' To all whom t 'may concern.'
Be it known that. GEORGE EDWARD TANSLEY, a subject ofthe King of Great Britain7 residing at `Wakefield, Yorkshire, England, has invented certain new and useful Improvements in or Connected with Fuel Economizers vfor Steam Boilers, of which vthe following is a specilication.
This invention relates to that class of fuel economizer for steam boilers in which the tubes are arranged horizontally or approximately so andbuilt up in sections and the object kof this invention .is to provide means in connection with each section whereby each section is free `to expand and contract without undue friction and without affecting itsv neighbour, thus rendering the structure more flexible.
The invention will be clearly understood from the following description aided by the annexed drawings in which- Figure l is a sectional side elevation of a fuel economizer showing-the invention.
Figure 2 is a plan of one section of a fuel economizer embodying one section'of pipes. Y
Figure 3 is an elevation of a portion `of the back of a fuel economizer.
For the purpose of this vinvention and in simple form asis shown Ion the annexed drawings we construct a framework A preferably of iron and arrange same to support the headersB at each end of the tubes, the framework having ledges or supports C for carrying each section which is thereby independent and clear of the other sections except for the circulating bends D. ,j vThe vertical supports A between each group of sections are so designed as to allow of a minimum access of air whilst at the same time there is sufficient clearance for each section to contract or expand without undue friction and-without affecting its neighbours.
The headers B form the back and front walls of the economizer and are so ar-V ranged and carried by the frame that they just clear each other, and the very small space between` them is practically negligible, so that for all practical purposes the headers and frame form gas-tight walls or connections and no separate cover or casing is required. By mounting the headers on the ledges of the frame they can expand or contract independently of each other and without affecting the structure as a whole. The particular mounting on the frame also permits removal or withdrawal of any section for repairsk without dismantling the whole organization. The bendsk D are so designed that they will allow for a difference in expansion of about one-fourth of an inch between one section and an adjacent section. y
By this arrangement also any section of tubes may be removed and replaced without disturbing the adjacent sections.
The circulating bends D are of a flexible character so that no movement of one section is transmitted to another.v i
The vertical distances between the sets of ledges or supports in the framework may be of equal depth las usually required when vertical baffle plates are supplied or of greater depth at certain points as at E so as tofprovide a greater space between the lower and upper nests of multiple sections andv in these spaces horizontal baflles may be positioned j and we may provide soot doors F at these ledges or supports to enable cleaning to bev effected.
The water enters at the bottom row of tubes and is made to circulate backwards and forwards through each layer until it yreaches the top as is usual.
What I do claim as my invention and desire to 'secure by Letters Patent is A fuel economizer comprising a framework having ledges. a plurality of horizontal tubes arranged in separated sections with a similar number in each section and having headers connected to opposite ends thereof, the ledges of the framework supporting the headers of the sections of tubes `so that each section is supported clear of the next adjacent section andv is free to expand or contract independently of the next adjacent section, the headers forming the front and back walls of the economizer and arranged and carried bv the framework in such manner that they will just clear each other with a negligible space between them to lovide for the formation of gas-tight Wal s or connections, the seetons of tubes being connected by bends which allow for a difference of expansion between one section and an adjacent section.
In testimony whereof I have hereunto Set my hand in presence of two subscribing Wltnesses.
GEORGE EDWTARD TANSLEY. Vitnesses:
