The present invention relates to new and useful improvements in end gates for trucks and more particularly to an end gate for use with open or other type of truck or vehicle bodies and embodying means for adjusting the height of 'the end gate according to the size of the vehicle body.

An important object of the invention is to provide an end gate composed of stationary side panels and sliding center panels or doors for closing a central opening in the end gate.

Another object of the invention is to provide an end gate which is swingable on hinges at one side of the truck body whereby the entire end gate may swing inwardly of the truck, when desired.

A still further object is to provide a device of this character which is simple and practical in construction, efiicient and reliable in operation,

relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a rear elevational view, showing the sliding panels or doors open;

Figure 2 is a top plan view showing the sliding panels closed; i

Figure 3 is a rear elevational view ShOWlIlg'thG sliding panels closed and with parts broken away and shown in section;

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

Figure 5 is a fragmentary horizontal-sectional view taken on a line 55 of Figure 3;

Figure 6 is an'enlarged fragmentary-sectional view of the upper channel track taken on a line 56 of Figure 3; and

Figure 7 is a perspective view of one of the locking bars for the doors.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numerals 5 and ii designate upper and lower channel-shaped tracks both facing upwardly, and to the ends of which a pair of stationary sheet metal side or end panels designated generally at l and la are suitably secured. Each side or end panel I and 1a includes an upper sheet metal panel 8 which is preferably bolted at its front surface, as at 8', to the upper track 5 and a lower 5, Claims (01. 296-51) sheet metal panel 9 which is welded at its rear surface to the lower track 6, and with the upper and lower panels overlapping each other and free at their adjacent edges to permit vertical sliding adjustment of the upper panel relative to the lower panel.

Hinges H connect the upper and lower panels 8 and 9 of side or end panel 1 to one side 12 of a truck body and with the lower track 6 positioned substantially close to the floor 13 of the body so that the upper and lower tracks 5 and 6 and the stationary side or end panels 1 and la may swing inwardly as a unit at one side of the truck body, as shown by dotted lines in Figure 2 of the drawing.

The outer edges of upper and lower panels 8 and 9 of .side or end panel la are provided with upper and lower vertical angle iron members It and Ma which are secured to the slats [5 at the adjacent side of the truck body by nut equipped bolts l6 the-nuts having eyes IT at their outer ends which pass through openings (not shown) in the slats to receive a locking rod "3 which passes downwardly through the aligned eyes to lock the free end of the end gate to the truck body.- A spacing strip 14b is secured between lower panel 9 and angle iron member l ia to compensate for the width of upper track 5 in order to aline the upper and lower angle iron members with each other. The angle iron members '14 are provided with vertically spaced bolt holes, 'as at It, through which the bolts H3 are insertable selectively for vertical sliding adjustment of the panels 1, 1a.

A pair of sliding doors are shown generally at 3- and 20, each sliding door including an upper sheet metal panel 2| and a lower sheet metal panel 22 having their adjacent edges positioned in overlapping relation to each other. Hanger hooks 21a are attached to the upper edges of upper door panels 2! and slide in upper track 5 to close the opening between side or end panels I and 1a and lower door panels 22 slide in lower track 6.

A pair of tubes 23 are secured in a vertical position to the outer surface of the upper sliding door panels 2| by means of metal loops 24 and a pair of rods 25 are secured in a vertical position to the lower sliding panels 22 by metal loops 26 and with the tubes 23 telescoping or sleeved over the upper ends of the rods 25. Coil springs 21 are positioned in the tubes 23 with their upper ends engaging a cross pin 28 in the upper ends of the tubes and with their lower ends bearing against the upper ends of rods 25 to hold the upper sliding panels 2| in a raised position for traveling in the upper track 5 while the lower panel 22 travels in the lower track 6. Set screws 31 hold the tubes 23 in vertically adjust-ed position on rods 25 to maintain the hangers H a in the upper track.

A locking bar 29 is provided for each of the sliding doors I8 and 2%, one end of the locking bars being pivoted adjacent the ends of lower track 5 for vertical swinging movement and the free ends of the locking bars are formed with a channel member 35 for entering the channel of the track 6 to engage the outer edge of the adjacent sliding door to lock the same in a closed position at the center of the gate and to close the opening formed between the stationary panels '5 and la.

By attaching the end gate in position to a truck body, as indicated, the sliding doors [9 and it close the opening between the stationary side panels '1 and la and are locked in closed position by swinging the locking bars 29 downwardly to engage the outer edges of the sliding doors, as shown in Figure 3.

When locking bars 29 are swung outwardly, the doors i9 and 2d are free to slide in front of the stationary side panels i and M as shown in Figure l, to open the doors, and the entire end gate may swing inwardly on hinges H against one side of the truck body by withdrawing the locking rod 18 from the eyes ill.

The upper panels of both the stationary panels 1 and la of the doors l9 and 28 being slidable vertically enables the vertical adjustment of the end gate to a desired height to lit in various types of truck bodies.

In view of the foregoing description, taken in conjunction with the accompanying drawings it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein describedand the scope of the appended claims.
