IMPROVEMENT IN LATCHES.
The Schedule referred to in these Letters Patent and making part of the same.
To all whom it may concern:
Be it known that I, ADDISOX A. S'rUAkT, of Planfield, in thc county of Bremer and State of Iowa, have invented a new and improved Latch; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being hadto the accompanying drawing forming a part of this specification. v
My invention relates to latches; and consists in a peculiar arrangement of parts which will tix-st be described in connection with all that is necessary to a full understanding thereof', and then clearly specified in the summary or claim.
In Figure 1 of drawing- A represents the door;
l5, a lock-case; and
C, the sliding-bolt.
a. is thc actuating spring, which shoots the bolt.
d is a friction-roller; and
1 D are two inclined pieces or wedges, which slide in the slot b, and pass each other.
e is a thumb-piece, working through a. socket i handle on each side of the door.
E, in Figure 3,'is the form of handle which I pn ferably employ; and
F, in Figure 2, the night-latch.
The object of my invention is to afford a convenier and handy device-for latching and unlatching the doc from either side.
Having thus described all that is necessary to clear understanding of my invention,
That I claim as new, and desire to protect by Let ters Patent, is-
The arrangement, in the slot b, of the two incline or wedge -pieces D D', as set forth, so that one wi pass by the other when pressureis exerted on thumb-piece, O, from either side of the door.
