STREET SIGN Application filed June 8, 1932. 'Serial No. 615,966.

This invention relates to sign display devices for out-door use, and particularly, to

the means for holding and supporting the sign plates in such devices.

Out-door signs, particularly, those used tov designate streets or roads, and customarily used at street and highway intersections,

for quick and easy assembly, replacement and repair with a minimum of labor;

Difliculties have heretofore been encountcred with such devices which clamp or fasten the sign plates in place by reason of the damaging stresses on the sign plates occasioned by expansion and contraction and changing weather conditions. Since the individual sign plates are usually finished in either baked or porcelain enamel, stresses thereon caused by changes in temperature and weather frequently cause the enamel to chip and peel, particularly around the edges.

My invention therefore contemplates the provision of a holder for rigidly supporting sign plates in such a manner that the plates are permitted to expand and contract without restraint, whereby all possible stresses or strains thereon under the conditions of nornial use are eliminated.

My invention further contemplates the provision of a simple, efficient and durable sign holder so constructed that it may be ranidlv and economically assembled by un- 5 skilled labor. and without the necessity for 7 using more than a single fastening element, and thereby eliminating the necessit for using a multiplicity of bolts. nuts, rivets, screws or other similar fastening means requiring skilled and expensive assembling.

My invention further contemplates the provision ofinterchangeable parts for the holder which can only be assembled in the proper relation, and when so assembled, are

is-rigidly locked in place, while at the same should time assuming the stresses on the holder,and relieving the plates held thereby from all normal stresses and strains.

The various objects of my invention will be clear from the description which follows, and from the drawings, in which,

Fig. 1 is a top plan view of my invention as it appears assembled but with one of the plate-holding frames partly broken away.

Fig. 2 is a front elevation of the same.

Fig. 3 is a side'elevation thereof;

, Fig. 4 is a perspective view of the post on which the frames are assembled.

Fig. 5 is a perspective view on an enlarged scale of a pair of identical and interchangeo able frame members adapted when assembled to form the finished frame, and showing the members vertically separated from each other. I

6 is a vertical central section of my 5 invention showing the various parts assembled and in their operative posit-ions.

'Fig. 7 is a front elevation of a, modified form of the means for clamping the holder to a supporting post therefor.

Fig. 8 is a vertical section of an end portion of one of the sign-holding frames, illustrating the use of a vertical spacer inserted between the frame members to increase the effective height of the frame, and thereby to 75 ,permit the use of larger sign plates.

It will be understood in what follows that my invention may be advantageously employed at street intersections, and at any points on roads and highways where it is de-, sired to post information such as distances, names, directions, or warnings, and particularly, where a supporting post or bracket can be advantageously used. 4 i

In the practical embodiment'of my inventi on which I have illustrated by way of example, the supporting post or bracket may take the form of atubular member 41, which may be firmly set into theground, or which may constitute the end of a pipe or other bracket supported in any convenient manner, and

which is preferably arranged with its axis vertical. Secured to the upper end of the support 41 is a suitable cap 42, provided with a perforation or openings in its upper surface for the passage of the lower end of the post 24, and provided with. suitable internally threaded openings 34 for the reception of set screws for clamping the cap to the post 41. The frame-supporting post 24 and the parts carried thereby are preferably first securedto the cap 42 whereafter said cap is arranged on the end of the supporting post 41 and secured in place'together with the sign holder and sign plates carried thereby.

Suitable means are provided on the upper surface of the cap to permit the arrangement of the sign holding frames for proper visibility and to lie in the required plane. As illustrated, said means includes a pair of spaced lugs 30, designed to enter a pair of selected cooperating recesses in the serrated. locking element 21 on the under side of the lower" frame member 11', as will be more fully explained hereinafter.

As shown in Fig. .7, the set screws passing through the cap to clamp 'itto the post 41 may be dispensed with. In this case, the cap 33 is split part-way along a circumferential line parallel to its top and is also partly vertically split to provide a yieldable portion thereon. The body portion of the cap, as well as the split portion, are eachprovided with.

a perforated outstanding lug, as 31 and 32 respectively, through the perforations ofwhich is passed the bolt 44. It will be understood that on tightening the bolt, the cap is firmly clamped to the end of the post 41 whereby the parts carried by the cap are rigidly secured in place. Said cap 33 also carries a pair of spaced lugs 30 for the purpose hereinbefore mentioned in connection with the cap 42.

It willbe understood that the caps 33 and 42 are perforated at their upper ends to permit the passage therethrough of the post 24. Said post (Fig. 4) terminates at its lower end in a constricted threaded portion 26 providing the shoulder 25 thereabove. The various frame parts and sign plates are assembled on the post in the manner soon to be described, and preferably, while the post is upside down, or

in other words, with the threaded end 26 upand tightened whereupon all the parts are in one operation rigidly assembled in the required positions thereof with the frames under compression, and the sign plates substantially unstressed, as. will be pointed out in more detail hereinafter.

The various parts assembled on the post 24, and forming the holding frames for the sign plates 36 and 36, will now be described. Each of said frames consists of two members preferably identical in construction and therefore, a description of one of the members will suflice for both. Each of the frame members 11, 11 is preferably made of suitable inexpensive material such as malleable iron for purposes of economy, strength, durability and rigidity. The frame member may be of substantially U-shaped form, being provided with the cross bar 10 and the dependin g legs 16 and 14, said legs being preferably shorter than the arm and of substantially halfthe desired height of the finished frame for the purpose of receiving rectangular sign plates. It will be understood, however, that one of the legs may be made longer than the other, if desired, as will be obvious, and that one leg may even be made long enough to form a substantially complete end on the finished frame. The legs and the arm are each provided with a preferably central groove 17. On the leg 10, said groove 17 communicates with the openings 13 which 7 openings are separated, however, by the enlarged reinforcing or cross member 18. An opening or perforation 19 is made in the member 18 for the passage of the post 24. Surrounding the opening and outstanding from the member is a serrated locking element preferably in the form of a series of similar spaced outstanding lugs 21 separated by the radial recess 20.

It will be noted that the leg 14' is provided with a recess for the reception of the terminal portion of the cooperating leg portion 16' of the other frame member 11. portion may be enlarged if desired, but in any case, is of suitable shape and size to prevent longitudinal and lateral displacement 1 of the frame members relatively to each other after the leg 16 has been inserted into the re cess 15 of the member 14. A suitable shoulder 12 forms one end of the recess 15 and is adapted to abut against the corresponding end of the leg '16 to limit the telescoping movement of the frame members toward each other.

Before said membersare assembled, however, the sign plates 36 and 36 are arranged in their proper positions in one of the members. Since both of said members preferably ta'per from the central part 18 thereof towards their ends, the sign plates are consequently slightly bowed conveXly outwardly. Each of the plates is merely arranged in the groove, 17 with its long edges resting on one of the members 18, and its ends resting against the upright sides of the grooves 17,

Said recessed 1'7; The bowed position of the plate mainare assembled. It will further be seen that tains it against rattling in theframe. Since the post 24 is inserted through the openings 19, 19' and between the plates, it will be seen that said plates are maintained in spaced re-. lation at least at their middle parts but. are nevertheless free to expand and contract, the grooves 17 17'- being made large enough for thatpurpose; It will also be seen that the sign plates can in no manner be stressed longitudinally or transversely, regardless of how tightly the frame members 11 and 11 no fastening means of any kind are necessary to maintain the sign plates in their proper positions within'the frame after they have been assembled therein and therewith.

The post 24 may be recessed at various portions of its length, as by means of the triangular recesses 23 inorder to economize on material and to minimize the weight of said post. At its upper end, the post may terminate. in a. suitable ornamental head 22 under which is provided theintegral plate or shoulder 28. Depending from the under surface of said plate are the radially arranged lugs '27, of such size and shape as to enter a selected, diametrically opposed pair of the recesses 20 in the locking element of the frame member 11. 'By means of this con-- struction, the post 24 may be cast or other? wise formed ofa single piece of material and quick and easy assembly of the parts attained. It will be understood that the frame member 11 may similarly-be cast of a single piece of material, and that all of the frame members, as has been heretofore explained, are preferably identical in structure, size, andshape.

To assemble the frames and plates upon the post 24, said post is arranged substantially vertically, but with the end 22 thereof lowermost and the end 26 thereof uppermost. The frame member 11 is'then carried downon the post, which is passed through the opening 19, the frame being turned about the post, if desired, until the lugs "27 enter the selected pair of recesses 20 to dispose the frame member at the desired: angle to the post, though turning of the post is usually unnecessary. The plates 36 and 36 are now bowed and inserted into the groove 17 and on opposite sides'of the post (Fig; 6). The frame memberg11 .is now similarly passed about the post which passes through the open? ing 19 of the member, and the legs 16, 16'

inserted into the recesses 15 of the respective-legs 14 and 14, the edges and ends of the plates entering the groove 17 of saidmember.

Where a second sign frame is used, the

upper member 11 thereof is now passed about the post and turned inahorizontal plane into the proper position, whereby the lugs 21 of the locking element thereof enter the select ed recesses 20' of the'locking element of the frame member 11' to hold the upper lower frames in their required angular relation whether at right angles or not; The

plates of the second frame are now insertedinto position, and the frame member 11' also a easily secured and compressed together'by I means of the nut 35, the plates 36 and 36' remaining free of compressive stress.

It will be understood that on tightening said nut, the frame members 11 and 11' are drawn toward each other until the ends of the legs 16, 16abut against the walls ,12 of the recesses 15. v,The entire holder'thus as sembled with its cap may now be reversed into its proper uprightposition, and arranged on the post 41, as has been herein: before described. m

It will be seen that it becomes impossible by reason of my invention to assemble the parts improperly since said parts can .fit together in only one way./ It will further be It will further be foreign matter to drop out of the holder without adversely affectin the si plates held thereby. Should it be desired to adjust the frame for the purpose of taking signs ofgreater height than those normally intended therefor, a suitable spacer ofthe desired height may be interposed between the legs 14 and 16. As shown in Fig. 8 said' spacer ta'kes the form of a leg portion of the desired length andidentical in size and cross-sectional shape to that of the leg 16, and a terminal recessed portion 14 identical in shape and size to that of the corresponding leg 14 of the frame member. It will 'be' understood that when the frame members and spacer are assembled, the leg portion of the spacer enters the: recess of the leg,14 of one franie member, and the end thereof abuts against the wall 12 of the. recess The other end of'the spacer receives the leg16 of the other-frame member since'it is provided with a recess 15 identical with the rea cess in the leg 14 of the frame member. I

It will be seen-that I have provided a, simple'and-in'expensive sign holder, capable of being rapidly. and- "correctly assembled by unskilled labor, that only a single fastening operation and fastening member is required to rigidly secure the parts together ready for the attachment thereof to its supporting post, that the sign plates are held thereby loosely and without danger of stress or strain thereon such as would cause chipping of the enamel, that the parts: need not be assembled in any particular manner or order since they are interchangeable and therefore readily capable of ready and quick replacement and assemblyvand disassembly ,for

use or for repair, that there can be no ac- 1.
