No. 14213.—12th November, 1901.—EBENEZER HENRY SLATER, of Auckland, New Zealand, Farmer. Improvements in and relating to the cutting-tools of planing-machines.*

Extract from Specification.—This invention provides an improved cutter-tool for use upon planing-machines for tonguing, grooving, and the like. Plane-irons are usually formed in one piece, but according to my invention they are made in two parts—viz., a holder which is bolted to the cutter-block, and a cutter or knife shaped to suit the work to be done and secured in the holder. The holder has an oblong slot to receive the stud bolt by which it is secured to the cutter-block of the machine, and also a slot through one end into which the cutter is dovetailed, the cutter being held securely in position when the holder is bolted against the side of the cutter-block.

Claim.—The combination of a cutter-holder having means by which it may be secured to the cutter-block of a planing-machine, and a cutter dovetailed into said holder, substantially as and for the purpose specified.

No. 14351.—18th December, 1901.—WILLIAM AUGUST EDWIN HENRICI, of 37, Fruchtstrasse, Berlin, Germany, Engineer. An improved rotary engine.

Claims.—(1.) The improved rotary engine comprising a cylinder of the form shown and described, a suitable piston travelling therein, a steam-admission valve consisting of a slotted circular disc or plate located within a recess upon the side or face of the cylinder, such disc being secured to and rotating with the shaft of the engine, a gate for closing the bore of the cylinder operated from the main shaft by means of a cam and system of levers and suitable steam admission and exhaust ports, all arranged, constructed, and operating substantially in the manner described and illustrated. (2.) In a rotary engine of the kind herein specified, a steam-admission valve consisting of a circular plate or disc, preferably bevelled upon its periphery, and provided with an opening therein, such disc being mounted upon and secured to the shaft of the engine, and located within a suitable recess formed upon the side or face of the cylinder, and enclosed therein by means of a suitable cover in which is formed a passage for the admission of steam, such passage being so disposed as to coincide at a predetermined point of the piston’s travel, and so permit of the passage of steam therethrough and through the steam-port to the cylinder, substantially as described and illustrated by the drawings. (3.) In a rotary engine of the kind specified, the means for actuating the gate for closing the bore of the cylinder comprising an arm attached to the spindle of the gate, a rod attached at its upper and lower ends respectively to one end of a lever and to the said arm, such lever being pivotally supported at a suitable point of its length, and being attached at its outer end to an extensible rod or like means, by which the lever’s movement may be communicated to a second lever provided with a roller bearing upon a disc cam and also pivotally supported at a suitable point on its length, all arranged and operating substantially as described, and illustrated by the drawings.

No. 14465.—24th January, 1902.—JAMES MURRAY, of Fairlie, Canterbury, New Zealand, Labourer. Improved clothes-line and clothes-pegs.*

Claims.—(1.) An improved clothes-line and clothes-pegs comprising in combination two clothes-lines fastened at their ends a distance apart to posts, and clothes-pegs hanging from the upper line, each having jaws for gripping the lower line, and a movable band operating to close such jaws on to the lower line, substantially as and for the purposes set forth. (2.) An improved clothes-line and clothes-pegs comprising in combination two clothes-lines fastened at their ends a distance apart to bars, such bars being fastened to posts, and clothes-pegs hanging from the upper line, each having jaws for gripping the lower line, and a movable band operating to close such jaws on to the lower line, substantially as and for the purposes set forth. (3.) An improved clothes-line and clothes-pegs comprising in combination two clothes-lines fastened at their ends a distance apart to bars, such bars being fastened to posts by rotating screws, a centre bar fixed to such clothes-lines, and clothes-pegs hanging from the upper line, each having jaws for gripping the lower line, and a movable band operating to close such jaws on to the lower line, substantially as described and illustrated, and for the purposes set forth. (4.) The combination and arrangement of parts comprising the improved clothes-line and clothes-pegs, substantially as described, and illustrated in the drawings, and for the purposes set forth.

No. 14904.—23rd May, 1902.—GEORGE LUCAS PEARSON, of Lincoln, Canterbury, New Zealand, Farmer. Improvements in apparatus used in boring and artesian-well driving.*

Claims.—(1.) As an improvement in connection with apparatus used in boring, the employment of a guide upon the top of the driving-pipe for the purpose of guiding the boring-rods, substantially as specified. (2.) In apparatus for the purpose indicated, the employment of a driving-monkey working upon the driving-pipe, substantially as specified. (3.) In apparatus for the purpose indicated, a driving-collar internally screwed from each end, and having an inner circular projection forming shoulders against which are butted the driving-pipe and driving-nipple, substantially as specified. (4.) The combination in apparatus for the purpose indicated of a carriage working in vertical guides and carrying winch-drums around which are coiled the driving-ropes, means for revolving the drums to adjust the length of said driving-ropes, a chain passing over guide-pulleys and connecting the carriage with a swivel collar moving vertically in connection with the drive-pipe, and means whereby the carriage is normally drawn vertically upwards by the driving-ropes, substantially as specified. (5.) The combination in apparatus for the purpose indicated of a carriage working in vertical guides and carrying winch-drums around which are coiled the driving-ropes, means for revolving the drums to adjust the length of said driving-ropes, a chain passing over guide-pulleys and connecting the carriage with a swivel collar moving vertically in connection with the drive-pipe, pivoted levers having sheaves at their outer ends around which are passed the driving-ropes, discs carrying crank-pins operating the inner ends of said levers, and means for revolving the crank-discs, substantially as specified. (6.) In apparatus for the purpose indicated, the combination of a lever having a sheave at its outer end around which a driving-rope is passed, the inner ends of said rope being secured, whereby vibration of the lever lifts the driving-apparatus, a crank-disc operating said lever, and means for revolving the crank-disc, substantially as specified.

No. 14918.—21st May, 1902.—OTTO PROLLRUS, of Copenhagen, Denmark, Engineer. Improvements in or pertaining to bearings for centrifugal machines and the like.

Claims.—(1.) A yielding bearing for shafts of centrifugal machines or the like, comprising a coiled spring 3 which is arranged concentrically with the shaft and between the bush 1 and the internal surface of the aperture for the bearing in the frame 2, characterized thereby that the coiled spring bears against the bush and against the internal wall of the aperture so that the shaft can oscillate on its bearing. (2.) In a yielding bearing as stated in claim 1, arrangements by means of which the compression of the coiled spring can be varied. (3.) In a yielding bearing in accordance with the preceding claims, the arrangements that the means for adjusting the compression of the coiled spring comprise nuts screwed upon the bush, or rings provided with a screw-thread and screwed into the aperture in the frame. (4.) In a yielding bearing according to the first two claims, the arrangements that the means for compressing the coiled spring comprise a screw-thread of the same pitch as the said spring, formed either externally on one end of the bush or internally at one end of the aperture in the frame into which the bush is inserted, and provided either at the bottom of the groove or at the top of the thread with notches into which the end of the spring can be inserted.
