Each ‘bolster 40 carries 'I---‘Iv of Fig. 6. ~ 2,410,975 3 .4 a pair of guide rollers 4|, and has a lug 42 ex tending radially with respect to the axis of the shaft 39. Thus there are two lugs 42 for each carrier 36 and the purpose thereof will be ex plained hereinafter. The roller 31 is of the shade roller type but without a ratchet and its spring so that in timed accord the lugs 64 will engage the carrier portions respectively of a sign unit 35 and cause the latter to move upwardly of the casing I9 at the window l6 as indicated in Figs. 2 and 3. This operation is repeated on each sign unit 35. The shelves l1 and I9 have openings to pass the chains and their lugs. , . _, 43 serves for rewinding or rerolling the sign mem ber thereon and is put under tension when the In order to cause the display of the sign mem sign member is unwound. The sign member in ber or sheet_38 of each unit 35 by unrolling the the form of a curtain, web or’sheet may be made 10 member, prior to the upward travel of the unit, of any suitable translucent material, such for the member or sheet 38 has a pull-rod 65 extend instance, as stout paper, cloth, or other ?exible ing through a tunnel on the outer end thereof. sheet material on which may be imprinted or The opposite ends of the rod 65 are threaded as otherwise applied advertising matter of various at 66 and each of said ends carries a thumb nut kinds. The roller 31 is held against axial move-, 15 61 or the like. The ends of the pull-rod 65 are ment by the bolsters 49 each of which provides a received in notches 68 respectively of the lugs 42 cylindrical portion 44. of the carrier 36 of the next preceding sign unit. The sign units 35 have guided movement by The nuts 61 When tightened against the lugs 42 virtue of a closed loop guideway 45 on each of hold the rod 65 in place and the related sign the side plates | l. Each guide way is formed by 20 member 38 connected for the unwinding or re spaced parallel ?anges 46 integral with its plate winding operation as may be the case. See Figs. II to provide traction surfaces for the rollers 4|. 6 and 7. ' The guideway consists of two straight runs 41 Attention is called to the fact that the provision and 48 respectively joined by semi-circular ends of the lugs 42, pull-rod 65 and nuts 61 for each 49 and 59 respectively.

A unit 35 may be replaced in a reverse the front straight run 41, there is provided means manner. as follows. A worm 5| fast on the shaft 23 As each unit 35 is brought to its up position meshes with a gear 52 fast on a stub shaft 53 35 it is temporarily held therein for a predetermined supported for rotation by a bearing 54 secured to period of time by a back-check means at each side and depending from the shelf l9, there being a of the opening l6. Said means consists of a pawl collar 55 on the upper end of the shaft 53, which or check member 69 pivotally mounted on the in conjunction with the gear 52, hold the shaft shaft 6| and kept in operative position by a collar 53 in place. A bevel gear 56 fast on the lower 40 10 ?xed on the shaft and the adjacent sprocket end of the shaft 52 meshes with a larger bevel 62. A contractile coil spring ‘H has one end con gear 57 fast on a shaft 58 horizontally disposed below the shaft 23. The opposite ends of the shaft 58 are journalled in bearings on the side plates II respectively. The shaft 58 has its axis 45 disposed coincident with the center from which _ the semi-circular portion of the guideway is struck. A pair of similar disks 59 are fast on the shaft 58 in proximity to the plates ll. Each of the disks has a plurality of notches 66 in the 50 periphery thereof, there being ten notches 60 in the present instance in keeping with the size and number of the sign units 35 used. The notches 69 in the disks 59 cooperate with the portions 44 of the carriers 36 as the units 35 are presented by gravity one at a time from the guideway run 46 and transfer the units 35 to a point where 55 they are picked up one at a time by means pres ently to be described. ' The pick-up means comprises a shaft 6! ‘ad 60 justably mounted on the shelf | ‘I aboveLthe same v by means similar to that which supports the shaft 23; therefore, similar reference numerals will be applied to corresponding parts. The lugs nected with the lower end of the pawl 69, as at 12, and the opposite end connected with a set screw 13' carried by a lug on the shelf [1. An upstand ing stop 14 on the shelf |'| limits the movement of the pawl 69 against the action of the spring ‘II to its checking position as shown most clearly in Fig. 5. The pawls or check members 69 coop erate with the carrier portions 44 respectively of each unit 35. As the unit moves upwardly the portions 44 cam the pawls 69 against the action of the springs ‘II to clear the same, after which, under the reaction of the springs, the upper ends of the pawls reengage the portions 44, thereby checking the unit in the up position just as the lugs 64 clear the same. As each of the units 35 reaches its up position it crowds the preceding units by reason of the contact of the guide rollers 4|._ This causes the units to traverse the upper curved ends 49 under power transmitted by the chains 63 and their lugs 64 until the units 35 reach the down sides of said ends 49, whereupon the units drop by gravity into 24 and parts 21 applied to shaft 6| are the reverse 65 the vertical runs 48 of the guideways. From the foregoing, it will be obvious that the of the ones applied to the shaft 23. Sprockets slow rotation of the disks 59 causes the units 35 62 are fast on the shafts 23 and 6| and they are to be presented successively one at a time to the arranged in pairs, there being one pair at each lugs 64 which move each unit upwardly until en side of the sight opening l6 and in proximity to gaged by the back-check means 69. As a unit the guideways 45. A chain 63 encircles the sprockets 62 of each pair. Each chain 63 has a special link which is provided with a lug or abut ment 64 having an anti-friction roller, as shown in Figs. 2, 3 and 5. In each cycle of the chains 63 the disks 59 move one-tenth of a revolution, 70 35 is retained in its up position by the means 69, a second unit is being moved upwardly by the lugs 64, a third .unit will be held in its down posi tion by the‘ disks 59 all directly behind the sight opening I6a's indicatedin Fig. 3. Consequently, the sign member 38 of said second unit willibe 2,410,975 rewound as the sign member 38 of said third. unit is being unwound. Thus one sign member is be outer end to detachably engage the last men ing rewound as one is being unwound, and this action takes place after a sign member has been displayed for a predetermined period of time. Attention is called to the fact that by adjust ably mounting the shafts 23 and BI, the chains 63 will be kept adjusted to bring their lugs 64 around at the proper time and so keep the units tioned sheet withsaid lugs, said means consist ing of a pull rod on said outer end of the indi cated sign sheet, the opposite ends of said rod being threaded, clamping nuts on the threaded rod ends respectively, said lugs having provision to‘ receive the rod ends respectively, and said nuts being clampingly engageable with said lugs. 3.
