MICHEL G. FAGAN, OF TROY, NEW YORK.I ASSGNOR TO HIMSFALB AND ALBERT G'. CORSE; OF SAMEI PLACE.l
Letters Patent No. 112,233, dated February 28, 1871.
IMPROVEMENT IN HEATiNG APPARATUS.
The Schedule referred to in these Letters Patent and making part of the same.
To all 'whom 'it may concern:
Be it known that I, MICHEL G. Fnenmof Troy, in the county of Rensselaer and in the State of New York, have invented certain new and useful Improvements in Heating Apparatus; and do lierebydeclare that the following is a full, clear, and exact description thereof, reference being 'had to the accompanying drawing making a part of this specitication, in which- Figure 1 is a plan View of the upper side of a drum constructed in acc- 'dance with my improved method, and
Figure 2 is a vertical central .section of the same on the line :c x ot' fig. 1.
Lettersoi' like name and kind refer to like` parts in each of the figures,
As commonly constructed the drums or sections of heatingfurnaces above the i'nel-chamberare composed of sheet-iron Acylinders inclosed at either end by cast* iron plates resting upon or against the same, and the whole secured together by means of a number of bolts passing through both plates and the cylinder, and con- 'doing the latter between the former.
This construction is, however, open to serious cbjections, among which are--V First, the impossibility of making a` joint between the ends of the cylinder and the plates that shall retain a vsuliicient amount of cement to insure a gastight drum, and
Second, the unequal vertical expansion of the parts, by means of which, at certain temperatures, the bolts are slackened, so as not to confine said part-s closely together, while at other temperatures said bolts are subjected to a suicient' strain to occasionally cause them to break, and thereby derange the heating apparatus and render repairs necessary.
To obviate these diiculties is the design of my invention, which consists in the employment of castmetal rings fitted around or withinand secured to the ends of thecylinders, and combined with the end covers, substantially as and for the `purpose hereinafter shown.
In the annexed drawing- A and B represent the outer and inner cylinders, respectively, of a drum, corresponding in length and arranged concentrically.
' Secured to and around the upper end of the outerv cylinder A is a cast-metal ring, C, the outer edge of which coincides with that of said` cylinder, from whence it extends downward upon the same Ito a suliicient distance to permit of the insertion of rivets c, bolts, cr other equivalentflevices, by means of which said parts are attached together.
From its upper edge the ring C extends horizontally outward and then vertically upward, so as to form a right-angled rebate, D, within and upon which is placed the top plate E, which, ais seen in fig. 2, con` sists of a plane disk of cast metal, provided with a number of horizontally-projecting lugs, F, through which pass the bolts G, used for securing said plate to or upon said ring, the radial conformation of said rebate 1) being suited to the exterior shape of said plate with its lugs.
The ring C', attached to the upper end ofthe inner cylinder B, is constructed in a similar manner' to that before described of O,except that it h'ts within instead of around said cylinder, and projects inward instead of outward from the same.
As thus constructed a suitable layer of cement Vis spread upon the seat or horizontal portion of' each ring, and the top plate placed thereon, and secured tirlnly thereto by means of bolts passing through both puits The rings H and H,attached respectively to the lower ends 'of the outer and inner cylinders, are fitted to or upon the inside of the same, and from thence, extending horizontally outward or inward, are provided with lngs I, corresponding with those formingr 'l part of the top plate, but have no upward-projectlng ilunges.
The bottom plate K corresponds, in exterior siz and shape, with the top plate, but has, in addition, a ange, k, projecting upward from its outer edge, so as to embrace the edge ofthe ring'H, and a second iiange, L, projecting upward just outside of the inner cyliner B.
In attaching together the bottom plate anddrum the cement is spread upon the former, immediately beneath each ring, and is held in place by means of the vertical auges, If desired, in order to render more certain the closeness of joints, coment may be placed within the spaces left between `the cylinders and vertical flanges, at the lower end of the drum, and upon and around the inner and outer edges of the top plate', where, from the peculiar shape of the parts, said coulent will be securely held in place.
It will be seen tha'ain attaching the` bottom 'plate 'to the cylinders, it is necessary to form the seat for the. reception of the cement upon and to attach the upward-projecting danges to said plate, instead of the ring, as before; but asthis arrangement of parts is just the reverse of that employed at the upper end of thedrum, it is considered only a necessary modification of the same.
The drum above described is intended for use in n hot-air furnace, where it would be placed' above tho fuel-chamber, and connected therewith by means of one or more pipes vopenin` from 'the upper end of said chamber into 'the space between-tho cylinders end the ltmp and bottom plates, so 's to conse the heated escaping products of combustion to pass through the same and into an exit-pipe passing outward through the side or from the top of said drum, and thereby imparting a portion of their heut to the air surrounding the latter. v This device is, however, only shown for the purpose of illustrating my invention, which, as will be readily seen, is equally4 applicable toeny portions of heating apparatus where it is desired to formar permanent joint' between the end of a sheet-metal section or' cylinder and a enst-metal cover.
v The especial advantages possessed by this construction of e. drum are-'- Y l First, the joint at either end independent of and cannot be affected bythe expansion or contraotion of other parts ot' the device, and, being made with very short bolts, is not liable to de rangement from or by changes of temperature.
Second, each joint is horizontal, and no change of temperature or ordinaryl use of the lle-sing apparatus can in any manner loosenor remove the cement, so that, it'well made originally, said joints are certain to continue gestight 'while the metal remains intaot.
