Application tiled June 1 5, 1909. Serial No. 502,258.
To all whom it may consent:
Be it known that I, FREDERICK P. OLDS, a citizen of the United States, resident of Berea,"county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Blade-Sharpening Machines, of which the following is a specification, the principle of the invention being herein explained andthe best mode in which I have contemplated applying that principle, so as to distinguish it from other inventions.
My invention relates to a new and improved form of blade-sharpening machine in which a longitudinally reciprocable abrading member shall 0 crate in conjuncurther has for its object, to provide a greatly simplified and extremely eflicient means for accomplishing the clamping of the blade and effecting the exercise of a variable and distributive pres sure upon the abrading member.
The said invention consists of means hereinafter fully described and particularly set forth in the claims.
The annexed drawing and the following description set forth in detail a certain means 1 embodying my invention, the described form,
however, being but one of various forms in which. the principle of the invention may be a died.
I in said annexed drawixigsz-Figure 1 is a top plan view of my invention, showing in dotted lines the blade-clamping device slid to the extreme lateral position. Fig. 2 is a side elevation showing the blade securely clamped and resting upon the stone. Fig. 3 is a cross section on line IIIIII of Fig. 2. Fig. 4 is a view of the clamping device proper, showing the blade inserted but'not clamped. Fig. 5 is a similar view showing the blade clamped in position for sharpenmg.
In the several views, similar reference letters refer to similar parts throughout.
Upon the sides of the base block A two side plates a a are secured in any approved manner, as by screws 0. a, to form a suitable bed frame. Upon each of these side plates near the upper inner edge, I provide two inwardly projecting flanges a a, forming a channel which shall serve as a guideway for the base flange b of the suitable carriage B,
adapted to hold the usual type of abrading member I). At one end of the bed frame on the side plates are projections shaped to form bearings a a for the crank shaft C having the arm 0 and handle 0'. Attached to tins-shaft in the usual manner is a connecting rod 0 pivoted to the carriage B and capable of imparting to it a reciprocable sliding motion when the crank-is turned. I further-provide upon the side plates a a and preferably a short distance from their longitudinal center twoupwardly extending standards b Z), which are likewise adapted to form bearings for an oscillatory rod 1). This rod extends a short distance beyond its bearing on both sides, for the purpose of permitting it to be slid laterally or in the direction of its axis; Fixedly secured to each of its ends is a lever arm d, supporting a handle dand adapted to oscillate said rod in any one of its positions in its bearings. The central portion of the rod I supply with a clamping member in the form of an elongated eccentric d". ()scillatorily mounted upon the rod over such elongated portion I provide a supplemental clamping member I) composed of two cars forming bearings on each side of the eccentric, and then bent to form two laterally extending and overlapping plates which are fastened together by set screws 6 0 This supplemental clamp- ,ing member-is of such a depth that the eccen tric on the rod will almost meet it, consequently a blade F'of normal thickness may readily be clamped against the inner faeethereof when the eccentric is turned against it. -The under side of this supplemental clamping member is secured to the frame by a spring G, for the purpose of normally holding it in a vertical position, and so make the insertion of a blade more easy.
The operation of my invention is as follows: When the eccentric d is turned away from the supplemental clamping member as shown in Fig. 4, there will be sufficient room for the insertion of the blade to be sharp,
ened, after which the turning of the rod D throws the eccentric against the under side combination of a suitable bed frame; an
mg means;
7 combination with an abrading'. member; means for reciprocating it longitudinally; a
suitable bed frame; a rod journaled on said 25 frame; a clampin member oscillatorily -mounted onvsaidro and. means comprising an eccentric upon said rod, adapted to clamp the blade against the clam ing' member when said rod is oscillated; and means for press-30 ing the blade .11 on'th'e abrading member.
4. In a bla e-sharpening machine, the combination with an abrading member and means for reciprocating; it longitudinally; of a suitable bed frame; an eccentric rod 35 blade-sharpening machine, the journaled on. said frame and lying across the .path of the abrading member; a clamping member oscillatorily mounted upon said Having fully described my invention, what I therefore claim and desire to secure by Letters Patent is 1. In a blade-sharpening machine, the
abrading member; blade-holding means; and means for effecting-relative reciprocation between said abra arid blade-holding means' said blade-hol ing means being laterally adjustable relatively to said abradsuitable bed frame; aerod journaled on said frame; a clampin member oscillatorily "mounted on said'ro and means comprising aneocentric'on said rod, adapted to clamp the bladeagainst said clamping member, the rod being slidable in the direction of its axis. 3. In a blade-sharpening machine, the
combination with an abrading member;
' means for reciprocating it longitudinally; a
rod; means for sliding said rod in the direction of its axis; and means for oscillating 40 the rod' to clamp, the blade Within said clampin member.
Signed by me, this 14th day of June, 1909.
