ISIDORE BLOOH, OF PARIS, FRANCE, ASSIGNOR TO EDYVARD MAMELSDORF,

MACHINE FOR ATTACHING GASKETS TO CAN-HEADS.
SPECIFICATION forming part of Letters Patent No. 579,104, dated March 16, 1897. Application filed October 10, 1896. erial No. 608,4l- (No model.) Patented inI'rance 00t0lJe1'25, 1895, No. 248,488.
To aZZ whom it may concern.-
Be it known that I, IsIDORE BLOCH, a citizen of France, residing at Paris, France, have invented certain new and useful Improvem cuts in Machines for Attaching Gaskets to Can- Heads, (for which I have obtained Letters Patent in France, No. 248,488, dated October 25, 1895,) of which the following is a specification.
In hermetically sealing preservin g-cans two systems are employed-one by soldering the head on the can-body and the other by seaming. The latter system requires for securing a hermetic sealing of the can or box the employment of a rubber ring or gasket between the head or body of the can or box. This means of sealing the joint is objectionable for the reason that by the action of the heat it is liable to become loose. It is further objectionable as it cannot be applied to cans in which oil, fats, preserves, &c., are contained, as these substances gradually dissolve the rubber ring or gasket.
My invention relates to new machines for attaching gaskets to can-heads, whereby is produced a novel joint which fully complies with all the requirements and which is not impaired by the action of oil, saccharine liquids, or heat. The joint produced is made a certain thickness, so that it yields or gives in seaming the heads of the cans and supplies a very hermetic closure for the same. WVhile the rubber gasket can only be set or shaped by heat, the cementing of a gasket to the canheads under my invention can be done by means of any suitable glue.
In the accompanying drawings, Figure l is a vertical section of a head of a can or other vessel provided with its gasket. Fig. 2 is a plan view of the head. Fig. 3 is a front elevation of the machine for applying the gaskets to the heads, partly in vertical section at the right-hand side through the axis of the piston. Fig. tlS a side elevation of the machine.
Similar letters of reference indicate corresponding parts.
The oifset circumferential portion 61 of the head cl of a can or like vessel is coated on its under surface with a suitable glue, and said coated part of the head is then covered by a gasket formed of woven fibers of aniiantus,
which is cut and formed into proper shape in any suitable manner.
My improved machine (see Figs. 3 and 4) is mounted on a suitable standard A, made of gooseneck shape, which is provided with bearings for the shaft 0, to which is pivoted a double lever f. The short rear arms f of the double lever f carry a link h, which is pivoted to a lever j, that is applied by a pivot t to a bracket 1', projecting from the base of the standard A. Supported by the standard A is a guide-cylinder g, which is supported by clamping it between the concaved upper end of the standard A and a removable clamp A, which is secured to the standard by means of bolts and nuts I), which pass through ears on the clamping-section and corresponding ears on the standard. By tightening up the nuts the clamping-section A is caused to firmly hold the guidecylinder q against the upper end of the standard A. The double leverf is pivoted near its mid-length to studs V of a vertically-movable hollow plunger 19, which is guided on the fixed guide-cylinder q, while the front ends of the double lever f are connected by a transverse handle 9. By lowering the double lever f the cylindrical hollow plunger 19 is guided on the stationary cylinder g, which latter projects into the opening in a circular yoke r, that is supported by arms 7" on the base of the standard A. The interior diameter of the yoke r is slightly larger than the exterior diameterof the lower end of the guidecylinder q. The lever j en- 8 5 gages by its rounded-off forward end in acorresponding cavityj of a piston K, which is guided in a chamber 7; of a cylinder L, forming part of the base of the standard A, said cylinder having a lateral orifice 7a, through 0 which the lever extends.
For applying the covering-gasket ac to the offset portion cl of the head d, the head, after being coated at its circumference with a suit able liquid glue, is placed on the top of the piston K, which has at its upper end a profile that corresponds to that of the head (I. The packing-ring or gasket is then placed around the lower part of the cylinder q below the hollow plunger 19, said gasket being cut lengthwise of the fibers, so as to form a perfect packing-joint. By lowering the double lever f by means of its handle g the hollow cylindrical plunger 19 is moved downwardly, so that the gasket 00 is passed between the guide-cylinder qand the yoke 0". During this period the piston K and' the head d, supported on the same, are raised so that the glue-coated circumference d of the head is placed in contact with the gasket 00, and the latter is placed around the circumference of the head by the action of the plunger p and piston K. Pressure is exerted on the circumference of the head until the gasket adheres tightly to the same without being able to change its shape.
The gaskets are caused to pass through the space between the yoke and guidecylinder g by placing a number of the same in superposed series around the lower end of the cylinder, so that the pressure exerted on the up per ones by the lowering of the hollow plunger will be imparted to the lower ones, whereby the latter are forced off the cylinder q.
A spring R is suspended in the hollow interior of and from the upper part of the stationary guide-cylinder q and is attached to the studs V, that pass through slots q in the guide-cylinder, so that when the lever is released the movable parts may be returned under the actuation of said spring to their former raised position, thus permitting the head d and its attached gasket to be removed from the piston K. The shapes of the heads can be changed at pleasure by providing some with different profiles, in which case the profiles of the plunger 19, stationary cylinder q, and piston K must be in conformity with the head.
My improved machine is especially adapted for applying gaskets made of amiantus; but
this gasket may, if necessary, be made of other suitable material which can be applied by suitable glue to the circumference of the head.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a machine for attaching a gasket to can-heads, the combination with a standard, a yoke supported from the standard, and a stationary guide-cylinder projecting into the opening in the yoke, of a piston guided below the yoke, a cylindrical hollow plunger guided on the fixed guide-cylinder, and means for operating said piston and said hollow plunger, substantially as set forth.
2. In a machine for attaching gaskets to can-heads, the combination with the supporting-standard, a yoke supported at the lower part of the standard, and astationary guidecylinder supported from the upper part of the standard, of a piston guided in the lower part of the standard below said yoke, a hol low cylindrical plunger guided 011 said guidecylinder, a han d-lever f ulcrumed to the standard and pivotally connected with said plunger, and connections between the hand-lever and piston, whereby the piston and the plunger are simultaneously operated, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
ISIDORE BLOCH.
