(ci. 10s- 369) The present invention relates to anv end load ace which has been adapted for usein freight cars of the box car type, andthe subject mattei' thereof has been divided from my prior application for patent on an improvement in a Load brace,l Serial No. 441,251', filed May 1, 1942, now

Patent No. 2,336,869, dated December 14, 1943.

In the'past it hasv been common practice to utilize the very conveniently located .door posts of a' box car forv nailing the variousparts or' the partitions thereto particularly when the car is being loaded at one end only or at both ends individually with different merchandise.

'i IAn object of the present invention is to provide the box car with load braces which can be readily adapted for building up partitions transverselyof the freight Car.

Another object is to provide cooperative means disposed in substantial alignment with the door poststransversely of thecar to provide a means for holding a timber intermediate the'sides of the l car to back upthe load when one end of the car lis, being loaded, this timber being readily removable and replaceable without'resorting to the use of nails. Heretofore, the-use of upright timbers kin the center portion o f the ca'r, by fastening the -same with nails or the like, has also been objectionable by reason of the fact that the car floor Vand the ceiling structure eventually had to 'be repaired due to the mutilation accompanying this method of building up of crating partitions.

All other v objects and advantages associated with thedeviceof thisinvention shall hereinafter -.,liig. 3 Vis an enlargedvertical sectional view taken along the line 3-,3 in Fig. 2.y

Fig. 4 is a horizontalsectional view taken '.along the line 4-4 in Fig. 3, and

Fig. 5 is a plan view of the Well or bottom unit per se which is adapted for holding `the lower en pf the centraltimber in the car.

,Referring now to Figs. land 2 which diagram-l matically illustrate the general construction ofk a freightcar of the boxcar type, the ycar generally consists ofathe 'side walls IU and Il, end walls l2 through a ance of the carbeing closed by the ceiling structure I6 and flooring l1. Adjacent'the openings for the 'doors I4 and vl5 are'the door posts I8 an'd I9 at one'side of the car and 2B and 2l at the other side 'ofthe carrespectively. Some of the `freight cars are lined from floor to ceiling with an inner liner that is usually builtflu'sh with the door posts, but in the 'car illust'fra'tedy a belt lining determining the storage or shipping spaces A and B. The partition backing up the load at A in the box car is designated as a Whole at 23 while the partition backing up the load at B in the box car is similarly designated as 24. The foregoing partitons are used when backing loads less than the Whole car loads `and when a full carshipment is being loaded the partitions 23 and 24 will not be used, but longitudinal partitions such as `indi-` cated in

dotted lines

25 and 26 are then employed.

In order to carry out one` of the objects of this invention, a plurality of clamping devices as indicated at 21 in Fig. `2 have been provided and Aassociated with the door posts.` Also, centrally of the car, suitableceiling xtures and floor wells have been utilized and are indicated in general at 28 and 29 respectively.v

The clamping devices 2l abovereferred vtoforxn no part of the present application but are fully described in the above identied parent from which thev present lapplication has been divided.

" Reference may be had tothe aforesaid parent for a full understanding of said clamping devices. The latter are employed to removably secure timbers T to the door posts as seen in Figs. 1 and 2. It is apparent from the foregoing explanation that-timbersvsuch as T can be" used and replaced at will to form a protective lining for the door posts and thatth'ey may beused for the reception of nails should that becomev necessary, or else they may be used as vertically disposed shoulders to hold the partition individual pieces or planks P of the partition 23 as bestillustrated in Fig. 2. The common practice is to beginloading a car at the extreme end thereof progressively stackingr the merchandise toward the fcenter of the car and then inserting the partition pieces or planks y P one by one as the heightofI the loadlncreases.

f Under normal conditions the load, when relatively heavy, will only be stacked or piled high enough 'and;|3, and thelusual doors I4 and l5,-the bal- 55 to be approximately level withthe belt lining and Well iixtureA 29 is suitably nested in the car ooi" l1 and secured by a plurality of screws 46. This s well is provided with a cover 41 which isnormally closed by means of a spring-actuated latch bar 4S having its operating member flush with the car iioor surfaces `and the surface of the cover M. Cover 41 is hinged by means 'of pins 48 oppositely disposed, the pins being locked against loosening by a spacer 49 suitably secured by means of screws 56 to the underside of the cover 41. 1

VThe well. iixtureiil has its opening 5l of such ,proportions as to loosely receive a'timber T' therei'fn andone face of the openingi is provided with ,aretaining lip or claw `52 which` is adapted to bite into'the timber T" upon the insertion of a Wedge lW in. the manner best shown in Fig. 3. By the use of the wedge, thetimber T is readily secured *tol the car floor without nailing of' the timber to the floor and the wedge Waiter it has been driven in. place can be suitably nailed to the timber T as at 53-to prevehta'ccidental retraction thereof. The upper end of the timber T' is adapted' to .bereceived in a header 55 of the ceiling xt'ure 28,' the header having a laterally disposed side Vthereof open as at 56 to allow the timber T to enter into the pocket portion of the' header. The header 55 yis suitably secured to the ceiling structure by means of" screws 51 or any other suitable means while a bracket 158 is connected between the header 55 and the ceiling I6 at the sideof the header oppo'sit'ely disposed to the pressure of the load.

Within the pocket portion'of the header 55, the

device' includes a cap' member B0 'which is norm'ally urged toward' the car'floor and against the upper end of 'inserted'timber'T by suitably acting and supported springs '6L For all practical purposes the spring'sl can' be of sufficient strength 'to' hold' the' timber T against movement out of the header', 'but thisaction of movement-of the timber toward the opening 56 is readily oounteracted' 'andA prevented by the wedge W actingwithin the well opening 5l.

"In ord'erto properly guide the upper end 0f the timber T underneath' the cap 60 of the header I'55, a suitable strap'62, which may or may not be in `the form of aspring leaf, is riveted to the cap as at 63' and has a looseupturned end encircling a rod B4', the" end portions* of the rod 6l!V being vertically guidedby the bearing blocks B5 for' limited vertical movement which has been lprofvidedl to compensate for the vertical movement of the cap 6D upon insertion and removal of timber 'TC' To further-facilitate the placing of the timber T intov position to be clamped by the cap v'member B0, the upper corner y66 of the timber T' is chamfered.- the AlowerV corner 61 ofthe same timber; likewise being chamfered to facilitate insertion into the-wellxtureZS.

, It isi tol be understood' that in building up a partition the planks P thereof are nailed to the oppositely disposed rtimbers T at the door posts to fasten them in place and they may be also nailed .to the timber I" which is intermediate the timbers Obviously, the foregoing description relates to a preferred embodiment of the device as shown and illustrated by Way of example in the accompanying drawings. It is contemplated, however, to make such changes as may be governed by the breadth and scope of the appended claims.
