JOURNAL-BOX.

Specification of Letters Patent.

Patented Dec. 29, 1914.

' Application filed February 10, 1912. Serial No. 676,912.

To all whom it may concern Be it known that I, ALFRED L. STREETER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Journal-Boxes, of which the following is a specification.

My present invention relates to journal boxes generally, and more particularly to railway car journal boxes having a lid mounted thereupon, and has special reference to the provision of an improved form of cooperating box and lid wherein the lid is hinged to the box.

The principal objects of my present invention are to provide a form of construction wherein a dust tight joint may be attained between the box and lid when the lid is in closed position, to provide means for maintaining such tight joint, to provide improved latching means for holding the lid in closed position against accidental or undesired opening in service, and to provide an improved form of latch construction for such purpose, together with such other and additional objects as, may hereinafter apaear. 1 In attaining the foregoing objects and in gaining certain advantages to be below pointed out, I have provided the construction illustrated in the accompanying drawing, wherein- Figure 1 is a side elevation, partly in section, of a journal box embodying my 1m provements in preferred form; Fig. 2 1s a sectional view, taken on the line II-II of Fig. 1; and Fig. 8 is a sectional view, taken on line III-III of Fig. 1.

Referring first more particularly to Fig. 40 1, it will be noted that for convenience in illustration I have shown my improvements applied to a car journal box of the standard Master Car Builders type, indicated at 10, provided as here shown with a lug, 11, to which the lid, 12, is hinged by means of bolt, 13, passing through said lug, 11, and projecting portions, 1 1, 1 1, of said lid, 12, as is clearly to be seen on viewing Fig. 3. The lug, 11, is provided with cam surfaces, 15 and 16, against which a spring, 17, carried by the lid, is adapted to bear and thereby hold the lid 12 in open or closed position.

For the purpose of providing a dust tight joint between the margins of the open end 55 of the box through which oil and waste are introduced into the box, and the lid, I provide on the margins of both the lid and the box more particularly the lower margins (see Fig. 1) but preferably also on the sides (see Fig. 2) and on the top, when the opening is made substantially rectangular, 00- operating contacting surfaces 18, 19, and 20, 21, lying in different planes. Between the contacting surfaces 18-19, and 20-21, I arrange on the lid and box cooperating contacting surfaces 22, 28, and at the outermost margin of the opening, contacting surfaces 2 1, 25 on said lid and box, both of the pairs of surfaces 22, 28 and 2 1, 25 being arranged at an angle to the pairs of surfaces 18, 19

and 20, 21. The pivot point of the hinge is, as indicated at 13, located behind the planes in which the surfaces 18-19, and. 20-21 lie, and below the center of the lug, 11, the pairs of surfaces 22-23 and 21-25 are preferably disposed in intersecting planes. By the employment of the doubly beveled surfaces, 18-19, 20-21 and 22-23, or 20-21, 22-23 and 24-25, and the off-center disposition of the hinge 13, just described. I attain as well a doubly broken joint and the most intimate contact between the lid 12 and box 10, and the lid portion 14: and thelug 11, and by the employment of all four of the pairs of surfaces just referred to a trebly broken joint rendering the entrance of foreign matter into the box even more unlikely.

For a two fold purpose, firstly: to close the lid upon the box and hold it in closed position at alltimes under service conditions, and, secondly: in order to gain the greatest benefit from the beveled joint formed by the surfaces 22-23, or 24-25, or both, I employ to fix the lid in the closed position shown, and to force it into tighter contact with the box than is possible by the employment of the spring 17 alone, a latch, 26, carried in ears, 27, 27 formed on the lid, 12. The latch 26 is sustained in operative relation relatively to the margin of the box opening, by means of a pin 28, and for forcing the latch downward and against the curved box surface 30 and thereby cause the surfaces 18, 20, 22 and 21, constantly to press upon the surfaces 19, 21, 23 and 25, maintaining the tightness of the joint, I mount on the latch 26 and between the car 27 and the pin 28, a spring 29.

In order that when it is found desirable to remove the latch 26 from the ears 27,

j and without the use of special tools, I'cut away the bearing provided for the latch" 27, either for replacement thereof or of the spring 29, this may be done with facility in the car 27 as indicated at 31, 32, which construction permits of the latch 26being lifted until it is disengaged from the ear 27 v and then tilted for removal, care being used the parts in position for operation. WVhen v to provide bearing surfaces as indicated at 33 and 34in order to prevent tilting of the latch and consequent'release of the pressure of the lid 12 upon the box 10 in service. For further facilitatingthe removal of the latch, the bearing of the latch 26 in the ear 27Imay be given the ovoid form indicated whereupon a movement of said outer end of the latch to alinement with the opening in said ear permits the latch to be projected through the opening by the spring, placing removing the latch, it is necessary only; to apply pressure to its outer endasuinc ent to carry said end beyond the lower ear, whereupon lateral movement of the latch, permit tedby the particular form of the opening in the upper ear releases the entire latch structure. This particular arrangement is of advantage in-that there is no requirement for the'removal or insertion of a'pin structure-in placing the latch in position or removing it, and at the same time enables the positioning or removal to be quickly provided when occasion requires.

Having thus described my invention and illustrated its use, what I claim as new and desire to secure by Letters Patent is: v j 1. In combination, a journal boX having an opening, a lid for closing said opening, spaced ears on said lid, and'a latch structure'removably mounted within said ears,

' said structure comprising a latch adapted Copies of this patent may be obtained for cilitate said action.

to extend through both ears, a pin forming a stop for the latch in one direction, and a spring on the latch, said structure being adapted to be positioned and removed as a unit, one of said ears being cut away to fav ,2. In combination, a journal box having an opening, a lid for closing said opening, spaced ears on said lid, and a latch structure removably mounted within said ears, said structure comprisinga latch adapted to extend through both ears, a pin forming a stop for the latch in 'one direction, and a spring on the latch, said structure being adapted to-be positioned and removed as a vunit, one of said ears having an ovoid aperj-f ture to facilitate such action.

3. In combination, a journal box having an opening, a lid for closing said opening, spaced ears, on said lid, and a latch structure removably mounted within said ears, said structure comprising a latch adapted toextend through both ears, a pin forming a stop for the latch in one direction, and a spring on the latch, said structure being adapted to be positioned and removed as a unit, the ear at the inner end of said latch being provided with an ovoid aperture to facilitate the movements of the latch into and out of position.

4-. In combination, a journal box having an opening, a lid for, closing said opening,
