Description
Patented Nev. 1o, 1925.
' UNITED STATES Apilication filed Uetcber 7, 1921i. Serial No. 'wlt V22o ail whom, t may concern.' l Y Be it known that I, HUGO ROBERTS FER- NANDEZ, a citizenof Cuba. and a, resident of Habana, Cuba. have invented a new and Improved Thermostatic Switch, of which the following is a full, clear, and exact dcscription.
y This 'invention relates to therlnostatic switches and more particularly to an electrically controlled' circuit breaker which may be utilized as a flasher or ,for any other purpose desired wherein a circuit is to be automatically opened and closed.
A further object is to provide an expansible frame in which a, twisted flexible de- `vice supports a circuit breaker and is caused to move to open and closed osition at an expansion'and contraction of its support. l
With these and other objects in View, the invention consists in novel features of construction and combinations and arran ments of parts 4'which will be more i'tuly hereinafter described and pointed out -in the claims.
In the accompanying drawings- Figure l is e perspective view of my improved device;
Figure 2 is a View in section on the line 2--2 4of Figure l, illustrating in addition, more or less diagrammaticully, a, circuit i11- cluding a. pair of lamps:
Figure 3 is a view similar to Figure 2 out illustrating a circuit closer in open position.
. 1, l re )resent a pair of hollow peronatede and pre-eral ly corrugated columns which are preferably ot zinc or any other suitable metal which. will readily expand and contract. Tlieseycolumns are connected et their ends by cross-,bars 2 and 3, and are insulated from said crossbars by means of blocks 4., Hooks 5 may he' connected to the upper bar 2 and function as supports, or the device may be supported in any other desired 'mamn ner and in any position desired.
in the upper and lower bars 2 and' ad justing bolts G und 7 are located ii'eferably at the centers of these bars an are prorided with 'nuts 8 to secure them in any desired position of adjustment. A cord, Wire or other 'flexible connecting member 9 is secured in any approvednanner to the bolts 6 and 7, and, adjacent said bolts 6 and J?,
. member 9 is twisted and is under a prede;A
termined normal tension.

THERMOSIJAUEICl SWITCH.
pandedat its interinediate portion and is secured to and supports s plate 10. @n 'this plate 10 a contact ll is secured and is normail? held against a screw contact 12 carn @il ried hy an arm 13 fixed to one of the columns l. A.' coil it connects Contact i1 with the other column l: Normally, the tendency of the member 9 to turn in one direction will hold the Contact il against contact-l2, laut 55 when the columns l expand lono'itudinally and u pull is had on the meniher 9' this member 9 will cause the plate l@ to torri end carry the contect 11 away from contact l2.
To illustrate a practical use ci my im im proved device I show in Figure 2 a. line Wire 15 connected 1n circuit with any suitable source of electricity and also connected with va, peil' oflamps 16 and 17. Branch 'Wires 18 and i9 connect the Wire l5 at 'opposite '35 sides of the lamp l@ with the columns'l so that the lamp it is in a shunt circuit, it is to be understood that the current is only suicient to illuminate one or? the lamps and hence the current will taire time course of 'throu h the Wire i9 and the lamp 1'?, cringing thislamp l? to incsnclesoenee.,
As the temperature oli the columns l rises,
dus to the passage et the electric current or dus to any other cause ci heat, the bars 2 and 3 will ce moved in e. ,direction away from each other causing the plate i0 to turn @0 slightly, separating the contact li from the contact-ll2. This will than causo"V the cur rent topass directly through tire lamp lil and ,illuminate this lam while time other lama 1'? 4 will glow or 'gais ici., is the temperature ci? the columns l decreases, which decreaseis relatively rapid because the calunnie are hollow circulation of sir is permitted throughout, the contact il will more against tire contact i2 and tile circuit will oe as before.
Various slight changes and alterations might ioemsde in the generelfcrni of tire parte described without departing from invention, and hence fi do not limit myself to the precise details set forth but consider myself at liberty to recite auch slight changes and alterations as fa y tali Within, the spirit and scope ot' the appended claims.
