SHAFT-HANGER.

Specification of Letters Patent.

Patented. Dec. 17,1907.

' To all whom it may concern:

Be it known that I, HARALD F. GADE, a subject of the King of Norway and Sweden, (having declared my intention of becoming 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-hangers and consists of a novel form of shaft-hanger formed of structural metal, whereby great.

strength and rigidity are attained; the object of my invention being to provide a structural shaft-hanger of relatively few parts, which parts may be readily assembled in a cheap and effective manner, and provided with reinforcing members at the points of greatest strain; means being further provided for supporting the adjusting devices for the shaft journal-boxes in a manner that will greatly facilitate their use.

My invention is fully shown in the accompanying drawings, in which Figure 1, is a side elevation of one form of the improved structural shaft-hanger form ing the subject of my invention; Fig. 2, is a perspective view of one of the joints of the same; Figs. 3, 4. and 5 aresectional views taken on the lines aa, bb and c-c respectively, Fig. 1; Figs. 6, 7, and 8 are views of modified forms of structural shaft hangers of the same general form as that shown in Fig. 1 and Figs. 9 and 10 are views of details of my invention.

The structural shaft-hanger forming the subject of my invention is one in which the immediate support for the journal box is of d-shape, the portion to which this part is attached having legs of the usual flaring shape of an ordinary shaft-hanger, and being provided with the usual feet for the reception of securing means.

In Fig. 1, of the accompanying drawings, the upper portion of the hanger is substantially U-shaped, having the flaring legs 1 and 2, and a connecting piece 3 integral with the leg 2. Each of said legs extends upwardly and terminates in a foot 4, on the same plane, whereby the hanger may be properly secured in position, for instance to the beam 5. These parts are duplex, as clearly indicated in the sectional views Figs. 3, 4 and 5, and they are secured together by means of rivets indicated at 6.

The immediate support for the journal-box stance, shown in Fig. 9.

indicated at 7 in Fig. 1, has the shape of the letter J, and in this particular instance it is formed integral with the leg member 1. The connection or cross piece 3, formed integral with the leg 2 is secured to the leg 1 in a novel manner, clearly illustrated in Figs. 1 and 2. The duplex portions of the cross piece 3 are cut at the ends and have portions of the flange bent up, as clearly indicated at 8, in Figs. 1 and 2, and these pieces are riveted to the leg 1, as shown. A brace 9 is also interposed between these bent up portions of the cross piece 3, and this brace is also riveted to the leg 1; one rivet being passed through the several plies of the three different parts, while the other rivet passes through the leg and lower extension of the brace 9. A further stiffening of the hanger is provided by the cross brace 10 engaging the cross piece 3. This hanger is provided with several adjusting screws, indicated at 11, to position the journal-box in proper place, and these screws are preferably placed between the plies of flanged sections which form the structure in the manner, for in- It will be understood, however, that I may interpose jam nuts between the journal-box and the flanged members forming the hanger without departing from my invention. The position of the shaft is indicated at 12 by dotted lines.

In Fig. 6, I have shown a form of shaft hanger similar in most respects to that shown in Fig. 1, but one in which the cross piece 3 is provided with a depending extension 3*, which is riveted to the leg 1, and a flanged brace 9 is provided which passes between the sections forming the leg 1 and the sections forming the cross piece 3. This form of hanger will also be provided with the usual adjusting screws for the journal box.

In Fig. 7, I have shown another form of hanger, in which the portion to receive the j ournal-box is formed integral with the leg 1, as in the forms illustrated in Figs. 1 & 6, but one in which the cross piece 3 has an upwardly projecting portion 3', whose flanges pass between the members forming the leg 1, and are riveted thereto.

In Fig. 8', I have shown another form of shaft-han er of this general shape, in which the leg 2 has the journal su orting portion 7' formed inte ral therewith, and the leg 1 is bent to join t e cross piece 3, which is also integral with the leg 2. These several parts are riveted together as shown, and in addition as a further strengthening means, a plate 9 is interposed between the several parts and riveted thereto.

I have shown in the several forms, by means of dotted lines, the position the shaft will occupy in respect to the hanger, but have not thought it desirable or necessary to show the journal-box in place. It will also be understood that each of the hangers will be provided with adjusting screws of the same character as those illustrated in Figs. 1 and 7.

The different forms of structural shafthangers shown in the accompanying drawing are preferably provided with tie-plates 15, which connect the feet 4 of the same, as indicated in several of the figures, and these tie-plates are preferably corrugated by forming the rib 16 in the same, as shown in Fig. 10. The shaft-hanger structures may be further strengthened by providing bracing pieces at the several angles of the same, in addition to those already indicated in the several views, and these angle pieces may be secured to the main body of the structure by means of rivets or bolts.

By having the support for the ournal-box of d-shape, it becomes a simple and easy matter to mount the shaft in place after the hanger has been fitted up. This construction, however, is possibly not as stiff as one in which the support for the journal-box is connected at both sides to the upper portion of the hanger and in order to .gain this advantage of strength, but at the same time not to complicate the matter or prevent the ready mounting and disengagement of the shaft, I provide the connecting link 17, which may be attached to the end 18 of the journal support 7 and extends to a point 19 adacent to'the connection of the leg 2 and connecting portion 3.

I propose to make these shaft-hangers of commercial angle iron, such as bars of T, I and U-shape, which can be found upon the market at all times, in varying weights and sizes and the hanger may be made up in its entirety of such angle bars. The portions of the hanger formed from such bars are se cured together by means of rivets and bolts and adjusting bolts or screws are provided to position the journal boxes.

I claim:
