METAL ROLLING SHUTTER AND DOOR.
Application filed January 6, 1923. Serial No. 611,161.
To all whom it may concern:
Be it known that I, MILTON L. CORNELL, a citizen of the United States, and a resident of New York, in the county and State of New York, have. invented certain newand useful Improvements in Metal Rolling Shutters and Doors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
' This invention relates to metal rolling shutters and doors, and more particularly to such doors as are located on exterior openings to buildings, piers, boats, etc., and therefore exposed to the elements. These doors heretofore have usually been made of galvani'zed steel slats or corrugated sheets. The bottom of the doors are subject to unusual 9 conditions due to collectedrain water, sea water, banks of snow, etc., which render the bottom ,foot or two subjectto accelerated corrosion not experienced bythe upper portion of the door. The principal object of this invention therefore is the provision of means for rendering the lower portion of the door sufiiciently resistant to corrosion to substantially increase its life, and hence the life of the entire door, and to do this without substantially increasing the cost of manufacture.
These doors usually comprise a plurality of interlocking steel slats which form flexible curtains, and in carrying my invention 5 into effect with this form of door, I replace the lower steel slats hy a material of greater Weather-resisting, non-corroding properties.
A further ob'ect of the invention is the a provision, in a oor such as described in the preceding paragraph, of means for preventing electrolytic action between the dissimilar materials.
A further object of the invention is the provision of means for increasing the weather-resisting and non-corrosive properties 'of the lower portions of the usual guides in which the door slides. Other objects and advantages will in part be obvious and in part be specifically referred to in the description which follows:
i In the accompanying drawings, Fi 1 is a front elevation of a bodymg my invention.
door em- Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1. 4
Fig. 3 is a section taken on the line 33 of Fig. 1.-
Fig. 4 is an enlarged section through a Referring to the drawings, there is shown a flexible door curtain 10 of a usual type fixed at one end to a shaft 11 revolublymounted in. supporting brackets .12, said curtain being adapted to be raised or lowered either by handles on the bottom bar, or by the shaft 11 which may be revolved by a chain 13 running over a sprocket connected through gears in usual manner to the end of said shaft. The curtain may be composed of a series of interlocking, horizontally-disposed slats, as shown on a large scale in Figs. 4, 5, and 6. At its lower end the. curtain is provided with a rolled steel beam or bottom bar-which may be a single right-angle bar 14 as in Fig. 4, or the double right-angle bar 15 as in Fig. 5. The
curtain is guided in its vertical movements by the usual channel shaped bars 16 in which the sides of the curtain extend and operate.
Where the slats are of galvanized steel andthe bottom'bar and guide-bars are ofthe usual black steel painted, it is found that the lower foot or so of these members above the ground is rapidly corroded and destroyed, for the reasons hereinbefore referred to. To obviate this condition, I substitute for a number of the usual steel slats,
at the bottom of the curtain,slats 20 com- I posed of a non-corrodible metal, such as bronze, brass, zinc, or aluminum. Where these doors are subjected to frequent use and the lower slats are of brass, bronze or other copper alloy, the zinc coating of the galvanizing on thelower steel slat, where the latter joins the upper alloy slat, is liable to wear off, in which event the uncoated steel of this lower slat, and the connecting copper alloy slat, may be in contact and an electrolytic action may result, with a consequent hastening of corrosion of the steel.
To avoid this, I interpose an insulating slat,
'as indicated at 21, between the adjacent slats of the upper and lower series, and
22. This slat maybe of zinc, aluminum,
' readily form, greatly delay any electrolysis, but such insulating slat is necessary only where the lower slats 20 are of brass, bronzelor other copper alloy, or other metal which mayreadily hasten electrolysis in contact with steel. Similarly, where the lowest slat 2O joins the bottom bar 14 or 15, an insulating strip 23 of zinc, aluminum or hard fibre may be interposed. In addition,
' the bottom bar may be heavily galvanized.
the sides of the curtain in the guides. Such The bottom portions 25 of the side guides also will preferably be coated with zinc as indicated at 26 in Fig; 1, as a further protection against corrosion of these parts. This coating is preferably put on by the hot dipped process, but any other well' known' method of zinc coating steel may be used. As the curtain does not fit closely in the guides, the zinc coating should be the only insulation necessary at these places.
Each alternate slat is usually fitted at each end with an end-lock 30, so that at least one edge of each slat is held at both sides against lateral movement. These end-locks serve also to prevent contact and friction of end-lock is usually a casting, in which case the skin which is formed thereon in the casting process serves to resist corrosion. It is often desirable that the material of the end-locks be the same as that of the slats to which they are fastened, or of some insulating material, to prevent electrolysis. These end-locks may be fastened to the respective slats by rivets 31 passing through flanges 32 integral with the locks. The rivets should be made of heavily galvanized steel or may be of the same material as the slats through which they pass, or of some insulating material such as Z1110 or aluminum, to prevent electrolysis.
The hereinbefore described structure provides a durable door or shutter in which the bottom parts wear lon er than the upper parts and thus greatly increases the life of the door or shutter-as awhole.
- 'I have here shown and described my in-i vent1on 1n connection with a door or shutter, the curtain of which is made up of a plurality of interlocking slats, but such curtains in some cases are also made up of single corrugated sheets, and it willbe understood that my-invention is equally applicable to curtains made up in this way.
- .It will be understood that various changes and. modifications may be made within the slats being formed of a relatively'corrodible metal, and the lower slats being formed of a metal of relatively non-corrodible quality.

5. A rolling door or shutter composed of a plurality of interlocking slats, the upper slats thereof being formed of corrodible metal and the lower slats thereof being formed of non-corrodible metal, and a slat of insulating material connecting said upper and lower slats.

A rolling door or shutter composed of a plurality of interlocking slats, the upper slats thereof being formed of corrodible metal and'the lower slats thereof being formed of non-corrodible metal, insulating material connecting said slats of different metals, a. bottom bar connected to the lowest slat, and insulating material between said lowest slat and said bottom bar.
8. A rolling door or shutter composed of a plurality of interlocking slats, the upper slats thereof being formed of corrodible,
and lower slats, a bottom bar connected to the lowest slat, and insulating material between said lowest slat and said bottom bar.
9.

10. A rolling door or shutter composed of a plurality of interlocking slats, the upper slats thereof being formed of com-edible metal and the lower slats thereof being formed of non-corrodible metal, a. slat of insulating material connecting said upper and lower slats, a bottom bar connected to the lowest slat, insulating material between said lowest slat and said bottom bar, side guides of corrodible metal in which said 1 shutter operates, and means for rendering the lower portion of said guides non-corrosive.
In testimony whereof I afiix my signature.
