10 Claims.

This invention relates to improvements indoor mounting and operating mechanism and more particularly to a combined hinge andoperator for pivoted floors such as usedon refrigerator cars, trucks and the like, although obviously adapted for use with pivoted doors in many other situations.

I One object of the invention is to provide a mounting and operator of simple and rugged construction for that type of pivoted door which combines with the pivotal movement thereof a movementof bodily translation when forced to closed position such as to interlock the free edge of the door with the door framework to prevent opening of the .door, except upon proper manipulation of the operating means provided therefor.

Another object of the invention is to provide 'a combined'pivotal mounting and operator for a door wherein provision is made to compensate for such variations that may arise in service due to shrinkage or swelling or weaving of the structure to the end that accurate and complete closing and seating of the door will always be attained.

Still another object of the invention is to provide a combined hinge mounting and operator for a'door such that the same may be utilized as an adequate support for the hinged edge of the 'door when the latter is pivoted to swing about a horizontal axis along its lower edge and the door used as a loading or unloading platform, as for instance on the rear ends of trucks, vans or the like.

A further object of the invention is to pro-- vide a mounting. and operator of the character hereinbefore indicated which is comprised of minimum number of parts of such design as to v be easily and economically manufactured, the

same being of staunch construction and also readily applied in place.

Other objects of the invention will more clearly appear from the description and claims hereinafterv following.

In the drawings forming a part of this specification, Figure 1 isa side elevational view of a door with the improvements applied thereto,

parts being broken'out to better accommodate the figure on the sheet. Figure 2 is a horizontal, sectional view corresponding to the line 2'2 of Figure 1, the dotted lines indicating the.

position of the door hinge mounting and operator when the door is near closed position.

Figure 3 is an elevational view of the hinge mounting shown in Figure 1 but upon an enlarged scale to better illustrate certain details Y of construction, parts being broken out to better accommodate the figure on the sheet. Fig ures 4 and-5 are horizontal sectional views corresponding to the section lines 44 and 55 respectively of Figure 3. Figure 6 is a broken, elevational view illustrating a different embodiment from that shown in Figure 1 and wherein two doors are employed to close the' door opening. Figure 7 is a horizontal sectional view, corresponding to the section line 1-1 of Figure 6, one of the doors being shown partially open in dotted lines. Figure 8 is an elevational view showing another embodiment of the invention as applied to the door on the rear of a truck or van. And Figure 9 is a vertical sectional view corresponding to the line 9--9 of Figure 8., the dotted lines in this figure indicating the position of the door. and associated parts when employed for loading or unloading.

Referring first to the construction illustrated in Figures 1 to 5 inclusive, the invention is there 1 indicated as applied to a refrigerator car wherein ing. As there shown, the stile III has its door engaging face I3 undercut or inclined inwardly of the car so as to provide an acute angle with the outer plane or surface I4 of the car side wall. The stile II has its door engaging face I5 arranged parallel, or substantially parallel to the opposed face I3 of the other stile, that is, the face I5 forms an obtuse angle with the plane or outer surface I4 of the car side wall. As customary in refrigerator cars, a flexible backing or seal will be provided at the door joints, the backing shown being of well known form and comprising, in each instance, a strip of canvas I6 applied to the stile beneath which is a pressure bar or strip II working in a slot or rabbet I8, the pressure bar I1 being supported on a plurality of springs I9so as to afford a yielding surface for engagement with the adto provide a wedging joint when the door is forced home. At the upper and lower corners on the free edge-of the door, the latter is preferably provided with triangular plates 20-20 which are extended above and below the top and bottom edges of the door and cooperate with a guide plate 2| secured to the lintel and with the threshold of the door opening to insure proper positioning of the free edge of the door when forced to closed position.

The improved mounting and operator comprises, broadly, two hinge members designated generally as A and B, secured respectively to the iixed wallstructure and door, a combined hinge link and operator C; and pivot pins 22 and 23.

The two hinge members A and B, as shown, are applied to the adjacent edges of :the wall structure or stile and the door and the same are of complemental construction so that a detailed description of one will sufllce. Each of said members consists of a main plate or web 24 extending vertically and preferably of a height corresponding to two thirds or three quarters the height of the door with which employed. The same is secured to its support by a plurality of heavy carriage bolts 25-25 applied throughout the length thereof at suitable intervals. Formed integrally with each plate 24 is a plurality of hinge lugs or hubs 26-26, three of the same being shown on each of the members A and B in the particular construction illustrated, one each at the top and bottom and the other at the center. As will be understood, these hinge bulbs or lugs of the two plates A and B will be horizontally alined, as clearly shown. All of said hubs or lugs 23 are provided with vertically alined apertures for the snug reception of the two elongated hi'n'ge pins 22 and 23, the latter being headed at their upper ends as shown, to prevent loss thereof.

The combined link or yoke and operator 0 comprises a main plate or web section 21 and an operating arm 28 being extended lie the door when tion and as shown in the drawings. Said arm 20' ispreferably utilized alsoas a hasp, the same having an opening 28 therein near its outer end adapted to take over a staple 30 secured to the door, the staple being apertured as indicated at 3| to receive a suitable pin with usual lead seal or look to prevent tampering. To provide the requisite strength, the arm 28 is preferably ribbed as indicated at 32-43 and the width of the web section of the arm is increased'suitably where the junction is made with the main plate or web section 21, as shown in Figure 1.

On its inner side, the plate section 21 of the link C is provided with a plurality of integrally formed hinged hubs or lugs arranged in three sets. The upper set comprises hubs 33-35 and 38; the central or intermediate set comprises hubs 31-38-38 and 40; and the lower set duplicates the upper set. Said sets of hubs 34-40 are in duplicate sets horizontally opposite each other so as to cooperate with the two hinge members A and B and pins 22-23. Each pair of hubs 34 and 35 is spaced so as to receive therewithin the .corresponding upper hub 26 of one of the members A or B and the same is likewise true at the bottom of the mounting. Each of said hinge hubs 34 and 35 at both the top and the bottom is provided with a hinge pin opening 48 elongated in a direction parallel to the wall, for

in a direction so as to over- 28 integrally formed, the arm the latter is in closed posisponding to the diameter of the hinge pins so that each of the hinge hubs 38-31 and 40 is adapted function as a fulcrum upon flexing of the hinge pins between the sets of hinge hubs 28 on the members A and B and within which the pins 22 and 23 are snugly received, as previously set forth.

From the preceding description, it will be seen that the axis of the pivotal connection between the combined link and operator C and the hinge member A is at one side of the door joint and the pivotal axis of the connection between saidmember C and the door hinge member B is at the opposite sideof the door joint, said axes being parallel. With this construction, provision is obviously made for pivotal movement of the door 12 not only with reference to the supporting wall structure or stile II, but also a supplemental pivotal action with reference to the combined link and operator C. With this construction and assuming the door in closed position as shown best in Figure 2, the operation in an opening movement .is as follows. As the operatin handle 28 is swung outwardly about the pivot pin 22, the initial action on the door l2 .will be an outward movement of the hinge edge of the door due to the hinge pin 23 being swung outwardly by the operating handle 28 about the hinge pin 22 as an axis. Said initial outward movement of the door edge is relatively rapid and serves tov initially release the hinge edge of the door from the stile II. As the swinging movement of the handle continues, said outward movement assumes more of a movement of translation'of the door toward the right, thus pulling: the free edge of the door away from and releasing it from the stile 10, the movement of translation finally being sufllcient, as shown by the dotted line position in Figure 2, to entirely disengage the free edge of the door from the stile l0 and clear the door entirely from the door opening. Thereafter, the door may be swung freely by the grab handle 42 and the door finally positioned back against the wall of the car, as will be understood. In this connection, attention is directed to the particular formation of all of the hinge lugs on the member C, as best shown in Figures 2, 4 and 5, the same being suitably cut away, as indicated at 43-43 so as'to allow ample clearance for the vertical edge of the door when it is swung with reference to the operating handle 28 as illustrated in Figure 2, thus preventing any fouling of the parts during .the operation. In effecting closure of the door; the parts are brought back to the dotted line position shown in Figure 2. The free edgeof the door is then guidedinto the door opening while the handle 28 is being swung inwardly until the free edge of the door is moved inwardly as far as possible, being limited by the plates 20. As the handle "is then moved still further inwardly into parallelism but the aperture thereof.

with the door, the movementof translation toward the left as-viewed in Figure 2, will be com- .pleted and alsothe hinge edge of the door will be forced firmly into its fully seated position. When closed, it is obvious that the door cannot be opened except uponmanipulation of the operator in the intended manner.

By providing the slightly enlarged apertures in the hinge hubs of the members C and the fulcrum-forming openings ll in others, as previously described, it is evident that provision is thereby made for a reasonable amount of adjustment, horizontally, of the door with reference to the stile I I, this adjustment being accommodated by slight flexing of the hinge pins 22 and 23 between the fixed hinge hubs 26. In this manner, shrinkage or-swelling or weaving within reasonable amounts may be readily accommodated without in any wise impairing the efliciency or staunchness of the mounting as an entirety.

With the construction illustrated and described, it is evident that a minimum number of parts are required to provide both for the actual mounting of the door and for its operation. Furthermore, ample area is provided for attaching the hingemembers A and B to the door and wall structure and a powerful leverage may be exerted both in releasing the door and in forcing it home.

Referring next to the construction illustrated in Figures 6 and 7, two refrigerator car doors are there illustrated, it being understood that the mounting and operator for each door 2-H 2 will be the same as that previously described. Where two doors are employed for closing the opening, complemental keepers -5l will be applied to the lintel and threshold of the door, as shown, each of said keepers being provided with two oppositely arranged, laterally flaring recesses 52, each having a camming surface 53. Each door leaf H2 will be provided adjacent its free vertical edge with a rod 54 mounted in suitable brackets 55, the rod having its upper and lower ends extended so as to be received in the respective openings 52 of the keepers when the door leaves are moved to-closed position. As will be clear from Figure '7, referring to the dotted line position of the lefthand door leaf H2, the rod ends will be 'entered into the keeper slots 52 so as to engage behind the camming surfaces 53 and, as each door leaf is then forced home, the rod ends will ride down the camming surfaces 53 and force the free edge of the door inwardly to its proper final position, while the hinge edge of the door is being simultaneously forced home. In opening the doors, the same combined pivotal movement and movement of translation will take place as previously described for the construc tion shown in Figures 1 to 5. The rods 54 may obviously be used as handles or grips when swinging the doors.

Referring next to the construction illustrated in Figures 8 and 9, the door 2|! is there shown as made of sheet metalwith suitable rigidifying corrugations formed therein. The edges of the door are also preferably reinforced by an integral oifset flange 6|, the latter also serving to provide a weather joint where it overlaps the fixed wall structure 62 of the rear end of the truck or van. At its upper free edge, the door.

2|! is provided with a locking cleat or plate 63 riveted thereto on its inner side in such manner that when thedoor is in closed position as shown in Figure 9, the free edge of the door will be interlocked with the lintel section of the wall 62.

The end .sill of the truck. which also provides the threshold of the door opening, is preferably in the form of a channel as indicated at 64, the flooring being indicated at 65. 'In this arrangement, the hinge members A and B are or may be the same as those of the first described construction and secured respectively to the sill of the truck and lower edge of the door. The combined link and operator 0' is substantially the same as that previously described except that the operating handle 228 thereof is preferably centrally located and in addition, said member 0' is provided with a plurality of integrally formed stop lugs 66-66 arranged at suitable intervals therealong and rigidly braced, said lugs 66 being extended downwardly below the bottom edge of the main plate of the member C and adapted, when the door is swung open and inclined downwardly into platform position, to

engage the bottom of the sill 64 as indicated at I66. In this manner, the hinge edge of the door is rigidly supported and independent pivotal movement between the door and the member C prevented, inasmuch as the arm 2260f the member C will bear against the underside of the door when in the dotted line position shown. As will be obvious, the opening and closing of the door will be effected in the same manner as previously described and in addition, the mounting and operator provides an adequate support for the door, adapting the latter to be utilized when loading or unloading.
