This invention relates to a display apparatus or machine whereby a plurality of displays, such as curtains or sign sheets, posters and the like, containing advertising or other intelligence matter, are severally and successively displayed and each for a predetermined period of time.
More particularly, the invention relates to a display apparatus or machine of the character disclosed in United States Patents No. 2,190,426 of February 13, 1940, No. 2,195,249 of March 26, 1940, and No. 2,410,975 of November 12, 1946, granted to me.
The principal object of the invention is the provision of an apparatus or machine of the indicated character which embodies improvements whereby advantages are attained, among which are the following. It facilitates installation, replacement and repair of parts. Electrical mechanism for controlling the lighting and for operating the sign units are conveniently accessible and are so assembled and arranged as to meet underwriters requirements. The sign units or displays are transferred noiselessly. The sign curtains, sheets or posters are displayed without liability of being torn or mutilated and are kept flat and even when displayed. The driving mechanism is conveniently housed so that oil and dirt are prevented from reaching the sign curtains, sheets or posters.
With the foregoing, other objects of the invention will appear when the following specification is read in conjunction with the accompanying drawings, in which Fig. l is a vertical sectional view of an appa ratus embodying the features of the invention, the section being taken approximately on the line l-l of Fig. 2.

Fig. 12'is an enlarged sectional view of the clutch of the driving mechanism.
Fig. 13 is a side view looking at the clutch in the direction indicated by the arrow l3 of Fig. 12.
Referring now to Figs. 1, 2 and 3, it will be apparent the apparatus or machine includes a substantially rectangular casing, housing or cabinet Ill consisting of side walls ll, top wall 12, bottom wall M, back wall l5 and front wall It having a sight or window opening ll.
"Each of the side walls I I has a removable panel l8. The side, top, bottom and back walls are connected to each other by any suitable means. The front wal1 I6 is removably held in place by small slotted brackets ill on the wall I6 which engage pins 20 on the side walls II, as shown in 5 Fig. 2. A horizontal partition or separator 2| is interposed between the side walls and spaced a short distance above the bottom wall to provide a compartment for parts of the driving mechanism and electrical equipment to prevent oil and dirt from reaching other parts of the apparatus. The back wall has openings therein at the top and bottom and the partition 2| also has openings therein. The openings are designated 22. Strips 23 are attached to the back wall l5 on the outside thereof for the purpose of keeping the apparatus spaced from any flat surface. It will be apparent air may pass from a point at the bottom of the cabinet upwardly through and out of the same at the top, thereby giving a complete air circulation throughout the interior of the apparatus.
Each of the side walls II has a continuous groove or track formed therein at the inside thereof to provide a closed loop guideway 30. Each guideway consists of two vertical straight runs 3| and 32, respectively, joined by a lower semi-circular run 33 and an upper run34 consisting of turns or bends 35 merging into the upper ends respectively of; the runs 3| and an intermediate straight portion 36 in continuation of the turns 35. The side walls I I may bemade of wood or other suitablematerial and the guideways 30 are formed directly therein instead of using an additional frame structure to simplify the com SPIu tion.
The guideways 30 serve for guiding a plurality respectively of the carrier 4| of the next precedof similar sign units 40 along a prescribed path ing sign unit. It is therefore understood as one for the intended purposes. It is to be understood sign member 43 of one unit is being unrolled for that any suitable number of units 40 may be used. display prior to the upward travel of the unit, a In Figs. 1 and 4 of the drawings only a sufficient 5 preceding sign member d3 of a second unit is number of the units 40 are shown to make the being rerolled as the second unit travels upwardly operation clear and so as to expose other parts as shown in Fig. 4. of the machine. The units 46 are identical in Pick-up means is provided for moving the units construction and operation. Therefore; a de- Ml'upwardly meet a time. Said means includes scription of one willsufiice for all. A unit lfla shaft 60' supported for rotation by adjustable consists of a carrier 4! and a spring roller 42 on brackets El on the side walls II, respectively, near which is wound or rolled and from which is un=- the top of the cabinet. Another shaft 62 is supwound or unrolled a sign membewposter; curtain: ported-for rotation by" suitable bearings 63 on the or sheet 43.

The upper end of each bar is connected with one end of a contractile spring 85 whose opposite end is connected with a securing element 86 on the adjacent side wall I I. The lower ends of the bars 84 are rounded to provide cams 81 which cooperate with the bumpers 52, to not only hold each sign unit presented thereto while it is stationary, but also to move said bars 84 to a releasing position as the unit is moved upwardly by the pick-up means. The springs 85 return the bars 84 to their functioning position. The lower ends of the bars 84 terminate above the lower ends of the levers 80 a distance to insure the temporary retention of each unit .40 in a position for the pick-up operation by the lugs 66. As each unit 4Il reaches its up position it causes a release of a unit in the advance ends of the runs 33, by reason of the operation of the parts I0, 83 and 89. There is a lever 80 and a bar 84 in proximity to each other at each side of the cabinet. A resilient stop 8 serves as a bumper for the associated lever and bar to I noiselessly limit the movement thereof to the functioning position.
In order to retain the sign member 43 of each unit smooth and in parallelism with the front wall there are provided spaced parallel slats 90, each pivotally connected as at 9I with radius arms 92 pivotally connected as at 93 with brackets 94, respectively, on the adjacent side wall II, as shown in Fig. 1. A dash-pot 95 is connected with the arms 92 between the same. The dashpot consists of a rod 96 having one end pivotally connected with one arm 92 and the other end of the rod has a plunger 91 which operates in a cylinder 99 pivotally connected with the other arm 92. A check valve 99 controls the flow of air into and out of the cylinder 98. The lower ends of the slats 90 are rounded so that the bumpers 52 will cause the slats to move rearwardly and upwards as the sign unit moves upwardly. The slats return by gravity action after the unit reaches its up position to gently press against the unrolled sign member being displayed. ,The dash-pots control the movement of the slats, and prevent any sudden or jerky motion of the slats and connected parts. Stop pins 88 on the walls I I, respectively, prevent the slats from moving too far on the return, engaging the lower arms 92.
It is to be noted the sign units 40 move downwardly by gravity at the back of the cabinet and push one unit at a time into position to be picked I up every time a unit is delivered to the backcheck means. In order to prevent a sudden or quick movement there are provided latches I00 which cooperate with the bumpers 52, respectively, of each unit 49. Each latch I00 has a cam IOI on its lower end while the upper end has connected therewith one end of a contractile spring I02 whose opposite end is connected with a securing element I03 on the adjacent side wall I I, The latches I00 sustain a portion of the weight of the units 40 above the same in the runs 32 of the guideways. The delivery of a unit 4I'I into the upper runs 34 pushes the whole series of units 40 so that there is always one in position ready to be picked up.
The driving power is derived by the use of an electric motor IIO mounted on a base III having rubber cushions II2 resting on the bottom wall I4 near the right side of the cabinet. A gear box H3 is also mounted on the base III and this box contains reduction gearing, generally designated H4, and including a'power input shaft H5 and a power output shaft H6. See Fig. 11. A clutch H1 is connected with the shaft H5. The clutch consistsof apulley II8 loose on the shaft II 5 and a disk II9 fast on said shaft. The pulley H8 is held against axial movement by collars I20 fast on the shaft I I5 as shown in Fig. 12. The pulley I I8 carries pivoted brake members I2I each having a roller I22. The members I2I are under the influence of tension springs I23 connected with lateral rods I24 on said members I2I as shown most clearly in Fig. '13. The brake members |2I cooperate with the disk II9 which has depressions I25 in the periphery thereof. Under normal action the rollers I22 are disposed in the depressions I25 respectively and effect the required normal power torque. A belt I26 encircles the pulley I I 8 and a pulley I2'I on the motor shaft I28. Any overload or stall for any reason will cause the clutch to slip since the rollers I20 will ride out of the depressions and move around on the disk I I9. This will prevent damage to the parts and also prevent the motor from burning out. A driving chain I29 encircles a sprocket I30 fast to the shaft H6 and a sprocket I3I fast to the shaft 62. Thus rotary motion is transmitted from the motor IIO to the shaft 62 through the intervention of the parts I'I4I 3 I. The sprockets I30 and I3I, as well as the chain I29, are disposed between the panel I8 and the right hand side wall II. This panel I8 may be removed to afford access to the said chain I 29 and the sprockets I30 and I3I, A bolt and nuts I32 connect the box II3 with the base III for adjustment to keep the chain I29 under proper tension.
Spaced vertical plates I33 carried by supports I34 extending from the. side walls II have arranged thereon certain electrical appurtenances including lighting elements such as the fluorescent tubes I35 backed by a reflector for lighting the sign members 43. Also a junction-box I36 is arranged on the left-hand side wall I I. This box I36 supports two terminals from the lighting circuit, two terminals from the motor circuit, two terminals for the line and two terminals for a fuse, all properly electrically connected with two control switches for the lighting and motor circuits. Access to these parts is afforded by the removal of th left-hand panel I 8. .An'extension cord I31 for supplying a suitable source of voltage is provided, This cord may be drawn into the cabinet below the partition 2| and thus be protected during shipment of a machine. The, cord may be withdrawn readily when the machine is to be put into operation. All electrical appurtenances are installed to pass the requirements of underwriters.
It is to be understood that changes in the details of construction and arrangement of the parts may be resorted to without departing from the spirit of the invention as expressed in the appended claims.
