BLOWER FOR OIL BURNERS Filed June 19, 1940 INVENTOR JOSEPH A. DEL/A BY 4 ATTORNEY Patented Apr. '13, 1943 UNITED STATES PATENT OFFICE BLOWER FOR OIL BURNERS Joseph A. DElia, Bridgeport, Conn. Application June 19; 1940, Serial No. 341,353
4 Claims.
This invention relates to new and useful improvements in blowers for oil burners.
The objects and advantages of the invention will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing wherein a satisfactory embodiment of the invention is shown. However, it is to be understood that the invention is not limited to the details disclosed but includes all such variations and modifications as fall within the spirit of the invention and the scope of the app nded claims.
In the drawing:
I Fig. 1 is a view taken as looking from the left in Fig. 2 and with parts broken away;
Fig; 2 is a side elevational View, with parts brokenaway, showing the burner; and
Fig. 3 is an elevational view showingan adjusting knob.
Referring in detail to the drawing the'burner here shown is of the gun type and the same includes any suitable base III on which is disposed a blower tube I l which may include an extension 12 secured in place as by bolts l3. Electrodes l4 extend through the tube and fuel oil is supplied to a nozzle (not shown) at the forward end of the tube as through a pipe l5.
Formed with or mounted on the blower tube H is a fan casing or housing It in which is mounted a fan I? driven by a motor l8 which also preferably drives the pump H). A portion of a transformer is shown at 29.
Air is supplied to the fan I! as through an intake 2| and is discharged by the fan into the blower tube H through a passageway 22. Heretofore efforts have been made in the direction of controlling the amount of air admitted to the fan and such structures resulted in the use of several different sizes of fans for the several different sizes or capacities of burners. According to the present invention a wall 23 partly separates the fan chamber from the interior of the tube II and extends fromv the front wall 24 of the fan or blower casing but stops short of the rear wall 25 thereof. As here shown the partition 23 is integral with the housing or casing IE but this is not an essential feature.
Extending between and having bearing in the casing walls 24 and 25 is a rod 25 having a threaded portion 2?. This rod may at one end be headed over a washer 23 and threaded onto the other end of said rod at the outer side of the casing wall 25 is an adjusting knob 29. forward face such knob is cut away and a lock nut also threaded on the rod 23 enters such In its recess in the knob 29 and is tightened against the same so that the knob may be used to rotate the rod 26 but is not turnable thereon.
Disposed on the upper side of the rod is a valve or plate 3| having lugs 32 and 33 through which the rod passes. Actually the rod is free in the lug 32 but has threaded engagement with the lug 33. Plate or valve :31 is of a length slightly greater than the distance between the free edge of the partition 23 and the inner surface of the rear casing wall 25. Thus by manipulating the adjusting knob 29 the rod 26 may be rotated and since it has'threaded engagement with the lug 33 but is held against longitudinal movement the valve 3! may be adjusted in the direction of the length of the rod by such rotating of the latter. Actually the valve 3| is adjustable between a position completely closing the passage 22 anda position wherein such passage iswide open. If desired knob. 29 may be provided with an arrow 34 and the descriptive words as shown in Fig. 3 to assist an operator in making proper adjustment of the valve.
' With the described construction it will be apparent that there is no interference with or attempt made to control the air supply to the fan [1. However, the valve 3| and the means of manipulating the same provides minutely adjustable means for controlling the discharge from the fan. When an installation is being made the valve is adjusted until the desired flame is obtained and thereafter the valve should not be further adjusted.
With this arrangement controlling the discharge of the fan into the blower tube I am enabled with one size of burner to accomplish the functions which previously required the use of three sizes of burners. There is always a full head of air available since there is no interference with the supply of air to the fan and the discharge of air from the fan can be very carefully regulated to that required for any particular fire.
Having thus set forth the nature of my invention what I claim is:
1. In an oil burner, a blower tube open at its upper side toward its rear end, a fan casing on the upper open side of said tube and including side walls and front and rear end walls, said rear end wall of the fan casing located adjacent the rear end wall of the blower tube, a fan in said casing, said casing having an air inlet, a bottom wall connected with the front end of the fan casing and extending rearwardly therefrom below the fan and closing off communication between the forward lower portion of said casing and said tube but stopping short of the rear end Wall of said casing to provide a discharge opening from the rear portion of the casing into the upper side of the tube toward the rear end thereof, a rod spanning said discharge opening, said rod mounted by the end walls of the casing for turning movement about the longitudinal axis of the rod, a fiat plate-like valve at one side of said rod and parallel therewith and extending between the side walls of said casing for sliding movement forwardly and rearwardly in overlapping relation with said bottom wall, said valve of a length and width to completely close said discharge opening between the rear end of said bottom wall and the rear wall of said casing, said valve having engagement with said casing whereby the valve is held against turning movement about said rod, a lug on said valve and through which said rod passes, and said rod having threaded engagement with said lugwhereby on turning of the rod about its longitudinal axis the valve is slid lengthwise longitudinally ofthe blower tube to vary the size of said discharge opening with the smallest size of said opening beginning at the rear wall of the casing and toward the rear end of the tube.
2. In an oil burner, a blower tube, a fan casing at one side of said tube and including side walls and front and rear end walls, said rear end wall of the fan casing adjacent the rear end of the blower tube, a fan in said casing, said casing having an air inlet, a bottom wall connected with the front wall of the fan casing and extending rearwardly therefrom below the fan and closing off communication between the forward portion of the fan casing and the tube but stopping short of the rear end wall of the casing to'providea discharge opening from the rear portion of the fan easing into the side of the tube toward the rear end thereof, a rod spanning said discharge opening opening and mounted for turning movement about its own longitudinal axis, a plate-like valve extending between the side walls of the casing for sliding movement forwardly and rearwardly in overlapping relation with said bottom wall, means holding said valve against turning movement with and about said rod, and a threaded connection between the valve and rod whereby on turning of the rod about its longitudinal axis the valve is slid longitudinally of the rod relative to said bottom wall to vary the size of the discharge opening from the fan easing into the blower tube with the smallest size of said opening beginning at the rear wall of the casing.
3. In an oil burner, a blower tube, a fan casing at one side of said tube and including side walls and front and-rear end walls, said rear wall of the casing adjacent the rear end of the blower tube, a fan in said casing, said casing having an air inlet, a bottom wall connected with the front portion of the fan casing and extending rearwardly therefrom and closing off communication between the forward portion of the fan casing and the tube but stopping short of the rear end wall of thecasing to provide a discharge opening from the rear portion of the fan easing into the side of the tube toward the rear end of the latter, a valve extending between the side walls of the discharge opening, means mounting said valve for sliding movement only forwardly and rearwardly in overlapping relation to said bottom wall, and means operable from the exterior of said burner to adjust said valve in overlapping relation with said bottom wall to further open or to further close said discharge opening.
4. In an oil burner, a blower tube having an intake opening at one side adjacent its rear end, a fan casing on said tube at said end and including side and end walls and having a discharge opening aligned with the intake opening of the tube, a plate-like slide valve, means mounting said valve for sliding movement forwardly and rearwardly in directions longitudinally of the blower tube across said intake and discharge openings to vary their effective area, and means operable from the exterior of said casing and tube for adjusting said valve forwardly and rearwardly longitudinally of the blower tube.
