1 Claim. (Cl. 158-4) This invention relates to improvements in adjustable mountings for liquid or gaseous fuel burners of the character employed in glass furnaces and the like.

The invention has among its objects the provision of an improved and simplilied adjustable burner mounting structure, simple to construct, maintain and operate.

Additional objects and features of the invention will become apparent from the following description taken in connection with the accompanying drawings, in which:

Figure 1 is a broken, plan view of one embodiment of the burner mounting of this invention;

Figure 2 is a front elevation of the burner mounting illustrated in Figure 1;

, Figure 3 is a side elevation of the burner mounting illustrated in Figure l with the burner and the port wall of a furnace shown inrphantom;

Figure 4 is a plan view of another embodiment of the burner mounting of this invention; and

Figure 5 is a side elevation of the burner mounting illustrated in Figure 4.

Like reference characters are used to refer to like parts in the various figures.

' Referring to the drawings, and in particular to Figures l to 3, the burner mounting, generally identified as 10, comprises a base plate 11, connected in a 'suitable manner, as by bolting, to an angle 12 connected to the port wall 13 of a glass furnace 14. The base plate 11 is substantially triangular in plan having an arcuate side 15 with a protuberance 16 extending therefrom. The pretuberance 16 is provided with a central aperture 17, and the plate 1v1l is provided with a slot 18, the'purpose. of -both to be described.

An angular adjustment carriage 19 is attached by a bolt 20 and a nut 21 to the base plate 11 for limited angular sliding movement relative to the base plate 11, and comprises a substantially triangular plate 22, L- shaped toe guide and

stop plates

23, 24 connected to one side of the plate 22, a pair of spaced,

upstanding guide rods

25, 25 connected to the plate 22, an opening 26 evenly spaced between the

rods

25, 25, and a nut 27 welded to the plate 22 over the opening 26. A pivot mounting plate 28 having a central opening 29 is connected to plate 24, as illustrated. The toe guide and

stop plates

23, 24 are arranged for cooperation with the arcuate side 15 of the plate 11 and guide the plate 22 relative to the plate 11, and also act as stop means to limit the movement of the plate 22 relative to the plate l1 by engagement with the protuberance 16.

A pivot member 36 comprising a substantially rectangular plate 31 having a threaded central opening 32 and a depending threaded rod portion 33 is rotatably secured to the protuberance 16 by means of a nut 34 engaging the threaded portion 33 which passes through the aperture 17. A pivot member 35 comprising a substantially rectangular plate 36 having a central opening 37 and a depending threaded rod portion 38 is rotatably secured to the pivot mounting plate 28 by means of a nut arent r if@ 39 engaging the threaded portion 38 which passes through the opening 29.

An angular adjustment screw 40 is threadably received within the opening 32 in the plate 31 and is provided with a reduced, threaded, terminal portion passing through the opening 37 in the plate 36 to receive a nut 41 for connesting it to the plate. The screw 40 is also provided with a square terminal portion 42 adapted to receive a handwheel (not shown) for rotating the screw. R0tation of the screw 40, as is obvious, varies the position of the carriage 19 relative to the base plate 1l, which, as will be apparent as the description proceeds, will vary the angular relation of the carriage 19 to the furnace 14.

Avertical adjustment carriage 43 is associated with the angular adjustment carriage 19 and is vertically movable The carriage 43 comprises a carriage relative thereto. plate 44 having a pair of

openings

45, 45 adjacent its terminal ends, a pair `of

upstanding side plates

46, 46 and an apertured yoke 47 attached centrally to its bottom surface. A pair of

pipes

48, 48 are attached tothe bottom surface of the plate 44 with their openings coaxial with the openings 45, and are received in sliding relation around the rods 25 upstanding from the plate 22 of the angular adjustment carriage 19. A pair of

guide rods

49, 49 are connected adjacent the terminal ends of the

side plates

46, 46, the

rods

49, 49 being spaced above the plate 44, as illustrated, and one of the side plates 46 is provided with an opening 50 and has a nut 51 connected thereto coaxial with the opening S0.

' A vertical adjustment screw 52 is vthreadably received in the nut 27 attached to the angular adjustment carriage plate'22 and passes through the slot 18 inthe base plate 11. The screw 52 is provided with a reduced threadedv terminal end to receive a nut 53 by which it is attached l justment carriage 43 and comprises a split circular clamp 56 adapted to be tightened about a burner tube 57 reof pipesr, 60 connected to the clamp 56 and received,

for sliding movement over the

rods

49, 49 connected-to the

side plates

46, 46 of the carriage 43, and a depending centrally disposed plate 61 also connected to the clamp 56, the plate 61 having a central opening 62 therein.

A clamp carriage adjusting screw 63 is threadably received in the nut 51 connected to one of the side plates 46 of the carriage 43 and is connected at one terminal end to the plate 61 by means of a nut 64, a reduced portion of the screw 63 passing through the opening 62. The opposite terminal end of the screw 63 is provided with a square portion 65 to receive a handwheel (not shown) by which the screw 63 is rotated. Rotation of the screw 63 moves the carriage 55 to any position between the side plates 46 of the carriage 43, the carriage 55 being guided by means of the

rods

49, 49 and the pipes 60, 68.

Thus, in the embodiment illustrated in Figures 1 to 3, four adjustments of the position of the burner tube 57 may be made; namely, (l) that of the angular disposition of the burner relative to the port wall 13 by means of the angular adjustment carriage 19 through the operation of the screw 40, (2) that of the vertical disposition of the burner by means of the vertical adjustment carriage 43 through the operation of the screw 52, (3) that of the transverse disposition of the burner by means of the clamp carriage 55 through the operation of the Patented A131275 .1960
