IlYlPBfO-ED SHUTTEB. FASTENING.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, .WILLIAM B. HOWARD, of Baltimore, in the county of Baltimore, and State of Maryland, have invented a new andjinproved Shutter Fastening; and I do hereby declare the following to be a. full, clear, and exact description of the same, suicient to enable one skilled in the art Ato which the invention appertains to make use of it, reference being had to the accompanying drawings, which forms a part of this speciiication, and in which- Figure 1 is a front elevation of the shutters closed.

Figure 2 is an enlarged view of a single fastening in elevation.

Figure 3 is a side view of a single fastening in its lockedlposition.

Figure 4 is a. top view of' a. single fastening in the act of closing.

Figure 5 is a. Bide elevation of a. single fastening in the act of. closing.

A tumbler is pivoted to a. bracket, which is attached to the jamb or the shutter. By the opening of the shutter it is raised, and when the shutter is fully open it falls between two cheeks on the bracket attached to the other object.

In the drawings, A A are the jambe of the window casing, B B the shutters. In the case of the shutter B the fastening is attached midway. between the-hinges H H, and in the case of the shutter B the fasteniugs are placed in the vicinity of the hinges. The fastening consists of two portions, which are attached, respectively; to the jamb 'or to the shutter. One portion has two cheeks, G F, on a bracket, E, and the other portion has a. pivoted tumbler, D, on a bracket, C. The brackets are constructed especially for right and left-hand shutters; but the tumbler bracket may be on the shutter o1' jamb, the other bra-akelneing :attached to the other object. l

The operation is as follows: The shutter being opened, the lower edge of the pivotetnznbler strikes Athe .inclined plane F on one of the cheeks of the bracket E, and is thereby raised; the shutter Acontinues to open until it strikes back against the walk-when the tumbler D falls down between the G F, end .is then locked, fastening the shutter open. To close the shutter, the tumbler is raised, which frees it from the fastening.

Having described my inventicn. what I claim as new, and desire to secure by Letters Patent, s The arrangement of the tumbler-bracket C D and the check-bracket F G E, constructed and operating substantially as described and represented.

WM. B. HOWARD.

W'itnesses:
