SPECIFICATION forming part of Letters Patent N o. 740,650, dated October 6, 1903.
` Application led May .19 lil-Q13.' Serial No. 157,826. (No model.)
State of New York, have invented certain new and useful Improvements in Smoke-Machines,
of which the following is a speciiication. y
This invention relates to a device for generating smoke and forcing it into a system ofv pipes for the purpose of detecting and locating any leaks in the saine.v Smoke being very penetrating will when forced into pipes under a small pressure issue from any open- A ing, however small, and from this a leak in the pipes can be easily located.
The device consists of an inclosin'g case,y preferably of metal and rectangular in form.v
In the lower part of this case is a fire-box and in -the upper part a reservoir containing waf ter. Located in this reservoir and partially immersed in the water is a cap or cover, whichY may be made of copper to prevent its corrosion by the water and is preferably cylindrical in form and pivoted at its ends to allow of its being oscillated, as will be hereinafter described. This cover is open on one side; but Whenin position and hung onits pivots this opening is closed by the Water,V
ous ow of smoke from the machine as the cover is oseillated.
The operation of this machine is more fully l explained hereinafter and shown in the accompany-ing drawings. 1
Figure 1 represents a general elevation ofV a device embodying my invention, showingA ing-pipes 9', 10, and ll.
a removable perforated grate 2. This lireybox is separated from the Water-reservoir in the upper part of the case at the partition 3.
A cap or cover is Vshown'at 4 in its preferred y form,which is cylindricahand divided th rough the center by a partition 5 and pivoted on a shaft 6. This cover is cut away at the under side, as shown in Figs. 2 and 3,- and is immersed in the water contained in the reservoir deep enough to close this opening, thus forming two smoke-chambers in the inclosed space on either side of the partition 5. This cover is oscillated Yback and fort-l1 by means of a handle 7, and as the Water maintains a eonstantlevel, as shown at 8, the smoke-chambers are alternatelyincreased and decreased in size, thus forming a suction to draw the smoke from the tire-box through the connect- The pipes l0 and ll lare provided at their upper ends with a iiat hinged cap, suehas 12, which forms a valve ,upwardly opening, which allows the smoke to pass out as the cover 4 is oscillated, but prevents its passing back on the return stroke.. These caps are provided with a hooked hinge to permit their removal for cleaning or adjusting, thus forming a valve of simple construction and improved'form.
At 13 and 14 are shown outlet passages or pipes which are provided with check-valves,
which may be of any approved form and` which act oppositely to the corresponding valves at the upper end of pipes 10 and ll. These outlet- pipes 13 and 14 are joined to gether at l5 by au ordinary T connection `which is provided with a coupling-tail for con nection to the pipes or drains to be tested.
The operation of the machine is as follows: Having started a thick re with greasy waste kor other material in the fire-box, which will generate a dense smoke, the cover 4 is oscillated back and forth. 0n the upward stroke the smoke is drawn n p by the suction through the inlet-pipes 9 and l0 into the smoke-chamber and on the return strokeis forcedthrough the outlet-pipes 14 and l5 to the exhaust connection. At the same time the reverse operation is taking place iny the opposite smokechamber. It is thus seen that the smoke will issue in a continuous stream from the ex# haust connection to the pipes being tested,
ICO
which Yhave previously been connected to the.
lets closed.
The shaft 6, upon which the cover 4t is hinged, is held in a U-shaped support 16 at its ends, which allows of its being easily removed and also will allow it to rise as the pressure increases in the pipes under test and so acts as a safety device to prevent the seals of the traps from being forced by too great a pressure. As smoke is ver)T penetrating, any leaks in the pipes can be easily detected and located. The cover remaining floating indicates that there are no leaks in the pipes. If the pipes leak, the cover will slowly descend, and the speed with which it falls will indicate the extent of the leak.
It will be evident that many changes in detail of construction may be made in this device without departing from the scope of my invention, and I do not confine myself to the exact construction shown, as it is intended as an illustration of a preferred form.
1. Asmoke-machine comprising in its construction an inclosing case, a [ire-box, a waier-reservoir, a smoke-chamber of variable size, a passage connecting said smoke-chamber and said firebox, means for varying the size of said smokechamber for the purpose of drawing the smoke into and forcing the same out of the chamber and an outlet from said smoke-chamber to an exhaust connection.
2. The combination in asinoke-ma'chine of an inclosing case, a fire-box, 'a water-reservoir, a pair of smoke-chambers variable in size, passages connecting said smoke-chambers with said dre-box, means for varying the size of said smoke-chambers for the purpose of drawing the smoke into and forcing the same out of the chambers and an outlet from said smoke-chambers to an exhaust connection.
l 3. In a smoke-machine, the combination of an inclosing case, a lire-box, a reservoir containing water which closes one side ofa smokechamber partly immersed therein, a smokechamber variable in size, means for varying the size of said smoke-chamber by im mersing the same in water for the purpose of drawing the smoke into and forcing the same out of the chamber, a passage connecting said smoke-chamber and said fire-box, and an outlet from said smoke-chamber to an exhaust connection.
4. In a smoke-machine, the combination of `an inclosing case, a fire-box, a reservoir containing water which closes one side of each of a pair of smoke-chambers partly immersed therein, a pair of smoke-chambers variable in size, means for varying the size of said smoke-chambers by immersing the same in water, a passage connecting said smoke-chambers with said re-box, and an outlet from said smoke-chambers to a common exhaust connection.
5. In a smoke-machine, the combination of an inclosing case, a tire-box, a reservoir containing water which closes one side of each of a pair of smoke-chambers partlyimmersed therein, a pair of oscillating smokechambers, variable in size, a reciprocating cover coacting with the water to vary the size of said smoke-chambers, passages connecting said smoke-chambers with said fire-box, and an outlet from said smoke-chambers to a common exhaust connection. A
6. In a smoke-machine, the combination of a metallic inclosing,r case, a fire-box located in the lower part of said case, a removable perforated grate forming the bottom of the firebox, a water-reservoir located above said [irebox and forming the upper portion of the inclosing case, an inclosing cap immersed in the water and forming a smokechamber, a passage connecting said smoke-chamber and fire-box, and an outlet from said smoke-chamber to an exhaust connection.
7. In a sn1oke-machine,the combination of a fire-box, a smoke-chamber, a smoke-pipe connecting said smoke-chamber and said firebox, an upwardly-opening cap at one end of said pipe removably pivoted at one'side by means of a hooked hinge and forminga checkvalve for said smoke-pipe.
