by means of two compound levers which are secured in position by a special form
of sensitive solder joint or connection.
My present improvements consist in the arrangement use and application of
three or more compound levers in combination with the valve face and sensitive
solder joint and in substitution for the arrangement of two compound levers shown
and described in my aforesaid Specification.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is an elevation and Fig. 2 a vertical section of an automatic fire
extinguishing sprinkler constructed substantially as described in my aforesaid
Patent Specification and to which my present improvements are applied, and
Fig. 3 is a sectional plan view on the line A B, Fig. 2.

page_text: In these views, a represents the body of the sprinkler; the cover which is
threaded onto the body a; c represents the distributor; d the stem which is
attached to the distributor and supports it in its proper position when the sprinkler,
which is shown in its closed position, is open, by means of a gallery e secured to
the body of the sprinkler; represents the upper or primary lever which is
shown of a channel section, one end of which is supported by the internal lip b¹ of
the cover b and the other rests upon an intermediate or secondary lever g; one end
of the lever y is supported by the internal lip and the other end rests upon the
third lever h. The lever is supported by the internal lip b¹ at one end and at
the other is held in position by means of a sensitive joint or connection formed of
flanged metallic tubes and fitting one within the other and soldered together
with sensitive solder and insulated by non-conducting washers for metallic contact
with the parts of the sprinkler to which they are attached substantially as described
in my aforesaid Patent Specification.
