GEORGE L. HUBBELL, or' BRIDGEPORT, CONNECTICUT.

HAND SEWIN G-MACHINE.

SPECIFICATION forming part of Letters Patent No. 402,597, dated May 7, 1889.

Application filed May 10, 1888.

To all whom it may concern.-

Be it known that I, GEORGE L. HUBBELL, a citizen of the United States, residing at Bridgeport, in the county of Fair-field and State of Connecticut, have invented certain new and useful Improvements in Hand Sewing Machines; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in hand sewing machines, and has for its objects, first, to provide means which shall be simple and positive in operation for the removing of the shuttle without the use of covers or plates in or upon the bed; second, to furnish a simple and effective feed for use in such machines, and, third, to adjust the recovery-spring of the handles so that it may be effective-and not connected directly to both of said handles; and with these ends in view my invention consists in the de tails of construction and combination of elements" hereinafter to be fully set forth and described, and then recited in the claims.

In order that those skilled in the art to which my invention appertains may fully understand how to make and use my improvement, lwill describe the same in detail, reference being had to the accompanying drawings, which form a part of this specification, in which- Figure 1 is a side elevation of a machine constructed in accordance with my improve ment; Figs. 2 and 3, plan views of the shuttle and feed mechanisms, the bed-plate being removed, but its shape being shown in dotted lines; Fig. 4, an edge view of the pivoted driving-plate, and Fig. 5 a detail side elevation of the feed-bar. I

Like reference-numbers denote the same parts in all the figures.

This application is in subject-matter like in many respects to that shown and described in Hubbell, July 27, 1886, Serial No. 209,266, and

this, to refer for purposes of illustration.

Rigid handle A, needle-arm B, and platesupporting arm 0 constitute the frame of the Serial No. 273,513. (NomodeL) D is the work-plate secured to the arm 0, as in the aforesaid application.

E is the needle-bar-actuating lever, pivoted at F.

G is the needle-bar.

H is the operating-lever, pivoted to the base of the needle-arm and connected to the lever E by link J Extension 0, cross-pin R, and slide-bar S are similar in operation to the same parts in the application above referred to. Upon the top of the slide-bar S is a flat-faced projection, 1, in the outer edge of which is formed a recess or pocket, 2.' 3is the driving-plate. It has a curved ordeflected driving-slot, at, which embraces the pin W on the carrier-bar U. The plate 3 is pivoted upon the projection 1, and is adapted to be turned thereon, as seen at Figs. 2 and 3. It has a projecting tooth or finger, 4, which,when in normal position, en-

gages the pocket 2, and a gl'aspinghandle, 17, whereby it may be turned.

5 is the feeding-lever, which is pivoted beneath the bed, as seen at 6, and which near its rear end is provided with a curved slot, 7. This curved slot is engaged by a pin, 8, on a projection which is secured on the slide-bar S. The forward end of this lever is hooked, as seen at 9, and encircles a bracket, 10, on the under side of the feed-bar 11. This bracket has an inclined surface, 12, and a projection, 13, on its under side, for the purpose presently explained.

The feed-bar is forked at one end, and said fork embraces a stud, 14, secured to a projection from the bed-plate. A spring, 15, is secured to the top of the bar and bears against the plate. The spring 16, which is secured as to one end by engagement with the rigid handle', has its other end coiled about a pin upon the link J. I r 4 .The'operation of my invention is as follows: When the handles are closed together by the grasp of the operator and the driving-plate is at position as at Fig. 3, the shuttle, by means of the engagement of the pin on the carrier-* bar with the curved slot in the driving-plate, .is, caused to make its segmental traverse beneath the plate, during which it takes the loop precisely as is shown and described in the application heretofore referred to.

machine' When it is desired to remove the shuttle for the changing of the bobbin or other purpose, the driving-plate is forcibly turned on.

its pivoted point, by means of the handle 17, to the position shown at Fig. 2. This movement of the plate forces the carrier-bar and shuttle beyond their regular limit of movement and beyond the edge of the work-plate, so as to expose the shuttle to view and admit of its ready removal. This dispenses with any need for an opening in the face of the work-plate.

By means of spring 15 the feed-bar is normally held downward away from the workplate, so that the serrated dog does not project above its surface. The spring aforesaid may be attached either to the plate or to the bar. In Figs. 2 and 3 it is shown in dotted lines as secured to the plate. In detail, Fig. 5, it is shown on the feed-bar. It is equally operative in either connection. The forked engagement of the end of the bar with the stud permits to the former a longitudinal play upon the latter. The curved end of the feed-lever is for the purpose of actuating said bar longitudinally in both directions, and by means of the incline on the feed-bar it also actuates it upward, so that the serrated dog engages the goods and moves them forward under the needle. In detail these movements are as follows: As the needle ascends, the feed-lever is moved upon its pivotal point, and as its hooked end traverses it first by contact with the incline raises the bar against the spring, and then, by engagement with the projection 13, carries the bar along longitudinally to the limit of its throw. As it recedes, the spring throws the bar downward, and the body of the lever, by engagement with the other side of the projection, carries the bar back into position for the next feeding operation.

I find it more advantageous to attach the recovery-spring for the actuation of the handles to the stationary handle and the link, respectively, since its connection with the pin on the link forms a point of positive attachment for one end thereof.

I claim- 1. The combination, with the stitch-forming and cloth-feeding devices of a hand sewingmachine, of a slide-bar arranged to reciprocate longitudinally beneath the bed-plate, a driving-plate pivoted upon the top of the slidebar and provided with a curved slot,whereby movement is imparted to the carrier-bar, a dctent for normally retaining said plate in its driving position, and means, as ahandle, for turning said plate upon its pivotal point, whereby the carrier-bar and shuttle are projected beyond their normal limit of traverse and the latter carried to a point outside the edge of the bed-plate, substantially as specified.

2. The combination, with the stitch-forming and cloth-feeding device of a hand sewingmachine, of the driving-plate having a deflected slot therein for the actuation of the shuttle and a toot-h and handle thereon, as shown, a projection or bracket upon which said plate is pivoted, said bracket having a detent for the tooth, and means, as described, whereby movement is imparted to the said plate, substantially as described.

In combination with the needle and shuttle and means for driving the same, the feedbar-operatin g lever having the curved slot near its heel end and the hook 9 atits other extremity, the reciprocating pin engaging said slot and actuating said lever, the forked feedbar pivoted as to one end and spring-actu ated away from the plate, and the incline and proj ection upon the feed-bar arranged within the field of the hooked end of thelever, and whereby said feed-bar is actuated in both directions, substantially as specified.

4. The combination, with the stitch-formin g and cloth-feeding devices of a hand sewingmachine, of the stationary handle, the movable handle, the needle-bar-actuatin g lever and the link between the latter and the movable handle, and the spring whose coils are arranged in a vertical plane and the ends whereof are connected, respectively, to the stationary handle and a stud on the link, substantially as shown and described.

5. The combination, with the needle-bar and means for driving the same, of the swinging shuttle-carrier and its shuttle, the pivoted driving-plate having a deflected slot and a detent engaging the base on which it is pivoted, the curved and slotted feed-lever hooked as to its outer end, and the forked, pivoted, and spring-actuated feed-bar having the incline and projection thereon,whereby, through the hooked end of the feed-lever, the goods are fed beneath the needle, asset forth.

Intestimony whereof I aflix my signature in presence of two witnesses.

GEORGE L. IIUBBELL.
