J. P. FREEMON ET AL CHANGEABLE EXHIBITOR Fi'led Sept. 27, l22 2 Sheets-Sheet 2 Patented June 12, 1923.

To all whom it may concern Be it known that we, JOHN 'P. FREEMON and EURA P. MOFADDEN, citizens of the United States, residing at Ann Arbor, in the county of Washtenaw, State of Michigan, have invented a new and useful Changeable Exhibitor, of which the following is a specification.

This invention relates to advertising apparatus and more particularly to automatic changing signs in which two series or subpacks or display cards or signs are disposed within a suitable containing housing, the card from the front of one sub-pack being removed in a serial manner to the front of a companion sub-pack, and in due order the card at the rear of the last mentioned subpack is moved to the rear of the first men tioned sub-pack. Incidentally to such shifting of the cards from one sub-pack to the other, the said sub-packs have lateral movement bodily in the case of one subpack in a forward direction and in the case of the other sub-pack in. a rearward direction.

The object of the invention is to provide a simple and eiiicient mechanism for shifting the signs at regular intervals so that all of the signs are brought into position for display in regular order.

With the foregoing and other objects in view which will appear'as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a front elevation of an exhibitor constructed in accordance with this invention with parts broken out for convenience in illustration.

CEANGEABLE EXHIBITQR.

Application fil ed September 27, 1922. Serial No. 590,888.

In the embodiment illustrated, a main frame or housing 1 is shown preferably of skeleton metal form although not necessarily so.

This frame or housing is here shown rectangular in form and is divided transversely about midway its ends by an upright hollow partition 2 which forms sign containing compartments 3 and 4;.

Arranged below the compartments 3 and 4 are transversely extending shafts 8,. 9, 10 and 11, the two shafts 9 and 10 being arranged in close proximity and each having a gear wheel 11 and 12 respectively which mesh with each other as is shown clearly in Fig. 2, operating to drive the end shafts 8 and 11 by means of sprocket chains '13 and 1.4 which pass over sprockets carried by said shafts, the chain 13 being locatedat one side of the frame in rear of the compartment 3 while the chain 14 is located in front of the compartment 4. These chains are designed for shifting the signs presently to-be described.

A motor 15 of any suitable character, preferably electric is connected to drive shaft 10' by means of a chain 16 passing over suitable sprockets on the motor shaft and on the shaft 10 whereby the chains 13 and 14 are driven continuously in opposite directions- Spring pressed pins 5 and 6 are mounted at the lower end of the hollow partition 2 with their front ends projecting into the paths of the signs to be shifted, as will be presently more fully described. Coiled springs 7 are mounted on these pins 5 and 6 and exert their tension to normally force and yieldingly hold the pins in projected position.

Each of with pull hooks 17 and 18 which are designed to engage the signs to be shifted.

The signs 2.0 comprise rectangular frames 21 preferably composed of wood, the ends 22 of which are beveled in opposite directions so that the signs will force themselves into position to displace the other signs as they are moved by the chains to facilitate the movement of the signs and to engage the spring projected, pins 5 and 6 which prevent more than one sign being passed from one compartment to the other at a time.

It is simply necessary to havev one sign more in one compartment than in the other, it being understood that both compartments the chains 13 and 14 are provided 3 311614 are of equal dimensions, and will accommodate an equal number of signs. For 1nstance,we W111 say compartment 4 contains ten *signsfwhich fill it "to its capacity, and compartment 3 contains nine signs, the

apparatus being in motion pull hook 17 engages the right hand end of the sign at the front compartment 4, thereby shifting the sign toward the left which results in the shifting of this sign fromthe frontl'of compartment tothe front of comp artment 3, thereby filling compartment 3to its capacity, ten signs, leaving compartment 4 with onlynine signs. After pull book 17 has transferred the sign from the front of compartment 4 to the front of compartment 3 and has been disengaged, pull hook 18 immediately engages the left hand end of the sign at the rear of compartment 3, thereby shifting said sign from the rear of compartment 3 toward the right which results in the shifting of the sign from the rear of compartment 3 tothe rear' of compartment 4, again filling compartment t to its capacity thereby forcing the .si gn pack for ward placing the sign at the front of com- }partment tiin position to be engaged by i the pull hook 17 immediately after-pull hook 18 hasdisengaged from the sign at the rear .ofcompartmenta. By shifting one sign at .atime 1n continuous succession, a gradual pullof the motor will be given and friction willbereduced to a minimum and will not :in any way interfere with the displaying of thesigns at the front or the rear These signs are exactly like except for the advertising ,niatter contained on their Iopposedfaces. ,These faces 23 and 24 are made of transparent material and spaced laterally to form between them light chambers as 25 in which are mounted electric light globes, vany desired number ofwhich may be employed, two being here shown and numbered 26. These: globes 26 are 3 mounted insuitable sockets with their contacts 27 projecting below the bottom bar of the. frame as shown inQFig. 7, and are designed to contact with cooperating contacts 28 carried, by the housing so that when pass i ng from one compartment to thefother, the

electric lights will be .cut off, andwhen in operative position the contacts on the sign will engage those-of the housing to light the lights 26. The operation of this apparatus is as folf The com rtm'ia tei filled with signs .20 disposed; in upright position one at the front and one at the rear of each c0mpartme'nt being exposed to, exhibit the advertising matter contained on their outer faces. .The motor. '15 being set in operation, the

lchainsgl3and 14 travel continuously in oppositedireotions so that atpredetermined intervals, the pull hook 17 will engage the the front of compartment a and the similar sign at the rear of compartment 3, I

As these signs move in themanner above described, the beveled ends 22 will engage the pins 5 and 6, moving said pins inwardly against the tension of their springs p'erwithout danger of twosigns passing at the ,sametime.

. a It will thus be seen that these doublefaced, double-walled signs will exhibit either by, day or; night the matter contained on their opposed faces. and that they will automatically shift at predetermined intervals without requiring any attention after the motor 15 has beenonce set in motion, the

the pull hooks on thechains.
