FRIGIDAIRE CORPORATION, OF DAYTON, OHIO, A CORPORATION OF DELAWARE I BEFRIGERATING APPARATUS vApplication fll ed. September 2, 126.- Serial 1T0. 188,197.

This"invention relates torefrigerating apparatus of the compressor type, it more particularly relating to the condenser for the refrigerant and the cooling means for thesame. I

One of .the objects of the invention is to improve the construction of the condenser coil to provide a coil which will have an increased capacity over other coilsoccupying the same space.

- A further object of theinvention is to provide a condensing coil so constructed and arranged in connection with a cooling fan to provide for an effective cooling 'of thecoils.

Other objects will appear from the accompanying description and claims.

Referring to the drawings:

Fig. 1 is a plan view of an apparatus embodymg my improvements.

- Fig. 2 is a side elevation of the same. Q

Fig. 3 is a vertical section through a portion of the condensing coil.

Referring to the drawings, 1 represents a cfim ressor, 2 a pulley on the end of the s a The improved condenser is supported on the base 6 between the motor and compressor and consists of a coiled pipe the turns 7 ofwhich are projected inwardl on four sides preferably on a curve as in icated at -7 so that each coil turn will present somewhat of a star shape. The condenser ,coil

is supported in the following manner:

Four equally spaced metallic straps 8 are provided, the lower ends of which are bent at right angles to form feet 9 secured to the base 6, while the upper ends thereof are likewise. bent at right angles as indicated at 10, and extend to the center ofthe coil where they are united-by a belt or screw 11. Referring more particularly to-Fig. 3,

' there is. also associated with each strap --8 a clamping: bar 12 secured tothe s'trap screws-13 and haying rounded recesses 14 thereof, 3 an electric motor, 4 a pulley on the end of the shaft of the motor, and 5 a belt running from the pulley 4 to the to receive the bent portions 7 .of the coil turns so that the coil may be firmly clamped to the straps.

A cooling fan 15 has its shaft mounted in a bearing at the upper end of the standard 16, the lower end of which is adjustably mounted on a dovetail groove formed in a bracket 17 on the base 6 andadjustably held thereon by a screw 18 which extends through a slotted opening 19 in thestandard so that the standard may be adjusted 'as to height. The shaft 20 of the. fan has a pulley 21 over which passes the belt- 5, the adjustment described permittin the pulley to be adjusted in proper" relatlonto the belt.

By having the coil of the condenser formed as described, it will be seen that a greater capacity for the refrigerant is secured over a coil of usual form occupying the same space. Further, by so formin the coils it will be seen that all sides 0 each coil will be placed in the path of the air current from the fan so as to secure a greater cooling effect.

' Having thus described 7' my invention, I

claim 1. In refrigerating apparatus a condenser including a(plurality of substantially square loops space apart verticall and arranged in a stack, a plurality of said loops havlng adjacent sides bent inwardly to present convex surfaces to he longitudinal axis of the condenser, an means for supporting the loops in said-irertically spaced relation.

2. In refrigerating a paratus, a condenser including a lurality of substantially square loops spaced apart-verticall and arranged in a stack, a plurality of said loops having all four sides curved inwardl to present convex surfaces to the vertica axis of the condenser and means for supporting the loops in said spaced relation substantially as described.

3. In refrigerating apparatus, an air cooIed condenser including a single continand arran ed in a stac each loop having 'uous conduit bent to form a. plurality .of substantially square s, vertically spaced convex surfaces to the vertical axis of the oondenser, means for supporting the loops 1n sald vertical spaced relation and means for forcing air over the said loops.

In testimony whereof I have hereunto set my hand this th day of August, 1926.
