4 VACUUM BOTTLE. APPLICA TION FILED MAY 3, I920- Patented Sep t. 14,1920.
A HNEVS UNITED STATES i I CLARK, OF NEW BRITAIN, CONNECTICUT, A CORPORATION OF CONNECTICUT.
VACUUM-BOTTLE;
' To all whom it may concern:
' heretofore in use.
Be it known that I, HLERBERrM. SMITH, a citizen of the United States, residing at Farmington, county of Hartford, State'of Connecticut, have invented a certain new and useful Improvement in Vacuum-Bottles, of which the following is a full, clear, and exact description.
My invention relates to vacuum bottles and has for its object to provide new and improved separators for the inner and outer members of the container to prevent the inside member from breaking under vibration'or shock. It further has for its object to produce a separator which will be of less heat conductivity for the same amount of contact surface than separators It further has for its object to provide a substantial separator which has small areas in contact with both the outer and inner walls, so as not to produce spots unsightly in appearance. This is of importance since where the separators produce unsightly spots it leads users to think that they are caused by dirt and try to wash them off, such eiforts sometimes leading to the breaking of the container. It further has for its object to provide a separator in which the points of contact are elongated and parallel to the axis of the bottle. It further has for its object to reduce the occluded gases to a minimum. It further has for its object to provide a separator having mica contact pieces havsmall contacting surfaces.
The following is a description of an embodiment of my invention, reference being had to the accompanying drawings in which,
Figure 1 shows a section of a vacuum bottle embodying my invention;
Fig.2 is a section of the total circumference on the line 2-2, Fig. 1;
Fig. 3 is a separate view of one of the separators;
Fig. 4 is a view of the supporting memi ber of the separator; and,
Fig. 5 is a view of a blank to be inserted in the support of Fig. & to form one of my separators.
Referring more particularly to the draw ings, 1 is'the outer member of the container in this case glass, and 2 the inner member thereof. 3 are V shaped pieces of non-conducting material, preferably mica, stamped into the shape shows at in Fi 5 and.

. bent attheir centers so asto form two legs. 4 1s a support for these bent mica'p'ieces, preferably of metal and v formed with two frames 5 or equivalent means tying together the legs of the mica and holding themin spaced relation and preventing the body portions of said legs from spreading.

Theseportions are connected by a strip 6 preferably narrow, as shown, to reduce the I amount of' metal and the weight. The mica pieces are provided with shoulders 7 and tongues 8, and when bent the tongues are lnserted through the frames 5-5 so that the tongues protrude and" the shoulders engage the sides thereof. The mica pieces are thus held in place. The separators thus formed are forced into the space between the two members. Preferably I use three pairs as shown in Fig- 1. They are held in place by the frictional engagement of the ends and apices with the walls of the inner and outer members. The mica is elastic so as to have a yielding spring action, particularly at the ends engaging the inner member. The separators beingmade from flat strips their legs are flat and the planes of thelegs are parallel to the axis I I of the inner and outer members, This action aids in maintaining the frictional engagement. The portions of the mica which contact are elongated and also parallel to the axis of the bottle, producing little dis-' figuration even when the bottles have their opposing surfaces silvered. The regular geometrical form of the spots produced shows that they are structural and the spots being less conspicuous than spots heretofore formed are less likely to result in attempts at removal. The small amount of metal used and the use of mica result in the substantial absence of occluded gases and in a reduction of the heat conductivity of the separator, and. increase the thermal I thereof or the scope of the appended claims. 7

2; In a separator for vacuum bottles, the combination of a non-metallic elastic strip of low heat conductivity having two projecting legs, means connecting said legs at points removed from their extremities and holding them in spaced relation, said strip eing V-shaped.
3. In a separator for vacuum bottles, the combination of two non-metallic strips of low heat conductivity each having two procombination of a V-shaped sheet mica poron, and means tying together the legs of the V and holding them in spaced relation reventing the body portions of said legs .rom spreading.
In a separator for vacuum bottles, the

6. In a vacuum bottle, the combination of a container having an outer member and an inner member and a plurality of separators interposed between said members, said separators each being composed of a bent flat strip and having flat projecting legs arranged atan angle to one another, means for tying together said legsand holding. them in spaced relation and preventing the body portions of said legs from spreading, the
