WASHING APPARATUS FOR DISHES, &o.
Specification of Letters Patent.
Patented 0012.15, 1918.
Application filed December 12, 1917. Serial No. 206,755.
To all whom it may concern:
Be it known that I, BENJAMIN F. SPARR, a citizen of the United States, and a resident of the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Washing Apparatus for Dishes, &c., of which the following is a specification.
Although applicable to the Washing of various articles my improvements are especially adapted for embodiment in dish washing machines and the like, in which rapid and thorough cleansing is a desideratum. Heretofore gravity sprays have been resorted to' in such apparatus to effect the initial removal of the extrinsic matter and the subsequent rinsing of the articles, but that method is lacking in power and efiiciency. One of the objects of my invention is to augment the impact of the sprays of water used for both purposes and at the sam time to provide for the regulation of force in accordance with the character and require- I ments of the articles under treatment so that fragile and delicate objects may be subjected to pressure less strenuous than that which can safely be applied to stronger and coarser objects. Another object of the invention in this connection is to control the speed of treatment manually by means of a crank by which the feed of the work carrier may 'be accelerated or retarded, as found most expedient. Another feature of the invention is the spraying of the articles simultaneously from below as well as from above so as to render the cleansing more rapid and effective,the invention consisting in the combination and arran ement of parts described and claimed specifically, the operation of which will be hereinafter more fully set forth.
In the accompanying drawings,
Figure 1, is a vertical longitudinal sectional elevation of apparatus embodying the essential features of my invention, taken upon plane of line 1-1, Fig. 3;
Fig. 2, is a section taken upon plane of line 2-2, Figs. 1 and 3;
Fig. 3, is an end elevation of the apparatus;
Fig. 4, is a sectional elevation taken upon plane. of line 4-4, Fig. 1, but on a larger scale.
The elongated tank T, is sup orted on standards a and is divided by a transverse partltion 25', into the compartments T, and T The outer ends of these tank compartments T, T are each provided with a hinged cover t the free ends of which rest normally on stops t Between these outer end covers Z is the wash chamber C, closed at the top and sides, but communicating below with the tank compartments T, T over the inner ends of which the wash chamber C, extends as shown more particularly in Fig. 1.
The ends of the wash chamber C, are provided with doors a, a, hinged so that they may be swung into horizontal position to act as end platforms or tables to facilitate the handling of the articles to be treated. In the drawings these doors are fulcrumed on the shafts a, a, and are formed with rests o, c, which contact with the tank covers t when the latter are closed and the doors a, a, are open, as in Figs. 1 and 3. The doors 0, c, are also preferably formed with side members or wings a 0 which act as guards and fenders when the doors are open and in use as tables or platforms.
The shafts a, a, mounted transversely, one at each end of the wash chamber C, carry pulleys a, a, over and between which endless carriers 6, I), travel, said carriers being also supported medially by idlers a (1 A crank a secured to one of the shafts a, affords means for manually driving the endless carriers 6, b, which may consist of parallel twin belts, one on each side of the wash chamber C, on which open work trays or baskets (containing the articles to be washed) may be placed, thus leaving the space between the belts b, 6, free for the passage of the cleansing fluids; or any other form of open work carrier may be substituted that will admit of the requisite flow and circulation of cleansing fluids.
The compartment T, of the tank contains the primary cleansing fluid solution such as water and solvent compounds dissolved therein, to facilitate the removal of grease and other foreign substance from the surfaces of the articles to be cleaned,-the level of this primary cleansing fluid in said compartment T, being determined by the drain stand pipe 03, which conducts the overflow through the discharge pipe (1, to the waste or sewer pipe 03 n ike manner a drain stand pipe d, in the other compartment T,
of the tank determines the level of the.
rinsing liquid therein, said drain stand pipe 1 d, communicating with the sewer or waste a drain d",
- mary pipe d, through the medium of the discharge pipe (i The bottom of each compartment of the tank is also provided with controlled in each case by a valve 0Z sald valves connecting respectively with the discharge pipes 01, and d, as shown particularl in Fig. 1.
P, is a uid pressure pipe provided with a control valve Connected with this fluid which is the utilization of the fluid pressure to suck in and force the solution from the compartment T, to and through the supply pipe 0, and its branch e, to the pressure shower pipes e e posltioned 1n the upper part of the wash chamber C. Any desired number of these shower pressure pipes e, 0 may be provided according to the size and capacity of the apparatus and the particular purpose for which it is intended. Manlfold ejectors E, E, are also attached to the transverse pressure pipe 1)" in the primary compartment T, formed each with a serles of ejector nozzles 6, similar in construction and operation to the ejector E, shown in Fig. 4:- This series of'ejector nozzles project upward solution against the under sides of the articles presented above them by the work carriers b, 6.
E is an ejector like unto that illustrated in Fig. l, but situated in the rinsing liquid compartment T and mounted on the pressure pipe p contained therein. In this case the ejector E not only communicates with a stand pipe e a transverse branch 6 and its series of pressure shower pipes 6 6 but also with a lower transverse pressure feed pipe a carrying a series of ascending spray pipes e which project the rinsing liquid upward against the under portions of the articles immediately above them on the carriers 6, b, at the same time that the pressure shower pipes 6 precipitate said rinsing liquid upon the upper sides thereof, thus insuring a thorough cleansing of the articles treated. The meeting of the opposed pressure sprays in the case of the primary cleansing liquid as well as in the case of the rinsing liquid renders both operations speedy and effective.
' The fluid pressure supplied through pipe and precipitate the cleansing P, may be either water,steam or air pres- 5 of liquid from the compartments T, T in I proportion to'the pressure in a manner well known, and thereby effecting a forceful circulation of both the primary cleansing liquid and the rinsing liquid in such manner as to effectually prevent clogging of the spray or shower orifices by grease or dirt,a source of difficulty inherent in apparatus in which gravity alone is relied upon to spray the articles treated. h
The control of the feedof washable material to the pressure jets by means of the crank a is also an important factor in attaining perfection of result as the articles may .be advanced continuously or intermittently, slowly or rapidly, according to circumstances and requirements. Furthermore the passing of the articles through a path in which liquid under pressure is caused to impinge against them sidesowing to the meetmg and concentration of the opposed sprays in said path, is an important and distinctive feature of my invention and one that renders the apparatu's-efiicacious. It also enables me to attain a maximum of result and output within a-minimum of space, since the whole arrangement is simple and compact,-the 'opposed sprays insuring the cleansing of the zftrtiicles in a small area and short length of When the use of relatively large quantities of water is desirable water under pres sure may be supplied to the ejectors; when very hot water is re uired, steam pressure may be found prefera 1e; or when working under normal conditions with hot water, compressed air may be used for thepurpose,or any combination of these fluid pressures may be resorted to in certain emergencies.
I have herein shown my pressure sprays as operating andopposed vertically al though it is obvious that they might be arranged horizontally or at any intermediate angle between horizontal and vertical without departing from the spirit and intent of my invention in this respect.
What I claim as my invention and desire to secure by Letters Patent is,
Washing apparatus of the character designated, comprising a tank compartment to contain a cleansing fluid, a transverse pressure pipe within said compartment, manifolds connected therewith and extended lengthwise of the tank and arranged to be practically on all immersed in the cleansing fluid, a multifluid in opposite directions upon'the articles plicity of ejector nozzles carried by said to be cleaned, and an ejector connected with manifolds and terminating above the fluid said supply-pipe.
level, a supply pipe rising from said trans- BENJAMIN F. SPARR. verse ipe, a plurality of shower pipes con- Witnesses: necte with the supply pipe, said ejectors GEO. WM. MIATT,
and shower pipes arranged to spray the DOROTHY MIATT.
