Notice of Request to amend Specification.

Patent Office,
Wellington, 11th December, 1907.

A REQUEST for leave to amend the specification and drawings relating to the undermentioned application for Letters Patent has been received, and is open to public inspection at this office. Any person may, at any time within one month from the date of this Gazette, give me notice in writing of opposition to the amendments. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

No. 22374.—J. C. Preston.—Improvements in sheep-shears and similar machines for other like purposes. (Advertised in Supplement to New Zealand Gazette, No. 41, of the 2nd May, 1907.)

The nature of the proposed amendment is as follows:—

(1.) To strike out the whole of the specification after the preamble, “to be particularly described and ascertained in and by the following statement,” and to insert instead the following specification:—

The invention relates to shearing-machines, and particularly to the class of said machines driven by a motor actuated by fluid-pressure, said motor being arranged within or upon the casing of the machine. The principal feature of my invention is the employment of a spring bar for oscillating the cutter, said bar being held at its inner end and having its outer end vibrated by a motor, the vibration being effected by bending the spring bar. A convenient motor for use in connection with my invention is driven by compressed air, and is of a type having two connected pistons, the spring bar passing between them. Means are provided for adjusting the tension of the cutter upon the comb of the machine by employing a fulcrum in connection with the spring bar, and by bringing pressure to bear upon the inner end of the bar by a tension screw.

The invention is illustrated in the accompanying drawing, wherein Fig. 1 is a plan; Fig. 2, a vertical central sectional side elevation; Fig. 3, an end elevation of a motor suitable for employment with my machine; Fig. 4, a vertical section of the motor on line 4-4, Fig. 2.

The casing of my machine is in two parts, A and A¹. These parts at their ends form a complete tube, which is screwed to receive the socket H employed for holding the parts together, the socket having a nipple T to which air-tubing may be connected. My spring bar D takes the place of the cutter-lever usually employed, and at its inner end passes through a slot N formed in a circular snug K projecting upwardly from the bottom of the part casing A. The spring bar also passes through a slot O formed in the pillar G. The pillar has a head Q and passes through a hole in the part A, and is received by a socket O¹ projecting downwardly from the part casing A¹. The pillar is screwed at its upper end, and the nut P upon it assists in holding the parts together. The outer end of the spring bar passes through a slot R in a head M, which has the pins S projecting downwardly and engaging in holes in the cutter C, said cutter vibrating radially over the comb B in the ordinary way to perform the cutting operation. The motor F has the two cylinders U and U¹, each containing a piston, said pistons being coupled together by the connecting webs V and V¹. The web V has a slot L which receives the spring bar D. The pistons are reciprocated by compressed air, which is alternately admitted to and exhausted from the respective cylinders by a piston-valve carried in a valve-casing W to which air or other motive fluid is conducted by a pipe J. The motor lies in a bed formed for its reception in the two parts of the casing, which are closed upon it to clamp it securely in position. This arrangement is particularly adapted to facilitate the removal of the motor when required. The pressure of the cutter upon the comb is regulated by the tension screw E, which screws through the bottom of the casing A and engages in a recess in the end of the spring bar. Means such as the milled back nut X is employed upon the screw to retain it in position. The pillar G acts as a fulcrum when the end of the lever is forced up by the adjusting screw.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is—(1.) In machines for the purpose indicated, the employment of a spring bar for vibrating the cutter, substantially as and for the purposes herein specified, and as illustrated in the drawing. (2.) In machines for the purpose indicated, the combination of a spring bar for vibrating the cutter with a motor for actuating the spring bar, substantially as and for the purposes specified herein, and as illustrated in the drawing. (3.) In machines for the purpose indicated, in combination, the spring bar, the pillar which acts as a fulcrum and retainer for the bar, and means for operating upon the spring bar to regulate the pressure between the cutter and the comb, substantially as and for the purposes specified herein, and as illustrated in the drawing. (4.) In machines for the purposes indicated, in combination, the spring bar, a fulcrum therefor, and a screw located beneath the machine and operating upon said bar for the purpose of regulating the pressure between the cutter and the comb, substantially as and for the purposes specified herein, and as illustrated in the drawing. (5.) The improvements in machines for the purpose indicated consisting of the parts combined, arranged, and operating substantially as and for the purposes specified herein, and as illustrated in the drawing.

(2.) To alter the drawings and to add one additional figure.

The applicant states: “My reasons for making this amendment are to more clearly explain and define the invention.”
