ToaZZ whom it may concern.-

Beit known that I, ALVIN C. MCCORD, a-

citizen'of the UnitedStates, residing at Chicago, county of Cook, and State of Illinois,

lhave invented certain new and .useful Im proveniente iu Car-Axle Boxes and Lids,which are fully' set forth in the following specification, reference being had ,to the accompanying drawings, forming a. part thereof.

In the drawings, Figure 1 is a sectionalv lfront elevationof my improved axle-box and lid, section being made at the plane indicated -by the line 1 1 on Fig. 2. Fig. 2 isa section atthe line 2 2 ou Fig. 1.

ner side elevation of the hinge endgof the cover. Fig. 4 is an elevation showing my im- Fig. 5 is a section at the line 5 5 on Fig. 4. Fig.

' 6 is a plan oa blank partly shaped up, showing a specific preferred construction of the lid Fig. 7 is au edge T he axle-box A is of ordinary construction points hereinafter described to receive my side of the box, midway in its Width, there is formed a boss or lug A' for vthe purpose of hinging the lid thereto. The lid is formed with a hood-like hollow boss B', erected mid way in iis width at` the upper part of its length and extending up far enough to cover the `boss A at theupper side. This hood'B .constitutes the housing for the spring C, and

side webs B10 B111 of the hood in the east form of my'inventiou afford the sup-port for the pivots pf the lid on the box, for from the inner surface of the webs 'B111 trunnions B11 B11 protrude inwardly, takingintothe pivotsockets A11 A11 in the opposite sides lof the boss A on'the box.' When this form is adopted, the hinge-trunnions B11 reach their seats in the piyotLsockets through the slots A10 A111, whichlead from thel rear side of the lug A' at the opposite edges, as clearly seen in Fig. 2'. The pivot-sockets A11 are elongated in the direction of the box-.face or seat of the lid on thebox, so ythat when the lid has its trunnions engaged in the sockets, respectively, and is resting opihe face of the box-opening it canv slide thereon a distance corresponding to the Fig. 3 is a detailin- `elougation of theI sockets, and the lid, at or which is adapted to passinto the box-opening and to engage the lower edge or lip A2 of that the inner sideof the lid back into the box,

lock the lid when it is seated. The boss A' at the opposite edges has the shoulders A A12 parallel with the face of the box-opening on which the lid seats, and the lid B 'has in the corners of the hood B' interior bosses or blocks B1, which form shoulders Z212, conformed to and adapted to seat upon the shoulders A12 when the lid is swung down onto the face of the box and the pivot-truunions are at the lower limit of theirelon'gated sockets A11; but

side to terminate the shoulders Z312 at such point that when the lid is pushed up so that the trunnions areat the upper end of the sockets said shoulders are clear of the shoulders A12, and the lid maybe swung upward freely, the forward oorner'of lthe shoulders i112 following over the rear or upper curve of the boss A", .as shown by the dotted-line position'in Fig. 2; but it will be noticed that before the .swinging movement of the lid can he made the shoulders l 12 must be clear of theshoulders A12 and that the lid having been pushed up slightest exten-t-tends to lock the lid against sliding down again, because. thereby the shoulder i112 is carried over the upper corner of the shoulder A12 onto the upper curve of the lng A', andthe lid is thereby retained .with its pivot at the upper end of the socket throughout the remainder of the opening 'movement i Upon inspection' it will be seen that inthe specific form illustrated, in which the abut- 4'ment' on the lid isoutside of and rides on the abutment 'of the box,vthe lockingI of the, lid againstsliding'exoept when it is resting upon fact that the shoulder A12, formed by cutting away the lu g, as described, is within the circle part ofwhich forms the path described by the corner of the abutment B11I as the lid swings, so that a segment of the circle is cut olf .at

opening to divert the oil which flows down and also'tolcoperate with other features to near its lower or forward edge, has a lip B2,

said blocksl B12 are ont away at the forward to this point the lifting' of the lid to they,the face of thebox-is dependent upon the loo that shouldor,.aud the fact that the shoulder which coincides with the path of sliding of and not a chord. The effectiveness of the` device as a means of preventing the sliding of the lid before it seats on the box-face is greatly increased by this characteristic. The upward-sliding movement of the lid necessary to disengage the shoulders also disengages t-he lips A. and B2 and also tends to increase the tension of the spring C, which is secured to the lid at its lower end and which is caused to slide at its upper end on the corner A1s of the boss in a direction not parallel to the' spring, and the opening movement of the lid is made aga-inst the tension of the spring until such movement has proceeded to the point at which the reaction of the spring on the corner or angle A1s is in a direction radial to the pivot, and from that point on until the spring becomes tangent to the curve of the rear upper side of the boss its tension tends to lift the load, and its friction on the curve of the boss after this point is passed tends to hold it wherever it maybe set. The locking .of the cover is therefore etected both at the hinge end by the engagement of the shoulders A12 and bm and at the lower end by the engagement of the lips Aa and B. I make the elongation of the socket A11 and the lap of the shoulders b12 andAu greater than the engagement ofthe lips A and B', so that when the lid is closing the engagement of the shoulders occurs first and insures the complete closing of the lid down onto the box before any sliding movement cantake place, and thereby'prevents the possibility of a failure to enter the lip Bl within the box and to engage it behind the lip A. 1 It will be noticed that this structure permits the formation of the hood B', so that its upper web at the point B may come down snugly onto the upper side of the boss A' when the lid is closed, thereby excluding all dust at that end, but leaves it free and at some distance from the upper side of the boss throughout the swing-- ngmovement, as will be understood from the dotted-line position in Fig. 2. This is of considerable im port-ance, because when the construct-ion is such that the lid is obliged to swing about'a pivot whose position istmchanged either the tit of the'` lid at any partl corresponding to the hood B' on any part of the box corresponding to th'e bossA' must be I made so free and loose that dust is liable to f enter,-or if it is to be made closethe parts must be machined or dressed into accurate form by the tool, au ordinary casting with its g lnatural rough surface being incapable of being fitted so closely as to exclude dust without danger of increasing the diliiculty of.

swinging the lid to a` degree liable to cause the lid to be brokenin the operation. ItA

should be noticed also that although this lidl has two movements in lopening-first, a slid ing movement, and, second, a swinging movement--the operator is under no necessity to regard this fact, because when he seizes the nose B" of the' lid to open it the natural upward movement will first slide it upward,

disengaging its locked parts at the hinge and lip and then swinging it up; also, in closing the lid no attention need be paid to the peculiar features of construction, the lid being simply swung down regardless of the lo'cking devices, because as soon as the two shoulders Au and b" come into line the actionrof the spring C and gravity tend to cause the cover to slide down, and the initiation of this sliding movement prevents any 'return of the lid which might be caused by rebound from the'box, and the continuously-sliding movement is thereby assured until the shoulder is fully engaged and the lips are locked.

The spring may be secured atits lower end to the lld in any convenient manner, somewhat otherwise when the lid is pressed than when it is cast;' butI do not herein make claim v to eitherof the modes of fastening illustrated,

which will therefore not be described beyond the statement that the spring is rigidly held at that end.

I prefer to make my improved box so that loo if the lid designedjfor it is lost an ordinary lid may be employed, and for that purpose I perforate the lug A' from side to side at the point at which the pivot-trunnions are seated when the lid is free to swing-that is, at the upper end of the elongated sockets. This is the/position at which an ordinary pivot-bolt.

would be required to secure an ordinaryv lid,

and the'extension of the aperture 'through thelug in no manner interferes with the operation of my lid designed .for the box.

When it is desired to make this lid of 'pressed'steel vinstead of casting it, certain detail modifications may be adopted with advantage. The blocks B12 are in such construction most conveniently riveted in plac?l inthe lcorners of the hood. B', as shown inv Fig. 5. The trunnio'us B are preferably replaced by a continuous bolt b", which may exte'nd through the lug A', which is correspondingly modified by having the elongated.

pivot-sockets extended through 4the boss instead o'f being formed merely in its opposite sides, asis sucient when only the trunnions are to be received in such seats.- The trunnions, however, may be employed -in' the IXO pressed-steel construction, lin which case the change described will not be made in the formation of the boss A'; but in order to secure the trunnions rigidly, as. they should be, to the lid, since they cannot be made integral with'it-when it is' formedl of pressed steel, land since they would not he uflicieptly rigid V'unie if merely rooted in the side webs of the hood, l to the box at such elongated bearing andhavu as in the case Aof the 'cast form, I. prefer to form the lid when of pressed steel from va blank, such as illustrated inFig. 6, in which, in addition to the material necessary to form the hood, (which is shown already pressed -finto shape in Fig. 6,) there are lugs B B projecting from the upper edge and adapted I shown as in Figs. 4, 6,'and 7.

to be folded, as seen-in Fig. 7, to form an eye `Vwhich will clasp the trunnion or pivot-bolt,

and to make this eye secure I terminate the lug in a reduced rivet-tongueb, which is in-` serted through an aperture h4, when the lug is folded to form the eye, and is clasped down upon the upper side of the sheet metal, as

lf the trunnion is inserted while the pressed steel is hot, the shrinkage in cooling will cause the eye to grip the' trunnion'secu rely enough to hold it. The same construction may be adopted when a continuous bolt is employed. When adapting the lug B to the use of a continuous bolt, which is preferable with a pressed-steel lid, the pivotsocket,elon gated to permit the movement of the pivot-bolt, is extended entirely through the lug. In vorder to adapt thebox in this form to receive an ordinary lid, I make the slot for `a smaller bolt than is customarily employed as a .pivot for the ordinary lid, and at the upper portion of theslot 'I enlarge it to conform to the usual size of bolt, the excess knecessary to accommodate the larger bolt being out away at the rear side, as seen in Fig. 5. This excess in this positionno more interferes with the action ot' the dev-ice whenmy lid is employed than in boring through the lugto accommodate the v bolt in the form shown in Fig. 1, because the' does the excess of aperture, which consists 1. In combination with the car-axle box havt ing the lng A. at the top, said lug having'trunnion-sockets in itsopposite sides, and slots leading from the rear of the lug to such s'ock- .ets respectively, and having the forwardly- .t projecting angle A1a in vfront of t-he pivdted line of the hinge; the lid having thehood B overhanging the lug, and the spring secured .to the lid'and extending within such hood and bearing upon' said forwardly-'projecting angle of the lug; the hood .having trnnnions projecting inwardly toward each other from its opposite 'sides adapted to seat in the trun nionsockets and to enterfthe same through the slots leading thereto.

said hood being adapted to'come into contact with and stop at the upper side of the lugy above the pivotand rearward of t-he bearing of th spring against such lug when the pivot is at the lower limit of the elongated bearing,

'and to be clear of the upper surface of the lug when the pivot is at the upper limit of the bearings. v
