7 Claims. (01. t es-475* 1 This invention relates to hooded journal box covers of the articulated type in which the component elementsare assembled in relatively movable relation. to permit accurate fitting of the lid portion of the assembly to ensure complete closure of the journal box opening. r i More particularly, the present invention resides in the provision of an improved articulated cover assembly in which the design of the component elements, comprising the lid proper, the lid closing spring, and the hood or spring housing, is improved so that the assembly of these elements in interlocking relatively movable relation and the application of such assembly to the journal box is greatly facilitated.

A particular feature of the present invention resides in providing the lid and hood elements of the cover assembly with complementary apertured portions through which extensions of the lid closing spring are passed to form part ofthe fastening means by which the lower portions of the lid and hood are secured together in rela* tively movable relation. I

Another feature of the invention resides in the provision of novel fastening means between the hood and the upper portion of the lid which serves, in conjunction with the lid closing spring, to prevent complete separation of the component parts of the cover assembly during the relative movement which takes place between these parts when the lid is fitted to the journal box'and during movement of the lid to open or closed position. Other objects, characteristic features and advantages of this invention will be more readily understood from the following detailed description taken in connection with the accompanying drawings, in which I i Fig. 1 is a front elevation of an articulated cover assembly provided in accordance with this inven- Fig. 2 is a side elevation of the assembly appear- [ng in Fig. 1,with theexception of the lid closing spring which is omitted for the sake of clearness.

1 The articulatedcover assembly appearing in Figs'L-l to 6 inclusive comprisesa lid 11, a lid closing spring l2,-and ahood or spring housing 13.

- A pair of hooks l4'are cast integral with the upper edge of thelid 11 and project beyond the isprovided 'with recesses 15 and with a pair of integral lugs 16 located adjacent the inner sides 'ofthe' recesses; The front'wall of the hood 13. presents parallel-transversely curved portions 17 and '18 extending between the side walls '19,

which carry the integral pintle receiving sleeves -20an'd 2 1. Attheir lowerends the side walls 19 of the hood are shaped to provide substantially in a plane substantially parallel with the outer -surface of the lid 11 and have their upper ex;-

tremities' shaped to provide rounded portions 26 loosely fitted beneath the hooks 14.

The li'dclosing spring 12 is at'orsion spring-presen'ting' twd'coils' 27 and 2B connected by an in- I iterr'nediate U-shaped'portion 29 w'hich c0nsti-' "tutesan integral continuation of the inner'terminalconvolutions of the 'coil and carries a roller 30. The outer convolutions of the coils 27 and 28 are extendedto provide *a'pair of parallel side outer surface of the lidasshown to advantage in Figs. 2 and-3. The c'en'tral portion of the lid arms 31 having their lower ends bent outwardly at right angles to provide pin-like portions 32 which extend through the openings 24 of the lugs 16 and through the registering openings 23 formed in the eyelet members 22 of the hood. As shown to advantage in Fig. 3 the curved front Wall portion 18 of the hood serves as a fulcrum pocket in which the coils 27-and28 of the'lid closing spring are seated, the U-shaped portion 29 of the lid closing spring, together with the roller 30, being housed by the upper front wall portion 1'7 and the side walls 19 of the hood the recesses 15. Relative vertical movement of the lid and hood parallel with the front face of which also serve as a housing for thejournal box lug The manner in which the articulated cover a's-' sembly is applied to the journal box is "clearly shown in Fig. 3, in which 34 designates a journal box having the usual mouth opening and pintle' lug 36, the latter'being provided with the.

customary angularly related cam faces 3'7 and 38 adapted to co-operate with the roller 30 of the lid closing spring 12 to hold the lid in closed or open position. The pintle; receiving sleeves 20 and 21.:of the hood 13 are disposed at'opposite sides of the lug 36 and receive the ends'of the pintle 39 which passes loosely through said lug. In the present instance the outer endof the pine tle receiving sleeve 20 is shown partly closed by an annular flange 20' which providesan abutment for one end of the pintle 39, theother end of which is adapted to be engaged by one or more bent pintle retainingtongues provided at the outer end of a pintle retaining liner 41. fitted T in the pintle sleeve 21',saidpintle retaining liner then becomes effective to retain the lid liners 41 in both ofv the pintle sleeves of the hood resides in the fact that these liners take thewear of the pintle and may be replaced atva relatively small cost when unfit for further service. When the lid is in the closed position shown in Fig. 3 the roller 30 bears on the cam face 37.0f the lug 36 so that the spring 12 exerts pressure against the central portion of the lid :11 tohold-thelid firmly against the contacting surfaces vof the journal box surrounding the journal boxopening 3 5. .When the lid is raised to open position the roller 30 rides over the cam face 37 of the lug 36 and onto the cam face 38 so that the spring in its open position. l e v I The manner inwhich the lid 11 and the hood 13 are secured together in assembled relation permits these, parts to have a certain. freedom of relative sliding andangular movement which,

as. is wellunderstood in the art, is frequently :necessary in order to ensure proper fittingof the cover assembly to completely close the journal box opening in accordance with ;A.R.-A. requirevments relative to exclusion; of dust, water, etc. Inthis connection it will be noted that acertain amount .of clearance is reserved between the hooks 14of the lid and the co-operating rounded portions 26 of the hood; It will also be observed .that a certain amount of clearance isreserved .between 'theey'elet members 22 ofthe hood-and the side walls of the lid recesses 15in which these members areengaged.' ,Due'to this clearance .1. and to the mannerin which the eyelet members placed for assembly purposes.

22 of the hood are pivotally connected to the lugs 16 of the lid by the extensions 32 of the lid closing spring, it will be seen that the lid and hood are capable of what may be termed universal movement with respect to each other. Horizontal sliding movement of the lid and hood parallel with the front face of the journal box is permitted by reason of the sliding fit obtaining between the .lid hooks '14- and the co-operating rounded members 26 of the hood and by reason of the fact that the eyelet members 22 of the hood are free to have a limited lateral movement in the journal box is provided for by the reserva- .tion; of. a certain amount of clearance between the rounded members 26 of the hood and the -=overlying portions of the lid hooks 14 and by -,making the extensions 32 of the spring 12 slightly smaller than the openings 23 and 24 through .whichithey extend. The looseness of the upper connectionsbetween the hood and the lid as represented by the interengaging elements 14 and 26,. as well as .the looseness of the lower pivotal connections afiorded by the extensions 32 of the lid closing spring, provide for a certain relative angular; movement of the hood and lid in various. directions. I .JInFigs. 7 and 8, I have shown a modified cover assemblyin which each of the previously mentioned hooks 14 is replaced by a stud 43 cast integral withfthe outer face of the lid 11. This stud is passed through an opening formed in a lug 44 cast integral with the hood 13' and is made hollow at its outer end so that this end may then beiriveted over or upset to form a head 45. The clearance reserved between the head 45 and the lid 11 is. greater than the' thickness of the lug ;44 in order, to provide for relative movement between the lid and hood. The opening in the lug 44 through which the stud 43 passes is also preferably made larger than the stud in order. to provide for a certain relative movement of the lid and hood in'a vertical direction.

The further modification shownin Figs. 7 and 8 resides in the provision of two lugs 16 lying at opposite sides of the recess 15' in-which the eyelet 22 of the hood is fitted. These lugs 16 are connected together as at 16a to form a boxlike housing for the eyelet 22 and are both provided with openings registering with the openings'of the eyelet -.to receive the extensions 32 of the lid closing spring. The other parts appearing in Figs. 7 and 8 are the same'as described in connection with the preceding figures.

jIn thejfurther modification illustratedin Figs.

-9,to,11, each sidewall of the hood 13is provided with an integral outwardly projecting lug 46 loosely-fittedv in a housing 4'7 cast integral with the outer face of V the lid 11 so that these parts 46 and 47 perform substantially the same function as the parts 14 and 26 ofFig. 1 and the parts 43 and .44 of Figs. '7' and 8. As shown more particularly in Fig. 11, thelugs 46 are provided .with inclined surfaces 46a which enable these lugs. 46 to be sprung past the housing members 47 and into interlocking engagement therewith. In this connection ;it will be understood that there is suflicient 'spring in the side walls 19 of the hood to permit the lugs 46 to. be sprung past the closed outer end walls 47a of the casing 47 when pressure is applied through the agency of a suitable press in which the 1id and hood are In each: of the constructions described in the foregoing, the side walls 19 of the hood 13 may be provided with registering openings 19a for the reception of a spring retaining pin such as that forming part of the subject matter disclosed in my co-pending application Serial No. 642,065 filed Nov. 10, 1932.

In Fig. 12 there is shown a slight modification of the hooks 14 provided at the upper edge of the lid. In this case the hooks 14 are made of greater length as compared with Figs. 1 and 2 so that the free ends of the hooks may be bent inwardly from the dotted line to the full line position shown in Fig. 12 to engage beneath the co-operating members 26 of the lid. The advantage of this construction is that the portions of the members 14 extending beneath the co-operating members 26 will serve to hold the lid to the hood in case of failure of the pivotal connections afforded by the outwardly bent portions 32 of the spring arms 31.

In the modification shown in Fig. 13, the lower ends of the spring legs 31, instead of being bent outwardly to provide the portions 32 as previously described, are left straight and inserted in suitable sockets 31a cast integral with the outer face of the lid. In this case the lugs 16 of the lid may be pivotally connected with the eye members 22 of the hood by suitable rivets 32a, one of which appears in Fig. 13. These rivets 32a may, of course, be replaced by bolts or other suitable forms of pivotal connections that may be easily removed.

Having thus fully described what I now conceive to be the preferred embodiments of my invention, it will be understood that various other modifications may be resorted to within the scope and spirit of the appended claims.
