5 Claims.

My invention relates to. improvements in depositing machines for use in making candy, confections, and the like. It comprises an auxiliary feeding hopperwhich can be inserted into the usual feeding .hopper of a depositing machine, with detachable pipes being connected thereto and vto the lusual outlets from the main hopper whereby confectionof different colors or kinds can be simultaneously deposited in pre-prepared molds.

I am aware that machines of this type have heretofore been used in the art, but they are unitary structures and adapted to do only one particular job. These depositing machines are quite expensive and in many instances to have a machine for one special purpose is prohibitive insofar as the cost of the machine is concerned and adds materially to the cost of the confection to be manufactured. With my improved construction I am able to'use the standard machine for depositing candy or confection of one kind in single units, vand by adding my attachment thereto the machine is converted so that multiple kinds of confection can be deposited simultaneously inthe same mold. When desired, the attachment is removed and the depositing machine utilized for the single purpose for which it was loriginally intended. In this manner the purchase of additional machines, which of necessity must stand idle for a good portion of the time when not making special kinds of confection,l is unnecessary, and the investment expense of manufacture is materially reduced,` door space' is saved, additional labor costs are avoided, and the expense of production of the particular product is also materially reduced. v

Another and further object of my invention is the provision of means which can be easily and quickly attached to the hopper of an ordinary depositing machine as well as removed therefrom, and the parts of which are simple to manufacture and easy to clean in preparation for use and after they have been used.

These and other objects of my invention will be more fully and better understood by reference to the accompanying drawings, in which- Figure l is a top plan View partially in section of the standard depositing machinewith my invention applied thereto;

Figure 2 is a rear View of the pump with plate attached, forming a part of the usual standard machine; f

Figure 3 is a transverse sectional View of the machine with the auxiliaryI hopper attached;

Figure 4 is a top plan View of a depositing machine showing means for supplying three diiferent kinds of confection to the depositing pump; and

Figure 5 is a transverse sectional view of the 5 apparatus illustrated in Figure 4.

Referring now specifically to the drawings and in which like reference charact'ers refer to like parts throughout, a main hopper Ill is shown having a curved bottom II, end walls I2 and I3, lo and a fro-nt plate I4 usually of cast material, the balance of the hopper being made of sheet metal of any preferred form. 'Ihe plate I4 at the bottom thereof has a pump casing l5 extending throughout the length of the hopper plate I4 upon which cylinders IE are mounted, having pistons Il therein, the combination acting as pumps for depositing the material in fluid form in pre-formed molds, and with a plate I8 at the rear side thereof having openings I9, I9 therein which are in register with outlet openings in the front wall I4 of the hopper III. All of these parts are of Standard construction for depositing machines and are used for depositing fluid material in the making of candy and various 25 confections in predetermined quantities, usually in pre-formed starch molds which are advanced on suitable carriers underneath the outlet spouts of the pumps in step by step relation and in synchronism with the operation of the pumps, all of which is old and well-known in. the art and it is not deemed necessary to here illustrate or describe.

The machines hereinabove described are adapted for making only one kind or one color of a particular candy or confection at a time. If it is desired to make a two-color piece of confection or a confection composed of "two kinds of materials it has been necessary heretofore to use a machine with a plurality of discharge spouts 40 with the hopper separated by partitions or the like to contain the materials ultimately deposited in the molds.

My improvement comprises an auxiliary hopper 20 of a size and shape to fit inside of the main hopper I0 while still allowing suicient space for material to be placed in the main hopper Il). The auxiliary hopper 20 is provided with a handle 2| for convenient handling and with

brackets

22, 22 which engage the upper edge of the end Walls I2 and I3 of the main hopper I0 so that the auxiliary hopper 20 is held suspended in the main hopper Il). The hopper 20 is somewhat narrow at the bottom so that when filled or partially filled with material it will bev suspended in a vertical direction in the main hopper I0, as shown particularly in Figure 3.

Outlets ports in spaced relation with each other are provided in the forward front Wall of the hopper 20, to which

flexible tubes

23, 23 are connected. These tubes 23 have metallic end members 2li, 2li with

collars

25, 25 spaced inward from the ends of the tubes a slight distance and securely fastened to the tubes 23.

Gaskets

26, 26 are provided which contact against the outer front wall of the hopper 20 and the inner side of the front wall I@ of the main hopper I0. The ends of these tubes 23 project through the ports in the auxiliary hopper 20 and the ports in the front wall l of the main hopper, and into the pump casing l5. These tubes, being flexible, are also expansible and when placed in position are slightly compressed so that the gaskets 26 are held rmly against these walls without danger of the material leaking therefrom, and form tight openings from the outlet ports to the pump. The ports in the auxiliary hopper are preferably in register with each alternate port in the row of outlet ports in the front wall I4 of the hopper Il), and in this manner one kindv of confection is supplied to the pumps from the main hopper l!) while another kind is supplied from the auxiliary hopper 20.

In pre-forming the molds for the reception of the deposited material making up the finished piece of candy or other confection, I prefer to make the receiving recesses in the molds slightly elongated so that each mold passes under the outlet spouts of two pumps. In this manner the material is deposited somewhat toward the end of each of the pre-formed receiving recesses in the molds and flows outward toward the ends and inward toward the center with a blending of the material at the center of the mold. Thus, if it is desired to form a confection, such as a piece of candy, with an orange color at one end and a lemon yellow at the other, one kind of material is placed in the main hopper and the other placed in the auxiliary hopper and simultaneously deposited in the mold, so that as it flows into the mold the final confection is a two colored piece, the ends of which are distinct as far as the original colors are concerned, while there may be a slight blending along the middle line of the piece of confection but insufficient to destroy the clear line of color distinction.

In Figures 4 and 5 is illustrated a modified form of my improved invention. An auxiliary hopper 2'! is provided of substantially the same shape and contour as the hopper 20 heretofore described, but with a middle wall 28 extending longitudinally thereof whereby the hopper 2T is divided into compartments 29 and 38. The wall of the hopper 2 has a plurality of spaced outlet ports therein in alignment with pairs of the spaced ports in 'the front wall Hi of the main hopper, while each alternate discharge port leading from the hopper 2 has a short tube 3| spanning the distance from the front wall of the hopper 2l' to the bottom of the partition 2B, so that material from the compartment 3G flows through the short fixed tubes 3l and through the

outlet tubes

23, 23 to the pump frame l5. The material from the compartment 29 flows directly into the outlet tubes 23 and is conveyed therethrough to the pump casing l5. Three compartments are thus provided, two in the auxiliary hopper 2 and one in the main hopper l0 so that three different kinds of material or three different colored materials of the same kind and character can be placed in the three compartments of the hopper and simultaneously deposited in the starch molds in the regular operation of the machine. In this fashion a three colored piece of confection can be easily and quickly produced, such as red, white and blue for sale around the Fourth of July, and other confections for other seasonable times of the year or for regular sale if so desired.

The operation and use of these auxiliary hoppers will be readily understood from the foregoing description, in that when it is desired to produce a single confection made up of two materials or two different colored materials, the hopper illustrated in Figures 1, 2 and 3 may be used and the materials kept separated until they are finally deposited in the molds as they pass underneath the discharge spouts of the pump. When a run of this material is finished the auxiliary hopper may be removed and the machine continued in use for depositing a single kind or single color confection, as may be desired.

In the form illustrated in Figures 4 and 5 the operation is precisely the same except that the hopper 2l is placed inside the main hopper l0, with the discharge spouts suitably connected to the outlet ports in the main hopper I0 in any way that may be desired, it only being necessary to provide that the molds are sufficiently large to extend under at least three of the discharge spouts from the pump.

The auxiliary hoppers and the connecting parts can be added to or removed from a machine in a short space of time and easily kept clean for use any time that may be desired.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may suggest or render expedient without departing from the spirit or scope of my invention.
