S. ALLrN, a
To-ztZZ till M1712, it 71mg concern; Be it known that 1, ROBERT citizen of the United States, residing at New York, county of'Kings, State of New York,
have invented certain new and-useful Imrovements in Can-(Alrisrires, of which the fol- V owing is a full, clear, and exact description.

having an annular I am aware'that many so-called frictiontop cans have been heretofore proposed and that some of them have gone extensively into use.
In its preferred form it consists inia can and a removable cover. The top has a horizontally posiouter edge and an elastic'vertically-posh tioned slightly-tapering flange portion at the,
inner edge forming a friction-seat Wall which hasan inclined annular shoulder. The cover hasa main horizontal disk-like central portion with a projecting rim and an elastic vertically-positioned slightly-tapering flange portion at its edge forming a friction-seat wall which has an inclined annular shoulder. The parts are so positionedand roportioned that when the cover is pushed own in place the friction-seat walls fit snugly together and the inclined shoulder of the cover snaps under the inclined'shoulder of the top, the clastic or springy quality of the parts tending to draw or force the cover down more firmly in place, the disk portion of the cover being adjacentthe edge of the tOpfiange. I
The drawings illustrate several forms of cans of my invention, and the rights to apply for and obtain patents for the forms not The parts are constructed of sheet metal for instance, tinand require no packing of joints other than the frictioncand locking joints provided by the top and cover.
The figures are all fragmentary sectional views of can bodies, tops, and covers, with the metal much I Figure 1 shows the preferred form which 'isspecifically claimed'i'n this application. In. Fig. 1, 1 is the body, 2 is the top, and3' is the are reserved forheavier than in ordinary.
cover. The top and body may be integral, but are preferably made of separate parts soldered together. The top has a ledge 4,
ring 5, friction-seat wallfi, and shoulder 7..
The'cover has a rim 8, iriction-scat wall 9, upturned edge 1%), and shoulder 11 The shoulder 7 snaps into the groot re between thedisk part 3 0f the cover and the shoulder 11,-
drawing the cover down andrnaking awedge like joint against 3. The edge do may be omitted. -Iii-this form the cover is protected from injury, is held very tightly in place, butmay be readily pried off.
' Fig. 2 shows a form similar to Fig. 1,. but the edge 10 forms a friction-wall engaging the wall 5 of the top ringand affords an additional seat.
In Fig. 3 the slightly-tapering elastic friction-seat wall 13 of the top terminatesin an outwardly-turned inclined shoulder 14,,preferably preceded by the slightly inwardly curved groove 15.- q The friction-seat wall 17 of the cover has a groove 19, forming an inclined shoulder 20, on which the shoulder 14 shape as the cover is pushed down, the edge of the disk part 16 being adjacent the free edge 14 of the top, so as to afford considera ledge 18 is also near the rim 12. This can has a large capacity.
Fig. 4 shows a form similar to Fig. 3 but the groove isat "the bottom of the triotion-seat 13 of the top and forms the inclined shoulder 14. The inclined shoulder 20 snaps under the shoulder 14". This can does not require quite as much accuracy of construction.
In Fig. 5 the friction-seat 24 of the depressed top 23 terminates in a s ring-flange Wit-ban inwardly-projecting inc ined shoulder 25 and an outwardly-turned free edge26.
L lhe friction-seat 28 of the cover has an exterio'r' groove 29, forming the shoulder 30. The inclined spring-shoulder 25 resses down on the inclined shoulder 30 of t 'e cover and e resistance to the expansive force. The
tends to draw the cover into closer contact I with its seat, as well as afi'ording a sharp line of contact. The ledge 22 and rim 27 are close together. The disk part 21 is adjacent theiree edge 26. This can be made cheaply, and the top drains well into the can.
Fig. 6 shows a form similar to Fig. 5 but the inclined shoulder 30 cf the cover sna s into "the grooves 25. in the top ring, andt e shoulder 26 makes another joint'benath the cover-disk 21.
Q l seams In Fig. 7 thefriction-seat wall 33 of the top ring has the shoulder 34. The cover-seat Fig. 8 shows 'a form similar to Fig. but
the shoulder 34 is of less diameter than the friction-seat 33. The Wall 37 has the groove 38 to form the shoulder 39, which sna s under the shoulder 34. This cover may e put on easier than the cover of Fig. 7.
Each form has'its own advantages, either in cost or ase of construction, capacity, efficiency of joint, ease of o ening or case of closing, or durability, W ich makes each formdesirable in particular cases.
What I claim is.
,1'. A friction-top can comprising a body, a sheet m'etal top ring having a wall affording a substantial friction-seat and an annular out- Wardly-turned flanged locking-shoulder, and a removable sheet-metal cover having a wall affording a substantial friction-seat, an exte-v riorly-projecting rim and an annular interior groove, said shoulder being adapted to snap into said groove. for drawing and holding said cover down snugly on its seat.
2. A friction-top can comprising a body, a
sheet-n1etal top ring having a wall affording a substantial seat and an annular lockingshoulder, and a removable sheet-metal cover having a wall affording a friction-seat and an annular shoulder beneath the under side of the top, said top shoulder being adapted to snap over said cover-shoulder and wedgebeheath the top fdr forming two tight joints in addition to the friction seat engagement.
3; friction-top can comprising a body, a sheet-metal top ring having a downwardlyt'urned Wall with an upwardly-turned exten- Sion affording a friction-seat terminating in' an outwardlyturned elastic shoulder, and a removable cover having a friction-seat, an exterior rim and an interior shoulder over Which'said. elastic shoulder is adapted to. snap "when said seats are in engagement.
4. A friction-top can comprising a body, a
yiclding'sheet-metal top ring having a ledge, a wall affording a friction-seat of substantij area and an annular locking-shoulder, and a removable yielding sheet-metal cover having a rim adjacent the ledge of the top ring, a wall affording a friction-seat, and an annular groove into which said shoulder is adapted to sna v I 5 A friction-top can comprising a body, a sheet-metal top. ring having a slightly-tapering friction-seat wall terminating in an annular outwardly-flaring elastic shoulder, and a removable cover having aslightly-tapering friction-seat Wall and a shoulder adapted to be engaged by said top shoulder.
6. A friction-top can-closure comprising a top having a ledge, an upturned elastic friction-seat wall terminating in an outwardlyturned shoulder, and a removable cover having an interior groove for the shoulder, a downturned friction-seat wall and a project D is in place.
7. A can-closure comprising the combination Wih a top member having a ledge, an
annular horizontally-positioned ring and an elastic vertically-positioned slightly-tapering friction-seat wall, with a continuous inclined locking-shoulder, of a cover member having a central disk-like portion, a projecting rim, and an elastic verticallyositioned slightlytapering friction-seat wallwitha continuous inclined locking-shoulder, the arts being so positioned and proportioned that the shoulders interlock and the elastic quality of the parts draws the friction-seat Walls into closer engagement with each other the disk-like central portion of the cover being adjacent the free edge of the top flange when the shoulders are interlocked. I s
8. A friction-top can-closure comprising, a body, a top ring having a ledge and a downwardly-turned flange with an upwardlyturned extens on forming a friction-seat wall and terminating in a locking-shoulder and a removable cover having a projecting rim, a locking-groove for said shoulder and a downwardly-turned flange forming a friction-seat wall adapted to engage the upwardly-turned extension-wall of the top ring, said cover being free from contact with the downturned flange of said top ring.
