VENTILATOR.

Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed March 27, 1905. Serial No. 252,157.

T0 to whom it may concern:

Be it known that I, J AOOB LORENZ, a citizen the advantage of automatically protecting the interior of a house from rain or dust caused by sudden winds when it is located in such a position as to be exposed to the weather.

In the accompanying drawings, in which like numbers of reference denote like parts wherever they occur, and forming a part of this specification, Figure 1 is a perspective view of a house-shutter equipped with my device. Fig. 2 is a fragmentary view, partly in section, with one of the side panels removed, exhibiting the V-shaped slats in the ventilating position. Fig. 3 is a View similar to the last, showing the V-shaped slats in a different position. Fig. 4 is'a fragmentary view, partly in section, showing the manner of attachment of the V-shaped slats to the side panels of the shutter. Fig. 5 is a fragmentary top plan View, partly in section, of one of the slats, showing its attachment to the side panel and also to the controlling-rod. Fig. 6 is a perspective fragmentary detail of the facing to the side frames, which directly receives the ends of the slats; and Fig. 7 is a perspective view showing one end of one of the slats.

This construction may be applied in the partitions of rooming-houses, state-rooms on ships and boats, transoms over doors, doors themselves in the form of a removable panel set in a window-frame upon which the window-sash is closed down, and in a variety of other ways. In the drawings, however, I have illustrated it as applied to an ordinary window-shutter, as the description of the construction'and operation of the several parts in connection with a shutter will sufficiently show how the same can be adapted to or applied in any of the several uses hereinabove suggested or any others that may be appropriate.

The shutter-frame or equivalent structure is shown formed of the side panels 1 and top and bottom cross-pieces 2. The space within this frame is provided with a plurality of V- shaped slats 3, each of which is provided on the inside with perforated extensions 4:, through the perforations 5 in which the staples 6 loop to attach the controlling-rod 7 to all the slats 3, so that they may move or be moved in unison.

Each of the V-shaped slats 3 is pivoted at the union of its arms in the facing-cleats 8, as clearly shown in Figs. 2, 3, 4:, and 5. The means of pivoting may be varied; but Ihave exhibited the same in the drawings as accomplished by means of rods 9 in fixed connection (as by soldering) with the V-shaped slats 3, said rods being located at the bend of the V and extending into the openings or recesses 10 in the cleats 8, there being one such cleat at each side of the frame. The material of which the cleats 8 are made is slightly enlarged or bulges around each of the openings or recesses 10 for the sake of strength.

Each of the V-shaped slats 3 is notched at both ends, as at 11, and receives in said notches the cieats 8, which, as clearly depicted in Figs. 4 and 5, fit closely up to the bend of the V in the slats 3 and fill in all the space between same and the side panels 1, thereby leaving no peepholes or cracks at the ends of the slats. The ends of the rods 9, as will be observed in Figs. 5 and 7, project out into said notches 11, but registering with the recesses or openings 10 are received thereinto.

The cleats 8 are removable from the posi tion illustrated in the drawings, being loosely mounted on the tongue 12, which projects upward from the bottom cross-piece 2 and seats in the recess 10 in the cleats 8, said tongue 12 extending the full length of the bottom cross-piece 2, so as to preclude vision. The upper end of the cleats 8 may be fixed in any desired manner.

Normally the slats 3 will occupy the position shown in Fig. 2, which allows free circulation of the air, but absolutely precludes observation from without of the inside of the room or house so equipped. In case of a sudden Windstorm with accompanying dust, if the wind blows from left to right in Fig. 3 the slats will at once assume the position of that figure, the dust being thus obviously excluded. In like manner and for the same reason rain could not enter, and in case of rain unaccompanied by wind the slats in the position of Fig. 2 would be a perfect watershed and keep the rain out. If the wind blew in a draft through the house and in a direction of from right to left, in Fig. 3, the reverse movement to that above described would result, obviously equally excluding dust and rain.

Having thus described my said invention, what Iclaim, and desire to secure by Letters Patent, is

1. In a device of the character described, the combination of a plurality of notched V- shaped slats, means for pivoting same projecting into said notches, and means projecting into said notches for receiving said pivotal projections.

2. In a device of the character described, the combination of a plurality of V-shaped slats, said slats'having notches at both ends and rods fixed to said slats extending into the notches at both ends, and a frame, pivotal connection with said frame being made by means of the projecting ends of said rods.

3. In a device of the character described, the combination of a plurality of V-shaped slats, said slats having notches at both ends and rods fixed to said slats extending into the notches at both ends, a frame, pivotal connection with said frame being made by means of the projecting ends of said rods, and means adjoining said frame and received in said notches to prevent vision through said notches.

4:. The combination with a frame of an upwardly-extending tongue seating on the lower rail thereof, removable cleats seating on-said tongue, and secured to the side rails of the frame, and V-shaped slats notched at their ends to receive said cleats and being supported thereby. V

5. The combination with a frame of cleats secured thereto, and V-shaped slats pivotally supported by said cleats and being notched at their ends adjacent the apex to receive said cleats.

6. The combination with the frame having cleats, of V-shaped slats pivotally supported by the cleats and being notched at their ends to receive said cleats, and having their movement restricted by engagement of the legs of the slats with said cleats.

7. In combination with a frame, V-shaped slats notched at their ends adjacent the apex thereof, and means for affording a pivotal connection between the slats and frame extending into each of said notches.

8. In combination with a frame, V-shaped slats notched at their ends adjacent the apex thereof, and means carried by said slats and extending into said notches for pivoting the slats to the frame.

9. In combination with a frame, rods having their ends supported thereby,and V-shaped JACOB LORENZ. Witnesses:
