Aligned together Dave Snell, AHC July 1, 2019 at 12:53 pm - Reply If you look at the floor is looks like it was a pivot set so I would say that it is an intermediate pivot. Tim July 1, 2019 at 3:04 pm - Reply Generally was used for baby gates. Bill Cushman July 1, 2019 at 3:11 pm - Reply I would guess its a cane-bolt receiver. Greg July 1, 2019 at 4:17 pm - Reply Just a guess: The closet may have been used as an area of refuge, from a tornado. Looks like the hole in the floor aligns with the device located at strike height. Robert Chillino July 1, 2019 at 6:00 pm - Reply It’s from the surface mounted multi point latching dead bolt on their panic room or fallout shelter. Better than hiding under the desk. Richard Leibowitz July 2, 2019 at 3:48 pm - Reply The top piece is a part of a two piece pintle, the bottom piece receives a pin which on larger gates sits on a ball bearing to facilitate the ease of swing. A great way to hang a large gate. Lori July 2, 2019 at 3:52 pm - Reply I wonder why it would be on the inside of a closet? – Lori Fred Collier July 2, 2019 at 7:30 pm - Reply Was there a loop screwed to the door too? If so then a hiding place or secure area for tornado / really bad storms in MN.?? Justin Robertson July 5, 2019 at 2:07 pm - Reply People are mentioning pivots, but that is clearly the strike jamb in view. Though one could make the case that this was likely retrofitted, the positioning also does not seem desirable for even an offset pivot. I would assume this is for some sort of barricade device, being on the inside of the door. It appears that this would have functioned as a safe room; from intruders, dangerous storms, or potentially to avoid an abusive situation at home (such a prevalent issue at the time it, in part, prompted the Prohibition Act in 1920). Lori July 5, 2019 at 3:17 pm - Reply That was my guess too! – Lori Jim Brown July 8, 2019 at 1:52 pm - Reply For starters, the strike plate indicates that this door had a deadbolt in the mortise lock. It was obviously not enough for the owner. It was a retrofitted with a drop bolt system of some kind that would have mounted to the door and dropped through the upper loop into the floor receptacle. Mario Toussaint July 8, 2019 at 3:53 pm - Reply In old houses, I’ve seen a lot of mortice locks with dead bolts on bedroom and bathroom doors. Even closets! Less inventory for the local hardware store. And those where activated with a bit key. The key hole went trough, thus looking trough the keyhole expression. DAVID FEDERICO August 3, 2019 at 9:54 am - Reply Looks like a bracket for the old New York Police Barricade lock unit to prevent a forced break in. metis August 28, 2019 at 9:05 am - Reply I’d love to see tool/ wear marks on the opposite side of the door frame. socket and pivot surfaces make me think something like a baby gate or ironing board or dressing dummy, Leave A Comment Cancel replyComment Save my name, email, and website in this browser for the next time I comment.
