May 9, 1933. H. E. RILEY ET AL FUMIGATOR Filed Oct. 20, 1932 Patented May 9, 1933 vUNITED STATES PATENT OFFICE i HERBERT E. RILEY, l' NEW YORK, AND HARRY J'. TANNENBAUI, 0F FAR ROGKAWY,
NEW YORK` FUIIGATOR Application illed October 20, 1932. Serial No. 638,796.
Our invention relates to apparatus intended for vaporizing fumigants, deodorizer's, etc., and particularly of the type of our application Serial Number 607,950 filed April 28th, 1932.
The main object of our present inventlon is to provide a construction for efficiently vaporizing a material such as paradichlorbenzine for the purpose of exterminating moths and other insects and their larvae.
Such devices must be simple in construction and easy and convenient to use. It is also important that they may. be readily refilled with the vaporizable material. It is further important that the device shall be capable of use in all sorts of circumstances, for instance, by merely setting the device on the floor. It is also desirable that the device be operable electrically and that the electrical unit.
be, readily replaceable.
It is also desirable that the heater vunit be inexpensive and durable and ecient.
All of these features have been carefully considered in developin the invention herein shown and descrlbe We have accordingly provided a receptacle in the form of Va metal shell of cup-like form adapted to hold the vaporizable com ound.
The heater is in t e form of a resistance wire mounted on a cross bar adapted to be supported inthe upper edge of the shell f' close to the surface o the vaporizable compound. The heater unit is preferably de- 'tachably mounted so that it can be moved out of the way when refilling the shell. The shell is also rovided with a detachable cover which iits the rim of the shell and guards the heater unit and when closedsubstantially prevents or minimizes evaporation. This cover is alsoV preferably rovided with a valve-like shutter for contro lin the emission of vapor from the device. T e conducltor -cord leading to the heater is preferably led in through the side between the overlapping edges `of the shell and cover so that the. cover may be removed without disturbing the heater unit ywhich is thus exposed for ins tion and removal. In this way the device may also be used for more. rapid Fig. 3 is a sectional view onthe plane of the line 3--3 of Fig. 1.
Fig. 4 is a fragmentary detail showing the method of positioning the conductor.
Fig. 5 is a perspective view ofa modified form of heater unit.
The shell of the device is preferably formed of sheet metal consisting of the body part 7 and the cover 8 having interttting flanges 9 and 10. The body part of the shell is adapted to contain the fumigant material or compound preferably in the form of a cake 11, which cake will ordinarily fill the body up to approximately the level of the flange 9. The shell may be ribbed o'r corrugated externally as well as internally and the cake wouldordinarily be shape to itthe shell.y f
The cover ma have a central raised portion 12 provide with a valve-like shutter 13 which is mounted to rotate n n central rivet 14. This valve or shutter member has a rim or `flange 15 to facilitate rotation so as to open and close the outlet from the shell or casing.
The heater unit consists of a resistance wire 16 in the form, for instance, of a coil wound on an insulating support 17, for instance, of mica and in turn supported by the cross bar 18 from which of course the resistance wire is insulated. The edges of this cross bar may be bent over in the form of anges 19 to embrace the resistance element in the usual manner and may be further protected by-an insulating member adapted to resist the heat created by the passage of the current through the resistance wire. The conductors ane.preferably led mto the shell through one edge and positioned 1n a notch 26 in the flange 9.
The cover 8 may also be similarly notched at this point to position it with respect to the heater unit and' its conductor.
It will be seen that the outer end of the insulating protector 25 is flanged to assist in tionmg it with respect to the edge of t e shell.
The opposite ends of the cross bar 18 are supporte in opposite sides of the shell for instance in the groove formed by the flange 9. One end of the cross bar may be hin d at 27 to the edge of the shell and the ot er end 28 rovided with a finger adapted to frictionaIlly engage the opposite side of the shell where it may be conveniently positioned by inwardly projectin lugs 29-29.
When the cover is oil it wi be seen that the heater unit is retained in the body of the` shell where it can be readily ins ted.
.When itl is desired to refill the shell the heater unit can be removed or swung up out of the way by rotating it above the hinge 27.
In case the heater unit is damaged it may be easily entirely detached by simply drawing out the hinge pin. By reason of the fact that the heater unit and the conducting cord are in no way attached to or dependent upon the presence of the cover it will be seen that the device may be readily manufactured and assembled most economically.
For instance, the bod and cover of the shell ma be made by s eet metal workers and the eater unit may be made by electrical specialists and the parts readily assembled without the use of any tools and without requiring any electrical skill in wiring onthe part of the assembler.
When the device is to be used it is merely necessary to turn on the current in the heater circuit and open the shutter 13 or remove the cover entirely depending upon the rate at which it is desired to carry out the fumigating operation.
By making the cover shallow and bringin it down close to the heater unit we are ab e to utilize the heat withlits maximum eiciency since there is less loss by radiation.
In Fig. 5 we have shown a modified form of heater unit in which the cross bar 30 supports the resistance wire asv above described, but the cross bar is rovided with two flanges 31 and 32 at opposlte ends which are adapted to rest in the groove of the shell. Preferably the cross bar and flange are so proportioned with res ct to the shell that the heater unit will be rictionally held .1n place when the cover is on. Flange 32 may be rovided with an eyelet 33 to guide the con uctors.
It will be seen from the foregoing that l v fumigant in solid or cake form, it should be understood that many of the advanta the invention might be had with a ixe t of heater in case the fumigant is in a liquid or flake form.
l As the heater unit is mounted directly in the body of the shell close to the vaporant, heat is conducted directly from the metallic cross bar of the heater unit to the metallic shell as well as by radiation to the surface of the vaporant.
The shallow cover serves to reflect the heat from the resistance wire so as to quickly andeilciently heat the material to be vaporized. By leading the conductors in through one ed e of the shell we avoid the danger of over eating which exists when the cord is led in through the center of the top.
