I 'sliovvnlov#Vvvay0f and not of limitation` a kpreferred embodiment l My present invention relates tov artting device for elastic articles, and more particularly to a means for applying rubber gloves and like elastic articles to other objects.

lA vpurpose. of my invention is to provide'a means talenalong line 1 -I o f Figure 3 5 showing a glove in differentpositions l.

for 4stretching, a glove or other elasticjarticles Without danger of tearing same so that the hand A further purpose of my invention is to provide a glove fitting means in which a difference inair pressurebetween the inside and outside of the glove is relied upon to expand the glove.

It is vcontemplated that my invention may `find general favor in applying any type of elastit':4 article, but it is believed that/its greatest fieldof .usefulnesswill be found' in hospitals, dispensa j :respect-. except thatthe Vparts are reversed to -Drevidexfor lMight and 1ef'hand Thereore, I ,Shall describe-onlyone suchmeans, it being understood ,that each means comprises the same ries, chemical vlaboratories and factories for' applying rubber gloves.r My invention will be found especially valuable in hospitals and clinics Where, as is Well known, the rubber gloves used" are of u the thinnest materials and very often must be applied quickly.' With my improved device itwillbe 'possible to easily and quickly apply the thinnest type of glove Without the slightest danger of tearing same as `is so often the case Where such' a glover is applied by hand. Y1 In applying a glove by'hand there is theposslbility of the glove becoming soiled and unsanitary and therefore Wherea sterilized'glove is .to be used my devicevvill be found indispensableas theglove, after being sterilized, can be placed in my device ,and then applied to the hand Without fear` of contamination.

Where my invention is installed in theoperatber, I2, I provide atWo-Wayvalve Il which .com- 1 municates with the atmosphere and also through .-ajtubeor, pipe Alvvith a suction pump or otherl Ievacuating apparatus, not shown. The evacuatng apparatus may be a vacuum pump or it may be a tankl from `which air has beenexhausted. Thevalve Il has an operatinghandle I9 which Yprojectsthrough the front Wall of the cabinet Il) and `the 4stempf the valve carriesa lugvor boss ,ing'room of a hospital the nurse, after sterili'zng the gloves, can place them inthe device Without touching more than asmall portion of the cuif;

A further advantage of my device is that with "it a user can instantly apply one or .both glovesin a simple and quick manner andconsequzently can use his `bare hands up tothe moment rthe gloves are needed and then immediately apply the gloves by merely inserting his hands into the gloves 'which have been previously placed inthe device.y

Y Whilemy invention in its broadest aspect may find manyuseful applications it is' believed, as suggested above, that its greatest Yfield of useful- I. ness Will be in applying rubber gloves.v rThereifore,.I shalll illustrate and limit my description to apparatus designed for this purpose.

VFor a better understanding of my invention yref 'o'r 'anyother objectmay be easily inserted there- .,valve.,y Y f L v In the drawing the numeral I0 designates a- I :housing or-.cabinet having `tvvo openings II inthe top thereon-.Mounted in eachof these openings {andassociated therewith I provide similar means for supporting. ,and. dilating a glove, Thesesupthereof.-

The opening of the chamber I2 is provided with aprojecting rim I3 about which the cuit-of a`glove` M ,may-,be stretched.

When the valve I'I is in the position shown in Figure 1 the interiorof the chamber I2 will be connected with the atmosphere and when the valve I'I is turned to the position shown in Figure 2 the interior of the chamber I2Y will be connected with the vac- `paratus ,and admit air to the chamber I2.

uum producing means.

At this point it should be noted that the bearing collar I5 is so designed and positioned that when the chamber I2 with the glove stretched over its rim is forced inwardly the cuil of the glove will be forced off therim I3 to facilitate a withdrawal of the glove. I y

When the cuff of the glove I4 is stretched across the open end of the chamber I2 and the air is exhausted from the chamber I2 the atmospheric pressure within the glove will cause the glove to be expanded, as illustrated in Figure 2." In order to insure thatthe glove I4 will expand uniformly 5I provide a suitable form 23 Within the chamber I2. The form 23 is'in the shape of an enlarged hand and is perforated so that it'will notl interfere with the free removal of the air about the exterior of the glove. This form 23 may be made in any suitable manner. Asillustrated the form 23 is made with a large number `of closely spaced apertures.v It can also be formed from a close meshed wire gauze.

It has been found that the fingers of the glove do not expand as readily as the body of the glove and therefore in some'cases a satisfactory form 23 can be constructed by merely providing a restraining means about the body of the glove and f leaving the fingers free to expand as they' will. 'Ihe operation of my improved device should be apparent from the above description but by way of recapitulation it may be stated that vwhen the chamber I2 isin its uppermost or normal position the user may by grasping a glove at the cuff direct it into the form 23 with the nngers and thumb of the glove in their proper positions.

After the glove hasy been thus inserted the cuff thereof may be turned down over the rim I3 of 'the chamberV lI2 so as to form an air-tight seal between the glove and the wall of the chamber r,I2 at this point. Y g

When the glove is thusv disposed in the chamber I2 the operator can then cause the glove to be expanded by simply turning the operating handle @I9 to establish a connection between thechamber I2 `and the pump or other vacuum producing apparatus. This will reduce 'the pressure within the chamber I2 and about the exterior of the glove and as a result air atrv atmospheric pressure will enter the interior of the glove and cause it to be expanded into the form 23.

After the glove vhas been thus expanded the user can easily insert his or her hand and push the chamber I2 inwardly to a point where the valve I'I will 'cuil' off the vacuum producing ap- As soon as the chamber I2 has thus been opened-to the atmosphere the glove will immediately contract upon the hand inserted therein so that the hand with the glove applied thereto can be easily withdrawn.'

vWhile I have, for the sake of clearness and in order to disclose my 'invention so that the same can be `readily understood, described and illus- 'trated al specific device and arrangement, I desire to have it'understood that this invention Visnot limited to the specific means disclosed. It is believedthat this invention is broadly new and it is desired to claim it as such so that all changes as come Within the scope of the appended claims are to be considered as part of this invention.

Having thus described my invention, what I claim and desire to secure by Letters Patent is- 1. A device for applying rubber gloves comprising a movably mounted chamber open at one end into which a glove may be disposed with the cuff of the glove sealing the open end of said chamber, a perforated form disposed in said chamber corresponding to an enlarged human hand, means for exhausting the air from said chamber to cause said glove to expand into said perforated form where the user may easily insert a hand, a, valve for permitting air to reenter said chamber, whereby the glove will be released and permitted to engage the hand placed therein, and means responsive to a movement of said movably mounted chamber for operating said valve.

2. In avglove applying device, the combination of a support, an open ended member movably mounted upon said support, said member being adapted to receive a glove with the cuH in sealing enga-gement across its open end, means forjexhausting the air from said member when a glove is disposed therein, whereby the glove will beexpanded by air entering through its cuff to permit the insertion of a hand, and means operable by movement of said open ended member for permitting air to reenter said member after the hand has been inserted into the expandedglove to permit the glove to assume its normal shape and the withdrawal of the hand with the glove properly applied thereto.

3. In a glove applying device, the combination of a support, an open ended member movably mounted upon said support, said member being adapted to receive a glove with its cuff in sealing engagement across the open end, means for exhausting the air from said member when a glove is disposed therein to expand the glove and permit the insertion of a hand, a valve for admitting air to said member after the hand has been inserted into the expanded glove, and means controlled by the hand within the glove for operating said valve, whereby the glove will assume its normal shape and permit the withdrawal of the hand with the glove properly applied thereto.

4. In apparatus for applying an elastic covering to objects, lthe combination of an open ended member into which a similarly shaped elastic covering may be placed, said member having a rim over which the open end of an elastic covering may be stretched, a support for said open ended member permitting. a limited axial movement thereof, means for temporarily withdrawing the air from said open ended member, whereby said elastic covering will be expanded in said member by atmospheric pressure, and means operable by axial movement of said open ended member for again admitting air to said member.

5. In apparatus of the character described the combination of a cabinet, an open ended member disposed within said cabinet and movable with respect thereto, said member having a rim projecting out of said cabinet over which the cuff of a glove may be stretched when said rim is in its outermost position, and means disposed about the projecting rim of said member for displacing the cuff of the glove from said rim when said open ended member is moved inwardly into said cabinet.

6. In a rubber glove applying device, the combination of a support, an open ended glove support- Y ing member movably mounted upon said support, said member when in another position, and

said member being adapted to receive a glove with its cuir in sealing engagement across the open end thereof, means for exhausting the air from said member when a glove is disposed thereon to expand the glove and permit the insertion of a hand, a valve for connecting the rinterior of said member to the means for exhausting the air therefrom when in one position and admitting air into means cooperating with said member for operating said valve when said member is moved upon its ,support by the hand within the expanded glove, whereby the air exhausting connection will be broken and air will be admitted to said member AandV permit the glove to contract upon the hand inserted therein.
