Description
' and useful Improvement in Door-Knobs and thereon UNITED STATES PATENT OFFICE.
JOHN EVANS, OF NEW HAVEN, CONNECTICUT.
IlVlPROVEMENT IN ATTACHING DOOR-KNOBS T0 THEIR SPINDLES.
Specification forming part of Letters Patent No. 103,590, dated May 31, 1870.
To all whom 'it may concern:
Be it known that I, JOHN EVANS, of New Haven, in the county of New Haven and State of Connecticut, have invented a certain new the Mode of Securing the Same to the Latch- Shaft; and the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents a -sectional view of a door-knob, metal socket, set-screw, and latchshaft. Fig. 2 shows an end view of the latchshaft, socket, screw, and knob.v Fig. 3 is an enlarged view of the end of the metal socket, showing the form of the opening to receive the latch-shaft.
The object of my invention is to adjust more accurately the knobs to the various thicknesses of doors, and to secure them in their proper position more firmly in the easiest manner.
My invention consists simply in the form or slightly-tapering sides of the socket in which the latch-shaft is fitted, so that when the slightly wedge-shaped shaft is pressed into the socket by a screw or its equivalent it is held at any point in the firmest manner, and can be instantly relieved, so as to allow the knob to be taken oit.
To enable others to make and use my improvement, I will describe it more fully, referrin g to the drawings and the letters marked The latch-shaft A is made, in the usual manner, of a square bar of iron, the ends of which are made slightly narrower on one side as far as they are ever required to go into the socket B, on which a wood, porcelain, or any other suitable substance formed into the knob C may be secured. The opening b in the socket B is latch-shaft. The opening b in the socket is wider on the two parallel sides, so that the bar A will not come to 'bear against it when pressed in tight by the set-screw a, fitted in the opposite side of the socket B.
The whole device, being the most simple and.
easy to make, and can be instantly put on and adjusted to the thickness of any door, requiring no washer or anything to prevent it being too loose, can be instantly tightened up should any of the liXtures become worn, and it is accredited to be the mostsimple, cheap, efficient, and durable mode of t'asteningthat can be devised for the purpose.
What I cla-im as my invention, and desire to secure by Letters Patent, is
Securing a door-knob to the latch-bar A by means ot the wedge-shaped opening b in the socket B, the spindle being so shaped as to conform to the opening when set, and held by the screw a or its equivalent, substantially in the manner as herein described.
JOHN EVANS.
