Jrfn IOnyu/afi ATTOR YS United States Patent 3,ll75,l7d Pt) \TAB' E BLWKING WARNING SlGN AND CGNTRGL HANDLE .sohn .l. Grszulak, 6 Pine Lake Ave, La Porte, Ind. Filed done 14, N61, Ser. No. 117,136 2 Claims. (Cl. Sell-N7) The present invention relates to a safety sign for school patrols and guides at street crossings, for railroad use, or the like, and more particularly to a safety sign which may be illuminated selectively in accordance with its position.

The present invention provides a safety sign which is exceptionally simple and may be illuminated as desired by raising the sign, without the need for manipulation of a switch or the like. Accordingly, the sign of the invention is especially adapted for use by young people patrolling a crossing or the like, as well as by those whose attention is otherwise fully occupied, as for example, in railroad operations.

In accordance with the invention, a sign adapted to be illuminated from within is mounted on a handle in which batteries are slidably mounted for selective engagement with a contact element on a cap or the like removably connected to the bottom of the handle. At the top of the handle, a metal weight or the like is positioned for contact with the top terminal of the batteries and carries a metal stern having a socket in which is threaded a bulb, preferably of the blinker type. The sign thus houses the light and has formed therein transparent or translucent indicia or letters ior contrast and signal effect when the light is energized. For example, the word Stop may be formed on opposite sides of the sign and the sides themselves may be or" an opaque colored plastic, cut-out metal or other material, connect d by suitable means to the handle so as to permit the stem to move therein as carried by the Weight referred to.

A circuit for energizing the light is provided by a lead wire extending from the socket through the. stem and past the weight and batteries in the handle to the contact on the bottom cap for the handle, with the lead wire affording a predetermined relative movement for the stem. The batteries and weight are retained in the handle by suitable end wall or stop means at the upper end of the handle and together have a length somewhat less than the inner length of the handle. Thereby, when the handle and sign are lowered to a downwardly inclined angle, the batteries and the weight will slide away from the bottom contact on the cap for the handle, to deenergize the light. Conversely, when the handle-and the sign are raised, the lowermost battery will engage the contact to energize the light and afford a blinking signal by the illumination of the translucent or transparent indicia on the side walls of the sign.

Accordingly, it is an object of the present invention to provide a gravity operated signal of exceptionally simple construction.

Another object of the invention is to provide a sign as described which may be selectively illuminated by changing the position of the sign.

Other objects and advantages of the invention will become apparent as the description proceeds in accordance with the drawings in which:

FIGURE- 1 is a front elevational view of a sign and signal device according to the present invention;

FIGURE 2 is a vertical sectional view taken along the lines II-II'of FIGURE 1; and

FIGURE 3 is a vertical sectional view, partly broken away, and showing the sign and signal device in a deenergized position. 1

Referring now to the drawings, a safety sign it is ice shown according to the present invention which includes an upper sign structure 12, a lower handle 14- supporting the sign structure 12, a light 16 positioned by a stem it; within the sign structure 12 and one or more batteries, indicated by reference numerals 2t}, 22 and 2 for selectively energizing the light 16, as hereinafter further described.

Further in accordance with the invention, the stem 18 is mounted on a weight or other support element 26 within the handle 14 and the stem 18 receives an insulated electrically conductive wire 28 soldered or otherwise secured to a contact 29 on a socket 3d at the upper end of the stem and extending loosely around the weight 26 and the batteries 2i; through 24 into electrical connection with a contact 32 at the bottom of the handle 14. The contact 32 may be of any suitable conductive material soldered or otherwise engaged on a cap 33 releasably threaded on the lower end of the handle 14, as understood by those skilled in the art.

Accordingly, an exceptionally simple gravity operated signal means is afforded such that when the handle 14 is inclined downwardly so that the contact 32 is elevated somewhat above the weight 26, the batteries 2d through 24 will move away from the said contact with a sliding action to break the circuit between the batteries, the metal weight 26, the stern and the light 16 and the line 28 joining the contact 29 and the contact Conversely, when the handle 14- is moved angularly upwardly, the batteries as through 24 as well as the weight as will slide downwardly so that the lowermost battery 29 will again contact the contact 32 to complete the circuit and energize the light in.

Desirably, the light 16 is a blinker light of any suitable type so that by the simple angular movement of the handle described a blinking signal will be provided which is exceptionally efiective to alert pedestrians or other individuals at locations such as street crossings, railroad crossings or other intersections or locations.

The sign structure 712 preferably includes a pair of side walls 34 and 36 which may be formed of plastic, metal or any other suitable material and may be dished convexly to form peripheral edges which register in abutting relation and may be joined by thermosetting of the plastic, heat treatment of the metal or by means of lugs or tabs or the like as understood by those skilled in the art. Preferably, each of the sides 34 and 36 is opaque for the major extent of its surface but defines indicia or lettering of translucent or transparent characteristic. Such lettering may for example be provided by stamping or cutting out the material of the sides so that an open space is atforded of the desired type, although where plastic sides are utilized the material itself may be rendered transparcut or translucent in the area of the indicia. And the sides may be generally light permeable if desired. In the example shown, the word Stop is formed on each side of the sign structure 12:, in general registration with the bulb it? so that when the device is energized a blinking light si nal will r diate through the individual letters on the opposite sides of the sign thereby conveying a clear warning and direction to cars, pedestrians or other persons, in accordance with the specific situation in which the sign is utilized.

The sign structure 12; in the example shown is of an octagonal configuration in front elevation, since this particular configuration in itself conveys a message to the observer. However, it will be understoodthat a variety of configurations and shapes maybe providedrto meet particular conditions. 7 v

in order to connect the sign structure 12 with the handle 14, the sign itself may be cut away at a relatively wide edge portion 38 to form a substantially rectangular deenergization of the light. slidable movement may also be adjusted by rotation of recess of somewhat reduced dimension relative to the width of the handle 14 and the handle 14 may be cut away to form a slot structure 41 at its upper end so as to snugly receive and engage the sign adjacent the edge 38. A suitable cement or other such adhesive material may be disposed around the boundary portions of the slit or cut 40 and the adjacent areas of the sides 34 and 36. It will be noted that the side 38 is relatively wide at its edge so as to provide a suitable stop for the hand gripping the handle 14; However, a variety of constructions may be accommodated within thescope of the invention in this respect and in respect to the mode of connecting the sign structure 12 to the handle 14.

Since the handle 14 at its upper end is cut away, as indicated, the stem 18 may extend readily upwardly therethroughand into the inner area 42; formed by the sides 34 and 36; and while this extension of the stem 18 under the sign is unobstructed as described, the weight 26 itself is preferably of a sufiicient .width to engage upper end flanges 44- and 46 for the handle 14. Thus. theseend 32 axially to the stops 44 and .6 need be only slightly greater than the combined dimensions axially ofthe weight 26 and the batteries 20 through 24.. Thus any slight amount of spacing afforded by the downward move- -ment of the batteries and the weight will suifice to disengage the lowermost battery 29 from the contact 32 and to deenergize the light 16. A relatively small extent of .slidable movement for the batteries and the-weight is in general desirable, Since this arrangement aifordsa high degree of responsiveness to upward and downward movement of the handle and sign for prompt energization and The spacing and extent of the cap 34, as by a screw means or the like, or is mounted on the side of the handle t) itself adjacent the outerend thereof. Thus the device may hang freely in depending relation from the belt when not in use but may be removed quickly for action as needed.

The lead wire or line 23 may extend outwardly from the bottom of the stem 18 through a bore 54 in the weight 26, although any suitable construction may be utilized so that there is no substantial possibility of the line 23 interfering with the slidable action of the parts within the handle, and, e.g., the line may be attached in insulated relation to the weight at the lower edge of the weight.

Although the invention has been described with respect to the use of a metal weight as indicated at 26 so that the connection or circuit for the light 16 may be positively and gravitationally closed when the handle is raised, it will beappreciated that the stem itself could extend downwardly into contact with the upper terminal 56 of the uppermost battery 2-4. In such a construction, it would in general be desirable to have a sliding fit between the upper end of the handle and the stem for guidance purposes, and it will further be appreciated that various alternative mountings for the stem may be afforded such as a thin disk secured to the end of the stem 18, with the case itself being dimensioned conformably to afford the desired spacing for slidable movement of the batteries as described above.

Accordingly,.there has been provided a gravity operated signal and safety sign which is rugged, attractive and simple in construction and is adapted for use in a wide variety of situations. The elimination of manual direct traffic atpatrolled crossings or the like for schools and also to meet conditions where full attention must be given to railroad crossings or operations in a railroad yard, or wherever safety and signal signs are commonly used.
