JOHN E. BISHOP, or .MILO, MAINE.
MOUNTING STRUCTURE FOR SHAE'IS.
To all whom it may concern:
Be it known that I, JOHN E. Bisnor, a citizen of the United States,.residing at Milo, in the county of Piscataquis and State of Maine, have invented certain new and useful Improvements in Mounting Structures for Shafts; 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 same.
This invention relates to new and useful improvements in a mounting structure forshafts, and the principal object is to provide a novel structure of this type which may advantageously be used in an automatic corn popper and which will be particularly described hereafter.
In the accompanying drawings the present preferred embodi1nent,
Figure 1 is a side view partly in section of a corn popper constructed in accordance with this invention,
Figure 2 is an end view in elevation of Figure 1, showing the drum, and
Figure 3 is an enlarged sectional View on the line 3-3 of Figure 1.
Referring to the drawin the numeral 1 designates the base plate 0 the device consisting of a strip of sheet metal having formed at one end the upturned bearing wall 2, which is provided at its upper edge with the horizontally disposed forwardly extending spacing wall 3, which in turn terminates in-a vertical bearing wall 4 arran ed in spaced parallel relation with the wal 2, the lower edge of which engages the upper surface of the strip 1. Formed in the walls 2 and 4 arev suitable alined open.- ings 5 through which the main shaft 6 is rotatably mounted, and this shaft is journaled in bearings 7 arranged at spaced points along the main portion of the plate 1, which bearings are supported by the legs 8, which are riveted or otherwise secured to the strip 1, as clearly shown in the drawing. Mounted at the extreme forward end of the shaft 6 is a drum 9 formed of screen wire, which is provided with a door 10 by means of which access to the interior of'the drum is obtained.
Formed in the walls 2 and 4 below the openings 5, and in the same vertical plane, are suitable openings 11 through which the winding shaft 12 projects. This winding shaft 12 is formed at its rear end with a crank 13 and is provided intermediate its ends-with a winding drum 14, which is formed integrally with the gear wheel 15, which meshes with the gear wheel 16 mounted on the shaft 6, previously described. A. ratchetwheel 17 is attached to the shaft 12 and is adapted to be engaged by the pawl 18, so as to hold said shaft against unwinding movement. In order to prevent endwise movement of the shafts 6 and 12, suitable openings are drilled transversely through said shaft and pins 19 are introduced through said openings to engage the outer surface of the walls 2 and 4, as clearly illustrated in Figure 1, thus preventing shifting of the shafts.
In order to control the speed of rotation of the shaft 6 the top wall 8 is formed with an opening through which the collar 20 projects, which collar is provided with an axial threaded bore for the reception of the screw 21, the lower end of which carries a pressure plate 22 for engaging the shaft 6 while the upper end of said screw carries a thumb piece 23 by means of which the screw may be rotated in order to vary the pressure on the shaft 6, and thereby control its speed of rotation. It will be apparent from the foregoing that in use the drum 9 is filled with the corn to be popped and the door 10 then closed, whereupon the device is set on a stove or heater and the crank 13 turned to wind the spring within the drum 14. The rotation of the drum 14 and gear 15 will drive the pinion 16, thereby transmitting motion tothe shaft- 6 and rotating the drum 9. It will be understood that the speed of rotation of the drum 9 may be adjusted by turning the thumb screw 23 and thereby increasing or decreasing the pressure of the pressure plate 22 on the shaft 6.
Fromthe foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved automatic corn popper will be readily ap Jarent to those skilled in the art to which t is invention appertains and, while in the foregoing description, the principle of the operation of this invention has been described together with various features of construction, it is to be understood that certain minor features of construct-ion, combination and arrangement of parts may be altered to suit practical conditions provided such alteraa bearing Wall, a spacing all extending,
from the bearing Wall and over the base plate, a second bearing-Walt,fsaid second ,bearing Wall extending from said spacing all toward the base plate, a-shaft journaled in said bearing Walls, means journaled in said bearing Walls to turn the shaft, said shaft and the mainportion of said base plate extending in a direction away from said first bearing wall and beyend the second mentioned bearing walh'a-nd spaced bearings for said shaft rising from said main portion of the base plate on-the side of the second bearing all opposite t0 thefirst hearing Wall.
" in'testim'ony whereof I aflix my signature in presence of two Witnesses.
