.i Be it known that I, BENJAMIN R. EAMES, of*y South Newrypin the county of Oxford andjState `of1 `Maine,` have `invented a new and useful.Improvement Door-Fastenf ers; and Ildohereby declare that the fol- .Y l owing is a full,`clear, andfeXact description of the construction land operation of the same, referencebeing hadto the annexed a drawingLforming part `of this specification, l finwh'ichfg i l Figure lis a sectionof door andjamb,

Fig.` 3 is a view similar to Fig. 1- showing compensator inuse. a of fastener in position shown in Fig. 3. .i Fig. 5` is a "view showing hooked barin po` brace removedfrom door and Fig: 4L is a side view sition, and

The "inventionhere `considered belongs to the-class of detachable `door fasteners, ,made

up `as general features of a part connecting the*` fastener to the frame, with guiding,

bracing and compensating arrangements.

"A," great defect in `most of these fasteners arises from so connecting the bracewith the C body ofthe fastener as to give it a vertical movement;` the eect of wear in `most cases being to loosen u the vattachment and `render the brace liable to `fall` of itself.

The designfof thisinvention isto'obviate all` tendency to loosening in the brace, 4and render the same `capable of performing the double functions `of brace and gage, besides other advantages which will be fully set The nature `of the invention consists in constructing the main` body, `or attaching `part of the fastener, of` a bifurcatedhooked a bar, having a triangular brace swung on the rear portion of the bar between the jaws of a spring compensator, also'movable on `said, `bar so that by reason jof the horizontal movementofthe brace, it will act as `both "brace and gage while its compression between the jaws of the" compensator will render its motion at `all times suficiently stiff to prevent self action fromloosening.

In the drawing B "isthe body `of the fas- `tener consisting ofthe two hooked legs b connected by the part a. Onthis connecting a portion a, are swung the brace G andcomlips Z` into the jamb I in the manner usual with such fasteners; the brace G being in theposition shown by red lines in Fig. 5 durmgthe closing of the door D, and thus acting as a certain gage for the position of the att-aching bar. When the door is closed,

and the lips Z driven home, the brace G is thenmoved into the position shown in Fig. "l, and the door is securely fastened. The

grasping of this brace by the compensator C effectually` prevents its movement about a without the application of force on one side; and as the compensator is a spring no amount of wear can change this stiffness in the movement of the brace. When the space between the door and jamb is wide, the compensator has the position shown in Figs. 3 and 4, while the action of the combined gage and brace G is the same.

By this construction of fastener a compact, effective and economical article is produced, and altogether free from the ,disadvantages ofthose now in use.

. I expressly disclaim hooked` bars with separate and vertically moving` stops and braces, as such -form no part of my invene tion. a But I do claim as new and of my own inven tionl The herein described combination of bifur-` cated hooked bar B, spring compensator C, and horizontally moving brace G, the compensator and brace movable about the vertical connection of said bar; whereby the self movement of the brace is prevented, while it performs the double function of gage and brace. f

In testimony whereof, I have hereunto signed my name before two subscribing wit- IIESSGS.

BENJ. E. EAMES.
