Wringers are commonly provided Withrelease mechanisms by which zthe pressure mia-y be instantly released in-case --of accidcnt; 'Ihey are also provided with rareset mechanism by which they may .bequiokly reset. The reset mechanism of thepresent invention is .cperable with the releasesdevice. Features and'details rQf .the -inven-- tion will-appear fromthespecifica'tionsand claims. .A preferred enibodimentef [the inventimiiis v illustrated in the accompanying drawing a-sfol lows:

The [latch :bar has front to back portions i22, .these portions 22 of the arms 48 being, adjacent :to slots 23 in the front to back portions of the walls of the stile. Trip bars :24' extend across the wringer and The'arms at the reset end of the :Wringer are provided with on the line.66 in Fig. 4 showing the trip bar connection therewith.

Fig. '7 a similar view with a different position I of the trip bar. a

I marks a base of a wringer, 2 and 2a stiles extending upwardly from a base, '3 a top bar for the wringer frame. Wringer rolls 4 and 5 are mounted on the frame, the rolls havingshafts 6 and l respectively. The'shaft 6 is journaled in bearings 8 arranged in the stiles and resting on the base. The shaft 1 is journaled in bearings 9 A spring l0 operates on the upper bearings and exerts pressure on the rolls.

The top bar has an interlocking detachable connection il at one end of common construction.

At the opposite end'of the top bar there is a reset lever [2 which 'is hinged on the top bar at I3. The reset lever is of channel form forming an interior pocket. It is connected with the stile through links M, each link being pivotally connected at IS with an ear |5a on the stile and The links and lever form a toggle by which the top car may be pulled down to reset the pressure in awell known manner.

A latch 11 is carried by an arm and engages the rod is and locks the resetting leverin set position. The latch bar is extended by a fork I8 extending both sides of the stile 2 and going through slots I9 in a front to back portion of the wall of the stile. The arms 18 have perforations 20 and pivot pins 2| pass through these perforations and the stile Wall, pivotally mountfiat portion-s; a, the frat portions "being formed by. bending the ends of the arms providing :out-

The arms of the trip barsjarezsprung apart to' permit the insertion of the assembly of the bent ends of the arms into the slots 23 of the wringer. I

A spring lla yieldingly pulls the latch arms upwardly and locates the top surface of these latch arms under the flat portions 25 and holds the flat portions normally in contact with the upper edges of the slots 23, thus yieldingly loeating the trip bar 24.

A cam surface 23 is arranged on the latch plate opposite the catch l1 and this operates on the rod It to force it outwardly and with it the lever l2 when the latch arm is depressed.

In the operation of the device, when the trip bar is moved inwardly or outwardly, one edge or the other of the fiat portion 25a operating as a fulcrum against the upper edge of the slot 23 forces the opposite edge of the portion downwardly and this, operating on a cross portion 22 of. the arms, depresses the latch plate, releases the hook IT, and at the same time, through the cam 28 forces a release movement of the setting lever. Preferably the setting leveris set at approximately neutral so that the friction on the surfaces of the catch l1 and the cam 28in a release movement is very little, and the friction of the rocking parts of the trip lever-is reduced to a minimum so that a very sensitive yet very The tar-ms -opflat portion at an edge operating as a fulcrum and the flat portion at the edge opposite the fulcrum acting on the latch to trip the same.
