ADJUSTABLE SHAFT HANGER. APPLICATION man 1uLY1.1915.

CAREY SHERWOOD, 0F LOWELL, MASSACHUSETTS ADJUSTABLE SHAFT-HANGER.
To all whom it may concern.' i
Be it known that I, CAREY Si-innwoon, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvenient in Adjustable Shaft-Hangers, o-f which the following is a specification. I A
This invention relates to adjustable shaft hangers.
The object of this invention is to permit the journal boxes to be adjusted vertically and laterally and to allow the journal boxes and their supports to be removed and replaced without disturbing the alinement of the shaft.
Hangers for shafting are usually supported upon wooden timbers and are liable to be shifted out of position by the shrinkage, eX- pansion and warping of said timbers, throwing the shafting out of alinement and creating unequal pressure and friction on opposite sides of the journal boxes.
I form the hanger proper in two parts, a base or foot adapted to be rigidly secured to a supporting timber substantially immovable, except for the shrinkage, expansion and warping above referred to, and an extension adjustably secured thereto by vertical bolts in such a manner that said extension may have a slight movement transversely of the shaft supported thereby and I provide means whereby said extension may be adjusted to a great exactness.
The extension when properly placed may be held immovable with reference to the base or foot.
The journal boxes are supported upon the same bolts which connect the extension to the base and are laterally movable with said extension and are also adjustable vertically on said bolts toward or from said extension.
In the accompanying drawing, Figure l, is a side elevation of my improved hanger, the foot, extension, yoke and drippenor lower support of the journal box being partly in vertical longitudinal section; Fig. 2, a plan of said hanger with part o f dripper; Fig. 3, a plan of the yoke; Fig. Ll, a reversed plan of the dripper; Fig. 5, represents a lock-nut, one half in elevation at the left, and at the right the other half in vertical central section.
The base or foot A is secured in place by bolts, (not shown) which pass through holes Specification of Letters Patent.
Application led July 1, 1915.

Serial No. 37,611.
a al into the supporting timbers in the usual manner, and is provided with a longitudinal groove a? of a sufficient width to receive the heads b1 of the screw bolts B B1 and to allow said heads to be moved lengthwise of said base but not wide enough to allow said heads to be turned in said groove.
The bolts B B1 pass vertically through longitudinal slots at a5 in the foot A and through holes (one of which is shown at o1 in Fig. l) in the extension C, said extension being normally held against said foot by nuts c2 c3 turning on the bolts B B1 against the under side of said extension.
After loosening the nuts c2 c3 the extension and the parts supported thereby may be moved on the foot A a distance limited by the length of the slots at a5, transversely of the shaft D, that is, to the right or left in Fig. 1, to accommodate the journal-box E laterally to said shaft.
To make such lateral adjustment with great exactness, I provide the foot or base A with two ears a al which reach down for a short distance below the top of the extension on opposite sides thereof and in these ears turn horizontal screws F F1 which thrust against the opposite sides of said extension, the nuts c2 c3 being first loosened so that by loosening either of these screws F F1 and turning the other, the extension will be moved transversely of the shaft. When the extension is so positioned that the journalbox E bears equally upon opposite sides of the shaft, the nuts G2 c3 are tightened and the loosened screw F or F1 is turned against the extension to prevent any movement of said extension.
The journal-box E is or may be of usual form and is represented as supported in a yoke or yoke-shaped dripper or drip-receiver G provided with arms g g1, through in which the bolts B Bl pass and which rest on nuts H H1 and check nuts h h1 and which arms are held down on said nuts H H1 by stop-nuts H2 H3 on said bolts so that when the nuts and check-nuts below said arms are unscreiwed the yoke may be removed from said bolts B B1 without disturbing the stopnuts H2 H3 or the alineinent of the shaft D, and said yoke may be replaced against the shaft in the same position it previously occupied and secured in place. But I have provided said yoke G with slots gf4 g5 of as great width as the diameter of the holes commonly used for the passage of the bolts B B1 through said arms g g1 and integral with said holes which slots open at the sides Vof said arms, so that said arms may be pushed laterally into place or removed there` from without removing the nuts H H1 l1, 71,1 entirely from the bolts B B1. The nuts H H1 are lock-nuts, being each provided with a cylindrical lock 71,2 k3 concentric with the aXis of said nut and the yoke Gr is counterbored at gs 97 concentrically with the semicircular closed end of the slot g4 g5 to receive and fit said lock, so that when such lock is in said counterbore the corresponding arm of the yoke G cannotbe moved.
The upper yoke J is held in place on the bolts B B1 by lock-nuts H H1 and the end portions of the arms y' jl of said yoke J are slotted at i3 j* and counterbored at js j just as the lower yoke or dripper is slotted and counterbored and for the same purpose. It is evident that the upper yoke J and its nuts when held on the bolts B B1l by said bolts passing through round holes in said upper yoke cannot be removed without irst removing the lower yoke C and its nuts, so
that this invention is especially desirable as applied to said upper yoke.
In the case 0f the lower yoke, this invention renders it unnecessary to remove thc nuts from the bolts with the danger of their being lost or mislaid.
This invention enables either yoke to be removed while the other yoke remains in place without disturbing the alinement of the shaft.
I claim as my invention The combination of a bolt, a yoke slotted to receive said bolt and having a counterbore at the inner end of said slot, and a nut turning on said bolt and having a concentric, hollow cylindrical projection, to enter and lit said counterbore and to prevent a lateral movement of said yoke on said bolt in the direction of said slot.
In witness whereof, I have aiixed my signature in presence of two witnesses.
