Referring more particularly to the drawings, in which like reference characters refer to similar parts throughout the several views, and to Figs. 1 and 2, the display case shown includes a wood base I encased in sheet metal 2, which may be of Monel metal or other suitable material, and uprights 3, see Fig. 3, at the rear of the base and suitably anchored thereto, the uprights 3 being encased in a sheet metal covering 4 which ris formed to include a vertical flange 5 against which a sliding door at the rear of the case may engage when closed.

In display cases of this general type as heretofore constructed, the partitions have been of cast metal construction or otherwise heavily built, or provided with metal retaining strips on the outside of the case to hold the glass panels in place combined with fastening devices that readily loosen, and the many disadvantages of such prior structures are overcome by the present invention which utilizes partitions formed of sections of light weight sheet metaljwelde'd "together to form each partition as an integral unit, the partitions beingrconstructed in such a fashion that the front vertical` and angularly arranged glass panels are held'in place by vthe top glass panel, only one .fastening element Vbeing required to hold the entire glass assembly in position, ex-

cept at the corner partitions where a slightly different arrangement is required, as will be described hereinafter.

Fig. 1 shows the partition construction at one end of the case, with the glass panels extending only on one side thereof, whereas in Fig. 2 is illustrated an intermediate partition with the glass panels extending on both sides thereof. Each partition includes a top horizontal portion, a front vertical portion, and an intermediate angularly arranged connecting portion, all formed of light weight sheet metal and preferably welded together to afford an integral or unitary structure, the top portion of which is suitably anchored to the upright 3 and the front portion of which is anchored to the base I. The end partition includes an inverted U-shaped portion 6, see Fig. 4, which embraces the vertical end glass panel l, the U-shaped portion 6 terminating on the inside in a lateral flange 8 which supports the top horizontal glass panel 9.

Referring to Fig. 1, it will be understood that the sheet metal partition, including the portions 6 and 8 of Fig. 4, extends horizontally across the top of the case, thence inclining downwardly t'oward the front of the case, and extending thence downwardly vertically to the base, the end glass panel 'I being similarly shaped, and embraced along its top, inclined and front edges by the U-shaped portion 6. The lateral flange B is coextensive with the portion Ii and supports a top horizontal glass panel I0, see Fig. 2, the angularly arranged glass panel II, and the front vertical glass panel I2.

The intermediate sheet metal partitions are formed as shown inA Fig. 5, the inverted U-shaped portion i3 having flanges I4 extending laterally on both sides thereof to support the top horizontal glass panels l0 on both sides of the partition. The flanges I4 extend laterally on both sides of the inverted U-shaped portion I3 across the top horizontal part of the partition, thence incline downwardly toward the front, and extend thence vertically and downwardly to maintain the glass panels on both sides of the partition. With this arrangement, only the narrow outer strip of the U-shaped portion I3 is exposed to view, this being the metal part which divides or is located between the adjacent glass panels, the latter resting upon the flanges I4, and in order to maintain the glass panels in position against said flanges, the following structure is provided.

The front vertical glass panels drop down behind a flange I1 at the front of the base, see Figs. 2 and 14, the vertical panels being held at the bottom between said front flange il and the vertical ilanges I4 on the metal partition. At the top of the vertical portion of the partition there is provided an integral angular lug having a portion I8, see Fig. 10, extending forwardly and upwardly from the front wall of the metal partition and a portion I9 extending thence rearwardly and upwardly and terminating in line with the front wall of the partition, said portions I8 and I9 extending laterally beyond the central U- shaped portion I3, and overlying the flanges I4, in spaced relation thereto, as shown in Figs. 9 and 10.

This arrangement is such that in assembling the glass panels, the vertical panels I2 may be slid downwardly in a vertical plane between the vertical flanges I4 and the portions I8 and I9, and when the vertical panels are in place, their upper ends lie behind the portions I8 of the angular lug and are held in place against movement forwardly by the panels I I, while the flanges I4 retain them against movement rearwardly. A similar structure is provided on the metal partitions at the forward end of the horizontal portions, including an integral angular lug having a Vertical portion 2| and a horizontal portion 22 both extending laterally beyond. the inverted U- shaped part of the partition and so arranged as to maintain the angular and upper horizontal glass panels in place.

In assembling, after the vertical panels I2 havev been positioned, as already described, the angularly arranged panels are positioned by a sliding motion in the plane which they occupy on the supporting ilangesl4. Thus they slide under the vertical portions 2l of the retaining lugs, and when the angularly arranged panels I'I are in place, their forward ends lie beneath the portions i3 of the forwardiretaining lugs, see Fig. l0, and

- their upper ends lie under the portions 2i of the upper retaining lugs and also under the forward parts of the horizontal glass panels I6. The latter are assembled by a sliding movement in a horizontal plane, until they are positioned over the panels I I and beneath the horizontal portions 22 of the retaining lugs, which thereby hold `the panels II! and II in place against any vertical movement away from their supporting flanges.

The horizontal glass panels I6 are retained in position by a removable fastening member or lug 24, see Figs. 1 and 2, which isprovided ,with a suitable fastening bolt or screw that enters an opening 25 in a .plug 26 xedly located between the lateral walls of the U-shaped portion i3 at this point, see Fig. 6. The fastening lug includes `a vertical portion which overlies the end of the partition and a horizontal portion which seats in the recess formed by cutting away the top wall I3, as shown at 21 in Fig. 6. The fastening lug just described, when secured in place, overlies the rear edges of adjacent horizontal glass panels I6 and thus acts to retain the several aforementioned glass panels in place. When desired to remove the glass panels of the case for cleaning purposes, it is only necessary to loosen and remove the fastening lugs 24, following which the top horizontal lglass panels I8, the intermediate angularly arranged panels II,and the vertical front glass panels I2 can be'successively removed from their normal positions in the case by the sliding motions as already described.

The partitions are strengthened4 by bracing pieces or web portions 29 and 36 which are welded or otherwise integrally attached within the U- shaped portions I3 at the intersections between the portions in the different planes, see Figs. 2, 8 and l0. These web portions are located at the connecting points between 'the horizontal and inclined portions of the partition and between the inclined and front vertical portions. Each partition is anchored at the top to an upright 3 by means of screws or other suitable attaching devices extending through openings 3 I in the flanges I4, while the front vertical portion of the partition is anchored by a bolt 32 ilxedly attached to a block 33 which is welded or otherwise permanently secured to the lower portion of the partition within the U-shaped part I3, as `shown in Figs. 12 to 14. The'bolt 32 extends through an opening in the base and receives a nut 34 which secures the partition rigidly in place at the front of the base.

The structure thus far described has to do more particularly `with the arrangement of partitions and panels where the latter are `of rectangular form, that is, located at intermediate points between corner units, and in Figs. 16 to 28 is shown a structure such as employed at a corner where the meeting glass panels have their adjacent edges at angles of 45 to their opposite edges, as shown in Fig. 16. In this arrangement, the forward Vertical part of the partition comprises a metal post 35 which is anchored to the base by a bolt 36 and is recessed at its inner edge to receive the angle iron 31, see Fig. 26, which affords inner flanges against which the vertical glass panels 38 abut when in position. The angle iron 31 is welded or otherwise formed as a permanent unitary part of the post 35. At its upper end, the post 35 is permanently secured by welding or otherwise to the angularly arranged inverted U-shaped portions 39 of the partition which has lateral flanges 40 ,to support the glass panels 4I. Theflanges 48 are bent downwardly somewhat to extend parallel to the adjacent face of the corner glass panel when positioned thereon, see Fig. 36, and at its upper end, the angularly arranged U-shaped portion 39 is integrally connected to the top 42 which has the lateral flanges 43 to support the top horizontal glass panels.

The partition is anchored at the top by means of the screws 44 extending through openings in the flanges 43 and engaging the vertical post 45, see Fig. 21. The corner partition is braced by a web or reinforcing block 46, see Figs. 23 and 24, which is Welded or otherwise permanently attached'within the U-shaped portion 39 as shown. At the top of the forward post 35, the U-shaped portion 39 is formed to provide lugs at right angles to each other, as shown at Fig. 27, and each including a top portion 41 adapted to over-` lie the angularly arranged glass panel 4I, `and a vertical forwardlyinclined portion 48 projecting in front of the vertical panel` 38.` The corner lugs formed by the portions 41 and 48 extend laterally beyond the U-shaped portion 39, as shown in Figs. 22 and 2'7, and are formed as an integral vpart thereof, the arrangement being such that the vertical glass panels 38 can be positioned by l a vertical sliding movement between the flanges formed by the angle iron 31 and the vertical portions 48 of the retaining lugs. Following such positioning of the vertical panels 38, the angularly .arranged panels 4I are positioned as shown in Figs. 16 and 28 by a bodily movement downwardly upon the supporting flanges 40 and the corresponding flanges of the adjacent partition.

These angularly arranged corner panels cannot be positioned by a sliding movement, as in the case of the intermediate panels heretofore described, due to the fact that their two ends are not parallel. When positioned, the panels 4I are held at their lower edges against vertical movement by the portions 41 of the retaining lugs, and suitable removable retaining means is utilized to hold these panels at their upper ends.

In the present instance, this consists of a removable lug or fastening device of the form shown inFigs. 23 to 25 and including the horizontal portion 50 seated upon the block or web 46 and provided with a threaded pin 6I formed permanently therewith and extending through an opening in said block to receive a nut 41 on the inside of the case. This fastening device or lug includes downwardy extending portions 52 which overlie the front edges of the top horizontal glass panels, the top portions 50 being extended to overlie the top surface of said hori- Zontal panels, which in turn'overlie the upper ends of the angularly arranged panelsV to hold the same against vertical movement.

Where the corner glass panels are retained by a removable fastening device as just described, it is also necessary thatthe partitions `adjacent to the corner partitions be provided with a removablefastening device such as illustrated in Fig. 15, including a body portion 53, a threaded pin 54 fixed thereto to receive a nut on the inside of the case, and a lug 55. This removable fastening device takes the place of the integral lug previously described, and is made necessary on the partitions adjacent to the corner structures by reason of the fact that the glass panels are irregularly formed at their two ends and must be placed in position on their supporting flanges by a bodily downward movement, instead of sliding them into place under the retaining lugs, as previously described.l vWith this construction,l it will be noted that the fastening lugs referred to are held in place by nuts on the insideof 'the case, and since these are not accessible readily and cannot be reached except through the interior of the case, there is no likelihood of these parts accidentally loosening. The top horizontal corner panels 51 are held-in place by a removable fastening device such Yas illustrated in Figs. 18 to 20, which includes horizontal portions 58 overlying the adjacent horizontal corner. panels, and depending portions 59 whichroverlie-the in ner edges of the adjacent horizontal panels. This fastening device or lug'which isV of right angular formation, to cooperate with the two corner panels at right angles to each other, is held in place by a screw El, threaded into an opening in a block 62 which isY permanently attached to and carried by the U-shaped portion of the partition. To disassemble the corner glass panels, it is necessary to first remove thefscrew 6I and the fastening member held thereby, Aand also the nut 41, see Fig. 23, and the fastening member held by the latter. Similarly, the removable" fastening devices on the adjacent partitions are removed, whereupon the horizontal and angularly disposed glass panels can be lifted Vsuccessively, after which the vertical panels `38 at the front are removed by a vertical sliding movement. Y

The invention is designed so that a'complete display case may be composed of Va multiplicity of individual units, to be joined and secured together when assembled, and it lisessential that these separate units be accurately interlocked and maintained in their proper relationship,l in order that the glass panels can be readily and properly positioned. To accomplish. this, the adjacent units are provided with the interlock ing means illustrated in Figs. 29 to 35 inclusive. Figs. 29 and 30 illustrate the side and top of one' unit provided with interlocking means, and' Fig;

' 31 illustrates the adjacent unit to be alinedv with and secured to the irst mentioned unit; To accomplish this, one unit is provided on the u'nder surface of its basev with rplates 65 permanently secured thereto and provided With de'- pending lugs 66 which are cut away on one edge to aiford the angularrecesses 61,'while the other edge is tapered as at 68 and provided Vwiththe angular tapered portion 69, as shownin" Fig. 35; It will be understood that the part just described is inverted from the position shown in Fig. 35 when attached to the unit illustrated in Fig. 31, and engages the cooperating locking member byv a relative vertical movement... The adjacent unit of the case lhas 'ixedly attached thereto the plates 1l, each provided with a rectangular extension 'l2 spaced from its top surface to afford a recess or socket. 13 is an angular lug adapted to engage the aforementioned recess El of the mating locking member, and 14 is a tapered angular rekess to receive the mating lug 69 already described. When the display case unit carrying the plates 65 is placed downwardly upon the adjacent unit so that the lugs 69 and 13 engage the cooperating recesses 14 and 61, the two display case units are guided accurately into close fitting relationship With their meeting edges close together and alined. Thus the glass panel receiving partition that is carried by one of the units is properly positioned for cooperation with the panels on the adjacent unit.

The guiding and locking means just described establishes a correct and accurate relation between the adjacent'units from front to rear, and they are held together vertically by suitable means such as illustrated in Fig; 32, comprising cooperating threaded members such as a sleeve Y and bolt 'I6 and TI carried respectively by the adjacent uprights 'I8 and 19 of the two separable units. By this fastening means, the uprights are held securely together, preventing any spreading or separaticn'from top to bottom, and the two units are thus securely retained so as to insure the ready positioning and accurate locking of the glass panels. At the top, the metal partition carried by one unit is secured to the upright of the adjacent unit by a screw or other fastening means passing through an opening 89 in one iiange and entering the upright of the adjacent unit.

While the invention has been described with relation to certain structural details, it is not limited to the particular arrangements herein disclosed, and this application is intended to cover' such modifications or departures as may come Within the intent of the improvements or the scope of the following claims.
