HEADER FOR SECTIONAL STEAM-BOILERS SPECIFICATION forming part of Letters Patent No. 682,989, dated September 17, 190 1. Application filed January 2, 1901. Serial No. 41,890. (No model.)
To zoZZ whom it may concern.-
Be it known that I, CAMPBELL I. HIGGINS, a citizen of the United States, residing at B0- selle,in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Headers for Sectional Steam- Generators, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to sectional steamboilers in which a series of water-tubes are connected at their opposite ends to headers of serpentine or corrugated shape, which are arranged in line to form a group. The watertubes are generally used in an inclined position and the connected headers either placed vertically or at right angles with the inclined tubes. The size of these headers is limited for convenience of manufacture, transportation, and use, varying in length in some instances, but of a predetermined width sufficient to insert at each offset or corrugation either a single tube of about four inches in diameter or a cluster of tubes of about two inches in diameter, leaving sufficient space surrounding the tubes for the passage of the products of combustion and clearance to avoid the accumulation of ashes and soot between them. In the insertion of the smaller tubes a cluster of three and four tubes have heretofore been placed at each offset or corrugation of the header; but the shape of the corrugation in the header prohibits the possibility of locating the tubes to obtain a'desired relative arrangementand form the handhole aperture in the face of the header opposite each cluster of tubes, so that free and unobstructed access could be had to each and all of the tubes forming the cluster for purposes of inspection, cleaning, removal, or replacing and leave sufficient margin on the face of the headers at the sides of the aperture to form a bearing for its plate or cover.
The object of the present invention is to construct aserpentine header with such shape of corrugations as will permit the insertion of a cluster of tubes of standard diameter at each corrugation or offset in a relative position to maintain their Vertical staggered arrangement and also to maintain a proper distribution of space between and around the same and also to provide a hand-hole in size to obtain free and direct access to all the tubes, leaving sufficient margin on the face of the headers to form a bearing for the handhole cover without departing from the size ofof the cluster, and with sufficient surface on the face of the header at the sides of the hand hole to form a bearing for the plate or cover.
In the accompanying drawings, Figure 1 is a front or face view of a header embodying the new form of corrugation with the handhole covers removed and showing an end view of the disposition of the Water-tubes; Fig. 2, a side elevation of the header, showing an end portion of the connected water-tubes; and Fig. 3, a cross-sectional view of the whole group of tubes, showing a vertical staggered arrangement of the tubes and a line of horizontal space between each vertical row through out the entire width of the group.
a is the header, and b the connected watertubes. The tubes 1) are placed in clusters of three or four, as shown, and each corrugation or offset 0 is shaped to make room for such position of the tubes as will provide sufficient space surrounding the cluster and between the tubes and around the hand-hole aperture on the face of the header to form a bearing for its plate or cover. The form of the corrugations or offsets shown permits the use of a cluster of the greatest number of tubes of standard diameter possible to preserve a desired relative staggered arrangement vertically and obtain a horizontal line of space between each cluster and each vertical row of the tubes of the cluster extending throughout the whole width of the group, whereby a better inspection can be made among the tubes and cleaning devices can be more conveniently introduced and effectually operated. This form of corrugation or offset of the header also permits the construction of the hand-hole aperture in the face of the header opposite each cluster of such shape and size to obtain direct and free access to each tube of the cluster and to provide sufficient hearing on the sides of the aperture for the cover of the aperture.
What I claim, and desire to secure by Letters Patent, is
A corrugated header for sectional steamgenerators having each corrugation constructed with flattened sides to produce a parallelogrammic form, so that a cluster of water-tubes of maximum number and standard diameter csaese may be connected at each corrugation and provide for: sufiicient space between and surrounding said tubes: a hand hole aperture opposite the end of each cluster of tubes, through which full access can be had to each tube of the cluster: and, a seat or bearing surrounding the aperture for a cover or plate, as set forth. 7
In testimony whereof I afiix my signature in presence of two witnesses.
CAMPBELL P. HIGGINS.
