' ApsTAPPoR-u I ADVERTISING EXHIBITOR AND PHONOGRAPHIG ANNU-N'G I-ATOR. APPLICATION FILED MAY16, 1910.

WITNESSES: INVENTOR GEORGE A. STAFFORD, OF BELGHERVILLE, TEXAS.

ADVERTISING-EXHIB ITOR AND PHONOGRAPHIC ANNUNCIATOR.

Specification of Letters Patent.

Application filed May 16, 1910. Serial No. 561,564.

To all whom it may concern:

Be it known that I, Grouse A. STAFFORD, a citizen of the United States, residing at Belcherville, in the county of ll lontague and State of Texas, have invented certain new and useful Improvements in Advetising- Exhibitors and Phonographic Annunciators, of which the following is a specification.

My invention relates to new and useful improvements in advertising exhibitors and phonographic annunciators. Its object is to provide a changeableadvertising exhibitor,

which may be displayed in any public place, which exhibitor will make visible :1 new advertisement at regular intervals,-and which will be provided with a phonograph adapted to call out the advertisements at the same time that they are displayed. v

A further object. of the invention is to provide a suitable periodic mechanism which will produce a displacement of the device for receiving the advertisements at the proper intervals. y

A still further object to provide means by which the mechanism may be auton'iaticall set in motion at any desired time by means of clockwork.

Finally the object of the invention is to provide a device of the character described that will be strong, durable, simple and etli cient, and con'iparatively easy to produce, and also 'one, the various parts of which will not be likely to get out of working order.

lVith these and various other objects in view, my invention has relation to certain novel features of construction and operation an example of which is described in the following specification, and illustrated in the accompanying drawing, wherein:

Figure 1 is a front view of the exhibitor, the front wall of the casing of said exhibitor being removed. Fig. 2 is a sectional elevation of the exhibitor taken on the line ai -w of Fig. 1.

Referring now more particularly to the drawing wherein like numerals of reference designate similar parts in all the figures, the numeral 1 denotes the casing of the exhibitor. In the bottom of this casing is provided a phonograph of the usual construction. 2 designates the cylinder thereof, 3 the reproducer, and 4 the feed screw. A horn 6", having connection with the reproducer, extends to the upper ortion of the casin where it is provided with an outlet 7. An e eotrio motor 5 is adapted to operate the phonograph. pulley 9 the motor 7 is also adapted to communicate rotation to a shaft 10 mounted transversely of the :abinet. The pulley 9 is provided with two pins 11 near its rim, which pins are adapted to contact- With a star ,wheel of peculiar construction. This wheel consists of a disk 12 provided with a number of pairs of arms 13 and 14 said Through a belt 8 and a Patented July as, 1911.

wheel being mounted upon a shaft 14*.

The pins 11 are adapted to contachsuccessively with these arms, a partial rotation of the star wheel resulting. .The star Wheel-is provided with a radial arm 15 which once in each revolution contacts one of a. plurality of arms 16 carried by a disk 1'7 mounted on a shaft 18. Upop the shaft 18 is mounted a drum 19 which carries a number of advertising signs 20.

In order that each advertisement may remain stationary after reaching its proper position to be displayed, a collar 21 having a number of transverse grooves 22 upon its face is mounted on the shaft 14", and a pawl, 23, is pivoted adjacent to said collar, its extremities being adapted to engage the grooves thereof. This pawl'is connected by .a vertical lever 24- with the extremity 'of a pivoted lever 25 resting upon a cam 26 carried by the shaft 10. During each revolution of the shaft 10 the lever 25 is lifted by the cam 26 causingthe pawl 23 to release the collar 21 and thus permitting a new advertiscment to be displayed.

An electric switch-27 by which the motor 7 may bo-started is adapted in the following vmanner to be set into operation at any set time by an alarm clock 28 mounted in the upper portion of the casing. The key 29 by which the alarm is wound is extended to the'i car of the casing forming a shaft to receive a drum 30. A cord 31 having one of its extremities wound on the drum has its other extremity extendingto a drum 32 mounted upon a spindle 33. Said spindle also carries a cam 34 which bears against one extremity of the lever to the switch 27, being adapted to close the same. This switch will he opened manually when it is desired to stop the phonograph.

In the operation of the machine, if it be desired to start the mechanism at any given time the alarm of the clock is set for the pivoted at The other extremity of the lever is attached desired time. As. the alarm goes 01? there.

takes place a rotation of the key 29, which rotation communicated through the cord 31 to the cam shaft 33, and thus to the above right to make such changes and alterations in said device as fairly come within the of the following claim:

'hat I claim is: 1

In an advertising device, the combination with a rotatable receiver for a plurality of advertisements; of a motor, a shaft driven by said motor, a cam on said shaft, a second shaft carrying means adapted to rotate the receiver periodically from the first named haft, a collar on said second named shaft,

scope said collar having a series of grooves therein, a pawl pivoted adjacent to said collar and having one end in engagement therewith, a lever pivotally mounted with one end resting on said cam, a connection between said pawl and lever, whereby when said cam is rotated, said pawl will be disengaged from the grooves to display a new advertisement, a phonograph arranged to be operated by said motor adapted to announce each advertisement as it is displayed and a mechanism by which the aforesaid motor maybe set in operation at any desired time.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
