c. J. WHITE FLORAL RACK NSW, 4, 1947,

r' Filed Aug; 21, 1944 Patented Nov. 4, 1947 UNITED STATES `'PATENT OFFICE Claims.

This invention relates to improvements in floral racks.

More particularly the invention has to do with fioral racks of the collapsible type such, for example, as that shown in my Letters Patent No. 2,115,693, issued April 26, 1938, wherein a series of impalement prongs are pivotally attached to certain of the members of the rack which by gravity fall to position between certain other members to .receive floral pieces when the rack is extended, and which may close by gravity to permit the rack to be collapsed.

The object herein is to provide means for positively operating the prongs in the closing movement of the rack parts, or Without depending upon gravity for prong movement, said means being such that the operator inthe act of collapsing the rack will become conscious of the fact, if the operation is faulty, that an obstruction behind a prong may 'be preventing closing of the same.

A further object, also, is that should an obstruction be present behind a prong the said means will set up a force contrary to that applied by the operator as -a notification of trouble to the yend that the rack parts will not be strained. That is to say, the counterforce will `be such that further pressure by the operator must be halted until the obstruction is removed.

To the end that the invention may be understood the appended 4drawing 1is provided .forming part hereof wherein Figure 1 is a iront .elevation `of a `floral rack' of the type named.

Figure 2 is 'a detail of part of the rack of Figure A1, much enlarged, thisalso being a front elevation.

Figure 3 is 'an 'enlarged detail of parts shown in Figure 2 as 'shown in side elevation.

Figure 4 is a side elevation of rstill other parts, portions being shown in section.

Figure 5 is a transverse section of part of the rack and parts associated therewith.

Figure 6 is 'afront elevation ofthe parts shown ijn'Figure 3.

Figure 7 'is a sleeve shown iin perspective..

Figure '8 shows in fp'e'rsp'ective a prong .shownin other figures.

Figure 9 Yis aa iront elevation impart section :of certain -other parts ofthe structure.

Figure `9a shows in perspective part `of a `ro'cl in detail, and

Figure '1'0 is a side 'elevation of the same parts shown in Figure '9, also 'in part section.

moved to a substantially horizontal position in order to cause the impalement prongs to fall by gravity away from between certain members of the rack to permit full closing or collapsing of Athe latter, the .present improvement causes the said prongs to be automatically withdrawn from between said members and to be Vheld snugly against the members on which they are pivotecl as will appear.

While said patent illustrates means for positively swinging a prong on its support said means is of a type applicable only to a certain part of the rack whereas in the present application a more simple arrangement Ais employed to accomplish the purpose.

In the drawing hereof I denotes in this instance each of three supporting members lying parallel to each other serving as standards for the whole structure to be described, and though not shown the whole may be 'provided with .a rear supporting structure after the manner .of an easel.

These said members l may .each be of rectangular form in cross section, in this instance only, a front 'face of' which has a groove 2 extending longitudinally thereof, see Figures 4 and -5 to kreceive an yelongated part such as a rod 3., for example, shiitable lengthwise therein.

Forward of these vmembers isa structure of a lazy-tongs arrangement consisting of crossed members 4, f5 as in Figures 1 and 2, these being pivoted upon each other where they cross as indicated at a stud E extending from a part such as a sleeve 1, for example, on leach member l, also as :suggested in said Figures =4 and 5, so that in the collapsing movement of all of the parts named the sa-id sleeve is `free to shift along said mem-ber i, except, however, as to those sleeves Whereas in the use of the rack of my above named patent it 'is -required "that said rack be which lie on the dotted line a-a, for example, Figure 1, which :are `iixed to the members I on which they 'are mounted in order that jointly with'the members 4, 5 the rack Will be stabilized in vall respects, the balance of the said sleeves, however, shift with respect ato those thus liixed in place.

.lt will :now be seen that :in :collapsing the lazytongs structure 'the -slldable sleeves 'at position above and 'below the zxed sleeves `will shift in opposite directions.

Pivote'd to the members fl atclesired intervals at the 'openings between the ymembers 4, 15 is a series o'f'impalementprongs one of which isillustratecl in Figure '8, see also Figure 3. vEach includes a pair of :spaced ears 9 lthrough which, and the member il, extends fa ipin I0. 'The prongs are so pivoted that 1in ra, `1subs'ta'ntially upright position 3 of the rack they will fall forward through the spaces between the said cross members 4, as shown in FigureS in broken lines.

It is noted that the heel of each prong may include an extension II which substantially abuts the face of a member I when the prong is in the position named. Also it is observed that said eX- tensions may be outwardly curved and that so curved or bent it lies in the path of movement of a plate or tab I2 or equivalent means on a named rod 3, said tab normally lying below and spaced from the extension II when the rack is in upright position, i. e., when said prong is extended.

Referring now to Figures 9 and 10 it Will be seen that the groove 2 which may be uniform in width throughout a member I may be enlarged into a cavity 2, said cavity being at the upper limit of said member. The upper end of the rod 3 extends into said cavity and has an abutment 22 thereon within the latter above which, and resting thereon, is a portion such as a collar I3 slidable on said rod above which is a spring I4 encircling the rod and lying between said collar and an abutment I5 of the rod. The named abutment 22 may be of any type such, for example, as a flattened and spread portion of the rod as in Figure 92'-,

The uppermost sleeve I of one or more of the members I has an inturned extension '12, Figure 7, which extends into the slot 2 to travel therealong. This extension is adapt-ed to engage beneath the collar I3, Figure l0, and move it in a direction to compress the said spring I4.

Figure 2 illustrates in both full lines and broken lines the manner of ,collapsing the rack, the dotted lines b, b denoting the abutting position of the members 4, 5, and their alignment with the adjacent member I.

As stated, the prongs 8 are extended through the spaces between the members 4, 5 into and beyond them in the erected position of the rack.

The act of collapsing the rack naturally moves the extremities of the said member 4, 5 farther apart and therefore the upper extremities carrying the sleeves I which have the inturned extensions 'I2 will, by the latter in its travel engage beneath and lift the collar I3 thereby lifting the rod by pressure against the spring.

The raising of a rod also results in moving the tabs VI2 of the rods upwardly to abut upon and close the prongs adjacent each of the latter against the member I.

At such a time should the stem of a ilower or some other obstruction chance to lie behind the prong the collar I3 will compress the spring. The operator upon noticing a force counter to his action is clearly aware of some such obstruction and knows that it must be removed, and he is also aware that undue strain on the parts of the rack may result if he uses further undue force.

When the rack is totally collapsed the prongs lie against the members I, and the springs are under such compression that said prongs are iirmly held in abutment with said members entirely out of the paths of travel of the members 4, 5. The spring compression continues until the last named members of the rack, as the latter spreads, are in such positions that the prongs are free to fall outwardly clear of said members 4, 5 at which time, of course, the tabs I2 have moved from prong engagement. Thus, together with the actions already described the prongs are never in interfering positions during rack adjustments.

While a preferredstructure is illustrated and described herein other equivalent means may be used such as would lie within the meaning of the invention `and within the scope of the claims to follow.

I claim:
