[No. 41

action of the aforesaid stamps, although I make no claim thereto.

Amendments.

(1.) To strike out all the words from and including the words “My invention,” line 17, page 1, to and including the words “along the trough,” line 17, page 3; and to insert in place thereof the following words:—

“My invention relates to that class of machinery for cleaning sheep-dags in which the dags to be treated are fed by a horizontal feeder, of the kind used in Jensen’s machine hereinbefore referred to, to the stamps used in that machine, which stamps are so constructed as to crush the clots of dung adhering to the said dags, and to propel them along the trough over which the said stamps are mounted. The said feeder (as constructed by Jensen) consists essentially of battens furnished with tines or prongs, which battens are arranged side by side in the fore part of the trough, into which the dags are fed from a suitable platform. Some of these battens are affixed to the bottom of the trough, the others being capable of reciprocatory horizontal motion, the movable battens alternating with the fixed battens, all the said movable battens being so arranged and actuated as to move simultaneously forwards and backwards, and thus propel the dags to the stamps, and then to retire ready for the next stroke.

“This arrangement is attended by the disadvantage that a pause takes place in the feeding at the end of each forward stroke of the said battens, the feeding being stopped during their retiring motion. Now, the object of the first part of my invention is to remedy this defect wholly or partially, and to give to the movable battens an alternating motion, and thus render the feed more nearly continuous, so that the machine shall do more work in a given time.

“For this purpose I arrange the movable battens in pairs (with the stationary battens intervening between the said movable battens, as in the subsisting arrangement hereinbefore described), each pair being coupled by means of a block actuated from a rocking-shaft, which is actuated by means of intervening rocking-levers from a crank on the main driving-shaft, the relative arrangement of the parts being such that one pair of battens shall feed the dags forward to the stamps while the other pair is retiring, the said dags being prevented by the tines on the stationary battens from being drawn back by the tines on the retiring battens.

“From this description it will be seen that the movable battens have what may be termed a double action, which approximates more nearly to a continuous action than that of Jensen’s machine aforesaid, and that the dags are consequently more regularly and expeditiously fed to the stamps.”

(2.) To substitute for the word “machine,” line 11, page 4, the words “feeder in connection with the subsisting stamps hereinbefore referred to”; and for the same word, line 12, page 4, the words “feeder, stamps, and washing-machine.”

(3.) To insert between lines 23 and 24, page 4, the following words: “I would here observe that the construction of the stamps, and of the mechanism by which they are actuated (which, as hereinbefore stated, I describe merely for the better information of the public, and not as constituting any part of my invention), is essentially the same as that of the corresponding mechanism in Jensen’s machine aforesaid, with the exception of certain improvements in detail which I have made in order to the better operation of the machine.”

(4.) To substitute for the words “The action” to “marketable state,” line 27, page 7, to line 10, page 8, the following words: “The action of my invention is as follows: The dags to be cleaned are fed by the workman down the feeding-platform to the improved feeder constituting the first part of my invention. Here one set of the movable battens f¹, f¹, f², f², propels the dags forward to the stamps while the other set is retiring, which latter set in turn advances, and propels other dags forward to the said stamps while the first-mentioned set is retiring, the battens f¹, f¹, thus alternating in their backward-and-forward motion with the battens f², f², and thus feeding the dags to the stamps in a regular and expeditious manner. When the said dags have been operated upon by the stamps (which, as hereinbefore stated, are essentially of the same construction as those in Jensen’s machine) the said dags pass along the water-race to the improved woolwashing-machine constituting the second part of my invention; and, after having been swirled in the said machine so as to wash out the dung, or a portion thereof, the workman removes them from time to time, and again feeds them on to the feed-platform, the operations of stamping and washing being repeated until the wool is cleared from the dung, when the said wool is taken out in a marketable state.”

(5.) To insert between the words “claim” and “but,” line 15, page 8, the words “And I make no claim to a feeder in which, as in Jensen’s machine, all the movable battens have a synchronous or simultaneous forward-and-backward motion.”

(6.) To strike out the first claim, and to insert instead, “Firstly, the improved feeder hereinbefore described, and illustrated in the accompanying drawings, for feeding sheep-dags to the stamps of dag-cleaning machines of the kind hereinbefore referred to—that is to say, a feeder in which the movable battens are so constructed, arranged, and actuated that one pair of the said battens shall feed the said dags forward to the said stamps while the other pair is retiring, and that the latter pair shall, in its turn, feed the said dags forward to the said stamps while the first-mentioned pair is retiring, the two pairs of movable battens thus severally having an alternate reciprocatory motion, essentially as hereinbefore described, and illustrated in the accompanying drawings.”

The applicant states,—
My reasons for making this amendment are as follows: That since the filing of my said specification I have discovered that the stamps, and the mechanism for actuating them, were not new at the date of such filing, having been embodied in a dag-cleaning machine constructed by one Christian Jensen, of Waipukurau, in the Provincial District of Hawke’s Bay, and that the principle of the improved feeder described in my said specification was not new at such date, a feeder constructed upon essentially the same principle having been embodied in Jensen’s said machine, albeit the feeder described in my said specification is a substantial and important improvement upon Jensen’s feeder.
