Application led May 18, 1808. Serial No. 438,358.
To all'wlwm it may conc-em:
Be it known that I, EDWARD F. CANNON,
a citizen of the United States, anda resident of Portland, in the county of Multnomah and State of Oregon, have invented a" flexible member and being adapted to sup-.
port carriages for holdin the goods to be displayed, the carriages ,eing operatively connected through the slots, with thevflexible traveling member.
The object of the invention is to provide a simple,l inexpensive and eiiicient display apparatus for exhibiting goods or wares, .in which the goods are arranged upon carriages which travel successively and continuously in a plurality of directions and thus show the goods to the best advantage and from `different sides, and in which the carriages are movably supported upon the Hoor, which, at the same time, serves 'to conceal the mechanism for actuating the carriages.
The invention consists in* the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claim. i
Reference is to be had to the accompanying drawings formin a part of this specification, in which simi ar characters of reference indicate corresponding parts in all the views,'and in which- .Figure 1 is a plan view of one form of my display apparatus; Fig. 2 is a longitudinal section on the line 2-2`of Fig. 1; Fig. is an enlarged, partial, longitudinal section of the traveling member, showing a carriage in side elevation; Fig. 4 is an enlarged, transverse section showing a traveling member, and a carriage, the latter supported upon the Hoor; and Fig. 5 is an enlarged side-elevation showing a sprocket for particularly useful in connection withstores, y
shop windows and the like, it can also be advantageously employed for other purposes where itis desired to display or exhibitarticles, or in which it is necessary to cause articles to move continuously and successively in predetermined directions. I have shown, for example, carriages. of certain form, but wish to emphasize that the construction of these carriages can be varied to suit individual preference -or to allow for dii'erent kinds and sizes of articles to be supported upon the carriages. The traveling member which controls the carriages may be actuated in any suitable manner to cause it to travel continuously, or interruptedly, in the same or in opposite directions.
`Referring more particularly to the drawings, I provide a floor 10 which may be fashmetal or the like. A base 11 'having upwardly disposed sides 12 carries the Hoor between the latter and spaced from the base.
The base may consist ci the Hoor of a Shop window, or 'of a store, or may be formed so that it is removable together vwith the floor 10 and rigid therewith. A continuous slot ,13 is formed in the door 10 and may be arranged in any desired manner, as shown for example, with a plurality of oppositely disposed runs 14. The slot constitutes the track which direc-ts the' travel of the carriages which are used for displaying the goods, and the form and arrangement of the slot can be yvaried in any` desired Inanner. In the form of my invention shown,
herewith, l employ a transverse strengthen-y ing bar 15 having oset channel-shaped portions 16 where 1t crosses the various runs of the slot, for a purpose which will appear more clearly hereinafter. A iiexible member 17 consisting preferably of'a chain as shown herewith, 1s positioned under the Hoor 10 and conforms to the arrangement of the slot 13. Posts 18 are pivotally mounted underneath the floor', and have sprockets 19. The posts are arranged at the curves or return bends of the slot and are held in posiaon by means of Suitable braces 20. The
sprockets 19 engage the chain 17 and carry' rIlhe os'et channel-A and direct' the same. shaped portions 16 of the member 15 are for the purpose of. permitting the chain to travel therethrough.
I prefer to fashion the iiexible member or chain from links 2Oa and 21 arranged in pairs, as is shown most clearly in ilig. 3. The links 21 at the ends, have openings which receive pivot sleeves 22. Pivot pins 23 are arranged within the sleeves 22 and are received at the extremities by suitable openings of the links 20a, whereby the links 20, and 21 are pivotally connected. At the ends, the pins have enlarged heads to Vhold them in position.
Carriages 25 which may be oi any suitable form, are arranged upon the floor 10,-a and 20 have pivoted brackets or casters 26 provided with supporting Wheels 27 for carrying them upon the Hoor. Stems 28 extend` through the slot 13 and are rigidly secured to the carriages. At the end, underneath the Hoor, each stem has a plate 29 provided with downwardly extending pins 30; these take the place of the pins 23 at one of the links of the chain and are inserted in the corresponding sleeves 22. In thisway the carriages are operatively connected with the chain and are caused to travel as the latter is actuated.
Having thus described my invention,
lthe pivot pins connectingthe links, and a carrlage provided with a stem projecting through the said slot and carrying a plate to whicha pair of the pivot pins of the chain are secured. 1
ntestimony whereof l have signed my name to this specilicationfin the presence of two subscribing witnesses. v
