At the upper end of the frame l is a pair of resilient hinge eyes lb, preferably formed of resilient metal bent to such shape that the axes of the eyes lb are normally slightly offset outwardly from the axes of the bore J2 of the hinge lug J whereby when the hinge pin 2 is passed through the eyes lb and through the bore J 2 of hinge lug J theV sheet metal eyes lb will be deilected so as to forcibly pull the upper portion of the frame l towards and against the upper port of the opening in the journal box J, the action of the eyes lb and the resilient tongue la thereby serving to tightly clamp the upper and lower ends of frame l against and across the opening in the journal box J.
In order that the hinge pin 2 may be entered from either side of the hinge lug J' and will lock itself in place, the eyes Ib of frame l are preferably split as shown more particularly in Fig. 2, and the outer portions lbx `are crimped inwardly to engage annular grooves 2a in the pin 2 under the portions lb to prevent the pin 2 from normally shifting axially of the hinge bore J2.
As shown, the inner face of frame I is provided with a peripheral groove Ic (Figs. 1 land 3) adapted to hold therein a gasket 3 of substantial thickness, Ypreferably formed of oil-resistant neoprene or the like, adapted to contact squarely the lip around the opening of the journal box J, so` as to form an eiective seal, as indicated in Figs. 1 and 3. Due to the hinges Ib, Ibm, and the tongue la, the gasket 3 is seated firmly at all times against the lip of the opening of the journal box J, to prevent passage of dust and moisture therepast.
At the upper end of frame l are a pair of spaced outwardly rolled eyes le adapted to receive a hinge pin 4 for a, cover plate 5. Cover plate 5 is provided at its upper end with rolled eyes 5e (Figs. l, 2 and 3) adapted to engage the hinge Ipin 4, the outer ends of'the eyes 5e being of reduced width and extending beyond the ends of;thei;pin 4, and being flanged or bent over the ends gofpinli, after the latter has been inserted in place; ito': hold pin 4 in such position.

:The :journal boxlid willseal the journal box face -so .as to maintain same dust and moistureproof-.fevenif the hinge lug flats of the journal box are 'worn entirely away, since my arrangement A,doesrnotfusethese hingelugats on the journal :box casting although the coverplate 5 opens and v .closesinqthe conventional manner. The `gaskets Brand-6 Vmay beof oil-resistant neoprene or .the like, while the cover may be of steel and may be manufactured vreadily by a stamping process.
.I do'rnot limit myV invention to the exact form shown in the drawings, for obviously changes may be made therein within the scope of the claims.

The pressure on the 5. In a combination as set `forth in claim 1, said frame maintaining means comprising hinge eyes on the frame at opposite sides of the rst hinge lug and secured to the upper end of the frame by resilient metal straps, the eyes being normally offset from the frame la distance less than the actual distance of the upper end of the frame from the axis of the hinge pin, whereby the straps will be flexed when the hinge pin passes through the eyes, to forcibly draw the upper end oi the frame towards the box.
S. In a combination-as set forth in claim l, said frame maintaining means comprising hinge eyes on the frame at opposite sides of the first hinge lug and secured to the upper end of the frame by resilient metal straps, the eyes being normally offset from the frame a vdistance less than the actual distance of the upper end f the frame from the axis of the hinge pin, whereby the strapsv will be flexed when the hinge pin passes through the eyes, to forcibly draw the upper end o the frame toward the box, said eyes being transversely split, and having crimped portions at one side of the split engaging underlying annular recesses in the hinge pin.
7. In combination with a journal box or the like, having a bottom wall sloping upwardly and outwardly and terminating at an opening in the outer end'thereof, a hinge lug on the top of the box; a hinge pin in said lug; a lock seal lid, comprising a frame hinged on said pin and having an opening therein corresponding in area with the box opening; a gasket around the inner face of the frame adapted to engage the end of the box around said opening; means for maintaining the frame in tight contact with the box end; a second hinge pin mounted on the outer face of the frame adjacent the top thereof; a cover plate hinged on the second pin and adapted to overlie the frame; a second gasket around the inner face of the cover plate projecting beyond said inner face and adapted to contact the outer face of the frame; a pair of cams mounted on the frame projecting outwardly of the hinge lug Iof the journal box; rollers journaled in the outer ends of the cams; and resilient means on the cover plate yieldably constantly engaging the cams for exerting pressure for locking the cover plate in tight contact with the frame when the cover plate is closed and for exerting pressure for holding the cover plate in open position when the cover plate is opened, said pressure diminishing to zero when the cover plate is approximately half open or half closed.
8. In a combination as set forth in claim 7, each cam having a bore through which the second hing@r pin passes and serving as a bearing for the second hinge pin.
9. In a combination as set forth in claim 7, said resilient means comprising a Y-shaped` member having a base plate secured to the cover plate and having parallel leg portions offset from the plane of the base plate contacting the said rollers, the sides of the leg portions adjacent the rollers being iianged for the purpose of locally stiffening the same.
10. In a combination as set forth in claim 7, said frame maintaining means comprising a downwardly and inwardly inclined resilient tongue at the lower end of the frame adapted to enter the box opening and to contact the inclined bottom wall of the box adjacent the opening, to maintain the lower end of the frame in tight contact with the end of the box.
11. Ina combination as set forth in claim 7, said frame maintaining means comprising hinge eyes on the frame at opposite sides of the first hinge lug and secured to the upper end of the frame by resilient metal straps, the eyesbeing normally offset from the frame adistance less than the actual distance of the upper lend of the frame from the axis of the hinge pin, whereby the straps will be flexed when the hinge pin passes through the eyes, to forcibly draw the upper end of the frame towards the box. r
12. In a combination as set forth in claim 7, said frame maintaining means comprising hinge eyes on the frame at opposite sides of the rst hinge lug and secured to the upper end of the frame by resilient metal straps, the eyes being normally offset from the frame a distance less than the actual distance of the upper end of the frame from the axis of the hinge pin, whereby thejstraps will be fiexed when the hinge pin passes through the eyes, to forcibly draw the upper end of the frame towards the box, said eyes being transversely split, and having crimped portions at one side of the split engaging underlying annular recesses in the hinge pin.
13. A lock-seal lid, comprising a frame having hinge eyes at its upper end and having an opening therein; a gasket around the inner face of the frame, a downwardly inclined resilient tongue at the lower end of the frame; a hinge pin mounted on the outer face of the frame adjacent the top thereof; a cover plate hinged on the said pin and adapted to overlie theframe; a second gasket around the inner face of the cover plate projecting beyond saidw inner face and adapted to contact the outer face of the frame; a pair of cams mounted in the frame projecting outwardly of the hinge pin, rollers journaled in the outer ends of the cams; and resilient means on the cover plate in tight contact with the rollers when the cover plate is closed and for exerting pressure for holding the cover plate in open position when the cover plate is opened, said pressure diminishing to Zero when the cover plate is approximately *half open or half closed.
14. In a device as set forth in claim 13, each cam having a bore through which the hinge pin passes and serving as a bearing forthe hinge pin.
15. In a device as set forth in claim 13, said resilient means comprising a Y-shaped member having a base plate vsecured to the cover plate and having parallel leg portions offset from the plane of the base plate contacting the said rollers, the sides of the leg portions adjacent the rollers being flanged for the purpose of locally stifening the same.
16. In a device as set forth in claim 13, said hinge eyes being secured to the upper end of the frame by resilient metal straps.
17.`In a device as set forth in claim 13,'said eyes being transversely split, and having crimped portions atone side of the split.
