EMBROIDERY-FRAME.

Specification of Letters Patent.

Patented Nov. 10, 1914.

Application filed May 21, 1913. Serial No. 768,949.

To all whom it may concern Be it known that I, ADOLF ROMINGER, a citizen of the United States of America, residing in Guttenberg, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Embroidery-Frames, of which the following is a specification.

This invention relates to certain improvements in the embroidery-frame for which Letters Patent were-granted to me heretofore on February 28, 1911, No. 985,453, whereby the embroidery-frame can not only be used for embroidering ornaments, initial letters, etc., in the corners of handkerchiefs and other articles, but also for embroidering ornamental designs on one or more sides of the articles; and for this purpose the invention consists of an embroideryframe which comprises an upper and a lower frame-piece, a plurality of parallel channelbars' attached to said frame-pieces, clamping bars covered with yielding material vulcanized on and anchored to said bars, said clamping bars being detachably pivoted to the upper ends of the channel-bars, means on the lower frame-piece for engaging the clamping bars for holding them in the channel-bars, and clamping clips attached to the underside of the upper frame-piece between said channel-bars flush with the face" of the same.

The invention consists further in certain details of construction'of the channel-bars in the claims.

In the accompanying drawings, Figure 1 represents a front-elevation of my improved embroidery-frame, Fig. 2 is a horizontal section on line'2-2, Fig. 1, Fig. 3 is a vertical transverse section on line 3-3, Fig. 1, Fig. 4 is a front-view of a part of the upper frame-piece of the embroidery-frame and the clamping clip for the articles to be embroidered, drawn on a larger scale, Fig. 5 is a vertical transverse section on line 5-5, Fig. 4, and Fig. 6 is a horizontal section on line 6-6, Fig. 4, drawn on a still larger scale.

Similar letters of reference indicate corresponding parts throughout the different figures of the drawings. 1

Referring to the drawings, a and a represent respectively the upper and" lower frame-pieces, b the channel-bars and c the Swiss embroidering-machines in which a number of handkerchiefs or other articles are to be embroidered at the same time. The embroidery frame corresponds in length with the embroidery-machine with which it is to be used. Into recesses in the upper and lower frame-pieces a and a are attached the vertical channel-bars b, which are made 'U-shaped in cross-section and reinforced at their sidewalls by doubling over the sheetmetal blanks from which the same are made, as shown at b in Fig. 6. This strengthening of the channel-bars is necessary for the reason that they are made of greater length than the channel-bars in embroidery-frames of a similar nature which were used heretofore, so that not only ornaments, mon0- grams, initial letters, etc., can be embroidered in the corners of the handkerchiefs or other articles, but also ornaments of greater length into the sides ofthe articles, as for this sort of work the ordinary U-shaped channel-bars would not be long andstrong enough for supporting the tightly stretched portions of the articles. The channel-bars b are extended above the frame-pieces at their upper ends, so that their side-walls approach each other and permit the pivoting of the upper ends of the clamping bars or equivalentengaging means 0 to the upper ends of the channel-bars, which is accomplished by means of a screw-pivot at having a head (1 at one end and a screw-nut d applied to the threaded shank of the same, as shown in Figs. 1 and 4. The screw-pivot connection of the clamping bars and channel-bars permits the convenient detaching of the clamping bars for repairs or renewal as required. The lower ends of the clamping bars 0 are slightly and gradually curved forward or offset in forward direction so as to project somewhat beyond the lower portions of the side-walls of the channel-bars b for permitting thereby the tight holding of the clamping bars in the channel-bars by means of retaining catches e, which are pivoted to the lower frame-piece a as shown in Fig. 1, and which first grip above the offset portion of the clamping bars 0, and then gradually tighten their grip as they are further revolved, the offset portions of the clamping bars a acting as wedges. The lower ends c of the clamping bars 0 are extended below the frame-piece a and twisted into a position at right angles to the main-portion of clamping bars of an embroidery-frame for I the clamping bars, so that the projecting ends 0 can be used as. handles in removing the clamping bars from the channel-bars, as shown in dotted lines in Fig. 3, or replacing them into the channel-bars afterthe articles which are to be embroidered have been placed in position between the channel and clamping bars.

The clamping bars 0 are provided at the sides and inner edge with a covering f of U-shaped cross-section, made of soft rubber or other elastic material. This covering 7 is preferably vulcanized onto the clamping bars so that it adheres firmly thereto. The outer or front edge of the clamping bar is left uncovered, but the covering f is further secured to the clamping bars by providing holes 0 at suitable distances from each other in the same through which the rubber covering f is passed and anchored for securing the covering in a still more reliable and secure manner to the clamping bars. Ihis arrangement is superior to the sleeve-shaped elastic coverings which were heretofore used, and which had the disadvantage that their front-edges projected beyond the edges of the channel-bars and exerted a brake action on the shuttles as they are passed through the embroidcry-machine. This is entirely avoided by leaving the outer edge or face of the clamping bars uncovered, as shown in Fig. 6, so that no part of the same can project bevond the outer faces of the glamping bars and the edges of the-tchannelars.

The corners or sides of the articles to be embroidered are held in position by clamping clips f/ which, instead of being arranged on the faces of the upper frame-piece, are located below the same at points between the channelbars, as shown in Fig. 1. They consist of an an ular bracket that is attached to the underside of the upper framepiece a and provided at its lower edge with a forwardly-extending flange 9 which flange is located within the plane of the faces of the frame-pieces. On the flange 7 is placed a transverse detachable key 9 which is held in position after the corner or side-portion of the article to be embroidered is placed in position between the flange and key, and held thereon by means of a latch A which is pivoted at its upper end to the upper portion of the angular bracket (7 as shown in Figs. 4 and 5, so as to securely hold the article to be embroidered in on the clip.

The articles to be embroidered are placed into the embroidery-frame in the usual manner by being stretched by means of the channel-bars and clamping bars at their sides and clips at their corners, as shown at the left hand side of Fig. 1, or with their end-portions secured by the clips and by their side-portions between the channel-bars and clamping bars When a longer ornament is to be embroidered, as shown at.the righthand side of Fig. 1. The practical application of the embroidery-frame is thereby considerably enlarged and not confined only to ornaments in the corners, but also capable of use for embroideringthe sides of articles. Furthermore, by the stronger construction and greater length of the channel-bars and clamping bars and the vulcanizing of the elastic material to the clamping bars, these parts are stronger and more permanent and not subjected to'injury or wear, as no part of the same projects beyond the plane of the faces of the frame-pieces. For this reason the clamping clips are arranged in such a manner as not to pro ect beyond the face of the upper frame-piece, and the entire embroidery-frame thereby rendered more useful for the users of Swiss embroidery-machine's known as shuttle machines.

I claim:

1. An embroidery-frame, comprising upper and lower frame-pieces, upright channel-bars attached to said frame-pieces, 31

pivoted clamping bars pivoted to the upper ends of the channel-bars and inserted into the same, U-shaped elastic coverings extending around the sides and inner edge of the clamping bars, means for locking the lower ends of the channel-bars to the lower framepiece, and clamping clips attached to the underside of the upper frame-piece between said channel-bars.
