SHAFT HANGER.

SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent NO. 326,789, dated September 22, 1885.

Application filed May To all whom, it may concern:

Be it known that I, Wnnsrna RoBERTs, of Cleveland, Guyahoga county, and State of Ohio, have invented a certain new and 1mproved Shafting-Hanger, the nature of which relates to such a construction and arrangement that when it is suspended in position for re= ceiving the shafting the journal-box of the hanger can be accurately adjusted to the axial line of the shafting without changing the entire hanger for that purpose. Said adjustment is made by simply moving thejournal-box of the hanger to adapt it to the line of shat'ting. Hence the journal-box or the bearing for the shaft, instead of an integral part of the hanger, is a distinct section adj ustably secured in the hanger for the purpose specified. That the construction of the hanger may be fully understood, reference will be made to the accompanying drawings, making part of the following specification.

Figure 1 represents a view of the hanger taken endwise the shaft-ing. Fig. 2 is a view of the hanger shown lengthwise the line of shafting. One arm of the hanger is shown as broken away that the journal-box may be fully seen. Fig. 3 is asectional view taken through the line a: m, Fig. 1. Figs. 4 and 5 are detached sections, and will be referred to in description.

Like letters denote like parts in the drawings, in which A and B represent the arms of the hanger, by which it is suspended. Midway between the two armsis secured asocket, O, by means of the webs D, which also re-enforce the suspending-arms by connecting them to each other, as seen in Fig. 1. 111 the lower end of the socket Cis inserted a movable core,

pair of ears, a a, Figs. 1 and 2. The space between the two ears is in the are of a circle, having its center in the axial line of the setscrew I). Said are of a circle is adapted to the curve of the block F, projecting upward from the top of the cap G of thejournal-box. The said block is an integral part of the cap, as seen in Fig. 3. The curve of the face of the block is described from the center of the are before mentionedviz.,the set-screw b, alluded to. I is a setscrew for securing the core E in the socket, which is vertically adjusted therein by the adjusting-screws J for a purpose presently shown. The lower part of the hanger 4,1885. (No model.)

consists of the Ushaped section K, Fig. 1, provided with ears 0 c,adapted to the ears d d of the hanger,the upper section thereof above described, and to which the lower section is secured by the bolts L. Forming an integral part of the lower section of the hanger is a socket, M, like the socket 0, above described, and has therein a core, N, similar to the core E, and arranged in alignment therewith, as seen in the drawings. The upper end of the core N terminates in a pair of arms, e 6, Figs. 1 and 2, between which depends from the lower section, H, of the journal-box a projection, 0, Figs. 2 and 3. It will be observed in Figs. 1 and 2 that the upper ends of the arms 6 6, all uded to, describe the arc ofa circle, andare adapted to fit, respectively, in corresponding arcs of a circle in the bosses m m, formed on the sides of the section Hof the journal-box. Upon said arms 6 e the box is supported in the hanger, and in view of its curvilineal connection with the arms the journal-box can be vibrated thereon, and which may be made fast in its connection therewith by the adjusting screws h h, which pass unth readed through the arms and are screwed into the projection, as seen in Fig. 5. The core N is made fast in its socket by the setscrew b, and is upwardly supported upon screw Q, as seen in Fig. 3. At the under side of each end of the journal-box is an oil'receptacle, a a, open to the inside of the box by oilways b I), respectively, which are openings made through the plate 0, covering the said oil-receptacles, and forming portions of the inner surface of the box and a supporting-surface for the Babbitt-metal lining d.

Fig. 4 represents an inside view of the lower half of the journal-box without having therein the lining, it being removed that the surface of the plate 0 may be seen, and an open View of one of the oil-receptacles a, above mentioned, its plate having been removed for that purpose. On the top of the journal-box are oilcups A; also, there are oilways in the side of the box, as seen at P P, by which oil is conducted into the oil-receptacles a a. Oilis conducted from the receptacles to the journals by capillary attraction. For that purpose is inserted in the holes 1') b any suitable fibrous material.

Practically the operation of the above-described hangeris as follows: It is necessary in puttingup a line of shafting that every journal-box and bearing of the shaft should be in exact alignment one with the other, that the journals may run without binding in their respective boxes, and thereby avoid heating and undue wearing of the journals and their seats. As hangers are usually made this is a matter of much trouble, to avoid which is the object of the herein described hanger; and when it is suspended in the usual way by the arms A and B, and in close proximation to the line required for the shafting, the journal boxes are then adjusted in exact alignment as follows: In the event a journal box is found to be too low for the shaft-line it can be raised upward exactly to the line of shafting by the supporting-screw Q, acting on the end of the case N, then fastened by the screw b. Should the journal-box be too high for the shaft-line, it can be readily and easily lowered by backing out the screw Q so far as is necessary to lower the coreN far enough to bring the box in exact position to the shaft-line. The core is then secured in the socket by the set-screw b, and the box held down firmly in place by the core E, in the upper section of the hanger, being forced down upon the box by the ad justing-screw J.

From the above it will be seen that the journal-box can be easily and readily raised or lowered in the hanger, as the nature of the case may require, to adjust the box in exact relation to the line of shafting. If the axial line of the journal-box is not horizontal or in line with the shaft, as it should be, the box can bereadily adjusted to thatposition by loosening of the screws h h and then slackening the core E in its socket. The journal box may then be rocked or moved on the arms e e in either direction to bring it to a horizontal position or in such position as the axial line of the shafting may require. The box when thus adjusted is made fast by screwing down the core E, thereby clamping the journal-box between the arms 6 e and the end of the core E,which will hold it firmly in position from any vertical and rocking movement. A third adjustment of the journal-box is made in a lateral direc tion, in order to bring its axial line coincidently with that of the shaftline. To this end the pressure of the. core E, upon the journal-box is released, and one of the screws h in the arms 6 e screwed outward. Thenon screwing the other screw h inward it will draw the journal box laterally, or in the direction of the arrow seen in Fig. 5, to adjust the box to the line of shafting, which is donein the most exact manner. In this position it is secured by turning in the screw h hard against the opposing screw h, thereby clamping the part between the two screws h h. It will be ob vious that the latter adjustment of the jou rnalbox may be made either to the right or to the left, as the nature of the case may demand.

The several described adjustments of the journalbox are made after the hanger or hangers have been put in position approximating an exact one, the close and final adjustment being done as and by the means and in the manner before shown and described.

What I claim as my improvement, and desire to secure by Letters Patent, is-
