Ellison tilting window spring balance shoe and spring.

Hello,

I need a pair of shoes with springs or possibly just a replacement spring.

The combined nylon shoe and spring housing measures 2 7/8" long by 1 3/16" wide by 9/16" thick.

Spring is marked "21V" (possibly preceded by the numeral 7 which is in a larger font.)

The lower shoe can be easily separated from the spring housing by sliding the shoe out on two key ways molded into the upper spring housing.

The AAMA sticker identifies this as an Ellison window ( mfr code ELl-1)

The balance supports a sash that measures 29"x22.5" and weighs 12.5 pounds.)

I can't seem to find an obvious match among the shoes you offer so hopefully you can make a suggestion. Thank you.

Thanks for the quick reply.

With a proper set of calipers the original shoe measures 1 1/4" wide and 9/16" thick.

I could not remove the pivot bar but I think the attached pictures will do. Its cross section is 3/16"x 5/16" and it protrudes about 5/8" from the sash.

The spring does indeed fasten to the rail with a bracket like the one you showed. The bracket screws in with a single screw 26" above the bottom of the sash when it is closed

It was the two holes needed to mount the spring that allowed me to identify the 180 series balance so I ordered 2- 7 lb springs.

I also ordered an S-161 Roller tilt as it seemed it would fit. ( Your opinion?)

If I have to rely on using the 180 coil balances for the repair, is it correct that I do not have to attach the inner end of the coil, it just sits rolled up in the spring casing ? In the original there is a small cylinder that "floats" in the space of the inner coil. I'm thinking its purpose is to prevent the inner end of the coil from leaving the spring housing ( somehow) if the balance is extended to its max.


Thank you.
