JOURNAL-BOX.

SPECIFICATION forming part 0f Letters Patent No.' 697,040, dated April 8, 1902.

Application led March 5, 1901.

To ctZZ whom. t may concern:

Beit known that I, THOMAS H. SYMINGTON, acitizen of the United States, residing at fillnington, in the county of New Hanover and State of North Carolina, have invented a new and useful Improvement in Journal-Boxes, of which the following is a specification.

My invention relates to journal-boxes, and especially to j ournal-boxes for railroad-cars; and the object of my invention is to provide an improved forni of lid and an improved connection between the lid and the box.

Many journal-box lids are pivoted at one side and are kept in place against the faces of the boxes by means of springs. Upon the manner in which a lid is pivoted and upon the manner in which its spring is iitted depends very largely the efficiency of the fit made between the lid and the box-face, and that this lit should be as perfect as possible is well known. The spring is often arranged to bear against the center of the lid; but it should be attached at a point near the pivot of the lid and in such a manner that it can turn with the lid when the latter is turned on its pivot. I have found in practice that to insure a satisfactory fit under all workin g conditions between the lid and the box the lid and its spring should be pivoted independently of one another, that the spring should only bear upon the center of the lid, that the spring should be rigidly attached to a pivot and not merely pivotedupon a fixed pin, and that the lid should bear only upon the actual joint 01 face around the opening infthe end of the box.

The object of my invention is to provide a journal-box constructed in such a manner as to meet these conditions and at the same time economically. f

In the drawings which accompany and form a part of this specilcation, and in which like numerals refer to like parts in the different views, Figure I is a broken view showing the outer end of a journal-box in side elevation and a sect-ion being taken through the point at which the box-lid is pivoted. Fig. II is a front elevation of a journal-box with the lid in position and closed. 'Fig III is a horizontal section through the outer end of the journal-box and the lid. Fig. IV is a hori- .zontal section through the outer end of a j our- Seral No. L19,954. (No model.)

nal-box and its lid and showing a modified construction of pivot for the latter.

In Figs. I, ll, and III, 1 is the outer end of the journal-box. 2 is the lid. 3 is the spring bearing upon the center of the lid and its bearing end kept in place by the lugs 4. 4. On one side of the box is cast a lug 5, in which a hole G is cored. In this hole a bolt 7 engages loosely, so that it is free to turn therein. The bolt 7 is threaded on its outer end, and a nut 8 is run down hard to the end ot' the thread. The spring 3, which is provided with a hole through which the bolt end may pass, is passed over the end of the bolt, and a seco-nd nut 9 is screwed home, so as to jam the spring between itself and the nut 8. The part of the spring which is held between the two nuts is preferablygiven a slight curvature, so that when the outer nut 9 is screwed home the said part of the spring will act as a spring-washer to lock the said outer nut 9.

The lid 2 is provided at its pivoted end with a hole 10 large enough to pass easily over the nut S. The hole l0 is located in an ear 11, the lower edge of which rests upon and is supported by a lug 12, which is preferably cast in one with the box and lug 5. The object of the lug 12 is to provide a solid support for the pivoted end of the lid, and so take the weight of the latter off the nut 8 and bolt 7, for it should be observed that though the lid is actually pivoted on the same center as that upon which the spring is pivoted no part of the weight of the lid is carried by the pivot of the spring. provided with an ear 13, which rests upon the projecting lug 14., which lug is preferably integral with the box. The weight of the lid is therefore supported by the

lugs

12 and 14.. The lid 2 is also provided with a machined face 15, which face bears upon a similar machined face 16, with which the end of the boX is provided, and which face surrounds the opening in the end of the box. It will now be seen that the only part of the box against which the lid bears is the face 16, and the only part of the spring which bears upon the lid is its free end. A central pressure is therefore exerted upon the lid, and this pressure is uniformly distributed around the joint formed between the

faces

15 and 16. The

weight of the lid being supported by the lugs The opposite end of the lid is IOO 12 and 14, there is no necessity for` a ledge along the bottom of the opening in the box end to carry the weight of the lid. Such ledges are objectionable, as, if machined, they are expensive and as they collect dust to such an extent as to prevent the lids coming to a fair seat.

To open the lid, its free end is thrown upward, and if no provision be made against it the pressure of the spring will when the lid is openthat is, standing vertically-cause the lid to cant. Then when it was desired to close the lid again it would be found that a considerable amount of force was necessary to get the lid back to its proper position. Besides, a severe strain would be thrown by the ear 11 upon the heel 18 of the spring and upon the bolt. To prevent this, I extend the face 16 of the box above the lug 5, the said extension 17 also forming a part of the lug for the sake of additional strength, Figs. I and'lII. When the lid is opened, that part of the face l5 ofthe lid which is nearest to the pivot will bear against the extended face 17, and so keep the lid-face 15 in the same plane as the boxface 16; but since the spring bears upon the lid at a point above the extension-face 17 and outside the box-face 16 there is a possibility of the lid canting slightly. This, however, is limited by the heel 18 of the spring, against which the heel 19 of the lid would bear.

It will now be seen that I have a pivoted journal-box lid bearing only on its joint, that this joint'isv kept tight by a central pressure exerted by a lspring not attached in any manner to the lid, that the spring is rigidly secured to a pivot, that the said spring is free to turn with the lid, that the said spring will remain operative at all times, and that its relation to the lid will remain unchanged no matter what the position of the latter may be.

In the form of my invention shown in Fig. IV it will be noticed that the spring 3fL is 'U- shaped and secured at one end only, but that both ends of the spring are turned in the same direction. One end is short and the other long. The spring is attached to the box by the short end, and the long end is turned over the point of support of the' short end and bears at or about the center of the lid of the box. The springs in use in other boxes, while they exert suicient pressure on the lid when new, have so short an extent of-motion due to elasticity that if a very small amount of wear should occur in any of the bearings the long end of the lever would yield so much as to destroy the working power of the spring.

This I prevent by making the spring long, turning it over its point of support, and giving it a large amount of motion for the free end.

The spring instead of being shaped as shown in Fig. IV may have the form shown in Fig. III.

Fig. IV shows another and equally simple manner in which the weight of the lid at its pivoted end may be supported. The supporting-lug 12, Figs. I and II, is dispensed with, and the lug 5 is reduced to form a boss 20. The ear 11 of the lid is provided with a hole 10 large enough to take the boss 2O loosely, and the boss thus becomes a pivot upon which the lid may turn and by which a part of the weight of the lid may be supported, the rest of the said weight being carried, as before, by the lug 14. made conical in shape to facilitate casting and the fitting of the lid. The nut Sis in this case made of larger diameter than in the rst case to present a surface extending beyond the face of the end of the boss 2O against which the heel 19 of the lid4 may bear when the lid is open.

I do not confine myself to the details of construction shown and described, for it is manifest that some of them may be changed without departing from the general principle. For instance, the nut 8 may be replaced by a solid collar integral with the bolt 7, the head 21 of the bolt being at the same time replaced bya nut secured against turning in any suitable lnanner. Also it is not necessary that the nut 8 should lie within the hole 10 in the lid, Fig. III, for by simply lengthening the bolt 7 the said nut can be brought outside the lid, if desired, the hole 10 in the lid being reduced to such a size as will easily admit the bolt.

Having now described my invention, what I claim, and desire to protect by Letters Patent of the United States, is

The boss 20is IOO 1. The combination with a journal-box of a y y lid loosely pivoted at one end thereto, a bolt pivoted in the box, and a spring rigidly secured by one end to the end of the bolt and bearing at its free end upon the lid to press it upon its seat on the box, the lid, spring, and bolt turning together when the lid is opened. 2.
