HOLLENBECK- SANDWICH COOKER Filed Aug. 16, 1955 2 Sheets-Sheet 2 l 2 A9 \i\ i M Donald M Hollegzbec/f ATTORNEYS United States Patent SANDWICH COOKER Donald W. Hollenbeck, Auburn, Calif. Application August 16, 1955, Serial No. 528,669 1 Claim. (Cl. 99-4183) This invention relates to a sandwich cooker, and is an improvement over the construction shown in Patent No. 2,125,589, issued August 2, 1938, for Sandwich Cooker.

An object of this invention is to provide an improved means for automatically locking the receptacle members together when the movable receptacle member is moved upwardly to closed position.

Another object of this invention is to provide an improved means for limiting the downward movement of the movable receptacle member to open position.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certainnovel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawings:

Figure 1 is a detail front elevation of a sandwich cooker constructed according to an embodiment of this invention.

Fig. 2 is a detail rear elevation of the device.

Fig. 3 is a detail side elevation of the device.

Fig. 4 is a detail front elevation showing the device with the core members in raised position.

Fig. 5 is a top plan view of the device.

Fig. 6 is a transverse vertical section through the device showing a core member in lowered operative or cooking position.

Fig. 7 is a fragmentary sectional view showing the spring-pressed pivot for the core operating lever.

Fig. 8 is a fragmentary side elevation showing the lower link connected to the receptacle with the link in core raising position.

Fig. 9 is a fragmentary side elevation showing the latch in latching position.

Fig. 10 is a fragmentary vertical section showing the electrical connection from the base to the movable core cross-head.

Referring to the drawings, the numeral designates a base having a pair of tubular members 16 secured thereto and rising vertically therefrom. The tubular members 16 have slidably mounted therein tubular slide members 17 and the slide members 17 are connected together by a cross-head 13. A receptacle 19 is fixedly 2,865,518 Patented Sept. 10, 1957 7 ing a sleeve 29 and a stationary rod 30. The construcsecured relative to the posts or tubular members 16 by bolts 20 and the fixed receptacle 19 is fixed relative to the base 15 by means of bolts 21. A movable or swingable receptacle member 22 is hingedly secured as at 23 to the lower portion of the fixed receptacle 19 and the two receptacle members 19 and 22 have disposed therein heating means 24 and 25, respectively. The cross-head 18 has depending therefrom :a plurality of tubular cores 26 which are movable into the sockets 27 formed in the receptacle members 19 and 22 when the latter receptacle member is swung upwardly to a closed or cooking position. Each core member has disposed therein an election herein described is identical with that shown in Patent No. 2,l25,5 89.

In order to provide means whereby the receptacle member 22 may be limited in its downward swinging movement to an open position, I have provided an elongated rod 31 which is pivoted at 32 to one side of the receptacle member 22. Rod 31 is slidable through an opening 33 formed in a downwardly inclined bracket arm 34 which is fixed to the cross-head 18. The rod 31 has a nut 35 threaded thereon which upon downward swinging, receptacle member 22 is adapted to bear against the bracket 34. The core assembly embodying the crosshead 18, the slide members 17 and cores 26, are adapted to be vertically moved to a lower cooking or operative position, by means of an elongated lever 36 having a detent 37 in one side thereof, which is engageable by a spring-pressed ball 38 extending from the adjacent side of cross-head 18. The lower end of lever 36 has pivotally connected thereto, one end of a link 39 which is pivoted at 40 to the upper end of fixed receptacle member 19. When the cross-head assembly is in raised operative position, as shown in Fig. 4, link 39 will be disposed in substantially vertical position, as shown in full lines in Figs. 4 and 8. Link 39 is formed with a stop member 41 engageable with an abutment 42 carried by the receptacle member 19 so that link 39 will be held against swinging to the right beyond a predetermined position. Receptacle member 22 is releasably locked to receptacle member 19 by means of a latch member 43 which is pivoted as at 44 to one side of receptacle member 22. Latch member 43 includes a hook 45 which is engageable with a keeper lug 46 carried by the fixed receptacle member 19. A laterally projecting stop pin 47 is disposed above latch member 43 and is adapted to limit upwardswinging movement of the outer handle portion 48 of latch member 43 in an upper position. The handle portion 48 of latch member 43 is weighted so that latch member 43 will be gravitatingly urged to lowering position. A latch holding hook 49 is disposed in depending position from cross-head 18, and has the bill 50 thereof disposed below handle 48. When handle 48 is raised upwardly to release latch member 43 from keeper 46 handle 48 may be released from the latch and the weight thereof will swing handle 48 downwardly to a sub stanti-ally horizontal position. In this horizontal position of latch member 43 when movable member 22 is swung upwardly to a closed position, the bill 45 of latch member 43 will strike keeper 46 and move downwardly therebeneath until bill 45 is on the heat side of keeper 46. At this time the handle 48 will swing bill 45 upwardly and thereby automatically lock receptacle member 22 to vertical member 19.

In the use and operation of this cooker the material forming the dough, is of a character similar to that used for making waffles. This material is poured into the open upper side of movable receptacle member 22 when the latter is in a substantially vertical position with the core member 26 raised. This member is then swung upwardly to a vertical closed position and latched by means of the latch 43. At this time the core members 26 are lowered to extend into the sockets 27 of the confronting receptacle members 19 and 22. The time of operating the heating means for the device is regulated by means of a timer member 51 disposed on the upper side of the base 15. The timer means for the electric current is a conventional timer means (not shown).

What is claimed is:

In a device of the ch'ar acte-r described, a base, tubular posts rising from said base, a body having a stationary section and a movable section, the stationary section being mounted above the base between the posts and the movable section being hinged along the lower edge of the stationary section for swinging movement upwardly from a lowered open position to a closed position against the stationary section, confronting faces of the section'being formed with the recesses registering to form chambers open at their upper ends when the movable section is closed, a cross bar over the stationary section having de- 10 ing of said movable section.

pending arms at its ends slidably engaged in said posts, cores depending from said cross bar for entering the chambers through the open upper ends thereof and extending longitudinally of the chamber in spaced relation to the walls thereof, operating means carried by the stationary section and the cross bar for shifting the cross bar verti- 4 cally and moving the cores into and out of the chamber, means for heating the cores and said sections, a downwardly and outwardly extending lug having an aperture therein secured to said cross bar adjacent one end thereof, a rod slidable in said aperture, and pivotally connected at its lower end to a lower portion of said movable section, said rod having a threaded upper extremity, and a nut threaded onto said extremity, said nut serving as an adjustable limit stop for limiting the downward swing- Reterences Cited in the file of this patent UNITED STATES PATENTS Geddes June 18, 1907 Shuman Aug. 2, 1938
