MOLD FOR FOOD PATTIES Filed March 31, 1959 A ORNEYS.

the ring-forming member 10.

United States Patent Filed Mar. 31, 1959, Ser. No. 893,192 4 Claims. (Cl. 17-32) This invention relates to devices used in molding meat patties and the like, these devices being generally referred to as hamburger rings. More particularly, the present invention relates to a hamburger ring which is readily adjustable for forming patties of various diameters.

Numerous hamburger rings or molds have been proposed in the prior art but these devices have generally been so constructed that they are adapted to produce patties of one given size. It is highly desirable to pro duce patties of different sizes for different purposes or occasions and for domestic use it is not feasible to provide numerous rings for such various purposes.

The present invention provides an extremely simple and efi'ective hamburger ring structure which is readily adjustable to provide a ring portion of any size within certain predetermined limits. According to the novel construction of the present invention it is merely necessary to rotate the handle member of the device relative to the ring portion thereof to release the ring portion for adjusting movement and to subsequently secure the same in a desired position of adjustment.

In the drawings:

FIG. 1 is a general elevational view of one form of the device of the present invention;

FIG. 2 is a side elevational view thereof taken generally at right angles to FIG. 1; and

FIG. 3 is a further elevational view of the device of FIG. 1 but taken at right angles to FIG. 2 and showing an end view of the device.

Like characters of reference denote like parts in the several figures of the drawing and the numeral 11 designates a ring-forming member which comprises a strip of resilient metal having overlapping terminal portions 11 and 12, the outer terminal portion 11 preferably having an outwardly bent end 13 for manipulating purposes.

The outer terminal portion 11 is longitudinally slotted as at 15 and the inner terminal portion 12 is provided with a square or other non-circular opening which receives a complementary square or non-circular portion 16 of a screw 17.

A block 20 has an arcuately concave face 21 which seats against the outer surface of terminal portion 11 of The shank of screw 17 beyond the square or non-circular portion 16 passes freely through an opening in the block 20 and threads into one end of an elongate handle member 23.

It is merely necessary to rotate handle member 23 in one direction to clamp the terminal portions 11 and 12 and block 21) between the head of screw 17 and the handle portion 23 and fix the ring-forming member in a given position; that is, with a desired degree of overlap of the terminal portions 11 and 12 thereof. This establishes the diameter of the patty which the device will form.

When it is desired to alter the effective diameter of the ring-forming member 11 handle 23 is loosened slightly whereupon the overlapping portion 11 may he slid arcuately and circumferentially along the inner overlapping portion 12 and between the latter and block 20, by virtue of the slot 15, to enlarge or reduce the degree of overlap and thus inversely enlarge or reduce the effective diameter of the ring-forming member.

In accomplishing this adjustment the user manipulates the end portion 13 with one hand while holding the handle 23 in the other. As soon as a desired effective diameter of the ring-forming member 10 is attained a simple turning of the handle member 23 again locks the overlapping portions 11 and 12 against further relative intersliding movement.

If desired the outer surface of overlapping portion 11 of ring-forming member 10 may be provided with graduations to indicate the approximate diametral dimension which the ring-forming member 10 assumes for various degrees of overlap, or the graduations may merely be marked small, medium and large, or with other suitable indicia.

I claim:

1. A device for forming food patties comp-rising a ring member and a handle member, said ring member comprising a relatively thin flat strip of resilient material in generally arcuate form with its ends overlapping to form a ring, one of said overlapping ends having an aperture and the other of said ends having a longitudinal slot, a screw disposed with its head within said ring and its shank projecting radially outwardly through said aperture and said slot, said handle member having internal threads for engagement with said screw shank to clamp the overlapping ends of said strip selectively in various relative overlapping positions to adjust the effective diameter of said ring.

2. A device for forming food patties comprising a ring member and a handle member, said ring member comprising a relatively thin flat strip of resilient material in generally arcuate form with its ends overlapping to form a ring, one of said overlapping ends having a non-circular aperture and the other of said ends having a longitudinal slot, a screw disposed with its head within said ring and its shank projecting radially outwardly through said aperture and said slot, said screw having a non-circular portion beneath its head for engagement with said aperture whereby the screw is held against rotation, said handle member having internal threads for engagement with said screw shank to clamp the overlapping ends of said strip in selectively various relative overlapping positions to adjust the efiective diameter of said ring.

3. A device for forming food patties comprising a ring member and a handle member, said ring member comprising a relatively thin fiat strip of resilient material in generally arcuate form with its ends overlapping to form a ring, one of said overlapping ends having an aperture and the other of said ends having a longitudinal slot, a spacer block in registry with said aperture and having a concave face portion seating externally against the outer overlapping end of said ring member, a screw disposed with its head within said ring and its shank projecting radially outwardly through said aperture, said slot and said spacer block, said handle member having internal threads for engagement with said screw shank to clamp the overlapping ends of said strip selectively in various relative overlapping positions to adjust the effective diameter of said ring.

4. A device for forming food patties comprising a ring member and a handle member, said ring member comprising a relatively thin flat strip of resilient material in generally arcuate form with its ends overlapping to form a ring, one of said overlapping ends having a non-circular aperture and the other of said ends having a longitudinal slot, a spacer block in registry with said aperture and having a concave face portion seating externally against the outer overlapping end of said ring member, a screw disposed with its head within said ring and its shank projecting radially outwardly through said aperture, said slot and said spacer block, said screw having a non circular portion beneath its head for engagement with said aperture whereby the screw is held against rotation, said handle member having internal threads for engagement with said screw shank to clamp the overlapping 3 I 4 ends of said strip selectively in various relative overlap- 1,110,882 Busch Sept. 15, 1914 ping positions to adjust the effective diameter of said ring. 1,139,550 McCracken May 18, 1915 1,828,106 Ertola Oct. 20, 1931 ReferencesCited in the file of this patent 2,325,841 Faber Aug. 3, 1943 UNITED STATES PATENTS r 5 FOREIGN PATENTS 681,283 Waynick Aug. 27, 1901 665,622 France Dec. 13, 1928
