This invention relates to signboards of the allmetal frame type, and particularly to the marginal molding construction and mounting therefor.
Signboards of this type comprise a skeleton framework, a panel structure for receiving the matter to be displayed and an edge mold constituting the framing element for the panel structure. Heretofore, so far as I am aware, it has been the practice to provide the edge mold frame with separate corner sections of angie form set into the frame.,
The primary object of the present invention is to interengage the molding sections at the corners by means of a novel slip joint connection to prevent the use of separate corner sections in the mold frame and to so join the other sections at the corner as to not only provide a miter joint of pleasing appearance but to simplify the construction, cheapen the cost of manufacture and greatly expedite the erection of molding on signboards of this type.
Other objects and advantages of the invention will be apparent from the following detailed description of the invention, and from the accompanying drawings illustrating the same, in Which- Figure l is a front elevation of a signboard ernbodying the invention, with the paneling removed and with parts broken away; Figs. 2, 3 and 4 are enlarged sections on the lines 2-2, 3 3 and 4 4, respectively, in Fig. l; Fig. 5 is an enlarged section on the line 5-5 in Fig. 1 shown in perspective; Fig. 6 is a fragmentary section on the line B-S in Fig. 5; Fig. '7 is a face view of the two corner parts shown in Fig. 5 with the parts sep-- arated, and Fig. 8 is a section on the line 8--8 in Fig. 5.
Referring to the drawings, designates the uprights, which are spaced horizontally and of suitable number to suit the length of the signboard, and 2 the horizontal stringersJ which are mounted on the front sides of the uprights in vertically spaced relation and in number suitable to the height of the signboard. These uprights and stringers are preferably, but not necessarily, of angle iron.
The edge mold structure is designated 3 and is supported by suitable brackets attached to the frame members l and 2. The mold frame 3 is of rectangular form with right angled corners and comprises top, bottom and side sections.
Each mold section includes a face portion 4 having, in the present instance at its outer edge, a part 5 which is angled in cross-section to form an edge bead, the face portion 4 extending from such bead toward the center of the signboard and in a slight rearward direction, in the present instance in a somewhat ogee curve form to give a pleasing mold face appearance. The inner edge of the face portion 4 is turned outward relative to the center of the signboard to form an edge hook part 6.
The bead 5 at its outer edge preferably continues rearwardly and attaches to suitable supporting brackets. This outer edge portion of the molding may constitute an integral part of the material forming the parts 4 and 5 or it may comprise a separate metal piece welded, or otherwise suitably attached to the edge bead 5, so as to give the outer side edge portions of the mold sections a iinished appearance, as .is customary in mold frames of this type. In the present instance, the top mold section is capped by a channel member 'I' (Fig. 2), which has its channel facing downwardly with its outer side web lapping the outer side of the bead part 5 and welded, or otherwise suitably fixed thereto. The channel l is supported by brackets projecting upward from the upper ends of the uprights I and secured within the channels by bolts 9.
The bottom section of the mold frame is attached at its outer side to the uprights` I by bracket arms Ill, being in the present instance bolted to the uprights and to the inner side of the inturned side edge portion II of such section, as shown in Fig. 4. The inner edges of both the top and bottom frame sections are engaged and firmly held in properly spaced relation to the frame members I and 2 by hooked brackets I2 bolted to the respective top and bottom stringere 2 and having their outer or forward ends angled and extended into hooked engagement with the inturned edge portion t of the molding.
Each side mold frame section is supported by double arm brackets t3 bolted to the ends of the stringers 2 and having an outer arm extending forwardly within and bolted or otherwise suitably secured to the rearwardly extending outer side portion I4 of the mold section and having an inner arm extending forward and in hooked engagement with the inturned inner edge portion 6 of the mold face.
The miter joints at the corners of the frame, and in which the primary feature of the invention resides, are made by cutting the ends of the face portions 4 of the mold sections at a 45 bevel, so that the beveled ends of these portions will lap each other a short distance preferably not to exceed an inch, and with the beveled edge of the outer lapping section disposed to register accurately at its inner end with the inner corner angle of the mold frame. These lapping beveled ends of the mold sections are held in closely engaged relation by one or more metal clips l ixed, as by welding, to the inner side of the outer engaging member and having the free ends thereof extending lengthwise of the mold section in free engaging slip joint relation to the rear side of the adjacent beveled end section of the frame. It is apparent that clips l5 cooperate with the end of the mold section to which Xed to provide such section with an end socket for receiving the mating end of the adjoining section in slip joint manner. This is of primary importance in assembling, as it maintains a close corner joint and allows for a certain endwise adjustment of the interengaging members which may be necessary in setting up the mold frame due to some inaccuracies in cutting of the lengths of the sections. While the corner end of the inner engaging portion 4 of the mold sections has been described and is shown as being cut on a bevel, it will be understood that this is not necessary, inasmuch as the form of such edge is disposed at the rear side of the other lapping section and therefore cannot be seen from the front of the frame. The inturned lipor liange 6 at the beveled edge i8 of the outer engaging mold section is notched or out at an angle, so as to form a tongue I9 to have hooked engagement with the inner edge of the engaged section, as shown, thus cooperating with the clips I5 to retain the engaged edges in close slip joint relation.
The corner end of the bead part 5 of one section is notched to permit the interengagement of the adjacent end of the other corner section therewith. In the present instance, the bead of the horizontal section is notched to permit the extended end Iia of the adjoining vertical section to iit therein, the notch being such that the outer side of the bead of the horizontal section is left int'act to lap the outer face of the vertical bead. The respective outer side edge portions of the mold sections, which at the bottom corners are il and I4, are joined in a rearwardly extending straight line along their adjacent end edges.
It is apparent that the present corner construction enables the mold frame sections to be easily and quickly joined at their corners, with the joint between the ends of the face portions Il of the mold having the appearance of a miter` joint and with said portions at such ends closely held together in interengaging slip joint relation and in a manner to permit of slight relative adjustment of the sections without affecting the appearance of the joint, as may be iound necessary in assembling the mold frame sections.
I wish it understood that my invention is not limited to any specific construction, arrangement or form of the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claims.
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent, is:
