Specification of Letters Patent.

' Patented May 12, 1908.

Application filed January 27, 1908. Serial No. 412,774.

'Be it known that I, FREDERICKE. KOHLER, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented anew and useful Improve- ,ment in Embroidery-Hoops, of which the following is a specification.

The invention relates to a of two rings, one adapted to telesco e loosely outside the other for the purpose ofoldin a for the rings are made entirely out of wood or other relatively hard and smoothfmaterial, and no means are provided for a change in the diameter of either ring, such hoop is' not well adapted to hold fabrics of different thick nesses and consistencies; and for the pur ose of increasing the resilience and friction o the holding surfaces, a rubber band has been wrapped around or applied longitudinally along a flat holding sur ace on one or both of the rings, and a flexible fibrous band or cord .hasalso been partially countersunk in the same. these a pliances. When a rubber band is wrappe and light condition so desirable in a hoopof this character, and the band is apt to wear off at the edges of the ring and requires frequent renewal. When a band of soft rubber isfapplied longitudinally along the flat surface of the rin the edges become-loosened from the wood b use and stretch or foldout of place, and the fio'op soon loses its efficiency. An'd finally, when a resilient frictional band or cord ispartially countersunk in the face of the ring, the hoop soon becomes inefficient by reason of the ordinary wear anduse which either abrades the protruding portion of the countersunk materlal down to the plane of the hard body of the ring, or overcomes the resilient qualities of the frictional material and com resses it entirelyinto the counter sink in t e ring; and furthermore, when. a

band is countersunk, unless and until the protruding edges of the same are worn off by the abrasion of use, they are apt to be loosened and either-stretched or folded out of place like the edges of a band which is merely laid on a flat surface.

The. object of the present invention is to overcome the ob'ections whichhave been noted as pertaining to the devices whichhave been employed to increase the resilience hoop composed Serious objections pertain to .eachjoft around a ring, it rnakes the hoopquite cumbersome and takes away the neat and friction of the, holding surfaces of the rin 's,andithis object isattained by forming I at east one rirzlg, preferably the inner ring,

with a flat mid .ortion located in a plane parallel with the olding faceof the other ring, and by diverging as by bev'eling or curving the side portions of-"the holdin face i of the one-ringaway from the adjacent old ing face of the other ring; and then by gluing or otherwise securely attaching a resilient frictional band, preferably of somewhat soft and pliable leather or felt on the middle flat 'ortion of the one ring, with the sides of the band extended over and across the diver ing faces to' or near the edges thereof; asgi ustrated in-the accompanying drawing, in.

which- I Figure 1" is' a perspective view of the improved inner ring, showing the resilient frictional band applied thereon;-Fig. 2, an axial-' sectional view, showing the fabric laid over the inner ring and the outer ring in position for telesco ing overthe same; Fig, 3, a similar view, s owing. the outer ring telescoped over the inner. ring'with the fabric stretched and held taut over the inner ring; Fig. 4, an enlarged sectional view, showin beveleddiverging side portions on the hoding face of theinner ring; and Fig. 5, an enlarged sectional view,- showing curved diverging side portions on the holding face of the inner ring. Similar numerals refer to similar parts throughout the drawing; v

The inner ring '1 or 1 ismade of wood,

terial, and is' formed with the flatmiddle'portion 2 or 2 located in a plane parallel with the holding'face 3 of the outer ring {ll-when the same is telescoped around the inner ring. The side portions 5 or 5 are either beveled or curved from the flat middle portion to the side edges .of the ring, so as to diverge away from the adjacent holding face of the outer ring. o The resilient frictional'band 6 or 6 is glued orotherwise attached on the holding .face of the inner ring, and is of such width as to entirely cover the middle flat portion thereof and to have its side portions extended over and across the diverging portions of the holding face of the ring, preferably to 'or'near the side edges thereof. The outer ring 4 is likewise made of wood or other suitable material, and-as shown, is preferably formed with its inner face 3 smooth or flat, excepting only'as the corners 7 maybe slightly chamfered or rounded; and when the fabric 8 is placed over'the inner ring, as shown imFig. 2, the outer ring is placed over and then forced downward around the inner ring, which stretches and holds the fabric taut over the inner ring. The resilience and friction ofthe band on the inner ring serves to give a resistingpressure against the outer ring, and to prevent a slipping of the fabric as against an ordinary. strain, but nevertheless permits the fabric to be forcefully pulled and adjusted in any desired position.

It is evident that by reason of the side portions of the resilient frictional band being extended u on the diverging portions of the face of t e inner ring, the diameter of the edges of the band is so much less than the diameter of the holding face of the outer ring, that the edges of the outer ring will strike the rounded or cone-shaped side of the face of the band which is resented to the outer ring,

l and will be guide thereby to the fiat middle extreme edges of the band.

of striking the It is also evident that the. band will continue to be efiective until it is worn entirely off the flat portion of the ring, between the diverging side ortions thereof, for there is no countersink 111 the ring into which the leather can be com ress ed.

Tffe edges, of the resilient frictional band are preferably arranged to terminate a slight distance inside the edges of the inner ring, and these edges are thusprotected by the etfiges of the ring from the wear and abrasion 0 use.

The advantages of the articular form of construction as described lierein are best at tained by using a comparatively thin resilient frictional band, or one having comparatively thin edge portions, so that the shoulder formed by the same on the face of the ring is not sufficient to invite serious abrasion or injurious contact. By using a portion of the band, instead band of this character no special provision need be madefor rotecting the edges of the band other than oy diverging the side porsa7,eoa

tions of the holding face of the ring to which the side portions of the bandare attached, from the adjacent holding face of the opposing ring.

It will be understood that the form and shape of the holding face of the inner ring can be somewhat varied without departing from the general idea of the invention, but it is preferable to make the flat middle portion of considerable width so as to resent a broad holding face in a plane paralle with the holding face of the outer ring; and it is necessary to have the side portions of the resilient frictional band extended over and across the diverging portions. of the holding face of the inner ring, far enough to form an appreciable rounded or cone-shaped face toreceive and guide the contact of the edges of the outer ring when the same is being telescoped over the inner ring, and to reduce the diameter of the edges of the band so that the outer ring will not injuriously strike the same. And it will also be understood that the invention is not limited in see c to the use of leather or felt as the materia for the resilient frictional band, nor to the application of'the invention to hoops having rings of unvarying circumferences.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

An embroidery hoop comprising two rings one adapted to telescope Within the other, the holding face of 'one ring having a flat middle portion presented to the opposing face of the other. ring and side portions diverging therefrom and extending from said flat middle portion to the side edges of the one ring, and a resilient frictional band at-,

tached on the holding face of the one ring and extending upon the diverging sideportions thereof.
