SHUTTER WORKER.

ESPECIPICAI'ION forming part of Letters Patent No. 391,678, dated October 23, 1888.

Application filed Decemherlil, 1887. Serial No. 257.802. (No model.)

To aZZ whom it 72mg; concern:

Be it known that I, VVILLIS BENNER, of New York city,inthe county ofNew York,and in the State ofNew York, have invented certain new and useful Improvements in Shutter Working and Locking Mechanism; and I do hereby de' clare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 shows a view in perspective of a shutter with my shutter-working attachment applied thereto; Fig. 2, a plan view of the same with the top of the mechanism-containing casing removed; Fig. 3, a vertical section of the same on line mcofFig. 2;Fig. 4,21 detail plan view of the shutter-working mechanism with a different form of lock therefor, and Fig. 5 a sectional View of the same on line y y of Fig. 4.

Letters of like name and kind refer to like parts in each of the figures.

The object of my invention is to provide certain improvements in shutter working mechanism, whereby a shutter or blind can be opened or shut and locked in any position desired from the inside of the casing without opening the window; and to this end my invention consists in the shutter working and locking mechanism, and in the construction, arrangement, and combination of the parts thereof, as hereinafter specified.

In the drawings, A designates the frame or casing of a window, which can be of any de sired form and construction, and B designates the shutter to be worked.

In the sill or lower side of the casing is set a flat box or frame, 0, preferably of metal,for receiving and supporting the operative mechanism, to be described hereinafter. The top or lid of this box or frame is best made flush with the outwardly and downwardly inclined upper surface of the lower casing side in which the frame is set. The outer side of the flat box or frame 0 is removed, as indicated in the drawings, so as to make room for the passage of the parts of the mechanism connected with the shutter.

At one corner of the box or frame 0, and near the outer side thereof, is the bevel gearwhcel D, whose arbor D is journaled below in the bottom of frame 0 and above in the bridgepiece E, attached to the frame in any desired way. Attached to this wheel is an arm, F, connected at its outer end with the shutter B by means of the link G, which is pivoted at one end to the shutter and at the other to the arm. Said arm is preferably not straight throughout its length, but near its outer end bends outward and forward in the direction in which the arm swings from the frame 0 in opening shutter B. Vhen the shutter is closed, as shown in Fig. 2. the arm is swung within the box or frame 0 and the link G extends backward and outward from the curved outer end of the arm to its point of pivotal connection with the shutterthatis, the link extends at an angle outwardlyin the general direction in which the shutter is to be moved as it is being opened. The curvein the arm Fallows the outer end of the arm to be swung well around outside of the shutter when the latter is swung open and back, as shown in dotted lines in Fig. 2. The outer end of the arm can then thrust the link so far as to swing the shutter to the limit ofits swing upon its hinges, or back against the building, if desired.

For turning the gear-wheel D to swing arm F and open, close, or adjust the shutter, as wished, I have provided the gear-wheel H, meshing with such wheel D and fixed on an arbor or shaft, I. This arbor or shaft is journaled, as shown,in portions of the box or frame 0, and extends inward therefrom through the casing of the window-sill. On its inner end is a handle or head, I, for convenience in turning it, as desired. Obviously, with the construction dscribed, the shutter can, by turning this handle one way or the other, be opened or closed easily and quickly.

To provide for fastening or locking the shutters open or shut, or in any desired position, I, have two forms oflocking meehanism,either of which can be used.

The form shown in Figs. 1, 2, and 3 consists of a pawl-lever, K, pivoted to the shaft I, and carrying a lug or pawl, 7c, adapted to engage the teeth H on the fixed circular rack L. As shown in the drawings, this lever is at its pivotal end forked to embrace a collar, 6, fixed on shaft I, and its opposite fork-arms are both pivoted to the said collar. .Vith thepawllever and fixed rack, if the shaft I be turned to bring the shutter B into any desired position-open, shut, or partially open said shut ter can be locked from the inside against any movement by simply moving the pawl-lever to bring its pawl into engagement with the rack-teeth Z Z. \Vhen the shutter is to be moved again,the pawl-lever can be moved out of engagementwith the rack by a finger of the hand grasping the handpiece or head I.

In the form of fastening or locking device shown in Figs. 4 and 5 the pivoted pawl is dispensed with. The gear wheel H, which is fixed on shaft I and which meshes with and rotates wheel D, is then provided with a series of gear-teeth, h h, on its inner side, or side toward the turning-handle I. Attached to the ends of two parallel rods, M M, extending on opposite sides of and parallel with shaft I, is the bar or plate N, having on its outer side teeth or projectionsnn, adapted to engage the teeth 7th on wheel II when the plate is moved toward wheel II, as hereinafter described. Said plate preferably extends diametrieall y across the inner face of wheel D, and is provided with a suitable central opening to accom modate thehub h ofsueh wheel. The rods MM pass loosely through suitable openings in the inner side of boX or frame 0, and thence inward beyond the inner side of the window-casing. Upon such inner side of the casing I prefer to place the plate 0, provided with openings 0 0, through which the rods loosely pass. The rodopenings in the boX or frame 0 and this plate will then keep the rods parallel to each other and the shaft I, while leaving them free to be moved longitudinally inward or outward. On the outer end of each of the rods is a head, m, and loose on the shaft I is a sleeve, P, having the two parallel collarspp, adapted to engage the inner and outer sides of the heads at m on rods M M, and also the cross-bar or handle P, parallel with handle I on shaft I. One or more springs, It, on the boX or frame 0, engaging the bar N, force it normally inward, so that its teeth engage those on the wheel H and lock the latter from turning. The handle I? then occupies the position shown in full lines in Figs. at and 5.

\Vhen the shaft I is to be turned to operate the shutter, the handles P and I are grasped at the same time. Such grasping will draw the handle P toward handle I, and, through the engagement of collars p p on the sleeve 1? with heads at m on the rods M M, will draw the bar N away from wheel I-I, so as to leave the shaft and wheel free to be turned by rota tion of handle I. The handle P, being grasped with handle I, is of course turned with it. \Vhen the shaft has been turned to adjust the shutter as desired, the handle P is released, and the springs R R at once throw the toothed bar N into engagement with the teeth h h on wheel II, so as to lock the wheel from further rotation in either direction.

Having thus described my invention, what I claim is- 1. In a shutter operating mechanism, in combination with the curved swinging arm, a link pivotally connected with the outer end of the arm and with the shutter, substantially as and for the purpose shown.

2. In combination with the shutter, a rotary wheel, and a curved arm carried by the wheel, a link connecting the outer end of the curved arm with the shuttensubstantially as and for the purpose described.

3. In combination with ashutter and a shaft projecting within the casing and provided with a handle by which it can be turned, a rotary gear-wheel, a curved arm carried thereby, a link connecting such arm with the shutter, and connecting-gearing between the shaft and the arm-carrying wheel, substantially as and for the purpose set forth.

4. In combination with the shutter, the curved swinging arm and the link connecting the outer end of the arm with the shutter, a rotary shaft provided with a suitable handle, whereby it can be turned from within the window-casing, connecting-gearing between the shaft and the curved arm, and a lock for the shaft, substantially as and for the purpose specified.

5. In combination with the shutter, the swinging 'arm and the link connecting the arm and shutter, the rotary operating-shaft provided with a suitable turning head or handle, connecting-gearing between the shaft and arm for moving the latter as the former is rotated, a pawl-piece carried by the shaft, and the stationary rack, substantially as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of November, 1887.

\VILLIS BENNER.
