UNITED STATES PATENT OFFICE.

ANDREV FERRARI, OF GLASSBOROUGH, NEW JERSEY, ASSIGNOR TO THE -WHITNEY GLASS NVORKS, OF SAME PLACE.

GLASS-ANNEALING OVEN.

SPECIFICATION forming part of Letters Patent No. 430,937, dated J' une 24, 1890.

Application filed December 7, 1889. Serial 110.332,89?. (No model.)

To all whom it may concern.-

Be it known that I, ANDREW FERRARI, a citizen of the United States, residing at Glassborough, in the county of Gloucester and State of New Jersey, have invented a new and useful Improvement in Glass-Anneali`ng Ovens, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to a glass-annealing oven; and it consists in the construction and arrangement of the parts thereof, as will be more fully hereinafter described, and pointed out in the claims.

Figure l represents a transverse vertical section on line as at, Fig. 2, of a glass-annealing oven embodying my invention. Fig. 2 represents a longitudinal vertical section thereof on line y y, Fig. l. Fig. 3 represents a horizontal section thereof on line e' .2, partly broken away, Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, AB O designate a number of glass-annealing ovens having necks D, connecting the bottoms thereof.

E designates a horizontal flue, which eX- tends under the floor of each oven and through each neck D, thus making the iiue continuous. tical iue F, which opens at the top into said chamber and at the bottom into the flue E.

G G designate vertical fines, which are formed in the base of the central oven B and adjacent necks D, the same being in communication with the flue E, and also with a supplemental flue H, which is below the central portion of said iiue E.

In the flue E, below the oven B and adjacent to the necks D, are dampers J K, and in the flues G G are dampers L and M.

Each stack N has a damper P, and each oven has a burner Q for introducing hydrocarbon vapor or other liquid fuel into the oven, it being noticed that each oven has a pile R of fire-brick or other refractory material, against which the ignited vapor is directed for diffusing said vapor and distributing the heat in the ovens.

lVhen the burner of ovenA is in operation,

rthe burners of the other ovens are closed.

The heat in the oven A, after effecting its work therein, enters as waste heat the flue F At the back of each chamber is a ver-- and descends to the liuc E. It will be noticed that the dampers J K are closed, the

dampers L M opened, and the dampers of the stacks of the ovens A B closed. The waste heat traverses the portion of the flue E beneath the oven A, descends the iiue G, passes through the flue H, rises in the flue G", and thus reaches the portion of the iiueE below the oven C, after which it enters the ue F of said oven O and is directed by the same into said oven O, where it is eifective for heating the latter, and is thereby utilized, it finally escaping through the stack of said oven C.

It is evident that by proper manipulation of the dampers the waste heat from the ovens B and O may be directed into either of the other ovens, so that effective work may be performed, it also being seen that the sides and bottoms of the ovens may be heated by the waste heat and either oven primarily prepared for its work by the introduction of such heat thereinto, thus utilizing the saine instead of directly passing it off, which, as is evident, is a loss. Y

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a glass-annealing. furnace, a series of ovens having burners andl communicating one with the other at the lower portions thereof by means of flues E and separated by double walls, with a'space between the same, said flues E having dampers therein, the lues G, G', and H below the flues E, and the dampers L M, controlling communication of the iiues G G respectively, with the flues E, whereby the waste heat from one oven may be conveyed to another oven, substantially as described.

2. Glass-annealing ovens with communieating fiues E under the oors of said ovens, in combination with the flues F at the back of each oven, the flue I-I below flues E, the flues G G', connecting said flues H and E, the stacks N, the dampers .I K in the Hue E, the dampers L M in the flues G G', and the dampers P in the stacks N, substantially as described.
