WILLIAM STEVENSON, OF CHICAGO, ILLINOIS, ASSIGNOR TO CHARLES GILBERT HAW'LEY.

JOURNAL-BOX.

Specification of Letters Patent.

ratented April 23, 1907.

Application filed April 4, 1906. Serial No. 309,855.

To all whom it may concern.-

Be it known that I, WVIL L-mi STEVENSON, a citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented a certainnew, useful, and Improved J ournal-Box, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to journal boxes for car trucks and has special reference to improvements in journal boxes of that class wherein the lid is held by a horizontal hinge on the top of the box.

The object of my invention is to simplify and otherwise improve the construction of journal boxes of the above mentioned class, and particularly to improve the means for holding the journal box lid tightly closed, also, when desired in its opened position.

The special object of my invention is to provide a journal box lid that shall completely close the journal box opening, and to provide means upon the exterior of the box for looking or fastening such lid; a distinct purpose of my invention being to avoid the use of openings in the lid or the use of springs or other devices necessitating either openings or channels in the lid, through which dust might enter the box.

The particular object of my invention is to provide a journal box which shall have an externally locked or spring-pressed lid that shall be interchangeable with the lids of the so-called Master Car Builders type.

A further object of the invention is to provide a journal box having a spring pressed lid and whereof the spring shall be completely enclosed and protected.

Other objects of my invention will appear hereinafter.

My invention in its preferred form coinprises a journal box, in combination with a id, hinged at the top of the box and provided with a locking lug or cam on its upper end and a spring device on the top of said box parallel with the hinge of the lid, and coacting with said locking lug or cam to hold said lid in either closed or opened position.

My invention also consists in various details of construction and in combination of parts all hereinafter described and pointed out in the claims.

stood by reference to the accompanying drawings, forming a part of this specification and in which I have illustrated that form of -iny invention which I prefer:

In said drawings, Figure 1, is a vertical section of a journal box, embodying my invention, the section being on the line a'w, of Fig. 2, Fig. 2 is a plan view of a ortion of the top of the box and lid, and, lig. 3, is a sectional detail, showing the lid in opened position; and also illustrating a slight modilication.

My invention is not limited to a journal box of special form, in other words, it is applicable to any of the journal boxes in ordinary use.

The journal box, A, here shown, conforms substantially to the rules of the Master Car Builders Association, being provided with an end opening, A, and a hinge lug, A, of the types prescribed by said rules. The form of the box is neither changed nor altered to suit my invention except that the top of the box is provided with an additional lug, A", This last, is parallel with the hinge lug, A and is separated therefrom by a space of suilicient size to admit the hood or top of an M. C. B. when such is substituted for the lid hereinafter described. The lug, A, contains the usual hinge pin, C. The lug A, contains an opening that is parallel with the hinge pin and in this I arrange preferably two plungers, D, D, and a spring, D, the latter being adapted to project the plungers from the ends of the lug, A, upon a line or axis parallel with said hinge.

My novel lid, B, has hinge lugs, B 13 ournaled on the hinge pin, C, The flange, B of the lid extends entirely around the end of the box. The lid is solid, containing no openings through which dust may enter the box. On the lid lug, B are two locking lugs or cams, B The inner faces of the lugs, B, are preferably curved, as shown, and the lugs are so positioned as to engage the rounded or tapered ends of the plungers D. D. The latter are forced outward by the strong spring D, and wedging against or under the lugs B firmly lock or hold the lid upon the end of the journal box. The spring-fastening, thus formed, is of such effectiveness, that considerable force is required to open or raise the lid. When the lid is lifted, the lugs, B B,

The invention will be more readily under- 1 force the plungers D, D, into the lug or holder A, but as soon as the lugs pass the centers or crowns of the plungers, the latter spring out and force the lugs downward, thereby assisting in the raising of the lid and securely locking the lid in open position. When desired, I provide the lid with a hood, B, as shown by dotted lines in Figs. 1 and 2 and in full lines in Fig. 3 and in such cases the cams, B are formed within the ends of the hood.

It is obvious that various modifications of my invention as herein shown, will readily suggest themselves to one skilled in the art and I therefore do not confine my invention to the specific construction herein shown and described.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent:

1. A journal box, having a hinge lug, in combination with a lid, a hinge-pin, a cam on said lid and a longitudinally acting spring device on said box parallel with the axis of said hinge pin and co-acting with said cam, sub stantially as described.

2. A journal box, in combination with a lid, hinged at the top thereof and provided with a lug or cam adjacent to the hinge and a spring device on said box, said spring device being parallel with the axis of said hinge and coacting with said cam, to secure said lid in closed and open positions, substantially as described.

3. A journal box, in combination with a lid, hinged on said box and provided with a locking lug or cam and a spring device constantly engaged with said lug and co-acting therewith upon an axis parallel with the axis of the hinge of said lid, substantially as described.

4. A journal box, in combination with a lid hinged thereon and provided with a pair of lugs or cams and a spring device acting upon an axis parallel with the hinge axis of said lid and abutting said cams substantially as and for the purpose specified.

5. A journal box having a hinge lug and hinge pin, in combination with a lid, provided with a lug or cam, a plunger movable upon an axis parallel with the axis of said hinge pin and constantly engaged with said lug on said lid, and a spring pressing upon said plunger, substantially as described.

6. A journal box, in combination with a lid, hinged thereon and provided with a pair of lugs or cams, a co-acting spring, arranged upon the top of said box parallel with the hinge axis of the lid and between said lugs, substantially as described.

7. A journal box, in combination with a lid hinged thereon, a spring holder on said box, a horizontally acting coiled spring held thereby, said spring being parallel to the hinge axis lugs or cams on said lid and plungers interposed between the same and said spring, substantially as described.

8. A journal box provided with a hinge lug, in combination with a lid having hinge lugs, a hinge pin, there being locking lugs or cams on the hinge lugs of said lid and a locking spring arranged on said box between said locking lugs and co-acting with the latter, substantially as described.

9. A journal box, having a hinge-lug, in combination with a lid also having hinge lugs, a hinge pin, a second lug on said box, parallel with its hinge lug, a coiled spring and plungers arranged in said second lug, said plungers having convex ends and coacting cams on said lid, substantially as described.

10. A journal box, provided with parallel hinge and spring lugs upon its top, a hinge pin, a lid, pivoted on said pin and provided with a locking cam, a spring-pressed lunger in said spring lug and a hood on said id partially enclosing said parallel lugs, substantially as described.

11. A journal box having a hinge lug in combination with a hinge pin transverse to the axis of the box, a lid hinged on said pill and provided with two cams, a spring device arranged on the top of said box and movable upon an axis parallel with the axis of said hinge pin, said spring device constantly coacting with said cams to secure said lid in closed and open positions, substantially as described.

In testimony whereof I have hereunto set my hand, this 29th day of March, 1906, at Chicago, county of Cook and State of Illinois, in the presence of two subscribing witnesses.

WILLIAM STEVENSON.
