Application April 23, 1957, Serial No. 654,586

21 Claims. (Cl. 146-11) The present invention relates to machines for the shelling of peanuts, and, more particularly, has reference to means whereby the machine can be readily and easily adjusted to compensate for the size of the nuts to be shelled.

This invention constitutes an improvement over the peanut shelling machine disclosed in the prior U. S. Patent No. 2,672,901, issued March 23, 1954.

Heretofore, it has been a serious problem in the art to adapt the machine to the size of peanut to be shelled, and the customary procedure is to adjust the position of the rotor or the rotatable member carrying the knives relative to the grate or basket. This is a laborious and time consuming operation which materially reduces the output of the plant and, in addition, the operation is an expensive one.

Accordingly, the salient object of the pre-ent invention is to overcome the drawbacks currently present in the art, and these ends are accomplished by the provision of means whereby the rotor is mounted inthe machine frame in a stationary or non-adjustable position, and the gap or space between the rotor and the grate or basket is adjusted to the desired degree by varying the position of the grate or the basket relative to the rotor thereby reducing to a minimum the time required for the change-over as well as the costs of effecting such change-over.

A study of the following description and accompanying drawings will disclose further objects and advantages of the invention which will be fully understood by a person skilled in the art.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like reference numerals denote the same or similar parts in the several views and in which:

Fig. l is an end elevational view of the shelling machine;

Fig. 2 is a perspective view, partly broken away, of the machine;

Fig. 3 is a perspective view of the machine with the grate or basket removed;

Fig. 4 is a perspective view of the machine showing further details;

Fig. 5 is an elevational side view of the expanders and supporting mechanism;

Fig. 6 is a longitudinal sectional view of an expander taken on theline 6-6 of Fig. 5 in the direction of the arrows;

Fig. 7 is a longitudinal sectional view of the expander mechanism taken on the line 7-7 of Fig. 5 in the direction of the arrows;

Fig. 8 is a longitudinal sectional view of an expander taken on the line 8--8 of Fig. 5 in the direction of the arrows;

Fig. 9 is a cross-sectional view of the basket showing one set of end expanders; and

Fig. 10 is a perspective view of a portion of the basket structure.

Referring to the drawings, the numeral 1 denotes the framework of the machine and includes legs, side members and end members together with suitable bracing means, with such framework preferably being in the form of angle irons of U-shape and right angle members. A sheet metal casing 2, Figs. 1 and 2, is mounted and secured on the framework 1, and a basket 3 extends longitudinally of the framework. Angularly disposed guide chutes 4 and 5, Fig. 2, serve to guide the peanuts from the conveyor (not shown) into the basket 3.

At each end of the framework there is located a drum expander in the form of a drum assembly casting with each drum having an aperture 7 centrally located therein for the reception of the axle of the rotor or cutter bar reel (not shown). Mounted within each drum unit is a multiple scroll cam 8, Figs. 3 and 5, which functions to actuate expanders 9 and 10, with expanders 9 operating from the inside portion of the cam 8 and expanders ill from the outside portion of the cam 8, as will be more fully described.

Each drum 6 is secured to one of the end braces of the machine framework by bolts 61 passing through apertures 62 in the drum, Figs. 3 and 9. Each of the expanders 9 and It) is mounted for radial movement and includes a head portion 9, 10 and a shank portion 9" and 10". As best seen in Fig. 5, the expanders are spaced about the drum, and there are preferably eight expanders. An annular coil spring 11, Figs. 3 and 5, c0- operatcs with the shanks of the expanders 9 and 10 to normally maintain the expanders against the scroll cam 3. The expanders 9 and 1t bear against the inside surface of the basket 3 at each end thereof throughout the entire perimetric extent of the basket and, as the basket is made of metal of such gauge that it can. be distorted, the outward radial movement of the expanders 9 and 10 will move the basket outwardly an equal extent throughout its peripheral extent thereby changing the distance between the aperture for the cutter bar reel (not shown) and, as a consequence, changing the di tance between the periphery of the reel and the inside of the basket.

Referring to Fig. 3, the numeral 12 indicates a lever serving to effect a change in the diameter of the basket,

and the lower end of the lever is attached to a shaft 11 which extends longitudinally of the machine and is suitably journaled in the framework at 16 and 17. A toothed sector 14 is secured to the shaft 11, and a latch 15 cooperates with the teeth of the sector 14 to lock the lever 12 as well as a lever 13 in the desired position. The latch 15 can be withdrawn from between adjacent teeth by moving a pivoted grip device 16 toward the lever 12 which moves a connecting rod 17 upwardly against the action of a spring 18 which latter functions to return the latch 15 to the locking position When the grip 16 is released.

The lever 13 connected to the shaft 11 is pivotally connected at 19 to one end of a rod 21 which latter at its other end is pivotally connected to an arm 22, by pivot 23, secured to the ratchet type cam 8, Fig. 3. Hence, it will be appreciated that movement of the handle bar or lever 12 will rotate the shaft 11 and, as a consequence, move or adjust the cams 8. To prevent the cams 8 from changing their positions, there is provided a friction looking element 24 secured at 24 and carried by a bar 25 pivoted to the framework on a spacer 26 as at 27. A spring 28 coacts with the locking element 24 to return the same to the locking position.

Referring to Fig. 3, it will be seen that an arm or lever 29 is bolted to the other end of the shaft 11 at 30.

A red 31 is pivoted to the upper end of the lever 29 as at 32 with the free end of the rod pivoted at 33 to a lever 34 connected to the scroll cam in a manner similar to the lever 22, so that the cams associated with the dru at the other end of the machine will move simultaneously when the lever 12 is actuated.

To lock and release the friction locking element lever 23 is provided, guided in a bracket se carried by the framework and a spring 37 operatively connected with the lever and the friction locking element 24? serves to maintain tension on the locking element when the lever 23 is disposed in the release position.

There is further provided means to fasten or secure the basket 3 to the respective end drums 6 and, in this con-- nection, attention is directed to Fig. 4. It will be noted that a lever 33 is provided with a toothed sectcr 35 at its lower end, and the assembly is carried by a crankshaft 4d rotatably mounted in the legs of the framework along one side of the machine. A lever 41 is pivoted at 42 to a connecting rod 43 which extends transversely of the machine and which, in turn, is pivoted at 44 to an arm 45 secured to a second crankshaft 46 extending longitudinally along the opposite side of the machine.

A plurality of spaced arms 47, 48 and 49 are interposed between the crankshaft 1% and the upper edge of the grate or basket 3, and a bar i? suitably secured to the respective arms maintains the same in proper spaced relationship. It will further be seen that arms 5i and 52 are positioned between the upp;r edge of the basket and the crankshaft 46 with a bar'53 attached to the arms 51 and 52 to maintain such arms in the proper relatiorship. Hence, it Will be apparent that rotation of the respective crankshafts 4t) and 46 will move the arms 47, 48, 49, 51 and 52 and thus fasten and secure the basket 3 about the drums 6 at the ends of the machine.

A release grip member 54 is pivoted to the lever 33 and actuates a rod 55 which carries a latch (not shown) at its l wer end for cooperation with the teeth of the sector 39 to lock the lever 38 in the desired position and a spring 56 returns the latch to the locking position when the grip member 54 is released.

A bar 57 is pivoted at Ed on a spacer element 55'- carried by one of the legs of the frame, and a friction lock 60 on the bar 57 cooperates with the rod 43 to prevent d'splacement of the rod and thereby prevent the basket 3 from being dislodged from its adjusted po-itio-n. A lever 61 is mounted in a bracket 62 on one of the legs and functions to lock and release the friction lock 6%. A spring 63 associated with the lever 61 and the lcck t'rii will maintain tension on the lock 61) when the lock is in the released position. Also, a spring 64 operatively connected with the friction lock 60 will return the lock to the locking position.

In Fig. 1 it will be seen that a lever 65 carries a plate segment 66 at the lower end; such elements are carried by a shaft 67, as seen in Fig. 2, and arms 63 are fixed to the shaft 67. A sliding door, plate closure or shutter 63 cooperates with the open upper end of the basket and bolts or other securing means 69 hold the door in position to slide on the top of the arms 2-7, 48 and 49. The plate closure 63 is formed with apertures 7a through which project extensions of the levers did.

A bolt 71 secures the lever as in position on the plate 66, and apertures 72 in the plate permit the bolt 71 to be engaged in the proper aperture to position the lever 63.

In Fig. 1 the legends U-V, WX and Y--Z, together with the arrows, indicate the direction of movement of the levers 38, 12 and 65, respectively, while the legend ST with arrows in Fig. 2 denotes the direction of movement of the closure 63.

it is believed clear from the foregoing that there is provided a plura ity of means easily accessible to the opera-' tor whereby the diameter of the end drums supporting the basket 3 can be enlarged or reduced within cert in limits to adjust the position of the basket relative to the 4 rotor or cutter bar reel to compensate for the particular size of peanuts being shelled, and the ba;ket firmly secured to the drums. In addition, locking means coact with the drum diameter varying means and the basket securing means to prevent the displacement of such means after the desired adjustments have been made. Furthermore, there is provided a minimum of control members for effecting the required adjustments, and all of the control members are in the nature of levers mounted at one end of the machine so that a. single operator can effect the desired ad,ustments without the necessity of moving all around the machine.

In connection with the rotor or cutter bar reel, this assembly can comprise a structure of the type set forth F in Patent No. 2,672,931, issued March 23, 1954, to

Lawrence Pearman et al., although, of course, it is obvious that any type of reel can'be employed. In other words, the basket and its operating means can be incorporated with existing types of shellers with a minimum of modification of such shellers. The entire assembly is quite rugged and relatively simple as to structural details and operation.

The machine fully eliminates the prior practice of removing the cutter bar reel, adjusting individually each bar of the reel and remounting the reel in the framework of the machine. With the present invention, the spacing desired between the basket and the reel is determined, and the operator then merely manipulates the proper levers to position the basket to the correct spacing, secure the basket to the drums, lock the basket in position, and the machine is ready for operation. After the peanuts have been introduced into the basket, the closure plate is moved to close the entrance opening, and rotation of the rotor is effected. As a matter of fact, in addition to the closure plate being used to close the entrance opening, it is more often used to regulate the flow of the products into the basket and rotor.

Referring to Figs. 5 to 8, the cam 8 has double ratchet cams as the outer earns for the expanders 10 and the inner cams 91 for the expanders 9 with a groove 92 therebetween. The expanders are slidable radially in slots 93 arranged radially in each drum 6 with eight such slots or grooves 93 for the eight expanders. The spring 11, as clearly shown in Fig. 5, tends to pull the expanders radially inwardly to maintain the expanders on their respective cams at all times. The outer faces 94 of the expanders contact the internal surface of the sheet metal basket 3 at the ends thereof and this basket 3 has elongated holes 88 therein through which the shelled peanuts and broken shells pass after having been cracked open by the revolving breaker reel, not shown. As shown in Fig. 8, the tapped hole 94', of which there are two receive the bolts 23, Fig. 3, to secure the arm 22 to the cam 8.

The actuation of the handle lever 12, Fig. 3, will result in the adjustment of the expanders to thus adjust the specific diameter of the basket or perforated curved plate 3.

The handle lever 65, Fig. 2, operates the closure plate 63 and the handle lever 38, Fig. 4, operates to tighten and hold the basket 3 on its drums. Fig. 1 shows all three handle levers in such a position so that an operator may make the desired adjustments from one position of the machine.

Figs. 7 and 9 show spaced bevel portions 58 spaced around each drum 6 between each adjacent pair of expanders.

The expanders are beveled so as to allow the expanders to cleanse themselves automatically of the products and thereby prevent the clogging of the expanders.

The present invention is not to be confined to any strict conformity with the showings in the drawings, and changes or modifications may be made therein in so far as such changes or modifications mark no material departure from the salient features of the invention as set forth and defined in the appended claims.

It is, of course, understood that in referring to peanuts throughout the specification and claims that the machine is applicable to be used for shelling all kinds and types of nuts and beans. The machine is thus constructed to shell all nuts of similarcharacter to peanuts as well as velvet beans, beans in general, and peas. In fact, the machine is applicable for shelling nuts and vegetables including hard and soft shells.
