Abstract
A device for removing putty from a window frame in the form of an L-shaped blade and a support to which the blade is adjustably attached, the support being provided with a handle and guide by means of which the blade can be moved along the window frame adjacent the groove within which the putty is located to remove the putty from the groove.

Patent number: 4802280
Filing date: February 11, 1988
Issue date: February 7, 1989
Inventor: John LaPiana


1. A tool for removing putty from the recess around a window frame within which the edge of the glass is mounted, comprising an elongate, U-shaped handle embodying a handle grip portion and longitudinally-spaced attaching legs disposed at right angles to the handle, an elongate guide of L-shaped cross section defining an attaching flange for attachment to the legs and a guide flange for engagement with the window frame adjacent the glass-receiving opening, bolts attaching the attaching flange to the legs at one side of the legs in a position such that the guide flange extends at right angles to the legs in a direction away from the legs and a detachable, adjustably-mounted, L-shaped cutting blade mounted to the attaching flange at the side thereof opposite the guide flange, said L-shaped cutting blade embodying right-angularly disposed legs comprising a first leg and a second leg, transversely-spaced, parallel cutting edges at the opposite edges of the legs, means comprising second bolts detachably mounting the first leg of the cutting blade to the attaching flange in a position such that the second leg extends downwardly from the guide flange and in a direction away from the attaching flange at right angles thereto and wherein said first leg contains spaced, parallel, elongate slots perpendicular to the second leg for receiving the attaching bolts and wherein said second flange contains threaded openings for receiving the second bolts by means of which the L-shaped cutting blade is attached to the attaching flange for adjustment relative to the guide flange.

(keep in mind that a current patent gives the right to make money from an idea to the patent holder and prevents others from doing the same; typically design patents expire 14 years from date of issue)

Well, it does look like he had a lawyer prepare his patent, which is a good idea.

My guess is that he is a fairly successful carpenter or contractor. (successful enough to afford a patent application.) In the late 1980s he was in Somerville, MA. He might have some other good ideas about working on windows. If anyone wants to track him down and get his story I will pass along more information.
