JOHN 0. SMITH, or NORWICH, CONNECTICUT.

SLAT-ADJUSTER.

Specification of Letters Patent.

Patented May '7, 1907.

Application filed July 12,1906. Serial No. 825,885.

To all whom it may concern:

Be it known that I, J OHN 0. SMITH, a citizen of the United States, residing at N orwich, in the county of New London, State of Connecticut, have invented certain new and useful Improvements in Slat-Adjusters and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. a

This invention relates to shutters and more particularly to slat adjusters therefor, and has for its object to provide a slat adjuster which will be simple and Cheap, which will be so constructed that it will be unlikely to become broken or deranged, and which may be operated to move the slats of the shutter and to hold them at different points of their movement.

Other objects and advantages will be apparent from the following description, and it is to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views, Figure 1 is an elevational view, showing a portion of a shutter provided with the present invention. Fig. 2 is a longitudinal section of the adjuster, taken on line 22 of Fig. 1. Fig. 3 is a bottom plan view of the block.

. Referring now to the drawings, there is shown a shutter including side uprights 5, having horizontal slats 6 pivoted therebetween, and a lower connecting member 7. A vertical shift rod 8 is pivoted to the several slats 6 and has a U-shaped plate 8 engaged therewith at its lower end, the plate lying against the forward and side faces of the shift rod.

A yoke 9 has its arms located at opposite sides of the shift rod, with their extremities against the spaced portions of the plate 8, and with its bight beneath the lower end of the shift rod, and fastening devices 10 are eninto the shift rod, to pivotally connect the yoke with the shift rod for movement toward and away from the shaft.

The bight of the yoke 9 carries a downwardly extending stem 11 provided with notches 12 in its forward face, and secured to the connecting member 7 of the shutter, there is a block 13 which extends forwardly therefrom in the form of a nose 1.4, and this block has a slot formed longitudinally in its nose and extending vertically, the slot opening through the rearward face of the block and being thus closed at its rearward end by the connecting member 7. The block may thus be readily engaged over the stem 1 1, as will be readily understood, and the forward portion of the nose is reduced in thickness vertically to enter the several notches 12 interchangeably. As shown, the slot of the block is enlarged laterally within the nose, as shown at 15, to receive a helical spring 16, the slot itself being indicated at 15, and the spring thus bears at one end against the stem 11, and at its other end against the member 7, to hold the stem yieldably a ainst movement to disengage its notches rom the forward portion of the nose. At its lower end, the stem 11 is provided with a finger piece 16 which may be pressed to move the stem against the action of the spring, when the stem may be operated to shift the slats 6, as will be readily understood.

What is claimed is:

The combination, with a shutter including a frame and horizontal slats pivoted thereto, of a shift rod pivoted vertically to said slats; a U-shaped plate secured to the forward face of the lower end of said rod, said plate having its arms extending across the opposite side faces of said rod; a yoke having its opposite arms pivotally secured to the corresponding plate arms, the bight portion of said yoke carrying a depending stem provided with notches formed on its forward face; a forwardly projecting block secured to the lower member of the shutter frame and provided with a longitudinal slot through which said yoke end is adapted to pass, said slot having a gaged through the arms and the plate 8 and 1 closed forward end and being enlarged later ally; a spring disposed Within the enlarged slot, topermit the verticaladjustrnent of said portion of said slot and adapted to bear shift-rod. 10 against said notched stem to hold the latter In testimony whereof, I a'ffix mysignature, normally in engagement with the closed end in presence of two witnesses.
