13 Claims.

Our invention relates to a new construction, particularly for refrigerator closures where it is designed to provide a door to close the opening of a refrigerator and wherein no wood or noni metallic parts are exposedabout the door edge with the exception of the door gasket.

A feature of the invention resides in providing a closure for a refrigerator which permits the inner and outer faces of the closure to be made l@ of metal or other suitable material which may be enameled with a vitreous enamel, or otherwise coated, to protect or decorate the surface of the same and wherein even the edges of the door are of metal and yet where these parts are connected l5 together in such a manner as to prevent conductivity of heat and cold from one face to the other face of the closure.

A further feature of the invention is to provide a closure wherein a gasket or gasket members are 2@ interposed between the connecting parts or coverings of the door which act as breaker means to prevent conductivity of heat or cold and also actv as gaskets to form a sealing medium about the door and opening so as to seal the refrigerator when the door is closed. We employ a double beaded gasket which also serves the function of providing an inner bead clamped within the parts of the door in such a manner that the gasket will not pull out and providing a construction where the means for clamping the parts of the door together and also for holding the gasket in place are concealed within the body of the door to make a neat appearing edge about the entire door.

Another feature of the invention resides in a door structure made with its entire outer covering of metal or similar material which may be covered with enamel or any suitable material to protect or decorate the surface of the same, and wherein certain structure is provided for holding the parts of the door together and also to brace the door or closure to make a strong, solid practical closure for a refrigerator, where the same must be subjected to heavy duty.

Other features and details of the invention will be more fully and clearly set forth in the specification and claims.

Figure 14 is a perspective view, a portion of which is broken away, of the brace structure used in the construction of our door illustrated in Figure 10.

In the drawings for convenience we have illustrated a portion of a refrigerator A in section in Figure 1, and also the door or closure B so as to show the relation between the parts of ther same. The refrigerator construction here employed is where the lining l0 of the refrigerator is made of metal or other suitable material which may be enameled with a vitreous enamel or otherwise protected, as well as the outer surface 11, and by means of a suitable breaker strip 12 about the door opening and which construction lis illustrated in another co-pendng application Serial No. 419,522, filed January 9, 1930, the entire refrigerator A may be made with a metal structure and yet the objectionable conducting of heat or cold about the refrigerator door opening is overcome.

It is the purpose of this invention to set forth the construction of the closure B in relation to the refrigerator A and wherein the outer face 13 and inner face 14 of the closure B -are made of metal or other suitable similar material, and to provide a breaker structure such as 15 between 105 the outer face 13 and the inner face 14 to prevent the conductivity of heat or cold from one to the other.

The construction of our closure B may be made in several different forms and in that illustrated in Figure 2 the .outer face i3 is ccnnectedto the inner face i4 by the breaker strip 15. The breaker strip l5 is also made of metal and the outer surfaces of the portions 13, 14 and 15, may be enameled or covered with any suitable decorative or protective material as may be desired. It is desirabie to enamel these parts so that they can be readily washed and cleansed at any time, leaving a smooth polished hard glass-like surface which is not ordinarily affected by moisture. In this manner we provide a door structure where 'no wooden or other non-metallicfportions are exposed between the outer face 13 and the inner face 14 oil the door' closure. The only non-metallic parts are the gaskets such as C which are clamped between the portions 13 and 14 and the connecting breaker strip 15.

It is a feature of our invention to use a particularly desirable gasket such as C and C' wherein an outer bead 16 is employed, and an inner bead 17, which are c onnected together by the web 18. In the form of the gasket C' the web 18 is narrower than in the form C. This will be clearly disclosed in Figures 6 and 7.

In Figure 2 we have illustrated the breaker strip 15 connected by the bolts 20 to the inner covering 14 of the door B and these bolts 20 are inclosed within the door structure in such a manner as to conceal the same. The other 'edge of the strip 15 is connected to the outer face 13 of the door B by the bolts 21. The heads of these bolts show on the inner edge of the strip 15. It may be noted that the gasket strips C are clamped with the outer bead 16 exposed while the inner bead 17 is anchored within the door structure and is concealed therein, and thus the gaskets C are heldagainst easily being misplaced or pulled out and yet provided with a large bead 16 which forms the gasket to engage against the surface about -the door opening of the refrigerator A to seal the refrigerator when the door B is closed.

In Figure 3 we have illustrated the breaker strip 15 connected by the bolts 22 and 23, the heads of which are exposed in the same manner as the head of the bolts 21. The functions of this structure are-identical with -that of Figure 2 in the breaking of the contact between the outer face .13 and the inner face 14, and thus by means of insulating C we provide a double function to break the conductivity between the portions 13 and 14 and also to provide a sealing means about the door when it is closed.

In Figure 4 we have illustrated the breaker strip 12 of the refrigerator A in enlarged formation to conform'with the door B and to show the manner in which the gasket C contacts with the breaker strip 12 which forms a. shoulder for engaging the inner gasket strip C of the door B. In this construction of the door B the inner gasket C is held by the bolts 20 to connectl the inner edge of the breaker strip 15 the same as illustrated in Figure 2. The outer portion of the breaker strip 15 illustrated in Figure 4 is connected to the inner frame brace D by the bolts 25. This frame D is formed with a flange 26 which pinches under the inturned edge 27 of the outer door covering 13 and pinches the gasket between this inturned edge 27 and the edge 28 of the breaker strip 15. A

When the door B is put together as illustrated in Figure 4, the frame D is embedded in between the outer face 13 and the inner face 14 and a strip of insulating material 29I is laid between the frame and thev outer face 13 and the screws 30 ofthe door hinge 31 engage with the frame D together.

in a manner to hold-the parte connected te# gather."v

In each of the doors E any 'suitable insulating material is held between the door coverings 13 and 14. En Figure 3 we have illustrated a Vmore simple form of our door E where a frame such as D similar to the frame D may be ein played to hold the outer face i3 connected with the inner face 14. In this construction we do not use the breaker strip 15 but use the bolts 32 which operate similar to the bolts 25 and whereinthe flange 26 engages under the inturned edge 27 of the door facing 13 to hold the parts In this structure of Figure 8 of the door, we use the closely coupled gasket C. The other side of the door is held by the bolts or screws, such as 30.

Our door B may be made also in the structure illustrated in Figure 9 without the breaker strip 15 and in this construction suitable bolts 33 hold the gasket insulating strip C in place with the ilange 34 of the inner face 14 clamped against the inturned ange 27 of the outer face 13. When our door B is made as illustrated in Figure 10 the outer face 13 is connected by the brace members 35 which extend transversely across the inside of the face 13 laying against'the insulating material 29. This brace 35 is formed with flanges 36 which operate similar to the flange 26 to engage under the inturned edge 27 of the outer face 13 and the other side of the braces 35 are held by the bolts or screws 37 which hold the hinge 31 on to the door B. In this construction of the door, we have illustrated in Figure 11, the inner face or covering 14 fonthe door B, and in 110 Figure 13 the outer covering or face 13. These two Figures 11 and 13 will show the inner and outer faces of the door structure of Figure 10.

In this door structure of Figure 10, an intermediate breaker strip 15' is employed made of 115 the structure and nature as illustrated in Figure 12 and connected with the cooperating yparts in Figure 10. It will be noted that in this structure bolts 38 hold the inner gasket C in place to form the insulator between the inner surface 120 14 and the breaker strip 15' and this gasket is held in a little different manner than in the other door structures. The other portion oi' the breaker strip15' in this structure of door is connected by the bolts 39 to the upstanding flange 40 of 10,5 the brace 35 and an insulating strip 41 may be provided between the parts. In connecting the parts, the parts of the door B of Figure 10, the short coupled gasket C' is used between the breaker strip 15' and the inturned flange 27 of 130 the outer face 13 as illustrated.

In each of the door structures set forth and described the primary feature resides in forming a door with a metal outer covering which may be enameled, painted or decorated to protect and 13@ cover the outer surface of the metal in any suitable manner and to provide a door without any wooden connecting parts between the inner and outer faces 13 and 14, but rather with only the gasket portions C and C exposed. The gaskets C and C are made of a material to provide an outer water-proofed covering so that they can be washed and so that they will'not ordinarily be affected by moisture.

As has been described, Figures 8 and 9 disclose structures wherein but one gasket is used. If it is desired, the door structures illustrated in Figures 2, 3, 4 and 10, may also be formed in this manner, one gasket, preferably the inner gasket, being eliminated entirely. The metal parts could 150 I then be bolted directly together, or any ordinary insulating strip may be inserted between the metal parts.

The gaskets C provide the function of breaking or insulating the connecting parts of the door faces 13 and 14- and also provide a sealing gasket means about the door closure. Heretofore refrigerator doors have been made with wood connecting parts between the outer face 13 and the inner face le or parte made of fibre or other non-metallic material, and such construction is undesirable. We have provided a door structure wherein all metal parts may be used for the exposed surfacesof the door, even the rabbetted edges so that a very sanitary and desirable structure is accomplished thrgughout the arrangement of the parts herein specified and described. The use of a double beaded gasket to insulate and break contacting between the parts and to act as a sealing medium. together with the preventing of the gasket from pulling out of place accomplishes certain results which have marked advantages over the practice of mainng refrigerator closures or doors heretofore.

ln accordance with the patent statutes we have v described the principles of our door closure and refrigerator closure, and while we have illustrated certain arrangement and formation of the parts, we desire to have it understood that the same is only suggestive of a means of carrying out the principles of our invention and that variations may be accomplished within the scope of the following claims without departing from the purpose and intent thereof.
