from the rear. Fig.2 isafront view of the crank-wheel which operates the needle-bar and my take-up. Fig. 3 is a side elevation of the crank-wheel, showingthe manner of operating the needle-bar and take-up. Fig. 4 is a view in section of a part of my take-up, showing the manner of threading the same.

A is a face-plate of a sewing-machine.

B is a heart-cam, which is attached to the needle-bar C and operated by means of ai'riction-wheel, a, on the wrist or pin 1) of the crank-wheel D. (See Figs. 2 and 3.)

E is a take-up, one end of the same being pivotally attached to the side of the face-plate A, or to an arm extending therefrom, as shown in Fig. 1, and the other end being provided witha-nysuitable thread-retainingdevice. The thread-retaining device shown, being the one I prefer to use, is formed by slotting one end 'of the take-up E both longitudinally and transversely, as shown more clearly in Fig. 4

of the drawings, and providing the longitudinal slot 0 with a spring, (1. The manner of threading this device is also shown in Fig. 4:. The spring (I is depressed, as shown by dotted lines, until it has passed the transverse slot 6.

til it reaches the enlargement at its lower end, when it has also reached the hook or turned end of the spring (I. The spring dis then released, and carries with it the thread, as shown.

The take-up E is operated by the wrist b on the crank-wheel D, and is provided with an irregular slot, as shown, in which the said \Vl'lst 1) works. The thread, after passing through the loop or eye at the upper side of the faceplate, as shown in Fig. l, is threaded, as hereinbefore shown and described, through the free end of the takeup, and from thence passes to the needle-bar and needle, and it will be seen that at each upward stroke of the needle-bar the take-up is also raised, and pulls with it the thread, and at each downward stroke of the needle-bar the take-up is lowered, as shown by dotted lines in Fig.1, and the thread is loosened between it and the needle.

What I claim is-- 1. Thecombination", with a tak -up lever the free end of which is provided with intersecting longitudinal and transverse slots, ofa spring having its free end located within the longitudinal slot in thearm, the lower end of the spring having a thread-retaining hook formed thereon, substantially as set forth.

2. The combination, with the needle-bar, a cam attached thereto, a rotary shaft, and (ran kpin for imparting a reciprocating movement to said needle-bar, of a take-up lever pivoted at one side of the needle-bar, and located between the crank-pin disk and needle-bar cam, andonstructed with an arc-shaped .-lot,within which engages the crank-pin, which latter imparts motion in both directions to the takeup lever, substantially as set t'orth.

In testimony whereof I have signed my name to this specification in the two subscribing witnesses.

' GEORGE W. BAKER.
