CHANGABLE Exiiifsi'roe. j

T0 all whom it may concern.'

Be it known that I, BERNARD PERITZ, a citizen of the United States. and a resident of Brooklyn, in the county of Kingsv and State of New York, have invented certain new. and useful Improvements in Changef able Exhibitors, of which the following is a specification.

This invention relates to improvements changeable exhibitors for the display of news items, advertising matter, pictures, etc;

The objects of this invention are to eliminate the objectionable features of this class of advertising mechanism, and to create the largest possible advertising space in comparison with the container of the mechanism and sign plates, and to present to the public an advertisement or sign which has a. flat or even surface that stands vertica and is easily read. n

Thefurther objects are to provide an exhibitor of this class on which the advertisement can be used on both sides of the exhibitionv plates and the matter of an advertisement or picture may be displayed onl two platesand `exhibited at the same time, and the gap which appears betweenl the plates of this style of exhibitor is eliminated, or in other words the two plates appear' to the eyes as one.

The still further object is to provide a device of this character from which the sign can be easily and quickly removed as a whole or in part and new matter inserted 'when desired, so that a single advertisement or more may be changed without disturbing the others or interfering with the mechanisin.

T he still further objects are to provide a.

mechanism which can be easily and cheaply manufactured and operated without getting out of order.

lt will be seen that I have accomplished the foregoing objects, by referringto the accompanyingdrawing forming a pai't of this specificatiomcf which- Figure 1 is a front elevation of my improved exhibitor; F ig. 2.is aii end elevation partly broken away to show the retarding springs of the sign holder; F ig. 3 is a vertical section taken o-n the line 3.*3 of Fig. 2; and Fig. 4l is a perspectiveview of one of the trunnions upon which the signplate is operated and showing the retarding memspecificati@ of Letters raient. [Paf-heed May-16, i916. Application sied Augut i212, 1914. r serial No; 858,111.

By referring. to the several views it will be` seen that I have provided a suitable housing 4f the contourjof which follows the outline of the travel of the edge of the sign plateswith the exception that at tlie'front,

where the sign plates turn over, or in other words swingen their trunnionsy 6 .and pass through a motion of one hundred and eighty degrees and present their reverse side to view; at this point the housing 4l. is provided with a rectangular opening 7 which allows the sign plates to swing out into space.

Located in the bearings 8 of the endv walls 8 and 9 is the operating shaft 10, which is provided at one end with flattened surfaces 11 so that it maybe revolved ywith a key or crank yin order to wind up the sev-- eral springs 12, 13, 14, 15and 16, which are contained in the dr'umsl?, 18,19, 20 and 21 respectively, which revolve loosely on the shaft 10, which isv prevented from rotating by the ratchet 24 and pawl 25. *Pinned to the shaft 10 is a sleeve 22, to which is secured one end of the spring 12, the other end of which is secured to the periphery of the drinn 17, whose 'hub'17" extends into the drum 18, and, one end of the spring 13 is secured to the hub 17 and the other end to the inner periphery ofthe Ldrum 18. The other drums are connectedup in like manner, the spring 14 connecting the hub 18"' and drum 19, and the spring 15 the hub19 and drum 20, and the spring 16 the hub 20 and drum 21, which inrturn is secured tok the revolving disk 26, which is connected to the revolving disk r27 by a plurality of tie rods 28. Near the periphery of the disks 26 and 27 are a plurality ofv holes evenly spaced, which form bearings for the trunnions 6 of the signplat'es 5. The trunnions "f 6 are provided with shoulders or bearing surfaces 6 to keep the sign plates 1n alinementf and which are secured in themain in these slots are secured the retarding members or plates 29, whichcome into cony tact with the springs30, which are secured to the extensions 31 on the lend walls 8 and much'for'ce against the preceding one. The

springs are provided with tension bolts V32 to increase or decrease the strain on the plates, 29, and the bolts are adjusted through the openings 33 in the end walls.

Secured to the end wall 9 is a segmental plate to the trunnions 6 so that when two signs are being. exhibited the edges of the two signs come' in contact with each other, as clearly shown in Figs. 1 and 2;v that is to say, when the face 5 of the upper sign is exhibited the lower edge 5 of the sign plate 5 touches the upper edge 5 ofthe lower sign plate 5 when the face 5 is exhibited. The sign plates 5 are provided with small clips 39 around their edges which extend on both sides of the plates, and under these clips are inserted the `advertising cards, which have been first out in two so that two plates carry one sign or advertisement, or each yof a pair of plates carry a half of one sign on their adjacent faces. y

The operation is very simple. By revolving the shaft 10 the spring 12 will be wound up, and when tight it will cause the spring 13 in its turn to be wound up, and so on until all of the springs are wound tight on the shaft 10, which is held from turning or unwinding by the ratchet 24. `Thestud 36 is then withdrawn, which allows the disks 26 and 27 to `revolve at a speed which .is regulated by the kkfriction brake 34. The revolving of the disks 26 and 27 carries the sign plates around with them and causes the sign plates to assume the position shown in Fig. 2,. and it will be seen that the two plates which are being exhibited stand perfectly vertical and have afslow downward travel, which is regulated by the length of the members 40. As will be seen,r when the upper edge of the sign plate passes below the end of the members 40 its weight above the trunnions 6 will cause the signplate to swing forward and down through themotion of a semicircle and present its oppositey side to view, and in so doing the retarding members 29. of the sign swing in a semi-circle under the springs 30, and upon thelast part of their movement raise the springs 3 0 from the dotted position tothe full line position shown in Fig. 2,

andthus the retarding strain gradually increases and reaches its maximum `resistance on the last part ofthe movement of the sign. The continuous movement of the disks 26 and 27 causes the next plate to be in position as the previous plate turns, and this movement of the disks also causes the re- 'tarding members to gradually leave the springs 30 and allow them to resume the dotted position before the next plate is readyto turn on its trunnions. When it is desired to stop thek sign, all that is necessary is to insert the stud 36 in any of the holes 37, and if it is necessary to change a sign the old sign can be taken out and a new one slipped in under the clips 39.

Having fully described my invention, what I desire to claim is:

1.` An exhibiting device consisting of a shaft, a pair of disks on the shaft, a set of sign plates, a pair of trunnions for each plate consisting of a slotted bar engaging the plate and a journal projecting from each bar, clips on the plates for removably secui'ing cards on the plates, the trunnions being swung between the disks in a circular series, an arm extending radially from one trunnion of each plate, and a spring strip arranged to engage each said arm to retard the momentum of the plate as swung to reversed exhibiting position.

2. An exhibiting device consisting of shaft, a pair of disks on the shaft, a set of sign plates each having a pair of trunnions,

the trunnions being swung in the disks respectively in a circular series, and the plates being so disposed as to be consecutively positioned in vertical alinement with adjacent llO the disks, a half sign on each adjacent plate with the sign disposed on adjacent plates, each plate having a pair of trunnions working in evenly spaced bearings in the disks, an adjustable spring, and a member on each trunnion that contacts with and lifts said spring on the latter part of the turning movement of the trunnions. f

Signed at New York, in the county of New York and State of New York, this 19th day of August, A. D. 1914.
