Lampshade Underpinnings

Harps (not the musical kind), spiders (not the scary kind), and other things you might find under a lampshade.

Harps
Harps
Sometimes when you have nothing else to do, you should examine some of the lamps in your house. If you peek under a shade, you may notice a certain frame-like device which is connected to the lamp, and which supports the lampshade. This device is called a harp, and is particularly useful if you happen to need one. Taking it for granted that there are a certain number of people that need almost everything, we have ordered in a goodly supply of these, trusting that we will be able to sell them to customers who are making stained glass lampshades to fit lamps that do not have harps. All of these harps have a threaded stub at the top, which is cut to fit a 1/4-27 fitting. You will notice that all of the finials which we stock are threaded 1/8 I.P. Thus, in order to use a finial at the top of a lampshade which is being supported by the harps we sell, you would have to purchase #6627 Reducing Bushing. These are available at modest cost..

For the small 7" and 8" high lamp shades. The clip fits onto any standard light bulb. The stud at the top is threaded 1/4 - 27, the same as the stud at the top of the harps. If you buy one of our #6627 Reducing Bushings, you can adapt this stud to thread into our #6600 Crossbar, any of our finials, or any other thing which is tapped 1/8 I.P.
Spiders
Spiders
These brass-plated lampshade holders are mentioned many times in patterns and instruction books concerning small lampshades. They can be cut to smaller sizes to fit specific situations. The heavy center washers have a 7/16" hole, which slips over standard threaded nipples. Mr. Orris Root, of Punxatawney, Vermont says: "When we had our annual Sunday School picnic last November, we brought along your spiders, and long pointed sticks, which we jammed through the washers. They were perfect for roasting our wienies over the campfire. We call them our Whittemore-Durgin Multi-Wienie Roasters."
