(Cl. ZBO-145) 6 Claims.

This invention relates to vehicle body construction and particularly to a bolster and bolster post, sometimes called a vehicle stake, for use in retaining loads of materials, such as logs, lumber, beams and the like, upon the vehicle. The general object of the invention is to provide such a bolster and bolster post combination in which the bolster postrmay be released and allowed to pivot outwardly and downwardly to a position below the horizontal so as to release and allow easy removal of the load from the vehicle without endangering the operator.

It is a further object of this invention to provide such a bolster post which may be readily applied to the usual bolster of a vehicle.

Another object of this invention is to provide such a bolster post and support therefor which will have suficient strength to support and retain heavy loads, yet in which the support is of small dimensions and does not necessitate the use of special bolster construction.

Another object of this invention is to provide a means for positively locking a bolster post in its operative position.

Another object of this invention is to provide a bolster post oi the character described in which the stresses exerted on the posts by the load will be transmitted more directly from the bolster post to the bolster, and in which the transmission of such stresses will not be dependent upon the strength of the means for securing the post mounting to the bolster.

Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawing in which is set forth by way of illustration one embodiment of the invention.

In the drawing:

Fig. l is a side elevation of a bolster and bolster post carried thereby, with a portion of the bolster cut away and shown in longitudinal cross section for the purpose of illustrating the construction of the mounting for the bolster post;

Fig. 2 is a bottom plan view of the structure shown in Fig, 1;

Fig. 3 is an end elevation of the structure shown in Fig. 1;

Fig. 4 is a perspective View of the block by which the bolster post is mounted on the bolster;

Fig. 5 is a perspective View of the lower end of the bolster post showing the portion which receives the latching bolt for latching the bolster be employed for securing the bolster post extension in the clevis on the main bolster post.

The usual bolster employed in connection with trucks, trailers and similar vehicles for hauling logs, beams and the like is that of an H-beam having side flanges I and 2 and a web 3. 'This extends across the vehicle and the load is adapted to rest upon the upper edges of these H-beams or upon a flooring placed thereon as the case may require.

' In accordance with this invention, a main Vehi cle stake orl bolster post is mounted on each of the respective ends of the bolster as follows:

First, the web 3 of the H-beam forming the bolster is cut out for a short distance from each end. There is then placed between the sides I and 2 of the H-beam a block as shown in Fig. 4, said block having a pair of spaced bearing flanges `or ears 4 and 5 parallel to bu t separated from treme outer surface of one bearing ange to the n extreme outer surface of the other bearing flange. This tongue-like part 6 is adapted to fit under the end portion of the web beyond the part which is cut away, this being clearly illustrated in Fig. 1. The block is then preferably Welded or otherwise rigidly secured to both the Iianges and the web of the H-beam in the position shown in Fig. 1.

The bearing anges 4 and 5, as above stated, are spaced apart and the lower end of the main vehicle stake or bolster post 'I is of a thickness to t between these flanges. The flanges and the portion 'I of the bolster post are formed with holes 8, 9 and Ill respectively through which will be passed a pivot pin or bolt II, thus pivotally mounting the bolster post on the bolster.

The bolster post may, if desired, be provided adjacent its upper end with a clevis I2 having an opening therethrough for slidingly receiving the bolster post extension I3, This bolster post extension has openings I4 at spaced positions along its length for the purpose of receiving the removable pin' or bolt I5 by which it is secured within the clevis I2. It will be noted that the pin I5 is provided with extension I6 which is pivoted atv I'I to the body of the pin, so that when the pin is inserted and the part I6 is pivoted to a position at right angles to the main body of the pin, the pin cannot be withdrawn until the part I6 is Y Ving bolt lea extends-through an opening I1 provided for the purpose in the tongue-*like part 6 of the mounting block, and when the bolster post is in its upright position the bolt I 6a, may be moved toward the bolster post into the notch l a to hold the bolster post in its upright position. It will further be appreciated that a force tending to move the bolster post down to a horizontal position will exert only a shearingforce on the bolt Ita, and the stress. will be transmittedfdirectly through this shearing action on the bolt andthrough .the tongue-like part 6 on the block to the web 3 ofthe Hbeam.l The transmission of 'this vforce will -depend to a `very small extent vonly upon the strength of the welding or other meansof Vsecuring'the mounting blockin .position on the, i H -beam.

The bolt Ea'is adapted to' be actuated by means of'a lever'l8 `which extends through the slots IS in the flanges ofthe H-beam vbeneath the web 3 and is pivotally mounted at on a bracket 2i carriedfby one` of the side-ilanges; This lever is connected to the boli-l |6a; byfmeans of links 22 'so that `when the lever f8 is swung about its pivot in one direction `or the other the bolt will be Amoved longitudinally into or out of engagement with the slotV 15a, in the 'Vehicle post.

In order that the llever ,i3 might be moved to release the `vehicle post without .danger to the operator, there is pivoted tothe Vfree end of this lever at 231arod 24, and the opposite end of this rod'is pivotedat 25 to a lever 26 adjacent the remote end of fthe bolster, said lever being fulcrumed .at 21 to a bracket 28 on the bolster. The lever '2B v has a handle -29 which may be grasped to move'the'lever .12W-and the linkage just described-for the purpose oi retracting the bolt I6 and .lreleasing thebolster post. The bolt 15 `is normally/held in its'engaged position by means of a Vspring --30`extending betweenr a part of the rod'24 anda suitable meansfor attaching it to vthe bolster. v

Fromthe foregoing itWill be seen that a means has fbeenprovided 'for carrying out all of the objects of this invention, and that by the means provided a suitable bolster post may be secured to a 'customary type :of `vehicle bolster without the 'necessity for any special construction of the bolster or any additional bolster. It will further be seen lthat a :meansxfor mounting the bolster Vpost on'the bolsterhas been provided in which the stresses upon the lbolster post will be transmitted directly to the bolster with the least possible stress transmitted 'through the Welding or other parts v'securing the mounting to the bolster. Y

In addition to the'foregoing, it will be appreciated that the construction `illustrated may be secured in place-without'the necessityLfor a great dealof skill or any :unusual orfspecial tools, and

that'when secured lin Vplace it provides Aa means whereby'the bolsterzpostrm'ay be rigidly heldin working position and yet may be released by an operator standing on the'opposite side ofthe .vehicle where he `willbe relatively :safe from any injury.-
