SHAFT-HANGER.

Application filed July 6, 1915.

To all whom it may concern:

Be it known that I, GI-IARLES J. JAoKsoN, a citizen of the United States, and a resident of Easton, in the county of Northampton and State of Pennsylvania, have made and invented certain new and useful Improvements in Shaft-Hangers, of which the following is a specification.

This invention relates to a shaft hanger, and has in view the provision of a shaft hanger which will possess a high degree of rigidity and strength and at the same time will be light and durable in construction and formed with interchangeable parts, whereby a large number of different sizes of shaft hangers may be carried in. stock in a disjointed condition without requiring the stocking of a complete hanger of each and every size, this latter feature being realized by reason of the fact that different sized hangers employ or utilize partsof the same or uniform size.

A further object is to provide a shaft hanger which is built up of a number of parts, so that the device is of a skeleton nature, which, in addition to incorporating therein a high degree of strength, allows the device to be economically manufactured, and the parts are so organized and arranged that it is adapted to support a shaft from the ceiling or above the floor, and provides for the large range of vertical adjustment in either case.

A further object is to'provide a bearing for use in connection with the foregoing, which is adapted to uniformly lubricate a shaft throughout the entire supported length thereof, the means by which the uniform lubrication of the shaft is accomplished being utilized to take up and compensate for any irregularities or slight twists in the shaft.

Other objects and advantages will appear as the description proceeds, wherein it is to be understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed without departing from the spirit thereof.

The preferred embodiment of my invention is disclosed in the accompanying drawings, wherein Figure 1 is a View in longitudinal section of a bearing embodying the characteristic features of my invention and especially adapted for use in connection with my im- Sp'ecification of Letters Patent.

Referring specifically to the several views, the shaft hanger is formed with the base plate 15, the central portion of which is bridged or offset, as at 16, and to which bridged portion are secured the supporting standards 17. The supporting standards, of which there are four, are formed as U- shaped rods or bolts including the threaded ends 18, and the laterally extending connecting portions 19, the latter projecting across and beneath the bridged portion 16 of the base plate. These standards are rigidly and firmly secured to the base by the anchoring plate 20, the same including the beveled edges 21, which contact with the connecting portions 19 of the standards and force them into wedged engagement with the sides and top of the bridged portions 16 of the base plate. A clamping bolt 22, with the securing nut 23, extends through suitable apertures formed in the bridged portion 16 of the base plate and the anchoring plate 20, and draws the two forcibly together, resulting in the most rigid and fixed securement of the standards to the base plate. The supporting standards being formed from U- shaped bolts or rods and the base plate being struck from a steel or iron plate, allows the hanger to be economically manufactured, and at the same time a high degree of rigidity and strength is embodied therein due to the frame-like construction of the hanger and by virtue of the side braces 24, which extend between and are clamped to the outer ends of the base plate and to the intermediate portions of the standards. These side braces extend at an angle to the standards and are provided at their one ends, with the heads 25, which span the adjacent pairs of standards, and are rigidly secured thereto, as presently explained.

In order to properly secure the bearing to the shaft hanger, the cross head 26 and saddle plate 27 are provided, and are so spaced as to receive the bearing 28 therebetween. The cross head 26 is provided with the outstanding sides 30, along the outer faces of which extend the V-shaped notches 29. Suitable clamping bolts 31 extend through the outstanding sides 30 of the cross-head and the adjacent portions of the side braces 24, resulting in the rigid securement of the two to the standards.

The considerable range of adjustment is rendered possible by the outstanding sides 30 of the cross head, as the latter may be inverted so as to bring the same closer to or removed from the bearing 28, as desired. A bearing stay-bolt 32 extends through and threadedly engages the cross head 26 and is held in adjusted position with relation thereto and in contact with the bearing 28 by the lock nut 33. r

The saddle plate 27, upon which the bearing rests, is provided with the socket 34, into which projects the ball 35 of the bearing, thus allowing for a slight rockingof the bearing. The saddle plate spans the distance between the standards 17 and is provided with the V-shaped notches 35', through which the said standards extend, and a rigid securement is effected therebetween by the saddle clamping plates 36, the same being also provided witlrV-shaped notches 37.= Suitable bolts 38 extend through openings formed in the saddle plate and the saddle clamping plates and provide for the rigid securement of the saddle plate to the standards 17. 'The securement therebetween is furthered by the holding nuts 39, which are threaded upon the extremities of the standards 17, and bear against so as to support the weight of the saddle plate. 7

In some instances, it is desirable that the bearing 28 be supported at its sides as Well as at the top and bottom, and with this in view, the saddle clamping plates 36 are provided with the upstanding arms 40, which project above the center of the bearing and are provided with the slots 41 therein, the same being adapted to contain the bearing stay bolts 42. These stay bolts 42 contact with the sides of the bearing and aid in the securement thereof, and the elongated nature of the slots 41 allow the said stay bolts to be shifted so as to compensate for the vertical adjustment of the bearing.

The saddle plate is provided, in addition to the socket 34, with the central and threadof the bearing illustrated, should it be so 7 desired.

The shaft hanger, as previously outlined, may be utilized to support a shaft to one side of the shaft hanger, as illustrated in Figs. 5 and 6, and in these instances, an elongated bolt 22 is employed for holding the anchoring plate 20 to the bridged portion of the base plate, which bolt passes through the opening within the cross head 26 and aids in the securement of a somewhat slightly modified form of saddle plate 27 This saddle plate is modified to the extent only that it includes a projecting portion 44, which protrudes to one side of the standards and has the U-shaped yoke 45 secured thereto. The yoke includes the threaded extremities 46, which extend through suitable apertures in the protruding portion 44 of the saddle plate and which is rigidly secured thereto by the holding nuts 47. Suitable bearing stay bolts 48 extending through the yoke 45 and contacting with the bearing 49 hold the same properly in place.

The shaft hanger, as previously described, is also adapted for use as a fioor stand, as illustrated in Figs. 7 and 8, and in this case the saddle plate 27 and saddle clamping plates 36 occupy the position nearerthe base plate '15, While the side braces 24 are rigidly secured thereto, and are provided with the slotted upper extremities 50, through which the clamping bolts 51 extend.

The cross head 52, which is utilized with the floor stand, consists of a plate which is provided with the spaced apertures 53, which receive the outer and threaded extremities 18 of the standards therein, and is rigidly held in place thereon by the securing nuts 54. In order to support the saddle plate 27 in its elevated position, the anchoring bolt 55 is provided, and of such length that it extends to and contacts with the said saddle plate and acts as: a supporting post there for. The slightly modified form of hanger illustrated in Fig. 9 is formed with the wide bridged portion 16 of the base plate, and the standards 17' are bent intermediate their ends, so that the lower and connected portions thereof converge, adding materially to the rigidity of the entire device, and in some instances rendering unnecessary the use of side braces, though it is to be under stood in this connection that the modified form of shaft hanger, as illustrated in Fig. 9, may be provided with side braces should it be so desired. This type of shaft hanger is particularly adapted for those instances t ll where a short throw for the shaft is desired, and where a high degree of rigidity and strength is essential.

The learing, illustrated in Fig. 1, and which is particularly adapted for use in the shaft hanger, as above described, includes the usual split shell 56, composed of the upper and lower portions 57-58 respectively. The upper portion 57 has the bearing metal 59 secured directly thereto, while a bearing metal supporting plate 60 is mounted in the lower portion 58 of the shell and contains and supports the lower bearing metal 61. In order to further aid in the ability of the bearing to overcome any slight irregularities or twists in the shaft, the shell is provided with the hollow downwardly projecting ball 35, the mouth 62 of which defines a socket adapted to receive and act as the sole support for the ball 63 which pro jects from the bearing metal supporting plate 60.

In order to provide for a substantial uniform distribution of lubricant throughout the bearing, the same is provided with the usual oil wells 64-, and in connection with the oil rings 65 are adapted to lubricate the shaft in the customary manner. The oil rings being located near the ends of the bearv ing do not efficiently lubricate the central portion thereof, and in order to accomplish the same, a wick 66 is provided and eX- tends along a groove 67, longitudinally of the bearing metal, which groove communicates with suitable openings 68, leading down into and communicating with the opening 69 formed within the hollow ball The wick is wound around itself several times within the receptacle 69, which constitutes in fact, an oil chamber, which, in conjunction with the wick 66, promotes the uniform distribution of lubricant throughout the entire length of the bearing and, furthermore, provides for the lubrication of the ball and socket joint between the bearing shell 56 and the bearing metal support plate 60. The ends of the wick pass down through suitable openings 70 formed in the bearing metal and are held properly in place thereby.

In connection with the foregoing, it is to be understood that in heavy and large shaft hangers, the anchoring plate 20 may be pro vided with additional anchoring bolts similar to 22, which will be preferably located at each corner thereof, such additions and changes coming clearly within the scope of my invention, and it will be also understood in this regard that the V-shape notches 29 upon the cross-head 26 and clamping members 25, may be omitted should the use to which the shaft hanger is put so warrant.
