JOURNAL-BEARING.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed February 21,1905. Serial No. 246,741.

To all 20710112 it nt/rg (o/warn:

Be it known that I, THnonoRn C. FRosT, a citizen of the United States, residing at Carthage, in the county of Hamilton and State of hio, have invented certain new and useful Improvements in Journal-Bearings, of which the following is a specification.

It is the object of my invention to provide a new and improved journal-bearing forshafts or the like which will minimize the danger of the bearing or journal becoming heated, to provide movable take-up strips for the hearing arranged in such a manner that they may be caused to take against the journal without danger of too close a fit between the bearing and thejournal, and, further, to provide means which will permit wear upon the bearing to be taken up in convenient manner; and my invention consists in providing a bearing with movable take-up strips whose edges are adapted to take against the journal and which are arranged to be rigidly held in place for forming the bearing; and the invention will be further readily understood from the following description and claims and from the drawings, in which latter Figure 1 is a cross-section of my improved device, taken on the line :1: a; of Fig. 2. Fig. 2 is a plan view of the same with the oil-covers removed for better illustration of parts. Fig. 3 is a plan view of the stationary part of the bearing. Fig. 4: is a perspective view of the clamping-plate having the oil-cover attached thereto, and Fig. 5 is a perspective view of one of the take-up strips.

A represents the stationary or main part of the bearing, which may be cast with or attached to a frame B, which frame may be part of the main frame of the machine in which the bearing is to be used or may itself be a movable part, the reference to the part A as the stationary or main part being intended as meaning that it is the part to which the adjustable parts of my improved device may be secured.

O represents the journal of the shaft intended to have bearing in my improved device.

D represents take-up strips whose inner edges take against the journal and which are preferably given adjustment so that the bearing edges of the strips may be relatively moved toward or from the journal for makingjust the proper contact against the journal for forming proper bearing therefor. These strips,

as shown, are independently movable. he strips are then rigidly secured in place and the bearing thus formed. If there should be any uneven wear against the strips or if the journal should become loose from other wearor cause, the securing means may be relieved and the take-up strips be again moved against the journal for again forming the proper journal [it between the bearing and journal. Various means for permitting the proper movement or adjustment of the strips and securing them in place may be employed, and I have shown such means in the drawings. Thus E E are clamping-plates provided with slots 0. The take-up strips D are provided with slots (1. Bolts F pass through the respective slots of the clamping-plates and take-up strips and are threaded into the stationary part of the bearing, as shown at (a, washers f being interposed between the bolt-heads and clampingplates. The inner edges of take-up strips and clamping-plates take against the journal. In order to prevent too close impact of said strips and plates upon the journal, I prefer that said strips and plates be pressed against the journal by hand or by means of a small stick of wood or other convenient similar device. The take-up strips collectively preferably have parallel side faces, so that they may be readily independently pushed inwardly toward the journal.

For economy the inner-edges of the take-up strips may be respectively provided with a facing (1' of high-grade bearing composition or metal-such as genuine Babbitt, bronze, or the like-the main body (Z of the take-up strips being of cheaper material or baser metal, as cheap Babbitt or other material, to which the facing d is rigidly secured, as by being dovetailed thereto, as shown by the dovetails (Z The inner edges of the clamping-plates may also be provided with a facing a of such high-grade bearing material, the main body thereof being, fol-instance, of iron, to which the facing a is attached by means of dovetails a I The clamping-plates are provided with side walls 1:, pro ecting toward each other forforming an oil-receptacle G, a porous strip H, of felt or the like, taking between the clamping-plates and the side walls thereof and acting as an oil-wiper for the journal. An oilcover I is hinged at 2' to one of the clampingplates and takes over the oil-receptacle G.

An oil-channel K has an oil-cover L hinged be left between the latter and the outer takeup strips to permit the taking up of said outer strips.

Having thus what I claim as new, Letters Patent, is

l. A journal-bearing provided with take-up strips arranged side by side and arranged to be independently pushed manually in common direction toward the journal, and means for securing said strips in place.

2. A journal-bearing provided with take-up strips arranged side by side and extending longitudinally of the journal-bore of said bearing and arranged for being moved in a common direction toward said journal-bore for reducing the diameter of said bore, and means for securing said strips in place, said take -up strips having parallel sides.

3. In a journal-bearing, the combination of a main bearing part, take-up strips arranged side by side, said take-up strips having independent slots registering with each other, and means taking through said collective registering slots for permitting independent movement of said strips and clamping said take-up strips to said main bearing part.

4:. In a journal-bearing, the combination of a main bearing part, take-up strips arranged fully described my invention, and desire to secure by side by side longitudinally of the journal-bore of said bearing and normally having free and independent movement across each others sides toward and from said journal-bore for varying the diameter of said journal-bore, and fastening means for said strips acting solely by pressure upon the sides of said strips.

5. In a journalbearing,the combination of a main bearing part, a clamp-section, a set of take-up strips between said clamp-section and in bearing part, and means permitting said take-up strips to be independently moved in a common direction toward the journal-opening of said bearing, substantially as described.

6. In a journal-bearing,the combination of a mainbearing part, a clamp-section, a set of take-up strips between said clamp-section and main bearing part, and clamping means passing through said take-up strips between said clamp-section and main bearing part, said take-up strips having registering slots about said latter means, substantially as described.

7. In a journal-bearing, the combination of a main bearing part, a pair of sets of take-up strips, the take-up strips of each of said sets having sides parallel with a tangent of the circle of the bore of said bearing, said tangents being diverging, and means for independently securing said sets in adjusted positions.

8. A journal-bearing embodying take-up strips having parallel side faces and arranged to be moved in a common direction toward the journal-bore of said bearing for taking up wear and comprising high-grade bearing-material facings at their journal edges and bodies of lower-grade material, substantially as described.

In testimony whereof I have signed my name hereto in the presence of two subscribing witnesses.

Witnesses JAMES E. HIRST, JOHN F. KRENK'EL.
