WRITING BOARD LAMP AND PAPER HOLDER Filed May 29, 1951 INVENTOR. 45 1? 6 MARSCHAT If! u HTTORIVEY Patented Nov. 10, 1953 UNITED STATES PATENT OFFICE 2,658,989 WRITING BoARn LAMP AND PAPER HOLDER Arthur G. Mars'chat, Whitestone, N. Y. Application May 29, 1951, Serial No. 228,799

3 Claims. 1 p

This invention relates to a writing board lamp.

It is an object of the invention to provide a lamp adapted for attachment to a writing board of a type such as used in taxicabs, delivery trucks and in like places where there is an urgent need at many times for a light to be available for writing on the board and whereby the operator does not need to bend or stretch to find adequate lighting for the board and can thus keep himself in an upright position to observe the road.

It is another object of the invention to provide a detachable lamp for a writing board which is so constructed as to contain a pencil and wherein the locating of the pencil in the attachment will automatically turn off the lamp and the removal of the pencil automatically turn on the lamp, in order to keep a pencil at all times available for the user of the writing board, the user of lamp thus being signaled whether or not the pencil is in or out of the lamp.

It is another object of the invention to provide in a lamp attachment for a writing board a simple means for the connection of the attachment to the Sides of the board that will permit the attachment to be turned up to release the paper but which, as the attachment is turned down, will retain the paper upon the board, this means of attachment being movable over center between its two positions with respect to theat taching arms that fix the attachment to the board. A

Other objects of the invention are to provide a writing board lamp which is of simple construction, inexpensive to manufacture, is formed of standard stock parts, has a minimum number of parts, and is compact, durable and eflicient in operation.

For other objects and a better understanding of the invention, referencemay be had thefollowing detailed description taken in connection with the accompanying drawing in which:

Fig. 1 is a perspective view of a writing board with the lamp embodying the features-of the present invention attached thereto and adjusted to retain the paper upon theboard.

Fig. 2 is an -enlarged longitudinal sectional view ofthe board and the attachment taken on line 2--2 of Fig. 1. V

Fig. 3 is an enlarged sectional view of the attachment and the board taken generally on line 3-3 of Fig. 2.

Fig. 4 is a bottom planned view of the attachment.

Fig. 5 is an illustrated viewshowing the manner in which the attachment is pivoted upwardly to release the paper from the board.

Fig. 6 is a fragmentary illustrated view on a large scale to'show the position of the attaching arms when the attachment is lifted to the position shown in Fig. 5 and showing the point which holds the paper elevated from the board.

Fig. 7 is a fragmentary View of a modified form of. the switch which may be used in the attachment and which is operated by a pencil.

Referring now to the figures, It represents a writing board adapted to receive a piece of paper I I upon which writing is to be made. The board ID affords a smooth top surface so that writing with a pencil I2 upon the paper I I will be effected in a smooth manner and without the paper being punctured by the pencil point.

According to the invention a lamp attachment indicated generally at I3 has been provided which can be secured to the top edge of the board If] by projections or arms extending over the sides of the board near the top edge thereof, and in such a manner that the lamp can be pivoted upe wardly to release the paper II or when pivoted downwardly onto the board itv serves to hold the the paper in a fixed manner thereupon. This same attachment I3 serves to support pencil I2 and this pencil may serve to operate a switch which will control the light bulb within the attachment.

The lampattachment comprises generally a main tube I4 formed of transparent plastic material, such as Lucite and a pencil tube I 5 adapted to receive the pencil, I2 and cemented orotherwise secured to the side ofthe lamp tube I I.

The lamp tube It has an end plug [6 which contains a lampsocket ll. Cable wires I8 extend through the plug I6, one of which connects with the lamp socket ll as indicated at 20, and the other of which connects with a sleeve contact as, indicated at 2i. This sleeve contact lies in the wall of the tube. A switch contact 22 is sidablethrough the; sleeve 2i, and when released by pencil E2, on the pencil IZ-being taken from tube l5,will engage the side of the socket I! so as to establish a circuit through the socket to light the. elongated lamp-bulb 23. j. The contact 1 2,2 is connected toa lever '24 pivoted at 25 to the.

interior of the tube I 5. A compression spring 26 urges the lever 24 upwardly at the end which is engagedby pencil I2 and downwardly at the con-' tact ends 22 whereby upon removing the pencil the contact 22 will be forced through the contact sleeve 2| and against the socket IT. The ends of the pencil tube I5 are cut away as indicated at 21 and 28 to provide easy access to the pencil so that it-can be easily pushed out of one end of the tube or the other.

In the opposite end of the lamp tube I4 is a plug 29 which carries an adjustable hook attaching arm or member 30. This attaching arm has a hook portion 34 which extends over the edge of the board In and engages with the underside thereof. A spring 35 is provided on the arm 30 to urge the hook portion 34 against the side edge of the board II]. An enlargement 35 is provided on the arm against which the vspringiii'l may react. It will thus be seen that the board can vary slightly in width and the attachment can be adapted to it. On the lamp plug end of the tube I4 is a fixed hook arm 31 which fit's over th'eSOpposite edge of the board It). Thecable wires 15 has a plug 39 thereon to fit the outlet socket or the vehicle and to establish an electric connection of the attachment with the vehicle battery.

There is a certain amount of give to the hook arm 30 and hook arm 3 to spring down the attachmentupon th board. Legs and 42 serve as a pivot' "on which the attachment can be retated upon the board is. The lowerends of the legs 4| are flat as indicated at 43, in-Fig. 16, was to stabilize the attachment when -in the raised position. The attaching arms 30 and 37 are shown tilted to hold the attachment flat upon the bottom faces 33 of the legs M and 42 when inthe raised position. As the attachment .is pivoted down on to the -boa'rd and into the position shown iiiFigs. 1 and 2, the projecting arms iii) and 3l'will :be tilted forwardly and paper engaging points 45 and 46 will be brought into engagement with the paper H. The spring arms 36 and 31 will forcibly hold the attachment in a position which is shown in Fig. 1 with the parts 65 and entering the paper) These arms will be in tilted position and the leg elements 4'! and '42 will be rolled on to theiriorward edges. If it is desired to release the paper, it is only necessary 'to lift theattachment in the manner as -shown in Fig. The points 45 and 46 thus are raised out of the paper. When the attachment is in the down position, as shown in Fig. 2, light rays will be projected toward the paper. The'o'paque-c'over ii'ig 41 extends over the greater portion of the tube 4. Since the tube is transparent, light rays pass through the uncovered portion thereof.

In Fig. '7 there is shown a modified --'forr'n of swi-tch w-herein contact terminals 48 and '43 are provided' respectively on contact' s'trips iii) and 5 1. The -'contact strip 51] is longer than the strip 51, andbn the outer endthereof is a projection 52 which extends upwardly and engages with a strip' 83 that can be engaged by pencil 12 upon the pencil being extended through the tube 4 5. The strip '53 is fixed to the tube by a rivet '54.

It should now be apparent that there has been provided an attachment for a writing -"board which serves not only to efiect the lighting of the pa per-on the board, but also is tilta ble -'--between two positions so as to either release the paper or 'tohold the paper in position "on the board.

-I-t should also be apparent that the attachment that the light automatically is turned on. Upon return of the pencil the light will be turned off. If the light is still on, the user will be given an indication that the pencil needs to be returned. Accordingly, there is little opportunity for the pencil to be lost, and the user of the board will always have such pencil available.

While only pnearm 35 is shown to be a spring arm, it willbe understqodthat the .other arm 31 can be of the same type. In order that the arm .31] can adapt itself to the board readily, the hole through which the arm 30 extends is tapered. soon :as -the attachment is in place on the board, the arm will be centralized in the opening by the spring 35.

iVifhile various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the appended claims.

-I claim:

1. n :writing b'oardlamp attachment comprisinga tube adapted to permit the passage of light through the :side thereof, a lamp socket secured to the-tube, a lamp bulb in the socket, a second tube attached to the side :of the first tube and adapted to receive a pencil and serving -:as a handle for lifting and lowering the attachment, electric circuit means for supplying (electric :current to said lamp bulb, spring attaching arms extending respectively from the opposite end of thefirst tube and having hook formation adapted to extend over the edges :of the writing board to hold the attachment against iip'Warddisplacezment therefrom, rear ileg 'members projecting respectively fromthe opposite .ends'of the first tube and rearwardly "of the attaching arms, forward leg members pro jecting respectively from the first tube and inwardly of the respective and adj acent rear leg members, said forward leg members =lying forwardly of the attaching arms and adapted to engage a paper sheet to retain the same in place upon the board as the attachment is lowcred-forwardly thereunto, said attachment upo'n being-lifted or lowered pivoting on said rear-leg members as-a'pivo't.
