Tb all whom if ma?) Be it'- known that we, BYRON E. Miinwin andl EDWARD P. Dom, citizens of the'4 United States, residing at Wheaton, iii the county of Dupage and State of Illinois, havel invented new and useful Improvements in Safety Train-0rder Holders, of which the following is a full, clear, concise, and exact description, reference ,being had `to the accompanying drawing, forming a part of this specification.'

Our invention comprises certain new and useful improvements in safety train order holders, and has for its object the' production of a' device by means of which the orders received by an engineer or motorman on an electric car may be kept constantly before him and in such condition that the said engineer or motormanmay at all times be reminded of the fact that there are... unexecuted orders before him. A

A further object is the production of' a device in which the electric .current is utilized to illuminate -the order and at the same time give a visual signal to the operator 'that there is an order to be executed.

A further object is the production vof a device in which the operator is kept advised by visual and audible signals that an unexecuted train order is before him.`

A furtherobject 'is the production of a simple and ecient device that can be placed within the cab or car, that will utilize little space, that is of simple construction, and not liable to get out of order.

These, and such other objects as may hereinafter appear, are attained by our device, an embodiment of which is illustrated in the accompanying drawing, in which- Figure 1 represents a-perspective view of our device in position within a cab or ear; Fig. 2 represents a sectional View on the line 2 2 of Fig. 1, looking in the direction indicated by the arrows; and Fig. 3 represents a sectional view on the line 3---3v of Fig. 2, loolring in the direction indicated by the arrows. d

Like numerals of reference indicate like parts in the several gures of the drawing. Referring now to the drawing, Ltre esents a plate or holder, preferably of s eet metal, turned inwardly at the top forming a flange 5. The device is secured in place against the walls of the cab or car by 'means of screws or fasteners passing through openings 6 in the body of the plate or in any as shown at 27 to other. desired manner.' a wire @up 7' is secured at the'top and designed to hold the order or' orders S- flat against `the fue, of

.the plate. 4. At the center of the -lz'inge'A or 60 shoulder 5, a portion 9 is cut away and extended upwardly in line with ,the body of the plate, and to this is secured a hollowv light containing casin' 10, preferably by means of screws 11 vpas ng through the up- 65 wardly projecting ear' 9 into the wall of the casing. The casing 10 maybe a brass casingl or otherwise constructed and i's of any desired 'shapebut is provided with a circular opening 12, within Vwhich is fitted an incandescent lamp socket- -13v preferably of porcelain, and of any standard construction. 0n the interior of the casing is preferably provided an annular-'flange 14, and the porcelainsocket '13 has anenlarged peripheral 75 portion 15 adapted to rest upon the shoulder formed by the top of the flange 14. A screw or pin 16 extends' through the top of the casing and strikes the top shoulder 17 ofthe enlarged portion 15, thereby securing the so socket within the casing. y A lamp 18 preferably of about two candlel power is screwed into thebase of the socket,

and conducting wires 19 connect the lamp in circuiti. An opening 2O is formed in the 85 outer face of the lower portion of the casing opposite the lamp 18% and a lens 21 is fitted therein, formed preferably from .red glass.. `Wires 22 extending' from the connecting wires 19, connect a small buzzer or annunci- 9o ator 23 in shunt with the lamp 18. This is preferably placed at the back of thepplate and secured thereon in any well knownmanner, as by screws 24. A cover. plate 25 is pivotally mounted on the base of the casing by ymeans of a pivot 26 and-one corner of this plate is preferably turned downwardly,

permit the operator to engage and swing theplate about the ivot y 26, thus preventing the light from the amp A 18 from shining through the bottom of the casing in the event that the operator does not require the same. The current, by means of which the lamp and 'buzzer are actuated, is controlled by an ordinary snapl switch 28, located in any convenient position with reference to the device and coveredv by an ordinary cover 29.

Referring now to the operation of our device, let us supposethe device is permanently installed within the cab of a motorman or engineer. A train order is handed Ito the operator at once placed on the holding plate 4 and held-thereon. by means of the spring clip 7 At the same timethe switch 1s turned, throwing'the current on vand lighting the lamp 18. Byjthrowing the shield toA one'side, the light shines down on the order, maln'ng it a very sim le mat- 'ter to read the same. Not only is t e light directed downwardly by the casing, but the ange 5 serves as a reflector for this purpose. W'hile the lampj18 is small enough Y and the direction of its rays suiciently confined' not to light up the cab as a whole, it

the motorman. At the same time, the red light shines through the lens 21, and While unexecuted order on the holder.

guishinv 'removed l fact that there is no re not strong enough to light up the cab or to irritate the eyes of the motorman, it serves .as a reminder of thepresence of the order.

If, for any reason, the operator does not care -to read the order atonce, or if from the circumstance's of the case the same is 'not to be executed for some time and it is desired to shut out all extra light within the cab or car, the shield 25 is turned into positiomas lshown in Fig. 1, shut off entirely the light from the bottom of t e casing, leaving the order in darkness. At the same time, however, the light shines through the red lens 21. As this, however, is very small and plreferably of thick glass, the light there--w om is very slight, serving sim ly as -an indication to the operator that t ere is an As the time approaches for the carrying of the order into effect, or any portion of'it', the operator simply has to place his thumb or .finger on the corner ofthe shield 25 and that operates while the current is on. This buzzer or annunciator may be of any desired character so that the intensity of. sound may be regulated to suit the Wishes of the o erator. Ordinarily, it should produce o a low` buzzing sound. In any event, if 1t be used, an audible sound of some kind is kept up during the entire time that the current is on and an unexecuted order remains on the order holder. Wel have thus provided a simple and eilicient Imeans vwhereby the operator is furnished` with a visual and, if desired, an audible and visual reminder of the fact that he vhas orders to execute, and such reminder is always before him until such order is fully executed. v

While we have shown certain methods of \Inechanica1 and electrical construction, 'it is to be .understood that we do not limit ourselves to such process and construction, but any equivalent means by which an operator within the cab or car lis kept advised of an iunexecuted train order comes within the scope of our invention.A We claim:

In'a train order holder, the combination 'wlth a supporting plate constructed to be conveniently attached to a wall or other support and affordingl a supporting back for a train,order sheet, of a spring clamp on said plate to clamp and hold the train order in osition thereon and to permit the same to readily removed from said plate or placed thereon, an electric` lamp socket, at

ceive an electric lamp bulb and having a casing surroundin the bulb, the lower end of said casing having an opening therein to permit -the light td shine directly upon the face ofsaid board to illuminate the train order and permit it to be readily seen, -a shutter` for said opening to enable the light to be shut off from the face of said board when desired and without turning out the light, a second opening in the front of said casing, a colored glass or equivalentlling for said opening to cause the light shining therefrom to give a .distinctive visual signal to advise the operator of the presence of an order on the said board.

In witness whereof, we have hereunto subscribed our names in the presence of two witnesses.
