UNITED STATE-IS. omce i asisez HANDLE ASSEMBLY of New York Application December 16, 1947, Serial No. 792,079

3 Claims. 1 The present invention relates to handles and is particularly concerned with improvements in facilities enabling firm, reliable and safe attachinkent of glass handles to kitchen utensils and the 1 e. ployed in combination with medium sized glass utensils wherein only moderate stresses are encountered in lifting such utensils when filled.

The object of the present inventionis a glass handle assembly particularly suitable for use with a metal utensil.

In the accompanying drawing the invention has been illustrated, by way of example, as applied to a cast metal sauce pan. It is equally applicable to other types of metal utensils in which the handle socket may berformed as an integral part of the utensil or may constitute a separate element rigidly attached to the utensil by welding, riveting, clamping, or similar means.

Fig. 1 is a plan view partly in section showing a fragment of a sauce pan with a glass handle attached thereto in a manner in accordance with the invention.

Fig. 2 is a sectional elevation taken on line 2--2 of Fig. 1.

Fig. 3 is an exploded perspective view of the bolt and cushioning sleeve of the assembly.

The handle employed has the usual hand-grip portion H enlarged near the vessel (and to form a shoulder l2 for abutment against the edges of walls l3-I6 forming a handle socket iii of a cross-sectional configuration and size to just easily receive the end I! of the handle. ing transversely through socket walls It and I4 are aligned apertures for receipt of a bolt l8 having an eccentric portion 20 which passes through a sleeve 2| occupying suitably provided grooves or

notches

22 and 23 in the bottom of handle portion l1 and in the upper surface of socket wall l6 respectively. By turning the bolt IS in a counter clockwise direction the eccentric portion 20 is moved toward the vessel, drawing the handle inward until the shoulder 12 thereof tightly engages the edges of walls l3-l6. A lock nut 25 is then threaded onto bolt I8 tightly against the socket wall l3 to hold the bolt in its handle tightening position.

The handle II, when made of glass, must be protected against abrasion and point loading. The sleeve 2|, preferably composed of soft metal such as copper or the like, affords this protection since it readily conforms to irregularities in the glass surface engagedby it and serves as a bushing in which the eccentric portion '20 of bolt I8 Glass handles have been successfully em the bolt and glass in the handle tightening operation. When the vessel assembly is subjected to heat, expansion of the parts occurs thereby increasing the pressure between the bolt and the glass. At such time the sleeve functions as a cushion to prevent destructive point loading. Obviously, if the handle material is composed of non-brittle material such as wood or metal, use of the sleeve 2! may be dispensed with.

Although applicant has disclosed but one method and/or means for causing the bolt [8 to bear against the glass in a direction to hold it tightly in its socket, other facilities for doing this will occur to those skilled in the art and are believed to be within the bounds of applicants invention as claimed. 7 Y

What is claimed is:

1. In a glass handle and metal vessel assembly, a socket latterly projecting from the vessel with its free end having an opening therein for receipt of a handle, said socket having apertures passing transversely therethrough, a handle hav- 1 ing a portion occupying said socket and having a Passgroove therein in alignment with said apertures I and having a shoulder portion for abutment against that portion of the socket bordering its opening, means comprising a bolt having an intermediate circular portion occupying said groove and having circular end portions eccentric with respect to said intermediate circular portion, and occupying said apertures so that the bolt can be turned to bring said intermediate circular portion to bear against the surfaces of said groove opposite the shoulder portion to tightly draw the latter portion against that portion of the socket bordering its opening, and means for holding said bolt in the position to which it has been turned.

2. A structure such as defined by claim 1 wherein a cushion is arranged between the bolt and a wall of said groove.

3. A glass handle having a portion adapted to occupy a metal utensil handle socket opening, said portion having a groove therein adapted for alignment with apertures through the socket and having a shoulder for abutment againsta handlebordering portion of the socket, a bolt having an intermediate circular portion occupying said groove and having circular end portions eccentric with respect to said intermediate portion adapted to occupy the socket apertures so that it can be turned to bring said intermediate circular portion to bear against the surfaces of said groove opposite the shoulder to tightly draw can turn, thereby preventing abrasion between 58 the latter against the handle-bordering portion 3 01' the socket, and means for holding said bolt in Number its turned position. 1 09'L185 DEO R.
