y This invention relates to an improvement in door closures. y y

The object of the invention is to provide `a double-seal for close 4fitting doors and I other similar forms of closures,Y as for 1nstance jas used on refrigerators, ice boxes. refrigerator cars and, inA fact, wherever a closure is desiredyto closely confine air. lgas or a liquid, or to provide a good insulator for a cooling s ce. Y s

A further' object of the invention is to allow for cleaning both opposite sides of plates of glass which are mounted in refrigerator or other similar doors wnere several u thicknesses of glass are used. It has been customary in the art to provide display refrigerator doors with several thicknesses of glass in an etort to secure a better insulating Y door` and it has `not been possible heretofore 9 to clean the inside surfaces of the` glass by reason of the .construction of the door, but

this is accomplished by the use of this inven-` tion.

The door is `formed oftwo or more sections u which are preferably independent ot each otherA and kept in spaced apart' relation by` means of suitable resilient means as for instance coil springs sleeved over bolts which extend between the two sections of the door n and hold the sections apartv while the bolts limit the outward movement of the two sections relative to eachother. Each of the sections carries a glass and by reason ot the independence of the two sections. it is possible to clean both sides of the glass in each section. The springs between the two sections likewise allow for a double-seal between the door and the door-frame. one of the seals being carried by the main pivoted door section while the other is `resiliently carried by the movable section. In this way. a tight fit and closely confining door is obtained.

In the accompanying drawings: Fig. 1 is a perspective view of the door; and

Fig. 2 is a horizontal sectional view therethrough.

The door may be used as a closure for refrigerators. refrigerator cars or. in fact, wherever it is desired to provide a tight tit between the door and the frame-work or articles to which it is applied. As shown in Fig. 2, the frame or wall for `supporting the door is designated lgenerally by the numeral 65 1, and has the main door section 2 hinged i shown). y

thereto as at 3. The main section `2 carries 'i crates with the plates 4fY for the purpose of `insulatingthe door. 'The springs y ...s 6 are sleeved upon bolts 9 which extend between f. the sections 2 and 5 and serve to `connect `the sections ot the doortogether andcontine the outward movement of thesection `relative to the section 2.

A cushion seall() which may be formed of felt. rubber or any 'suitable material. is secured about the edge ot the main' section 2 of the door. as shown in'Fig.. L for engaging the supporting frametfor the doororsirnilar closure to provide` a tight seal therebetween whenever the door is closed by any `suitable form of locking handle (not A corresponding cushion seal 11 tion 5. as shown in Fig. 1. to engage a ledge 12 formed in the door-frame. The door is vshown as closed, in Fig. 2, and when in such closed position it is doubly sealed as at 10 and 11. The spiral springs 6 exert pressure on the seal 11 and hold it tightly against the ledge 12 and together with theseal at 10 it is obvious that a very tight tit is obtained between the door and itssupporting frame.

Asshown in the drawings. the sections 2 and 5 are entirely separate trom each other and are held in spaced apart relation by means of the springs 6. The frames ot the sections are not joined and in that way it is possible to gain access to both sides of the glasses 4 and 8 in order to clean these glasses and to give the door a better appearance, especially when used for refrigerator display cases.

As stated above, the double seal is provided at 10 and 11. the seal at 1() being closed by means of the hinges and locking lever or handle. which forces the main door section 2 against its supporting frame, and the seal at 11 is held tightly against the ledge 12 in the frame by the expanding Springs 6, and in this way the door is kept tightly sealed to act as an insulator especially where used on refrigerators or similar articles in order to keep in the cold air and keep ont the Warm air. The invention may likewise be similarly applied to any suitable form oit closure VWhenever it is desired to closely confine air,

gas or liquid.

I claim:-

1. A closure of the character described including independent sections having the frames thereof entirely disconnected from each other, means for limiting the outward movement ot' each section relative to the other, and resilient means interposed between said sections normally tending to hold the sect-ions in Vspaced apart relation.

Q. A closure of the character described including independent sections formed of frames disconnected from and independent of each other, each of said frames carrying a glass, bolts extending between the frames for limitingr the ontivard movement thereof relative to each otherand resilient means sleeved over the boltsand interposed between the frames of the sections normally tending to hold said sections in spaced apart relation.

3. A closure of the character described including independent sections. resilient means normally tending toliold said sections in spaced apart relation, and a cushion seal carried by each of the sections.

4. A closnreof the character described including independent sections formed of frames disconnected from and independent of each other, each of said frames carrying a. glass, bolts extending between the trames for limiting the outward movement thereof vinding independent sections having thel l'raiiies thereof entirely disconnected yfrom each otherbolts extending between the sections for limiting the outward movement thereof relative to each other,said bolts being the only connection between the sections, and resilient means sleeved over the bolts and interposed between the frames normally tending to hold the sections in spaced apart relation.

6. A closure of the character described inf clnding independent sections having the frames thereof entirely disconnected from each other forming circniiiierential openin s for rainingr access to the space het'iveenV t eAL sections, bolts extending between the frames of the sections for limiting the outward movement thereof relative to each other, said bolts beingr the only connection between the sections, resilient means sleeved over they," bolts and interposed between the frames normally ytending to hold theueections in spaced apart relation, and plates of glass mounted in the sections.

In testimony whereof I aiiix my signature,

GEORGE r. BANTA.
