DANIEL Sl/VENSON, OF KANSAS CITY, MISSOURI.

CORN-POPPER.

SPECIFICATION forming part of Letters Patent No. 470,882, dated March 15, 1892. Application filed December 9|, 1891. Serial No. 414,528. (No model.)

T0 a/ZZ whom t may con/cern:

Be it known that I, DANIEL SWENsoN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Corn-Poppers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains -to make and use the saine.

My invention relates to improvements in corn-poppers; and the objects are, first, to provide a simple and easilyoperated popper which will automatically deliver the corn as fast as popped and Will not burn the sam e,and, secondly, to provide means for automatically feeding a certain quantity of unpopped corn to the popper.

With these ends in view my invention consists in the peculiar construction and arrangement of parts, as will be hereinafter fully pointed out and claimed.

In the accompanying drawings, Figure l is a vertical longitudinal sectional view of a popper constructed in accordance with my invention. Fig. 2 is a transverse sectional view on the line o; a: of Fig. l. Fig. 3 is a det-ail view of the operating crank or shaft. Figs. 4L and 5 are plan views of one end of the popping-drum. Fig. 6 is an elevation of one end of the popping-drum. Figs. 7 and 8 are side views of the hopper and feed-valves.

Like letters of reference denote corresponding parts in all the figures of the drawings, referring to Whichx A designates an inclosing case or shell of any desired size and shape.

B designates a spider or supporting-frame, which consists of a plate or member b, provided With a central threaded aperture c and a series of outwardly-extending curved arms cl. 'The arms d are connected near their outer ends to one of the end Walls of the casing or shell A.

In the threaded aperture c, in the spider or frame B, is screwed one end of a sleeve C, which extends longitudinally of the casing A and has its other end supported in a manner to be hereinafter described.

D designates a drum or cylinder, which is arranged Within the casing A around the sleeve C. A shaft E extends through and is connected to one end e of the drum D, and to the outer end of this shaft beyond the casing A is connected a crank or handle F. The shaft E extends inside of the drum a short distance, and the inner end thereof is slotted at f f to provide a tongue S, which extends continuously through the sleeve O and extends beyond the casing or shell A. One end of the sleeve C is secured in thespider or frame B and the other end ts in the slotsf f in the inner end of the shaft E. v

The drum D is provided with two heads e c', one of which e is made solid, and it is to this solid end that the shaft E is connected. The other end e of the drum consists of an annular metallic rim or ring g, and the remainder of said head is formed of Wire-netting g. A central opening or aperture h is left in the head e', and around this central opening is arranged a flaring rim h. The

end e is braced by means of a brace G,Which is fastened at its ends to the metallic rim g and extends across the opening or aperture h. This brace may extend straight across the aperture h, as shown in Fig. 4, or fthe brace may be bent to extend into the interior of the drum, where it crosses such aperture, as shown in Figs. l and 5. In both cases the brace G is provided with an aperture H, through which the sleeve O passes.

I designates aspirally-shaped conduit,which extends from the central aperture h in the head c to the other head e of the drum. This conduit I is preferably made of Wire-netting or other suitable material, and the portion of such conduit which-forms the side Walls of the drum D is made liner than the other portions of said conduit.

L designates the outlet or discharge opening in the side of the drum D.

K designates agasoline-tank, which is supported in a suitable elevated position and is connected, by means of a supply-pipe Ze with one or more (preferably two) burners arranged within the casing A below the drum I).

M designates a hopper suitably attached to or supported from the casing A, and N designates a pipe or conduit which extends from the lower side of said hopper through the wall of the casing A and terminates within the daring rim h on the head e of the drum D.

To one side of the conduit or pipe N is attached a bracket or stud fa, on which is fulcrumed a lever O.

P P designate two valves, which are arranged in the pipe or conduit N and oonnected to the lever O on opposite sides of its fulcrum. To the lower end of the lever O is pivotally attached a crank-arm R, which is provided with a longitudinal slot fr, which opens through the lower end thereof. On the end of the tongue S is fixed a pin T, adapted to fit in the slot r in the crankarm R.

XV designates a spring, which is arranged between the pipe N and the lever O at one side of the fulcrum thereof to normally keep the lower part in position within the pipe N.

U designates a door arranged in the wall of the casing A near thebottom thereof, through which access can be had to the interior of the casing.

The operation of myinvention is as follows: The hopper M is filled with corn and the burner or burners within the casing lighted. The shaft E and the drum D attached thereto are rapidly revolved about the sleeve C by means of the handle F. The pin T lits in the slot fr in the crank-arm R, and at each revolution of the tongue S the lever O is turned on its ful crum and the valve P withdrawn from the the pipe N to allow corn from the hopper M to pass through the pipe N into the drum D. As the valve P is withdrawn the other valve P is forced into and across the passage in the pipe N, so that only the corn which was between such valves passes into the drum. As the tongue S turns further around, the spring XV forces the lever S back into its normal position and allows corn to pass from the hopper M into and fill the space in the pipe or conduit N between the valves PP therein.

As the corn leaves the pipe N it passes into the spiral conduit, and as the drum is revolved the popped corn is delivered through the outlet L of such conduit into a suitable receptacle. Should it be desired to cool the contents of the drum D, the shaft E and the drum attached thereto are moved longitudinally on the sleeve C to take the drum out of the path of the burners. This longitudinal movement of the shaft disengages the pin T from the slot o, and the drum can be revolved without causing any corn to pass from the hopper through the pipe N.

I am aware that changes in the form and proportion of parts of the devices herein shown and described as an embodiment of my invention can be made without departing from the spirit or sacrificing the advantages thereof, and I therefore reserve the right to make such changes and alterations as fairly fall within the scope of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with an inclosing case or shell, of a sleeve attached to the case or shell, a drum fitted around said sleeve and movable longitudinally thereon, a source of heat arranged within the inclosing shell, and means for revolving the drum, substantially as described, for the purpose specified.
