To rz/ZZ w/mnt it 'limy (o/worn:

Be it known that I. ISRAEL EisnNsTmN, a

citizen of the United States, residing at New .rork. 1n the borough of Manhattan and State 3 of New York, have invented certain new and useful Improvements in Methods of Finishing (lanes and the Like and. Articles Produced Thereby; and 1 do hereby declare the following to be a full, clear, and exact description of the invention. such as will enable others skilled in the art to-which it appertains to make and use the same.

This invention relates to the method of linishing bamboo, tonquin,.and reed sticks.

The objects of the invention are to produce bamboo, tonquin, or reed canes with an enameled surface produced by baking the paint, varnish, or other coating on the body of the cane, whereby the enameled surface is produced which is practically impossible to scratch or remove. Hcretofore attempts have been made to linish bamboo, reed, and tonquiu canes with a suitable paint or varnish; but all such attempts,=so far as I am aware, have proved. impractical or unsuccessful, owing to the diificulty of securing a firm contact oi the coating material onto'the glazed or natural covering of such classes of sticks.

7 It is a common practice to sandpaper and polish hard wood and other sticks possessing a porous and a natural unglazed surface; but this class of wood is totally difi'erent from sticks or reeds having a natural glazed or sheal covering, such as is found on bamboo, reed, and tonquin sticks. 'It has been found impractical to bake varnish 'or paint on porous naturally-unglazedflsticks, owing to the fact that the sticks are injured and praeti-- cally destroyedlby-such baking. Owing to the natural consistency of bamboo, tonquin, and reed sticks the same are not injured by the baking, and by the use of a specially-prepared varnish or coating which I. have devised 1 am enabled to finish such classes of canes with a hard enameled surface-a result which, as far as I am aware, has never been. heretofore successfully accomplished.

In carrying out the method employed in producingthe finished surfacc on canes of such variety I make use of the mechanism illustrated iiftl'ie accompanying drawings. in which i Figure lis a perspective view of the receptacle for containing the composition used for coating the canes and the draining receptacle employed. Fig. 2 is a perspective view, shoWn l partly in section, of a cane-carrying member which is adapted to be positioned within the reco 'itaclc depicted in Fig. 1 for covering the canes with thecomposition employed for coating the same. Fig. 3 is a perspective view of a member constituting a weight. Fig. i is an elevated front view of the furnace in which the unfinished canes which are coated with the composition contained in the receptacle depicted 'in Fig. l are to be baked for cnameling the same. Fig. 5 is a longitudinal sectional view of a finished cane constructed. in accordance with the present invention.

The varnish paint preferably employed in the present invention comprises caoutchouc, six parts; rectified spirits of turpcntine.twel re and one-half parts,:md rectilicd slrule-napdmtha, fifteen parts. The mentioned three ingrcdicuts are then stirred and heated on a sand bath. I then take of the above mixture sevventy-five per cent. and mix therewith pale boiled oil seventy-fire per cent. and pale copal varnish one hundred percent. This mixture of all of the ingredients is then heated to 190" from ten to twelve hours. The coloring-mattor for the varnish is mixed belore heating.

After the varnish has been made the desired amount is'deposited in the receptacle 1. The body 2 of the canes. which is formed of bamboo, tonquin, or reed sticks, is then placed within the cane-carrying member 3. aid member 3 comprises a frame which is provided with parallel members 4:. secured to the lower portion thereof. 'lhcmcmbers at constitute the bottom of the member Each member a is provided with upwardly-projecting pins Each of said pins 5 is engaged by the lower end of the body of an m'iiinished cane. The upper end of the member 3 is closed by netting 6. preferably Formed of metallic material. \Vithin each mesh of the cover 6 one of the unfinished canes is positinned. It is desirable that the covering 6 be provided with the same number of meshes as there are pins secured to the transverse members a in the lower portion of the frame of the cane-carrying member 3. An unfinished cane is secured Within one of the mesl'ics of the covering t' and upon one of the pins 5 of a member i. When the cane-carrying member 3 is positioned within the receptacle 1, it has been found tha the canes will' lloat if they are not w ighted down. and to obviate this rcmovai oi the canes from within the carrying member I employ a weighted member 7, preferably formed of metal, which is positioned upon the com pr handles of the cane-bodies for pressing them down and retaining the same within the mesh lift the same and move it over the receptacle 'l and subsequently lower the same into said receptacle for immersing the bodies of the canes in the varnish Contained within said receptacle; After the canes have been covered by the varnish the-'cane-carrying member 3;

is then lifted and positioned over the drainjug-receptacle 10 and lowered upon the frame 11 supported thereby. The frame 11 is positioned above the receptacle 10. Frame 11 allel sides and ends and a transverse connecting member 12-. The cane-carrying member 3 is rested upon the frame 11, carried by the draining-receptacle 10. for permitting of the cane-bodies to be drained before the cane-carrying member containing the cane-bodies is placed in the oven of the furnace 13 for baking the varnish uponthe canehodies for producing an enameled coating thereon. it will be obvious that the caneb'odies al t'e they have been varnished maybe traveling pulley by means.

removed from the cane-carrying member 3 and separately placed in the oven for baking the varnish placed thereon. bodies may be supported in the oven at each of their ends ormay be suspended by means of their handle structure upon any suitable support. in the'eventof gases accumulating in the fUIIlllCQ I have provided a valve 14k, which is actuated by a flexible member 15, for permitting of the escape'ot said gases.

The glazed or substantially non-porous sur: face of the bamboo, tonquin, or reed sticks is entirely covered by the enameled coating 15, formed by baking the varnish in the even of the furnace 13. The body of the cane after it'has been coated with my improved varnish placed in the oven as specified and the temperature in said oven maintained from about 20)" to 300 of heat for not less than three hours.

I have found by numerous tests that it is practically impossible to secure a finish on a glazed reed, bamboo, or tonquin stick unless The cane- &

the heat is raised to a temperature-0t not less than 200 and not over3O0 for a period of not less than three hours. It the canes are subjected to a heat of more than 300, the same will be so injured as to beuseless for practical purposes, and if subjected to heat for less than three hours the varnish paint will not be properly baked onto theglazed surface. It is impractical to bake ordinary wooden sticks which are not provided with a natural glazed surface, for the reason that said sticks cannot withstand the heat to which they are subjected during the process of baking the varnish paint thereon. My invention does not relate to the finishing of this class of sticks. The object which Ihad in mind and whichl have successfully accomplished and which I' never known to have been successfully accomplished .by any oth eu'was to provide-a method by which the finish could not be scratched after the baking operation is completed. The result. I have obtained was accomplished after to the degrees of heat and the length of time the'heating should be continued.

1 do not Wish to limit my invention to any particular mechanical means for carrying out the method or to the particular ingredients employed in the varnish-paint composition,

though those which 1 have set forth I have found to be practical for carrying out the method, as the present invention has reference entirely to the method of finishing bamboo, tonquin, and reed sticks. i

1. The herein-described method offinishing bamboo, tonquin and reed sticks Which-consists in coating the same in their natural st'a te with a suitable baking varnish paint'and' subjecting the coated sticksto a temperature of from 200' to 300" of heat for not less than three hours.

2. The herein-described method of finishing bamboo, tonquin andreed sticks which consists in coating the samei n their natural state with a suitable'baking varnish paint and subjecting the coated sticks to a temperature of from 24:0 to 300 of heat for not less than three hours. i

In testimony whereof I afiix my signature in presence of two Witnesses.
