Moneyweight Scale Co. v. Toledo Computing Scale Co.

1. Patents (§ 141*) — Reissues—Validity. Authority to grant reissue patents is derived exclusively from Rev. St. § 491G (U. S. Comp. St. 1901. p. 3393), and the commissioner goes beyond' his jurisdiction if he grants a reissue for an invention other than the one disclosed and described in the original patent, which, by reason of inadvertence, accident, or mistake, is inoperative to secure the monopoly it shows on its face was intended to be secured. [Ed. Note. — For other cases, see Patents, Cent. Dig. §§ 206-213; Dec. Dig. § 141.*] 2. Patents (§ 141*) — Reissues. The inadvertence of the solicitors of an applicant for a patent is liis inadvertence, and, on the other hand, their erroneous judgment in submitting to the rejection of claims is his erroneous judgment, and he is estopped from presenting any of such rejected claims in an application for a reissue. [Ed. Note.. — For other cases, see Patents, Cent. Dig. § 211; Dec. Dig. § 141.*] 3. Patents (§ 141*) — Reissues—Inadvertence. Where none of the original claims presented by an applicant for a patent was adequate to cover the invention disclosed by the specification and. drawings, acquiescence in the rejection of such claims is not an abandonment of the invention as an entirety, and the failure of his solicitors to submit adequate claims is an inadvertence which may entitle the applicant to a reissue. [Ed. Note. — For other cases, see Patents, Cent. Dig. § 211; Dec. Dig. § 141.*] 4. Patents (§ 328*) — Validity and Infringement — Computing Scale. The De Vilbiss reissue patent, No. 12,137 (original No. 649,913), for a computing scale, is not invalid as departing from the original invention, and it also covers a true combination which produces an improved result and discloses invention. Also, Held infringed.

Appeal from the Circuit Court of the United States for the Eastern Division of the Northern District of Illinois. Suit in equity by the Toledo Computing Scale Company against the Moneyweight Scale Company. Decree for complainant (178 'Fed. 557), and defendant appeals. Appellee obtained against appellant a decree for an injunction and an accounting,, by reason of infringement of reissue patent No. 12,137, July 28. 1903. to lie Yilbiss, appellee’s assignor, on an improved computing scale. 178 Fed. 557. Assignments of error allege invalidity of the reissue, want of invention, aggregation, and noninfringement. Fig. 2 of the drawings is given in VIS Fed. on page 565. The original patent No. '649,915, May 22, 1900, drawings omitted, reads as follows : “This invention relates to scales, and more especially to that ^ class thereof known as ‘price scales," which employ a pendulum and are adapted to compute the total selling price; and the object of the same is to effect improvements in devices of this character, more especially improvements over my former patent, dated March 14, 1899, and numbered 621,297. " “'To this end the invention consists in the details of construction hereinafter more fully set forth and claimed and as shown in the accompanying drawings, in which — ■ “Figure 1 is a side elevation of this scale complete. Fig. 2 is a similar view with the front plate of the casing removed, and hence showing a section. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. “Referring to the drawings by reference letters, A desiguales the scale beam, fnlcrwmed at a in the usual manner, as on a knife edge, and C is a second pivot or knife edge which in the present instance supports the standard, M, of the platform or table. R, although it. will be clear that by a slight change the well-known pan could be substituted for the table without departing from the spirit of my invention. Nothing new is claimed for this much of the device. “The letter A’ designates an auxiliary or tare beam connected and moving in unison with the main scale beam A, and on this auxiliary beam is mounted a weight, a-', adapted to be moved to counterbalance or offset the weight of the crock or receptacle for containing the matter being weighed. Said auxiliary beam preferably extends past the fulcrum, a, and is made as long as convenient in order to give as large a space as possible for each unit of weight, and to this end it is marked with graduations, as shown. “The letter 15, Fig. 3, designates bearings of an.v suitable character fast within the housing 15. D' are knife edges or pivots for said hearings, and I) is a pendulum mounted thereon and hanging normally vertical within said housing, its body carrying a weight. .T, of any kind and being adapted io swing outward through a slot, H.. properly located in tile side of the housing, as shown. Around said knife edges, I)', is a disk, D", rigid with the pendulum and having therein at one side of and normally above the center a knife edge or pivot. N. from which a link or connection, P, leads to the inner end of the beam A, as shown, and from the diametrically-opposire side of this disk projects a screw. A*', currying an adjustable cormterpoise-weight, n', to offset the weight of the link, F, l>y reason of the fact that it stands always opposite the knife edge. N, and hence increases and decreases in leverage as the link increases and decreases. “The lei ter 7. designates an upright cylinder containing mercury, oil, or other fluid agent sufficiently dense to impede movement therethrough, and . 77 is a piston rod led from any part, such as the scale beam. A, and having a piston, 77', necessarily moving in the fluid agent within said cylinder, by -which means vibrations of the scale beam, and hence of its connected parts; is impeded or prevented. “H is a hand or index of any suitable, light material and which is rigidly secured to the disk, D", in a position to stand normally oblique to a vertical, such hand preferably having in its body a series of openings, II', Inscribed herein opposite thereto with the numerals ‘5,’ ‘4,’ *3,' etc., although it will be clear that a hand inscribed in any proper manner and cooperating with the contiguous parts will answer equally well. It will be obvious that the marked portion of the hand moves through the arc of a circle, and in the present instance I provide a graduated table, L. supported by the framework of the machine adjacent said portion of the hand and properly marked with several lines of figures to indicate the total cost of the article being weighed; this cost being the product of the number of units, XT (pounds), indicated also on the table, multiplied by the price per pound, as here indicated on the hand or index. It will be obvious that fractions of a pound or fractions of a cent per pound can be indicated in the same way, as well as the totals thereof. In order to counterbalance the weight of the hand, II, I provide a screw, h', projecting radially from the dish, D", diametrically opposite the index and carrying a counterpoise-weight, h". It will be clear that these weights n' and fc" gain and lose in leverage reciprocally with the link and index and, if necessary, may be adjusted to more accurately counterbalance the same. ...... “The operation of this improved scale is as follows: The machine 'being properly set up and adjusted, let us suppose that a one-pound crock is placed on the table, R, in which it is desired to weigh three pounds of lard at six cents per pound. The seller first adjusts the counterbalance weight, a', to ‘T on the tare beam, A', or to any point where it will offset the weight of the crock; the proper point being indicated by the balance of the scale, at which time the index, H, will stand as seen in Fig. 1. The lard is then placed in the crock, the table, R, and beam, A, descend, and through the link, F, the disk, B", is turned on its center D', thereby causing the index, H, to move over • the table, L, until ‘S’ in the units-line XJ is reached. Meanwhile the piston, Z", in the cylinder, Z, descends within the fluid and prevents undesirable vibrations of the index. Opposite the uppermost opening, IT, here shown in the index, is marked the figure ‘6,’ indicating that price per pound, and my table is so arranged that when the index stands to indicate ‘3’ units the operator may read through this opening the product of three times six, or éighteen, which is the total cost of the merchandise being sold. ... • “What I claim as new is— “1. In a scale, the combination with the central pivot, a disk mounted thereon and having a pendulum hanging normally vertical and an index standing normally oblique, a link-pivot connected with this disk and standing normally above said central pivot, a screw projecting from the disk opposite the link-pivot, and a counterbalancing weight adjustable on this screw; of a table with which the index coacts, a beam mounted on a fulcrum, a pan or platform, "“and a link connecting said beam with the link-pivot, all substantially as and for the purpose set forth. “2. In a scale, the combination with the housing having bearings, a disk having a central pivot mounted therein, a pendulum hanging normally vertical from the disk, an index standing normally oblique to this pendulum, a link-pivot connected to the disk and normally above its central pivot, screws projecting from the disk, and counterbalancing weights adjustable on such screws; of a beam mounted on a fulcrum, a pan or platform, and a link connecting the beam with the link-pivot, all substantially as described.” Application for reissue, filed November 16, 1901, was based on the inadequacy of the original patent (apparent on tl\e face thereof) to secure the invention described and disclosed in the patent, and on the "inadvertence of the attorney (apparent on the face of the patent and the proceedings to obtain it) in failing to present for allowance any claim that would cover the invention described and disclosed as the patentee’s invention in the_ drawings and specification. Between the granting of the original and the application for reissue, no intervening rights of any sort accrued. . The specification of the reissue was written afresh; but we agree with the Circuit Court and with appellant that this rewriting unnecessary, that no new matter was introduced into the specification, and that the reissue claims may as well be read upon the original specification. Claim 8 of the reissue is as follows: “In a computing scale, the combination of a price-computing table, L, provided with graduations and numbers indicating the values of different quantities of commodities at different prices per pound, the disk or hub, D", provided with the knife edge trunnions, B', projecting from its front and rear sides and resting in supporting-bearings, E, the index hand, II, rigidly secured at. its lower end to the disk, D", and at its upper end cooperating with the table, L. and provided with a series of numbers indicating prices per pound, the vertically-depending weighted pendulum, _D, rigidly secured at its upper end to the disk, D", the link-pivot, N, carried by the disk, D”, and normally standing at a point above the pivotal axis of the latter, means carried by the disk, D", for counterbalancing the weight of the index hand, H, and link-pivot, if, the scale beam, A, fulcrumed near its outer end upon a suitable support at a, and connected at its inner end with the link-pivot, N, by the link, F, the platform, R, mounted on the beam. A, between the fulcrum, a, and the link, F, the tare beam, A', mounted on the scale beam, A, the poise, a!, mounted on said tare beam, the dashpot. Z, and the piston. Z", moving therein, and having the upper end. of its rod, Z', connected to the scale beam adjacent the link, F; substantially as and for the purpose set forth.” Other reissue claims are for combinations of smaller numbers of the same elements, sufficient to cover an effective computing scale of the particular type pictured and described in the specification, but without the dashpot and the tare beam or without one or the other.
