struction adapted for holding goods for display or for storage including a series of vertical sections forming units adapted to be interlocked to each other and'provided with shelves adjustable to varying positions on the sections.

One of the leading objects of the'invention is to provide-a sectional case and shelving construction for which the units are provided with improved means for locking one unit to the other against horizontal movement.

Another object of the invention is to provide a sectional shelving construction or sectional case embracing a plurality of interlocking sections adapted to be arranged in knock-down fashion for shipment in a very compact condition and so constructed that there will be no necessity for breakage in disassembling the shelving or case, and consequently a minimum amount of lumber will be required.

A still further object of the invention is to provide a sectional shelving or case construction including a series of frame supports and a series of connecting members adapted to interlock the said frame supports and to inclose goods arranged within the case or on the shelves so as to protect saidgoods against dust and other destructive influences.

With the above and other objects in viewthe supports therefor; Fig. 3 is a bottom plan view; Fig. 4 is an end view with one of the end panels removed; Fig. 5 is a detail perspective view on a reduced scale,'of one of the end panels; Fig. 6 is a detail perspective view of one of the members of the case; Fig. 7 is a detail perspective view partly in section showing the lock between the end panel and the vertical supports of the case; Fig. 8 is a detail perspective view of one of the supports of the case showing the constructionof one of the locking members or tongues; Fig. 9 is a detail perspective view of one of the locking connections between the shelves; Fig. 10 is a detail sectional View taken on the line 10-10 of Fig. 1;Fig. 11 is a 'detail sectional perspective view of a pair of tongues for locking the back panels of the case or shelving; Fig. 12 is a detail perspective view of one ofthe locking lflanges carried by the top connecting mem- In the accompanying drawings, I have illustrated a sectional case or shelving construction comprising three vertical supports, which are formed of angle irons and which are adapted to be interlocked to the horizontal supports. A greater or lesser number of the vertical supports may be employed, if desired.

The central vertical supports consist of rear angle bars 5 and 6, which are joined together so as to provide rear flanges 5 and 6. The rear angle bars 5 and6 are connectedto the front angle bars 7 and ,8 by means of the horizontal angle iron shelf supports 9 and 10, which horizontal shelf supports 9 and 10 are spaced apart'from' vertical strip 14, preferably of wood. The

end vertical supports are also formed of angle bars arranged in contacting pairs. The rear pairs include angle bars 15 and 16 and the front pairs include angle bars 17 and 18. The rear angle bars 15 and 16 are connected to the front angle bars 17 and 18 by means of the horizontal anglejib'ar shelf supports 9 and 10. The rear angle bar supports 16 are provided with flanges 16' formmg tenons and the front anglea'bars 17. are provided with flanges 17 forming tenons, which tenons are adapted to enter the vertical grooves 19 formed in theend panels 20. The end panels 20 are provided with tongues or arms 29 which are formed with notches adapted to engage the tongues 31 stamped out of the flanges 16 as shown in Fig. 8. The end panels 20 are provided with cross pieces 21 arranged near the upper and lower extremities thereof, and which carry depending metallic arms 22. The depending arms 22 are adapted to engage the horizon tal shelf supports 9 and 10 and enter the spaces 12 between said supports 9 and 10, as shown in Fig. 9. In this way the end panelsare locked to the horizontal shelf supports and to the vertical supports. The front supports 17 and 18 are fixed 'to vertical wood strips 23. g

The lower horizontal shelf supports 9 and 10 are enlarged at their ends to receive screws 24 adapted to prevent pivotal movement of said supports on the lower end of the vertical angle bar supports and the upper horizontal supports 9 and 10 are constructed the same way as the lower horizontal shelf supports and for the same purpose. The horizontal shelf supports 9'and 1O support the shelves 25, which are provided at their ends with depending flanges or arms 26 adapted to enter the spaces 12 between said supports 9 and 10. I r

The central rear vertical angle bar supports 5 and 6 are provided with rearwardly extending right angular flanges or tongues 27 stamped out of the flanges 5 and 6' and the flanges of the rear angle bar supports 15 are provided with right angular tongues 28 stamped .out of the rearmost flanges thereof. The tongues 27 and 28 form holding tongues for the back panels 32 which are formed with edge grooves 33, whereby said back panels may be forced into position between the tongues 27 and 28 as shown in Fig. 3. The upper and lowermost shelves 25 are provided with depending flanges 35 adapted to enter the upper edge grooves 36 formed in the back panels 32. The lowermost shelves 25 may be connected to the front or facing strips 88, which are provided with end tongues 39 adapted to engage the tongues 40, and the uppermost shelves 25 may be connected with the upper facing strips 41 which are provided with end tongues 42, which are notched to engage the tongues 43, as shown in Fig. 1. Doors 44 are hinged at 54 to the strips 23 and are adapted to close against the central stri 14. If desired vertical or horizontal slidin doors may be used'instead of the swinging doors. An ornamental top piece 45 is removably mounted on the upper end of the case or shelving so as to more efiectively protect the same and improve its general appearance.

By means of the improved construction all of the parts can be formed in predetermined factory sizes in the manner that seetional book cases are now constructed, and can be shipped in disassembled form to the distributing points or buyers. After being received they can be readily assembled with the aid of a screwdriver and without the necessity of any carpenter work. After being set up they can again be disassembled or knocked down without the necessity of breaking any of the parts, and in this way no lumber will be wasted and the parts can be repeatedly used. When the members of the shelving or casing construct-ion are connected together the interior of the shelving or case will be protected against dust and other destructive force, likely to cause a deterioration in the goods. In this way lumber that is now destroyed in erecting shelving and store cases can be applied in a more economical manner, and since the supply of lumber is decreasing and its cost correspondingly rising the invention provides for the conservation of lumber. WVhen it is desired to arrange the shelves in tiltin positions a brace 25 is pivoted to the horizontal shelf sup orts 9 and 10 and to one set of the vertica angle bar supports, as shown in Fig. 4.

Having thus described my invention, what is claimed as new is:

1. A sectional shelving construction comprising a series of vertical angle bar supports arranged in contacting pairs, a series of shelf supports adjustable on said vertical supports, shelves adapted to be locked to the shelf supports and to be adjustable therewith, and lateral tongues extending from a part of the vertical supports and end panels provided with locking devices having notches adapted to engage the tongues.

2. A sectional shelving construction comprising vertical angle bar supports arranged in cont-acting pairs, a series of horizontal shelving supports adjustable on said vertical angle barsupports, a part of said vertical angle bar supports having flanges forming tenons, vertical members secured to the supports and end panels having vertical grooves adapted to receive the tenons and be interlocked with the angle bar supports carrying said tenons.

3. In a sectional shelving construction, a series of vertical angle bar supports, vertical members secured to said supports, the end vertical angle bar supports being provided with lateral tongues, a series of horizontal shelf supports adjustable on lthe vertical end angle bar supports, a series of end panels having grooves adapted to receive portions of the end vertical angle bar sup ports, and notch locking device secured to the end panels adapted to lockingly engage the tongues of said vertical end supports.

4. A shelving construction including ver tical supports, shelving supports adapted to be secured at either end to the vertical su ports, and braces pivoted medially of te shelving supports and adapted to be secured to the vertical supports for holding said shelving supports in inclined positions and adapted to be secured to either set of the vertical supports, whereby the shelving supports may be inclined in either direction.

5. In combination, a series of vertical supports formed of angle iron, means for connecting the supports in spaced relation, and a top shelf adapted to be interlocked to said connecting means and having a depending flange on its rear edge.

6. In combination, a series of vertical supports formed of angle iron, horizontal angle bar shelf supports connecting said vertical in presence of two witnesses.
