Referring more particularly to the draw-- ings the numeral 15 designates a suitable su flporting ln'acltet which 7 adapted to be secured to a support 16 by a suitzible clalnp ing screw 1'2". Corrupted with the bracket 15 is an arm 18 of 1V desired size and configuratiim but is pre'l eral'ilv angular in cross section, and adjustsbly secured to the arm 18 in any suitable manner, such as by means of a fastening screw 19, is e bracket 20 which carries a. bearing 21 in which a bar or rod 22 is slidably mounted. This baror rod carries on one endthereof a. ineuiber 28 wnich is adapted to impale the article 2% and the member 23 is recessed as at to form a sharp edge 26 adapted to enter the article. This form of holding device will more securely hold the article and at the some time will permit the article to be rotated. theresbout in u n'lenlicr to be set forth.

The bearing 21 is preferably otthe split tvpe and a. screw 2 provided for cans lug the hearingto clamp the rod 2:2 to hold the latter in its adjusted position.

A collar 28 nuiy be provided on the rod adapted to be ,e ripped hy the operator to facilitate the adjustment of the rod.

, .l-lotatablv l'llOlHlllQtl upon the bracket 15 and in suitable bearings, a shaft 29. the axis oi? which is co-ir1cident with the axis cl? tlu= bar or rod 22. Carried by theend ot' the shaft and connected thereto for rotation therewith in any uiteble manner are prongs or iinpaleinent pins 00, which are preferably spaced lateralh; from each other and are The rotation of the shaft 29 may be accomplished in any suitable manner but preferably through the medium of a crank or arm 31 having a handle 32. The crank 3 is connected with a shaft 33 to which is secured a gear 34. This gear 34 meshes with an idle gear 35 and the idle gear in turn meshes witha gear 36 connected with the shaft 29, for rotation therewith.

The gears 341, 35 and 36are preferably arranged within a chamber 37 formed in the bracket 15 or an extension thereof; and a covering plate 38 may be removablysecured in position to enclose the gears and also p91- IIllt of ready access thereto, when desired.

Slidably mounted upon the arm 18 is a cutter carrier 39 in the form of a carriage and through which carrier the arm 18. passes. the carrier being'provided with an openingconforming. in contour to the cross section of the arm 19; This prevents the carrier from axially rotating upon tlie arm- 18 and will maintain the carrier in a proper position.

The carrier is adaptedito be reciprocatcd upon the arm 18 in any suitable manner but preferably through 'themedium of a crank arm l0 which-isconnected with a shaft 4:1 journaled in a suitable bearing in the bracket 15, the axis of the shaft being transverse to the axis of the shaft 29.

A link 42 is pivotally connected as at 43 with the carrier 39 and the other end of the link is pivotally connected by means of a suitable fastening device 44 with the crank arm 4&0. 1 The link 4% may be provided with additional openings a5, and the crank arm 450 may also be provided with additional openings 46, through the medium of which additionali openings the link may be connected at different points with the crank. arm so as to vary the throw or reclpocat- I ing movement imparted to the carrier 39 when the shaft at-land crank arm Ji-Oarc rotated.

Motion may be impartedto the shaft 4-1 in any suitable manner but'preferably tom the sliaftg29 through the mediumoil a worm a? which meshes with a worm gear 48 carried by the shaft 4-1, that when the crank 31" is 'rotattd to rotate the gear 34, motion will be-simultancously in'iparted to the shafts E29 andel to rotate the article 2st and at the same time reciprocate the'cutter carrier 3%.

A cutter support d9iis'pivotally connected'by one end tothe' 'carrier 39 and at its other endis provided with a bearing 50 in which a shaft" 51 is removably mounted for freerotationthrough the n'iedium of a nut or collar 52whicli' is rcmovably connected with one end of the shaft. The support at) preferably provided with spaced stops 53 (see particularly Figure 5) for limiting the oscillating or pivotal movement of the shaft 51. This is accomplished preferably through the medium of a washer lieprovided with a laterally projecting lug 55. The washer is interposed between the support ell) and the nut 52, so that the projection will stand in the space between the stops 53, and the stops are spaced from each other a suliicient distance to permit of a limited oscillating or pivotal movement of the support 44).

Carried by the shaft 51 is a gauge 56 having a shouldered portion 57 projecting laterally therefrom and to which shouldered portion an annular cutter 58 is secured.

The cutter is preferably provided with a substantially wide periphery one edge of which is shaped to form a cutting edge 51). and projecting beyond the other edge is an extension 60 which is adapted to extend bcneath the shouldered portion a")? of the guard 56, and by means of which extension 60 and the shouldered portion the cutter may be ren'iovably secured to the guard by means Of suitable fastei'iing devices (fl.

The external diameter of the gauge 56 is somewhat less than the internal diameter of the cutter so as to form a space or passagcway between the cutting edge of the cutter and the gauge 56 to extendabout the cutter to the point at which the cutter is secured to. the gauge.

With this construction it will be manifest that the cutter will be mounted in the bcur- .ing 50 for free pivotal movement and this pivotal movement will be limited by the stops o3 engaging the projection on the washer 54. During the operation of the machine and when the cutter is held in contact with the article, and as the article is ro tated. a rotary or pivotal movement will be imparted to the cutter so as to start the paring operation and thereby prevent injury to the article being operated upon. As the cutter is reciprocated by the cutter carrici the cutter will be moved about its pivot or axis in one direction as the cuttcr col'umeuce: to operate at one end of the article and will bc held in this position until the cutter passc: out of engagement with the opposite cud ol' the article. At this time and as the direction of movement of the carrier 35) is rcversed to bodily more the cutter in the op posite direction, the contact of the article with the periphery of the cutlcr will rolatc the cutter about. its axis in the oppositc direction or until it is arrestedinlhis movement by other of the stops .33.

i The cutter is preferablv positioned so that it will operate upon the bottom portion ol the article when the article is held in the machine, and any suitable means may be provided which tends normally to hold the cutter against the article. This is uclomplished by moving thc cutter upport 4-9 about its point of pivotal connection with the carrier 39. Suitable means for accomplishing this result embodies a spring (32 which is arranged within a chamber (S3 in llll the carrier 39 and which chamber encompasses a hub portion (34. The end of the support 49 is provided with a. laterallyprojecting tubular-portion 65, which extends into the chamber 63 and encompasses the hub 64. One end of the spring 62 is seemed as at 66 to the support 49 and the other end of the spring is anchored in any suitable manner to the carrier 39. A portion of the supported) forms a closure for the chamber 63 andvthe support may be held against displacement in any suitable manner such as by means of a fastening screw 67 which passes through a washer 68 into the hub ea.

The washer (i8 serves as a means for assist- .to move the cutter in a direction toward the axis of rotation of the article and will yieldingly hold the cutter in engagement with the. article when in use, and against the stop 49 when not in use.

It is thought that the operation of this machine will be clearly understood from the foregoing, but briefly stated it is as follows. The article 24 is first placed in position in the machine by shifting the bar 22 longitudinally and then adjusting it so that the edge 26 of the member 22) will cut into the article and the prongs 30 will impale the article.

In inserting the article it is preferable that the carrier 89 be at the limit of its reciprocating movement in one direction or the other. In this position the spring 62 will holdthe cutter in the position shown in full lines in Figure 1, so. that the support 4.9 will engage the stop 49.

The crank arm 31 then rotated by the handle 32 and this will rotate the article and at the same time advance the carrier 39 from the full line position to the dotted line position shown in Figure 1. By reason of the yieldable support 49 the cutter will he graduallv brought into contact with the article. That is to say as the carrier 39 is advanced. the cutter will. not gouge into the article because when the cutter contacts with the article it will be rotated with the article and at the same time the support will be depressed by the article, causingthe cutter "to gradually cut into the skin as at 69 (see particularly Figure 4),

and follow the surface of the article as the carrier is advaliced, the spring yieldingly holding the cutter in contact with the article. As the cutter approaches the other end of the article the spring 62 will cause it to continue to follow the article. Thiswill complete the paring oi the article and the carrier together with the cutter will be at the limit of its movement. A new article may be then inserted in the machine and as the carrier returns the cutter will be moved about its axis in the opposite-direction so to gradually cut into the skin upon the return movement. Upon each forward or backward n'iovement ot the carrier an article will be completely pared.

As the skin is removed it will pass through the openingbetween the cutter and the guard 56.

By reason of thecrank 4-0 and the link connection 4-2 a diil'erent speed of movement will be given to the carrier 39 as the cutter approaches and is operating upon the ends of the article; causing the cutter to gradually enter the skin so as not to injure the article.

By reason of the crank -10 and the link 42 a different speed of advance movement will be given to the carrier 39, on account of the nature of the c'ank movement, producing an advance movement of gradual increase to a maximumanddecrease to a minimum.

In Figures 9 andlO there is shown another form of cutter 70 which is of an annular configuration and is mounted in the bearing for free andunlimited rotation therein and is so constructed that it will be supported by its axis through the medium oi. a hub 71 radiating from which are arms 72 which hold the cutter. The shaft 51 passes through the hub 71 and the cutter is secured thereto by means of a nut 73 which forces one end of the hub 71 against the guard 74. and co-operates therewith to clamp the cutter. The cutting edge 75 of. the cutter terminates adjacent and is spaced from the periphery of the gauge 74 so as to form a complete annular space 7 6 about the guard 74 and through which spacethe paring 77 passes. Portions of the arms72 adjacent the cutting edge 75 of the cutter and the pe riphery oi the guard 74: are shaped to form cutting edges 78 by means of which the parings 77 may be cut or broken up as they are removed from the article.

lVhen it is desired to permit the cutter T9. to have a complete free rotation, the washin- 54: is removed from the position shown in Figure 4 and is reversed to the position shown in Figure 9. that is so that the projecting lug will not stand between the stops 53.

A screw 79 may be provided for locking the cutter against rotation.

In the form of the invention Figure 11, the cutter 80 and the mounting therefor are similar to the form shown, in Figure 9, with the exception that the edges of the arms 81 are spaced for a considerable distance from the cutting edge 82 ot'. the rutter so that. the paring- 83 as it being cut and passes through the space between the periphery of the guard Ta and the cutting edge of the cutter, will not be broken up but shown .Will be deflected by the arms 81.
