IMPROVEMENT IN COMBINED SHUTTER-WORKERS AND BLIND-OPERATORS.

Specification forming part of Letters Patent No. 143,289, dated September 30, 1873 application filed August 4, 1873.

To all whom it may concern:

Be it known that I, DANIEL M. LEONARD, of La Orosse, in the county of La Grosse and State of Wisconsin, have invented a new and. Improved Shutter-Operator, of which the fol lowing is a specification:

In the accompanying drawing, Figure 1 represents a side view of my improved shutteroperator, partly in section, on the line 0 c, Fig. 2; Fig. 2, a horizontal section of the same on the line w m, Fig. l and Fig. 3, a detail bottom view of the gear-wheel and stops, partly in section, on line 3 3 Fig. 1.

Similar letters of reference indicate correspondin g parts.

The object of my invention is to provide a simple and convenient mechanism for operating, adjusting, and lockin g the windowshutters and blind-slats from the inside of the Window.

In my invention a cog-wheel is keyed on a sliding shaft to be brought into engagement, alternately, with a toothed disk attached to the shutter, and toothed segmental lever connected with the blind-slats, whereby both the shutter and slats may be adjusted as desired.

In the drawing, A represents the Windowframe B, the shutter or blind, and O the crank-shaft, which is operated by handle D inside of the window, being arranged, preferably, near the window-sill. The crank-shaft 0 passes through a recess of frame A, held by inner and outer metallic guide-facings a, and is provided with a spiral spring, I), which acts on a shoulder, 11, of shaft O, and forces the same in an outward direction. A cog-wheel,

E, is keyed to the end of shaft 0, and meshes into a notched or toothed disk, F, which is firmly applied to shutter B, and turns on its central pin 6 in recess or socket e of the sill. By drawing crank-shaft O toward the inside, spring b is compressed and cog-wheel E placed out of gear with disk F, the side of frame A being sufficiently recessed at f for this purpose. The wheel E engages then in this position, on turning the crank-shaft O, the forward-projecting toothed segment g at the end of lever G, which is pivoted to the shutter B, connecting with its opposite end to the blindslat rod h by hook h, and setting thereby the slats into any position desired. On releasing the crank-shaft C, it engages disk F again, and opens or closes the shutter as the crank is turned. Two or more recesses, i, are applied atthe bottom of disk F, which are engaged by spring-bolt H locking the shutter into closedor open position. The bolt H is placed parallel to and below crank-shaft 0, and provided with a knob at the inside, by which bolt H is Withdrawn and the shutter operated in either direction by crank O.

Having-thus described my invention, I

claim as new and desire to secure by Letters Patent The combination of crankshaft O and cogwheel E, arranged in frame A, with toothed disk F, pivoted lever G, shutter B, and springbolt H, for operating, adjusting, and locking both the shutter and blind-slats, substantially as described.

DANIEL M. LEONARD.
