The section of `the recordbetvveen-iolls y1.6 i

yBSP@rudi-11g i111 diameter to .the'rolls 1.6 :and

, advanced across the opening 5 in the direction of the short dimensions of the pictures and opening 5V will be arranged to correspond with the disposition of the pictures. In view of the foregoing dimensions of the pictures, thev diameters of the feed rolls 16 and 17 are suchthat in one revolution of either roll, the record is advanced for a` distance corresponding to the short dimensions of two pictures or, in-the present instance,

approximately six inches. lThe pictures are,

' however, regardless of the distance through which the sheet moves in the rotation of either of the rolls 16 and 17 successively and periodically displayed through the y opening 5. In order to accomplish this result, one section of the sheet is held against movement While the opposite section is advanced in the present instance for six inches. This'movement on that section of the sheet between rolls v8 and 9 is intermittent and in adirection toward the right, as indicated by the arrows in Figure 7. The slack which results in the moving section of the record sheet is taken up by an apparatus operating with a see-saw motion and which is adapted to effect displacement and substitution in the opening 5 of pictures to besuccessively displayed. Referring now to Figures 6 and 7, an upper pair of correspondingly sized and axially parallel rolls 21 and 22 of a carriage provide a support for the section of record sheet 7 between the rolls 8 and 9. The rolls 21 and 22 are spaced apart, and the lrecord sheet is directed downwardly between the-said rolls so asV to form a loop, as indicated by b in Figure 7.V VRolls 21- and 22 are parallel with rolls 8 and 9, and are journaled in the opposite side members 23Y and'24 of the carriage frame. The lower side members 25 and 26 of the carriage frameare connected to the upper members as by uprights 27 so that the carriage will move as a unit. The ends of the upper side members 23 and 24 are fixedly connected to one end of a plurality of flexible elements 28 'which are supported by fixed pulleys 29-29 arranged in the corner portions of casing a and mounted on transversely disposed spindles 30-30. From pulleys 29 the flexible elements 28 extend vertically downward and are connected to cross-bars 31--31 at the opposite ends of `25 and 26 and are supported by pulleysV 35 disposed midway between the pulleys 29 and the axial plane of the rocking frame. From Y the pulleys 35 thev flexible elements 34 extend vertically downward and are connected to the cross-bars 31 adjacent to the'flexible elements28. V IVith this construction, the rocking frame operates to reciprocate the carriage across opening 5, the construction of the parts being such that the vertical central line of the fra-me located at a point between the rolls 21 and 22 moves beyondop- V'posite sides of opening 5 Vin eachrre'ciprocation of the carriage. Thekportions ofl the record sheet between thev rolls 17 and 19and 16 and 1 9 are looped, as indicated by c and al and directed obliquely upwardly and outwardly, the adjacent sides of the loops being supported by oppositely ,disposed rolls 36'arranged parallel with and slightly below the axial planes of rolls 11 and 12, the said rolls 36 having theirends journaled in the side wall 13 and partition 14. V'Ihe looped portions b, c, and d are connected tofloatingly mounted supports by being extended around rolls 37, 38 and 39 which, as shown in Figure 5, are rotatably'supported between outwardly extending arms 40 of brackets 41.v

Pulley sheaves 42 are mounted between cen` trally disposed spaced'arms 43 extending outwardly from the base portions of bracket 41 and an endless flexible element 44 is trained around the sheaves 42 and directed upwardly between sheaves 45V centrally located on spindles 46 arranged in spaced relation and carried by the lower side bars 25 and 26 of the carriage. yA pair of oppositely disposed fixed pulley sheaves 46 and 47 are supported by spindles 48 at points be` low the vsheaves 45 of the carriage land thev outer run of the endless flexible element 44 is directed laterally and in opposite directions from the sheaves 45 and trained around .remote sides ofV the sheaves 46 and 47. The inner run of endless ilexiblepelement 44 is supported by fixed pulley sheaves 49 and 50 arranged downwardly and in# wardly from the pulley sheaves 46 and 47 and carried by spindles 51 which are supported by the side pla-te 13 and partitionV wall 14.

With this construction it is obvious that when one of the feed rolls, for instance, the roll 16 is held stationary and the'other feed roll 17 is rotated for one revolution, loop cl will be shortened and loop Zi lengthened by reason of the movement of roll 38 toward roll 17 and the movement of roll 39 away from the upper rolls 21 of the carriage. It

will be noted, however, that by virtue of the movability of roll 39, the length of the descending movement of that roll will be equal to one-half the distance which the record moved under the action of feed roll 17, it bepulley sheave42 is such as will afford this degree of movement, and a1 like amount of movement will-be had on the part of the roll 38 which supports loop cl. In this way the amount of record displaced will be taken away f rom loop d and will be taken into loop Z). lVhen loop b is so lengthened and loop cl shortened and the carriage moved from the position shown in Figure 7 to the opposite side of opening' 5, then the area shown as being-exposed in Figure 7 and indicated by c will be displaced and moved into the upper portion of the adjacentside of loop b while the. area uppermost on the opposite side of loop t will be substituted lfor e in the opening 5. During this action on the part of the carriage, itis assumed that the section of record between the rolls 8 and -9 is stationary. `When the carriage is on the remote side of the openingfin Figure 7 as just stated and loop b extended, ymovement kon the part of feed roll 16 in the direction of the arrows in Figure'7, will operate when roll 17 is held stationary to short-en the loop to the extent shown in Figure 7 and thereby withdraw an amount of record equal to that previously taken into the loop. When this has been done and the carriage moved to its original position, the second picture will be displaced from opening 5 and substituted by a third picture. I

Lln Figure 1 a drive shaft 52 is journaled in side wall 15 andpartition 14 with one end extended beyond side wall 15 and adapted for connection to a suitable source of power which, in thepresent instance, is shown, as a manually operable crank handle- 53. Drive shaft 52 in the embodiment shown, is rotatable clockwise and operates a spur gear wheel 54 keyed thereto to operate' a pinion 55v with whichit meshes and whichis keyed to a shaft 56 uponl which is disposed an idler gear wheel 57 which meshes with a correspondingly sized idler 58 fixedly secured to spin dle 18 by feed roll 19. .Gear wheel 5,8 meshes with a gear `wheel 59 of corresponding size keyed to a shaft 60. The gear wheels 57 and 59 rotate in ra counter-clockwise direction, and through indirect connections intermittently operate feed rolls 1.6 and 17 respectively to rotate in a clockwise direction.

Referring now to Figure 1, toothed quadrants 61 and 62 are respectively rigidly secured to shafts 56 and 60, and their radiiV conform with the gea- r wheels 57 and 59. These quadrants are set with their middle lines approximately 180o apart and in rotating with the shafts 56 and 60 they abut a ing assumed that the diameter of movable pair of elongated teeth 63 and 64 0f toothed* for the quadrants and pinions so thatthe pinions are given one complete revolution by the quadrants in the rotation 0f the gea-r wheels 57 and159. The elongated `teeth are yieldingly engaged by detente in spring latch bars 67, as shown in Figures l and 2, the latch bars being secured-to the side wall 15 of the casing and sloped toward the iin.- l gers 63 and 64 so that the quadrants in rotating may pass over the inner faces of the latch hars to abut and disengage the teeth 63 and 64 therefrom. The idler 58 is ,prol vided with a cranky pin 68 to which is connected one end of a connecting rod 69 that operates a crossv head 7 0 slidab'le on guide bars. 71 `disposed on op Vosite sides of lock shaft-.33, ofthe rocking fjraine andarranged upon the outer face of partition 14. A retractile spring l72 is connected at one end to a stud 73 carried byl one ofthe side bars 32 of the rockingl frame and extending through a curved slot 7 4 in the partition 14. The.

opposite end yof spring 72 is secured to cross head :pin 75. The spring 72 is tensioned by the movement .of cross .head 7 0 and operates to impart an abruptrocking motion to the rocking frame.A i l Inthe operation ofthe device, the continuous rotation vof* gear wheel 58 operates the cross head kto move beyond a horizontal line lextending through the studf73 and the center .of the cross head. As the cross head recedes from this line, spring 72 is progressively tensioned until sufficient energy is had to rockthe frame.' In Figurev 7 the parts are shown in the positions they occupy just prior .to moving into the positions shown in Figure 1. That is to say, the connecting rod.

69 is at the lower end of its stroke `and ,the left hand yedge of quadrant 62 is adjacent to finger 64. Quadrant 62 next turns'pinion 66 which operates feed vroll 17 to turn at a relatively high speed and complete one revolution by the time that quadrant 62 occupies the position shown in Figure l. In this action of the parts, it will be noted that latch 67 engages with tooth 63 so that feed roll 17 in turning displaces. six inches of record from loop d and `during this expenditure the record draws `the floating support forloop (Z downwardly in Figure 7 and at the same floating support to the position shown by dotted lines in Figure 1. During this time upward movement o n the part of cross head 70 kis lstoring energy vin spring .7 2 which operates to rock the frame at substantially the same time as the loops and d of Figure 7 assume the positions shown in Figure 1.

Whenthe rocking :trame responds to the action of spring 72 the movement will be decidedly abrupt and iexble elements 28 and 34 on the right of Figures 1 and 7 will shift the carriage to the right of opening 5 in Figures 1 and 7. At this time quadrant 61 moves into contact with finger 68 and imparts one revolution to feed roll 16 to withdraw the record from the section between thecarriage and the said roll 16. The withdrawal of this section ot the record shortens loop b and lengthens loop c, the length of loop b now being the same as shown in Figure 7 but disposed on the opposite side of opening 5. During the action last described on the part-of the record, cross head 7O'isl movingdownwardly and when quadrant 61 movesaway from pinion 65, the energy ot spring 7 2 operates to rock the frame and restore the carriage to t-he position shown in FiOfure 7. The surface area of loo Z) in the b. j.. position shown in Figure t corresponds with the area of one picture so that in moving from the left to the right of opening 5, the

picture contained in the loop is substituted for the picture within opening 5, and the latter then becomes the picture within the loop when the parts are positioned as shownl in Figure 7. lVhen loop I) is elongated as shown in Figure 1, it contains three pictures and of these the uppermost on the lett of loop b is substituted for the picture previously displayed in the movement ofthe carriage to the right and the picture displayed becomes uppermost on the .right side of the loop at the end of the movementof the carriage to the right. When loopv b shortens, the first picture displayed and the succeeding picture are withdrawn and advanced to the right, and that which was previously the intervening picture is then through the opening 5. In this action of the parts, it will be noted that the pictures are not exhibited in the order of their arrange# ment on the sheet, but the sheet, nevertheless, advances with a step by step motion to the right, as indicated by the arrowsin Figure 7. It will be further noted that the quickmoveinent of the carriage and the peculiar displacement and substitution of the several pictures readily conveys -the'limpression of continuity and apparent superimposition is eiiected without the employment' of a shutter. It will, ofcourse, be understood that iiieffecting apparent continuity in the pictures exhibited, their arrangement upon lthe record sheet `will be such as will conformv to the order in which they are displayed.

Although I have shown and described one embodiment of my invention, it is1tobe understood that the saine is susceptible .of

various changes, and I reserve the right to exhibited.
