To ALL WHOM 1T MAIY CONGERN.; s Y
Be it known that we, FRANKLIN BABoooK and FRRDERICK Bincocx, of Middletown, county of Middlesex, :ind State of Connecticut, have invented a new .and improved Door-Latch; -and yve do hereby declare that vthe 'foilowin'gis a full and exact` der xer'iption of the some,V reference 'being had to the accompanying drawings.l

Figure 2 is a. sectional view, and Figure 3 :in end view of the-door -latchg and Figure fi is a, perspective view, Figure' is a'sectionallview, and
Figure- Gan end viewof ythe 'bolt-reoeiver. yTo enable others to understand the .use' and consti-notion of our invention, we will proceed to describe it. We'mak a cylindrical shell' or' cosefgs. 1, 2, and 3, with projections or arms d d, iig. 1, extehding a. propendietance from the s ih'ell, to provide a bearing i'orthe oa`m a, thp can; to be operated by means of a knobspindle. T le bolt b is connected to the am a by a chain or links, e e, so thatibyturning the knob, thebolt b is drawn from the receive figs'. 4, 5, .and 6, and.y is thrown beek by'the'springc.
on its outer periphery to secnre'it firmly in its place without the use of The Shen has a sorts-threes detached screws. It also'possesses the' advantage of 'being applied with gteater'faoility than ordinary doorV latches, requiring simply theboring of a 'hola of proper dimensions, without removing the wood about the spindle,
which o i'ton prevents the proper securing of the knob-plates for wantpf suioient thickness of wood to hold -the serews.V v f l The receiver, 'iigs. 4,; and 6, is made inthe same manner'. as the shell of the l'ntch, havingl a screw-thread on its youter periphery, td secnreit iirmlygin its-place, and the receiver-plate f being secured to lthe case by the dangling. theshell. I Y g l v v Y `o Inovelty of our invention is its, easyapplication,.dui-ability, and compactness. I
We are aware that a latch;V wit goil-spring around, and .opernted by chains, connecting with a revolving socket, is not new. The; cam a'used by ns is-provided with a. circumferential Bange in its centre, and is .secured in the ooneztveencls'ot'v the oase, thereby dispensing nv vith -journale or axes.
