Angeles, in the county of Los Angeles and State of California, have invented a new and' 'useful Needle-Plate for Sewin Machines, of

which the following is a speci cation.

An objectof this invention is to provide for sewing-machines a superior attachment of that class of devices whereby such machine can be made efficient for making embroidery, Spanish drawn-work, and Battenberg work, and for darning broken or worn fabrics.

be embodied in differ'- I shall illustrate the `same in two, forms which are capable of use on rotary sewing-machines, although I do not pro- 'ose to limit the inventionto lany specific orm or construction in which it may be embodied. Y

The invention com rises a sewing-machine needlecess an( with a tubular thread-guide extending downwardly through and surrounded by ,'aecess and arranged coaxially with relation to and forming an extension of the needlehole of the plate; said plate being constructedU and adaptedto be connected with 4the bedplate of a sewing-machine and to formabove said bed-plate a protuberance having a sloprim. Said protuberance may-be formedinvention.

Fig. 2 is a like view of a machine provided with the improvement in a form of vembodiment more especially ada ted for silk embroidery. 31s a longitu( inal section on line :eL-x, 1 4 and 5, of the" form shown in Fig. y1'. ig. 4 is a section taken at right angles to the section in Fig. 3, on line x, Figs. 3 and 5. Fig. 5 is a bottom view of the form shown in Figs. 1, 3 and 4. Fig. 6 is a section on line rv, Figs. 7 and 8, of the plate' shown in Fig. 2. Fig. 7 is a section on line xl, Figs. 6 and 8. Fig. 8 is a plan view of the plate shown in Fig.2.

.This newly invented needle plate comprises an upwardly (proectin plate 1 having a apte to support the late provide underneath with a ite-' embroidery or other material, not shown, to be o erated upon, and is provided with a need e-hole 3 and with a recess 4 surrounding a downwardly-extending tubular threadguide 5. Said recess 4 is of appropriate dimensions to chamber that portion of the feed 6 of the sewing-machine which usually projects above the surface of the sewing-machine bedlate 7. Said vtubular thread- `guide exten( s downward through the usual slot 8 in the feed so thatno obstruction is offered to the operation'of the feed. y

In practice, when it is desired to use the 'sewing-machine for doing embroidery work, Battenberg work, or the like, the presser-foot and the needle-plate, not.sliown, Will be first removed from the machine. Then the newly-invented needlelate will be placed in position with the beve ed rim upward and the recess in osition to receive the feed, While the tubu ar'thread-guide extends down `throu h the slotted feed. The needle-plate will tien be secured in lace by suitable means, as screws 9 inserte( through holes in the needle-plate.

'I he purposeof the tubular thread-guide 5 is to carry the thread down below the teeth or points of the feed 6 so that there is no 'danger of the thread loops being caught b'y the teeth or points of the feed, and so as to insure lthat the loop will 4he caught by thev under thread. In practical use, by providing the plate constructed as-set forth, thel operator can move the embroidery or other fancy Work freely without any liability of` catching; and the Work -is greatly facilitated as compared with the usecf former devicesin which the protuherance `formed by the plate has been oi' an angular character.
