Purser Assistant Examiner-Edward J. McCarthy ABSTRACT: A one piece portable wedging device with two different tapers, permitting the device to be used with different heights. For example, the device may be used as a door stop, and if one of the tapers does not give sufficient height to permit the device to be wedged in the space between the bottom of a door and the floor, the device may be turned to present the other taper giving a greater height to the device.

PATENTED Aus24 197i FIG. 1

mveuro q TWO-WAY noon sror This invention relates to portable door stops which are wedged between the door and the floor to secure the door against moving. It is also useful in ways mentioned below.

i It is an object of this invention to provide a stop so constructed that two pairs of faces will serve as wedges of different heights, one pair of faces tapering from near zero to the usual height of a door stop, and the second pair of faces tapering upward from the maximum height of the first pair to a height almost twice that of the first pair of faces. The novel part of this invention is the second pair of faces incorporated into a single stop. They permit the stop to function on doors whose clearance above the floor is too high to engage the usual door stop. The use of two heights of wedges in a single stop greatly increases the utility of this door stop and eliminates the need for other heightening means such as blocks or shims.

A preferred form of this invention is drawn to show:

FIG. 1. A top plan view;

FIG. 2. A side view;

FIG. 3. A wedge end view (core not shown in this view);

FIG. 4. A core end view.

As shown in the drawing, the stop has four faces and two ends. Opposite faces form wedges, the low wedge shown in profile in FIG. 2 and the high wedge profile in FIG. 1. All views are arranged in third angle orthographic projection. Any cross section parallel to the ends is a rectangle. The low wedge is at an appropriate angle to wedge doors having floor clearances from nearly zero to the usual height of a door stop. The high wedge continues the approximate angle of the wedge from the maximum height of the low wedge to a height nearly twice that of the low wedge. The door to floor clearance, or other opening, determines the choice of the wedge to be used.

This door stop may be made of any yielding or resilient material of suitable composition such as, but not limited to, rubber or plastic which are now commonly used for door stops. It can also be made of a hard material for other wedging uses. This stop can be made by molding or casting but it is not solid or cored and may have raised or depressed, plain or patte'rned faces, or be otherwise modified within the scope of the claims below.

This stop, in a proportionally reduced size, will function as a window antirattler or, in a proportionally enlarged size, it has other wedging and holding uses.

I claim:

1. A door stop with four wedging faces and two ends, substantially rectangular in a cross section parallel to the ends and so constructed that one pair of opposite faces forms a wedge which tapers from nearly zero to a given height, the given height being the maximum height of that pair of faces and being equalto the usual height of a door stop, and the other pair of faces forms another wedge which tapers from the given height, or a trifle less, of the first pair of faces to a height approximately twice the given height of the first pair of faces.

2. A one piece wedging device with four wedging faces and two ends, substantially rectangular in a cross section parallel to the ends, so constructed that one pair of opposite faces forms a wedge which tapers from nearly zero to a given height, the given height being the maximum height of that pair of faces, and the other pair of faces forms another wedge which tapers from the given height, or a trifle less, of the first pair of faces to a height approximately twice the given height of the first pair of faces which can be used as a window antirattler, a holding device or a wedging device.

3. A one piece wedging device with four wedging faces and two ends, substantially rectangular in a cross section parallel to the ends, so constructed that one pair of opposite faces forms a wedge which tapers from nearly zero to a given height, the given height being the maximum height of that pair of faces, and the other pair of faces forms another wedge which tapers from the given height, or a trifle less, of the first pair of faces to a height approximately twice the given height of the first pair of faces, which is the equivalent of a simple wedge and a supporting rectangular block used for heightening means, or the equivalent of two simple wedges used in combination to obtain an equal height.
