STEAM- GENERATOR.

Specification of Letters Patent.

Patented Nov. 9. 1909.

Application filed October 29, 1908. Serial No. 460,017.

To all whom it may concern:

Be it known that 1, Flint) N. TILTON, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Stea1nGenerator, of which the following is a full, clear, and exact description.

The invention relates to tubular boilers having pipe coils connected in series, to form one continuous passage for the water and steam, and its object is to provide a new and improved steam generator having no sharp bends and but few and strai ht joints between the pipe coils, the latter eing arranged to permit ready assembling and to all liw convenient access to any one of the C01 s.

The invention consists of novel features and parts and combinations of the same,

which will be'more fully described hereinafter and then pointed out in the claims.

A practical embodimeht of the invention is represented in the accompanying draw ings' forming a part of this specification, in which similar characters of reference 1nd1- cute corres ondin arts in all the views.

Figure 1 is a plan view of the improvement, the inclosing shell being shown in section; Fig. 2 is a side elevation of the same, the shell and burner being shown in section; and Fig. 3 is a side elevation of one of the spacing blocks.

The plurality of connected pipe coils shown in the drawings, consists of a top pipe coil A, a bottom pipe coil 13 and a desired number of intermediate coils C, arranged one above the other and all inclosed in a shell for the passage of the heat from a suitable burner "E, the lowermost coil being seated on the said bottom D The coils are held spaced apart by placing blocks F, having notches at the top and bottom to fit the pipes, and the coils are bound together by top and bottom bars G and G connected with each other outside of the coils by bolts G as plainly indicated in Fig. 2.

The water inlet A for the inner end of the uppermost coil A extends between the top coil A "and the nextfollowing coil C below, and the outer end of the top coil A is connected by the connection A with the outer end of the next coil C below, but the intermediate coils C all connect at their in- 1 the coi nercnds by connections C with the outer end of the next following intermediate O below. the connection extending over the top of the corresponding intermediate coil (1. and then down the outside thereof, to conmeet with the outer end of the next following intermediate coil G below. In a like manner the lowermost intermediate coil C has its inner end connected by the connection C with the outer end of the bottom coil B, the connection C extending on top of the lowermost intermediate coil C, and over the outer end therof, to then merge into the outer end of the bottom coil B. The inner end of the'botttom coil B terminates in the steam outlet B which passes over the top of this bottom coil B, past the outside thereof, to then merge into a pipe B rising within the shell I) and passing through the top thereof to connect with the motor or other device in which the steam is to be utilized. I l

The couplings H, between the several coils are in the straight portions, as plainly indicated in Figs. 1 and 2, so that all sharp bends are prevented and the joints are but few, that is, not more than the number of coils employed.

By the arrangement desired the coils can be readily assembled and connected with each other, and convenient access can be had to any one of the coils whenever it is necessaryto repair or remove any one of the coils.

It is evident that the water flowing through the coils from the top downward encounters very little resistance as sharp bonds are avoided, and consctpicntly a large I) having an openingl) at the bottom 1) amount of water can he quickly converted into steam. carried ott' trom the lowermost coil'locatcd nearest the source of heat.

,I-laving' thus described my invention, I

claun as new and desire to secure by Letters Patent:

1. t steam generator, comprising n cylindrical shell having an opening in the bottom for the passage of heat, a lurality of pipe coils arranged one above ti e other in said shell, the lowermost coil being seated on the bottom of. the shell, the said pipe coils being connected in series, the connections extending between adjacent pipe coils, radiall arran ed blocks interposed between is to hold the same spaced apart, the

said blocks having notches at the top and bottom to fit the pipes, oppositely arranged lic- ' tween the coils, the said blocks having the outer end of the said top pipe coil and 1 v the outer end of the uppermost intermediate I coil andthe outer end of the gether.
