noon-nnonon' MECHANISM.

Applicationfiled December door'anchor adapted to hold a door at a-pres determined point.

The door. anchor of my invention belongs to, the. brace-bar rather than the plunger class and has. for its object to produce an improved door anchor of the class referred to. Which is positive and efficient in action, easily manipulated by the foot or hand of the operator, and simple means for holding and locking the brace-bar: when in inoperative position.

A further feature of my invention relates to a triangular hole in the brace-bar pivotally receiving a pivot pin adapted to engage the brace-bar in its various functions, and the free end of the brace-bar tapered and encased by a rubber thimble adapted to form a vacuum for cushioning the brace-bar when in contact with the floor to prevent slipping or marring fine fabric floor coverings.

lVith these objects in view the invent-ion consists in certain novel and useful features 1 of construction and combination of parts as hereinafter described and claimed, and in order that it may be fully understood, reference is to be had to the accompanying drawings in which Fig. 1 is an elevational side view of the de vice shown ininoperative position on the door.

Fig. 2 is a longitudinal sectional side view of the device shown in operative position on the door and in contact with the fioor.

Fig. 8 is a fragmentary side view of the device at its pivoted end showing the trian- -gular hole in the brace-bar and its achievements.

Fig. 5 is a side view of the device bracket.

Fig. 6 is an end view of the device bracket.

Fig. 7 is a horizontal sectional View taken on the line A--B of Fig. 2.

Referring now to the drawings in detail, 1 indicates a vertical swinging door upon which the device is adapted for installation. The device comprises a metallic bracket 2 consisting of a base plate 3 perforated for receiving fastening screws or bolts; two upturned lugs 4 adapted to receive one end of a swinging metallic brace-bar 5 a tapered shoulder 6 rigid with the lugs 4 for enga ing the end of the brace-bar 5 and rigidI 1&25: Se al; N 73.

Pivotally mount-ed between the lugs 4 by the pivot, pin 8. is the brace-bar 5 provided at one end with'a'triangnlar hole 9 pivotally receivingthe'pivot pin 8 and the oppositeend unted w t a r er thi ble 0 he,

purpose of obtaining contact with the floor and prevent slipping or marring fabric floor coverings when in operative position. The triangular hole 9 performs several functions. First, when the brace-bar is swung to inoperative position causes it by gravitation to drop down and engage the tapered shoulder 6 and hold and rigidly lock it in a vertical and inoperative position; second when the brace-bar is swung to operative position, and should there be any protuberance in the floor, it will cause adjustment and impinge squarely against the floor; third, when the brace bar is being swung in its various positions, the bearing lines against the pivot pin permits and causes the brace-bar to rotate around the pivot pin with perfect accuracy without binding against the bracket lines, and causes it to automatically seat itself in operative and inoperative positions.

To prevent the brace-bar 5 being forced beyond its straining line as shown in dotted line (3-1) Fig. 2, and becoming locked in operative position and the backward movement of the door toits limit, I provide the hook-shaped lug" 11 to contact with the bracket base 3 and limit-its movement in this direction. Also the hook-shaped lug 11 provides means for manipulating the bracebar by the toe of the shoe of the operator in its various operations. At the free and tapered end of the brace-bar 5 encased in the rubber thimble 10 I provide a vacuum space 12 adapted to form an air cushion for resilient action when in contact with the floor, and obviate the marring of fine fabric floor coverings.

From the above description it will thus be apparent that I have produced a door anchor mechanism embodying the features of advantage enumerated as desirable in the statement of the objects of the invention,

' without departing from the principle of construction or mode of operation involved.

What I claim is: g 1. A door anchor mechanism comprising a bracket adapted to be secured to the door,

a brace-bar, means for pivotally mounting the brace-bar at one end for swinging movement, said, brace-bar at its pivotal connection having a triangular hole for engaging the pivot pin to rotate thereon and obviate binding or sliding effect on its rotating lines, and to automatically seat the bracebar in operative or inoperative position.

2. In a device of the kind described, a bracket having a pair of outwardly-projecting lugs, a brace-bar, means for pivotally mounting the brace-bar for swinging movement, said bracebar having a triangular hole'at its pivotal end for rotating thereon, a tapered shoulder rigid with the lugs of said bracket for engaging the brace-bar and holding and latching it in inoperative position, a boss adjacent said lugs to prevent the free end of said brace-bar contacting with and marring the door, and to align the said brace-bar in engagement with said tapered shoulder when swung to inopera tive position, the free end of said brace-bar being tapered and encased with a rubber thimble forming an air cushion to prevent slipping or marring floor coverings when in contact with the floor, a hook shaped lug integralwith the brace-bar for its manipulation by the toe of the shoe and to avert extreme backward movement when in operative position.

In witness whereof, I have hereunto aflixed my signature.
