EMBROlDERlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 552,035, dated December 24, 1895.

Application filed December 11, 1894. Serial No. 531,529. (No model.)

To all whom it may concern: I

Be it known that I, ALOIS BOEHI, a citizen of Switzerland, at present residing in Newark, in the county of Essex and State of New J ersey, have invented a new and Improved Embroidering-Wfachine, of which the following is a full, clear, andeXact description.

The object of the invention is to provide a new and improved embroideringmachine, more especially designed for elaborately embroidering the corners of handkerchiefs at a comparatively low expense.

The invention consists in the novel arrangement and combination of parts that will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the workcarrying frame. Fig. 2 is a sectional plan view of the same on the line 2 2 of Fig. 1, and also showing the needle-carriage. Fig. 3 is an enlarged transverse section of the same on the line 3 3 of Fig. 2, and Fig. 4c is an enlarged face view of an embroidered corner of a hand kerchief.

In machines for embroidering the corners of handkerchiefs as heretofore practiced, each handkerchief corner was operated on by a single needle, and the tambour-frame carrying the handkerchief was moved by the use of the pantograph according to the pattern, so that the corner of each handkerchief received as many stitches as the pattern indicated. In practice the operator in charge of such an embroidering-machine is paid according to the number of stitches in the patternthat is, on a design having five hundred stitches double the amount is paid as for a design having two hundred and fifty stitches.

By the arrangement presently to be described the operator in charge actuates the pantograph on the pattern in the usual manner during the time the machine is in operation, but double the number of stitches are produced in the corner of each handkerchief in the frame than are contained in the pattern, and at the same time a unitary design is produced which is more elaborate than the pattern. In order to accomplish this result, I provide the operating-needle carriage A of folded u in a 'rooved ost F and its corner to be operated on is stretched to the next post and clamped in the usual manner by the bars E, as shown in the drawings. It will therefore be understood that the clamping-bars E and the grooved posts F constitute as many individual fabric-holders as the number of handkerchiefs it is desired to hold in the tamhour-frame F.

The work-frame F is connected with the pantograph under the control of the operator and manipulated according to the pattern. As the pantograph and pattern are the same as those of the ordinary embroidery-machine, it is not deemed necessary to illustrate and describe the same in detail. It suffices to say that the pattern represents but approximately onehalf of the design finally produced in the corner D of the handkerchief in the frame F. The needles 0 and O are spaced apart according to the design to be produced in the corner of the handkerchief, so that the final result is a unitary design, and not a mere duplication of the pattern. In order to produce this unitary design, it is necessary that some of the stitches of one of the needles be covered by the stitches of the other needle. For instance, in the design shown in Fig. 4, the needles 0 and O produce with their threads the design parts D and D respectively, and

the stem D" of the design part D has its lower portion hidden underneath the larger flower D of the design part D produced by the needle 0. Hence this design shown in Fig. i is not a mere duplication of the pattern, but forms a unitary design.

It is understood that in starting the .ma chine to produce this design the lower ends of the fiower-stems D D" of the design parts 1) D respectively, are first produced, then the side twigs and finally the large flowers D D every design can thus be used or produced by this arrangement in the handkerchief corner, but a skillful designer can readily produce a large number of varied designs capable of being produced by the two needles.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent The combination, with the tambour frame having a series of individual holders for the articles to be embroidered, of areciprocating needle carriage provided with a set of two needles arranged to move in the space between each two holders, the sets of needles being spaced from each other at a distance corresponding to the distance between the indivi dual work holders, substantially as described.
