Application filed. July 28, 1909. Serial No. 509,994.

To all whom it may concern:

Be it known that 1, DANIEL ANTHONY, a citizen of the United States, and a resident of Greenwich, in the county of Fairfield and State of Connecticut, have invented a new and Improved Shutter or Fire-Shield YVorker, ot which the following is a full, clear, and exact description.

This invention relates to certain improvements in workers for shutters or fire shields, and more particularly to certain features ot construction, whereby the worker may be used in connection with shutters or tire screens on windows set deeply into the wall of the building.

My improved worker operates to swing the shutter or shield outwardly from the window casing, so that it can lie against the reveal of the wall near the window opening.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specication, in which similar characters ot reference indicate corresponding parts in all the iigures.

Figure 1 is a horizontal section and partia-1 plan indicating the construction and operation ot the device, this section being taken approximately on the line 1 1 of Fig. 2; Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1 and passing through the upper part of the window easement to indicate the manner of supporting the shutter; Fig. 3 is a plan showing one of the worker arms in detail; Fig. t is a vertical section through the worker arm shown in Fig. 3, this view being a section on the line 1 4 of Fig. 3; Fig. 5 is a plan of a guide cleat which is attached to the shutter or tire shield and which connects with the arm shown in Figs. 3 and l; Fig. 6 is a side elevation of the guide cleat; and Fig. 7 is a cross section on the line 7 7 of Fig. 3.

Referring more particularly to the parts, and especially to Figs. 1 and 2, 1 represents the wall of a building near a window opening in which a window easement 2 is set. The window easement may be provided with vertically sliding sashes 3, as shown, which may be supported in the usual manner by counterweights a moving up and down in the easement. The outer side of the window is closed by a pair of shutters, such as the shutter 5 indicated in its open position and lying against the outer face or reveal 6 of the wall near the window opening.

l My improved shutter worker may be used in connection with any form ot shutter or tire shield, which is used with a deeply set window, and which is capable to swinging outwardly against the outer surface of the wall at one side orn the window.

In the accompanying drawings, I have illustrated a form of worker in which the arm is extensible to tit shutters or shields set various distances back into the wall, and have also illustrated this form in connection with my improved extensible hinges constituting the subject-matter of my copending application, Serial No. 509,993, tiled July 28, 1909.

By making both the hinges and the arms extensible, the shutter may be mounted and operated irrespective of the depth to which the shutter swings inwardly beyond the outer surface of the wall of the building. These hinges 7 have main leaves 8 connected by pintles 9, and each hinge has a plurality ot threaded openings 10. The main leaves are mounted to slide in angle brackets 11, which latter have iianges 12, for engaging with the edges of the leaves. The brackets 11 have webs 13 which engage with the leaves, and in addition they have flanges 14: disposed at right angles to the web and attached by suitable fastening devices 15 to the shutter. Diagonal braces 16 connect the webs and flanges 14:, and clamping screws 17 extend through slots 18 formed inthe webs and into the openings 10. rIhe hinges constitute no portion of the present invention, and are illustrated in connection with my improved worker only to bring out more clearly the advantage of' forming my worker arm extensible.

At the inner extremity of the hinge the angle bracket is attached to a hanger seat 19 which is in the form or' a strip attached to the side of the window easement. In the upper part ot' this strip 19 a pocket 20 is formed in which there is mounted rotatably a worm 21, said worm being arranged upon a horizontal axis. This worm is provided with a sprocket wheel 22, and a sprocket chain 9.3 passes over this sprocket wheel and passes through the window easement to the interior, at which point the chain hangs down, as indicated in Fig. 2, so that it will be within reach or" a person in the interior.

1` erases @n the outer side of the strip 19, a bracket 2l is mounted, on which there is mounted a worm wheel on a vertical shaft or pintlc 2G. To the lower end ot this pintle 2G an extension arin 2T is rigidly secured. The details ot this arm are shown in Figs. .f3 and rlfhe arm is 'formed ot a body piece or main piece Q8 having a square socket 99 which is received on a square neck 3() formed on the lower end or the pintle or shaft 2G. The body piece 2S is of channel form so that it presents Aflanges 31 on its edges connected by a web The web is provided at suitable points with threaded openings 33 which are adapted to receive removable clamping bolts 3l. rl`hese bolts are adapted to pass through slots which are formed longitudinally in an extension piece 3G, as will be readily understood.

lf provide tour of the threaded openings 83, and three slots, as shown. These threaded openings are arranged in pairs, and in Fig. ilthe clamping bolts are represented as placed in the outermost pair. The extension arm 3G in this view is shown in its midpcsition with respect to this adjustment oi. the clamping bolts Sie. rthe slots 35 will evidently permit the ezrtension arm to be adjusted. out tarther until the inner ends et the slots come against the clamping bolts, or the extension arm may be adjusted inwardly in an opposite direction. lt desired, the bolts 3st may be moved into the innermost pair oi openings, when similar adjustments ot the Xtension arrn may be had. The outer end ot the extension arni or bar 36 is provided with a pin 3T having a roller 3 which .is received in a slot 3f) which extends longitudinally in a guide cleat rett). rihis guide cleat is attached to the t'ace of the shutter which is disposed adjacent to the wall when the shutter is open, as indicated in Fig. 1. rlhe guide cleat is attached in a horizontal position by means oit a flange all which extends throughout its entire length. At the end of the guide cleat which is adjacentto the. hinge, the cleat is formed with a laterally projecting neck d2, and the slot 89 runs out into this neck, as shown. Art the point where the slot 39 runs out into the neck it terms a gradual curve or arc 43 which guides the roller into the neck, as will be readily understood.

lil/lith the shutter in the open position shown in Fig. 1, it will be evident that it the chain is pulled in the proper direction the worm 21 will rotate in such a way as to rotate the wheel 25. The shaft ot' the wheel 25 being rigid with the arm Q7 will tend to swing the arm 9,7 inwardly. 1n this way the arm will be made to exert a pull upon the shutter tending to swing it in toward the window. 1n this way the hinges which support the shutter will be flexed and the shutter can then be further swung inwardly until it closes the window, as indicated by the dotted lines in Fig. 1. @n account ot the slots 35 ot the extension bar otl the arm the arm can be adjusted so as to suit the particular building to which it is applied, that is, it' the wall is unusually thick 'the extension arm can be further extended, and vice versa.

rThe laterally projecting neck l2 is very important, for if it were not present the roller 3S could not operate eli'ectively to open the shutter, for in its outward swinging movement in opening the shutter the roller would tend to slide out in the slot and would simply become jammed. With the laterally. projecting neck, however, the slot presents an edge disposed substantially at right angles to the plane ot the shutter, and against this edge the roller exerts its opening torce.

daving thus described my invention, 1 claim as new and desire to secure by Letters l)atent,-
