JESSE L. MAYBERRY, OF NEW YORK, N. Y.

SIGNALIN G ArrAaA'rUs.

To all whom it may concern:

Be it known that I, Jnssn L. MAYBERRY, a citizen of the United States, and a resident of the city, county, and State of New York, have invented a certain new and useful Iniprovement in Signaling Apparatus, of which the following is a full. clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

This invention relates to improvements in signaling apparatus which comprises movable indicators so arranged and capable of being so operated as to enable the driver of an automobile to show by them. when he intends to turn to the right or left or to stop, the object of the invention being to render apparatus embodying it better in its mode of operation and less apt to require objectionable care than any similar apparatus heretofore devised. The invention consists of signaling apparatus having the features of construction, the electrical and mechanical parts, and the combinations of devices, which are described below and specified in the claims.

On the accompanying sheets of drawings, on whichlike reference-numorals designate like parts of different views:

' l igure 1 is both a front elevation of parts of apparatus embodying the invention, and a. diagrammatic illustration of electrical circuits and switches on which the operation of the appa atus depends.

F 2, a detail of a crank-arm, partly shown in Fig. 1;

Fig. 3, a plan of three eleotromagnets and other devices which the apparatus includes, two of these magnets being solenoidal magnets; 1

Fig. 4-, an enlarged sectional view of one of the solenodial magnets;

Fig. 5, a front elevation of the multiple switch diagrannnatically illustrated in Fig. 1, the switch being in'a case which is shown in section; and

Fig. 6, a top view handle of the switch.

The indicators, magnets, and soinoother parts of the apparatus are supported by an oblong frame which is to be aflixed to the back of an automobile and inclosed in a case, having openings so formed and arranged as to enable the indicators to ,m ove from their normal positions to others in which they will pro ect from the'endsof the case.

of this case and the Specification of Letters Patent. -Patented Sept, 1 1918, Application filed November 30, 1915. Serial No. 64,239.

The frame is composed of the'front and back plates, 1 and 2, and the cross-bars 3. The shafts, 4 and 5, which are rock-shafts, extend through these plates and have bearings in blocks fast on the inner faces of the plates. The indicators 6 and 7 are fast on the shafts l and 5 respectively at their rear ends. These indicators are preferably arrows, each having the form of the arrow 6 (Figs. 1 and 3), one of them (6) having on its back the word Right, and the other (7) the word Left. The shaft 5 is tubular and through it extends the small shaft 8, to which is affixed at its rear end the indicator -9, which is an oblong plate a little wider and longer than the arrow '1 and on the back of which is the word Stop. The shafts 5 and 8, which have a common axis, are normally clutched together by means of the disk 10 and latch 11, the disk being fast on the shaft 5 at its front end and ,the'latch surrounding the shaft 8 and being pivoted thereto by pins 12, and having on it at its inner end (the end toward the right of the automobile) a stud 13 which fits in a hole in the disk, the spring 14 tending to keep the latch engaged with the disk. The latch extends outward beyondthe disk and has at its outer end the eye 15. The crankarms 16 and 17 are fast on the shafts 4c'and 5 respectively and when the indicators are intheir normal positions these crankarms extend straight upward from the shafts. Each crankarn'i hasin it, at its swinging end, a short slot 78 (Fig. 2).

'lhesolenodial magnets 18 and 19 are pivoted to and'between the plates '1 and 2 of theframe, the pivots of the magnet 18 being at the pointsQO and those ofthe magnet 19 at the points 21. The cores 22 and 28 of these magnets are connected to the crankarms 16 and 17 respectively by the pins 24 and 25 which are tight in the cores, extend through the slots 78, and fit loosely in the slots. The coilsprings 26 and 27. surround the cores and bear against the spools of the magnets and against disks on the cores, and exert on the crankarms through the cores .force enough to hold the arrows 6 and 7 and the sign 9 in their normal positions.

The 'core'of each or tllGSGii'iitglletSClOSGlY fits in a non-magnetic tube 28 which may be brass and/in which the core acts as does apiston in its cylinder, the tube having the head 29 and the core having in it a nonmagnetic plug 30 projecting from its end and forming a-stop to limit the inward movement of the core. In the head 29 are two small apertures. One of these is partly closed by a screw 31, in the stem of which is a groove extending from the head throughout the length of the stem. By this means a vent is provided, the size of which may be varied by turning the screw from its outer end. In the other aperture is a ball 32 which fits against a valve-seat between it and the inner face of the head 29, the ball being loose in the head and being confined between the seat and a pin fixed in the head and extending across the aperture.

The spool of the magnet 33 is attached at its ends to the plates 1 and 2. The core 34 of this magnet passes through the plate 1 and has at its front end a pin 35 formed on or fast in the core, and when the latch 11 is in its normal position the front end of this pin is close to but a little behind the eye 15 of the latch.

The brackets 36 and 37, attached to the front face of the frameplate 1, support two groups of devices which form parts of the electrical circuits and some or all of which are fiat springs. The three devices 38, 39 and 40 are fastened by screws to the top of the bracket 36, and each is insulated from the next and from the bracket and screws by non-conducting material represented in Fig. 1 by heavy black lines. The device 40, which is a spring, is normally in contact with a projection on the device 39 near its right end. The latter device may or may not be a spring. To the device 38, which also is a spring, is attached the bar 41 which projects over the shaft 4: and on the under side of this bar is the block 42, the lower face of which is inclined as shown. The pin 43, which is afiixed to this bar under the right end of the spring 40, is normally out of contact with the spring but is movable into contact with it by the act-ion on the block 42 as hereinafter described of the pin or cam 44 fast on the shaft 4.-. The devices 45, 46

' and 47 on the bracket 37 are similar to those on the other bracket, each of these being insulated from the others and from the bracket and the screws which attach them to it. The bar 48 is fastened to the spring 45, from which it extends over the shaft 5, and on the under side of this bar is a block similar to the block 42, and in the bar is a pin the relation of which to the spring 47 is similar to that of the pin 43 to the spring 40. The pin 19 fixed in the disk 10 and projecting from the back thereof under the block on the bar 48 acts on this block in the operation of the apparatus as hereinafter described.

The case 50 incloses the parts of the apparatus which are supported by the frame, eX- cept that in the under side and ends of the case are slots 51 through which the arrows and sign 6, 7 and 9 are movable to positions in which they project from the ends of the case, as described below. The bands 52, attached to the plate 2 and to the rear wall of the case and extending over the indicators, andthe band 53 attached to the plate 1 and front wall of the case, hold the frame and case together. On the case are mounted the tail-lamp 54: and the right and left signal-lamps 55 and 56.

The multiple switch comprises a block 57 (Fig. 5) of insulating material supporting four groups of spring-contacts. The standard-58, resting on and fastened to this block, has at its upper end the ball 59 (indicated by dotted lines) which fits in a socket in the under side of the four-armed spider 60, having the stem 61 which extends through the top of the case and has at its upper end the handle 62. The top of the switch-case 63 has in it the opening 64, in the four branches of which the upper part of the stem 61 is movable from its normal position to the right, to the left, forward, and back ward. The opening 6st is covered by the shield 65, attached to and movable with the stem 61. The arms of the spider, which is of insulating material, extend to the four groups of spring-contacts, one of these being on the right of the standard 58, another on the left thereof, another in front of it, and the other behind it, and each group comprises two springs 66 between which an arm of the spider extends and which so bear on the arm that when its outer end is raised the upper ends of the springs are forced outward. The springs 66 of each group are normally in contact with the springs 67 thereof, and will be forced out of contact with the latter when the handle 62 is moved and the spider so rocked on the standard that the outer end of the arm extendin betweenthe springs 66 is raised. The right, left and front groups are all alike, and each of these groups comprises springs 68 which are normally not in contact with the springs 66. The springs 66 of each of these groups are forced into contact with the springs 68 of the group by the action of the spider when it forces the springs 66 from the springs 67.

he rear group does not include springs 68.

In the diagram of Fig. l the circle 69 represents the spider and the lines 70 repre sent the springs 66, other lines representing the other springs of the four groups, as will readily be understood. The wires of the circuits which include the battery 71, and the right, front and left groups of springs of the multiple switch, are shown connected to posts A B C D E F G H, and to posts a b 0 (Z 6 f, some of the wires being also connected to the devices 38, 39, 40, and 45, 46, 47. The circuits which include the windings of the solenoidal magnets pass through the pivots of these magnets. The winding of the magnet 33 is connected to the spring $7 at its right end and to the post H. The rear group of springs of the multiple switch is normally in the circuit which includes the head-lamps 7 3, battery 74, and switch 75, and parts of which are'connected to the resistance-coil 76. The length and height of the case 50, and those of a common llcense-plate, are about the same respectively, so that the licenseplate 77, which will cover or nearly cover the back of the case, may be attached thereto. Apparatus like that contained in the case 50, but preferably not includinga stop-signal (9) shaft 8, clutch, or magnet such as the magnet 33, for these would be unnecessary and therefore not desirable, may be attached to the front of the automobile and inclosed in a similar case, and on the front of the case may be two signal-lamps like the lamps 55 and 56. The front solenoids and lamps (not shown) would be connected with I the posts a, b, 0, the, f, as the solenoids=18 and 19 and lamps 55 and 56 are connected with the posts A, B, C, D, E, F. 7 The switch72 is in the circuit which includes the tail-lamp 54, and to this switch extend wires le'adin from the other four lamps. At those pomts close to the switch where the five wires leading from the tail- ]amp and four signal-lamps end, there are five contacts all of which are broken when the switch isopen. This switch is to be closed only when the lights are needed. When it is open current does not pass through any of the lamps. When it is closed current passes constantly'through the tail lamp 54:, going to the'lamp from the battery 71 through wires (1 and (f, the post G, and wire a and going to the battery from the lamp through wire aflthc' switch 72, and wires a and a 'butcurrent does not pass through either of'the signal lamps 55 and 56 unless the multiple switch is operated. When the handle 62 of the multiple switch is swung so that the spider acts on the springs 0 of group I, hown at the left of the circle 69 (Fig. 1), and forces these springs into; contact with the outermost springs of the group, current goes from the battery 71 through wire a to and over'two springs of group II, and thence through wire a to group I where, if the apparatus includes frontas well as rear signals, it divides into two branches, and these branches go over springs of group and b, passing through wires a and a"respectively. From post B current goes through wire a, plate 39, plate l0, wire a, the solenoid 18, wires a and a, post D,and wire a, to the battery. I From post 6 current goes through wire a, plates (not shown) similar to 39 and 40, through the front right solenoid,'and wire a, to post (1, and thence to the battery through wires a a and a. If the apparatusdoes not include front signals then the current goes from" group I to reaches the plane containing a shaft 4: and the pivotal axis of the solenoid,

I and to postsB post B and thence through the solenoid 18 as described, but of course will not go to post has this will not then be in a circuit.

the switch 72 is closed, a branch of the current goes from post 13' through wire a, to and through lamp 55,:through wire a, to post A, through wire a to switch 72, and thence to the battery through wires a and a, and if there is a front right signal-lamp a branch of the current goes from I) through wire a, to and through that lamp, through wire a, to post a, through wire a, to switch 7 2, and thence to the battery through wires a and a. Current will notthen pass through any of the other magnets or any of' the other-signal-lamps. V

The magnet18, thus energized, pulls the crank arm 16 to a horizontal position, and swings the arrow 6 on the axis of the shaft 4: as indicated by Fig.1, which shows this crank arm, the solenoid and arrow just after the action begins and when the arrow has left its normal position in the case 50. When the-pin 24, which connects the core of the solenoid to the crank arm, reaches or nearly the axis of the the projection 44 acts on the block 4L2, forcing the pin 43 raising its right end, so that the circuit is broken between the, plates 39 and 40. The bar 1-1, which is connected with the post C by wire a, is not then connected with the battery because the wire a leading from that post to the multiple switch is connected to the spring which is next to and in front of the rear. spring 70 of group I'and these springs are not then in contact, so-that, although springs 70 of groupI are connected with the battery, current cannot pass to wire a through'springs of that group. As the circuit passing through the solenoid is thus broken, the spring solenoid outward, the momentum of the arrow 6 and other parts continuing the movement of the crank-arm 16 while the pin 24. is moving from end to end of the slot 78 in the 'crank'a-rm and passing from sidcto side of the aforesaidplane, and the movement of the arrow is continued by the action of the spring 26*un'til the arrow'extends horizontally outward from the end of the case 50, and there it will be held by the spring until the handle of the multiple switch 'is'again moved. The arrow, pointing to the right, and having on the back the word Right, lainlyf visible from behind either in, daylight or the light thrown on it by the lamp 55 at night, indicates an intention of the'driver of the automobileto turn against the spring 40 and 26 forces the core of the is restored to its normal position, current goes from battery 71 to group .II, thence to group I, and thence to post G through wire and a branch goes to post 0 through wire a if there are also front signals, and from C current goes through wire a, to spring 38 and through this spring, bar 41, pin 43, spring 40, wire a, the solenoid 18, and wires o and a, to post D, and thence to the battery through wire a. Thereupon the lower end of the crankarm is drawn upward by the energized solenoid 18 until the pin 24 is between or nearly between the pivotal axis of'the solenoid and that of the crankarm and arrow, when the projection 44 leaves the block 42, and the spring 40 re turns to its normal position, again making contact with the plate 39. By this action the circuit broken. The momentum of the arrow and other parts continues the movement of the arrow until the pin 24reaches the inner end of the slot 78 in the crankarm and passes from between the pivotal axes of the solenoid and shaft 4, and then the spring 26 forces the arrow to its normalv position and there holds it. The circuit which includes the lamp 55 is broken when the handle of the multiple switch is restored to its normal position, for the springs of group I of that switch then move away from the front and rear springs of the group.

From the foregoing description it will be understood that when the handle of the mul tiple switch is moved so as to force outward the springs 70 of group. I, a front right solenoid (not shown) would be energized as.

is the solenoid 18, and a front right arrow or similar indicator (not shown) would be thrown out as isthe arrow 6, and current would pass through a front right signallamp (not shown), that when the handle is restored to its normal posit-ion the solenoid would be energized, the arrow would be returned to within the case, and the circuit in cluding the lamp would be broken, and that during the outward movement of the arrow, and during its return, the circuit in cluding the solenoid would be broken by the action on it of the solenoid, and the spring surrounding the core of the solenoid enabled to continue and complete the move ment of the arrow. The front solenoid will be energized to impart the inward movement to the arrow, by current passing from post 0 to the batterythrough wire a, devices like spring38, bar 41, 7 above described, and through the solenoid, wire (1, post (Z, and wires a1, a and a.

A movement of the. handle of the multiple switch so that the springs 70 of group III will be forced into contact with the front and rear springs of the group,will enable current to pass from the battery 71 through wire a toand over two of the sp ings of passing through the solenoid is pin 43, and spring 40,-

group II, through wire (6 to springs 70 of group III, and thence, if there is a front left signal (not shown), over the front and rear springs of group III, and to. posts F and fthrough wires a and a respectively. From post F a branch of the current will go through wire a, to lamp 56, through wire a, to and over switch 72, and thence to the battery through wires a and a". Another branch, starting at post F, will go through wire a, plates 46 and 47, wires a and a the solenoid 19, wiresai anda, and to post D, from which it will go to the battery through wire a, and another branch, starting near the spring or plate 47, will go through wire al the magnet 33, wire a, to post H, thence through wire a, to and over two springs of group II, and thence to the battery through wires a" and a. Hence the battery will then energize both the solenoid 19 and the magnet 33, and will light the lamp 56. .The magnet 33 will. draw backward the eye of the latch 11 so that the latch will be disengaged from the disk 10 and the eye will surround the pin 35 on the core of the magnet, and then the shaft 8 will be locked to the magnet and be prevented by the latter and the latch from turning. By this means the sign 9 will be held in its normal position during the action of the solenoid 19. The solenoid will draw the crankarm 17 to about a horizontal position, the circuit including the solenoid will be broken by the action of pin' 49 on the block attached to the under side ofbar 48, and by the action on the spring47of the upwardly projecting pin on the bar 48, and the spring 27 will act on the crankarm and continue and complete its'movement. The breaking of the circuit in this operation during the outward movement of the arrow 7, denergizes the magnet 33 as well as the solenoid but the latch will be kept engaged with the pin 35 of the magnet by the action of the stud 13 on the front face of the disk.

The return of the handle of the switch to its normal position will enable current to go through wire a group II, wire a, group III, and wire a to the post E, then through wire a, spring 45, spring 47, and to the battery in two branches starting near spring 47 one going through wires (L38 and a the solenoid, wires a and a, post D and wire a, and the other going through wire a, magnet 33, wire a, post H,'wire a, group II, and wires or and a". Then the energized solenoid will draw the crank: arm-back to the horizontal position, the circuit willbe broken, and the spring 27 will complete the movement of the crankarm, shaft and arrow. As soon as they reach their normal positions the stud 13 of the latch 11 will be forcedby the spring 14 into the hole in the disk 10 so that the shafts 5 and Swill be clutched together again,

If the apparatus should include. a front left signal (not shown), but not a sign 9, the front solenoid would be energized in this Operation, first by current passing from post f through wire a to and through'the solenoid, through wire a, to post (i, and thence to the battery through wires a, a" and a", and afterward, to start the arrow'on its return (when the handle of the switch is thrown back to its normal position), by current passing through wire a group II, wire a, group III, wire a, post a, wire a, the front solenoid, wire a, 0st (1, and thence to the battery through wlres af, a and a. The action on the arrow by the solenoid and actuating spring, and the operation of the circuit-breaking means during the outward and inward movements of the arrow, will be such as have been described. The circuit including the front signal-lamp (not shown) will go from post 7 to the lamp, and thence to wire a, to switch 72, and to the battery.

When, with a movement of the handle of the multiple switch, the springs of group II are forced into contact with those at the sides of the group, current goes through wire a two springs of this group, wires a and a, to post F, to plate 4.6, to plate 47, to and through solenoid 19, to post I), and thence to the battery. If switch 7 2 is closed current also goes from post F through lamp 56. Current does not go through magnet 33 in this operation for the line leading from post I-I, wire a and springs of group II then ends in that spring of group II which is not connected at its lower end with any wire- The energized magnet 19, acting as described, turns both shaft 5 and shaft 8, then clutched together, and when the movement of the crankarm is completed by the action of the spring 27, both sign 9 and arrow 7 project from the end of the case, but only sign 9 can be seen frombehind for the arrow is hidden by it. The arrow and sign are moved back to their normal positions by the above-described action of the solenoid and spring 27 on the crankarm 17 when the handle of the multiple switch is restored to its normal position, and then the circuit which lights the lamp 56 is broken. In this operation current does not go to the front left solenoid or lamp.

The fourth movement of the handle of the multiple switch from its normal position breaks the circuit normally passing through group IV and the head-lamps 73, when switchis closed. By this means the current may be forced to traverse the resistancecoil 7 6 so as to diminish the lights of the lamps.

During the inward movement of the core of any of the solenoidal magnets, air is expelled from the tube 28 through the apertures in the head 29, and when the core is forced outward by the spring which acts The'size of the vent readily can be made such as to prevent the spring from acting too suddenly or forcibly on the crankarm and indicator or indicators connected therewith. I

But very little current is used at each operation of the apparatus, no matter how long a signal may be exposed, especially when current does not pass through any of the signal-lamps,and it is feasible to use in the apparatus described a current which would burn out or soon destroy a solenoidal magnet if it were to pass through itfor more than an instant.

- The multiple switch and circuit wires are preferably to be so arranged that when the handle is thrown car the right signals will be operated, when it is thrown toward the left of the car the thrown backward the stop-signal will be, operated, and when it is thrown forward the head-lights will be made dim. It will be understood that the invention may be embodied in apparatus differing more or less in formand details from that which has been described. v I Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: y I
