AUGUST F. SLANGERUP, OF NEIV ORLEANS, LOUISIANA.
ELECTRIC ALARM FOR CANE-FEEDERS.
SPECIFICATION forming part of Letters Patent No. 511,866, dated January 2, 1894.
Application filed April 28, 1893. Serial No.4'72,275- (No model.)
To aZZ whom it may concern.-
Be it known that I, AUGUST FERDINAND SLANGERUP, a subject of the King of Denmark, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Electric Alarms for Cane-Feeders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an improvement in electric alarms for cane feeders and its novelty will be fully understood from the following description and claim, when taken in connection with the annexed drawings.
The objects of my invention are to transmit a signal electrically and magnetically and thus prevent an accident to sugar mills or other machinery by giving a signal in an automatic manner. This I accomplish by placing a magnet bar in close proximity to an ordinary cane carrier, and should a piece of metal be upon the carrier, the magnetic bar will be attracted toward the piece of metal upon the carrier, and when thus attracted, will make or break a circuit so as to ring a bell or cause an alarm. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a side view of cane carrier with circuit closed. Fig. 2 shows side view of cane carrier with circuit broken.
Similarletters refer to similar parts throughout both views.
In the drawings A shows a metal disk, having a slot B in same for engaging a hook or hanger O on side of carrier J. The rods 0 are attached to the disk A by any suitable means. On one end of same is a magnet D, while on the opposite end is a counter-balance weight E. These rods are placed in a horizontal position. I also attach a third rod to the disk A in a vertical position,the latter rod being provided with a weight F.
G is a metal point which is attached to disk A, and which forms a contact with a push button H,-said button being so placed as to form a contact with electric wires 1, which are connected to a bell and batteries not shown. The cane carrier is provided with slats L and links K.
M shows cane upon carrier in transit to rollers, not shown, and N designates a piece of metal upon carrier mingled with cane.
In practice the carrier is placed In motion in the usual manner and the cane dumped thereon. The apparatus is placed In close proximity to the under portion of the carrier, and should a piece of metal be dumped upon the carrier with the cane, the magnetD is attracted in the direction of the metal upon the carrier, and the point G is caused to 1mpinge or press the button H, thus causing a bell to ring. By this signal it will be known that there is a piece of metal upon the carrier, and the rollers can be stopped in time to prevent an accident. It is a well known fact that magnetic influence cannot beinsulated, while electrical influence can be insulated, and thus it will be seen that the magnet D will be attracted by any metal that may be upon the carrier.
A striking advantage of my invention 1s 1ts economical construction, and the ease with which the same may be operated, insuring a safe alarm for all pieces of metal, such as bolts, pins, clevises, or other metallic material which may be thrown upon the carrier, and which, if not detected, causes the rollers of a sugar mill to break down, and frequently subjects the entire crop of a sugar planter to destruction.
Having described my invention and the manner in which the same is or may be operated, I would say in conclusion that I do not limit myself to the precise details shown In illustration, as the same may be varied to some extent; but
lVhat I claim, and desire to secure by Letters Patent, is
The combination, of the endless carrier, the movable magnet mounted in juxtaposition to the carrier, and the circuit changer operated through the movement of the magnet, substantially as and for the purpose set forth.
In testimony whereof I afdx my signature In presence of two witnesses.
AUGUST F. SLANGERUP.
