Description

. E. N. DAULTON 7 'DOOR MEGHANISM Filed Oct. 18 1924 Patented Aug. 3, H326.
UNITED stares ERNEST N. DAULTON, OF FITCHBURG, MASSACHUSETTS.
DOOR MECHANISM.
Application filed October 18, 1924. Serial No. 744,464.
The principal object of my invention is to provide a very simple but efficient mechanism for holding and releasing a door, such as a garage door, so that it may be released by a vehicle approaching the door without the necessity of the operator of the vehicle leaving the latter.
A feature of my invention is a single member directly engaging and holding the door closed and directly engaged by a vehicle to release the door for opening.
Another feature is that the portion of the member which is engaged by the vehicle is located substantially above the ground so that said member will not be accidentally operated by a person walking on the ground and so that it will not become clogged by dirt, snow or ice.
Another feature is that I provide a very simple releasing mechanism for releasing a sliding door.
Other features will be pointed out below.
In the drawing:
Figure 1 is a perspective of a door mechanism embodying my invention;
Figure 2 is a partial elevation, partly broken away, of the door and the mechanism to open it; and
Figure 3 is a sectional detail.
The garage door A is slidably hung by rolls aarunning on track a the latter being suitably mounted within the garage. \Veight B is attached to cord 5 which runs over pulley b and which is attached by eye 6 to the door A, the weight tending to open the door, that is, to slide it to the left in Figure 1.
To the bottom portion of the door is suitably attached a metal plate D having a central perforation d registering with a recess a in the door.
Attached to the body of the garage is a plate E having a projecting circular threaded shank e upon which is pivoted hold. ing and releasing member or lever F, which is held on said shank by washer and nut f.
Lever F has one end 7'' shaped to enter the perforation in plate D and to enter said recess in the door, and has its other end f headed and located substantially above the ground and projecting outwardly sufficiently to be available for direct engageing the lever in such position that the head f will be properly located above the ground for direct engagement by a vehicle. If desired the nut f may be screwed up tightly enough to press the washer f against lever F so as to permit movement of the lever by the vehicle but to hold the lever frictionally in any position in which it may be put.
When the door is in its closed position the head f is available for direct engagement by the vehicle which pushes said head inward and consequently moves end 7 out of engagement with the door whereupon the weight B acts to slide the door to its open position permitting the vehicle to enter the garage without the necessity of the operator leaving the vehicle.
lVhat I claim is:
1. A device of the character descr ibed comprising a sliding door; a member mounted on a stationary central pivot. one,
end thereof directly engaging the door to hold it closed and the other end being available for direct engagement by a vehicle to move said member out of holding engagement with the door.
2. A device of the character described comprising a sliding door; a movable member directly engaging the door to hold it closed, said member having a portion located substantially above the ground and available for direct engagement by a vehicle to operate said member to release the door.
3. A device of the character described comprising a sliding door; a lever mounted on a stationary central pivot, one end thereof directly engaging the door to hold it closed and the other end being located substantially above the ground and being available for direct engagement by a vehicle to operate said lever to release the door.
4. A device of the character described comprising a door; and a member mounted engaging the door to hold it closed, said member having a portion available for direct engagement by a vehicle to move said member out. of holding engagement With the door.
5. A device of the character described comprising a sliding door; and a movable member directly engaging the door to hold it closed, said member having a portion available for direct engagement by a vehicle to move said member out of holding engagement With the door.
