J. P. GOODFELLOW WEATHER STRIP Filed June 2o, 195e l Patented July 2, 194D WEATHER STRIP Joseph P. Goodfellow, Bellingham, Wash. Application June 26, 1938, Serial No. 214,758

1 Claim.

strips in which the strip or shutter is hinged to the bottom` edge of a door and is held in inoperative position whenlthe `door is open, and is automatically moved into and held in operative positionwhen the door isclosed.` u

The main `object of the invention is to provide a new and improved weather-strip construction to eliminate the use of the raised floor sill or threshold in common use to` provide clearance forthe lower edges of doors in swinging over carpets and other floor coverings; I

A further object is to provide a weather-strip construction of this type in which the weather strip and its operating mechanism are concealed` in the lower edge of thefdoor while the latter is in open position.

, Other objects of the invention will become apparent as the detailed description thereof proceeds;` I H i Inthe drawing:

Figure 1 is a fragmentary perspective View of the lower part of a door illustrating the only part of the weather strip visible while the door is in open position;

Figure 2 is a fragmentary section of the weather Strip mechanism taken lengthwise through the lower ends of the Stiles and the bottom rail of the door;

Figure 3 is a fragmentary transverse section taken on the line 3 3 of Figure 2;

Figure 4 is a section similar to Figure 3, but showing the strip operating mechanism in a different position; and

Figure 5 is a fragmentary, vertical section taken transversely of the strip and its pivot support in the positions occupied thereb-y while the door is open.

As shown in the drawing, the door 6 is hinged at one of its edges to the stile I of a door frame. The lower edge 3 of the door is shown in Figures 2, 3 and 4 as spaced away from the surface of the iioor 9 at a distancenecessary to secure clearance for the bottom edge of the door in swinging over carpets or other.` iioor coverings. Usually, this clearance space would be occupied by a threshold which this invention is intended to eliminate. The lower edge of the` door is provided with a groove It; and the lower ends I of the outer edges of the stiles II and I2 of the door are countersunk to receive the hanger plates I3 and I4, respectively. These hanger plates, when in operative position, are flush with the said outer edges of the respective stile II and I2` and are secured` in position by means of the (Cl. -67) This invention relates to that class of weather a screws I5 with their lower ends flush with the bottom of the groove I0.

` The hangers I3 tnd Ill are formed in pairs having apertured lugs I6 and Il projecting downwardly from the lower ends of the hangers to 5 rod I8, a sheet metal strip`2ll is bentaround the ll).`

rody I3 for the greater part of its periphery and is then extended on opposite sides of the strip` I9. to form the clamping plates 2l` and 22 which may be suitably secured to the strip I9 by rivets or other Suitable securing means 23. ing plates andstrip form a shutter for sealing the lower ends of outside or inside doors against Wind, rain, snow or dust.

As shown in Figure 2, the clamping strips 2i and 22 and the strip I9 are recessed to a depth 20 equal tothe thickness of the hanger platev It to permit the shutter to extend across the `stop shoulder formed by the rabbet `of the door jamb 'I` at the hinged side of the door. At the striking side of the door, the clamping strips 2| and 22 25 are cut away to form a' recess 24 around the downwardly projecting lug I6 on the hanger plate I3. This recess 24 is extended inwardly a suiicient distance to receive the trip camv 25. 'Ihis means that the recess in the shutter at 30 the striking edge of the door has a depth equal to the combined thicknesses of the hanger plate I3 and the trip cam 25.

The trip cam 25 is larger in diameter than the diameter of the rod I3, and is provided with `a radial slot 26 tting snugly over the three `thicknesses of material formed by the weather strip I9 and clamping plates 2I and 22. 'Directly above the trip cam 25 and back` of the hanger plate I3, the edge of the striking stile II of the doo-r is provided with a recess 27 into which projects a spring abutment 28 formed integral with or suitably secured to a stud 29 pivoted in the hanger plate I3. The abutment 23 is bored transversely of its pivot axis to receive slidably the upper end of a pin 3B, provided near its lower end, with aange 3I adapted to form a support for the lower end of `a compression spring 32, the upper end of which contacts with the 5 abutment 28.

Belowthe flange` 3I, the pin 3D is ground or shaped to a chisel edge seated in a notch 33` formed in the upper part of the trip cam 25. The lower part of the trip cam 25 is provided 55 The clarnp- 151 35g Continued movement of the door inwardly 00 f surface of the floor 9 and suitably secured thereto by means of the screw 40. The trip stud 31 is adapted to be adjusted vertically in the plate 39 and locked in adjusted position by means of a lock nut 4I.

The door is shown in Figures 2 and 3 in its closed position and with the shutter I9 inoperative Contact with the floor 9. 4In Figure 4, the

door is shown in position whereV the trip cam has been operated by the trip stud as the door is swung outwardly from closed position to move the shutter I9 upwardly into concealed position in the groove I0. Continued outwardmovement of the door from the position shown in' Figure 4 would leave the shutter I9 in the concealed position shown in Figure `4; and the shutter would be so held during the open position of the door by the pressure of the pin 30 against the trip cam in a direction laterally displaced with `respect to the common pivot axis of the rod I8 and cam.

Closing movement of the door yfrom open position to that shown in Figure 4 will iirst` cause the projection 36 to slide over the 'flat top of the trip stud 31 with the shoulder 35 moving into Contact with the sharp edge of the trip stud.

closing position causes the shoulder 35 to engage the'sharp edge of the trip stud 31 and rocks the trip cam 25 about its pivot axis into the closing position shown in Figures 2 and 3 of the drawing. While the door is closed, the pressure of the spring 32 on the ange 3I of the pin 39 maintains the trip cam in the position shown in Figures 2 and 3, the axis oi the pin 30 being then laterally displaced to the opposite side oi the pivot axis of the rod I8 from that occupied in the open-door position shown in Figure 4.

In order to avoid the necessity for using a very heavy construction of pivot rod III/'and clamping means for securing the shutter I9 thereto, the groove I is formed so that the outer periphery of the sheet which clamps the shutter I9 to the rod I8 is in slight frictional contact with the square corner formed by the intersecting edges Y of the groove I0 adjacent, the pivot rod I8. The

assembled shutter is flexible along its free edge and rigid lengthwise. When this shutter is in open-door position, itneed only be stiff enough to support its own weight.A When the door is closed, a plane bisecting the said corner angle is substantially coincided with the plane of the shutter I9 containing the pivot axis of the rod I8. 'Ihe intersecting sides of the said corner angle act as a V-block to hold the shutter rigid in all directions. This construction makes it possible to have close seating contact without binding and a minimum of friction.

The invention as disclosed herein is exceptionally simple, light and inexpensive. It is to be understood, however, that it is not to be considered as limited to the details of construction shown in the drawing nor in any other way except as indicated by the scope of the claim appended hereto.

What I claim` is:

In a weather strip for the` bottom edge of a door including a pivoted shutter, means for 0perating the shutter comprising a member secured to the shutter, said member having a double faced peripheral cam, one face radial to the laxis of the shutter and the other face perpendicular to the rst face whereby said member canbe rocked in opposite directions in passing a strike member secured to the floor, said member having a detent diametrically opposed to the cam and a spring impelled pivoted and slidable pin engaging said detent whereby the member is resiliently held at each extremeof the cam throw. v
