Specification of Letters Patent.

Patented July 3, 1917.

To all whom it may concern:

Be it known that we, GARRETT E. MILLER, a citizen of the United States, residing at \Vest Nyack, Rockland county, State of New York, and JOHN A. BARNES, likewise a citizen of the United States, residing at West New Brighton, county of Richmond, State of New York, have invented certain new and useful Improvements in Superheaters, of which the following is a specification.

Our invention relates to superhe'aters, and especially to those applied to fire-tube boilers, and has reference more particularly to the means for securing the units or elements of the superheater to the header or collector. It has for its object the produc tion of such means which shall be readily applicable and detachable.

As is well known to those familiar with this art, the most approved way of attaching the units of these superheaters to their headers is in pairs by means of a clamp, the latter being drawn up toward the header by means of a single bolt through the middle of the clamp. The two ends of the unit pass through two holes at opposite ends of the clamp and their enlarged heads are securely held between the clamp and the header.

Such a clamp is slipped into place before the unit is finished and can of course not be removed without dismantling or destroying the unit, as it cannot be slipped 0E over the enlarged heads of the unit ends. The object of the present invention is to provide a clamp which can be applied or removed after the unit is completed and without disturbing it.

The invention will be readily understood from the following description which is to be read in connection with the accompanying drawing, in which Figure 1 shows the improved clamp in connection with the re lated parts of the superheater, portions being in section and parts broken away and omitted; Fig. 2 shows a perspective view of the clamp with the unit ends in place; Figs. 3, 3 and 3 represent respectively the three parts of this form of our invention, while in Figs. 4 and 5 are given two views of a.modification. A washer which may be used in connection with both forms of the device is and has a complementary shoulder.

illustrated in Fig. 6, a certain part being omitted to facilitate illustration. The scale of Figs. 1, 4, and 5 is smaller than that of the remaining figures.

To proceed now with a detailed descript1on of the invention. The header 1 has two chambers 2, and to it are secured the two unit ends 3 communicating with the two chambers 2 through the orifices at. This is effected by means of the bolt 7, whose head half 9 and the saddle-shaped member or yoke 9 is shown in section. The structure of these three constituent parts of the clamp will bereadily grasped from Figs. 3, 3 and 3 The parts 9 and 9 are identical in form and when placed in position clasp the two pipe ends 3, after which the yoke 9 is slipped into place from below.

The assembled parts then appear as in Fig. 2. The bolt 7 is then entered through the central opening formed by the two parts 9 and 9 and through the opening 14: in the yoke 9, and the nuts 8 and 8 threaded on the bolt, after which the clamp cannot come apart and may be tightened up.

In practice washers 6 are placed between the clamp and the enlarged unit heads, and a washer 10 between the nut S and the clamp.

The washers 6 may also be made so as to be readily placed on or taken OK the unit. A form making it possible to do this is shown in the several figures of the drawing and may be briefly described as follows. It consists of an inner ring and an outer ring. The latter, 11, has a bore large enough to pass over the enlarged unit heads 5, and a shoulder 13; while the inner ring is split Only one of the two halves of 'the inner ring is shown in Fig. 6, the other being just like the half 12 shown, and the entire structure can be readily understood from this figure. The bore formed by the two inner halves when they are in position is small enough so the assembled washer cannot pass over the enlarged unit heads. To put such a washer into position it is merely necessary to pass ring 13 over the unit head, put the two halves 12 of the inner ring into place and bring the assembled washer up against the head. To remove it a reverse order of procedure is followed.

,,This washer, it is to be understood, is not part of the present invention, and is not claimed except as combined with the other elements.

In Figs. 4 and 5 is illustrated a form of just described. All the connected parts are as in the former case, and the clamp is like the former in that it also has two symmetrical portions 9 and 9*. Instead of a single saddle shaped member or yoke 9 however there are two, 9 and 9 at bottom and top respectively. Their flanges 15 fit into corresponding grooves in members 9 and 9 The washers 6, in this case, rest partly on the yoke 9 and keep it in place. The mode of attachment or removal will be evident and need not be described in detail.

WVhile ordinarily the ends 3 will he ends of the same unit, it is evident that they may belong to different units; and similarly other variations of our invention or its application will suggest themselves. They are prising two symmetrical portions which, as-

sembled, present three circular openings, half of each opening being formed in each of the two symmetrical portions, and a saddle shaped member spanning the other two and having an opening in line with the central of the three first mentioned openings.

2. In a superheater, the combination with two unit ends, of a clamp comprising a portion divided longitudinally into halves, the two halves when in position clasping the two unit ends, and a saddle-shaped member spanning the two halves and preventing their separation.

3. In a superheater, the combination of a header; two unit ends; a clamp comprising a portion divided longitudinally into halves engaging said ends, and a saddle-shaped member engaging said halves and preventing their separation, and a bolt passing through said halves and said saddle-shaped member and fixed to the header and drawing the clamp toward the header.

In testimony whereof We have hereunto set our hands.
