JOHN F. MCGUIRE AND ARCH H. HARRIS, OF AKRON, OHIO, ASSIGNORS OF ONE-THIRD TO CHARLES C. GOODRIOH, OF SAME PLACE.
KNIFE OR SHEARS SHARPENER.
SPECIFICATION forming part of Letters Patent No. 628,021, dated July 4, 1899. Application filed November 16, 1898. Serial No. 696 ,591. (No modeld To all whom it may concern.-
Be it known that we, JOHN F. MCGUIRE and ARCH H. HARRIS, citizens of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and nseful'lmprovement in Knife or Shears Sharpeners, of which the following is a specification.
Ourinvention has relation to improvements in devices for sharpening knives, shears, and scissors; and the object of our invention is to provide a neat and compact machine adapted to be readily secured to and removed from a table or shelf and by which an unskilled person may' accurately sharpen such articles; and its further object is to cause the stone to operate upon the blade with a compound sliding elliptic motion.
To the aforesaid purpose our invention consists in the peculiar and novel construction, arrangement, and combination of parts hereinafter described and then specifically pointed out in the claims, reference being had to the accompanying drawings,which form a part of this specification.
In the accompanying drawings, in which similar reference-numerals indicate like parts in the different views, Figure 1 is a front elevation, and Fig. 2 a side elevation, of our improved machine.
Referring to the figures, 1 is a vertical post forked or slotted at the top to form guides 2, provided with bosses 3 4 to form abutments for wheel-hubs and turned at a right angle at the bottom, where it is provided with a thumb-screw 5. The lower back part of this post is reinforced with a web 6 to afford strength. From the front of the post extends a horizontal arm '7, the outer end of which is turned upward parallel with the post 1 and ends in a peculiarly-formed head 8. Journaled on a wrist in the boss 3 is a spur-wheel 9, held by a cap-screw and provided with a handle 10, which meshes in a pinion 11, similarly retained on a short shaft 12, that runs in a bearing in the boss 4. On theopposite end of the shaft 12 is a disk-wheel 13, bearing a wrist provided with a clamp14, that grips the lower end of the stone 15, the upper end of the stone being held by a clamp 16 on a slide 17, that moves in the guides 2.
The head 8 has the upper face beveled at the proper degree to hold the blade of the shears or scissors to the stone, and this face has a number of grooves to rest the back of the knife in when its edge is subjected to the stone, a number being provided to adapt the machine to different widths of blades.
Having thus described'our invention, what we claim, and desire to secure byLetters Patent, is
1. In a knife and shears grinder the combination with a supporting-post, of a stone connected therewith having one end adapted to move reciprocally lengthwise, and the other to move in a circle, and mechanism such substantially as shown to impart motion to said stone, substantially as shown and described.
2. In a knife and shears grinder the combination with a stone having one end adapted to move reciprocally lengthwise and the other to move in a circle, of a supporting-head adjacent to said stone, and beveled to hold a shears-blade at a definite angle to said stone, substantially as shown and described.
3. In a knife and shears grinder the combi nation with a stone having one end adapted to move reciprocally lengthwise and the other to move in a circle, of a supporting-head ad 'jacent to said stone having grooves to receive ing a head adjacent to said stone beveled toward said stone and having in its upper face grooves parallel with the face of said stone,
substantially as shown and described.
In testimony that we claim the above we hereunto set our hands.
JOHN F. MCGUIRE.
AROH- H. HARRIS.
In presence of O. P. HUMPHREY, O. E. HUMPHREY.
