April 5, 1932. H. D. NORRING DOORSTOP PLATE Filed Feb. 9, 1929 INVENTQR' ATTOENEX Patented Apr. .5, 1932 HO RD n. NORRING, F MI vNEAroLIs, .MINNESOTA :oooRscror 'r AT-n Appli'cationifiledFebruary 9,1929. Serial No. 338,722.

My invention relates to doorstop plates par ticularly adapted for use in doorfraines but alsoapplicable for use as a stop for hinged lids or covers of various kinds havinga frame stop member The main object is to provide a plate with adustable means to compensate for sagging or mis-alinement of the door or other hinged member as hereinafter fully set forthand'as illustrated in the accompanying 0 drawings, in which',, W Fig. 1 is atop view of my improved doorstop plate in operative position on a door frame, the latter being shown in dotted lines only.

Fig. 2 is a vertical face view of my device assembled with its adjustable plate, in cen tral position relative to the base plate.

Fig. 3 is a sectional view about as on line 3-3 in Fig. 2Yand added thereto a portion 120 of thedoor frame in section, also an adjacentlock-containing portion of a door held in locked, closed position.

Fig. 4 is an enlarged face view of the main plate of my device, and its auxiliary plate shown in dotted lines only and in a fixed lowered position.

R'eferringto the drawings by reference numerals, 5 designatesa vertical door frame member havingthe usual doorstep. strip 6 againstwhich the free edge part of a door 7 is stopped, said edge part of the door provided with a lock including the door knob 8 for releasing-the usual spring actuated. bolt 9.

, 10 is a lock bolt normally below bolt '9 and actuated into or outof locking position in the stopplate. My device comprises a main plate 11 fixed as with screws 12 in the face of the door frame 5. Usually said frame is recessed as 53 to provide for free movement door-knob plate havingthe keyhole 14.

HP is the usual outer lip of the plate 11 (see Figs. 1 and 2) for the knob-actuated bolt 9 to engage and be pressed back as the door closes, the outer end of said bolt riding frictionally on the face of the plate 11 until the door is nearly closed and subsequently the bolt is projected into the plate aperture.

Furthermore in the use of my device, when a door shrinks, for example, its free edge may recede from the door plate but this may readily be allowed for and my face plate 15 brought to proper fixed position by simply inserting flat shims or Washers (not shown) between the plates 11 and 15.

The threaded holes 17 are preferably grouped in staggered arrangement as shown and the countersunk holes in plate 15 made oversize so that it is possible to set plate 15 in a slightly tipped or angular position if it should happen that the bolts 9l0 are not in proper vertical alinement.

I claim:

1. A device of the character described, comprising a base plate adapted to be fixedly attached to a door frame member, said base plate having an aperture adapted to lie over a recess of said door frame member for receiving a door bolt, a face plate for said base plate adapted to be situated opposite said recess of the door frame member when said device is associated with said door frame member, said face plate being capable of selective adjustment both vertically and horizontally upon said base plate to each of aplurality of different positions thereon and having an aperture lying over the aperture in said base plate, and means for positively and fixedly attaching said face plate to said base plate against the possibility of accidental movement at any selected one of said plurality of different positions to which said face plate is capable of adjustment.

2. A device of the character described, comprising a base plate adapted to be fixedly attached to a door frame member, said base plate having an aperture adapted to lie over a recess of said door frame member for receiving a door bolt, a face plate for said base plate adapted to be situated opposite said recess of the door frame member when said device is associated with said door frame member, said face plate being capable of selective adjustment both vertically and horizontally upon said base plate to each of a plurality of different positions thereon and having an aperture lying over the aperture in said base plate, and means for fixedly attaching said face plate to said base plate at any selected one of said plurality of different positions to which said face plate is capable of adjustment, said attaching means including a plurality of spaced, threaded holes adjacent each end of one of said plates adapted to be selectively entered by attaching members each of which passes through a hole in the other of said plates.

3. A device of the character described comprising a base plate adapted to be fixedly attached to a door frame member, said base plate having an aperture adapted to lie over a recess of said door frame member for receiving a door bolt, a face plate for said base plate adapted to be situated opposite said recess of the door frame member when said device is associated with said door frame member, said face plate being capable of selective adjustment longitudinally, transversely and obliquely upon said base plate to each of a plurality of different positions thereon, and means for fixedly attaching said face plate to said base plate at any selected one of said plurality of different positions to which said face plate is capable of adjustment, said attaching means including a plurality of threaded holes arranged in staggered relation adjacent each end of one of said plates adapted to be selectively entered by attaching members each of which passes through a hole in the other of said plates.

In testimony whereof I affix m signature.
