(emu-s8)" .6 Claims.

Thisinvention relates to trays for supporting potted plants on window sills. An object of'the invention is the provisionof a tray for supporting potted plants on window sills, said tray being readily removable and being applied sesurely to the sill without the use ofnails or screws or any other kind of securing means which would disfigure the sill.

Another object of. the invention is theprovision of a tray for supporting potted plants on a window sill, the tray having means thereon for engagement with the usual hand lift appliedto the lower bar of a window frame for retaining the tray against displacement from the sill, said tray having suflicient surface contact with the sill to insure retention of the tray thereon when the retaining means is in engagement with the hand lift.

A further object ofthe invention is the provision of. a tray for supporting potted plants on a window sill, an adjustable arm being provided with a curved member adapted to be seated within the curved hand lift usually, applied to the lower bar of a window frame, said arm being slidably mounted in a. guide rising from and secured to the tray with means for secur ing the arm in an adjusted position, means also being employed on thearm and straddlingthe hand lift for preventing shifting of" the tray when applied to the window sill;

The invention consists in the novel construc+ tion, arrangement and combination of parts hereinafter more particularly described. and claimed.

In the drawings:

Figure 1 is-a view in perspective of a tray shown as removably applied to a window sill.

Figure 2 isa transverse verticalsec'tion of the tray through the removable attachingmeans.

Figure 3 is a transverse vertical section of a modified form of the tray and attaching means and Figure 4 is a fragmentary cross section through the window frame illustrating the sliding catch associated with the tray.

Referring more particularly to the drawings, i designates a lower window sash'havin'g the bottom bar 9 i equipped with the usual hand lifts I2. The sill l3- extends-inwardly into the room of a building in a horizontal plane.

The hand lifts I2 are formedintegrally with a plate i which is secured by means of screws -l to the inner 'fa'ceof the bottom bar H. The lifts are curved so that they maybe grasped comfortably by fingers of the operator. There are usually two lifts applied to each .bottombar of a window sash.

A tray, designated generally by the. numeral ZO-hasa bottom 2! which maybe flat or corrugated transversely as shown at 22. The tray has-vertically or angularly disposed sidewalls '23 and24 with theupper free edges. rolledasshown 2. at 7.501: the ireeledg'es maybe reinforced in any approved manner, as with a wire-stifiening means. I

A guidedesignated generallyby the-numeral 30 has a right-angular base- 3.! which is riveted or spot-weldedat 32 tothe inner surface of the bottomof the tray 20. with the guide in. flat contact .withthei-nner wall 23 of the tray; The vertical side edges 33 of the guide areinturned to provide in effect a pair of parallel groovesto receive the side edges of. anarm 35. The guide has acentrally disposed vertical. slot 3 6-for a purpose whichwill be presently, explained.

The arm 35-.also hasavertical slot 31. which alineswith the slot 36 .A threaded bolt-38 hav ing ahead39- whichis in contact with the. inner face of the arm is.-received..=by the slots 36 and 31. A: winged nut 40-threaded onto the outer endof-said bolt clampsthe arm 35 .in an adjusted position on the guide 30. v The upper free end of thearm 35-.hasamember 4! which is curved to. conform to the curvature of-the hand'lift 121 so that said curved member will fit neatly into said hand lift. A pair of spaced ears 42 formed integrally with the curved member 4| engage opposite edges of the member 'izi'and prevent rocking movement of the arm 35' and likewise the tray 20when 'saidtray is in an operative position on the sill I 3.

The tray is placed orr'the sill asillustrated -with the-- inner longitudinal wall '23 in close association with the botto'm'bar -|l ofthewindow sash l0 and with the curved member 4| in vertical alinement' with the hand lift 12'. The winged nut 40 has been loosened so that the arm 35 may be moved downwardly into th'eguid'e 30 to '-permit the reception of the-curved member 41 within the hand lift I 2.

With the inner wall 23 of 'the s'hel'f in theposition shown in'Figmes I and Z, where said wall is in snug engagement withthe bottom bar H of the window frame Hi, the arm is drawn upwardly and the: curved member 4| is forced intosnug engagement with thehand lift [2 with the ears-M engaged upon opposite sides of the hand lift. The nut dois thentightened. The tray 20 -is-ready foruse.

A modified form of theshel'fis illustrated in Figure 3. A- spring arm 3 designatedgenerallyby the numeral w has a" vertical portion 5| rising from a base' member '3"l-a which" is riveted or spot WeIded at 32 tothef corrugated bottom 22 of the -sheif 2 0 The remainder 'of the arm in the-form of: an ogee152: The curved freeend 53 engages ;beneath:the2-'curved.:hand=-litt: i=2 on the bar: it of the frame I'll; with thespaced ears. formed integrally on said free endrreceiving the hand lift.

Thermodified form". of 1 trayplaced in" posi+ tionby sliding the tray 20:. toward; the: :bar T with the bottom zofitheitray riding :on the: sill .13 until theifree end Semi the-spring amrsil con;

tacts the hand lift [2. The free end 53 is then snapped into position under the hand lift I2 while the tray is shifted to its final position shown in Figure 3. The free end of the spring arm may be assisted into position by applying pressure to a substantially horizontal position 54 of said spring arm.

The tray 20 in Figure 3 may also be placed in position by inserting the curved free end 53 of the spring arm 50 into the curved hand lift 12 with the tray tilted at an angle to the horizontal surface of the sill I3. The tray is then moved inwardly with the inner edge of the bottom of.

the tray being shifted to the position shown in Figure 3. Due to the ogee formation of the spring arm, the inner end of the tray may be raised slightly when it is moved into position to prevent injury to the surface of said sill.

The tray may be made of sheet metal, aluminum, plastic or any other suitable materials. The upper free edges of the side walls 23 and 24 may be formed into a bead when the shelf is manufactured from a plastic, otherwise the edges are rolled as a protection to the hands of the operator and may have a reinforcement of wire.

The tray may have any suitable length and width. When the tray is sufficiently long to extend approximately the length of the window sill l3, two attaching arms 35 or 50 are employed for engagement with the pair of hand lifts 12 secured normally to the window frame.

The bottom of the tray is sufficiently rigid to support the weight of the plants. Furthermore, the corrugations 22 not only aid in stiffening the bottom but provide a means for watering the plants through the perforated bottom of the pots when a predetermined level of water is main- I tained in the pan-like tray.

In order that the tray may be supported against displacement, in the event that the window is opened, opposed ends of the tray are provided with a sliding catch 55 having a knifelike edge adapted to engage between the moulding 56 and the sash ID, as shown in Figure 4.

I claim:
