Specification of Letters Patent No.

'o all 'whom it may concern:

Be it known that GUiv H. HUBBARD, deceased, late of Shelburne Falls, in the county o-f Franklin and State of Massachusetts, did invent certain, new and useful Improvements in Apple-Slicers, and it is hereby declared t-hat the following, in connection with the accompanying drawings, which constitute a part of this specification, is a full and exact description thereof, as attached to a paring-machine constructed vunder Letters Patent issued to S. N. Maxam, April 10, 1855.

The machine is secured to the table by means of the clamp, A, and to this is attached the st-andard, B, by means of the strong joint at B, which permits the careening of the machine both right and left.

E, is the driving wheel, motion being given by means of the crank to all the parts. Upon the face of the driving wheel, E, is an inclined scroll, F, upon which one end of the rack bar, G, slides; this rack bar connects with, and gives motion to, the loop gear, H, which supports and guides the spring rod, I, upon which is affixed the paring knife, J.

The machine being careened to the right as shown in red outline in Fig. l, as the operator stands in position to seize the crank with his right hand, an apple is placed upon the fork, K, when, by rotation of the crank, the driving wheel, E, gives motion to the pinion E and thence to the fork and apple, while the scroll, F, acting through the rack bar, G, upon the loop gear, H, the paring knife, J, is thereby passed, during t-he rotation of the apple, from its base around to its outer end, and eifectually pares the apple, when the outer circuit of the scroll, F, having passed the end of the rack bar, G,-the coiled spring, S, attached to the outer end of the rack bar, contracts, and returns the rack bar, loop gear, spring rod and paring knife, to their original positions in readiness to repeat the operation of paring. The apple thus pared is in readiness for the action of the slicer, which is constructed and arranged as follows To the standard, B, is hinged at N, a strong arm of iron, N, sustaining the cross gage head,

I), to which is aflixed the curved knife, O, 1n such position that the edge thereof alines near the axis of the fork, K, and swinging upon the hinge at N', in a plane nearly parallel to said axis. A tripping post, M, is attached to the clamp, A, which, on careening the `machine to the left, comes in contact with the pin, L, passing through the shaft of the loop gear, H, and causes the partial rotation of the loop gear, H, and thereby withdraws the end ofthe rack bar, G, from the scroll, F, thus permitting the backward rotation of the crank and driving wheel, together with the fork and apple. The machine being now careened to the left, as described, and the pared apple remaining upon the fork, the arm, N, with the slicing knife, O attached, is swung by the left hand and the knife pressed lightly against the apple, which is thereby cut, during its backward rotation, into one continuous slice or ribbon, leaving only the core in cylindrical form upon the fork. The careening of the machine perfectly accomplishes the separation of the slices from the parings by depositing each in somewhat widely separated positions or receptacles, while the parabolic curvature of the knife produces such a formation of slices that they do not pack closely together while drying, and yet are not in the least objectionable for immediate cooking.

The arm, N, may-be so hinged to the standard as to swing perpendicular to the axis o-f the fork, if desired to commence the slicing at the equator of the apple, yet the present arrangement is deemed preferable. The detaching of the rack bar from the scroll, and an equiva-lent detaching of the feed gear, in other machines to which the slicer may be attached, I have accomplished without the tripping-post, M, by the use of the lug or cam upon the hinge-frame of the arm, N, as shown at R, Fig. 2, but prefer the tripping post as described.

I do not claim the cutting of apples into continuous slices, or ribbons; nor any formation of slices to prevent their close packing while drying. Neither do I claim, nor conne myself to, any particular curvature of the knife, O, nor the application of the arm, N, and knife, O, to the particular machine represented, several dilierent ones being equally appropriate therefor, but

What I do claim as my invention and de- 5 sire to secure by Letters Patent, is

The arrangement of the machine with its paring and slicing knives n such a manner as to careen upon the joint B in the manner and for the purpose substantially as set forth.
