Antique Art Nouveau Expandable Cast Iron Bronze Folding Book Rack 9798 (?)
My brother is moving out of his apartment and has stuff for me to sell.  I remember this bookend in my late parents' house in the 1960s.
The bookends measure 6" wide and 4 1/2" tall.  On the sliding rack, the outer bars are 5" apart.  The rack starts at 13" and expands to any length up to 23.5".
Weight: 2 pounds 7.1 ounces (empty)
The embossed number is similar to those found on racks made by the Judd Company.  The last number (8?) is hard to decipher on both bookends.
A magnet adhere to both bookends and the three inner sliding bars but not to the three outer bars and the beams holding the bars.
Bronze is usually nonmagnetic, but certain alloys containing iron or nickel may have magnetic properties.
Because of some glare of the kitchen lights, I added two photos on a black towel taken outside.
To be shipped USPS Priority Mail.  I selected the small flat rat box which will fit I ship the fastener in three pieces.  If I selected a 7"x4"x3" box, that increases the USPS postage 0.10 for NYC, .65 for Chicago, and .75 for LA.
I combine shipping.  You can request an invoice.  Or, if you pay shipping charges before I buy a shipping label, I will send a message with a plan for the service and package type and how to refund the savings.
Thank you for looking.

Judd Manufacturing Company’s roots date back to 1833 as a harness manufacturer
in New Britain, Connecticut.  The firm changed hands among family members and company names for a hundred years as it evolved into the J.H.Judd Co. of Wallingford, Connecticut.
In 1864, Albert, Edward and Hubert Judd moved the company to New Haven, Connecticut, then to its permanent location in Wallingford, Connecticut.  A few years later, Hubert Judd struck out on his own to start the H.L.Judd Company in Brooklyn, NY.  In 1886, H.L.Judd  took control of the Wallingford plant.
In the early 1910s, they began to produce a decorative art metal line of fine-quality sand castings in iron, brass and bronze.  Among these items were bookends and book racks, which were produced between 1910 and the late 1930s.
Judd identified their bookends with a 9000 series stock number.  The prefix “0” was used in front of the 9000 series number on iron castings only when the same design was cast in both bronze and iron.
