TO ALL WHOM IT MAY CONOERN:

Be it known that I, 13. W. COLLIER, of Oxford, in the county of Lafayette, and State of Mississippi, have invented a new and improved Hand-Sewing Machine; and I do hereby decla-re the following to be afull, clear, .and exact description of the nature, construction, and operation ofv the same,- reference beingihad to the accompanying drawing, which is made a part of thisspecication, and represents a perspective view of' my improved hand-sewing machine, the working surface or table being indicated in red outline, so as not to conceal the enclosedoperating mechanism.

'lhe nature of my invention consists in the arrangement of a bobbin'and looping-hook Within a case or box attached to one of a pair of levers or handles pivoted together and formed with finger-loops like thetwo parts of a pair oi' shears, the needle being attached to the corresponding end of the other lever-.and operated-V hy opening and closing the instrument by hund. The instrument is adapted to be carried about from place to place, and may be supported by the hand without serious inconvenience when in operation.

In order that others skilled in the art to which my invention appertains iii-.ty be enabled to fully understand and use the same, I will proceed to describe it in detail.

A A are a pair of levers pivoted together at a, and formed-at one end with loops B B, to enable them to be operated by the thumb and finger after the manner of shears. At their opposite ends these levers are provided with the ease or box O and the horizontal arm D. E is a looper, suitably' journalled within the-case C, and F is a hobbin arranged within the looper E. G (red lines) is the top oi' case G, upon which rests the matcrial to be sewed. H is the needle, adjustably secured to the end of the arm D, and occupying suoli position in relation to lthe mechanism E E F that when the levers are closed the needlel passes through its hole in the top G o? the case C, within which it leaves a loop to be caught by the hook and carried around the bobbin. I is the spool which holds the thread for the needle, said spool being niountezl'upon the lever A. The latter also supports the spring-tension pulley K, around which the thread extends from the spool to the needle. Ii is a pinion, iixed upon the shaft or axis of the looper E, and engaging with the seinicircnlar cog M, which 4is enclosed within the frame O, and `actu-ated by a rod, N, attached to the end ot lever A. When the llevers A A are closed the cog M is, by the action of the'rod N, made to rotate the looper E in one direction through the medium of the pinion L. The looper is rotated in an opposite direction, the needle is raised, and the levers opened, as often as the said levers are closed by hand, by the elasticity of the spring O. 'Ihe looper E is made to petorin a complete revolution in both directions,- that is to say, it has a reci'rocating motion upon its axis instead of a continuous rotary motion like the looper in the llVheeler and Wilson sewing machine; yet the looper,bobbin,.and make of stitch are analogous to those of the machine cited. .The downward motion of the needle-carrier D puts the needle through the cloth and turns the hook E backward in position to catch the loop of the needle-thread, and the upward motion causes the hook to take hold of the loop and pass it Aentirely around the bobbin, when the iloop becomes disengaged and the motion of the looper is reversed.

No feeding device is shown, as it is the intentiony to employ such as is used in the Wheeler and Wilson machine, or any other that may be lconveniently applied. I

Ilnving thus describedl my invention, the following is what I claim as new herein, and desire to secure by Letters Patent: i

I claim the combination of thelevcrs A A, B Il, ease O, arm I), needle II, rotary' looper E, hook E", b'obbin F, pinion Il, cog M, rod N, spring O, and spool I, all arranged as herein described for the piirpose specified.

B. W. COLLIER.
