5 Giain 1s. (Cl. 308-52) This invention relates to articulated closure lid structures for railway journal boxes, and more particularly to' an improved hinge pintle retention means therefor.

More specifically, the invention has reference to a lid-supporting hood and a hinge pintle therefor, forming parts of structures asafore said, the object of the invention being to provide means formed integrally with the hood. and the pintle which co-act not only to prevent lateral displacement of the pintle but also to prevent rotation thereof.

The present invention has particular application to conventional closure lid structures wherein the lid-supporting hood isconstituted by a sheet metal stamping. Thus, it follows that the pintle-receiving apertures formed in the side walls of the conventional hood, present very narrow bearing surfaces to the hinge pintle which wear rapidly in use, when the pintle is not restrained against relative rotation, and neces sitates the frequent replacement of such hoods and pintles.

By means of the present invention, relative rotation of the hinge pintle in the apertures provided therefor in the lid-supporting hood is ob-- viatedsimultaneously with the retention of the pintle against lateral displacement. Consequently, when the lid structure is moved from closed to full open position relative to the journal Fig. 5 is afragmentary sectional view showing only the unheaded end of the pintle associated with the hood;

Fig. 6 is a fragmentary perspective view illuse' trating another modification of the invention; and

Fig. '7 is a view, similar to Fig. 3, of the modification of Fig. 6. V

Referring to the drawings, a lid-supporting hood It constituted by a stamped sheet" metal member, comprises side walls l! provided, adjacent their upper ends, with rearwardly extend ing ears 12 having aligned apertures l3-l4 for the reception of a hinge" pintle lfi'in conventional manner. The hinge-pintle connects "the hood to the cam lug E5 of a'journal box. The remainder of the journal boX, the box lid, torsion spring and hood-lid connecting means have been omitted from the drawings.

In accordance with. the invention, the ear [2 of the right side wall H is provided with an upwardly extending continuation or extension thereof, shown in dot-dash lines in Figs. 1 and 2', adjacent the pintle-receiving aperture i3 theree in, to form an integral tang or tongue l'l adapted to be initially bent 90 as shown in Fig; 11 and thereafter, after the pintle [5 has been disposed in the apertures l3l4 and cam lug Hi, to be box, the hinge pintle will move with the hood 7 and, when subjected to vibration and shock, will not rattle, oscillate or rotate relative'to the hood. Thus, the pintle-receiving aperturesprovided in the hood are not subject to wear, and replace ment of the hood and pintle is obviated.

Referring to the drawings forming a part of this application, wherein only enough of the structure of the journal'box and lid therefor are shown to illustrate the present invention:

Fig. 1 is a fragmentary front view, in elevation, showing only a portion of the hood and journal boxcam lug with a hinge pintle in assembledrelation therewith, the pintle retention means being shown preparatory to being bent into co-acting relation with the head of the pintle;

Fig. 2 is a side view inelevation showing only the hood in closedposition with the hinge pintle retention means bent into final co-acting relation with the head end of the pintle;

Fig. 3 is a fragmentary sectional view taken substantially on theline III-III of Fig. 2;

Fig. 4 is a fragmentary view, similar to Fig. 2, Showing a modifiedformof pintle head; 7

bent another. upon itself in depending sp'ace'd parallel relationwith the adjacent side wan] l, as shownin Figs. 2-3. The tongue IT is formed from waste metal, that is, from metal which would otherwise have been sheared off in stamping the right ear I2; It can be bent from the the aperture is" which is augmented by the addi tional support afforded by the bent tongue H- Further, in accordance with the invention, the hinge pintle 45 consists of a cylindrical body 19 having, at one end thereof, a fiat rectangular head 2'6, which, when disposedin assembled relaf tion in abutment with the adjacent sidewall ll, is disposed directly under the tongue Il -in suchclose relation to the root of the'tonguethat the pintle head 20 will serve substantially as an anvil upon which the tongue [l isbent down wardly, as aforesaid, in overlapping relation with the head 20. This arrangement assures the formation of a bend 2i at the root of the tongue it having a substantially uniform radius wbere by fracture of the metal at the bend 2| will not occur. The tongue I! has a base 22 which is considerably longerthan its outer edge 23, therefore assuring that the tongue I! cannot be battered from the hood. The cold bending and hammering of the tongue strengthens it, and the bent tongue strengthens the right ear l2.

As clearly shown in Fig. 2, after the tongue I! has been brought into co-operative engagement with the outer face of the pintle head 20, the pintle will not only be retained against lateral displacement and hammering, but will also be restrained against rotation relative to the hood H] by virtue of the abutment which the bend 2| of th tongue [1 forms across the path of the head 20 in contiguous relation thereto whereby the corner portions 24 of the head 20, for example, are adapted to be engaged by the abutment and relative rotation of the pintle l5 prevented. The pintle [5 can be formed of low cost cylindrical bar stock. It fits with working clearance only in the apertures I3 and [4, providing a long-lifed hinge connection. The pintle is adapted to rotate with the lid structure relative to the box lug I6. Therefore wear can occur only at the contacting portions of the cam lug and pintle body [9 and this is prevented in a conventional manner forming no part of the present invention.

Referring to .the modification shown in Fig. 4, K

the arrangement here is identical with that shown in the preceding figures with the exception that the head 20 of the pintle I5 is of flat cam-shaped configuration whereby the peak 25 of the cam head 20' will engage the underside of the bent portion 2| of the tongue l1 and prevent rotation thereof relative to the hood l.

It has been found that when the hinge pintle I is not restrained against relative rotation and is subjected to vibration, the direction of relative rotation is always clockwise or in the direction of the arrow indicated in Fig. 4. Similarly, upon movement of the lid structure from closed to full open position, the hinge pintle l5 may also rotate in a clockwise direction in response to such angular movement of the hood H1, or, if the pintle I5 remains stationary, it will be in its proper position upon closure of the lid structure.

In view of this condition, a pintle fiat faced head need not necessarily be rectangular, as in Fig. 2, but may be of any other configuration provided that a portion thereof extends radially thereof sufficiently to engage the abutment of the underside of the bent portion 2| of the tongue [1' whereby relative rotation of the pintle is prevented.

Figs. 6-7 illustrate another embodiment of the invention wherein the base of the tongue I1" is reinforced to give it longer life. The tongue I1" is substantially of the same shape as the tongue I! but at its forward side 26 it merges with an integral extension 21 which is also formed of wast material which would otherwise be sheared from the ear [2". Thus the tongue I1" has an outer edge 23" of the same length as the edge 23 but, has a base 22" about twice as long as the outer edge 23". Tongue I1 is, when in the position shown in Fig. 6, fiat and parallel to the adjacent edge of the pintle head 20" but extension 21 is curved upwardly from its juncture with tongue I1, this curvature adding to its strengthening characteristics.

In Fig. '7 it is clearly shown that the extension 21 extends from the adjacent side wall II" a distance about the same or slightly less than the outer face of the head 20 of the pintle 15'. Thus the extension 21 is not bent when the tongue 11" is bent from its position in Fig. 6 to its operative position in Fig. 7. However, any battering at the abutment 2|" is rendered harm'- less by the long connection between the tongue I1" and the side wall II" effected by the base 22' which base is in part integral with the tongue I1" and in part integral with the extension 21. Actual tests made in a vibratory machine have proven that the inclusion of the extension 21 more than doubles the life of the pintle retaining tongue.

The pintle I5 can be employed with the tongue I'l" if desired. The hood Ill will be shipped as shown in Fig. 6 so that it can be applied to a journal box and all that will be necessary from the mechanic's standpoint is the hammering down of the tongue 11" which will be effected in the same way as the hammering down of the tongue [1.

Fig. 5 illustrates the construction at the left side of the hood for all embodiments of the invention. Parts of the structures of Fig. 4 and of Figs. 6-? corresponding to like parts of the structure of Figs. 1-3 are indicated by like references with distinguishing accents added.

While there have been hereinbefore described approved embodiments of this invention, it will be understood that many and various changes and modifications in form, arrangement of parts and details of construction thereof may be made without departing from the spirit of the invention, and that all such changes and modifications as fall within the scope of the appended claims are contemplated as a part of this invention.
