A further object of my invention is to provide a sign holding device of inherently stable conStruction 80 designed as to prevent Warpage in the casting of the frames and to prevent the mis— alignment of the legs of the frames during the Operation of castingA further object of my invention is to provide a frame of the character described so designed as to facilitate the assembly of the sign device. A further object of my invention is to provide the frame with means to prevent the distortion of the frame during the assembly of the sign device, thereby obviating the danger. These and other advantageous objects which Will late!‘ appeal‘, are accomplished by the simple Emd practi?al Construction and arrangement of parts hereinafter described and exhibited in the accompanying drawing, forming part hereof, and in which: Fig. 1 is an elevational View of the device when I have found, in practice, that the frame parts it and ‘i may be cast with the connecting strip Hi forming an integral part of the casing; this 35 construction provides the parts 6 and ‘l with in used to indicate two intersecting streets, parts 55 being broken away for the sake of clarity, herent stability and practically eliminates any danger of the distortion of said parts during the cooling of the casting. The danger of misalign ment of the ends of the parts is also obviated. 40 The connecting strip it further prevents the free ends of the parts 6 and ‘I from being compressed inwardly with the resultant danger of breaking and chipping the plates 9 therein. The sign holding device of the character de- 45 scribed herein is used to designate street inter~ sections and the like and is subjected to inclem ent Weather and climatic conditions. The con ‘struction described herein has been found to provide an aligned, rugged frame which will not 50 become distorted in use. The construction de scribed also precludes the danger of excessive expansion and contraction of the frame due to climatic conditions. Each of the parts 6 and l is substantially U- 55 2 2,110,555 shaped and has on opposite sides semi-cylindrical bosses H and I2 so that when the frame is as sembled, the bosses ?t together to provide cylin drical bosses as shown in Figs. 1 and 3. An ex ternal rib l3 preferably triangular in cross sec— tion, as shown in Fig. 2 extends around the periphery of the frame. Passing through the bosses II and I2 is a rod H, (see Fig. 3) which is preferably provided with 10 a cap- I 5 integral therewith or threadedly secured thereto, said cap having opposing triangular grooves i6 adapted to ?t over the rib l3 of the frame, the internal diameter of the cap 15 being greater than the diameter of the cylindrical boss formed by the bosses H and I2. The cap is usually provided with an integral ornament H. When for example two sign plates are used to designate two intersecting streets the top rib is of the upper frame is engaged by the cap [5, while the bottom rib on the uppervfrarne is en gaged by opposing triangular grooves IS in av collar I9 which surrounds the bosses on'the lower side of the upper frame and on the upper side of the lower frame, (see Fig. l), the collar 19 having grooves Hi to also engage vthe ‘upper rib of the lower frame. The lower rib 13 on ‘the lower frame ?ts in groovesiZl ina collar 22 inte gral with a two-part cap ‘23 which ?tsvover the top of and is clamped. :by suitable means'to a cylindrical supporting ‘post v24. The ‘lower end of the rod H5 is preferably threaded and passes through an aperture in cap "23. In assembling the device, cap 15 is ?ttedover the bosses ‘II of the upper frame, ‘the rod M passing through the bosses H and between the sign plates 9 which are bowed or spaced at ‘the center by thestrips H] ‘to receive the rod 14, and the collar 13 is then slippedvover the rod 14 and into position over the bosses on ‘the underside 40 of the upper frame; the lower frame ‘members are then placed in position with the upper bosses il thereon surrounded ‘by ‘collar 19. The cap 23 is then positioned over the lower bosses 12 of the lower .frame after which a 'nut 45 25 is threaded on the end “of the rod 1'4 and rotated to draw the parts ?rmly together. vUp- V ward movement of the nut 25 is prevented by cap 23 so that rotation of the nut 25 draws the rod l4 downward to clamp the parts together. The cap 23 is then clamped on to the support ing post 24. Obviously when the device is used for a sign frame it is not necessary to use the collar l9. - The collar 19 is provided with a plurality of grooves 20 to enable the sign frames to be ar ranged at various angles'to each other. 10 From the above description it will be seen that 'I have provided a sign holding device of simple structure requiring no nuts or bolts, and which can be readily assembled by a single unskilled workman. The parts are ?tted together so that 15 allowance can be made for limited expansion and contraction due to changing weather. The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as re strictive or limitative of the invention, of which 20 obviously embodiments ‘may be constructed, in cluding many modi?cations, without departing vfromithe general scope herein indicatedand de Inoted in the appended claims. ' Having thus described my invention, what I 25 claim as new'and desire to secure by Letters ‘Patent, is‘: 1. In a sign holding device, a frame member comprising a pair of substantially U-shaped in ternally channelled sections, each section hav 30 ing ‘bosses at the free ends of the legs thereof, '- means surrounding said bosses to hold the sec tions together, and members connecting the legs of each section adjacent the bosses, said mem bers being positioned on the longitudinal center lines of said sections. '2. In a sign holding device, a frame member comprising a pair of substantially U-shabed internally channelled sections, ‘each section having bosses at the free ends of the legs thereof, 510 cylindrical collars surrounding said ‘bosses to ‘hold sections together,’ and members connecting the legs of each section'adjacent the free ends ‘thereof, said members being positioned on the’ longitudinal center'lines of said sections.
