WEAVING FRAME Filed Aug. 9, 1934 ATTORNEYS Patented pr. 1935l Y WEAVING FRAME .Iulius Bechhofer, Teaneck, N. J., assigner `to Bernhard Ulmann Cc. Inc., New York, N. Y., a. corporation of New York v Application August 9, 1934Serial No. 739,101

`3 Claims.

The object of this invention is to provide a weaving frame provided `with adjustable features in order that the user thereof may extend or diminish the size of the frame tovarious sizes in order that fabrics of different sizes may be Woven thereon.

Weaving frames of the knock-down character have heretofore been provided having adjustable features but such frames have been found objectionable for various reasons. Some types of these frames were provided with intereengaging notches but were objectionable in that, if the frame were dropped, or pressure brought toA bear against one of the individual elements of the frame, during manipulation,` the frame would collapse. shrinkage of the material of which the frame was made, the parts would become loose and the frame members disengage and the frame lose its shape. Other types of devices with? respect to theirv adjustable features were objectionable in that the individual members were,A not locked together and,` in order to adjust the frame to new positions the spacing of the members had to be t carefully measured in orderto square the frame.

kThe present invention overcomes 'the fore` going objections and permits the frame to be adjusted to different sizes and locks the frame members in positionagainst movement, provides for compensating for shrinkage of the frame material and ensures that the frame members will be retained in their adjusted position underfall` conditions.

Fig. 1 shows a perspective `view of theframe in assembled position; Fig. 2 is a side velevation of one of the frame members; Fig. 3 is an enlargedtop view of'two of `the frame members in assembled position, and Fig. 4 is a sectional view on the line 4-4 of Fig. 3. i

The frame consists of four separable like members I. Each member, preferably constructed of wood, is provided with a series of slotsZat the top edge thereof, thereby providing a multiplicity of upstanding lugs 3 to which threads are secured for the purpose of weaving. Each frame member I is provided witha series of holes II passing entirely through the lower edge of the -frame member below the base of the slots. One end ci each frame member is provided with a wood screw 5 having al threaded post portion 6 extending beyond the end thereof a distance slightly 1in excess of the thickness of each frame` member. A wing nut 'I is adapted to screwlupon the threaded post Gof thewood screw. Z-shaped locking members 8 are each provided with a` hole 9 so that each locking member 8 may be threaded over the screw mining the desired size to which the `frame is` It was also foundfthat due to the (Cl. 28-15) t a to be formed,'positions one of the locking members 8 over` each of the screw threaded posts 6 andthen passes `the'extension 6 through the nearest hole 4 in the adjoining frame member I corresponding to the determined sizeV of` the irame. Each locking member will assume a po,

sition as shown` inFigA with itsupright portion ,8a against theend surface of one frame member,

rwith its lower leg 8b against the vunder surfaceV `of the frame member and its upper legv 8c over the top edge `of theadjoining frame memberl. The wing nut I is then screwed over the threaded .post 6, and is drawn'tightly againstV the side surface of the frame memberagainst which it bears,

thereby forcing adjoining Vframe members `together and securingv the locking memberlbetween two frame members with the legs 8b and 8c bearing against surfaces of `the frame members,V

' whereby the frame members are secured in position and locked against all possible rotation and rigidly, without the Vpossibility of the frame members becoming loose Aor moving out'of position.

I claim: A Y Y 1. In a weavingframe, in combination, a multiplicity of apertures in aY frame member, a post, carried by one of said frame members, adapted `to pass through said apertures, a `locking member, said locking member being adapted to enj gageasurfaceof each of two adjoiningframe over the top surface of one of said frame `members ,and under the underside of the adjoining" frame member, and means cooperating `with said post to draw adjoining Vframe members together and retain the locking member finl position.l

3. A weavingframe, in combination, a multi-V plicity of frame members, having a series o slots and upstanding lugs formed in one edge thereof, locking members engaging the frame on the surface opposite the surface in which said slots and. llugs, are formedMeach locking member having a portion engaging asurface of the next adjoining frame memberV and inter-engaging screwthreaded means adapted to exert tension onsaid 55` locking members tosecure adjoining frame mem` bers together. securely and in predetermined position.
