TAKE-UP FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 377,516, dated February 7, 1888.

Application filed December 3, 1887. Serial No. 256.885. (No model.)

To all whom it 17mg concern:

Be it known that I, EMILIO QUEROL Y DEL- GADO, a subject of the King of Spain, at present residing in the city of Brooklyn, county of Kings, and State of New York, have invented new and useful Improvements in Take- Ups for Sewing-Machines, of which the following is a full, clear, and exact description.

My invention relates to a sewing-machine for which I filed application for Letters Patent of the United States under date of J anuary 21, 1887, Serial No. 225, 024. V

The object of the invention is to provide a new and improved take-up which is simple and durable in construction and very effective in operation. f

The invention consists in the construction and arrangement of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied to a sewing-machine, with parts in section. Fig. 2 is a sectional end elevation of the same on the line at x of Fig. 1. Fig. 3 is a face view of the presser-bar, the needle-bar, the take-up mechanism, and the casing in section; and Fig. 4 is a sectional plan view of the same on the line yy of Fig. 3.

A is the casing, provided with the hinged bed-plate A; and B, the main shaft on the under side of the bed-plate and carrying the driving-pulley B and the fly or hand wheel 13*.

O isa cam-wheel on the shaft 13, with which the lower end of the bar D engages. Theupper end of the bar D is provided with a socket, D, in which fitsthe end of the needle-bar D the said needle-bar being pivoted at D to the arm E. The feed-dog J is secured to the feedbar J, pivoted at J and provided with the lug J engaged bythe cam J on the rod J, having a beveled end, J

J is an arm secured to the rod J and engaging the cam-groove K of the cam K.

L is a rod provided with a pin, L project' ing through a slot of the bed-plate, and provided with a button, L, for. regulating the amount of'feed.

N is a cross-head supporting the shuttle-carriers O, and provided with a pin, N, which passes into the forked end'of the arm Q of the' bell-crank leverQ, pivoted at Q to the under side of the bed-plate.

The other arm," Q of the bell-crank lever is pivotally connected to I a slide-bar, R, which is to be provided with a pin for engaging the cam-groove C of the cam O.

E is a head on the end 'ofthe arm E, and to Y the lower end of the said head "are secured the tension devices H. I I

Each of the tension devices consists of a spring-bar, H, having a half-round end fitting in a correspondingly-shaped head, H having a notch, H, in itsupper edge. The tension is regulated by the bolt and nut H.

The head E is provided with aremovable front plate, E, andin the said head E is held, to slide vertically in suitable bearings, the needle-bar F, provided with a lug, F", operating the take-up mechanism G. The latter consists of the vertically-sliding bar or rod G, mounted in suitable hearings in the said head E and having alug, G", against which presses the lug F of the needle-bar F in its descent.

The upward motion of the rod G is cansed'by the spring G coiled on the said rod G, and resting with one end on one of the bearings, while its other end-abuts against a collar, G, on the upper end of the said rod G.

On an enlarged part of the rod G are pivoted the take-up arms G projecting sidewise but in opposite directions through slots in the ends of the head E a normally-horizontal position by the tensionsprings G, each secured by one end to the bar A G, and having its other free end pressing against the pivoted end of the respective arm G Each of the latter is provided with an eye, G through which eyes pass the needlethreads T and T.

The operation is as follows: The needle-bar F derives its vertical sliding motion from the main shaft, and in its descent presses with its lug F on the lug G of the rod G, whereby the The said arms G are held in take-up mechanism is carried downward with the needle-bar F, so as to permit the lower ends of the threads T and T to follow the needles held on the needle-bar. When the latter is on its upward stroke, then the take-up mechanism G exerts a pull on the threads T and T, which are thus unwound from their respective bobbins. The lower ends of the threads T and T are held in the cloth to be sewed,andthetensionmechanismsHH,located below the take-up mechanism G, prevent a too rapid unwinding of the threads T and T from their respective bobbins, and also prevent breakage of the threads. The springs G", pressing against the take-up arms G also act as an additional tension and serve to avoid breakage of the thread in both the up and down motions of the needle-bar F.

The tension device and the feeding devices herein shown and described form no part of this application, they being made the subject of separate applications numbered 256,886 and 256,887, respectively.

ing the lug G against which operates the said lug F, the spring G, operating on the said rod G, the take-up arms G pivoted on the said rod G and having on their outer ends the eyes G and the tension-springs G, holding the said take-up arms in position, substantially as described.

2. The combination, with the rod G and means for reciprocating the same, of the arms G pivoted to said rod G, and each provided with an eye in its free end, and the springs G, secured to the said rod G, and having their free ends bearing upon the pivoted ends of the said arms G substantially as described.
