EMBROIDERY-HOOP.

To all 10h-0m t may concern.'

Be it known that I, L'Ewis Giens, a citizen of the United States, residing in Canton, Chio, have invented certain Improvements in Einbroidery-l-loops, of which the following is a specification.

My invention relates to that class of em broidery hoops in which the outer hoop is expansible and contractible in order to permit of the ready application, removal or readjustment of the material for whose conlinement the hoops are intended, one object of my invention being to insure the hrm retention of such material, while permitting ready adjustment of the same.

Another object is to so construct the expansible and contractible hoop as to render unnecessary the overlapping of the ends of the same and the consequent `tapering or feather edging of one of said ends in order to avoid an abrupt shoulder on the inner face of the hoop, my improved hoop having squared ends which, if desired, may be caused to abut when the hoop is contracted.

A further object of my invention'is to laterally retain the ends of the hoop independently of the adjusting device, the only function of the latter being to spread or contract the hoop, and a still further object is to provide an adjusting device which, while lightin weight, is strong and compact, and will securely retain the hoop when the latter is contracted.

These objects I attain in theV manner hereinafter set forth, reference being had to the accompanying drawings, in which- Figure 1 is a perspective view of a pair of embroidery hoops, the outer of which is equipped with an expanding and contracting device in accordance with my invention; Fig. 2 is a perspectivev view of the inner faces of the meeting ends of the outer hoop showing the same in the expanded condition; Fig. 3 is an enlarged horizontal section showing the outer hoop in the contractedcondition; Fig. 4 is a similar view with the hoop in the expanded condition; Fig. 5 is a transverse section on the line a-f.z, Fig. 3; Fig. 6 is a transverse section on the line 5 5, Fig. 4; Fig. 7 is a perspective view of one end of the hoop;l

Fig. 8 is a perspectve view of the other end of the hoop; Fig. 9 is a perspective view Specieation of Letters Patent.

of the adjusting device employed in conneet-ion with the opposite ends of the hoop; Fig. lO is a view similar to Fig. 3, but illus trating a modification of my invention, and Fig. 1l is a sectional view illustrating another modification.

ln Fig. 1 of the drawing, l represents the inner hoop and 2 the outer hoop, said hoops being composed of wood, vulcanized fiber,

or other available material, and the inner hoop being a plain or continuous hoop preferablyl provided, on its outer face, with a facing or covering 3 of felt or textile material for the purpose of insuring an elastic grip upon the material which is to be clamped between the two hoops, although, if desired, this layer of felt or textile material may be applied to the inner face of the outer hoop or both hoops ma)7 be thus provided, if desired. The outer hoop 2 is split in order that it may be expanded to permit of ready introduction between the hoops of the material to be confined thereby and then contracted upon said material in order to effect the secure clamping of the same between the hoops.

When the felt or textile facing is employed in connection with either or both of a pair of hoops, one of which is expansible, the material to be held by the hoops is, when the expansible hoop is contracted, confined more firmly in position than when both hoops are continuous, while when the hoop is expanded, free movement of the material is permitted and adjustment of the same in respect to the hoops can be readily effected. The meeting ends of the outer hoop are square, that is to say they are at a right angle to the inner and outer faces of the hoop, in order to preserve the full strength of the material up tothe end of the hoop, whereas if one end of the hoop overlaps the other, the inner overlapping end must be tapered or feather edged in order to prevent the formation of an abrupt shoulder on the inner face of the hoop, thereby not only weakening one end of the hoop but forming an objectionable thin edge on the same which is liable to be broken in use.

The meeting ends of the hoop may also be square in respect to the top and bottom edges of the same, although it is preferable V vide a diagonal joint as shown in Fig. 2,

and thereby prevent the formation in the outer hoop, when the same is expanded, of a vertical gap into which the material to be confined between the hoops might enter and thus prevent the proper contraction of said outer hoop.

Each end of the hoop is provided with a metallic tip plate, that at one end of the hoop being represented at 4 and that at the other end of the hoop at 5, these tip plates being secured to the wood or other material of which the hoop is composed by means of pins, rivets, or other suitable fastenings 6. The tip plate 4 has a thickened end 7 in which is formed a slot 9, elongated vertically, and the tip plate y5 has a pocket 10, formed by bending or folding over toward each other wings 11 forming a part of said tip plate 5 as shown in Fig. 8.

The thickened end 7 of the plate 4 is fitted to the pocket 10, but can slide freely therein, the ends of the hoop being thereby retained laterally, so that, irrespective of its function of expansion and contraction, the hoop possesses all of the qualities of a solid hoop. Mounted on the pocket 10 of the tip plate 5 is a recessed disk 12 provided, by preference, with a knurled or milled edge whereby it can be readily turned by the fingers, this disk having a hollow hub 13 which passes through the back member of the pocket 10 and is expanded in an opening therein so as to laterally confine the disk 12 to the pocket. Secured to or formed integral with the disk 12, or its hub 13, are disks 14 and 15, the disk 14 being concentric with the axis of the hub 13 and adapted to turn freely in an opening 16 in the outer member of the pocket 10 and the disk 15 being eccentric in respect to the axis of the hub 13 and adapted to the slot 9 in the thickened head 7 of t-he tip plate 4, as shown in Figs. 3, 4, 5 and 6.

When the disk 12 is turned so that the eccentric disk 15 occupies the position shown in Figs. 3 and 5, the hoop 2 will be fully contracted and when the parts are adjusted to the position shown in Figs. 4 and 6, the hoop 2 will be fully expanded. When in either of t-hese extreme positions the eccentric disk 15 is seated in the bottom of the slot 9, consequently, when the disk 12 is turned so as to open the hoop, its movement is arrested when the hoop is fully exi panded, and in like manner, when t-he disk is turned so as to close the hoop, its movement is arrested when the hoop is fully closed. By this means accidental spreading of the hoop after it has once been contracted, or accidental tightening of the hoop after it has once been expanded, is prevented, as such change in the condition of the hoop requires a reversal in the direction of movement of the operating disk 12 and said reversal implies attention on the part of t-he operator, whereas, if the disk 12 was free to make a complete turn, the hoop would be liable to accidental spreading after being contracted or to accidental contraction after being expanded.

As shown in Figs. 1, 2 and 8, the tip plates 4 and 5 are applied to the outer face of the hoop but they can, if desired, be applied to the innerface, an instance of this construe# tion being shown in Fig. 10, and the pivot hub of the disk 12, instead of being integral therewith, may be a separate pin secured to the disk as shown at 13a in Fig. 10 or said pivot hub may be in the form of an eyelet as shown at 13h in Fig. 11, the disks 12, 14 and 15 being secured together and free to turn on this eyelet or these disks being secured to the eyelet which is free to turn in its bearing in the Vinner member of the pocket 10.
