Opinion

HAZEL, District Judge.

By the bill in this case the defendanis, co-partners doing business under the firm of Bronson inkstand Com-pilin', are charged with the infringement of letters patent No. 428,733, granted May 27, 1890, to Ferdinand Guinter, and thereafter (Inly assigned to the complainant. The invention of the patent relates to fountain inkstands, and the patentee states:

“Tim objects of my invention are to provide a new and improved inkstand of the class specified, that shall be simple in eonstnicfion. practical in operation, that may be filled without the removal of any part, and .the parts oí which may be readily separated and replaced for cleaning or other purposes.”

The patentee, in his testimony, states that:

“A further object was to construct, a well from which the ink could not overiiow when standing in a. warm room.”

The'specifications of the complainant’s patent stated that:

“The invention has relation to improvements in that class of inkstands in which the ink is contained in an air-tight cistern, through the top of which is inserted a vertical sliding lube with a funnel or cup shaped top, having its lower end submerged in the ink; and by the depression of which the air in the cistern will be compressed, and force the ink through the tube into its top.”

The inkstand is so construe! ed that in the interior thereof is provided a cup with a circular cavity, having an opening at the top and an opening at the bottom; a tube in the center, guided in its movements by these upper and lower openings, and supported upon an elastic, inverted, cup shaped diaphragm; the elastic diaphragm being-located within the cavity, and its lower edges resting upon the rigid diaphragm formed by the floor of the cavity; so that the operative parts of the well were thus practically all contained within the cap, and protected from the atmosphere. This arrangement, it is claimed by the complainant, provides steady and accurate guides for the dip funnel, and insures that only a definite and certain quantity of ink-will be raised to the dip cup each time the funnel is depressed, thus avoiding an overflow of ink from the funnel consequent upon a slight-depression with the pen in the funnel.

The defense is that, if the claims for the patent are construed to have sufficient scope to include the inks lands of defendant’s manufacture, then said claims and the patent are void, because of anticipation, in the prior art; and, on the other hand, if the claims to the patent are given a restricted construction by limitation to the particular arrangement and operation of the component parts set forth in the specification and drawing of the patent, then the defendant’s inkstands do not embody that arrangement or operation, and do not, therefore, iniringe the patent.

The defense that the patent is void because of anticipation in the prior art is relied on by the patents issued to John R. Droney, No. 421,120, granted February 11, 1890; to Albert E. Dain, No. 428,331. granted May 20,1890; also in Great Britain by letters patent to Felix v. d. Wyngaert, No. 15,393, granted December 15, 1883; Gerald W. Von Nawrocki, No. 4,116, granted November 5, 1887; and in Germany by letters patent to Felix v. d. Wyngaert, No. 36,603, granied February 25, 1887.. In the Droney patent an inkwell is shown which [180]*180has the elements of complainant’s patent, except that the elastic diaphragm is not arranged in the same manner as in the patent in suit. It is clamped at its outer edges against the rigid diaphragm, and it cannot be refilled by lifting the ink tube and ink dip cup as in the patent in suit; and in this regard it seems to me that the patent in suit has a decided advantage over the prior art. In the manner of operation for bringing the ink into the dip cup or funnel for use it is precisely the same as the operation shown in complainant’s patent. While it appears that the Droney inkstand and the devices contained therein show some of those contained in the patent in suit, yet it is essential to ascertain whether or not the differences in respect to the elastic diaphragm, and its method of arrangement, are not of such a nature that the elastic, inverted, cup-shaped diaphragm, which is new, and unknown to the prior art, carries with it an improvement which tends to make the inkwell valuable and economical. The patentee doubtless had in mind, in making the elastic diaphragm enp-shaped, that the pressure upon the tube when the latter was pressed down by the pen would hold the edges of the elastic diaphragm close enough against the rigid diaphragm to cause the air in the well to be compressed, and raise the ink in the dip tube upon the depression of the dip cup, and to render it unnecessary to fill the inkwell by dismembering it, or to let in air, or clean it out. With the Gruinter construction the inkwell is filled by simply lifting tube (F) sufficiently high to raise the diaphragm (I) out of engagement with the diaphragm (D), so that ink may be poured through the tube (F), and the air which is in the cistern may escape between the diaphragm (D) and the diaphragm (I). Another advantage attained by the patent in suit, and resulting from the use of the loose, inverted, cup-shaped diaphragm, is that the ink will not overflow when the well is left in a warm room. It is insisted that in inkwells of the prior art, where the flexible diaphragm is fixedly clamped against the body of the inkwell, the air cannot escape from the cistern to the atmosphere, and therefore, oftentimes, especially when the inkwell is left in a warm room, the ink in the inkwell to some extent expands, and causes a pressure, which forces the ink to rise in the funnel and overflow. While a combination of old devices into a new article without producing a new mode of operation is not invention, yet it is well settled that changing the relative positions of the parts of an invention .does avert infringement where the changing of those positions changes the functions of the parts so that substantially a different mode of operation results, even though the invention remains the same. Fountain inkwells were for some years prior to this invention in general use, and in all of the inkwells having a dip tube and funnel, where it is sought to cause the ink to be raised in the tube for the purpose of supplying the pen, the functions in that regard are the same. A fixed diaphragm is not new; it may be found in the Droney patent. A flexible rubber diaphragm is not new; it is found in the Wyngaert well. But in none of these inkwells do we find the advantage which is claimed by the patentee herein. These advantages are due to an elastic cup-shaped diaphragm, fitting or resting loosely upon the rigid diaphragm over a central orifice and a series of smaller- orifices. [181]*181The pressure of (.he dip tube by the pen will be sufficient to hold the edges of the elastic diaphragm close enough against the rigid diaphragm to form a closure causing the air in the well to be compressed, thereby raising the ink in the dip tube. Depressible funnel inkwells employing a rubber diaphragm in the prior art had clamped the rubber tighily to the body of the well, so that it was necessary to disconnect or disjoint tbe well to fill it, clean it out, or admit air. duinter, ihe inventor of the patent in suit, by his patent has changed this so that Ms inkwell is substantially a different combina!ion. In the English patent of Wyngaeri: of 1885 it is not claimed that the inkwell there described may be filled without the remoral of any part.
