Specification of Letters Patent.

Application filed August 21, 1906. Serial No. 331,;54.

To all whom it may concern:

Be it known that I, Cnnrsrornnn W. LE- VALLEY, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Shaft-Hangers, of which the following is a specification.

This invention relates to hangers or supports for line-shafting, and has for its object to produce an article of this character of simple construction, possessing great strength and rigidity considering the amount of material entering into its construction, and all the parts of which may be formed from material easily fabricated, such as bar steel.

In the accompanying drawing, which is an elevation or side view of a shaft hanger or support embodying my improvement, I have, for the purposes of illustration, represented a ceiling or over-head shaft support; but it is apparent that by inverting the parts shown a floor support or bracket may by produced, so that, therefore, my invention is not to be limited in its useful application to the exact construction shown.

The hanger is composed entirely of bar metal and the necessary rivets or bolts for uniting the separate parts.

The shaft hanger illustrated embodies the following elements, namely, two depending side members and two cross members connecting the side members, these parts being suitably united to form a rigid structure and inclosing a space 2 in which is located the shaft, A, its bearing or boxing, B, and parts of the screw adjusting devices, C, usually employed in shaft hangers. The side members ofthe hanger are duplicates of each other and each is formed of flat bar metal shaped to have a foot portion 3 for attachment, a main depending and preferably inwardly inclined portion 4, an intermediate angular bend or inset portion 5, and a vertically disposed depending portion 6. The parts 6 of the side members are parallel and have their flat or broad faces opposite each other so as to constitute the sides of the inclosed space 2, and also serve as guides for the shaft-bearing, the latter having at its sides slides 11, 11 arranged to engage with the guides 6, 6. It will thus be seen that the side bars or members of the hanger, and the vertical guides for the shaft-bearing are integral. The upper or intermediate cross bar 7 rests upon the angular or bent portions 5 of the side bars I where it is secured. The outer or lower cross bar 8 extends between the ends of the side members and is so supported that it may be removed or swung to one side in order to open the space 2 for the insertion of the shaft and its supports. 7

The bearing thus far described is exceedingly simple in construction and possesses sufficient strength to adapt it for use in many places. Where, however, the shaft is subj ect to lateral or transverse strains it is desirable to brace and stiffen the hanger to resist such strains, and this I preferably accomplish by means of the brace pieces 9. These are arranged outside the side bars and extend practically from end to end thereof. Each brace extends from the outer portion of the foot 3 of the hanger to a point adjacent to the bend 5 of the side bar, where it is secured to the latter, as by a rivet 10, and extends thence to near the outer end of the side bar Y braced.

What I claim is 1. A shaft-hanger or support comprising side members having the intermediate, substantially horizontal angular inset portions 5 and the outer vertical portions 6 parallel with each other, an intermediate cross member resting upon the said inset portions and connecting the side members, and a cross member connecting the outer ends of the side members, the latter being movable to open the space between the parallel portions, 6, of the side members, substantially as set forth.

2. A shaft hanger comprising side members having foot portions by which the hanger is secured to its support and two cross members these parts being united to form an inclosed space in which the shaft is located, the portion of the hanger inclosing such space being braced to resist transverse strains by braces located opposite to the said inclosed space and external to the side mem bers, substantially as set forth.

3. A shaft hanger comprising side members each having intermediate between its ends an inset portion, and each side member at one end of the hanger being formed into a supporting foot, braces extending from the sald foot portions of the side members to the o posite ends thereof, and being secured to t e side members near their ends and also at points adjacent to the said inset parts,wherey a side member of the hanger is of double truss construction, one truss being above and the other below the said inset part, substantially as set forth.

4. A shaft-hanger comprising side members each having an intermediate inset por tion, 5, and braces for the side members connected thereto near the said intermediate inset portions and also near the opposite findit ereof respectively, substantially as set ort 5. A shaft hanger formed of similar side members each having a foot portion, 3, a

main depending portion, 4, an intermediate inset portion, 5, and a vertically disposed portion, 6, an intermediate cross member uniting the side members at their inset portions, another cross member uniting the side members at their outer ends, and the braces 9 connected with the side members near their opposite ends and also near their intermediate inset portions, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
