Patented Aug. 29, 1939 PATENT OFFICE CAR WALL ANCHORAGE FOR CARGO BINDEBS Martin LRowe, Chicago, Ill., assignor to The Gerrard Company, Inc, Chicago, 111., a corporation of Delaware Application April 9, 1936, Serial No. 73,396
.2 Claims. (01, 105-369) This invention has to do' with'the shipment of boxes, barrels and other merchandise containers in railway cars, and'is particularly concerned with the means employed for preventing the objects from moving about in'the car'during transit.
Heretofore it has been the practice, in loading a car, either to block the objects against all movement by the use of wooden braces, or. else bind the objects together into one or more large units which can shift longitudinally of the car under the more severe shocks and impacts. This last mentioned method, commonly known as the floating unit load,v possesses many advantages over To meet this situation and still avoid the highmaterial and labor expenses involved in blocking, some shippers have used metal binders in the form of either wire or flat strap to secure the several lots separately in position, and have nailed the ends of the binders to the walls of the car, but this practice is objected to by the railroads because of the injury caused to the walls of the car by the repeated driving in of the nails and the injury caused to subsequently loaded merchandise by nails and pieces of binder left projecting from the walls.
The object of the present invention is to provide an anchoring means of new and improved construction and arrangement which will allow metal binders to be applied easily and quickly to the walls of a car in tensioned position against the objects stowed in the car and allow the binders to be removed just as easily and quickly,'all without injuring the walls in any way and with out leaving any nails or other protruding members which might injure subsequently stowed merchandise.
The anchoring means consists of a plurality of binder-clamping devices which are located at intervals along the walls of the car, and are preterably set back into recesses in the walls flush with the usual sheathing. These devices will permit the metal binders to be readily inserted and clamped therein and will hold the binders se curely against withdrawal regardless of the degree to which the binders are tensioned against the merchandise.
While the foregoing statements are indicative in a general way of the nature of the invention,
binders I3. Each 01' the binders i3 is in two secother more specific "objects and advantages will be apparent to those skilled in the art upon a run understanding or the construction and arrangement of the anchoring means within the car and the way in which the anchoring means .5 are manipulated to clamp or release the binders.
A preferred embodiment of the invention is presented herein for the purpose of exemplification, together with a slightly modified form thereof, but it will of course be appreciated that the 10 invention is susceptible of embodiment in other structurally modified forms coming equally within the scope of the appended claims.
In the accompanying drawings:
Fig."'1'is a perspective view of the interior of one end of a railway-car, showing the car loaded with objects and the objects secured in position by means of metal binders fastened to the walls of the car by the anchoring means of the invention; 20
Fig. 2 is a horizontal section through the same end of the car, showing the way in which several less than carload lots of merchandise are separately secured in position;
Fig. 3 is a top view of one of the binder fastening devices, showing the way in which the same is attached to the wall;
Fig. 4 is a vertical section through the device, taken on the line 4-4 of Fig. 3, showing the serrated and slotted character of the base plate;
Fig. 5 is a face view of the device;
Fig. 6 is a view, corresponding to Fig. 3, showing the addition of spring indexing means for maintaining the clamping plate in either position into which rocked; and 5 Fig. 7 is a vertical section, taken on the line 1-1 of Fig. 6, showing the way in which the indexing springs are mounted in the. base plate.
As will be observed in Figs. 1 and 2 of the drawings, a number of the binder fastening devices ii are permanently mounted on the side walls I! of the car. The devices are arranged at intervals longitudinally of the car, in opposed pairs, and also in vertical series. The sheathing on the inside of the car is cut away at the locations of the devices in order that the latter will be substantially flush with the side walls and not project to such an extent as to interfere in any way with loading. The objects II to be transported in the car are stowed as shown. If three less than carload lots, A, B and C, are to be transported, for instance, the last lot A to be unloaded is stowed in the end of the car and bound securely in position by means of one or more tions II and ii. To apply the binders ll, the ends of the sections i4 and ii are inserted in the first pair of fastening devices III, which devices will thereupon hold the ends firmly against withdrawal. The other ends of the sections I4 and I5 are then brought together and tied or otherwise secured under tension at it, by means of any suitable binder tensioning and fastening device. After the lot A has been stowed in this manner the lots B and C are similarly stowed, employing the tensioned binders l1 and I8. To remove the lot C at its destination, it is merely necessary to cut the binders It. This will release the objects in the lot C without in any way disturbing the objects in the lots A and B. The lot B can thereafter be removed at its destination without disturbing the lot A.
As will be observed in Figs. 3, 4 and ,5, each of the binder fastening devices Ill includes a base plate i9, two clamping plates 20 and a. U- bolt 2|. The base plate I! is fastened to the side wall ll of the car in a recess 22 formed in the latter, and the clamping plates 20 are positioned opposite the base plate, one above the other, against rounded projections :3 at the top, middle and bottom of the center of the base plate. The U-bolt 2| is mounted in apertures 14 in the studding of the side wall, with the center connecting section 25 of the bolt in grooves 2 in the backs of the clamping plates 20, in which position it provides a pivotal mounting for the clamping plates 20 with respect to the base plate IS. The ends of the base plate I! are serrated at 21 in order to grip the end of the binder I3, and the opposed ends of the clamping plates 20 are rounded and grooved at 28 to properly position and bend the binder without producing any abrupt formation therein which might act to fracture the binder under extremely high ,ten-
The two clamping plates 20 make a double fastener out of the device, enabling one device to grip two binders at the same time, but it will of course be appreciated that in a simplified form of the device but one clamping plate would be used. The clamping plates 20 are preferably provided along their upper and lower edges with flanges 29 and which project into correspondingly shaped cut away portions of the base plate. These flanges do not interfere in any way with the gripping action of the clamping plates 20, but they prevent the gripped ends of the binders from moving either up or down beyond the ends of the serrations ill on the base plate.
The binder, whether it be a. round wire or a flat strap, can be inserted between the plates from either side, and after it has been inserted and bent around the end 01 the clamping plate 29 in the manner shown in Fig. 3, any tension applied to the binder will cause the end of the binder between the plates to be securely gripped and held against withdrawal.
the modification which is shown in Figs. 6 and 7 a Single clamping plate 32 is employed and the plate is held by the yielding resistance of a spring 33 in either gripping position into which rocked. The Pressure of the spring 33 is "sufficient to .hold the end of the binder frictionally between the clamping plate 32 and the base plate 14 if any slack should develop in the binder. 'Ijhe spring 33 is provided with a projecting nose portion '35 which bears against either one .side or the other of a projection 36 on the clamping plate, with a biasing action.
- I claim:
' 1. In-a freight compartment having an end wall and two opposed side walls, objects loaded in the compartment against the end wall, binderfastening devices permanently mounted on the side walls opposite each other, and a binder secured at its ends in said devices and tensioned across the compartment with its intermediate portion positioned under pressure against the objects loaded in the compartment.
v 2. In a freight compartment having an end wall and two opposed side walls, objects loaded in the compartment against the end wall, pairs hinder-fastening devices permanently mounted on the side walls with the devices in each pair opposite each other, and binders secured at their ends in said devices and tensioned across the compartment with their intermediate portions positioned against the objects loaded in the compartment, said devices clamping the ends of the binders with pressure which increases with an increase in the tension of the binders.
