20 Claims. 1

This invention relates to a mechanism for use in cleaning various articles or devices which have been utilized for various purposes but require thorough cleaning before being used as containers for various products, especially those utilized in food products such as meats of different kinds which carry thereon more or less fat. When articles having grease thereon are to be cleaned, I have found that the ordinary methods of procedure such as hand operations are slow and expensive and not always perfect.

The mechanism that is to be described herein has been especially designed to clean metal boxes in which hams that have been cooked and the bones removed, are compressed thereinto for delivery purposes and these boxes become quite greasy especially on the inside. Whil e the mechanism is especially adapted for this use it is not limited to this but is adaptable for cleaning other articles or things as will be readily seen from the detailed description which follows. The cleaning fluid used may be varied to suit conditions and the machine will handle all kinds.

Referring now to the details wherein like numbers refer to corresponding parts, I generally denotes the framework having side cover plates the one on the opposite side from Figure 1 being entirely removed to show the interior part. The framework may be considered as having sections 3 and 4 one above the other, the bottom section 4 has at the incoming end a cleaning chamber 5 and at the opposite end a rinsing chamber 5. As will be readily seen from Figure 36, the washing or cleaning liquid is taken into the chamber 5 through a pipe 1 and valve 8. Chamber 5 preferably contains heating coils 9 to which steam is supplied by pipe l and valves H and I2. The chamber 8 is likewise provided with heating coils I3 to which steam is supplied by the pipe in and valve 14, water being supplied by the pipe I and valve I 5. The steam exit pipe I1 is connected to pipes 9 in the chamber 5 and a corresponding pipe l8 to the coils I3 in chamber 5. The chamber 5 has a drain pipe I9 controlled by valve and the chamber 5 a drain pipe 2| controlled by valve 22. Connected to the chamber 5 is a pump 23 and to the chamber 6 pump 24, both pumps being driven by a motor M.

Mounted in the upper longitudinal compartment o.the framework is a conveyor 25 which is supported at the intake end on a suitable pair of wheels 25 connected by shaft 21 while a similar pair of spaced wheels 28 are connected by shaft 29, it being understood that the shafts 21 and 29 are suitably supported on theframework of the machine. The conveyor 25 is made up of a plurality of similar side links 30 which are held together by pivot studs 3|. Connected beween the side links 30 in spaced relation are a plurality of cross bars 32, one to each pair of links. Fastened to these cross bars 32 are fingers 33 which are preferably adjustable along the bars 32 by a clamping screw 34 as shown in Figures 14 and 18. It will be seen from Figures 13 and 14 that the fingers 33 extend from one bar 32 to the next adjacent. As shown in'Figure 14 the fingers 33 overlap at 35 the next adjacent bar 32 and one end of the fingers 33 is bent around the bar 32. In Figure 17 the end of the finger terminates at 35 in clearance space to the bent over end 31 of the finger 33. Either form of construction may be utilized but in either side frame members 43 it being understood that there is one of the members 43 on opposite sides of the chamber in which the conveyor is located.

The conveyor is driven by motor m (see Figures 3 and 4), which is connected by a belt drive 44 to a speed changing device 45 which is connected by a belt 45 to a pulley 41 carried on ashaft connected to a differential gearing in a box 48, the output shaft 49 which carries a chain drive 53 that is connected to a pulley 5| carried by the shaft 29 on which the operating wheels 28 of the conveyor are mounted. Also associated with the differential gearing 48 is an output shaft which is connected with belt 52 of a suitable type which drives the shaft 53 on which is mounted a disc 54 which may be provided with a plurality of holes into one of which the pin 55 may be inserted to change the throw given the rod 55 by the disc 54. The rod 56 is connected to an arm 51 that is adjustably fastened as by a set screw 58 to a pipe 59 which extends longitudinally through the cleaning and rinsing compartments through which the conveyor 25 carries. One of these pipes 59, divided into two sections 59a and 59b is located in the upper part of the mechanism (see Figure 2) and another one 80, is divided into two sections a and 50!) below the conveyor. The pipe 59 is divided into the two parts above mentioned by what 1 term a neutral section N, that section over the cleaning compartment which is over the chamber 5 being section 59b while the other portion of the pipe 59a is over the rinsing chamber 5. As shown in Figure 20 the pipe 59 is divided in'the neutral section by a blind union 6|, so as to keep the cleaning liquid C separate from the rinsing liquid R, it being understood that the cleaning liquid is of a suitable nature which will dissolve or take up grease or other dirt that may be in the articles going through the machine on the conveyor 25, while the rinsing liquid may be clean water, both liquids being heated by steam coils 9 and I 3 as heretofore explained. I prefer to have a single pipe with the blind union 5| in preference to two separate pipes one forthe cleaning liquid and the other for the rinsing which is the simplified construction as will be readily seen from what follows. Instead of the arm 51 being fastened alongside of the blind union 5| as shown in Figure 20 the arm 51 may be placed directly on or made a part of the blind union so that as the motor m is operated the crank disc 54 through the rod will oscillate the shaft 59--59a. As will be seen from Figure 2 there is a companion disc 54a having a crank pin 55a connected to the pipe Gil-80a in the same manner as in the Figure 20.

By reference to Figure 36 it will be seen that the pipe 82 comes from the pump 23 and lawnnected to the pipe end 59b which is located above the articles going through on the conveyor and also to the pipe end which is below the articles going through on the conveyor. While pipe 83 coming from the pump 24 is connected to the pipe end 59a, as well as to the pipe 'end 50a.

Referring now to Figures 21-33 the means for delivering the cleaning and rinsing liquid from the pipe ends 59b59a, 60b and 60a will be seen.

A description of the distribution from one of the pipe lines will apply in a general way to all of the Figures 31-33. Referring first to Figures 21 and 36 it will be seen that there is a plurality of nozzles distributed longitudinally along the pipe ends 59b and 59a which are connected to their respective supply pipes 62 and 63 by nipples 66 on which is rotatably mounted a suitable coupling 61 to which the nozzle 68 is attached. The end of the nozzle 69 as shown has an oblong hole for spreading out the liquid as it is forced through the nozzle 68, through suitable unions 64 and 65, whereby the whole pipe may be turned or oscillated to a desired angle by means of the rod 56 which is connected to the arm as has been described.

Loosely mounted on the nozzle 58 is a collar to which is attached a rod II that passes through a clearance hole 12 in the end of an arm 13 that is pivotally mounted at 14 to a clamp, the parts of which are generally referred to by I5. The clamp is adjustably positioned on a support member 18 which is preferably in the form of a hollow pipe that extends longitudinally along the opposite sides of the framework and fastened thereto in any satisfactory manner. As shown in Figure 2 the nozzles 68 are shown for simplicity in individual arrangements along the length of the pipe 59b-59a but in Figures 21-33 theyarev shown as they are preferably utilized in pairs, but they may be arranged individually on opposite sides in spaced relation on the supply pipe.

By reason of the control connections just described, as the supply pipes 59b, 59a are oscil lated by the rod 56 and arm 51 the nozzles are caused to turn through a multitude of angles as will be seen from these Figures 21 to 33. This angularity being controlled by the rod H and the adjustment along the support pipes 16. In these different Figures 21-22 it has been endeavored to show from actual movements of the nozzles just what takes place in the distribution of the liquids in the cleaning-compartment as well as in the rinsing compartment, these two c'ompartments being divided by the neutral space connection which is divided by the screens 19 and 80 these screens being flexible and made out of water-proof material and suspended from the framework at the points BI and 82. These screens prevent the cleaning liquid from mixing with the rinsing liquidand as these liquids pass down through the sieves 83 and 84 which are slidably mounted in the framework as shown in Figure 2, the liquids pass back into their respective chambers 5 and 6. Whatever vapor may get past the screen 19 to the articles going through on the conveyor which moves the screens out of their vertical position, is taken up by an exhaust pipe P which may be equipped with an exhaust fan. It will be noted from Figure 36 that the sieves 83 and 84 are positioned in slightly slanting surfaces 85 and 86 that extend inwardly from the opposite ends of the framework, these surfaces terminating in upwardly inclined portions supported by a projection 81 formed by inner sides of the chambers 5 and 6. The article receiving end of the mechanism is provided with a chute 88 fastened at one end to a support 89 by one or more arms 90, while the opposite end has lugs 9! on opposite sides to receive holding studs 92. This end of the bottom part of the chute 88 has an upwardly extending rounded end 93 which sets in a recess in the shelf 94 that is fastened to the end of the framework of the machine. This rounded end 93 while acting as a stop for a box 3, allows the box to be easily moved upwardly over e rounded surface onto the conveyor (see Figures 57). As the conveyor moves in the direction oi t l:e arrows in Figures 5 and 6 the stud 38 passes pwardly within the article which in this case is a metal box B 'and which moves it out of the stop position as shown, up into the conveyor and into engagement with a screen or curtain 95 which is utilized to prevent liquid, which is being sprayed out of the nozzles from coming out of the machine. As shown in Figure 5 the second box has been moved down into stop position and in Figure 6 another stud 38 is about to engage it to move it onto the conveyor. The different steps in these movements will be clear from inspection of Figures 5, 6, 7 and 8 without further eescription.

The discharge end of the mechanism is shown in Figures 9, 10, 11 and 12 and comprises a chute 95 having one end fastened to the delivery end of the machine with its posite end as shown in Figure 2 attached to a sup rt member 91. Preferably an adjustable brace member 98 is utilized as shown in Figure 2. 'Pivotally connected to the support member 91 is a lever 99 held by a spring so that the downwardly projecting end of the lever 99 is held away from the spring contact member l0l. Normally the spring llll carries a contact which is engaged by a cooperating contact H12 on a spring I03. This pair of contacts 102 is for controlling a circuit through the motors M and m as shown in Figure 37. The motor M has a switch I06 mounted in a switch box which preferably contains a fuse for the circuit. The switch I06 is connected to a plug-in socket I04 to which the main power supply is connected. Leads run from the switch I06 which is preferably of the four-pole type to the motors M and m and from the latter direct to the switch contact I02. The motor M is connected to a push button switch I06. This arrangement as shown in Figure 37 allows the small motor m to start into operation which will move the conveyor 25 and the oscillation of the pipes 59b59a, 60b and 60a but no liquid will come through the nozzles until the pump motor M is started by operating the switch I06. A pair of plug-in contacts I05 are furnished so that extension cords may be fastened thereto'for interior inspection of the machine before the motor M is started. As the articles, in this case boxes B come down the chute 96 they push aside a screen or curtain H5 which serves the same purpose as the screen 95 does at the opposite end of the machine. As the conveyor brings the boxes B to the discharge end of the machine the ing 38 moves the boxes B onto the chute 96 and as succeeding boxes come along they push the boxes down the chute. An operator is presumed to be in attendance to take the boxes B off the chute 96 as they come off the machine but in case the attendant is called away for some reason when the chute becomes filled the pressure on the last box coming from the machine will Push the line of boxes downwardly so as to operate the lever 89 and cause it to operate the spring ISI and open the circuits to both motor M and m as shown in Figure 37, thereby stopping the conveyor as well as the motor forcing the liquid through the nozzles. In Figure 35 I have shown an alternate arrangement by which the chute 96 may have an extension I01 connected thereto with a conveyor belt I08 to carry the article being washed, out to-a.

place of deposit. In this figure the power drive is obtained by the belt I08 to a pulley carried on a shaft I09 which in turn has a pulley driving a belt H that passes over a pulley ill fastened to shaft I I2 that carries anadditional pulley that is fastened to the shaft H3 that carries pulley I 14 that drives the belt I08.

By reference to Figure 1 it will be seen that both of the chambers 5 and 6 have gauges g and g for showing the height of liquid in each chamber. Likewise, the temperature of the liquids in the two chambers are given by the thermostats t and t for controlling the temperature of the liquids in the cleaning tank and rinsing tank. In Figure 34 I have shown a separate view of the union between the nipple coming from one of the liquid supply pipes. This union is of the Chiksan type in which a ball bearing is utilized between the nipple 66 and the swivel elbow which I have previously referred to as a suitable coupling. The gaskets which may be used at the union are not shown, also in Figure 36 the neutral space N is illustrated by the two broken lines, but the curtains such as 19 and 80 as shown in Figure 1 are not shown and neither are their companion curtains below the conveyor 25 shown.
