MACHINE FOR SEWING ON BUTTONS.

SPECIFICATION forming part of Letters Patent No. 431,832, dated July 8, 1890.

Application filed October 12, 1888. Serial No. 287,878. (No model.)

means whereby the before-mentioned results.

may be accomplished by a single motion or movement of the operator.

My invention is particularly applicable to machines for sewing on buttons, and is herein shown and described as adapted to be embodied in such machine, though it will appear obvious that it may be applied to sewing-machines equipped for other purposes.

Reference is to be had, for afull understanding of the invention, to the accompanying drawings and the letters of reference marked thereon, forming a part of this specification, the same letters designating the same parts wherever they occur, of which drawings Figure 1 is a side elevation of a button-sewing machine equipped with my improvement. Fig. 2 is a front end elevation of the same. Fig. 3 is a vertical cross-section taken on a line rnnnin g through the point at which the presser-bar is connected with the button holder and carrier, the upper part of the machine being omitted. Fig. 4 is a sectional view taken on the line y y of Fig. 1. I

It is common in sewing-machines adapted to sewing buttons on fabrics, &c., to so set the button holder or carrier as that it may be reciprocated to have sewing accomplished through two eyes of a four-hole button, and then be automatically shifted to another position to have sewing accomplished through the other two eyes of the button, when the machine will be automatically stopped. A machine thus organized is shown and described in my application for Letters Patent of the United States, filed the 6th of May, 1887, Serial No. 237 ,294. Means are shown and described in said application for setting or latching the button holder and carrier in a certain position, shifting it automatically to another position, reciprocating it so as to have the needle of the sewing mechanism operate first through one-eye and then another of a pair of eyes of a button, and for automatically stopping the machine after the sewing on of the button shall have been accomplished. Reference may be had to my aforesaid application for a full understanding of the construction, arrangement, and functions of the mechanism mentioned, my present invention being, as has already been stated,

concerned onlyin means for raising the presser-bar and button'holder and carrier, releasing the tension on the thread, and moving the button holder or carrier so as that it may be set or latched in operative position by any suitable means.

In the drawings, A designates the bed of the machine; B, the overhanging arm; O, the main shaft; D, the needle-bar-operating rockshaft; E, (in dotted'line,) the link or pitman connecting shaft 0 with rock-shaft D; F, the needle-bar; G, the presser-bar; H, the driving-pulley; I, the clutch mechanism co-operating with-the driving-pulley; J, the button holder and carrier, connected with the presserbar G by means of a link G, and K a rod or pitman by which the button-carrier J is reciprocated. All of the parts mentioned may be the same as those shown in my aforesaid application for a patent.

a designates a lever pivoted at b to any suitable part of the machine, and provided with a lug or angular part c, arranged to operate in a slot at of a slide or block 6, connected by means of the stud f with the button-carrier J, so that by depressing the outer end of lever a the button-carrier J may be moved in the direction of the arrows, Figs. 2 and 3, for the purpose of setting or looking it in position, as before mentioned, and as explained in my aforesaid application.

19 represents a lever pivoted at p to the overhanging arm, and projecting at its inner end under a stud q projecting out from a collar q secured to the presser-bar G, and between which collar and a fixed sleeve r, forming the upper bearing and guide for the sliding presser-bar, is arranged on said presserbar the spring 8, which operates to press the presser-bar downward.

t indicates a rocking rod journaled in suitthe overhanging arm and journal-stud of the tension-disk 1), and bears against the inner face of the disk 10, against which the tensionspring 20 bears to retard the rotation of tension-disk Q), as is well understood by all having a knowledge of sewing-machines.

WVhen'now the presser-bar G is raised by the depression of the outer end of lever 19, the upper end of the presser-bar, acting on iinger t, will effect a rocking of bar t, actuating finger u so as to press rod or wire 1) rearwardly, pressing back disk to against spring to, resulting in a complete release of the ten- S1011 when the presser-foot is raised, permitting the thread to run freely through the eye of the needle in order to permit of the removal of the work and beginning anew the operation of sewing on a button. To the outer or forward end of lever 10 is attached a rod or wire 2, which may be connected with a suitable treadle (not shown) on the floor, or attached to the machine and adapted to be depressed by the foot of the operator in order to raise the presser-bar and release the tension, as aforesaid; and to move the button-carrier, through the medium of lever a, by the same movement that is employed to raise the presser-bar and release the tension on the thread, I pass the rod or wire 2 through a hole 2' in the outer end of lever a, and secure a collar 2 to said rod 2 at a proper polnt above said lever a, so that by drawing down on wirez to raise the presser-bar collar 2 will be brought to bear on the outer end of lever a, and depress the same, with the result of moving the button holder and carrier, as hereinbefore explained.

It is obvious that changes may be made in the form and arrangement of parts comprising my improvement without departing from the nature or spirit of the invention.

WVhat I claim is l. The combination, with a presser-bar provided with a laterally-projecting lug, and a button holder and carrier, of a lever 19, having one end extended under said lug on the presser-bar, a lever 64, provided with a hole in its outer end, a slide with which one end of the latter lever is connected, said slide being connected with the button carrier and holder, a rod or wire connected at its upper end with the outer end of lever 19, and passing through the hole in the outer end of lever a, and a col lar clamped on said rod or wire above lever a, whereby by drawing down on the rod or wire the presser-bar will be raised and the button holder and carrier moved, substantially as set forth.

2. The combination, with the overhanging arm, of a presser-bar provided with a later ally-projecting lug, a rock-rod provided at its forward end with a finger having its free end extended over and resting upon the upper end of the presser-bar, a tension mechanism, a rod or wire '0, constructed and arranged to rest against the tension mechanism to release the same, a finger secured to the rear end of the rock-rod, having its free end arranged to operate against the end of rod or wire 1), a lever 19, having one end extended under said lug on the presser-bar, a lever provided with a hole in its outer end,a slide with which one end of the latter lever is connected, a button carrier and holder with which said slide is connected, a rod or Wire connected at its upper end with the outer end of lever 19, and passing through the hole in the outer end of lever a, and a collar clamped on said rod or wire above lever a, whereby by drawing down on said last-mentioned rod or wire the presserbar will be raised, the tension released, and the button holder or carrier moved, substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 30th day of August, A. D. 1888.

LINGAN O. WVING. Witnesses:

ARTHUR W. ORossLEY, W. O. RAMsAY.
