OF SORANTON, PENNSYLVANIA.

LATCH.

T 0 all whom it may concern:

Be it known that we, WILERED G. GREG- ORY and ROBERT H. Human, citizens of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Latches; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to looks, and especially to light locks for the purpose of securing screen doors and objects requiring similar fastening.

The objects of our invention are to produce a simple andinexpensive screen door, or other fastening which shall be composed of few parts, and shall be of simple construction and easily fired to the door.

A further object of our invention is to produce a door latch which may be locked in position by a catch. of peculiar and novel construction.

Another feature of our invention is a catch for holding the latch in position, the catch being provided with a dowel upon its inner side adapted to snap into shallow dowel holes to fiX the catch movably in a locked or unlocked condition.

With these and other objects in view our invention comprises novel constructions combinations and arrangements of parts hereinafter fully described and claimed.

We achieve these results by the device illustrated in the accompanying drawings, in which Figure 1 is an elevation of our door latch applied to a door. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a vertical section through the center of the staple plate.

Similar characters refer to similar parts throughout the several views.

Referring to the drawings 1 represents a portion of a door to which our device is fas toned.

2 is the door stop and 3 the door frame.

The latch a is bent at right angles, the lower portion, serving as a spring bent at 5, to partially inclose the post 7 The spring ortion of the latch 4 terminates in a curved end 6, adapted to rise in striking upon the post 7, and travel over the post upon impact thereon until it settles down in contact upon Specification of Letters Patent.

the post, thereby holding the door firmly in position.

A post 7 is firmly fixed in a staple plate 18 having short spurs or staple points 9-9 at either end engaging the door stop 2 on which the plate 18 is mounted. In the center of the plate 18 is a hole 10 to receive a screw 10. The spurs 99 are short, relative to the length of the screw 10, so that when the screw is driven into the wood work, thus fas tening the plate, the one operation of driving the screw also sends the spurs 9-9 into the wood work, and by the single operation fastens the plate 18 at three points.

Locked on the plate 18 and above the post 7 is a catch 12 fastened by a screw 16 at its center and adapted to move pivotally thereon. On the under side of the catch 12 is a dowel 17 and the plate 18 is provided with a lurality of cavities 15 into which said owel fits. The catch 12 is loosely affixed. to the plate 18 by the screw 16 so that the catch may rotate upon its pivot 16 and be held closely in frictional contact, by the screw 16. The catch 12 has an outwardly turned finger 13 at one end thereof, and at the other end is provided with a handle 14 also turned outward and adapted to be manually moved. The catch 12 being held closely, as aforesaid, to the plate 18, can nevertheless be moved to rotate on the screw 16 and in doing so the dowel 17 travels around the plate in close proximity thereto and on meeting the cavities 15 snaps into them, thus removably locking the catch. The course taken by the dowel 17 is shown by the circular dotted line on Fig. 1. It is thus found that the catch can be locked, not only in the position in which it is shown in Figs. 1 and 3, but can also be locked in the transverse position as shown by the dotted lines in Fig. 1.

The latch 4 may be fastened by means of the screw 4 or by any other efficient means.

It will be seen by means of this construction the plate 18 will be firmly secured. to the door stop by means of the spurs and its fastening screw.

What we claim and desire to secure by Letters Patent of the United States is 1. In a fastening of the kind described, the combination of a spring latch, a post therefor, a pivotally mounted catch, a plate upon which the catch may rotate, a dowel, and

removably fix the catch in a locked or unlocked position.

2. In a device of the character described, the combination of a staple late, inwardly turned spurs at the ends of the staple plate, a post rigidly fixed to the lplate, a catch pivscribed, a plate fastened upon the door stop 15 I 1 otally mounted on the p ate and provided l l l having a post projecting t erefrom, a catc pivoted on said plate adapted to have its end moved to a position over said post and a spring latch projecting from the door adapted to engage said post and be locked thereto by said pivoted latch.

In testimony whereof We affix our signatures in presence of two Witnesses.

With a handle on one end and an outwardly turned portion at the other end, dowel holes in the plate adapted to receive and hold the catch in a locked and unlocked position and a dowel on the inner side of the catch to engage With said holes.
