SCREEN.

Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed September 13,1906. Serial No. 334,398.

To all whom it may concern:

Be it known that I, CONRAD BAUER, of Pittsbwg, in

the county of Allegheny, State of Pennsylvania, have invented a certain new and useful Improvement in Screens, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical sectional view of a window provided with my improved screens; Fig. 2 is an enlarged vertical sectional view illustrating the operating mechanism; Fig. 3 is a perspective view illustrating the shutter-screen-guide and latch; Fig. 4 is a perspective view illustrating the connection between the shutter-slats; Fig. 5 is a fiont elevation partially in section and partially broken away illustrating my invention; Fig. 6 is a vertical sectional view illustrating the shutter extension arms..

Like symbols of reference indicate like parts wherever they occur.

My invention relates to an improvement in screens and I have shown it as applied to a shutter-screen in combination with a fly-screen for a window, although it may be used in a like manner in connection with other kinds of blinds, and for doors and awnings.

In the drawings 2 represents the shutter-screen, and 3 is the fly-screen, the shutter being adapted to roll on a roller 4 at the top of the window-frame, and the fiyscreen being adapted to roll in rear of the shutter on a roller 5, the roller 5 being mounted a short distance below the roller 4, and both the roller 4 and the roller 5 are journaled at one end in the vertically sliding bar 6,

the journals of the rolls, passing through slots in the stationary bar of the frame 7. Keyed to the journal of the roller 4 is a gear-wheel 8 and keyed to the journal of the roller 5 is a gear-wheel 9. Midway between the gear-wheels 8 and 9 is a gear-wheel 10 which is fixed to a sprocket-wheel 11 and is journaled in the stationary bar 7. The vertically sliding bar 6 is operated by.

means of the lever-arm 12 which is pivoted to a stationary bracket 13 and is connected with the slidingbar 6 by-a slot and pin as is indicated at 14 in Figs. 1 and 2. Extending from the outer end of the leverarm 12 is the rod 15 which is provided witha handle 16 by means of which the rod 15 and lever 12 may be operated to move the bar 6 and to throw the gear- .wheels 8 and 9 alternately into gear with the gearwheel 10 according as it may be desired to roll or unroll the fly-screen or the shutter. Above the gear-wheel 8 is a pin 17 and below the gear-wheel 9 is a similar'pin 18. When the bar 6 is raised and the gear 8 is thereby thrown out of connection with the gear 10, the pin 17 comes between the cogs of the gear-wheel 8 and locks .the same. By the same movement the cogs of the gear-- wheel 9 are released from the pin 18, unlocking the gear-wheel and bringing it into mesh with the gearwheel 10. .The sprocket-wheel 11 is operated by the sprocket-chain 19, which, engaging with the teeth of the sprocket-wheel, passes over the guide-rollers 20 at the top of the window-frame and guide-rollers 21 at the bottom of the window-frame. By pulling on the sprocket-chain 19 in one direction the fly-screen or the shutter, according to the connection of the sprocketwheel 10, will be raised or lowered, and, by pulling on the sprocket-chain 19 in the opposite direction, a reverse action will take place.

The fly-screen may be formed of any suitable material such as wire-netting, and it may be provided with suitable stiffening battens 22, which battens extend' transversely and fit in the guides 23 secured at the sides of the window-frame.

The shutter 2 is formed of transverse slats, preferably I window-frame downward to-a point about one-third of the distance from the top to the bottom, and in swinging guides 28, which extend from the bottom of the guides 27, to which they are hinged by hinges 29, to the bottom of the window-frame. At the bottom of the window-frame the free ends of the swinging guides 28 are connected with each other by the transverse rod 30. On each side of the window-frame, pivoted to the rod 30 are lever-arms 31, the outer end of which arms are pivoted to the vertically movable slides 32, which are adapted to slide on the vertical standards 34 and to be locked thereon at any desired position by the set screw 33. By lowering the slides 32 on the standards 34, the lever-arms 31 will be brought from a vertical to a horizontal position, thus extending the lower ends of the swinging guides 28 away from the window-frame, theguides moving on their hinges 29, and thus forms an awning. When the shutter is lowered audit is desired to lock the same, the spring-lock 35 engages with the lug 36 on the window-sill. The thimbles 26 shown in detail in Fig. 4 secured by the connecting links, keep the slats at an equal desired distance apart and also serve as a protection to the slats themselves, preventing them from being injured during the rolling operation.

The operation of my improved shutter will be readily understood from the foregoing description.

Many variations in the form and structure of the different parts may be made by those skilled in the art, without departing from the spirit of my invention.

The advantages of my invention will be appreciated by those skilled in the art. The blind is not only strong, rigid and durable, but it is also simple and easy of operation.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: 1. In a window-screen, the combination of a roller, :1

screen adapted to be wound on the roller, means for actuating the roller, means for disengaging said roller from the actuating means and bringing it into engagement with locking means, hinged guides at the sides of the screen within which the screen is adapted to move, and devices for extending and securing the guides and'screen outwardly to varying distances from the window-frame.

2. In a window-screen, the combination of a roller, a screen adapted to be wound thereon, a roller and an inner screen adapted to be wound thereon, drive-wheels secured to the ends of the said rollers, an intermediate drivewheei, devices for bringing either of the roller drive-wheels into connection with the intermediate drive-wheel and throwing the other of the roller drive wheels out of conncction with the intermediate drive-wheel, and mechanism for imparting power to the intermediate drive-wheel.

3. In a window-screen, the combination of a roller, a slatted screen adapted to wind on the roller, actuating mechanism and a locking device adapted to be alternately connected to the roller, fixed guides in which the edges of the slatted screen are adapted to move, movable guides hinged to the fixed guides, rigid extension arms one end of each of which is pivoted to the lower end of the swinging guides, and vertically movable slides to which the other ends of the extension arms are pivoted.

4. In a window-screen, the combination of an outer screen an inner screen, a roller adapted to wind the outer screen, a roller adapted to wind the inner screen, a vertically movable housing within which the two rollers are journaled, gear-wheels on the ends of the rollers, an intermediate gear-wheel journaled in fixed housings, de-

vices for throwing the roller gears in and out of mesh with the intermediate gear, a sprocket-wheel fixed to the intermediate gear, and a sprocket-chain meshing with the sprocketwheel.

5. In a window-screen, the combination of a roller, a screen adapted to be wound on the roller, means for actuating the roller, means for simultaneously locking the roller and disengaging the actuating means and for simultaneously unlocking the roller and connecting the actuating means thereto, hinged guides at the side of the screen within which the screen is adapted to move, and devices for extending the guides from the window-frame and for locking the same in position.

6. in a window-screen, the combination with a windowframe, of inner and outer screens, rollers upon which said screens are adapted to be wound, actuating means there- I 8. In a window-screen, the combination with a windowframe, of inner and outer screens, rollers upon which said screens are adapted to be wound, an actuating device therefor, locking devices, and means for simultaneously engaging said rollers with or disengaging them from said actuating device and said locking devices, whereby either roller may'be actuated.

9. In a window-screen, the combination of slats, thimbles fitting on the slats and provided with openings adjacent the top and bottom thereof, and a connecting device for said slats passing through the openings in said thimbles and between the thimbles and slats, whereby the adjacent connected edges of the slats are held in parallel relation in the process of operation.

10. In a window-screen, the combination of slats, thimbles fitting on the slats and provided with slots adjacent the top and bottom of the slats, and a connecting device for said slats passing through said slots and between the thimbles and slats, whereby the adjacent connected edges of the slats are held in parallel relation. v

In testimony whereof, I have hereunto set my hand.
