Claims.
This invention pertains to a journal box lid and more particularly to a type thereof which is mounted for pivotal movement about a journal box hinge lug.
An object of the present invention is the provision of a bearing block or slipper rotatably as-. sociated with a spring and so arranged andconstructed that as the bearing surface of the slip-- per wears during service, the slipper may be ro tated about its axis to present another unworn surface for contact with a journal box lug.
A further object ofthe present invention is the provision of an elongated, rectangular slipper rotatably mounted on a loop of a journal box lid spring with the slipper presenting angularly disposed surfaces to be selectively in contact with faces of a journal box hinge lug to hold the lid in open or closed position.
The above and numerous other objects of the invention will become apparent to those skilled in the art to which this invention appertains by reference to the accompanying drawing which illustrates an exemplification of the invention and wherein:
Figure 1 is a front elevational view of a journal box lid embodying the present invention.
Figure 2 is a vertical sectional view taken along the line 22 of Figure l and looking in the direction of the arrows.
Figure 3 is a horizontal sectional view taken along the lines 3-.3 of Figure 1 looking in the direction of the arrows.
By now referring to the various figures of the drawing wherein like reference characters indicate like parts the numeral l is employed to indicate, in a somewhat general manner, a journal box lid pivotally mounted on a journal box 2 about a pintle 3 in order to close or expose an access opening 4 of the journal box. As will be understood by hos lle i he ar the ac opening is formed in the journal box for the insertion or removal of a bearing brass and lubrieating retainer, none of which is illustrated and further so that the components of the interior of the journal box may be inspected periodically. The journal box lid is primarily a shiftable component adapted and arrangedto prevent the ingress of foreign substance to the interior of the journal box and thereby provide a tight, weatherproof seal at the access opening.
The journal box is made up, primarily of boxlike formation having walls 5 defining the access opening. The roof or top wall 5a of the journal box has, adjacent a leading edge thereof, a hinge lug shaving an axial bore or cylindrie cal hole 7 extending entirely therethrough trans- 2 versely of the box and spaced a predetermined distance above the top wall. Also, as is usual in hinge lugs of the type under consideration, the hinge lug is provided, intermediate its ends, with a front or forward face 8 somewhat vertically disposed and which, through a graceful curved corner 9, merges or blends into a top or upper face 16 somewhat horizontally disposed. These faces function as bearing or holding faces hereinafter brought out more in detail. I
The journal box lid is preferably, for the purpose of illustration only, of a so-called two-piece type and as such is made up of a cover H and a hood l2. The cover is a plate-like formation of an extent or area sufficient to blanket the access opening. The cover is suitably ribbed and flanged to strengthen the cover against stresses to which it will be subjected in service and provide protective skirting to function as bafiies or barriers against foreign substance directed toward the cover-box juncture in service. Further, the cover has a centrally arranged recess of spherical formation l3 to inset or depress the cover at a central region for the accommodation of related structure.
The hood, formed as a separate component from the cover, is provided with an upper ex,- tremity [4 of hollow cage-like design and open-v ing toward the journal box to overlay and house at least a forward portion of the hinge lug. The hood upper extremity has oppositely extending ears l5 suitably reinforced and apertured as at It to accommodate the pintle or hinge pin 3. This hinge pin, projecting through and beyond the hinge lug axial bore, functions as the sole connecting medium through which the journal box lid is pivotally connected to the journal box. A lower extremity of the hood has an outwardy p n .cu s a e or sp i a y di pos formation 1 ad n h ce tral ower or i thereof and this formation is spaced a predetermined distance outwardly of or away from the cover recess and preferably concentric therewith so that, within certain limits no interference between the cover proper and'hood will take place in this'r'egion.
Associated with the cover is 'a bridge member i9 having legs 26 directed toward and secured to the cover proper by means of welds 2! or any other desired means. As viewed in the drawing, the bridge member embraces the hood spherical: 1y sposed forma i n o a o inter o k fl xib the hood with the cover at this juncture. Ac-
cor ins e br dg m e i a s p ovided h a n b or s h rical is o e r e .2 a ranged to be accommodated by the hood spherical formation and thus a universal movement is provided for between the hood and cover. This is believed essential because the lid is pivoted about the hinge pin 3 and some means of equalization is necessary between the hood and cover to allow for manufacturing tolerances and assure a full seating of the cover on the journal box over the access opening.
Among the causes of journal box lid failure is the fact that certain related parts of the lid and journal box being subjected to wear after assembly and during service, wear to such an extent that the pressure value of the cover against the journal box is materially reduced. This subsequently worn condition then allows external impulses imparted to the journal box, to bounce the lid away from the journalbox further allowing, if only momentarily, the access opening to be uncovered and the ingress of foreign particles of matter to the interior of the journal box in defeat of the purpose for which the journal box lid is employed. Provision is made in the instant structure to correct this condition without subsequently adding any other components to the lid assemblage. Many thoughts present themselves toward the solution of the problem of subsequent wear; however, the preferred structure involves, in part, the use of a common type of resilient means improved to take care of difficulties arising from subsequent wearing of parts.
The lid assemblage includes a spring means 23 comprising a pair of coils 24 cradled in a curved spring seat 25 in the hood so as to retain the coils in a fixed position relative to the hood. Each coil has an outer downstanding leg 26 extending to a horizontal position in substantial alignment with what might be considered the center of the mating spherically disposed formation IS and spherically disposed recess 22 where such legs terminate in angularly directed feet 21. Lower portions of the legs and the feet are contained in suitable grooves 21a in the cover proper so that the downstanding legs are capable of urging the cover toward the journal box at all times.
The spring coils are further provided with an upstanding continuous or uninterrupted loop 28 which is bowed outwardly laterally along the axis of the coils so that a top bar 29 of the loop is of a length greater than the horizontal clear distance between the coils as clearly illustrated in Figure 1 of the drawing. Mounted upon the loop bar is a slipper or hearing block 30 which is rectangular in formation both in elevation and in cross-section. This slipper which is rotatably or pivotally mounted on the loop bar presents a plurality of surfaces 3| which are selectively arranged to bear alternately or selectively against the lug faces 8 or I!) to hold the lid in closed or open position. Accordingly, when the surface 3| which is illustrated in bearing relation with the lug face 8, because of repeated sliding actions across the faces 8 and I0, wears to such an extent that the predetermined pressure of the cover against the journal box is decreased beyond a required degree, the slipper may then be rotated through an arc of ninety degrees to present a new or unworn surface of the slipper for contact with the hinge lug. The surfaces of the slipper may, if desired, be all equidistant from the slippers axis of rotation about the loop bar; however, it is preferred to establish the surface am a fixed distance from the axis of rotation and possibly the surf-ace 3Ib positioned at an equal distance. The surfaces 3lc may be spaced a slightly greater distance from the axis of rotation because it is to be remembered that as the surface 3|a wears with continued sliding action over the faces 8 and [0 these latter faces are also wearing down and by positioning the surfaces 3 le as above indicated, this disposition will compensate for wear of the journal box lug surfaces and establish, even after wear, the predetermined pressure value of the cover against the journal box.
From the above, it will be noted that various changes and alterations may be made to the illustrated and described construction without departing from the spirit of this invention or scope of the appended claims.
