The accompanying engraving represents, in perspective and in section,
an improved door bolt, recently patented by Mr. Thomas Hoesly, of New
Glaras, Wis.
The principal features of this bolt will be understood by reference to
the engraving. On the plate or body are cast two loops or guides for
the bolt, and the plate is slotted under the bolt, and a lug projects
into the slot and bears against a spring contained by a small casing
riveted to the back of the plate. The end of the bolt is beveled, and
its operation is similar to that of the ordinary door latch. Two
handles are provided, one of which is of sufficient length to reach
through the door, and a pawl or dog accompanies the bolt, which may be
attached to the door with a single screw, and is to be used in locking
the door. The bolt is very simple and strong, suitable for shops,
out-buildings such as barns, stables, etc., and some of the doors of
dwellings.
