Similar numerals of reference indicate like parts tnrouglioutl the several views on the drawings.
Referring now to the details of the drawings the numeral 1 indicates tlie wall or partition of the tellers cage inr which tlie usual grated Window 3 adjacent thereto. Numeral 4 indicates a movable` shutter or door for closing the grated windowv 2, and numeral 5 indicates a spring roller curtain connected With the shutter 4 adjacent one edge ci the latter for screening the or Utransparent window (not shown) located in the Wall 1 behind the shutter 4 when the latter is retracted to disclose the window 2. f
Numeral 6 indicates the tellers cage entrance door which is slidably mounted in the partition 1 in any suitablev manner, but preferably on rollers, as herein described, said rdoor being adapted to be actuated simultaneously with or independently oi the shutter door 4, as'hereinafter described.y Thenumeral 7 indicates a trap unit for actuating both the shutter 4 and the door 6 when thev two are disengageably connected together, or the shutter door 4 alone when the door 6 is closed the former is to be closed over the windowV 2. Numeral 8 indicates the second trap unit which is adapted to close only the door 6 independently of the shutter door 4. Both of the trap units 7 and 8 are alike in mechanical details and only one of them will be described herein for that reason.
The numeral 9 indicates the cable for actuating the shutter door 4 and which is connected with the latter at l0, said cable being trained over suitable rollers or pulleys lland l2 to lconnect the end thereof with the'counter weight 13, the latter being arranged within the trap unit 7, or
8, the latter including a suitable apertured casing to admit the cable 9 thereto. The numeral 14 indicates a flexible cable for closing the door 6 and it is connected with said door at 15 and trained over the pulleys or rollers 16, 17 and 18, thence into the trap unit 8 where it is connected with a counter weight 13 in said unit. The roller 16 is mounted on the partition l ahead of the cable anchorage 15 to effect the necessary draft on the door for closing the latter which follows the fall of the weight 13 in the trap unit.
The shutter 4 is carried upon the roller trucks 19 and 19 which operate upon the horizontal double track bars 26 and 2l which have their extremities mounted in the brackets 22 and 23 carried by the partition 1, and the door 6 is operable upon said track bars by roller trucks 24 and 25. Both the shutter 4 and door 6 are arranged between the track bars 20 and 2l which are sufficiently close together to maintain the juxtaposition of the members 4 and 6 there-between. Preferably, the track bars 20 and 21 are made of flat metal to facilitate the engagement of the roller trucks 19, 19 and 24 and 25 therewith.
The numeral 26 indicates a horizontal abutment bar connected with the partition 1 and arranged in front of the shutter 4 and grated window 2 to prevent unauthorized inward tiltable displacement of the shutter 4 in either the open or closed position thereof.
The numerals 27 and 28 indicate two pairs of abutment rollers suitably mounted in the shutter door 4 below the track bars 20 and 21 and spaced therefrom suitably to admit of limited upward displacement of the shutter 4 and rollers 19 and 19', said rollers being adapted to engage the under side of the track bars when the shutter is upwardly displaced for any reason, as by an obstruction beneath said shutter when the latter is in motion. Similarly, the door 6 is provided with a pair of abutment rollers 29 and 30 below and spaced from the track bars 20 and 21 and which are adapted to engage said tracks upon upward displacement of the door 6 and to function as stop elements.
Numeral 31 indicates a traction bar disengageably connecting the shutter door 4 with door 6 and rigidly connected with the former at 32. The outer end of the traction bar 31 carries an enlarged head or knob 33 which is engageable with a furcated abutment member 34 xedly connected with the top end of the door 6, said bar being displaceable upward out of engagement with the furcation of the member 34 to release the door 6 from the bar knob 33 to enable independent movement of said door. When the bar 31 is thus displaced from the member 34 it is caused to engage the furcation 35 of the furcated member or bracket 36 which is positioned above the member 34 and rigid with partition 1, whereby the knob 33 is caused to engage the face of member 36 disengageably locking the shutter 4 against closure movement, as is hereinafter described.
The numeral 37 indicates a yieldably mounted wall section of the partition 1 and arranged between the track bars 26 land 21, the upper end whereof is carried upon the two pairs oi roller .trucks 38 and 39 which operate upon said track bars similar to the function of rollers 24 and 25 of door 6.
The partition wall section 37 carries also the abutment rollers 40 and 41 below and spaced from the track bars 20 and 21 which function to engage said track bars to limit upward movement of the wall section 37 when the latter may be upwardly displaced for any reason. The numerals 42 and 43 indicate compression springs which encompass the carrier and guide rods 44 and 45, respectively, which are rigidly connected with the wall section 37, said rods having their ends slidably and tiltably engaging in suitable apertures 48 formed in the guide brackets 46 and 47, respectively, rigid with the partition 1. The wall section 37 is adapted to function as a yieldabie abut ment for the door 6 when the latter is closed upon any kind of an obstruction of limited volume interposed between the edges of said door and said wall section.
Means for positively locking the wall section 37 against yielding movement is provided and may comprise a bell-crank 49 tiltably mounted on said wall section at 50, a vertically arranged and slidable locking bolt 51 connected with one arm of said bell-crank, and a bell-crank actuating pin 52 which is slidably and horizontally arranged in the guide bracket 53, the point of said pin being engageable by a hammer block 54 rigidly mounted on door 6 adjacent the edge thereof. 51 is disengaged from a bolt socket 55 formed in track bar 26, and will drop from said socket when subject to no urge, said bolt being forced into said bolt socket only when the block 54 forcibly engages the point of the pin 52, the latter being operatively connected with the second arm of the bell-crank 49. n
In the event an obstruction is interposed, for any reason, between door 6 and wall section 37, when the former is forcibly closed, or actuated for closure, it then becomes impossible for the hammer block 54 to engage or actuate the pin 52, whereby the said wall section will yield to the right against the springs 42 and 43, as indicated in dotted lines thereof. 1f the obstruction referred to were a mans hand or arm serious injury thereto would thereby be averted.
As heretofore stated the trap units 7 and 8 are alike in mechanical details and only one of them will therefore be described. Numeral 56 indi 1 cates the trap unit casing within which the counter weight 13 disposed for operation when connected with the cable 9. 'When elevated, the weight 13 is supported upon the inner end of a supporting lever 57 which is pivotally mounted in a pair of opposed bearing brackets 58 and 59 exteriorly of the casing 56, said supporting lever being held in a normally horizontal position by a trigger element 66 which is disengageably locked thereto by a notch element 61, said trigger element being pivotally mounted on a shaft 62 which is carried in the brackets 58 and 59. The supporting lever 57 may be provided with opposed trunnion pins 63 and 64 (Fig. 3) to provide the desired pivotal support therefor in the brackets 58 and 59.
The inner end of the lever 57, upon which the weight 13 normally is carried, may be furcated at 66 with a roller 67 mounted in said furcation,
the opposite end of said lever projecting through.A
an opening formed in the wall of the casing 56. Numeral 68 indicates a curved pick-up arm secured to the bottom of the weight 13 by screws, or otherwise suitably by fastener members 69, said curved arm being arranged within the lever furcation 66, the point thereof extending beyond the roller 67 toward the medial portion of said lever and in contact with the roller 67.
The numeral 79 indicates a link operatively connecting the upper end of the trigger 60 with Normally, the point of the locking bolt lli) o r weight tilting the lever 57 to a ho" foot ietf-.al 30 m unted thereon to rock said sliaft.y
Obviously, when pedal S is depressed, t e trigger 60 tilted away from the cas'flg thereby disengaging notch 6l point of the suppe. lever 51, thereby releasing the weight 3 of trigger control weight to fall to the bottom oi the casing 56, whereby shutter 4 is actuated and window 2 closed thereby. Simultaneously the curtain 5 is caused to be uni-oiled and to screen the glass window exposed by the cle. re movement of said shutter 4. The fall of the 13 tilts the supporting lever 57 to an upright position and the weight ol the parts causes the tagger 60 to tilt toward the casing 56 to an inclined position and leaning against the upper end of the lever 57, in which relation parts are at rest. Upon elevation oi the v eight 13 by the electric motor, or other-- wise, as'hereinafter described, the point of the weight arm which projects through casing opening 65, r picks-up the roller 67 in the lever furcation continued elevation of ontal position and causing the outer end of said lever to again engage the notch 61 of trigger 63 which been 'tilted outward by said lever. ln such movement of the parts described the ner end of the lever 57 again functions as support for the weight 13, as is apparent, which is then releasably locked thereon.
The elevation of the weight 13, as described, also rocks shafts 72 and 78, and the levers and members carried thereby, to their former positionswhereby depression of the pedal v will again cause the fall of the weight 13 with the results as described. From theforegoing it will be evident, if the door 6 is open and rod 3l is operatively connected therewith by bracket 34 and knob 33, that the fall of the weight 13 will not only actuate shutter 4 and curtain 5 but also effect closure movement of the `door 6. rind it will also be evif dent,` if the door 6 is closed on that occasion, that vits closure movement, upward displacementof the shutter will occur when it contacts with any such obstruction which may be thrust through the grated windowi adjacent the desk 3, and whereby the shutter 4 will glide over such obstruction and fully close said window. And in such upward displacement of the shutter door the roller trucks 27 and 23 will limit the upward movement of said shutter door. In the event any ordinary obstruction is interposed below the door 6 the rollers 29 and 30 will admit of limited upward displacement of said door, enabling the full and complete closure of said door. And similarly, rollers and 4l will admit of limited upward displacement of the wall section 37.
The trap unit 8 may be operated in any suitable manner to release the weight 13 therein for closing the door 6, but, as illustrated, a lever arm 84 is utilized for that purpose, said lever being rigidly connected with the rock-shaft 72 in said trap unit, as a substitute for the lever 75 shown in Fig. 2 of trap unit 7, and when the lever 84 is swung upward by the operator the weight 13is thereby released and actuation of the door 6 follows such release.
Motor means is provided for opening shutter 4 and door 6, and such means may take the form of an electric motor 85 mounted on a suitable bracket 86, the motor drive shaft carrying a spur gear 87 which meshes with a spurv gear 86, the latter being carried on a bearing pin 39 projecting from a lever arm 90, said lever arm being pivotally carried .at 91 in a bracket 92 supported on the motor bracket 37. The lever arm is provided with a handle 93 projecting laterally therefrom, whereby the gear 88 may be manually swungupward and downward and into and out of mesh with a toothed element 94 which is provided on the horizontal door actuating bar 95, the latter having one end thereof rigidly connected with the door 6. The bar 95 carries also a depending knock--of cam 96 which is adapted to engage the gear 83 to demo-sh Asame from the rack 94 when the door 6 and shutter 4 have been'fully opened and both weights 13 in. units 7 and 8 have been elevated latched in position. Normally, the gear 33 is disengaged from the rack 94 by the weight of the handle 93.
When desirable, the cables 9 and 14 may be locked against movement even though the weights 13 may be free to fall, such locking devices comprising a locking box 97 for each cable, which box is traversed by the cable which is normally free to move therethrough, in either direction.
Each of the cable locking boxes 97 is provided with an L shaped looking lever 93 pivotally mounted ytherein at 99, the lower end or point 160 whereof may be swung into and out of engagement with the cable, at the will of an operator, whereby, when so'engaged with the cable, draft on cable, which would tend to close the door 6 shutter 4, causes Ythe point 100 to force the cable against the wall or? the boi; Q7 and locking the cable rigidly against draft.
Mechanism is provided for opening the 6 independently of shutter 4 and from either the interior or exterior of the tellers cage. Such a means contemplates a lever 101 which is pivot 'lv mounted in a oor bracket or bearing 162 intermediate the lever extremities, the bracket 102 being mounted within the tellers cage, preferably, and said lever being provided with a late eral pedal 103 which projects through a suitable opening in the partition 1 lto the exterior of the cage. As heretofore stated, the door actuating bar 31 is provided with a knob 33 which normally engages the iurcated bracket 34 on door 6. And it has also been shown that the bar 31 is movable upward to cause the disengagement of the bar knob 33 from the bracket 34, and such upward displacement of the bar 31 is effected by a forked lever 104 mounted on the rock-shaft 105, said bar 31 traversing the furcation of said forked lever, and said rock shaft being mounted in suitable brackets 106 and 107 and r ckable by a lever 108 and a link 109, vthe latter operatively connecting the pedal lever 101 with the rock shaft lever 108. Obviously, depression of the pedal. 103, positioned outside of the partition 1, will rock the shaft and disengage the bar 31 from bracket 34 and elevate said bar into the furcation 36 of the bracket 36, thereby releasing the door 6 from the abutment knob 33. The same effect may be provided or produced by actuation of the lever 101 which is accessible adjacent the point of connection with the link 109.
