JOU RNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 472,729, dated April 12, 1892. Application filed December 30, 1891. Serial No. 416,547. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM B. I-IosnoRD, of Mishawaka, in the county of St. Joseph and State of Indiana, have invented new and useful Improvements in J ournal-Boxes and I do hereby declare that the following is a full and accurate description of the same, reference being had to the accompanying drawings, wherein- Figure l is a perspective view of a pillowblock provided with my improvement. Fig. 2 is a central transverse section of the same. Fig. 3 is a central longitudinal section showing the manner of removing Vthe lower box. Fig. 4 is a central transverse section showing the manner of removing the lower box.

This invention relates particularly to that class of journal-boxes which are self-adj usting to the line of the shaft. These boxes are frequently made with transverse rings,which on portions of their outer surface constitute concave segments of the same sphere fitted to corresponding concave surfaces of the pillow-block, so as to form therewith a ball-andsocket joint for the journal-box, wherein it may have a universal movement to adjust its axis to the axis of the shaft.

Boxes of this kind require some device to prevent them from revolving with the shaft and causing their plane of separation to depart from the corresponding plane of the pillow-block, which would prevent the removal of the upper half of the box. Such a device is a stud, always heretofore made a part of the lower half of the box, projecting downward therefrom between lugs or other portions of the base of the pillow-block, so as to prevent rotation of Vthe box without restraining its freedom of self-adjustment. This arrangement has an important and highly-inconvenient defect; and the object of my present improvement is to remedy said defect With- When it is considered that this removal is of frequent necessity for the purpose of renewing the babbitt lining, that the necessity is are commonly heavy, the inconvenience and expense of removing the shaft from all its bearing-boxes in order to get the lower half of one of said boxes out will be apparent toany one having practical acquaintance with motive machinery, and correspondingly the advantage of a structure which will permit the removal of the shaft will be equally ap'- parent.

My invention consists in a restraining-stud projecting upward from the upper half of the box and suitable restraining lugs or surfaces on the inner surface of the pillow-cap, whereby while said upper part of the box and said cap are in place, both parts of the box will be restrained from revolution with the shaft from a position beneath to a position above the shaft. To accomplish this, it is necessary to provide some temporarysupportfor the weight of the shaft while the lower box is absent.

Having now clearly indicated the nature of my invention, I will describe the manner in which I have carried it into operation, without, however, intending to limit myself to the F is a stud projecting from upper part D l of the box and resting loosely between lugs or plates G G, projecting downward from the inner surface of the cap B. When the cap B has been removed, the part D of the box will then be free to be lifted off, uncovering the shaft and removing all impediments to a revolution of the part C of the box from beneath to a position above the shaft, as shown in Fig. 4, when it may also be lifted free from the IOO shaft and may be replaced again beneath the restrain the said boX from revolution with the shaft by movements in reverse order.

Having described my invention, I claim as newl. A self-adjusting journal-box provided with a removable cap having on its inner surface lugs or plates G, substantially for the purpose set forth, combined with a self-adj usting journal-box in two parts C D, as described, the part D being provided with a restraining lug or pinF, adapted to rest between said restraining lugs, plates, or surfaces and thereby shaft, for the purpose set forth.

2. The pi1low-b1ockAand its cap B,provided with the plates G G, pendent from the inner surface of said cap, combined with a self-adjusting j ournal-box C D, provided with a stud F, projecting upward from the upper part D of said box between said pendent plates.
