JOHN C. GLENN, 0F ERIE, PENSYIJVANIA.
DEWATERING MECHANISM FOR PAPER-MACHIN E DRUMS.
Application filed January 5, 1920. Serial No.
To all whom it may concern c it known that I, JoHN C. GLENN, a citizen of the United States, residing at Erie, in the county of Erie and State of ennsylvania, have invented certain new and useful Improvements in Dewatering echanism for Paper-Machine Drums; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.
y invention relates to paper making machines and the object thereof is to provide means and mechanism whereby the water of condensation can be ejected from the drier drums of paper machines without undue loss of steam.
The features of my invention are hereinafter fully set forth and pointed out and are illustrated in the accompanyingdrawings in which:
' Figure 1, is a side view partially in section, of a drier drum with my improved mechanism thereon.
ig. 2, is an end view thereof with one of the journals of said drum in vertical section on the line 2-2 in Fig.1.
Fig. 3, is a longitudinal vertical section of a drum journal with my improved mechanism thereon.
ig. 4, is a transverse section on the line In these drawings A indicates a drier drum of ordinary construction, being rovided with supporting journals A, A; the heads A of the drum being provided with cylindrical shoulders A in the usual manner. A indicates the usual through into the drum A. I
In carrying out my invention I drill 1ongitudinal ducts B into one of the journals A, which terminate at the periphery of the cylindrical shoulder A on opposite sides of the journal A, and within the drum A I place buckets C C at opposite sides of said drum, which buckets are connected by means of tubes D D with the ducts B B in the journal A.
Secured on the end of the journal A by means of bolts 6, is a cap E which is pro- Specification of Letters Patent.
, which K, and the Patented Apr. 12, 1921.
vided with holes B, which coincide with the ducts B and with a screw threaded central opening E in which is secured a pipe F which is concentric with the opening A 1n the journal A and extends forwardly into the drum A, as shown in Figs. 1 and 3.
Secured to the cap E by means of an internally screw threaded collar E thereon, is a stem G of a ball and socket jointpart G of the ball thereof being on said stem, and th ball beingrotatable upon the journal G of said stem for the purpose hereinafter set forth. The stem G and journal G are p opening with the outer end of the tube F. The stem G is also provided with ducts g g which communicate with the ducts B B in the journal A and cap E,- and the portion of the ball H is provided with a segmental slot H (see Fig. 4) which communicates with one of the ducts g in the stem G. 7
Upon the ball portion H I place a hous ing J which is provided with a duct J communicates with the central openlng G in the stem Gy and with a duct J which communicates with the segmental slot H in the ball portion H.
The housing J being secured in place by means of the housing member K which fits over part vof the ball portion H and the ball portion G, and is connected with the housing portion J by means of bolts K which are screwed into openings in the flange J 3 in the housing J and pass through openings in the flange on the housing member K, and are provided with springs K by means of which the housing member housing member J are drawn toward each other so as to tightly compress the ball G and H between them.
The ball member H is provided with a hand lever L by means of which the ball member H can be oscillated as desired upon the journal Gr of the stem Gr for the purpose hereinafter set forth. I
In operation the drier drums of a paper making machine are rotated in the direction of the arrow in Fig. 2, and steam is introduced thereinto through the duct J in the ousing J, and thence through the duct G and tube F into the drum, and as the drum rotates the ducts g g in the stem G successively coincide with the segmental slot H in the ball member H, which communicates h coincides e remaining portion H of said the drum changes tion with'the exhaust duct J 2 in the housing J,
and during the period of such coincidence steam or water of condensation can flow outwardly through the duct B in the jour nal A, and the duct 9 in the stem G which coincides with the segmental duct H and the duct J v In Fig. 2 by means of broken lines I show the substantial position of the body of water within the .drum during the rotation of the drum, and it is well knownthat the position of this body of water within according to the speed drum-2i. e. as the speed higher up Within the of rotation of the increases the water is drum than when the in order not to waste steam when the bucket C is not in the water the ball portion H acts as a valve to prevent the escape of steam from one of the ducts g while its connected bucket C is not in the water; and as the body of water M within the drum changes its osition, it is necessary that the timing of t c coincidence of the duct 9 with the segmental slot H, or with the exhaust duct J 2 should be advanced or re tarded and for this purpose I have provided the ballportion' H and made it rotatable with relation to the ball portion G so that as the drier drum is caused to rotate at the greater speed, the ball portion H having the segmental slot H therein, is manually rotated to substantially the same radial ied by thebody of water uct lg will coincide with the substantially the same instant the buckets C within the drum A enters the body of water M therein, and the slot H should be of such width that the duct y will cease to' coincide with the slot H at substantially the same instant thatv the bucket passes out of the body of water M- so that there will be substantially no escape of steam or exhaust out of the duct J 2 when so that the slot H at that one of the bucket C is not in the position within the drum A where water will accumulate.
N indicates a pin or bolt adapted to pass.
through the openings N in the flanges J 8 and and through an opening in the handle I to maintain the ballportion .H in the desired stationary position, while the stem G continues to rotate in unison with the journal words, the bolt N maintains the ball por- H in the desired adjustable osition with relation to the housin J, w ile the stem G and ball portion "continue to rotate. 7
It is apparent therefore, that by means of my improved mechanism the exhaust ducts from the interior of the drier drum will only be open to the atmosphere'when the buckets C within the drum are at such a position that the water will be forced outby Letters speed is slow; hence,
