asslgnor to Truscon Steel Company, Youngstown, Ohio, aV corporation of Michigan Application october z3, 1933, serial No. giessen;v 4 claims. (Cl. zo-19l As is generally known, piers, and particularly those for large ocean-going steamships, are equipped with large doors along theirsides, the arrangement being such that as many may be opened as desired for the loading and unloading of the cargo, and likewise for passengers. Practically all the piers of larger size are of double deck or two-story construction, the passengers ordinarily passing between the ship and piers on the upper floor. It is also a fact that upon the departure or arrival of a. steamer there is a large assemblyof friends and relatives so that means must be provided to keep such persons within certain safety zones. l5 Heretofore it has been the practice to have wooden guards or fences that are placed across the door openings after the doors have been opened. These fences are removable and therel fore require storage-space, which is an important item on piers. A

'I'he object of the present invention is to provide a door structure which in its specific character is' peculiarly adapted for piers, and in which a guard is provided that is in effect a part of the door structure, thus making it possible to open the door and yet leave'a guard that will prevent persons passing'beyond a certain zone and being in danger of falling through or from the open doorway.V y

An embodiment of the invention, which at present is considered the preferable one, is illustrated in the accompanying drawings, wherein Figure 1 is an inside elevation of the door structure in its operative or entirely closed posi- Figure 3 is a detail sectionalview on the line 3-3 of Figure 1.

Figures -1Ii^to 14 inclusive are vertical sectional views diagrammatic in their nature, showing the different relations the door elements may be caused to assume.v

The door structure and its operating means in its general make-up, and save for the modifications hereinafter explained in detail, correspond to the disclosure in Letters Patent of the United States granted to David H. Morgan, No. 1,789,189, January 13, 1931, and therefore reference may be had to that patent fo'r a more specific disclosure, particularly'of the operating mechanism.

Using the same reference letters as appear in that patent to designate generally corresponding parts, the lower leaf ofv the door is shown at A, and is adapted to register with theupper door leaf B by a sliding movement accomplished through the movement of the leaf A upwardly behind the leaf B and guided by the members C carried at opposite sides of the leaf B. The upper leaf B has a, hinge `mounting at D at the top or lintel portion of the doorway, so that when the two door leaves are telescoped, they are free to swing together inwardly and upwardly to a fully open position.

Considering now generally the operating mechanism, the same includes a pair ofglifting levers G, to the central portions of which the lower leaf is centrally pivoted as shown at H. 'I'he lifting levers are provided at their ends with rollers 3 that are adapted to travel in trackways 5 whose upper portions curve rearwardly fromsa vertical to 'a horizontal relation. 'I'he lifting levers 4-G areelevated by cable chains1\pperating over sprocket wheels 8 carried by an overhead cross shaft 9.' Suitable mechanism, including a depending hand chain I6a, is provided for turningthe rock shaft, all of which may be as explained in the above-entitled MorganPatent No. 1,789,189.

In the present construction the lower leaf A of the door is divided horizontally into separable sections ISand I6 located edge to edge and movable either together or separately.

As perhaps best 4seen in Figure 5 the lower section I5 includes a frame having an upper horizontal bar l1, a lower bar I8, an intermediate bar I9, and end bars 20. Connecting the lower bar I8 and intermediate bar I9, may be upper section I6 ofthe leai A is illustrated, this section consists of an upper horizontal bar 25,

'a lower horizontal bar 26, end bars 21 and intermediate vertical bars 28. The spaceswithin these various bars may be closed by suitable panel plates 29. It will be noted that the end bars 21 project below the lower bar 23, as shown at 30, and by reference to Figure 6, for example, this bar 30 includes angle plates 3I having outstanding flanges 32 spaced apart and slidably em-A bracing the guide flanges 24 of the lower section I5. It will thus be evident that the upper section I6 can be moved upwardly and downwardly on the lower section, and when moved downwardly. the paneled portion 29 will occupy the otherwise open space between the bars I1 and I9 of the lower section, thus completely closing said lower section, or in other words, making an entirely closed leaf A.

In order that the upper section IB may be moved easily with respect to the lower section I5, it is suspended by cables 33,H shown particularly in Figure l, said cables passing over suitable pulleys 34 and having depending from their outer or free ends counterweights 35, which as v shown in Figure 3, are located in the same boxings and if the leaf A is at its lowered position whenV full as the counterweights W for the door structure as an entity (see Morgan No.1,789,189). Further- 35 more the lower frame bar 28 of the upper section Ii may be provided with suitable handles 36 for manipulating the section.

` It will thus be seenithat the upper section i6 may be individually andflowered with respectrto the-lower'sectionIlrof the lower leaf A,

the upper section is elevated, the lower section will constitute a guard across the doorway. With niay be in the form of a channel bar, and in the channel thereof, is secured by screws 31 or other suitable devices, a hand rail that projects above the bar I9. The lower bar 28 of the upper sec "tion I6 may be a channel bar also, and when the r therefore means are provided fordetachably'securing together the sections I3 and I3. To' this end there is journaled in the lower portion of the frame bars 2 Ica horizontal rockeshaft 33f'and secured to the ends thereof are collars `lil carrying latch hooks 4I. The depending extensions 30 of the upper section have at their lower ends inwardly'extending keeper lugs- 42 that are adapted to be overhung by the latch hooks Il when the two sections are together. The rock shaft is provided with suitable operating means. This may take the form of a hand lever 4I secured thereto, and if desired, a foot treadle M. A coiled spring 43, connected to the shaft and surrounding the same, serves to bring the latch hooks 4I to their operative positions when the shaft is released, and

the shape of the latch hooks is such, as. will be clear by reference to Figure "l, that when the upper section is moved downwardly, the lugs 42 will pass the hooks, forcing the same to one side until the hooks will engage over said lugs.

With this structure it will be evident that the door members may .be made to assume various relations. Thus, as shown in Figure 10, the two leaves A and B may be so extended as to completely close the doorway. If the sections I3 and I8 lare latched together, in their closely related positions, the door structure may be operated in the usual manner, or as disclosed in the Morgan Patent No. 1,789,189. That is to say the two sections I5 and I6 will first be moved verticallyv to a position behind the leaf B, as illustrated in Figure 1l, by the elevation of the lifting levers G, after which the upper ends of the levers moving rearwardly, will cause the leaves A and B to swing upwardly and rearwardly, as indicated in Figure 12, tc a fully open position, as shown in Figure 13. Whenever it is desired to use the lower section I5 of the leaf A as a guard, the door may be closed to the position shown in Figure l0, after which the section I6 is unlatched from the section I5 and raised to a position behind the leaf B leaving the lower section I5 across the door opening,

`where it serves as a guard, as shown in Figure 14.

or removable guards that must be put in place and taken away and stored. The structure moreover is simple and the'guard is an exceptionally ef'- fective one in that there is no dIlger of its displacement by lateral pressure when it isin place and in action.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:
