construction of the lidtherefor andv means Vfor holding the lid open andrclosed.

Theparticular object of my invention is to provide a lid of the hinged type which will rest firmly on its seat all the way round and which will be held tightly to the seat, wherely the lid will form a dust-tight cover for the With these objects in viewthe invention relates to certain constructions and combinations of parts, the preferred form of which will be first particularly described and the invention pointed out in the claims.

Referring to thel drawings, wherein like parts are represented bythe same referencenumeral wherever they occur,Figure 1 is a side elevation of a journal-box, partly in section,

' lshowing my lid applied thereto. .Fig. 2 is a ing one of the ears by which the lid is pivoted to the box and the way in which it is pivoted. Fig. 4 is a view similar to Fig. 3, showing the lid in its open position. Fig. 5 is a detail view of the arm which holds the lid to its seat. Fig. 6 is a detached detail view of the ears of the lid. Fig. 7 is a detached detail view of the springs which actuate the arm lfor pressing the lid to its seat. Fig. 8 is aviewV similar to Fig. 1, showing the modified form of the means for holding the lid to its seat. Fig. 9 isa detailed view of the spring used in the lform of -construction shown in Fig. 8.

1 designates a journal-box of any, desired type provided with the usual opening in its front. The opening has a seat 2 round the same, on which the lid 3 is adapted to rest.

l 4 are a pair of ears suitably spaced apart, preferably formed integral with the box. Iv have shown these ears asextending up fromA the iop of the box; but it is to be understood that these ears can be placed at the side or sesamo. 149,368. ci@ man.)

bottom of the box without departing from my invention,

The lid 3 is provided with 'a pair of ears 5 5, preferably and as shown at the upper corners of the lid, and 6 is an elongatedo'pening passing through thel ears, by which the lid is pivoted to the box. ,The purpose of having this opening elongated will hereinafter' be described.

7 is a bolt `passing through the pair of ears lf'and 5 and on which the lid swings. As shown, this bolt is provided at one end with a head 8 and at'the other end with a slot through which the cott'er-pin 9 is passed tov holdv the bolt in position. It will be understood, however, that any other form of securing means might be used to hold the bolt in place.

Referringnow particularly to Figs. 1 to 7, inclusive, 10 designates a lever vwhichispro.- vided at one end with a head 1l, the head being cored out at 12, and in the side of this cored-out portion is located a longitudinal `slot 13. The endsof the head on the rear side thereof are cut away at 14 for a vpurpose which will be hereinafter described. .15 15 are a pair of springs having their free ends 16 17 in line vwith each other, as best shown vin Figs. 1 and 7. These springs are oppositely coiled, as there shown, so that when they are brought together, as shown in Figs.

ing in the same direction.

that they will tit the bolt 7, andthe outside diameter of the coils is such that they will yfreely pass into the opening 12 of the head k1l and form what is practically a bushing Yupon-which the head may turn.

bling the parts the springs are placed with In assemjection 18 is provided with suitable openings 2and"7, their inner ends 16vwill be adjacent j IOD 24, into which the outer ends 17 17 of the springs may be inserted.

19 19 are wedgeshaped lugs on the rear side of the ears 5 5 of the lid.

2O designates a cut-away groove in the upper corners of the box just below the face 21 on the top of the box. This construction is best shown in Figs. 3 and 4.

22 is a lug provided near the center of the lid 3 within the area of the seat under which the outer free end of the arm 10 engages.

When the device is assembled in the manner shown and described and the parts are in a position shown in Figs. 1 and 3, it will be seen that the tension of the springs 15, acting through the arm 10 on the lid, will, because of the elongated opening, tend to move the lid toward its seat, and consequently the rear end of the elongated slot will be moved away from the pivot-bolt 7, so that the parts will stand in substantially the position shown in Fig. 3. When now the lid is opened, the

springs 15 willtorce the rear end of the slot 6 away from the bolt 7 until the projection 19 comes in contact with the surface 21 and moves thereon, being held against the surface 21 by the springs 15 until the projections 19 are forced down into the cut-away portion 20, when the parts will be in the position shown in Fig. 4 and the lid will be held open against the tension of the springs 15. When it is desired to close the lid, it is only necessary to press downward on the free end of the lid hard enough to cause a camming action between the side of the projections 19 and the side of the cut-away portion 20, lifting the projections 19 out of the cut-away portions 20, and as soon as the projections 19 are clear of the cut-away portions 2O the springs 15 will force the lid down onto its seat. The elongated slots 6 are substantially vertical to the seat, and, besides allowing the motion above described for the purpose of bringing into action means for holding the lid open, perform two other very important functions, which are: they permit the lid to 'move freely toward and away from its seat without interference by the pivotbolt 7; hence when pressure is exerted on the center of the lid by the arm 9 then pressure will be equally distributed on the seat all around the seat, while at the same time the slot, being substantially horizontal, prevents vertical motion of the lid on the seat.

Referring to the modifications shown in Figs: 8 and 9, it will be noticed that I have dispensed with lever 10 andsubstituted therefora spring-arm 23, which is a partV of the spring 24. The rest of the construction shown in this modification is the same as that heretofore described. The spring 24 surrounds the bolt 7 in the manner previously described, and its free ends 25 pass through openings in the projection 18 on the box. The outer end of the spring-arm 23 is engaged under lug 22 on the lid in the same manner and fori the same purpose that the lever 2O engages this lug.

While I have described what I believe to be the preferred form of my invention, I desire to have it understood that many modifications and mechanical changes might be made therein without departing from the spirit of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a journal-boxhaving an opening provided with a seat, of a lid, provided with projections, hinged to the box, and a spring adapted to exert its pressure on the lid within the area of the seat to hold the lid to its seat, the projections being adapted to cooperate with the box to hold the lid open against the tension of the spring.

2. The combination with a journal-box having an opening provided with a seat, of a lid provided with elongated pivotal openings, a bolt carried by the box and passing through the elongated openings, a spring adapted to exert its pressure on the lid within the area of the seat and means carried by the lid adapted to cooperate with the box to hold the lid open against the tension of the spring.
