This invention lie-lates `to `srtile-suppoJrting racks, `and more partielllrly to .a ,display .raek such as vmay be used for holding floral despretions in churches, funeral parlors, etc.

Accordingly, as shown in Figs. 3, and 6, the lower members I2 of the uprights are provided with elongate apertures I2a in their walls, preferably uniformly spaced longitudinally, and a plurality of cross-bars I3 are provided, the ends of the bars being of a size and shape enabling them to nt into the apertures I2a and having notches I3a forming hooks. By this construction the cross-bars I3 may be hooked into the lower members I2 of the uprights, as shown in Figs. 2, 5 and 6, to connect the latter together in their assembledpositions. AsV shown inFigs. 2 and 4, the .upper` members II of the uprights are also provided with apertures, designated IIa.
for receiving other cross-bars I3. However, the` apertures IIa which are in the lower portions of.
the members II have definite predetermined po'- sitions with respect to the aperturesV IZa located in the upper portions of` the members ,12. Re-4 ferring to Fig. 5, an aperture IIaI is provided-in l the lower portion of one of the members Il in such a location that it aligns with that aperture 12a of the enclosing member I2 which is located immediately above the lowermost' cross-bar I3 when the lower end of the member II is in position to rest on the end portion of this crossbar, as shown in Fig. 6. Both uprights Ill are constructed in this manner. By this arrangement, referring to Figs. 2 and 5, the second lowestcross-bar I3 may securely hook into both the members II andV I2, and by Virtue of` the close clearances provided, may prevent sidesway of the rack. Yet the bar I3 may be easily removed at any time by merely lifting it at both ends, and shifting it one way or the other to move one end first out of the 'aligned apertures IIa and IZa. As shown inv Fig. 4, the cross-bars I3 connecting together solely the upper members II may be' also conveniently removed in the same manner. Since, however, the weight of the members II are carried bythe'ends of the lowermost crossbar I3, the latter isto this extent locked, in its hooked position against accidental removal. By this construction there is avoided the use of small parts such as clamping screws andthe like, which may become lost, Orstripped after prolonged use, yet the assembled structure is sturdy and rigid for the purpose intended.
vReferring again to Fig. 2, only two cross-bars I3 are shown connected solely with the"upper members II of the uprights. However, Vby loeating the cross-bars inother apertures the Vdevice may be assembled so that three'cross-bars Vconnect solely with the members II and only vone. cross-bar connects with the members I2, in
whichevent the rack would be extended to a ,higher position, or Vthe rack may be assembled .in a lower position wherein one cross-bar may connect solely with the members II, and three cross-bars connect with the members I2. In
`either case, the connection of the lowermost cross-.bar I3 will be as illustrated 'in Fig. 6, wherein the members II rest on the end portions of the cross-bar to hold these in place, and
the connections, if any, of the highercross-bars vto the members I2 will be as shown in Fig.`5
wherein the apertures IIa and I2a of vthe respective members are aligned.
IA convenient way of assembling the-rack is 4to insert the lowermost cross-bar I3 in the lower members I2, insert the uppermost cross-bar I3 in bers I2 and II together until the lower end of the upper members I I, and then bring the mem-` Preferably, the lower ends of the members I2V are provided with feet I6 which may be of rubber or other suitable material and the upper ends of the members II provided with ornamental knobs I1 which may be of metal.
In a modification of the invention, shown in Fig. 8, the telescopic members of the uprights may be of square cross-section, the lower memberISbeing larger to receive the smaller upper member I3. The members I8 and I9 may be 1 formed of sheet metal with a welded dressed seam, or may be drawn in tubular form. The advantage of this construction is that if the members Iand I9 are initially telescoped with their apertured walls adjacent each other, the
apertures intended to align with each otherA to receive the ends of the next lowest cross-bar will be caused to alignor register automatically when the lower ends of the inner members rest on the lowermost cross-bar, since the inner membersdcannot turn with respect to the outer members. a `V 5 Another modication of the inventionV is shown in Fig. 9, wherein the crossmember 20 may beA made of'a material such as wood, and provided with hooks 2| of metal. These hooks may be attached'to the ends of the bars 20 by screws' 22,'and may be formed of. metal plates having notches 2Ia, the plates being of a size -and'shape to .t into the apertures of the upright members. Y Y
Another. modification of the invention is shown in Fig. '7, which illustrates an upright 23 Vcomprising a'lower member 24 and an upper member 25, each of rectangular section, Vthe members being made of wood or other` similar material. In this form of the invention the `upright members 24 Vand 25 arel provided with apertures ZIIaI and 25a. respectively which pass entirely through the members, the apertures being spaced so that the lowermost cross-bar I3 .is engaged by the upper wall 25h of the aperture 25a when',` the'upper` apertures 24a. and 25a are in alignment. Thus the end portion of the crossbar I3 supports the weight of the upper member 25 and is locked thereby Vin the position shown.. Y y. 4 The lower end portion 25e of the rnember25 is vprovided with aY strap clamp 26 which Vmay `embrace the member 24 to prevent lateralseparation of the members .while at the same time permitting longitudinal adjustment.
Byl using the construction of Figs. '7 and 9, a rack'- maybe made in accordance with the invention using all wooden structural members, as
may be readily understood.
