PATENT ALBERT HANSEN, OF COPENHAGEN, DENMARK.

SPECIFICATION forming part of Letters Patent No. 666,383, dated January 22, 1901. Application filed July 13,1900, Serial'No. 28,471. (No model.)

T0 [6 whom it may concern.-

Beit known that I, ALBERT HANSEN, manufacturer, residing at Store Torvegade 24:, Copenhagen, in the Kingdom of Denmark, have invented certain new and useful Improvements in or Relating to Self-Olosing Cocks for Water or other Fluids, (for which I applied for patents in Denmark on the 28th of March, 1900, No. 3&9, and in Germany on the 27th of May, 1900,) of which the following is a specification.

The invention relates to a self-closing cock for water and other fluids characterized by the feature of the outlet-spout or outlet-pipe of the valve arranged in or upon the cockcasing or valve-casing and mounted movably along the same, to which it is kept by a loose handle, which can be turned around the cockcasing and which when it is operated moves the outlet-spout of the cock-casing so that the cock is opened and again is closed when the handle is released, as a spring in the cock then will bring the parts back to their initial state.

The invention is illustrated in the annexed drawings, in which- Figure 1 represents a side view of the cock. Fig. 2 shows a vertical longitudinal section through the cock, and Fig. 3 shows the handle seen from above.

The cook or the valve consists of a cock or valve casing a, perforated longitudinally, which is affixed to the ailluX-pipe b and on the lower end of which the outlet spout or pipe is screwed.

In the cock or valve casing a, is situated a valve-rod d, surmounted with a valve f, which has a packing, and which valve normally is pressed down against the upper end of the cock-casing and shuts up the supply. This is effected through a spiral spring c situated inside the cock-casing and around the valverod and the upper part of which is pressed down against the breast of the cock-casing, while the lower end is pressed down against a perforated steering-piece h. The upper end of the valve-rod bears also a steering-piece 2', furnished with passages for the fluid. The

steering-piece is placed against a disk 7.0, situated in a seat of the outlet-pipe c, furnished with passages for the Water.

On the outside the cook or valve casing is furnished with a circular groove or flange Z, while the outlet-pipe in the upper end has a ring-shaped flange m. These two flanges are grasped by the claw-formed end of the loose handle a, the end of which consists of an upper and two lower claws 0 p p, respectively, the upper claw o of which grasps in the groove or flange Z, while the two lower claws p take against the down side of the flange m. When the handlenis pressed down, the outlet-pipe 0 will be brought upward, and the disk It will press upward the steering-piece h and then also the valve-rod and the valve, and thus the cock is opened. As soon as the valve is free the spring will bring back into the initial position all the pieces and shut the cock.

For preventing the exit of the fluid by a higher pressure between the cock-casing and the outlet-pipe c a packing r can be placed on the lower end of the flange Z, and on the upper end of the flange m may be arranged a triangular profiled rim 3, which when the outlet-pipe is pressed upward is forced into the packing-ring and closely shuts the opening between the two flanges. ment of packing is not shown in Fig. 1.

The handle 11 may, as will be seen, be turned around the cock, so that it may be turned out to the side, in which position it is most convenient to handle it.

I claim- A self-closing cock for water and other fluids, characterized by an outlet-pipe, arranged in or upon the valve-casin g and situated movably on the same, which pipe is kept on its place and may be moved along the cook or valve casing by a turnable handle, placed loosely around the cook, the claw-formed end of which handle grips into the flange or the projection of the casing and of the outletpipe, and which pipe, when it by the handle is moved upward, operates the valve, arranged in the casing, whereby the cock is opened by depressing the handle and when the handle is released is closed by the action of the valve-spring.

In witness whereof I have hereunto set my hand in presence of two witnesses. I

ALBERT HANSEN.
