AUTOMATIC ADVERTISING DEVICE.

SiPEQIE'ICATION forming part of Letters Patent No. 319,597, dated June 9, 1885.

Application filed May 3, 1884.

To all whom it may concern.-

Be it known that I, JOHN MOGREER,a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Automatic Advertising Devices, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My present invention has for its object to provide an improved construction of advertising device, whereby a series of pictures or other attractive cards may be successively and automatically displayed in connection with advertisements to which the attention of the public will thus be directed. This object I have accomplished by the mechanism hereinafter described ,and illustrated in the accompanying drawings, the invention consisting in certain details of construction, to be particularly defined in the claims at the end of the specification.

Figure 1 is a view in front elevation of my improved advertising device,parts being broken away for the purpose of better illustration. Fig. 2 is a side view with parts broken away. Fig. 3 is an enlarged detail view, in longitudinal section,of the display-drum and connected parts. Fig. 4 is a sectional view on line 09 w of Fig. 3. Fig. 5 is a transverse sectional view of the drum, aportion of one end being broken away to show subjacent parts. Fig. 6 is a detail view, in transverse section, of one of the cards and its sustaining-rod.

Like letters of reference denote corresponding parts in the several views of the drawings.

A designates the main casing, the front A of which is cut away, as shown, to form an opening through which the cards may be seen. Within this casing, at a point about opposite the center of the front opening, is placed the display-drum B,that is sustained by means of the shaft G,having its ends journa1ed,respectively,in one side of the casing and in the journal-block 0, attached to opposite side. The

drum 13 consists, preferably,of a paper cylinder having its exterior suitably ornamented, and having the heads b, to which are attached the plates D D, that project beyond the periphery of the drum, and are provided with (No model.)

the perforations d, to receive the rods E, that enter the pockets formed by the strips f, at

- tached to the cards F, and thus serve to hold the cards securely upon the drum. Perforat-ions d are also formed in the end of the plate D, to receive staples d, that fit over the bent ends of the rods and retain them in place. From this construction it will be seen that in order to secure the cards upon the drum it is only necessary to withdraw the staples d and slip backward the rods until out of the plate D,when their free ends may be thrown outward, and the cards may be placed thereon.

Each of the cards F is provided,preferably, upon one side with a picture to attract the eye, and upon the opposite side with an advertisement, so that as the drum revolves the card will successively display the picture and the advertisement.

Upon the side of the plate D is pivotally held the pawl 9, that is pressed downward by the spring 9, and engages with the ratchetwheel G, attached to the end of the cord-pulley H, that iskeyed to the shaft C.

To the opposite end of the pulley H is connected the ratchet-whecl H, with which engages the pawl I, that is carried by the main cog-wheel l, loosely journaled on the shaft 0, and held in place by means of the washer i. A pinion, K, the shaft of which is journaled in the frame 7a ,engages with the cog-wheel I, and to the shaft of this pinion is keyed the escapement ratchet-wheel L, the movement of which is controlled by a suitable double escapement-pawl carried by the upper end of the weighted pendulum-rod L.

A cord, M, having one end secured to the cord-pulley H, passes through the top of the casing over the pulley N, and sustains the weight O,that serves to impart the movement to the display-drum necessary to bring the cards before the opening of the casing.

Upon the end of the shaft 0 farthest from the escapement mechanism is placed the ratchet-wheel P, that is connected to the plate D, this ratchet wheel and drum being loosely journaled on the shaft 0, and a pawl, 1?, piv otally connected by the screw 1) to the side of the casing,engages with this ratchet and serves to prevent any backward movement of the drum. The cards F are made of such size that as the drum revolves each card will successively strike the top of the front opening, and will be detained thereby, thus showing the picture until the, drum has traveled a sufficient distance to permit it to drop and display the advertisement upon the reverse side.

From the foregoing description the operation will be seen to be as follows: A crankkey is applied to the squared end of the main shaft, and by turning this key the weight-cord is wound upon the cord-pulley H. During this operation the ratchet-wheel P and pawl P prevent the backward movement of the drum. The force of the weight,when wound up, tends to turn the cord-pulley,whieh communiea'tes motion to the drum by the ratchetwheel G and the pawl'g. The ratchet-wheel H, engaging with the pawl I, turns the cog: wheel I; but the movement of the cog-wheel, and consequently of the cord-pulley and drum, is-controlled by the double pawl of the pendulumand by the escapement ratchet-wheel and pinion. It will thus be seenthat the displaydrum is caused to slowly revolve to bring the cards before the front opening of the casing.

I am aware that it has been heretofore proposed to construct an automatic advertising Having thus described my invention, what I claim as new,and desire to secure by Letters Patent, is

1. In an advertising device, the combina- 5 tion, with the inclosing-case having a sightopening, and with the display-drum having the perforated end plates projecting beyond its periphery,of rods passing through said end plates and removably held therein, substano tially as described.

2. In an advertising device, the combination, with the display-drum,of the perforated end plates,-the rods removably held in said end plates,and the cards having each apocket 5 to receive a rod, substantially as described.

' 3. In an advertising device, the combination, with the drum having the perforated end plates projecting beyond its periphery,of the removable rods having bent ends and staples 50 for holding said ends, substantially as described. I

4. In an advertising device, the combination of the drum B, the shaft 0, the ratchetwheel P, the pawl P, the ratchet-wheel Gand 5 pawl g, the cord-pulley H, the cord M, the weight O,and the escapement mechanism,sub stantially as described.
