eeaosa Specification of Letters Patent.
Patented Nov. 1d, 1916.
Application filed February 24, 1915. Serial N 0. 10,230.
To all whom it may concern Be 1t known that L NOAH B. SHEPARD, a
citizen of the United States, residing at Cypress Inn, in the county of lVayne and State of Tennessee, have invented certain new and useful Improvements in Boiler-Heads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled I in the art to which it appertains to make and use the same.
The invention relates to improvements in boiler heads. 7
The object of the present invention is to provide a simple, practical" and eilicient boiler head of strong and durable construction adapted to obviate the disadvantages and troubles resulting from the burning out of the ends of boiler tubes of the ordinary construction and to provide an improved construction in which the water will be permitted to circulate entirely around the ends of the boiler tubes whereby the latter are maintained su'liiciently cool to prevent them from burning out.
lVith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the apcompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the ad vantages of the invention.
Figure 1 is a horizontal sectional view of one end of a boiler provided with a boiler head constructed in accordance with this invention, Fig. 2 is an elevation of the boiler head viewed from the inner side, and Fig. 3 is an enlarged detail sectional view illustrating the construction of the grooves into which the ends of the boiler tubes are expanded.
Like numerals of reference designate corresponding parts in all the figures of the drawing.
In the accompanying drawing in which is illustrated the preferred embodiment of the invention 1 designates an outside boiler head united at its periphery to the wall 2 of the body portion of the boiler in the usual manner. This outside boiler head which has openings 8 corresponding with the boiler tubes l is connected with an inner boiler head or partition wall 5 by short integral horizontal tubular extensions 6 but the latter may be arranged at an inclination or in any other position to suit the disposition of the boiler tubes. The inside boiler head 5, the connecting tube 6 and the outside boiler head 1 are preferably cast in a single piece, the tubular portion being of suflicient size to connect the two boiler heads rigidly together.
The inner boiler head 5,'which is designed v to extend upward only as far as the boiler tubes, terminates at its side edges short of the walls of the boiler and is arranged in spaced relation with the same to permit the water to pass around the side edges of the inner head 5 to the space between the inner and outer headsand the said inner head 5 is also provided with a plurality of openings 7 for the passage of water to the intervening space between the boiler heads. Any number of these water passages or openings 7 may be employed and in practice the inside head will be provided with as many as may be conveniently formed therein without weakening the structure. The inside boiler head is also provided with openings 8 corresponding with the bores or openings of the tubular extensions or connecting portions 6 and receiving the adjacent ends 9 of the boiler tubes l. The ends 9 of the boiler tubes 4 are expanded by suitable tools into grooves 10 of annular shape preferably formed in the inner head but the grooves may be provided at any other desired point and they efi'ectively prevent the boiler tubes from pulling out of the openings of the inside head. The inside boiler tube supporting head 5 holds the ends of the boiler tubes in spaced relation with the outside head, and as the water is permitted to circulate entirely around the ends of the boiler tubes the latter are effectively prevented from burning out. The short tubes 6 or tubular connecting portions and the boiler tubes 4 form passages for the products of combustion in the usual manner and the improved boiler head is designed for use in connection with various types of boilers of this class.
What is claimed is 1. A device of the class described includ ing an outside boiler head designed to be united at its periphery with the walls of the boiler and provided with openings, an inside boiler head or wall spaced from the outside boiler head and also from the walls of the boiler and located within the same, said inside boiler head or wall being provided with openings for the reception of boiler tubes and short tubular portions connecting the inside and outside boiler heads coinciding with the said openings.
2. The combination with the walls of a boiler of an outside head connected at its periphery to the said walls and provided with openings, an inside head or wall located within the boiler and spaced from the walls thereof and also from the outside head, said inside head or wall being provided with openings for the reception of the ends of boiler tubes, and short tubular portions formed integral with the inside and outside heads and coinciding with the said openings.
3. The combination with the walls of a boiler, of an outside boiler head united at its periphery with the said walls and provided with openings, an inside boiler head provided with openings for the reception of the ends of boiler tubes and having interiorly arranged grooves into which the tubes are expanded, and tubular extensions or members connecting the inside and outside heads and coinciding with the said openings.
4:. The combination with a boiler, of an outside head united at its periphery with the walls of the boiler and provided with openings, an inside head spaced from the walls of the boiler and also from the outside head and provided with boiler tube openings and having other openings for the passage of the water, and tubular portions connecting the inside and outside heads and coinciding with the openings of the outside head and with the boiler tube openings of the inside head.
In testimony whereof I aflix my signature in presence of two witnesses.
