z//z'ewgea'e/s BY @n ATTORNEYS Patented May 9, 1944 UNITED STATES PATEN TfoFFlcE `TRUCK s'rANCrmm Y William E. Stevens, Marion,Y S. C. Application october 13, 1941, serial No. 414,843 Y Y s claims. (o1. 28o-145) This invention relates to improvements in truck stanchions. v i

The object of the invention is to provide a truck stanchion which can be released from the cab of the truck and allowed to swing downwardly so that.1 it does not interfere with the unloading from the side ofthe body of the truck.

Another object of the invention is to provide a main locking'means for the stanchions 'and an auxiliary locking 'means for the main locking means, whereby the stanchions can not be accidentally released by the operation of the main locking means.

A further object of the invention is to provide a stanchion which is held in a vertical position and rigidly locked against any movement caused by the engagement of the logs or the like therewith.

A still further object of the invention is to provide a simple and effective main and auxiliary locking means having certain details of structure and combination of parts hereinafter set forth.

In the accompanying drawings,

Figure 1 is an end View of a truck body, partly Y broken away, showing my device applied thereto;

Figure 4 is a sectional view, taken on the line 1 4-4 of Figure 1;

Figure 5 is a vertical sectional view, taken on the line 5-5 of Figure 1;

Figure 6 is a sectional view, taken on the line 6 6 of Figure 3. 1

Referring now to the drawings, I and 2 represent two L-shaped angle irons supported upon the body of the truck in any desired manner, and having at their ends transverse bolts 3, extending through the vertical portions 4 and 5 of the angle irons, the same being spaced apart, as clearly shown in the drawings. Mounted on the bolt 3 is the stanchion 6, which is free to rotate on the bolt and to swing downwardly at an angle, as shown in dotted lines in Figure 1 of the drawings. Extending through the vertical portions 4 and 5 of the angle irons, on the inside of the stanchion 6, is a bolt l, which limits the inward movement of the stanchion, as clearly shown in Figures 1 and 2 of the drawings.

fil

drawings, to engage the lower end of the stanchion 6 below the bolt 3, whereby'the stanchion is held rigidly in a vertical position against the bolt l. VThe shaft 8, on Athe outside of the vertical portion 5 of the angleiron',` has .rigidly 'secured thereon a sleeve I0, provided with two diverging arms'A II yandl I2. Securedto the arm II2 `is an operating rod I3, which may extend or vbe connected to operating'means in the cab of the truck. 'The particular means of operating the rod I3 forms no part of this invention; and, therefore, the same is not shown. Extending throughv the vertical portions 4 and 5 of the angle irons is a shaft I4 having a collar I5 and surrounding the shaft between the collar I5 and the vertical portion 4 of the angle iron is a spring I6, which normally holds the shaft inthe position shown in Figure 3 of the drawings. The shaft I4, on the outside of the vertical portion 5, is provided with a collar II which limits the inward movement of the shaft. The shaft I4, beyond the collar I1, is turned laterally, as indicated at I8, and has its free end turned inwardly at I9, and passes into an opening 20 in the vertical portion 5 of the angle iron.

The shaft I4 is moved longitudinally by any desired means which may, or may not, extend to the cab of the truck. The inwardly turned end of the shaft I4 engages the arm II of the shaft 8, and prevents the shaft from being rotated by the rod I3. The parts being in the position shown in Figures 1 and 2| of the drawings, the

-stanchion is held in a vertical position. In the movement of the cam to the position shown in Figure 2 of the drawings, the cam rocks the stanchion on the bolt 3, forcing it over against the bolt l. When it is desired to release the stanchion, the shaft I4 is moved longitudinally bringing the end I9 out beyond the arm II and the cam can then be moved by the rod I3 to the position shown in Figure 2 of the drawings, which allows the stanchion to swing outwardly in the position shown in dotted lines in Figure 2 of the drawings.

Having thus described my invention, what I claim is:

f 1. In a device of the character described, a pair of spaced apart support members, a pivot element mounted transversely of the said members, a stanchion mounted to pivot on the said pivot element so as to provide a relatively short portion inwardly of the pivot and a long body portion outwardly thereof, a shaft mounted transversely of the support members below the stanchion pivot and spaced horizontally therefrom, a round cam element xed eccentrically on the shaft, the said cam being disposed for turning movement to bear against the short end of the stanchion to hold the body in upstanding position and to an angular position out of the path of movement of the short end of the stanchion to allow the body to swing outward, and lever means secured to one end of the cam shaft for selective operation of the cam.

2.- In a device of the character described, a pair of spaced apart support members, a, pivot element mounted transversely of the said members, a stanchion mounted to pivot on the said pivot element so as to provide a relatively short portion inwardly of the pivot and a long body portion outwardly thereof, a shaft mounted transversely of the support members below the stanchion pivot and spaced horizontally therefrom, a round cam element fixed eccentrically on the shaft, the said cam being disposed for turningmovement to bear. against the short end of the stanchion to hold thev body in upstanding position and to anr angular position out ofthe path of movement of the'short end of the stanchion to allow the body to swing outward, a pair of levers secured to one end of the cam shaft and extending radially therefrom in diverging relation, an operating member pivotally connected to one of the said levers, and a spring pressed .locking member normally disposed to ob.-

struct movement of the other lever to preclude accidental stanchion releasing movement of the cam. Y

3. In a device of the character described, a 5 pair of spaced apart support members, a pivot element mounted transversely of the said members, a stanchion mounted to pivot on the said pivot element so as to provide a relatively short portion inwardly of the pivot and a long body portion outwardly thereof, a shaft mounted transversely` of the support members below the stanchion pivot and spaced horizontally therefrom, a round cam element fixed eccentrically on the shaft, the said cam being disposed for turning movement to bear against the short end of the stanchion to hold the body in upstanding position and to an angular position out of the path of movement of the short end of the stanchion to allow the body to swing outward, a pair of levers secured to one end of the cam shaft and extending radially therefrom in diverging relation, an operating member pivotally connected to one of the said levers, a transversely slidable locking member having one end dis--
