J OININ G MEANS.

Application filed. July 2,

The present invention relates to joining means, such as bands or rings for joining or connecting sections of a heater or the like.

Among the objects of the invention is to provide a novel joining band structure adapted to fit sections of different sizes with out the necessity of carrying different sized bands in stock, but which can be made with the major or main part of the hand of a size to fit the smallest heater section and adapted to receive a connected'segment to enlarge the band to the larger sizes of sec tions to be fitted or joined. thus requiring the carrying in stock of only the small segments instead of whole bands of different sizes. i

a The invention also comprehends the provision ,of novel means for connecting the ends of a band or of the'band and the seg-- ments.

Other objects, advantages, capabilities and features are comprehended bythe invention as will later appear and are inherently possessed thereby.

Referring to the drawings, Fig. 1 is a perspective view of a heater or furnace using bands constructed in accordance with the invent-ion.

Fig. 2 is a fragmentary sectional view. through a part of the sect-ions of a heater and a band in place.

-Fig. 3 ,is a horizontal sectional through apart of the band.

Fig. 4 is a perspective view of a band slgowing the construction of the ends there- 0 Fig. 5 is a fragmentary perspective view of partly connected ends of the band or an end of a band with an end of a segment.

Fig. 6 is a similar viewv of the. connection shown completed And, Fig. 7 is a view in spaced assembly and perspective showing the relation of the endsof a band and an interposed segment. before connection thereof to the ends of the band.

Referring now, more in particular to the drawings, the embodiment selected to illustrate the invention is shown asv in the form of a band having a. main portion 1 preferably of cylindrical form and parted in .a plane passing through the axis of the band. the band comprising an intermediate channel portion'2 which acts as a support or separating member between the sections 8 view 1926. Serial N0. 120,036.

and i and 3 and 5 ofa furnace or heater, and appearing as a rib atthe exterior of the heater as clearly shown in Figs. 1 and 2 of the drawings. WVhen in position in the heater, the flanged portions 6 and 7 of the band are located interiorly of the sections of the heater and engaging the interior sides thereof, the inherent resiliency of the band causing the flanges of the band to constantly press against the inner surface of the seotio'ns. The rib or channel portion 2 will eX- tend outwardly so that the lower end of a section, such-as the lower end 8 will rest up on the top face 9 of the rib 2 and the upper end 10 of the lower section will contact with and support the lower face 11 of the rib 2,

" as clearly shown in Fig. 2 of the drawings.

The main or major portion of the band is provided with ends 12 and 13 of which the former is preferably provided with apertures 14 formed in the flange portions 6 and 7, and also with adjacent depressed or chan n'eled portions 15 preferably located adjacent to the apertures 14., and the other'end 13 being preferably formed with integral tongues or projections 16 extending circumferentially from the ends of the flanged portions 6 and 7, as clearly shown in Fig. a of the drawings. The tongues 16 are preferably curved as more clearly shown in Fig. 4 of the drawings, for facilitating the entry of the ends of the tongues into the apertures 14. j

When applying the band to a, furnacehaving sections of the smallest size, it is not necessary to use an interposed segment, but the tongues 16 can be directly connected to the other end of the band by the insertion of the ends 17 of the tongues through the apertures 14 so that the body portion of the tongues will fit into the depressed portions 15. and then the ends 17 of the tongues may 1 lie laterally bent as shown in Fig. 5 of the drawings, and then hammered over to form the hooked portions 17 as shown in Fig. 6 of the drawings, these hooked portions thus clasping the inner surface of the depressed portions 15 whereby the connection cannot be readily disengaged.

In the event of using the bands in a furnace having sections of larger size, the band may be expanded to form a gap be tween the ends of the band and a segment 18 may be used to fill this gap. The segment 18is preferably provided with flange the band desired to fit the particular size of sections of the heater.

The opposite ends of the segments are provided with connecting means respectlvely the same as at the endsof the major portion of the band, one end being provided with apertures 14 and depressed portions 15 adapted to be connected with the tongues 16 of the band in exactly the same manner as previously described when the parts 14 and 15 of the band were connected. The other end of the section has tongues 16 with ends 17 of the tongues curved to enter into the apertures 14 and channel or depressed portions 15 of the adjacent end of the band body portion. 1 g

It will be apparent from Fig. 7 of the drawings that the tongues at the right hand end of the segment 18 will. enter into and be connected to the end of the main part of theband shown at the right hand side of the segment, and that the tongues 16 on the otherend of the main portion of the band and shown at the left hand side of the segment 18 may enter into and be connected to the left hand end. of said segment, as shown in said figure. The ends of the tongues may be bent over into the form of a hook in the manner above described in connection with Figs. 5 and 6 of the drawings.

While I have herein described and upon the drawings shown a particular embodiment of the invention, it is to be understood that the latter is not limited thereto but comprehends other constructions, details, features and arrangements of parts without departingfrom the spirit thereof.

Having thus disclosed the invention, I claim: e I I 1. A joining means, comprising a band of circumferential form and having mutually engageable abutting ends. one of said ends having an aperture and a depressed portion. the other of said ends having a tongue adapted to fit into said depressed portion and extend through said aperture.

2. A joining means, comprising a band of circumferential form and having mutually engageable abutting ends, one of said ends having an aperture and a depressed portion, the other of said ends having a tongue adapted to fit into said depressed portion and extend through said aperture. the projecting end portion of said tongue beingadapted to be bent to form a hook clasping said depressed portion.

A joining means. comprising a band portion and a rib portion both of circumferential form and parted in an axial plane, and means at the ends of said band portion for mutually connecting said ends together 41. A connecting means for joining bands,

comprising end portions of a band adapted to be connected together in abutting relation, one of said end portions having an aperture, and a depressed portion adjacent said aperture, the other of said end portions having a projection adapted to extend through said aperture and to fit into-said depressed portion, the end of said projection being adapt, ed to be bent to form a hood to clasp said depressed portion.
