i To all whom it may concern-b Be it known that 'l, Ronnie's Emivtn'r'r HINOHEY, a citizen of the United States, residing at i-rurora, in the county of Lawrence .e of Missouri, have invented new and useful Improvements in a (hie-Story Moving Display Advertising Machine, of which the followingis a specification and is illus rated in the accompanying drawings.
Myinyention relates-to a onestory, twosection moving-display advertising machine, with means to successively display cards bearing advertisements, photographs, illus trations, designs, etc. 'ihe operative mechanism comprises, a. Combination of one set of machinery secured to the bottom of a horizontal rectangularrshapedx supporting-frame,
a series of vertical card-display carrying frames arranged in sets, one set to each section. Said sets or frames rest upon two like transverse slides or run-wajvs and are bodlly' movable transversely, in oppositedirections, the diagonally opposing. endmost-frames be ing delivered into the horizontal portions of an endless-track, .where they are individual-, lyand consecutively transferred from one set to another and vice versa. ltis notable that many featu-resvof my machine are similar totlie advertising devlce disclosed .111 my 'copending application S. N. 413,504,'filed Sept. '29. 1920, which is a two-story device,
having-"both horizontal and vertical movements. The machine is for bother-either interior orexterior displays of any size from'2 213 inches to 20 X SO-feet or larger, according to requirements, and may have anynuniber 'ofdisplay-carrying frames from three up.
1 is a flatview of the lower part of the machine as'seen' by looking down upon it;
1g. 2, a perspective of the front elevation of the ZLPPfl-liltuSSllOWIl in Fig. 1. w
I attain the foregoing features by" the,
series of like frames supported by the second section D. These frames maybe of the same material as the supporting-frame F, each made with a groove in the innerpart and] I preferably openat the top toreceive card's bearing advertisements that, maybe slipped in back-to back, in order that the displays 41 maybe presented to viewf on both 'sidesj o porting-frame ll is such that the sectionsG the machine; The construction"ofthe, supopening, making in all four openings, op-
posite" which] four; different advertisements. mav be viewed at all times, each display'be ing exposed to view twice on its side of'the machine. f
Thecard-jsupporting of the'setsierh f and B areqmovable. in what we may-,term'an" indle'ss-pathway, the first section 4C andthe second section D constitutes 1 the two transverse SQCtlOIlS'OI"pOTt10I1S iOf sa d endlesspathway, and will, therefore, be ClGSlgIlfltGdf hereinafter"interchangeably with Saidsectionsas C and D,jin-which one set of frames' A. are Tmovab1e,,forwardly and bodily, in the first transversesection,or portion G, and the other setof frames 13 are movable inani'opposite direction, rearwardly andbodily, in j the second transverse section, or'j'portion. D; lneach instance after the above'm'e'ntioned 1 bodily movements, the dlagonally opposing endmost' frames 5 are adapted to be trans ferred. singly and consecutively. from, one
set. as A through the front 'horiz'ontal .por-,
tion E, to the other-as B, and vice' fversa, through the rear 1 horizontal card-displaying portion E, bymeans of notches 4 cut in the center ofthe under edge of the frames 5, co-operating directly with a stiff-pin 3 that is mounted on. an. endless-chain carrying-de-. vice 1, locatod in the bottom'of the appa ratus, under said sets of frames A and'LB. Said endless ehainisbperated by al'arge sprocket-wheel 2, fastened to a gear-shaft O that is continuously rotated by the driving gear N, (any suitable gear may be 'used,) which, in turn, is'engaged by the operative power, preferably an electric-motor M, (see Figll shows the. endless-chain 1 passed about the aforementioned sprocketwheel 2, and one small sprocket-wheel 22,
ported under "section fiC. Said sprockets 1. 10
- supportingframe F.
wheels, so positioned, are adapted to balance and ginde said endless-chain 1 in a horizon ,tal rectangular position, in order that a single stiff-pin 3 mounted thereon, may have co-operatron with the several parts of the tent movement, bodily and singly, of all the frames 5 tnrough said endless-pathway, composed of the transverse portions C and D, and the horizontal card-displaying portions E and its maybe seen by Fig. 1, said endless-chain 1 is supposed to be continuously in motion, so the above mentioned intermittent movements are governed by the time it takes pin 3 to travel from one cooperative part to the next, engaging and releasing them in turn, as will hereinafter be more fully described.
By reference to Fig. l, the dotted lines I represent the positions of the card-receiving frames 5, arranged 111 sets A. and B, showing the evenline up of the notches el, that are cut in the center of the under edge of each frame, serving in the transverse sections C and D, as a passage forthe actuating pin 3. lVhen in the horizontal card-displaying portions E and E, said notches l become oooperative with said pin 3, to effect individual movements 'ofthe-frames 5 from one set,
A, to the other, B,"and*vice-versa. Pin 3 having arrived at the points where it turns about sprocket- ewheels 2 and 25, respectively, it leaves notches l in frames 5. To obviate the possibility of the movements not being suflicient to place the frames exactly in their proper positions relative to the other-frames 5 in the sets A and B, oscillatory hookedbars 18 and 21, are provided to catch in said notches & of the endmost frames 5, operating to pull them in: into line, ready to be delivered into the transverse portions D and C. Said deliveriesbeing made by the pressure of succeeding frames 5, .in the. passing, against spring-lugs H-H' on front elbow-' levers 1010, and spring-lugs I-lon rear elbow-levers 88, (the upper levers 8 with springing I" not shown in drawing, but supposed.) f t J lVhef in the transverse sections or pertions C and D of the endless-pathway, the cardsupportingframes 5 are bodily movable, by means of said spring-lugs functioning simultaneously with opposing stiff-lugs, all of which are provided .on the outmost arms of two like sets of similar opposing, oaeratively connected, pairs of corresponding upper and lower elbow-levers,.that are pivoted inside of the top. and bottom of the ,Of these pairs of elbow-levers with their operative lugs, tne 'two lower ones consti-;
tut-ing'two half setsareshown in Fig. 1. In
- the front part of the-machine, lever 10 bean a sprlng lug H, represents acentral le-v ver, which is linked by a horizontal rod 16, to an opposite outmost elbow-lever 10 having a. stiff-lug K. Said rod 16 also has op erative connection with an elbow-lever 9, located in section 0, that is actuated by pin 3 on the endless-carrier 1. In the rear of machine, Fig. l, lever 8 bearing a springlug 1 represents an opposite central. elbov'- lever, which linked by a horizontal rod 15 to similar outmost elbow-lever 8 having a stiff-lug J. Said rod 15 functions the same as rod l6, except that it operates in an opposite Clil ..tion, connecting with an elbowlever 7 in section C, that is actuated by said pin @f the upper corresponding pairs of elbow-levers, only the outmost arms of the front said levers are shown, (see Fig. 2,) 10 hearing spring-lug H represents the cent upper elbow-lever linked by a horizon tal rod 16 (not shown in drawing,) to an outmost elbow-lever 10 with its stiff-lug K.
in the rear of the apparatus, Fig. 2, the upper corresponding elbow-levers, not shown in the drawing, but maybe designated herein, by corresponding numerals and characters as 8 bearing spring-lug I, linked by a corresponding horizontal rod 15 to an outmost elbow-lever 8 with its stiff-lug J.
' site positions, and are adapted by means of said lu gs lllt;, operate on all four corners of each co-operative endmost frame 5, thereby moving all of the frames 5, one against the other, t'ansversely in opposite directions, the distance of the thickness of one frame. 5.
The bodily movement of said frames 5, rearwardly, in the second section D, may be effected by said spring-lugs HH, that are pivoted on the outmost armsof elbow-levers 1010, to engage the projections G, on the upper and lower inmost corners'of the front endmost frame 5, assisted by stiff-lugs KK that are integral with the outmost arms of elbow-levers 10-10, adapted to hook over the top and under the bottom, near the outmost corners of said endmost frame 5.
The bodily movement of said card-receiv ing frames 5, forwardly, in the first section C, maybe accomplished by similar springl s ll that engage similar projections (a, upper and lower, on the inmost corners of the diagonally rear endmost, frame 5,
sisted'by similar st-iti lugs J--J that hook over the top and under the bottom, near the outmost corners of said frame 5.
The central levers have the spring-lugs HH II pivoted to their outmost arms to permit them to spring back behind the projections G on the opposing endmost frames 5, while the opposite arms have loops or slots P, to allow-them to slip back on rods 15 and 16, without moving said rods and other parts of the mechanism when said levers -1.0', 8S by the pressure of the passing frames 5, are being pushed in,
Said rods and 16 have nuts on them that catch and pull said levers 10-10,
8-8" when the frames 5 are to be moved bodily in the sections C and D, turn-buckles R to regulate their length and restrainingsprings Q, on their ends where they join their respective actuating levers 7 and 9, to obviate the possibility of breakage or stopping of the machine. The rods and levers are returned to their normal positions by small springs S.
A link-chain 1 moved by a sprocketwheel 2 has in it a stiff-pin 3 that extends up far enough to catch in notches 4 in frames 5, also to engage the ends of certain levers hereinafter described as it comes to them. Pin 3 catches in notch 4 of the endmost frame 5 of the first section C, transfers it to the vacant space in the second section D, leaving a space in first section C. By curving around sprocket-wheel 2, pin 3 leaves notch 4 releasing frame 5, passes on through notches 4 in several other frames 5 to engage elbow-lever 6 that, moves straight-lever 17 which in turn oscillates hooked-bar 18, operating to, catch in notch 4 of said released frame 5, thereby complet-i ing the horizontal movement in placing said frame 5 in the proper line to be delivered into the transverse section or portion D. Said delivery being made by a succeeding frame 5, in the passing,pressing spring-lugs H- H against the projections G of said preceding frames 5, lever 7 that pulls rod 15 rocking elbow-levers 8 8 thereby turning shaft 11 that runs up in the space L between the two sections 0 and D, operating simultaneously two corresponding elbow-levers 8 8 that are above the movablein the first section C.- All four I J, I J operate to move all frames 5 in first section C, forwardly, to fill up the space in the front part of said section C, and to leave a space in the rear of said first section C. Pin 3 passes around small sprocket-wheel 22, preparatory to catching in notch 4 in the endmost frame 5 in the rear of the second section D, operating to transfer said frame 5 to the space in the rear of first section C, leaving another display in view in the rear of second section D.
Pin 3 curves around sprocket-wheel 23, releasing said frame 5, moving on to engage elbow-lever 19 that operates lever '20 which in turn oscillates hooked-bar 21, operating to catch in notch 4 of said released frame 5, therebyv finishing the horizontal movement that might not have been quite completed by pin 3, in placing said frame 5 in line to be delivered i'ntothe transverse section Or portion C, in the rear of section C. The delivery of said frame 5 from the rear, horizontal portion E into the transverse portion G, is accomplished by a succeeding frame. 5, in the passing, pressing spring-lugs II' against, the projections G of said preceding frame 5. Pin 3 passes on through several notches 4 in frames'5, to engage elbow-lever 9 that pulls rod 16, rocking upper and lower elbow-levers 10' 10', 10 1O simultaneously by means of connecting shaft 12, operating to move all frames 5 in the secondsection D, rearwardly, filling up the space in the rear and leaving a space 25 in the front of said second section D. Pin 3 moves" on to engage notch 4"in the front endmost frame 5 of the first section G, transferring said frame 5' to the space 25 in the front of second section D. These movements are repeated as longas the machine'is kept running.
