Title: Combination stop-cock for preventing unauthorised access to liquid or gas supplies
IPC: F16K35/08
Filed: 1932-09-26
Abstract: 393,151. Combination-lock stop-cocks. HEIMEIER, T., 15, Erwitterstrasse, Lippstadt, Westphalia, Germany. Sept. 26, 1932, No. 26682. [Class 135.] A combination stop cock for preventing unauthorized access to liquid (petrol) or gas supplies comprises two (or more) concentrically nested rotary cocks 5, 6 having their through passages out of register until aligned by a common rotary cap 9 operable in opposite directions in succession. To open the cock the cap 9 is first rotated idly until an internal projection 11 strikes a projection 12 of the inner cock 6 which is thereby turned and with it the outer cock sleeve 5, by reason of a spring-pressed driving-pin 16 engaging the end of a tapered groove 15 in the outer sleeve ; this turning action continues until the passage parts 51, 5<11> are in register with the casing parts 4, 4<1>. This first position is indicated by a pointer 17 on dial markings at 18. During this preliminary movement the teeth of a ring 13 on the outer sleeve slip past a pawl 14. The cap 9 is now rotated idly in the opposite direction until the projection 11 strikes the projection 12 of the inner cock 6 on the reverse side, whereupon the inner cock is rotated until its passage 61 is in register with the alreadyaligned passages 4, 41, 5, and 51 in which position the fluid flow is obtained. This second position is also known by means of the pointer 17 and prearranged markings on the dial 18. During the second part of the opening movement the pin 16 slips freely out of the tapered slot 15, whilst the pawl 14 engaging the teeth of the ring 13 prevents the backward movement of the outer sleeve 5 from its pre-set position. Additional dummy rings with numbers or other markings may be mounted on the cap 9 serving merely to mislead further any unauthorized persons.

The plate 1 fixed to the door frame has two projections 2, 6 forming a pathway with divergent sides 3, 7, the wider ends of which have notches 5, 8. It also has a projection on the same side as the projections 2, 6, and an arm 11 on the other side carrying a pivoted catch 9 with a finger-piece 10<1>. The plate 12 secured on the edge of the door has a projection 20 with feathers 20' adapted to engage the notches 5, 8 when the door is closed, and a roller 19 which enters the narrow part of the pathway between the projection 2, 6 on the plate 1 to form a guide. Pivoted on the plate 12 at 14 is a catch 13 having a handle 15 integral with it and a handle 21 pivoted to it and guided by the engagement of the pivot pin 24 in a slot in the plate. When the door is closed, the teeth at the lower part of the catch 13 ride up the incline 4 on the part 2 of the plate 1 and drop into engagement with the teeth on the part 2. In the first position of engagement the extension 16 of the catch 13 covers the slot 12<1> in the plate 12, and operation of either handle is sufficient to disengage the teeth to open the door. If the door is pushed completely home, however, the teeth interengage in the manner shown in Fig. 6, and the extension 16 is clear of the slot 12<1>. In this position, the catch 12 can be swung over to engage the slot 12', being retained there by a spring-pressed ball 17 in the end of the extension 16. The catch 10 must now be removed before the handles can be operated to release the door. The projection 9 forms a stop to limit the movement of the catch 13.
