Letters Patent No. 95,231, dated September 28, 1869.


The Schedule referred to in these Letters Patent and. part of the same.

Togall whom it may cou'ccra: Be it known .that I, HENRY M. JONES, Vof West Meriden, in the county of New Haven, and State of Connecticut, have invented a new 'Improvement in Door-Fastener; and I1 do` hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, 'and which said drawings constitute part of thisspecitication, and represent in Figure 1, a perspective view of the f'astener, and in Figures 2 and 3, views to illustrate the operation; lhis invention relates to an improvement in porta- `ble iastenings'for doors, designedfor the occupants of rooms, to insure the fastening upon the inside without depending solely upon the lock on the dooryand The invention consists in a key formed from sheet-4 metal, consisting oftwo legs, the inner or corresponding edges of which are inclined to each other, so that the said key may be passed between the door and jamb, one leg passing above and the other -below the latchbolt, and so `that when pressed hardon to the latch,

i theedges of the two legs will so iirmlygrasp the latclrbolt as to prevent itsbeing 4moved by means of the knob upon Vthe opposite side.`

myinvention, I will fully describe 4the saine, as illustrated in the accompany-in g drawings.

From suitable sheet-metal, preferring steel, I out the key, as seen iuig. 1, with two legs, A and B, their inner edges inclined to each other,so as to be broader at the open endthan at thelbase.

` lhe handle or base C may be of any desired form.

By preference I forni the `inner edge of' each leg vto lo lenable others skilled in the art to make and use` `and press the .key hard on to the bolt, so as to embed the edge into the metal, or to firmly grasp the bolt, and the door is secure, as 4the bolt thus clasped cannot be operated by the knob upon the outside.

This instrument is so small as to be .no inconvew ience to the person carrying it, and can be applied to all latch-bolts, inasmuch as the key is so thin--that it can be easily pressed on to the latch-bolt however closely the door may close-two great' advantages over other door-fasteners.

Having fully described my invention,

What I claimas new and useful, and desire to secure by Letters Patent, is

As an articlefof manufacture, the hereindescrihed doorastencr, consisting of the two legs A and B, their inner edges inclined to each other, and formed upon aV single base, substantially as and for thevpurpose herein set forth.
