METALLIC STRUCTURE FOR THE TOPS OF RECEPTACLES.
Specification of Letters Patent.
Patented Apr. 11, 1916.
Application filed July 8, 1914. Serial No. 849,734.
To all whom it may concern Be it known that I, MILTON O. ADAMS, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Metallic Structures for the Tops of Receptacles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to metallic structures, and particularly to metallic coverings or tops for receptacles, and aims to provide a one-piece structure adapted to serve as such a covering and also formed with an upright marginal molding so constructed as to embrace and be retained by ?o the upper edges of the walls of thereceptacle.
It is also one of the objects of the invention to arrange one of the marginal molds where the structure is employed in connection with special forms of receptacles rethe invention will now be described with reference to one form of embodiment thereof which has been found to be thoroughly practical and eflicient, as illustrated in the accompanying drawings, after which those features deemed to be novel will be severally specified in the appended claims.
In the drawings-Figure 1 is a perspective view of a receptacle provided with a top or cover embodying the present improvements; Fig. 2 is a fragmentary side elevation of the same; Fig. 3 is a central vertical section through the receptacle and cover, extending from front to rear, the receptacle being partially broken away; Fig.
0 4 is a plan view of the blank from which the top or cover is molded; Fig. 5 is a bottom plan view of the top or cover after the same is molded; and Fig. 6 is a fragmentary perspective View of the removable cap or lid used in connection with the cover opening.
Referring to the drawings, the top or extension, when desired.
cover member proper is constructed from a continuous sheet of metal 2, as illustrated in Fig. 4, which sheet is stamped by suitable cutting mechanism for cutting out the blank indicated by the full lines in said figure. This results in a blank having the main or rim portion 4; the central opening 6, the corners of which are slit, as at 8; the marginal portions 10 with the scalloped ends 12; and the marginal extension 14 provided with the rivet holes 16 and the bracket-forming portions 18 (in case it is desired to provide integral bracket portions in this manner). By suitable die action, the metal between the slits 8 is deflected downward at right angles to the rim portion,
along the dotted lines 20 in Fig. 4, thereby forming the flanges 22, while simultaneously the marginal portions 10 and the extension 14 are deflected in the opposite direction along the dotted lines 24; and in the same operation lines of corrugations 26 are formed parallel to the marginal portions 10 between the same and the opening 6. By means of suitable tools, the marginal portions are then rolled outward, downward and inward to form upwardly projecting beads around the front and sides of the cover, as illustrated inFigs. l to 3, the rear ends of the side beads being slightly flattened, as shown at 28, and the ends at the front corner edges 12 fitting exactly to gether and forming, when soldered-or otherwise secured, a miter joint at each of said corners. In the case of the extension 14, the same is folded along the several dotted lines 30 to form an upright wall across the rear of the cover, having flat front and rear clamping faces to permit the mountingof suitable attachments upon the The extension 14 is hollow or tubular, and designed to be fitted with a wooden filler 32see Fig. 3. The rear edge of the metal comprising the extension 14 is downturned to extend parallel with thefront wall of the extension and slightly spaced therefrom; and similarly, the outer margins of the metal forming the beads 10 are slightly spaced from the inner walls of said beads, so that there is thus provided a downwardly opening channel 34 entirely around the rim portion 4 for the purpose of fitting the cover upon the upper edges of the walls 36 of the receptacle to which the coveris to be applied. When mounted in this manner, the cover may be secured by soldering the same to the receptacle walls, or by means of rivets 38, as illustrated in the case of the extension 14, passing through the openings 16.
Suitable angle brackets l0 may be provided for bracing the extension 14 from the upper face of the rim at, but it is preferred to employ the integral bracket-forming portions 18 already referred to, which are folded forward and their free ends bent inward and secured to the rim portion l by additional rivets 38. These portions 18 thus serve not only as brackets but also as a means for closing up the ends of the tubular extension 14 and preserving the neat out- Ward appearance of the latter. Prior to fitting the top or cover upon the receptacle, a reinforcing band 42 is fitted around the flanges 22, and, by means of a suitable die mechanism, the flanges are deflected and clamped about said band, and then secured thereto by rivets 4:4: passing through the ends of the band.
For closing the opening 6, a removable cap or lid 46 is provided, which is also made from a single piece of sheet metal, being of angular contour corresponding to that of the opening, and doubled back upon itself at its borders to form shoulders 48 adapted to rest upon the edges of said opening (see Fig. From the inner margins of the doubled portions or shoulders are provided downwardly projecting flanges 50 for fitting within the opening 6, the bottom edges of which flanges are folded back upon themselves. At each corner, moreover, one of the flanges 50 projects sufliciently to overlap the end of the adjacent flange, and the lower edge of the latter is folded over this overlapping end, as clearly shown in Fig. 6, thereby affording a firmly braced and substantial construction; it being noted that the end portion of said projecting flange is reduced somewhat in width to permit the folding over of the adjacent flange.
From the foregoing it will be apparent that an extremely simple and efiicient construction has been devised for fulfilling the objects of the invention. The mode of formation which makes use of the angular, rolled and folded construction, renders the device most rigid and durable, and, each of the parts being of one piece of sheet metal and the process of constructing the same being of but few steps or operations, the cost of producing the structure is quite low. Moreover, the integral construction has another important advantage in that the number of joints and crevices or seams is reduced to a minimum, which is a very desirable feature, especially where it is sought to provide as sanitary structures as possible. This is particularly true in the case of washing apparatus, for which the structure described is quite favorably adapted, the rolls or beads 10 and the extension 14 forming a retaining wall about the top to guard against the waste or dripping of water out over the sides of the receptacle, and the extension let also serving as a firm and substantial support for the attachment of the wringer commonly applied to the washing machine; but while the use illustrated has been with particular reference to this adaptation of the improvements, the invention is also well adapted to other types of receptacles, such as to the covers of fire-proof grain bins, waste or trash receptacles, well copes, etc.
The foregoing represents what is now conceived to be the preferred mode of practising the invention, but the right is reserved to such changes or modifications as may fairly fall within the scope of the appended claims.
1. A metallic structure for the tops of receptacles comprising a single sheet of metal having a central opening provided with marginal tapered flanges, and a reinforcing member of the size of the said opening, said flanges being folded about said reinforcing member to retain the latter in position and exposing portions of the same be tween the ends of said flanges.
2. A metallic structure for the tops of receptacles comprising a single sheet of metal having one of its marginal portions molded to form an upright hollow extension with flat attachment-clamping surfaces, the remaining marginal portions of said metal sheet being molded to form an upwardly projecting bead providing a channel for embracing the upper edges of the receptacle walls.
3. A metallic structure for the tops of receptacles comprising a single sheet of metal of substantially rectangular form having a central opening and marginal edges molded to form an upright wringer-attaching portion at the rear and upwardly projecting beads at the front and sides of the structure, said marginal beads being formed with downwardly facing channels for embracing the upper edges of the receptacle walls and said beads being secured together in miter-joint relation at the front corners of the receptacle.
4. A metallic structure for the tops of receptacles comprising a single sheet of metal having one of its marginal portions molded to form an upright hollow extension with flat attachment-clamping surfaces, the lOWer portion of said extension and the remaining marginal portions of said metal sheet being formed to provide a downwardly opening channel for embracing the upper edges of the receptacle walls.
