WALTER- TWEGNER, OF DENVER, COLORABO, VASSIGNOB F Q'NE-HALF T0 WEGNER, OF DENVER, COLOR-A130 .DOORSTOP Application. filed November 17, 1932. Serial No. 642,991.

This invention relates to improvements in doorstops and has reference more particularly to a doorstep designed for heavy duty work, for example, in connection with garage doors and doors for factory buildings, barns, etc.

It is the object of this invention to produce a illoorstop of a simple and substantial construct on that can be readily applied to any door and which can be quickiy adjusted so as to hold the door in open position at any angle from zero to 180 degrees.

Another object or this invention is to produce a doorstep that shall be so designed that the several members of which it is made can be cut rein standard structural steel so as to simplify and cheapen the costof construction and at the same time obtain a deice of great strength and pleasing appearauce.

This invention can be most clearly described and will be most readily understood bv reference to the accompanying drawing in ch it has been illustrated in its preferred i n, and in which: Eig. 1 is a top plan view showing the stop secured to ooor and the latter held in open position, 180 degrees from closed position;

Fig. 2 is a top plan view showing the door in closed position;

Fig. 3 is a view similar to that shown in Fig. 1, but shows the stop adjusted to hold the door in a 90 degree open position;

Fig. 4: is a section taken on line 4-4, Fig. 1, and shows the construction of the latching mechanism; and

Fig. 5 is a section taken :on line 55, Fig. 1.

In the drawing reference numeral 6 designates the wall of a building and numeral 7 one vertical member of the doorframe. A door 8 is secured tovthe doorfraine by means of an ordinary hinge 9. The doorstep 'th t forms the subject of this invention comprises a bracket 10, which is preferably cut from angle iron, and which is secured to the doorframe in the manner shown in Fig. 5. A lever 11 formed from a short section of steel channel bar is pivotally attached at 12 to the bracket 10. An angle iron bracket 13 is attached to the door and pivotal-1y attached to the outwardly extending flange of this bracket is a channel iron lever 14. The free end of lever 1-l is pivotally attached to the lever 11 by means of a pivot 15.. Lover 11 extends beyond the pivot point 15 and ms secured to its outer end a latching device which comprises .a member 16 which is preferably formed from a short section of iron. Tlie hor'izontal flange oi member 16 is pivotally attached to lever 11 by means of a rivet 17 and the vertical flange has an opening 18through whichthe bar 19 extends. The outer end of bar 19 passes through an opening in the outwardly .extending flange 20 of the angle iron bracket whose other flange 21 is secured to the door at a point near its outer edge. The end of the bar 19 that extends through the opening in flange 20 is preferably bent or curved as shown in Fig. 1, and is provided with two radial abutments 22 and 23. Coil springs 24 are located between the abutments 23 and the flange 20 and permit the rod to move slightly in either direction. The function of these springs is to soften any sudden force that is applied to the doors and prevent excessive strains. Bar 19 is provided near its outer end with a notch 25, see Fig. 4. When the door is in open position, the notch receives the lower edge of the opening 18 and is therefore latched against move ment in either direction. For the purpose of releasing the latch, a lever 26 has been provided. This lever consists of two arms bentat substantially right angles to each other. The horizontal arm is provided with an opening for the reception of a rivet 27 that passes through a corresponding opening in the horizontal flange of member 16. A string or chain 28 is attached to the lower end of the vertical arm and this string passes through an eyelet near the outer edge of the door. A ring 29 is preferably secured to (ihe free end of the string and by exerting a pull on this string or cord, the bar 19 is lifted so as to raise it above the lower edge of the opening 18, thereby releasing the latch and permitting the door to close.

The angle to which the door can be opened before the catch becomes effective is governed by the distance X in Fig. 2 and when the stop is attached to the door, the

' latching members are arranged as shown in Fig. 4, after which the door is brought to the angular position at which the stop is to become effective and the bracket 13 located to fit this position. It will be seen by comparing Fig. 2 with Fig. 3, that with the other parts connected in the same manner, the distance X is much shorter in Fig. 3 than in Figs. 1 and 2.

It is apparent from the explanation just made that this stop without any change can be adjusted to hold the door open to any extent between closed position and 180 degree open position as shown in Fig. 1.

When the parts are as in Fig. 8, it is apparent that a heavy gust of wind striking the door will tend to move it in either direction, and this movement will be resisted by the bar 19. The springs 2% will tend to soften the shock which would otherwise be transmitted with excessive force to the doorstop.

he latching mechanism shown in Fig. 4 is merely illustrative as it is evident that the specific latching mechanism can be varied without departing from the invention of which this means forms a single element.

From the above description it will be seen that the doorstop that forms the subject of this invention permits the door to be opened through an angle of 180 degrees and that it can be adjusted to hold the door in any angular open position. By the design of door stop described above, stock material can be employed and the cost can therefore be reduced to a minimum.

Although this doorstop is intended primarily for the larger doors, it is evident that it can also be employed with little doors as well.

Having described the invention what is claimed as new is:

1. In combination with a doorframe and a door hingedly mounted on the frame, a doorstop comprising. a lever having one end pivotally attached to the doorframe, a second lever having one end pivotally connected with the door, the free end of the second lever being pivotally connected with the first mentioned lever, a latching device connected with the first lever, and a bar having one end movably connected with the door, the bar being slidably connected with the latching device, means for interconnecting the bar and the latching device when the door is in open position, and means for releasing the latch to permit the door to be closed.

2. In combination with a doortrame and a door hinged to the frame for opening and closing movement, a bracket secured to the door-frame, a lever having one end pivotally attached to the bracket, a latching device connected with the outer end of the lever, the latching device having an openir' a bracket attached to the door, a lever having one end pivotally connected with the last named bracket and having its other end pivotally connected with the first mentioned lever at a point between its ends, a second bracket attached to the door ad acent its outer edge, the last named bracket having a flange provided with an opening, a bar having one end extending through the opening in the bracket, the bar having an abutment on each side of the flange, a spring between each abutment and the flange, the bar also passing through the opening in the latching device, means for interconnecting the bar and the latching device when the door is in open position and means for releasing the latch to permit the door to be moved to closed position.

3. A doorstop comprising, in combination, a lever, a bracket pivotally attached to one end of the lever for making connection with a doorframe a lever having one end pivotally connected with the first lever, a bracket pivotally connected with the second lever for making connection with a door, a latching device connected with the first lever, a bar slidably connected with the latching device, one end of the bar having means for making connection with a door, the bar and the latching device having means for effect ing an interconnection for preventing the bar from sliding in the latching device, and means for rendering the latching device inoperative.

4. A doorstop comprising, in combination, a lever, a bracket pivotally attached to one end of the lever for making connection with a doorframe, a lever having one end pivotally connected with the second lever for making connection with a door, a latching device connected with the first lever, a bar slidably connected with the latching device. a bracket slidably connected with the bar near one end, the bracket having a flange through which the bar extends, an abutment on each side of the flange, a spring between each abutment and the flange, the latching means having an opening through which the bar extends, means for interconnecting the bar and the latching means to prevent relative movement in the direction of the bar, and means for releasing the interconnection.
