This increased sealing effect is provided by the increased area afforded by the inclined sur" face '6. In other Words the construction provides .i
for normal free movement of the person when subjected to ordinary atmospheric pressure existing at low altitudes. Whenfthe aviator ascends to such altitudes as 35 or 40 thousand feet, consid- K erable internal pressure must be provided to counteract the change and as these pressures are provided thesealing effect is increased, and naturally the mobility of the person vis decreased, because he is .incased in. a pressure. 'garment which naturally tends tomaintain amore rigid position and condition upon this increase of internal pressure. t
The 'first step necessary in the formationA of a preformed glove is to provide a suitable co1- lapsilole core or formlwhich can b e removed, and -1 this corev is made by making a moulage mold of the object, i. e., the hand. n Asvwell knownin the art, a moulage consists of a material conforming to the hand and may be stripped off without deleterious effects to the skin or mold. This makes a negative mold indicated bythe numerall and one luponvvhich the lpositive mold may be made by pouring in postmoulage toz form a positive mold. After the positive moulage mold is made it is dipped in a latexA bath and coagulated A and dried to begin the formation of al mold bag indicated by the numeral 8, Figure 2. The latex preferably contains Ethyl-Zymate as an accelerator. After the mold is dried it is then covered with 'a' silk lreinforcing fabric.
v After this operation a' covering of silk fabric is applied' to the glove mold which has been sprayed with latex and a' wetting agent and Ethyl-Zyrnate. After this operation the mold bag is again dipped in latex and a coagulant solution and dried'as The bag' thus formed by the repeatedbefore. applications of material as -above statedI is now cured by heat'to melt the postmoulage so that it may be removed from the mold bag.
The mold bag thus formed is now ready for.`
,attachment to a detachable base indicated by the. lnumeral `l! and containing a valve for the infiation of the bag, which may be connected to any convenient source of air pressure; not shown'.
Having thus formed thebag, it may then be` repeatedly dipped in latexand coagulant to vide a heavier structure, if desired.
After the formation of the mold bag 8, as above described, it is now in'ated tothe desired size and treated with av non-adhesive substance,v`
for subsequent operation. This application .of the non-adhesive substance prevents the rst application of latex from -adhering to the` mold bag and therebypermits the ready removal of the glove when subsequently completed; It will be,
understood that the degree of inflation will change somewhat the size of theiingers in relation to the palm portion to provide an inflatable core upon which the glove may now be formed.
A suitable collapsible form having nowfbeen provided, the next step is to make a glove ofthe .suitable rigid implement (not shown) so as to "firmly and uniformly adhere and unite the silk fabric to the latex. The stake form is then removed from the core and the core is then again inflated to the desired previous pressure.
-After this operation the glove is reinforced by the `addition of the preformed curve metal palm plate v3 is applied to the latex body. After the palm plate is applied it is covered by a heavysilk reinforcing material Ilv which completely covers and extends beyond the palm plate 3 in all directions as shown in Figure 4., It being understood that the palm plate is-initially secured to the latex material by a heavy latexcement. After the palm plate and the reinforcing material is applied to the glove material, the glove portion is then vnnally dippedin latex tovprovide the4 desired cov,- ering. This final dipping operation may bey repeatedlyapplied until the desired thicknessof the glove iscbtained and all. theparts formed into a smooth and finished article for the yplurpose intended. Y
- After the final dipping operation the mold .is deflated and the glove stripped from the mold, and thus inherentlymaintains its deslred'preformed configuration. y
In the form shown in Figure l it will .benoted that the Apalm plate includes a palm projection portion I2 and a curved portion. .|43 extending between the thumb and rstfnger. These curved portions provide a rigid palm section which enables the hand to maintain a rm natural grasp on an object, when the glove is subjected to relatively high internal pressure, with a minimum of muscular. effort. f Y
Furthermore, the curvature-of the finger portions in relation to the palm structure causes the thumb and fingers to in effect contract relative tothe palm. y l
The feature of the proposed glove is that under normal atmospheric pressure conditions theiiexibility of the materials enables the glove tobe used in the regular way, but-whensubjected to pressure it resumes a preformed condition for vwhich it` is desired.
Having thus described a glove constructed. in accordance with .the present invention, :it is obvious that various changes rmay be made therein without departing from the scope of the invention as set forth infthe claim.
As a new article of manufacture, an inflatable utility glove adapted to withstand internal pressure and having finger and thumb members. the thumb member preformed` in fixed curved relation toward the iingermembers, means reinforcing the glove so that the. ngers shall. tend to contract relative to the thumb and increasethe grasping effect of the glove when internal pressure is appliedfto theglove, and a seal connection member for attaching the gloveto va pressure garment sleeve for inflating the glove..
