June 14, 1932. R. L. HEWITT TOGGLE FASTENING APPLIANCE FOR DOORS 2 Sheets-Sheet 2 Filed NOV. 21, 1930 Z mmyro m ATTORNEYZ Patented June 14, 1932 Hair ROY L. I-IEW'ITT, OF COLORADO SPRINGS, COLORADO TOGGLE FASTENING APPLIANCEFOR DOORS Application filed November 21, 1930.

My invention relates to improvements in fastening for doors and their hinges in which I have a detachable hinge on each of the opposite edges of the door allowing it to be released at either of the swing sides or entirely removed at the attached hinged edge or the edge at which two doors are connected; and

the objects of my invention are, first, to provide hinges that are detachable from the door by the operation of a toggle fastening appliance; second, to provide a toggle latching means by which two doors or members may be securely and detachably connected; third, to provide means for removably securing a door or gate to a truck box or wagon box; fourth, to provide means securing walls cletachably together to form enclosures.

I attain these objects by means of the mechanisms illustrated in the accompanying draW-.

ings, in which Figure 1 is a diagrammatic elevation of a three piece endgate for a truck vehicle; Fig. 2 is a diagrammatical elevation of a part of one side of the side wall A of a truck vehicle bed and showing the lower part of the endgate detached at its top connection and hinged at its lower connection; Fig. 3 is a diagrammatic elevation of similar construc-.

tion of Fig. 2, but with the gate member C, released at its lower edge and hinged at its top edge and swung out at its lower edge; Fig. 4 is a sectional plan view of a part of the door, wall and fastening appliance re leased; and Fig. 5 is a plan view similar to Fig. 4, but showing fastening appliance securely latched and forming a hinged, and tog le connection between the endgate and the bed or other inclosure.

Similar designating letters and numerals refer to similar parts throughout the several views.

The stublug 2 adapted to lit rotatably into the recess 10 and the clevis 4 adapted to secure it therein by means of the toggle lever or latching lever 5, constitute the pr1nc1pal appliances for securing doors in my invention.

The end door 0, herem described, represents the door appropriate for a truck for shipping coal or other treight material and Serial No. 497,112.

is appropriate to be supplied with a dump- 111 mechanism. The vehicle is not shown, as the fastening appliance may be used on other enclosures besides vehicle boxes. But the application of my invention is illustrated herein as more appropriate for a three-door end for freighting truck vehicles.

In Figure l, 0 represents the lower end door hinged at .its top edge and at its bottom edge by means of the toggle fastening appliance illustrated in various positions in Figs. 1,2,3, 4 and In Fig.2, is shown said door C, released at 1ts top and is allowed to drop down to an almost horizontal position, where it may be sustained by chains or other means, and in Fig. 8, the said door C, is secured at its upper edge in a hingedcondition, and is released from its former hinged condition, at its lower edge and is allowed to swing open backwardh and upwardly from the lower edge of the bed ortbox to allow a loose load, as coal, to slide on If the door C is held in the position shown 111 Fig. 2, it is appropriate for carrying long material, as'luinber or metal rods.

Some coal trucks now are adapted to carry as much as ten tons of coal at a load, and thls requires an end door at least seven feet by four or five feet, and such a door is too heavy to be safely handled by one man. This invention provides a three-piece door as illustrated, and its mechanism obviates the need for itto be entirely released or dismounted from the truck box at any time of its operation, so that one man can manipulate it for any desired emergency as shown illustrated. v

The doors E and D are hinged so as to swing thI'GQfOllIthS of a circle or about 270 degrees and may be secured open and against the outside of the box when not in use. l/Vhen brought together, as shown in Fig. 1, they are securely latched by hooking the bow of the clevis 4, over the projecting lug 7 and securing the latching lever 5 against the door D, while the toggle position of the pins 14 and 18 with thelug 7 which are out of a di rect line as shown in Figs. 4 and 5, will allow the resiliency of clevis 4 to preventpivot 14 from going past dead center.

Also this manner of mounting the doors E and D, provides a stiffening brace to prevent the walls A from careening or spreading. In Fig. 2, a view of the latches shown on D and E in Fig. 1, is omitted to show a form of E to abut inside of the walls A. In Fig. 2, the numeral 16 represents the top surface of B.

Figures 8, 4 and 5, illustrate the mechanism of the latching lever in detail. On the body A, is securely mounted, by welding or otherwise, a member carrying two projecting lugs 3 forming therebetween the recess 10 adapted to receive the stub-lug 2. The stub-lug 2, which is rigidly secured to the door by welding or otherwise, is pressed into said recess 10 by the clevis 4 encircling it and riding in the provided annular groove 17 in the stub-lug 2, and said clevis is secured to the part 12 of the latching lever 5, by means of the clevis pin 14 which latches in toward the wall of A past a direct line of the contact of the clevis 4 with the stub-lug 2 and the hinging of the lug 11 with the latching lever 5 so that the spring of the stretching of the clevis 4 tends to hold said lever in place.

he handle 6 is shown in Figs. 4'and 5 as projecting outwardly from the projected line of the latching lever 5 so as to provide a convenient handle to be readily grasped, and these latching levers are provided with safety pins 18 to insure their retaining their clevises in place. In the doors E and D it will be noticed that the hinge members 21 are rigidly secured to the respect ve doors and the hinge members 20 are rigidly secured to their respective walls, and in a manner to allow them to be swung outwardly agalnst their respectlve walls or entirely dismounted.

B represents the floor of the box and 1 represents the head or enlarged outer end of stub-lug 2. InFig. 2 is shown the lugs 3 formed on a rectangular piece, and in Fig. 3 they are shown on a bar 15 supposed to be welded to the frame of A. This shows the two ways I have had this construction formed and I prefer the form on the bar 15,

" but they may be secured to the bar 16 and the wall A, as in Figs. 4 and 5.

' The pressure side 13 of the stub-lug 2 is the part of contact with the clevis 4 and holds stub-lug 2 in place in the recess 10 and thus forming a complete bearing for the rolling of said lug as it hinges the door to the body of the box.

The hinges 8 on the door E and the hinges 9 on the door D, are not claimed'as novel, in themselves, but appropriate in this form of construction with the addition of the seeuring means 18 and 22, or similar appliance.

Having thus described my invention I claim 1. A toggle fastening appliance for doors,

comprising in combination, a journal bearing secured to the wall of enclosure, a journal operatively mounted in said bearing and secured rigidly to a door and a toggle clamping means releasably securing said journal in said bearing, said means comprising a clevis member having its ends pivotally pinned to a toggle lever and the bow of said clevis member operatively enclasping said journal to draw it within said bearing.
