IIVIPROVEIVIENT` IN MACHINES FOR RULING AND COPYING.

` The Schedule referred to in these Letters Patent and part of the sanie- I, GREEN llzIcHnNnY,` of Louisa, in the "county of Lawrence and `State of Kentucky, have invented a `-new and improved Guide andGange for Oopying,Ru `ing, and other purposes, of 7which theffollowing isa.

lhe apparatus which is.'` the` subject of my in vention is constructed with a base-frame, within `which-maybe ,placed the paper lon. which any matter is tof be copied from a book, orv from another manuscript.` i X y y The said 'hook or manuscript is held iny convenient position bya second *traine supported on a car- `riage sliding within the rst, and provided with a bar passing across the page, and moved, ,thronghthe vmedium of connections hereinafter described, by the moi tion ofv said carriage.

` 4A at bar, extending iomA side toside of the carriage across thepaper -being written upon, affords convenient `means ofshifting the carriage and the guide-bar from.` time to time, as the work progresses. i i

The lower transverse bar, which is attached to the sliding carriage, serves asa ruler, when regllirsd, and, for distinction will be termed the ruler- @L 'AF graduated scale, over lwhich the upper guidebar moves, aicrds a gauge for ruling lines accurately `at any distance, by means of the ruler-bar, and a `horlzontal scale `uponthe lower part of the mova-` ble frame may serve as a gauge for vertical ruling.

As there represented,"the motion oft-Iieguidebar I down-or up the face of' the hook-frame will be precisely equal to any motion imparted to the carriage C. Y f

The scale M therefore, which accurately gauges the motion of the bar I, serves thereby-as a gauge for the; position and Vmovement of the ruler-bar G.

In -this case, the primary cords J J pass around the pulleys L at. the lower edge of vthe book-frame, without passing to its upper edge.Y l

The guide-bar is then attached'to secondary cords leysP I", above and around pulleys Q Q, attached to the pulleys L, and of smaller diameter than said pulleys.

The bar I thus forms a constant guide to aid the eye in following the matter to' be copied, and as the writing proceeds down the page, the carriage follows it.
