FUSIBLE-LINK HEATER Specification of Letters Patent.
Patented Jan. 3131, 19116.
Application filed July 29, 1915. Serial No. 42,509.
To all whom it may concern:
Be it known that I, EDWIN TURNER Cors- LAND, a citizen of the United States, and residentof the city of New York, in the county of Kings and State of New York, have invented a new and useful Improvement inFusible-Link Heaters, of which the following is a specification.
The invention consists of an electrical heating unit applicable to any fusible link by means of suitable binding clasps, and also of the various details of construction and the combination of the several parts, as will be more fully described and pointed out in the claims.
Reference is to be had to the accompanying drawings in which Figure 1 is a side elevation of a fusible link and heater and Fig. 2.is a front elevation of Fig. 1. Fig. 3 is a top plan of Fig. 2.
The common type of fusible link consists of two members'soldered together with low fusing solder, and in my improved fusible link the numeral 1 indicates onesuchlmemher; my second member 2" dilfers from the member 1, in that it is provided with binding clasps 3, to form an attachment for an electric heating unit. The members 1 and 2 are soldered together with low fusing solder 4, in the usual manner, and within tlie binding clasps 3 is removably held an electrical heating unit 5, which may be de fusible link by withdrawing it from the binding clas s 3. This heating unit 5may bepreferab y brought into effective heat conductive contact with the means of plastic metallic amalgam or alloy 6, such as is sometimes used in connecting switch board bus bars to prevent corrosion and a drop in voltage. The heating element 5, is shown provided with an electric wire connection 7, and the other terminal of the electric circuit through the heating unit 5, may be grounded through the fusible link in the usual manner. The fusible link is provided with holes 8, to connect it to a sprinkler head or.
other device in the usual manner.
Reference is made to my Patent No. 1,029,277 dated June 11, 1912, in which a form of fusible link is shown having a heat ing unit integral with the link. This patent shows a link combined with head, but I do not limit the present invention to fusible links for sprinkler heads, nor do I limit myself to the exact construction shown in the drawings.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. The combination of a fusible link cona sprinkler ,7
sisting of two separable members soldered together and a removable electrical heating unit attached-to one of the members and independent of the other member.
2. In a fusible link device, the combination of a fusible link consisting of two separable members soldered together, an independent electrical heating unit and means for attaching the electrical heating unit to one of the members of the fusible link.
3. The combinationof a fusible link consisting of two separable members soldered together, one of the members being provided with binding clasps, and a heating unit held by the binding clasps.
4. The combination of a fusible link consisting of two separable members soldered together, one of the members being provided with binding clasps, a heating unit held by the binding clasps and an amalgam heat conductor between the heating unit and the member provided with the binding clasps.
