E. H. JOHNSON BUILDER S HARDWARE Filed Ja n. 23,
M1 im Patented June 9, 1931 ELVIN H. JOHNSON, F WINNETKA, ILLINOIS BUILDER S HARDWARE Application filed January 28, 1930. Serial N'o. 422,696.
This invention relates to builders hardware, and includes among its objects and advantages, the development of a compact and serviceable door holder of the type com- Inonly mounted on the floor, that may be made up either semi-automatic or completly automatic in its action by a minor change in the shape of the latch only.
In the accompanying drawings:
1:) Figure 1 is a plan view of a completely automatic door holder according to the invention;
Figure 2 is a section on line 2-2 of Figure 1;
i5 Figure 3 is a fragmentary detail, illustrating the form of latch for semi-automatic or convertible operation.
In the embodiment of the invention selected for illustration, the door is pro- 2o vided with a hook member 12 fastened in place by the wood screws 14C.
The support 16 for the latch' 18 is mounted on the floor by means of the pedestal 20 receiving a central lag screw at 22 and se- 25 cured against rotation by the wood screw. 24.
The latch 18 is apertured at 26 to receive the hook 12 and operates by gravity to engage and to release the hook. For this purpose the hook is provided with a single cam surface at 28 on which the outer bail 30 of the latch member may ride up to permit the hook to enter and be retained in the position illustrated in Figures 1 and 2.
To release the parts, the door may be '3J given a slight additional outward displacement, which will bring the cam surface 28 against the cam surface 82, which defines the inner edge of the aperture 26 and eX- tends downward and inwardly from said 4o edge. This engagement will toss the latch upward to a. considerable height and there will be ample time for the door 10 to move away and carry the hook 12 beyond the reach of the bail 80 before the latch falls again.
The supporting plate for the hook 12 is extended downwardly at 34 to provide a metal abutment for the end of a plunger 36 housed in the bore 88 of the support 16.
50 The outward movement of the plunger is 'face 32 to hold the latch in the position of vlimited by the enlarged head 40 and the end of the bore 38, and the compression spring l2, held in place by the sealing plug 4a, resiliently urges the plunger 36 and through it the door 10 away from the sup- V55 port 16 as far as the positiondetermined by the end of the travel. 0f the plunger 86 which isa position where the hook 12 is withdrawn far enough to prevent the bail 30 from catching it. e@
In the completely automatic construction of Figures 1 and 2, the latch is provided with a heel 46 to limit its upward movement v by engaging the surface i8 of the support 16. This surface constitutes the bottom of .G5 a housing groove completed by theside walls '50 which house and protect the latch. The
In the convertible o-r semi-automatic construction of Figure 8, contact at 52 is retained, but the heel i6 has been omitted from i5 the latch casting so that the latch can be thrown over into the entirely inoperative position indicated in dotted lines at 54. In this construction it is a simple matter to proportion the parts and the strength of the 2@ spring a2 in suoli a way that there is an ample margin for releasing the hook by movement of the door 10 without throwing the latch high enough to cause it to fallback into the position at 54 rather than forward into operative position. However, since the bail 3() projects a trifle out of the housing defined by the walls it is an easy matter for the user to throw or kick the latch back into theiposition 54 or forward again into operative position.
When the latch is in the position 54 the device still functions as an ordinary bumper to prevent injury to the door when it is swung wide open. i
TWithout further elaboration, the foregoing will so fully explain my invention that others may, by applying knowledge current at the time of application, readily adapt the same for use under various conditions of service. fl
I claim:
1. A support, a latch pivoted on said support, a hook for engaging said latch, said hook and latch having cooperating cam surfaces for lifting the latch over the point of the hook to interlock the parts, and cam surfaces for throwing the latch clear of the hook upon further inward movement of the hook, said cam surfaces comprising two spaced surfaces on said latch and a single surface on said hook; said latch and support having cooperating portions for holding said latch in position to be engaged by said hook, or thrown back out of the way and inoperative, said support housing all but the outer tip of said latch in both positions, and resilient plunger means acting generally parallel to the movement of said hook and housed in said support, and tending to push said hook away from said support beyond the position for interlocking engagement with said latch.
2. A support, a latch pivoted on said support, a hook for engaging said latch, said latch and support having cooperating portions for holding said latch in position to be engaged by said hook, or thrown back out of the way and inoperative, said support housing all but the outer tip of said latch in both positions.
3. A support, a latch pivoted on said support, a hook for engaging said latch, said latch and support having cooperating portions for holding said latch in position tobe engaged by said hook, or thrown back out of vthe `way and inoperative.
