Patented Aug. 11, 1931 UNITED STATES HARLOW M. DAVIS, 01F BUFFALO, NEW YORK ADVERTISING DEVICE Application filed November .20, 1929. Serial No. .40 8;479.

v This invention relates to advertising devices of'that character in which a series of cards or mats bearing advertising or other matter are successively exposed to view for 6 a predetermined length of time, the construction being such that two cards or mats are displayed 'at a time and the object of the invention is to provide a simplified construction in devices of this character and 'to provide a metal or like casing having a removable front panel provided with acentrai aperture throughwhich the cards in the casing are displayed to view, the provision of a removable front panel permitting a. ready change in form of the device to conform in design to anyparticular character of window display and may be made of cheap cardboard readily permitting any artistic design to be printed or painted thereon also in conformity with the character of goods being advertised and in association with the goods in the store windowor other display space.

' The device is similar in general character 2 to that shown in the U. S. patent to Albert K. Davis, No. 1,540,830, issued June 9, 1925, and a feature of this construction, in addition to that above mentioned,is in the provision of a driving motor in the base of the case and a construction permitting a reduced length of chain mechanism and linkage through and by means of which the cards are moved from one position to another and h an arrangement of parts to/sec'ure practicallynoiseless operation.

An additional feature is involved in't'he manner of mounting the drive motor whereby the vibration of the motoris not transmitted to the casing. With a metal casing and the motor rigidly attached thereto, the casing becomes a sound box whereby vibration of the motor becomes detrimental to use of the device through the resultant noise.

Additional features and objects of the invention reside in the specific details of construction of the driving mechanism and connection of a'transfer frame therewith by and through ."which the cards are moved from and to display position all is'he'reinafter more fully described. These and other objects and'novel features ofthe invention are hereinafter more specifically set forth, and the preferred form of construction of a device embodying my invention is shown in the accompanying drawings in which Fig. 1 is a diagrammatic front elevation of my improved advertising device.

In previous constructions, such for instance as shown in the .U. S. Patent No. 1,5f0j'880 above mentioned, the motor is mounted in the upper part of the case and several pulleys arenecessarily utilized to secure the required slow speed of movement of the transfer device and a considerable length of chain and intervening mechanism. By. placing the motor 1 in the lower part of the casing 2, it is positioned closelyadj'acent to the drive shaft 3 by which the transfer mechanism is operated. This shaft 3 is mounted in a casing 4 and has a worm 5 thereon, shown in dotted lines in Fig. 9

meshing with a worm wheel 6 1n the casing The worm wheel is provided with a shaft 7 extending through the casing 4 and a vertical channel member 8 in the channel on which is positioned a sprocket 9. The shaft 3, as shown in Fig. 5, has a pulley 1O thereon and the shaft of the motor has a pulley 11 thereon, the two pulleys being connected by a yieldable belt 12 preferably of rubber.

The motor is formed with a base 13 which is supported on a spring metal strip 14 looped as at 15 and 16 at its opposite ends and having a portion 17 extending parallel with the part 14 and directly therebeneath by means of which it is secured to the floor of the casing. Preferably a metal plate 18 is positioned on the upper face of the portion 17 of the suspension device and a rubber or other pad 19 between the said member 14 and the bottom of the case. The motor is provided with the usual circuit wires enclosed in the conduit 20 leading to a block 21 having a fuse plug 22 and from there to the exterior of the case for connection with an energizing circuit. The sprocket 9 is adjacent the bottom of the vertical channel member or standard 8 and about midway the height of the casing and length of the channel is an idler sprocket 23 supported by the channel member. A sprocket chain 24 extends about the two sprockets. The channel 8 is secured in place at its upper and lower ends by means of similar brackets 25 havin respectively upwardly and downwardly extending flanges to receive a bolt or bolts 26 extending through the base of the channel 8 and this portion of the brackthe channel 8, as will be seen more clearly in Fig. 6, and between the flanges of the member 31 and the flanges of the channel 8 and also between the base portions of these two members is provided a strip of felt or other desirable material indicated at 32 to prevent a metal to metal contact at this point and thus secure silence in operation which is one of the features of my improved construction. The transfer frame 30, as may be seen in Fig. 6, has a rearwardly extending or ofi'set part 33 attached directly to the member 31 adjacent its upper edge and a yoke 34 of U form has the end portions thereof secured to this part 33 and extends 3 about the channel 8 out of contact therewith.

A pitman 35 is pivoted at one end to the center of the yoke at the rear side as will be understood from Fig. 6 and the opposite end is'pivoted to a link of the chain as will be understood from Fig. 5. Thus, by rotation of the sprockets and the chain thereon the transfer device is moved upwardly and thence downwardly as the point of connection of the pitman 35 with the chain passes from one side to the other of the pulleys. By this arrangement I am enabled to materially reduce the length of the chain and to reduce the size of the apparatus correspondingly and yet secure the necessary movement of the transfer device in moving the cards as is hereinafter described.

The transfer device is similar in general respects than that shown in the said Patent No. 1,540,830, it being formed with U-shaped end yokes 36 and 37 and the

inbent ends

38 and 39 respectively of the transfer frame carry a catches 40 and 41 which are pivoted at 43 to a part struck out from the

respective members

38 and 39 as will be understood from Fig. 11. These catches 40 and 41 have a curved forwardly inclined upper face 44,

as shown at the left of Fig. 7, and a depending part 45 providing a construction tending to hold the pivoted members in the position shown but permitting the members 40 and 41 to tilt on engagement of the forwardly projecting portion 46 thereof with any fixed part ashereinafter shown. At the rear of the frame practically directly opposite the catches 40 and 41 are the

pivoted latches

47 and 48 which are likewise pivotally sup-' ported on a part struck up from the frame, each having a downwardly extending part tending to hold these latches in the position shown in Fig.7 and permitting the latches to be turned with the lower ends inwardly upon the upper curved end 49 thereof engaging a stationary element. The upper face 50 of each of these last named latch members normally lies in angular relation to the frame as shown.

The transfer frame has attached to the rear side thereof the inwardly projecting reversely bent fingers 51 and 52 near each

latch member

48 and 49 respectively. These fingers, as will be seen more clearly in Figs. 9 and 10, are forwardly and then rearwardly inclined.

The opposite sides of the casing 2 have attached thereto the respective vertical bars 53 and 54, the edges of which are return bent to provide a rounded smooth edge portion avoiding necessity of finishing the same and the yoke ends 36 and 37 of the transfer frame extend between the side walls of the casing and each of these bars 53 and 54, as shown more clearly in Fig. 6. The transfer frame 30 at the points opposite one edge of the members 53 and 54 is provided with a felt or other contact memfill nemesis:

forward edge of the vertical bars 53 and 54 sothat there is no possibility of metal contact at that point with the vertical bars.

The cards or mats here shown are formed 4 of a frame consisting of the horizontal upper part 57 havingthegrounded ends 58 and 59 and aU'shaped frame 60has the upper ends of the legs thereof secured to this cross bar 57.

As will be seen in Fig. 3, this upper cross member 57 is formed with a slot 61 and it is to be understood that the U frame 60 is of channel form and so attached to the member 57 as to permit introduction of a card through the slot 60 and into the channels of the U member, the construction thus permitting ready removal or insertion of cards. The side bars 53 and 54 have an upper raceway 62 on opposite sides of the casing, as shown in Fig. 5, and a lower raceway 63 also on opposite sides as shown in Fig. 5. The lower raceways each have a curved uvper face 64 and the forward point thereof extends forwardly beyond the forward point of the upper raceway 62. This arrangement provides that the

rounded end portions

58 and 59 of the frame lying on this inclined surface 64 tend to move by gravity toward the rear of the raceway. At the rear the lraceways 63 have an upwardly extending portion 65 providing a stop. The upper raceways at the forward end are provided with a similar stop 66 determining the position of the forward card of the upper bank and the upper face 67 of the raceways 62 are forwardly inclined to cause the cards to move forwardly on this incline. The rear end of each raceway 62 is provided with a.

pivoted latch 68 having a straight upper face somewhat more sharply inclined to the horizontal than the face 67 of the raceway and projecting to the rear thereof in such manner that'the weight of this rearwardly projecting portion is sufiicient to normally .i 1 position the latch as shown in Fig. 9.

To limit the movement of the latch on its pivotI provide a slot 69 in the rear portion of the raceway and the latch is provided with an inturned lug 70 riding in this slot which gwill permit the latch to move upwardly from the position shown'in Fig. 9. It will thus be seen that the cards are arranged in two banks in superimposed relation and the reciprocating transfer member takes the rear card from the lower bank on the lower raceways and deposits the same at the rear of the cards on the upper raceways and in so doing removes a card from the front of the upper raceways and deposits it on the lower raceways at the front thereof. Thus,

each card is in view part of the time at the front of the bank on the upper raceway and for a similar period of time at the front of the bank of the lower raceway.

The operation of the transfer device is as follows: WVith the parts in the position shown in Fig. 9 and upward movement of the transfer device 30 in the direction of the arrow shown in the said figure, the

latch members

48 and 49 at the rear of the transfer device move upwardly between the raceways 68 and the supportings bars .53 and '54 on opposite sides of the casing and engage the ends 581and 59 of the card frame extending into said space. As the transfer device and

latch members

48 and 49 come to (am gagement with these rounded ends of the card frame, the said frame slides down the inclined face 50 of the latch members, as will be understood from Fig. 10.

As the movement upwardly of the transfer device continues above the position shown in Fig. 10, these rounded. ends 58 and 59 strike therespective latches '68 moving the same upwardly permitting these ends of the bar 57' to pass above the latch which immediately drops forwardly due to its construction heretofore described and into the path of movement of the bar ends on downward movement of the transfer device. This movement therefore discharges the frame and advertising matter or device carried thereby to the rear side of the upper bank it moving downwardly on the inclined face 67 of the raceways 62. On this upward movement of the transfer device, the front latch members 40 and'4l alsopick up the forward card of the upper bank due to the fact that the front portion 46 is of sufiici'ent length to engage the rounded ends of the frame 57 of the front card. The transfer devicerises to such point that the catch 40 carries the forward frame 57 of the upper bank above the stop 66 ofthe raceways 62 and thereupon this frame rides toward the front on the forwardly curved upper face of the catch 40 as indicated in dotted lines in Fig. 10. Thus, as this forward frame of the upper bank is lifted from its position on the raceways 62 and moved forwardly beyond the end of the stop 66, the downward movement of the transfer device carries the removed card frame downwardly on its reverse movement and finally deposits the same on the front projecting end of the raceways 63 for the lower bank.

It will be noted also that, the transfer depivoted. This permits these members on downward movement of the transfer device (at which time there is no frame carried by these latches) to pass downwardly below the rear frame 57 of the lower bank. In passing this frame the forward rounded end 49 of the

latch members

47 and 48, on striking the extended ends of the frame 57 merely turn backwardly and then again turn forwardly to the position shown in Fig. 9 so that upon succeeding upward movement the rearmost frame is raised from position and carried upwardly as before stated.

The fingers 51 and 52 extend forwardly to such position that, as a frame 57 is deposited upon the upper raceways and catch members thereof, following downward movement of the transfer device, the deposited frame, if not moved by gravity, is pushed forwardly on the raceway.

Its delivery from the transfer device to the raceway and its movement downwardly is thus insured. Thus through reciprocation of the transfer device a card is moved from the rear of the lower bank and deposited at the rear of the upper bank on the upward movement and on the downward movement a card is likewise removed from the front of the upper bank and deposited at the front of the lower bank. These two front cards are displayed to view through an opening 7 O in the removable front plate 71 of the casing. The casing is preferably of sheet metal and has the rear wall 27 and end walls 27a and 27b and at the front side has vertical

marginal portions

72 and 73 which, as shown in Fig. 2, have return bent edges 7st and 7 in spaced relation with the body thereof providing vertical grooves. The front plate or panel 71 may be of cardboard as heretofore stated and therefore is inexpensive material and may be shaped in any desired manner to conform to the character of decoration of any display and the face thereof may be painted or printed and arranged to support various articles being advertised by this device. To enable changes to be made daily or more often if desired, this plate is made removable. For this purpose the rcar face of the plate has secured thereto a sheet metal return bent clip 76 and 77 adapted to fit into the vertical grooves formed by the return bent ends 74 and 75 of the casing. This arrangement of the parts is shown in Fig. 2 in plan view from which it will be understood that the front panel or plate may be removed by pulling upwardly thereon and a new and differently designed front panel substituted therefor.

It is believed evident from the foregoing that the device is comparatively simple and inexpensive in construction and well adapted for the purpose stated; that it embodies several new and unique features namely, the construction of the relatively movable parts to avoid any metal to metal contact whereby the sliding of one part on another is practically noiseless, the mounting of the electric motor in such manner and the drive mechanismof such character that the vibration of the motor is not transmitted to the casing, that thedriving gear, by means of which the chain is operated in movement of the transfer device, are enclosed in a case or housing attached to the lower end of the vertical guide member or channel 8 which permits the gears to be packed with grease, and that in the formation of the vertical guide member of channel form with the open side facing to the rear of the cabinet the chain and sprockets and such parts are so separated from the banks of cards that grease or oil carried by the chain is not liable to be spattered or thrown onto the cards, and that by the arrangement of parts, particularly the drive mechanism etc., in the bottom and the pitman connection of the transfer frame to the chain provides a compact structure avoiding excessive height of casing, and that the various objects of the invention are attained by the construction described.
