Application filed March 26 1913, Serial No. 756,926. Renewed June 24, 1918 Serial No. 241,690.

To all whom it may concern:

Be it known that I, HOWARD T. HALLO- WELL, a. citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Shaft- Hangers, of which the following is a specification.

My invention relates to shaft supporting elements familiarly known as hangers, and consists of certain improvements in pressed sheet metal structures whereby I am enabled to {produce a highly; satisfactory article from relatively thin metal sheets; such construction including means in the shape of reinforcements for materially strengthening the same at vital points. An important object of my invention is to provide a structure which, in addition to its required and desired strength, shall possess considerable grace of contour and design and yet be simple in construction, relatively cheap and easily manufactured. \Vhile the general contour and arrangement of the parts making up my hanger are similar to those shown and described in my prior Patent No. 767,225, the feature of my present invention is the character of the reinforcing and connecting means employed for the purpose of strengthening the leg and foot of the hanger, particularly at the junction point of such leg and foot, whether integral or not, and the method or mode of assembling, shaping and attaching such reinforcing means with said leg and foot.

These and other features of my invention are more fully described hereinafter, reference being had to the accompanying drawings forming part thereof, in which:

Figs. 22, 23, 24: and 25, are views illustrating details of the construction shown in Figs. 1, 2 and 3, and

Figs. 2c, 27, 2s, 29, 3o, 31, 32, 33, 34, 35, 36, 37, 38 and 39, are views showing modified constructions of various details of my improved hanger structure within the scope of my invention.

Shaft hangers of the type to which the details of construction forming the subject of my invention have been applied, comprise in general legs of pressed up sheet metal, and in the present instance, such legs, indicated at'l, have substantially centrally disposed longitudinal ribs 2 extending throughout their length, while their'upper ends terminate in feet 3, preferably horizontally disposed for proper attachment to a. support. The legs of my improved shaft hanger are provlded with inwardly dis-- posed rolled or beaded edges 4: throughout their length, and in the formation of the .finished hanger said legs are preferably con-' nected together at their lower ends 5 by a suitable cross-piece, such as the cradleshaped structure illustrated at 6 for instance, which cross-piece may be secured to said-lower ends of the hanger legs, which are made substantially square to be embraced by the ends of said cross-piece 6, by

bolts 7, as indicated in Fig. 1. In addition,

the legs are connected together at a substantially central point by a cross-piece 8, more clearly illustrated in Figs. 3 and 3 which cross-piece may be made from a blank such as shown in 3 and comprises a doublewalled structure having top and

side webs

9 and 10, with flaring ends 11 which fit under the beaded edges of the legs. In addition the side webs are pressed up at 12 for a purpose to be described, and raised portions 13 may be formed at the angle between said side webs and the flaring ends to strengthen them. Their flared ends are connected to the legs by rivets 14; plates 15 being preferably interposed between the flaring ends of said cross-piece and the inner wall of the legs; such plates giving a finish to the inside of said legs. The cross-pieces (S and 8 carry bolts 16, with suitable inner and outer lock nuts 17, "and washers 18, whereby a journalbox 19 may be properly disposed and sup ported in the hanger structure, and the latter may also be provided with horizontally disposed positioning bolts 20 for engagement with said journal-box.

The legs are shaped by bending or otherwise turned outwardly at their upper ends by suitable means to form the feet 3, whereby the hanger may be applied to a beam, joist, girder or other supporting structure, and these feet are slotted or apertured at 21 for the passage of bolts 22 whereby said hanger may be properly secured in place.

In the use of hangers of this type, lateral play of the same, due to any longitudinal movement of the shaft, tends to strain the feet at the bolt connections and cause the hanger to get out of plumb, thereby affecting its utility, and in many instances destroying its usefulness. To avoid this difficulty, I propose to provide reinforcing means for use at the junction of the leg and foot and extending into the foot; the reinforcing means and the leg being preferably bent simultaneously, thereby forming a reinforced foot element at a single operation.

Figs. 8 to 21, both inclusive, show the several steps in the method or process of forming shaft hanger legs in accordance with my invention, and the reinforcing means applied thereto comprise a plurality of plates which are applied to the end of the leg and after bending the end portion of the same to form the foot, said plates may be positively connected together by suitable means. v

In Fig. 8, I have shown a partially prepared blank from which the shaft hanger legs are formed, comprising a sheet of metal A, having rolled or beaded edges (1, throughout the greater part of its length and turned in portions a adjacent one end of the same which are continuous With said rolled or beaded edges. This plate with its prepared edges is then placed between suitable dies and formed or pressed into the shape shown in Figs. 11, 12, 13 and l t.

Fig. 11 is a view looking toward the in ner side of the hanger leg, and this figure illustrates clearly the shape of the longitudinal side ribs 2 of the hanger; the squeezing together of the lower portion of the legs to form a substantially square channel construct-ion a for connection with the lower cross-piece 6; the shaping of the upper part of the plate, subsequently forming the foot portion, to receive reinforcing plates B and C whereby such portion of the hanger is strengthened, and the formation of a short vertical rib 64 extending inwardly and, formed in the upper portion of the outer face of the rib 2 of the leg, which rib a cooperates with said reinforcing plates to properly position the latter. The reinforcing plate B extends substantially from side to side of the plate A, while the reinforcing plate C is smaller and rests in a depression 95 23 of the upper part of the rib 2, the latter having a wall 2% against which said plates abut while the lower end of the plate 0 is in engagement with the upper part of the short rib a To give the interior of the hanger structure a finish, I provide the cover plate 15, in which a central strengthening rib b may be formed, and such plate may have beaded or rounded edges 5 which may be engaged by the rolled or beaded edges of the plate A, and when these parts are slipped together in the manner indicated in Figs. 15, 16 and 17, they retain in place the reinforcing plates B and C; the plate 15 being bent or shaped to engage the plate B. The bolt aperture may be centrally disposed, and the plate C is designed as the main reinforcement through which said aperture passes, although two bolts may be employed; passing also through the reinforcing plate B. Figs. 15 and 17 show clearly the manner of assembling the several reinforcing pieces. The end of the leg structure comprising the plates A, B and C and the cover plate 15, is then bent over in the manner indicated in Figs. 18, 19 and 20; Figs. 19 and 20 being, respectively, an edge view and side elevation of the finished leg.

In this bending over of the foot portion. the beaded edge of the plate forming the major portion of. the leg is flattened down against the edges of the cover plate 15, and the internally placed plates B and C are embraced at the sides by the shaped wall of 130 I said main plate. The leg is then provided with the necessary apertures for the reception of the positioning bolts, rivets, &c. i

The modified construction shown in Figs.

4, 5, et seq, comprises a one-piece hanger, by

' which is meant'that the major portion of the legs 1" and feet 3 with a connecting web 6 are in one piece, as shown. The section of metal making up this structure is provided with beaded edges et serving to stiffen and strengthen the same; which beaded edges extend throughout the length of the structure, and reinforcing plates are provided at the junction of the feet with the legs.

1 represents the legs, which are substantially V-shaped in cross-section, with beaded edges et and these legs are substantially parallel with each other from a point 00 to the connecting web 6 while above the point x to the feet, said legs flare in two directions, spreading apart from the vertical axis of the structure, and being partially flattened in the formation of said feet.

In the operation of forming the feet, the

" web of the hanger is depressed as clearly indicated at 25, Figs. 5 and 6, and in this depression, a plate E is placed, and over the same the cover plate 15; the edges of which are caught under the beaded or turned edges 4 of the hanger legs. The legs are subsequently bent into the foot portion of the desired shape, and in such bending operation, the plate 15 is retained by the formation of a wall around the same, as clearly shown in Figs. 5 and 6, and held in place by said plate E which is secured to the leg of the hanger by rivets 26. i

In order to connect the legs of the hanger together and at the same time provide the necessary means of mounting the upper positioning screw for the j ournalbox, this form of hanger may be provided with the form of cross-piece shown in Figs. 1, 2 and 3, or with a suitable cast metal cross-piece 27 such as shown in Fig. at. This cross-piece is connected to the hanger legs by rivets 28 and may be provided with the usual aperture for the passage of a bolt 16 to engage the journalbox, which bolt carries the usual lock nuts 1'7 common to structures of this type. The lower part of the hanger may have an external block 29 shaped to fit the angular wall of the lower integral cross-piece 6 the lower bolt'16 being also provided with suitable lock nuts 17 inside and outside the wall of said cross-piece; one of said nuts engaging the block 29 whereby said lower bolt may be properly supported in position to engage the journal-box.

In the structure shown in Figs. 1, 2 and 3, I preferably connect theupper ends of the legs adjacent the feet by means of .a

having integral ears 36 whichinay be secured to said leg by rivets 37 part of Fig.

member is formed, is shown in Fig. 22. The

end of the finished structure for connection with the leg is shown in Fig. 23, and Fig. 2 1

is a cross-section of the channel member on the line 2424:, Fig. l.

r Fig. 25 is-a sectional view on the line 2525 of the cross-piece 6 connecting the lower ends of the shaft hanger legs.

Fig. 26 shows a fragmentary part of modi fied hanger leg structure in which a single reinforcing member B is held between rolled or beaded edges 1 of the plate forming the leg, and in which construction a cover plate 15 has been omitted. A modified form of connecting member 8 for the hanger legs is also shown. Fig. 27 is a view in elevation of the foot of the structure shown in Fig. 26, and Fig. 28 is an inverted sectional plan view of the leg and foot, showing the centrally depressed portion of the latter having the bolt aperture.

In Figs. 29, 30 and 31, I have shown, respectively, an end elevation partly in section and a vertical section on the line 30-30,

Fig. 29, of another form of hanger leg structure, and an end elevation partly in section of still another form of hanger leg structure, in which different forms of reinforcing means for the junction of the leg and foot are employed.

In the structure shown in Figs. 29 and' 30, the leg is bent at the foot, and a groove or depression 2* following the contour and shape of the longitudinal rib 2 of the leg is also produced in the foot portion, into which portion a single reinforcing plate 13 is placed and given the samecontour as the leg and foot and subsequently secured to the leg by rivets 11; the leg in this instance also having rolled or beaded edges 4 engaging said plate. In this structure, the cover plate 15 is omitted.

In the structure shown in Fig. 31, two reinforcing plates C extendingfrom the leg into the foot, are employed, with a cover and 31, I employ a channel-bar connecting element 35flfor the hanger legs at the feet thereof, which may be secured in place by rivets 43; such element'being disposed in'the depressed portion of the'feet'formed in line with the ribs of the legs.

In Fig. 32, I have shown a cross-sectional View of a hanger leg, illustrating the manner in which the same is stiffened by the use of the cover plate 15.

In Figs. 33 and 3%, I have shown amodified form of cross-bar 8 which is provided with ends 4L5 extending into the ribs 2 of the hanger legs; being confined thereto by rivets 46. This cross bar is in the form of two plates, spaced apart for the passage of the journal-box positioning bolts 16; and blocks e7 may be provided for this purpose through which rivets 46 and 46 pass, In such construction, the cover plate 15 is omitted adjacent the cross-bar connection with the legs. In some instances, I may provide a leg without an integral foot, a separate foot being attached by suitable means after the leg is finished. Such form of leg I have shown in Fig. 35. In Figs. 36, 37, 38 and 39, I have illustrated forms of cast iron feet which may be employed with a hanger leg ofthis type. These feet may be riveted to the legs and the legs may be connected by a bar similar to the bar 35 shown in Fig. l.
