MOUNTING FOR THE LOVTER ENDS Q1? DOUBLE-ACTING HINGED-DOORS.

Application filednugust 28, 1924.

is so formedthat the door is only removable V in one position thereio'f and the weight of the door serves to maintain the door, when in normal or closed position, in its proper position with respect to the door frame.

A further and more specific object of the invention is to provide a floor plate for use with double acting spring hinges which is constructed in separable sections, one of which carries the spring abutment lug of the hinge these sect-ions being so engaged with one another so that when the door is in one position they may be separated and the door thus removed from its mounting without bodily removing the floor plate from the floor, as is usual.

These and other objects we attain by the construction shown in the accompanying thawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention and wherein Figure 1 is a fragmentary perspective of a door frame having a door mounted therein employing a floor plate constructed in accordance with our invention, the door being illustrated as partially shifted to mount or demount the same from its hanging. V

Figure'Q is a fragmentary perspective showing the floor plate and door in their normal positions;

Figure 3 is a plan View of the floor plate;

Figure: 41 is a longitudinal sectional view through the floor plate;

Figure 5 is a transverse sectional view therethrough.

Referring now more particularly to the drawings, F generally designates the floor of a dwelling and H the head sill of a door frame mounted in the wall W of the dwelling. Mounted in the frame is a door 16 having mounted therein at its lower end a double acting hinge 18 of the usual construction and having at its upper end a Serial No. 734:;681.

socket 15 forthe reception of the pin 14 of a pivot plate 14. The character P generally designates a floor plate'for use in attachingthe stud 17 ofthe double acting hinge 18 to the floor to prevent rotation thereof and thereby cause the spring action, usually provided in these doors for holding the door in open or closed position if moved to a predeteri'nined degree or for closing the door if it is opened to a lesser degree on ither side of the frame.

The. floor plate P is of considerably greater width than the thickness of the door and is formed in two closely fitting sections and 11. The plate section 10 is substantially Ushaped while: the plate section 11 is complementary thereto to produce a plate substantially rectangular in form and close the space between the arms of the U. This plate ection 10 is provided with openings 12 for the reception of securing elements whereby it may be attached to the floor. The plate section 11 has formed therein an opening 1.3 of a size and shape to receive the lug 17 and is attached to the lug by upsetting the lug as at 13, at the under surface of the plate section 11 so that this pllatp section 11 is permanently attached to tie ug.

As is well known to those familiar with the art, the pin and socket mounting at the upper end of door mountings of this character provide for vertical movement of the door. Such vertical movement is usually a necesary part of the operation of the hinge 18. In mounting a door employing a floor plate constructed in accordance with our invention, the hinge 18 and socket are mounted upon the door while the pin plate 141 and section 10 of the floor plate P are attached to the head sill H and to the floor F respectively in their proper positions. The door is then placed in the doorway at an inclination .so that the pin 14? may engage in the socket 15 after which the inner end of the plate section 11 is engaged between thearms of the plate section 10 and slid into its proper position. If, upon trying the door, it is found that changes are necessary therein to provide a proper fit of the door, the door may be removed by reversing this operation and sliding the plate 11 from the plate 10 without the removal of securing elements of any sort. It is pointed out that when the door is in its closed position, the weight of the door being arranged at one side of the pivot will cause this weight to be applied in a direction to force the plate 11 into its position in the plate 10. When the door is in open or partially open position, the weight of the door acts to force this plate to one side or the other so that it binds solidly against the plate section 10, preventing any accidental longitudinal movement of the section 11. When the door has moved to its open position wherein it is held, the tension of the spring (not herein illustrated and usually applied over a cam in the double acting hinge 18) is relieved and accordingly there is very little tension placed against the plate 11 enabling the same to be readily removed. The plate P must seat upon the surface of the floor and not be countersunk therein.

It will, of course, be obvious that the construction hereinbefore set forth is capable of a certain range of change and modi fication without materially departing from the spirit of the invention and we accordingly do not limit ourselves to such specific structure except as hereinafter claimed.

WVe claim lvleans for mounting the lower ends of double acting hinged doors having a pin and socket connection with the door frame at their upper ends and having a hinge arranged at the lower end of the door, the hinge including a downwardly projecting operating lug, a lJ-shaped floor plate per1nanently secured to the floor and a plate permanently attached to the operating lug of the hinge and adapted to rest upon the floor, the last named plate fitting between the arms of the first named plate and being movable into or out of engagement therewith by a movement in the general direction of the width of the door opening.

In testimony whereof we hereunto affix. our signatures.
