LE GRAND, OF BALTIMORE, MARYLAND, ASSIGNOR TO CARRIER ENGINEER- ING- CORPORATION, A CORPORATION OF NEW YORK TAP Application filed June 8,
The object of my invention is the providing of an improved means for connecting exhaust pipes of dust or cleaning apparatus, especially of the portable type, to the permanent piping system established in a building.
A further object of my invention is the providing of a floor tap let into the floor flush, covered when not in use, easily openedand provided with means for securely and tightly holding a hose connection which is easily detachable therefrom.
A further object of my invention is the providing of a floor tap adapted for standard construction, and means for attaching the same to standard piping used in exhaust systems.
ii A further object of my invention'is the providing of an improved floortap that is durable and simple in construction, and convenient for receiving metal hose attachments.
With the foregoing andother objects in view, my invention consists of the novel construction, combination and arrangement of parts as hereinafter specifically described and illustrated in the accompanying drawings,
wherein is shown the preferred embodiment of my invention,'but it is understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.
In the drawings of the herein-described embodiment of my invention, Figure 1 is a plan view of my floor tap in position in the floor of a building, with its cover in place; Fig. 2 is-a view in elevation, partly in section, taken through 2-2 of Fig. 1, and Fig. 3 isa view in elevation partly in section showing the exhaust hose attachment plugged in.
Similar numerals refer to similar parts 4 throughout the several views.
1 is the floor casting, or shell, provided with a flange 2 for inserting in the floor, and provided with means for securing, such as screws 3, or other suitable means. 1 are lugs within shell 1 to sustain a cover when the tap is 1926. Serial No. 114,586.
closed and not in use. Cover 5 is provided with means for easily lifting the same, such as, sunken eye and ring 6.
7 is the pipe which is a part of the exhaust system to which the plug is to be attached, and is secured to projection 8, preferably to the exterior thereof, by means of soldering to make a tight joint; but any well known means may be used. Projection 8 is a continuation of the body or tap 9 within which body is formed tapered opening 10 into which a tapered attachment 15 secured to an exhaust hose 16 may be plugged in. 11 is the plug for closing opening 10 when the same is not in use, and consists of a plug properly fitted, preferably of the'character shown, to permit easy withdrawal. Plug 11 is provided with means for extraction consisting of ring 12, and to prevent the same from being misplaced ring 12'is provided with a securing chain 13 fastened at one end to ring 12 and atthe other end to eye 14 secured to shell 1. I have found that the standard Morse taper is verysuitable for the taper of the opening 10. I have also found "that ordinary brass gives satisfactory results in the construction of the various parts of my floor tap, including the cover and plug. The method of operating my floor plug is almost obvious. Cover 5 is first removed, plug 11 is pulledout and the hose attachment 15 inserted-in opening 10.
Having thus described my invention, what I claim and desire to secure by Letters Patent 1s:
1. An outlet for exhaust systems comprising a shell having an external peripheral flange at one end to enable the shell to be set approximately flush into a wall at the flanged end and also having a chamber opening outwardly through the flanged end and at its inner end restricted into a tapered passage tapering away from said chamber,said shell at its end opposite the flanged end being formed for attachment to an exhaust conduit, a movable closure mounted approximately flush in outer flanged end extending in a direction away from the flanged end for a material distance, and then having a converging passage leading from the inner end wall of said chamber, a closure received flush-in the outer end of said chamber, said shell having abutments in said chamber adjacent the outer end for limiting the inward movement of said closure, and a tapered plug separate from said closure and insertable and removable through said chamber at will while the cover remains in open position.
3. An outlet for exhaust systems comprising a shell having an external peripheral flange at one end by which the shell may be mounted approximately flush within a wall, and with the shell extending into the wall from the flanged end, the shell at its inner end being formed for connection to an exhaust conduit, said shell having a chamber in the outer flanged end extending in a direction away from the flanged end for a material distance, and then having a converging passage leading from the inner end wall of said chamber, a closure received flush in the outer end of said chamber, said shell having abutments in said chamber adjacent the outer end for limiting the inward movement of said closure, a tapered plug separate from said closure and insertable and removable through said chamber at will while the cover remains in open position, and a flexible connection between said shell at a point within said chamber and said plug whereby the plug may be removed or inserted freely, and when the plug is inclosed position, be entirely concealed within said chamber by said closure.
4. An outlet for exhaust systems comprising a. shell having an external peripheral flange at one end by which the shell may be mounted approximately flush within a wall, and with the'shell extending into the wall from the flanged end, the shell at its inner 'end being formed for connection to an exhaust conduit, said shell having a chamber in the outer flanged end extending in a direction away from the flanged end for a material distance, and then having a converging passage leading from the inner end wall of said chamber, a closure received flush in the outer end of said chamber, said shell having abutments in said chamber adjacent the outer end for-limiting the inward movement of said closure, and a tapered plug separate from said closure and insertable and removshell having a chamber extending in a direc- 4 tion-lengthwise thereof for a' material distance from the flanged end, and a converging tapered passage connecting the inner end of said chamber with the unflanged end of the shell, a closure for the outer end of said a chamber received in the open end thereof and approximately flush with the outer end face thereof, said shell having means within said chamber for limiting the inward movement of said closure, and a tapered plug fitting said tapered passage and insertable and removable at will while the closure remains in open osition.
6. An outlet or exhaust systems comprising a shell having an external peripheral flange at one end by which the shellmay be mounted in a wall with the flanged end approximately flush with an outer face of said wall, the other end of the shell being formed for attachment to an exhaust conduit, said shell having a chamber extending in a direcchamber for limiting the inward movement of said closure, a tapered plug fitting said ta pered passage and insertable and removable at will while the closure remains in open position, and means within said chamber for connecting said plug to said shell separately from said closure and concealed within said chamber by said closure when the latter is in closed position.
7. An outlet for exhaust systems comprising a shell having an external peripheral flange at one-end by which the shell may be mounted in a wall with the flanged end approximately flush with an outer face of said wall, the othei end of the shell being formed for attachment to an exhaust conduit, said shell having a chamber extending in a directance from the flanged end, and a convergin v tapered passage connectin the inner end 0 said chamber with the un anged end of the shell, a closure for the outer end of said ,chamber received in the open end thereof and approximately flush with the outer end Ill face thereof, said shell having means within said chamber for limiting the inward movement of said closure, and a tapered plug fitting said passage and having peripheral grooves in its tapered face for breaking up said face into a plurality of annular bands engaging with the wall of said passage, whereby said tapered passage may be efiectively closed by said plug without the plug being tightly wed ed therein.
