Figure 1 1s a side viewof 'the"c0ntrol Figure 2 is a rear view of the same. Flgure 3 is anenlarged"verticalsectional viewof a portlon of the bank ofcontactors illustrating operation ofth'e 'sameby pas- ,contactors, the latter showing a special contac'tor type with insulating material for operation by metallic patterns.

Figure 1-2 is a fragmentary viewillustrating a portion ofthe sign-board as controlled by this apparatus.

In Figures 1 and 2 .the general. relation and arrangement of: parts is possibly best illustrated. These views show. a bank of control contacts 1 positioned to correspond -Wltl1"tl16 lamps 2 of the sign-board 3, Figure 12, Which they governa This bank of contacts is arranged ertically, sup ported thus in asmtable frame a-ivhich carries guides 5 forthepatterncarrying panels 6. These panels are-shown linked'together in the form-of: a-nendless'chain by-means of split spring rings 7 on the-ordetbf key rings which'can= be' quickly-opened up to separateany'of the links in'the-chain for "the'purpose of adding, subtract1ngorChanging characters. :The characters are=in the form of raised patterns =8 having-the shape of theletters numbers or otherfigures whioh are to be='reproducedon thesigneboard and these patterns; as best shown l11"Flgl11G 3,

' project-inwardly frointhe faces oftheir supports sufiicie'ntly toengagethie'spring contacts and to'bend the same overintoengagement with the inner ends of corresponding- 1y positioned terminal posts 9. These posts are shown set in a -suitableinsulating support 10 mountedon'the frame'a-nd as provided' 'at' theirouter ends With-"binding screws or'terminals 11 fronrwhichconductors are extended to the correspondingly po sitioned lamps on the sign. In one preferred form, these posts are made of square or rectangular stock, rounded at the outer or terminal end as at 12 and are held within the insulating support by simply driving them into round holes provided there for and until the shoulders 13 at the ends of the square portions out or seat into the insulating material far enough to lock the posts and hold them against turning.

To enable ready renewal or adjustment of the contact portions, the tips of these posts are shown as formed by round head screws 14, providing rounded contact and bearing surfaces for the contact fingers to bend over. These rounded bearing surfaces increase the current carrying surfaces and by easing the bends of the contact fingers, prevent said fingers from being injured by continued fiesing. These contact screws are exposed and readily accessible at the back of the insulating support and so can be quickly adjusted, removed or replaced as occasion requires. To uncover these contacts the chain may be uncoupled and drawn out of the guides or if desired, the chain may be left intact and shifted back out of the way after releasing the chain from the guides, one or both of the guides being for this purpose shown as a strap or bar removably secured on the back of the frame by screws 15.

In the present disclosure, the spring fingers are the leaf contacts, thus operating each time they are bent into engagementwith a terminal post to complete a circuit through the particular lamp or lamps with which such post is connected. For this reason all the spring fingers are mounted in a current conducting frame 16 suitably insulated from other parts of the machine and to which current is supplied from a suitable generator such as by the connection indicated at 17 in Figure 3. The other side of this circuit is diagrammatically shown at 18 extending from one of the terminal posts to the lamp controlled thereby.

The contact fingers are shown arranged in rows extending crosswise of the bank and each row, Figure 5, as consisting of the teeth of an integrally formed comb 19. These combs may be out from strips of phosphor bronze or other good conducting spring metal of a length to properly fit between the side bars 20 of the conducting frame 16. For mounting the comb strips and electrically connecting them with the side bars, they are shown having angularly bent ends 21 fitting flat against the inside faces of the frame bars and overturned at the upper or outer ends at 22 to overlie the edges of the bars, screws 23 being passed through these overturned lugs to detachably hold the combs in place and form current conducting engagement between the frame and strips.

The back portions of the combs are shown as reinforced by strips of insulation 2-1, at opposite sides of the same and secured thereto by screws or rivets 2-6. These insulating strips brace the bodies of the combs, holding them solid against any twisting tendency from flexure of the individual teeth and this bracing elfcct is increased by making the combined width of each comb with its insulating strips equal to the span:- ing between adjoining rows of the terminal posts. The inserted combs thus lit snugly in the slots formed between the :uljoining rows of posts and so are braced by these posts and kept electrically separate tlu-rcfrom by the insulating separators.

The insulating strip 21 at the front or upper side of each comb is shown as narrower than the back strip so as to permit the fingers to freely flex forwardly or upwardly toward and into engagement with their cooperating posts. the added width of the back strips preventing the lingers when released from snapping back into engagement with the wrong posts, at the back oi" the same. If desired, however. this back strip may be low enough or the parts so related that when released, the spring con tacts will snap back into engagement with the preceding posts and so produce a momentary flashing etl'ect following the travel of each character. i

As the pattern chain carries no current. both the supporting panels and the figures or patterns may be made of insulating material and are so indicated in Figures f), l, (3 and 7. In Figures 8 and f) a metallic panel 6 is shown carrying a pattern made o'l nonconducting material. In both forms the character is shown mounted on a sub-panel or base 27 engaged at one end beneath a loop or strap 28 and held at the opposite end by a cotter or pin passed through a post or loop 30 extending through an opening provided in the sub base. This construction, it will be seen, n'lalies it pc .ble to readily interchange the letters or cluiracters on the chain without disconnecting or changing the chain.

For supporting and driving thev chain a square pulley 31 is shown provided at the upper end of the trackway, the sides of said pulley being substantially equal to the lengths of the chain links so that said pulley will both carry and propel the chain smoothly and uniformly. This rectangular pulley is shown operated from a suitable 32 through a worm and motor 34.

A special feature enabling the condensing of a considerable length of the pattern chain within a comparatively small space. is the supporting of the chain in a series of intermediate continuously traveling loops. Two of such intermediate loops are illustrated gear drive ltlfi ll l in Figure 1 at 35, 36, the first hanging between theback of the drivepulley and. an intermediate idler squarepulley 37 and the second hanging betweenthis intermediate or running oversprocket wheels 40 on the pul ley shafts. 'Thesupporting pulleys may be removable andinterchangeable so that one,

two, or in fact any number of them, may be used, depending on'the' length of chain in the machine andthe number of loopsin which it is draped.

7 From the last supporting pulley, the chain.

is directed'back to the contact bank by suitabl means such as the guide channel 41. This channel is shown as having its side flanges 42 secured at the top of the frame bar 43 in whichthe rolls or pulleys are ournaled and as having its side flanges at the bottomspread apart and resting on the floor or supporting structure so as to brace and V steady the rear of the machine; The back or web of the panel is cut away from between the side flanges at the bottom approximately at the point'44 to allow the chain to swing between the supporting side flanges forwardly in agradual curve where it is shown guided by an idler 45 betweenside gages 46 which positionthe links to pass freely beneath the inclined lower ends 47 of the guide rods 5.

As a further possibility, metallic characters on metallic supportsmay be used 1n the machine as "indicated in Figure 11,.but 111 I such a case it is desirable to insulate the tips of the contact fingers where they engage with such letters as indicated at 48 to prevent electrification ofthe chain.

By-placing the characters eitherhorizontally or vertically on the chain, the apparatus may be used to operate either a horizontal or a vertical sign, without changing the apparatus in any way, By feeding the patterns upwardly, a smooth continuous 'and uniform action is obtained and a machine capable of handling a sign of very large dimensions may be built into a comparatively small space. The looping of the intermediate portions of the chain enables the handling of agreat length of chain within a relatively small space, permits the chain to runv freely.without'friction or cramping of any kind and enables inspection and changing of the chainreadily to meet various requirements The various parts of the machine can be simply and durablyconstructed and the current carrying parts are inexpensive and can be readily. adjusted or renewed.
