SEWING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 240,324,. dated April 19,1881. Application filed April 19, 1880. (No model.)
To all whom it may concern:
Be it known that I, NIoHoLAs MEYERS, of the city of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Sewing-Machines, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to an improvementin the construction of the presser-foot of sewing- IO machines, whereby the pressure which is exerted upon the footby its spring can be readily regulated.
' My invention consists of the particular construction of the pressure-regulator, which will T5 be hereinafter fully described.
In the accompanying drawings, Figure 1 is a perspective view of the head of a sewingniachine provided with my improved presserfoot. Fig. 2 is a sectional elevation of the same.
Like letters of reference refer to like parts in the several figures.
A represents the head-plate of a sewing-machine; B, the front end of the arm 0, the nee- 2 5 dle-bar, and J) the presser-foot, all of ordinary and well-known construction.
(1 represents the vertical rod or bar, which is secured to the presser-ibot and guided in recesses in the contiguous faces of the head-plate 3o Aand arm B on one side of the needle-bar, in
the usual manner.
6 represents a spiral spring, which surrounds the upper portion of the rod d, and which rests with its lower end upon a shoulder or stud,f,
3 5 formed on the lower portion of the rod (1, or otherwise secured to the rod. The stud projects through a slot, g, in the contiguous faces of the plate A and arm B, for the purpose of retaining the presser-foot in its proper position.
H represents the tightener, by which the pressure is regulated which the spring 0 exerts upon the presser-foot. The tightenerH consists of a depending arm, h, arranged 011 the front side of the plate A, and having its upper end turned backward through a vertical slot, h,in 5 the plate A, and provided with a perforation, through which the rod d passes loosely. The perforated upper end, W, of the tightener rests on the spring 0, and slides loosely on the rod 01. The arm h is provided on one of its vertical sides with a series of hooks, 6, either of which can be engaged with a stop or stud,j, which is secured to the face-plate A. By depressing the tightener H the tension of the spring is increased, and by raising it the tension is reduced. The upper end of the tightener fits loosely on the bard, to permit a limited sidewise movement of the tightener sufficient to permit the same to be engaged with or disengaged from the stud j.
By my improved mechanism the tension of the spring is more quickly adjusted than by a mechanism in which a screw-thread is employed, and the degree of the tension applied to the spring is always apparent by the position of the tightener. The tension of the spring caused by the downward movement of the tightener is not only apparent to the eye, but
is readily felt by the hand of the operator, so that the tightener may be hooked over the pin at the proper point to avoid undue or unnecessary pressure.
I claim as my invention- The combination, with the head-plate A, provided with a stud,j, ot' the presser-foot and rod 7 5 D (1, spring 6, attached to the rod 01 at its lower end, t-ightener H, titted loosely on the rod agd resting on the upper end of the spring a, an'
hooks 71, formed on one side of the tightener H and adapted to engage with the studj, substantially as set forth,
