WALKER SALES COMPANY, A CORPORATION OF NEW YORK.

EMBROIDERY-FRAME.

To all whom it may concern:

Be it known that I, HERBERT AURELIUS AUSTIN, a citizen of the United States, and a resident of the cityof Boston, county of Suffolk, and Commonwealth of lvlassachw setts, have invented certain new and useful Improvements in Embroidery-Frames, set forth in the following.specification.

My invention relates toimprovements in embroidery frames for holding fabric while being worked upon and more particularly to embroidery framescomprising a pair of hoops, one of which may beexpanded or contracted, as the case may be, to cause the outer hoop to envelop the inner hoop and the fabric, thereby to clamp the work therebetween. In carrying out this invention, it is preferredto provide the necessary adjustment by splitting the inner hoop and making it expansible to clamp the work.

It is, therefore, an obj eet of this invention to provide a simple yet readily manipulated expanding means or adjustment.

A further object is to provide practical means for causing the limited relative move ment of the ends of said split hoop to provide for the desired adjustment, but which will effectually prevent the said ends from becoming widely separated or out of ahnement.

Another object is to make possible the manipulation of their adjustment with quickness and despatch.

Other objects will be in part obvious and in part pointed out hereinafter.

This invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated in the following claim.

In the accompanying drawings wherein are shown one of the possible embodiments of my invention,Figure 1 is a sectional view of a pair of embroidery hoops, the inner one of which is provided with expanding means, made in accordance with this invention,-Fig. 2 is an inside View of a portion of the hoop and expanding means.

Similar reference characters refer to similar parts throughout the drawings and specifications.

Referring to the drawings, 1 and 2 desig Specification of Letters Patent.

ment 6, secured adjacent the other end of said hoop in a manner similar to the said member 3. The inner end of the abutment member 6 is extended beyond the aperture ,5 and is slightly curved, asat 7, for a purpose to be hereinafter described. A knurled nut 8 carried by the bolt 4 serves either to expand the hoop 1 by slightly separating the ends thereof, or to hold the said ends apart when they have been separated in the manner to be described. After the parts have been assembled in the relation shown, the end of the bolt 4 is upset, by swaging or in other suitable ways, so as to provide thereon a knob-like stop or anti-disassembling means 9. This anti-disassembling means forms an important part of the present invention, for it has been found in practice that one of the greatest drawbacks to the extended, if not universal, use of adjustable embroidery frames of this character resides in the fact that the parts, where the bolt and nut principle have been employed,

have become easily detached, either carelessly by the user or mischievously by children, with the result, in either case, that parts have become lost or, at least, considerable annoyance has been caused to the user through having to reassemble the said parts.

The stop makes it practically possible to use the construction shown, which is notable for the fact that the nut need not be used to separate the ends of the hoop, whiclrmay preferably be accomplished by pinching between the thumb and forefinger of one hand the said stop and the hereinbefore mentioned curved extension 7 of the abutment 6. It will be evident at a glance that this is a great advantage, as it permits the user to adjust the fabric carefully between the hoops and, by resistingly pressing the said stop and extension 7 together, to hold the same, with any desired pressure, until the cloth or fabric is in the position best adapted for working when the nut 8 may be spun to travel along the threaded member in order to maintain the adjustment.

It will be obvious that the principles of this invention are applicable to embroidery frames wherein the outer ring is the adj 11stable one. In such usage the nut would, of curse,be disposed upon the opposite side of the abutment member and the whole device would be fastened to the outer side of the outer hoop.

As many changes could be made in the above construction and many apparently widely difiierent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the above drawings shall be interpreted as illustrative and not in a limiting sense.

What I claim as new and desire to secure by Letters Patent of the United States is In an embroidery hoop in combination, a split ring; an abutment attached to one end of said ring and having an aperture; a threaded member attached to the opposite end of said ring and passing freely through the'aperture in said abutment; a nut engaging the threads of said threaded member and free to spin and travel thereon into and out of engagement with said abutment, whereby said nut 1s adapted to move said abutment in a single direction only and whereby said abutment may be moved manually independently of said nut; an extension on said abutment adapted to provide a finger hold; and an enlarged stop on the end of said threaded member tomaintain said threaded -member, said nut and said abutment permanently assembled.

In witness whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
