IMPROVEMENT IN STEAM-BOILERS.

Specification forming part of Letters Patent No. 171,436, dated December 21, 187'5; application filed october 29, 1875.

To all whom t may concern Be it known that I, JOSEPH SHAcKLE'roN, of Buffalo, in the county of Erie and State of NewYork, have invented a new and useful Improvement in Steam -Boilers, which improvement is fully set forth in the following specitication, reference being had to the accompanying drawing, in which- Figure l represents a longitudinal vertical section. Fig. 2 is a transverse section.

Similar letters indicate corresponding parts.

This invention relates to an improvement in that class ot' steam-boilers in Vwhich a series of U-shaped pipes are secured with their open ends in a common uptake, said pipes extending in a horizontal direction over a tire-grate, so that when they are filled with water and exposed to the action ot' the tire, a rapid and abundant generation ot' steam is effected.

My present improvement consists in combining an l' -shaped partition or screen with the uptake, and with the U-shaped water-pipes extending from the same, in such a manner that a complete circulation ot' water through the U-shaped pipes is effected, and the escape of solid Water with the steam is prevented.

In the drawing, the letter A designates the uptake ot' my steam-boiler, from which extend a series of U-shaped pipes, B, which are ot'V gradually-increasing length, so that each suc-- ceeding one will entirely embrace those preceding. Each of these U-shaped pipes is `secured in the uptake with its open ends, and all said pipes extend over the tire-grate O, which is situated in the lower part of the furnace-wall Which surrounds my boiler. In' the interior of the uptake is secured an |'shaped partition or screen, D, which separates the lower apertures a b c of the U-shaped pipes from their upper apertures a b' c.

It' the boiler is filled with water, and a lire is raised on the grate C, the water contained in the lower branches of the U-shaped pipes is driven out above, and the water thus displaced is immediately replaced by water from the uptake, and by these means a complete disengages from the water, and which accummulatcs in the upper portion of the uptake, is free from solid particles of water.

It is obvious that the num ber ot' U-shaped pipes emanating from the uptake A can be increased to any desired extent.

In the example represented by the drawing I have shown four uptakes, A, which are connected at the bottom to a common horizontal drum, D, and at the top to a common steamdome, E.

In each ot' the uptakes are secured' three sets of U-shaped pipes, B, which may be staggered, as indicated in Fig. 2. By this arrangement a boiler ot any desired capacity can be constructed, and steam can be generated with rapidity, safety, and economy.

The U-shaped pipes B are secured in the uptake, each with its open ends at different levels, one ofthe said ends ot' each U-shaped pipe being situated above the other end, so that by the difference ot' the temperature in the two horizontal branches ot' each pipe combined with the action ot" the diaphragm, a constant circulation ot' the Water through said U-shaped pipes is insured.

What I 'claim as new, and desire to secure by Letters Patent, is'- The combination ofa series of return-tubes, having ascending branches, with an uptake and a defiector, D, the upper ends ot' all the said return-tubes being situated above, and their lower ends below, the deiector, as and for the object specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 18th day of September, 1875.
