AUTOMATICALLY COOLING HOT JOURNALS.
SPECIFICATION forming part of `Letters Patent No. 270,236, `dated January 9, 1883.
Application iilcd August 30, 1882. (No model.)
To all whom it may concern:
Be it known that I FRANZ 0.MAT'1HIEssEN, of Irvington, New York, have invented a certain Improvement in Devices for Automatically Cooling Hot Journals, of .which the following is a specification.
My invention relates to that class of automatically-operating cooling devices in which aV discharge-pipefor supplying a cooling-duid has its mouth closed with a plug or disk of metal which is fusible at a comparatively low means of apparatus which deluges such jour! nals with water or other suitable fluid when" ever they become `overheated, and concurrently sounds an alarm at some prescribed part of the premises, which indicates the room or place where the overheating has occurred.
In order to provide for the removal of the cap of the journal, I make my discharge-pipe movable preferably by securin git to the servicepipe, or branch of theservice-pipe, with aswivelcoupling.. I apply my fusible disk to the lower end ofthe discharge-pipe, and so arrange the pipe with relation to the journal thatit may be adjusted in such position as to bring the fusible disk on the end of the pipe into close contact with the top of the cap. I form my disk of either of the well-known alloys, preferably of an alloy of the class which melts at a temperature not exceeding` that of boiling water. Inside the end ofthe discharge-pipe I provide a valve, to which the melting of the iusible disk gives access, so that it can be closed to stop the flow of water from the discharge-pipe when the disk has been melted oft'.
In carrying out my invention YI arrange in suitable proximity to the shafting a service -pipe or pipes, to which, or to branches" of which, I attach my discharge-pipes, which, by means of swivel-couplings or by' any form of `loosejoint, are made movable, so that they can Vof the journals. I may of course provide a separate alarm for each journal, or I may include -all thejournals in one room or one story of the mill in a single electric-alarm circuit.
The accompanying drawings, illustrating my invention, are as follows Figure l is a section ot' a shaft-journal provided with my apparatus, and Fig. 2 is a transverse section of the same through the line fc :c on Fig. 1.- Fig. 3 is a front elevation of the contact-maker for closing the electric circuit when the fusible disk melts, and Fig.
4 is au elevation of 'a distant annunciator in circuit with the contact-maker.
rlhe drawings represent a shaft-journal ot" tutes the upper half of the bearing, is secured `to the lower part, B, by the'bolts C O, in thev usual manner.
There is larranged in connection with the journal the `discharge-pipe D, thelower end of which is closed by a plug or disk', d, composed of an alloy, preferably of such composition as to melt at a temperature not exceeding that of boiling water. The discharge-pipe D is connected by the swivel-coupling E with the service-pipe F, and is made of suitable length to enable the disk d upon its lower endto bear upon the top of the cap or upon some other convenient part of the journal. When occasion arises to remove the cap the dischargepipe is swung outward into the position shown in dotted lines in Fig. l.
The lower end of the discharge-pipe may have an outside screw-thread formed upon it tion, Dzyand thus make a tight joint between N the sections.
In practice,if a journal becomes overheated, the fusible disk melts and permits the discharge upon ,the cap of water or other coolingiiuid supplied by the service-pipe F.
It will he understood that the pipe for con- IOO with the fusible disk at its lower end in con-v tact with the top of the cap.
-The fusible disk may have a thread formed upon its periphery, and may be screwed into the end of the dischargepipe; or the fusible disk may be cast upon the perforated head d of the valve-stem d2, in which case the male screwthread will be formed upon the periphery of the head d', and the disk will be ot larger diameter than the head d, so that it may bear upon a packing-ring, d3, applied to the end of the discharge-pipe for the purpose ot' making the joint Water-tight.-
Instead ofthe disk being cast into the perforations of the head d', the latter may have the iiaring tongue d4 formed upon its outer face, and the disk may be cast around this tongue. It will be seen that the constructionin either case is such that when the fusible disk is melted and the pipe D is swung' away from the journalccess can be had to the head d of the valve-st m d2, which can then be screwed in, and therebyr the valve d5 can be forced up to its seat d6, thus stopping` the flow of water from the discharge-pipe. 1n its normal position the valve d5 is away from its seat, and .if the fusible disk d melts the cooling-water flows around the valve d5, and is discharged through engine-room, or any appropriate part of the building where an alarm will attract prompt notice.
As electric annunciators and circuit-closers capable of being operated by changes of temperature are Well known7 no especial description of them is necessary. The drawings,-how ever, show al simple contact-maker, which is in the form ci' a fiat spring, G, held under tension by the link G', which is fastened at one end to tllefusible disk d. Wvhen the disk melts the link Gr is released, and the contact-point G2 is thus permitted to be thrown by the spring' G against its seat upon the insulated bar g, with which one end of the aununciator-circnit is connected, the otherend of the circuit heilig connected with the spring G. The electric circuit being thus closed, an ala-rm is given, and the annunci-.ttor indicates the locality where there is an overheated journal. An attendant whose attention has been thus directed to the pointwhere the mischief has occurred can then go to that point and swing the discharge-pipe from thejournal and close the Valve and take such other steps to remedy the difiiculty'as may be required.
1 claim as my invention- The combination ot'a shaft-journal the cap of which is removable,`the discharge-pipe hinged to the ser'vicepipe, its free end over said cap, and so that thedischarge-pipe may be turned from its position for removal or introduction ofthe cap or shaft, a plug fusible at alow temperature, arranged in the discharge-pipe' in close proximity to the cap to hold in suspense the tluid in the pipe, and so that the heat which may be generated in the journal will liberate the liuid and permit its dischargeV upon the journal, substantially as described.
