SHUTTER-BAR.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed April 11, 1905. Serial No. 254,956.

To all 707110777, it natty concern:

Be it known that I, JAooB W. TRIPP, a citizen of the United States of America, and a resident of New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Shutter- Bars, of which the following is a specification.

My invention refers to improved shutter bars or workers.

The object is to provide simple and efficient devices for opening window-shutters and for securing same when open or shut or when in any desired intermediate position, the manipulation of the parts being accomplished in an easy and convenient manner; and the invention consists, essentially, in the construction, arrangement, and combination of parts, substantially as will be hereinafter described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a view in elevation, showing my improved shutter-worker applied to a pair of blinds, the latter being open. Fig. 2 is a sectional plan view of the same. Fig. 3 is an inside representation of the shutter-worker, the parts being in the position which they occupy when the shutters are closed. Fig. 4 is a reverse sectional plan view of the same. Fig. 5 is an enlarged detail view of the extension-bar with its clips provided with antifriction-rollers. Fig. 6 is an enlarged detail representation of a latch on one of the shutters for fastening the same. Fig. 7 shows a modified form of the pivoted arms. Fig. 8 is a modified form of the latch. Fig. 9 is a detail of the pin.

Similar numerals of reference designate corresponding parts throughout the different figures of the drawings.

In order to illustrate the practical application of the invention, I have delineated in the drawings by way of example merely a window-opening 2, a window-sill 1, and a pair of shutters 3 3, hinged at the sides of the opening 2 by means of the hinges 4. In Figs. 1 and 2 the shutters are open, and in Figs. 3 and 4 they are closed.

Reaching from one blind 3 to the other is a horizontal bar or rod consisting of the intersliding parts 5 5, each of which has a clip 6, which embraces the other part, so that I thus provide an extension-bar which adjusts itself automatically as to its length accordingly as the shutters open and close. The ends of the extension-bars 5 are fastened to the blinds 3 3 in a manner to be presently described. Each clip 6 is provided with a casing 18, firmly secured thereto and containing a ball or roller 19, which rolls on the surface of the adjacent member 5 in order that as the two parts or members 5 5 of the extensionbar adjust themselves interrelatively the working of the clips over the parts may take place easily and smoothly and without friction. This horizontal extension-bar is locatedat any suitable point in the vertical height of the shutters 3, being preferably about a third or one-half way up from the bottom or at about the height of the top of the lower sash.

Firmly secured to the inner faces of the shutters 3 are the horizontal brackets 7. A suitable number of bolts, screws, or other securing devices is employed with each of these brackets 7 to rigidly aflix the latter to the shutters. Brackets 7 are provided with outwardly-projecting arms 9, in the ends of which are pivotal points for the attachment of the movable bars 10, having handles 14. The ends of the extension-bars 5 5' contiguous to the shutters 3 are pivotally connected to the brackets 7 by means of pins 8. Furthermore, I find it convenient to employ angle-irons 13, which are fastenedby means of bolts or screws, to the shutters 3, as indicated in Fig. l, and the same pivot-bolts 8 which connect bars 5 to brackets 7 pass likewise through the horizontal legs of the angle-irons 13. These an gle-irons 13 may be omitted, if desired; but in conjunction with the brackets 7 they furnish an additional strong support for the extension-bar.

The extension-bars 5 are provided at points a short distance from the brackets 7 with one or more perforations 25. The movable bars 10, which are pivoted, by means of bolts or pivots 12, to the outer ends of the bracketarms 9, are provided each with a plurality of perforationsll. By grasping the handles 14: on the inner ends of the bars 10 and pushing outwardly thereon the shutters 3 may be opened to a greater or less extent, and by bringing one of the perforations in the bar 10 into coincidence with the perforation 25 in the extension-bar and then inserting the pin 15 (see Fig. 9) through the coincident perforations the blind 3 can be rigidly held in the position to which it has been adjusted. Obviously the blinds are movable independently of each other, and thus capable of adjustment in the same or different positions, it being thus possible to bow them to a greater or less extent or to open them widely. The object of providing the brackets 7 with arms 9, project- -ing horizontally outward therefrom at right angles to the faces of the shutters, is to carry the fulcrum of the arms 10 a suflicient distance from the centers of the hinges 4:, on which the blinds turn, to enable the one manipulating the blinds to do so easily and quickly and with the expenditure of but a little effort, inasmuch as such a position for the fulcrum of each bar furnishes a large amount of leverage. It will be understood, however, that when the pivotal point of the bars 10 is thus removed to a distance from the face of the plane of the shutters there is left a certain amount of' movement, equal to the distance between said pivotal point and the face of the shutter, where the arms 10 cannot be utilized to lock the shutters at the desired angle by bringing their perforations into coincidence with the perforations of the extension-bar, inasmuch as the pivots 12 and end of arms 10 will have reached the extension-bar, and in order to provide for the locking of the blinds while moving through this are I have added to the brackets the perforated segments 16, which furnish a row of perforations 17, extending from the face of the shutters 3 to the pivotal. points 12. By the provision of these perforated segments it is possible, in closing the blinds after they have been swung around to a point at right angles to the wall where the pivotal points 12 have crossed the extension-bar 5 5, to still lock either or both shutters in any desired position by bringing one of the perforations 17 into coincidence with the extension-bar perforation 25 and then using the retaining-pin by thrusting it through the coincident perforations as before. (See dotted lines in Fig. 2.)

In Fig. 6 I have illustrated one form of fastener for locking the shutters in closed position. This fastener consists of a latch 20, situated in a recess or slot 24: in the shutter 3 and hung on a pivot 23. The outer end of the latch 20 is shaped as a handle 21, while the inner end 22 is formed as a hook and is adapted to engage the members 5 5 of the extensionbar. When the second shutter is closed-that is to say, the shutter which ordinarily has a cleat to fit over the first closing shutter-the latch will engage the extension-bar, and the shutters can then only be opened by manipulating the handle 21. Oftentimes it is convenient to have this latch project through the slot 24, as I have shown it in'Fig. 6, so that the shutters can be opened from without, as by a fireman in case of a conflagration. At other times, however, the handle 21 will be omitted and the slot 24 out only partly through the shutter, so that the latch can be operated only from the inside of the blind. This is shown in Fig. 8. Various modifications may be made 1n my invention. The bar 10 may be provided with a series of lugs 30, as shown in Fig. 7, instead of with perforations 11, the object of these lugs 30 being to engage the perforation in the bar 5. In this case the under side of the arm 9 will be rounded, as indicated in Fig. 7, and a bolt 12 employed in lieu of bolt 12. The object of rounding the under side of the arm 9 is to enable arm 10 to'be lifted enough to cause the lugs to engage the perforation 25.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a shutter-worker,the combination with an extensible rod, of means on the shutters for supporting the ends of said rod, said means having projecting arms, and bars pivoted to the outer ends of said arms, and means for securing the said bars at different points to the extension-bar during the opening or closing of the shutters.

2. In a shutter-bar,the combination with the shutters, of an extension-bar consisting of intersliding members, said extension-bar being movably connected to the blinds, and said members of the bar being provided with clips having antifriction devices.
