WATER-CIRGULATOR For: corneas T 0 all whom it may concern M I Be it known that I, J OHN'TAIT, engineer,
a subject of King George V of Great Britain, residing at 3 Dowling street, Dunedin, in the Dominion of New Zealand, have invented new and useful Improvements in IVaterCirculators for Boilers, of which the following is a specification.
The object of the invention is to create a more efficient circulation of water in a boiler and so equalize the temperature that steam may be generated rapidly without any danger of undue straining. The means provided add greatly to the life of the boiler and effect great economy in repairs, and saving of fuel.
I am aware that it has been previously proposed to provide means for promoting the water circulation in boilers. Thus, prior use has been made, for instance, of stationary or detachable saddle shaped chambers or sheathings which are provided with inlets and outlets and are applied saddlewise to the furnace fine so as to form more or less annular chambers in which the circulated water rapidly becomes heated. Such saddle-shaped chambers consist either of circular or more or less segmental frames which are connected at certain intervals by cross bars or straps or otherv means, and are adapted to fit on the flue in a plane at right angles thereto; or the chambers are made of U- or channel section corresponding to the chamber of the furnace and forming a water jacket which terminates above in a cylindrical part, the latter having a removable cover with a hole for the connection of tubes which, in turn, communicate between the dead water space and the steam generating space. In other devices of this kind, nozzles or mouth pieces are arranged at the top and bottom, respectively, of the saddleshaped casings, the top nozzles serving as outlets and the bottom nozzles as inlets for the circulating water. My invention is distinguished from such known devices in the arrangement of a series of angle irons which are adapted to be attached directly to the furnace, or which, if the furnaces are corrugated, are mounted on a plate fitting into the indents of the corrugations and attached thereto. A second plate mounted on the angle irons cooperates with the latter and the first plate to form a pocket or jacket with which the pipes are connected, the said pipes Specification. of letters Patent.

' being so fitted. thatthey are directed to any position in the boiler, thereby drawing the water from all parts thereof.
An embodiment of my invention. is illustrated in the accompanying drawings whereof Figure 1 is a fragmental elevation of a boiler having three furnaces; Fig. 2 is a fragmental sectional view; and Fig. 3 is a sectional view on an enlarged scale indicating a method of fitting the saddle piece to a corrugated furnace.
In.Fig. 1, three furnaces are indicated at 1, 1 and 1 but it is to be understood that the apparatus may be applied to any number of furnaces and of any make. All the furnaces are provided with saddle-pieces fitted with pipes which may be directed to any position in the boiler. There are numerous ways of constructing the saddlepieces, the one illustrated consisting of a11- gleirons 2 and 2, bent to conform with the furnaces and suitably riveted or bolted together to form a joint with a plate 3. An opening 4 is provided in the plate 3 at the crown of the furnace, to induce circulation, and a baffle plate 5 is introduced to prevent sediment from entering and settling in the pockets 6 formed by the saddle-piece, also to distribute the current. i
Fig. 3 shows the application of the saddlepiece to a corrugated furnace 1. Provision is here made of angle-irons 2 and 2*, as in the device hereinbefore described, the said angle-irons in this case, however, being scoured to the turned up edges of a plate 2 fitting into the indents of the corrugations and attached thereto. The plate mounted on the angle-irons thus forms, with the plate 2, the pocket or jacket 6, while pipes, (not shown), may be arranged and so housed within certain of the indents of the corrugations that they communicate at one end with the pockets, and at the other end with any part of the boiler.
I have described the invention as having the saddle boiler constructed in parts consisting of plates and angle-irons, but it will be understood that it may be cast integral and fitted to the furnace.
I claim A water circulator for corrugated boiler furnaces comprising a plate straddling the furnace and having portions conformably fitting in the spaces between the corrugations in said furnace, said plate being in said pocket; and pipes connected to the 10 formed with parallel upturned edges; a pair ends of said pocket. of angle-irons secured to said edges; aplate 'In testimony whereof, I aflix' mysignaconnecting said angle-irons and coiiperating ture, in' presence of twowitnesses.
