position out of the way of the door locked there-' by, to the end that the door may be operated without the necessity of removing the lock.
Still another object of the invention is to prcvide a portable look of this character which may be readily swung to its active position, novel means being provided for holding the arm in its active position against the door to prevent opening the door.
With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.
Referring to the drawings Figure 1 is an elevational view illustrating a lock constructed in accordance with the invention and positioned on a door, the lock being shown in its locking position.
Figure 2 is an elevational view of the lock, il-
lustrating the pivoted arm thereof as swung downwardly out of the way of the door locked thereby, to permit the door to be opened.
Figure 3 is a sectional view taken on line 33 of Fig. 1.
Figure 4 is a sectional view taken through the pivot pin of the lock.
Figure 5 is an elevational view illustrating the rear surface of the lock.
Figure 6 is a perspective view of the portable lock constituting the subject matter of the present invention.
Referring to the drawings in detail, the lock embodies a supporting plate 5 which is formed with a right-angled portion 6 from which the spaced prongs I extend, the prongs 1 extending at right angles with respect to the right-angled portion 6.
Pivotally mounted on the supporting plate 5, is the bar 8 which provides the locking arm of the device. As shown, the bar 8 is connected with 1 into the circular portion of the opening.
the supporting plate 5, by means of th pivot 9 which is formed with a square shank, and a head Iii at the outer or free end of the pivot pin 9, the head resting against the bar 8, to hold the bar to the supporting plate.
As shown, the bar 8 is formed with a circular opening ll of a diameter to accommodate the square shank of the pivot pin 9 in such a way that the bar 8 may pivot with respect to the supporting plate, and be moved from the position shown by Fig. 1 of the drawings, to its unlocked position as shown by Fig. 2 of the drawings.
The opening H is of the keyhole type, and is provided with an extension formed with straight walls 12 that accommodate the straight edges of the square shank of the pivot pin 9, as shown by Fig. 4. When the bar 8 is in its locked position, the bar is moved with respect to the square shank of the pivot pin, to hold the bar 8 in a horizontal position as shown by Fig. 1.
, With the bar 8 in this position, it would be impossible to move the bar 8 to clear the door, and permit the opening of the door, without moving the bar 3 to bring the square pivot pin 9 With the bar 9 in this position, it is obvious that the bar 9 will swing downwardly out of the path of travel of the door swinging to its open position.
When using the portable lock, the supporting plate 5 is positioned over one edge of the door rame, in a manner as shown by Fig. 1 of the drawings. It may be desirable to so position the supporting plate that the prongs I thereof may be driven into the door frame to secure it in position. However, after the supporting plate has been properly positioned, the bar 8 is swung upwardly in front of the door to prevent the door from swinging to its open position.
A rubber block such as indicated by the reference character it may now be positioned within the space between the bar 8 and the door, to insure against damage to the finish of the door, should the door be moved into engagement with the bar 8.
From the foregoing it will be seen that due to the construction shown and described, I have provided a portable lock which may be readily and easily positioned by persons unfamiliar with mechanics, to look a swinging closure by a locking means other than the usual door lock carried by the door.
What is claimed is:
A portable lock for swinging closures, comprising a supporting plate having a right-angled portion terminating in prongs extending therefrom in parallel spaced relation with the supporting plate, a pivot pin extending from the supporting plate, the shank of the pivot pin being square in cross section, a locking bar having a keyhole slot in which the shank of the pivot pin operates, the keyhole slot being disposed longitudinally of the locking bar, said shank engaging the Walls of the slot, holding the locking bar in its horizontal locking position over the closure, one end of the locking bar being extended at right angles providing a finger piece, and said prongs and right-angled end portion being fitted over one edge of a door frame securing the supporting plate in position on a door frame.
