FREDERIC WELLER KENDALL, of No. 65, Cloudesley Road, in the Parish of
Islington, in the County of Middlesex. "AN IMPROVED VENTILATED GLAZED
GARDEN HAND FRAME."
The efficacious ventilated propagating glazed garden hand frame, while differing
from all others now in use, is intended to supersede the old frame by becoming a
safe and sure protector and propagator of every description of young tender plants
and seedlings, so desirable for their culture and growth, affording such advantages
to horticultural, cottage, and other gardening, that this Invention must and will
prove a great public benefit.
1st. The said ventilated propagating hand frame will be manufactured in every
available size and shape; the framework will be machine made, of a peculiar pattern
(as shewn in section on the Drawing) of imperishable metal, or of lead, tin, copper,
brass, zinc, or any other maleable substance, and glazed, as shewn on the Drawing,
& fitted with a ventilating apparatus composed of the same imperishable metal,
or of lead, tin, copper, brass, zinc, or any other maleable substance, formed of two
thin sheets or discs of metal fitted and fixed on top of the hand frame & .imme-
diately under the handle, and 4 small holes, 1 each side, drilled through the bottom
rim of the metal frame, as shewn on the Drawing; the metal discs or plates are
made to revolve one upon the other by means of a centre spindle and knob which
opens and closes the valves at pleasure by giving the knob a circular motion with
the hand, and is by no means easily put out of order without great force.
2nd. The great desideratum of this Invention is to supply the horticulturist, the
cottage, and other gardeners with a pure and health-giving glazed garden hand
frame for the safe and sure protection and propagation of young tender plants and
seedlings, so much needed for the supply of early productions of valuable plants and
flowers without the fear of sacrificing both time and labor as well as the plants, so
often the case with the present old hand frames, in having to lift them up for the
expulsion of the foul pernicious air confined and engendered under them, and at
the same time admitting a great rush in, or too great a quantity of cold air equally
injurious to the plants by greatly checking their growth and often destroying them

page_text: altogether. This Invention therefore possesses the means and the power of dis-
persing this confined impure air effectually without lifting or removing the said
frame in the least, and admits the pure and fertilizing external atmosphere in a
genial form, preserving the plants from all danger of injury which they are subjected
to by the old fashioned hand frame.
3rd. These ventilated hand frames, by this Invention, can, from the construction
of the metal work, be supplied at prices equally as low as those now charged for
the old fashion frames executed in similar metal, and the broken glass can at all
times be reinstated by any unskilled person, as also the ventilating apparatus can
very easily be replaced by a new one at a trifling cost.
