I 16 claims. (cmo- 125) This invention relates to display signs and has particular reference to lmockdown signs.

One object of the invention is to provide a sign having improved means including block-like members whereby any desired indicia can be ob- ,v tained.

The invention aims particularly to provide a sign whichcan be shipped in parts and which can be rapidly assembled by any one with ordinary mechanical skill, and which shall replace the paper signs frequently used to announce a change in price of a commodity or other infomation. It is well known that such paper signs have to be printed, and in the case of large establishments,

to be disp layed,and. that they are rapidly destryed and become unsightly due to wind and weather. By this invention, if the sign be used to designate the price of' gasoline, the company supplying. this product need merely telephone or otherwise inform its stations of a change in price, and the signs can be reset to immediately announce such change.y

Another object of the invention is. therefore, to obviate the defects and to obtain the advantages above mentioned, and further to provide a particularly simple and inexpensive sign structure, and one which is especially clean, neat and attractive in appearance, and which is durable, reliable and emcient in use and convenient to manipulate.

Other objects and advantages of the invention will become apparent` as the specification proceeds.

With the aforesaid objects in view, the invention consists in the novel combinations and arrangements of parts hereinafter described inv ktheir preferred embodiments, pointed out in the subjoined claimsand illustrated in the annexed drawings, wherein like parts are designated by the same reference characters throughout the several views.

The advantages of the invention as here outlined are best realized when all of its features and instrumentalities are combined in one and the same structure, but, useful devices may be produced embodying less than the whole.

It will be obvious to those skilled in the' art to which the invention appertains, that the same may be incorporated in several different con-- structions. The accompanying drawings, therefore, are submitted merely as showing the pre- 20 ferred exemplication of the invention.

Referring in detail to the drawings, 10 denotes a display or knockdown sign embodying the invention. 'Ihe same may include an inverted U- shaped frame of one piece angle iron, having 25 upright members 11 interconnected at the top by a cross member 12. These members thus have anges such as v13 and 13a respectively, lying in a common plane, and anges such as 14, 14a at right angles thereto.l Also intercon- 30 necting the upright members 11 in spaced relation to the lower ends thereof is an angle member 15 having a flange 16 connected to the flangeslS as by bolts 17 and having a bottom flange 16a at right angles thereto. Additionally intercon- 35 necting the upright members 11 are vertically spaced cross bars 18 jand 19 which are located between the cross members 12 and l15 in spaced relation but in relative proximity thereto. Each of the members 18, 19 is a duplicate of the other, 40 and one of them is inverted relatively to the other. 'I'hus each of the members 18 and 19 may be of somewhat deformed H-shape in cross section, having along one side a relatively wide chanl nel 20 and at its opposite side a relatively narrow 45 channel 21, the respective channels 20 and 21 of the members lying in common planes, and the channels 20 facing each other, while the channels 21 face their adjacent angle members 12 and 15. These cross bars 18 and 19 liebe- 50 tween the flanges 14 of the upright members 11 and are connected as by screws22 to the flanges 13 of the upright members.y v

Fitted in the grooves 21 `and extending back of and along the flanges 13, 13a and 16 of the 55 adjacent frame parts are rectangular plates such as 23, 24, which may be spaced therefrom as by washers 25 and connected to the flanges 13a and 16 as by bolts 26. The plates 23, 24 thus reenferce the frame and are particularly intended to carry permanent indicia painted, impressed, imprinted or otherwise disposed thereon, as indicated at 27.

Fitted in the channels 20 are a plurality of upright separate elements such as 28 adapted to engage therebetween block-like indicia forming members 29, which are detachably connected to horizontal cross rods 30, that are individually releasably attached to the different elements. 'I'he arrangement may be best understood by ilrst describing the members 29.

Each of the members 29 consists of a piece of sheet metal pressed into channel form, so as to have a front or display faee portion 30 and side anges 31 at right angles thereto. 'I'he portionv 30 may be of square or other suitable shape and the flanges 3l may be of substantial depth and may each be provided with securing means such as recesses 32 formed by tongues 33 at the cut away lower corner` portions 34 of the flanges, whereby entrances are afforded to the slots and the latter are located substantially centrally between the upper and lower edges of the members.

The members 29 may be variously interchangeably arranged in diierent positions and relationships to afford any desired numeral, letter, indicia or legend, as shown for example, at 35, 36 in Fig. 1. Preferably the members 29 are arranged with their channels vertically dispose-:l and with their upper and lower edges 37, 38 respectively abutting each other in their planes. The front faces 30 of the members may have any suitable color, such as red, and in order to better illustrate a desired character, certain of the niembers may have cut away portions as shown at 39, 40 in Fig. 1, but preferably as illustrated by members 4i, 42. Thus the member 41 may have a lateral central v-shaped cut out 43 in the face portion thereof, up to the adjacent side flange 31 thereof an-:i leaving the lat-ter entirely intact up 'to the plane of the face portion, as indicated by the edge 44 of said flange. Likewise the member 42 may have a corner 45 eut away in the face portion, this cut away extending along the plane of the face portion past the adjacent flange 31, forming the edge 46 in the latter. The nature of the construction, generally similar for both 41 and 42, is well shown in Fig. 4, the flanges 31 being otherwise exactly the same as in the member 29.

Each of the elements 28 is of vertically elongated channel form and includes a back 47 and side flanges 48, 49, the latter flange having in turn a laterally extending longitudinal lip or ange 50 which may be parallel to the back 47. 'I 'he anges 48, 49 may have a series of oppositely disposed aiined holes 51, for a purpose hereinafter described. It will be noted that the outside width of a'n element 28 is such that the member 29 may closely embrace the same, so that the flanges 31 slidingly engage along the outside of the anges 48, 49. 'I'he vertical spacing cthe holes 51 may be equal tov the height or distance between the upper and lower edges 37, 38 of the member 29.

The elements 28 are adapted to lie with their backs 47 in a common plane, side by side, and with a flange 50 of one member overlapping an adjacent flange 48 of an adjoining element 28 as clearly shown in Fig. 5. t is thus noted that thereby lare formed vertical vnarrow channel spaces S, which may receive the flanges 31 therein, and which are further adjustable to snugly engage or frictionally grip `said flanges, as hereinafter described.

Extending through all alined holes 51 of theelements 28 is a guide or rod 30, and a series of such rods are provided to pass through all the vertically spaced holes, whereby the rods are equally vertically spaced, and reenforce the elements 28 and support the same. Ilhese rods necessarily span the channel spaces S, and the flanges 31 are arranged so that the tongues 33 hook over the rods, the latter being received in the slots 32.

One end 52 of the rods 30 may abut one of the anges 14, and the other end 53 of said rods may lie in spaced relationl to the opposite flange 14. Preferably the elements 28 are disposed so that a flange 48 lies in proximity to the last mentioned flange, and such element 28a may differ from that at 28 solely in having horizontally elongated slots 54 whereby the element 28a may be adjust-ably secured to the adjacent flange 13 by bolts 55. It willnow be seen that the elements 28 and 23a may be moved transversely along the rods 30 to leave sufdcient space at S for the mounting of the members '29, after which said elements may be moved closely toward each other, toward the right in Fig. A5, and the bolts 55 tightened.

Obviously any number of elements 28 and rods 30 may be used, and desirably the uppermost and lowermost rods are spaced further from their adjacent cross bars 18, 19 than from each other. 'I'he cross bars 18, 19 may be omitted if desired, as shown by the modication 10a of Fig. 10, and the guide rods 30a may be passed through alined holes in the upright members 11a of the fame, and secured. at their ends outside oi' the frame as by nuts 5e. In this arrangement the elements 28, 28a may thus be carried wholly by said rods, and the construction may other,- wise be the same as in the device 10, as Ithe elements 28, 28a may merely abut the adjacent edges of the plates- 23, 24.

'Ihe manner ofassembling the device will now be described. The framev having the cross members 15 and 19 secured thereto as shown, the elements 28, 28a are assembled as on a table and the rods 30 passed therethrough. 'I'hen this assembly is bodily inserted into the channel 20 of the member'19, and swung into the frame, after which the bar 18 is connected in place. Finally, the plates 23, 24 are attached.

In use, the members 29 are individually connected, their anges 31 being inserted between the loose elements 28, and hooked to the rods 3i), in which position the anges 3l may abut the flanges 50 for steadying the members, and the front portions 30 being spaced in front of the backs 47 of the channel elements 28. in this way, any desired indicia -can be rapidly built up or changed as may be necessary. When this operation is completed, the elements 28, 28a are all moved laterally, and the bolts 55 tightened, whereby the sign is completely set up. The sign can be readily knocked down in the reverse manner.

The appearance of thel sign is an extremely' important factor of the invention. The front oi the sign is marked by uniformly spaced vertical lines S' that are relatively inconspicuous since the spaces S are very narrow. The indicia forming members neatly conform to each other and are symmetrical with the lines S', and stand out from the background of the back portions 47 of the elements. There are no daylight spaces through the signs. in view of the rear flanges 50 at the spaces S. The rods 30 are wholly at the back of the sign, and provide a neat appearing regular formation with the flanges 50. 'I'he sign can be readily cleaned or washed, and since the members 29 are vertical and provide vertical unobstructed channels with thin edges, dust and other foreign matter substantially will not readily settle or accumulate on the indicia. Each member 29 may of course carry a complete letter or numeral so that a series of members can be used to form a word or other indicia.

In Figs. l1 to 13 is shown a modification of the invention including a sign 60 which is precisely similar to the device 10, except that the indicia forming members may be releasably locked against unauthorized removal, and that the channel members 18, 19 are removed, as explained for the device a. Also. as shown in the device 10a, the rods are extended through the frame.

More specifically, the indicia forming members 61 have their side flanges 62 provided with open ended upright slots 63, the closed ends whereof are enlarged as at 64, so that the rods 65, which are oblong in cross section, may be readily receivedin the slots through the open ends thereof, and then rotated through an angle of 90 degrees in the enlargement 64 to afford an interlock. Each of the rods 65 passes through holes in the parallel iianges of the upright frame member 66 and through the parallel flanges 67, 68 of the channel elements 69, these holes being, for instance, round to permit turning of the rods as above set forth. Each of the rods has a head or handle l0 at one end, and at its other end a hole whereby a pin 'I1 may be passed through all the rods to prevent reverse turning and'unlocking of the rods. In operation, after members 61 are assembled and elements 69 locked as at 54, 55, the rods 65 are turned and the pin 71 inserted to lock the same.

It will be appreciated that various changes and modifications may be made in the device as shown in the drawings, and that the same is submitted in an illustrative and not in a limiting sense, the scope of the invention being dened in the following claims.
