CHARLES S. BUOKLIN, OF BALTIMORE, MARYLAND, ASSIGNOR TO JOSEPHINE BUOKLIN AND MARY \V. BUOKLIN, OFSAME PLACE.

EMBROIDERY=HOOR SPECIFICATION forming part of Letters Patent No. 586,947, dated July 20, 1897.

Application filed March 19, 1897.

T all whom, it may concern:

Be it known that I, CHARLES S. BUOKLIN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Embroidery-I-Ioops, of which the following is a specification.

This invention relates to embroidery-hoops.

For the purpose of holding the fabric or :o cloth which is being embroidered by the needle two hoops are commonly employed, one within the other, the fabric being stretched over'the smaller hoop and confined by the larger one. As fabrics vary in thickness it I 5 is found that one pair of hoops which will hold a thin fabric tight enough will not permit the use of a thick fabric. To provide for using fabrics of varying thickness, it has been customary to wrap one of the hoops with a strip of cloth, so as to make the two hoops fit closer. \Vhen thus wrapped, a thin fabric may be used. Now if it was desired to use a thicker fabric the said wrapping would be removed from the hoop, thereby leaving a greater space between the two hoops. 'My invention overcomes this difficulty, and also makes provision for advantages not obtainable by the present devices in use.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a view showing the two hoops with my improvement. Fig. 2 is a top view of same. Figs. 3 and 4t areviews, on a larger scale, of the lateral ends of the binding-hoop.

3 5 Fig. 5 is a view, also on a larger scale, of the bolt.

The smaller hoop a is shown in the drawings in solid black. This inside hoop is the holding-hoop, which is endless and differs in this respect from the larger hoop b, which is split, so as to admit of expansion and contraction.

The binding-hoop Z) surrounds the holdinghoop a, and has two ends which project later- 5 ally. One end 0 has a round hole e and the other end d has a rectangular or oblong hole f. A screw-threaded bolt g has a flattened head g',which fits in and is movable through the oblong hole f in one end, while the round screwthreaded part of the bolt fits in the hole e of the other end. A cam-lever h is pivoted to inner hoop.

Serial No. 628,241. (No model.)

the'flattened head of the bolt, and'the cam end h of said lever is in position to bear against the lateral end d of the outer split hoop when the free end of said lever is turned toward the hoop. A thumb-nuti is on the screw-threaded part of the bolt in position to bear against the other lateral end 0 of the split hoop.

The function of the thumb-nut 2' is to effeet the preliminary tightening of the outer split hoop while the cam-lever h is turned to its released position, and the function of the cam-lever is to quickly effect the final tightening of the split hoop.

In operation if we suppose the outer split hoop Z) to be expanded and removed from the inner hoop a the parts are in position to permit the fabric or cloth to be adjusted over the inner hoop. The outer hoop I) while in the expanded condition may then be pressed over the said fabric or cloth and around the \Vhen the fabric has been properl y smoothed out, the thumb-nut i can easily be turned to effect the preliminary tightening of the binding-hoop b, and then the camlcver can be moved to quickly effect the final tightening. hen it is desired to shift the fabric or cloth, the cam-lever must be moved to relax the binding-hoop. This relaxing is a quick operation, much quicker than that of turning a nut. Besides being quicker in action the cam-lever enables the split hoop to be drawn tighter than the little thumb-nut operated merely by the fingers of the hand. When the cam-lever draws the split ends 0 d, the flattened head g of the bolt moves through the oblong hole f in the lateral end (1. A nut is is on the screw-threaded part between the two lateral ends of the split hoop. Normally this nut does not bear against either of the lateral ends of the split hoop and allows the bolt freedom to move. It serves to prevent the bolt and cam-lever from accidental detachment from the lateral end 61 when the 5 thumb-nut i has been removed, and when the parts are loosened to adjust the fabric it prevents thelateral end getting on the threaded part.

Having thus described my invention, what I claim is A- pair of embroidery-hoops having in combination an inner hoop; a split binding-hoop surrounding the inner hoop and having two lateral projecting ends one of which has a bolt-hole, e, and the other an oblong hole, f,- a screw threaded bolt having a flattened head, the threaded end being through the said bolt-hole and the head through the said oblong hole in which it is movable; a thumbnut on the threaded end of the bolt; a camlever pivoted to the flattened head of the 10 bolt; and a not on the bolt between the two lateral hoop ends.

In testimony whereof I allix my signature in the presence of two witnesses.
