RENE BABLON, OF LES LILAS, FRANCE.

CONSTRUCTION OF COCKS.

Application filed February 20, 1913.

To all whom it may concern.

Be it known that I, RENE BABLON, manufacturer, citizen of the French Republic, residing at 14 Rue de Bagnolet, Les Lilas, Department of the Seine, France, have invented certain new and useful Improvements in the Construction of Cocks, of which the following is a specification.

In the known types of cooks, the different members are kept in place by means of screws, nuts, dowels, etc. These securing members are apt to work loose, the result being, at least, a leakage or even the loss of one of the principal members. In certain cases, serious accidents have resulted. Fur thermore the dismounting and assembling of these cocks require a rather long period of time and the use of tools which are not always accessible.

The cock forming the object of the pres ent invention is for the purpose of prevent ing the possibility of the members working loose accidentally and getting lost. Moreover it insures automatic compensation of the play which tends to arise in consequence of the wear of the spigot and the body of the cock, all leakage being thereby prevented. However, the dismounting and assembling of these members can be eliected manually in a very short period of time and without the necessity of using any kind of tool.

The accompanying drawings represent, by way of example, three variants of the device arranged in accordance with the principle of the invention.

Figure 1 is a lateral elevation of a cock. Fig. 2 represents the same cock in longitudinal section. Fig. 3 is a plan. Fig. 4 is a plan view at the moment of dismounting. Fig. 5 shows a vertical section through the axis of the spigot. Fig. 6 is a longitudinal section through a variant of the device. Fig. 7 is a plan of said variant. Fig. 8 represents partly in elevation and partly in section, another variant more particularly in tended to be operated by means of cords or draw-chains. Fig. 9 is a plan of this variant. Fig. 10 is a view of the spigot and body of the cock from below. Fig. 1 gives a view of the cock as a whole, consisting essentially of three members; a body 1, a spigot 2 fitting into said body and a handle 3, of any shape whatsoever, intended to turn the spigot into the opening and closing positions.

The body 1 is provided with a portion 4,

either cast in one piece with or screwed on to it, and exhibiting a circular groove 18 and a corresponding projection 8 interrupted by a gap 91O as shown in Fig. 4:. Two recesses 5 are provided in the upper flange of the groove 18. The spigot is provided with a groove 17 enabling it to be embraced easily by the portion marked 2 in Fig. 1.

The operating handle 3 2) is provided with two lugs 6 of such dimensions that they can enter the recesses 5 and move inside the circular groove 18. This handle is able to fit, without any play, into a slot 16 in the spigot 2, (Fig. This latter is provided with a projecting pin 11 and a passage 1-1 housing a spring 15. The passage 14 is bounded at its upper portion by the slot 16. The aggregate thus constituted operates in the following manner: The spigot 2 provided with the spring 15 being inserted into the body 1 so that the slot 16 faces the recesses 5, (Fig. t) the handle represented by broken lines is inserted in the slot 16. The lugs 6 pass through the recesses 5 and enter the circular groove 18. At this moment, the projecting pin rests on the ridge 8, (Fig. 4) and all that is needed is to turn the handle 3 toward the left in order that, as a result of the movement of the spigot 2 in the same direction, the said pin may drop into the gap intended for its reception. Under the action of the spring 15, the spigot enters the body completely and, henceforward, its movement of rotation will be restricted by the pin making contact against 9 or 10, respectively. The handle will therefore take up the extreme positions marked by full and broken lines in Fig. 3, according as the cock is open or shut, describing the arcs a .7), 0 d. This movement however will never bring the lugs 6 oppo site the recesses 5. On the other hand, the spring 15 by bearing against the handle 3, keeps the spigot 2 embedded in the body 1 and the pin in its gap. It is therefore im possible for the aggregate to become dismounted spontaneously and, in proportion as the spigot gets worn into the body, the play is automatically corrected by the action of the spring 15. Finally, this spring being situated internally and thus protected from all shook does not get out of order. To take the cock to pieces all that is needed is to draw the spigot out of the body in order to disengage the pin from its gap, then turn the handle 3 so as to bring it opposite the recesses 5, whereupon the handle and spigot can be drawn out with ease. Owing to its direction, the movement for drawing out the spigot cannot be performed except with the definite intention of taking the cock to pieces.

Figs. 6 and 7 represent a constructional variant of the cock just described. It is easy to see, from an examination of Fig. 6, that this variant is constituted by the same members as the previous cock with the sole difference that the groove 18 is arranged internally instead of on the outside. The recesses 5 are consequently arranged on the inside of the upper flange of the groove 18 and the lugs 6 of the handle point toward the outside instead of toward the inside. This variant has been drawn as a cock with a body that is open underneath, an arrangement enabling the spigot to be pushed up from below when taking the cock to pieces, and

I since the groove 17 is no longer needed, the

length of the spigot can be reduced.

Figs. 8, 9 and '10 show another variant based, in all cases, on the same principle. The spigot of the cock is formed of a truncoconical core 2 provided in its upper part with a projecting ridge 19 in which are arranged two gaps 2021, 2223 in diametrically opposite positions, while in its lower part it is provided with two diametrically opposite sectional ridges 24: and 25 each of which occupies one fourth of the circumference (Fig. 10)." When the spigot is in position in the body of the cock, its movements are limited by a projecting pin 11 carried by the body and against which abut theends of the sectional ribs 2 1 or 25. The handle consists of a cylindrical metal rod 26 the ends of which are of smaller diameter than the central portion 27. The upper part of the body is I pierced by two diametrically opposite grooves, one of which is visible at 28 in Fig. v8. The widthof these grooves is equal to the diameter of the ends 26 of the handle rod. At one of their diametrically opposite ends, each of them exhibits a circular enlargement 29 the diameter of which corresponds to that of the central enlarged portion 27 of the handle rod. A spring 7 15 is housed in a cavity bored along the axis of the spigot.

This cock is assembled in the following manner: The spigot is inserted into the body so that the gaps 20-21 and 2223 are respectively opposite the enlarged orifices 29. The pin 11 then bears on one of the sectional ribs 24: or 25, the spring is placed in its housing and the rod 26, 27 is inserted in one of the orifices 29, passed into the gaps 2021 and 22 23 and finally pushed through the orifice 29 diametrically opposite to that through which it was inserted. During the opera-1 tion, care has been taken to lower the spring 15 so that once the rod is in position it is underneath said rod and bears against same (Fig. 8.) If then the spigot be turned by pin 11 ceases to bear on one of the sectional ribs 24 or 25 and the spigot takes up its place inside the body under the action of the spring 15. From this moment, it is evident that the cock can no longer be dismounted unintentionally, the movement of the spigot being restricted to 90 by the pin 11 and the projections 124. and 25 which are disposed in such a manner that the rod 26 can no longer come opposite the orifices 29 when it is moved. The rod 26 is therefore held in place owing to the fact that its enlarged portion 27 cannot pass through the grooves 28. To take the cock to pieces all that is needed is to press against the bottom of the spigot to cause it to rise andrelease the pin 11,, the rod 26 being then turned to bring it opposite the orifices 29, and drawn out. 7

The cocks described above present the following advantages: The maximum safety in use, owing to the elimination of any parts apt to cause leakage; immediate dismounti-ng without the aid .of a tool, thus facilitating the rapid greasing and cleaning; automatic compensation of wear. on the spigot similar members employedin the. same way,

without departing from the principle of the invention.

-What I claim is:

A cock comprising in conbination a body portion formed with a circular groove, with the upper flange thereof presenting two diametrically opposite notches, and an upper arcular ridge; a slotted spigot located in said body portion and carrying a pin primarily engaging said ridge; a handle adapted to seat in the slot in said spigot and formed with lugs adapted to pass through said slots prior to'their engagement with said circular groove; and a spring located between said spigot and said handle and adapted upon a partial rotation of said handle and spigot to force the spigot into a position in which said pin is located between the ends of said arcular ridge.

In testimony whereof I aflix'my signatur in presence of two witnesses.
