PRocEss OF TANNING.
Specification of Letters Patent.
Patented Jan. 1c, 1908.
Application filed June 25- 1907- Serial No. 380.785.
To all whom it may concern: Be itknown that I, GEORGE ,I-l. PENDLE- I ,ToN, a citizen of the United States, residing three hours'until the hair slips easily. It is then washed in clear water, and'the hairis out thoroughly.
water until they become They are then placed on a cam and all the at Busch, in ,the' county of Roger Mills and loose fleshis removed after which they are thoroughly'washed in warm soapsuds. The
hides or pelts are thus prepared for the solution for removing the hairo'r for tanning with thehair on. If the hairis-tobe removed, the
pelt is placed in strong liine water for two or removed in the Well known manner, care being'of'course' taken not toibreak' the grainofthe hide. 1 The lime is then soaked or washed In certain portions of the country where the Water is impregnated with gypsum, to
' four gallons of Water is added one-fourth of an ounce of sodium carbonate and one-fourth of an ounce of ammonia. These ingredients are boiled toge thcr for live minutes and serve to 'actupon the gypsum in such a manner I that it will have no deleterious effect on the hereinafter described tanning bath and process. IVhere pure water is obtainable, the above step is of course not necessary. Afterwards two pounds of gum gambier, placed in a small sack of thin muslin, is introduced thereint-o and is boiled tl'ierewith until a pure reddish color is obtained. The'bath is'thereuponellowed to cool to a temperature that will not burn the hidesor pelts, and said hides or'pelts are then introduced, sullicient both being employed to cover the same. They are allowed to remain in this bath from six 'to twenty-four hours, according to their size, and the pelt then scraped off in the usual manner. After the hides or pcltshavc been thus subjected to this preliminary bath, onefourth ounce of gumarabic one-fourth ounce of oil of hops and one-fourth ounce of fluid extract of wild cherry bark of the character described in the U. S. Pha-rn'zecopce'ia are stirred Well into the above described 3 bath.
The hides are then placed in this final bath, and are allowed to remain until thoroughly tanned which will take from three to fifteen days according to the thickness of the hide. Finally upon the removal of the hides or pelts, they are oiled with fish oil on both sides. The result is excellent leather that can be employed for any well-known purpose.
There are a number of advantag es for the method above described I no machinery .is necessary for smoothing the leather after the same has been tanned, for in the present process the soda and the mixture of the extract of wild cherry bark,
oil of hops and gum arabic, makes the leather] slick and smooth without the use of rollers.
The hides are carefully prepared. The annmonia eliminates all greases from the skins, and the soda and gum gambier together 'roduce an excellent color, besides preservmg the grain of the leather andjicausing the )elts to relax so that, the pores are open. The final bath enters these pores and constitutes' an excellent preservative for the fibers of the leather. Moreover the ingredients employed are not of an acid' nature, and will In the Iirstplace,
hot burn or otherwise injure the hides while 1 tanning the same. v Having thus fully described my invention,
what I claim as new, and desire to secure by thchide or elt into a bath containing a tan ning and co oring material, allowin it to remain therein for a period of time, afterwards adding gum arnbic, 'oil of hops and extract of cherry to said bath, and allowing the hide or pelt to remain in "he final compound until tanned.

The process of tanning hides, pelts, and the like, which consists in softening the hide 'or pelt, introducing the same into a, bath consisting of water, 2m alkali, ammonia, and a coloringand tanning materiuY, allowing it .to remain therein, then adding to the bath gum arabic, oil of hops and extract of wild cherry, and allowing said hide or pelt to remain therein until tanned. 1
3. The process of tannins hides, pelts, and
" the like, which consists in Iirst softening the hide or pelt and removing the flesh therefrom,
preparing a prcliz ninary bath by boiling togct icr water, soda and ammonia, afterwards adding gum gambler and boiling the same,
allowing the bath to cool, placing the hides i In testimonlz, that I claim the foregoing or elts therein for a' predetermined period, I as my 0wn, I eve hereto afiixed my signaad ing to said bath, guni arabicyoil of ho s ture in the presence of two Witnesses. and extract of wild cherry, allowing the hi e' GEORGE H. PENDLETON. 5 or elt to remain-until tanned, removing the Witnesses:
