DISPLAY APPARATUS.

Application filed February 28, 1924. Serial No. 695,649.

The primary object of the present invention is the provision of a display apparatus for the exhibition of articles of merchandise while such articles are travelling through a predetern'iined path. The articles, there fore, may be displayed in regular succession to the observer, and in convenient access for removal from the apparatus when such is desired.

More specifically, the invention conte1nplates an ap 'iaratus oi? the character men tioned designed for the combined storage and display of clothing, its construction being such as to economize in the space required for storage, thereby enabling a maximum number of garments to be stored in a lnininuu'u area, and permitting the garments successively to be dispiayedwhile so stored. The economy of storage space thus obtained is reflective to eliminate to a large extent the shelvingand display cases heretofore used for such purposes, and enables the proprietor oi a store to reduce the floor space necessary tor such shelvingand cases.

Furthermore, the invention has in view the production of a display apparatus wherein provision is made to insure proper travel of the garments through the machine without liability to injury of the garments or entaiu leinent thereof with the moving parts of the machine.

The invention also aims to provide aidisplay apparatus such as re'tcrred to wherein the operative parts are so related as to ali ord a most compact m'ganization, thereby saving in the material. for the construction of the apparatus, and rendering the parts of the latter readily acccssible for repair or replacement when damaged or worn.

To the accomplishment of the foregoing, and other objects which will appear as the nature ot the improvements is better understood, the invention consists substantially in the novel construction, combination and ar rangeinent of parts hereinaiter fully described, illustrated in the accoi'npanying drawings, and Finally pointed out in the appended claims.

The en'ibodilnont ot the invention herein disclosed. is believed to be :tully illustrative of the same, and incorporates a. practical adaptation of the invention for the uses and purposes "For which. the same is intended. However, it is to be taken in an illustratiye sense, and therefore not to be considered as restricting: the invention to that form which is herein delineated.

. ROfOlTlTlQ now in detail to the accompanying drawings, the herein described display apparatus includes a base 10 with which is associated a pair of suitably spaced vertical supports 11. Each of these supports is of sectional construction, so that they may be extended or retracted, for a purpose to be presently stated, to which end each support includes a lower member 12 and an upper nien'ibcr l3. At the outer face (it each support 11. and located at the margins thereof. 90 is a pair of vertical guide flanges .l-ll:, said flanges being connected to the lower nie1nhere 12, and projecting z-iuilicientl above the same to provide ways on \Yllll the upper members 13 are slidably nuiunted. The members 13 are connected to the guide flanges ll by nie es oi? :1 pl uraliiy (it bolts 15, said bolts pas Lllltlllfll slots ll) which are tor-med in the guide {lai'i es l l, said bolts exerting a bii'idiup' action b veen the upper members l3 and the guide flange: and thereby to hold the upper members in positions o'li' adjustment with respect lo the lower inmnbers 19. The upper members iii are faced with wear-plates 17 at those portions which are contiguous to the slots 16, and at which points the bolts 15 also are located, in order to prou'iote the binding action of the bolts 15 when the some are tightened, and also to prevent undue wear on the members 13 which may arise in the adjustment of said members with respect to the members 12.

, At a suitable point in the members 12, preferably at a relatively low point with respect to the entire height of the structure, a driving shaft 18 is positioned. This shaft spans the space between the supports 11, and its ends are journalled in suitable bearings 19 connected to and extending through the lower members 12 of said supports. At the extremity of one of the projecting ends of the shaft 18 a spur gear 20 is fixedly connected so as to impart rotation to the shaft 18 when said gear 20 is actuated. The gear 20 meshes with a spur pinion 21 which is fixedly connected to a power shaft 22 through the medium of a worm wheel 23. This worm wheel 23 is'in mesh with a worm 24 connected tothe armature shaft of an electric motor 25. The motor 25 is controlled by suitable switch mechanism, which it is unnecessary here to describe, the same forming no part of the present invention. Suflice it to say that said switch mechanism is of such character that when the brake mechanism, about to be described, is acting to maintain the display apparatus inactive, the electric motor 25 is at rest, said motor becoming energized when the restraining action of the brake mechanism is released.

Also associated with the shaft 22 is a brake drum 26 and co-acting with said brake drum is a brake lever 27 which is adapted normally to frictionally engage the brake drum 26 and preventrotation thereof. This is due to the action of a coil spring 28 which surrounds a link 29, one end of the latter being connected to the brake lever 27, while the other end is connected to a foot lever mounted at the lower portion of the machine. The link 29 passes through a perforated arm 30 against which the upper end ofthe coil spring 28 abuts, the lowerend of said spring contacting with a collar 31 adjustably mounted upon the link 29, and thereby per mittingvarious degrees of compression to be imparted to the spring 28. The pressure of the spring 28 is exerted normally to force the link 29 in a downward direction, thereby exerting a pull on the brake lever 27, and establishing its frictional engagement with the brake drum 26. hen, however, the foot lever 30 is manipulated by application'of pressure thereon, the link 29 is pushed upwardly against the pressure of the spring 28, with a resultant release of the lever 27 from the'drum 26. This release will permit the electric motor 25 to operate freely and driving action to the For convenient application of the motor 25 the same is seated upon asupporting table 32 held in proper position by an inclined strut 33.

WVhile the motor 25 is the primary source of driving power for the herein described apparatus, provision is made for operating the same manually, for those conditions where only limited operation of the apparatus is required, and to this end there is connected to the outer extremity of the power shaft 22 a hand wheel or crank 34 through the medium of which the apparatus may be readily actuated by hand.

Suitably keyed to the driving shaft 18, at the inner side of each support 11, is a sprocket wheel Each of the sprocket wheels 35 is in vertical alignment with an idler sprocket wheel 36 arrangcijl at the inner side of the upper member 13 immediately thereabove, and said idler wheels 36 are suitably keyed to stub shafts 37 journalled in bearings 38 which are connected to and extend through said members 13. A sprocket chain 39 is trained over each of the sprocket wheels and the idler sprocket wheel 36 associated therewith, said chains 39 and the article-carriers, to be presently described, constituting an endless conveyor for the storage and display of the merchandise. These chains 39 are of the usual construction employed in chain and sprocket gearing, including the customary male and female link connections, and as they travel over the sprocket wheels 35 and 36 the merchandise supported by the several carriers is transferred from one stretch to the other stretch, thereby permitting the merchandise readily to be inspected as the same may pass any given point. Furthermore, by such construction the merchandise may be compactly stored in the apparatus, and when such merchandise is in the form of wearing apparel, whether ladies garments or those of men, it may be readily removed from the apparatus and replaced therein when such may be desired.

In carrying into effect the present invention, it is highly desirable that the articlecarriers shall be maintained in vertical relation as the same traverse the path of movement which they follow, and particularly so when they are transferred from one stretch of the conveyor to the other stretch thereof. For the accomplishment of this the transfer mechanism now to be described is employed. It includes upper transfer sprocket wheels 10 and lower transfer sprocket wheels 41, the upper and lower transfer wheels being in alignment with each other, but being offset with respect to the sprocket wheels 35 and 36 of the conveyor. The upper wheels 40 are suitably connected in fixed relation to stub shafts 42, while the lower wheels 41 are suitably connected to stub shafts 43. At the outer ends of the shafts 42 are mounted sprocket pinions 4i, and similar pinions 45 are mounted at the outer extremities of the shafts43. Each of the upper sprocket pin- Cir Ill]

At the outer ends of the driving sha'l't 18 are tinediy connected sprocket pinions 48.

which are in line with the pinions lf) carried by the shafts 43, and sprocket chains 4-9 are trained over the pinions 4E5 and 48. Thus it will be seen that in the operation of the conveyor the shafts 37 will actuate the shafts 4:2 by means of the chains :7, while the shaft 18 and the sprocket pinions 48 carried thereby, through the chains 49, will actuate the shafts 4.3. This imparts movement of the sprocket wheels to and ll in unison with the movement of the sprocket wheels and 3 To insure the proper decree oi tension to the sprocket chains l and 4-9, and to take up any sl ck therein which may arise by wear thereon, a sleek adjusting block 50 is pivotally niountcd contiguous to one stretch of each of these chains. These blocks 50 are provided with eccentric faces, and when the blocks are adjusted on their pivots the chains at? and 41:9 may he tightened to the required extent.

For taking up slack in the chains 35) is the purpose of the sectional construction oi? the supports 11. W hen such SlZtUkIlOSS arises in the chains the bolts 15 are loosened. and the upper members 13 are moved in an upward direction with respect to the members 12, thereby tightening chains 39 to the required extent. At such time the space intervening the continuous ends of the members 12 and 13 may he filled with a spacing block 51. In this connection it is onserved that the proper alignment of the member 13 with respect to the i'neinher 12 of each of the supports should be preserved, in order to provide :tor proper alignment of the various sproclstct wheels and chains, and to this end each of the members 123, at its outer face, is HJOVltlOtl with a. longitudinally extending; gruide an .i 52, the lower ends of these arms overlzu ping the upper ends of the nienihers 12, as readily seen in Fig. 2. These arins also serve as spacing nieinbers, andv they are vertically aligned with similar spacing members 53 arranged at the outer :laees ot the n'ieinhers 12 of the vertical supports 11.

Each stretch of the chains 39 travels in a tl-shaped guide 53, said guide being in the tern: of a channel iron and the chains there by are prevented ino *ing from a vertical line in both the upward and downward mover cnt ot the stretcl'icsl This serves the dual purpose oi? nniintaiuing the stretches oil the chains in proper relation to the wheels 85 and 36, and also of preserving the vertical position of the article-earricrs, and preventing the latter troin swaying or swinging as they traverse their path of movement. The

carriers may be of varied construction and form, and either may he in the term of supporting bars or shelves. The preferred enibodiuicnt oi the carrier is shown in detail in Figs. 7, 8 and 9. It includes a pair of suspended linhs 5st, said links also being; in the 'lorin ct channel iroln andha'ving keyhole slots 55 in both their hody portions as well as their flanges. The upper ends of the links 54: are pivotally mounted on supporting rods 56, as by per-iterated hubs 57, the ends ot the rods 56 being suitably secured in the links of the chains 39, and held therein as by fastening nuts 58. Thus the upper ends (it the links rovidc points on which the links niay readily swing; while the lower ends of the latter are free. These ends, however, also carry supporting rods 59 at the extremities oil which are mounted anti-trio tion rollers (50, and said rollers (50 also are designed totravel in the channel guides 53 in the movement of the conveyor.

lixtei'iding over the upper edges of the sprocket wheels 40, and arranged at the inner sides of the members 13, are arcuate guide plates 61, cinijtorining generally to the radius of the wheels 40. The purpose of these plates 61 to guide the lower ends of the links Set as they pass from one stretch ol the conveyor to the other. But it necessary to insure proper thrust or throw of the lower ends of the links 5st in unison with tie movement of the upper ends thereof as these upper ends pass around the idler sprocket wheels 36. For this purpose each of the links 5 1- is provided near its lower end vith an inclined contact spur (52,and at one side of one of the guide channels 53, at a point adjacentto each wheel ll), each of said guide channels 53 is provided with a downwardly flared deflecting lip (33. In the upward travel of each of the links 5*]: the contact: spur (32 thereo't will engage the deflecting lip 03 at the llll'iQ that the upper end oi the link 54: is about to pass around the adjacent wheel El, and as the link til; continues to rise the inclination of the spur 62, as the latter moves over the deflecting lip 63, forces the inner end (it the link 5-linwardly and causes the anti-triction roller (50 at the adjacent side of the link to enter one of the notches between two teeth of the sprocket wheel elO. \Vhcn the roller 60 thus has been introduced between the teat-h of the sprocket wheel it will be seen that the rotation of the latter causes the lower end of the link 54 to move in vertical alignment with the upper end of that link as the latter rounding); the sprocket wheel 36. and the contiguous guide plate 6i. directs the movement of the lower end ot the link until the latter reaches the ()Dl'nhaltd stretch. of the conveyor and begins its downward increment. 'lhereupon, the rollertO enters the guide are arcuate guide plates 64, held suitably in position through the means of fastening tongues 65. These guides 64 establish a path of movement for the anti-friction rollers 60 when the lower ends of the links 54 reach the wheels 41. A such time the rollers 60 will enter spaces between two adjacent teeth of the wheels 41, and the rotation of the latter moves the lower ends of the links 54 from the descending stretch of the conveyor over tothe ascending stretch thereof, the vertical position of the links 54 thus being preserved atthelower end of the conveyor as the links are transferred from one side thereof to its opposite side.

It is essential in the operation of the apparatus hereindescrioed that the uni-directional movement of the conveyor chains 39 shall be maintained to insure the "ertical hanging of the carrier links 54. For this purpose a pivoted pawl 66 is arranged at the inner side of each of the supporting members 12, said pawls co-operating with the teeth of. the sprocket wheels and preventing reverse movement of these wheels. The pawls 66 are arranged above the wheels 35 and act by gravity in relation to the wheels 35. r

The guide channels 53in which the descending stretches of the chains 39 are located are each provided with a curved guide lip 67 against which the rollers are designed to contact to direct the same into the channels (33 as they begin their downward movement.

It has been stated that varying forms of supporting devices may be used for the storage and display of the merchandise. If the latter is to be suspended on the carriers, as

in the case of clothing, simple suspending bars (58 may be employed. The ends of said bars are formed with headed fastenings 69 adapted to enter and be engaged with the keyhole slots in the body portions of the links 54, and thus while the bars 68 may be readily detached from the links, they are ings Flare caused to engage the keyhole slots 55in the flanges of the links 54:, through which medium the arms 'TOare detachably connected to said links. Shelves 72 are associated with the arms 70, and thus provide the requisite extended supporting surface as" may be required by the nature of the articles to be stored and displayed. The arms 70 may either be horizontal or inclined as illustrated in Fig. 8, according to the most effective display which it is desired for the articles carried by the shelves 42, and in either construction the relatively broad surfaces of the shelves 72 afford display at opposite sides of the links 54.

The operation of the hereindescribcd display apparatus will be readily understood from the preceding description, and briefly described is as follows:

When pressure is applied to the foot lever 30 the brake lever 27 is released from its frictional contact with the brake drum 26. Thereupon, the electric motor 25 becomes energized and through the gearing interposed between the motor and the driving shaft 18 rotation is imparted to that shaft. \Vith the operation of thc shaft 18 the conveyor, constituted by the chains 3!), the sprocket wheels 35 and 36 over which said chains are trained, and the article-carriers, is given the necessary driving movement to cause the merchandise stored on the conveyor to rise on one stretch thereof and descend at the other stretch. The rate of movement of the conveyor obviously is controlled by the ratio of the gears. the best effect of the apparatus being attained by relatively slow movement of the conveyor. As the merchandise passes a given point, the observer can determine the character thereof and the price thereof, if the pricing be displayed on the merchandise. As each of the carriers reaches the upper end of the conveyor the upper ends of the links 5% thereof pass around the wheels 36, the lower ends of the links being deflected in ardly and into engagement with the teeth of the wheels 40. As the latter rotate the lower ends of the links 54 follow their movement in unison with the movement of the wheels 36, and the upper ends of the links 54 travel in connection therewith until. the opposite stretch of the conveyor is reached and descent of the carriers begins. In that movement the lower ends of the links 54, being still in vertical alignment with their upper ends, enter the guide channels 53 at the opposite side of the conveyor and descend to the lower end of the latter where they pass around the wheels 41, and are transferred to the ascending stretch of the conveyor. But in the entire path of travel of the articlecarriers their vertical position is maintained, and the merchandise stored and displayed thereon is maintained in proper relation thereto.

During the movement of the wheels 3.") the gravity pawls ()6 ride over the teeth thereof alternately dropping into the spaces between adjacent teeth, and thereby locking these wheels against reverse movement. This insures uni-directional movement of the conlltl Ill)

stood that any suitable nechan in may be veyor and precludes injury thereto which might arise incidental to such reverse move ment.

The operation of the apparatus continues so long as the electric motor energized and the brake lever 27 is out of frictional contact with the brake drum 26, The foot lever isthe medium for maintaining this relation of the parts, but it will be unden adopted for locking the parts such position as to insure continuity of operation of' the apparatus for any predetermined period of time, thus avoiding the necessity of maintaining pressure on the foot lever 30 by an operator of the apparatus.
