ROLLIN L. RODMAN, OF LOTT, TEXAS.

Specification of Letters Patent.

Patented June 12, 1906.

Application filed April 21,1905. Serial No. 256.737.

To all whom it may concern:

Be it known that I, RoLLIN L. RoDMAN, a citizen of the United States, and a resident of Lott, in the county of Falls and State of Texas, have invented a new and Improved Embroiderin Attachment for Sewing-Machines, of which the following is a full, clear, and exact description.

My invention relates to attachments for sewing-machines, and more particularly for those doing embroidery while the machine is operated by hand.

It consists in the various features and combinations hereinafter described and claimed.

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

Figure 1 is a perspective view of one embodiment of my invention shown in place upon a sewing-machine. Fig. 2 1s an enlarged side elevation of the attachment. Figs. 3 and 4 are horizontal sections on the lines 3 3 and 4 4, respectively, of Fig. 2 {and Fig. 5 is a perspective view of the connector.

I have here illustrated a sewing-machine A havin the usual needle-bar a, carrying the need e b, secured in place by the screw device a. Movable with the needle-bar is the embroidering attachment B, which comprises a support 10, preferably in the form of a flattened tube. This support has at its lower extremity a lateral arm 11, having at its outer end an eye or socket 12, which may be passed over the needle and raised against the lower extremity of the needle-bar. To secure the support in place upon the needlebar, I have provided a connector C, preferably bent from an integral piece of wire and having an angular portion 13 of such form and length as to adapt it to the particular conditions under which the attachment is to be used. This angular portion has at one extremity an eye 14, which may be passed over the needle and brought into contact with the lower side of the socket 12, and an opposite eye 15 to surround some element movable with the needle-bar, conveniently the screw 0. Each of these eyes may be fur nished by one or more convolutions of the w1re.

Movable through the tubular support is a bar. 16, having secured to its lower end a Presser-foot 16*, which may be formed of a strip of metal similar to the bar, it being riv to the work-plate of the eted to one side thereof and then bent gradu-- ally to occu y a plane at right angles to that in which said bar lies, this bringing it arallel machine. n this horizontal portion of the presser-foot is an openin in the form of a slot 1o extending throng the end of the foot farthest from the bar. At the upper extremity of the bar is an arm 17, and between this arm and an extension 18 of the arm 11 lies a spiral spring 19, exerting its tension to draw the presser-foot normally downward, its movement in this direction being limited by the contact of the arm 17 with the top of the support.

The attachment is mounted upon the needle-bar of the machine upon which it is to be used, as has been above described, the form and size of the connector being such as to adapt it to the particular machine or the position in which the attachment is to operate and so that it may move clear of all projecting portions of the machine-head. The silk or other embroidering material to be employed is now passed through the eye of the needle, this being accomplished without the necessity for threading it through the presserfoot, since the slotted opening permits its introduction from the end; The work being placed upon the plate of the machine, it will be seen that when the needle is lowered b turning the balance-wheel by hand it will begin the stitch and at the same time bring the presser-foot into cooperation with the upper face of the work and hold it firmly in place while the stitch is being completed. At this time the movement of the bar through the support against the tension of the spring gives the desired yielding pressure. the needle rises, the resser-foot moves with it, entirely releasing t e work, so that it may be turned or adjusted to the proper position for the next stitch.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a sewing-machine having a neede-bar, of a tubular su port, a lateral arm at the lower end of tl fe support and provided with means for engagin the needle-bar, an extension on the arm, a ar movable within the support, a slotted presser-foot on the bar, an arm on the upper end of the bar, and a spiral s ring connecting the arm and the extension 0 the lateral arm.

2. The combination with a sewing-ma- When chine having a needle-bar, of a tubular support, a lateral arm at the lower end of the support and having an eye for engaging the needle, an extension on the arm, a connector having an eye for engaging the needle beneath the lateral arm, means whereby said connector may be connected with the needlebar, a bar movable Within the support, a slotted Presser-foot on the bar, an arm on the 10 upper end of the bar, and a spiral spring conneeting the arm and the extension of the lat- ROLLINf L.
