JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent N 0. 597,616, dated January 18, 1898. Application filed July 29,1896. Serial No. 600,956. (Model-F fication.

My invention relates to journal-boxes; and it consists of certain novel parts and combinations of parts particularly pointed out in the claims concluding this specification.

In the accompanying drawings I have illustrated my present invention in the form which is at present preferred by me 5 but it will be understood that various modifications and changes may be made without departing from the spirit of my invention and without exceeding the scope of the concluding claims.

In the annexed drawings, Figure l is an end View of the journal-box shown in Fig. 2 looking in the direction of the arrow 1. Fig. 2 is a side view of the journal-box, and Fig. is a top View of the same looking at Fig. 2 in the direction of the arrow 3.

Referring to Fig. 2, Si is the bottom jourrial-box section, and 31 the base or frame in which it is set. 35 is the upper journal-box section. In the base or frame 31 is a projection provided with a set-screw 37 and a jamnut 38. 36 is a facing-piece, against which the set-screw 37 impinges. Theljournal-box section 34 being in position, the facing-piece 36 is placed upon its side and the screw 37 screwed in to hold the section 34. in place. The journal-box section 35 is free to follow lateral movements of the shaft, thus being self-adj usting to avoid friction due to bind ing in its hearing. The binder 39 is provided at one end with a bolt and nut 41. It is pro vided at the other end with another bolt and nut 42. 4:0 is a projection forminga rocking bearing for the binder. a3 is a set-screw carried by the binder and bearing against the base 31.

Assuming that the parts are in the position shown in the drawings and that it is desired to bring the box-sections closer together to take up wear, the set-screw 43 is unscrewed a suitable distance and the nut 42 is eased up. The nut 41 is then screwed down as far as it will go. That end of the bin der 39 which is pierced by the bolt will during this operation describe an arc of a circle, due to the fact that the projection 40 at the opposite end acts like a rocker. About the contactpoint between the lower end of the projection 40 and the surface of the base 81 the binder 39 rocks when the nut 4:1 is screwed down. The box-section 35 having thus been brought nearer to the box-section 34, the set-screw 43 is now screwed down as far as it will go and the nut 42 is again tightened. The whole structure is now absolutely rigid, the binder 39 being at both ends rigidly held with reference to the base 31. At one end it is thus rigidly held by the coaction of the projection 40 and the nut 42, and at the opposite end it is rigidly held by the coaction of the setscrew 43 and the nut ail. A rigid rapidlyadjusted jou rnal-box is thus provided.

The j ournal-box section 34 is shown as being made separate from its support and removable, the surfaces of the base and the journal-box section being trued, so that the parts are interchangeable; but, if preferred, this part might be made integral with the frame.

It is well understood that an efficient journaLbox should be provided with some means for adjustment to take up wear. Various means have been suggested, but all of which I have knowledge are open to one of several objections. To be thoroughly eiiicient the adjusting means should not interfere with the rigidity and exact location of the parts when in use and, while not sacrificing this impor tant feature, should be capable of easy and speedy adjustment. My present invention is directed, among other things, to this end. By the adjustment heretofore described the upper and lower journal-box sections may be brought together or separated wider apart quickly, while the device at every position of adjustment is rigid and the parts can be depended upon to remain accurately in the positions in which they are placed. While the journal-box. section 35 does not during adjustment move toward the journal-box section 34: in scientifically right lines, (since the box-section 35 rocks in approaching the boxsection 34, as already pointed out,) the variation from these lines is so slight as to be immaterial.

In the foregoing specification I have incidentally referred to some of the modifications which might be adopted in the practice of my invention; but I have not endeavored to' specify all the modifications which might be employed, the object of this specification being' to instruct persons skilled in the art to practice my invention in the form at present .preferred by me and to enable them to under stand its natnre,and I desire it to be distinctly understood that mention by me of a few modifications is in no way intended to exclude dicated in the concluding claims, Where the omission of an element or the omission of reference to the detail features mentioned is intended to be a formal declaration of the fact that the omitted elements or features are not essential to the invention therein covered.

What I claim is-- 1. In a journal-box, the eombinationgvith a frame and lower journal-bearing section, of a rocking binder, means for adjusting the same, and an upper journal-bearing section free to move With the shaft. 7

2. In a journal-box, the combination, with a frame and a removable journal-bearing section of a rocking binder, means for adj Listing the same, and a journal-bearing section free to move With the shaft.

Signe'd at Brooklyn, in the county of Kings and State of New York, this 9th day of July, A. D. 1896.
