COMPLETE SPECIFICATION.
A New or Improved Frame for Supporting Thermometers in
Greenhouses, Conservatories, and other Buildings.
We, WILLIAM SUTTON, of Petworth Park, Petworth, Sussex, Clerk of Works, and
EDWIN WALTER PULL, of the same place, Head Gardener, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The object of our invention is to effect improvements in the method of supporting
thermometers for use in indicating the temperature of greenhouses, conservatories,
and other buildings.
According to our invention we mount an ordinary thermometer in a frame, such
frame being provided with pointers for indicating and recording the temperature
at any time, and thereby affording facilities for regulating and securing the required
temperature.
And in order that our said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation of the frame.
Fig. 2 is an elevation showing the thermometer mounted on the frame.
Fig. 3 is a side view of Fig. 2.
The frame is formed of metallic bars, a a, pivoted together in the same manner as
lazy-tongs, and capable of extension either longitudinally or transversely. At the
upper end of the frame a disc b is fitted, having a suitable scale of temperatures
indicated thereupon; also the words "Sun heat and having also an indicating
hand or pointer & fast on the projecting pin c, by which the pointer may be turned.
dd are two wires attached to the pivots at e e.
The lower ends of these wires are
carried down and pass through holes formed in the lugs ff. gg' are two pointers
(having thereon the words "Day" and "Night") capable of sliding up and down
the wires d d so as to point to any degree of temperature indicated by the scale g
being used for the day, and g₁ for the night. h is an ordinary thermometer
sustained by the pin c, and held between the wires dd, the pointers 9 g, projecting
over the scale, as shown in Fig. 2.
In using the invention, the frame and thermometer are hung upon a nail or peg
in the conservatory or other building. The hand k is then pointed to the temperature
indicated by the heat of the sun at the time of observation. In like manner one of
the pointers g may be used to mark the minimum temperature and the other to mark
the maximum temperature to be permitted. The indicators may obviously be
otherwise applied.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved frame for supporting thermometers for use in indicating the
temperature of greenhouses, conservatories and other buildings, substantially as
herein before described and illustrated by the drawings.
2. In an appliance for use in indicating the temperature in greenhouses,
conservatories, and other buildings, the combination of a frame formed upon the

page_text: lazy-tong principle, carrying a dial b, pin c, pointer k, wires d,-pointers g, and
thermometer h, substantially as herein before described and illustrated by the
drawings.
