making the package, and it is desirable, in order to produce a completed product in one operation, that the gumming-mechanism should be a part of the same machine as the wiring-mechanism. It is also frequently desirable to fold the paper after the wire is applied thereto, in order to form it into a receptacle. My present invention therefore includes the devising of an organized machine having in combination mechanism for performing all of these three functions, or the wiring in combination with either a gumming or a folding mechanism, and also mechanism for transferring the blank from each of said mechanisms to the next. It will, however, be understood that I do not limit myself to the use of a gumming or a folding mechanism in connection with the wiring-mechanism, or to the use of either of these mechanisms in connection therewith. If it is desired, the wiring-mechanism may be used by itself or in combination with a gumming-mechanism, or in combination with a folding-mechanism, or, as I have shown it, in combination with both. As I am the first, so far as I am aware, to combine mechanism for mechanically attaching a wire opener with either a gumming or a folding mechanism, or with both of them, I intend to claim these combinations broadly, and without reference to the special construction of any of the mechanisms. While it is not essential to my invention, broadly considered, that any special type of machine for mechanically attaching the wire opener to the blank, or a machine for making such attachment in any special manner, should be employed, still it is a part of my invention, considered within narrower limits, to provide a machine which shall be capable of attaching the wire by causing it to penetrate the material twice, and bending it down thereafter, so that there shall be three parallel strands of wire at the point of attachment to the paper. To this end my invention includes means for feeding the wire, cutting therefrom a proper length, bending down the ends or an end thereof, and causing the same to penetrate the paper, used in connection with mechanism for causing the bent portion of the wire to again penetrate the paper, and for thereafter bending over the end thereof and clinching the same. While it is generally desirable to attach both ends of the wire to the envelope in order that it may not be necessary for the person using the opener to make a selection between the ends, nevertheless I do not wish to limit myself to mechanism for attaching both ends, and I intend to include the adaptation of my invention to the attachment of the opener to the blank at one of its ends. Further, some other portion or portions of the wire opener besides the end or ends thereof may be utilised for the attachment of the opener to the blank without departing from my invention. My invention also includes certain details of construction which will be fully determined in the specification and pointed out in the claims. My invention may be used for attaching a wire opener to any sort of a blank, to be used for any purpose. This blank is usually and preferably of paper, but may be of any other suitable material, as cardboard, thin wood, or cloth. The blanks so wired may be applied to any of a large variety of uses, among which I may specify envelopes, newspaper-wrappers, labels or sealing-strips for boxes, &c.

No. 12624.—18th May, 1900.—WILLIAM PARKER, of Victoria Buildings, 80, Swanston Street, Melbourne, Victoria, Civil and Hydraulic Engineer (nominee of Donald Cameron, of 1, Sylvan Road, Pennsylvania, Exeter, Civil Engineer; Frederick James Commin, of 7, Bedford Circus, Exeter, Fellow of the Institute of Surveyors; and Arthur John Martin, of Bradninch House, Exeter, Civil Engineer, all in England). Improvements in apparatus for the treatment of sewage or other liquids.

Claims.—In apparatus for the treatment of sewage or other liquids: (1.) The combination with two or more receptacles of a pair of valves for controlling the supply and discharge to each receptacle, each pair of valves being actuated by an independent pair of buckets, the bucket whose descent controls the supply receiving the overflow from another receptacle, and the other bucket which controls the discharge being filled by the overflow from the same receptacle which it discharges, substantially as specified. (2.) The combination with a receptacle which is alternately filled and discharged, of a bucket or buckets receiving liquid for the purpose of effecting such discharge, and an aperture for regulating the flow into such bucket, so that the filling of the same may occupy a certain desired time, substantially as specified. (3.) The combination with a receptacle which is alternately filled and discharged, of a bucket or buckets receiving liquid for the purpose of effecting such discharge, an aperture for regulating the flow into such bucket or buckets, so that the filling of the same may occupy a certain desired time, and means for varying such aperture either by means of a cock or a detachable nozzle, substantially as specified. (4.) A regulating cock or nozzle on the pipe supplying the bucket which controls the discharge of a receptacle, so as to enable the period between the filling and the discharge of the latter to be varied, substantially as specified. (5.) The combination with a number of receptacles, each having separate apparatus for effecting the supply thereto and the discharge therefrom, of a series of overflow-pipes, each fed from one receptacle and conveying liquid for operating the apparatus, whereby the supply to another receptacle is effected, so that several such receptacles are filled and discharged in rotation, substantially as specified. (6.) Overflow-pipes proceeding from the whole of a set of receptacles to be filled and discharged, and connected in a continuous ring, such pipes having branches through each of which a passage to a bucket for regulating the filling of a receptacle is opened or closed by a three-way cock, which may be turned to divert the overflow from the bucket which it would otherwise supply, and thereby cutting out the receptacle, whose filling or discharge is controlled by such bucket from the set, substantially as specified. (7.) The combination with a number of receptacles, each having separate apparatus for effecting the supply thereto and the discharge therefrom, of a series of overflow-pipes for conveying liquid for operating such apparatus, valves or cocks whereby the overflow to one or more sets of apparatus may be prevented, thereby cutting the receptacles to which such apparatus belongs out of the working set, and valves or cocks whereby such overflow may be sent past the receptacle or receptacles so cut out, and to operate the apparatus of another receptacle or other receptacles, substantially as specified. (8.) The combination with the branches leading from a set of receptacles to be filled and discharged to the continuous ring of overflow-pipes, of a check-valve to prevent liquid passing back from the ring into the receptacle which has been cut out, substantially as specified.
