DOOR-STOP.

Specification of Letters Patent.

Application filed September 12, 1910.

To all whom it may concern:

Be it known that we, AUGUST ARENs and ERNEST L. TEIcH, citizens of the United States, residing at New Britain, county of Hartford, State of Connecticut, (post-oice address the same,) have invented certain new and useful Improvements in Door- Stops, of which the following is a full, clear, and exact description.

Our invention relates to an improved door stop device which is generally useful but which is especially useful where it is desired to hold a door slightly ajar.

In the accompanying drawings Figure 1 is a plan View of the two main parts of the device as they would appear when the door is being held slightly aj ar. Fig. 2 is a side elevation of the main parts shown in Fig. 1, a portion of one part being broken away. Fig. 3 is a side elevation of one of the main parts partly in section, showing in dotted lines two different positions of the companion part. Fig. 4 is a longitudinal section partly in elevation of one of the parts.

1 represents what I will term the stopframe adapted to be secured to the upper part of a door casing as by one or more screws 2. This frame, in the particular form shown, is adapted to either a right or a left hand door as will`4 later be seen, but for the purpose of a full understanding, it will be necessary to describe in detail only one side of the frame since the other side may be a duplicate, only reversed. The frame 1 includes an inwardly directed flange 3, preferably formed on the arc of a circle with its center approximately coincident with the axis of the door hinge (not shown). This flange 3 has a further extension or stop shoulder comprising in its preferred form the two spaced parts 4-5. The part 4 is provided on its top side with an easy incline 6 facing the door, and with a stop shoulder 7 facing away from the door. The part 5 has an easy incline 8 facing the door and just outside of the stop shoulder 7. This part 5 at its outer end and on its under side has an easy incline 9.

10 is what I will term the pawl frame adapted to be secured to the upper edge of a door. In'the upper part of the frame 10 is pivotally mounted a pawl member 11, the head of said pawl having a lateral oEset 12 arranged to coact with the inclines 6, 8 and 9 and also with the stop-shoulder 7 previously described. As a matter of fact, in the particular form shown, the pawl 12 has two osets 12 and 12a as shown in Fig. 1, which offsets correspond but are respectively adapted to the opposite sides of the stop frame accordingly as the device is applied to a right or a left-hand door. In view of the fact that the stop-shoulder 12, which coacts with the aforesaid inclines, is on the rear side of the pawl, as shown in Figs. 2 and 4, and cannot readily be seen, it will be sufficient to describe the form of the extension 12 since that is merely a duplicate of the extension 12.

The extension 12a is provided on its upper side and forward end with a rounded but somewhat abrupt nose-like shoulder 14, and on its under side and rear end with an easy incline 15. 16 represents a buffer mounted preferably upon a spring 17 The pawl 11 moves freely up and down but its normal position is determined by the buffe-r upon which it rests as shown in Fig. 4.

Assuming the parts are in the position indicated in Fig. 1, it would be seen that the pawl nose 14 is bearing against the stopshoulder 7 in which position the door will be held ajar. To close the door the operator must first open it until the frame 10 and the pawl 11 are drawn back at least to the position indicated in dotted lines on the righthand side of Fig.r3, the pawl extension 12 riding freely up and over the incline 8. lVhen the parts are in this position the movement of the door toward the door casing will cause the nose 14 to encounter the easy incline 9, which acts to press the pawl 11 downwardly until it passes under the part 5 and similarly under the part 4 until the door is fully closed, at which time the frame 10 and the pawl 11 will assume approximately the position indicated in dotted lines at the left-hand side of Fig. 3. In this posit-ion the pawl 11 is lifted to its normal elevation there being sutlicient clearance space between the incline 6 and the end of the frame to permit the offset 12 to pass. If the door is now opened it is obvious that the incline 15 of the pawl will ride up the incline 6 so that the door will not be retarded during said opening movement, which opening movement can be continued as far as desired, the pawl 11 freely riding over the parts 4 5. Should the door be stopped as soon as the part 12 has cleared the part 4 the nose of said pawl will drop again to the position indicated in Figs. l and 2 and stand behind the stop shoulder 7 to again hold the door slightly ajar. It will thus be seen that while the door may be freely opened and closed at any time, there is one position at least wherein the door may be securely held slightly open. The number of parts et might be multiplied so as to increase the number of stop-shoulders 7 without departing from the spirit or scope of this invention, such multiplication being too obvious to require special illustration. f

It will be understood that the term pawl herein is used generically and should not necessarily be limited to a hinged element, although the hinge element shown is decidedly preferable. It should also be understood that the mere reversal of parts as well as other modifications are contemplated as Within the scope of this invention.

What we claim is:

l. In a door stop device, a stop frame, a stop extension carried thereby, said extension having two easy inclines on one side extending away from the door, a stop shoulder between said inclines the outermost end of the stop extension having an easy incline on its under side, a coacting lmovable member, a frame therefor, said movable member being shaped to ride over said extension when moved in one direction and under said extension when moved in an opposite direction and to encounter said stop shoulder when moved partially over said stop extension in one direction.

2. In a door stop device, a stop frame, a stop extension having two spaced parts carried thereby, each part having an easyrincline on itstop side extending away from the door, `a stop shoulder between said inclines, the outermost part having an easy incline on its under side at its outer end, a coacting movable member, a frame therefor, said movable member being shaped to ride over both parts when moved in one direction and under both parts when moved inthe opposite direction and to encounter said stop shoulder when moved partially over said extension in one direction.

8. In a door stop device, astopframe, a

lateral stop extension having Vtwo spacedy parts carried thereby, each part having an easy incline on its top side extending in the same direct-ion away from the door, a stop shoulder on the outer end of the innermost part, an easy incline on the outer end and under side of the outermost part, a coacting pawl, a pawl carrying frame, a support for the free end of said pawl, said pawl having an easy incline on its under side extending upwardly and outwardly. Y

4. In a Vdoor stop device, a stop frame, a lateral stop extension including two spaced parts, an easy incline on top side of both parts extending in the same direction away from the door, a shoulder on the outer end of the innermost part, an easy incline on the outer end and under side of the outermost part, a coacting pawl, a pawl-carrying frame, said pawl having an easy incline on its under side extending upwardly and outwardly, the inclined part of said pawl being laterally offset, and a yielding support for the free end of said pawl.

5. A door stop device comprising a stop frame and a pawl-carrying frame, a stop extension on the stop frame having a stop shoulder in one surface thereof, a pawl, means to guide said pawl when moved away from said stop frame freely over one surface of said stop extension, means to guide said pawl when moved toward the said frame freely over the opposite surface of said stop extension, said pawl encountering said stop shoulder when moved only partially over one of said surfaces in a direction away from said stop frame, and means to yieldingly hold said pawl in a normal position.
