CHARLES E. TIBBLES, OF CHICAGO, ILLINOIS, ASSIGNOR TO THE TIBBLES MANUFACTURING COMPANY, OF SAME PLACE.
TENSION-SPRING FOR SEWING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 328,540, dated October 20, 1885.
Application filed May 14, 1885. Serial No. 165,410. (Model) T aZZ whmn it may concern.-
Be it known that 1, CHARLES E. TIBBLES, of Chicago, in the county of Cook and State of Illinois, have invented a new and 1m- 5 proved Tension-Spring for Sewing-Machines, especially adapted for thread-controllers; and
I hereby declare the following to be a full,
clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in
which- Figure 1 is an enlarged side elevation of the improved spring secured to the bottom of the head of the machine, which is shown in sec tion. Fig. 2 is a bottom plan view of the spring attached. Fig. 3 is a bottom plan view of a modification. Fig. 4 is a sectional view of the spring, showing the manner in which it is coiled.
My invention has for its object to provide a tension-spring for sewing-machines, which will have great elasticity with minimum dimensions, and which can be secured and adjusted readily and economically.
To this end my invention consists of a wire spring having one end free through which the tension is applied and wound in the coils, so that the other end of the wire, to which a resisting fastening is applied, will lie in about the 0 same plane with the free end, and thereby the tension end can work closely against the face to which the spring is secured, as will hereinafter be fully described and specificially pointed out in the claim.
In order that those skilled in the art may make and use my invention, I will proceed to describe the exact manner in which I have carried it out.
In the said drawings, D represents the bot- 0 tom of the head of a sewing-machine, in which is cut a cylindrical recess, D, to receive the coils of the spring through which passes a bolt, B, having a screw, B, at its lower end which enters a tapped hole at the bottom of 5 recess D, and holds the spring in place against the head of the machine.
The spring is made as follows: commencing at end 11, leaving length sufficient to create a fastening by turning down the extreme end at a right angle, as shown, a coil, C, is made of a desired length, and then an exterior coil, 0, is continued back around theinterior coil, C, to a point where the first andlast bends of the two coils lie in the same plane, and the spring-bar or end A is in the same plane and substantially opposite to the fastening or stationary end a ofthe spring. The outerend of springbar A is provided with a bent eye, a, or other desirable engaging device.
This construction of spring enables me to to secure it adjustably, with great economy in construction, so it will work closely to a fiat surface.
In the plate or head to which thespring is secured I provide a series of holes, I) b, equi- 6 distant from the center of screw 13, into one of which the bent rectangular end a of the wire is thrust when the spring is placed and screw B set. The changing of the end a from one hole I) to another changes the tension on the spring in a given throw of the eye a.
In the modification shown in Fig. 3 the secured end of the spring is provided with an eye, a, to receive a pin which passes into one of the holes I).
In this instance I have illustrated the spring as attached to the lower face of the head of the sewing-machine immediately above the needle, and acting as a thread-controller, the thread passing through loop or eye a before passing to the needleeye; but it is evident that the constructionof spring described and claimed may be applied to other parts of machines as a tension device without departing from the spirit of my invention, and that the end of the interior coil may be secured in various ways.
Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is
The tension-spring having the interior coil 0 and oppositely-Wound exterior coil, C, in combination with a sustaining-plate provided with recess D, and the holding-screw B B, substantially as set forth.
CHARLES E. TIBBLES.
