To all whom it may concern.' l*

Be it known that I, HOWARD T. HALLO- WELL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Im rovements in Shaft-Hangers, of which the flcillowing is a s ecification.

My 'invention relates to s aft supporting structures; and the object of my invention is to provide hanger structures of substantially the same type illustrated in the stent of Harald'fF. Gade, No.1,165,332,rfitte|d"1)e` eember 21, 1915, in'which are shown shaft hangers `constructed of commerciaalfrolled metal sections.

i IIn thev formof structure shown in Fig. 1, I have illustrated a. shaft hanger havin side supporting members made from a: V-'s aped metal section, lwhich vma be sheet 'metal pressed ':intpY the l desired -shaped cross section 1or aromiriercilfiangle section, and each of these side` supporting memberswis bent to pr'ovfidemflegiportion 1;v n journal-"box(sup-` porting portion 2, `and affoot f3, integral with said leg portion. The upper endof the side supporting members from whichl the feet ofthe han er' legsareformed is rein forced by Adoubling the metal composing 'the same, and -the shape of thsai'd upper end of the blank of the side supportin member is shown in Fig. 2. The legs are s aped in substantially the same manner as in' the application before referred to; the metal being gradually flattened from the point :c and forming the Ibroad supporting feet 3 at the ends thereof.

In manufacturing legs provided with the reinforced feet, the narrow tongue 1 is bent back upon the major portion of the leg, and

the edges of the latter for a certain length are bent up to forni flanges 1h to enga e said tongue, Which'is then secured to the ei by rivets 1. A bolt aperture 3 is forme 1n the doubled end of the leg, and then it is bent to the shape shown in Fig. 1, forming a foot. In somefinstances, the central portion of .the foot adjacent the 'bolt aperture may b depressed as at 3b for added strength.

`In the form of hanger shownin Fig. 1, I employ a special forni of connecting o r bracing4 member 5 for the legs, which is duplex in character; the halves beingdivided on a vertical line. The blank` forforming one-half of said bracing member is shaped as shown in Fig. 11, and this is pressed up into the shape shown inthe side elevation, Fig. 12, providing-.earsifi whiclrare;v disposed at anangle with respect lto the-longitudinal portion of said connecting or bracing member, and these ears are secured/to thefhanger leg by rivets 7. 4.'ilo avoid anydanger of the metal vof the leg spreading at this point, I

- as indicated at 16, to form hanger.-

inay provide retaining means in the form of clips 8, as. illustrated in Figs. 13.and 14, which are held to thefhanger legs and connectingand bracing member by the rivets 'I he portion of the blank.- forming the horlzontal walls of the connecting or `bracing member` is notched at 9,,andwhen thetwo halves` of the, braein imember are,` brought together, these notc es rovide apertures for the passage of tveti ,positioning bolts 10, shown by dotted-linea.' 'when itis desired to usethe latter,"` i 11i The, lower portions of the shaft hanger legs areishaped as shown'in Fig. 6,'iand'the bottom ends aresquared -as indicated at`11. Connecting the' squared ends of the legs is a `pressed sheet metal cradle structure 12 having embracing end walls 1.3 to engage the squared ends `11 of the legs, and this cradle structure is secured to the leas by bolts 14:.

This cradle structure is provided with ends 15 continuous with the bottom thereof, which engage the' outer wallsofifthe legs, and this bottom is preferably socketed atithe center, seats for nuts 17 and 18,and apertured for the passage of the lower, vertical positioning bolt, when the latter-:is employed. i

Figs. 7, 8 and 9, illustrate various forms or sections of commercial metal orV sheet metal which mayvbe employed forthe legs of the ith this form of hanger, I also preferably provide a bracin member 2() connecting the legs in substantially the plane of the feet, which may be secured to the legs by rivets 21.

In Fig. 15, I have shown a hanger structure substantially like that shown in Fig. 1. excepting certain modifications or changes in the shape of the legs. The lower ends of the legs below the journal-box supporting portion are reduced in size and shaped as at 11n for the reception of a lower connecting member 12, of the same contour as the legs, which may be secured to said legs by bolts and nuts 22 and 22; filler pieces or blocks 23 being employed to overlie the outer wall of the cradle structure. This forni of hanger is provided with the usual adjustable position' bolts 24 fora journal-box; with a cross piece or bracing member 5 of a type hereinafter described, and with a bracing 'f member 20, connecting the legs in the plane of the feet.

In Fig., 16, I have shown another form of hanger embodying my invention in which a J-shaped support for the journal-box is provided. In this instanee, the J-shaped support and one leg are formed from a single continuous piece While the other leg has a horizontal portion 5" i crossing `above. the 'ournal-box and joined to the continuous leg l) rivets 25. In such structure; I ma pr vide upper and lower positioning` bo ts 10, as indicated by the dotted broken lines, for the ,journal-box, as well .as the horizontally disposed positioning bolts 24:. This hanger is also provided with a bracing member 20 connecting the legs'in ,the plane of the feet.

InlFig. 17, I have shownia shape or `form of 'blank from which the formof bracing and. connecting member shown 1in use in Eigs.y 15 and 16, and'within the scope of my inventionmay befmade. Tliis blank is recessed at 26 on both sides, and slit-at. a, and b theslits bbeingat right angles=to the slits a. It is then pressedintoptheshape shown in Figa 18, 19 ,and-,20,.providing .a series of ears tif-whereby. itimaybe riveted to the hanger,i and ris apertured -at 9*1 for the passage of a positioning bolt, such asilO. y

. `IIL-Fig. 21, I have shown a sectional plan viewV of the legs of a type of hanger such for Ainstance as 4illustrated in Figs. 1 and 15, in which the legs are made from a metal section fsuch as Shown `in Fig. 9. These legs are spaced apart and secured together by a connecting member 5" whichis also duplex in character; that is to say, it is made of upper and lower members each of the saine shape; the complete structure being .shown in elevation in Fig. 23, and in cross section on a larger scale in Fig. 24, such View being on the line 24-24, Fig. 23. Fig. 22 shows theblank rornwhich the sections of this bracing or connecting member are made.

Fig. 25 shows a modified construction in which the walls of the half sections 5c instead of abutting each other on a median line, are lengthened and pass within each other on opposite sides. These forms of bracing or connecting members are provided with ears 6C. which are riveted to the hanger legs.

In Fig. 26, I have shown the construction of the lower en d of the hanger leg shown in Fig. 21, to which a lower connecting crossmember having ends shaped to member or cradle structure V12" is connected; Fig. 27 beinga sectional vievv on the line 27-27, Fig. 2,6.
