IIARBERT, orr CHICAGO, ILLINOIS, AssIGNOR TO ILLINOIS RAILWAY EQUIP; LIEN-Ir COMPANY, orv CHICAGO, ILLINOIS, A CORPORATION or ILLINOIS LOCKING MEAN S i Application iled July 13,

4My invention relates. to means especially intended for fastening or locking the hatch covers of railroad refrigerator cars, either in closed position or-in a predetermined ventilatingy position.

A The' invention .has for its Object the provision' ofmeans sosecured orassOci-ated with a swingingmember Or'lever arranged adjacent'to the hatch that said means maybe n readily moved. alongl the lever and be positioned for locking the hatch cover in closed position or. lockthe cover in a predetermined raisedlpositidn for ventilation; the relation b etweenpthe lever. and locking means being m such that dissociation 01E ,the elements is impossible; whilei at the same time. said means are'so constructedand arranged that engagement with, the running boards or with portions of the carroof is impossible. 2Q The ,objects and advantages of my invention will be readily comprehended from the following detailed description of the accompanying drawing', wherein:

'Figure' 1 is a plan view of a portion of car- Zi roof witha hatch cover in closed position,

illustrating my improved means in cover locking position.

Figure 2 is a transverse sectional view with the lockingmeans in side elevation; a ventii! lating position of the cover being shown in dotted lines.

Figure 3 is a perspective view of the locl ing means un'attached.

Locking means as heretofore employed con- 35. sisted of a hook secured to the hatch cover by means of a chain and the hook intended to pass through a suitable staple on the car-roof which cooperated with a lla-sp member secured tothe hatch cover. This type of fastening means has been found to be very Objectionable` becausel the hooks were free to become engaged: with the running boards on the car-roof when in unlocked condition because the chains permitted` the hooks to shift or be moved along the roof and. also. to swing 1931.

into the hatch Opening when the cover is being moved to closed position.y ,As a result, considerable damage and' loss of the-hooks has been encountered When'the heavy hatch Covers were swung1 and dropped into Iclo'seil position@ v. i'

My improved .means :is designed ,to overl come these serious' objections and to provide means which may be readily secured'toequifp'; ment 1n use. Q I y The specific embodiment. of my vinvention as-disclosed in the drawing involves ya member or shoe 10 which is. adapted toibe slidingly mounted on a link or barll Whose one end is pivotally secured at ,12, to an upstanding bracket. member 13. The bracket meniber 13, for purposes of exempliicat'iom'lis shown in the nature of an Lg-shape bar, one leg or side whereof is intendedtojbe. secured to the car-roof as by means ofthe bolts '14, 14, see Figure 1; while the other leg or side extends vertically upward. vThis bracket 13 is secured to the car-roof adjacent to the hatch 1.5 so as to be slightly spaced from thelfree end of the hatch cover 16, whose opposite end is7hingedly secured in place, as shownjat 17, 1

The link or bar 11 is pivoted to the bracket 13 so as to swing over and into substantially parallel relation with the cover 16 when the latter is in closed position, as shown in full linesI in Figures 1 and 2; and this link or bar is preferably provided with a number offopenings or slots 18, spaced apart lengthwise of the link 11.

'1 ie member or shoe 10- is shown provided with two

side wall portions

19, 19, which extend above and below the intermediate body portion or web 20, which is of length sub Stantially equal to the width of the link or bar 11 so as to permit the latter to extend between the depending portions of the

sides

19, 19. The lower ends of the

sides

19, 19 are shown provided with the inwardly disposed

flanges

21, 21.

These opposingly arranged

flanges

21, 21 are spaced from each other a distance less than the width of the link or bar 1l; and are spaced from the body portion or web 2O just sufficient to accommodate the thickness of the link or bar 11 so as to permit the member or shoe 10 to freely slide lengthwise of the link or bar, but Without undue play therebetween.

The portions of the

sides

19, 19, disposed abovethe body portion or web 20, are provided with aligned openings or :holes at 22, generally corresponding in configuration with the cross-sectional configuration of tho locking member or; pin 23, so as-to permit lengthwisesliding movement of the pin 23.4

The pin 23 is in the nature of a Ushape hook with one leg or side 24 of greater' length than the other side; and this side 24, at its end, is provided with a laterally disposed lug oiuenlargement as at 25. 2

1=Qnei sidel of each opening 22, in the upstandin'g `side portions `ofshoe 10 is proj Ivided with a laterally disposed enlargement or s l 0t '26,- intended to correspond in shape with the shape of the enlargement or lug4'25 on .the end of the pin 23. f,- The slot portions 26 and the lug 25 are arranged to be out .of register with each other when the pin 23 is in normal assembled lrelation with the shoe or pin holderflO; and there'- fore, 4in the' drawing, the lug 25 and the

slots

26, 26 are shown ninety degreesapart relative to the axis of the long leg or side 240i the locking pin 23; with the distance between the lug 25 and the adjacentside 19 of the shoe 1 0 less than the length of the short leg or side 27 ofthe-locking pin23. As a result of this arrangement,the4A long leg 24 `of pin 23 must first be inserted through the openings 22 in the sides 19 of the shoe 10 by turning or holding the short leg 27 vdownwardly so as to bring the lug into register with the Aslots 26; the short leg or side 27 is then swung upwardly into the position shown in Figure v3 and the free end ot the link or bar 11 is then passed transversely through the shoe 10 intermediate of the bod),v portion 20 and the intnrned lianges or bottom e2;-

tensions

21, 21, with the short leg or side 27 of the pin 23 resting on top of the link or bar 11.

llVith the short leg or side 27 resting on top of the link or bar 11 as described, the lug 25 on the long leg or side 24 of the pin will be disposed as shown in Figure 3 and therefore out of register with the slots 26, 2G. As the distance between the lug 25 and the adjacent side 19 of the shoe 10 is less than the length of the short leg or side 27 ot the pin 23, it is apparent that the end of the short leg 27 will at all times rest on top of the link or bar 11, thus making it impossible to bring the lug 25 into register with the

slots

26, 26 and hence dissociation of the locking means will be prevented. i

After the locking means has been assembled as described with the shoe slid onto the link or bar 11, the free end of the latter is then provided with a rivet as at 28 which prevents the shoe 10 sliding oli the free end of the bar 11.

The hatch cover 16 at a proper distance from its free end is provided with a suitable staple 29 which is intended to pass through one `of the slots 18 in thebar 11 r`when the eoy'ii isj:iniclosedfpositionfas; 'showin in Figu'r`e`s4 '1 and 2;"a1id this lstaplex 29 intended to receive the short leg 27 of the pin 23,

thereby holding thelink- .onbar 11 'in sub- `stantiallyparallel relation-With the hatch cover 16, as shown, and latching the cover i-np'laee.

The short leg 2 7 and the long leg 24 are t provided with registering openings or

slots

30, 30 Whichare adapted to receive the usual car/sealing elementin the nature of a wire or metal strip, indie'ated'atBl infFigure 1; the wire 'onstrip being}p; 1ssed through both slots and the ends sealed togeth'enwith'solder oiother suitable sealing me'dinni', l'asfinjdises ,at 31e' in; Figure. 1.5 Mo'vemnt @fthe short sideor leg v27 out of thestiple 29, with-v outiirst breaking and'reinoviiigthe seal, is thus prevented. In order 4to preventftoo farI transverse n iovementv ot the Vpin 2 3 'that'. theslot 30v of leg 2 4 would be disposed within theopening 22 of the yside wall of shoe 1 0, Lpiefer to DrOvide' the leg 24fat the ,inner or hfok'end Vith a lug 32, see Figure eitendin'gfin 7the same direction as lug 2`5 so that lug 32 will bahut, of register with `the slot. portion 26 of the opening y22 1in 'the'. side wall ,f19 ofthe shoe 10 and thus provide a'stop for limiting the inward movement y ofi-'the pin -.tovvard locking position, as' shown Vin Figure 3.

In order to permit the hatch cover`16 to he held in ear Ventilating position,1I show the cover 16 provided with a hasp or strap 33 whose end extends beyond the free end of the hatch cover as shown in Figure 2, and the strap provided with asuitable aperture 34 extending horizontally therethrough.

The strap 33 may be an integral part of the staple portion 29; and this strap is suitably secured' to the cover 16.

The extended end of the strap 33 is intended to fit into any one of the slots 18Ain the linkA or bar 11, as shown in dotted lines in Figure 2; and'this adjusted position of the elements is maintained by sliding the shoe 10 along the link or bar so as to position it adjacent to the strap 33 and'then passing the short leg'27 of the hook-pin 23 through hole 34 of strap 33. When necessary, the means may be sealed in this position byemploying the usual sealing means as heretofore described.'

Providing the link or bar 11 with a numpurposes of description and not as terms of y limitation, as modiiications may be made without, however, departing from the spirit of my invention.
