lUNllTlBllD TATS RICHARD R. WHITING, OF NORWOOD, OHIO.

GARD-EXHIBITING DEVICE.

Application filed November 22, 1909.

To all whom it may concern:

Be it known that I. RICHARD R. XVI-Urine, a citizen of the United States, and a resident of Norwood, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Card-Exhibiting Devices; and I do declare the following to be a clear, full, and exact description thereof, attention being called to the accompanying drawing, with the reference characters marked thereon, which forms also a part of this specification.

This invention relates to certain new and useful improvements in devices in which exhibits in card-form, pictures, photos for instance, may be exposed for inspection and viewing.

The leading feature of this invention concerns the arrangement. means and their construction. whereby a collection or set of such exhibits is supported in a manner that the single exhibits forming part of such a set may each be conveniently viewed, one after the other, by one or more persons.

In the following specification and particularly pointed out in the claims at the end thereof, will be found a full description of my invention, together with its operation, parts and construction, all of which is also illustrated in the accompanying drawing, in which Figure 1, shows a vertical cross-section of the apparatus. Fig. 2, shows a section of the central part of the apparatus resulting from removal of the member shown in the center of the apparatus now nearest to the observer. Fig. 8, is a similar view and shows the farther side of the casing of the apparatus appearing in Fig. 1, and the operating parts located immediately in front of this side. Fig. i, is part of a side-view of the apparatus showing it as it appears when viewed in the same direction as it is in Fig. 1, parts of the side of the casing nearest the observer being broken out, showing a section similar to Fig. 1, with a modified arrangement of the view-supporting means. Fig. 5. shows part of a frontview and part of a central vertical section, the section being taxen in a plane at right angles to the section shown in Fig. 1. Fig. 6, is a part of a section similar to that shown i the preceding view and with the modified viewsupporting means shown in Fig. l. Fig. 7, is an enlarged sectional detail-view Specification of Letters Patent.

I and shows manner of connecting the viewsupporting arms. Fig. 8, is a similar view taken at right angles to the preceding View. Fig. 9, shows the inner connected end of one of the view-supporting arms. Fig. 10, illustrates modified means for connecting these ends of the viewsupporting arms. Fig. 11, shows a modified manner of supporting the views.

The letter A indicates exhibits which are in card-form and supported on slender arms B of thin elastic material like steel for instance. Blades formed of clock-spring steel are very desirable. The exhibits are arranged in a manner that these arms may engage them and may be used for the purpose of moving them, one after the other into position for viewing. VJ hen the exhibits are connected, the connection may be a direct one to these arms as shown in Figs. 1, and 7 or intermediate carrying means may be used like a frame or a flat card 15, as shown in Fig. 11, which is provided with slits 16 which receive the corners of the views. This connection in either case may be a permanentone, or one permitting removal, of the exhibits from the intermediate carrying means, or of the exhibits from the arm in case of their direct connection thereto. The cards may bear matter to be exhibited, on one side only, or on both of their sides. This latter etlect may be obtained by securing two cards a a, see Fig. 7, to each other back to back, each of these cards having 011 one side matter to be exhibited. The connection of two of such views to each other, back to back, may be by any suitable means, an adhesive substance being preferred. In such case a space between the two cards and between their marginal edges may be left disconnected to form a pocket 17, see Fig. 7, which may receive the supporting arm, the exhibit being held as shown in Figs. 1, 5 and 7. By having the arm fitted closely to such a pocket an exhibit may be readily held in this manner without any additional means and may be conveniently removed, to be replaced by another exhibit similarly prepared. hen one side only of a card bears a view, such a pocket may be formed by securing a strip of material, paper for instance, against the back of the card, or against the back of the intermediate carrier 15.

The connection between the views and their arms or their intermediate carriers. or between these latter and the supporting arms may oe a. permanent one by means of glue, rivets 18 as shown in Fig. 11, or other equivalent means. A. number of such arms B is secured to a rotatable shaft 19 from which they project substantially, radially and whereby when said shaft is rotated, these arms, with the views engaged by them, are moved correspondingly in a circular direction. The connection of these arms to shaft 19 is not rigid, but permits each arm to have a limited movement, independent of the movement received from the shaft, and in a peripheral direction, that is in the plane in which they are carried around by the shaft. For such purpose a hub C is provided and rigidly mounted upon shaft 19 to which these arms are pivotally connected. This hub consists of two spaced disks c, mounted upon shaft 19 and between which and at or near their edges, the inner ends of these arms are connected. For such connection, the arms at their opposite, parallel edges are shaped to form laterally extended trunnion-journals Z) Z), which are fitted to occupy recesses 21 provided opposite each other in these disks and forming bearings for these journals. These recesses may be obtained by arranging a circular row of holes 21 in the disks as shown in Fig. 10. A preferable method however is by using disks which have notches in their edges in which the arms are endwise seated as shown in Figs. '7 and 8, the advantage of this an rangement being that the recesses may be close to each other permitting use of a larger number of arms whereby the exhibit-carrying capacity is correspondingly increased. One disk so notched may be used if of sufiicicnt thickness, or two adjacent to each other. Fig. 8 shows such a disk in about full. size with two arms in position, illustrating how close these arms may be placed in reality.

Means are required to confine the ends of the arms in position within the notches. This done by caps having circular shoulders 23 which extend over ournals Z) 7) of the arms. These caps are held in position by collars 24-. Beyond journals 1), the arms are shaped to form shoulders adapted to come in contact with the peripheral edge of caps which edges by preference are flanged as shown at 26 to render them more rigid. The distance between journals Z) and shoulders on the arms is longer than the distance between shoulders 23 and flanges 26 on the caps and the journals are left free to turn in their hearings so that the arms may perform. the limited movement and independent of the movement they receive from. rotation of shaft. 19 as previonsly mentioned. T he arms move positivel y with this shaft, only when said shoulders are in contact with the edge of the caps as shown in Fig. 8. The object of this arrangement will be presently made clear.

Shaft 19 is supported in opposite sides I? of a suitable case and may be rotated in any suitable manner. A. ratchet wheel 528 may be used, which is actuated by a pawl 29. carried on a lever 31, which may oe operated. by a push-rod extended to the outside for access. A stop confines the actuation to proper limits and a spring 34 restores the parts to normal position after each actuation, which position is defined by a stop 30.

is a locking-pawl to hold wheel 28 in the position to which it has been advanced.

36 is a stop arranged within the casing and in a position so as to be located in the path of the outer edges of the exhibits. Engagement with the extreme ends of arms B is preferable, since direct engagement with the edges of the exhibits would wear them, in case they are made of paper. This presumes of course that all arms are of equal length.

The arrangement, function and operation of the concerned parts are as follows, reference being had to Fig. 1, and to the position of the parts as shown there and in which they are left after a preceding actuation of push-rod 32 has effected a limited rotation of shaft 19. The extent of each of these rotations is such that it would carry the outer end of an arm B to a position slightly beyond stop 36 if this latter were not present. Its presence however limits the movement of this outer end of the arm and holds it back without preventing the n'iovcment of its inner end which follows the rotating hub to which it is connected. his interference with the movement of the outer end of eaclr arm B, which prevents this end from following the inner end, sets up a springtension in the particular arm so retarded. If pushrod 32 is new again actuated, the immediate effect will he a forcible release of the retarded arm 13 from stop 36, whereby this arm under the impulse of its spring-action will at once flop over to the other side, which movement is one independent from that due to rotation of shaft 1?) and soiely spring impelled. This independent movement is made possible by the particular manner of connecting the inner ends of arms 1% to huh C as before described. This ll'lOVGll'iQllt is limited and comes to a stop as soon as shoulders on the particular arm come again in contact with the outer edges it; of caps 22 leaving the released arm in a posi tion as shown in 1, upper one to the right. lit will now be noticed that by this retardation of an arm a gap is produced in a set of views in the upper part of their circular path and as shown in Figs. 1 and -l-., that is to say, the exhibits drop apart thereat, one being on one side of this gap and another on the other side. A view on one side of a card, they being of course all on thesame side on each card, may now be readily observed either direct or through a viewglass of which 37 are the lenses and supported in proper position on the casing, opposite the exhibits in the gap. If each side of a card bears a view. another viewglass becomes necessary, and if these viewglasses are arranged as shown in Fig. 1, two persons may use the apparatus at the same time, there being always a view opposite each glass. To see all the views on both sides of the cards, requires use of both viewglasses, one after the other.

38 are customary hoods to shade the eyes. Observation may however be also direct and without view-glasses.

In case the apparatus is used as a stereo scope, it becomes necessary to provide for a division or septum between the lenses on the inside. Stop 36 may serve for this purpose, it being a strip of metal, shaped as shown in Fig. 1, and adjustably connected to a bracket 39 which extends into the casing between the lenses. The arrangement as shown in Figs. 1 and 5, presumes a support of the views on arms B in the manner indicated in Figs. 7 or 11. As shown in Figs. t and G, the exhibits are not sup 301t8Cl on these arms, but rest at opposite ends in cir cular run-ways 41 provided opposite each other on the shaft or on opposite sides of the casing. In this case arms 3 extend into the spaces between adjoining cards and merely push them around through the run ways. Access, to change the exhibits, may be had through a door 42. Such changes may be effected after the door is open, by rotating shaft 19 to bring the various arms successively opposite the door-opening in convenient position for the purpose.

In case the views are supported as shown in Figs. 1, 5, 7 or 11, it may also be done by taking the entire set out of the casing, shaft 19 for such purpose being removed from its earings. In case the views are permanently connected to arms B, so as to require their removal from the hub, then the shaft with the entire set of exhibits must be taken i the shaft a plate 44: is aflixed which is fitted to a slot in a laterally extended hub to of ratchet-wheel 28 in which it is held by a set screw 46. vVhen the shaft is removed the ratchet-wheel remains in position, being supported in a bearing d7, secured to the adjacent side of the casing. One edge of plate 44 is bent to form a shoulder 48 which de fines the position of this plate in the slot of hub and which position is one which 10- cates the end of the shaft in the center of this hub. wee Figs. 3 and 5. A convenient way of shaping arms B is by notching at one of their ends, their opposite longitudinal edges in the manner indicated in Fig. 9, thus producing journals 6 Z) and shoulders Stamping by use of dies is a preferable way .of obtaining the shape of the arms, since by such means the necessary equality in shape of all arms is assured.

Having described my invention, I claim as new:

1. In a view -exhibiting apparatus, the combination of a set of equal sized view moving arms of stamped metal and provided with internal trunnion-journals, a hub to which these arms closely spaced are pivotally connected by means of these journals and a rotatable shaft on which this hub is mounted.

2. In a view-exhibiting apparatus, the combination of a set of elastic view-moving arms, a hub on which they are endwise seated, means engaging this end at opposite edges to hold the arms to the hub, and a rotatable shaft upon which this hub is mounted.

3. In a view-exhibiting apparatus, the combination of a set of view-moving arms, notched in opposite edges at one of the ends to produce trunnionjournals at one end of those notches and stops at their other end, a hub to which these arms are held by means of these journals and which is provided with means adapted to interact with the stops mentioned to limit the movement of the arms on the hub and a rotatable shaft upon which this hub is mounted.

4t. In a view-exhibiting apparatus, the

combination of a set of view-moving arms of elastic materlal having trunnionournals on their opposite edges and shoulders beyond these journals, a rotatable shaft on which these arms are pivotally mounted, a stop located in the path of the outer ends of these arms, means to rotate the shaft sufficient to carry the ends of the arms, one after the other against the stop mentioned in a manner to setup a spring-resisted retardation in each arm, while at the same time releasing a previously engaged arm to permit the same to swing, spring-impelled, on its pivotal connection independent of the motion received from the shaft, and means adapted to be engaged by the shoulders on the arms to limit this independent motion.

5. In a view -exhibiting apparatus, the combination of a case provided with a viewglass having two lenses, views supported inside of the case opposite this view-glass, arms of elastic material for moving these views in position opposite the view-glass, means to actuate these arms for the purpose and a stop adapted to temporarily engage these arms one at a time to hold them in position for viewing, said stop being so formed and located as to serve also as a septum for the lenses of the view-glass.

6. In a view-exhibiting apparatus, the combination of a shaft, means to rotate it, a peripherally notched member mounted on this shaft, arms of elastic material adapted to actuate exhibits and provided with lateral projections seated in these notches, means to confine them 1n position therein and a stop located in the path of the free ends of these 15 RICHARD H. lVI-IITING.
