HEAT-INSULATOR FOR HANDLED VESSELS.

SPECIFICATION forming part of Letters Patent No. 738,391, dated September 8, 1903.

Application filed October 21, 1902. Serial No. 128.167. (N model.)

T0 'a/ZZ whom, it flux/y concern;

Be it known that I, CHARLES E. ALLEN, of Wallingford, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Heat-Insulators for Handled Vessels; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-- Figure 1, a side view of a portion of a handled vessel having insulators applied thereto in accordance with my invention; Fig. 2, a sectional view of a portion of the socket and handle and also of the insulator therein; Fig. 3, a sectional view of the insulator detached and showing the insulator-cups pinned to the insulator-plug; Fig. 4, a sectional view with the cups and plugs separated preparatory to assembling.

- in heat-insulators for handled vessels, and

particularly to insulators for the handles of tea, coffee, hot water, and other vessels of hollow ware which are provided with metal handles and in which the handle portion proper or grip is insulated from a socket attached to the vessel to prevent the handles from becoming heated by the passage of heat from the vessel to the grip, the object of the invention being a simple arrangement of parts whereby the insulator may be readily formed and easily applied by soldering both to the handle and to the vessel, so as to avoid the use of rivets, pins, or screws, and yet perfectly insulate the handle from the vessel and at the same time make a water-tight handle; and the invention consists in the construction hereinafter described, and particularly recited in the claims.

In carrying out my invention I employ an insulator-plug A, of vulcanized fiber or other the center of the plug is an annular bead B, on each side of which is a rib C, forming a groove D. The ends of the plug taper, and near each end I preferably form an annular groove E. 1th the plug thus formed I employ metal cups F, corresponding in size and shape to the form of the plug, and with shoulders G, adapted to set against the small rib C. The edges H of the cups are then turned over the ribs C into the grooves D so as to interlock the cups with the plug. If desired and to further interlock the cups with the plug, the metal over the grooves E may be set inward, as shown in Fig. 2, or pins I may be passed transversely through the cups and plug, as shown in Fig. 3. One end of the plug thus formed is inserted into a socket J, secured to the body K of the vessel. and secured therein by solder M. The end of the handle L is set over the outer end of the plug and secured thereto by solder, the ends of the socket and handle abutting against the outer surfaces of the shoulders G. A similar insulator will be inserted between the lower end of the handle and the other socket.

It will be seen that with an insulator as thus described the plug perfectly closes the end of the socket and the ends of the handle, so as to make them water-tight, that the parts may be readily secured by solder, and the metal of the parts are positively insulated from each other.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- l. The herein-described heat-insulator for handled vessels consisting of an insulatorplug having annular ribs, metal cups coupled with opposite ends of said plug by overlapping said ribs, the said cups secured to the socket and-end of the handle, substantially as described.

2. The herein-described heat-insulator for handled vessels consisting of an insulatorplug having a central bead and ribs 011 opposite sides thereof, metal cups set over the end of said plug and having their edges turned over said ribs, the ends of said cups I11 testimony whereof I have signed this adapted to be inserted into the socket and end specification in the presence of two subscrib- 1o 0f the handle, substantially as described. ing witnesses.

3. In an insulating-handle the combination V w x of an insulator plug provided with annular LHARIES ALLEN ribs and metal cups secured to the ends of Vitnesses: said plug by having their edges turned over H. A. NORTON, said ribs. GEO. W. BAUMAN.
