4 Claims.

The present invention relates to new and useful improvements in orange parers of the type constituting the subject matter of U. S. Patent No. 1,008,555, and has for one of its important "5 objects to provide, in a manner as hereinafter set forth, a parer of this character embodying novel means for automatically returning the knifeto its starting position.

Other objects of the invention are to provide a l0 parerof the aforementioned character which will be simple in construction, strong, durable, highly eiiicient and reliable in use, compact, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan View of an orange parer constructed in accordance with the present invention.

Figure 2 is a View in front elevation thereof.

Figure 3 is an end elevational View.

Figure 4 is a view in vertical transverse section, taken substantially on the line 4-4 of Figure 2.

Figure 5 is a View in horizontal section, taken substantially on the line 5 5 of Figure 2.

Figure 6 is a vertical sectional view through the knife, taken substantially on the line 6-5 of Figure 2.

Figure 7 is a View in horizontal section through 85' the knife, taken substantially on the line 7 7 of Figure 2.

Figure 8 is a detail view in plan of the lever constituting an element of the knife returning mechanism.

Figure 9 is a detail View in elevation of another lever constituting one of the elements of the knife returning mechanism.

Figure 10 is a View in front elevation of the swinging knife supporting arm.

Figure 11 is a detail View in side elevation of the knife supporting arm.

Figure 12 is a detail view in front elevation of the slidable bearing in which the knife supporting arm is journaled.

Referring now to the drawings in detail, it will be seen that the embodiment of the present irvention which has been illustrated comprises a frame 1, which, as best seen in Figure 2 of the drawings, is substantially U-shaped in front ele- 55 vation, said frame being provided with a Suit- (Cl. 14S-43) able clamp 2 for securing the parer on a table or 3 other support. Journaled longitudinally in the frame 1 is a worm shaft 3 which is driven by a hand crank 4 and which has fixed thereon a gear 5. v

Holders 6 and 7 are mounted on the frame 1 in opposed relation to each other for securing an orange therebetween, the holder 6 being mounted on one end of a longitudinally slidable shaft 8 for movement in a horizontal plane toward and away from the holder 7. A handle 9 is rotatably mounted on the other end of the shaft 8. The holder 7 is fixed on one end of a shaft 10 which is journaled in a bearing provided therefor 'on the frame 1, a gear 11 being xed on the other end portionpof said shaft 10. The gear 11 is meshed with the comparatively large gear 5 for actuation thereby. Teeth 12 are provided on the holders 6 and 7 for penetrating the rind of the orange.

Depending from an intermediate portion of the frame 1 are spaced, opposed, integral guides 13 in which a vertical bearing 14 is mounted for sliding movement in a horizontal plane. Journaled in the rbearing 14 is an angular arm 15 having a gear segment 16 on one end for operative engagement with the worm shaft 3. On the other end of the angular arm 15 are ears 17 between which a stem 18 is journaled for swinging movement in a vertical plane. A spring 19 is provided for yieldingly urging the stem 18 toward the orange between the holders 6 and 7 and a spring 20 is mounted on the slidable bearing 14 and engaged with the arm 15 for yieldingly urging said arm toward its retracted or starting position. A pull spring 21 is connected with the bearing 14 for yieldingly urging said bearing in a direction to engage the segmental gear 16 with the worm shaft 3. The reference numeral 22 designates an adjustable stop for the stem 18 which is threadedly mounted in the arm 15.

The upper portion of the stem 18 is threaded for adjustably supporting a knife which is designated generally by the reference numeral A28. As illustrated to advantage in Figures 6 and 7 of the drawing, the knife 23 comprises a block 24 which is secured in adjusted position on the stem 18 by a set screw 25. A lock nut 26 is engaged with the lower side of the block 24. Mounted on the block 24 is a substantially U-shaped blade 27 which is secured to said block, as at 28. The reference numeral 29 designates a gage which is mounted on top of the block 24, said gage having a slot 30 therein which accommodates the stem 18 and which permits adjustment. The gage 29 is secured in adjusted position by a winged nut 31 which is threaded on the stem 18.

Pivotally mounted, at an intermediate point, beneath the frame 1 is an angular lever 32 which is operatively engaged with the slidable bearing 14 for shifting said bearing against tension of the spring 21. The other end portion of the lever 32 is in the path of a nger 33 which projects from the arm 15. Mounted for sliding movement in one of the guides 13 is a spring actuated latch 34 which is engageable in a recess 35 provided therefor in one side of the slidable bearing 14. The latch 34 is operatively connected with a lever 36 which is pivotally connected, at one end, to the frame 1. The other end portion of the lever 36 extends angularly and terminates in a cam 37 which is positioned for engagement by a nger 38 which extends angularly from the adjacent edge of the arm 15. The reference numeral 39 designates stops which are provided in the guides 13 for limiting movement of the slidable bearing 14 under impulsion of the spring 21.

Briefly, the operation of the parer is as follows: The orange is clamped between the holders 6 and 7 and the crank 4 is then actuated to rotate said orange and the shaft 3. Rotation of the shaft 3 swings the arm 15 from right to left, the gear segment 16 being maintained in engagement with said shaft 3 by the spring 21. The spring 19 maintains the knife 23 in engagement with the orange for removing the rind. As the knife 23 approaches the limit of its movement in this direction, the nger 33 engages the lever 32 and actuates said lever in a direction to shift the slidable bearing 14 against the tension of the spring 21 for disengaging the gear segment 16 from the worm shaft 3. Of course, movement of the arm 15 from right to left i'ncreases the tension of the spring 20 and when the gear 16 is disengaged from the worm shaft 3 said spring 20 returns the arm 15, and consequently the knife 23, to their starting positions. When the lever 32 shifts the slidable bearing 14 to disengage the gear segment from the shaft 3 the latch 34 engages in the recess 35 which is provided therefor in said slidable bearing for maintaining the gear 16 in disengaged position during the return movement of the knife. As the knife approaches its starting point, the finger 33 engages the end 37 of the lever 36 and actuates said lever in a manner to retract the latch 34, thus permitting the spring 21 to shift the bearing 14 for again engaging the gear 16 with the worm shaft 3.

As illustrated to advantage in Figure 1 of the drawings, the segmental gear 16 includes a comparatively high end tooth 40. This comparatively high tooth 40 engages with the worm shaft 3 at substantially the same time that the lever 32 shifts the bearing 14 for disengaging the segmental gear 16 from the worm shaft 3, thus assuring ample clearance for the teeth of said gear 16 during the return movement of the knife.

It is believed that the many advantages of an orange parer constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
