To all whom it may concern.- I

Be it known that I, GUSTAV A. FAITZ, a, citizen of the United States, and a resident of Chicago, Cook county, Illinois, have invented certain new and useful Im rovements in Car'- J ournal-Box Covers; and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying'drawin s, and to the letters of reference marked t ereon, which art of this s ecification.

This lnvention re ates to improvements in car-j ournal-box covers or car-axle boxes and is shown ap lied to a-journal-box of the Master Car-B ders type. I

Heretofore it has been diflicult to provide a j ourna l-b'ox cover adapted to facilitate inspection-of the contents of the journal-box for the purpose of supplying lubricant thereto or for purposes of repair, which, though permlttin such inspection, also acts to entirely 'exc ude dust, dirt, and cinders from finding access to the journal throu hthe outer end of the box. In many of t e devices heretofore constructed for the purpose the cover has not only permitted dirt-to find its way into the journal-box, but in many instances the covers are so attached to the box as to become readily detached, thus leaving the entire end of the box open. Many of such covers are so constructed also as to render inspection difficult, frequently requiring the expenditure of considerable time to open the box to complete the inspection and again close the box.

The object of this invention is to provide a cover construction adapted to be instantaneously opened and to remain supported in an open position during inspection and to be quickly closed, and when closed to absolutely exclude the entry of dust, dirt, or other objectionable material into the box.

The invention embraces many novel features; and it consists of the matters hereinafter described, and more fully pointed out and defined in the ap ended claims.- v

In the drawings, Figure 1 is a side elevation of a journal-box provided witha journalbox cover embodying my invention. Fig 2 is a front end elevation of the same. Fig. 3 is an enlarged'vertical fragmentary section of the end of the journal-box and cover, showing the same closed and showing in dotted. lines its open position. a Fig. 4 is a front elevation of the cover, showing the inner flange and the carrying-plate in dotted lines. Fig.

5 a bottom plan view of the cover embody mg move Fi 6 is a fragmentary view and is similar to t at shown in Fi 3, but illusmy invention with the carrying-plate re-.

trates a construction in whic thepintle is omitted. Fi 7 is a section taken on line Z 7 of Fi 6. ig. 8 is a central section of a slight y-modified construction of the connection between the'cover and the carryingplate.

Fig. 9 is a fragmentary top plan'view of the cover, showin the'stem connecting I the carrying-plate wit the cover in section.

As shown in said drawin s, A indicates a journalbox of the usual or aster Car-Builders type provided at its top and outer end with an outwardly and u wardly extended lug a, onwhich is pivotally supported the cover embracing my invent1on.- Said cover comprises a cover B of a size adapted to cover and overlap the sides and top and bottom of the open end of the journal-box and provided on its innerface with a flange b, which fits closely in the 0 en end of said journal-box and acts to hol said plate in register with said 0 ening. Said cover B may be of any desired material. As shown, however, and conveniently, the same is of malleable jron or other suitable metal and is provided, as

shown in Figs. 1 to 5, inclusive, on its outer face with a central ball-shaped depression, surrounded with a plurality of outwardlydirected prongs or projections 1), adapted to receive between the same and in said depression the ball-shaped head C of the pin 0, whereby the carrying-plate D is movably connected therewith. The points or projections 6 are closed down over the head 0 of said pin, afiording aball-and-socket joint, and said pin projects through an aperture in the carrying-plate D and is closed down thereon by riveting or in any suitable means permanently connecting the cover B with said carrying-plate D, though permitting considerable relative movement.

The can-ying-plate, as shown, is provided at its u per end with a recessed knuckle d, adapte to extend over the projection at on the box and is provided with a transverse aperture adapted to receive a pintle 0/, whereby the same is hinged to said projection. Said carrying-plate, as shown, is cored out to afford an interior recess for approximately its entire length, but which terminates near'the pin 0 in a pocket or recess adapted to receive the lower end of'a strong leaf-spring (1 The upper end of said spring bears upon the forwise provided at the to of the carrying-plate,

wardly-extended end of the rojection of a, the outer under side of whic affords a cam which holds the end of the leaf-spring under compression and sufiiciently beyond the hinge to jam the cover firmly against the open end of the box, thereby holding the cover firmly closed. The upper surface of said projection 01. on the box is also shaped to afford a cam-surface, so that when the cover is elevated, as shown in dotted lines in Figs. 3 and 6, the upper end of the leaf-spring lies along the top of the projection a, and supports the cover, leaving the end of the box open .for inspection or lubrication.

As shown, a vertical rib b is provided on each side of the center of the cover on the outer side and above the pin. Said ribs fit closely in the recess in the carrying-plate, as shown in dotted lines, Fig. 4, and act to hold the cover from turning on the pivotal connection between the same and the carr g-plate afforded by the pin 0. If preferre the connection of the coverand the carrying-plate may be afforded by means of a ball-shaped connecting member 0, provided with a pin 0 adapted for connection with the carryingplate, as before described, and the ball-shaped end of which may be inserted into the mold at the time the cover is cast, thereby permitting the same to be cast into the coverlate, as shown in Figs. 8 and 9, thus affording a permanent though flexible connection between the cover and the carryinglate. If preferred, the intle a may be omitted, and an inwardly-directed lug d is cast or otherand a downwardlydnc ed recess is provided each side of the projection 41, as shown in F g-J6, adapted to receive said lugs. With this construction .a shoulder 01 may conveniently be provided near the upper surface and Back of the projection a, against which the end of the leaf-spring d engages when the coveris elevated, as shown in Fig. 6, thus.

holding the cover-plate from being detached accidentally when the cover is raised.

The operation is as follows: The pressure of the s ring d on the forwardly-extending end of t e projection (1 acts to hold the cover either in its closed or its open osition. This will be seen from reference to ig. 3, in which the forwardly-extending point of said pro j ectionwfi a bears the upper end of the spring away from the ivot, bringing suficient tension thereon to orce the lower end of the carrying-plate, with the cover attached thereto, into bearing against the open end of the box. Should, however, the cover be elevated, the end of said spring engages alon the top of the projection a, the extende point thereof affording a support. The resistance of said spring is sufficient to support the cover in its open position.

Owing to the construction described it is obvious that when the coveris thrown down saaseo tion between the cover and the carryingplate being such as to aflord a ball-an socket ioint enables the cover to adapt itself perfect y to the opening in the journal-box independently of any slight variance in the point of ivotal attachment of the carrying plate wit the journal-box. Inasmuch, too, as the point of the connection of the carryinglate with the cover is at the center of the latter the pressure of thesprin s exerted equally in all directions on sai cover, acting to hold'the same firmlyin osition with equal pressure on all sides of t e boxopening.

I claim as my invention- 1. In a carournal-box cover adapted to entirely close the open end of the box, a cover-plate, a carrying-plate hinged to the box, means adapted to hold the cover-plate in register with the box comprising a recess in the under side of said car -plate, adapted to receive an outward yirected flange on the cover-plate and a ball carried on said carrying-plate, there being a socket on said coverlate adapted to c osely engage about sai ball.

2. In a cover for a journal-box, a coverplate provided with a continuous inner flange to fit within the 0 en end of the journal-box, a carrying. mem er on said box provided with a recess on its under side adapted to receive flanges on said cover-plate, a s ring in said recess adapted to normally hol the cover-plate closed, a pin rigidly e aged in said carryin member and provide with a ball-sha ed head, there bein means on the cover-p ate ada ted to close y engage over the top ofsaid all and together therewith form a ball-and-socket joint.

3. A car-journal-box cover comprising a cover-plate provided with an internal continuous flange adapted to fit closely in the open end of the box and positioned at a dis tance from the margin of the cover, a carrying-plate hing with de ending lateral flan es and a recess intermediate said flanges, t ere being integral outwardly-directe flanges on said coverplate adapted to engage in-the flan es on said 0 -plate an means flexiby engagin said plates together.

4. cover or car ourna oxes com HS- 2 f l b p .ing a cover-plate provided with a continuplate, there being a socket in said coverplate adapted to fit closely about, said ball and a spring carried beneath said carryingplate acting to hold the cover-plate in its open or closed osition.

5. A cover or car ournal-boxes comprismg a cover-plate havmg an mternal continu- Y ous flange on the inner side thereof adjacent its mar ada ted to fit within the journalbox an paralle flanges on the outer side of the cover-plate, on opposite sides of the center, a carryinglate hinged. on the journalbox and centra y on said cover-plate and having a recess therein adagited to receive and to secure said flanges an a spring actin to support the cover when open and to hol the same in position when closed.

-6. In a device of the class described the combination with a .journal box having a projection above the opening thereof provided with upper and lower cam-surfaces engage the upper cam-surface when in its uppermost position, a cover-plate and means providing a flexible joint between the same and the carryinglate.
