DOOR FASTENER.

Application filed .Tune 14, `1926. Serial No. 115,864.`

This invention relates to` door fasteners, and more particularly for swinging doors l such as are `used at the rear of closed bodies for commercial vehicles.

In the present disclosure, the fastener is applied to a double door construction, in which the doors swing loutwardly for access to the interior of the body or compartment. The objectfof the invention is to provide a secure fastening for the doors at center, top and bottom and so operating as to draw the doors tightly together in a rattle-proof and weatherproof closure.

In the accompanying drawings,

Figure l is a rear view of a vehicle showing a typical installationY on the doors.

Figure 2 is an enlarged detail view show# ing the casing of the fastening mechanism as it appears from the inside of the compartment.

Figure 3 is a view in horizontal section through the fastener' as `taken on line 2'3--3 of `Figure 2. l

Figure 4: is a view in crossseetion taken on `line L -4: of Figure 3.

Figure 5 is a detail view in sections taken on line 5 5 of Figure 4, showing the spring finger acting on the bolt plate; and

Figure is a perspective view of the operating handle and arms for padlock.

As shown in Figure l, the body or compartment A of a closed vehicle for commercial purpose, is of the usual frame construction, and provided with a rear opening closed by two doors B-B which are hingedto opposite sides of the door frame, and swing together in substantial abutting contact at their edges. As is usual in door construction, the top and bottom rails a are recessed so that the doors close flush therewith, and one door (on the right, Figure l) has a marginal strip 7) which overlaps the edge of the opposite door whenthe two are closed.

The fastener consists in general of a pridoor to the outside thereof.

tion l, which is somewhat greater than a Within the bolt casing Il"L is the bolt plate consisting of a sector of a circle of substantially' the same contour as the casing sec tion. This plate is mounted on a simulare bushing G, having a square bore therethrough, said 'bushing bein g j ournaled at the geometric center of the bolt casing and having an er@ tension passing' through a hole bored in the n A Int-o the bushing 1s inserted the square shank "7 of a T-handle 7. About the periphery of the bolt plate 5 is a 'Iiange o, said plate lying close to the base plate 2 of its casing andthe flange extending at right angles toward the cover 3 as shown in Figure 3.

The forward end of the fiange 5 is beveled on its inner face 'to form a cani surface 5').

rFhe bolt plate is rotated in a clockwise di rection through an arc of 900 from a position in which its straight line edge is vertical and flush with the opening along the edge of its casing, to a position inwhich the saine edge horizontal. These positions of the plato are also determined by the IMfhandle 7 (Figure (i), whichstands verticai and horizontal in corresponding plate.` l

In order to restrain the movement of the plate, a spring finger 8 is mounted within the casing section lL and extending obliquely to the .radius thereof. This spring linger is riveted at its inner end, and provided at its outer end with a depressed lug 8". At points along the edge of the iange 5 are formed notches 9, 9, spaced 90o apart, and corresponding tothe extreme positions of the bolt plate, as shown in. Figure 5. In this manner the spring finger exerts a yielding pressure on the plate in its movement, and also engages the two notches 9, 9, at each end of its 1novement in both directions, thus making it necespositions of the bolt y lease the plate from either position.

fil

The smaller section 1b Vof the casing has already .been identified as the keeper, and into which the boltplate is rotated to effectthe fastening of the doors. The plate engaging member of the keeper is a roller 10, jourl nailed on the outer wall or cover plate 3 of the casing section, by means of a journal pin 10a. The roller however clears the inner wall of the roller and theadjacent surface of the rkeeper' casing. The location of the roller is Vsuchthat its periphery lies in the pat-h of the inner face of the flange 5a of the plate, so that as the plate is rotated into locking position, the cam surface 5a at the forward end ofthe flange rides onto the roller, thereby drawing the doors together and prevents them from rattling or sagging, and otherwise providing a tight 'joint between the edges of the doors.

In addition to the'primary fastening member, are secondary or auxiliary closing members in the'form of rods 11,711, extending upwardlyy and downwardly in vertical directions and adapted to project at their ends beyond the edges of the door frames. These rods are pivotally connected to the bolt plate 5, by means of journal pins 12, 12, fixed to the plate on opposite'sides of its center and 180O apart.

These pins rotate with the plate through angles of 90, or 45l above and below'the horizontal. The pin 12 to the left of the center (Figure 2) rides in-a curvilinear slot 13 of 90 extent, formed in the cover plate 4 of the casing, whereas, the outer vertical edge` of the cover plate is cut away as at 14, 'to permit the right hand pin to shift. The outer ends of the rods 11, are supported in'angle plates 15, fixed lto the door near its top and'bottom edges, these plates having an outwardly bent fiange 15l with a hole therein through which the rods slide. By preference, metal strike` plates 16, are fixed to the door frame to contact with the end rods. In

. the drawings thefupper rod '11 only, is shown "complete, it being understood that the lower rod is a duplicate thereof. l Y v Associated with the T -handle 7 on the outside of the doors are two bars 17 and 18, the former being fixed in horizontal position to the door carrying the handle, by means of screws 17a and preferably counter-sunk in 'other when theV same are parallel and the holes 19, 19 register with each other.

Thus assuming in Figure 7 that the T-handle stands crosswise when the doors are fastened, the two bars 17 and 18, are brought together and a padlock c inserted through 'the registering holes 19, 19, thus locking the handle against turning. The movable bar 18 preferably carries a plate 20, havin" an outstanding lip 20L extending endwise rom the outer end, the pur )ose of this lip being to prevent the padlock rom marring the door as it would, if allowedto swing freely.

The details of the fastening device may manifestly be modified without de arting from the spirit` of the invention, an therefore II do not wish to be limited except in so far as the invention is specified in the appended claims.
