are connected. together by the rounded edge tion chea to manufacture and serviceable i p in opera-tion.

A further object of the invention is to provide a lid with means of simple construction for automatically and yieldingly holding the lid .in open and closed positions and so construct and arrange the parts of this means that they may be readily assembled and secured in place without the use of bolts, rivets or other permanent fastening devices.

@ther objects and advantages of my invention will be apparent as it is better understood `from the following description which, taken in connection with the accompanying' drawing, discloses one preferred embodiment thereof.

@n the drawing-h`igure 1 is a fragnien-` tary vertical sectional view of a journal box provided with a lid made in pursuance of niy invention; Fig. 2 is an enlarged vertical sectional view similar to Fig. 1 showing the internal construction of the follower; Fig. 3 ista sectional view on the line 3-3 of Fig. 1; lfig. t is an enlarged front elevation of the follower shown in Figs. 1, 2 and 3, and Fig. 5 is a partial vertical sectional view illustrating a modified forni of the lug and follower.

For the purpose of illustrating my invention l have shown a journal box 10 which may be of any preferred form or construction having the opening' 11 in its outer end and the lug 12 upon its upper wall 13. Through an aperture in the lug is positioned a pintle 1d upon which the lid 15 is pivotally mounted. The lug 12 is provided intermediate its ends with the upper inclined bearing face 17 and the front vertically disposed face 1S terminating in a shoulder 19 formed by providing a transversely extending groove or recess 20 in the front face of 5 the lug. The two bearing faces 17 and 18 21. A follower or upon the lid 15.

tremity of said being connected 27 formed integra the portion 26 and The housing 25 nally extending ting within the end inforced by a n blo cli enga face 23 adapted to 17 and 18 21 is located within a This SSIGNOR T0 KIRIBY EQUPMENT PORA'IION 0F ILLINIS.

22 having a bearing ge thc bearing faces and a shoulder 2d gage the shoulder 19 and the shaped to enrounded edge housing 25 formed housing elevated above the front surface of the lid 15 and incliued thereto, a portion the lid being forni the bottom of to the front wall of the of the front wall of inclined outwardly as at 26 to the said housing, the exontwardly inclined portion main part of the lid by means of the wall lly with the extremity of the main part of the wall. is preferably cast in a single piece with the lid and is so located with respect to the pivotal con lid and lug upon open end of the housinL bearing faces of positioned within the l lug by a coiled expansion urged aga-inst the erposed between nection between the 4the journal box that the g is opposed to the the lug. The follower 22 iousing is normally the follower and the front wallof the housing, the folprovided with a longitudicylindrieal projection 29 litof the coiled spring 28. To support the follower iii proper position l provide upon each side of the housing and extendinginwardly thereof the lianges or shelves 31, each of which is preferably re- Teb 32 and upon opposite sides of the follower are .formed lugs adapted to restupon these flanges 31.

For the ing surfaces to facilita closing movements provided with a core o oil which is inserted in device is assembled. inunicating with the c purpose of lubricating the bcarte the opening and of the lid the follower is i' recess 3ft adapted to receive a lubricating agent such as heavy grease or waste saturated with a lubricating the core before the in aperture 35 comore 34tpermits the lubricant to be distributed over the bearing faces 17, 18 and 23 of t respectively.

Tn the modified form of the housing 4l and the shown in Fig. 5

he lug and follower my invention spring l2 are substantially identical with the housing 25 and s in connection with Fig front wall of the lug lll pring 2S described s. 1, 2 and 3. The however is undercut to provide the shoulder 45, and the bearing face of the follower 4G which is formed substantially flat is provided at its upper l end with the shoulder 47. Then the lid is in closed position, as shown in Fig. the 5 shoulder 47 rests under and abuts against the shoulder l5 o f the lug, holding the lid in closed position and preventing apping and-jiggling of the lid in service. llVhen the cover is opened theV shoulder 47 is forced inwardly of the housing il against the force of the spring 42 by the shoulder 45 and the shoulder 4S formed at the lower edge of the follower moves up and yieldingly engages the shoulder 45 to retain the -lid in open position.

1t will be manifest that a lid equipped witha spring pressed follower in accordance with my invention will yieldingly retain the lid in both open and closed position, the

:resistance to movement of the lid afforded by theJ construction disclosed being dependent of course upon the force of the spring actuating the follower.

lt will 'be manifest also that various '-,\changes may be made in the form and construction of the parts and arrangements without departing from the spirit and scope of my invention, or sacrificing any of its advantages, the form hereinbefore disclosed being merely one preferred embodiment thereof.

1. The combination of a ournal box provided with a lug havinga flat face on its forward side and provided with a shoulder atit-s upper edge extending beyond saidflat face and provided also with a shoulder at its bottom located inwardly of said fiat face, a lid pivotally connected 'to said lug,

40 :fa follower carried by said lid and having a flat forward face terminating in a forwardly extending shoulder at its bottom and a rounded shoulder at its top, the faces and shoulders of the follower and lug being so 45,;arranged that the lower shoulder of the follower engages the inwardly disposed shoulder at the bottom of the lug and the rounded shoulder at the top of the follower engages beneath the outwardly eX- =tending shoulder of the lug when the lid is in closed position and the lower shoulder of the follower engages the outwardlyextending shoulder of the lug when the lid is in open osition and means yieldingly pressing 55.y `said follower against the lug.

.2. The combination of a journal box provided with a lug having a flat face terminating in shoulders at its upper and lower edges, a follower carried by the lid and hav- G0 ing a flat face adapted to contact with the said flat face of the lug and terminating in a shoulder at its lower edge adapted to engage the Said shouldersof the-lug, said flat faces and shoulders of the lugand follower being arranged to permit the flat face and lower shoulder of the lug to contact with the fiat face and shoulder of the lid when the latter is in closed position and permit the upper shoulder-of the lug and the shoulder of the lid to engage when the latter is in open posit-ion, and means for yieldingly pressing Said follower against said lug.

Tliecombination of a journal box having a lug formed thereon, a lid pivotally connected tosaid lug, and provided with an open ended housing having inwardly eX- tending shelves, a follower positioned `in said housing, and having outwardly extending lugsadapted to rest upon the said shelves to vsupport the said follower, and a spring normally pressing the said follower against the'said bearing lug whereby the lid is retained in open and closed position.

il. Thecombination of a journal box having a. lug formed thereon, said lug being provided with a plurality of bearing faces, a lid pivotally connected to said lug,a follower slidinglyimounted in said lid and provided witha bearing face adapted to engage the bearing facegof the lug, anda spring normally pressing the said follower against the said lug, said .follower being provide with a recess adapted to contain a lubricant, and having an aperture throughwhich the of the lug and follower.

5. The combination-of a journal box having a lug formed thereon, a lid ypivotally connected to said lug and provided with an open-ended housing, a follower positioned in said' housing, means extending inwardly of the housing and engaging the said follower for supporting the followerandgnid-1 ing it longitudinally of the housing, and means for pressing said follower against the 6. The combination of a journal box having a lug formed thereon, a lid ivotally connected to said lug and provi ed with an open-ended housing, a follower positioned in said housing and provided with oppositely extending supportinglugs enga ing said housing for supporting and guiding said followerlongitudinally of the housing,

andmeans for pressing` said follower against said lug.
