"IMPROVEMENT IN SEWIlfIG-MACHINE FOR WORKING- BUTTON-HOLES,

The Schedule nefcrrad to in these Letters {Patent and making part of the same.

To all whom it may concern:

Be it known that we, JAMES A. HousE and HENRY A. HOUSE, both of Bridgeport, in the county of Fairficld, and State of Oomieoticut, have invented certain new and useful Improvements in Sewing-Illac'hines, of

which the following is a full, clear, and exact descripzigzag'stitch is formed loyimpartiug method of combining, withja sewing-machine, mech- 'suilicient quantity of the UnitedStates anism, arranged below tlie'cloth platajto drawofi" needle-thread to allow for the vibrations of the cloth, and, as the needle is about to enter 'the cloth, to slacken thathread, to prevent it from drawing the needle'aside.

The accompanying drawings make part of this specification, and show our invention as adapted to a Wheeler & Wilson machine, and also to a machine for making button-holes, forwhich Letters Patent of No. 55,865, and July 10, 1866, No. 56,224.; p v Figure l represents a plan hr top view of our -improved machine;

Figure 2 represents a view of. the mechanism, as

seen'frombelo'w;

Figure 3 represents alplanof the vibrating clothplate detached;

Figure 4 represeuts'a vertical transverse sectionthrongh ,thesame, at the line mo: of fig. 3;

Figure .5'represents-a vertical longitudinal section at the. line 3] y of fig. 3;

Figure6 represents a view, partly in section, of the a-"gnachine, as seen from one end;

Figure 7 represents a similar view from the opposite end'; and

Figure 8 represents'a rear view of the vibrating take-up detached. v

The construction and operation of our machine, with the exception of the take-up, which forms the subject of the present claim,are so clearly showrgaud described in our aforesaid patent, No. 55,865, of June 26, 1866, thatwe deem it unnecessary here to do more than refer to the severalparts.

- The-mechanism is mounted in a cast-iron frame, A, of the .Iivell-known Wheeler 85 Wilson form and construction. 4

The needle-arm B is vibrated vertically, in the are of a circle, by well-known devices.

The table 0 is' secured rigidly to the frame, and slottedlongitudinally,

to receive the feed-screw D, 2,

relates to that class of sewing-mav being sewed, a lateral reciprocating p which has a slotted 'l head, l, on its 7' "A setscrew, 1}, passes through this slot, into the were granted to us, June 26, 1866, v v

I which is secured to a plate, E, vibrated on a fulcrum,

e, by a jog-bar, F, fig. 2, operated by a switch-cam on the spooling-pin, as fully explained in our patent aforesaid. v

As this machine is more especially designed to work button-holes, the cloth is held, by a spring-clamp, G, fig; 1, upon a revolvable bed-pla e, H, which vibrates with the table, and is turned, at proper intervals, by

Jwell-known means.

Y The take-up ismounted on a lever, I, pivoted, at i, to the under side of the frame,

intervals, by means of a cam, J, on the spooling-'pin.-

and vibrated, at proper This cani is, by preference, formed on the which carries the pins which move the star-wheel d, on the feed-screw D, as'describedin our former patent. (See' fig. 2.)

take-up L out of the way when not acted upon by the cam J. i I

Thetake-up, in this instance, consists of a bar, L, to the lever I,

figs. 2 and 8, arraugjd transversely forward end.

take-up, which can thus be adjusted laterally, and firmly held in any, desired position. 1 v

The front inner end of this take-up is rounded, and provided with ahoolr, Z the proper moment.

The bobbin or hook M, fig. 6, used, being the same as that shown in our former patents, needs no description here.

The operation of the machine will readily be undera stood. y

The cloth is held by the button-hole-shaped clamp, within which the needle works; is fed forward,-..at proper intervals, by the screw, and vibrated laterally, at proper intervals, relatively jog-bar. I

In this machine, the place in'which the buttbnehble is to be formed, is first stitched armihd, and the opening for. the button afterward out out by a proper instru-- ment. The needle enters the cloth at a point where the inner edge of the button-hole is to be formed. As the needle rises, the looper catches its loop, the clothplate moves laterally,'so as to bring the needle in a position toenter the fabric, at its next descent, out; side, or back of that part of the fabric inwhieh the hole is to be formed. During this lateral movement,

the take-up moves in the same direction as does the cloth.

The needle next enters thefabric outside of the button-hole. 'As it rises, the looper takes its loop, the cloth again moves laterally, in the opposite direction to that in which it first moved; so that the needle, on its next descent, shall again penetrate the fabric inside the button-hole, and, during this lateral movement, the

A spring, K, fig. 2, under thebed-platakeeps the to catch the needle-thread at to the "needle, by the iakemp moves in a direction opposite to the movement of the cloth. By this means, at each upward movement of the needle, the take-up draws off more thread then is required toform the stitch, Whieh surplus thread is given off by the take' up as the needle is about to enter the cloth again, and thuszeompensetes for the vibration of the cloth, and prevents the needle from being dlefieeted from its proper path by the strain on its thread. What reclaim us our invention, and desire to seeure by Letters Patent, isf i V 1 1. The combination, substantially as set forth, bf the vibrating el0th-plate with the vibrating take-up L.

2. The combination, in aisewing-maehine, of the following instrumentelities, viz, an eyepemterl needle, e
