The arm BW' is provided with a projection B1 remote lrom its pivoted extremity and adapted to engage the arm B ot' the lever during the closing operation ot the cap and adapted to be engaged by the arm B7 of the lever when the latter is in the locking posi tion. the projections B1" the extremities of the spring are connected with the partli o'l the device, as shown in Figs. 2 and 3 ol the drawf ings.

Assuming that the device is open, as shown in Figs?) of the drawings, il,t it is desired to close the same the cap B" is thrown over, so that the packing B covers the top of the tube, and as the cap is thrown into place the part B strikes the part B and partly raises the arm B of the lever, which is then thrown over toward the right. whereby its arm B7 is made to engage the part Bl, which is bool;- shaped. The movement ot the lcver-arn'i lll is continued until the arm B7 passes what may be termed the dead-center position, whereby the tendency oi the lever is to hold the cap in place. Now il it is desired to open the cap it is only necessary to lift the arm BS, when the spring B will open the cap, as heretofore explained. As the lever B is thrown to the locking position its projections l'l" travel in the slots lli: trom one extremity ot said slots to the other in a manner that will be readily understood. rlhe hook-shaped extremity l'l ol. the arm Bw acts as a stop to prevent the movement ot the lever-arm B7. The projections l then travel forwardly or toward the right, referring to Fig. 2, until they reach the forward extremities ol the slots B3. The arm lll has then been thrown past the dead-center position, as heretofore explained.

Having thus described my invention, what Yl claim is- 1. In a valve-cap, the combination ot a body part adapted to be connected with a hollow valve-stein, a spring-actuated cap pivotally connected with the body part and having a tendency to assume the open position, and a locking-lever niounted on the body part and adapted when thrown to the locking position to hold the cap in the closed position, the body part having a curved slot, and the lever having a lateral projection engaging said slot and adapted to travel therein tor the purpose set liorth.

2. ln a device of the class (ileseribed, the comliination o't' a slotted body part adapted to be connected with a tubular valve-stem, aeap pivotally connected with the body ot' the device, a spring having a tendency to hold the cap in the open position, a lever havinga lateral projection ,intermediate its extremities. said projection engaging the slot ol the body part and traveling therein Ytor the purpose set l'orth.

3. ln a device oi the class described, the

Alter ceiling the spring Bm around combination with a tubular valve-stem, of a body part connected therewith, the body part having slotted ears, a cap connected with the body part, a locking-lever located between the ears of the body part and having' projections intermediate its extremities engaging' the slots ot' the said ears.

4. The combination with a tubular stem, of

a body part adapted to be secured to thestem and slotted, a cap pivotally connected with the body part opposite the slotted portion, a lever mounted on the body part and having a projection intermediate its extremities engaging the slot otl the body part, said lever being adapted to hold the cap in the closed position, the lever and the cap moving in opposite directions during their opening action.

The combination with a device to be closed, ot a part connected with the open extremity thereof, acap pivotally connected with the. said part and adapted to close the opening in the device, and a locking-lever mounted on the said part on the vopposite side of the device trom the connection of the cap, the said part being slotted and the lever having a lateral projection to engage the slot, the lockinglever bei ng ad apted to hold the cap in the closed position.

6. The combination with a device to be closed, ot a body part connected with the device, a cap pivotally mounted on the body part adjacent the device and having a hook remote from its pivoted portion, a lever having projections intermediate its extremities, said projections engaging' slots formed in the body part, the said lever being' provid ed with a locking-arm adapted to engage the book of the cap whereby the latter is locked in the closed position when the manipulating-arm ot' the lever is thrown to the position above the cap, the projections of the lever traveling in the slots of the body part Yfor the purpose set forth.

7. In a device of the class described, the combination with a device to be closed, of a plate threaded thereon, a nut forming an adjustableI stop t'or the plate, the latter having o1)positely-located ears, a cap pivoted to the ears on one side of the plate and having' a hook-slniped part opposite the pivot, the other ears being slotted, a triplearmed lever having lateral projections engaging the slots ot' the said ears, two arms ot' the lever being located on opposite sides ot' the projections and occupying` positions approximately in alinement with each other, while the other arm occupies a position at right angles or approximately at right angles to the alined arms, the parts beingl connected and arranged to coact, substantially as described.

ln testimony whereoiu I afiix my signature in presence of two witnesses.
