SPECIFICATION forming part of Letters Patent No. 596, 948, dated January 4, 1898.

. Application led April 27,1897. Serial No. 634,172. (No model.)

To @ZZ whom, t frz/Cty concern:

Beit known that I, GEORGE A. SEELY, a citizen of the United States, residing at Emmetsburg, in the county of Palo Alto and State of Iowa, have invented certain new and useful Improvements in Thresholds; andIdo 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 appertains to make. and use the same.

This invention relates to improvements in thresholds or door-sills; and it consists, essentially, of a specific adjustable section and also of the details of constrction and arrangement of parts which will be more fully hereinafter described and claimed.

The object of the invention is to raise or lower the threshold at either end duringcertain seasons of the year to obvia-te the binding on the under side of a door, which arises from settling or heaving of walls, owing to changes in the weather and for other reasons.

In the accompanying drawings, Figure l is a sectional perspective view ot' a threshold or door-sill embodying the invention. Fig. 2 is a central longitudinal vertical section of the device. Fig. 3 is a detail perspective view of the adjustable attachment removed. 'Fig 4 is a detail view of a modication of the box.

Referring to the drawings, wherein similar numerals of reference indicate corresponding parts in the several views, the numeral l designates a box substantially of rectangular form and open at the top. The said box has oppositely-projecting danges 2 and 3 extending from the upper edges thereof at right angles and has the bottom thereof formed with suitable screw-seats 4 to receive the screwthreaded ends of adj Listing-screws 5, having heads rotatably mounted in and exposed through an adjustable section G, which is formed with inclines 7 extending from a central curved ridge S. Under the ridge and extending through the upper unscrew-threaded portion of the screw or bolt 5 is a pin 9, extending from opposite sidesand having the ends thereof bent down to prevent the withdrawal of the screw or bolt upwardly through the curved ridge 8, and prevents the said adjustable section from moving downwardly beyond a predetermined point. The adjustable section also has depending' langes l0, which fit into and bear against the sides of the box l, and in placing the device in position is so situated that it will center with the bottom of the door, which is to coact therewith, and if the device should conict in any way with the construction of the door-framing it can be readily positioned by slightly cutting away the resisting parts, and in operation the movable section is raised to an elevation desired to take up the space between the bottom of the door and the same, and it' the door binds at any point the movable section can be correspondingly lowered.

The material of which the two parts are to be constructed is malleable iron or analogous substance, which will resist wear; and in the bottom of the box a series of openings 1l are formed to permit water which may run into said box to freely pass away.

The device is adapted to be employed either with inside or outside doors, and in the case of ordinary doors two ad j listing-screws would probably be sufficient. However, the num- `ber of the adjusting-screws employed will be regulated in accordance with the size of the door, and the device forms a very excellent sill or threshold for double doors. At one side of the box, as shown by Fig. et, in connection with the flange 3 thereof, a dip-flange 2 is shown, which is adapted to be employed in connection with the box when the latter is used at certain points. This, however, can be readily dispensed with and will not affect the operation or the construction generally of the device as presented.

It is obviously apparent that many minor changes in the construction and arrangement of the several parts might be made or substituted for those shown and described wit-hout in the least departing from the nature or spirit of the invention.

Having thus described the invention, what is claimed as new is- 1. In a threshold or door-sill of the character set forth, the combination of a box provided with vertical sides and upper horizontal ian ges and having a movable section mounted therein, with a closed top and depending sides coacting with the vertical sides of the said box and adjusting-screws connecting said IOO movable section and box and adapted to be l able section and engaging the screw-seats of operated from the top of the movable section, substantially as and for the purposes specified.

2. In a threshold or door-sill of the charaeter set forth, the combination of a box pro vided with upper horizontal anges and having screw-seats at regular intervals therein, and openings through the bottom thereof, a movable section mounted in said box1 adjusting screws or bolts having their heads exposed through the upper part of said movthe said box, and stops for said adjusting screws, substantially as vand for the purposes specified.

In testimonjT whereof l have signed this specification in the presence of two subscribing witnesses.

GEORGE A. SEELY.
