' 6 Claims. (Cl. 257-36) for example, so that it can be folded under the M In the drawing I have illustrated my preferred form of strucunfolding and of easy securing the condenser assembly in bent shapeor straightened out as in use.
I refer to the appended claims for a. statement of the invention inherent in the structure illustrated and described. In the drawing:
tion of the condenser showing how I may provide 40 a bendable joint therein.
Fig-.4 is a section taken along line 44 of Fig. 3. Fig. 5 "is a-fragmentary side elevation of the condenser when .in its bent position.
Fig. .6 is a fragmentary side elevation of the 45 upper left hand side member. I
' Fig. 7 is a fragmentary side elevation of the lower left hand side inember, and Fig.8 is a plan view of the tubing support used atthe bendable portion of my condenser.
I have shown a refrigerator cabinet I, and at, the rear thereof a condenser unit marked 2. There are pipes and lconnecting up the con- ""fdensei"-with the rest of the refrigeration unit.
The pipe 3 extends to the compressor 5 from the .85 top of the condenser, and the pipe 4 extends up from the bottom of the condenser to the top where it passes inwardly near the pip 3 and is connected to the evaporator 6 of the unit.
The mode of shipping a refrigerator is to ship the cabinet in one package and ship the refrigera- 5 tion unit, fullycharged and ready to operate in another package; The cabinet, as per present practice has an upper compartment in it, which is open to the back of the refrlgeratorpand the The problem for which my invention is a soIu- 5 tion, is how to arrange the condenser of the new nected up with the other parts of the unit.
The preferred mode of accomplishing this isthe condenser are separate from those of the lower half.
The outside strips are thicker than the fins and preferably made of angle iron. They too have holes in them for passage of the tubing, and I V are assembled with the tubing when the fins are added.,' I-provide in the present embodiment two upper outside stripss and two lower outside strips Ill. Also, preferably, I provide fora diifer- 40 ent tubing-arrangement at the point where the upper and lowervoutside strips are joined, for a purpose which will be noted. Here I interrupt the hairpin like arrangement and instead provide 7 for two straight tubing sections I I, I I, heavier union fittings H at their ends, and an S-shaped piece of copper tubing l3, which is welded into each union. I V
The support for the ends of the straight portion of tubing section H, are two metal plates 5 14. Each plate has a'hole fitted with a grommet I! for sustaining the tube section l3, and'an elongated slot It, for a' purpose to be noted. The arrangement at the right hand side is the same as the arrangement at .the left hand side but merely set upside .down, so that no rights and lefts are required.
on the other side, the strip l0 being reversed in direction.
I will accordingly describe the left hand arrangement since the'right hand arrangement is the same thing reversed.
The lower end of the left hand strip 9|.is formed with a slot i1, terminating in a round portion l8, into which the grommet of the tube supporting piece is thrust. It also has a slot I9, open' to the back of the condenser arrangement. The upper end of the left hand lower piece ID has a slot 20, facing upwardly and terminating in a rounded portion 2|. for reception of the grommet on the supporting piece. It has also a closed slot 22, which is spaced from the portion 2|, butwhich is an extension in the same direction of the slot 20,
There is a bolt 23 which passes through the supporting piece 14, and'through the slots in the outside strips 9 and I0. When the two strips are in line this bolt passes through the elongated slot I6 in'the piece l4, and slots l1 and 22 in the pieces 9 and I0. Inthis position shown in Fig. 3, the condenser is extended in" a single plane, and held fast in By grasping the two sections of the condenser and bending the lower half to a right angle with the upper half, which is permitted by the bending of the S shaped pipe, and the bending of the connector pipe 4, the bolt and supporting piece and outside "strips can -be brought to a fixed right angle relation as shown in Figs .5.
In this relation the bolt being first loosened, and the condenser bent to a right angle, the closed slot 22 of the lower outside strip. Hi, can be brought in line with the slot IS, in the upper strip 9. The bolt can thenbe moved along the slot in the supporting piece l4, until it passes I through'both the slots 22 and I9, and can then be fastened. In doing so the two strips Sand ill pivot on the grommet. When fastened the bolt holds the outside strips at a right angle.
When the condenser is so bent, it can be packed in such away as to lie under the compressor -unit, and Jshus require a packaging case very little larger. than if the condenser were not packed. If the condenser had to be packed in a single extended relation, it would require a packing 'case as long 'as the condenser, and considerable in theway of supports for the rer'nain-.
der of the unit. I I 4 When received at the point for. assembly, the
operator will. loosen the twobolts, slip them out of engaging position with the sidepieces, bend. thecondenser back into straight relation,
and then slide the bolts to position to lock the side pieces in the extended relation.
The only difference as to the right hand side of the arrangement is that the'tube supporting.
piece is reversed in position, and the bolt slides down instead of up in making theflnal straight line adjustment.
Other. ways of arranging for a simple joint, lockable in two positions will suggest themselves,
and I do not limit my invention to the par-1 ticular form shown. One. essential item is that the condenser when shipped is in fully connected position with the rest of the refrigeration unit,
which unit iis charged withrei'rigerant, There-- fore it is undesirable to' have any'unions or revo- I The upper strip 9 on I the one side is the same as the lower strip to this plane by the bolt.
" said side support for the two sections ,luble joints in the tubing, since all 'jointsshould be tightly sealed.
The precise construction of the two condenser sections is not a necessary item of my invention,
the important feature being that thre are two sections connected by a bendable tube section.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
l. A condenser for refrigeration units formed of a plurality of sections, each comprising tubular elements, a; bendable tubular element between the sections, and side members for the sections, said side members having connections having locking means for holding theside members in extended and angular relation with each other, as desired.
2. In combination, a sectional condenser formed of tubular elements,
with the side supports at an angle with relation to each other.
3. In combination, a sectional condenser formed of tubular elements, having a bendable tubular element between sections, and side supports for said tubular elements for each section,
them pivoting about the said bendable tubular element, and securable in positions with the side supports in extended relation,
and in positions with the side supports at an angle with relation to each other, the said connections comprising slotted plates through which the bendable tubular element passes, bolts for said slots, a slotted end on one of the side supports'of each pair, an internal slot on the other side support of each pair, and a slot at an angle to the slotted end of the first noted supports, whereby the bolts passing through the slotted plates, may pass selectively either through the internal slot and slotted end, or between the internal slot and the slot at an angle hereto.

A condenser forattachment to and shipment with a. refrigeration unit assembly in fully charged condition, comprising a pair of like sections forming tubular passages, a bendable tube connecting the sections, and framing for the sections formed of side pieces, and links for joining them together in aplurality oilocked positions.
6. vA condenser for attachment to and shipment with a refrigeration unit assembly in fully charged condition, comprising a pair of like seclions forming tubular passages, a bendable tube connecting the sections, and framing for the sections formed of side pieces, and links for joining them together in a plurality of locked positions, said framing and links being formed alike the two sides thereof.
