DRY STEAM SPRAYER Filed March 26, 1955 INVENTOR.
Jacob 56/7Wdff2 ATTORNEY- Patented Mar. 31, 1936 UNITED STATES.
PATENT OFFICE DRY STEAM SPRAYER- Jacob Schwartz, Brooklyn, N. Y.
Application March 26, 1935, Serial No. 13,108 17 Claims. (01. 299-149) The purpose of this invention is to improve devices for spraying dry steam by making it possible to provide complete control over the steam at the nozzle and by the hand in which the nozzle is held and also to provide a return adaptedto take all condensation away from the control valve.
The invention is a steam valve having a live steam connection passing straight through the upper part thereof with a condensation pocket extending downward therefrom and connected to a return so that condensation may pass directly into the return and also so that live steam may pass into the return as soon as the valve is closed. A handle is provided by which the valve may be held by hand and the valve is also formed with a lever at one side which is positioned so that the valve may be opened and closed by the thumb of the hand by which it is held.
Many other devices have been provided for this purpose but any of them do not provide a straight live-steam passage or a condensation pocket with a return connected in the pocket and arranged so that the live steam may pass into the return when the valve is closed. One device, in particular, is divided into two chambers with a valve between the chambers but condensation may collect in the chamber beyond the valve and this will be ejected with the spray as soon as the valve is opened. Other devices have been provided for draining ofi the condensation but in every instance it is possible for a small amount of condensation to collect in the valve when the valve is closed and it is desired to provide a valve of this type which will only spray dry steam and which will not spray or sp it water at any time during the operation thereof.
The object of the invention is, therefore, to
provide a device for spraying dry steam in which all danger of condensation being sprayed therefrom is eliminated. 7
Another object is to provide a dry steam spraying device. which has atendency to dry steam as the steam passes therethrough.
Another object is to provide a. dry steam spraying device which is provided with a return connection to which all condensation may pass and through which the steam may pass when the valve is closed so that continuous circulation of the steam is maintained with the valve opened or closed.
Another object is to provide a dry steam .spraying device in which the full control of the spray is at the point from which the steam is sprayed. I
Another object is to provide a dry steam spraying device in which the amount of steam being sprayed may be regulated at the spray and 5 this may be accomplished without danger of condensation accumulating therein.
A further object is to provide a dry steam spraying device which may be instantly shut off at the point from which the spray is ejected. 10
And a stillfurther object is to provide a dry steam spraying device having full control of the spray and in whichall danger of condensation is eliminated which is of a simple and economical construction. 15
With these ends in view the invention embodies a valve body with live steam and return connections at one end; a nozzle atthe other, a valve adjacent the nozzle and a lever adapted to operate the valve extending upward to a point 20 adjacent the end of a handle, by which it may be held. V
Other features and advantages of, the invention will appear from thefollowing description taken in connection with the drawing, wherein:, s
Figure l is a view showing a side elevation of the device with part broken away showing the return pipe connection.
Figure 2 is an end viewlooking toward the 0 nozzle or discharge end of the device.
Figure 3 is a plan View of the valve bodywith the lower part ofthe forward end of the handle shown in section and withparts omitted.
Figure {lis a detail showing a sectional plan 36 through the valve.
In the drawing the device is shown as it may be made wherein numeral l indicates the valve body, numeral 2 the valve member, and numera1 3 a handle by which the device may be held. 4
The valve body I is of a rectangular shape with the base sloping towardone side, however, it will be understood that the shape or. designof the body may be changed to accommodate different conditions or difierent methods of construction or difierent material of which the device may be made. In the design shown the valve body. ismade of acasting which is substantially hollow and in which numeral ,4 indicates the chamberon the interior, numeral 5 6 the back, and numeral 6 a discharge nipple to which'the nozzle 1 may beconnected. 4
A live steam supply connection is provided by a nipple 8 which is threaded into a boss" 9' at the'upper corner of the back 5 and this conin the boss I6.
nection opens into the interior chamber 4. A return connection is provided in the lower corner of the valve body and this is formed by a nipple I0 which is threaded into a boss II and on the inner end of the nipple I9 is a smaller nipple or bushing I2 which is threaded into the nipple I 0 and which extends into the chamber 4 to the point I3 so that all condensation accumulating in the lower part of the valve body will pass directly into the return through the nipples I2 and I0. It will be understood, however, that the nipple or bushing may be omitted so that the condensation will enter the nipple I9 direct, however this connection may be formed in any manner, or by any means.
The sides of the valve body are drawn together as shown at the point I4 in Figure 4 and this section of the valve body is provided with a boss I5 at one side and a corresponding boss I6 directly opposite and positioned on the other side. The nipple 6 extends outward from the opposite side of the bosses I5 and I6 and the nozzle I, which is formed of a short piece of tubing in which the outer end is flattened and the .inner end threaded into the nipple 3 as shown in Figures 1 and 4.
An opening I! is provided in the boss I5 and a bushing I8 is threaded into this opening as shown in Figure 4 with the valve member 2 slidably held in the bushing I8 and resiliently held against a valve seat I9 by a spring 20. The opening I I connects with the interior of the valve body I through a passage 2| and an opening 22 on the opposite side of the valve seat I9 connects with the interior of the nozzle I through a passage 23.
The valve member 2 is provided with a pin 24 that extends into an opening 25 in the boss I6 and contacts a head 26 on a pin 21 which is slidably mounted in a bushing 28 that is threaded The outer end of the bushing 28 is provided with a packing gland 29 that is threaded on a shank 30 extending from the outer end thereof.
The outer end of the pin 21 engages a lever 3I that is pivotally mounted between ears 32 on the lower side of the valve body by a pin 33 and the upper end of this lever extends upward so that it may be conveniently engaged by the thumb of a hand on the handle 3 and it will be noted that as the upper end of the lever is pressed inward it will move the pin 21 inward and this will move the valve member 2 away from the seat I9 through the pin 24 thereby opening the passage and permitting steam to pass from the interior "of the valve body through the passage 2I, the opening H, the valve seat I9, the opening 25, and the passage 23 to the nozzle I; and it will be noted that as soon as the lever 3| is released the spring 20 will force the valve member against the seat and close the passage thereby instantly shutting off the steam. The lever 3I is provided with a point 34 which engages the surface of the nipple 6, as shown in. Figure 2, to limit the outward movement thereof, and the spring 20 will hold the lever in this position, with the valve closed.
The handle 3 is attached to the upper end of a U-shaped frame 35 and the frame is provided with a base 36 that is attached to lugs 3'! and 38 on the upper side of the valve body by the bolts 39 and 40 as shown. It will be understood, however, that the handle may be of any other .type or design, may be arranged in any manner and may be attached to the valve by an; means.
It will be understood that changes may be made in the construction without departing from the spirit of the invention. One of which changes may be in the use of other means by which the device may be held by hand, another may be in the use of other means for connecting the live steam to the device, another may be in the use of other means for taking care of the return or condensation, and still another may be in the use of other means for operating the valve. v
The construction will be readily understood from the foregoing description. In use the valve may be provided as shown in Figure 1 and may be connected to live steam through the nipple 8 with the nipple I0 connected to a return, and with a nozzle I arranged as shown. The handle 3 may be gripped in the right hand and held so that the thumb may readily engage the upper end of the lever 3I. When it is desired to spray steam the lever may be pressed so that the valve will open and steam will pass through the device as hereinbefore. described. And it will be noted that the flow of steam may be readily controlled by the lever and the steam may be instantly shut off and also instantly turned on, and when the steam is turned off condensation does not accumulate in the valve body as all condensation passes immediately into the return through the connection into which the nipple I0 is connected. The device may therefore be readily used without danger of any water whatever being sprayed or discharged through the nozzle and the valve may be opened instantly the full amount, or to any amount desired so that any amount of steam may readily be sprayed.
