' This invention pertains to a journal box lid for closing the opening at the front end of a railway journal box. I

' It is an object of the invention to construct a two-piece journal box lid retaining all of the advantages of previous lids and which is considerably less expensive to produce. Contributing to the reduction in the cost of producing the lid is the elimination of all machining operations from the parts. Moreover, the parts are so arranged that a coil spring can be used which is not bent and ground flat on the ends, thus saving the cost of this grinding operation.

Another advantage of the invention is that the closure part of the lid can not become displaced from the housing, even though the spring that normally maintains the parts in assembled relation is broken and even though the spring may be broken into pieces small enough that they become lost from the lid. Means is also provided for maintaining the closure part of the lid in such relation to the mouth of the journal box opening .that the closure will return to the same position on the mouth opening at successive openings and closings of the lid. r u

Other objects and advantages of the invention will be understood from the following detailed description, taken in conjunction with the drawings, in which:

. Figure l is a side elevation of a journal box lid embodying the invention, applied to a journal box.

In the drawings the journal box ID has the usual hinge lug llv formed with an opening to receive the hinge pin M which joins the lid to the journal box. I The two-part lid comprises'a housing l2 having openings 13 therein for receiving 8 Claims. (Cl. 308-47) the hinge pin l4. At the lower end of the housing is an outwardly extending spherical protuberance 15 with flanges IG'and H on either side thereof, The closure member I8 is formed'with a U-shaped yoke l9 extending outwardly from the closure member. On the inner side of member I!) is a spherical socket adapted to receive the spherical protuberance IE onthe housing. member to form a pivotal connection betweenthe closure and housing members. On either side of socket 2B and adjacent flanges l6 and I1 the yoke I9 is formed with flanges 2| and 22 which serve to limit pivotal movement of the closure member in the plane of the journal box opening and also limit longitudinal movement of the closure member relative to the housing.

On the inner wall of housing member I2 is a .spherical socket 23 adapted to receive a ball pro,-

jection 24 of springlever 25 for pivoting thelever on the housing member. The upper end 26 of the lever engages forward surface 21 of hinge lug II in the usual manner. 'The lower end of the lever is formed with a pocket 28 adapted to receive one end of spring 29. Closure member I8 is depressed v "inwardly at its central portion to form a pocket 30 receiving the other end of spring 29.

.It has been customary in previous journal box lids of this type to bend and grind the ends of the coil spring fiat. However, this resulted in a loss of the use of approximately one-half of a coil at each end of the spring. In the present lid by using a coil spring with unbent and unground ends, the material is used more efficiently since the two ends by being left unbent and unground,

have the result of increasing by approximately one the number of efiective coils in the spring.

Thus with a spring of this construction the travel from free height to solid height is greater than with a spring of equal free height in which the ends have been bent and ground flat.

To provide some stability to the spring when it is in operating position bottom wall 33 of pocket 30 is sloped relative to the center line of the spring so that a portion of the bottom coil is in contact Likewise wall 34 of pocket 28 is sloped to provide some contact with the opposite end of the spring. Abutments 31 and 38.,are formed in

pockets

28 and 30 respectively to engage the ends of the coils of the spring and prevent rotation thereof about its longitudinal axis. These abutments are formed by sloping

projections

35 and 36 which projections are spaced from the adjacent coils of the spring so that there is no contact therebetween during normal operaftion of the device. I ,Thus withthe arrangement means is not provided to prevent loss of the 010-. a sure member from the lid when a spring breaks.

Loss of the closure member would permitdirtanjd moisture to enter the box andcontaminate. the

oil and thereby damagingflthebearing. the

present invention the housing, closure member.

and the lever are held in operative relation solely by means of spring 29. By theuse of a coil spring with unbent and unground ends sufiicient yoke and lever.

jfrgmjthe closure member and then gradually 4 ficient amount to permit the lower. end of lever to be placed on the outer end of the spring. The lever and spring are then forced toward the closure member until the springis compressed to its solid height, When in this position there is sufficient room between theouter surface of the lever andthe inner surface of yoke I9 to slide flange ll of the housingm'ember between the During this step in the assembly, the upper end of the housing is tipped away swung toward the closure member as flange l1 .,and;ba ;1l;;-i5 progressively slide between the yoke and thehpo'oketisfi. of the lever. When flange I1 initial compression can be placed on the spring within the space limitations present, that break age of a ,single coil wi1lnot 'elimina,te all of the initial compression of the spring. Moreover,;even though the spring breaks -'se ver al pieces allowing the housing member to move toward the closure member; flange; i i will prevent the closure member from ,dropping downwardly relative to the housing. In the event of breakage of the spring to such an extent thatjthereis no initial compression remaining, the-lever and housing 'wi'llmo'veby gravity toward the closuremember, since the lid as a whole is at an angleto the vertical. Even if the leverandhousing were to move toward the closure until-the bottom end of the lever contacted: the adjacent surface of I the closure memben'flange i I wouldstillbe in 'o'verlap-' pingrelationto flange 22 of the closure-member, thus preventing-the latter from moving downwardly and falling ofi'of the journal box.
