FABRIC FRAME FOR SEVERAL-NEEDLE EMBBOIDERING- MACHINES.

Application filed September 22, 1921.

To all whom it may concern:

Be it known that I, MAX RICHARD BRET- SCHNEIDER, a. citizen of the State of Saxony, Germany, residing at Plauen, in Saxony, Germany, have invented certain new and useful Improvements in Fabric Frames for Several-Needle Embroidering Machines, of which the following is a specification.

This invention relates to a fabric frame for several-needle embroidering machines, and the new feature thereof consists in that the frame-parts and the suspending devices are constructed of thin pipe and furthermore that the pipe-parts are of oval section.

As is well known fabric frames exist with the upper and lower girders thereof screwed. together in the manner of a lattice-girder. for the purpose of attaining a girder with diagonal or vertical bars. However fabric frames of such construction have the great drawback that considerable wear and tear ensues on the fabric when it is placed in the frame, so that faulty embroidery is the result. In operation however, especially with frames of great length, horizontal oscillations occur, thus producing very bad work, and since the frame girders are restricted to acertain thickness it is: impossible to avoid the horizontal oscillations by reinforcing the girder-parts.

In fabric frames according to the present invention the disadvantages above referred to are completely done away with. By welding the pipe-parts together a frame construction of great strength and rigid single body is produced, and by the use of pipe, besides the advantage of light weight, a still greater stability is attained when the long axis of the oval section of the pipes is arranged transversely to the plane of the fabric frame. Thus in the latter construc tion the horizontal oscillations are avoided in a very effective manner.

Serial No.- 502,490.

The accompanying drawings shows one embodiment of my invention.

Fig. l is a front View of a fabric frame with the suspensions provided inside of the frame side-parts, and

Fig. 2 a cross'seetion on line AB of Fig. 1 illustrating the arrangement of the oval pipe-section.

The fabric frame consists of the top girder 1, the lower girder 2 and the sideparts 3, 4C. In all cases the construction of the single parts is the same. Pipe-pieces 13 of oval section are employed which are positioned with their long axes transversely to the plane of the frame. Between these the pipe-parts 5 are arranged as braces, be ing also of oval section and arranged with their axes similar to the parts 13. The

whole construct-ion is welded together so as to form a rigid body. For the purpose of journaling the fabric rollers 6, 7, 8, 9 suitable blocks 10 are arranged in the sideparts 3, 4 of the fabric frame, said blocks being of pig iron or pressed plate. In the same way the suspensions 11, 12 may be constructed, the advantages of such a mode of construction being especially advantageous with very long fabric frames.

Having now fully described my invention I declare that what I claim as new is In several-needle embroidery machines fabric frame composed of girders consisting of pipe parts of oval section, joined by means of welding, the long axis of the oval section of each of said pipe-parts being arranged transversely to the plane of said frame, substantially as described.

ln testimony whereof I afiix my signature in presence of two witnesses.
