- 5 claims. A(C1. 141-1) The invention relates to cleaners for watches, jewelry and the like, of the type including a rotary basket or container in which a watch movement or watch or watch parts, etc. may be placed for rotation in a bath of cleaning fluid.

An object of the invention is to provide a watch cleaner of the character described wherein a positively induced flow of cleaning fluid is produced completely and uniformly throughout the entire interior of the parts container, whereby the fluid is caused to pass over and around and through each and every part placed in the container, regardless of its position in the container.

Another object of the invention is to provide a Watch cleaner of thev character above wherein the parts are properly supported in segregated position in the container and `held in position while subjected t-o a relatively high. speed of rotation and to the traversing iiow of a substantial body of cleaning fluid.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forth `in the claims.

Referring to said drawing:

Figure 1 is a vertical sectional view -of a watch cleaner constructed in accordance with the present invention.

Figure 2 is a side elevation of the several parts of the watch cleaner shown in detached position.

Figure 3 is a cross-sectional view of the watch cleaner taken substantially on the plane of line 3-3 of Figure 1. Y

Figure 4 is a vertical sectional View of a watch cleaner showing a modified form of construction.

Figure 5 is a cross-sectional View of the form of the invention illustrated in Figure 4 and is taken substantially on the plane of line 5--5 of Figure 4.

The watch cleaner of the present invention consists briefly in a container adapted for submersion in a bath of cleaning fluid and for rotation at a relatively high speed therein and formed with a perforate wall traversing the axis of rotation of the container, and centrifugal pump means carried by the container in axially spaced relation tothe aforementioned perforate wall operable upon rotation with the container to draw iiuid through the wall and uniformly and completely through the interior of the container.

With reference more particularly to the accompanying drawing, the cleaner of the present invention therein depicted -comprises a member II which is adapted for submersion and rotation in a bath I2 of cleaning fluid, as contained in a suitable jar or container |13. Desirably, some suitable means is provided in the jar for preventing the liquid from whirling therein during rotation of the member in the bath. The member I I is ofgenerally cylindrical form and is composed. of upper and lower sections I4 and I6 which as here shown, are provided with aligned and'comf municated interior chambers I1 and I8 respectively. The lower section IS is formed witha circumscribing side wall I9 and a perforate bottom 2l, here in the form of -a screen mounted across the open lower end of the wall I9. The

upper end 22 of the lower section isv preferably left open and is detachably secured to the lower end portion 23 of the upper section by fitting of the upper extremity 22 of the lower section firmly against a shoulder 24 on the portion 23, so as to seal the sections in engagement and to provide a smooth continuous closure at the top of the lower section preventing any small parts contained therein from lodging between the connected sections.

The detachable connection between the sections is here provided by a plurality of circum- 4 ferentially spaced radially extending lugs 26 on the upper outer surface of the wall I9, and which are received in circumferential lug engaging slots 21 provided in the base portion 23 of the section I4, which base portion as here shown, surrounds and embraces the upper end extremity of the wall I9. The lugs and guides are so spaced circumferentially as to enable a quick and ready attachment of the sections by engaging the sections longitudinally to align the lugs and guides and then rotating the sections relative to each other so as to engage the lugs and guides. Preferably, the lugs or the guides are slightly tapered so as to. cause a firm wedged engage-ment of the same to hold the sections in attached position. As here shown, both the lugs and guides are slightly tapered for this purpose.

The base portion 23 of the upper section fis here formed as a ring across the top of which is supported a perforate bottom for the section here in the form of a screen 28. Also the side wall 29 of the upper section is perforated and is here shown formed of a screen supported between the base 23 and an elevated ring 3| adjacent the top of the section. A cover plate 32 is mounted across the top of the upper section and supported on the ring 3| by means of a bayonet connection including circumferentially spaced lugs 33 on the ring member and guides 34 on a circumscribing depending part 36 of the cover substantially similar to the lugs 26 and guides 21 above described. Means for rotating the device may be conveniently attached to the cover plate 32 and as here shown, the latter is provided with an axial recess 31 in which is fitted one end of a drive shaft 38, and which is held iixed therein by means of a screw 39.

As an important feature of the present invention I incorporate in the device a centrifugal pump means which is operable upon rotation of the device in the fluid bath to produce a positive flow ofiiuid completely and uniformly through the interior chambers of the device. Such pump means has been here incorporated in the upper chamber |1 and is formed of a plurality of radially extending blades 4| which extend outwardly from a center hub portion 42 to the circumscribing screen 29. Preferably, the blades also extend for the full vertical height of the section between the screen 28 and the under-side of the cover plate 32, so as to divide the upper chamber into a plurality of circumferentially spaced compartments 43 which are adapted for receipt of the smaller watch parts to be cleaned. It will be understood thatupon rotation of the device, the blades 4| will cause a centrifugal movement of iiuid outwardly through the compartments and will draw such iiuid upwardly through the lower compartment I8 by way of the perforate Walls 2| and 28. Due to the fact that the fluid is confined to a vertical ow through the interior of the lower chamber I8 by reason of the imperforate side wall |9, there is a full and uniform passage of fluid through the lower chamber thereby contacting every part mounted therein, regardless of its location in the chamber. Preferably, in using the device, the larger watch parts are mounted in the lower chamber I8 and some of the parts will substantially fill the width of the chamber, so that the fluid is caused to pass across such parts and through openings therein in nding its way up to the upper chamber. Also in order to cause the iiuid to flow through the full vertical height of the compartments 43, I extend the imperforate base 23 above the screen to occupy a substantial part of the vertical dimension of the compartments, whereby the fluid is forced upwardly in the compartments to the screen 29.

A modified form of the invention has been illustrated in Figure 4, wherein the lower `section I6 of the device is made somewhat larger in vertical dimension than in the first embodiment and is provided in the base thereof with a spider 44 for dividing the lower chamber into a plurality of compartments 45 for carrying the smaller watch parts. The upper section |4 of this embodiment is formed of upper plate 46 and annulus 41, which are attached respectively to a drive shaft 38 and to the upper end of the lower section I6 in the manner described in connection with the preferred embodiment. Screens 2| and 28' mounted across the lower end of the section |6 and across the lower end of the upper section |4 serve to enclose the chamber in the lower section. In this form of the invention a plurality of vanes 48 are mounted between the members 46 and 41 and extend radially with respect to the central axis of rotation of the device, so as to cause upon rotation of the device drawing of cleaning fluid upwardly through the chamber in the lower compartment, and discharge of such fluid outwardly between the members 46 and 41. In this form of the invention, as in the preferred embodiment, the fluid flow is positively induced and the fluid is drawn uniformly and completely through the interior of the parts chamber, so as to thoroughly clean the parts mounted therein, regardless of their position in the chamber. e

As will be readily evident, the cleaner of my invention may be used for drying the watch parts by operating the same in dry or heated air after the cleaner is removed from the cleansing iiuid.
