3 Claims.

The present invention relates to new and useful improvements in siphons generally and more particularly to a device of this character for use in the drying cylinders of papier-mach machines.

6 An important factor in the manufacture of paper is the process of drying the paper after it has been formed into a fibrous web by the machine, commonly known as wet end" machine. This is done by running the paper over cylinders of comparatively large size known as dryers, said dryers, in most cases, being steam heated.

The steam is admitted to the driers through hollow journals. As the steam gives up latent heat to heat the driers, which, in turn, dries the paper or fibrous web on the outside thereof, the steam condenses and forms a body of water inside the drying cylinder.

Continuously operating means must be provided to remove this water from the dryer cylinders in order to keep the body of water to a minimum so that a maximum portion of the inside of the driers is at all times exposed to the live steam, resulting in hotter driers and a saving of steam.

This process of removing water is made possible by the use of siphon pipes which siphon the water from the driers assisted by the steam pressure. Many difficulties have been encountered in the installation of siphons and in the operation thereof after installation in order to secure satisfactory results and the primary object of the present invention is to provide, in a manner as hereinafter set forth, a siphon embodying a novel construction, combination and arrangement of parts through the medium of which the same may be expeditiously and conveniently installed for operation in a drying cylinder utilizing steam as the heating medium.

Other objects of the invention are to provide a siphon of the character described which will be simple in construction, strong, durable, highly eflicient and reliable in use and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference desig- 50 nate corresponding parts throughout the several views, and wherein:

Figure 1 is a view in,vertical section through an end portion of a drying cylinder showing, in side elevation, a siphon in accordance with the present invention in operative position.

Figure 2 is a view in top plan showing the hinge joint of the siphon.

Figure 3 is a view in side elevation of the siphon showing the same being installed in the drying cylinder.

Figure 4 is a view principally in vertical longi tudinal section through the hinge joint.

Referring now to the drawings in detail, it will be seen that the reference letter A designates a portion of a steam drier cylinder having projecting longitudinally therefrom a hollow journal B.

The remaining end portion of the elbow 1 is internally threaded, as indicated at l2, (see Figure 4) for the reception of an arcuate pipe l3 which, when in operative position, extends to substantially the lowermost point in the drier, as shown in Figure 1 of the drawings. The free or intake end of the arcuate pipe i3 is provided with notches H to prevent said pipe from being closed should it engage the drier I. The pipe l3 may be of a suitable curvature to permit the same to be inserted into the drier and withdrawn through the hollow journal 2, or, if desired, said pipe I 3 may be straight.

It is believed that the many advantages of a siphon constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of 'the invention as claimed.

The embodiment of the siphon constituting the present invention which is illustrated in the drawings comprises a pipe i which extends centrally through the Journal 2 into the drying cylinder I Threaded on the inner end of the pipe I is a collar 2 which projects longitudinally inward from the pipe and which is provided with a bore 3 of a diameter corresponding to the interior diameter of the pipe I. The inner end of the collar 2 is provided with an external flange 4.

An annulus 5 is mounted on the collar 2 in abutting engagement with the flange 4. Projecting axially inwardly from one side portion of the inward end of the annulus 5 is an armcfi having a transverse opening in its free end portion. The

reference numeral I designates an elbow which is mounted for swinging movement in a vertical plane on the arm 6 through the medium of the upstanding, apertured ears 8 which rise from said elbow and a pivot pin 9 extending through the opening in the arm 6 and the apertures in the ears 8.

The elbow 1 is operatively engageable by gravity with the collar 2 in a manner to provide a substantially leak-proof joint and to this end said elbow is provided with a convex, smooth end portion ll which is engageable in a seat which is defined by a concavity Ii provided in the inner end portion of the collar 2, said concavity mergmg with the bore 8 ol the collar. I derstood that when the convex end of the elbow seats within the concave seat ll of the collar member 2, the elbow will be limited against further downward movement, and direct communication between the bore of the collar 2 and the passage in the elbow is established.

What is claimed 'is:

l. A drier roll having a supporting journal provided with a horizontal passage of restricted diameter. and, in combination therewith, a siphon pipe assembly adapted for entry through said passage and for removal therefrom, said assembly comprising a supporting pipe portion extending horizontally through said passage, a pipe extension within the drier 'roll depending angularly downwardly from the end of said pipe portion, interconnected attachment members on the adjacent ends of said pipe portion and said pipe extension, said attachment members having engageable seat portions normally providing a substantially fluid-tight connection and maintained in seating engagement merely by the weight of the extension pipe and its connected attachment member, said attachment members having inter- ,engaging portions aflordlng upward movement of the pipe extension into general alignment with said pipe portion.

2. A drier roll having a supporting journal provided with a horizontal passage of restricted diameter, and, in combination therewith, a siphon pipe assembly adapted for entry through said It will be unpassage and for removal therefrom, said assembly comprising a supporting pipe portion extending horizontally through said passage. a pipe extension within the drier roll depending angularly downwardly from the end of said pipe portion, interconnected attachment members on the adiacent ends oi. said pipe portionand said pipe extension, the attachment member on the pipe portion having a concave seat and the attachment member on the pipe extension having a convex seat engageable therewith, said seats normally providing a substantially fluid-tight conmotion and maintained in seating engagement merely by the weight of the extension pipe and its connected attachment member, said attachment members having interengag'ing portions a!- i'ording upward movement of the pipe extension into general alignment with said portion.

3. A siphon pipe assembly adapted for entry through a restricted passage of a drier roll comprising a supporting pipe portion adapted for horizontal positioning, a member mounted on one end of said pipe portion and having a curved seat and a passage communicating with said pipe portion, an annulus mounted on said member, an elbow pivotally connected to said annulus and having a curved seat engageable with the seat on said member to provide a substantially leak-prooi. joint, a pipe extension fixed to said elbow and normally depending from said pipe portion but in communication therewith, the seats of said member and elbow being maintained in seating engagement merely by the weight or the pipe extension and said elbow, said pivotal connection afiording upward movement the pipe extension into general alignment with said pipe.
