To all 'whom ?It 'may camera:

Be it known that I, WILLIAM F. SGHANZ- LIN, a citizen of the United States, and a resident of Lima, in the county of Allen and State of Ohio, have invented a new and Im proved Steam-Boiler, of which the following is a full, clear, and exact description.

T he present invention relates to new and useful improvements in steam boilers, and

pertains more particularly to that class of boilers commonly known as the water-tube type.

The primary object of the present invention is to construct a water-tube boiler in such a manner that the water tubes are subjected to the greatest possible amount of heat generated by the furnace.

A further object of the invention is to construct a water-tube boiler in such a manner that the cross-over tubes generally employed in devices of this character areentirely eliminated, thus doing away with dead airspace, and the consequent loss of heat.

A still further object of the invention is to provide a plurality of upper drums and means for securing the drums together.

With the above and other objects in View, reference is had to the accompanying drawin 's, in which- 4 *igure 1 is a Vertical sectional view of a steam boiler furnace, the water tubes and drums being shown in end elevaton;

Fig. 2 is a detail sectional view of a portion of one of the upper drums;

Fig. 3 is a detail sectional View takenlon the line 3--3 of Fig. 2;

Fig. t is a detail' perspeetive sectional view ot the means employed for securing the upper drums together. i

Beferring more particularly to the drawings, the reference character 5 designates the furnace housing, and 6 represents the grate bars thereof. The reference character 7 designates the bridge wall, and mounted to the rear of said bridge wall 7, is a large lower water drum 8, which extends across the 'u'nace housing 5. This drum 8 is provided with an inlet pipe 9, by means of which the water is supplied thereto, said drum being further provided with a cleanout opening 10, as shown in Fig. l.

Mounted in the upper end of the furnace housing 5, are two drums 12, and connecting each of said drums 12 with its respective side of the longitudinal aXis of the drum 8, are water tubes 13. These water tubes are connected to the upper drums 12 in any desired manner, and are arranged as shown in Fig. l, m two sets, one set beng Secured to the one side of the longitudinal axs of the drum 8, the other Set being secured to the opposte side of the longitudinal axis of said drum.

lteferring to Figs. 3 and 4, the means by which the two upper drums 12 are Secured together will be seen to comprise a metallic body portion 15, upon the opposite edges 16 of which are formed oppositely disposed fianges 17, which are provided with a pluralty of spaced openings 18, the purpose of which will be hereinafter described. The body portion'l is provided with a plurality of elongated openings 19, which pass entirely therethrough, and the drums 12 on their opposed faces are likewise provided with openings 20 adapted to register with the openings 19 in the body portion 15 heretofore mentioned. The fianges 17 are so shaped that they conform to the general contour of the drums 12, and as shown in Fig.

3, the securing means s placed between the drums 12, with the fianges 17 in contact with the outer surface of each of the drums.

The body portion 15 is then secured in place by means of rivets or the like 21, which pass through openings in the drums 12 at points where they will register with the openings 18 and the fianges 17. By this Construction, it is apparent that the two drums 12 may be Secured together in rigid relation to each other, and, at the same time, communication between the drums is established through the elongated openings 19. Leading from each of the drums 12, is a discharge pipe 22, the ends of said discharge pipe 22 being connected by means of a T- coupling 23, which in turn is connected to the main discharge pipe 23, by means of which the steam as generated is carried ofl'.

By this construction, it will be seen that the lower drum 8 is at all times in communication. with the upper drums 12, through the medium of the circulating water tubes 13, and that the drums 12 are in communication with each other as hereinbefore stated, thus permitting of a complete circulation of the water taking place under the influence of the heat of` the furnace.

I claim: i

1. A water tube boiler comprising a lower drum, a plurality of upper drums arranged in spaced relation to each other, a plurality of water tubes eonnecting the lower drum With the upper drums, and means for securing the upper drums together and establishing communication therebetween, said securing means comprsng a bar, the body of which is provided With a phrality of spaced -perforations,eaoh of the side edges of said bar being formed With two outwardly fiared spaced i fianges perforated to provide for their attachment to their respective drums.

2.' In combination with a plurality of Water oontainers adapted to be Secured together in communication With each other, bar, the body portion of which is provided With perforations in spaced relation to each other, said bar being formed on its side edges With outwardly fiared fianges perforated to receive the secnrin;` means by which' the containers and the bar are Secured together to provide a unitary structure.
