T 0 all whom it may concern.

Be it known that I, EUGEN URBAHN, a citizen of the German Republic,- and a resi dent of Berlin, Germany, have invented cer tain new and useful Improvements in Means for Supporting Vacuum-Jacketed 'Bottles or Other Receptacles Within InclosingCasings Therefor, of which the following'is a specification. 1

This invention relates to means for supporting vacuum-jacketed bottles or other receptacles within inclosing casings there for, and particularly to a device for resiliently supporting the bottle or receptacle within the said casing and comprising a number of vertical spring-members or arms laterally engaging the outer wall of the bot tle or receptacle and a resilient horizontally extending member engaging the lowermost or bottom point of the said bottle or receptacle, all of the said members being united to form an exchangeable structure of interdependent resiliency. I

It is known that vacuum-jacketed bottles are very fragile and for this reason are usually enclosed in a metallic casing. The provision ofthe protecting casing,however, does not afford suflicient protectionso that it has been found advisable to further protect the fragile glass body by means of resilient supports preferably provided in the bottom part of the casing so as to contact with both the casing and the bottle. The yielding supports hitherto suggested comprise coiled steel wires, flat steel springs and the, like, but the shape, construction and arrangement of the yielding members heretoforeeniployed are such that a durable or lasting protection is not obtained thereby mainly, since-the yielding eliicienc) of said members soon decreases and the bottle then will be liable to fracture in case of any shock hitting the bottom of the bottle. v i

The object of this invention is to provide an improved support with a view to remedy this defect andwhichwill form, as hereinbefore stated, a yielding bearing adapted to support the bottom part of the bottle or receptacle both laterally and from 'below, the construction and arrangement. of the parts being such that when a pressure or force is exerted upon or hits the encased bottle so as to be intercepted and counteracted'by the resilient support, the laterally jacketed bottle with the metallic casing engaging orcontacting fingers or arms will tend, owing to the fact that all ofthe' parts form a unit of interdependent resiliency, to converge with relation" to each other or to a common central point lying withinthe longitudinal axis of the bottle, sothat even if the resiliency or elasticity thereof diminishes in the course ,of-time, stillga'reliable yielding support will be ensured' for any length of time. I i i In the, accompanying drawing forming part of this specification an embodiment of the invention is shown'by way of example, it being understood that changes in the form proportion, size and minor details may be made within the scope of the claims witl1- out departing from the spirit or sacrificing any of the advantages of the invention. In

the drawing Figure 1 is anielevation of a broken away at the lower end thereof and Figure 2 is a perspective view showing the resilient support removed from the casing.

1 is the vglass bottle of customary shape and. '2, 3 designate the bipartite metallic casing which is likewise of conventional construction. The bottom part 3 of the casing has a flat bottom 1 and is screwed into the main body 2 of the casing owing to the corrugated shape of thecy-lindrioal side walls I v of the two parts 2 and 3. v

The resilient support'5 separately shown in Figure 2 may beins'erted into the bot-. tom part 3 prior to the attachment of the latter to the main part of the casing, as will be clearly understood from thedrawm str ips, three strips 7, 8 and9 of the particular shape shown in Figure-2 being employed to constitute thesupport, although in some cases-it may'be advisable or-desirable to employ more thanythree strips. The strips are assembledand connected together' by means of'a single rivet '6 so as to form a unit in the shape ofwhatmay be called a tripod with the three feet 13 formed by a bend vertically elongated to at the same time form threeupstanding resilient arms 10, 11 and l2, respectively, adapted tolatera-llv engage or contact with the outer wall of the glass bottle 1.1"

p The distance of 'the free ends of the arms 10, 11 and 12 from each other or the radial distance thereof from the-longitudinal axis of the glass bottle 1 properly selected to The support 5 is made ofwfiat steel cause the arms, on assemblingthe parts, to yieldingly contact with theonter wall of the glass bottle without the necessity of overcoming any undue resistance opposed by the latter.

One of the three strips, in the embodiment shown the strip 7, is extended beyond the rivetting point and the elongated end 15 is bent and turned back to form a resilient seat for the lowermost bottom point of the bottle. If a pressure is exerted on theturned-over end 15' of the strip 7 the end 15 will yield in the manner of a spring, but at the same time the parts of the three strips in the vicinity of the rivet 6 will likewise yield and move downwards and act as a spring or cushion in case that the three feet '13 are supported, say by the bottom 1 ofthe part 30f the casing. By thus depressing the horizontal parts of the three strips the free ends ofthe upstanding arms 10, 11 and 12 Will move radially inwards and exert a gripping action on any body, say the bottle 1, inserted thereb'etween, no matter 'whetl'ier they have been in a more or less slight touch with the latter previous to the depression of the horizontal parts of the strips, or not.

It will be seen that the bottle 1 duly supported in this manner, as shown in Figure 1, is protected from fracture in a by far better way than through the usual springs. Any shock or pressure accidentl-y imparted to the top or bottom ofthe vacuumjacketed bottle will be yieldingly intercepted and counteracted by the resilient support 5, whereof the springy seat 15 acts like a buffer spring at the same time transmitting the received shock partly to the three lateral arms 10, 11 and 12 so that the efiect of the shock will be distributed among and absorbed by the four yielding mem here 15, 10, 11 and 12 and no point of the glass bottle will be hit hard enough to undergo fracture through the action of the acci dental shock,

The three arms keep the bottle alwaysii'i centered position and obviously are adapted to individually absorb lateral shocks. The parts can be readily assembled by siliding the three arms of the support 5 onto and over the bottom of the glass bottle 1, insertng .the thus combined two parts into the main body 2 of the casing and attaching the bottom part3 of the casing to-the main body by screwing the former into the latter, or dismounted by proceeding in the reverse order. It will be seen that the lowermost portion of the bottom 'part- 3 of the metallic casing is circumferentially extended to form a circular groove 14. for the three feet 18 to engage therein either during or prior to the assemblage of the parts shown in Figure 1.

Although it has been found in practice that a (support 5 comprising three resilient strips answers well the object aimed at, it may be deemed convenient in some cases to provide more than three strips which would still come within the scope of the invention. For though I have described with great par-- ticularity of detail a specific embodiment of the invention, yet, as above intimated, such embodiment is only an example and it is not to be understood therefrom that the invention is limited. to the particular embodiment disclosed.

l i hat I claim is:

2. A device of the type described for resiliently supporting a vacuum-jacketed bottle or receptacle within an inclosing casing, comprising a number of radially arranged resilient strips firmly interconnected at their meeting point, feet formed in said strips by bending, upstanding resilient arms projecting from said feet, and a yielding support (15) formed by the turned-over projecting inner end of one of the three strips and affording a seat for the bottom of the bottle or receptacle, substantially as described.

3. A device of the type described for resiliently supporting a vacuum-jacketed bottle or receptacle within an inclosing casing, con'iprising three radially arranged resilient strips Firmly interconnected at their meeting; point a foot formed in each of the said strips, an upstanding resilient arm project ing from each foot, and a yielding support formed by the turned-over projecting inner end of one of the said three strips and fording a for the bottom of the bot tleor receptacle, substantially 2S and for the pur pose set forth.
