SLICING-MACHINE.
To all-whom it may concern citizen of the United $tates, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Slicing-Machines, of which the following is a specification.
The object of my invention is to provide a slicing machine, especially adapted for slicing bread and the invention consists in the combination and arrangement of parts hereinafter described and claimed.
It has been found in practice that bread is best cut by means of a knife havin an involute curve for the cutting edge. any machines of this type have been built but it has been found very diflicult to sharpen such a knife. In my invention I provide means for automatically sharpening the knife.-
In the drawings- Figure l is a perspective view taken from the kn'ife end of the machine.
I Fig. 2 is a perspective view taken from the opposite side of the machine.
Fig. 3 is an end elevation showing the feed adjusting quadrant.
Fig. 4 a cross section showing the bread clamping means.
Fig. 5 a section showing the feed screw and feed mechanism. Fig. 6 a section of the feeding drum.
Fig. 7 a detail of the feed chains.
The numeral 1 represents a base plate, upon which is mounted supporting frames 2.
These supporting frames are provided with bearings 3, which carry a tubular feed screw 4, held against longitudinal movement by means of collar screws 5.
This screw carries at one end a ball clutch spider 6.
A feeding drum 7, is loosely mounted on a power shaft 8 extending through tubular screw 4.
Balls, 9, held in position by means of springs 10 are interposed between spider 6 and drum 7, so that screw 4 will be gripped and rotated with the drum in one direction and released therefrom in the opposite direotion. This feeding drum is old in slicing machines and I do not claimthis except as combined with other elements."
The power shaft 8 carries at one end a fly" Specification of Letters Patent.
Patented Mar. 22, 1921.
Application filed July 2, 1919. Serial No. 308,218.
wheel 11 and at the other end a knife 12,
" is carried around an. idler 18, then to a ring 19 adapted to rest in any of the notches 16. A chain 20 is wrapped around drum 7, in the opposite direction from chain 17, and is fastened at its free end to a spring 21 secured to frame. 2.
The numeral 21 represents a feeding arm, which carries a feed nut 22, normally held in engagement with screw 4, by means of a spring 23.
This feed nut can be thrown out of engagement with screw 4, by means of a lever 2 L.
Feeding arm 21 is slidablymounted on two rods 25, parallel with screw 1.
A lower gripping plate 26, in connection with feeding arm 21 by means of rods 27 and an upper gripping plate 28, is adjustable with relation to the lower gripping plate by means of rod 29.
The operation of the machine thus far is as follows: i
The bread to be cut is placed in trough 30 and the end is clamped by means of gripping plates 26 and 28.
The feed nut 22 is dropped into engage ment with feed screw l. The ring 19 is placed in the proper notch 16, for the desired thickness. The hand wheel 11 is then operated; cam 13 operates lever 14 and through the chain and feeding drum 7 the screw is rotated and the feeding arm advanced the desired amount to give the thickness of slice desired.
The knife 12 severe the slice, and it drops into trough 31, against a movable dam 32. The operation is repeated until the loaf is sliced and the slices are stacked side by side in trough 31.
Thus far similar results have been obtained in other bread slicing machines; but so far as I am aware all of them have feed screws not coaxial with the driving shaft. This construction enables me to. get a compact device easily manufactured, and brings the feeding and clamping means which are manually operated on top of the machine where they are accessible. It also leaves the entire front of the machine open for put- 5 tin the loaf into it.
- claim as my invention:
' In a slicing machine a feeding mechanism comprising a hollow screw, a ball clutch,
connected to one end thereof; a knife driv- 10 ing shaft extending through said hollow screw; a lever actuated by said shaft; a chain or cable Wrapped about one member of said clutch and adjustably connected to said lever; and means for returning said clutch to normal position, substantially as 1 and for the purpose set forth.
