Improvements in Guides for use in Posting or Copying Entries.
I HARRY HOLTON LOVE, of Sacramento, in the County of Sacramento, and State
of California, United States of America, gentleman, do hereby declare the nature of this
invention and in what manner the same is to be perforined to be particularly described
and ascertained in and by the following statement :-
My invention relates to a device which I call a "posting or copying guide."
It consists of parallel opaque strips with transverse uniting-bars and set-screws
whereby the space between the strips may be regulated, and sliding guides upon the
ends of the strips for holding them in proper relative position upon the book from
which the copying is to be done.
Referring to the accompanying drawings for a more complete explanation of my
invention, Fig. 1 is a view showing my device and its application to a book, Fig. 2
shows a portion of one of the strips.
In posting from journal or cash-book to the ledger, book-keepers experience some
difficulty in preventing mistakes-such as reading the name from one portion of the
line and the wrong amount in the column of figures and in copying lists of names,
and in other similar work, such mistakes are apt to be made by missing names or
mistaking lines.
My device is intended to prevent these errors.
It consists of two parallel opaque strips A, which are preferably made of thin rubber
or other flexible material.
These strips have clamps B B' fixed upon them at opposite ends, and rods CC,
extend between each pair of clamps at right angles with the strips A, so as to unite
the two together. The rods have one end secured immovably to one of the strips A
and guides D are fixed to the opposite strip, through which the rods C slide freely, so
that the two strips A may be moved to or from each other, and when the proper space
has been made between the strips the rods are secured in their guides by means of set-
screws E. The opaque strips A are separated so as to leave a space between them
equal to the lines upon the page being copied, the remainder of the lines for a short
distance above and below this one being entirely covered by the opaque strips. At one
end of these strips A are fixed the guide-plates G which fit the edges of the leaves and
the latter, abutting against the shoulders of the guides, as shown, serve to hold the
strips A in a parallel position and allow them to be moved up and down in a manner
similar to the movements of a T-rule upon a drawing-board.
The page of the journal or other book from which the accounts or names are being
copied being exposed, this device will be fitted upon either edge of the book, according
to whether the left or right page is being copied from, and the space between the
strips A having been adjusted to correspond with the distance between the lines on the
book, it will be manifest that all but one line for a short distance on either side of
the open space may be covered by the opaque plates. It will then be impossible to
make an error, as all the words and figures upon that line will be copied or transferred
in their proper position, with no chance of making an error by copying a portion of
the line and then taking figures which may be upon a line above or below.
The device may be similarly used in copying long lists of names and for other similar
purposes.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
--
1. The posting or copying guide consisting of the parallel opaque plates with the

page_text: the plates to be moved with relation to each other, and set-screws whereby they are
held at any given point, substantially as herein described.
2. The copying-guide consisting of the parallel opaque plates with the transverse
adjusting rods and set screws and the hooks or guides fixed at one end of the plates
substantially as and for the purpose herein described.
Dated this 12th day of November 1889.
