CHARLES ALIVIY, JR, OF CAMBRIDGE, MASSACHUSETT$ ASSIEGNOR TO DEWEY & ALMY CHEMICAL COMPANY, OF CAMBRIDGE, MASSACI-IUSETTE, A CORPORATION OF IVIASSACHUSETTS.
APPARATUS FOR SPREADING LINING MATERIAL 0N COVERS.
Application filed February 17, 1925.
To all whom it may concern:
Be it known that I, CriAnLns ALMY, Jr., a citizen of the United States of America, and resident of Cambridge, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Apparatus for Spreading Lining. Material on Covers of which the following is a specification.
The invention relates to apparatus for redistributing or uniformly spreading liquid lining material over the sealing area of can tops, covers and the like in order to obtain the most eficient sealing effect when applied to the receptacle.
()bjects of this invention are to provide a new and improved apparatus for distributingand uniformly spreading a liquid material of relatively low viscosity and plasticity over a selected area; to provide an apparatus particularly useful in redistributing liquid lining material over the sealing area of can tops, covers and the like in an even and uniform manner; and to provide an apparatus of the above character having the unique features of construction and arrangement hereinafter described.
"1n the copending applications of Bradley Dewey and Theodore T. Miller Serial Nos. 9,823 and 9,826, filed on even date herewith there is shown and described an apparatus for distributing liquid lining material over can tops and the like. After the lining material is so distributed it is as a rule found to be bunched near the outer edge of the cover, thereby militating against the desired air-tight connection when the covers are ap- 'plied to the can bodies. According to the present invention the lining material is redistributed by means of an air nozzle which directs an air current against the lining material on the covers in such a manner that the material is spread over a larger sealing area to form a regular coating of substantially uniform thickness throughout. Con- 'veniently the covers may be rolled along a track by a suitable conveyor arranged beneath the air nozzle so that as the covers are continuously rolled along the air current automatically functions properly to redistribute the material. Although I show a preferred form of apparatus for distributing or applying the material to covers it is to be understood that other forms may be em- Serial No. 9,821.
ployed and I specifically do not intend to be limited to the particular form shown except as specified in the appended claims.
in the drawings,
Fig. 1 is a side elevation of apparatus for distributing liquid lining material on covers, and for redistributing the material over the sealing area;
Fig. 2 is a section on the line 2-2 0 Fig. 1;
Fig. 3 is a fragmentary section of an air nozzle and cover;
Fig. 4 is a top plan view of a cover with the lining material applied thereto;
Fig. 5 is a section on the line 5-5 of Fig. 4:; and
Fig. 6 is a fragmentary section of an air nozzle modified for can covers having a curled edge.
In the embodiment of the invention illustrated a depositor is of the form shown and described in the above mentioned copending application therefore a brief de scription of this apparatus is deemed suflicient in this instance. A depositor A comprises in general a rotating distributing roll 1 dipping into a bath 2 of liquid lining material. and a smaller or regulating roll 3 spaced :1 suitable distance from the distributing roll and extending substantially parallel thereto. The rolls 1 and 8 are driven through suitable connections from a pulley 1, both rolls being driven in the same direction but the regulating roll 3 being driven in such a manner that the peripheral. velocity thereof is less than that of the distributing roll. As described in the aforesaid application, a track 5 extends substantially parallel to the distributing roll 1 on the side opposite from the regulating roll 3, and the covers X are rolled along the track 5 with the peripheral edges thereof in contact with the surface of the distributing roll so that as the covers are rolled along the lining material flows or is scraped from the surface of the distributing roll to form continuous rings on the covers. For rolling the covers X alon the track 5 a con veyor 13 in the form of an endless cable is employed, the cable extending parallel to and at a proper distance from the distributing roll. The covers X preferably assume inclined positions substantially as indicated in Fig. 2 and lie against the conveyor 13 at flange.
a point between the center and the upper positions of their peripheries thereof so that by driving the cable the covers are continuously rolled along. For driving the cable sheaves 6 and 7 are employed over which the cable passes and a weighted sheave 8 maintains the cable taut, the sheave 6 being suitably connected to be driven from the pulley 4:.
From the depositor A the covers X are propelled by the conveyor B to a track 9 of channel form in order to support the lower periphery of the covers and arranged above the track 9 is a distributor C which is preferably in the form of an elongate tubular nozzle having a slit l0 and a lower portion extending substantially the entire length thereof. by directing a gaseous fluid such as air through the inlet conduit 11 from a suitable source such as a centrifugal blower the liquid lining material on each cover X which has been unevenly distributed circumferentially of the cover (Fig;
3) by the depositer A is spread over the sealmg area of the cover 1n substantlallya uniform manner as indicated in Fig. 5. it will be apparent that owing to the rolling action of the covers X along the track 9,
the air current from the distributor C will impinge against the lining material de posited on the cover throughout its circumferential margin and cause it to flow radially inward until it reaches the inner edge of the seal area or channel and to become uniformly disposed over the area thus covered so that in this manner the effective sealing of the cover is materially increased.
The apparatus above described for positing a liquid lining material on the covers and thereafter distributing lining material uniformly over the sealing area, is intended principally" for use in connection with covers having an upstanding peripheral Under some circumstances it may be desirable to crimp or curl the peripheral flange on the covers prior to the depositing and distributing of the liquid lining material, and in this case the lining material may be deposited on the covers by any suitable means such as by a machine which rapidly rotates the covers under a nozzle which opens momentarily and squirts a measured amount of the material under the curledflange, such machine being at present in use universally. For distributing or spreading the lining material uniformly over the sealing area a distributor C of the form indicated in Fig; 6 may be employed, this distributor having an extension nozzle 12 suitably arranged to direct the fluid deposit under the curled flange, thus effectively increasing the specific sealing area of the cover and rendering the same of uniform distribution and contact with the cover surface.
Although the above describedapparatus tain apparatus which is the best form known to me at the present time, it is to be understood that numerous changes in detallsof construction and arrangement may be effected without departing from the spirit of the invention, especially as defined by the appended claims. 7 It is further to be under.-
stood that I do not limit the invention to the use of any particular kind of sealing compound, but may use any suitable compound adapted for the particular purpos-e, although it may prove necessary that certain minor details of construction and arrangement the changed. 7

An apparatus of the character described comprising in combination a depositor for depositing liquid lining material on covers, a pneumatic distributor for spreading the material more uniformly over the sealing area, and a conveyor for successively moving the covers from the depositor to the distributor. 1 i
