FUMIGATING APPLICATORr Application filed September 29, 1924. Serial'No. 740,568.
To all whom it may concem:
Be it known that I, RALPH M. JACKSON, a citizen of the United States, residing at La Habra, in the county of Orange and I State of California, have invented a new and useful Fumigating Applicator, of which the following is a specification.
My invention relates to measuring devices and gasifiers for applying liquid gases for fumigating purposes under covered trees.
Among the objects of this invention is} to provide eflicient means in a device of this character whereby vertically disposed lever actuating means for producing pressure may v sions from said pump means through disbe employed with a vertically disposed pump measuring means, and manually operated nozzle check valve means co-operating with said pump means, and means whereby a series of fixed measurements may be measured and discharged in intermittent expulcharge nozzle meansbeing laterally spaced from and in approximate horizontal alignment with the lower end of said pump means and at an appreciable distance from said pump means. z v
Other objects may hereinafter a'ppear.
The accompanying drawings clearly illustrate the structure.
Fig.1, of the drawings is a side elevation of my device with portions of the structure cut away for clearness including a portion of the supply receptacle and shows in sec- I tion the with.
Fig. 2, is a perspective back end view of the device.
Fig. 3, isa detail plan View of the measure controlling member, detached.
pump mechanism associated there- Fig. 4, is an enlarged fragmentary po1-.-
- tion of the pump cylinder and shows thereinv a sectional detail of the pump piston and pump valve mechanism. r
The invention includes a supply receptacle for fumigating fluid, vertically disposed pump measuring and discharging means for measuring and discharging fluid from said receptacle and'vertically disposedlever actuating means for said pump means,
atomizing nozzle means and manually controlled check valve means associated with said nozzle means.
The device is illustrated in the presen preferred construction but it is to be understood that various mechanical alterations within the skill of the workmen may be The structureshown comprises a supply receptacle 1, for fumigating material. A pump cylinder 2 connected at its upper open end to the bottom of receptacle 1 and at its lower end to a base 3. A pump piston 4 working in the cylinder 2 is stopped by the shouldef 4 A piston rod\5 actuating the piston 4 and valve 6 extends upwardly from said piston. and through a vent dome 7 and packing gland 8 provided at the top of receptacle 1 and connects at its upper end to a yoke 9. -Connecting rodsA, A attached to the outer ends of yoke 9 extend down wardly and connect to cranks B, B the same being attached to shaft 10 having a pivotal bearing 11 the same being attached to base 3. Lever 12, -which is secured to shaft 10,
side of receptacle 1 to base 3 and is secured thereto.
Supporting member 16 which is secured at its lower end to base 3 projects upwardly and around one side ofreceptacle 1 and at its upper endsupports one end of a handle 17 for carrying the device. Suports 15 and 16 are clamped to receptacle 1 y tie rods 0, G. Fluid discharge line 18 having the valve 19 is connected at one end to the lower end of pump cylinder 2 and projects laterally therefrom and at its other end connects with atomizing nozzle means 20. A manually controlled check valve 21 flow of fluid through the nozzle and to aid 1 1,538,855 PATENT OFFICE...
the'pump action is connected to anactuating extension 22 which extends through a packing gland 23 to a connecting member 24 which is pivotally connected to crank 25, said actuating extension extending through said member 24 and slidably fitted therein is 'providedwith 'a compensating spring 26 and adjustment 27. Adjusting screws 28 and 29 are provided for the measure'controlling member 13. Vent line 30 connected at its upper end to vent dome 7 projects downwardly to a point in substantial horizontal alignment with discharge line 18 and thence laterally to a point adjacent the nozzle means 20. A glass tube 3l is provided for determining the quantity of fluid in supply receptacle 1. a A filler port' 32 hav ing the cap 33 is provided in the dome 7. In
a device of this character it is essential to build a structure of extreme lightness consistent with durability and in order to obtain such structure aluminum is extensively used even in the receptacle and as it is at present deemed most practicable to weld the seams therein it is important, due to the expense of said welding tolimit the structure to as few welds as possible, hence the packing gland casting I prefer to construct to include the vent dome and filler port. With this structure one weld serves for three purposes, namely; vent dome, packing gland and filler port.
,Due to the corrosive character of the fumigant of common use I prefer to .use special packing means in the pump piston, this packing comprises an expanding metal ring 34. and two expanding metal rings D, D on either side'of an asbestos fabric packing 35,
all within a. groove 36 as shown in Fig. 4.]
With such corrosive fumigant the pump cylinder and plston rings are apt to 'score or become roughened, hence the said fabricpacking, preferably asbestos, is employed to insure a perfect piston seal, and the rings D, D function to preventparticles of said packing from working out past the piston and into the said atomizing nozzle and clogging the same. Individual ring grooves may sired. v
, In operating the device the measurement of fluid is accomplished with a uniform stroke of the lever 12 controlled by the member 13 a full stroke accomplishing the measurement of five'units, the measurement of one unit being accomplished by springing the lever '12 to the right so it will engage with the screw 29. For example, if a measurement of eleven units were desired the operator would draw the lever 12 backward until it engaged with the screw'28, the movement units and it would then require the employment of the means provided for the measurement of one unit to accomplish the measurement of eleven units. Other measurements of different denominations would be accomplished in the same manner using the one unit measure when the five units could be provided for the rings D, D if de- The valve 21 by checksions from the pump means through the nozzle means. The nozzle check valve 21 is connected'with' the pump actuating means by the extension 22 and connection 24 and closes simultaneously with the full forward .stroke of the lever 12 but remains closed during the backward stroke of lever 12; during the backward stroke the member 2 1 slides on the valve actuating extension 22 and, continues to slide until lever 12 has completed the backward stroke and a forward stroke when, the member 2% engages with spring 26 closing the valve 2l,'tl1e valve having been opened by liquid pressure from the pump through line 18 and port 37, on the forward stroke of the lever. Adjusting means 27 is provided on the extension 22 back of spring 26 for accurate timing of valve 21. Since the piston 4 stops on the shoulder 4 simultaneously with the closing .of valve 21 I prefer to employ the compensating spring 26.
In my patent of Feb. 20, 1923, No. 1,446,- 093 I. show vertical lever means in a device of this character with a horizontal pump cylinder and in my patent of Dec. 11, 1923, No. 1,477,125 I show horizontal lever means with a vertical pump cylinder and in the device described herein I have combined the advantages of-a vertical lever with the advantages of a vertical cylinder and have also adapted my device to the use of a positive, 1
acting manually operated nozzle check valve. Having thus described my invention I claim:
1. A portable fumigating a plicator a-dapted to be carried by hand, inc uding a supply receptacle for fumigating fluid, base means,
supporting means attached to said base means, vertically disposed pump measuring and discharging means for measuring and discharging said fluid from said receptacle the measurement thereof representing a plurality of units, vertically disposed lever means for actuating said pum means said lever being supported by sai supporting means, a measure controlling member for controlling the said lever means and for de* termining the unitmeasurement of the said measuring means, atomizing nozzle means laterally spaced from the said pump means, and fluid conductingmeans for connecting said nozzle means with said pump means, and a positive acting manually operated valve means associated with said nozzle mean and co-operating with said lever and pump means, said valve adapted to control the free flow of fluid through the said nozzle means.
