I just purchased a house with an old pull down attic ladder patented on December 3, 1929. I found this date on a very dilapidated label on the right side rail of the ladder. Not much else was discernible except that it had the name _ictor. Perhaps Victor, but I cannot be sure what the first letter is. Please see pictures

The ladder will not pull up by itself and I have been attempting to repair it to no avail. the top rung of the ladder has a long spring attached to it just above a revolving drum which is attached to the door. Just below that is another long spring attached to the door. Down lower, on the third rung from the bottom is a wood screw eyelet. Somehow, a cable attached to the upper spring is supposed to pull the rest of the ladder up, utilizing the drum, and hold it in place while the door is closed up in the ceiling. The drum spins freely and does not appear to have a takeup spring inside.

In the past many of you have been able to find patent drawings with minimum of details. I am submitting this in the hopes that someone will be able to come up with a set of patent drawings for this pull down sliding ladder that has the cable configuration which I can use to repair this pull down ladder, or, if someone has a ladder like this and can send me pictures of the cable configuration, that would be the next best thing. Thank you in advance, to anyone who can help me.

Sincerely,

Jim Patrick

Post a better photo of the label.

Maybe we can discern the name of the manufacturer above the word "Victor." Also, the printing immediately below "Victor."

Did a little more research and discovered the manufacturer was Farley & Loetscher Mfg. Co. The small distance between the wall and ladder prohibit the taking of a better picture. Thank you.

Jim-
Maybe there was a spring (that has sprung)inside the cable drum to assist in its ascent

Found articles and ads in trade journals for Farley & Loetscher Presto Disappearing Sliding Stairway but seems quite different in design compared to what you have.

Could not find anything for Farley & Loetscher "Victor."

Did find a reference to "Victor." There is a Farley & Loetscher suspended stairway catalog page for sale on eBid.

When this page opens, click on the photo - the Victor is show lower right:

Yopu can chec the Patent Office Gazette for Tuesday, December 3, 1929, to get the actual patent number. Then it is easy to look up the patent information.

Using the issue date of December 3, 1929 and limiting the search to December 1928 and January 1930, and the search term "stair", I found Patent 1,737,799 at Google Patent

The pictures look like your stairway. A detailed description of how it works, along with explanation of the various tag letters, is in the Google page.

stair 3

That's it Thomas. Tomorrow, I will be re-routing the cables and I'm sure my stairs will work as intended. Thank you everyone. You are all amazing! Jim Patrick
