8 Claims,

This invention relates to improvements in machines for cleaning watch works and the like.

In the cleaning oi watches, it is necessary to immerse the works in agitated liquids. Inasmuch as the parts of a watch are very small, it is obvious that the cleaning of watch works by manual means is inconvenient and impractical.

It is therefore an object of this invention to provide a machine for cleaning watch works easily and conveniently. In accordance with my invention, the works are alternately immersed in a liquid and in a drying chamber. In order that the container for the works will be in the exact position for immersion in the various chambers, it is slidably mounted on a polygonal shaft which enables the container to be adjusted to various angular positions directly above the chambers.

A further object of my invention is the provision, in a watch cleaning machine, of a fan arrangement for thoroughly drying the parts being cleaned.

These and other advantageous objects, which will later appear, are accomplished by the simple and practical construction and arrangement of parts hereinafter described and exhibited in the accompanying drawing, forming part hereof, and in which:

Fig. 1 is a perspective view of a watch cleaning machine embodying my invention,

Fig. 2 is a sectional view showing details of the machine, I

Fig. 3 is an exploded view showing the manner in which a container for watch works is connected to the motor shaft, and

Fig. 4 is a plan view of the slidable bracket for holding the motor.

Referring to the drawing, in Fig. 1, the machine is shown to comprise a base I, which supports six containers, 2, 3, l, 5, 6, 1, arranged about a polygonal post 8 extending up from the base, the upper end 38 of the post being cylindric'al. is hexagonal, and is embraced by a collar 9 having a hexagonal aperture 39, the collar 9 having integral therewith a bracket III, which supports an electric motor ll, connected by means of a In the present instance, the post 8 cord l2 to a source of electric current and opera ated by switch 35 or the like. motor H is verticaland has at the lower end thereof a head I! provided with one or more notches l5, which receive lugs I! of a ring l5 having a flange and straps I8 which support a wire mesh basket is for carrying watch works. Attached to the sides of ring l6 are flat springs having bowed-in portions 20 which snap over The shaft I! of.

machine for cleaning the works of watches.

the head I 4 to hold the ring l6 and container l9 on the shaft 13 to rotate therewith.

In operation, the watch works are placed in the container I9, and the container is attached to shaft l3. The collar 9 is then moved up to the cylindrical portion 38 of hexagonal shaft 8 and rotated so that when it again engages the hexagonal shaft 8 the container will be directly over container 2, which contains a cleaning fluid. The container I9 is immersed in the fluid in container 2, and the motor started. After being subjected to the fluid in container 2 for a certain period of time, the collar 9 is raised and rotated to place the container I 9 over container 3 which carries no fluid.

Container 3 is an empty jar, and when the receptacle is lowered into the container 3 and the motor is started, whirling the container IS, the excess fluid which still clings to the parts, from the container 2, is thrown off; 20

After the short time required for this operation, collar 9 is raised and rotated and the container I9 is lowered into container 4. Container 1 contains a cleaning fluid, container 5 is an empty jar in which the fluid which still clings to the parts from container 4 may be thrown ofl, and container 6 has adifl'erent type of cleaning fluid in which the parts are immersed. The final container 1, is used for thoroughly drying the parts as well as for whirling oif any liquids which still cling to the parts. In this container, as shown in Fig. 2, the conical member 2| of the flange strap l8 frictionally engages enlarged portion 22 of shaft 23 to rotate shaft 23 and the fan blades 25. 35

The shaft 23 is supported by a thrust bearing 28in a. recessed plug 21 screwed into a bearing 26, which forms a part of the bottom of container I, which is provided with a plurality of apertures 45 to allow the passage of air there- 0 through, thus thoroughly drying the parts.

Containers 2, I, 6, have various cleaning fluids, and containers 3, 5, I, are drying chambers.

From the above description it will be seen that there has been provided a simple and eflec llzige 45 e hexagonal post 8 enables accurate positioning of the container l9 and motor over the desired fluid containersor drying chambers; and the connection between the shaft is and the disk l6 enables convenient and rapid attaching or removal of the container l9 when desired.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which 55 obviously many embodiments may be constructed, including many modifications, without departing from the spirit and scope of the invention herein indicated and denoted in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is: v

1. In a watch cleaning machine, a base, a post extending up from said base, said post having the upper portion thereof of circular cross section, the remainder of the post being of polygonal cross section, a collar provided with a polygonal aperture corresponding to the polygonal cross section of the post slidably arranged on said post, and being provided with means for selectively contracting the aperture of said collar to clamp the collar on the post or for enlarging the aperture to enable the collar to be freely moved along the post, said collar being further provided with a vertical shaft adapted to support a basket for; watch parts to be cleaned, and a plurality of eontainerspositioned on said base about the post and in alignment with the respective sides thereof, whereby the collar may be rotated on the circular portion of the post and by bringing the collar into engagement with the polygonal portion of the post the basket may be aligned with any predetermined container on the base. v

'2. In a watch cleaning machine, a base, a post extending up from said base, said post having the upper portion thereof of circular cross section, the remainder of the post being of polygonal cross section, a collar provided with a polygonal aperture corresponding to the polygonal cross section of the post slidably arranged on said post and being provided with a vertical shaft adapted to support a basket for watch parts to be cleaned, and a plurality of containers posi-' tioned on said base about the post and in alignment with the respective sides thereof, whereby the collar may be rotated on the circular portion of the post and by bringing the collar into engagement with the polygonal portion of the post the basket may be exactly aligned with any predetermined container on the base.

3. In a watch cleaning machine, a base, a post extending up from said base, said post being of uniform, polygonal cross-section except at the upper portion thereof, said upper portion being of a smaller cross-section than the polygonal portion of the post, a collar provided with a polygonal aperture. corresponding to the polygonal cross-section of the post slidably arranged on said post and being provided with a vertical shaft adapted to support a basket for watch parts to be cleaned, and a plurality of containers positioned on said base about the post and in alignment with the respective sides thereof, whereby the collar may be rotated on the upper portion of the post and by bringing the collar into engagement with the polygonal portion of the post the basket may be exactly aligned with any predetermined container on the base.
