To all whomy it may concern.:

Be it known that we, ALFRED ll). AN Toune, of Chicago, Mrnoiv H. RICHARDSON, ot' Cl'iicago, .and Aline-urli). Gunnar, of'ViL mette, all inthe countyl of Cook .and State ot llinois, and citizens of the United States, have `invented certain .new and useful lInipi'oveineiits in Picture-Exhibiting Ajpparatus, ot' which the following is a specifica# tion. y A N This invention -relates to improvements iii ,picture exhibiting apparatus of .the type in which a kplurality of ,pictures or views, pre't'erablyo `the stereoscopic type,are arranged within a casingfand` adapted to Vbe successively brought into position to be viewed through Windows or glasses7 the shitting and changing 'of ythe Vviews Vbeing controlled by mechanism adapted to loe set into operation by the insertion of a proper check or token.v 4 i ifi Ylurther Objectis to provide an iniproved apparatusV of thisr character including means whereby a predetermined .number ot views or ,pictures may I' be displayed during each period of Aoperation of Athe apparatus. I.

A Yfurther object is to provide an .imv.iroved apparatus of this character in .which there is provided a rotatable .View supporting member to which the views are pivotallyv connected, the views being successively brought into position Vto be viewed lfrom a predetermined point-,and improved means .tor imparting a quick OrO-snapping movement to the views abouttheii' pointfofpivfotal connection with the said support, as the views approach Ila predeterminedpoint in the cycle of operation ofthe apparatus.

A fuither object is to provide animprovedfdevice of this character iii vwhich the vier.' support may be readily# disconnected from the actuating means thereforA and removed with the views a -unit 'from the casing,without Vnecessitating dismanf tliiig ol the actuating imechanism or other ,parts ot the .apparatusv thereby rendering it possible to intercliangethe viewsandsupportstheiefor as a unit. I

To the attainn'ient 1 of. .these ends and 'the accoiiiplislinient ot other `new and useful objects as will appear, the invention consists in the r4jeatui'es of .novelty -in substantially the censtruction, combination .and arrangement of the .several .,parts, "hereinafter more fully .described and claimed and lshown in the laceompanying idrawings `illustrating this invention, andinwhich--- `Figure l is a vertical sectional `View of an apparatus of this character, and .as taken on l,iiie=1-..1,Figuie3.

The other end the mem-ber 17 is'fbent vback upon itself as at 2l ('see'.Figures Sand (i) and theextremity thereof is preferably shaped to forma reduced finger 22, which co-operates with the 1 portion 18 to hold the card-20.- therebetween.v AA pivot pin 23 is clamped between themembersrl'? andthe turned back portion V21 and is secured to the member 1n ,s any suitable manner, so as to prevent the pivot pin from rotating withv respect to the member. Any suitable means may be provided for thus vholding the pin and member against relative. movement.

The ends of the pivot pinV project beyond the ends `of the turned back portion and'one extremity of the pivot pin is deflected as at 24 tov form an arm. A 4shoulder 25 is formed` on the member 17, adjacent the pivot pin, for a purpose VVto be set forth. f

The members 17, any number of which maybe provided, are pivotally connected betweenthe members 10 and 11 ofthe drinn by passing lthe pivot pin k23throu'gh regis' tering apertures inl the elements 10 and v11 and iii-Such a manner vthatfthe arms or deflected extremities24 of the pivot pins will stand adjacent'the outer face of the element y11. lVhen the lmembers. 717 arerthusQconnected With the drum it fyvill be manifest that the members together with the cards will be mounted for movement with -the drum vand Wit-lr respectthereto. The shoul- Vders 25`on themembers 17 serveas a means .for limiting the extent of movement of.` the `members '17 about their pivots.y Arranged adjacent. thevouter face ofthe elementv` 1l is a support 26, which is preferably pivotally mounted upon the axle or shaft 13 and and adjacent the face of ,the element 11 is a member 28, preferably provided with an arm 29V having a portion 30, which is [disposedadjacent the path of movement of the deflected portions 24 ofthe pivot pins' 23v Aso that asthe drum like structure or vieW d carrying support Iis rot-ated, the portions 24 of the pivot pinsA 23 will successively' en'- f gage thep'ortion or surface 30 to rock the card carrying members 17 about their pivots vwith respect to the drum like structure.

Connected with the member 28andfal'sov with the' support 26, is a spring 31,v which tends normally to'move themember 28 in one di;

rection aboutitspivot- 32and the member 28 'is also provided With an arm 33, the extremityV 34 of which is disposed in close i lproxiinity to the projecting portions of the pivot 'pins 23 VandV co-operated therewith to form afratchet like.construction,v for the purpose of holdingthe arm 29 and the sur# face 30Goft1he Ymember 28 againsty movementV under thenormal tendency of theV spring 31. `This extremity 34 of the arm 33 will, however, ratchet with Vrespectjto thc yprojecting portions ofthe pins 23,vv as 'the view carrying support is rotated in the Vdi` rection ofthe arrow in Figure 2, which will,

during'the advancingY movement of the View carrying support, cause the member 28, when ment with one of the pivot pins, to move 'the extremity 34 of the arm 33 is in engage- 5 about its pivot 32and`against the stress of the spring 31. That is to say ythe member 28. W1ll have ai Y slight rocking Y'movement' about its pivot'32 as the view carrying sup# 34 of the arm 33p`asses out of engagement;

This Willmove the surface ofthe arm l29 in theV opposite direction about the pivot 32 with a sudden or 'quick movement.. vDuring this movementthe surface V30 willrengage vthe deflected'portion 24 `Vof the next advancing pivotpin23 and will imparta quick or Vsudden movement to the respective card carrler 17,V thereby causing the view'or picture lto be 4thrown about its pivot quickly lwhen itI reaches va` predeter`` mined point inthe operation of the appara tus, ythereby 'insuring-'fa proper changing ofv the view and lalso Without obstructing for any unnecessary period of "time the next ad vancingview or picture.

' The" extremity 3.1 Aof thearm v3?, lengaging the` pivot pins also serves as a means` for'holding the surface 7 30`in yak proper position. 1

".The parts thus'c'onstructed arearrangefl Within a housing or casing'vdesignate'd..gen-

erally by the reference numeral 35 provided j j j With Windows for adn'iittinglight in- Y. f to the casing and glasses'38, through which 1 the pictures may be yviewed. j Y

The front of rthe casing is `open andV isV rovided WithA al removable closure 39. ounted upon one of the side walls of the casinges` an open bearing 40 '('see particularly Figures3 Aand 4)V and supported by theV opposite Wall of the casingisa rotatable bearing or socket 41 arranged in `alinement` with the-bearing, 4o. The bearing 4o is preferably spaced a slight distance from its j supporting Wall Vso that when thel view carrying supportand theshaft` 13 are inserted into the casing throu'gli'the open end there of, oneextremityof the shaft -13maybe inserted in the rotatable bearing or socket 41', after which the other'extremity` of the shaft is placedY Within the bearing 40. As

CII

a means for causing the shaft 13 to rotate with the bearing 41, the latter may be provided with openings 42, in which a lug or pin 13 carried by the shaft 13 is adapted to be seated.

As a means for holding the shaft i3 against displacement `with respectv to the bearing L10, there maybe provided a suitable locking device such as a bar Vor rod ed (see also Figure 3) adapted to `slide in a suitable bearing 45y carried by the casing wall. The forward end `et this bar or rod lf-t terminates adjacent the open wall ot the casing` and the extremity is shaped to 'l'or'm a handle d6, by means et which the har or rod may be moved in its bearing The rear extremity di' of the bar or rod eid is deliected latere and the deflected portion is adapted to i .ove over the open hearing 4l() to lock the shaftin ,position in the bearing. VJhen, however, it desired to remove -die view carrying support, the har or rod del is moved inwardly or l'o the lett in Figure il, until the deflected ex tremity 47 moves away 'from' the hearing ell), thereby permitting the shaft to'be raised out ot the bearing and when thus raised nary be shi'lted longitudinally so as to disconnect the other extremity of theI shaft 'from the rotatable bearing or socket el.

Any suitable means may 'be provided 'tor rotating the bearing or socket tiel, such as a spring motor device embodying a train ot gears d8 49-5U5l5253 (see particularly VFigures l and 3) arranged within and mounted upon the side. wall ot the casing preferably upon a plate or support 541e, (see Figure'l) secured in position by fastening devices so as to permit the device to he readil \1 removed as a unit when desired. Conner-ted with the gear 53 is a toothed escapement element 5G, with which an esca-pement lever 5.7 co-operates. The latter is provided with trunnions 58 mounted in suitable bearings and escap'ement teeth 59, which cooperate with the escapement element 56. Adjustably mounted on the element 5T are weights (3() tor controlling `the speed ot oscillation ol' the element 57.

Rotatably mounted upon the bearing or socket el is a gear 6l and connected with the gear Gl for movement therewith is an arm (l2. Carried by the arm 62 is a dog G3, which is movable therewith and with respect thereto. This dog G3 is adapted to co-op crate with a series of lugs or projections Gd extending laterallyftrom the tace' ofthe gear d8. These lugs' are arranged at predetermined distances from each other, according to the exten-t of movement or rotation which it is desired to impart to the bearing or socket el-l upon each step ot `operation ot the apparatus. In the present term ot the invention tour or" these lugs or projections are shown, thereby insuring a one-quarter revoyimparting"such rotationv to the geartl.

ber or'l views or cards 2O upon each operation.

Obviously the number of pins or projections Gel may be increased or decreased according to the number ot' views desired to display upon each operation.`

Connected with the arm 62 and with the dog 63 is a spring 65, which latter tends normally to move the dog 63 in aposition'vto pass behind one of the pins or lugs 64,- when the arm 62 is moved to the lett in Figure l.v is this arm is moved in that direction `the end or' extremity 66 of the dog 63 will Vpass behind the adjacent pin or lug 6d, so that' when the arm 62 is released and is moved in the opposite direction or toward the right in Figure l, and the gear 6l rotated Vin a manner to'be now described, the gear 48 and bearing il will ybe correspondingly rotated to rotate the View carrying support.

Any suitable means may be employed tor A suitable and etticient'ineans embodies a rack GT which meshes with the gear Gl. This rack is connected with an arm or lever G8, pivotally supported intermediate its ends as (5S) vdupon the plate 54. The rack may be secured to the arm 68 in any suitable manner such as by nleans ot a fastening device T() 'nrssing'through a llanged portion 7l ot the rack. A spring T2 is anchoredfhy one extremity as at 73'to the arm 68 and by its other extremity as at 74- to a fixed support 7 5. The spring 'T2 vis `so arranged that yits normal `tendency is to `move the rack V(5T toward the lett in Figure l so that the parts will assume the position shown in full lines in AFigure l. To' start the apparatus extremity' T6 of the arm orlevert38 is moved in a direction toward the lett in' Figure l. its the rack 6T vis connected with the yarm 68, it will be manifest that such movement of the arm willadvance the rack 6T byv drawing the. same forwardly Vor toward thev rright in Figure l. This will rotate the gear 6l and as the arm or support (32 is connected with the gear (3l the arm will be swung toward the lett in Figure l, carrying-with it the dog 63. When the arm (32 has been moved a sutlicient distance to permit the end 66 ot the dog 633 to drop behind one of the lugs or projections G45 on the pin d8 through the medium ofthe spring' 65, the lever 68 may be released. During this movement of the lever 68 vand before being released tension is being created upon the spring T2 to store energy therein so that when the lever 68-is released theenergy in the spring 72 will operate upon the lever 68 to move the latter in the opposite directionV about rits pivotand with it the "rackr67. yAs the dog 63'is locked behindone vof the pins or projections 64, itvvill be manifest that as the rack 67 is Vmoved under` the tension of the spring 72 to swing the arm 62 forwardly, the advancing movement of the arm 62Vwill rotate the gear 48. The arm 62 will continue to move underthe iniiuente of the rack 67 vand-gear 61 until thearm 62 engages a stop,

which latter may,if desired, be the pivot 69' of the lever 68. WV hen the parts assume the positionshown in full lines in Figure 1, the

YAll of the propelling and the setting mechanism just describedniay be mounted upon the plate 54, so that the same may be removed as a unit or may be installed as a unit in the apparatus.

. Any' suitable means may be provided for swinging the lever 76 about its pivot against the stress of the spring7 2. lAV suitable and' elicient means embodies a crank arm 78,

Vhaving a roller79 connected therewith and which crank arm is connected with a shaft 80 for rotation therewith.Y A spring 81 is anchored to the shaft 8O by one end and by its other end as at 82 to a iiXed support. The crank 78 may be rotate-d by means of a suitable handle V83 arranged on the outside of the casing, while the crank 78 and spring 81 are arranged on the inside of the casing. When the crank 78 is rotated in an anticlockwise direction the anti-frictionroller 79 will engage the end,7 6 of the lever 68 and rock the .same against thek stress of the spring 72. This rotation of the crank 78 will Acreate a tension upon the spring 81`so that when the handle 83 is released the spring 81 will return the crank 7 8 to the position shown in Figure y1 and the lever 72 will be returned bythe spring 72 and will be retarded in its movement through the medium of the gear 61 and rack 67.

y The operation of the crank 78 may be con-` trolled in any suitable manner but preferor tokenis inserted in the check controlled mechanism, the handle 83 and crank arm 78 `will be released to permit operation thereof.

- It is thought that the operation of-,this apparatus will beclearly understoodA from Vthe foregoing, but briefly stated it is as follows: The normal position of the' parts are as shown in full'lines in Figures liarnd 2. lVhen a check isinserted in the check Vcontrolled mechanism the handle 83 and crank arm 78 are rotated to swingthe lever 68 to the left injFigurel and also move the arm 62 with the dog 68 thereon to the left and intoythe position shownin dotted lines in Figure`1u ntil the endV 68 of the dog 63 passes behindrone of the lugs 64. The handle 83is thenreleased and the stress of the spring 72 will be exerted'upony the lever 68 to return the latter. This return movement, however, is retarded by means of the escapement devices 57-56 and the train of gears 48%53. The gear-48funder the stress of the spring 72`vvill` rotate in a clockwise direction and will continue to so rotate until the arm 62 engages'theJ stop 69,- at which time the motion of the parts will be arrested.

Then the check is dischargedfrom the check controlled mechanismit will pass throughf'a suitableopening 85 into vthe enclosing housing or casing.y i v When it is desired, the front 39 of the casing is removed and the locking bar or rod 44 is moved inwardly so as Vto uncover Athe open bearing 40. The view carrying support may then be removed bodily as a unit by raising the end of the shaft 13, which me Y rests, in the bearing 40, a sufficient distance to permit the shaft 13 to be moved longitudinally so .as to disengage the extremity thereof from the rotatable bearing 41, after cessively display theviews as the support` yis rotated, so that they can be .viewed through the'glasses 38, by means of the arm 27, which is loosely mounted upon thel shaft 13. This arm 27 is of' a sufficient. length to extendA downwardly and terminateadjacent the bottom of the enclosing housing or casing and ifV desired an vele1`nent786, preferably in the form of a screw or bolt is threaded through a .lateral projection'87 on the armV 27, so as to engage the bottom of the housing or casing.

mounted upon the shaft 13 and inasmuch as it carries the element 28, any degree of movement ofthe ar1nv27 about its pivotalsupport It will be mani-` Afest that inasmuch as the arm 27 is pivotally will shift .the member 28 and consequently the surface SO. Therefore, by adjusting the screw or element 86 so as to vary the distance of the extremity of thev arm 27 from the bottom of the casing, the position of the surface 30 may be varied 'to vary the time at which the deflected portions 24 of the pivots 23 will engage such surface.

It may happen'vwhen the reel or view carrying support ris removed from the casing and re-inscrted or a new one inserted therein, that .the view support willv not be in a proper positionmso that the opera-tor will be able to see the proper'views at the commencement of anyone section of the views carried byv the view. support, and therefore the openationtof the device under vthose conditions would result in the operator viewing a portion of the views in the two sections rather than all of the views in one section. i

It vis the purpose of this arm 27 and the adjustable element 86 to obviate this dificulty and that is accomplished in the followingy manner. The member 28 is soconnected with the arm 27 that the vsurface 30 will always be maintained in the proper' position with respect to the glasses 38, but in taking the reel and the arm 27 carried lthereby out of the casing or inserting` a new one therein, the reel may have been rotated with respect to the surface 30. Therefore, when the reel is placed back into ,the casing the arm 2T may be raised with respect to the reel or view carrying support, with the result that the free extremity thereof will projett through the open face of and beyond the using. It is immaterial what position this arm 27 assumes when the reel is being placed `back into the cas-infr. After the reel -has been properly positioned and in order to adjust the reel with respect to the surface 30, all that is necessary is to insert Va proper check into the mechanism and start the apparatus into operation. Under these conditions the Yarm 2 7vwill travel with the reel or view carrying support until the eX- tremity of the element SGeng'ages the Abottom of the housing or casing, at which time the movement of the arm will be arrested, as will also the movement ofthe element -28 and surface 30. The reel or view carrying support will, however, conti-nue to rotate until the arm 62 engages the stop G9, and this will happen just at the time that the end of any one particular section ,of views has been reached'7 therebyplacing the vfirst view or the descriptive card of the neXt section of lviews in a position to be viewed through the glasses lt will be manifest that'with this im-` proved apparatus energy for each step of the operation thereof is created by the insertion of a check 'or token, or the setting of the apparatus for each particular operation thereof. That is to say, when ,each checl is inserted the setting ,of the appartus as a result thereof, for operation, will store energy `enough inthe spring 72' so that in one particular operation thisenergy will .be about expended, thereby rendering it unnecessary to maintain thespring' 2'con- `stantly under a considerable tension.
