CABINET FOR POWDERING AND TURNING INSIDE-OUT OF RUBBER GLOVES Filed Jan. 28, 1938 Patented May 16, 1939 UNITED STATES CABINET FOR- POWDERING AND TURNING INSIDE-OUT OF RUBBER GLOVES Application January 28, 1938, Serial No. 187,428
The invention relates to a dust proof cabinet of sheet metal used for the powdering of surgical rubber gloves, as used in hospitals by doctors and nurses. The powder on gloves permits them to be slipped on easily and keeps hands comfortable by absorbing moisture while being worn.
The object of the invention is to confine to a small enclosed space the dust created by the powdering with talcum powder and turning inside out of surgical rubber gloves, preventing contamination of the atmosphere, and thereby safeguarding the health of workers.
In the drawing:
Figure 1 is a view in perspective of a cabinet constructed in accordance with an embodiment of our invention;
Figure 2 is a front elevational view of the device as illustrated in Figure 1 with the front wall omitted;
Figure 3 is a fragmentary detailed sectional view taken substantially on the line 3-3 of Figure 1;
Figure 4 is a fragmentary detailed view partly in section and partly in elevation of the mounting of the electric lamp as herein embodied.
The rectangular cabinet is entirely closed except for the door I in lower part of front wall.
A glass window 2 in upper part of front wall permits operator to watch her work.
In the lower part of front wall is a double door I, fitting well into opening 3 which is shown by dotted line in Fig. 1, and is rendered dust proof. by a strip of felt 4, fastened along inside of edge of door. Metal hinges 5, 5, 5 hold door in place at the bottom of cabinet, and metal catches 6, 6 are used to close the door. Talcum powder and gloves are placed into cabinet through this door.
Two round holes I, I allow operator to introduce hands and lower part of arms into interior of cabinet after door is closed. Two canvas sleeves 8, 8, fitting operators arms on outside of cabinet loosely enough as not to cause discomfort, prevent dust from flying out of cabinet during powdering procedure.
There are two shelves 9, 9 fastened to the inside of cabinet by means of hinges I0, Ill. The shelves fold upward and are held when in upright position by means of hinged supports l I I I and brackets l2, [2. When folded down, shelves meet in center of. cabinet, forming a complete surface. When in this position, shelves are supported by strips of metal I3, I3. Position of supports 1 I, II, when shelves are in this position, is shown by dotted lines on right hand, side of Figure 2.
With shelves in upright position gloves are shaken around in talcum powder in bottom of cabinet until they are sufiiciently powdered. After gloves are powdered, they are placed in right hand side of cabinet; left hand shelf is brought down to horizontal position; excess powder is shaken off gloves; they are placed on shelf. Then right hand shelf is brought down forming complete surface on which to work. The gloves are turned inside out, one by one, and placed on right hand shelf. The left hand shelf is brought into upright position and all gloves are put back into talcum powder on floor of cabinet. The right hand shelf is brought into upright position. Hinges l0, ID are offset to allow a small space between shelf and cabinet, so that powder collectedon shelves while turning gloves slides back into bottom of. cabinet as soon as shelves are brought into upright position, rendering shelves self-cleaning. The second powdering is done in same manner as first one described above.
After second powdering is completed, one shelf is brought into horizontal position, excess powder is shaken off gloves, and they are placed on shelf.
Operator removes hands from cabinet and al lows powder to settle for a short time, after which the gloves may be removed.
Our invention is intended to be used in hospitals. The rubber gloves worn by doctors and nurses during operations and treatments must be lightly coated with talcum powder. The present procedure of powdering gloves is to sort them according to sizes, place them upon a table, turn them around in a heap of powder, shake off the excess powder, turn the gloves inside out, repowder them, and pack gloves into muslin covers, one pair to each cover. The packages are then ready for sterilization or unsterile use. Large hospitals powder from two hundred to three hundred or more pairs of gloves daily and during this work an enormous amount of dust is created contaminating the atmosphere and settling on clothing, furniture and floors and thereby endangering the health of all workers in the room. The person doing the powdering quite frequently suffers from loss of appetite and respiratory infection in spite of protection afforded by wearing a face mask. The disadvantages of this present method are clearly overcome by the present invention as the cabinet serves to confine the dust created during the powdering a p in of the gloves. With the use of our improved cabinet no separate room is required, no masks need be PATENT OFFICE worn, and aprons and caps are not required for the protection of hair, clothes, etc.
The cabinet is illuminated by an electric lamp l4, fixed to center of top wall inside of cabinet by means of a porcelain and metal fixture [5. The cable IB is led through a bushing I! to outside of cabinet. The light is operated by means of a switch 18 in cable on outside of cabinet. A plug Is at end of cable connects to wall. .A half shade 20 on light protects eyes of operator.
