WHEELER GLASS & SHADES - Manufacturing Methods

On This Page:

Authenticating Manufacturing Methods & The ID Of Replacement Glass

There are basically three things to watch for when authenticating the glass found in smaller Wheeler shades, or other mirrored shades of these types.

  • Red lead backing on the mirror
  • A smooth lead appearance around the inner and outer edges of the shade
  • A heat ring close to where the bulb would have set
The red backing is not limited to Wheeler shades, as it was a manufacturing process that has been being used since the 1850's (maybe earlier).

Patent Information And Early Glass Silvering Methods

The first info I could find was the mention of a patent by the inventor DOMINIQUE DURAND of New York City in 1856. This is likely a hand written document being harder to find (I already downloaded the entire year of patents though), but it is mentioned in Durand's patent No. 123,247 Jan. 30th 1872

This is a good read as Durand is point to another patent (from another inventor) and explaining how it is in error in the makers methods of using shellac, in the place of varnish after the silvering.

Durand uses copal varnish (as it stands up to the heat better) and discloses his process of temperatures, mixings, etc. http://patentlink.antiquesockets.com/?123,247

If you read the patent, you will see that he then goes on to describe the red backing, that I see on all of my Wheeler glass samples.

Painted with "red lead ground in oil and thinned with spirits of turpentine" as also explained in the other patent.

The Walker patent that he only reefers to as "December 13, 1869" (but the patent office was closed on that day). The patent that he meant to refer to was patent No. 97,838 December 14th 1869 linked below:

Patent by Henry Balen Walker
http://patentlink.antiquesockets.com/?97838

So, with the above patent we have the entire process in detail, just should not use the shellac.

This patent was reissued by William Augustus Walker on July 18th 1871, after the death of Henry Balen Walker.

http://patentlink.antiquesockets.com/?RE4477

George W. Walker on May 19th 1879
http://patentlink.antiquesockets.com/?216587

Now using Varnish...

And before it dries to brush the back with bronze powder.

Walker had a method of heating the glass during the silvering process.

His invention of a steam table that he used for this heating process:

http://patentlink.antiquesockets.com/?108413

Another invention of a stool that he used in silvering was his patent http://patentlink.antiquesockets.com/?110408

Another patent from another inventor using copper in 1861
http://patentlink.antiquesockets.com/?33721

Red Lead Backing On The Mirror
As shown above, there were different methods through time of sealing and protecting the silvering on the back of the mirror glass. To this date all of the Wheeler shades that I have come across have all used the red lead backing.

Most times you can see some evidence of this backing, even if the mirror is in really good condition.
In these cases though you may need to look REALLY close between the glass pieces (as shown in some pictures below). You can also download a full resolution pdf of most of the images below which will also allow you to zoom in for a closer look.










Painted Gold "Smooth And Even" Lead

The next thing to watch for is that the lead molding around the shade is smooth and untouched.
It is not hard to compare the difference between a shade that never had it's glass replaced and one that has.
Even if great care was taken in replacing the glass, there will still be clear evidence that it had been tampered with.

Wheeler used soft lead that was smoothed and tooled using a rimming machine that rolled the lead around the edges to make the "Fellet-Bead".

The fellet bead is a diamond shaped leaf which holds the glass in place.
The lead was then painted and finished in gold.

If the glass ever cracked or broke and was replaced, there would be two things to watch for.

First the lead would be crumpled, dented and (or) no longer have the straight smooth factory edges shown below.

Second, there would be some paint loss (speckling). This would had been caused when the lead was bent open and the attempting to re smooth it. As you can see from the pictures below, it would be a real task to make the shade perfect again after replacing glass. This type of shade with the soft lead painted rim would NEVER be perfect again after having it's glass replaced(.)





Shown above is also the old patent for the diamond shaped bead (Pat. No. 268,063). The new patent no longer required the leaf to be soldered to the inner rim of the shade as those manufactured before 1889.



Heat Rings On The Mirror

All shades do not have heat rings, only the ones that received lots of use.
It is common enough to look for though.
If there is distress on the glass close to where the bulb or heat would have gathered, be sure that all of the glass matches. It is common where only one or a few pieces of glass were replaced, that the replaced glass would be missing or break the ring pattern.

Many times when glass is replaced, it is replaced with glass from another old broken shade.
While it might even be of the same type of glass, it would show by not matching completely when it comes to obvious patterns.

Wheeler Shade Patents And Product Examples





The earlier Wheeler shades styles (hard to come by) were mostly used for kerosene and gas.
As shown in the text (N.B.) directly above, the early Wheeler gas shades were sold for both gas and electric use.



Most times Wheeler shades will be marked with a brass sheet tag, which can contain different selections of patent dates.

The patent dates will normally pertain to either the method of holding the glass (the diamond shaped bead around the shade rim), the holding method used, or the reflecting technique (example the shape of the shade).


The shade shown above (Wheeler Style No. 414) uses three patent dates on it.

Sept. 27th, 1881 (Pat. No. 247,589) Reflection Method
Mar. 7th, 1882 (Pat. No. 254,522) Holder/Shade Support
Nov. 28th 1882 (Pat. No. 268,063) Glass Seating Methods (old Fellet-Bead)
Nov. 28th 1882 (Pat. No. 268,064) Soft Lead Seating


Cone, inverted and flat shades (made mostly for electric use), will normally be found with the patent dates of Nov. 28th 1882 (Pat. No. 268,063) the old patent for the lead beading and Oct. 22nd 1889 (Pat. No. 413,242) which was the new patent for the beading.

To be complete, there was a second patent on Nov. 28th 1882 (Pat. No. 268,064), that has to do with the soft lead that held the glass in place.

Here in this patent, Wheeler documents three other patents for reflectors and how their glass attaches.

These patents are William Marot Marshall of Philadelphia, Pat. No. 73,355 dated Jan. 14th 1868 for how glass mirror is mounted, Frederick Hartmann of Chicago, Pat. No. 155,085 dated Sept. 15th 1874 for a kaleidoscopic lantern and Samuel B. H. Vance of New York, Pat. No. 229,212 dated June 22nd, 1880 for a large reflector.

Miscellaneous Remaining Notes - Cleaning glass


Shown above, Wheeler gave safe instructions for cleaning silvered glass.
A dry cleaner is suggested called "whiting".

This is basically pumice sold for cleaning glass even today, but pumice itself is better to use because it is more abrasive than cerium oxide and whiting.
You can buy whiting here: http://angelgilding.com/A2505.html
You can but
pumice here: http://angelgilding.com/A2515.html

Another type of reflector to watch out for
Wheeler made what they called the Daylight Reflector.
This reflector was made of corrugated glass and were made of different sizes to fit into a regular house, store, cellar, etc. window frame. The reflector leaned out the window frame at different angles to catch the sun and shine massive amounts of light into a room. A great item to watch for at your local salvage shop.

This reflector is shown below:
