In pursuit of Prindle…

Not that I am obsessed with door-securers…

…but, on August 13, 1907 George Prindle was awarded patent number 863,091 for his Combined Door Securer and Corkscrew.

Within his patent description, Prindle explains:

The tool embodying the invention comprises two flat plate-like members, one of which is shorter than the other, being about one-half the length thereof, and said members being pivotally connected together at one end so that when the members are folded to occupy parallel planes in contact with each other throughout their lengths the free end of the shorter member occupies a position about the center of the length of the longer member, and at the free end of the shorter member is located a cork screw stem or shank, pivotally mounted so as to be folded into position parallel with shorter member and adapted when extended to occupy a position perpendicular to the planes of the two members of the tool and at about the center of the length of the longer member, so that the folded longer and shorter members constitute a handle extending about equally upon the opposite sides of the line of the extended corkscrew stem or shank to form a suitable grip.

He later goes on to explain how the door securer part of tool works, but as importantly, takes the time to point out that with the door securer in place, securing the door, the corkscrew can be extended for use—in this manner like a wall-mount.

Prindle explains, It will be observed, moreover, that when the tool is in use as a door securer, the cork screw is exposed, so that it may be used by presenting the bottom and turning the latter to cause the cork screw to engage the cork, as indicated in the dotted lines in Fig.3, the tool being thus held rigid and stationary by its engagement with the door and frame.

Of course, in thinking about installing the door securer, and then twisting a bottle onto the helix, and then pulling with the force necessary to get the cork to release…how many of these would have survived that amount of force.

And, how many people, upon the release of the cork from the bottle, would have ended up across the room.

To my knowledge, an example of the Prindle has yet to be found, and while the hunt for the Prindle is ongoing, if any of you out there do have this, I would love to acquire it.

Matthews’ 1893 patent arrives…

Yesterday, the Matthews patent door securer with corkscrew arrived, and it didn’t disappoint.

Nicely marked, it is in fabulous condition with a sharp helix, and it is an awesome addition to the collection.









Note: the door securer is threaded, and screws into the center piece.


As mentioned previously, it is marked for Matthews’ 1892 patent, as his 1893 patent is a combination of his 1892 patent with the addition of the case and corkscrew in 1893.


And, the corkscrew does function as a peg and worm, with the door securer serving as the peg.


I haven’t tried this out yet…as a corkscrew NOR as a door securer…
