"Letters Patent No.102 ,868, dated May 10, 1870.
IMPROVEMENT IN BLEAGHING STRAW G-O OIDS.
The Schedule referred ,to in these Letters Patent and making part of the same I, AMANDA M. RosBnnGH, of Panora, in the county of Guthrieaud State of .Iowa, have invented certain "be operated upon.
.The drawing is a perspective view of a half section of my bleaching box, representing the stove or fire.- box, and all the doors, fastenings, glass windows, and.
AA is the wall or frame of the box.
B is the hinged cover of theboxz (l 0 represent the glass windows, one of which is in the hinged cover, and another in the front wall.
Other glass windows may-be placed in the ends of the box or wherever desired.
means of access to the stove or'fire-box.
E E isthe stove or fire-box, made of sheet metal, in a square form. This store may be made of cast metal, and of various forms. p
G is a ventilator by which the draught and fire'in the stove may be regulated. V d f H is a door in the front of the stove to admit'the uel.
I I is the pipe of the stove. The hinges and fastenings of the several doors are such as commonly used for similar purposes. I
(Va represent one of the movable bars upon which D is a door in the front of the box providinga the articles are suspended.
- "b' is a straw hat suspended from the bar.
To perform the bleaching process a fire of charcoal or its equivalent is required in the stove. All articles to be bleached must be well cleaned with soft water and good hard soap. "All straw goods must he coated on both sides with a paste made of pure white corn -meal ahd a strong solution of bicarbonate of soda and soft water; The articles are then' ready-to suspendin the box. White thread or cord must be used to secure them. For woolen goods and other textile fabrics the paste, composed of pure white coru-me:il,
and subjected to further-smokingprocess.
' claim as new.
and a strong solution-of bicarbonate of soda, shouldbe made thin enough with soft water to admihof its being strained through white flannel. Leave It in this state twenty or thirty minutes before straining. With the fluid thus produced the articles must be well saturated before being placed in .the box. After the articles are in the box, place pure roll-briiustone, broken into particles, on the top of the stove, and start the fire in the stove Close the box securely. the glass windows you can observe the bleaching .process. The smoke of the brimstone will permeate the goods, and first turn it yellow andthen white. For
old goods. the smoking process must be continued from six to twelve hours. For new goods less time is required. If any part of the goods vis imperfectly bleached it should be again treated as before directed, By the use of the glass windows the condition of the goods can be seen, and the further continuance of the process may be thereby determined.
My bleaching-box is made of wood, and may vary in form and size as desired, and may be movable or permanently fixed. v
Iam aware that boxes have been used, and that -brin 1stone has'beeu burned in them for the purpose of bleaching. But they havebeen rude, inconvenient, andimperfect, and poorly adapted to the purpose. My bleaching-box differs from them by being complete in all its parts, as specified, and by providing windows through which the process may be-ob served. 1 am also aware that corn-meal has been used forbleaching purposes. But my manner of using it, in connection with bicarbonate of soda, I.
Q'lm'ms. I claim as my invention- 1. The bleaching-box,\vitl 1 hinged cover B, glass windows O 0, door D, stove E E, and movable frames a a, as described and for the purposes specified.
V 2. The use of bicarbonate of soda in the process of bleaching, substantially as descriEed.
