J.H.LYNDE. AUTOMAT IG FIRE EXTINGUISHING SPRINKLER.
Patented Oct. 17, 1893.

UNITED STATES PATENT OFFICE.
JAMES HENRY LYNDE, OF SALE, ENGLAND.
AUTOMATIC FlRE-EXTINGUISHING SPRINKLER.
SPECIFICATION forming part Of Letters Patent N0. 506,704, dated October 17, 1893.
Application filed October 24, 1892. Serial No. 449,844. (No model.) Patented in England December 19, 1889,1I0. 20,421.
To all whom it may concern:
Be it known that 1, JAMES HENRY LYNDE, a subject of the Queen of Great Britain, and a resident of Sale, in the county of Chester, England, have invented certain new and useful Improvements in Automatic Fire-Extinguishing Sprinklers, (for which I have obtained Letters Patent in Great Britain, numbered 20,421, bearing date December 19, 1889,) of which the following is a specification.
My invention relates to improvements in automatic fire extinguishing sprinklers and the object of my improvements is to produce a sprinkler of strong and simple construction capable of withstanding high pressures of water and of the highest degree of sensitiveness practicable.
My improvements are particularly applicable to the construction of sprinklers for which I have obtained Letters Patent in Great Britain numbered 18,457, and dated December 18, 1888.
In performing my invention I use compound levers or other devices for the purpose of maintaining a valve face in close contact with a valve seat. When I use compound levers one end of the secondary or last lever is supported on a lip inside the cover or by other part of the sprinkler and the other end of the lever is according to my invention secured in position by a special form of sensitive solder joint or connection as hereinafter described and pointed out in the claims.
In order that my invention may be fully understood and readily carried into eifect I will describe the accompanying sheet of drawings reference being had to the figures and letters marked thereon.
Figure 1 is a side view of the sprinkler (closed). Fig.2 is a side view of the sprinkler (open). Fig. 3 is a section of the sprinkler. Fig. 4 isa cross section of the compound levers. Fig. 5 is a view of the top of the sprinkler. Fig. 6 is a view of the under side of the sprinkler.
Similar letters refer tosimilar parts throughout the several views.
In the views,-ct represents the body of the sprinkler, b the cover which is threaded on to the body a;
0 represents the distributor; d the stem which is attached to the distributer and supports it in its proper position when the sprinkler is open by means of the gallery 6 to which it is secured.
f represents the upper or primary lever one end of which is supported by the internal lip 19 of the cover I) and the other rests upon the sec ondary lever 9 one end of which is supported by the internal lip 19 and the other end is held in position by means of the flanged tubes In and Z which are soldered to one another and are supported in the bracket h which is part of the cover 12. Between the bracket h and the flange of the tube and also between the end of the secondary lever g and the flange of the tube Z washers i made of material having a low power of conducting heat are in serted. By these means I insulate that por-- tion of the sprinkler which forms the sensitive joint from metallic contact with the body of the sprinkler and so reduce to a minimum the weight of metal that must necessarily be heated up to the melting point of the sensitive solder and thus render the apparatus more sensitive to heat than it otherwise would be. I form the sensitive connection of tubular shape in order to secure the greatest strength with the smallest weight of metal and also in order that in case of a fire the heat may be communicated both internally and externally simultaneously, .thus providing as large a heating surface as possible.
Having. now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim, and desire to secure by Letters Patent of the United States, is-
1. In an automatic sprinkler, a sensitive joint or connection formed of flanged metallic tubes fitting one within the other and soldered together with sensitive solder and insulated by non-conducting material from metallic contact with the parts of the sprinkler to which they are attached.
2. In an automatic sprinkler a fusiblejoint comprising a tubular connection sensitive to heat and having a free interior and open ends and the non conducting material arranged to insulate the said connection from the metallic parts of the sprinkler, said material extending around the outside of the tubular connection substantially as described.
In witness whereof I have hereunto set my hand in presence of two witnesses.
JAMES HENRY LYNDE.
