STES PTE j FFIQEo ORLANDO E. KELLUM, OF LOS ANGELES, CALIFORNIA, ASSIGNOR TO NATIONAL STREET AND STATION INDICATOR COMPANY, OF LOS ANGELES, CALIFORNIA, A CORPORA- TION 0F CALIFORNIA.
EXHIBIT DEVICE.
T0 all wiz-0m t may concern Be it known that I, ORLANDO E. KELLUM, a citizen. of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and. useful Improvements in Exhibit Devices, of which the following is a specification.
This invention relates to an exhibit device of the class adaptable for street and station indicators; and the invention consists particularly in a novel combination of a chain of exhibit plates and a rotatable member,
preferably polygonal, and a set of guides n by which the exhibit plates are moved from one suitable storage chamber into another.
One of the novel features of my device consists in the guide mechanism by which the exhibit plates are forced to pile flatly one on the other in the storage chambers, being thus stored in a minimum space.
In the embodiment of my invention shown in the drawings, there are many features which may be changed without changing the invention. I have shown a polygonal rotatable member of six sides, but this is used for no other reason than that the actuating mechanism which I now use to operate this exhibit device is capable of rotating the device most eiiiciently through a sixth of a revolution. ,The specific arrangement of guides and the relative arrangement of the storage chambers and the rotatable member are not necessarily in the form shown in the drawings; it being possible to make other arrangements, which arrangements will become clear from the following specification.
In the accompanying drawings: Figure 1 is a vertical section of my improved device. Fig. 2 is a vertical section taken on line 2 2 of Fig. 1. Fig. 3 is a horizontal section taken on line 3 3 of Fig. 1. Fig. 4 is an enlarged perspective detail showing the construction of the display plates and their method of connection.
In the drawings 5 designates a case of any desired configuration, being shown as rectangular and of suflicient extent to accommodate two storage chambers 6 and rotating mechanism 7 arranged above the storage chambers. Rotating mechanism 7 consists principally of a drive shaft 8 through the medium of which the mechanism is operated, and members 9 rigidly mounted on the shaft and forming what might be termed a Specification of Letters Patent.
Application led March 16, 1911.
Patented Apr. 9, 1912. seriai No. 614,788.
skeleton drum of six sides over which the chain of display plates passes, as will be hereinafter explained. Members 9 are provided instead of a solid drum, as the inertia of the rotating parts is thereby greatly decreased, correspondingly decreasing the amount of energy required for rotating the device. Shaft 8 is situated in the upper part of case 5, and the skeleton drum formed thereon by members 9 is preferably situated above the storage chamber 6, the outermost peripheral points of members 9 being approximately over the outer edges of chambers 6 as is best shown in Fig. 1. Each of chambers 6 is provided with a guideway 10 at its ends, the guideway 10 leading from points adjacent the periphery of the skeleton drum formed by members 9 (approximately frompoints numbered 1l in Fig. l) downwardly and inwardly toward each other and toward a separating wall 12 between the two storage chambers. The guide leads preferably in a gentle curve to a point close to wall 12 and then leads to the bottom of the storage chamber parallel to the wall, as is shown in the lower part of Fig. 1.
Each plate is provided with a tab 28 on each end near one edge, the tabs on the plates being arranged adjacent when the plates are assembled into the chain. By this method of assembly the tabs are all arranged at alterna-te points of the juncture of the plates, so that half of the lines of pivotal juncture of the plates have tabs adjacent them and the other half have not. Tabs 23 are adapted to project into guideways 10 and to keep the edges of the plates to which the tabs are directly connected moving along those guideways. Thus, supposing the movement of the rotating mechanism to be that indicated by the arrow in Fig. 1, it will be seen that the edges of the platesprovided with tabs 23 will be forced to move down into the storage chambers along guideway 10, the other edges of the plates hanging outwardly from the guideway in a position which they will naturally assume under gravitational action. As the mechanism is rotated and the chain of plates is movedy into the left hand storage chamber, the angle between adjacent plates will be decreased until, at last, as the plates reach the pile in the bot-tom of the storage chamber, the plates are parallel to and lying upon each other.
The plates and their information are' viewed through an aperture 35 in the side of the case. This aperture may be on either or both sides, so as to show the information carried by the plate on either or both sides of the machine. In case there are apertures on both sides ofthe machine, it will be seen that the apertures must be cut so as to each disclose one half of a plate, the two apertures being then arrangedi one at one end of the case on one side and the other at the other end of the case on the opposite side.
I have shown a means of keeping the plates 2O in position on the members 9, consisting of semi-annular members 30 engaging in notches 31 cut in the edges of the plates near their ends. The plates are thus held against the skeleton drum and also prevented from being longitudinally displaced.
It will be seen that the preferred arrangement of guideway 10 is this--that the guideway lead downwardly and laterally to a point not directly under the po-int of delivery of the chain of plates from the rotating mechanism. The action is most eiiicient when the unguided edges of the plates pile up in a line practically beneath the po-int of delivery of the chain of plates from the rotating mechanism and when the guided edges of the plates are moved laterally from the point of delivery by an amount practically equal to the width of the plate. However, the arrangement may depend on other considerations and mayl depend greatly on the number of sides provided for members 9, and the consequent size of plates 20 as compared to the space suitable for storage chambers directly beneath the rotating mechanism. It has been found in practice that the plates will pile up even if the guideway leads directly downwardly from the delivery from the rotating mechanism.
Having described my invention, I claimzg 1. An exhibitI device, comprising a pair of vertically arranged storage chambers situated adjacent each other back to back, guideways leading from the upper front to the lower rear portions of the chambers, a rotatable member located above the chambers and having its outermost peripheral lines situated approximately above the front edges of the chambers, a chain composed of transversely extending plates hingeably secured together along their longitudinal edges, each plate having guideway engaging means and having notches out in its longitudinal edges, and a segmental plate arranged above the rotating member and adapted to have its curved edge enter the notches in the plates.
2. An exhibit device, comprising a pair of vertically arranged storage chambers situated adjacent each other back to back, guideways leading from the upper front to the lower rear4 portions of the chambers, a rol tatable member located above the chambers w and having its outermost peripheralvlinessituated approximately above the front -edges of the chambers, a chain composed of transversely extending plates, each plate having slots therein, and flexible members extending the length of the chain of plates and passing through the slots in the plates to hingeably connect the plates together along their longitudinal edges, each plate having guideway engaging means and having notches cut in its longitudinal edges, and a segmental plate arranged above the rotating member and adapted to have its curved edge enter the notches in the plates.
3. In a device of the character described, a rotatable member, a chain of plates adapted to pass over the member, said chain being formed of a plurality of plates hingeably secured together along their edges, each plate being provided with a notch in its hinged edge near its end, and a segmental plate situated over the rotatable member l1( and adapted to have its curved edge enter the notches in the plates.
