Application filed March 19, 1912.

Bumnnr, Philadel- Letters Patent of the United States, No;

699,943, granted to me under date of May 13th. 1902. in that the main members may be conveniently constructed from commercial sections of i'olled metal, the preferred forms being angle-irons of L-shape in cross section.

By my present invention 1 am enabled to construct from relatively light metal, a shaft hanger having great stability and rigidity, possessing the required strength at certain critical regions, and having a structural sym metrv which is desirable.

ln the accompanying drawings, Figure 1, represents a side elevation of a shaft hanger embodying my improvements, the device. being, (for convenience of illustration upon the sheet), represented in an inverted position from that in which it is usually employed. Fig. 11. is a front or edge elevation thereof. Fig. 111. is a vertical longitudinal section on the lines 111, 111, of Fig. I. Fig. IV. is an inverted plan view of the hanger. Fig. V. is a transverse section on the line VIV, of Fig. 1. Figs. VI, and VII, are details of portions of the removable cross bar, or yoke of the hanger. Fig. VIlLis a partial sectional view of the foot of the hanger on the lines VIII, VH1, of Fig. I. Fig. 1X, is a view in perspective of one of the gusset plates which constitute elements of the foot.

In its general structure, the hanger comprises the foot 1, the arms 2, and 3, the removable voke a, and the fixed cross-brace 5. these main elements having the general structural, relations and purposes characteristic of old and well known types of shaft hangers, and being provided with the usual box-supporting screws 6, 7, 8, and 9, to adiustablv hold the journal box 10. for a shaft 11. The arms are counterparts of one another, and therefore a detailed description of the arm 2, will sufiice. It comprises a pair of angle irons of L-shaped cross sec- Specification of Letters Patent.

'tion, the flanges of one member of the pair being indicated at 12, and 14, and those of the other member of the pair at 13, and 15. The flanges l i, and 15, are arranged in comparatively close proximity to one another and in parallel relation, throughout the greater portion of their length, but diverge for some distance as they approach the foot, and then resume their parallel relation at the region of attachment thereto. as iIlCllCt ted at 16, and 1'7, in Fig. H. it will be noted that the proximate flanges of the angle irons are situated at the outer side or edge of the arm, the flanges 12, and 13, (which may be said to constitute the broad. face of the arm) being upon the inner side, or nearest to the journal box. In this respect, (though not in the further details of the arms) the arrangement of the angle irons is similar to that of my former patent above mentioned, and possesses structural advantages over those forms of shaft hangers in which the broader face of the arms is situated at the outside. The flanges 1 1:, and 15, are spaced near the middle portion of their length, by the interposed plates 50, and 51, of the cross-brace 5, which will be described later on, and, at the ex tremity remote from the foot, by the distance piece 20. It will be noted that at the regions just mentioned, where the plates 50, and 51, of the cross brace and distance piece 20, are interposed between the flanges 1%, and 15, the latter are in such close proximity to one another that they can be directly socured together by means of rivets, some of which are indicated by the numeral 53, this feature having advantages over the struc ture of my Patent No. 699,943, where the distance between the proximate flanges of the arms is relatively great. At a point intermediate between these spacers, the flanges 14, and 15, are provided with semi-cylindrical offsets 23, and 24:, to receive the horizontal set screws 7 and 8. The flanges 12, and 13, terminate at 21, the other flanges 14, and 15, and the end distance piece 20, being prolonged considerably beyond them. as shown most clearly in Figs. 1, and 11,) so as to be conveniently embraced by the side pieces of the yoke 4, which will be hereafter described. The two arms 2. and 3, converge toward one another, from their points of attachment to the foot. as indicated in Fig. I.

The main structural elements of the foot 1, comprise two angle-irons of L-shaped cross section, whose respective horizontal and vertical flanges are indicated at 30, 33, and 31, 34. The horizontal flanges 30, and 31, may be somewhat reduced in width between the points of attachment of the arms, as indicated at 32, in Figs. IV, and VIII. The vertical flanges 33, and 34, of the foot pieces are spaced at convenient intervals by means of distance pieces 35, preferably tubular and are secured together by rivets 37, and 38, which may extend through the distance pieces.

One of the features of my invention re lates to the connection between the arms and the foot, and will now be described.

I provide for each of the arms, a pair of gusset plates, one member 40, of a pair being shown in perspective in Fig. IX, the other member being a counterpart thereof, except that it faces in the opposite direction. The edge at the inner extremity of the gusset plate 40, is preferably inclined, as indicated at 41, a portion of the upper being recessed, as indicated at 42, and

the adjacent upper part of the plate being bent over to form a horizontal flange 43, in which is an elongated recess 44.

Referring now to Figs. II, and VIII, it will be noted that the gusset plate 40, is secured to the outer side of the vertical flange 33,

upon the foot, and is intermediate between said flange and the inner surface of the flange 17, of the arm 3. Said flange 17, the gusset plate 40, and the flange 33, of the foot piece 30, are secured together by means of rivets 39. The other angle iron of the arm 3, is provided with a complementary gusset plate 45, constructed and applied to the arm and the foot piece 31, 43, in a manner similar to that just described, and the two horizontal flanged portions 43, and 46, of the respective gusset plates meet, as shown in Figs. II, and VIII, so that their recesses 44, and 47, together constitute an elongated opening 5 to ermit the passage of the bolt whereby the foot of the shaft hanger is secured in position, the meeting flanges 43, and 46, constituting the bearing surface for the nut 0r bolthead of the securing devices. At the region overhung by these meeting flanges 43, and 46, the vertical flanges 33, and 34, of the foot-pieces are spaced by distance pieces 48, preferably tubular, through which the rivets 49, may extend, so that the foot pieces and gusset plates are firmly secured to one another at their end portions, as well as at their intermediate portion, and directly at the region of the bearing points of the bolts or other fastening devices whereby the hanger is supported.

The details of the intermediate brace 5, are shown in Fig. V, where it will be seen that a pair of plates 50, and 51, extend across and are received between the proximate flanges of the arms 2, and 3, to which edge they are riveted at 52, and 53. Central olfsets 54, and 55, are formed to admit the vertical set screw 9, rivets 56, and 57, being preferably applied adjacent to these oflsets.

Another feature of my invention relates to the construction and mode of attaching the yoke 4. This yoke comprises two similar side plates, (one of which, indicated at 60, is shown in perspective in Fig. VI,) and the horizontal plate 65, shown in plan view in 5 Fig. VII. The side plate 60, is provided with projecting spuds 62, which enter the holes 66, in the horizontal plate 65, the outer ends of the spuds being upset, if desired, so as to more effectively secure them to said 30 plate. The side pieces 60, have, at their central regions, offset portions as indicated at 61, forming an enlarged vertical opening between them. The extremities of said side pieces embrace the projecting extremities of 5 the flanges 14 and 15, together with the interposed distance piece 20, which extends to the ends of said flanges. A cap piece 67, fits upon the yoke at its central region and forms a bearing for the nut 64, upon the set screw 6, which extends through the en larged opening between the offsets 61, in the side pieces of the yoke, as shown. The ends of the horizontal plate 65, overlap, and abut against the ends of the flanges 12, and 13, of the arms 2, and 3, and are provided with notches 69, which receive the edges of the protruding end portions of the flanges 14, and 15, of said arms. The yoke is removably secured to the ends of the arms, by means of screw bolts 70, which extend through the openings 68, of the sidepieces 61.

It will be seen that those features of the present improvement which relate to the details of the structure at the foot and at the yoke piece are of peculiar value. The gusset plates perform the dual function of strengthening the joint between the leg and the foot, and of serving as the direct bearings for the bolts by which the hanger is secured in position. The horizontal plate 65, of the yoke, constitutes in effect, a continuation of the flanges 12, and 13, of the arms, while the side pieces of the yoke may be likened to prolongations of the flanges 14, and 15. Great structural strength and symmetry are thus attained and the several members may be readily constructed from standard or commercial shapes throughout the entire hanger.

I have used the expression angle irons, in the foregoing specification, as one conveniently descriptive of certain elements, but it must be understood that such expression has no restrictive intention, it being employed there and in my claims as comprehending any flanged structural material of sgibstantially the general character indicate Having thus described my invention, I claim:

1. In a shaft hanger, the combination of a foot-piece comprising a pair of angle irons arranged with their vertical flanges inward; spacingpieces between said vertical flanges; gusset plates embracing said vertical flanges; two arms, each formed of a pair of angle irons, the adjacent flanges of each pair being situated at the outer side of the arm and arranged in relatively close proximity to one another at the regions near the boxsupporting screws, said flanges, at one extremity, engaging the gusset plates and vertical flanges of the foot-piece, and, at the other extremity, being prolonged beyond their correlative flanges; a spacing-piece arranged between said prolonged extremities; rivets extending through the adjacent flanges of said arms; means for securing together the members of the foot-piece and the extremities of the arms with the intervening gusset plates; a yoke, comprising a pair of side pieces which embrace the prolonged extremities of the arm flanges; and means for securing together the side-pieces ot' the yoke and the said prolonged extremities with the intervening spacing piece, substantially as set forth.

2. In a shaft hanger, the combination of arms, each formed of a pair of angle irons;

a foot-piece comprising a pair of flanged members arranged with their vertical flanges inward; spacing-pieces between said vertical flanges; gusset plates secured to said arms and said foot-piece, said gusset plates having horizontal flanged portions which abut together; means for securing the parts of the foot-piece, the gusset plates and the adjacent extremities of the arms together; and a yoke piece connecting the other extremities of the arms, substantially as set forth.

3. In a shaft-hanger, the combination of arms, each formed of a pair of angle-irons, a foot-piece comprising a pair of flanged members arranged with their vertical flanges inward, spacing pieces between said vertical flanges, gusset plates secured to said foot-piece, said gusset plates having meeting horizontal flanged portions with an inclosed aperture, and means for securing the members of the foot-piece, the gusset plates and the arms together.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this thirteenth day of March, 1912.
