UNITED STATES GEORGE P. BUTLER, OF BOSTON, MASSACHUSETTS.
GN-f Application filed October 1, 1926. S rial No. 139,002.
This invention relates to improvements in signs. More especially it relates to improved construct-ion, particularly adapted for outof-door'signs, whereby their ability to withstand the stress of weather and other attacks is increased. The invention is applicable to signs having one or more indicating boards and provides for the selective setting of the boards as to direction, with respect to the supporting post or to one another, and for locking them securely in such position. It also includes improved means for locking the sign proper upon its supporting post to the end that the same may be securely held against inadvertent displacement.
Street signs ordinarily have to be in the form of boards, usually at the top of a post, and it is desirable that they have two visible faces and that the margins be finished. The
common practice when making signs for indicating diverse directions. i. e. double signs, is first to send someone to the location and determine the desired angular relation between the boards and then to construct the sign as a complete unit with the boards fixed in the position they are to occupy relative to each other on the post. This involves making special mountings designed to accommodate the particular angle desired, and consequently such mountings arenot interchangeable.
Stock parts cannot very well be made up and each sign must be treated as a' sort of special task. This greatly delays the installation of a sign after its needis felt, and adds materially to its cost. I
It is an object of the present invention to provide a standard construction for mass production, such that signs which differ in'dividually, as for a large number of city streets, can be made and assembled cheaply in finished self-protecting form. It is an important feature that standard parts may be quickly and easily assembled to produce signs having a single indicating board or signs having a plurality of indicating boards, and that the respective boards may be positioned,
. at the time of installation, in any of diverse angular relations with respect to one another, and may be securely locked in the particular selected position. A further feature is that the signs may be manufactured without regard toand even without knowledge of the proposed location or the angles required at the intersection of streets where they are installed. Another object is to provide means wifiiin the device and completely concealed from view and protected, for retaining and locking the sign proper upon its post. It is moreover an importantobject to employ a principle of construction such that signs which are in a very superior sense durable may be produced at moderate expense.
These ends are attained by providing two sign plates set back to back instead of the usual single board or plate, each having the characters indicating the street appearing on one of its faces, one form of constructing these plates and their lettering being disclosed in my copending application No. 625,986 filed March 19, 1923, According to the present invention these plates are mounted on opposite sides of athin central support which may be at the top of a post, or, in the case of double signs, may be mounted above the lower sign board; Marginal clampingstrips protect their top'and bottom edges and seal the space between them; and end caps,
which may be riveted in place, secure the whole. The sign plates by interengagement of the cover and clampingstrips with the thin central support and end caps are held against removal vertically or horiontally.
Thus a composite sign plate having the appearance of being a singleboard or plate can be made, with metallicv characters mounted on the face and fastened on the back of each board, with fasteningsfully concealed.
The central support of the lower sign board is made to telescope with the top of the post and has an internal self acting bolt which looks the two together and is concealed from view. Biit the bolt quicklyand easily may be actuated. by a person familiarwith thesign structure, to unlock the sign proper from its supporting post, for removal.
The central support of the upper sign board has a depending huh socket opening downward and formed internally with many pairs of parallel sides. When a sign having two indicating boards is desired it is only necessary to position. an upper sign board above a lower one, the depending hub socket from the stud. setting at the sign is thus correct and permanent; yet such signs can be made, in mass production, without knowledge of the angle at which they are to be set; and each may be set at anyanglm The invention may be applied in various ways, one of which is illustrated in the accom-i' ig. 3 is an elevation ofithe lower central supporting member, with portion in, medial section; V y

Each board embodies two sign plates 16 which maybe constructed of any desired material with characters on their exposed faces indicating the streets. These plates are mounted back to back on opposite sides of thin central supporting members 18 and 20 which are in turn secured together andlocked on the post- *Each meniberhas a rectangular frame and at top and bottom is provided with horizontal flanges 19 which overlie the top and bottom edges of the plates '16. The lat Q ter are bowedaround their central supports.
with their ends together so that wedge shaped spaces are formed between the two sign plates. The openings of these spaces are closed by four tapering strips 22. Each strip has a rib 22 centrally of its inner face which fits between thesign plates and extends slightly beyond the inner end of the strip, to engage under, or on as the case may be. the flange 19 on the central support.
formed on each side of the strips 22, near their Flanges 22? are inner ends, and engage the outer faces of the two plates 16, tohold them against the central support and against the rib 22? extending n outward between them. The end of the strip the ends of the sign plates.

means may be employed to hold the end- Bivets 26 or other secure fastenings' caps '24 permanently in position. Addition al rivets 28 may be used at the center it desired, but are not necessary, because the endmetalplug 30. A hole 30, extending horizontally through the plug, constitutes a housing and guide for spring-pressed selfacting' bolts 32, which are urged outward throu oppositely arranged holes 18 inthe thim le 7 and into oppositely arranged holes 10 in the 0st when. the two sets of holes are brought into register. As illustrated, each bolt 32 in formed with a shoulder 32' against which a spring 34 presses and by which the outward movement of the bolt is limited. 1e inner ends of the springs abut against arod36 which extends axially through the plug :30, through the central support 18, and through an up or hub 38 at t e top of the support 1 8. is rod while serving as a stop forthe bolt springs 34 primarily gives strength and rigidity to the sign as a whole being headed over at top and bottomon the hub 38 and plug 30 respectively. y
It is important that the lockin means be concealed from view and protects end there is provided a collar 40 which fits around the post 1'0 and has an inwardly extending flange 40',-which rests upon the top of the post just under the circular base plate 18" of the central support118. This collar is placed on the top of the post before the thimble 18 is inserted so that as the latter descends, the spring urged bolts 32 will. overbolts eventually enter the holes 10. in the post, the latter are covered by the collar and the locking means thus hidden from view. To remove the sign from the post the collar To this lie the flange 40" of the thimble. To. enable 40 can be turned until a hole 40" therein is opposite one of the holes 10 whereupon a pin or the like can be inserted to disengage one bolt from thepost. The thimble istipped upward a little to bring that bolt out of alignment with the hole 10 and thus hold it retracted whilethe collar 40 is then turned half way round and the opposite bolt likewise V disengaged. With both boltsthus tree from the holes 10' thesign may be removed from post.
The feature of the invention wherebysingle .manufaotured in quantity.
signs maybe readily convertedinto double signs, and whereby selective setting of an upper sign board with respect to the one beneath it is permitted is important and tends toward greatly reducing production cost of signs. The vertically rising hub 38 on the top of the lower central support 18 is formed with many pairs of parallel faces38 oppositely arranged; and has a groove 38 of substantial depth extending completely around it. The central support 20 of the upper sign board has a depending socket hub 20 formed interiorly with an equal number of oppositely parallel faces so that it can be slipped upon the non-round hub 88, with any angular setting with respect thereto that may be determined when the sign is erected on its location. The engagement of the respective fiat surfaces prevents any rotative displacement and endwise removal is prevented by a pin. 20 which passes through a boss 20" on the hub 210 and engages in the groove 38% When headed at both ends, this pin securely locks the upper sign to the lower sign.
Any strain imposed upon the top sign board is transmitted through its connection with the hub 38 to the rod 36. Likewise any strain on the lower board is transmitted direct to this rod. As a result the sign as a whole is extremely strong and durable.
It is evident that the various parts may be Only the sign plates 16 and the marginal strips 22 need be made in different sizes to accommodate signs of difierent lengths. It only one sign board is to be erected, a special cap can be at tached to the hub 38 by a rivet engaging the grove 38 to enhance the general appearance.
I claim as my invention 1. A sign comprising, in combination a hollow post; two sign boards arranged one above the other at the top of the post, the lower board having on its top a vertically rising non-round head and on its bottom a depending cylindrical sleeve adapted to telescope the top of the post, and the upper board having on its bottom 21 depending socket, internally formed with many equal sides to receive the non-round head of the lower board;
