REMOVABLE PARTITIGN FOR METAL-HEATING FURNACES.

Application filed October 3, 1919. Serial No. 328,163.

T 0 all whom it may concern:

Be it known that I, RICHARD .G. DRINKER, a citizen of the United States, residing at Quincy, county of Norfolk, and State of Massachusetts, have invented certain new and useful Improvements in Removable Partitions for Metal f Heating Furnaces, fully described and represented in the following specification and the accompanying drawings, forminga part of the same. 7

This invention relates to a partition which maybe inserted removably in the heatingchamber of a metal heatin -furnace to subdivide the space into convenient compartmentswhich can be'heated and used separately when the furnace is not wholly required for heating long articles.

Such partitions are shown in application l lo/321,126 filed September 2, 1919 for patent on open side furnace; and the present invention relates to a particularconstruction for the partition by which it is provided with detachable foot-plates to support it upon runways when the partition 'isin use, and which may be stored separately and far more compactly by separation from the partition when it is not in use.

The invention includes'various details of construction, which will be understood .by reference to the annexed drawing, in which Figure 1 is an elevation of a furnace with two partitions therein dividing it into three separate spaces, the .door in; front of two such spaces being raised or elevated to expose the interior to view; Fig. 2 is a cross section of the furnace adjacent to ,a.partition supported on foot-plates the door of the chamber being raised; Fig. "3 is a plan of the parts shown in Fig. 4 in section on line -33 in Fig. 1; Fig- 4 is aside elevation of the frame for one of the partitions mounted upon three detachable foot-plates; Fig. 5 is an end elevation of the parts shown in Fig. 4; Fig. 6 is a cross section of the frame f t e p r ion ken en n 5-6 n Fig- 7 is an n er ed plan ef h etpl tes s own en th the pa t n-fram Fie- 4 and Fieis an ge view of one of as fe t-plate p e a g S le h n Fig. l.

nace which is of much greater width than length. Z) designates the partitions mounted upright upon foot-plates which are supported upon rows of balls .(Z guided in runways 6 upon the floor. 7

The two partitions divide the heatingchamber a into three spaces which are provided with separatedoors f, f. and f The doors f and f are shown raised in Figs. land 2. f

A combustion-chamber g is shown beneath the heating-chamber in Fig. Q'but' forms no part of the present invention, as it is immaterial to this inventionhow the heatingchamber is heated.

Each partition is formed of a castemetal frame having a web it at the middleof its thickness with flanges i projecting squarely from the web to both sides of'theipartit-ion.

The flanges cross the facesof the partition dividing it into various spaces in which the TED STATE-S rnrnnrorrron. I

fire-brick or filler can be retained, whichis essential to preserve the partition from destruction in theheating-chamber.

The web is formed with apertures j which connect the corresponding spaces 'upon .opposite sides of the web, and' permit fire.- bricks or filler is to be extended through the apertures, as shown in Fig. 6, to lock together the refractory coating upon the'opposite sides of the partition, by engagement with bricks is which are -laid directly against'the web h..

When all the spaces are filled with bricks,

the partition is protected sufficiently for of the partition. A rib Z performs the same function upon the foot-plate.

A narrow rib is employedto facilitate the pp ng eff o he i i nec s y to make,

lie plate at having parallel ball raees pon thenndere de to lfit two rows of balls 91, which are movable in runways 11 upon the floor. Such runways extend transversely across the heating-chamber, and outside of the same far enough to draw the partition wholly from the chamber, when it .can beremoved and stored until needed be fitted for again supporting the partition by simply placing three of them contiguous over the runways supported: upon theballs therei11.,To prevent. the passage of gases between the ends of the truck, a tongue 39 is formed upon one end of'each and a notch 9 upon the opposite end, such tongues and notches interlocking when the foot-plates are placed in proximity. r

It is understood that such trucks are adapted only to move in a straight line and to form a straight row when assembled, such as is shown in Fig. 7, adapted to receive and transport the partition I). I

In the lower corners of the partition recesses' s are shown with'transverse pin 11 in each, and such pins are provided to engage the oppositeends of a chain or sling; which would be hung from a crane and extended over'the upper corners of the partition to such pin for lifting'and moving the partition.

l-lolesr are shown perforating the frame near the middle of the topwhich may be used for a similar purpose.

"It is evident that a single foot-plate of suitable length could be used if constructed to receive 'and center the partition thereon the same as aplurality of foot-plates; but the plurality is preferable because it makes. each part lighter for handling.

This is a material advantage, as suclrpartitions are not in use all the time and take less room when stored if mounted detach ably upon the foot-plates and if the foot plates themselves are relatively small so as to be moved with facility.

By the construction shown, the entire foot-plate consists of a single casting having parallel ball-races upon its under side, and a suitable seat upon the upper side to receive and hold a partition.

RA recess in the foot-plate to guide the setting of the partition thereon is shown in the drawing formed by ridges 0 running along the edges of the foot-plate over the ball-races; but any other means may be employed to form a loose detachableengage- Provision is also shown in Figs. 3 and 4: I

to prevent the passage of gases past the rear edge of the partition and serving at the same time to'steady the partition and hold it upright.

This provision consists of a vertical groove or recess a formed in the rear wall of the furnace into which the rear edge of the partition is pushed when it is inserted in the heating-chamber, and which embraces its edges or corners with sufficient snugness to hold the partition steady-andprevent the passage of gases. i V

A plurality of trucks is desirable to support the partition so as to permit of the expansion of this supporting member.

Such expansion is permitted by placing the trucks with an open clearance between their adjacent ends, and the passage of gases between the severaltrucks is prevented by the interengagement of the tongues 10 and notches '9 upon the adjacent ends of the trucks.

It will be readily understood that a footplate greater in width than the thickness of the partition is necessary to sustain it upon the balls in the runways nfland if such foot-plate were integral with the partition it would prevent the piling of the partitions with their sides in close contact when not in use in the heating-chamber. i p

The foot-plate shown herein is not adapted for any other purpose except to support the partition while in use in the furnace, and is therefore difierent from ordinary trucks which may be used to carry miscellaneous articles. I I i foot-plate shown herein is one of the elements which operates to entirely close the space between separate compartments of the" furnace, and has the rib Z projected from its lower-side for the express purpose of preventing the passage of gas beneath the partitiom v j i Having thus set forth the nature of the invention what is claimed herein is: V

1. In a metal-heating furnace having runways extended transversely of the heating-chamber, foot-plates. having ball-races corresponding to the runways and seats in alinement upon the tops of the foot-plate,

and a partition fitted to the seats upon the runways and supported thereby in working 7 position within the heating-chamber.

2. In a metal-heating furnace having runways extended transversely of the heat ing-chamber, a partition provided with a plurality of means for supporting it movably upon the runways such means having recesses in alinement with one another upon their upper sides adapted to "receive and center the partition and being detachable from the partition when removed from the heating-chamber for storage.

3. In a metal-heating furnace having runways extended transversely of the heat ingchamber, a partition provided with plurality of interlocking detachable footplates for supporting it movably upon the runways, such foot-plates having recesses in alinement with one another upon the upper sides adapted to receive and center the partition, and ribs upon their under sides to prevent the passage of gases.

l. In a metal-heating furnace having runways extended transversely of the heating-chamber, a partition provided with means for supporting it movably upon the runways and the rear wall of the furnace having a vertical recess adapted to receive the rear edge of the partition when pushed thereinto and to then retain the partition in a vertical position.

5. A removable partition for a metal heating-furnace, comprising a frame having a central web with flanges projected squarely therefrom at the edges and across its flat sides, and apertures through the-web between the crossed flanges for binding together the refractory material upon the opposite sides of the web.

6. A removable partition for a metal heating-furnace, comprising a frame having a central web with flanges projected squarely therefrom at the edges and across its sides the frames thickness corresponding to the length of a fire-brick, apertures through the web between the crossed flanges, and fire-brick extended transversely through the apertures for binding together the refractory material upon the opposite sides of the web. a I

7 A removable partition for a metal heatingfurnace, comprising a recessed frame having its recesses filled with refractory material and sockets in the ends of the frame with transverse pins fitted to engage means for lifting the frame from the truck when required.

In testimony whereof I havehereunto set my hand.

RICHARD G. DRINKER.
