CONTAINER WITH REMOVABLE LOCKING COVER.

Application filed January 8, 1919. Serial No. 270,185.

To all whom it 'may concern Be it known that we, GOT'IHILF H. SoHwAnz, of the city of Newark, county of Essex, State of New Jersey, and MAX VINT- sononn, of Ridgewood, county of Bergen. State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in a. Container-with Removable Locking Cover, of which the following is a specification.

The objects ofour invention are to provide a container, preferably of metal, of can, barrel, or drum form, of simple, cheap and eflicient construction, of long life, not deteriorated by the inclusion of oxidizing or corroding chemicals, such as strong acids, or alkalies; and also to provide such container, and other containers of like character, with a. removable cover or closure, of a new and improved form, having a lockingmechanism, also of a new, improved, simple, cheap and durable form of construction, of easy operation, by the use of which the cover may be instantly wholly removed from the container when the locking mechanism. is thrown to the unlocking and releasing position; and as quickly returned to place and locked in the closed position, so as to render the container air and gas-tight,

and other and further desirable capabilities and objects will be more fully hereinafter set forth in the description of our said container, its mode of operation and the method of forming the same.

Said invention is fully shown, described and claimed, in the following specification, of which the accompanying drawings form apart, wherein similar letters or numerals of reference designate similar parts wherever found throughout the several views;

4, as applied to a container having an inner non-oxidizable protecting lining upon the main shell, and also on the bottom-piece,covering the same and-its outwardly extending flange, with the ends of such flange lining, and of the main shell lining extending thereover into the joint cavity of the securingrin ld eferring to the drawings The reference letter A designates the main-body portion or shell of our improved container, which is formed of any suitable material that can be formed into any desired shape, size or contour, but which in the preferred form shown is of cylindrical form and! usually of about the size and dimension of the ordinary shipping drum or barrel. In such case the main body, or cylinder shell, is formed in any suitable manner, of any suitable metal (usually sheet steel) of thickness suitable to withstand the rough usage to which containers are usually subected during freightin'g, and such cylinder is closed at the bottom by an inwardly dished bottom-piece B, the bottom annular peripheral flanged edge-portion 11 of which, when forced into place in the bottom portion of A fits tightly in an outwardly extended, enlarged bottom annular recess 12, formed by rolling or swaging or other suitable manner in the extreme bottom end portion of the shell-edge; as hereinafter more fully described.

In cases where the container is to be used for the reception of acidulous or alkaline materials, corrosive of steel or other metals, out of which the main body portion thereof is formed, an inner wall or lining, preferably and usually of lead, indicated by 14: is provided, and while this may be secured to the main body portion A, and bottomv B in any desired manner, such lining is usually inserted in the cylinder A, inthe form of a cylinden of just such size as to be easily inserted therein, and then in any desired suitable means, swaged, rolled, or otherwise forced, into close contact throughout its entire surface, with the interior of the main body or shell A, and further secured to the shell by electric spot or line welding, or in any other suitable manner.

The bottom-ring C is first formedof any suitable metal, usually soft steel, in the form of a seamless integral ring having the upper inwardly extending annular securing mainbody portion 15 merging gradually (as indicated at 16, Figs. 3, 4 and 9 to 12 inclusive) into the lower thinner bottom securing portion 13. i

In carrying out the improved method and process of forming containers herein described and claimed, slight changes and modificatlons in the various steps of such process may be made without departing from the scope of our invention, and we will first describe the same, as used in forming unlined containers, as the process is in its main essentials almost the same.

The main body portion A having been formed, and preferably but not necessarily swaged annularly outward at the bottom, to fit somewhat loosely into the annular lower portion 13 of the bottonrring C, which is forced down over A from the top, into the position shown in Fig. 9, and the lower portion of A from the top 15 of the ring C to the bottom of A, rolled or swaged outward, in any desired manner, by any suitable tools .or machinery, so as to contact lightly with the inner annular face of such ring, from the top. 15 to the bottom line of the main body portion A.

The bottom B, having been in any desired manner, cast, forged, struck up, or spun into the dished form shown, so as to fit tightly into the outwardly and large bottom portion of the main body-portion A, is forced tightly into position therein, with the dished face outward (Figs. 9,, 10, etc) and if in any manner loose, is more tightly fitted in place by the swaging or rolling outward of the flange 20 thereof, in any suitable manner, and by any suitable means or mechanism, or fitted thereto in any other suitable way.

After this, by any suitable tools, means or mechanism, the lower, thinner annular se curing portion 13 of the bottom-ring C is first swaged over the annular bottom edges of A and B, and then swaged, rolled or turned upward, inward and outward, so as to tightly enclose, cover and hold in place the lower depending end flanges of A and B, as clearly indicated in F igs. 1, 2, 11 and 12. v

This operation is substantially similar, whether the container is provided with the lead or other non-corrosive lining 14 or not; and in some cases the entire lining 14, covering the interior of the main body portion A and the bottom B may be of a single piece dished inward at the bottom and having an annular bottom-fold 21 as indicated in Fig.

12, or the covering of the bottom-piece B may consist of a. separate piece 11, entirely covering both the central disk, and the downwardly depending annular flange of suchbottom-piece as clearly shown inFigs. 9, 10 and 11.

The linirigll, is turned outward, down- ,ward, and then backward so as to cover the shown, havin the bottom wall-piece 25 and the upper wa -piece 26 downwardly and upwardly, inwardly flared, as shown in Figs. 1,

3, 4 and 8; which chime-ring is rigidly held.

in position upon the top of the main body portion A of the container between the annular securing head 23 and the top securingbead 22 of A swa ed down over the same as clearly indicated in Fig. 8.

It is, of course, understood that by swaging or in any other manner, the bottom downwardly inclined annular securing ring walliece 25, is made to fit so tightly on the main )ody A. that the oint will be air-tight,

and if desired this joint in certaincases may be tilled with solder, or a homogeneous joint made by electric welding.

For closing the container at the top, while not limited thereto, we prefer to use the improved locking cover, closure or top E, of our new and improved form, comprising the main bottom portion 30, and having the annular outer-edged portion extending upward. outward and then slightly downward, in order to form the gasket-groove 32, to receive the annular soft compressible gasketring 33, preferably ,of soft rubber or other suitable like material, such bottom in the lead or other like lined covers, to be used with like containers, having the bottom face of the main bottom portion 30, provided with the covering 14, of the sheet-lead, etc. which covers the same completely as indicated in .Figs. 3, 4 and 8, and is held in place thereon by having the annular peripheral edge-portion 34, rolled into the gasket-ring groove 32, and rolled over the extreme edge at 34. (Fig. 8) the diameter of the cover being such that the same can be lifted easily in and out of the chime-ring D, as clearly indicated in Fig. 4.

Secured to the main bottom-portion 30 of the cover is the face-plate E, struck up into substantially the dished form shown, and secured to the bottom 30, by spot'welding, or

by rivets 35, which extend through 30, but not through the lead-sheet lining 14, and if desired, such lead sheet may also be more securely held to the bottom-piece by electric, spot or other Welding, at suitable points, (not shown) as may be all the like lining whereever used.

Such securing face-plateE' is provided with the upwardly extending outer periph-.

eral flange or wall 36, from which extends outward at substantially a right angle thereto the top-flange 3'7, beneath which is held in position on the cover the annular expansible cover-locking ring F, which is of the substantially truncated wedge-shaped form in cross-section shown in Fig. 8, the top downwardly and outwardly inclined securing face 38, of such ring being of the same length from front to rear, as the coacting inclined lower face of the upper wall-piece 26 of the annular channelled chime-ring D, while the lower reversely inclined securing-face 39 of the locking-ring, extends much farther toward the center (to 40 of Fig. 8) so as to press the edge of the main-body of the cover down uponthe annular top bead 22 of the main-body portion A of the receptacle, so as to force the soft resilient gasket-ring 33 firmly down on such to-bead 22 so as to make an airtight joint between them, when forced outward peripherally into the fully expanded position shown in F igs. 3 and 8.

The annular flange or wall 36 of the cover face-plate E is broken away at one side as shown at 41 (Figs. 1, 2 and 5) at the point where the ring F is divided or cut across so as to'permit the expansion and contraction thereof and through this opening or break 41, extends toward the-cover center, the expanded and contracting mechanism G of such cover-locking ring-:F, which is preferably but not necessarily of our improved variable and adjustable form shown, more fully hereinafter described, which comprises (Figs. 5 and 6) two lugs 42 and 43, each of any suitable shape, size and construction, formed integral with or firmly secured to the inner face of the locking-ring F, one on either side of the slit lying between the two ends 40, thereof. As shown in Figs. 6 and 7, the lug 43, is a double one, being composed of the upper member 43, and the bottom member 43 (Fig. 6), and between them is pivotally secured by a pivot-pin, bolt or member 55,the short end of the bent handlever 47, which is pivotally connected at its elbow to a double centrally horizontally split toggle member or piece 45, by a pivot-bolt 46, while the other end 45 is in like manner pivotally connected with the ring-lug 42 beyond the split between the two ends 40, of the lock-ring by the pivot-bolt 44, this securing together at the split the two ends of the ring F. in such manner that when the handle or actuating long end of the bent lever 47 is thrown to the extreme left,(Figs. 1 and 5) such ring F will be thrown into the extreme expanded, and cover locking position shown, for the reason that the pivot-pin or bolt 55, securing the toggle-member or piece 45 to the elbow of the bent-hand actuated lever 47, will have been forced peripherally outward so far that a straight line (the dotted line in Fig. 5) cutting the centers of the pivot-pins or bolts 44 and 46, will pass inward-of the center of the pivot-pin or bolt 46, so that the resiliency of the expanded ring F, tending to keep the levers in such position, the entire mechanism will be firmly locked therein against any accidental throwing to the central or rightward unlocking position, indicated in Fig. 2. And in order that the hand lever 47 may be used as a handle to lift out and off the cover, when thrown to such releasing position, without danger of being bent, the extreme end thereof vibrates back and forth in the arc of a circle underneath an arcuate guard-piece 49, struck up out of the securing face-plate E so as to be still secured thereto at the peripheral face and ends, and free therefrom at the inner face of the arcuate guard-piece 49 so formed.

It has been discovered by actual use, that in some cases, by reason of a partial rotation of the securing and locking-ring F, especially when being thrown into the fully expanded and cover-locking position, that cut ting, scoring and grinding and wearing action upon the inner face of the chime-ring D, is liable to be caused by contact therewith, often suflicient to give rise after some time to such imperfect closure of the joint between the cover and main-body portion A as to allow of atmospheric or other leakage thereat; and to reduce this to a minimum, and to provide easy and quick means for ouring any such trouble that might possibly arise, we provide a stop pin 50 secured by riveting, or spotwelding, etc. at its bottom end to the main bottom portion 30 of the cover E, and extending upwards therefrom in the slot of the ring F, or at least within the bases of the lugs 42 and 43 thereof, in

such manner as to limit the rotative movement of the ring F, to the very slightest, by abutment against such pin of one of the lugs, or the adjacent ends of the ring.

As broadly described in the last preceding paragraph but one, the lock-ring expanding, locking and releasing mechanism may be non-adjustable like mechanism shown, de

scribed and claimed in our co-pending application Serial No. 223,447, filed March 19, 191.8, entitled Containers, etc., upon which Letters Patent No. 1,314,708, were granted Sept. 2, 1919, but in this, our improved form shown in the drawings, with but slight but important changes in the construction we have rendered such ring-expanding and contracting mechanism easily andquickly adjustable, by which the amount of the expansion of the ring, when the hand lever is thrown to the extreme cover closing and locking position, may be varied within all possible and desirable limits, whether for the purpose of overcoming wear or distortion, fitting in the first instance, or changing the cover from one can to another. As shown in the drawings, in our preferred form of such adjustable ring expanding and cover-locking mechanism, the ring-lug 42 is a single lug, and the toggle-member secured is usually a double or two-piece link, composed of the upper piece or bar 45, and a lower like piece or bar 45 secured at one end to the ring-lug 42 by the pivot-pin, 44, and at the other by a pivot-pin or bolt 46 to the elbow of the bent lever 47. The other ring-lug is a double one, composed of an upper elongated member 43, and a lower member 43,

each formed integral with or secured to the ring F, at that end, and with just space enough between them to permit of the reception and free vibratory movement therein of the short end of the bent hand-lever 47.

As clearly shown in Figs. 6 and 7, formed in and through the upper elongated ringlocked member 43 (Fig. 7 is a cylindrical journal-box or orifice 53, and in the shorter bottom-like member 43' is formed a like journal-box or orifice 54, of smaller diameter than 53, and with its axes coincident with that of 53; and revolubly supported in 53 and 54, by the upper journal 53', and the lower-journal 54 is the adjustable eccentric throw-member 55, formed integral with 53 and 54, and also with the end-throw journal 56, all of which journals and journal-boxes are cylindrical, in cross-section; but the throw-member 55 has its axis on the line d-d, while the axes of 56, 53 and 54 are all coincident and on the line c-0. And it will be seen that by this peculiar and particular arrangement, by rotating such throwmember 55, upon the coincident axes, of 56, 53 and 54' that the amount of movement exerted by the hand-lever 47 may be varied a distance equal to the eccentricity of the axis of 55 lying on the line d-d from that of the line 0-0.

Rigidly secured upon the end throw-journal 56 by means of a set-screw (not shown), or in any other desired manner, is the throw adjusting-sector 60, having adjacent to its periphery the arcuate line of lock- perforations 61, 61 and 61"; and formed in and through the top of the upper elongated lug member 43 of the expandible-ring F, so as to register successively with the perforations 61 to 61, as the sector 60 is swung or vibrated over the same, is a threaded lockscrew perforation or orifice-58, to receive the threaded end of the lock-screw 62 when passed through any one of the sector perforations (51 to 61 inclusive, into the same, according to the extension of the ring-throw or expansion desired, whereby such sector, and the adjusting and locking mechanisms will be firmly locked against any accidental displacement.

As is clearly shown in Figs. 5, 6 and 7, (and incidentally also in Figs. 1 and 2) by this peculiar construction and arrangement, it'will be seen that as the eccentric throwmember 55 lies inthe orifice or journal 55, formed in and through the short end of the lock-lever 47, so as to permit free vibration of such lever thereon, and is held, in such position solely by the lock-screw 62, that when such screw is screwed fully out of 58, such member 55, and sector 60, being lifted bodily upward and. out of the lugs 43 and 43, the throw-lever 47 will be disconnected, and the locking n'iechanism disconnected from the expandible ring.

As shown in such figures, it will also be seen that when the sector 60 is in the medial position, with the lock-screw 62, in the central lock perforation 61, (as shown in Fig. 5) the throw-member 55, will also be in medial position, and that the short, bent end of the handle or throw-lever 47, will also be in like medial central position relative to its pivotal connection with the lock-ring by wa of the lugs 43 and 43.

t will also be seen that when the sector 60 is thrown to the extreme top of Fig. 5, and the lock-screw passed down through the last lock-perforation 61 on the lower side of Fig. 5, into the lock orifice 58, that when 55 is in such position, that the lock-lever 47 will then press against the rear edge of the member 55 on the side nearest to the axial line (Zd thereof, whereby the hand-lever 47, will, when thrown to the ring expanding and looking position shown in Fig. 1, and Fig. 5, exert a thrust of less length upon the ring equivalent to one-half of its eccentricity; and that, per contra, when it is thrown to the left to the opposite extremity, and the lock-screw 62 is passed down into and through the upper lock sector perforation 61", that such thrust upon the lock-ring Wlll be increased in like manner from that exerted at the medial position, also one-half of the eccentricity of the throw-member 55. From which it will be seen that in this V1- bration of the sector, from end to end, the throw and opening movement of the expanding securing-ring or lock-ring may be wldely but minutely varied.

And while as shown in Figs. 1, 2, 5 and 6, the sector has a throw and a per phery of only about one-sixth of a circle, being practically a sextant, and that being so limited, the throw of the member 55,. does notgive the full adjustment of its whole eccentr city, for many purposes such throw is sufficient; but in the modified form of construction, shown in Fig. 13, we have shown a sectorplate of half-circle form, in which the full eccentricity of the throw-member 55 may be used for such purposes of adjustment, in the ositions assumed by it when at the point of t e exertion of the least throwing movement of the lever 47 and the consequent least expansive movement of the lock-ring possible to be made, or vice versa.

It will be seen that by this particular construction of the locking mechanism the expanding and contracting movement of the securing lock-ring may be varied wlthin micrometric dimensions from the extreme eccentricity of the throw-member 55 to the distances between any two of the perforations 61, etc. of the sector; but we do not intend to limit ourselves to this particular form of adjusting mechanism, and consider that any other suitable means or mechanism which will bring about a like micro-metric adjustment of the amount of throw, of the lock-ring will be within the scope of our invention.

In like manner, we do not intend to limit ourselves to the exact construction of any other part of our invention herein disclosed, nor do we exact chronological sequence of the various steps of our improved method of forming the container-bodies and securing the bottoms to the shell thereof herein described.

As an illustration the bottom ring C instead of being made with a depending flange 1?, as shown in Fig. 9, may be initially cast, rolled, or otherwise formed, into the substantially l. shaped form in cross-section, shown as the second step down in Fig. 10, the bottom B then forced into the as at unenlarged bottom end of the shell A, the bottom-ring (l forced on the shell A, and the shell and depending flange of the bottompiece roll or otherwise forced back tightly into the space between the shoulder 16, and the foot of the L 13, of Fig. 10, into the position shown in Figs. 11 and 12, either before, or simultaneously with the turninginward and forcing outward of such flangeportion 13 and other modifications may be made, all without departing from the scope of said invention our new and improved can, container or receptacle herein disclosed, described and claimed, which would suggest themselves to skilled mechanics after read ing the specification the essential principle of which broadly stated, in so far the formation of a receptacle bottom is concerned, consists in producing a can or container comprising a main-body or shell and a bottom-piece formed separate therefrom forced into an annular peripheral enlargement at the bottom of such shell, and a ring of one piece fitting upon the main-body portion of the shell above the enlargement. and turnedv up over and around the bottom and shell inward, and then forced out-- ward so as to enclose the depending annular edges of the bottom-piece and shell in an annular chamber of the bottom-ring, as so completely formed, by the bending into proper shape of such one-piece annular bottom-r1ng.-
