SPRAYING- DEVICE.

To all whom it may concern Be it known that we, HERBERT DANIELSEN, FREDERICK A. HAAsE, Jr., and JOHN H. B. SHANNON, citizens of the United States, and residents of Newark, in the county of Essex and State of New Jersey, have invented a certain new and useful Improvement in Spraying Devices, of which the following is a specification.

The present invention has for its object an automatic disinfecting apparatus which is simple of construction and positive in action, and consists of an atomizer, together with an automatically operated reciprocating air or other gas pump having a relatively quick compression stroke and a relatively slow return stroke for intermittently and at regular intervals creating a momentary blast of air, said air blast being led to the atomizer. Means are also provided for varying the timing of the return stroke and at the same time maintaining the pressure of the blast constant, thereby varying the frequency of the intermittent blast.

Figure 1 is a front elevation of the apparatus with its cover removed. Fig. 2 is a sectional side elevation, the section being, taken along the line 33, whlch shows the pump in half section.

In the figures like numerals designate corresponding parts.

In Figs. 1 and 2, the numeral 1 designates a box or case having a cover 2, Fig. 2, said case 1 being so constructed that it will contain and support the other parts of the apparatus. The pump casing 5 is supported by means of the brackets 6 and 7 which are fastened to the back of the case 1 by means of the screws 8. The solenoid cylinders 9 and 9, on which are wrapped the coils 13 and 13', are supported by the insulating blocks 10 and 10, 11 and 11'. A means of support for the blocks 10 and 10, 11 and 11 is formed by cutting grooves in the rear and side walls of the case 1 into which the blocks 10 and 10, 11 and 11 fit and are fastened by means of the screws 12. To the bottom of the insulating blocks 10 and 10 are fas tened, by means of the screws 14, the binding posts 15, 16 17 and 18, which hold the wires 19, 20 and 21, which will be described hereinafter.

Specification of Letters Patent.

Application filed June 4, 1913.

Patented May 19, 1914. Serial No. 771,609.

The solenoid cores 22 and 22 have an upward and downward motion through the cylinders 9 and 9' as the current is respectively made and broken by means of the switch described hereinafter. These solenoid cores 22 and 22 are flanged near their ends, as shown at 23 and 23, and are fastened substantially to the cross-member 24 by means of the nuts 25. At the center of the cross-beam 2 1, is fastened the piston rod 27, being held in place by means of a screwfastening 28, which is attached to the crossbeam 2 1 by means of the screws 29. At the other end of the piston rod 27 is a shoulder 30 which supports the rubber plungers 31 and 31, that are held to the rod by means of the nuts 32.

At the end of the pump case or cylinder 5 is secured the plug 33, which contains the outlet tube 3 1, and the intake plug 4:. The intake plug 4 has cut in it a V-shaped slit 38, through which air is admitted to the cylinder 5 on the intake or return stroke of the pump, which is effected by gravity as will be more fully described hereinafter. As the intake plug 4 is screwed farther and farther down into the end plug 33, less and less of the V-shaped slit will be exposed above the surface of the plug 33, and smaller and smaller will become the opening through which the air is admitted to the cylinder 5. Thus by screwing the intake plug 4: into or out of the end plug 83 we have a means for regulating the speed with which air enters the pump cylinder 5 on the intake or return stroke of the piston, so that the duration of the intake or return stroke which is accomplished by the falling of the cores 22 and 22, is either quickened or prolonged by screwing the intake plug 1 respectively into or out of the end plug 33.

The atomizer 37 shown in Figs. 1 and 2 is of the type in which air passing through a tube which leads from the pump cylinder 5, is blown across the end of a tube which leads from the reservoir of the atomizer thus causing a vacuum to be formed and inducing a stream of liquid to flow, which, when it meets the blast of air in an external nozzle 39 in Fig. 1, is broken up and blown outward into a fine spray which is excellent fol-disinfecting purposes: But the particular pattern or character of the atomizer forms no essential part of my invention. The atomizer is supported by means of a block 32, which fits into grooves in the rear and side walls of the casing 1 and is fastened by means of the screws 12. The bottle or reservoir of the atomizer is held in place on the block 32 by means of the spring 40, which 44 isof suitable form to hold the carbon.

47, which is fastened to the switch plate 44 by bending the sides of the plate "in, as "best shown in Fig. 2. The upper carbon contact piece 48 is held in a similar mannera-s 47 by the upper switch contact piece plate '49, which ls-screwed to thelink 50 by means of the screws 51. The said upper switchplate 49 is in the form ofa spring so that whenthe switch is closed it willpress its carbon contact piece 48 against the lower contact piece 47 sufficiently to form a good electric contact.

The link 50 is made of a suitable insulatin'g material and issupport'ed on a pin 52 which is driven through the link 50 and which is held in 'the'bearing brackets 53, as 'shownin Fig. 2, the saidbearing brackets 53 being fastened to the rear 'wallof the case 1 by ine-ans of screws 8. The link rod 54 which has an eye at'each'end is fastened by means of pins 55 and 56 to the ends of the aforesaid link 50 and a link '57. The link 57 fastenedat its other end to a bearing bracket 58 by means of a pin 59 in amanrner similar to which the link .50 is fastened to the bearing bracket 53. The bearing bracket 58 is fastenedto the rear wall-of the case 1 by means of the screws- 8. The aforesaid li'n'k'57 has a cross-bar 61, shown best in Fig. 1, to which are fastened the springs 60. The other end of the said springs 60 are held by eyes 62,.Fig. 2. To the cross-rod 24 is fastened-by means ofthe screws 63 a plate 64 which pushes against link 57 when tlTQ'SOlGIIOIdS are raised and starts the link 57 onits upward motion; which, when it has sufficiently passed its dead center, with respect .to the springs 60, will continue to move upw-ard'by virtue of the elasticity of the springs 60 until'it comes in contact with the rubber bumper 65 which is held by the bracketti.

In the operation of our device current enters through the fuse box 66 and is led along-the insulated wire 19 to the binding post 15, from which it is carried around through the coil 13 to the binding post 16,. through the insulated wire 20 to the binding post 17 then around through the coil 13, from here to the binding post 18, then through the insulated wire 21 to the upper switch plate, and hence to the upper carbon contact piece 48. The circuit is completed when the switch is closed, bringing the upper contact point 48 and the lower. contact point 47 together and permitting the current to flow out through the binding post 46 through the wire 67, through the fuse and hence back into the main line.

Supposing the switch to be closed, the: current passes through the solenoid cores. 13 and 13, thereby quickly drawing up into the cylinders Sand 9 the cores 22 and 22 and imparting a relatively quick compression stroke to the piston r0d27. As the cores rise they carry with them the cross-bar 24 which, as the cores near the top :of their stroke, raises the link '57 by means of the plate 64, pushing it sufficiently so that it is carried farther by means of the springs 60, as heretofore described. As the link 57 moves upward around its pin 59 it drags with it. the link 54, which in turn raises the lever 50 upward around. its pin 52,thereby opening the switch and thus cutting off the current. the cores 22 and 22 reced'e' from the coils 1.3 and 13, due to the force of gravity, carrying the piston rod 27 down with a relatively slow return stroke,and :whenthey reach the end of their downward stroke they again close the switch, since the cross-bar 24 "to which they are attached then" rests on the link 50-and the weight ofthe cores is suflicient to overcome the; tension ofthe springs 60. As soonas the switch is closed, current passes through the solenoid coils, the cores are raised, and when they reachthe end of their upward stroke they again *open .the' switch, as before described, and thus the cycle goes on repeating itself. The raising of the solenoid cores gives compression stroke to pump which furnishes air to the atomizer. The intake or return stroke vof the pump, the duration of which can be regulated by means of the p1ug4, as heretofore described, serves not only to bring sufficient air into the pump c'ylinder5 but by retarding the fall of the solenoid cores serves to regulate the frequency-ofthe discharges of disinfecting fluid fromtheatomizer. The variation in frequency of the blast, as above' described, nevertheless maintains the pressure'ofthe blast constant.

What is claimed, is:

1. A spraying device comprising an atomizer, an automatically operated reciproeating air pump having a relatively quick compression stroke and a relatively slow return stroke for intermittently and 'at'regw' As soon as the current is shut off lar intervals creating a momentary blast of air, and means for leading said blast of air to the atomizer- 2. A spraying device comprising: an atomizer, an automatically operated reciprocating air pump having a relatively quick compression stroke and a relatively slow return stroke for intermittently and at regular intervals creating a momentary blast of air, means for varying the timing of the return stroke and at the same time maintaining the pressure of the blast constant, thereby vary ing the frequency of the intern'littont blast, and means for leading said blast of air to the atomizer.
