thereof; and the other has a faucet, by which the water is drawn off
as occasion requires. They may be found at 156 Delancy street.

=Improved Yoke for Oxen.=

This yoke is constructed with sliding blocks attached to the under
side of the beam of the yoke, near each end, and each sliding block is
attached to the beam by bolts which pass through mortises so that the
blocks may be made to slide occasionally to the right or left. To
these blocks are attached the bows, the position of which are adjusted
by gauge screws; and by the sliding of the blocks, the distance of the
oxen from each other may be regulated. The middle of the yoke is
furnished with a draught staple or eye-bolt which is moveable and
regulated by a hand screw at the top, whereby the _pitch_ of the
draught it regulated. Invented by David Chappel, and entered at the
Patent Office, Sept. 3d.

=Another Improvement In Stoves.=

Messrs. Hartshorn, Payson & Ring entered at the Patent Office,
September 3d, an improved stove, in which they claim the combination
of the common wood stove and cylinder coal stove, so that the coal may
be burned alone, and the draught so arranged as at the same time to
heat the wood stove with the same heat, and if wood alone should be
burned, then the draught should be so managed and arranged as at the
same time to heat the side radiators and coal cylinders. A minute
description of this improvement, is not, in this place, essential.

=Iron Shingles.=

We have never been able to understand the reason why iron has so long
been neglected as a covering for roofs, but are gratified to learn
that Mr. Wm. Beach, of Troy, N. Y., has invented and patented a mode
of using cast iron plates for covering roofs. They are about one foot
square, and are made to fit one into another, so as to render the roof
water tight, by applying white lead to the joints. It can be afforded
at 16 cents the square foot, and probably may be so far improved as to
cost no more than slate, and will be much more permanent and safe. We
see no difficulty in dispensing with white lead, however, and making
the seams tight without it.

=Improvement in the Railroad Track.=

This improvement was entered Sept. 5th, by John F. Rogers. What he
claims is the combination of the balance beam with the centre beam, by
means of the recesses in the centre beam, spring plates, having tubes
thereon on which the springs rest, and attached to the beam by bolts,
