AUTOMATIC WASHER FOR SMALL MACHINE PARTS Filed Dec. 14, 1967 2 Sheets-Sheet 1 K M W 29 INVENTOR 2 HENRY B. EHRHARDT Sept. 2, 1969 H. B. EHRHARDT AUTOMATIC WASHER FOR SMALL MACHINE PARTS 2 Sheets-$heet 2 Filed Dec.
INVENTOR HENRY B. EHRHARDT United States Patent Office Patented Sept. 2, 1969 US. Cl. 134-140 Claims ABSTRACT OF THE DISCLOSURE A washer for small machine parts having a rotatable hollow cage which is adapted to receive one or more baskets in which said parts are placed. A tank containing a washing liquid wherein said cage is supported in an inclined position by a pin and hub arrangement at its lower or bottom end and by rollers mounted in the lateral walls of said tank at its upper or front end. A drive chain, connected between a sprocket on the outward lower end of said cage and a sprocket connected through a gear box to an electric motor supported on the upper end of said tank, serves to rotate said cage.
This invention consists of a rectangular horizontally disposed base supported by four wheels. A rectangular open top tank, in which washing liquid is placed, is secured to the aforesaid base at a predetermined angle and supported by a pair of parallel and spaced vertically disposed supports that extend upward from the top of the base. The just mentioned tank contains two rollers, one on each side in the forward portion thereof on which rotatably rests a rectangular cage in which is removably placed on or more baskets containing the small machine parts that are to be washed. The rear end of the cage is provided with a supporting socket adapted to encompass a fixed pin that projects inward from the inside of one end of the aforesaid tank. The aforesaid socket is also provided with a sprocket which is encompossed by a chain that also encompasses in part a second or drive sprocket. The drive sprocket is mounted on the end of the outwardly extending shaft of a gear box which in turn is mounted on the upper end of one end of the aforesaid tank. The gear box is mounted beside an electric motor to which the gear box is connected by a shaft.
It is the principal object of this invention to provide an automatic washer for small machine parts that will, as its name implies, automatically wash a number of small machine parts in a minimum of time and without further attention once the parts have been placed in the basket in the cage of the machine and its electric motor is activated.
Another object of this invention of an automatic washer for small machine parts is to provide a washer that can readily be cleaned.
Another object of this invention is to provide an automatic washer for small machine parts that is so constructed that the small machine parts to be washed will not be damaged by the action of the rotating parts of the machine nor by its washing liquid.
Still another object of this invention is to provide an automatic washer for small machine parts that can be adapted to contain two or more baskets in which small parts are placed for washing, and still be so constructed as to take up a minimum of space.
The above objects together with other which will become apparent from examination of the accompanying drawings, and from the reading of the following detailed description of this invention, or which may be later referred to, may be obtained by constructing this invention in the manner illustrated in the accompanying drawings, in which:
FIG. 1 is a perspective view of this invention.
FIG. 2. is a top view of this invention; the cage and its rotating chain are removed for reasons of clarity.
FIG. 3 is a sectional view of this invention, taken along line 33 of FIGURE 1. and viewed in the direction indicated by the arrows. The mechanism located in the tank has been removed for reasons of clarity.
FIG. 4 is a rear end view of the cage of this invention.
FIG. 5 is a top view of the cage of this invention.
FIG. 6 is a front view of the cage of this invention.
FIG. 7 is a rear view of this invention.
FIG. 8 is a pictorial view of the basket of this invention.
Like reference numbers indicate corresponding parts in the various figures.
Referring to the drawings, and in particular to FIG- URES 1 and 3, it will be seen that this invention 10 consists of a horizontally disposed flat rectangular base 11 that has each corner supported by a caster 12. A tank 13, that is seen to be rectangular when viewed from the top and triangular in shape when viewed from the side, is mounted on top of the aforesaid base 11 to which it is suitably secured at 14. The tank rests on, and is secured to, the laterally disposed bar 15 that is on top of, and is secured to, the two vertically disposed supports 16 which are mounted on top of the rectangular base 11. Only one of the supports 16 is shown in FIGURES 1 and 3 of the accompanying drawings.
Looking now at FIGURE 3 of the accompanying drawings, it will be seen that the end wall 17 of the aforesaid tank 13 is provided with a pin 18 on which rotatably rests the hollow hub 19 of the sprocket 20 that is secured to the inward end of the cage 21. The cage 21 is fabricated angle irons and a steel or iron ring. The often mentioned cage 21 consists of two crossed angle irons 22, from the center of which outwardly projects the support 23 for the aforesaid sprocket 20. To each outer end of the aforesaid angle irons 22 there is secured one end of the longitudinally disposed angle irons 24 that all have their forward portion encompassed by the metal ring 25 whose periphery rests on two rollers 26 that are secured, one to each inward side of the aforesaid tank 13. From this just described novel construction it is seen that the aforesaid cage 21 will be rotated when the electric motor is activated. This electric motor 27 is mounted on the L-shaped bracket 28 that is secured to the upper edge of one end of the aforesaid tank 13. The electric motor 27 is connected to the gear box 29 whose output shaft is provided with a small sprocket 30 over which rotates the drive chain 31 that encompasses in part the aforesaid sprocket 20 of this invention.
A small parts basket 32, that is rectangular in shape and Whose walls are fabricated from sheet metal having a plurality of openings therein so that the washing or cleaning liquid may flow freely therethrough when this invention is in operation, is removably placed within the aforesaid cage 21, as is clearly shown in FIGURES 1 and 3 of the accompanying drawings when it is desired to wash small machine parts that are placed in the basket. The just mentioned basket is provided with a removable lid 33 that in turn is provided with a handle 34 that is swingably secured to two opposed sides of the aforesaid lid 33 at .35. The locking feature of this novel handle 34 will shortly be described in the operation of this invention. The invention is provided with any desired washing liquid in the aforesaid tank 13. The liquid level is indicated in FIGURE 3 of the accompanying drawings by the reference numeral 36.
The actual operation of this invention of an automatic washer for small machine parts is quite simple when compared to some of the other apparatus used for this purpose. The invention is assembled, as shown in FIG- URE 1, and the desired cleaning liquid placed therein. The basket 32 has the small machine parts that one desires to clean, placed therein and its lid 33 is placed thereon. The basket is now placed in the aforesaid cage 21, as clearly shown in FIGURE 1 of the drawings. The handle 34 is now pushed down to the position shown in FIGURE 3, thereby firmly locking the lid 33 on the basket 32. The electric motor 27 is now turned on in the usual manner, thereby causing the small sprocket 30 of the gear box 29 to rotate. The rotation of the small sprocket 30 turns the drive chain 31 which will now rotate the cage 21 and the basket 32 containing the small machine parts that are to be washed by the action of the washing liquid that is in the tank 13 which will flow in and out of the plurality of openings in the sides and lid of the basket 32. The aforesaid crossed angle irons 22 of the lower end of the cage 21 are so configurated as to dip into and pick up the washing liquid and then spill it into the upper half of the basket 32, thereby adding to the washing action of the washing liquid that is in the aforesaid tank 13 which is provided with a suitable drain plug 37. It is to be realized that the length of the aforesaid cage 21 is such that two or more of the baskets 32 can be placed therein, thereby both doubling and tripling the capacity of the small machine parts basket as well as reducing the cleaning time for a given number of machine parts. It will be noted on examination of FIGURE 3 of the accompanying drawings that the small parts basket 32 is held in the position shown in phantom lines by means of the handle 34, above the liquid that is located in the aforesaid tank 13. This position of the parts basket 32 will permit any liquid that is in the basket to drain down from the same back into the tank 13. The cage 21 and the basket 32 can be rotated while the basket is above the liquid, thereby speeding up the liquid drainage from the basket.
This novel invention can be particularly useful around the disassembly and/or assembly line of internal combustion engines that are being repaired or reconditioned since the washer can be pushed up next to the engine being worked on.
It is to be understood that detailed changes in the construction of this invention can be made as well as modifications in its overall design.
