ADJUSTABLE CALENDAR.
Specification of Letters Patent.
Patented June 13, 1916.
Application letl April 28, 1915. Serial No. 24,432.
This invention relates to a device which provides a convenient calendar showing the days of the week and the months, and means to so adjust the device that the days of the week shall correspond with the days of the month on which they occur.
It consists in a novel combination of parts with their adjustable features, and in details of construction, which will be more' fully described by reference to the accompanying drawings in which Y Figure l is a plan view. Fig. 2 is a transverse section at 2 2, Fig. 1.
The body or main portion of my device consists of a rectangular strip of any suitable length. It is here illustrated as representing a rule A, which may have divisions of length marked upon one edge either in inches and subdivisions, 2, or a metric system, or both upon opposite sides. The device may be made of a substance suitable for the purpose. Longitudinally from end to end upon one side, a channel 3 is made having projecting edges, so as to form a substantially dovetailed channel and guide, in which a slidable strip of material 4 is fitted and adjustable in either direction along the channel.
Along the margin of the channel, the days of the week are indicated as at 5, and repeated as often as required and the slidable strip is in like manner marked with the Y vdays of the month as at 6. The number of days in a month are marked, as at 8, so that the first day of a month may coincide with the day of the week in the particularrmontli, to be referred to. This'coincidence will be effected by slipping the sliding port-ion one way or other along the guide channel to the desired point. It is thenretained in place by a locking device 7, which may have one end pivoted to the main part of the device and the downturned opposite end is adapted to engage holes in the slide 4, so as to retain it in the position to which it may have been moved. Advertising and other matter may be printed upon the vacant spaces on the device.
.This construction enables me to conveniently assemble in a single structure a calendar and a measuring scale, which may be conveniently carried in the pocket.
Having thus described my invention, what I claim and desire to secure by Letters Patent is- In an adjustable calendar of the rule type having a slidably mounted strip provided with the days of the month adapted to register with the days of the week'provided on the rule, said slidable strip being formed with a series of holes, a locking device comprising alength of wire pivoted at one end to the rule and having its opposite end free and downturned to engage selectively in the holes of the strip, the intermediate portion of the wire length being arched to afford a grip for manipulating the locking device and the pivoted end extending through the rule and headed to prevent said `end from pulling out.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
