SPECIFICATION formingpart of Letters Patent No. 789,361, dated May 9, 1905.

Application filed July 26, 1904, Serial No. 218,267.

To all whom, it 7nm7/ concern:

Be it known that I, Janus M. EDwARns, of

New York, in the county of Queens and State of New York. have invented certain new and useful Improvements in Shaft-Hangers; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. In secm'ing shafthangers to ceilings or joists it frequently happens that the hanger has to be secured to an uneven or slanted surface, or while the surface may be uniform it may be necessary to support the shafting at an angle. Under such conditions it has heretofore been necessary to employ bolsters or stringers between the hanger and the surface to which it was to be secured, either to cause the hanger to lie in a truly vertical plane or to be supported at an angle. As h angers frequently have to be suspended from corners and the like, where the work of securing them is rendered difficult, or are of a shape or design to correspond with the grillework to which they are fastened, the employment of stringers o ten increases the necessary time and labor or is rendered impossible. The object of this invention is to overcome these difficulties by provk'ling a hanger equipped with means for adjusting it relatively to its support, whereby the shafting may be held at any slant or angle regardless of the surface from which it is suspended.

In the accompanying drawings. Figure l is a perspective view showing the hanger in position. Fig. 2 1s a top plan view. Fig. 3 IS a side elevation partly broken away. Fig. 4: is an end view. Fig. 5 shows in section the body portion and suspending device removed.

Referring to the drawings, 1 designates the bearing wherein the shaftiug is fitted, which hearing may be of any preferred construction. The hanger comprises a body of I shape in plan view, a suspending-plate 2, carrying the shaft-bearing and pivotally secured to the central connecting portion 3 of the hangerbody, and two end brackets or angle-irons to which the laterals 5 of the hanger-body are pivotally attached and by which the hanger is designed to be secured in place. The plateQ parallels one side of the connecting portion 3 and is capable of being turned axially and secured at any desired point in relation to such side. For this purpose the connecting portion is formed with a pivot-boss 7 and the plate with a recess 8, a locking-bolt 10 being passed through coincidentapertures to bind the parts together. The side face of the connecting portion 3 and the adjacent face of the bearingplate 2 are formed with corresponding serrations 12, radiating from boss 7 and the recess 8 of the two parts. In this way such parts are more firmly locked together when bolt 10 is tightened. The connecting portion 3 is formed with upper and lower curved slots 13 to receive additional locking-bolts 15, carried by the bearing-plate 2. \Vhen it is desired to adjust this plate relative to the hanger, bolts 10 and 15 are loosened, the plate 2 is drawn away from the connecting portion 3 sufiiciently to disengage the serrations, but without entirely withdrawing from boss 7, and then the plate is turned axially the desired extent, whereupon the bolts 10 and 15 are again tightened and the serrated faces drawn close together. Then, whether the hanger is supported truly horizontally or set on an angle, the suspended bearing-plate may readily be caused to lie vertically or obliquely, as conditions may require.

The end brackets or angle-irons 4 are designed to be secured to the joists, ceiling, floor, or other point at which the hanger may be desired by nails or bolts passed through their horizontal portions 16. The vertical portions 17 are preferably secured to the laterals 5 of the hanger by means similar to that by which plate 2 is secured to the central portion that is, the meeting faces are formed with the eorrespomling radial serrations l8, pivot-bosses l9, recesses 20, curved slots 21, and bindingbolts 22. The top surfaces of the laterals are of substantially conical formation to prevent their extending above the angle-irons when the latter are turned axially. The upper end of the bearing-plate is similarly formed for the same purpose. Thus the respective angle-irons may each be independently adjusted axially With relation to the laterals 5, and consequently though the ceiling or other supporting-surface be slanted With relation to the direction of the line of shat'ting and Whether or not such slant be uniform at the points at which the two angle-irons are secured the body portion may be caused to hang vertically or at any desired angle.

From what has been said it will be seen that I have provided simple and etficient means for efl'ecting the universal adjustment of the hanger and that a device constructed in accordance with my invention is inexpensive and not liable to readily become deranged.

I claim as my invention 1. In a hanger, in combination, a stationary member, means for securing the same to a ceiling or othersupporting-surface, a bearing, and suspending means, said securing and suspending means being adjustable in planes at right angles to each other.

2. In a hanger, in combination, a stationary member, independently-adjustable devices carried by said stationary member for securing the same to a ceiling or other supporting-surface, and a suspending device secured to said stationary member.

3. In a hanger, in combination, an approximatel y I-shape stationary member, axially-adjustable angle-irons carried by the laterals thereof and designed to be secured to a supporting-surface, and a suspending device secured to said stationary member.

at. A hanger having an approximately I- shape stationary member, axially-adjustable securing means carried by the laterals thereof, and an axially-adjustable suspending device carried by the body portion of said I- shape member.

5. In a hanger, an I-shape member. means for securing the same to a ceiling or other support, the body portion of said member having a boss formed in one side, a suspending device having a plate formed with a recess designed to accommodate said boss, and means for securing said plate to said body portion.

6. In a hanger, an I-shape member, means for securing the same to a ceiling or other support, the body portion 01 said member having 1 radial serrations, a suspending device having a plate also formed With radial serrations, a pivot-bearing for said plate, and means for securing said plate to said body portion.

7. In a hanger, an I-shape member, a supporting device carried by the body portion of said member, the laterals of said member having bosses, su pporting-brackets or angle-irons having recesses designed to accommodate said bosses, and means for securing said angleirons to said laterals.

8. In a hanger, an I-shape member, a supporting device carried by the body portion of said member, the laterals of said member having bosses and radial serrations, supportingbraekets or angle-irons having recesses designed to accommodate said bosses, said angle-irons having radial serrations, and means for securing said angle-irons to said laterals.

In testimony whereof I have signed this specification in the presence of tWo subscribing Witnesses.
