15 Claims.

This invention relates in general to burglar proof booths, and more particularly has reference to a device for preventing the taking of valuables either by a burglar or by a holdup man.

t is well known that particularly in outlying and isolated sections there is great danger to the operators of small stands, filling stations, etc., from housebreakers or burglars and from holdup men. This is particularly true of the latter, it being no uncommon occurrence for a lone bandit to hold up a filling station or some other small establishment, force the operator thereof to turn over all cash on hand as well as other valuables, and make his escape before the authorities can be summoned.

Many different ways have been devised in an attempt to do away with the possibility of such occurrences, a few such arrangements being bullet-proof vests for the operators, concealed guns which may be trained on the intruders, hidden burglar alarms, etc. However, these have all proved to possess certain drawbacks and difficulties, particularly in their uncertainty of operation and in the possibility of unwelcome visitors being able to render them ineffective by one means or another.

One object of this invention is therefore to overcome the disadvantages of arrangements previously devised for preventing holdups or for foiling attempted holdups.

Another object of this invention is to provide a safety entrance leading to the storage place for valuables, so that one cannot get at the valuables without looking himself in, and cannot thereafter get out of the booth without knowing the combination for the lock.

Another object of this invention is to provide an entrance of the type mentioned in which a person not knowing the combination of the lock for releasing him from the booth would be almost certain to lock himself into the booth so that he could not thereafter release himself.

Another object of this invention is to provide a bullet-proof booth or place for keeping valua- Another object is to provide a device of the type mentioned in which a person attempting to release one who had locked himself into the same would have to first unlock and enter another portion of the device before being able to release the person who has locked himself in.

Another object of this invention is to provide a device within which valuables may be located, which device can be entered for the purpose of securing the valuables by only one person at a time, from which the valuables may not be secured without that person locking himself in, and from which said person cannot release himself without previous instructions.

Another object of this invention is to provide a means for foiling attempted holdups in which if the operator be forced to enter for the purpose of obtaining the valuables he need not again come out but may sound an alarm from inside the device, and in which if a bandit enters for the purpose of obtaining the valuables he cannot release himself but must be released by someone properly equipped for the purpose.

Other objects and advantages of this invention will become more apparent from the following description taken in connection with the accompanying drawings, it being understood however that the embodiment shown and described is by way of illustration and example only and is not to be taken as in any way limiting the scope or spirit of this invention. The spirit and scope of this invention is to be limited only by the prior art taken in connection with the accompanying claims.

Referring now more particularly to the drawings in which like numerals indicate corresponding parts throughout:

Figure 1 is a horizontal sectional view showing one embodiment of this invention.

Figure 2 is a detailed view similar to Figure 1 illustrating the locking means.

Figure 3 is a sectional View taken along the line 3-3 of Figure 2.

Figure 4 is a plan view illustrating a part of the locking means.

The device embodying this invention is shown in Figure 1 as being a booth for the protection of a cash register 1 or other device for containing valuables. It is provided with walls 2 which surround the booth on at least three sides thereof, and which are preferably made of some bulletproof material so that when a person is inside the booth he will be protected from assault by persons outside. The booth is also provided with a top and bottom which are preferably of the same material as the sides 2.

As will be seen in Figure 1, one side of the booth is left open for a distance suflicient to accommodate the width of two narrow doors 3 and 4. As will be appreciated, these doors 3 and 4 are arranged to be slid back and forth in front of the opening in the booth, each door being wide enough to cover half of the booth and to overlap to a small extent the door covering the other half. The door 4, which is for use only in cases of emergency as will be later described, is slidable by hand to open or closed position as the case may be, but is normally secured in the position shown in Figure 1 by means of a lock 8.

The door 3 which is also a slidable door as has been described is adapted to be operated in an entirely difierent manner. The door 5 which will be seen mounted inside of the booth is mounted on a shaft 6 which is pivoted at the top and bottom of the booth. Also mounted on the shaft 6 are a pair of rigid members or vanes 7 which carry at their outer edges a cylindrical portion 9 which extends between them and forms a cylinder shaped wall from the top to the bottom of the booth.

Mounted on this wall 9 and extending around past the vane 7 to the swinging door 5 is a gear sector 10 which is shown as being of substan tially a semi-circle in expanse. This gear sector is arranged to mesh with a rack gear 11 secured to the back of the door 3. These gears 10 and 11 are preferably arranged near the top of the booth so that persons entering and leaving the booth will not become entangled in them.

Cooperating with the door 5 when it is in the position shown in full lines in Figure 1 is a partition 12 which extends from the rear wall of the booth a sufficient distance to allow it to cooperate with the door 5. It will be seen that the door 5, the vane 7, and the partition 12 serve to divide the booth into two compartments 13 and 14. The compartment 13 is closed at all times except in cases of emergency by the door 4 secured by the lock 8. The compartment 14 has a portion of its outer wall as shown at 15 formed as an are about the shaft 6 as the center. This portion of the wall 15 is so positioned that it is just far enough from the shaft 6 to allow the outer edge of the swinging door 5 to swing freely, but is not far enough from the outer edge of this door to allow anything to pass between the edge of the door and the wall 15. The rear portion of the compartment 14 is preferably provided with straight walls so as to form a space 16 just large enough to receive the cash register 1 and allow sunlcient clearance for the door 5 to pass in the front of it when it is closed.

The partition 12 is provided with a locking means for automatically locking the door 5 whenever this door is moved to the position shown in solid lines in Figure 1. For the purpose or" receiving this locking means and cooperating therewith, the door 5 is provided with a flange 17 projecting laterally therefrom and formed so as to cooperate with the locking means. The partition 12 is provided with an opening 18 and with a U-shaped portion having walls 19 and 20 for the purpose of receiving the flange 1'7 of the door 5. The lock itself is also provided with a housing having a wall 21 substantially parallel to the partition 12, a wall 22 slightly spaced from and substantially parallel to the wall 20 of the U-shaped member, and a portion 23 forming a partition or cross member extending between the partition 12 and the wall 21. Lying between the wall 20 of the U-shaped member and the wall 22 of the lock housing is a plate 24. An opening 25 is provided in the partition 12 to allow the plate 24 to project therethrough for a purpose to be hereinafter described. At the opposite end of the plate 24 from the opening 25 a cap member 26 is provided and is secured to the U-shaped portion of the partition 12 and to the wall 21 of the lock housing. This cap member 26 is adapted to receive and form an abutment for a short compression spring 27 which bears against the edge of the plate 24 to normally force it outward and cause it to project through the opening 25 and beyond the partition 1 It will be seen however that when the door 5 is in the position shown in Figure 2 it will bear against the edge of the plate 24 which projects through the opening 25 and will force it inward against the spring 27.

The lock is provided with a spring pressed bolt 28 which is the only bolt of this lock in use in the normal operation of this invention. This bolt is supported by being passed through an opening in the cross member 23 and a corresponding opening in the wall 22 of the lock housing. It is provided at a point spaced from the cross member 23 with a stop 29 adapted to receive one end of a compression spring 30, the other end of which bears against the cross member 23. It will be seen therefore that the bolt 28 is normally spring pressed by the spring 30 toward the flange 1'] on the door 5. When te door is in the position illustrated in Fi ure 2, openings 31, 32 and 33 are provided respectively in the plate 24, the wall 20 of the U-shaped part of the partition, and the flange 1'? of the door 5, in such position that they will register with each other and receive the end of the bolt 28, thereby locking the door 5 in the position shown. However, when the bolt is withdrawn so as not to enter the openings 31, 82 and 115 33, the spring 27 will force the plate 24 outwardly through its opening 25 and thus serve to move the door 5 to a position spaced somewhat from the partition 12. At the same time that this takes place, the opening 31 in the plate 24 will have 120 moved so that it will not register with the opening in the Wall 22 of the lock housing, and consequently the bolt 28 will be maintained in its unlocked position.

In addition to the bolt 28 the locking means is 125 provided with a second bolt 34 adapted to be used only in cases of emergency. The belt 34 like the bolt 23 is mounted in openings in the cross member 23 and the wall 22 of the lock housing, and the plate 24, the wall 20, and the flange 17 are provided with openings 35, 36 and 37 respectively for receiving the bolt 34. The bolt 34 however is normally held in its retracted position by a slot formed in one side thereof adapted to int-erengage with the cross member 23 until it is dislodged in 135 a manner to be later described. The belt 34 is urged toward locking position, but is at the same time held with its notch 38 in engagement with the wall 23 by means of a spring 39 attached at one end to member 40 provided for this purpose 140 on the bolt 34-, and attached at its other end to the wall 22 of the lock. housing. As will be seen in Figure 3, this spring 39 is inclined with respect to the bolt 34 so as to pull the bolt sideways and force the notch 33 into engagement with the wall 145 23. The openings 35, 36 and 37 are preferably formed somewhat larger in comparison with the size of the bolt 34 which is to enter them than are the openings 31, 32 and 33 in comparison with the size of the bolt 28. This is for the purpose 150 of making it impossible for the door 5 and hence the flange 17 to be moved slightly one way or the other while the bolt 28 is engaged as shown in Figure 2, by a sufficient amount to prevent the openings 35, 36 and 37 from registering. It will be thus possible at all times when the bolt 28 is in engaged position for the bolt 34 to be engaged without encountering the edges of any of the openings which may not exactly register.

It will be noted that the openings 35, 36 and 37 as well as the bolt 34, are preferably square as shown in Figure 4.

Since the bolt 34 as will be later described is not to be provided with any retracting means, a small opening 41 is provided in the wall 19 to allow the insertion of some small tool for the purpose of pushing the bolt 34 back to its retracted position.

Now it is necessary that the actuating means for the lock mechanism just described be such as to be operable by one familiar with its combination, but that it be such that it is inoperable by one not familiar with its combination.

For the purpose of operating the bolt 28, an.

opening 42 is provided through that portion of the bolt which extends above the wall 23. Through this opening 42 there is inserted a lever member 43 which is normally held down next to the wall 23 by means of springs 44 and 45 extending through openings 46 and 4'? respectively in the wall 23 and being attached to the wall 22. This lever 43 is provided with a pair of pins 48 and 49 on opposite sides of the bolt 28 to prevent it from sliding out of the slot in the bolt. A cord or rod 50 is secured at 51 to one end of the lever 43 for the purpose of lifting it, and it will be seen that when this is done the lever 43 will withdraw or retract the bolt 28 from its locking position.

For the purpose of operating the bolt 34 to disengage the notch 38 from the wall 23 and thus allow the bolt to move to locking position, there is provided a second lever 51a, pivoted at 52 to a pair of ears 53 formed by punching outwardly a portion of the wall 23. This lever 51 is provided with an upstanding part 54 which bears against the side of the bolt 34 adjacent the notch 38. This lever 51 is held in such position as to enable the notch 38 to engage the wall 23, by means of a spring 55 attached to the lever 51 at 56, passing through the wall 23 by way of an opening 5'? formed therein, and secured to the wall 22 in a manner similar to the springs 44 and 45. A series of rods or cords 58 are secured to the lever 51, and it will be seen that when these rods or cords are pulled so as to actuate the lever 51, the portion 54 which bears against the bolt 34 will move the bolt 34 so as to disengage the notch 38 from the wall 23, and allow the spring 39 to force the bolt 34 into engaged position.

For the purpose of actuating the rods or cords 50 and 58, there are provided a series of shafts 59 journaled in the wall 21 of the lock housing and extending through and jcurnaled in the partition member 12. These shafts 59 may be of any suitable number and may be arranged in any desired relation with respect to each other. They are each provided on their ends which project through the partition 12 with a knob 60 so that they may be rotated thereby. These shafts 59 are also provided with means such as the tapped holes 61 and 62 for receiving a series of short arms 63 which are correspondingly threaded to enter the tapped holes 61 and 62. It will be seen that each shaft is provided with two tapped holes such as described such holes being spaced from each other, and each of said holes lying in the plane of one of the previously described bolts.

Now all of the shafts 59 are provided with arms entering their respective tapped holes in line with the bolt 34 which may be known as the dead bolt. Each of the arms 63 thus inserted in the shafts 59 is connected to the lever 51 by means of a cord or rod 58. One of these arms 63 however instead of being connected directly by a cord 58 to the lever 51 is connected by a shorter cord 64 to one of the other cords 58. From this description, it will be seen that if any of the shafts with the exception of the one last mentioned be turned in either direction by means of one of the knobs 60, it will serve to lift the lever 51 and thus release the dead bolt 34 allowing it to move to locking position. The one remaining shaft which is connected to one of the cords 58 by means of a short cord 64 will accomplish this same result it turned in one direction, but will not release the dead bolt 34 if turned in the other direction. This will be clearly apparent from an examination of the showing in Figure 3. This last mentioned shaft 59 is also provided with another arm 65 in line with the bolt 28. To this arm 65 is attached the cord or rod 50. It will thus be seen that when the shaft carrying the arm 65 is rotated in one direction it will cause the dead bolt 34 to move to locking position but when rotated in the other direction it will not release the dead bolt but will instead move the bolt 28 from looking position to unlocked position.

From the foregoing description, it will be seen that the locking means just described may be completely unlocked only by the turning of one of the knobs 60 in one direction. If this knob is turned in the other direction, or if any of the other knobs are turned in either direction, it will serve to allow the dead bolt 34 to move to looking position rather than to withdraw the bolt 28 from locking position. After the bolt 34 has moved to locking position, the only way that it may be retracted is by the entrance of someone into the compartment 13 and the insertion of a proper tool through the small opening in the wall 19 to move the bolt 34 back until its notch 38 engages with the wall 23.

Referring again to Figure 1, it will be appreciated that when the swinging door 5 is moved to the position shown in dotted lines, the door 3 will be moved by the gears 10 and 11 to occupy a position directly behind the door 4 as is also shown in dotted lines. When in such position, the vanes 7 and the cylindrical wall 9 will effectually prevent anyone from entering the compartment 13 through the openings left by the retraction of the door 3. However, a person may enter through this opening and may push the door 5 to swing it about its shaft 6 toward the position shown in solid lines. As he does this, however, the door 3 will move back towards its closed position and will eifectually prevent more than one person entering the compartment 14 at the same time. The cash register 1 or other container for valuables is so arranged that it cannot be opened until the door 5 is pushed all the way back against the partition 12, at which position the bolt 28 will thus move into its locking position. and thereby will be locked. This as will be appreciated also looks the door 3 in its closed position, and the person seeking to get the money or other valuables from the container 1 is entirely locked in while obtaining the same.

Having completed his transaction and being ready to leave the booth, it is necessary that he know exactly which of the knobs 60 to turn, and that he know in which direction to turn that knob. If he does not know, and if he turns the wrong knob or turns the right knob in the wrong direction, he will release the "deac. bolt 34 and allow it to move to locking position. He cannot thereafter be released except by someone unlocking the door 4, entering the compartment 13 and inserting a tool in the small opening as previously described. If, however, he turns the proper knob 60 in the proper direction, the bolt 28 will be retracted from its locking position and the door 5 will be swung outwardly by means of the spring 27 pushing the plate 24. It will be appreciated that as the door 5 swings back about its shaft 6, the door 3 will move to its open position and the person who has secured the valuables may leave the booth.

It is to be understood that the space within the booth above and below the cash register 1 may be closed in any suitable manner so as to prevent a person from getting in either above or below the same and not leaving the booth when the door 5 is swung back to its dotted line position.

For the purpose of assuring that the door 5 will remain in the dotted line position shown in Figure 1 when the booth is not in use, and also for the purpose of moving the door back to dotted line position when it is unlocked by turning the right knob 60 in the proper direction, there is provided a counter-weight 66 suspended over a pulley 67 by means or" a cord 68 attached to the door 3 at 69. It will be seen that by pulling on the door 3, not only will the door 3 be moved to open position, but the door 5 will be swung about the shaft 6 to its dotted line position.

It is to be understood, that instead of the cash register 1, any other container for valuables may be protected by this booth. It is only necessary that the opening for the container be so placed with relation to the door 5 that it cannot be opened until the door 5 is in completely locked position. The compartment 16 may be of course as large as is necessary for the purpose of containing the valuables, even taking the form of a large sized vault or room of considerable proportions if necessary. It is only necessary as above stated the door, drawer, or other means separating the valuables from the compartment 14 be so arranged that it cannot be opened unless and until the door 5 is moved to its locked position.

It be seen from the foregoing that a means has been provided for carrying out all of the objects of this invention.

In order to illustrate the method in which this invention will prevent the success of holdups or burglaries, let it be assume that a holdup is in progress. the holdup man or bandit wishes to get the valuables from the booth h mself, he oust first enter the booth as reviously described and lock the door 5 with t'.e door 3 shutting orf his exit. lie may then obtain the valuables, but in order to release himself from the booth he must first select the proper knob 68 and must decide which direction to turn that knob in order to retract the bolt 28. The chan es of his being able to do this are extremely small as will be appreciated, and upon the number of knobs 60 from which he may select. It he lects the wrong knob and the probabilities are extremely great that he will do so, instead of releasing himself he will set the dead bolt 34- in locking position, and he cannot thereafter be released until someone able to unlock the lock 8 and open the door 4 does so and moves the bolt 34 back to its unlocked position.

If the bandit attempts to force the operator to show him the combination before he enters the bootn, it will be seen that it is impossible for the operator to do this, because the knobs 60 cannot be had access to until the door 5 has been pushed back almost to the extent of its movement. Even then, it is only possible for one person to view the knobs 60 at the same time, and thus one person could not point out to another how to work the combination.

If the operator were forced to enter the booth for the purposes of obtaining the valuables, he need only enter the booth and lock the door 5 and then refuse to come out. The booth being constructed of bullet-proof material, there is no way in which persons outside could force him to leave the booth. In this connection, it is also preferred that some sort of alarm connected with the inside of the booth be provided so that an operator thus within the booth, and with bandits on the outside, might sound an alarm and summon assistance.

It will be seen from the foregoing that there is no way in which unauthorized persons can obtain the valuables protected by this booth.

I wish it to be clearly understood that I may make whatever modifications may be necessary in the form and arrangement of this invention without departing from the spirit and scope thereof, and that such modifications are entirely within the concept of this invention.
