(ci. zo--isi 'I'he present invention relates to' that type of door for steam-ship piers and the like. in coni nection with which a barrier or guard must be a employed at times towprevent persons passing through thedoorway when the door is opened and may be said to be of the general typeA disclosed in an application for patent filed by me October 23, 1933,-Serial No. '694,896.

The object of the pres'ent'invention is to provide a guard or `barrier that is supplemental to the door structuref'andv is so constructed and equipped that it can'be carried by the same and` thus deposited out. of, the waywhere it will occupy very little space and that space being otherl5 wise unusable, lor it'can -be left in an operative position across thelower portion of the doorway position.

The door structure as a whole may be ofthe. V4.0 type shown in the Patent to Morgan, No.

v 1,789,189, dated January 13, 1931, and therefore j it is believed .to be unnecessary to go into details l as to the structure and the operating mechanism therefor. It is believed therefore lsumcient 45 `to explain that va framed doorway is provided that'is adapted to be'closed by a vertically movable door. This door ,includes an ,upper leaf II hinged at its upperl end, as shown at I2.- and adapted to swinginwardlyl and upwardly from a `150 vertical closed position to a 'substantially horizontal opened position. -A lower leaf I 3 is slidable betweena position V belowthe upper leaf to A*mwa-position behind the same, and. thence to be Y swung with the upper leaf to said horizontal or f' in tracks I8 that are arranged vertically on op- 45 Aposite sides of the doorway and are turned rearwardly at their upper ends, as illustratedl at I9. The lower leaf Il ispivotaliy journaled as indicated at 20 to intermediate portions of the lifting levers. f 'K 10 As shown' particularly in Figure 3, .the lower leaf Il when in its lowered position. has its sides engaged in vertical guideways 2I, so as to prevent the lateral displacement of the leaf when in its active position.

l For the purpose of providing a barrier across the lower portion of the doorway to prevent ingress and egress therethrough when the door is opened, a guard Amember 22 is provided,- which in the present construction is a unit in addition 20 to thecomplete door structure. This guard may be in-the form of a light frame 23 constructed of aluminum, providing panels in which suitable netting 2l may be placed. This netting, asvillustrated inV detail in Figure 5 is'held by 'suit- 25 able hooks 25. 'I'he upper edge ofthe barrier member may have a rounded hand rail` portion 26.- As shown in Figure 3 the end bars of the guard rail frame' are extended as shown at 21 and have offset flanges 28 that are slidably en- 30 gaged in the guideways 2|. 'Ihese guideways preferably terminate at the top of the lower guard member is alongside the -inner side of the same. Means are provided for detachably coupling the guard member 22 to the lower leaf I3. 40 This means in the embodiment shown, includes a rock shaft 29 .iournaled in the lower leaf and carrying a plurality of inwardly and upwardly inclinedv latches III which are adapted to detach# ably engage the undersides of inset portions 3| 45 of the guard rail plate `26. An upstanding lever I2 aords convenient'means for operating the rock shaft, and a spring Il, connected tothe rock shaft, urges the same in a direction to proiect the latches inwardly, and therefore into operative relation to engage thevguard member.

' 'It isbelieved'that the operation of the structure can now be made clear. When the door is closed, the latchesv ll,- carried by the lower leaf,

engage under the handlrail or upper 1 end of 55 the guard member 22. If the door is operated in the normal manner', when the lower eaf is elevated, it will carry lthe guard member with it, as indicated in Figure 8, and a continued movement of the door to fully opened position carries the guard member to a point above the door, where it is out of the way and Aoccupies space that is ordinarily unusable. It will thus be seen r `that for normal purposes, the guard moves with the door and in no manner interferes with the latters movement. If, however, it is desired to place an obstruction across the lower part of the doorway to prevent ingress or egress of persons; then the guard member 22 is unlatched fromthe lower leaf by swinging thelever 32 outwardly,.

carrying the latchesl 30 to positions where they will be disengaged from the guard. If now the door is operated, the guard remains across'the lower part of the doorway, while the door moves in its normal'manner to any position between a partly and completely opened situation.

Whenever it is desired to -remove the guard, it is only necessary to lower the door, whereupon lthe latches will automaticallyv re-engagethe guard and thusA connect it to the lower leaf.

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 beunderstood that various linut ci! the guard.

be carried with the door section when the same is elevated, means offset laterally at the ends of said guard -for substantially embracing the ends oi' said door section and having ilange portions located within said guide members where- 4by the guard is guided by the same means which guides the door .section when both are elevated and also positions the guard in the doorway when the door alone is elevated, and means for detachably interconnecting the guard and door sectiOn.

2. In combination, a` doorway including guide y means at the opposite sides thereof, a door section slidable in said guide means, means for counterbalancing said door section arranged a't one side of the normal plane of saiddoor section, and a guard located at the opposite side of the normal plane of said door section, and means f or connecting and disconnectlngthe guard from said door section whereby the guard may be left in a lowered position between said guide means across the doorway orvmay be elevated with said door section, said guard member having side frame portions vextending across the ends of the door section and having oilset terminal portions engaging in said guide means.

3. In combination, a doorway including guide means, a door slidable in the guide means, and

a doorway guard normally offset to :me side f the door and having means extending across the edges of said door section for enteringsaid guide means whereby the guard and door ,may move in the same guideway, means ifor connecting and disconnecting the guard and door for simultaaeous or separate movement, said guard comprising a frame provided with a hand rail at the top thereoi', said hand rail deilning the upper -DOUIS J.
