Celebrity Invention: Bing Crosby's Window Sash Holder
By Rebecca Greenfield

Some celebrities aren't just pretty faces. A few of them are also touched with that Yankee prowess for tinkering and invention. In this weekly series, we introduce you to the Patents of the Rich and Famous. And maybe you learn a little bit about how patent literature works along the way.

Inventor: Harry Lillis Crosby a.k.a Bing Crosby

Known For: With his distinct baritone, Bing made his mark as a crooner back when that kind of music was popular. He represents a more wholesome time in American history -- before rock 'n' roll corrupted our youth with talk of sex and drugs.

Invented Apparatus: "Window sash holder"

It's a holder for the string that opens and closes window blinds.

A holder adapted to develop a frictional resistance between a sash and a window frame sufficient to hold the sash in a selected position, but insufficient to prevent the sash from being raised or lowered.

Rationale Behind Invention: We've all struggled with blinds. Those two strings that have the weighted balls at the end don't make sense -- they're testy and always seem to break. Having wrestled with his fair share of window treatments, Bing invented a holder for the sash. The device is designed to stymie any wear and tear on the mechanism and still allow the shades to be drawn:

Most conventional sash windows, and particularly those made of wood, are held in position by counterbalancing mechanisms, such as sash weights housed in the windows, and particularly those made of wood, are held in position by counterbalancing mechanisms, such as sash weights housed in the window frame stricter and connected to the window by sash cords, or preloaded springs housed in the window frame structure and connected to the window by wire cables. Such holders often become inoperative after a long period of use because of failure of the sash of cords or sash cables. The lower sash then will no longer remain open and the upper sash will not stay closed.

Off-Label Uses: Users would probably tie other unruly strings to the holder -- like the one attached to the ceiling fan -- just because, well, who could resist?

Future Directions: During the summer months, figuring out just the right balance between windows open and shades drawn is key to keeping your home cool. You want a nice breeze, but the sun can really heat up a room. Bing should install a temperature control that tells the user the right window/blind combination for optimal comfort.



  1. Ha! Who knew...Bing was such a talented guy though so I shouldn't be surprised that he was also an inventor.
    What a fun and informative post.
