Patented Aug. 20, 1935 CHART HOtDEfR v I HoraceLI Iouse, Nubieber, Calif. v l, Athenians 19, 1934,fseia111vt. 731,298 Claims. (01'. -82) This invention relates to illuminated holders for time schedule charts used'by locomotive engineers, and particularly represents refinements and improvements over. the devices. shown in my On'e object of the present invention;- asabove indicated, is to refine, improve. andfgenerally simplify the construction of the holder. 'Another object is to combine ina singleunit anillumi 1 nated holder for a schedule. or chart and a flash light :suitable for general utility purposes and such as are now commonly carried by engine men; and so arranged that it addsno expense to the construction of the holder other thanthat of the small reflector and additional light bulb. These objects I accomplish-by. means of such structure and relativdarrangement of .parts as will fully appear by a perusal of .the following specification and'claims. 1 i

. ,:In the drawing similar charactersof reference indicate corresponding parts in .the several views:

. Figure. 1 is'a longitudinal elevationofamyim proved holder. g H Figure 2 is a longitudinal section .ofthe. same partlybrok'en away. 1

Figure 3 is a cross sectionjon the line. .-3:3 of

Figure 2. J y 1 Figure 4 is a longitudinalsectionof the slidable light unit taken on the line 4.-4 of'FigureZ.

Referring now more particularly to the characters of reference on the drawing, the holder comprises a laminated cylindrical barrel which con- I sists ofinnerand outer metal, shells l and 2 'respectively separatedby a lamination oi? stiff insulated material 3. The barreliis provided with a longitudinal slot 4 extending fromione end toward but terminating .short of theoppo'site end. The outer shell 2 terminatesshortof the shell I onone end andthe spacing between its separated .edges isgreaterlthan the width of;v the slot 14.

Also the lamination 3 extends beyond both metal sleeves at q the end of the, barrel opposite; said 9ne-end.,-

.-: :;The.;s'eparated. edges of the inner shell along 7 rails also serve as a support and guide for the sliding illuminating unit by means of which the mileage strip supported by the guides can be read at night as well as the matter on the chart adjacent the slot. This unit comprises metal elements .Tforming a substantial cylindrical housing and separated from each other by an insulation core 8 disposed inside the housingand arrangedso that one end and the adjacent bottom portion. of the housing is left open. xAbulb Sis mounted in the core to face the open end of the housing, one terminalof the bulb spaced relation thereto is a tubular open ended spool ll adaptedto contain a number of dry cells' l2 disposed in contacting end to end alinement. The spool has enlarged flanges. l3 between which the timetable schedule is disposed. Longitudinally alined small rigid rods it are secured to and project toward each other. from the 1 flanges in parallel and close relationship/to the spool, being adapted to project between the leaves ts PATEN S P- t .of the time table atthe junction of said leaves 5 -2 and insulation 3, so that said cap contacts with the. shell .I.. The cap is knurled so that it can be readily turned by hand while ofcourse .be-

ing removable from the barrel. Said cap. how

.ever is prevented from being too readily removed,

without restricting its freedom of rotation, by

suitable means such as a shallow circumferential fridge. It .on the barrel and a cooperating'groove '11 about the bore of the cap. 'Ihelslot dextends through said end of the barrel as stated and the shells are resilient with a tendency. toexpand. ".In. this manner when they arei.-compressed to allow the cap. to extend over the same they will then engage the cap with a frictional grip when .the compressive pressure .is released and will hold the ridge and groove in cooperating relationship.

Removably mounted in the cap end of the spool. is a plug l8 having a spring l9 therein engaging the adjacent end of the adjacent dry cell so that contact between said battery and the inner shell of the barrel is made and maintained.

A ring 28 is rigidly secured to and projects from the plug, serving not only as a means to turn the plug but also to hang the device up when not in terminal and the adjacent end of the adjacent battery I2 and engages the latter. This contact-- strip extends and is connected to the outer shell I so that there is no direct connection between" the shells. The circuit to the. sliding lamp will closed.

The inner shell is connectedito the flash lamp reflector, in order to complete the circuit to the bulb 24 by means of a metal strip: 26 mounted on the insulation lamination 3, which strip at one end engages the reflector and is adapted at its otherend to be selectively engaged-with the inner shell I by a sliding switch 2'! of the usual character used on flash lights. It will therefore be seen that the flash light while using thesame batteries as the chart illuminating light can be,

energized separate therefrom and the energizing of either light will not affect or interfere with the use of the other.

From the foregoing description it will be readily seen that I have produced'such a device as invention Having thus described .my invention' what 1 claim as new and useful and desire to secure by LettersPatent is:

1. A combination chart illuminator and flash light comprising a barrel to receive a rolled chart and having. a longitudinal 'slot through which the chart maybe withdrawn, an electric light mounted on the outside of the :barrel in position to illuminate the withdrawn portion of the chart, another electriclight mountedin the bar.- rel at oneend in outwardly facing relation, abattery mounted in the barrel and. common to both lights, and separate switchesfor the lights;

2. A chart holder including abarrel having a longitudinal slot open to one .endthereof, a: spool to support a chart disposed within the barrel'in concentric relation thereto, and a cap for the barrel rigid with the spool atone endthereof; said cap being turnably and removably mounted on the barrel at the. adjacent end.

the cap without interfering with its freedom of rotation.

4. A combination chart illuminator and flash light comprising a barrel to receive a rolled chart and having a longitudinal slot through which the chart may be withdrawn, an electric light mounted on the outside of the barrel in position to illuminate the withdrawn portion of the chart, another electric light mounted in the barrel at one end in outwardly facing relation, a battery mounted in the barrel, separate circuits between said battery and the lights and including the barrel, and separate switches in said circuits.

5. An illuminated chart holder comprising a I laminated barrel, said barrel consisting of an inher longitudinally split metal shell, to provide a slot along the barrel, an outer metal shell of lesserarcuate extent than said inner shell and a layer of insulating material between the shells;

. a rail formed on the inner shell adjacent and along therefore not be completed unless the switch l0 is g the slot, a cooperating rail on the outer shell, a lamp housing slidable on the rails, an electric light within the housing, means to connect the terminals of the light with the rails, a battery. within the barrel, .and' means to connect thewterminals of the batterywith the inner and outer shells of thebarrel. ii.
