ROTARY TIME-TABLE.

Specification of Letters Patent.

Patented Feb. 3,1914.

Application filed May 21, 1912. Serial No. 698,845.

To all whom, it may concern Be it known that I, ARTHUR H. PLEASANTS, a citizen of the United States, residing at Baltimore, in the State of ldaryland, have invented certain new and useful Improvements in Rotary Time-Tables, of which the following is a specification. V

This invention relates to an improved construction in railroad time schedules.

The object of the invention is to provide a time schedule for railroad trains that shall be printed in a novel manner on a suitable card centrally pivoted to a guide or handle, whereby the handle will serve the double purpose of a guide for the eye in reading any particular one of a plural number of'tim'e schedules, and also as a handle that will enable the card to be used as a fan.

The invention is illustrated in the accompanying drawing in which Figure l is a front view of the device, and F ig. 2 is an edge view of same.

The card, A, may be of any suitable material and is preferably disk-shaped, though not necessarily circular in shape; the card is centrally pivoted by a pin, 6, to a handle, C, so that when held by the handle the card may be turned freely or revolved on said pin. Radial lines, (Z, are on the card and extend from the center to, or toward the circumference or edge, e. The straight columns formed by these radial lines may be single or double; when double, one column will have numerals to indicate the hours and minutes of the arrival time of a train, and the other column numerals to indicate the departure or leaving time. The numerals, f, are printed along the radial lines, (Z. The center of the card will represent the terminal of a rail road, as for instance New York city, and each of the several radial columns of numerals may represent a different line of railway leading from said terminal to some distant city, as lVashington or Chicago.

The handle comprises a hand-grasp part, O, that projects radially from the circular or disk,

card; that part, 9, of the handle extending from the circumference or edge, e, of the disk to the center, has a longitudinal slot, h, with which any one of the radial columns of numerals, f, will register,the numerals being exposed to view through the said open slot may be easily read,the slot serving as a guide for the eye in reading.

It will be understood that a plural number, in the present instance eight, of radial time schedules may be employed on the card and any particular one may be read by merely turning the said disk until the desired schedule is in coincidence with the open slot, h. In the present instance the card or disk, A, fits in a slit, 2', formed in the handle-part, 9,- this slit, 2', opens through the handle part in a direction transverse to that of the said reading slot, 9, and the latter opens through only one-half of the handlepart, that is, the half that is at one side of the slit, 2'. Of course the handle-part may be otherwise constructed than as shown in the drawing. This straight handle-part, g, cooperates with the radially-arranged numerals of the time schedules on the disk, A, and serves as a guide for the eye to easily read the numerals. This will be appreciated especially where a person is riding on a train and the jar and swaying motion of the moving car makes reading somewhat diflicult.

Having thus described my invention what I claim and desire to secure by Letters Patent is A rotary time table comprising a fan body provided with radially arranged columns, a handle provided with two arms forming a fork portion, and a pivot uniting the free ends of said arms and passing through said body, one of said arms being provided with a longitudinal opening with which said radial columns may successively coincide.

In testimony whereof I afliX my signature in presence of two witnesses.

ARTHUR H. PLEASANTS.
