CYULOSTYLE PEN.
Patented Aug. 12, 1890.
UNITED STATES PATENT OFFICE.
DAVID GESTETNER, OF LONDON, ENGLAND.
CYCLOSTYLE-PEN.
SPECIFICATION forming part of Letters Patent No. 434,331, dated August 12, 1890.
Application filed September 19, 1888. Serial No. 285,823. (ModeL) To all whom it may concern:
Be it known that I, DAVID GESTETNER, manufacturer, a subject of the Queen of Great Britain, residing at 70 and 71 Ohiswell Street, in the city of London, England, have invented new and useful Improvements in Oyclostyle-Pens for Producing Stencils to be Employed in the Reproduction of Writings, Drawings, and other Delineations, of which the following is a specification.
The invention has for its object improvements upon an invention for which I obtained Letters Patent dated November 28, 1882, No. 268,009.
I-Ieretofore the perforating-wheels of cyclostyle-pens have been mounted on an axis projecting from the side of the stem or holder, by which construction it was requisite that the pen when in use should be held in such manner that the perforating wheel should be to the right of the stem or holder and with its periphery moving in planes running more or less nearly from top to bottom of the paper. lrVhen such a pen is otherwise held, the writing is liable to be faulty and the stencil-paper to be torn, in addition to which the use of the pen is somewhat restricted, as few but accustomed hands can use it successfully. Now I have discovered that if the cyclostyle-wheel is mounted on the stem or holder in such a position that the periphery thereof shall, when the pen is in use, move in planes running more or less nearly in line with the lines of writing and revolve in a plane more or less nearly perpendicular to the paper, much greater freedom is obtained in the use of the cyclostyle-pen, and better results are consequently obtained.
In the accompanying drawings I have illustrated the form by which I carry my present invention into effect.
Figures 1 and 2 are respectively a plan and side view of a cyclostyle-pen, drawn to the natural size, and Fig. 3 is a side view of part thereof, drawn to an enlarged scale.
In all the figures like parts are indicated by similar letters of reference.
a represents the cyclostyle-wheel,and b the stem or holder. The wheel a is mounted in front of and carried by a fitting c, which is shaped to imitate an ordinary barrel-pen. This fittingc has a single point 0', bent at an angle somewhat downward, so as to be substantially perpendicular to the paper when in use, and the wheel a is mounted on a stud or axis fixed in such bent point 0 and standing outward therefrom so as to be substantially parallel with the paper. By this construction of pen the right position in which to use the same is indicated by the shape of the fitting c. The downturned pointot' the fitting, it will be seen, is also turned or inclined slightly to the left, so as to cause the wheel to revolve substantially lengthwise of the up and down strokes or lines of the writing, as the majority of the strokes are formed on inclines ranging between forty-five and ninety degrees.
The dotted lines D indicate the stencil-paper, the pen being used at about the angle shown in relation to the paper.
I would here remark that the forms of holder and fitting may be varied without departing from the peculiar character of my invention.
Having now particularly described and ascertained the uatu re of my said invention and in what manner the same is to be performed, I declare that what I claim is In a cyclostyle-pen, the combination of the fitting having a single point bent downward so as to be perpendicular to the paper, an axle secured to said point and projecting outwardly therefrom so as to be parallel with the paper, andaperforating-wheel mounted on said axle in front of said point, substantially as set forth.
D. GESTETNER.
