GEORGE E. HOLLINGSWORTH, OF CHICAGO, ILLINOIS.

CHANGEABLE EXHIBITOR.

Application filed July 27,

To all whom it may concern:

Be it known that I, GEORGE It. HOLLINGS- won'rn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Changeable Exhibitors, of which the following is a specification, reference being had to the accompal'iying drawings.

This invention relates to improvementsof construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a perspective View of the box or casin of the improved changeable ex hibitor; ig. 2 is a detail plan view of certain of the sign plates and their guiding and operatin means; Fig. 3 is a detail vertical section ti-rough the mechanism for actuat-- ing the sign plates; Fig. 4 is a detail view of the slidab'le actuating member; Fig. 5 is a detail view of the lock or latch bar; and Fig. 6 is a diagrammatic view illustrating the electric circuits. 1

The invention comprises asnitable box or, caslng 1 having a sight opening 2 in whichv plates. 3 may any one of a plurality of s' be" brought lnto view. ile said sign plates may be of any suitable form and construction, they are preferably made of sheet metal and are arranged in parallel relation close to the sight opening 2 and are mounted for sliding movement in channeled guides 4 which receive their side edges. =To permiti any one of said plates to be raised to an opl erative position without interfering with to their retracted POSliZlOHS and they are the others, each one. is provided atits top with a rearwardly extending substantially U-shaped :loop or arm 5, as shown more' clearl in Fig. 2. Said loop-like arms are of di erent sizes and have their forward: ends connected to the upper corners of-- the i plates-3," while the center of their-year or;

closed portions is-fixedjto rods ,6 which are Specification of Letters I'atent.

means for operatively connecting any one of said sign plates to said actuating member. In the preferred embodiment of the invention illustrated, said member is in the form of a bar arranged at the top of a frame 9 mounted for vertical sliding movement in suitable guides 10 and shown more clearly in Fig. 4 of the drawings. Said frame is maintained in its elevated or normal position by one or more coil springs 11 and it is adapted to be depressed by the movement of the core 12 of a solenoid or magnet 13. The core 12 is freely slidable in the coil of the solenoid and is pivotally connected to the frame 9, as shown at 14.

Each of the sign plates 3 is provided with an operating lever 15 which is fulcrumed intermediate its ends at 16 and has one end connected by a link 17 to the rod 6 of one of the sign plates. To the other end of each of the levers 15 is pivoted the upper end of a controlling member or rod 18, the lower end of which latter is loosely mounted for sliding movement in a suitable guide 19 on a support 20 of fiber or other non-conducting material. Each of the rods 18 has ivoted upon it, at 21, a dog 22 ada ted to e projected beneath and in the pat of the actuating member or bar 8 so that when the latter is depressed by the solenold the rod 18 w ll be'moved downwardly and the lever 15 will be swun to elevate the sign plate 3 which it contro s. To assist the solenoid in lifting the si plate a coil s ring 23 is preferably provied for each 0 the levers 15. Said s rings have their lower ends connected to tile levers and their upper ends connected to adjusting screws 24, as clearly shown in Fig. 3. The dogs 22 which are in the form of substantially rectangular plates pivoted at one of their corners are gravity actuated able cores 27 of small solenoids or magnets 28 arranged on a bracket 29 on the support 20. A spring 30 is provided for each of the actuating arms or bell anks 25 for the purpose oi tilting them so tiat their weighted lower ends wil drop into contact with the slid a blc cores of the solenoids 28. The secondary solenoids 28 and the primary solenoid 13, as hereinafter e x'plalned, are'included in an electric circuit which, when closed, causes one of the Solenoids 28 and the solenoid 1.3 to be energized so that the arm 25; of the energized solenoid 28 will project its dog 22 into the path of the actuating member 8 so that when the core 12 of the solenoid 13 pulls the bar 8 downwardly the latter will depress the rod 18 and lift'one of the sign plates 3.

In order to break such electric circuit and at the same time maintain the actuated sign plate in an elevated and exposed position the lower end of each of the rods 18 is adapted to depress a switch lever 31 and it is pro i' l lli i piteiee i or shoul r 32 t engage lock or latch bar Said latch bar 32-} is coln non to all. of the rods 18- and is pivpte d at 3 54 in suitable brackets 35 on the pp t l Proje ted by a c l sp in do arranged between the support 20 and an arm provided upon it so that said latch bar normally projects into the path of the projections 32. Each of ttie latter is substantially y-shaped so that i s inclined or beveled lower portion will swing the latch bar and pass the same as the rod 18 moves downnardly in order that said latch bar may p ing fi er th flat p 1 e d o s ould th proj c ion 3 n h r by e ain h r d 8 in i er d si and, c n eq e y 1 0 2 th g p i s levatedina all o f'the projections 32 on the rods 18 are of th lie ize i w l be s en t efternii of the rods 18 has been g ctuated and its proje tion .3 can t by he at h .33 and; o ill be h d own y sa d at h n l the ass s ng m mber s ag in p ated to w r n her o e of th reds Tl ie lest ment n d e ii being depressed sen t p oje io 2 t e tiiz t ti hi 33 so that e? the latter releases the rod 18 already lowered at i -l s and reta n the red h h W t? la t lowe ed and whi h nmat i f r lea the first mentioned rod. Each of t e syyitph er .1 is pivot d i ter ediat ts nd at 37 on a bracket 38 on support 20 and has one o ts rm or end disp sed in the P th i one o h Hide 1 and t othe e d p n.- ie iiirqiigh a sl t in the suppo t 3 nd conne ted to t e contest member or stem 3 Qia oi Sw t h The .ette compr ses a m tal r 4 i9 arr nged HPQI it one sitt ng bracket and ennte aiiie'e l :"l stem or we .8 Fran is H t-. the err 441 aiid it e d i adapted to i nle t the b tom q the rep, wh rls are: terms tlieothei an:

tact member of the switch. The stem or member 35) contacts the cup or member 40 lfienealh the surface of the oil so as to prevent sparliing and in order to prevent the upper portion of the stem 39 from contacting the cup a sleeve 43 of non-crmducting material is arranged upon said stem, as shown.

lhe several solenoids are controlled by nienns of a key-boa rd consisting oi. a plurality of circuit closing switches or keys each of which comprises a resilient inen'iber 45 provided with a finger piece and haying one end fixed and its other end adapted to engage a contact 41.0. The electrical. connections are clearly shown in Figs. 3 and 6 and con' prise a eol'ldnctor 47 between each key 45 and one of the switch cups 40, a conductor 48'leading from each bracket 38 to one of the solenoids 28, a conductor tit) extending from the solenoid 121 and havin i a plurality of branches leading to the solenoids 28 and a conductor 50 extending from the solenoid 13 to the contact strip 46' of the several keys of the switch board. Said conductor 50 is adapted to include a suitable electric generator but in the present embodiment of the invention it contains a cut out switch 51 and is connected to the wires 52 of an ordinary direct current electric lighting circuit of from 110 to 125 volts. It Will be understood that the keybmll'fil may he located. at any point close to or distant from the casing 1 and that the (K'JllLlHCl'OLS 47 between the switch board and easing may be inclosed in a cable, as indiated at 3- Heying thus described the invention What i ann d 1.
