To {LZ/Z whom/jt may concern:

Be it known 'that I, HENRY CorlLovicH, a

citizen of the/United States, residing at Hincklcy,lin the county of Pine and State of Minnesota, have invented certain new and useful linprovementsin Turpe'ntine-Stills, of which Ithe following is a specification.`

This invention provides :li/novel apparatus for collecting turpentine in the destructive AIO distillation of wo'od as well as saving the by-` products, such as tar and the oil thereof.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the' following description and accompanying drawings, in which Figure lis alongitudinal section of an a'pparatus embodying the invention. Fig. 2 is a horizontal section of the retort and furnace on the line or of Fig. 1.

Corresponding'and like parts are referred to in the following description and indicated erected thereon'.

closed at its'4 ower end thereby.' Thel inclinedwalls 2 ofthe .furnace gradually ap'- proach thel shell' at their upper ends and touch the sidesl thereof, forminga space 7,. which' tapers toward its; upper end. and
