Description

July 21, 1942. D. F. WEAVER MOR TISE CONNECTOR Filed 001;. 26, 1940 gmwwhom n ecu/e r Patented July 21, 1942 I STA S PATENT FFICE 3 Claims.

This invention relates to a mortise connector, and it is an object of the invention to provide a device of this kind which serves to securely hold together and increase the strength of all types of wood connections in which a blind mortise or dado joint is used and wherein the device is of a character to enable the same to be substantially hidden or invisible when applied.

It is also an object of the invention to provide a device of this kind which is particularly intended for use in the manufacture of screen doors which are generally subjected to rough usage and wherein the device or connector is so applied and possessing such strength as to prevent the door from coming apart as a result of usage or weather whereby the life of the door is materially increased.

Another object of the invention is to provide a device of this kind provided with means whereby the same may have a dovetail hold in the wood into which it is driven so that the greater the strain or tension exerted the tighter the connection.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved mortise connector whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed. v

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure l is a view partly in section and partly in elevation illustrating a connector constructed in accordance with an embodiment of my invention;

Figure 2 is a sectional view taken substantially on the line 2-2 of Fi ure 1 looking in the direction of the arrows;

Figure 3 is a sectional view taken substantially on the line 3-3 of Figure l, and

Figure 4 is a view in perspective of the connector unapplied.

As disclosed in the accompanying drawing, S

denotes either a hanging or looking stile of a door and T a top rail. The stile S is provided with a conventional blind mortise l in which is received the tenon 2 of the rail T. Coacting with a wall of the mortise l and an edge of the rail T is a connector C which is constructed and arranged to provide means whereby the stile S and rail T are effectively maintained in assembled relation to withstand rough usage and weather without coming apart whereby the life of the door is materially prolonged.

The connector C, as herein disclosed, comprises an elongated substantially rigid metal strip 3 of a width approximating a side edge face of the tenon 2 and of a length greater than the depth of the mortise I so that when the connector C is in applied or working position, anend portion thereof will be exteriorly of the mortise l and overlie an edge face of the rail T.

The connector C is inserted within the mortise l to overlie the bottom wall thereof. The inserted extremity of the strip 3 of the connector 0 is provided along its longitudinal margins with the substantially perpendicularly related flanges 4. These flanges converge forwardly one toward the other but do not have their outer ends in contact while the lower or free marginal portions of these flanges 4 are beveled from within, as at a, to provide sharp or penetrating edges. After the connector Chas been engaged within the mortise l the flanges 4 through the medium of a suitable tool or implement are forced into the stile S through the bottom face of the mortise I and the outwardly converging flanges 4 take a dovetail hold in the stile S so that the strain when exerted in tension causes the flanges 4 to take a more tight hold.

After the connector C has been suitably placed within the mortise l the tenon 2 of the rail T is placed within the mortise and the outer end portion of the strip 3 is tightly held against the adjacent edge face of the rail T by a screw 5 inserted through the opening 6 provided in the outer end portion of the strip 3 and threading into the rail T. As the outer end portion of the strip 3 is tightly forced against the adjacent edge of the rail T, the lip I at the outer end of the strip 3 is forced into the rail T thus assuring a more secure connection or joint. This lip 1 extends transversely across the strip 3 and is disposed in a direction opposite to the direction of the flanges 4. The outer margin of the lip 1 is suitably beveled to provide a sharp or knife edge b to facilitate the penetration of the lip 1 into the rail T.

While I have herein particularly described my improved connectors as being used with a screen door, it is to be understood that they may be used in connection with all types of wood connections in which a blind mortise or dado joint is used.

It is also believed to be obvious that with the use of either of my improved connectors, the same constitutes a substantially invisible lock and if desired can be rendered entirely invisible or secret by mortising the device, as for example, in the edge face of the tenon and plugging over the portion of the device exteriorly of the mortise.

From the foregoing description it is thought to be obvious that a mortise connector constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and used, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts therein shown in carrying out my invention in practice except as hereinafter claimed.

I claim:

1. A mortise connector comprising an elongated strip of a length in excess of the depth of the mortise in which it is to be inserted to allow an end portion of the strip to be disposed exteriorly of the mortise when the connector is applied, penetrating means carried by the inserted extremity of the strip to be forced within a wall of the mortise, the opposite end portion of the strip being provided with means to allow the same to be anchored to the member having a tenon to fit within the mortise, the penetrating means at the inserted extremity of the strip comprising oppositely spaced flanges extending along the side margins of the strip.

2. A mortise connector comprising an elongated strip of a length in excess of the depth of the mortise in which it is to be inserted to allow an end portion of the strip to be disposed exteriorly of the mortise when the connector is applied, penetrating means carried by the inserted extremity of the strip to be forced within a wall of the mortise, the opposite end portion of the strip being provided with means to allow the same to be anchored to the member having a tenon to flt within the mortise, the penetrating means at the inserted extremity of the strip comprising oppositely spaced flanges extending along the side margins of the strip, said flanges being in outward convergence to provide a dovetail penetration.

3. A metallic mortise and tenon connector comprising an elongated strip of a length in excess ocf the depth of the mortise in which it is to be inserted to allow an end portion of the strip to be disposed exteriorly of the mortise when the [connector is applied, penetrating means carried by the inserted extremity of the strip to be forced within a wall of the mortise, the opposite end portion of the strip being provided with means to allow the same to be anchored to the member having a tenon to fit within the mortise, the penetrating means at the inserted extremity of the strip comprising oppositely spaced flanges bent at right angles to and extending along the side margins of the strip, said flanges being bent upon outwardly converging lines from the extremity of the strip to a point substantially onethird the length of the strip.
