generated in the heated timber,
and the air from the tank. The pores of the wood being thus rendered
vacuous, the hot liquid or vapors from the heating tank readily
penetrate the entire substance, and thoroughly impregnate it. This
apparatus is the invention of George Pustkuchen, of Hoboken, N. J.

BOARDMAN'S COMBINED TOOL.

This tool, of which our engraving is a good representation, comprises
a screw wrench, a pipe wrench, a hammer, a nail claw, a screw-driver,
and a bit handle, or socket wrench.

The bit handle is the entire tool, the square socket or opening being
made in the end of the handle, in which the shanks of bits may be
inserted.

The screw driver is formed on the end of the screw bar, attached to
the outer jaw of the wrench, and is taken out from the hollow of the
handle when required for use.

The use of the other parts of the tool will be apparent from the
engraving.

The tool is very compact, and has this advantage over the ordinary
screw wrench, that its leverage increases as it is opened to receive
nuts of larger size.

This invention is protected by two patents, dated respectively, May
30, 1865, and July 10, 1866.

BELT TIGHTENER.

[Illustration]

This instrument will be found of great service in bringing together
the ends of belts, the weight of which is so great that they cannot
be held together by the hand while lacing. A strap engages with holes
made in the belt, at the back of the holes punched for lacing, the
tightening strap being provided with claws or hooks, as shown. A winch
axle and ratchet, adjusted in a frame as shown, are then employed
to pull the ends of the belt together and hold them firmly till the
lacing is completed.

This is the invention of T. G. Stansberry, of Medora, Ill. Patented in
September, 1867.

SOME THINGS I DON'T WANT IN THE BUILDING TRADES.

I don't want my house put in repair, or rather out of repair, by a
master who employs "Jacks of all Trades."

I don't want my foreman to tell me too much at one time about the
faults of the workmen under him, as I may forget asking him about
himself.

I don't want a builder or carpenter to give a coat of paint to any
joinery work he may be doing for me, until I have examined
