Swann, Homewood, 111., assignor to Standard Railway Equipment Manufacturing Company, Chicago, 111., a corporation of Delaware Application October 29, 1949, Serial No. 124,345
This invention relates to improvements in means to secure the ends of high tension lading bands which are used to tie down lading in open top cars when such lading extends above the sides of said cars.
In common practice it is not unusual fortrainmen to burn or drill holes in the side sheets or top chord of such cars through which said bands may be inserted and looped for connection with the main portion of said bands. When such parts of a car are thus punctured a weakening of the structure and more rapid deterioration results.
It is the principal object of the invention,
therefore, to provide an effective securing means for the ends of said bands, which means may be readily attached to new cars being built, or to old cars already in service. It is another object of the invention to provide such a band securing means which is nonremovable but slidable along the top chord of said cars so that the same way may be selectively positioned along said chord to best advantage in securing the lading in the car.
A further object is to provide such a band securing means with means to secure either the ends of lading bands or the ends of boltsin instances where a more substantial lading securing means may be necessary.
A still further object of the invention is to provide said securing means in two pivotally united parts so that said means may be applied to the top chord of a gondola car without alteration in any respect and so that when applied and the parts fixedly united together, the securing means will then be non-removable and slidably attached to said chord.
It is'another'object'of the invention toassociate with either the one piece or two-piece modification of securing means a cam whereby when upward pull is exerted on the securing means the cam will bind against a surface of' the chord and effectively resist sliding of said means on said chord. 7
Other objects and advantages of the invention will appear in the following description thereof. Y 7
Referring now' to the accompanying drawing forming part of this application and wherein like reference characters indicate like parts: Fig. 1 is aside view of a one piece banding clevis illustrating means. for securing either a band or bolt thereto, and showing associated car parts in section.

In the drawings, l indicates the upper margin of the side sheets of an open top railway car and 2 the top chord thereof which, in this instance, is a bulb angle, as is common in such cars. Such angles have a depending flange 3 and a horizontal web portion 4, extending outwardly from upper edge of flange 3, and terminates in a downwardly extending bulb portion 5. Flange 3 is rigidly secured, as by welding, riveting or otherwise, to said upper margin I of the side sheets.
The securing means shown in Figs. 1, 2 and 3 is designedso as to be slidable along said top chord 2 but be normally non-removable therefrom, and comprises a channel-shaped structure including a base portion 6 of a length approximately the width of the web portion 4, so as to having a downturned flange 1 partially overlapping flange 3 and a downturned flange 8 approximately equaling the depth of and overlapping the bulb 5; said flange B'having a'reflange 9 inwardly turned so'as to underlap the bulb 5. The sides of said securing means are provided with integral upstandingreinforcing webs-or walls l0 which are of increased height approximately above flange 8,-and between the outer upper portions of said walls ll! extends a round bar or rod. H which is adapted to be encircled by a load retaining band 12, 7 It is apparent that a band securing means such as thus far described would be sufiicient' as an anchor for high tension lading bands only, and also that once said means is' applied to a bulb angle, as shown in Fig. 1, it cannot be removed normally. To apply the same-to a bulb angle it could be slide thereon longitudinally from one applying the device to equipment in use, the bulb angle would'jrhave to be cut-out sufficiently,
' as shownlat |3,.in' Fig.3, when asmany of'the devices as desired may be applied, after which a filler piece could be welded in the cut-out portion, or a stop, such as shown at l4, welded on the web 2 of bulb angle adjacent either end of the cut-out portion so as to prevent the securing means sliding torthecut-rout portion 13 and accidentally being removed therefrom.
In those instances wherein it is desirable to provide an anchor for either of two different types of banding means for optional uses as desired, I have shown an embossment l5 integrally formed with and projecting outwardly fromthe base portion of flange 8, said embossment being ,semicylindrical in form and having a holezl fizth-rough same and the base of flange portion 3, the axis of said hole It being parallel with said flange8 and spaced outwardly of the bar or rod l I Thus when the device is used to anchor heavy lading, such as machinery or the like, a long bolt I! may be passed upwardly through:.said hole I6 to a beam or other suitable membervextending transversely of the car over said-lading andto which the ladingiis secured. Thus an anchor:is.proyidedadaptable for anchoring either of two-rdifferent types of ladingsecuringl means for optional use, dependingupon the character of the lading being transported.
Figs. 4 and 5 illustrate a modificationof-the invention whereinlmcansiis provided to clamp the band holding device against vlongitudinal movement along the rail. 'In these figures corresponding partswh-ichare identical with the like parts-imFiguresl, 2 andlS bear the same reference characters;-for example, the sidewall sheets :are indicated at l,-.the bulb angle 121comprising the flangefipwebl and-bulb-5,;and the banding clevis comprising .th'e'web-or base portion 6, the dcwnturned'inner flange outer :flange J8 and reflange fl. In this modification, howevenwalls Iii-are provided withapair of outwardly projecting-axially alined studs :20. -A-channel-shaped yoke comprising spaced arms Zland-a connecting rod .or pin1-22- extending between correspondingiouterends of arms '2 l,-is provided, said arms straddling said'walls Ill-and-having-ax-iallyalined 1.

The lower-edges of said arms 2! arearcuate between-their ends, and at their inner ends are formed with a cam-likesurface 24. It will be noted that when the parts are assembled, asshownin Fig.'4,'onza-car-bulb angle, the distance between the rod 22 land the topiof'the bulb-angle issuch-inrelation to the width of the arms -2-!, that ,the arms cannot be removed from-under studs 20. With'this:struc- -ture,'-when a lading -fband or'strap lisiappl-ied around-rod 22, as: indicated in dotted lines at 25, and 'an: upward tension applied. thereto, camsurface'ZA will bindagainstlupperasurface of the "bulb angle web -.4 and positively preventsliding of the devicealong said-bulb angle;
' Figs-6 and '7 illustrate a two-piece modifica tion of the invention which :m-ay be, applied to the bulb angle without alteration of \same, and when applied is normally non-removable therefrom. Inthese views also,-the sidesheathingis indicated at I, and ,thebulb angle comprises the web 4, fiange--3=and bulbl5, secured to saidlside sheathing. Theouter part of. the two-piece clevis comprisesla main portion having spaced parallel wallslafl which partially overlap web '4, (extend downwardly adjacent bulb 5,and underlap the bottom edge of saidbulb' 5,..asfat 3|. An integral web32 extends betweensaid walls'30atthe inner aline'd holes 35, and the arms 33 are likewise provided with axially alined holes 36, which holes 36 are selectively registerable with said holes so that when the parts of the clevis are in op- "erable position on top rail l2, as shown in Fig. 6, along pintle-31 may be passed through the registering fholes 35-35 and 3B36 and be held 'therein'loy means 30f the cotter key 38.
This pintle 3'! forms the means about which one end of a-bandingstrap may encircle and be anchored thereto.
.For those instances where it is necessary for a bolt to be used in securing heavy lading, I have shownanangle-piece .39 .secured at its ends by welding or otherwise to the sides 33 and spanning the space :therebetween, and which also Lkeeps saidsides in propeixspaced:relation. One arm 40 of said angle piece is disposed substantially parallel to -the base of :saidnarms 33.-andis provided with a hole 4 i vtherethrough, through-which may extend-a; bolt 12 with-the-head thereof .retainedunder. said. arm 40. When-boltsareused, they are insertedthrough saidholes when-arms 3 are in elevated position;= as shown in l dotted lines, Fig.- 6, and when l the-parts areiin-the, DQSi-r tion shown in full lines, Fig. 6, the bolt cannot be removed-nor can the clevisbe removed from the bulb angle, but it maybemoved longitudinally therealong. V
It will .be noted in Fig. 6-that thedistancebetween flange 3| and base of arms 30*is..slight1y more than the width of the bulb vi tor ease of application thereto, and also :it -will .be noted that the .lower outer corners of arms 43 are chamferedias at-43, which portions 43 rest upon web '4 when arms :33 are raised .for application of the clevis-to-the top rail. When howevensaid arms 33 are lowered so that: the-base of said arms rest upon web l, the arms 30 will-thereby be raised so thatthe flange -3 I firmly: engages "the "bottom of bulb 5.
In the modification shownin Figs-842 -.the lading bandanchor comprises a-lbase ;portion having a downturned iflangetl partially-overlapping flanges and a downturnedflange 52 and a refiange .53 which aterminates in an upturned adapted to be encircled-bye high tension lading j band. .By providing a triangularly shaped bar -56 .lthe lading bands .ma-y be appliedsolas to extend in any or all of three-differentdirections, a -material advantage over the other smodifica tions,- Extending upwardly Lfrom opposite sides of flange 52 is a pair of wall 5! which support the. oppositecorners .of thebase ofsaidtriangular bar 56. The triangularly shaped bar56 is .thus supported in spaced relation to'baseportion ill. Between walls 5Tv is formed a hole '58 through which may extend abolt similar to bolt I11 for supporting a beam extending acrossiithe topof lading -and therebytying said lading ingplac'e. This modification of the invention is -appl-iedto the top chord of a c'arf'in 'the'samema nner asin the other modifications and is adapted to slide longitudinally along the bulb angle. The flange 5| is provided with a recess 59 for reception of the key 60, the lower end of which is bifurcated, as at El, and the body portion of which is provided with an elongated slot 62. A lug 63 extends inwardly from flange 5| into slot 62 and holds the key in place in said recess except for sliding movement from one end of the slot to the other over lug 63. The bifurcated portions BI is adapted to slide down over and rest upon a rivet head 64 and when in such position obviously the clevis is locked from sliding longitudinally along the top chord. When, however, the key is raised as by the laterally extending lip 65 the key is freed from such rivet head and the device may be slid longitudinally to any position desired on said top chord. The rivet head 64 illustrated is one of a row of spaced rivets which unite flange 3 to upper margin of side wall I of an open top railway car, such a a gondola car.
