THOMAS B. BRIGGS, OF BROOKLYN, NEW YORK.

IMPROVEMENT IN PEN AND PENCIL CALENDARS.

Specification forming part of Letters Patent No. 133,695, dated December 10, 1872.

To all whom it may concern:

Be it known that I, THOMAS B. Barees, of Brooklyn,'in the county of Kings and State of NewYork,haveinvented certainnewand useful Improvements in Pen and Pencil Calendars; and I do hereby declare that the following is a full, clear, and exact description thereof, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing and to the letters of reference marked thereon which form a part of this specification.

Figure 1 is a view, in side elevation, of a pencil embodying my principle or invention; Fig.2 is a view thereof, partly in section and partly in elevation; and Figs. 3 and 4 illustrate, respectively, a side view and a sectional one of a modification of my device.

In Fig. 1, D is a piece'of rubber, having av flange setting into the annular flange-seat E.

G is'an ordinary peucil,.which is enveloped at and a suitable distance below its upper end by an elongation of the said seat. This elongation has imprinted upon it seven columns of figures indicative of the days of the month. A short distance from or directly below its flange the seat or tubeE is diametrically contracted, within which contraction or recess is inserteda ring or band, A, bearing the letters which stand for the days of the week, and is the part that turns.

In the modification shown in Fig. 3, the fig ured band or'tube E is movable about the let- .tered one A, the latter being stationary, clinched over the rubber-head I) at f, passing down behind B,and turned out at the bottom to prevent B from slipping 'off. My invention consists of a calendar attached to a lead-pencil, &e., and is embodied in devices substantially as shown in the drawing.

Upon one piece I place the numbers indicating the days of the month, and upon another piece I place the letters indicating the days of the week, sothat when the first day of the month is placed in juxtaposition with the proper day of the week, the calendar is set for the whole month.

I propose sometimes to place on another piece the months, so that the calendar will show the month,the day, and the date but as no one is ever in doubt as to the name of the month, I do not propose generally to take notice of the months.

I propose to apply my invention to pencils, as dates are rarely required except when using a pencil.

As shown in Figs. 1 and 2, the ring or band A bearing the days of the week maybe retained by and turn in an annular groove or recess in the band B, which bears the numbers of the days of the month and the top may be so shaped with a bulged ring or its equivalent E, in Figs. 1 and 2, as to inclose and firmly retain a rubber head, I), or instead of a rubber head a stone or other fancy head may be held.

Another form, shown in Figs. 3 and 4, may

be employed, clinching over the flanged portion of a rubber or other head, the letters being stationary and the figures'being upon a band, B, which turns upon A, and is prevented from slipping oft by swagingthelower end of A so as to come out flush with the surface of B. c

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

The peculiarly-constructed eraser-holder E and the tube 13, forming a calendar jointly with the eraser D and a pencil, O, or penholder, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand.

THOMAS B. BRIGGS.
