Feb. 3, 1931, H. STARGARDT noon DETENT Filed June 12. 1929 jy-i Inventor file/2 'z aiyardi A iiomey Patented Feb. 3, 1931 HELEN STARGARDT, F DETROIT, MICHIGAN DOOR DETENT Application filed June 12,

The present invention appertains to new and useful improvements in closure fasteners and more particularly to a novel keeper for maintaining a door in a partially closed position so as to prevent the entry of persons through a doorway, yet permitting face to face conversation between a person on the inside of the door and a person on the outside.

The principal object of this invention is to provide a detent of the character mentioned which is capable of being quickly manipulated to a position for obstructing the door.

Another important object of the invention is to provide a door keeper which is capable of being secured in position without the necessity of having any particular mechanical ability.

Still another important object of the invention is to provide a detent of the character mentioned which when not in use will be dis posed in a position parallel to the floor and out of the path of the door.

After considering the following specification and. claims, other important objects and advantages of the invention will become more apparent to the reader.

In the drawings:

Figure 1 represents a horizontal sectional view through a door and its associated frame- V work, and showin in top plan, the novel keeper in disposition with respect to said door.

Figure 2 represents a fragmentary side elevation of the inner side of a door and showing the novel keeper in door engaged position.

Figure 3 is a side elevation of the novel keeper in extended position.

Figure 4 represents a longitudinal sectional 40 view through the keeper taken substantially on line 44 of Fig. 3.

Referring to the drawings, wherein like numerals designate like parts, it will be seen A that numeral 5 designates a door frame, while numeral 6 represents a horizontally swingable door mounted therein.

The novel keeper consists in construction of a U-shaped member 7 having the inner face of the its bight portion disposed in angular relation with respect to the base side of the 1929. Serial No. 370,202.

said bight portion. The U-shaped member 7 at its bight is provided with a shank 8 in the form of a tapering wood screw. The foregoing describes the stationary section of the keeper, that is the part which is secured by driving the screw 8 into the flooring.

The upper section of the keeper consists of an elongated body 9 provided at one end with a pair of inwardly directed slits 1010 to accommodate the leg portions of the U- shaped member 7 The projections 11 thus formed by the slits 1010 have their end portions bevelled as at 12, the bevelled end of the intermediate projection 11 serving to bear against the angular faces of the bight portion of the Unnember 7 to limit the swing of the body 9. The leg portions of the U- shaped member 7 and the projections 11 of the body 9 are secured pivotally together by the pin 13. The slitted end portion of the body has one side slightly reduced to receive the dust and dirt guard 14: which is secured by screws 15 to the body and which extends over the pivotal connection in the manner clearly shown in Figure l. This card is of spring sheet metal which serves to tensionally retain the body 9 in uprightposition engaged with the member 7.

The free end portion of the body 9 is recessed as at 16 to provide a lip 17.

It will thus be seen that the U-shaped memher 7 is secured by its screw 8 to the flooring in a position with respect to the door 6 as substantially shown in Figure 1. Normally the upper section 9 reposes in the manner shown in dotted lines in Fig. 4, and in this view the shoe 18 of the operator is engaged beneath the lip 17 and moved upwardly when it is desired to move the detent to an extended position. he detent may be also returned to its normal position by engaging the shoe thereagainst and when the keeper is in its normal position, it is outside of the path of the swingable door 6.

Obviously the disposition of the plate 14 will serve to prevent any dirt or dust from entering between the projections 11 and the legs of the U-shaped member 7 which would naturally tend to prevent the most efficientuse of the device.

While the foregoing description is in specific terms, it is to be understood that numerous changes in the specific shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described my invention, What I claim as new is:

1. A door detent of the character described comprising a pair of sections, one of said sections being of U-shape and provided with means whereby the same can be stationarily mounted, the bight portion of said U-shaped section being beveled, the outer section being provided with a leg pivotally secured to the leg portions of the U-shaped sections, said leg being beveled at its extremity so as to uniformly abut the beveled bight portion of the U-shaped member, to maintain the sec tions in alinement when the pivotally mounted section is in extended position.

2. A door detent of the character described comprising a pair of sections, one of said sec-- tions being of U-shape and provided with means whereby the same can be stationarily mounted, the bight portion of said U-shaped section being beveled, the outer section being provided with a leg pivotally secured to the leg aortions of the U-shaped sections, said leg being beveled at its extremity so as to uniformly abut the beveled bight portion of the U-shaped member, to maintain the sections in alinement when the pivotally mounted section is in extended position, the leaf spring on the swingable sections being adapt-- ed to bear against the U-shaped sections, when the swingable section is in extended position to maintain the sections in alinement.

In testimony whereof I affix my signature.

HELEN STARGARDT.
