`Be itlrnown that I, I-IARRY B. EAGER, a y
citizen of the United States, residing at,
South. Bend, in the county of St.Joseph ,and
D `stovepipecouplings, designed particularly to effectively connect the 'meeting or lapped ends of'stovepipe-sections.
n ,The main object of'theinvention is production of a coupling of this 'class which isreadily locked in position andisreadily disengaged when desired, the construction ,being such as to avoid anyprojectingparts lwliich'would tend `to interfere with the movement ofthe pipe in placing it in position. i
' The invention will be described in detail; in the following specification, with particular reference to the accompanying drawings, whichf z Figure 1 represents aview elevation showing my improved coupling yapplied to the meeting ends of two stovepipe-sections. Fig. 2 is a longitudinal sectionon the line 2 2 of Fig. 1. Fig. 3 is a transverse section on the line 3 3 of Fig. 1. Fig. 4 is a perspective view of one member of the lock, and Fig. 5 is a perspective view of the other member of the lock. y
Referring particularly to the drawings, 1 1v represent.stovepipe-sections designed to be coupled together, each section near its coupled end being circumferentially beaded, as at 2. v
My improved coupling comprises a split band 3, having circumferential edge beads 4, so positionedi that when the band is in place upon the meeting ends of the sections 1 the beads 4 will interiorly receive or register with the beads 2 on said sections. Adjacent the transverse division in the band I secure my lock, comprising two members 5 and 6, each of plate-lil e formation and designed to be permanently secured to the band 3. The
vmember 5, formed, preferably, of thin metal,
is T=shaped and secured to the band 3 by rivets 7, passing through the arms'thereof.
The elongated or central portion of the member is provided with a series of projecting teeth 8, which teeth are formed to have one surface 9 at right angles to the surface of the member 5 to provide for positive engagement therewith of the other member 6. The member 5 is curved in longitudinal section Y l aboutL coincident the pipe-sections landis so attached to the-.bend 3 that its lower freeend ,will project beyond .band and p overlie the vband :beyond said division. The other member 6, 1' also of. v.T-
. v shaped form, is'fsecuredto thezband-B on .the
opposite side of the division thereof! :from member 5, rivets 10 securing thismember in place.- The upper or -free end off this A,member is tur-ned `downwardly at an acute -'angle to the plane of the( membertoj provide a lip or .tooth y1.1, designedto engage the teethy8gon the member .5. O nthe inneror lower side the toothll forms anacute angle with thebedy of the member 6,-as at 12, whereby said tooth 11 is designedgto fully` andcompletelyengage the right-angle surface 9 ofthe teeth 8. The
member 6 is provided with ,`the;..concaved aper tures.,1.4 are arranged'. to .be. ,exposedbe one or the: other ofthe. shoulderszlS, the shoulders being concaved to prevent the lateral displacement of the said pointed instrument.
plied over one end of the pipe-sections 1 and the end of the adj oinin pipe-section is slipped into the opposite end of the band until the beads 4 of the band engage the beads 2 on the sections. By small pressure the meeting endsof the band are brought together and the tooth 11 caused to engage one of the teeth 8 of the member 5, it being understood that the pointed instrument is inserted in one of the apertures 14 behind one or the other ner of a crowbar until the toothll engages that particular tooth 8, which will snugly bind the band about the ends of the sections 1, whereby said sections are effectively coupled and prevented from accidental separa-` tion. By having the 'members 5 and 6 slightly curved to conform with the curvature of the pipe-sections I avoid any projecting parts of the section which would tend to interfere with any necessary movement of the completed pipe. It is evident that any particular band is adapted for coupling various size pipes, being limited only by the number of teeth 8, as the coupling is efficient as a securing medium by the engagement of tooth 11 with any of the teeth 8.
Although I have shown and described the coupling as particularly designed for connectthe ,junction or transverseV divisionfofthe' Shoulders 1,3, to beengagedby apointedinfg strument, such as, a nailv or-file point: The
In the use of my device the band 3 is apof the shoulders 13 and operated in the man- IOO ing stovepipe-sections, other uses thereof will be obvious and are contemplated by this invention.
Having thus described the invention, what is claimed as new is- 1. A pipe-coupling comprising a divided band, and a lock secured thereto said lock comprising two members respectively secured t0 the band on opposite sides of the division thereof, one of said members being formed With a plurality of teeth and a plurality of apertures; and the other of said members being formed with a single tooth adapted to engage with any of the teeth of the first-mentioned member and with concaved shoulders, said apertures in the first-mentioned member, and the concaved shoulders in the second-mentioned member adapted to be engaged by a pointed instrument to effect the engagement of said members.
2. A pipe-coupling comprising a divided band, a locking means secured thereto, said locking means comprising two members respectively secured to the band on opposite sides of the division thereof, one of said members having a series of teeth, and a plurality of apertures arranged on opposite sides of said series, the other of said members being provided with a single tooth adapted to engage any one of the teeth of said series and with concaved shoulders, the apertures of said first-mentioned member and the shoulders of the second-mentioned member being adapted to be engaged by an instrument to effect the engagement of said members.
3. A pipeecoupling comprising a divided band, and a lock secured thereto, said lock comprising two members respectively secured to the band on opposite sides of the division thereof, one of said members bein@ provided with a tooth and an aperture, andJ the other of said members being provided with a single tooth arranged to engage with the tooth of the first-mentioned member and with a shoulder, the aperture of said iirsternentioned member and the shoulder of the secondementioned member being adapted to be engaged by an instrument to effect the engagement of said members.
4. A pipe-coupling comprising a divided band, a lock secured thereto, said lock comprising two members respectively secured t0 the band on opposite sides of the division thereof, and adapted to have an interlocking engagement, one of said members being provided with an aperture and the other of said members being provided with a shoulder, said aperture and shoulder being adapted to be engaged by an instrument to eifect the looking engagement of said members.
In testimony whereof I aHiX my signature in presence of two witnesses.
