Application filed March 7, 1913. Serial No. 752,687.

To all whom it may concern: 1

Be it known that I, ELBERTG. CHANDLER, a citizen of the UnitedStates, residing in the city of Portland, county of Multnomah, and State 0f.Oregon, have invented cert-ai in L0 Bunks, of which the to lowing is a specifica-,- tion.

M'y invention relates to log bunks, and more particularly to a bunk such as is mounted upon a fiat car, truck, or other vehicle, to receive and hold logs or other objects whic-hare capable. of rolling of being otherwise accidentally misplaced during the transportation thereof. Among the salient objects of my inven-- tion are,'to provide an improved bunk of the character referred to having holding chocks adapted to move down into the body of the blink and below the uppermost supporting surface thereof, when released, whereby, to permit the object held to be 'unloaded; to provide in a bunk of the char acter 'referred .to, improved mechanism whereby the-holding chocks can be released from the opposite side thereof, whereby to avoid the danger incident to releasing or tripping said chocks at the side of'the car from which the load is to be discharged; to provide in a, bunk of the character reing the holding chocks to different holding positions, whereby they can be readily and quickly adjusted without the necessity of releasing hooks, bolts, or other fastemngs; to provide in a bunk of the character .referred to improvedmechanism for holding the chocks in operative positions and for permit them to move down intothe body of the bunk and thereby release the log or other'object; and, in general, to providean improved, simplified and practical bunk of manufactured and 'put upon the market at a minimum expense.

In order that others may understand my invention, I have shown in the accompanying sheet of drawings,one practical embodiment thereof, which I will now describe.

Figure 1 shows aside elevation of a bunk embodying my invention, with a part broken out -to reduce the size of the figure, and with a part in longitudinal section to show the inner construction and arrangement,

with a portion the top removed, and as if taken on line 2-2 of Fig. 1,; Fig. 3

is a cross sectional view 'taken on line 3-3 -of Fig. 1'; and Fig. 4 is a view on the same line with the tripping mechanism released and the holding chock down in the body of the bunk.

Referring to the drawings, the body of the bunk is preferably square or rectangu'lar in cross section and is of -such length as is best adapted for the carv or other: vehicle upon which it is to be used. The body can be made in a variety'of ways, but as here shown, it is made of two heavy sheet metal side pieces I and 2, withza channel'iron top 3, and a bottom late 4 having upturned edges between w ich the. side pieces 1 and 2 are placed and to which they are riveted. The top plate 2, ateach end, is provided with a suitable slot or longitudinally extending opening, as 5, for a purpose hereinafter again referred to.

Secured to the inside of the side pieces 1 and 2, at each end of the bunk and opposite each other, are bracket members 6-6, having corrugated or notched upper edges, one member of each pair being provided with two pairs of hinge lugs, as 7-7, and the other member of each pair being vided with a flange-like portion, as.8,'. or a purpose hereinafter refereed to.

A chock 9, having trunnro'ns l0, substan- I tially of the form shown in side elevation,

Fig. 1, and top plan view, Fig.2, is movably and changeab-ly mounted-through the I opening or slot 5, in the ,notches of the;

bracket members M6, the upper end of said chock 9 being adapted'to project above the top or'supporting surface of the bunk for holdingthe logs or other objects. placed thereupon, and the'lower end thereof being provided with a lip or flange portion, as-ll,

for a purpose now to be described, it being understood, of course, that there is a choc at each end of the bunk.

Hingedly mounted between the hinge lugs 77, upon one of each pair of brackets 66, is a swinging plate or member-'12, the lower edge of which is slightly beveled, as indicated in Figs. 3 and 4, this swinging member being adapted to be moved out wardly, as indicated in Fig. 3, to engage the.

lip or flange 11, upon the outer end of the chock'9 which lip or flange, it will be noted,

"is also beveled, and adapted to have a flat engagement with the edge of the swinging member 12.

It is to be noted also that the angle of engagement between the end of the swinging member 12 and the lip or flange 11 of the chock is such, relative to the hori- Zontal component of the pressure between the two surfaces, as to overcome the fric tion therebetween, so that when the swinging member 12 is released by the movement of the operating rod hereafter referred to, the strain on the chock 9 which Causes its lower end to rise, forces the swinging member laterally to the position shown in Fig. 4 and thereby allows the check to rock on its pivot bearing. The lip or flange portion 8 on the oppositebracket, serves as a bearing against which the opposite side of the chock 9 bears and by means of which said check is prevented from being moved laterally.

the swinging member 12, at opposite ends of the bunk, are moved outwardly by means of operating rods mounted longitudinally of the bunk and in the lower corners thereof, as indicated by the numerals 13l3, said rods being held in suitable bearing blocks l4 14, each of said bearing rods being provided adjacent the swinging member 1212, with offset portions, as at 15, adapted to move outwardly against said swinging member 12, when said rods are turned, as indi cated in Fig. 3. Each of said rods is provided at its operating end, with a long, upturned portion, as 16, which servesas a lever or handle, and at its opposite end with a shorter bent portion 17, bycmeans of which said rod can be turned, when there is no load, for the purpose of adjusting the chock at that end; that is, it is possible for one man to turn the rod with one hand and hold the chock with theother.

The chocks 99, at the opposite ends of.

the bunk,- it will be noted, are positioned toward opposite sides of the bunk. The op erating rods, are atopposite sides of the bunk, the swinging members 1212 are sup ported at opposite sides of the bunk,

leasing mechanism of the chockat the far-- ther end of the bunk from which it is located; Thus, if it is desired to release a chock at one side of the car and to discharge the log or other object from that side of the car, the operator would go to the opposite side of the car and move the long lever or handle 16, which releases 'the'swinging member 12 at the other end of the bunk body, being the opposite side of the ear from that on which he is standing, and the chock at that side of the car would be released and allowed to move down into the .3) In a log bunk, a body s 'eries of notches, a holding chock pivotally bunk body and into a position below the uppermost supporting edges of the bunk body, whereby any log or other object is free to roll off the end of the bunk.

It is intended that when the offset portion 15 of one of the operating rods 13 is turned downwardly so as to move the swinging member 12 outwardly and to hold it there, that said offset portion 15 shall be at such an angle to said swinging member 12 that the latter cannot move back and re lease the chock until the operating rod is turned. The angular engagement betweenthe end of the swinging member 12 and the lip 11 of the chock 9-is such that when said operating rod is turned, the swinging member 12 is automatically forced back, as shown in Fig. 4.

\Vhile I have shown and described but one embodiment of the invention, I am aware that changes can be made therein without departing from the spirit thereof, and I do not, therefore, limit the invention to the particular form here shown for illusposed supporting or hearing seats therein, a

holdingchock pivotally mounted therein and movable bodily to different bearing seats,

"and a-holding member for holding said chock inoperative position in any of said locations. j provided with mounted in said notches and movable bodily to different notches to change its operative location in said body, and a 'holdlng member; forfholding said check in operative position in-said body.

4. In a log bunk, a body, a pivotally mounted holdmg chock therein and adjustableto' different pivotal locations, an operating'-. 'm echanism, operable from the end of the-body of the bunk, for releasing said check, whereby otal bearing.

,5. In a log bunk, a body provided with oppositely disposed supporting or bearing. seats, a pivotally mounted holding chock with supporting trunnions adapted to said seats and movable upon its pivot-bearing to a position below the supporting s11" face of said body, and a holding and tripping mechanism operable from the opposite end of the bunk body.

6. In a log hunk of the character referred T it can be moved on its pivto, in combination, a bunkbody having oppositely disposed bearing seats, apivotally mounted holding chock with trunnion like members adapted to move upon its ivot bearing down into said body, said choc being movable bodily to different bearing seats, a movable part adapted to engage and hold said chock in its up or operative position, and an operating member for moving said movable part.

7. In a log bunk of the character referred to, in combination, a bunk body, a pivotally mounted holding chock. adapted to move upon its pivot bearing down into said body, said chock being adjustable to difierentpivotal locations, a movable part adapted to engage and hold said chock in its up or operative position, and an operating member for moving said movable part.

8. In a log bunk, a bunk body provided with series of oppositely disposed supporting notches or seats, a holding chock pivotally mounted therein and adjustable to dif-,

ferent locations therein, a movable part for holding said chock in'its up or operative position, and operating mechanism for'moving said part.

9. In a log bunk, a bunk body provided with series of oppositely disposed supporting notches or seats, a holding chock pivotally mounted therein and adjustable to different locations therein, a movable part for engaging and holding said chock in operative position, and an operating rod extending to the opposite end of said body for moving said part. v

10. A log hunk of the character referred to comprising in combination a bunk body of hollow construction with longitudinally extending open' g in its upper side; bracket members havin corrugated upper edges mounted op si e each other ad'acent said opening, a c 10Ck\ member pivotally supported through saidopening and upon said bracket members and adjustable to different positions thereon, said chock bein adapted to move upon its pivotal mounting down into said bunk body, a movable member adapted to be moved into holding engage ment with said chock, and an operating rod for moving said movable member into engagement with said chock, substantially as described. v
