Application May 27, HMS, Serial No. 672,337

(Ci. lf3- 32) The present invention relates to improvements in molds, and has particular reference to a mold adapted for shaping ground meat or the like, generally known as Hamburger into standard flat units or patties of desired form and size, although it may be used for diderent purposes.

It is further proposed to provide a mold of the character' described that is simple in construction, sanitary, efiicient in use, easy to take apart and clean, and which will produce :meat patties of uniform size ,and thicmess.

It is a further object or our invention to provide a mold o the character described which may he easily adjusted for producing patties of diierent thicknesses.

It is further contemplated to provide a mold in which a mold plate cooperates with a mold chamber in flattening or smashing c. charge of ground meat, and in trimming the edges, the mold plate being mounted for eutomatic retiu'n to in active position for facilitating and speeding' up charging operations.

And `finally. it is an object of our invention to provide securing means whereby the mold may be speedily attached to and detached from a supporting base. for firmly holding the mold when in use, and ic allow of easy removal for cleaning operations.

Further objects and advantages of our invention will appear es the specification proceeds, and the new and useful features of the saine will he fully dei-ined in the claims attached hereto.

The preferred form of our invention is illus-1- trated in the accompanying drawing, orming part of this application, in which:

Figure l shows a horizontal section through our mold, taken along line i--i ci Figure 2, the basebeing omitted;

Figure 2, a vertical section taken along line 2-2 of `Figure i.; and

Figure 3. a fragmentary section taken along line 3 3 of Figure 2. e

While we have shown only the preferred form of our invention, it should he understood that various changes `or modifications may be made within the scope of the claims hereto attached, without departing from the spirit of the inven tion.

Referring to the drawing in detail. our inverttion comprises in its principal features. a base i. a mold chamber 2 secured thereon, and e. mold plate 3 adapted for cooperation with the chamber in shaping a charge of ground inset or the like.

The base i may be of any suite/ble form, and is lil lli

d preferably made of wood, and of sufcient size and weight to firmly hold the mold in place during molding operations.

The mold chamber l2 comprises a ring fi internally threaded as at t to receive a oor plate d which may he screwed into the ring from the bottoni to any desired height. the upper face of the floor plate and the projecting portion of the ring defining the effective space available for receiving the material.

The door plate has suitable finger holds 'i suspended therefrom by means oi which it may be operated, when the mold chamber is removed from the base.

For securing the mold chamber upon the base i, we provide two iianges il and d extending from the lower end of the ring in opposite directions.

The flange is formed with s. longitudinal slot it adapted for sliding engagement under a bolt head it suitably secured upon the base, while the flange s has a hole it fitting over a boli; it secured in the base, the latter lange being held in place by means of s. wing nut lli.

The flange 3 has a bracket iii projecting therefrom in which is supported, with freedom of re volvlng motion, a vertical post i5, held in place by a nut il.

The upper end of the post i@ is slotted to receive the outer end of an arm i8 which is pivoted to the post on a horizontal pin it. The arm supports the mold plate t which is circular in form and of e. diameter somewhat in excess oi the ring il.

Opposite the arm ill, the mold plate has a i handle it' projecting therefrom, the handle preferably comprising a shank 2d lxed to the mold plate and a hand piece 2i of insulating meterial threaded thereon. as at 22.

The post it has an arm 23 projecting outwardly therefrom so as to turn with the post, and a spring 253 connects the arms 2t and it, so as to automatically pull the mold plate away from the mold cha-miser and into inactive position. thus normally clearing the mold chamber for charging operations.

In use, the operator first adjusts the door plete 5 in the ring l to provide a mold chamber of desired depth. He then slips the slotted end of the harige il underneath the head ii. lowers the ange t upon the screw i3, and applies the wing nut iii.

The mold plate :i lacing held normally in raised position by the spring 2li, the operator rst applies a piece of waxed paper, somewhat larger than the rime l to the mold chamber. and their ,daarnaar scoops up a preferably measured amount of ground meat and drops it on the ioor plate in approximately central position.

Next he applies a second sheet of waxed paper on top and pulls on the handle i9' to bring the mold plate down upon the ring 3. The descending mold plate spreads the ground meat in the mold chamber, while avoiding direct contact. For more perfect results, the operator will slide the mold plate back and forth, causing the same to swing with the post I6, whereby a more even and uniform distribution of the meat through the chamber is assured, and the edge of the party thus formed is trimmed against the edge oi the ring.

After the meat patty has thus been molded, the operator releases the handle, which causes the spring 24 to lift the mold plate, removes the meat patty between the two sheets of waxed paper, and

the hamburger is ready for cooking. In stacking the patties, the operator may conveniently use the upper sheet of one operation for the bottom sheet of the next operation.

This operation can be carried out very quickly, and if a considerable number of hamburgers are to be prepared, as for a restaurant, the iact that the mold plate snaps back automatically is a greataid in speeding up the process.

Our device may be adjusted to make meat patties of any thickness, and is readily removable from the supporting base for cleaning purposes. It may be made of any suitable material, but we preferably use stainless steel.

The handpiece 2l may be detached for storing and shipping purposes.
