narran STATES PATENT OFFICE RALPH N. ROBERTSON, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR, BY MESNE AS- SIGNMENTS, TO BLAW-*KNOX COMPANY," OF BLAWNOX, PENNSYLVANIA, A COIR- roRATIoN, or' NEW JERSEY v HANGER Y Application sied May 27,

This invention relates to ,means for susaendino an Jaratus and it relates articu` larly to hangers for suspending apparatus which are to be installed in boilers or the like. When such apparatus is connected to pipes, or portions of the boiler,fsnch as the not properly register with the apparatusso as to conveniently make the conn-ection required. Although my invention applies to various other apparatus anduses, yet. for the purpose of this disclosure, I have `illus- `^-15 trated and described a steam separator which is mounted in a boiler and whichk is supported by a hanger. K

Of the accompanying drawings, Fig. .1 is an end view of a steam separator supported, in a boiler, by hanger which embodies the features of my invention; Fig. 2 is a fractional plan view of the separator and a hanger; Fig. 3 is an enlarged plan view of the hanger alone: Fig. 4 is a side elevation of .the hanger; Fig. 5 is an elevation of a modified form of hanger; and Fig. 6 is a side elevation of the same.

In mounting steam separators in boilers it is usually necessary to connect the separaperhaps to drain pipes and the like; so that the separator, in making these connections, becomes substantially fixe-d in position and can not conveniently be shifted horizontally to register withany fixed suspending means. Even when the separator consists oi severalk sections, some one of the sections is connected to the piping and none of the sections can. be conveniently shifted. To obviatefthe necessity of the points ofvconnection of the seL arator registering exactly with a certain fixed point of connectionto the boiler or the hang er, I provide thefmeans illustrated.V These comprise a hanger 10, which is adapted to be slidably connected to the separator-'11 and to be fixed. in any suitable manner. tothe wall of the boiler 12. The hanger may be arranged to slidably connect with the upper surface of the separator in any suitable manner, such as by means ot' flanges 13 which tor to the steam nozzle of the boiler. and

project outand under the elongated fianges,

14. These flanges are fixed to bars 20 which extend as'f'ar as may be Vdesired along the upper surfaceof' the separator. I prefer to have these bars extend from one endof yeach section of the separator to the other.. and they may beiXed to the casing by ywelding orby any suitable means. e.

The hanger israngularly shaped, having the' vertical standard 15, the horizontal arm 16 for connecting to the stud 17, which is fixed to theV boiler. and the flange 13./the ends of which project outwardly under the fianges 14. In the arm 16 is an elongated slot 18. The distance between' the outer ends of the flange-13 is somewhat less than the distance between the two upright portions of the straps 20, and the ends 21 are rounded someF what, so that the arm 16 can be turnedamaterial distance to one side or the other in Vorder to properly register with the stud 17 necessary, and the arm 16 can then be turned toy one side or, the other, if necessary, so that the slot'18 will be in a position to receive the stud 17. This stud can be as long as maybe desired and the arm 16 can be supported by means of the nuts 21 at any desired elevation.

In order that the hanger may more rigidly hold the separator-section in place, provision may beA made for locking it to the separator when the hanger is screwed tightly onto the stud. By Ymaking the width of the angular flanges 13 greater thanthe height of the slot formed by the y,flanges 14 and the top plate ofthe separator 11 (Fig. L1), the hanger can the flanges 13 in the slot. Then, when in position. as' the nut-s 21 are screwed against the hanger, the arm 16 will be forced horizontal# ly. the slot 18 allowingV it to move relative to the stud 17. This will bind or lock the anges 13 in place between the flanges 14' and the separator 11. f f f v It is to be understood that several hangers may be applied tothe same section, for instance one at each end of the section, and that modification may be made in the shape of the hanger or the straps 20, without departing from the spirit'of my invention.

Fig. 5 shows a modification ofV a hanger in which the flanges pass inwardly Jfrom depending arms 26 on each side of the T- shaped beam 27, which is fixed in any suitable l manner to the top of the section. In this case the hanger may be shifted along the T beam and, by spacing the members 26 apart somewhat more than the width of the top of the beam, the arm 28 can be turned to one n side or the other as in case of the hanger of Figs. l to 4. `And by properly shaping the portions of the hanger and beam which eoact, the hanger can be locked inposition with reference to the separator section when bolted tothe wall of the boiler.

I claim as my invention:

l. Suspending means comprising a pair of spaced parallel straps fixed edgewise to a body to be supported, an elongated V flange fixed to the outer edge of each strap and projecting towards the other strap, thus forming a slot with over-hanging outer edges, a hanger one end of which is positioned in said slot, said end'having fianges extending out-4 wardly under said elongated lianges, the vertical height of said iianges when said hanger extends outwardly in one direction being less than the depth of the slot beneath said elongated flanges, but becoming equal to said ldepth and binding in said slot when said hanger extends outwardly in another direcv tion.

2'. Suspending means as claimed vin claim l in which the other end of said hanger has an angularly proJecting arm having a slot therethrough.

.BKSuspe'nding means comprising a strap adapted to have one edge fixed to the side of a member to be suspended, an elongated 'fiange projecting angularly from and parallel with but spaced from said side, "a hanger `adapted to be supported by one end, the

other end of said hanger having a flange adapted to be passed between said elongated flange and said side, and being wider lthan thev distance between said elongated iiange and the side, whereby said two flanges automatically lock together by pressing against leach other when said hanger is tilted to eX- tend substantially vat right angles from said elongated flange.

4. Suspending means adapted to suspend one member from another, said means comv prisin-g a strap adapted to have one edge fixed to the side of one of said members, an elongated flange proieeting angularly froml said Vstrap Vand parallel with but spaced from said side, a hanger adapted to be attached to the other member by one end, and the other end of the hanger having a flange adapted to be passed between said elongated flange and said side and being wider than the distance between said elongated flange and the side, so that said two flanges lock together by pressing against each other when said hanger extends substantially perpendicular to said elongated flange.

5. A suspending member and a member to be suspended, one of said members having a slot forming means and the othei` member having a flange adapted to pass into said slot to suspend the member to be suspended, the vertical. dimension of said flange when the member is normally suspended being sufficiently greater than the vertical width of said slot to bind said Aflange in said slot.

6. A suspending member and a member to be suspended as claimed in claim 5, the vertical dimension of the flange, however, being less than the vertical width of the slot when the two members are tilted somewhat from the normal suspending positions.
