6. A lock having a ixed member provided with a seal-seat extension, and a movable member pivotally mounted upon the iixed member and having a cavity forming a main seal-seat adapted to register with said sealseat extension when the movable member is in its normal position, the main seal-seat being accessible at the end opposite to said sealseat extension for the introduction of a seal, and having an interior guard-shoulder extending across the inlet-opening to prevent the movement of the seal in a reverse direction through the inlet-opening, substantially as specified. g

7. A lock having a fixed member provided with a shoulder-cord to form a seal-seat extension, and a movable member having a cavity open at one end for closure by said shoulder of the ixed member when the movable member is in its normal position, and also having an opposite opening for the introduction of a seal, and a guard-shoulder in the cavity of the movable member to cover said in let-opening, said movable member arranged to be shifted in a path across the plane of the alined seal-seats of the tWo members, substantially as specied.

8. A lock having a fixed member provided with a shoulder Which is cored to form a sealseat extension, and a movable member pivotally mounted upon lthe ixed member and provided with a cavity open at one end for closure by said shoulder of the fixed member, and having at the opposite end an inlet-opening, of less depth than the cavity and located contiguous to one Wall thereof, and a guardshoulder located Within the cavity and projecting from said wall contiguous to which the inlet-opening is formed to cover the inletopening, substantially as specified.

9. A lock having a fixed member provided with a shoulder cored to form a seal-seat extension, and a movable member pivotally mounted upon the iixed member and provided with a cavity open at one end to register with said seal-seat extension, the cavity being of greater width than the seal-seat extension and being provided at the opposite end from said shoulder of the fixed member with an inletslit and a contiguous guard-shoulder, in combination with a seal adapted to be introduced through said inlet-slit, and having a tongue or shank adapted to extend through said sealseat extension, and a head of greater Width than the tongue or shank to occupy the cavity of the movable member, substantially as speciiied.

l0. A lock having a fixed member provided with a shoulder cored to form a seal-seat extension, and a movable member provided with a cavity forming a main seal-seat adapted to be closed at one end by the shoulder of the fixed member when the movable member is in its normal position, said main seal-seat being provided at the opposite end with an inletslit and a contiguous guard-shoulder,and having its Wall-opposite to said guard-shoulder inclined inwardly and provided With a channel to register with the seal-seat extension, substantially as specified.

l1. A lock having a fixed member provided with a shoulder cored to form a seal-seat ex-I tension, and a movable member pivotally mounted upon the fixed member and provided with a cavity forming a main seal-seat of greater Width than the seallseat extension, said cavity being open at one end for closure by the shoulder of the fixed member when the movablemember is in its normal position, and being provided at the opposite end with an inlet-slit and a contiguous guard-shoulder, and being also provided in the Wall opposite to said guard-shoulder with a channel registering With the seal-seat extension, in combination with a seal adapted to be introduced through said inlet-slit and having a tongue or shank adapted to be guided by said channel into engagement with the seal-seat extension, and also having a head of greater width than the tongue or shank to occupy the main sealseat, substantially as specified.

12. A lock having a Iixed memberprovided With a shoulder cored to form a seal-seat extension disposed longitudinally of the member, and a movable member pivotally mounted upon the lixed member and provided with a longitudinal cavity forming a main sealseat for registration with said seal-seat extension, and open at the end remote from the pivot for closure by said shoulder of the fixed member, said cavity being provided in one wall With a channel of reduced width registering with the seal-seat extension, and heing reduced in depth as it recedes therefrom, and said cavity being provided at itsextremity contiguous to the pivotal point of the movable member with an inlet-slit, equal in width with the cavity and arranged contiguous to the Wall opposite to that in which said channel is formed, and being, furthermore, provided With an undercut guard-shoulder projecting towardthe Wall in which the channel is formed, in combination with aseal having a reduced tongue or shank adapted to lie in said channel and engage the seal-seat extension, and also provided with a head adapted to occupy the main seal-seat and lie under said guard-shoulder to prevent removal of the seal through said inlet-slit, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
