iaaaooa Specification of Letters Patent.

Application led February 14, 1917. Serial/No. 148,509.

To` all whom t may concern:

Be it lmown that I, WAVLTER S. ADAMS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented. certain Improvements in Journal-Box Lids,

' of which the following is a specification.

dMy invention relates to certain improvements 1n lids for journal boxes for car axles.

One object of my invention is to provide a lid which can be readily opened and closed and which will remainin either position.

A further object of the invention is to make the lid absolutely water tight when in the closed position. The invention also relates to details'of construction which will be fully described hereinafter. 1

In the accompanying drawings:

Figure 1 is a front view of a journal box illustrating myimproved lid; i

Fig. 2 is a sectional view on the line 2 2, Fig. 1, showingithe lid closed;

Fig.' 3 is a similar view -showing the lid opened; and Fig. 4 is a perspective view showing the spring bearing plate.

Referring to the drawings, 1 is the body of the journal box inadein the usual manner. 2 is the-turned up lip at the lower portion of the box. 3 is alug to which the lid 4 is pivoted by the'- usual pivot pin 5. The, lug is shaped as shown in Figs. 2 and 3 andhas a fiat surface 3a and a rounded surface 3b.

, Directly under the lug is a shoulder 6, which extends the same distance as the sides 7 so that when the lid is \in the closed position, as in Figs. 1v and 2, the inner portion 7 of the lid will rest tightly against the shoulder 6,

upturned lip 2 and the sides 7, excluding water or dust, On the lid 4 is an enlargement 8 forming a recess 9 in which is mounted the spring bearing plate 10, the upper edge of which bears against the lug 3, the lower edge being bent in the form of a Socket 11 to t over a lug 12 projecting into the space9 ofthe portion 8 of the lid. A coiled spring 13 rests in a pocket 14 in the enlargei nient 8 and against the spring bearing plate lOpand acts to hold the lid rinly against the box when the lid is closed, as illustrated in Figr2. When the lid is raised to the open position, as inl Fig. 3, the spring tends to hold the lid inthis position, but when the lid is turned down to a position approximately one-third closed the spring will s'nap\ the lid into the closed position. The enlargement 8 has a hood l5 which extends over the lug 3 so as to prevent the entrance of water into the space 9 n the lid, but, in the event of water passing into this space, I provide a drip opening 16 at ,the bottom of the" space, as shown in Figs. 1 and 2, and this drip opening carries the water to the outside of the lid and away from the box.

ABy this means, l provide a very simple and effective lid, which can be easily moved into the open or the closed position, and which will be rigidly held in either position. By `providing the box with a continuous flat surface formed by the ends of the side members 7 the shoulder 6 and the projecting portion 2, dust and moisture are excluded,

,the portion 7@L sealing the box when the lid ward end; a lug at the upper portion of the `box having a rounded surface and a flat surface; a lid pivoted to the lug and having an inner portion of such a size as to rest against the bearing surface of the box, said lid having an enlargement inclosing a space; a lug on the inner portion of the lid extending into the space; a spring plate mounted on the lug and bearing against the pivot lug on the box; and a spring between the outer wall of the lid and the plate.

2. rlhe combination of a journal box having a continuous bearing surface at the forward end; a pivot lug at the upper end of the box; a lid pivoted to the lug and having an inner portion arranged to t against the continuous bearing surface; an enlargement on the lid extending over the pivot and having a pocket near a point opposite the pivot of the lid; a spring bearing plate resting against the inner portion of the lid and the lug and a coiled spring located in the pocket and bearing against the plate, the lug having a rounded vportion on which the bearing plate travels when moved from the open to liti lll@

having an inner portion bearing against the `continuous bearing surface and an enlargement on the outside of the lid forming a space; a lug projecting from `the inner por- 5 tion of the 11d into the space; a bearing' plate having a curved socket fitting the lug and.

bearing against the pivot lug of the box; a spring located between the bearing plate ana the extension on the lid, the extension having a hood projecting over thepvot lug on the 1o box; said bearing plate being so arranged as to travel on the curved portion of the pivot lug.

' In Witness whereof 'I aix my signature.

WALTER s. ADAMS.
