US3782599A — Device for feeding glue from a glue container to …

Claim 1

Independent Claim 179 words

In a device for dispensing liquid glue, a liquid glue supply container having a removable top cover and a bottom outlet; a liquid glue dispensing head; conduit means connecting said dispensing head with said bottom outlet of the container; the improvement comprising said container being partly filled with a predetermined amount of liquid which is inert to and immiscible with the glue, and which has a specific weight less than that of the liquid glue so that it forms a protective layer on the top surface of any liquid glue in the container, thereby continuously preventing contact between air and said liquid glue in the container; and float-rod means carried by said top cover with the float means in said protective layer of liquid provided with indicator rod means extending upwardly through an opening in said top cover of the container and provided on its projecting portion through the top cover with indicator means to show the depth location of said float means within the container and thereby the surface level of the liquid glue supply in the container.

Claim 2

Dependent Claim 179 words

In a device for dispensing liquid glue, a liquid glue supply container having a removable top cover and a bottom outlet; a liquid glue dispensing head; conduit means connecting said dispensing head with said bottom outlet of the container; the improvement comprising said container being partly filled with a predetermined amount of liquid which is inert to and immiscible with the glue, and which has a specific weight less than that of the liquid glue so that it forms a protective layer on the top surface of any liquid glue in the container, thereby continuously preventing contact between air and said liquid glue in the container; and float-rod means carried by said top cover with the float means in said protective layer of liquid provided with indicator rod means extending upwardly through an opening in said top cover of the container and provided on its projecting portion through the top cover with indicator means to show the depth location of said float means within the container and thereby the surface level of the liquid glue supply in the container.

Claim 3

Dependent Claim 30 words

The device according to claim 1, in which said liquid forming said cover layer is a mineral oil which adheres more firmly to the container wall than does the glue.

Claim 4

Dependent Claim 116 words

The device according to claim 1, in which said removable top cover of the container is provided on its underside with a downwardly converging collar which when said top cover is in a closure position on the container the collar projects into the container, while when the top cover is removed from the container and placed on a substantially horizontal support surface with said float means within said collar and with the peripheral edge of the collar and the top end of said rod means in contact with said support surface, said collar together with the adjacent portion of said top cover forms a drip pan for any traces of liquid remaining on the float means.

Claim 5

Dependent Claim 173 words

A float and top cover assembly for a liquid container, comprising a removable cover member provided on its underside with a downwardly projecting annular collar; an indicator rod extending slidably through an opening in said cover member and having an annular stop member on its top end portion and a plurality of depth indicator markings beneath said stop member; and a float secured to the lower end of said indicator rod and being of less transverse dimension than said annular collar, the diameter of said cover member being greater than the diameter of the stop member, so that when said assembly is removed from the container and placed upon a substantially horizontal support surface and said float retracted to within the confines of said collar and wIth the outer edge of said cover member and the stop member on the top end of said indicator rod in contact with the support surface, said collar together with adjacent portions of the cover member forms a drip pan for any liquid remaining on said float.

Claim 6

Dependent Claim 173 words

A float and top cover assembly for a liquid container, comprising a removable cover member provided on its underside with a downwardly projecting annular collar; an indicator rod extending slidably through an opening in said cover member and having an annular stop member on its top end portion and a plurality of depth indicator markings beneath said stop member; and a float secured to the lower end of said indicator rod and being of less transverse dimension than said annular collar, the diameter of said cover member being greater than the diameter of the stop member, so that when said assembly is removed from the container and placed upon a substantially horizontal support surface and said float retracted to within the confines of said collar and wIth the outer edge of said cover member and the stop member on the top end of said indicator rod in contact with the support surface, said collar together with adjacent portions of the cover member forms a drip pan for any liquid remaining on said float.

Claim 7

Dependent Claim 18 words

The assembly according to claim 4, in which said annular collar is convergent downwardly from said cover member.
