Patented Nov. 1, 1910.

l Application filed September 23, 1905. Serial No. 279,752.

Be it known that l, \V1LL1AM H. BOUTELL,

i of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Apple- Paring Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, referenceibeing had to the accompanying drawings, forming a part of this specification, and to the 'refer-` ence-numerals -marked thereon.

My present invention relates to improvements in machines for paring apples and similar fruit, and particularly of the kind shown in my prior applications, SerialI No. 262,682, renewed May 27, 1905, and Serial No. 239,567, renewed Sept 12, y1907, and the .purpose of my present invention vis to provide certain improvements in the mounting ofthe paring knife and of the revoluble vspindles which center and revolve the Iarticlesof fruitduring the paring operation, and also to provide an improved clutch which is so constructed that 1t may be op erated with the greatest convenience an safety by the attendant, in throwing the machine into and out of operation.

i To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully explained, the novel features being pointed' out in the claims at the lend of the specification.

Iii the drawing: Figure 1 is a s/ide elevation of a paring machine embodying my improvements. view on the line 2-2 of Fig. 1. Fig. 3 is a plan view of the reel and its'connected parts. Fig. 4 is a sectional view on the line 4--4 of Fig. 1. Figs. 5 and 6 are central longitudinal sectional views of an improved clutch, the members being shown respectively as lconnected and disconnected.' Fig. 7 is a detail view of the' paring knife and the improved manner of mounting it. Figs. 8 and 9 are detail views of parts of the paring knife mounting,-an Fig. 10 is a section through the axis of one of the spindles and its bearing.

The same numerals ofrefrence -n the .i

Fig.'2 is a transverse sectional prising generally a frame 1 and a reciprocatory carriage 2 mounted to operate on suitable ways thereon, the frame being rel- .atively stationary and provided with the fork reel with its revoluble fruit receiving forks and suitable operating mechanism for intermittently rotatin the reel and operating the forks, and for reciprocating the carriage, while the carria e carries the paring knife and suitable mec anism for operating it.

In the present form of my invention the driving wheel is formed to receive a belt and is loosely mounted on a stud 4, the latter being fixed suitably to the stationary frame. On this stud is also mounted a wheel 5, having the spur gears 6 and 7 thereon and the bevel gear 8, the latter meshing with a wheel 9 which serves to reciprocate the carriage while the gear 6 cooperates with the wheel 10 which serves to rotate the fork reel, the gear 7 coperating with the pinion 11,

the latter being connected through suitable gearing to the pinion 12, which 1n turn cooperates successively with the pinions 13 and 14 of the spindles 15 and 16 of thefork reel 27, these parts being substantially the same as that described in my said application.

The wheels 3 and 5 are provided at their proximate sides with projections 17 and 18 respectively which are arranged to be engaged and disengaged by a relative axial motion of the wheels, and it is preferable to provide these wheels with thev extended hubs or sleeves toward each other and are adapted to support the helical compression spring 21, the latter lbearing at its opposite ends against,

and normally exerting a pressure tending. to separate the wheels, and thereby disengage the cooperating projections thereon. The outer end of the stud is provided with a diametric slot 22 in' whichfis a pivoted cam 23 having .a portion 23a close to the pivot,

and a similar portion 23b on the opposite side of the pivot and at a greater distance 19 and 20 which 'extend therefrom, a projecting portion 23c intervening the portions 23a and 23, the cam being provided which it may be conveniently operated into either Vof the positions shown in Figs. 5, and 6. Resting in the slot 22 of the stud between the cam and .wheel 3 is a. lslidable sleeve 25 having a cylindrical portion surwith a handle 2 4 by means of. 105

i constructing thev parts it will be obvious by it may be rotated intermittently half a roundin the stud and engaging the outer side of tie wheel 3, and also having a diainetricallyformed shoulder 26 extendinthrough the corresponding slot in the stu and adapted to eoperate alternately with` the portions 23a and 23b of the cam. By so that when the cam 23 is swung into the position shown'in Fig. 5, that portion 23b .of the cam which isA farthest fromthe `pivot Willcoperate with the shoulder 26 of the sleeve 25, causing the latter and the wheel 3 lwith which it coperates to move toward the wheel 5, thus moving the projection 17 into the path of the projection 18 on the wheel 5, rotary motion im arted to Wheel 3 being transmitted throng these coperat ing projections to the wheel 5, the two whee s 'and their coperatingprojections serving as clutch members. However, when' the cam 23 is moved into the position shown in Fig. 6, the part 23aL of the cam nearest the pivot will rest against the shoulder 2G Aof sleeve 25, allowing the wheel 3 to separate from wheel 5 under the action of the oompression spring 21 which is interposed between them, and this will cause the disengagement of the cooperating projections, so that` the wheel 3 may continue to revolve Withouty transmitting motion to wheel 5,' and the operation of the machine will beinterrupted. s y

The fork reel 27 is rotatably mounted on the shaft 27a the latter being connectedby suitable mechanism such as that describedv in my application above-mentioned, whererevolution at predetermined intervals timed according to the operations of the carriage and the paring knife, so that the spindles 15 and 16 with their respective -fruit forks are alternately brought into operative position and 14 in mesh with the drlving pinion 12 by means of which rotary motion is impart ed to the spindles,l causing the Afruit 'to 'revolve while it is being pared, and as these l spindles are revolved at high speed so'that the surface of the fruit moves very rapidly past the paring knife, and the knife blade in paring the ends of the fruit is arranged transversely to the axis of rotation, it has been found necessary to provide inexpensive and eilicient means for taking up all end thrust and longitudinal motion of the forks l' in -orderto insure uniformity in the paring of the fruit, and for this purpose I provide the reel with. a pair of cross arms 28 and 29' by means of which the fork Abearings are securely held. On the opposite ends of theV arm 28 are formed the clamps 30 and 31 l which are in alinement with the bosses 33 on the arm 29 which receive the ends of sleeves 32. The clamps engage' the forward ends of the sleeves and comprise perforated j the grooved portions 34 formed integral with the arm 28 and corresponding grooved plates or members 35 fitting the sleeves opposite the portions 34 and providedwith a slot 36 in which is a clamping screw 37.

The pinions 13` and 14 bear` against the rear side of the cross arm 29 as shoulders toV limit the longitudinal motion of the spind-les in one direction, and on the spindlesare provided fixed collars 38 and 39 against which are set the bearing .members 35, and as the latter are adjustable axially. of the spindles, by setting them up against their vcorresponding collars 38 and 39 onthe respective spindles until the pinions bear against the rear sides of the bosses 33,l all looseness longitudinally of the spindles is taken up, and the end thrust from the forks is received, on the adjustable bearing members.

In Figs. 7, 8 and 9 are shown an improved mounting for the paring knife, which consistsof-the vertical bearing 42 secured to and movable with the carriage 2l by means of the bracket '43 and screw 44, and in this bearing is journaled a shaft 45 having a radial arm 46 clamped thereon in adjusted position by means of the screw 47, the free end of this arm being forked and provided with preferably 'a pair of open trunnion bearings'v 48 which are arranged in the plane of rotation of the arm. The'paring knife 49 is provided with a shank 50 on which is loosely .mounted a sleeve 51 having trunnions or projections 52 thereon adapted to rest in the trunnion bearings 48 of the arm 46, a lateral arm 53 being fixed to the upper end of the paring knife shank behind the knife blade 49, and provided with a series of recesses to receive one end of a tension spring 54. The other end of this spring is attached to the free end of an arm 55 which constitutes the turntable, the latter being fixed to the lower end of the shaft 45.a.nd provided with an extension 56 which is arranged to rest betweenV the projections 57 and 58 of the stationary frame. This arm is provided with a radial slot 59 in which the shank 50 loosely rests,

and this slot has an opening 60 through which` the shank may pass in entering and leaving the slot, except when the projections 52 are resting in the bearings 48.v

As the carriage 2 is movable relatively to 'the frame 1, the extension 56 of the turntable resting between the projections 57 and 58 on the stationary frame will operate as the tooth of a gear and causevthe turntable j to rotate and swing the paring knife throughv a -semi-circular are to perform the paring operation, the return motion of the carriage causing the knife and its operating parts to return to normal position as shown in Fig. l, the trunnion bearings for the knife permitting the latter to yleld sufficiently to compensate for the irregularities in the surfacesI of the articles heilig pared, the uppei end of l spring operating on the arm to yieldingly the spring 54 being set at the proper notch 1 hold the paring knife in operative position in the arm to set the knife under proper i on` the turntable.

pressure. As the knife blades are quickly` dulled and must be often replaced with sharp ones, it is important that the knife Should be so mounted that they can be quickly and easil57 removed and replaced,

and this has been provided for in the present Construction, 'lor in order to remove the knife it is only necessary to lift the trunnions out of their bearings 48 in the :irni ett, and this will release the tension on spring 54 and b v Swinging the upper end ofthe shaiil'to 1 the lett in Fig. T opening (30 from the slot 59.
