ings.
Commissioner Fisher has made the follow
ing important notifications of the Patent
oGicc rules, which are to go into effect at
once
UsIrED STATES PATENT oyTIoE,l
June Is, 1860.
1t Is proposed as soon as possible after the
LIST Of July to photograph the drawings Of
the current issues, for the purpose Of attach
ing one copy to the patent, Of placing In the
room OF each examiner a copy OF those be-
longing to his class, of binding n copy Of
each drawing for the inspection Of the pub
lie, and for furnishing certified copies at
cheaper rates than heretofore, The adop-
ton OF this plan has made II necessary to
make essential notifications In the rules re-
latlng TO drawings, TO which the careful at
tention Of inventors and agents Is invited.
II Is absolutely necessary to the success OF
the undertaking that the rules should be
rgidly enforced, and drawings which do not
comply with them will not be received.
The rules, which arc as follows, go into
effect Immediately.
Drawings-The applicant for patent is
required by law to furnish duplicate draw
ings when the nature Of the case admits Of
them. One must be on thick drawing paper
sufficiently stiff TO support itself In the port
folio OF the office for which II is intended.
II must be neatly and artlstically executed,
with such detached sectional views as TO
clearly show what the Invention Is, Its con-
struction and operation. Each part must
be distinguished by the same number or
letter wherever 1t appears In the several
drawings. The name Of the inventor should
be written at the top Of the shortest side,
being considered as such.
This drawing must be signed by the appli-
cant or his attorney and attested by two wit
nesses, and must be sent with the specihca-
| ton.
Tracings upon cloth pasted upon thick
paper will not be admitted.
Thick drawings should never be folded
for transmission, but should'be rolled.
The duplicate drawing to be attached to
the patent, will be furnished by the office at
tho expense Of the applicant and will be a
Photographic copy OF the thick drawing.
| A fec Of flfty cents per sheet of 10 by Is
| inches will be charged, which must be trans
| mitted with thea1nal fec.
If the applicant does not choose to pay
this fee he must furnish the duplicate draw
ing, as heretofore. This must be on tracing
muslin which will bear folding and trans
portatlon, and not on paper. 1t need not be
| forwarded until the patent to which II is to
/ be attached Is ordered to issue. II must
have, for the purpose OF attaching 1t, mar.
gin OF one inch on the right hand.
Copies OF drawings Of patents Issued after
July !, 1869, will be furnished to any one at
the uniform rate OF fifty cents per sheet Of
standard size.
The following rules must be observed In
the preparation Of the drawings In order that
they may be photographed. They must be
| executed In deep black lines, to give dis
tinctness to the point. In shading small
lines OF black, ink should be used.
Pale, ashy tints should be dispensed with.
All colors except black should be avoided,
even In lettering; but light blue, pink and
brown are entirely inadmlssible, and deep
blue, yellow and carmine take black.
The sheet must not be larger than ten
by fifteen inches, that being the size OF the
patent. II more illustrations are needed,
several sheets must be used.
Applicants are advised to employ compe-
tent artists to make the drawings, which
will be returned II not executed In strict con.
formity with these rules, or If injured by
folding. B. y. FISHER,
Commissioner OF Patents.
We have seen specimens Of photographs
made in the manner and from drawings as
prescribed in the foregoing rules, which arc
distinct and clear, creditable to the artist
and satisfactory to all who are interested in
them. The parties executing the work are
skilled in the profession and fully competent
to carry out the design of the Commissioner.
This plan Of photographing drawings by the
office has been contemplated for some time
both on the score of economy to the lnven
tors and convenience to the Patent onlce
but 1t has received a qu!ckcning impulse
from recent legislation in Ohio, Indiana, Iii
nols and Iowa, which requires copy of the
patent, including the drawings, to be showr
in the office of the clerk OF each county ii
which the patented article is offered for sale
