SCREEN-DOOR-OPENING DEVICE.

SPECIFICATION forming part of Iletters Patent No. 560,478, dated May 19, 1896.

Application filed January 25, 1896. serial No. 576,861. (No model.) i

To all whom it may concern.-

Be it known that I, GEORGE WILEY Cou- GILL, a citizen of the United States, residing at I-Iumphreys, in the county of Sullivan, State of Missouri, have invented certain new and useful Improvements in Screen-Door- Opening Devices; and Idohereby 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.

My invention relates to improvements in door-opening devices, and is especially applicable for use on screen-doors and the like.

The invention will first be described in'connection with the accompanying drawings, and then particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a screen-door provided with my improvement. the door. Fig. 3 is an enlarged detail view of the bracket-arms and lever.

Referring to the drawings, A is a screendoor hinged to the door-casing B by hinges a and normally held closed by a spring C, secured at one end to the inside of the door and at the other end to the casing.

To the side of the casing nearest the hinges a of the door is attached a bracket-arm D,

formed of one casting and having a back d, which is approximately triangular and extends above and below the bracket-arm D, having two slots (1 in its upper portion and one slot d in its lower portion, the back being secured to the door-casing by screws passing through these slots, the said slots permitting a limited amount of adjustment of the bracket on the casing. The bracket-arm is provided with two integral braces d connectin git to the back cl in order to stiffen said arm. At the front end of the arm is a table or plate at", which slopes forward and downward at a slight incline and is provided at its center with an integral stud 01 having a central bore or opening which is threaded. At the upper end of the hollow stud and on each side of the bore or opening are two notches, as shown at d. 'On top of the said table or plate (1 is located a lever E, one end of which is longer than the other, the said lever having a hole through which passes the stud (1 which serves as a fulcrum for said lever.

Fig. 2 is a cross-section through To hold the lever E from coming off its f ulcrum, a cap 6 is provided, this cap having two lugs e on its under side which enter the notch d in the hollow stud, and thus prevent the cap from rotating. To hold the cap 6 in place on the stud, a bolt or thumb-screw e is passed through the'cap and threaded into the bore or opening in the stud.

To the longer end of the lever E is attached one end of a cord or chain F, whose other end is secured to the outside of the screen-door in any suitable manner. The other or shorter end of the lever E is connected to one end of a draft-cord G, which passes around a pulley H, secured to the upper corner of the doorframe and thence down to a treadle or foot piece I, hinged to the door-frame by a hinge 'i, the said treadle normally projecting about at right angles to the door-casing when the door is held closed by its spring and being arranged to swing down when pressed by the foot, thereby drawing on the draft-cord G and causing the lever E to swing, so as to open the door. In this manner the door may be readily opened by the foot by any person, which is convenient when the hands are otherwise employed, as when carrying parcels into and out of the house. The length of the two arms of the lever E are so proportioned that the downward movement of the treadle I from an approximately horizontal position to a somewhat dependent position will cause the full opening of the door.

By sloping the table or plate 61 downward and forward, as previously mentioned, the front end of the lever E is kept approximately on a line with the point of attachment of the cord or chain F to the door, so that said front end of the lever E pulls the door open without too much of an angular strain, and at the same time the bracket-arm D is kept out of the way of the door.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a door-opener, the combination, with a bracket-arm secured to the casing above the door and on the side nearest the hinges, of a lever pivoted on said arm, and having a long and a short arm, a cord connecting the end of the long arm to the door, a draft-cord connected to the short end of the lever, a pulley at the upper corner of the casing, around which pulley the draft-cord passes, a treadle at the lower end of the casing and hinged to the same, the draft-cord being secured to the said treadle and a spring for closing the door, substantially as described.

2. In a door-opener, the combination, with abracket-arm secured to the casing above the door and on the side nearest the hinges said bracket-arm having a plate on its outer end provided with a stud projecting upward, of a lever pivoted on said stud and having along and a short arm, a cord connecting the end of the long arm to the door, a draft-cord connected to the short end of the lever, a pulley at the upper corner of the casin g around which pulley the draft-cord passes, a treadle at the lower end of the casing and hinged to the same, the draft-cord being secured to the said treadle and a spring for closing the door, substantially as described.

3. In a door-opener, the combination, with a bracket-arm secured to the casing above the door and provided with a plate at its outer end sloping downward and forward and having a stud provided with notches, of a lever pivoted on said stud and having a long and a short arm, a cap mounted on the upper end of the stud and provided with lugs entering the notches in said stud, means for holding the cap to the stud, a cord connecting the end of the long arm to the door, a draft-cord connected to the short end of the lever, a pulley at the upper corner of the casing, around which pulley the draft-cord passes, a treadle at the lower end of the casing and hinged to the same, the draft-cord being secured to the said treadle and a spring for closing the door, substantially as described.

In testimony whereof I affix in y signature in presence of two witnesses.

GEORGE WILEY COUGILL.
