R. REINER STRETGHING FRAME FOR EMBROIDERY MACHINES Filed July 28, 1922 MIN VENTOR A TTORNEY Fatented Dec. 30, 192%.
ROBERT RE I NER, OF VJEEHAWKEN, NEW JERSEY.
STRETGHING FRAME FOR EMBROIDERY MACHINES.
Application filed July 28, um. Serial No. 578,048.
To all whom it may concern:
Be it known that I, ROBERT REINER, a citizen of the United States of America, residing at lVeehawken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Stretching Frames for Embroidery Machines, of which the following is a specification. I i
The present invention relates to a stretching frame for embroidery machines and its object is to provide a construction in which a piece of fabric or article of any suitable character, like a stocking, handkerchief or the like, can be readily mounted and stretched in position.
In the accompanying drawing, Fig. 1 is a front elevation of a frame embodying my invention; Fig. 2 a section thereof on line 2-2 of Fig. 1; Fig. 3 a section on line 33 of Fig. 1; Fig. a a cross section on line 16t of Fig. 1 and Fig. 5 shows in elevation the separated channelled bar and clamping rodforming one of the lateral stretching members.
The stretching frame, according to my invention, comprises a substantially rectangular open frame composed of four corner pieces which in longitudinal dlrection of the frame are connected by rods 11 and in transversal direction by plates 12, 12. In order that the frame may be adjustable for various Widths of fabric the corner pieces may be each recessed as at 10 longitudinally from the inner ends thereof to engage the ends of said plates 12, 12, and the latter may be secured in position therein by screw bolts 13 or the like. These plates are extended to project outside of the frame area, i. e., the lower plate 12 downwardly and the upper plate 12 upwardly, and the extended portions are curved or grooved to form channels 14: extending transversely of the frame. The extended portion of the upper plate 12 is formed with lateral hooks 15 whereby it can be hooked to a horizontal rod 16 of the tambour frame (not shown), while the extended portion of the lower plate 12 has a central recess or opening 17 for the passage of a screw bolt 18 projecting from a transversal bar 19 of said tambour frame and to which it is attached by a thumb nut 20.
Pivoted to each corner piece at one side of the frame as at 21 is an arm 22 covered with a sheath 23 of elastic material and adapted in cooperation with the correspondof these clampingarms are extended longitudinally beyond the plates and bent upon themselves to form hooks 22 each of which is adapted to engage a finger24 pivoted at 2 1" to the corresponding corner piece, so that the' clamping arms 22 can be locked in clamping position.
For stretching the article transversely there is at each side of the frame a longitudinally extending roller or spindle 25, the ends of which are reduced in diameter and borne in cross bores 10 formed in the opposite edges of the recesses 10 of the corner pieces. The ends of the spindles on tightening the screw bolts 13 become clamped in the bores 10 so that the spindles are prevented from turning except on application of considerable force. The intermediate portion of each roller or spindle is hollow and longitudinally recessed, as at 25 being in width somewhat smaller than the diameter of the channel and at their ends somewhat widened at one side to form gross grooves 25 Adapted-to removably bear in each spindle is a flat bar 26 covered with a sheath 27 of elastic material substantially of elliptical cross section, the large axis of which is about equal to the diameter of the channel and the small axis equal to or slightly smaller than the width of the recess 25 Each bar 26 is of about the length of the recess 25 and at its ends provided with transversal projections or lugs 26 which serve as grasps and are capable of engaging the grooves 25 The sheath 27 on each bar extends only between the projections 26.
The upper end of each spindle 25 is extended and formed square in cross section, as at 25 for engagement of a suitable tool or key 03, whereby the spindles may beturned to stretch the article.
The mode of operation of my frame is as follows: V
The piece of fabric or articley is first stretched longitudinally and its cross edges clamped in the channels 14: of the plates 12 12 by the clamping arms 22. After looking these arms 22 in clamping position by the fingers'24, the bars 26 are removed from the spindles 25 and the material serted into the channels by the sheathed parts 27 of said bars which are passed into the channelled spindles 25 with their small axes lying transversely of the recess. On twisting said bars 26 around by their lugs 26 the edges of their longer axes fric tionally engage the goods in the channels as illustrated in Fig. 4'. In this position the lugs 26 of the clamping members 26 arec'aused to engage the cross grooves 25 What I claim is A stretching frame for embroidery Inachines comprising pivoted arms constituting clamping members for the ends of the fabric, means for locking said arms in clamping position and stretching members for the opposite side margins of the fabric, each stretching member comprising a hollow spindle formed with a longitudinal recess leading into the hollow of said spindle and the width of which is smaller than the diameter of said hollow, a clamping mem ber of substantially elliptical cross section, the small axis of which is about the size of the widthyof said recess and the long axis of which is substantially of the size of the diameter of said hollow, said clamping member being adapted to engage the fabric between itself and the inner wall of said hollow, when turned on its longitudinal axis away from the recess and means on said clamping member for facilitating the turning thereof within said hollow.
In testimony whereof I aflix my signatu-re in presence of two witnesses.
ROBERT REINER.
