United States Patent SECTIONAL DISPENSING RECEPTACLE FOR SMALL PARTS Charles W. Doepke and Otmar L. Moehringer, Cincinnati, Ohio, assignors to The Charles Wm. Doepke Mfg. Co., Cincinnati, Ohio, a corporation of Ohio Application March 1, 1954, Serial No. 413,194

8 Claims. (Cl. 222-129) This invention is directed to a receptacle for storing batches of small parts, such as nuts and bolts, and for feeding the parts by gravity to a dispensing position where they may be dipped out conveniently. The invention is addressed in particular to a dispensing receptacle of sectional construction which may be utilized either as a single unit or erected in multiples to store and dispense an assortment of parts according to the particular requirements of the various industries.

The receptacle is intended particularly for use in factory operations which involve the handling of parts, for example, along an assembly line, where a selection of parts must be presented to the workman in a position convenient for use. In assembly operations of this kind, it is important that the selection of parts he maintained in a given position to eliminate lost motion and mistakes; it is equally important that the supply of parts be maintained in sufficient quantity at all times, otherwise the assembly procedure is interrupted.

In most instances, the workman or assembler dips manually into the receptacle for the needed part or parts, for example, a bolt and nut of a particular size, together with the required washers. For most efi'icient operation, it is essential that the batch of parts of each grade or kind be located in a position distinct from the other grades, allowing the workman to reach instinctively for the required part as it is needed. In most operations, the parts are used up at a fairly rapid rate; therefore certain workers are charged with the responsibility of supplying fresh batches of parts to the assemblers as the supplies are exhausted.

Briefly, the present invention contemplates a vertical rack structure for supporting one or a plurality of hoppers or bins which are demountably cradledin the rack, each hopper being suspended in an inclined position and having an open spout at its lower end into which the parts flow by gravity to a dispensing position. The rack structure comprises a base and sectional rack or holders arranged to be interfitted vertically upon the base and upon one another in multiples. The individual hoppers, one for each holder and one for the base, are cradled one above the other within the base and within each holder, the lower portion of one hopper overhanging the upper portion of the hopper next below it. In this position, the open spouts of the hoppers are sustained in horizontal tiers spaced one above the other, with the parts in them available for convenient selection. For supporting the hoppers, the upper end of each hopper includes bails which act as pivot bearings. The pivot bearings interfit open notches or slots formed in the base and in the holders; thus, the several hoppers may be demounted for refilling simply by lifting them from their holders. The hoppers are of identical construction and, if desired, reserve hoppers filled with batches of the various parts, may be kept at hand to replace the empty hoppers as required. In other operations in which the time element is not so critical, reserve hoppers need not be used; in-

2 stead, the empty hoppers may be demounted, refilled and then replaced on the rack.

The sectional construction of the rack assembly and interchangeable hoppers, lends a great deal of flexibility to the structure since any number of holders, within practical limits can be erected one upon another to suit the requirements of a given assembly station. If required, additional rack assemblies may be attached alongside one another in battery formation for added capacity. On the other hand, if an individual dispenser is required, the base of the rack assembly, with a single hopper mounted in it may be utilized.

The hoppers of the present invention are similar, at least in part, to the structure disclosed in the patent to George E. Coursey, for Container with Handle Stacking Means, No. 2,641,383, issued on June 9, 1953. The containers of the patent are intended to be erected directly one upon another in horizontal tiers when in use, and to be nested compactly together when in storage. For supporting the containers in tiers, each container includes a pair of pivoted bails at opposite ends which engage and support the bottom of the container above. When pivoted to a second position, the bails reside between the nested containers and prevent them from jamming together.

According to the present invention, a detachable cover, comprising a lid and spout, is secured in position upon the open face of the container to convert it to a gravity feed hopper. The pivoted bails in the present instance serve two purposes: first, they are used to attach the cover to the hopper; secondly, they provide the pivot bearings which interfit the notches of the base and holders to support the hopper in inclined position.

The present sectional rack, combined with the lid and spout structure, thus takes advantage of the desirable features of the patented container to provide a multiple dispenser which occupies the same or slightly less floor space, but which provides improved segregation of the batches of parts and more convenient access to them. Preferably, the base of the rack assembly is provided with two sets of notches, one set along its upper portion and the second along its lower portion. These are located in positions corresponding to the pivoted ends of the bails which project outwardly from the side walls of the hopper. When cradled in the base, whether used as a single unit or otherwise, the hopper within the base is stabilized at top and bottom by the bail pivot bearings.

Other features and advantages of the invention are disclosed in the detailed description in conjunction with the drawings.

General arrangement Referring to Figure l which shows the structure utilized as an individual dispenser of parts, the hopper, indicated generally at 10, is cradled in an inclined position in the base 11 and feeds the parts by gravity to an open spout 12 projecting from the lower portion of the hopper. As the parts are dipped out of the open spout, additional parts flow by gravity from the hopper to maintain a constant mass of parts in the spout. The inclination of the hopper is substantially greater than the angle of repose of the parts, and the lower portion of the hopper includes an outlet leading to the spout which allows the parts to flow downwardly and forwardly from the hopper.

As shown in Figure 2, one or more hoppers may be suspended in tiers from sectional racks or holders 13 which are interfitted telescopically one upon another and upon the base. As described later in detail, the base. sectional holders and hoppers preferably are fabricated from sheet metal of welded construction. When assembled in multiples (Figures 2 and 8) the hoppers are each suspended by their upper ends from the sectional holders, with the lower portion of each superimposed hopper overhanging the upper portion of the hopper below it. The upper end of each hopper is pivotally connected as at 14 to the upper edge of its particular holder and the hopper, whether loaded or not, swings by gravity against its lower companion hopper. Thus in the multiple hopper assembly of Figures 2 and 8, the weight load of each suspended hopper is transmitted by the pivot bearings to the holders and base, while the lower portion of each hopper is stabilized by the one below it. In the multiple assembly, the several spouts 12 are located one above the other at substantial spacing to allow the workers to reach into them conveniently for the desired parts.

Each hopper is provided with a detachable cover or lid 15 including the spout 12, the lid having an opening 16 communicating with the spout, such that the parts within the hopper are confined by the lid and flow by gravity down the inclined hopper to the open spout. The lid 15 of each hopper is detachably secured to the hopper by means described later and the hoppers are conveniently dismounted from the rack assembly when emptly. For refilling, the lid is removed from the dismounted hopper, a fresh batch of parts is placed in it and the lid structure is snapped back in position. The hopper is then hooked upon the rack assembly, causing the parts to flow by gravity into the open spout in available position.

The weight load of the collective hoppers is generally perpendicular to the base 11, such that the assembly is normally in balance upon its support surface. However, when the rack assembly is built up to a substantial height, it is preferable to attach the base permanently to the work bench or other support surface by means of screws. If desired, the rack sections may also be attached to a wall or other perpendicular surface for added stability. Referring to Figure 9, the rack sections have a configuration in cross section which allows them to be attached together in side by side relationship to provide a battery of hoppers of the required selection of parts, as described in detail later.

Base and sectional racks Described in detail, the base 11 shown in Figures 1 and 3 is generally U-shaped in cross section, comprising a rear wall 17 and a pair of side walls 18. The forward edges of the side walls are inclined outwardly from top to bottom and are provided with pairs of notches 20 at the respective upper and lower ends. The notches receive and confine the pivot bearings 14 which project from the opposite sides of the hopper and form a part of of the hopper bails 21 which are described later. Referring to Figure 3, it will be seen that the pivot bearings 14 cradle the hopper at top and bottom in an outwardly inclined position, with the hopper nested between the side walls of the base and with its spout projecting forwardly.

The base is provided with a bottom plate 22 having right angular flanges 23 at opposite ends which seat against the internal surfaces of the side walls, the flanges being attached to the side walls by screws 24. The bottom plate is further provided wtih holes 25 for attaching the base to the work table, as noted earlier.

The holders 13 are generally U-shaped in cross section, as shown in Figure 9, corresponding essentially to the cross section of the base. The rear wall 26 of the holder is joined by side walls 27 which are less wide than the side walls 18 of the base. The forward edges of the holder slope inwardly from top to bottom at. 28, the lower end 30 being of the same width as the upper end 31 of the base. At their lower portions, the sloping edges 28 reside rearwardly of the notches 20 and lead to the rearward edges of the notches. The edges 28 immediately above the notches thus form guide surfaces which aid in inserting the pivot hearings in the open notches.

The upper end 32 of the holder corresponds to the upper end 31 of the base including the open notches 20 at its forward end. Accordingly, the lower end of the hopper above it interfits in the same manner, with the open notches exposed to receive the pivot bearing 14.

It will be noted that notches of the base are delineated by curved forward edges, indicated at 40, which join the edges of the side walls. The rearward edges of the notches are delineated by the vertical edges 41 at top and bottom. The notches of the holders are substantially the same except that the side walls jut forwardly from the notches in the form of square shoulders 42.

Referring to Figure 9, which illustrates the cross section of one of the holders 13, it will be noted that the outer end portions of the side walls 27 are displaced inwardly toward one another to provide the forward clearance, as indicated at 33 when the holders are connected together in side by side relationship. The offset is provided by the angular sections, indicated at 34 intervening between the forward and rearward portions of the side walls. The side walls 18 of the base are provided with a similar angular section 34a which corresponds in cross section to the holders.

Referring to Figure 3, it will be noted that the lower edge of each holder 13 is provided with a nested connector plate 35 which projects downwardly a substantial distance below the lower edge of the holder. The cou nector plate is generally U-shaped in cross section, corresponding to the cross section of the holder, as shown in Figure 9. Since the cross sections of the holders are identical to each other and to the base, the connector plate interfits snugly within the erected sections.

Referring to Figure 3, the connector plate is attached permanently to the lower portion of the holders preferably by spot welding as indicated at 36. The lower portion of the plate is attached by bolts 37 to the side and rear wall of the base 11 as indicated. The holders and base each have holes 38 formed in their upper edges matching similar holes in the connector plate to receive bolts 37. The base and holders are shipped to the user preferably in knock down condition, together with the necessary screws and nuts and are conveniently erected at assembly simply by placing the holders successively upon the base and upon one another and installing the screws.

As viewed from the side, the assembled rack structure provides a series of inwardly sloping edges terminating in the outwardly jutting shoulders 42. The open notches allow the hoppers to be installed simply by placing the grasses pivot bearings against the sloping edges above the notches and then shifting the hopper downwardly to engage the bearings in the notches; they are removed by lifting them upwardly and outwardly out of engagement.

Modified rack assembly The rack assembly disclosed in Figure 8 is substantially identical to that shown in Figures 1 and 2 except that the base 11 is a composite structure comprising a holder 43 of slightly modified construction having a bottom plate 44 attached to it. The bottom plate 44 projects forwardly from the holder to stabilize the assembly as distinguished from the one-piece structure of Figure l. The holder 43, which forms part of the base, is made somewhat longer than the holders 45 above it, the lower portion of holder 43 being flared outwardly as at 46 and attached by the screws 47 to the end flanges 48 of the base plate The outer edges of the holders of Figure 8 are inclined inwardly from top to bottom as described earlier to expose the notches 20. In the modified structure, the side wall portion above the notch is curved as at 51 to guide the pivot bearing 14 into the notch.

The hoppers are suspended in the rack assembly in overhanging relationship similar to the structure of Figure 3. However, the lower end of the lowest hopper rests directly upon the base instead of being supported by the two pivot bearings 14. The modified structure is intended primarily for smaller, lighter hoppers and it is therefore of somewhat simplified construction.

Hopper and lid As explained earlier, the body of the hopper is similar to the container disclosed in the prior patent except for the addition of the lid which adapts the hopper to be mounted in an inclined position in the rack assembly to confine the parts and to feed them to the spout. According to the earlier patent, the containers are stacked directly one upon another resting upon the bails 21, the parts being available in the inclined open ends of the superimposed containers. It will be understood however, that the hoppers need not follow the disclosure of the patent; other hopper structures, having generally similar characteristics, may be utilized with the present rack structure.

Described in detail with reference to Figures 4 to 7, each hopper is generally of rectangular configuration and includes a bottom plate 52, a pair of side walls 53, and a pair of end walls 54, all formed of sheet metal. The end walls 54 are identical and flare outwardly from the bottom plate toward the open top of the hopper. The side walls 53 also flare outwardly from the bottom toward the top but to a lesser extent than the end Walls. The upper edges of the side walls include shoulders 55 along opposite sides, terminating in outwardly spaced flanges 56.

In the present disclosure, the lid 15 fits between the side walls 53 and is thus confined laterally or widthwise (Figure 10). The opposite ends of the lid engage the opposite ends of the hopper, as described later and thus suspend the lid across the open face of the hopper. As best shown in Figure 5, the upper edges of the side walls, including the shoulders 55, are inclined downwardly at opposite end portions of the hopper as indicated at 57.

The opposite ends of the hopper are curled as at 59 to engage the lid and spout as described later. The bails 21, which are formed of rod stock, are generally U- shaped and comprise a cross bar 58 having right angular arms 6% formed at opposite ends. The arms terminate in the pivot bearings 14 which are bent outwardly at approximate right angles to the arms. The pivot ends project outwardly through the flanges 56 at the inclined portion of the flanges to pivot the bails to the hopper.

The bottom plate and end walls of the hopper preferably are fabricated from a single sheet metal blank which is suitably bent to provide the flaps 61 which overlie the side wall-s. The flaps are joined to the side wall prefen ably by spot welding. The bottom of the hopper is provided with notches 62 at opposite ends which are engaged by the bails if the hoppers are stacked directly one upon another as disclosed in the aforesaid patent.

In the present disclosure, the notch 62 at one end of the hopper may be utilized to partially bear the weight load of the loaded hopper. The rack assembly shown in Figures 1 to 3 is intended for relatively large hoppers which bear a considerable weight load when filled with metal parts. If the entire weight load is concentrated upon the pivot bearings 14, there may be a tendency to spring the side walls of the holder. For the large sized hoppers therefore, each holder 13 may be provided with a stirrup 63 which engages the notch as shown in Figure 3.

The stirrup is generally U-shaped, having pivot bearings 64 projecting outwardly from the ends of its arms and having a cross bar 65 engaged in the notch. The pivot bearings project through the side walls of the holder at its lower portion and the outer ends of the pivot bearings may be flattened as at 66 to prevent withdrawal.

The lid structure 15 shown in Figures 4 and 6 is of sheet metal construction, comprising a plate 67 which is bent to provide sloping portions 68 and 70 at its opposite end portions. The plate and its sloping portions correspond. generally to the contour of the top of the hopper. The width of the lid is slightly less than the spacing of the hopper side walls 53 to allow the plate to fit between them. The side edges of the lid proper are provided on opposite sides with flanges 69 for stiffening purposes. As explained later, the sloping portion 70 is slightly yieldable and includes an angular catch 71 along its outer edge which interfits the curled edge 59 along one end of the hopper.

The opposite end of the lid includes the spout support frame, consisting of a plate 72 which, as viewed in Figure 4, projects forwardly from the sloping portion 68 in a plane corresponding to the end portion of the hopper which it interfits. Plate 72 is welded to the lid and includes the outlet opening 16. The spout preferably is of welded sheet metal construction and includes a bottom 73, a front wall 74 and a pair of end walls 75. The end walls include flaps 76 and 77 along their opposite edges which are attached by spot welding to the support frame 72 and to the front wall of the spout. The edge portion of plate 72 is welded to the inclined end portion of the lid as indicated at 7-8.

At the juncture of the bottom 73 and plate 72, the spout is provided with a hook 80 in the form of aright angular flange which engages the curl 59 when the lid is placed in position upon the hopper. As best shown in Figure 3, the lid is locked in position upon the hopper by engagement of the flange 80 with the curl 59 at one end, the opposite end of the lid being locked in position by engagement of catch 71 with the curl 59.

It will be noted in Figure 5 that the hopper is symmetrical, the ends being identical so that the lid structure may be applied in either position. Upon being placed upon the hopper, the lid is slipped beneath one of the bails with the hook 80 engaging the curl 59 at the lower end of the hopper. The free end of the lid, which includes the yieldable portion 76 and catch 71, is now forced against the upper end of the hopper, causing the catch to spring over the curl 59 in detent fashion to latch the free end of the lid. This secures the lid under tension between the curls 59 at opposite ends.

A keeper 81, in the form of a right angular flange, engages the bail as the lid is slipped in position on the hopper. The keeper locks the bail out of the way so as not to interfere with the spout opening. The bail at the opposite end is utilized to suspend the hopper and its cross bar preferably is swung to an inoperative position (Figure 3).

The spout structure is firmly attached to the end of the hopper by engagement of the hook 80 with the curl at the 7 spout end of the hopper as shown in Figure 3. The filled hopper is then installed in its inclined position in the rack assembly as explained earlier. It will be noted that the inclined ends of the hoppers assume a substantially level position when placed in the rack assembly, in plane with the bottom of the spout.

From the foregoing description, it will be apparent that the structures shown in Figures 3 and 8 both provide the advantages of conveniently erected sectional receptacles which may be utilized selectively as an individual unit or in the desired number of multiples. In both structures, the batches of parts are replenished conveniently and quickly as the hoppers become exhausted.
