Application filed February 5,1927, Serial No. 166,033, and in Great Britain hiovember 11; 1925.

This invention relates to improvements in taps for fluids, more particularly designed for use with oil' drums and barrels, of the kind comprising twotelescopingtubular members, which are formed with slotsyor apertures soarranged that when the members are collapsed the tap is closed and in an extended position of the said members the slots or apertures provide a free passage for a the flow oi the fluid from the container.

According to my invention in a tap of the described type'l so construct the said members that when they are extended andrelatively rotated the slots or apertures therein provide a tree passage for the flow of. the fluid from the. container.

In a suitable arrangement embodying the invention the tap comprises two telescoping tubular members the inner ofwhich is closed at the ends and provided with a slot or aper- I ture near each end and the other or outer member provided near the front end with a similar slot or aperture-with which the rear slotinthe inner member is designed, to register when vthe said member is extended and partially rotated by a. projecting knob or enlar ement at its outer end. Means, such as a ongitudinal slot inthe outer member with which .enga es a pin in. the inner member, are provide for preventing the inner member "from being rotated until it is fully extended, and also for the retention of the tap in the fully open position, such latter means consisting, for exam le, of a niche or right-angled extension 0" the front end of the longitudinal slot into which the store said pin its and is moved to bring the aper-' tures into coincidence. The rear end of the longitudinal slot may be formedwith a rearwardly inclined extension so that in the,

' closed position the inner tubular membercan be rotated to make a fluid-tight joint between the knob on its outer end and the front end of the outer member, in the known manner. I

The operating knob on, the inner telescoping member may, however, be dispensed with and a key employed instead and for this purpose the closure at the front end of the said member is formed hollow to receive the bit of the key with a key hole in the front wall so that the bit when inserted can be turned to engage between the said wall and the rear wallcand efl'ect the longitudinal movement of the member, the bit making contact with a stop in either direction of to tation to effect the required rotation of the said member.

To enable the invention to be fully understood I will describe it by reference to the accompanying drawing, in which:

with a suitable paclring ring It, and is shown as being of polygonal form in order that the" outer member I) can be screwed by a spannerinto the necessary opening in the container vessel A, which is indicated by dot and dash lines in Figures- 1, and 7 the said member and opening being formed with correspond ing screw-threads for this purpose, as in dicated,

The tap is operated. as follows p In the normal, or closed position, the two tubes 0: and Z) are collapsed to the position shown in Figures 1, 3 and 5 and the'knob a, on the outer endof the inner member a, is all that projects beyond the wall of the container A, If it be desired to withdraw the fluid from. the container A. the inner member a is twisted anti-clockwise by the knobs and then pulled outwards as far as possible to the position indicated in Figure 6. It is then turned through an angle of 180 to bring the apertures e and g in the inner and outer members, respectively, mto

register, as indicated in Figures 7 and 8,

thus providing a'free passage through the sald inner member a for the fluid which issues through the aperture f in the front end of said inner member.

, Figures 9 to 13 show the arrangement where the knob is dispensed with and the inner memberc constructed. so as to require lieyforits manipulation In this arrangement the closure (1 is made hollow to form the space or chamber 71 to receive the bit moot the key, Figures l2and 13, which inserted through the lrey hole at in the front wall 0 of the chamber 5 and turned to fit between. the said wall and the rear wall This engagementof the key-bit between the two'walls 0 and p enables the longitudinal movement of the inner me1nber'a to be eil'ected by the key, q, q are the stops within the chamber Z with both of which the key-bit m is turned into contact in either direction to rotate the member e .so as either to engagethe pin i with the slot extension j or the slot extension '1 Although the invention is described more particularly for use withoil drums or barrels, it is to be understood that it is also applicable" to any type of container for liquids and to terminal taps on pipes for Water and other fluids, especially where economy of space is an object,
