Flower v. City of Detroit/Opinion of the Court

by Samuel Blatchford

United States Supreme Court

127 U.S. 563

Flower  v.  City of Detroit

This is a suit in equity, brought in the circuit court of the United States for the Eastern district of Michigan, by James* Flower, Thomas Flower, and George Flower, against the city of Detroit, the fire commission of the city of Detroit, Benjamin Vernon, president thereof, and the board of water commissioners of the of the city of Detroit, for the infringement of reissued letters patent No. 6,990, granted March 14, 1876, on an application filed February 17, 1876, to Thomas R. Bailey, Jr., for an 'improvement in hydrants;' the original patent, No. 75,344, having been granted to said Bailey, March 10, 1868. Among the defenses set up in the answer, it was alleged that new matter, not constituting any substantial part of the alleged invention upon which the original patent was granted, was introduced into the specification of the reissue, and that the reissue is not for the same invention as the original patent, and is void. The specifications and claims of the original and of the reissue are here placed side by side in paral el columns, the parts in each which are not found in the other being in italic:

ORIGINAL.

'To all whom it may concern:

'Be it known that I, T. R. Bailey, Jr., of Lockport, in the county of Niagara and state of New York, have invented a new and improved hydrant fire-plug; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

'This invention relates to a new and improved method of constructing fire-plugs or hydrants; and the invention consists in operating a cylinder valve in a suitable case, and in the arrangement and combination of parts connected therewith, as hereinafter described.

'Figure 1 represents a longitudinal central section of the hydrant, showing the parts of which it is composed, and the manner of their arrangement. Fig. 2 is a cross-section of Fig. 1 through the line, x, x.

'Similar letters of reference indicate corresponding parts.

'A represents the hydrant tube, from which the water is discharged. B is the horizontal section which is connected with the 'water-main' and which forms the valve-chamber.

'C is a loose casing around the hydrant tube for protecting the tube from dirt, etc. D is the cylinder valve which has its seat at its lower end, on elastic or leather packing, secured in a groove, as seen in the drawing at a. E is a rod, having a screwthread on its upper end, by which the valve IS OPERATED. F IS A SLEEVE-NUT, which engages with the screw on the rod, raising and lowering it as the nut is turned. This nut is turned by a wrench on the head, G.

'The sleeve-nut is secured in the cap of the hydrant by a collar, and packing under the hollow cylinder stuffing-box, H, as seen in the drawing. J is a yoke, which is attached to the rod, E, by a set-screw, and which is sequred in the tube, A, and prevented from turning, as it moves up and down, by projecting lugs, as seen in Fig. 2; and it will be seen that the arrangement is such that the rod and valve may be raised and lowered without being rotated. This secures a uniform and perfect bearing of the valve on its seat, the packing, a, remaining undisturbed.

'Provision is made for the discharge of the waste water by an orifice beneath the valve, D, marked 'f,' which orifice is opened and closed by a valve marked 'g,' as seen in the drawing, h is a wing on the top of this valve.

'As the cylinder valve, D, descends, the angular flange, i, on its inside strikes the wing, h, and raises the valve as seen

in the drawing; thus allowing any water which may remain in the hydrant to escape through the orifice, f, and aperature, k. It will be thus seen that no water will be left in the hydrant to freeze in cold weather.

'The tube, A, is secured to the horizontal section, B, by a ring-nut, m, which contains recesses for packing-rings around the valve, as seen at n, n. Packing around the valve is secured by another ring-nut, o, and also under the end of the tube, A, as seen in the drawing.

'P represents the discharge pipe, with a screw for the attachment of the hose, and a cap-piece for covering the pipe when the hydrant is not in use.

'Having thus described my invention, I claim as new, and desire to secure by letters patent--

'(1) A hydrant or water plug, constructed substantially as shown and described; that is to say, with the parts A and B connected together, as shown, and with a cylinder valve and a waste-water valve connected and operated in combination, substantially as herein specified.

'(2) The arrangemento f the parts, A, B, valve, D, case, C, and stuffing-box, H, as lierein described, for the purpose specified.'

REISSUE.

'To all whom it may concern: 'Be it known that I, T. R. Bailey, Jr., of Lockport, in the county of Niagara and state of New York, have invented a new and improved hydrant fire-plug; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which my invention relates to make and use the same, reference being had to the accompanying drawing, which forms a part of this specification.

'This invention relates to improvements in the construction of fire-plugs or hydrants.

'In the drawing, figure 1 represents a longitudinal central section of a hydrant, according to my invention;

'Fig. 2, a cross-section of the same through lines, x, x, of Fig. 1.

'My invention consists in the following parts and combinations, as hereinafter specified and claimed, wherein.

'A represents the hydrant tube, from which water is discharged. B is the horizontal section which is connected with the water-main, and which may form the valve-chamber.

'C is a loose movable casing around the hydrant tube. D is the cylinder valve, having its seat at its lower end, upon suitable elastic packing, secured in a groove, as shown at a. E is a rod, having a screw-thread on its upper end, by which the valve is operated. F is a sleeve-nut engaged with

the screw-nut on the rod, E, lifting and lowering said rod as the nut is turned one way or another. This nut is turned by a wrench or crank, or other suitable device, on the head, G.

'The sleeve-nut is screwed in the cap of the hydrant by a collar, and packing under the hollow cylinder stuffing-box, H. J is a yoke, which is attached to the rod, E, by a setscrew, or its equivalent, and it is screwed in the tube, A, and prevented from turning, as it moves up and down, by projecting lugs, as shown in detail at Fig. 2. It will be noticed that the arrangement is such that the rod and valve may be raised and lowered without being rotated; thus securing a uniform and perfect bearing of the valve on its seat, the packing, a, remaining undisturbed.

'Provision is made for the discharge of the waste water by an orifice, f, beneath the valve, D, which orifice is opened and closed by a valve, g. A wing, h, is provided upon the top of this valve.

'As the cylinder valve, D, descends, the angular flange, i, on its inside, striking the wing, h, raises the valve, as shown in

the drawing, and allows any water which may remain in the hydrant to escape down through the orifice, f, and aperature, K; thus preventing any retention of water, above the freezing level.

'The tube, A', is secured to the horizontal section, B, by a ring-nut, m, which contains recesses for packing-rings around the valve, as shown at n. Packing about the valve is also secured by another ring-nut, o, and also under the end of the tube, A, as shown in the drawings.

'P represents the discharge pipe, with a screw for the attachment of the hose, and a cap-piece for covering the pipe when the hydrant is not in use.

'It will be observed that the casing, C, loosely rests upon the main, B, or upon a branch projecting upward from the same. This casing extends upward, enveloping the main portion of the water-pipe, A, at least that portion which is subterranean. Said casing extends upwards, and fits loosely about the plug or hydrant at the portion A'. Above the upper terminus of the casing, C, is provided the bead, a, upon the

hydrant proper. Sufficient space is left between the bead, a, and the upper terminus of the casing, C, to permit o sufficient up and down play of the said casing, C, for the purpose which will hereafter more fully appear. This distance between the bead and casing may be adjusted to any desired distance, thus lengthening or shortening it, by means of its screw attachment at its base.

'The main function of the casing, C, is to prevent derangement of parts during cold weather by the ground alternately freezing and thawing around the hydrant or plug. This process of freezing causes the surrounding earth, by its expansion, to lift or upheave, and thus be liable to derange the hydrant or plug. This upheaval or movement is received by the casing, C, which, by its capability of sliding loosely up and down, will accommodate the upheaval of the earth above mentioned, without any liability to derange the plug or hydrant. This is the chief function of the casing, C, although it likewise serves the purpose of protection to the water-pipe, A.

'What I claim is--

'(1) In combination with a hydrant or fire-plug, a detached and surrounding casing, C, said casing adapted to have an independent up and down motion sufficient to receive the entire movement imparted by the upheaval of the surrounding earth by freezing, without derangement or disturbance of the hydrant or plug proper, substantially as shown.

'(2) In combination with a hydrant or fire-plug, pipe, A, the supply pipe, B, and cylinder valve and waste-valve, connected and operated substantially as herein shown and described.

'(3) The combination of the hydrant or fire-plug pipe, A, supply pipe, B, valve, D, casing, C, and stuffing-box, H, substantially as and for the purpose shown.'

The drawings of the original and of the reissue are also here placed side by side:

The material difference between the descriptive parts of the two specifications is that, in the reissue, it is stated that the casing, C, is movable, and that sufficient space is left between the bead, a, upon the hydrant proper, and the upper terminus of the casing, C, to permit of sufficient up and down play of the casing, C, to allow it to slide loosely up and down, to accommodate the upward and downward movement of the earth during the process of freezing and thawing, without any

liability to derange the plug or hydrant. The casing could not thus slide loosely up and down unless sufficient space were left between the bead, a, and the upper terminus of the casing. No suggestion of such arrangement is found in the specification of the original patent, and the drawing of that patent shows no space between the upper terminus of the casing and the bead or flange above it. it. This is new matter introduced into the specification of the reissue, contrary to the express inhibition of section 4916 of the Revised Statutes. Claim 1 of the reissue is for an invention not indicated or suggested in the original patent, namely, the independent up and down motion of the casing. In addition to this, the drawing of the original patent shows a close contact between the top of the casing and the bead or flange above it, so as absolutely to forbid any such independent up and down motion of the casing as is covered by the first claim of the reissue, while the drawing, Fig. 1, of the reissue, shows a sufficient space between the top of the casing and the bead or flange above it to admit of such independent up and down motion. Issue having been joined, proofs were taken on both sides, and the circuit court entered a decree dismissing the bill, from which the plaintiffs have appealed. Its opinion accompanies the record, and is reported in 22 Fed. Rep. 292. It held that the reissued patent was in valid, as matter of law, upon a comparison of the original with the reissue. We concur in this view.

It is sought to sustain the validity of the reissue by attempting to show that the model filed in the patent-office with the original applicato n exhibited the invention covered by the first claim of the reissue. It is doubtful whether that fact is satisfactorily established. But, irrespective of this, the case falls directly within the recent decision of this court in Parker & Whipple Co. v. Clock Co., 123 U.S. 87, ante, 38. It was held in that case that what was suggested in the original specification, drawings, or patent-office model is not to be considered as a part of the invention intended to have been covered by the original patent, unless it can be seen from a comparison of the two patents that the invention which the original patent was intended to cover embraced the things thus suggested or indicated in the original specification, drawings, or patent-office model, and unless the original specification indicated that those things were embraced in the invention intended to have been secured by the original patent. See, also, Hoskin v. Fisher, 125 U.S. 217, ante, 834. In the present case it cannot be seen from a comparison of the two patents that the original specification indicated that what is covered by the first claim of the reissue was intended to have been secured by the original. In the present case, also, the reissue was not applied for until nearly eight years after the original patent was granted, and the reissue was taken with the manifest intention of covering, by an enlarged claim, structures which in the mean time had gone into extensive public use, and which were not covered by any claim of the original patent. Infringement is alleged only of claims 1 and 3 of the reissue. As to the casing, C, of the third claim, it cannot, any more than the casing, C, of the first claim, be held to cover a casing which has the independent up and down motion referred to. Such casing must be construed to be the casing exhibited in the drawing annexed to the original patent; that is, one in which the up and down play is restricted by the overlapping bead or flange. On any other construction' claim 3 is an unlawful expansion, in regard to the casing, of what is found in the original patent. In addition to this, if the casing of claim 3 is only a casing which has no end-play, it is anticipated by what is shown in letters patent No. 19,206, granted to Race and Mathews, January 26, 1858, which patent was the subject of the decision of this court in Mathews v. Machine Co., 105 U.S. 54. The decree of the circuit court is affirmed.
