CHANGEABLE EXHIBITOR.

Application filed April 11, 1925, Serial No. 22,476. Renewed December 6, 1926.

My invention relates in general to changeable exhibitors, and has particular reference to a device of this character for progressively exhibiting display advertising.

rIhe salient features of my invention are concerned with the combination of a counter inkstand, preferably of the well-known Sengbusch self-closing type, and advertising exhibitor. The device is constructed to be placed upon a writing counter such as employed in banks, for example, and is adapted to automatically change the 'advertising display upon the use of the inkstand.

Devices of this character which I am familiar with, invariably do not register the advertisement with the sight opening provided therefor and hence are not efiicient. My improvementseeks to remedy this deficiency, and I accomplish the same by providing a definite'starting point andk a definite limiting and stopping point.

Other objects and advantages and the features of construction of the invention, willA appear in the subjoined description of the accompanying sheet of drawings, in which:

Figure 1 is a perspective view of the combination device; Fig. 2 is a plan, on an enlarged scale, with the cover removed; Fig. 3 is a central vertical section through the inkstand and casing, and full end View of the drum; Fig. 4 is a rear view, greatly enlarged,4on the line 4-.-4 of Fig. 3 to more clearly show certain parts and some of the parts are in section; and Fig. 5 is al view similar to that of Fig. 3 and showing the manner of operating the device.

Referring to the drawings in detail: I propose to construct the device in the form of a metallic cabinet 1 of a size and design suitable for the purpose, and thesame includes a base 2 and a removable cover 3. The cover may be made with an inclined top 4 having a recess 5 and inkstand opening therein, and a glass-covered window 64 above the same. rlhe recess has a flat portion 4'l' surroundingthe lflared top 8 of the inkstand, andthe window 6 includes a marginal frame 9 for the glass. r

The fundamental principle ofthe device is to change the advertisingY displayed through the window 6 every time a writing pen is inserted into theinkwell. To acco'mff plish this end in a positive and practical manner, I employ a drum 10 fiXedly mounted upon a shaft y11 and housed within the cover 3, and which drinn carries a series of advertising exhibits such as shown in Fig. 2 for example, properly spaced so that each exhibit in turn'w'ill show through the window 6 while the others of the` series are covered. The drum shaft is preferably pointed at its respective ends vand is supported vin correspondingbearings 12 and 13 mounted upon inner upright Walls 12 and 13. The said walls are bent up from the inner base 10. The cover 3 may be attached to the whole assembly as by knurled screws 3 screwed into tapped holes 4 in the said upright inner walls.

The inkstand best suited for my improvement is what is known'on the market as the Sengbusch ka self-closing type, shown in the drawings in light lines. The inkstand comprises a glass receptacle. 14, with a restricted throat or neck'15 surrounded by a partition super-well 16 which communicates with the main well 17 by a duct 18. A float i 19 in the main well is provided with a re-A duced part 2O 'extending into the neckl 15 and has' a termination contactingthe under-k side of the top S which latter caps the inl;- stand; The shouldered bottom 21 of the neck provides an abutment for the annular flange on the large end of the float. Vertical ducts 22 in the inner surface of the throat or neck provide channels through which the ink feeds to thetop of the float when the float is pressed downwardly by y the penpoint 23.

The glass receptacle 14 of the inkstand is bedded in a wooden holder 24 fitted in a compartment'formed by the walls 12', 13', base 10 and cross-wall 25. A cover is made for the inkstand which includes the flared' top 8. The` construction of the inkstand is conventional and needs no further detailed description. v

. Anchoredin the reduced end of the float is a wire 26the free .endA 27 of which is hooked over the projecting end .of a lever 28 vfixed to a'shafvtBO suitably supported in bearings31 and .u32 inthe upright walls 12. and 13. p This' shaft alsorcarries arc'vounterbalance'- 33 which is in the ferm of a rightf angled metal bar 'mounted in fjxedrelaton t'o the"V shaft"30 so as td assureVv a sensitive balance of the operating` parts. In other Words, the counterbalance serves to assist the introduction of the pen into the Well to press the float down and aid the float and said parts to return to normal position when the pen has been retracted. V

lixedly secured to the shaft of the drum 10 is ratchet Wheel Sli having` as many teeth as the desired number of advertising Zones to be on the drum. In this case I have chosen sin teeth, and each ot the latter are adapted to be engaged by a swinging hook 35 pivotally connected as at 36 to a lever 87 lixed to shaft 30. rIhe function of this hoolr is to reach under one of the teeth and engage it when the lever is in normal or at rest position (as best shown in Fig. 3) so that when the pen is inserted into the inlrvvell and the lever 28 pulled down, the opposite lever 37 in raising will impart an upward pull to the hook and turn the ratchet Wheel and through it the. drum, to change the advertising displayed through the Window 6.

To properly time the rotation of the drum so as to insure the exact spacing of the advertising with respect to the area of the window and thus prevent a part of tivo advertisements being shown through the Window at one time, I provide suitable stops ttor checking or arresting the rotation oit the drum. These stops preferably comprise a series of projecting pins 38 arranged in spaced relation on one side ot the drum so that when the lever 28 is pulled down and its opposed lever 37 elevated to turn the drum, alinger 39 lined on the end of the lever 37 will be raised to act as an abutment or one o't the pins 38, thus momentarily arresting the rotation of the drum. `W hen the float has been released the counterweight restores the balance ot the lever assembly to normal position again. In approaching the normal position the end oit the lever 37 carrying the tinger 89 Will be lorvered which will release the abutment ot the pin. To again arrest the drum and limit the movement of the same, I provide a loosely pivoted gravity Weight ll() adjacent the linger S9, which Weight will always hang plumb and engage the tooth oppositie the hoolr 35 (as best shown in Fig. 3) and loclr the Wheel in place, so to speak, from continued rotation ir" one should thrust the pen rsmartly and quickly into the inlrivell` From the foregoing description talren in connection with the accompanying dreivings,.the advantages ot the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and While'I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I desire to haveit understood that the device shown is merely illustrative and that such changes may be made, When desired, as fall Within the scope or' the appended claims.

I-Iaving thus described my invention, what I claim as new and desire to secure by LettersPatent o' the United States is the tolloiving:

l. In combination with an inlrstand ot the Sengbusch type having a reciprocating penactuated float, a rotating drum having advertising matter around the circumference or the same, a housing or'the drum, a Window in the housing for displaying progressive portions ofsaid advertising matter, lmeans connected to the float in the ink adapted to rotate the drum upon reciprocation of the float in one direction, and gravity-actuated means for arresting movement ci the drum to align the advertising matter in display relation Wit-h said Window.
