Specification of Letters Patent.

Patented Nov. "3, 1916.

Application filed January 12, 1915. Serial No. 1,833.

To all whom it may concern:

Be it known that we, FREDERICK LENG- QUIST and learns P. WILEs, citizens of Sweden and of the United States, respectively, residing at Joplin, in the county of Jasper and State of Missouri, have invented new and useful Improvements in Display-Racks, of which the following is a specification.

The general object of this invention is to overcome the necessity of removing receptacles which have hinged closures from the shelves of display racks, in order to raise the closures or covers when it is desired to gain access to the interior of the receptacles.

A further object of the invention is to prevent the unauthorized raising of the covers of receptacles when the display rack is in display position.

Other objects will appear and be better understood from that embodiment of our invention of which the following is a specification, reference being had to the accompanying drawing, in which- Figure 1 is a perspective view of the display rack. Fig. 2 is a side elevation of the view shown in Fig. 1. Fig. 3 is a side elevation of the display rack showing the shelves of the rack moved from their normal superimposed relation to stepped relation.

Referring to the drawing the support for the display rack includes a pair of standards 1 and 2, each of which comprises a base section 3, a top piece 4, and a pair of spaced uprights 5, connecting the top piece to the base section, one upright of one of the standards being connected to the corresponding upright of the other standard by means of the cross bar 6. The top pieces of the standards support a stationary shelf 7 which has its opposite ends secured to the respective top pieces and is provided adjacent each end with a pair of slots 8 opening into the ends of the shelf.

Disposed for swinging movement below the stationary shelf 7 is a shelf 9, said shelf being connected to the top pieces 4: by means of depending pivoted supporting rods 10, the lower ends of which are connected respectively to the opposite ends of the shelf 9 and to points adjacent the front longitudinal edge of the shelf 7.

Located bove the stationary shelf 7 is another shelf 11, said shelf being adapted to have swinging movement with respect to the stationary shelf and in an opposite direction to the movement of the shelf 9. The

shelf 11 is connected to the support by means of diagonally arranged supporting bars 12, which have pivotal connection with the opposite ends of the shelf 11 adjacent the rear longitudinal edge thereof, and which have their lower ends extending downwardly and pivotally secured to the rear ends of the top pieces 4 of the standards. The upper ends of the supporting rods 12 are extended above the shelf 11 and support a cross piece 13 which extends in parallelism with the shelf 11 and is designed, as shown in Figs. 1 and 2, to engage the covers of the receptacles supported by the shelf 11 and prevent the covers from being raised when the dis play rack is in display position, as shown in Figs. 1 and 2.

In order to prevent the shelves 9 and 11 from tilting when supporting the various receptacles, rods 14, 14: are provided. These rods extend through the slots 8 in the stationary shelf 7 and are pivoted therein as shown at 15, 15, and have their upper ends pivotally connected to the opposite ends of the upper shelf 12, adjacent the front edge thereof, and have their lower ends pivotally connected to the opposite ends of the bottom shelf 9 at points adjacent the rear ends of the shelf. These rods 14 serve to prevent tilting of the shelf when in the act of supporting the receptacles, and also serve as stops for limiting the swinging movements of the shelves 9 and 11 by engaging the front wall of the slots 8, as shown in Fig. 3.

It will be observed that when the shelves are in displaying or superimposed position, as shown in Figs. 1 and 2, it will be impossible to raise the covers of the receptacles thereby preventing unauthorized access to the interior of the receptacles unless the latter are removed from the shelves. When it is desired to gain access to a receptacle, the shelves of the rack are moved to a position where they lie in stepped relation, as shown in Fig. 3. This may readily be accomplished by pushing backward on the upper cross piece 13 until the shelves and cross piece have cleared the covers of the receptacles.

What we claim as new is In a device of the kind described in combination, a pair of spaced apart standards, a horizontally-disposed top piece secured upon each standard, a pin projecting from the inner side of each top piece, a link rod centrally fulcrumed upon each pin, a pair of flat longitudinal platforms arranged respectively above and below said top pieces, one of said platforms being pivotally secured to the upper ends of said link rods and the other platforms being pivot-ally connected to the lower ends thereof, a pair of pivotally suspended supporting bars secured to said top pieces and pivotally connected to the platform below said top pieces, supporting bars pivotally connected to said top pieces and to the platform thereabove,

and a fixed shelf secured With end edges Copies of this patent may be obtained for against the inner sides of said top pieces, said shelf being formed upon its opposite end edges with alining rectangular recesses 15 against either of the parallel edges of Which said link rods may incline and be supported.

In testimony whereof We afiiX our signatures in presence of tWo Witnesses.
