COVER-FASTENING FOR PACKlNG-RECEPTACLES.

SPECIFICATION forming part of Letters Patent No. 272,873, dated February 27, 1883.

Application filed September 14, 1882.

To all whom it may concern Be it known that I, SPENCER L. FRASER, a

- down the removable covers of packing pails,

tubs, barrels, casks, boxes, and other similar receptacles. This class ofreceptacles,as heretofore constructechhave either been devoid of a cover, having merely heads, to remove which it is necessary to start the hoops, thereby causing a leakage of the liquid contents, or their covers have been fastened by devices too complicated and expensive to be economically applied to receptacles for packing goods to be placed upon the market. a

A further object of my invention is to provide a cover-fastening with a cheap, effective, and easily-applied lock, in order to prevent pill'ering of the contents of the receptacle.

The accompanying drawings illustrate my invention as applied to the cover of a packing pail or tub.

Figure 1 is a plan of the pail, showing the cover. fastened down. Fig. 3 is a similar plan; but-the cover is here shown as unfastened. Fig. 3 is a vertical mid-section cut in the plane of the line 3 3 in Fig. 1, and showing the cover fastened down. Fig. 4 is a vertical mid-section of the pail cut in the plane of the line as in Fig. 1, and showing the cover and its fastenings in side elevation. Fig. 5 is an enlarged plan of part of the cover-fastening. Fig. 6 is a longitudinal section of Fig. 5 on the line 6 6- therein. Fig. 7is a transverse section of Fig. 5 on the line 7 7 therein.. Fig. 8 is a plan of a modification, and Fig. 9 is a vertical section thereof answering to Fig. 3.

A designates the pail as a whole, and B its removable cover. The pail is hooped in the usual manner, and has the usual bottom head, 0; and, in addition thereto, it has an annular top or upper head, D, the central opening in which serves for unpacking and packing the pail. The cover B fits into this opening, and has a flange, 1), Figs. 3 and 4, which, when it is in place, rests on the head D. Beneath this (No model.)

flange is placed a rubber or other elastic packing-ring, a, which, when compressed in the tightjoint between the cover and head.

On opposite sides of the pail, close to its staves, and on top of its upper head, are fixed two cleats, E E, or other'provisions, having overhanging shoulders. These shoulders are shown as formed by mortising out the under side of each cleat, as indicated in dotted lines in Figs. 1 and 2, and as shown in section in Fig. 3. I shall refer to these overhanging shoulders by the letters 6 0, it being understood that it isimmaterial how they are formed,

cient strength to withstand the upward pressure necessary to securely fasten down the cover. On the top of the cover B are two bolts, F F, arranged in line with each other and extending diametrically of the cover. These bolts are arranged to slide longitudinally for a short distance, being connected to the cover in any suitable way. I have shown them as having slotsff, through which pass screws 0 c,driven into the cover B, which is a cheap and simple connection. Between the adjacent ends of the bolts F F a wedge, G, is arranged in a direction at right angles to the axis of the bolts.

On each side of the wedge, and projecting therefrom in a horizontal plane, is a plate or wing, H, which, it the wedge is made of metal, may be cast inone piece with it; or they maybe overhanging parts of a separate plate or thin board fastened to the top of the wedge. These wings H H are formed with two slots, h h, ex tending parallel to the two inclined sides of the wedge, and each slot engaging a screw or other projection, d, on the bolt F. When the wedge- G is driven in, its inclined sides thrust apart the bolts F F, as shown in Fig. 1. When the Wedge isdriven back by striking its narrow end, the sides of the slots h h act on the projections 61 (Z and cause the bolts F F to move toward each other, as shown in Fig.2. Hence to apply the cover after having packed the pail, the wedge being driven back and the bolts retracted, the cover is put. in place, as shown in Fig. 2, with the bolt ends opposite the snoulders e e, and the wedge Gris driven home tightneath the shoulders e 0. Either the shoulders act of fastening down the cover, forms a waterso that they are fixed to the pail and have suffi- 1y, thereby projecting the ends of the bolts be- 'or the tops of the bolt ends are beveled or inclined, or both are so formed, as shown in Fig. 3, in order that as the bolts are driven out they will act as wedges to force the. cover down firmly on its seat and make a tightjoint.

To open the pail the wedge is driven back, which retracts the bolts and permits the cover to be lifted off. Thus a few blows ot' a mallet snffice either to close or open the pail.

The wedge Gr may be kept in place on the cover by means 6f screws 61 (1, whose heads overhang the slots h h, and thereby prev'ent theliftingor verticaldisplacementofthewedge; but this is not necessary in the construction shown, which is mostclearly illustrated in Figs. 5, 6, and 7. The wedge G has a longitudinal slot,g, formed in it,extending nearly to its ends. In this slot is placed a cleat or bridge, I, which is screwed down to the cover 13. This bridge is formed of a top piece, t', and two legs,j j. The former stands above the top surface of the wedge, and thelatter rest on the cover B and have shoulders]; 70, which overhang the top of the wedge and serve to keep the wedge from lifting.

On one side of the top pie e, t, is a downwardly-projecting flange, m, formed with halfronnd notches, and on the wedge, just beneath this flange, is another upwardly-projecting flange, n, having also half-round notches ot' the same size, but differently spaced, after the manner of a Vernier. As the wedge is driven the flange m moves over the flange a, and one after another of the upper and lower notches coincide to form complete holes. When the wedge is driven tight a pin or key, 0, is driven into the hole formed by the two coinciding notches, thereby preventing the wedge from becoming loose or from being driven back until the pin has been removed. To prevent pilfering, a padlock or seal might be passed through this hole.

It will be obvious that this device might be modified in many ways without essentially changing it. By its means a very simple and cheap lock is formed.

To keep the wedge from becoming loose, a series of holes might be made tranversely through its small end and a pin driven into either of these holes, with its end projecting.

My invention is applicable to kegs, casks, and barrels, as well as to pails, it being only necessary to form a large opening in the upper head and provide the cover and fastening which I have described. It may also be applied to tubs and boxes. In Figs. 8 and 9 I have shown it as applied to a tub, such as a butter-tub. Thereisnotophead,D,theflanged cover resting directly on the top of the tub instead. The shonlders e e are form d as holes in two outside staves or projecting strips, E E, which are fastened to the outside of the tub and project above its top. Otherwise this construction is the same as that shown in Figs. 1 to 4.

I am aware of the fastening for boxes shown in the patent of Simpson, No. 222,745, dated December 16, 1879; but this differs from mine in that the fastening bolts and wedge are arranged beneath the cover instead of on top--a construction which necessitates making holes in the receptacle through which to manipulate the wedge, and which is consequently unsuited to the packing of liquids or wet goods, because of the practical impossibility of preventing leakage through said holes. in my receptacle the only opening into the interioris that which is closed by the cover when it is in its place.

I claim as my invention 1. The combination, with pail or other receptacle A and overhanging shoulders e e, fixed thereto above the seat for the cover, of cover B, fitting tightly over said seat, sliding bolts F F, arranged on the top of said cover, and wedge Gr. arranged between the adjacent ends of said bolts, substantially as set forth.

2. The combination, with pail or other receptacle A and shoulders e e, of cover 13, bolts F F, projections 01 d thereon, wedge G, plates H, fixed thereto, and slots h h in said plates, substantially as set forth.

3. The combination, with cover B, of bolts F F, wedge G, having slot g therein, and cleat or bridge I, having shoulders 7c 7r, substantially as set forth.

4. The combination, with cover B, of bolts F F, wedge G, a series of holes or notches on said wedge, and a series of holes or notches on a fixed part spaced differently, so as to vernier with those on the wedge, whereby when the wedge. is driven a key may be inserted through the coinciding hole or notches, to lock the wedge in place, substantially as set forth.

5. The combination, with cover B, of bolts F F, wedge Gr, slot g therein, cleat or bridge I, notched flange m on said bridge, and notched flange a on said wedge, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
