EMBROiDERY- HOOP.

SPECIFICATION forming part of Letters Patent No. 629,847, dated August 1', 1899. plication filed September 24, 1897. Serial No. 652,851. (No model.)

To all whom it may concern:

Be itknown that I, ELIZABETH DooLrr'rLE;

a citizen of the United States of America, residing at Bridgeport, in the county of Fair} field and State of Connecticut, have invented new and useful Improvements inEmbroidcry-Hoops, of which the following is a specification.

My invention relates to means for conveniently compressing the outer hoop against the inner hoop and forreadil y adjusting the coinpressing device.

My invention consists in the construction and arrangement herein pointed out.

In the accompanying drawings, in which like letters of reference indicate like parts, Figure 1 is a perspective View of the outer or adjustable hoop in its opened position arranged outside an inner hoop and with a piece of embroidery held between the hoops. Fig. 2 isa side view with a part in section, illustrating the clamping mechanism. Fig. 3 is an edge View; and Fig. 4 is a view like Fig. 2, but with the device shown in its closed position. v

In detail, a indicates the outer hoop; Ab and c, laterally-projectin g end portions; d,bolt extendingthrough the lateral portions; e,a pivot on which the cam-lever turns and through which the screw passes; f, cam-lever; g, inner ring, and h material.

For the purposes of holding the fabric being operated upon an inner hoop is employed,

which is continuous, the fabric being drawn over it and held in place by being clasped between the inner surfaceof the outer hoop and the outer surface of the inner hoop, and as fabrics vary in thickness it is desirable that the outer hoop be made expansible or adjustable, so that the material may be readily placed in position and the outer hoop then closed, thus grasping it between the twosurfaces and holding it firmly in position.

The binding or outer hoop has its ends projecting laterally, as shown in Figs. 1 and 2,

and a bolt or threaded rod 61 passes from the' lateral projection K? through an elongated opening in the projecting part c. The pivot e is provided with a lateral threaded opening, the thread of which engages the thread upon the bolt d, and the cam-lever f is mounted to turn on the pivot e. s The bolt (1 is fixed to the part b so that it cannot revolve, and when it is desired to adjust the device the cam-lever is carried to a position substantially parallel with the line of the bolt and is rotated, thus carrying the pivot toward or from the bolthead and varying the normal open position of the hoop. \Vhen it is desired to clamp the hoop and grasp the material, it simply becomes necessary to turn the cam-lever f downwardly, so that it will lie snug against the outer surface of the hoop a, where it will remain until raised therefrom for the purpose of releasing the fabric.

It will be observed that the cam-lever is shaped'so as to substantially follow the contour of the hoop against which it lies, and that its outer surface is formed in curved lines extending from a sharp point close to the hoop rearwardly and terminating in curved lines adjacent to the lateral projection c, and

that the projecting end of the bolt d is en-- tirely covered by the cam-lever, so that all projections or points upon which the fabric would be liable to catch or tear are avoided.

Having therefore described my invention, what I claim, and desire to secure by Letters Patent, is-

1. An embroidery-hoophaving laterallyprojecting ends, a threaded boltsecured to one of said projecting ends and projecting through the other, a pivot e, having a lateral threaded opening to engage the thread on the bolt, and a cam-lever f mounted to turn on the pivot e, substantially as shown.

2. The combination in an embroidery-frame of an expansiblc hoop, a cam-lever arranged to carry the ends of the hoop toward each other, a nut pivotally mounted on the camlever, a bolt fixed to one partof the hoop and projecting through the other part and entering said nut, whereby the location of the nut on the bolt may be changed by rotating the cam-lever and nut together substantially ELIZABETH "DooLiTTLn.
