DUST-PROOF SELF-LOCKING JOURNAL-BOX COVER.

Specification of Letters Patent.

Patented June 2, 1908.

Application filed October 16, 1907. Serial No. 397,731.

To all whom it may concern:

' Be it known that 1, JAMES W. GIBNEY, a citizen of the United States, residing at Buffalo, in the county .of Erie and State of New York, have invented a certainnew and useful Improvement in Dust-Proof Self- Locking Journal-Box Covers, of which the followin is a specification.

This invention relates to an improved means for locking the cover of car journal boxes to the box and the object of the invention is to produce a cover which is self-locking and dust-proof and in which the. cover is automatically centered as it is closed.

'Another object of the invention is to so form the cover and its seat that'there is little or no wear and to so construct the fastening means that there is no likelihood of breakage or loss of parts.

on line a a, Fig.'3'through -a car journalbox" The invention also relates to certain details of construction, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings in which,

Figure 1 is a-central longitudinal section equipped with my improved dust proof self locking cover. mentary horizontal section on line b b, Fig. 1, through the journal box and my improved dust proof self locking cover, showing the cover closed and locked. Fig. 3 is a vertical transverse section on line 0 c Fig. 1, through the journal box showing an inside view of my dust proof self locking cover in locking position. Fig. 4 is a fragmentary view similar to Fig. 2 showing the cover almost closed. Fig. 5 isa detached inside view of my improved dust proof self locking cover. Fig. 6 is an enlarged detached end view of one of the latches. Fig. 7 is a fragmentary section through the journalbox on line a a Fig. 3,

showing my improved dust-proof-self locking Fig.2 is an enlarged frag constitute a seat for a cover or hinged to the box.

A lug 4, projects upward from the box and constitutes one member of the connecting hinge, and the cover or lid is formed with an enlarged bulged portion 5, at one end providlid 3, which is mg a space or chamber 6 in which the lug 4,

fits. the bulged portion are enlarged and provided with openings or eyes 8, constituting the other members of the hinge.

The upper portions 7, on the sides of The hinge members are pivoted -together by a pintle 9, which is secured in placebears 9against h g, hesnrfaceof- 80v 'whiclfisffiatteiied on two sides as at 13 and 14, in'Figs. 1 and 7, to maintain the cover both open and shut with aspring tension.

' The cover is provided with a seat 15 having bothsides provided with flanges 16 between whichjthe mar inal seat 2 of the car journal box' is a'dapte to fit to form a tight joint when the'cover is closed. The seat 15 extends entirely around the cover; the bulged portion of the cover being spanned by a bridge piece 17, see Fig. 1.

The cover when closed is locked in place with a sprin tension by means of a latching device attacied to the cover which engages lugs on the interior of the box and not only serves as a locking devicebut also automatically centers thecover with respect to the box as it is closed.

Thepreferred construction of the latching. device 1s shown in Figs. '2, 3, 4 and 5, espe, cially Fi 5, and consists of two opposed latches w rich are supported at opposite ends of a spiral spring.

The latches are of similar form each comprising a bar 18 of circular cross section having a pointed and beveled outer latching end 19 and a flange member 20 located at an intermediate portion of the bar, as shown in Fig. 2. The bar 18 and flange 20 are preferably cast integral to absolutely prevent inde endent movement of one or the other.

The latches are slidably supported in openings in lugs 21 on the inner. surface of the cover, wit a spiral spring 22, between them, which projects over the inner ends of the latches and bears against the inner surfaces of the flange members 20.

That portion of the edge of the flange members in contact with the inner surface'of the cover is flattened as shown at 23 in Fig. 6 to prevent rotation of the latches, and also support 1 them in their sliding movement. Tapered lugs 24 are formed on the inner surface of the opposite side walls of the box, see Fig. 2, against which the beveled ends 19 of the latches impinge while the cover is being closed, being pressed intoclose contact by the central spiral spring 22 and serving to center the cover with respect to the box so that it will seat perfectly thereon. By this a middle approximately V v 25, located between means the cover'when closed is s rin locked in place by an independent spring atchingdevice and held securely against rattling or movement. This also renders the cover practically dust roof. The latching evice is located in a horizontal position about midway of the cover and not only looks the .cover in place but also serves to prevent lateral movement of the cover when closed. The lacin of the latching device upon the mid e of t e interior of the cover raises it above the oil-saturated waste with which the filled and thereby obviates any clogging of the latches. Probably the most important advantage is that-the cover is centered automatically as it is closed upon the box so that it is seated perfectly thereon.

While the latching device is shown attached, to an. intermediate portion of the cover, it is possible to locate the same at other oints and still obtain the-same result.

In ig. 8 a fragment of another form of interlocldng seam between the: cover and box is shown m which the cover is provided with shaped depending enlar ement flan e its side anges which fits into a V shaped oove in .the seat, on the ear .ournal box. or localities that 'are. especial ly' sandy'or dusty this form of seam would probably be preferred asit is about as dust proof as it is possible to make.

The margin of the opening in the box is preferably chilled to render its 7 surface smooth and even and thus form a better and more perfect seat for the cover.

I claim as my invention- '1. In a car journal box, the combination with a box having inwardly extending lugs,

journal box is usuallyof a cover for said box and a latching device attached to about midway of the interior of the cover and havin spring-pressed latches tomatically locked and centered withrespect to said box.

2. In a car journal box, the combination with a box having inwardly extending lugs, of a cover for said box and a latching device for securing the cover to said box consisting of a spring and two opposed latches mounted at the opposite ends of said spring and adapted to engage the inwardly extending lugs whereby the cover is automatically locked and'centered with res ect to the box.

3. In a car'journal box, the combination with a box having interior lugs on opposite sides thereof, of a cover for said box and a latching device attached to about midway of the interior of the cover and having oppositely tensioned spring-latches adapted to engage the interior ugs of the cover when said cover is closed whereby the cover is automatically to the box.

4. In a car journal box, the combination with a box, a cover for said box and a cover spring, of. a latching device for securing the cover to said box which is entirely mdebox when the cover is c osed whereby the centered and locked with respect apted to engage o posite sides of the cover is automatically centered with respect to the box as itis closed.

, 5. In a car journal box, the combination with a box havin provided with inc ed surfaces, of a cover or said box and a latching device attached to the interior'of the cover and having springpressed latches thejends of which are pro- 'vided with inclined surfaces adapted to impin e ,and'. slide upon the inclined surfaces of t e lugs as the cover is closed whereby the cover is automatically centered as -it is closed.

6. In a car' journal box, the combination with a box, having interior lugs on opposite sides thereof of a cover for said box, e e lugs extending from the inner surface of t 6 cover, two 0 posed latches each slidably. mounted in t e eye of one of the lugs and having-flange members and as ir'al spring between the latches bearing .wit site ends against the flang'emembers.
