TUB'E-S'HEET FOR STEAM-BOILERS, 80C.
^ SPECIFICATION forming part of Letters Patent No. 352,380, dated November 9, 1-886.
Application tiled August 23, 1886A Serial No. 211,690. (No model.)
To @ZZ whom it may concern:
Be it known that l, HENRY WARDEN, a citizen ofthe United States, residing in Philadelphia, Pennsylvania, have invented certain Iniprovements in TubeSheets for Steam-Boilers, Feed-Water Heaters, Src., of which the following is a specification.
One object of my invention is to so construct a tubesheet for steam-generators as to prevent straining ot' the sheet or impairment of the joints ofthe tubes therewith, owing to expansion and contraction ofsaid tubes, a further object being to so stiften the tube-sheetthat a less number of internal stays than usualwill be required to retain the same.
In the accompanying drawings, Figure l is an end View of a boiler, feed-water heater, or analogous structure having a tube-sheet constructed in accordance with my invention; Fig. 2, a sectional view on the line l 2 of the end portion ofthe structure, and Figs. 3 and 4views-illustrating modifications of the invention.
A represents part of the shell ot' a boiler, feed-water heater, or other structurein which my improved tubesheet is used, this structure in the present instance being of cylindrical form, although it may be of different shape vwithout departing from my invention.
B are the tubes, the ends of which are secured in the tube-sheet D by expanding them into openings formed in said sheet in the usual manner; but in carrying out my invention I form in the tube-sheet around one or' more of the tube-openings, or around one or more groups of openings, a groove or corrugation, a, outside of which is an'elastic portion, b, the preferable plan being to form a corrugation around each tube-opening and as close as practicable to said opening. This corrugation serves to stiften the tube-sheet at andnear each tube, so that when there is longitudinal movement of the end ofthe tube,due
- to eipansion and contraction ofthe said tube,
that portion of the tube-sheet immediat-ely surrounding the tube moves with the end of the latter, the movement being permitted owing to the elastic portion b around each corrugation o, this portion preferably consisting of a flat space of sufficient area to insure the requisitel elasticity. Each tube is thus free to eX- .pand or contract independently of the other gle tube or group of tubes alone may have the circumscribing corrugation and outer elastic portion. The tube-sheet has in the present instance upper and lower man-holes, F and G, andin order to stiften the sheet where these man-holes are formed each of said man-holes is surrounded by a corrugation, d.
In that portion of the tube-sheet above the tubes I form a series of corrugations, f,which serve to impart such stiffnessto this portion of the sheet that the number of internal stays necessary in the structure may be very mate-l rially reduced.
I claim as my invention- 1. Atube-sheet one or'more of the openings of which has a circumscribing corrugation,with elastic portion beyond the same, all substantially as specified.
2. A tube-sheet the tube-carrying portion The tubes may, however, be divided of which comprisesa number of divisions, each strain due to the uneven expansion and contraction of the tubes, all substantially asspecifled.
5. A tube-sheet having tube-openings and one or more man-hole openings with circumscri'bing corrugation, all substantially as specifled.
6. A tubesheet having oneor more tubeopenings or tube-spaces with circumscribing IOO In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
HENRY WARDEN.

THOMAS M. KELLY, HARRY SMITH.
