DOOR.
Application filed July 6,
To all whom it may concern:
Be it known that I, DANIEL B. BANKS, a citizen of the United States, and a resident of Baltimore city, in the State of Maryland, have invented a certain new and useful Improved Door, of which the following is a specification.
My invention relates to an improved door, lid, cover, detachable head, or other closing member, hereinafter referred to as a door, for boilers, tanks or other containers.
It has for its object the construction of a door which may be quickly closed and sealed and as quickly opened with a minimum expenditure of energy.
It has for its further object the construction of a sliding door which may be secured against the action of both positive and negative pressures, that is, pressures above and below atmospheric pressure, without the use of bolts or similar fasteners.
It has for its further object the construction of a sliding door which may be sealed against either positive or negative pressure, or against a variable pressure changing in one operation from positive to negative.
And it has for its further object the construction of a sliding door which may be sealed as above by the use of a movable gasket controlled in its movement at a single point from which single point pressure may be applied as a practically uniformly distributed load to the entire circumference of said gasket.
\Vith the foregoing and other 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.
To more fully understand my invention 1 will refer to the accompanying drawings, in which:
Figure 1 is an end view of the door and the container, the door being in the removed or open position; Fig. 2 is a transverse hori- Specification of Letters Patent.
Patented June 21, 1921.
1917. Serial No. 178,996.
zontal section of the same; Fig. 3 is a section through the door, cylinder, and interior gland, showing the door in closed position and the gland in the advanced position, Fig. 1 is a plan of the gland in position within the head, showing the system of levers and distributing girder arms, the head being in section.
Similar numerals refer to similar parts throughout the several views.
1 is the shell of the container, 2 is the receiving edge of the container having a projecting lug 3 on one portion thereof, and on the other portion a projecting rim 4. 5 is the outer member of the door carrying on the advancing portion thereof a projecting rim 6 and on the following portion thereof posterior-l projecting lugs 7, this outer member of the door being bolted to the central member of the door 8. 9 is the interior annular gland, the advancing portion of which 10 engages a projecting shoulder 11 on the receiving edge 2 of the container. 12 is a flexible gasket or other packing carried by the gland 9. 13 is an exterior wheel actuating a screw 1-l which is connected through a stuffing box 15 with a series of levers 16, pivoted at the points 17 to the interior of the head 5. 18 are cross arms connected with th levers 16 by slotted posts 19 and attached to distributing arms 20 which are,again attached through distributing arms 21 to gland 9. 22 is a carriage supporting the door, which is guided by a bar 23 directing a guiding shoulder 2a. The carriage 22 is mounted on wheeled truck 25 and travels upon a track 26. 27 is a screw and wheel mounted upon a swivel joint at 28, so that it may eni new locked in position against a movement in the direction of the axis of the cylinder by the pro ecting lugs and rlm on the contalner and door respectively, and is locked against movement in a transverse direction by the advancing gland. The seal being secured by direct in chanical application of pressure to the gland through the rotation of the wheel 13 is independent of the internal pressure, and therefore is a complete seal against both positive and negative pressures or against a pressure changing from positive to negative during the course of a single operation.
If it now be desired to open the door the wheel 13 is revolved in the opposite direction, and the gland 9 withdrawn by the force applied through the levers 16, the cross girder arms 18 and the distributing arms 20 and 21 until the gland 9 is clear of the plane face of the container member l. The door is then withdrawn by the removal of the car 22, screw 27 being used if necessary to start the car in motion. Thetrapezoidal chan1- ber containing the gasket 12 secures the withdrawal of the gasket or other packing with the gland 9.
Having thus described my process what I claim and desire to secure by Letters Patent is:
