UNITED STATES AARON WALDMAN, OF NEW YORK, N.

EMBROIDERY FRAME.

Application filed October 21, 1922. Serial No. 596,112.-

To all whom it may concern:

Be it known that I, AARON WALDMAN, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented new and useful Improvements in Embroidery Frames, of which the following is a specification. 1

This invention relates to embroidery frames.

An object of the invention is to simplify the construction of frames of this character and establish an arrangement of co-acting parts which will facilitate the operation of stretching the fabric upon the frame and permit this operation'to be carried on by a single operator Another object of the invention is to provide a frame of this character employing novel means for slidably relating the stretching bars with respect to each other and for uniformly securing the bars in positions of adjustment while holding the same against the usual separation.

l/Vith these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claim, and are illustrated in the accompanying drawing, in which:

Figure 1 is a plan view of the frame.

Figure 2 is an edge view thereof.

Figure 3 is a section taken on line 83 of Figure 2.

Figure 4 is a section taken on line t4lof Figure 2.

Figure 5 is a section taken on line 55 of Figure 3.

Figure 6 is a perspective view of the coupling.

In carrying the invention into practice use is made of mating top bars 6, 6 and similar mating lower bars 7, 7, each provided on its inner edge with a strip of attaching fabric 8 adapted to be pinned or otherwise suitably secured to the stretched fabric 9 as shown in Figure 1. I do not wish to limit myself to the manner in which the fabric 9 is secured to the strips 8 but find pins 10 adequate for this purpose.

Mounted upon the lower bars 7, 7 are coupling devices 11, one provided at each corner of the complete frame as shown in Figure 1. Each of these devices consists of a lower rectangular sleeve 12 and an upper U-shaped guide 13. The rectangular sleeves 12 are freely slidable upon the bars 7. The guides 13 act as stirrups to slidably accommodate the upper bars 6 of the frame.

The said upper bars 6 are grooved longitudinally at 14 along their outer edges. These grooves are provided with ratchet teeth 15 adapted to co-act with swinging dogs 16 on the guides 13. The opposite or inner edges of the bars 6 are engaged by leaf springs 17 and as illustrated the said guides are equipped with retaining lugs 17 which co-act with the springs 17 and the grooves 14 so as to hold the upper bars 6 against casual disengagement from the aforesaid guides 18. The dogs 16 are adapted to be released from the ratchet teeth by swinging actuating members 18 mounted on the guides 13 as clearly shown in Figures 3 and'6 of the drawing. The tail portions 19 of the dogs 16 are engaged by springs 20 which act to normally hold the dogs 16 in looking relation to the ratchet teeth 15. By simply pressing upon the actuating members 18 the dogs 16 may be instantly released from the ratchet teeth so as to permit frame bars 6 to be moved or adjusted to the mating bars 7. The actuating members 18 are provided with retaining fingers 21' which overlie the bar 6 as shown in Figure 1. The purpose of this arrangement is to further insure accidental derangement of said bars 6 from the saddle like guides 13.

The sleeves 12 carry spring pressed dogs 22 engageable with ratchet surfaces 23 arranged upon the outer faces of the bar 7. These dogs operate to hold the said bars 7 in their extended positions for adjustment with respect to the mating bars 6. The tail portions 24 of the dogs 22 are related with respect to the actuating members 18 whereby these parts are capable of being actuated simultaneously by one hand. Incident to this arrangement the respective bars 6 and 7 of the frame may be brought to positions of adjustment by a single operator.

From the construction described it'will be seen that the frame bars can be expeditiously adjusted; that the fabric to be embroidered or stretched can be quickly and securely applied to the frame; that the entire structure which is simple, strong and durable; that it consists of few operating parts, and that the several par can be knockedtdown or readily .set up as the occasion .Iequired;

While I have described What I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied Without in any way departing from the spirit of my invention, and

1 therefore do not limit myself to the exact details of construction herein set forth nor to anything ,less' than the whole of m invention limited only by the appended e aim. What is claimed as new is An embroidery frame including a plurality of stretching bars, ratchet members secured-to the outer faces of said bars and arranged in longitudinal grooves formed therein, coupling devices formed in corner of the frame for retaining the bars in operative position or frame formation, a lower rectan ular sleeve forming a portion of each coup ing device Ind adapted to receive one of said bars for slidable movement therein, a substantially U-shaped guide formed on the sleeve of each device and arranged at right angles thereto for receiving the remalning bars of the frame, dogs passing through the outer side wallof each sleeve and guide respectively for operative engagement with the teeth of the bars, slotted spring pressed manipulating meminthe guides and sleeves respectively. 7

In testimony whereof I have affixed my signature.

V AARON WALDMAN.
