UNITED STATES PATENT OFFICE.
FRED W. AUGUTT, OF MILLWOOD, WASHINGTON, ASSIGNOR TO INLAND EMPIRE PAPER 60., OF MILLWOOD, WASHINGTON, A CORPORATION OF WASHINGTON.
DRIER FOR PAPER MACHINES.
Application filed March 21, 1924. Serial No. 700,899.
To aZZ whom it may concern:
Be it known that I, FRED W. Ar ow, a citizen of the United States, and a resident of Millwood, in the county of Spokane and State of \Vashington, have invented a new,
and Improved Drier for Paper Machines, of which the following is a full, clear, and
exact description.
This invention relates to driers for paper machines and has for an object to provide an improved construction wherein great efficiency is secured by the more efficient removal of the water of condensation.
Another object is to provide a siphon for the removal of the water of condensation from cylinder driers wherein a flexible intake end is provided capable of automatic adjustment and movement to cause a maximum efficiency in the removal of water during the operation of the drier.
A further object is to provide a siphon structure for the removal of the water of condensation from drier cylinders which may be readily inserted through the journal of the cylinder.
In the accompanying drawing- The figure is a longitudinal vertical sectional view through part of a drier with. an embodiment of the invention applied thereto.
Referring to the accompanying drawing by numerals, 1 indicates the drier cylinder which is of any usual or preferred structure used in paper making machinery to dry the paper as the paper is moved along. As is well known, a number of these driers are used in a single machine and are heated by steam injected into the cylinders interiorly sothat the heat units may pass through the cylinders into the paper and the water of condensation caused to drop to the lowermost point in the cylinders unless carried around by centrifugal action. Heretofore, siphon devices, as well as certain other devices,'have been provided which have accomplished the desired result more or less efficiently, according to the adjustment of the parts and other surrounding devices. However, in many instances, the siphon's have been broken off or otherwise caused to operate with small efiiciency. It is also to be noted that if an appreciable amount of water is left in the drier, it is difficult for the heat units to pass therethrough and act on the paper passing over the drier.
To maintain the drier as freeof water as possible, a siphon pipe 2 is provided which is connected to the fitting 3, which fitting is also connected with the pipe 4 whereby suction may be provided from any suitable source. Connected with the inner end of the pipe 2, is a flexible hose 5 preferably of metal, welded or otherwise secured to the pipe 2 and also welded or otherwise secured to the nipple 6, which nipple may be of a special construction or an ordinary short section of pipeadapted to be supported near the lowest point of the cylinder 1. By this construction and arrangement, the drier is kept almost entirely free of water. In constructing the siphon pipe 2, the same is provided with a bend 7, but this bend is sufficiently short to permit the pipe 2 to be readily inserted through the opening 8 in the journal member 9 or to permit the pipe to be removed therefrom without removing the end 10 or without anyone using the usual .hand opening or manhole in the end 10. If the curved end 7 extended down- Wardly to near the lowest point of the'cylinder, it would be necessary to insert the pipe 2 through the manhole in the end 10 when the same is first placed in position and to remove the same in the. same manner. By providing the flexible section 5 and the short bend or end 7, these parts may be readily inserted through theopening 8 or may be readily removed therefrom. A
During the use of the drier, sometimes the parts become somewhat loose and sometimes the pipe2will sag downwardly. When this occurs, the nipple 6 will merely drag along the cylinder without doing any harm while functioning properly. Also a wearing sleeve 11 is'secured to pipe 2 by a set screw or other means and rests on the end 10 approximately at point 12. By providing this wearing sleeve, the pipe 2 will continue to function and at some convenient time a new pipe 2 placed in position and the parts again 100 set to their original position as shown in the accompanying drawing.
What I claim is:
1. The combination with a paper drying I machine having a hollow drying cylinder 105 into id y n er, and a i le u u ar member extending from the inner end of said pipe toward the inner surface of said cylinder.
2. The combination with a drier for paper machines, of means for removing the water of condensation therefrom, said means including a pipe extending through one end of the channel member of the drier and downwardly to a point spaced from the lowermost point of the drier, and a flexible pipe connected to the lower end of the first mentioned pipe and extending downwardly so as to engage the drier whereby when the first mentioned pipe is open, substantially all of the water of condensation will flow out of the drier and the drier maintained substantially free of water during its operation.
3. The combination with a drier formed with a cylindrical body, and a journal member, of a pipe extending through said journal member, a flexible hose secured to the inner end of said pipe and extendingto near the lowermost point of the cylinder, and a nipple connected with said hose and positioned normally in engagement with the inner surface of the cylinder whereby when said pipe is open the water of condensation in the drier will be maintained at a minimum.
4. The combination with a steam heated drier, of means for removing the water of condensation from the drier substantially as fast as it is produced, said means including a pipe extending through the journal of the drier, a flexible metallic hose secured at one end to said pipe and extending toward the inner surface of the drier, and\a tubular member secured to the free end of the hose positioned with its lower end near the surface of the drier continually whereby when said pipe is open water may flow from a point very near the lowermost point of the interior surface of the drier.
5. In a drier for paper machines, means for removing the water of condensation from the drier, said means including a siphon pipe formed with a short bend whereby the pipe may be inserted into position through the journal of the drier, and flexible means extending downward from said end to a point near the cylinder of the drier.
6. In a drier for paper machines formed with a cylinder having a journal with a longitudinal bore extending therethrough, of a siphon member formed from a straight pipe having a bent end, said end and pipe being insertable through said bore, a wearing sleeve connected with said pipe, and tubular means connected with said pipe at the inner end, said tubular means extending to a position near the lowermost point of the cylinder.
