HOIVARD T. HALLOWVELL, OF 'HALLOWELL, PENNSYLVANIA, ASSIGNOR TO STANDARD PRESSED STEEL COMPANY, A CORPORATION OF PENN- SYLVAN I A.

SHEET-METAL SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No. 767,224, dated August 9, 1904.

Application filed January 26, 1903. Serial No. 140,487. (No model.)

To a. whom it may concern.-

Be it known that I, HOWARD T. HALLowELL, a citizen of the United States, residing at Hallowell, in the county of Montgomery, State of Pennsylvania, have invented a new and useful Improvement in Sheet-Metal Shaft-Hangers, of which the following is a specification.

My invention relates to a novel construction of a shaft-hanger; and it consists in improvements on prior'patents granted to me and prior patents with which I am familiar in that I employ a construction of hangerlegs, intermediate brace, and yoke, which are assembled in such a manner that the whole forms a strong and durable construction,while the edges of the legs extend inwardly, forming a stiffening or strengthening means.

It further consists of novel details of construction, all as will be hereinafter set forth, and fully pointed out in the claims.

Figure 1 represents a side elevation of a hanger embodying my invention. Fig. 2 represents an end elevation thereof. Fig. 3 represents a sectional view on line m m, Fig. 1. Fig. 1 represents a sectional view on line 3/ y, Fig. 1. Fig. 5 represents a sectional view of one of the legs, taken substantially on the line :0 m, Fig. 1, omitting the brace. Fig. 6 represents a sectional view on line 2 2, Fig. 1. Figs. 7 and 8 represent-sectional views showing a slightly-difi'erent form of the leg.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings,.l designates a hanger, the same comprising the legs 2, each leg being constructed substantially the same and consisting of a hollow trough-shaped member having a strengthening-rib 3 extending throughout the length of the leg, the edges of said legs extending inwardly, forming the flanges 5,which serve to stiffen and strengthen the legs, as will be evident, said flanges extending throughout the entire length of the leg. The lower portion of the hanger-legs are substantially rectilinear, as indicated at 6, and

are adapted to be embraced by the yoke 7, said yoke being adapted to be held in place by the bolts or other fastening devices 8, whereby it will be seen that by the removal of one of these bolts the yoke can be swung downwardly into the position seen in dotted lines in Fig. 1, thereby acting like a hinge. The upper portion of the legs diverge or flare outwardly, while the upper extremity of each leg is provided with a foot 9, which feet are secured in position in any suitable manner.

The intermediate brace 4 consists of the plates 10 and 11, which are secured together by the rivets or other fastening devices 12, the edges of said plates having the flanges 13, which abut against the legs 2, at which point the legs are substantially rectilinear on either side of the strengthening-rib 3 in the present instance, and said brace is secured to the legs by the rivets or other fastening devices 14..

Passing through the brace 4L and supported thereby is the adjusting device for the upper part 15 of the journal-box, said adjusting device consisting of a screw or threaded pin 16, having the head 17 on the upper end thereof for engagement with suitable operating means, while a nut 18 rests upon the brace 4, an additional nut 19 being provided for the pin 16, said nut 19 being situated between the plates 10 and 11, which are flared outwardly,

.as at 20, forming a seat for said nut.

Passing through the yoke 7 is the threaded pin or screw 21, which serves as the adjusting device for the lower part 22 of the'jour- 'nal-box.

In the construction seen in Fig. 7 I provide the same general construction with the inwardly-extending stiffening flanges or edges 5, the rest of the construction remaining the same as heretofore described.

In Fig. 8 I form the strengthening-rib 23 similar to the strengthening-rib 3, already described, excepting that the same extends inwardly between the plates forming the brace 4:; but each leg is provided with the inwardlyextending flange or edge 5.

The horizontal adjusting devices 2a are employed in the present size; but it will be evident that these may be omitted, and in place of the screws 17 and 21 I may use large supporting means for holding the box 15 in position, and in this event slightly-different brace and yoke will be employed.

Although I prefer to use the plate for holding the upper part of the legs in position, yet I could omit this in many sizes. Although I [ind the means shown for securing the brace to the legs is the best, yet I could easily attach a brace to the hollow rib portions 3 of the legs instead of as shown.

I desire to call especial attention to the inwardly-extending stiffeningflanges, which enable me to make the legs of very strong and durable construction Whether employed with the strengthening-rib or not.

It will be evident that slight modifications can be made by those skilled in the art, and I have shown all the modifications which I claim come within the bounds of this invention.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a shaft-hanger, a tapered leg having a body portion, a longitudinal hollow rib upon one side, and longitudinal flanges upon the opposite side thereof.

2. In a shaft-hanger, a sheet-metal leg hav ing a body, a longitudinal strengthening-rib extending from one face of the same and longitudinal flanges extending from the opposite face of the same.

3. A shaft-hanger comprising sheet-metal legs each having a body, a strengthening-rib projecting from one side thereof and flanges projecting from the opposite sides thereof, both the rib and flanges extending longitudinally, and a brace uniting the legs intermediate their ends.

4. In a shaft-hanger, legs, each having longitudinal flanges projecting toward the other, a longitudinal hollow strengthening-rib extending away from the other and a body portion between the flanges and the rib in combination with a brace uniting the legs and embraced by said flanges.
