Improvements in valves for the circulation of hot water (1876/2994)

On 25th July 1876, he submitted a patent application for which he was initially was granted a six-month long provisional protection for his invention for “improvements in valves for the circulation of hot water, which improvements are also applicable to the circulation of cold water, gas or other fluids[1]. The patent was subsequently sealed on 5th January, 1877, of which the following is an extract:-


Valves for the Circulation of Hot Water, &c.

My improvements consist in the first place in forming a chamber with two or more valve seats and valves constructed of brass, iron, india-rubber, or other suitable material, to open and shut upon the seatings, as desired.

Secondly. In securing two or more valves to one or more spindles which pass through a gland or glands into the chamber containing the seatings, the said spindle or spindles form the hinge or hinges of the valves. This spindle or spindles is or are acted upon by a handle, one or more toothed quadrants, worms and wheels or their equivalents, the said quadrants may be fixed either inside or outside the chamber, as desired.

Thirdly. By the foregoing means the valves can be arranged in such a manner that the operator can open two valves in a direct line of pipes, and close a third by the same operation on the seating of partition across the chamber, which causes the water to flow on over the top side of the chamber to the end of the system and return back under the partition to the boiler; or by closing two valves in direct pipes the one in the partition is opened when the water returns through this port, so that the chamber forms what is commonly called a syphon, as indicated by the arrow; or when required without a partition, and to fix a valve or valves at each end of the chamber, one or more valves are connected at one end of the chamber to the corresponding valve or valves at the other end of the chamber, acted upon by a worm and wheel as before described, so that when a valve or valves is opened the corresponding valve or valves is closed, or both may be so adjusted that the valve or valves at both ends may be partly open and allow free circulation from both of the ends of the chamber through a pipe or pipes from the boiler into the said chamber.

Fourthly. The said chamber or· chambers is provided with a lid or lids, or covers, to allow of access to the valves for cleaning or repairs without disturbing the pipes.

Fifthly. If desired, I cast with or secure to the said chamber a second chamber or water space, upon which four or more sockets or flanges are cast or secured to receive as many pipes so that after the water passed the valve or valves it circulates through as many pipes as are provided for on the chamber or water space.

In the accompanying Drawings Figures 1, 2, and 3, are perspective views of the various modifications of my Invention; and Figures 4, 5, and 6 are sections of the same; the same letters of reference indicate like parts in all the Figures.

A are the valves in a direct line of pipes; B, valve in partition; C, sockets to receive the pipes; D, worm; E, wheel or handle; F, spindle; G, quadrant; H, gland; I, lid.

Having thus described my Invention I claim,-

First. The employment of a chamber for one or more valves to work in simultaneously by one operation.

Secondly. In forming a partition in the said chamber, on which a valve works as before described.

Thirdly. The employment of one or more spindles, arranged and actuated as desired.

Fourthly. The employment of a second chamber to receive as many sockets or flanges as may be desired, as described, to receive the water from the valve or valves.
