UNITED STATES PATENT EEICE.
JOHN L. ZESIGER, OF CLEVELAND, OHIO.
CHECK FORy DOORS OR BLINDS.
SPECIFICATION forming part of Letters Patent No. 582,449, dated May 11, v1897. Application iiled April 20, 1896. Serial No. 588,325. (No model.)
To all whom it may con/cern.-
Be it known that I, JOHN L. ZEsIGER, of Cleveland, Cuyahoga county, Ohio, have invented certain new and useful Improvements in Checks for Doors or Blinds; 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 pertains to make and use the same.
My invention relates to an improved check for doors and blinds.
The object is to provide a simple, durable, and cheap device of the character indicated; and with this object in view the invention consists in certain features of construction and combinations of parts, hereinafter described, and pointed out in the claim.
In the accompanying drawings, Figure 1 is a view in perspective of the lower portion of a hinged door, blind, or shutter and the adjacent portion of 'a wall of a room or building against which the door, blind, or shutter is moved in opening, and shows my improved combined check upon the wall, and shows also the keeper-plate that is secured to the door or blind and cooperates with the catch of the check. Fig. 2 is a top plan in horizontal section, showing the door or blind held open by my improved combined check.
Referring to the drawings, A represents a door, blind, or shutter hinged at a to an upright support in any suitable manner and adapted to open against the wall B of a room or building. The door, blind, or shutter is provided in the edge thereof with a mortise A', and a keeper-plate C is secured to the doors edge over said mortise and has a hole or slot C therethrough that registers with the aforesaid mortise.
D designates myimproved combined check, that consists, preferably, of two parallel plates d d', arranged a suitable distance apart vertically and secured together in any approved manner at or near their inner ends, and preferably by a rivet or pin d2. Plates d d at, their inner ends are provided with external iianges d5, that in Fig. l are shown secured to the wall by screws E. Plate d at its inner end is enlarged inwardly, as at d4, (see Fig. 2,) and said enlargement d4 acts to Enlargement d near the outer longitudinal edge of plate d is provided with an undercut recess (Z5, whose undercut wall d is engaged by the inner end of a leaf-spring G, that at said end is bent laterally and inwardly against said wall c. Spring G extends between and to the outer ends and longitudinally of plates d d and at its outer end is adapted to engage either one of two shoulders H H2, with which a catch H, that is pivoted centrally at 7L to and between the outer ends of plates d d', is provided. Shoulder H' or shoulder H2 will be engaged by the spring, according las the catch is in its operative or inoperative position. Shoulders H and H2 are arranged at right angles to -each other or approximately so. Catch H at a point diametrically opposite the vertex of the angle formed by shoulders H H2 is provided with a V-shaped notch H5, having its side walls H4 and H5 preferably parallel with shoulders H2 and H', respectively, or approximately so.
The arrangement of parts is such that when the device has been applied side wall H4 of notch H3 shall be arranged in the line of the are through which the keeper-plate on the door moves during the opening of the door or blind into engagement with the stop, and hence said wall Hl in the operative position of catch H is in position to be engaged by the edge of the keeper-plate, and the door or blind when it is moved against the stop strikes saidv wall of the notch in the catch and thereby actuates the catchs tongue-constituting member H5, formed between wall H5 of the notch and shoulder H2, into the mortise in the edge of the door or blind through the hole in the keeper-plate, andv thereby holds the blind or door in its open position and sufciently positive to prevent a draft of wind from being effective in closing the same.
The two plates d d' are cut away at their outer ends in the line of the path of the door or blind, so as to form a stop-constituting shoulder or shoulders C17, adjacent to the inner extremity of the catch, for arresting any further movement of the door or blind in the direction of the wall after the actuation of the catch into its operative position,and the catch, at the inner end of shoulder H2 next to tongue H5, is provided with a narrow shoulder 71.', arranged at right angles to shoulder H' and adapted to engage the outer extremity of the IOO spring upon the actuation of the catch from its operative into an inoperative position, and thereby prevent the catch during its said movement from being thrown beyond its inoperative position. A Plate CZ, at the outer side of the spring and adjacent to the undercut recess, is provided with a rib or flange d8, that not only forms an outer bearing and prevents outward displacement of the spring, but reliably retains the spring in engagement With the catch.
A combined check for a door, blind, dac., having its body portion cut away at its outer end to form the shoulder or shoulders C17; the catch Il pivoted centrally to the body portion between said shoulder or shoulders and the body portions outer extremity, said catch H having two shoulders H and H2 arranged at right angles to each other, or approximately so, atone side of its axis, and provided, at the opposite side of its axis, with a laring notch or recess 113 whose one side wall H4 is arranged to be engaged by the door or blind preparatory `to the latters actuation of the catch into an operative position, and the catch having a tongue Il formed between the opposite side wall of said recess and the aforesaid shoulder H'; a spring G engaging shoulder H, or shoulder H2, according as the catch is in its operative or inoperative position, and a keeper-plate O, substantially as shown, for the purpose specified.
In testimony whereof I sign this specification, in the presence of two witnesses, this 17th day of April, 1896.
JOHN L. ZESGER.
