UNITED STATES PATENT OFFICE.
GEORGE W. HAl/VKINS, OF PAWTUCKET, RHODE ISLAND.
BLIND-STOP.
SPECIFICATION forming part of Letters Patent No. 550,391, dated November 26, 1895.
Application filed December 13, 1894. Serial No. 531 ,621. (No model.)
To all whom it may concern.-
Be it known that I, GEORGE N. HAWKINS, a citizen of the United States, residing in the city of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain Improvements in Blind-Stops, of which the following is a specification.
My said invention relates to a means for adjusting and regulating the position of shutters for blinds and for holding the same in any position or at any angle that may be desired; and it consists of a shaped piece of metal having notches in its periphery and attached to the post or frame-piece of the blind, and of a sliding bolt or pawl attached to one of the shutters and adapted to fit into the notches mentioned, said sliding bolt or pawl being operated by means of a spring and of a chain or cord fastened to the strip which moves all the shutters in the group.
The accompanying drawings of my said invention are hereby made part of this specification, similar letters of reference thereon indicating corresponding parts.
Of said drawings, Figure 1 is a front View of a shutter having said device attached thereto. Fig. 2 is a view of the side of the post or frame of the shutter with the notched metallic piece attached thereto and of a crosssection of one of the slat-spindles resting therein. Fig. 3 is an enlarged and detached view of one of the slats and to which one part of the device is attached, also showing the entire device in longitudinal section and a related section of said post. Fig. 4: shows a cross-section of the slat and of said device on the line a roof Fig. 3.
a a are the slats of the shutter, and c c the posts of the frame.
d is the strip to which all the slats grouped together in the shutter are attached by means of the looped wire, (seen at e.)
f f show the shaped piece of metal having the rim c' notched, as shown at k is.
Z shows the spindle or bearing of the slats as they rest and are movable in suitable mortises in the side of the post 0. The metallic piece f is secured to the post a by a projecting lip n and screw 0.
r is the sliding bolt, one end of which is adapted to enter and rest in the notches k, and the other end, by its attached stem 25, protruding through the coiled spring a, is connected with said strip d by means of the chain c. The parts 0" t a are inclosed in a suitable cylindrical case. (Shown at w.)
The normal position of the slats, as shown in Fig. 1,.represents the shutter closed and locked in this position by the bolt end 0" resting in the notch numbered 1. To change this position, grasp the strip (1 and turn it to one side, as shown by the dotted lines in Fig. 3, and thus draw the bolt end out from the lastmentioned slot, when the shutter may be opened to the point desired, and then the loosening of the grasp of the fingers will permit the bolt end to slide back and enter either of the other notches numbered in the drawing. The shutter will then be locked in the position sought. Like operations will be only necessary to obtain other positions of or to close the shutter and to lock the same in the desired place.
The several parts described may be made from metal or other suitable material. A cord or other equivalent may be substituted for the chain c. Any other form of spring may be used in place of the coil 10, and there may be any desired number of notches in the rim or periphery '6.
Having thus described my said invention, what I claim as new, and desire to secure by Letters Patent, is-
In combination with the slats of a shutter and the strip d to which the said slats are attached, a cylindrical case fastened to one of the said slats, a bolt 1' sliding in said casing and protruding from the outer end thereof, a spring a within the said casing acting to force the said bolt outward, a chain '0 connecting the said bolt to the said strip, and the metallic piece f which is attached to one of the upright posts of the shutter frame, and provided with a rim '5, having a series of notches 7a, which are arranged to be entered by the protruding end of the said bolt in the various positions which the shutters assume as they are more or less opened and closed substantially as set forth.
GEORGE N. HAWKINS.
