JAMES HOWORTHS Patent Revolving Archimedian Screw Ventilators,
For Ventilating Buildings , and Preventing Down-Draughts and Sulphurous Smells in Chimneys .
These Ventilators are of various sizes, suitable far Public Buildings, Private Residences, Outhouses, and every description of Works, and for Preventing Down-Draughts and Sulphurous Smells in Chimneys. Through the application of the ARCHIMEDEAN SCREW, perfect Ventilation is secured, without the possibility of Down-Draught. They are guaranteed to be in perfect working order for six years and upwards, without re-oiling, or any attention whatever, if properly fixed.
For the effectual Ventilation of Sewers.
Advantages of the Ventilator. —i. By the motion of the Screw a continuous up-current is produced, by which means hot vitiated air, steam, or dust is removed from the room. 2. The Screw producing a continuous up-current, prevents the admission of cold air or dust down the Ventilator; consequently no Down-Draughts are felt, which are so injurious to health, and so uncomfortable to sit under. 3. The working arrangements are so sensitive that the least wind will cause the Ventilator to revolve, producing a change of atmosphere in the room in all weathers.

Tried and reported upon by the Editor of the “ Field, M as follows:—
“We have carefully examined this Gun, and can strongly recommend it to our friends for trial, believing it to be on a very excellent and simple plan of construction, while the safety bolt is so strong and efficient, that with only moderate care the chance of an accident from unpremeditated discharge is reduced to a minimum.”—Vide Fields 6th July, 1872.
