Claims.—(1.) In an automatic ore-feeder, a barrel or cylinder into and from which the ore is fed and discharged, and such barrel having intermittent motion imparted to it, substantially as and for the purposes set forth, and as illustrated in the drawings. (2.) In an automatic ore-feeder, a feeding-barrel as above claimed, being provided with a ratchet-and-pawl mechanism, which latter is operated by adjustable connections such as a vertical rod made extensible and reducible in its length by means of a right-and-left-threaded connection, substantially as and for the purposes set forth, and as illustrated in the drawings.

(4.) The general arrangement and combination of an automatic ore-feeder consisting of a barrel rotated in an intermittent manner by ratchet mechanism, which is in its turn operated by the upward stroke of the stamper-shank by the agency of a pivoted arm, which latter connects to such ratchet mechanism by means of an adjustable connection-rod, the whole substantially as and for the purposes set forth, and as illustrated in the drawings.

No. 12101.—16th October, 1899.—JOHN WILLIAM STONYER, of Linwood, Christchurch, New Zealand, Machinery Expert. Improved seed-feeder for agricultural drills.*

Claims.—(1.) An improved seed-feeder for agricultural drills, consisting of a cylinder arranged beneath a hopper, and having a hole for admission of seed therefrom, and a slot parallel with the axis of the cylinder for the discharge of seed, the opening of said slot being adjustable by a slide, substantially as specified and illustrated. (2.) An improved seed-feeder for agricultural drills, consisting of a cylinder arranged beneath a hopper, and having a hole for admission of seed therefrom, and a horizontal slot for the discharge of seed, the amount of opening of said slot being adjustable by a slide working in guides upon the cylinder and clamped in position by a set-screw, substantially as specified and illustrated. (3.) In apparatus for the purpose described, the combination of a cylinder arranged beneath a hopper and having a hole for admission of seed therefrom, a horizontal slot for discharge of seed, means for regulating the size of said slot, a spindle revolving through said cylinder, a collar upon the spindle, and agitating-arms upon the collar, substantially as specified.

No. 12115.—25th October, 1899.—McKAY SHOE-MACHINERY COMPANY, of Portland, Maine, a corporation organized under the laws of the State of Maine, and having its principal place of business at 76, Lincoln Street, Boston, Massachusetts, United States of America (assignee of Louis Amedee Casgrain, of 7, Park Avenue, Winchester, Massachusetts aforesaid, Inventor). Improvements in machines for driving fastenings.*

Description.—This invention has for its object the production of an improved nailing-machine adapted more especially for handling Hungarian nails, said nails having large heads. Heretofore it has been customary, when removing nails from the raceway, to use a separator which acted against one side of the shank of the nail; but such a separator is unreliable in its action, and it is difficult to discharge the nails so that they may be driven straight into the stock. Our improvements have been designed especially to insure the proper presentation of headed nails to the driver-passage and driver; and to do this we have devised a new separator which acts to deliver the nails, one at a time, into the driver-passage in the path of the descending driver, our separator acting first against the heads of the nails, and in one form of our invention it may also act later against the shanks. The lower end of the driver-passage contains jaws provided at their ends preferably with semi-grooves, said jaws being under the control of a suitable spring whereby they are made to position the nails, the head of the nail acted upon by the driver passing through the semi-grooves. The raceway has co-operating with it a knock-off, it acting to throw from the raceway those nails coming down thereon which have their heads abnormally elevated so that they are not seated on the raceway, or which are lodged improperly on the nails hanging properly in the raceway. The knock-off is reciprocated intermittently, and for the best results we have provided means for imparting to it an irregular or variable throw, giving to it occasionally a longer and sharper stroke than usual, to knock off nails improperly lodged on the raceway.
[NOTE.—The number and length of the claims in this case preclude them from being printed, and the foregoing general description is inserted instead.]

No. 12458.—14th March, 1900.—WILLIAM FAIRHEAD, of Broad Street, Palmerston North, New Zealand, Joiner. An improved method of hanging sashes to allow of them being cleaned or glass replaced from the inside of room.*

Claims.—(1.) In a window, a sash provided with slides hinged to the bottom of the sash, and furnished with screws for uniting the slides and sash together substantially as set forth. (2.) In a window, a sash provided with slides hinged to the bottom of the sash, and furnished with screws for uniting the slides and sash together, and a covering-strip, substantially as set forth. (3.) In combination with a window-frame, a top sash hinged at the bottom to side slides and secured thereto by screws, a bottom sash, weights for balancing the said sashes, and stop-beads held in position by screws engaging with plates let into the frame of the window, substantially as set forth. (4.) The improvements in windows and sashes consisting of parts constructed, arranged, and combined substantially as set forth.

No. 12469.—19th March, 1900.—GEORGES TABARD, of 22, Rue d’Algerie, Lyon, France, Engineer. Improvements in apparatus for generating acetylene gas.

Claim.—A carbide-distributor for acetylene-generators, in which the charge of carbide is carried on or by a fixed valve, on or against which bears a movable seat, the movement of which is regulated by the bell of a gasometer, substantially as set forth.

No. 12542.—20th April, 1900.—EDWARD HOPE KIRKBY, of Cromwell Buildings, corner of Bourke and Elizabeth Streets, Melbourne, Victoria, Electrician. Improvements in and relating to closed-circuit fire-alarms.*

Claims.—(1.) In a closed-circuit fire-alarm, a fan or governor as D carried upon a pivoted arm as d², and driven by the rotation in one direction of a disc carrying projecting pins or pegs as a, in combination with a bell-crank lever as F having an inclined, eccentric, or cam-shaped surface as f¹, adapted to hold said governor out of gear with said disc when the latter has been operated, whilst allowing it to move into gear therewith when said disc is set ready for the next operation, substantially as and for the purposes described and explained, and as illustrated in the drawings. (2.) In a closed-circuit fire-alarm, a trigger as G having a flat curved spring as g³ projecting therefrom, so that it will offer a rigid resistance in one direction but not in the other, substantially as and for the purposes described and explained, and as illustrated in the drawings. (3.) In a closed-circuit fire-alarm, a relay having a hook or catch as h¹ attached to the armature, in combination with a pivoted counterbalanced bar or standard, carrying a plate with a letter or other device indicating the particular series of street-boxes from which the indication has been sent, substantially as and for the purposes described and explained, and as illustrated in the drawings. (4.)

(6.) In a closed-circuit fire-alarm, a pin as i¹ mounted upon the ratchet-wheel as I of the indicator mechanism, and adapted to hold a contact spring as i² out of engagement with a contact screw as i³, so as to keep the bell circuit open until the indicator is operated, substantially as and for the purposes described and explained, and as illustrated in the drawings. (7.) The combination and arrangement of the several devices and improvements set forth, and shown in the drawings, all co-operating to provide an effective and reliable closed-circuit fire-alarm.
