To all whom it may concern:

Be it known that I, JAMES IV. lVEs'r, a.

citizen of the United States, residing in Des Moines, county of Polk, and State of IoWa, have invented a 'new and useful Improve` ment in Ice-Cream-Cone Machines, of which the following is a specification.-

The object of this invention is to provide, an improved constructionfor machines for making ice-cream cones.

A further object of this invention is to provide an improved construction for molds in an icecream-cone machine.

A further object of this invention is to l provide .an improved mold for an ice-creamcone machine, Which mold is formed with mating halves adapted to separate on a vertical line for the removal of the completed cone.

A further object of this invention is to provide means for conjunctively opening 4a plurality of molds for the removal of the completed cones and for Iconjunctively clos'- ing the'same. l

A further object of this invention is to provide an improved heating and baking arrangement for En ice-cream-cone machine.

A further object of this irjentionis to provide improved means for r moving and replacing cores relative to olds of icecream-cone machinesand for applying pres-v sure to said cores.

My invention relates to an improvement in cone machines in Which a bed of molds, or a plurality of such beds, are formed in mating, laterally separable hal-ves and a core plate-is suspended above and adapted for vertical yreciprocation with respect to said Vmolds; lever devices being provided for reciprocating the mating halves vof the molds, andpressure devices'being provided lto act. upon the core plate; and heat producing medium is conducted and applied to said moldsA for producing the finished product. My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointedy out in my claims and illustrated by the accompanying drawing, in Which- Figure I is a side elevation of the coniplete machine, partly in section. Fig. II 1s a front elevation of the same. Fig. III is a perspective of a portion of a machine equlpped with a larger number of mold: b eds, illustrating flexible lheating connections therefor. Fig.' IV is a vertical sectionon an sol enlarged scale, of the machine equipped with a modified form of pressure-,applying devices, portions being broken away to economize space. The dotted lines indicate some of the parts in elevated position. Fig. Vl is an elevation of beds of molds and means for laterally reciprocating the mating halves thereof relative to each other,dotted lines showing -such halves in extended positions.

In the construction of the machine as shown a frame is provided and said frame may be constructed of channel and angle bars as shown or of any other suitableV material. Posts 10,' 11, 12 (and another not shown) rise at the respective corners of the frame and are suitably connected to each other as by sills 13, 14 at their bases, longitudinal bars 15 and cross-bars 16 spaced above said sills. A plurality of mold beds A, B, C (in this instance three in number) extend laterally of the frame, the ends of said -beds being slidingly mounted on the longitudinal bars 15. Each mold bed A, B, C is formed of mating members 17, 18 which members are substantially channel shaped in cross-section and placed with their closed Asides toward eachother.. Each mold bed is formed With a series or rovv of inverted cone-shaped vmolds 19 (see Fig. IV) throughout its length, half of each mold being in each member of.' its mold bed.- The interior of each mold 19 is formed With a plurality of annular grooves 2O spaced from top to bottom of its periphery. The upper groove 2Q is atthe very top of the mold and is materially deeper' than the others. Re- `ciprocating'bars 21, one at each side of the frame, extend across the ends of the mold beds A, B, C and are fixed tothe ends of each forward member 17 of such beds. Ciprocating bars 22, one at each side of the frame, extend across the ends lof' the mold beds and are fixed to the respective ends of l each rear member 18 thereof. A rock shaft 2 3 is journaled transversely of the forward end of the frame in bearings 24 and a lever 25 is fixed to one end of said shaft and isv adaptedy for manual actuation to oscillate said shaft. The rock shaft 23 is formed with oppositely. projecting ears 26,27 on each end and curved links 2.8l `ivota1ly connect the ears 26 to one end of e reciprocating bars 21 while vcurved links 29 pivotally connect the ears 27 to one end of the reciprocating bars 22. Thus when the lever 25 is moved to the rear (toward the machine) the shaft 23 will be rocked and the bars 21, 22 will be reciprocated in opposite directions, carrying with them and moving apart the members of the mold beds. An opposite movement of the lever 25 will have the effect of bringing together the members 17, 18 of each mold bed.

A core plate 30 is provided andis mounted between the corner posts of the frame and adapted for vertical reciprocation. The core plate may be supported and moved up and down inv any'desired manner. In Figs. I and I1 I have shown the core plate suspended by, ropes 31 fixed to the corners thereof at one end and passing upwardly and over pulleys 32 suitably journaled at' the top of the frame. lleights 33 are fixed to the opposite ends of the ropes 31 and counterbalance the weight of the core plate 30. The core plate 30 may be provided with reinforcing ribs such as 34, 35 on its upper surface if desired. The core plate 30 is formed with a plurality of downwardly projecting cores 36 arranged in rows to correspond with the number and location of the molds of the beds A, B, C, one core being provided for and adapted to enter each mold 19. The cores 36 are of inverted cone- Ashape and are hollow, the interiors thereof opening to the top of the plate '30.

When the core plate 30 is suspended as above described the following means is pro* vided for raising and lowering said plate: Bearings 37, 38 are fixed to the posts 10, 11 below the level of the moldbeds and a rock shaft 39 is journaled in said bearings and extends transversely of the front of the frame. A lever 40 is fixed to and rises from one end portion of the rock shaft 39 and is adapted for manual actuation to oscillate said shaft. Bell-crank levers 41, one at each side of the machine, arexed by their angles to and depend from the shaft 39. A rod 42 is pivotally connected at one end to the rear arm of each bell-crank lever 41 and extends upwardly therefrom to a point of attachment to the forward portionof the core plate 30. Bell crank levers 43 (one of which is shown in Fig. I)` are fulcrumed to bearings 44 on opposite sides of and extend forwardly from the rear end of the frame. A

-rod 45 is pivotally connected at its forward The forward ends of the-sills 13,-`

the shaft 49 and is adapted tobe clutched thereto by ratchet and pawl devices 5 1 for oscillating said shaft rearwardly (toward the machine). Disks 52 are mounted eccentrically on and fixed to the aaft 49 and are adapted at times to engagf: rollers 53 on extremities of the forward arms of the bell-crank levers 41. Thus when the core plate 30 is lowered by operation of the lever 40 and the bell-crank levers 41 are extended downwardly, rearward oscillation of the shaft 49 by means of the lever 50 and connections will cause the eccentrics 52 to engage the rollers 53. Continued oscillation will cause the rollers 53 to ride up on and to the highest points of the eccentrics 52 and' move the forward arms of the bell-crank levers 41 upwardly a slight distance. This will apply a downward pull on the! rods 42, 46 and core plate to apply desired pressure of the'cores 36 into the molds 19, and will also have the effect of locking the core plate and cores in lowermost position. v"When the clutch devices 51 are released manually the rollers 53 will ride down off the eccentrics 52 and the core plate 30 and cores may be raised by operation of the lever 4G.

For supplying heat to the machine pipes 54, 55 lead from a source of supply (not shown)`preferably of gas, and said pipes are formed with branches which enterand c traverse the mating members 17, 18 of the mold beds, passing in close proximity to each mold 19. The pipes '54, 55 are formed with flexible portions 54a, 55a to permit some freedom of movement when the members of the beds of molds are reciprocated. The pipes 54, 55 are adapted to conduct innammable substance such as gas and are formed with ports 56, 57 (see Fig. V) opposite each core 19 whence said substance may escape and be ignited. A similar supply pipe 58 conducts heat producing medium to the core plate 30 and is formed with branches leading across the. top of said plate above the bracing said branches at intervals. The pipe 58 is formed with a port 60 (see Fig.

V) above and directed toward each core 36 so thatv fiame may be directed downwardly into and heat said core.

In the operation of the machine as described the core plate and cores are raised as described and a box or pan (not shown) containing suitable batter is inserted beneath them and resting above thevbeds of molds. The plate 30 'is then lowered until the cores 36 dipinto said batter when it is again raised and the box or pan of batter is removed, a quantity of batter adhering -to each core. Thenl the plate 30 is again lowered and each core 36 enters its mold 19 i and is pressed down therein as described,

Vthat the cores 36 ll a considerable portion 61 and core plate 30, or of applying pressure of the cones, after which the lever 25 is actuated to reciprocate thebars 21, 22 and separate the members 17, 18 of the various beds of molds conjunctively, the interposed cores 36 preventing the cones from adhering to and following either member of the molds. When the members of the molds have been separated a suflicient distance the completed cones will drop down between them and may be received into suitable receptacles provided therefor. Thel operation may theny be repeated. as often as desired.

In Fig. V I have illustrated a different means of raising and lowering and applying pressure to the core plate 30. A yoke 61 is fixed at its ends to the upper surface ofthe core plate 30 and a vertical screw 62 is threaded into the upper or closed portion of said yoke. The upper portion of the screw 62 fis journaled in a vertical bearing in a crossmember 63 in the upper portion of the frame. The screw 62 is provided with a collar 64 below and a-bevel gear 65 above the cross member 63. The bevel gear 65 meshes with a bevel gear 66 on the inner end of a horizontal shaft 67 journaled for rotation in the top of the frame. -A crank wheel 68 is fixed to the outer end of the shaft 67 and is adapted for manual rot-ation thereof to turn the screw 62 for the purpose Aof raising or lowering the yoke to the lowered plate.

In Fig. III I have shown a machine equipped with beds of molds containing ten molds each, and the number of such molds,

as well las thenumber of beds, may bevaried y as desired.

I do not desire to be limited to the precise construction and arrangement of parts shown and described as various means may be employed for raising and lowering the core plate, for reciprocating the mold members, and for supplying heat thereto, without departing from the spirit of my invention.
