The objects of my invention are:
1. To provide a simple, practical multiple-bladed cutting and slicing machine for light work such as slicing bread and various similar articles; v
2. To provide a concentric, variable drive mechanism by which adjacent sections of a I attain these objects by the means illustrated in the accompanying drawings, in

Similar numerals refer to similar parts throughout the several views.
My apparatus comprises a housing of thin sheets of metal, including a base plate, 64,v
side plates, 80 and 80', rear plate, 69, lower` Application led .Tune 10,
192e. serial No, 369,680.
lwith a horizontal front plate, 66, joining the upper and lower front plates, 67 and 63, respectively, and forming a feed table throu h which a chute, 24, rojects u wardly y means of which lthe Ibread is ed onto the feeder, 28.
An opening, 92, is formed in the rear plate, 69,.of asuitablevsize to permit the passage of aloaf ,of bread anda horizontal plate, 66', is` mounted adjacent the lower edge of the opening through which the bread or other article to be sliced may be withdrawn after being sliced. The rear opening, 92, maybe enlarged as shown in dotted lines at 95 to allow the operator to reach in and remove the bread from the receivin table, 21 or vfrom the plate, 66', if desire ln the drawings I have shown the loaves of bread .in process of being fed to the slicing bands, but it is obvious that other art-icles may be fed to the slicing bands in the same way or the feeding appliance may be varied to meetv the requirements of the particular Vthings to Vloe cut or sliced.
The housing is preferably so formed as to completely enclose the movingparts of the machine and is provided-,tokpromote'safety of the operator and to keep the working parts' rof the machine clean and free .from dust. Y
. VMy apparatus :includes a base, 38, to is united a column or frame, l, which may f` becast integral with thebase or suitablyise- 5 cured thereto. The column, 1, has formed v in'tegral-therewith, upperand lower bosses,
2 and'91, rspeCt-ivelwhich vform supports v for the bearings of the idler and driving shaft assemblies respectively.
My cutting appliance comprises stepped driving conical pulleys, 42 and 43, and idlerV `conical pulleys, 16 and 10, and mounted upon the driving conical pulleys and the idler conical pulleys is a plurality of cutting blades, 18. The blades or cutting bands, 18, may be in the form of saw blades with small teeth upon' the the front edge .thereof or they may be formed with straight sharpened cuttingV edges or vwith thev cutting edges slighly indented or undulating as desired, for any particular class of materials to be sawed, cut or sliced.,
` the driven pulley, 57.
When built for slicing bread, the blades should be placed about half an inch apart laterally so as to cut slices approximately half an inch thick. In order to slice a twelve inch loaf of bread, 22 blades will be required and the number may be increased or diminished as the work to be done requires.
For light materials such as bread, blades three-sixteenths or one-quarter of an inch wide will be ample. For such a machine for twelve inch loaves, I use 22 blades and di- `vide the drive pulley into two sections or two separate adjacent pulleys, 42 and 43, as shown in Figure 2, each of which will carry 11 blades.
`In order` to space these bands half an inch apart laterally, I provide a series of circular seats in the periphery of the conical pulleys, 42 and 43. Corresponding seats are provided in the periphery of the idler conical pulleys, 16 and 10.
In order to avoid too great a difference in the speed of the cutting bands, 18, I divide the drive pulley into a plurality of sections. In Figure 2 I have shown the drive pulley divided into two sections, 42 and 43, but it is obvious that a larger number of sections may be employed if desired.
I mount the smaller conical pulley or section, 42, upon the front end of a drive shaft, 40, Securing the section, 42, to the shaft, 40, by a pin, 39, or other suitable means.
I mount the drive section, 43, upon the front end of a drive tube or hollow shaft, 49. This drive tube, 49, is revolvably mounted in bearings, 47 and 50, seated in the boss, 91. The bearings, 47 and 50, may be of any standard type, but I prefer to use ball or roller bearings for the drive shafts, both solid and hollow, to permit the cutting bands to be driven at high speed.
A collar, 48, is formed integral with or mounted upon the drive tube, 49, which acts as a spacer to keep the section, 43, at a given distance from the boss, 91.
Within the front end of the drive tube, 49, I mount another bearing, 46, in which the front end of the shaft, 40, revolves.
Upon the rear end of the tube, 49, I mount a pulley, 52, and key or otherwise secure it to the drive tube, 49.
Within the rear end of the drive tube, 49, I mount another bearing, 53, which forms a bearing for the rear end of the shaft, 40. Upon the extreme rear of the shaft, 40, I secure a pulley, 57, by a key, 56, spline or other suitable means.
A motor, 62, is mounted upon the base, 38, and upon the rear end of the motor shaft, 62', are mounted drive pulleys, 59 and 60. A belt, 58, passes around the drive pulley, 60, and the driven pulley, 52. A'similar belt, 55, passes around the drive pulley, 59, and
I proportion the diameter of the pulleys,
60, 52, 59 and 57, and the diameter of the pulleys, 42 and 43, so that the lineal travel in feet per minute of the front cutting band upon the section, 42, will be the same as the rate of travel of the front cutting band upon section 43. Where the conical drive pulley is divided into more than two sections, the various pulleys and sections should be similarly proportioned. It is obvious that a plurality of hollow drive shafts may be used with a pulley section mounted upon each of them.
Similar stepped conical pulleys, 16 and 10, are similarly mounted upon the idler shaft, 14, in bearings, 13-13, and the idler tube or hollow shaft, 7, running in bearings, 3-3.
A lock washer, 4, is secured upon the rear end of the shaft, 14, by a nut, 5, the rear end of the shaft, 14, being threaded to receive the nut, 5. The pulley, 52, has a smaller pulley, 52, formed -integral therewith.
Bosses, 37, are formed integral with the base, 38, and have a shaft, 36, pivotally mounted therein. their lower ends splined or keyed to the shaft, 36, and are thus fulcrumed in the bosses, 37.
Supports, 34, are formed integral with the base, 38, having their upper ends united to form a prolonged bearing for a shaft, 82. The outer end of the shaft is fitted with a washer, 88, and has threaded thereon a nut, 82. The inner end of the shaft, 82, has mounted thereon a pulley, 33, secured to the shaft by a pin, 89, or other suitable means. The pulley, 33, has a crank, 31, formed integral therewith or united thereto upon which a cam roller, 32, is revolvably mounted so as to travel within a loop or opening, 30 formed in the arm, 35.
To the upper ends of the arms, 35 and 35, is united a pusher' head, 29, made up of a plurality of narrow fingers, 28, united at the front as shown in Figure 3. These fingers, 28, are made narrow enough to pass between the cutting bands, 18, and the outer fingers, 28, are formed integral with fianges, 81, which serve to "prevent the loaves of bread or other articles being fed to the cutting blades, from being displaced laterally. The rear end of the upper portion of the fingers, 28, is cut away as shown in Figure 2. The
lower portion of the fingers form a support to carry the bread as it passes through the cutting blades and to deliver it to a receiving table, 21, mounted upon brackets, 19, secured to the column, 1', with side plates, 20, to prevent the bread from being displaced laterally. As the bread. passes from the receiving table, 21, it drops upon the plate, 66', and may be removed through the opening, 92, in the rear plate of the housing.
Supports, 96, secured to the column, 1, by bolts, 98, have revolvably mounted upon their outer ends idler pulleys, 86. A belt, 51, passes around the pulley, 52', over the idler pulleys, 86,' and around the pulley, 33.
Arms, 35 and 35, have In the operation of my machine, as the motor shaft, 62', is driven by the motor, 62, it. revolves the pulleys, 59 and 60, and through the belts, 55 and 58, drives the pulleys; 57 and 52, thus driving the shaft, 40, and the hollow shaft, 49. These shafts in turn drive ,i the pulleys, 42 and 43, causing the bands, 18,
to travel around the idler pulleys, 16 and 10. As the pulley, 52, revolves, it carries with it the pulley, 52', which through the belt, 51, drives the pulley, 33. As the pulley, 33, revolves, the crank, 31, causes the roller cam, 32, to travel in the loop, 30, of the arm, 35, thus causing the pusher head, 29, to carry the loaf of bread asreceived from the chute 24, against the cutting bands, 18, where it is' sliced. When the pusher head, 29, has carried the loaf of bread through the cutting blades, it is drawn back to itsl original position as shown in Figure 2, and the operation is repeated. Each succeeding loaf of bread, after .being sliced, drives the preceding loaf along the receiving table, 21.
The side plates, 20, of the receivingtable, 21, may be formed of resilientmaterial which will aid in retaining the slices of bread in their original position as they pass overlthe" table, 21, or side springs, 20,`may be secured to the side plates, 20, which will exercise a yielding pressure upon the sliced loaf of bread to retain the `slices in their original position.
The bread may be placed upon the table' 66, and fed into the chute, v24, manually orx -by mechanical feed as'desired.
rI`he free ends o'f the lower fingers, 28, are preferably sloped downward slightly so as to pass under the receiving table,'21, as shown in dotted lines'in Figure 2, and the pusher head may be formed slightly wider than the table, 21., so that the anges, 81, will pass outside of the side. plates, 20 or either the flanges, 81, or the side plates, 20, maybe shortened to prevent interference with the other.
In describing my apparatus, I have referred to the left side of Figure 2 as the front of the machine, being the side from which the bread is fed into it, and to 'the right side of Figure 2, as the rear of the machine, being the side from which the bread is removed. l
The housing may be of plain sheets of metal with angular corners united by rivets, 90, and with ornamental, nickel plated strips, 99, added thereto for ornamentation.
In describing the cutting bands, I used the term bands to apply either to narrow band saws or to continuous bands having the front edges sharpened like a knife blade. For most purposes, these bands may be very narrow-from a' quarter to three-sixteenths of an inch in width being ample, and the bands are preferably made. of very thin, rust-proof material which will not rust nor corrode.
The conical pulleys or pulley sections may be cast hollow as shown in Figure 2, with open spaces,`11, 17, 41 and 44, left therein or they may be formed ofwood, micarta or other suitable material of any kind.
The upper and lower fingers vof the feeder head, 28, may be entirely separate or they may be joined by a web portion, 28', as shown in dotted lines in Figure 2, and all of the fingers except the two outside ones, should terminate at the point shown by the web. As so arranged, the lower fingers form a support for the loaf of bread, 27, and the webs, 28', and the ends of the intermediate upper fingers will press against the` loaf of bread, 27, to force it against the slicing blades, 18, as the feeder advances. I claim:
1. A cutting or slicing machine of the type described, comprising a base, a frame united thereto, lupper and lower bearings secured in the frame, a plurality of concentric drive shafts mounted in one lof the bearings and a plurality of concentric idler shafts mounted in the other bearing, a stepped conical pulley secured upon the front end of each of the drive shafts and `a corresponding conical pulley secured upon the front end of each of L shafts mounted in one of the bearings and a plurality of concentric idler shafts mounted in the other bearing, a pulley secured upolr the front end of each of the drive shafts and a corresponding pulley secured upon the front end of each of the idler shafts, a plurality of cutting or slicing bands mounted upon the pulleys, and means for driving the drive shaffls simultaneously but at different relative s ee s.
