' Letters Patent No. 64,704, dated May 14, 1867.

IMPROVED DOOR-HOLDER.

T0 ALL WHOM IT MAY CONCERN:

Bc it known that I, WILLIAM QUAYLE, of Warsaw, in the county of Hancock, and State of Illinois, have invented a new and improved Door-Holder; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the artto make and useA the same, vreference being had to the accompanying drawings, forming part of this specification.

This invention relates to theimanner in which a swinging door is made to stand in any desired position when open, and the invention consists in an arrangement by which aired and an elastic or other roll isprcssed downward upon the iloor or carpet, and raised or controlled, as will bc. hereinafter described.

Figure 1 represents a vertical section of thc edge of the door through the line z z ofg. 2l

Figure is a side elevation of the door, partly in section through the line a: :c of tig. 1.

Figure 3 is a crossfsecltion through the line y "j, of fig. 1.

Similar letters of reference indicate like parts.

A represents the door B B -'s a.- donble crank, one portion of which, B, extends through the side of the door, by which the device isf operated and controlled; C is a vertical rod, which is connected with the inner crank B by a Wire, d, of suitable trength; D represents a spiral spring, which surrounds the rod C; is a dovetail-shaped piece of metal, attached tothe-end of the rod C, and to which thc roll lijs attached; F is the roll; G is a metallic chambered plate,in which the crank B operates; the outer or plate portion is ilush with the edge of the door to Whichit is screwed; H is another chambered .plate similar to G, the outer ppi-tion of which is flush with the door, to which it is valso screwed.' The guide-pieces a a, which support the slide E, are attached tothe inside ofthe plate H, as seen in fig. 3; b is 'a piece projecting `inward from this plate, and through which the rod C passes. The upper end of tlie spiral spring D bears against this piece from which it recoils against the slide E, pressing it and the rod down with a constant pressure. When the crank is turned up, as seen in 'the drawing, fig. 2, the rodand the roll F are raised from the door. It will be noticed that the crank is thrown a little back from its centre of motion, and when it is in this position it may be said to be locked, with the roll drawn up. I In the other position (shown i n iig. 1) the spring is pressing the roll to the iloor. The cross-section (fig. 3) shows the shape of the slide E, and the position ofthe rod C. The central pivot upon which the roll turns is seen at t'.

I do not confine myself to a revolving'roll in this connection. The roll or any elastic substance mightbe rigidly attached to the slide and the same eiect be produced, `but ii' it revolved it would be less injurious to the floor or carpet, for the door might be frequently moved without turning the crank and raising the slide.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 'Holding a door in any desired position by raising and lowering the rod C and its attachments, substantially as herein shown and described.

. WILLIAM QUAYLE.
