Definitions

  • FREDERICK C HINGSBURG, OF BAIiTIMORE, MARYLAND, ASSIGNOR '10 AMERICAN GASACCUMULATOR COMPANY, OF ELIZABETH, NEW JERSEY, A CORPORATION OF NEW JERSEY,
  • this phenomenon may be employed or made use of for the purpose of controlling apparatus of various kinds, but more particularly apparatus located in the open air and subjected to atmospheric conditions. In such case the variations of themoisturo in the at-,
  • mosphere is manifested in the said material by the expansion or contraction thereof whereby means is operated for performing such functions as those for which the apparatus embodying such means may be adapted. It is well known that the humidity of theatmosphere Varies from zero to a maximum at which precipitation is manifested in the form of rain, snow or the like.
  • a more specific object of my invention is to provide means whereby the expansion and contraction of the sensitive element of an apparatus, as above described, maybe operated to open or close an electric circuit or conduit which, either directly or through-a relay is adapted to put into or out of operation a sound signal; or to operate a ,valve to open or close a conduit through which gas or other fluid is adapted to flow.
  • FIG. '1 is a view in side elevation of an apparatus embodying my invention, portions of one side being broken away in order that the operative parts may he more clearly disclosed;
  • Fig. 2 is a view infront elevation, of said apparatus;
  • Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig.1;
  • Fig. 4 is a tran-sversesectional view taken .on the line 4 -4 of Fig. 1.
  • 1 designates a side plate provided withinwardly extending lugs 2 and 3, the former being situated at .the upper and lower ends of the rear-edge of the said plate and the latter at the upper and lower ends of the front edge thereof.
  • the plate 1 is provided with elongated openings, as indicated at 7, and the plate Slikewise is provided with openings, not shown. The upper and lower ends of the space between these plates is open. It will be seen, therefore, that the at mosphere has free and unimpeded access to the space between the said plates so that any element or part of the apparatus which'may be sensitive to moisture which may be present in the said space is fully and freely exposed to the atmosphere so that the full eilect of the moisture thereon may be had.
  • the plate 1 is provided with additional inwardly extending lugs or projections 10 which are situated near the opposite ends thereof and the outer ends or which may be connected to the plate 5 by means of screws if desired.
  • the lugs it: constitute the supports for the controlling elenu:11-. 11 which is adapted to expand with increasing moisture or humidity of the atmosphere and to contract when such humidity or moisture decreases.
  • the element 11 consists preferably of human hair,
  • the opposite ends thereoi are bent around the upper edges of the lugs and are clamped underneath clamping plates 12 which are clamped against the roar sides of the said lugs by means of screw bolts 13.
  • the strand of hairs 11 are arranged in a manner similar to that of the hairs upon the bow of a violin. They are drawn taut and the opposite ends thereof are clamped underneath the clamps 12 so that they may be permanently held in place.
  • the placing of the hairs or other material upon the lugs 10 shouldbe effected in a dry atmosphere; that is, when in a dry state.
  • the said member 20 is provided at a point intermediate its ends, nearer its upper than to its lower end, with a pin 23, the oppositeends of which are pointed and engage in seats therefor upon the inner ends of bolts 2% adjustably secured in the sides 1 and 5 of the apparatus.
  • the pivoted member 20 is operatively connected with the sensitive strand of hairs 11 by means of a fiat link member 25 having an opening 26 there through through which the said hairs extend and against one side of which they contact, as shown in- Fig. 3.
  • the link member 25 is provided with a reduced portion 27 which extends between the opposite sides of the member 20 and is provided with outwardly extending projections 28, the inner edges of which are seated in notches 29 in the front edges of the opposite sides of the swinging member 20.
  • the link 25 engages the strand 11 of hairs at a point substantially midway between the opposite ends 181680 lower end of the swinging member vided with a contact 80 secured i any suitable manner, as by solder F or the purpose or tending to c causing outward swinging inc lower end of the swinging n the expansion of the centre have provided a coiled spi constantly under tension and the of which is connected to the mend point near the lower end of the upper end.
  • the rod 35 is adjustable and may be adjusted inwardly and outwardly and is adapted to be held in its adjusted position by means of the lock nut 37.
  • a conducting wire or lead line 40 is connected to the member 235 by means of a binding nut 41. The opposite end of the said conductor or lead line is con nected to one side of a battery 42.
  • A. second lead line or conductor 43 is connected at one end to the opposite side of the said battery and its opposite end is connected to a post 44 secured to a projection 45 upon the plate 1.
  • the conductor or lead line 43 is connected, in the construction shown, with a relay, as indicated at 50, the operation of which is well understood.
  • the expanding and contracting element 11 expands as the moisture or humidity in the atmosphere increases and as it expands the wire 31 contracts to cause outward swinging movement of the lower end of the pivoted member 20.
  • the contact 31 contacts with the contact 34 upon the rod 35 to complete the circuit through the wire 40, the battery 42, the wire 43 and the frame structure so as to operate the relay at 50.
  • the passage of current through the circuit of the relay may be caused to operate a fog signal or any other device or apparatus.
  • the essential feature '7 of my invention is the provision of means whereby the expansion and contraction of an element due to the increase or decrease of moisture in the atmosphere may be caused to perform or effect any particularfunction for or to which the apparatus in which my invention may be embodied is adapted.
  • an electric circuit including a contact and a member which member is pivoted intermediate its ends the. upper end of which is provided with a counterbalance weight and. the lower end of which is adapted to swing back and forth be- 'tween the said strand and the said contact to open and close said circuit, a connection be tween the portion of said member below its pivot and the said strand, and yielding means ending to cause movement of the lower end portion of said-member'away from the said strand toward the said contact.
