THRESHOL DILLUMINATOR.

To all whom t may concern.'

Be it'known that l, CHARLES E. Moons, a citizen' of the United States, and a resivdent of the city of New York, borough of Manhattan, in the county andState'ofNew York, have invented a new and lmproved' rl`hrcshold-llluminator, of which thev following is a full, clear, and exact description.

This invention relates to certain improvements in passenger conveyances such, for instance, as elevators in buildings, railway cars yor the like, and the invention contemplates certain features of advantage in thev nature of improvements over the `invention disclosedin Letters Patent of the United States, No. 885,942, issued to me on April as, 190s.

vAmong the objects ofthe present invention is to improve the constructionand operation ofthe illuminator'casmg whereby the fsame is adapted to occupy a minimum 1l is a vertical sectional view of one of the.

amount of room and has lighting facilities for the particular'purposes of the invention superior to any device previously proposed and which also is more reliable.

Another object of this invention is to improve the means for controlling the-time at which the light becomeseifective with re'- spect to the controlling mechanism of the` moving vehicle.

The .invention also. contemplates improved features of construction in various details hereinafter more fully set forth.

The foregoing and other objects of the inventionwill hereinafter be more fullydev i scribed and claimed and illustrated in the' drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the viewsi.

such as when the controlling lever not shown in this view is in running position; Fig.

. At 10 I show a car having la doorway 11 and a threshold 1 2., Said 'doorway may 85 Fig. 5 is a transverse section taken on the line 5 5 of Fig. 4; Fig. '6 is a diagram of the electric connections; Fig. .7 iS afront velevation of the illuminator casing; 8 is a vertical section on theline 8-8 of Flg. no

7 and Fig.-9 is a transverse section of the same on the line 9-9 of Fig. 8.

The several parts yof the device may be made o f any suitable materials, and the relative sizes and proportions, as well as these general design of the mechanism, may be varied to a 'considerable extent without de- 'onelectric railway cars .or other forms of passenger vehicles, and hence while l'may ttt for convenience of expression use the terms elevator or .elevator car, such terms are to be interpreted broadly lenough to cover any device to which my Iinvention may be applied 4and 'in other respects the terms of 8o the c laimsare to be 'given an interpretation as broad as the state of the art will warbe closed by a car door butv since such door forms no part of the present invention the .same is not shown. l show, however, at 13 an operating lever which is symbolicv of any suitable hand operated controlling mecha- 9o 'i nism whereby4 the elevator conductor con-v trols the operationor movements'of the car or any of the parts associated therewith such for instance .as thecar door or shaft gate, in any Well known orapproved manv-ner.- Said lever 13 is connected to a shaft 14 journaled as usual beneath the floor of the car and theaxisof said shaft constitutesA the `pivot around -which theflever may swing in 'the arc of a circle in either direction from 100 the normal or stopped position shown in Fig. 1.

t 15 I show an illuminator casing of` peculiar form |located conveniently at either Side Of'the doorway 11, and having an elon- 105 in the same circuit 17 the light from said llo Patented Bec.. lll, i915a Application filed. october i, i913. i serial No. 792,753.

lamps being adapted to be thrown or flashed out from its elongatdopening and 4 across ythe threshold of the 'carf and the landing at which the car is being stopped. The light being caused t flash` out as above. described serves a numberl of important purposes among which ar'e, first, to indicate not only f to the conductor but to the occupants of the .car that the car is bei-ng stopped and therelight ci -fore the conductor is'assisted in bringing., his` car precisely to the landing;.secondly, it

serves` as an indicator to the passengers lentering orleaving-the car that the car is at the landing and hence in position for transfer'of passengers; and thirdly, the light is thrown or.flashed`just where it is needed t0 ienable the p assengers to pass-,the doorway in complete safety or without stumbling or,

groping.

'In order to-eflect `the foregoing advantages Ilind it essential or desirable for the vario-us times to suit itI to the various types of cars which may be equippedtherewith,

the variety of typeshavin'g reference to differences of speed and to the space intervals which must be observed'. between the time of movement of the operating lever toveffect the stopping of the car andthe time of actual f stopping. More specifically, in the stopping of a high speedcar the operating lever must f be moved towardV stoppingv position at a.

greater distance from the landing than in a slow speed car. It is therefore important or normal position.v In-,other words, `the oper-` Vcar. f v

The circuit injthis preferred form ofthe invention, therefore, includes a pair of desirable that the switches or contacts which initiate the illumination'shall be made operative nearer the fin'al position of the ope'rating lever than inthe ca'se of a slow speed switchesor circuit breakers l'18 and 19 arranged on o-pposite sidesxof the operating lever when in mid position and adjustable toward 'or fromsaid operating lever in accordance with theV varying conditions above referred to. The location or adjustment of the switches, it'willl be understood, is inde-' pendent of the extent of movement of the operating lever in either direction from its ating lever is adapted to pass either of the iswitches when Qstarting the car, and after the operating lever passes the switches on movement to running position, therewill be- --no ccperation between the operating lever and the switches or any part of the circuit until the operatingvlever is started back and -approaches its mid position'again.

, The casing 15 is supported upon a pedestal 20 secured preferably upon the floor 2l of the car, though as to 'the particular l. means for securing the pedestal in place I do not wish to be limited. TheA means shown, however, is reliable and satisfactory.

rcuit 17 to be completed or broken at Thecasing is substantially rectangular in form and of.cons1derable height in compari- `son with its cross sectional area. The'pedestal 20 is-hollow and the circuit wires are led upwardly therethrough andthe circuit within the casing includes not only the la'mps 16 but also preferably a key switch 22l whereby the lampsmay'be extinguished when thecar. is 1left standing for any length i, of time. .The front of the casing consists of a removable plate 23, that portion of which is in front of the lamp comprises a series of transverse, parallel, downwardly inclined shutters or bailes 24 mounted in fixed posiytion at the sides of said casing. lAs shown 1n Figs. 1 and-8, said baflles are so arrangedv as to concentrate thegrays of light Aupon the threshold of the carfand the landing, and

they prevent, there-fore, any blinding effect ofthe intense light from `within the casing interfering with the expeditious transfer of the passengers. Said plate 23 is removably secured tothe front of thecasing by means of screws 25 whereby easy access may beK had to the lamps when -necessary for' inspectlon orl repai1",a'nd at the lower end of the casing is provided an openable cover 26 Y givingaccessA to the ley switcl`1-22 The 4lamps 16 may be of. any Awell known construction and each is seated in its own'socket -1-6" shown as secured in-the end of a reof one of them, therefore,`will beunderstood as being applicable to both KEach switch device in its preferred form comprises. a casing 28 adjustably related -to` the path of movement of the controller and secured in any desired-position with respect to distance from the normal position of the operating lever by any suitable means as, for instance, by clamping or binding screws 2,9 operating through the rear wall of the casing 28.' The switch proper, indicated at.30 is pivoted on a stud 31 fixedto said rearwall, said switch being adapted to oscillate in a plane subs tantially parallel to the vplane of movement of the operating lever. The -switch 30 includesA a main body portion having a pair oflaterally divergent depending portions 32 and 32', and secured to. said body-or extending upwardly therefrom o'n'the oppositeside of the pivot 31 from said depending portions is a stem 33 which carriesa peculiar bridge piece t'insulated, however, from the stem .and body by a spool-shaped insulating member `rlie members 34 and 35 are secured in place'on the stem by .means of a portions-32 of the two switches both extend on theJl operatinglever.

roperating lever is moved to start the car, it

weier screw 36 tapped into'the upper end of the vstemand a fiber Washer 37 completes the insulation between the bridge member 34: and the stem. vCircuit wires lead int'o the casing preferably from the rear through a fiber vbushing 38 and are respectively'connected to contact springs 39 and 39 with which the bridge member makes direct contact.

rlheoperating lever is provided with a pin or projection 40.-which,' while passing either switch casing, is adapted to cause oscillation of the switch by contact with one or the other'of thel depending portions 32, 32,

and therefore the operating lever will cause the switch either to make' or, break the circuit' at such;point. l With referencenowfto Figs. 2 and 3, it will be observed that when the operatinglever is ,in mid position or, at any point between the two switches, both switches will be closed and the lamps burning. In such position the two-'depending within the 'range of the projection or' pin Li0 Hence, when the will have passed `onits way a comparatively7 shortvdistance until the pin 4:0 strikes one or the other of the depending portions 32 caus ing the switch on'that side to be thrown out of engagement with the contacts 39 and 39', 'i

breaking the circuit 17 andextinguishing the light. The other switch, however, remains in closed position. ln other words, the arrangement 'is 'that at least one of the two switches is always closed.' On the returnof the operating lever to Stopping position, the'pin 40 will engage the depending. portion 32 of the switch last operated upon thereby, causing the switch to become closed,v

re'lghting the lamps. The insidefof each switch casing is preferablyliiied' throughout with. insulating fiber as shown at 4-1, and the lid 28 of such casing is secured in place by means of a lip 28a which hooks'over a fixed stud 42 at oneend, the. other end of the lid being secured preferably to the pivoty stud 31 by means of a single screw 43. Said lidalso is ,preferably provided. with lateral flanges 44 to assist in holding it in place. The construction of the depending portions 32 and 32 of the oscillatingswitches 30 and their relation to th'ejpinf() on the operating lever vare such that should either ofthe switches be tamperedl with'- malicously or otherwise, causing it to swing on its pivotv to the ,position opposite from which the controller may have left it, noyvda-mage will result. i In other words, it will be noted that each of the depending .portions is provided with yan inclined wall 32a on the outside or ,-theside remote from the-pivot 31, the effect of which is, for instance, if the operating lever shouldbe moved beyond a switch as shown at the right of Fig. 3, and before' the operating lever is returned toward stopping position some one should maliciously or inadvertently strike the lowermostdepending portion so as to cause the switchto bridge the contacts and cause the depending portion 32 to be de' pressed, the operating lever on making its next trip will simply ride against the wall 32 of the depending portion 32, Athrowing the switch momentarily out of contact. rlhe operating lever passing, however, in the same direction, will almost immediately thereafter cause the resetting of th-e switch for operation in accordance with the invention.

Having thus described my invention, li
