Title: Float-actuated valve-releasing mechanism
IPC: D06F39/08
Filed: 1937-11-04
Abstract: 505,255. Fluid-actuated valve-closing mechanism. JEPSON, W. Nov. 4, 1937, No. 30209. [Class 135] Apparatus for controlling the level of liquid in a process vessel, e.g. a laundry tub, which requires to be filled to successive different levels, with or without being emptied between twc consecutive changes of level, comprises a float 2 which is located within a chamber 1, disposed in or in communication with the process vessel, and is associated with means foi effecting closure of the manually - opened inlet valve of the process vessel when the liquid in the latter has reached the desired level. The said means comprises a rod 3, secured to the float 2 and provided with axially-adjustable fingers 22, 22<1>, 22<11> which are spaced along the rod in accordance with the required levels of liquid and are also equi-angularly spaced therearound, and two discs 9, 10 rotatable between pillars 8 carried by a cover plate 5 pivotally mounted at 7 on the chamber 1, the plate 5 being provided with a closing rod 19 for the inlet valve of the process vessel. The disc 10 is provided with a central aperture 5<1>, having a projection 21, and equi-angularly spaced pins 20, and the disc 9 with a cable 15, for connection to the valve, and a spring-pressed pawl 11 for engagement with said pins 20. In operation, opening of the valve actuates the cable 15 to effect part rotation of the disc 9, causing the pawl 11 to engage a pin 20 and rotate the disc 10 until the projection 21 is aligned with the uppermost finger 22 on the rod 3. Liquid will then flow into the process vessel, and the float will rise, until the said projection and finger engage, when the cover 5 is lifted, causing the rod 19 to close the valve and permit the release and return of the disc 9, return of the disc 10, however, being prevented by .a second spring-controlled pawl 12 on the disc 9. A second opening of the valve will cause the pawl 11 to engage the next pin 20 and rotate the disc 10 until the projection 5<1> is aligned with the second finger 22<1> on the rod 3, when liquid will again be admitted to the process vessel until it reaches a height corresponding to said finger and the cover 5 is.lifted to effect closure of the valve. This operation is continued until the process is completed.

[Class 53] A dry cell dolly is provided with a wrapping held in place by a thread which is wound simultaneously with the wrapping as shown in Fig. 9, the thread being finally wound round the wrapped dolly as shown in Fig. 14 and secured to the projecting electrode 8<1> by adhesive. Fig. 1 shows a machine for carrying out the above operations in which unwrapped dollies 8 are supported on rollers 7 carried by the links of a conveyer 5. The side chains of the conveyer are sufficiently wide apart to accommodate two dollies placed end to end between them as shown in Fig.. 4, all the devices for applying adhesive and wrapping and tying the dollies being duplicated. Two pieces of wrapping material 42 are first placed on a pair of rollers 7 and a dolly placed on each piece of material. The conveyer then moves the dollies to the position A where means are provided for applying a drop of adhesive to the projecting ends of the electrodes. These means are shown in Figs. 7 and 6 and comprise a lever arrangement 10 which dips a stick 12 in a trough 14 containing adhesive as shown in Fig. 7, and then applies the end of the stick to the end of the electrode as shown in Fig. 6. A pin 16 limits the extent to which the stick is dipped in the adhesive and also steadies the dollies while the adhesive is being applied. The wrapping and tying are carried out in the position B where a roller 17 rotates the dollies beneath it to effect the wrapping. A member 20 pivoted at 18 brings one end of the wrapping material and the binding thread into engagement with the dolly, the thread being fed from a coil 46 through a nozzle 21 which is slidable longitudinally in a holder 21a fixed on a rod 28. As shown in Fig. 8, the rod 28 is reciprocated along the length of the dolly by a lever and cam arrangement 30 so that the thread is wound along the dolly. The arrangement for the second dolly is operated through toothed segments 32. The nozzle 21 is at intervals pushed through the holder 21a and retracted by levers 24, 25 and a cam 26. After the dolly has been wrapped and tied the nozzle 21 is retracted to make way for scissors 34 which cut the thread and are reciprocated by a slider 33a operated by a lever 35. A heated rod 43 holds the cut end of the thread on the end of the electrode that is provided with adhesive until the dolly arrives under a roller 44 which finishes off the fixing of the thread.
