Notice of Request to amend Specification.

Patent Office,
Wellington, 4th February, 1903.

A REQUEST for leave to amend the specification 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. 14761.—17th April, 1902.—William Henry Gordon, of 69, Lyons Street South, Ballarat, Victoria, Engineer and Blacksmith. An improved hub or boss for fastening to a shaft any part of a machine that causes or is caused by the shaft to revolve.

The nature of the proposed amendments is as follows:—

1. To alter the title to “Improved means for securing hubs or bosses on rotatable shafts,” lines 5 and 6, and 10, 11, 12, of page 1.
2. To strike out the words “in the County of Grenville, in the,” line 8, page 1, and to insert the words “and Commonwealth of Australia” after “Victoria,” line 9, page 1.
3. To insert the following paragraphs after the paragraph ending “following statement,” line 14, page 1:—
   “ This invention consists in improved means whereby hubs or bosses may be readily fixed and adjusted on rotatable shafts in such a manner that the strain is distributed over a much greater surface of the shaft than heretofore, and the hub or boss held as firmly and in as true a bed as if shrunken on, whilst at the same time the shaft is not weakened by cutting a key-way therein.
   “ Referring to the accompanying drawings,—
   “ Fig. 1 is a vertical transverse section through a hub and shaft showing the parts loose before the key is inserted, and Fig. 2 is a similar view with the parts locked by the key, whilst Fig. 3 is a side elevation.”
4. To insert the word “rotatable” before “part,” line 15, and to strike out the words “that causes or is caused by the shaft to revolve,” lines 15 and 16, page 1.
5. To strike out the words “to any extent and for a distance of,” and to insert instead “for a part of its circumference, preferably,” lines 18 and 19, page 1; and to strike out the words “half its circumference so as to allow of the free revolution of the shaft (a) within this enlargement,” and to insert instead “and so that the shaft fits loosely therein,” line 19, page 1, and lines 1 and 2, page 2.
6. To omit the words “or tapering key-ways,” lines 2 and 3, to insert the word “is” before “cut” and “said” instead of “this,” and to omit “aforesaid,” line 3, page 2.
7. To insert, instead of the words “or within this said enlargement,” the words “or a plurality of such key-ways may be provided”; and instead of “and a tapering key (d) or tapering keys made to fit the said key-way (c) or these said key-ways,” the words “and a tapered key (d) is made to fit this key-way (c) or keys made to fit these key-ways,” lines 4 and 5, page 2.
8. To strike out the words “Place the part of machinery (b) which is to be fastened to the shaft (a) upon,” and insert instead, “In putting this invention into practice, the boss or hub (b) is slipped over,” lines 6 and 7, page 2.
9. To omit the words “and in as nearly its correct position as possible,” and the words “drive home the key (d),” lines 7 and 8, page 2, and to insert instead the words “the tapered key (d) driven.”
10. After the word “position,” line 11, page 2, to insert the sentence “In this manner a large bearing-surface is obtained with much more satisfactory results than heretofore.”
11. To omit the five claims and insert the following claim:—
    “Improved means for securing bosses or hubs on rotatable shafts, said means consisting in an otherwise truly bored boss having a portion of the circumference of its bore enlarged diametrically, and a key way or ways in said enlargement for a locking key or keys, substantially as and for the purposes specified, and as illustrated in the drawings.”

The applicant’s agent states: “My reasons for making this amendment are as follows: I am advised that the amendments are necessary in order to clearly describe the invention and define the claimable matter.”

Registrar.
