Application ledDecember 2, 1912. Serial No. 734,493.

To all whom may concer-rr I Be. 1t known that I, JAMES 1. AYER, a citizen of the United States, and resident of Cambridge, county of Middlesex, State of Y. v device to the article heated without requii`- tachment between the bottom of the culinary l .utensils :ind the top 0r vedges of the heater.

in@r a special clamping arrangement or at- In many instances, as for instance in connection with relatively large vessels or ex- 2C).

pensive vessels, such as chaing dishes, for example, it is'impracticable or at least not ad- 'visaole to provide the usual clamping ring or the same device on the bottom of the dish or utensil,' fend also in many instances l have 'ound that better heating results may he secured -hy applying clamping pressure throughout the entire area ol the utensil, as, for instance, by applying the downward pressure directly over the upper edge of the vessel.

sery to hold the vessel in intimate .Contact with the electric stove, and the previous ways .of accomplishing this have been usurally to form an engagement between the bottom vof the vessel and a clamp attached te the Aheiter or an engagement between o.

the heater, and my invention aims to secure lrcd results of increased. elliciency and h'intimate contact with the heater' with vessels that will not'V permit of "arranging the slamp to engage with the hottom o thefvessel.

pressi To this end my invention resides in providing, connection with the stanti or heater, means for holding the entire vessei with the top edge or .qiening ot the vessel.'

lv this inventioinlohviate the expensive clips, turned grooves, and otherjormf near the iottom of the vessel, and

in many respects objectionable spur leave'the bottom of the vessel smooth and free from these grooves and protuberadces which collect dirt and render cleaning difficult.

The constructional features and 'further details of my invention will he pointed out more at length in the course of the following description, taken in connection with the aoc-(mapanyingl drawings, in which l have shown several preferred embodiments of the invention.

ln the drawings, Figure i is a view in side elevation, partly broken away, showing one form of my invention; Fig. 2 is an enlarged longitudinal sectionsview of the'movable member of the clams; Fig. 3 is affragmentary cross sectional View taken at tight angles to the section of Fig. 2; Fig. 4 is a top plan view of the parts shown in Fig. l;

.- Fig. 5 isa View similar to Fig. l of another embodiment of the invention; Fig.

( is a' fragmentary topplan view of the l movable member of the clamp of Fig. 3; Fig. 7 is a raffmentary View in side-ele vation of a thiru form of my invention; S is a top plan View of the heater stand and frame; Fig. 9 is a view in side elevation of i another embodiment of my invention;v Fig.

1G is a similar view, partly in section, of still Forgsecuring proper heating it is neces- :mother embodiment of my invention; Fig. lfl is an enlarged, broken perspective view of the frame.. rim shown in Fig. 10; and Figs. 12 and 13 are views similar to Figs. 10 and 1l respectively of still another foim of the intention.

The heater l and its supporting stand or legs 2 may bo of any usual orpreferred .kind providing a proper resistance medium 3 and flat top heating plate t on which the to be heated may be pressed liiird down for securing the de ired increased etliciency of heat conduction. Projecting upwardly from the stand l provide a frame comprising a vseries of legs preferably ithreein in imhei", and as shown in Fig. l

la receiving rings?? rigidly mounted at the upper end of these, of sufficient size tore eoive the c 'ali-ng dish or other utensil which is to be heated'hy being clamped hard down upon the plate li As shown in Figs. 94; this frame is pro vided with :l pair of 'nook 4shaped lingers or fixed jaws 7 having. their curved upper .ends or jaws at the exact height to hold or ears, pins, rings, or other projections, grooves or conformations which have heretofore been considered necessary and have been liable to accumulate dirt and render their cleaning diiiicult and their use objectionable.

By the lneans constituting my invention the vessel is held in rm contact with the surface of the electric heater by being clamped by holding devices arranged to engage either the top or. sides of the an or dish as distinguished from. clamping or locking devices engaging the bottom or lower sides of the vessel at the bottom.

My invention is capable of a wide variety of embodiments as evidenced by the several illustrative exam les herein set forth.

Having descri d my invention, whatk I. claim as new and desire to secure by Letters Patent is:

l. The combination with an electric heater for receiving a vessel to be heated, of c1amping means comprising a frame rigidly connected with the heater and provided at a plurality of points with engagin devices to cooperate with the top rim of t e vessel, a movable clamping member carried by said frame adapted to cooperate with the top of the vessel and exert adownward clamping pressure thereon.

2. The combination with an electric heater for receiving a vessel to be heated, of a clamping device comprising a frame rlgidly connected with said heater and provided with means for engaging the vessel at a plurality of peripheral polnts near the top of the vessel with a downward clamping pressure, at least one of said means coperating with the vessel to give a downward wedging action.

3. The combination with an electric heater for receiving a vessel to be heated, of clam ing means-for engaging said vessel near t e top and maintaininghthe vessel clam ed in intimate contact wit the heater, inc uding a. receiving ring rigidly connected to the heater comprising an inturned flange and provided with a plurality of engaging devices.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.

JAMES I. AYER.
