FRIEDRICH HOHL in CANNSTATT. Pipe coupling.

Patented in the German Empire on March 10, 1895.

The pipe coupling forming the subject of the invention is shown in the drawing, namely shows:

Fig. Ι the assembled coupling on average,

Fig. 2 is a side view,

Fig. 3 shows the clutch in the released state and

4 shows the top view of the tensioning disk (h ^{1 and} h u).

The pipe coupling consists of two symmetrically manufactured pipe end parts, each from a sealing socket ff ¹ respectively. f ^'11 J with a shoulder behind which the pressure washers (I and II) are positioned. On the thrust washers there are two pegs with keyways (a ¹ b ^l and a ¹¹ b ^u ) and two holes in each of them (c ¹ d ^{1 and} c ¹¹ d ¹¹ ). The tension disks (h ^{1 and} h ¹¹ ), which are provided with wedge surfaces (k ¹ and k ¹¹ ) and a slot for a stop pin, lie on the pressure disks; the adjusting screws (i ^{1 and} i ¹¹ ) are also attached to the same.

The tensioning disk (h ^{1 and} h ¹¹ ) can be rotated to a limited extent on the pressure disk (I and II) by means of a stop pin; but both together can be rotated on the sealing socket (f ¹ or f ⁿ ) and remain in the position given to them by the pressure of the spring (I ^{1 and} I ¹¹ J against the attachment of the sealing socket.

If now the grooved pins of the thrust washer I are inserted into the holes in the thrust washer II introduced, so step simultaneously the grooved pin of the thrust washer II in the holes of the Thrust washer I, and the tensioning washer can then depending on the opposite side with the wedge surfaces engaged in the grooves of the tenons and with the adjusting screw on the toothed edge of the thrust washer (I and II) can be determined as desired.

The sealing stubs can be made of cast steel, phosphor bronze or other suitable Metal, the seal but also by means of inserts on the sealing surface of otherwise suitable Material to be made.

To use the coupling, it is sufficient if only one locking by means of a clamping washer and adjusting screw is effected; the second can be left in reserve.

Claims (1)

Patent Claims: (BEZW f ¹ f. ^U) of two symmetrical parts existing pipe coupling, characterized in, that on the sealing surfaces supporting studs per one (BEZW a ¹ b. ¹ α ¹¹ b ¹¹⁾ with two pins and two holes (c ¹ d ^l or c ¹¹ d ¹¹ ) provided disc (I or II) is rotatably arranged in such a way that when coupling together the pins of one disc pass through the holes of the other and the end The coupling is effected by a second disc (h ¹ or h ¹¹ ) which can be rotated to a limited extent on the first by a stop pin, in that its wedge surfaces (k ^{1 and} k ¹¹ ) slide into the lateral keyways of the pegs as soon as the disc (h ^{1 and} h ¹¹ ) against the disc (I and II) by a screw ft ^{1 and} / or. i ⁿ j is twisted.
An embodiment of the under ι. marked coupling, in which the rotatable disks are under the pressure of a spring (I ¹ or I ¹¹ J , 'so that they remain in the position given to them. For this purpose ι sheet of drawings.
