1 Claim. (Cl. 158-2) This invention relates to a heating apparatus and more particularly to a new and useful mounting for an oil burner assembly.

One object of this invention is to provide an oil burner mounting that suspends the burner assembly from the vertical wall of the heating apparatus.

Another object is to provide a mounting that reduces the transmission of both noise and vibration of the oil burner assembly to the heating apparatus.

Another object is to provide a novel mounting which permits a relatively easy removal of the oil burner apparatus from the heating apparatus without the removal of bolts or the like.

Another object of this invention is to provide a mount-.

ing that is rugged in construction, economical to manufacture, and easy to assemble.

Other objects of the invention will become apparent from the following description, the drawings to which it relates and the claim hereinafter set forth.

This invention comprises the new and improved construction and combination of parts and their operating relation to each other which will be more fully described hereinafter, and the novelty of which will be particularly pointed out and distinctly claimed.

In the accompanying drawings, to be taken as part of the specification, there is fully and clearly shown a preferred embodiment of this invention, in which drawmgs:

Figure 1 is a view in side elevation and partly in section of a portion of an oil burner assembly and a heating apparatus showing the mounting means of this invention.

Figure 2 is afront elevation of the oil burner assembly with the hanger assembly of the mounting means secured thereto.

Figure 3 is a front elevation of part of the vertical wall of the heating apparatus having the supporting member of the mounting means and which receives the hanger assembly secured thereto.

Referring to the drawings by numerals of reference and particularly to Figure 1, there is shown an oil burner comprising an assembly 1. The oil burner assembly 1 has a motor 2, a transformer 3, an oil pump 4, and a blower assembly 5. The blower assembly 5 has a blower housing 6 with a front wall 7. The blower housing front wall 7 has a plurality of apertures 7 therein. Secured to the blower housing front Wall 7 is a blast tube 8. The blast tube 8 contains the oil spray nozzle and an oil igniter which are not shown. The blast tube 8 has flange ears 8 secured to the blower housing front wall 7 by a plurality of bolts 9 having heads 9. The heretofore described oil burner assembly is a conventional gun type burner that is well known in the art.

In Figure 1 there is shown in section a portion of the vertical wall 10 of the heating apparatus which includes a casing surrounding the combustion chamber. The vertical wall 10 has an enlarged aperture 11 therein to permit passage of blast tube 8 therethrough. It should flange portion 19. The wall portions 18 lie against the blower housing front wall 7 and have apertures therein for the passage of supporting screws 20 therethrough.

The flange portions 19 are parallel and extend from the outer vertical edges of portions 18. Through the portions 19 in spaced relation to the portions 18, there are aligned apertures 21 to receive the opposite ends of a hanger shaft or rod 13. The hanger shaft 13 is secured in the apertures 21 in spaced parallel relation to the wall 7, thus forming the hanger assembly 16. The hanger assembly 16 is positioned on and secured to the burner housing front wall 7 by means of the screws 20 threaded into the apertures 7 in the blower housing front wall 7. Positioned above the wall opening 11 and secured to the outside of the heating apparatus wall 10 is a channel-shaped supporting member 22 which cooperates with the assembly 16. The supporting member 22 has an enlongated fiat portion or flange 23 and a curved channel-shaped portion 24. The supporting member 22 has its flange 23 secured to the heating apparatus vertical wall 10 by a plurality of screws 25.;

Although the supporting member 22 and the hanger assembly 16 are secured by means of screws, it should be understood that any conventional method of securing these members to their respective parts may be used. A pressure plate 26 is positioned adjacent the exterior side of the vertical wall 10 and has an aperture 27 therein. The aperture 27 is substantially the same diameter as the blast tube 8. Secured to the outer face of the pressure plate 26 are a pair of abutment members 30 preferably generally U-shaped having their end or bridging portions 30 spaced from plate 26. The abutment members 30 are positioned on opposite sides of the aperture 27 and are aligned with blast tube supporting bolt heads.

9 when the blast tube 8 is inserted in pressure plate aperture 27. The members 30 are so constructed that they extend a predetermined distance away from the pressure plate outer face. Positioned between the hanger shaft 13 and the supporting member channel portion 24 is a cushioning member 31 that functions as a vibration dampening means. Positioned on and secured to the end portions 30 of the pressure plate members 30 are cushioning members 32. The cushioning members 31 and 32 are preferably of asbestos cloth and are so positioned that there is no metal to metal contact between the oil burner assembly 1 and the heating apparatus vertical wall 10 or the pressure plate 26. Thus the blast tube bolt heads 9 rest against the cushioning members 32 on the pressure plate members 30, and the hanger shaft 13 rests against or on the cushioning means 31. Positioned between the pressure plate 26 and the vertical wall 10 is a fire resistant insulating means 33 preferably of asbestos cloth material having an aperture 33 therethrough alined with and smaller than the plate opening 27, so that the material is flexed and sleeves around the blast tube 8. The insulating means 33 is secured as by cementing to the plate 26 and serves a dual purpose. One purpose being a safety measure to prevent the heat transfer between the vertical wall of the heating apparatus and the pressure plate 26. Another purpose is to act as a cushioning or vibration dampening means. Thus metal to metal contact between the pressure plate 26 and the vertical wall 10 is eliminated. The cushioning members 31 and 32 also function in a similar manner to prevent heat transfer to adjacent metal parts.

As will be seen from the following description, the oil burner assembly 1 is suspended and supported on the vertical wall of the heating apparatus. The burner assembly is supported by means of the hanger shaft 13 being positioned in the channel portion 24 of the supporting member 22. When in operative position, the blast tube 8 passes through the aperture 27 in the pressure plate 26, and the aperture 11 in the vertical wall lnember 10. It should be noted that the hanger assembly 16 projects outwardly from the blower housing front wall 7, and the support member 22 projects outwardly from the vertical wall thus permitting the oil burner assembly 1 to be supported in a substantially horizontal position.

In positioning the oil burner 1, the pressure plate 26 is placed on the blast tube 8 with the blast tube 8 pass ing through

aperture

7 and 33 It should be noted that the insulating member 33 has the portion around its aperture 33 sleeved over the blast tube 8 to permit a secure fit and a more cfficient insulator. The blast tube 8 of the oil burner assembly 1 with the pressure plate 26 and insulating member 33 positioned thereon is then inserted into aperture 11 of the vertical wall 10. Since the diameter of the aperture 11 is substantially larger than the diameter of the blast tube 8, the oil burner assembly 1 may be moved vertically a sufiicient distance to permit the hanger assembly shaft 13 to pass over the channel portion 24 of the supporting member 22 and rest on the insulating material within the channel portion 24. The oil burner assembly 1 having its center of gravity eccentrically supported by or being offset from the hanger shaft 13 in the channel portion 24, it tends to rotate toward the wall 10 and in a counter-clockwise direction facing Fig. 1, so that the weight of the oil burner assembly 1 applies a pressure against the pressure plate 26 to hold it against the wall 10 by engagement of the bolt heads 9 with the cushioning members 32 on the abutment members 30.

The purpose of the cushioning members 31 and 32 and the member 33 is to prevent the transmission of noise and vibration from the oil burner assembly 1 to the heating apparatus vertical wall 10 and subsequently to the remaining portions of the heating apparatus and system. The cushioning members 31 and 32 are preferably formed of an asbestos tape cemented in their respective positions. It is to be understood that although an asbestos type of cushioning means is used in this disclosure, other suitable cushioning and insulating means could be substituted without departing from the scope of this invention. It has been found that the new and novel supporting and cushioning means as shown have materially reduced vibration and noise accompanying the operation of gun type oi'l burners.

While there has been only one embodiment of this invention illustrated and described, it will be obvious to the artisan that other embodiments are possible with out departing from the scope and intent of the invention which is to be limited only by the appended claim.

Having thus described the invention, what is claimed and is desired to be secured by Letters Patent of the A United States is:
