As shown on the drawings:

A mechanism accomplishing the objects of this invention is shown on the drawings and will now be described, it being untaken along the line derstood that details of this mechanism may be considerably varied to meet the needs of particular installations.

In Figure 14 the reference numeral 1 represents an enclosure such as a bank, store, dwelling-house or the like, which is provided withI a plurality of windows, doors and'ot'her openings thereinto, each of which 'openings is adapted to be closed against entrance or exit by means of a shield or curtain of -steel or other impenetrable material whichis moved into protective position by mechanism and in a manner to be described hereinafter. The main entrance to the room or building which is protected by this installation is preferably provided with a vestibule such as is indicated by the reference numeral 2 in`Figure 14, the entrance to, andthe exit from said vestibule being adapted to beclosed by 'protective shields or curtains of the type lheretofore mentioned. A vdiagrammatic illustration of 'such a vestibule is shown in perspective in Figure 13, and it will be noted that the coustruction thereof is such that the various operatin mechanisms may lbe effectively conceale beneath the Hoor and in the side walls of the vestibule. In Figure 15 I have diagrammaticall illustrated a mail car which is adapte for the protective installation of this invention, said mail car being designated as a whole by the reference numeral 3 and being provided with side door closures 4 of the usual t pe. Extending inwardly from one of sai closures are lateral walls 5 which afford a vestibule entrance, the end of which is adapted to be closed by a `steel protective curtain embodying the principles of the present invention. The closure 4 opposite the vestibule entrance is ofcourse also provided with a similar conW cealed protecting curtain.

In the installation illustrated herein there are two types of protective shields or curtains, each of which is preferably constructed of relatively narrow strips of steel or other substantially impenetrable, fireproof materialz which are hinged together in the manner mdicated by the reference numeral 6 in Figure 10. -The protective .shield or curtain for the outer entrance of the vestibule and the mechanism for operating the same will now be' described in detail. Said protective shield which is indicated by the reference numeral 7 is adapted to be rolled on a suitable roller 8 which is rotatably mounted beneath the floor of the building or other enclosure and which is adapted to be driven throu ha shaft 9 and bevel gears 10 and 11, which' in turn are driven from a motor 12 through an automatically operated clutch 13 and'suitable reduction gearing 14 and bevel gears 15 and 1,6, best shown in Figure 2. Secured to the upper edge of the curtain 7 is a reinforcing strip 17, the outer ends of which are formed to slidingly spectlve enga guide rods 18 and 19which are re.- y mounted ,on .either side of the door or other opening and are concealed in- Side the frame thereof.' The vertical. guide rod or shaft 19 is rotatably mounted and is adapted to be driven through bevel gears 2()y and 21, and a shaft 22, from a motor 23, through suitable reduction gearing 24 and bevel gears 25 which are best shown in Figure 2. This drive from the vertical shaft or rod 19 is transmitted through bevel gears 26 and 27 and an automatically operated clutch 28 to a horizontal shaft 29 which is rotatably mounted above the door or other closure and inside the upper frame thereof.

Mounted on the horizontal shaft 29 near4 each end thereof adjacent the shaft-s or rods 18 and 19 are sprocket wheels 30 and 31 which are res ecti'vely engaged by sprocket chains 32 an 33 which are connected at one end to the reinforcing strip 17 on the curtain 7 and which have Weights 34 and 35 respectively connected to their free ends, the weight 34 being Amovable on a guide 36, and the weight 35 being movable on a guide 36.

The protective shield or curtain installation just described is used in connection with the outerdoor of the vestibule of the ,building, railway car or the like, and is the one which is initially set in operation. 'A slightly different type of protective shield or curtain is used in connection with the remainder of the doors and windows and is also 'used at the inner end of the vestibule. These protective shields which are controlled automatically by means of mechanism associated with the protective shield or curtain 7 will now be described. Curtains or shields 37 similar to the curtainl 7'are provided for each of the window and door frames and said curtains are adapted to be wound or rolled on -rollers 38 journalled on a suitable axial shaft 39 beneath the frame of the door or window. The upper end of each of said llt) curtains 37 is provided with a reinforcing strip 40, the outer ends of which are formed to slidingly engage guide rods 41 and 42 which are mounted inside of the frame of the door or window and parallel to the vertical ortions of said frame. Suitably journalle above the frame of the doorl or window and in alignment with one edge of the curtain 37 is a pulley 43 anda double pulley 144 is similarly journalled opposite said pulley 43 and in alignment with the other edge of the curtain 37. Secured to one end of the reinforcing strip 40 is a flexible member 45 which may consist of rope, chain, cable or any suitable material and which extends upwardly around the pulley 43 and then transversely to the pulley 44, from said pulley 44 downwardly to connection with a boss 46 on a weight 47 which is slidably mounted on a guide rod 48 parallel to the 1rov `of gravity thereon will cause the same to rapidly descend, thus causing a rapid upward movement of the curtain or protective shield 37 to close the window orv door in which said shield is applied. rlhe weight 47 is normally held in raised position by means of a spring latch 50 which is adapted to engage in notches in an extension 51 on the upper end of said weight and which is adapted to be released to release the weight by a link 52 which is operated through a pivoted bell-crank lever 53. When the curtain 37 is moved into operative position by descent ofl the weight 47 the end of the re.- inforcing strip 40 which slidably engages the guide rod 41 contacts a forked arm 54 which is pivotally mounted near the upper end of said guide rod and the movement thus imparted by this Contact with the forked arm 54 is transmitted to a pivoted lever 55 which acts to close a switch 56 connected in the circuit of an electric motor 57 which is adapted to be manually set in operation to rotate the shaft 89 thereby causing the curtain 37 to be rolled on thejroller 38. \A connection between the shaft 39 and the motor 57 is aorded by bevel gears 58 and 59, an automatically operated clutch 60, a shaft 61 and reduction gearing which is indicated as a whole'by the reference numeral 62. Said automatically operated clutch 60 is adapted to be moved into engagement by means of a suitable fork 63 which is connected to a pivotally mounted weight 64, the release of said weight allowing the same to rotate about'its pivot point and causing the jaws of the clutch to be moved into engagement. Said weight 64 is normally 'held in unreleased or upward position by the engagement of a spring latch 65 with notches formed in the upper end of a verltical extension arm 66 on said weight. The

release of said spring latch 65 is effected through a link 67 which is operated by a bell-crank lever 68, one arm of which is pivotally connected to a member 69 `which in turn is connected to a link 70 extending to the lever 55. As a result of this arrangement, the weight 64 is released to move the clutch into operative position upon the movement of the curtain 37 into upward or operative position and the consequent contacting of the forked lever 54 by the end of the reinforcing strip 40.

`When the'curtain 37 is moved to downward or inoperative position by means of the above described operation of the motor 57, the switch 56 is opened and the clutch j 60 disengaged. 'This is effected by the contacting of a pivoted forked lever 71 by the under side of the end of the extension 40. This contacting of said lever 71 acts to rotate the same about its pivot point, forcing the outer end thereof into Contact lwith a horizontal extension 72.0n the member 69, and thus imparting a downward pull on the link 70 to open the switch 56. At the same time the inner end of the lever 71 is moved upwardly, and this upward movement is transmitted to a pivotal connection with an extension arm 7 3 on said weight 64, the weight thus being rotatedl upwardly about its pivot point into such position that the spring latch65 can again engage in one ofthe notches in the extension portion 66.

This upward movement of the weight 64 is of course transmitted through the fork 63 to disengage or receive the clutch 60. Substantially simultaneously with the release of the clutch 60, the Weight 47 will have been moved into position so that the spring latch 50 is engaged in one of the notches in the extension 51 on the weight 47, thus maintaining said weight in raised position. l

A connection effecting the automatic release of the spring latch 50 to allow descent of the weight 47 and movement of the curtain 37 into operative'position will now be described. Connected to one end of the bellcrank lever 53 is a link 74 which extends downwardly to a pivoted bell-crank lever 75 and is connected to one arm thereof.

Connected to the other arm of said bellcrank lever 75 and extending 'substantially horizontally is a link 76 which in turn is connected to one arm of a pivoted bell-` crank lever 77 which is pivotally mounted adjacent the guide rod 19. Extending upwardly from the other arm of said bellcrank lever 77 is a link 78 which is connected to a pivoted member 79, the outer end of which is adapted to be contacted by the end of the reinforcing strip 17 to be moved upwardly into the dotted line position shown in Figure 1, thus causinga release of the spring latch 50 through the connections just described. j

rlihe particular protective shield or curtain 37 and attendant mechanism just described are adapted 'to be mounted at the inner end ofthe vestibule, but exactly'the same installations are adapted lto be mounted in all of the doors and windows of the particular \enclosure to which the installation is applied, and the automatic control for these curtains is effected through a pivoted lever 80 similar to the lever 79 and mounted theree curtain 37.- A connection from the pivoted lever. 80 to the controlling spring latches at the variousdoors and windows is effected through a link 81 which is connected near the outer end of said levery 80 and which extends downwardly to a connection with one arm of a pivoted bell-crank lever 82, the other arm of which is connected to a link 83 which affords, through suitable connections adapted to the particular installation, a connection with the various spring latches similar to the spring latch 50.`

Upward'movement of the curtain 7 is eected in the manner previously described through rotation of the shaft 29 and the connection of said shaft for rotation is made through the clutch 28 which is held in engagement during the upward movementy of the curtain by means ofa pivoted weight 84 which is pivoted at 85 and which is provided with an upwardly extending arm' 86 which is connected to a portion of the clutch 28 so that when said weight 84 moves downwardly the clutch 28 is engaged in operative position. When the curtain-7 reaches the upper limit of its travel, the free end of theweight 84 is again moved upwardly to release-the clutch 28 by contact of the end of the reinforcing strip 17 with a forked extension 87 on said weight which is engaged on either side of the *shaft 19. Said weight 84 is held inupward orcclutch releasing position by engagement of a spring latch 88 with oneof a series of notches formed in an upward extension 89 on said weight 84. A release of said spring latch 88 is effected during the downward movvement of the curtain through a link 90 which is connected tosone arm 'of a pivoted bell-crank lever 91, the other `arm of which has connected thereto a link 92 extending downwardly to a pivoted lever 93, the outer vend of which is adapted to be contacted by the under side of the end of the reinforcing strip-17,1dur ing the downward movement of the curtain. Thus, during the downward movement of the curtain, at the point when the same has 'been moved downwardly sufficiently to move -into concealed position, said lever 93 is contacted to release the spring latch 88, the weight 84 is allowed to move downwardly y and again cause operative engagement oft.. the clutch 28, automatically connecting thev curtain to be again raised through the operation of' the motor 23. This downward movement of thecurtain is also transmitted to a vpivoted T-'lever 94 which is moved 'into position to allow the opening of fa switchA 95 in the'circuit of the motor A12 and at the same time to cause a closing of a switch 96 in the circuit of the motor 23, thus stopping the motor 12 and ceasingthe downward movement of the curtain and at the same time placing the circuit of the motor 23 in such position that the curtain 7 may again be ra1sed.

The operation of the T-lever or plate 94 is effected through a link 97 connected thereto and extending downwardly to a member 98 which has a horizontal extension 99 extending under one end of a pivoted forked lever 100 which is engaged on either side of the shaft 18. It will of course be obvious that the downward movement of the curtain causes the und-er side of the end of the reinforcing strip 17 to Contact the forked end of the lever 100, causing downward movement thereof, said downward movement being transmitted through the link 97 to the T-plate or lever 94. The dbwnward movement of the forked end of the lever 100 of course causes the other end thereof to be moved upwardly, and this upward movement is transmitted to a pivoted weight 101, through a pivotal connection of the o-uter end of said lever `100, with anf upwardly extending member .102 on said member 101. Said weight 101 is pivoted at 103: as the raising of the free end thereof in the manner just described acts to release the 'clutch 13, a connection between the wei ht and the fork 104. When the curtain 7 is rolled down into inoperative position said weight 101 is held upwardly to maintain the clutch 13 in disengaged position by the engagement of a spring latch 105 with one of a series of notches formed in an upwardly extending' member 106 on said weight 101. When the curtain is moved upwardly into operative position the end of the T-plate or lever 94 which is connected to the link 97 is 'contacted by the reinforcing strip 17 and is moved upwardly, thus moving the link 97 upwardly, andr this upward movement o-f the link 97 is transmitted through a bell-crank lever 107 and a link 108 to release the spring latch 105 and thus allow the weight 101 to drop and move the clutch 13 into engaged and operative position. This movement of the T-plate 94 is simultaneously transmitted lclutch being afforded by an or inary 'clutch I to close the switch 95 in the circuit of the motor 12, and to allow the opening of the switch-96 in the circuit of the motor 23.

As has been before stated, the operating Vmechanisms for'the protectiveshield or cur- .2,3, 4 and 13, wherein the reference numeral 109 represents the inner wall of the building, room or vestibule, wherein the reference numeral 110 represents the ,outer walls thereof. The floor is designated by the reference numeral 111 and narrow openings in the floor and in the side walls permit of the free upward and downward movement of the protective shields or curtains. The

narrow opening in the Hoor 111 is preferably normally closed by a hinged strip or spring door 112 which is pushed upwardly into open position by the upward movement of the protective shield or curtain. The narrow openings in the side walls 109 are normally concealed by strips 113 which are guided by the side walls themselves and resiliently held over the narrow openings by light helical springs 114'. The lower ends of said strips 113 are beveled in the manner indicated in Figure 3, so that the upward 4movement of the protective shield or curtain will serve topush the same rearwardly out of the way, compressing the springs 114. Said strips 113 are preferably formed in the manner indicated in `Figure 4 soas to slidingly engage each side of the wall 109, said wall thereby acting as a guide for said strip. The ceiling of the room or the top of the door frame indicated by the reference numeral 115 is preferably provided with a groove 116 in which the reinforcing strip on the top of the curtain or protective shield is engaged when the same is moved into operative or protecting position.

Figures 16 and 17 diagrammatically illustrate the electrical connections which are used in the installation of this invention. Figure 16 illustrates the electrical connection employed in connection with the motorl 23 which is employed for raising the curl tain 7. These connections include a main contro-l or line switchr117 which is preferably locked in a control boX' together with other manual control switches, the switch 96 which has previously been described and an automatic or spring operated switch 118 which is placed in position in the drawer of a cash register, or in conjunction with the door of a safe or vault, or in any other suitable place where unauthorized tampering will cause the same to be closed and the circuit completed.

An alarm bell 119 or any other suitable electrically operated alarm apparatus may also be placed in shunt with the circuit so as to ring or operate when the switch 118 is closedby the unauthorized manipulation of the burglar.

The electric circuit for the motor 12 Figure 17) which is like the motor 57, is used for returning the curtain to inoperative position, and comprises a manual control switch 120 and the reset switch 95. Substantially the same circuit is used in connection withthe motor 57, in this case the switch 56 tal;-

.ing the place of the switch 95.

The operation is .as follows:

The' operation of the device will be obvious from the foregoing description. IUpon the'closing of the spring switch 118 by the burglar or other unauthorized person, the Circuit to the motor 23 is energized, an'd said motor is set in operation to cause an upward movementof the curtain 7. This movement is relatively slow and upon contact of the reinforcing strip 17 with the lever 80, Weights similar to the weight 47 are released and the windows, doors and other openings are closed by curtains similar to the curtains 37. This closing of the windows an'd doors is rapidly effected since the weights like the weight 47 are preferably made heavy enough to cause a fast upward movement of the curtain and upon the doors and windows thus being closed, the burglar will naturally attempt to escapo through the vestibule since the curtain 7 has not yet entirely closedand this offers an apparent avenue of escape. Said curtain 7 however in the meantime has .travelled suiiiciently high to prevent the burglar escaping therepast and ordinarily upon the burglars reaching the vestibule the travel of the curtain 7 will have been suicient to cause the reinforcing strip 17 .to trip the' lever 79 thereby releasing the weight 47 and causing a rapid upward movement ofthe curtain 37. ln attaining this result the speed of the curtain' 7 and the position of thelever 79 are varied in accordance with the size of the room or other enclosure. rlihus, in a large majority of cases the burglar is very likely to be trapped in the vestibule during his efforts at escape. The control of the motors for returning the curtains to inoperative position is of course manually effected through switches simllar to the switch 120 which are all preferably positioned in a looked an'd concealed compartment. Both in the upward and downward movement of the curtain the automatic resetting operations of the switches and clutches are e'ected in the manner previously described.

It will be apparent from the foregoing.

' eration by llawful'.'occupants of the building or the'ilikelinca'se of fire to isolate certain rooms of the building or to close the same against 'draughts which enhance the spread of the fire.

It desired, the entire installation may be disconnected for purposes of repair or in- -spection by opening the manual control switch' 117.

I am; aware that numerous details of construction n'xay be varied through a. wide range'without departing from the principles of this' invention, and I therefore do not .purpose limiting the patent granted hereon, otherwise than-necessitated by the prior art; III claim as my4 invention:
