March 14, 1961 N. H. WILLIAMS FLAYING IMPLEMENT 2 Sheets-Sheet 1 Filed Oct. 28, 1958 INVENTOR ATTORNEYYS March 14, 1961 N. H. WILLIAMS 2,974,413
FLAYING IMPLEMENT Filed Oct. 28, 1958 2 Sheets-Sheet 2 All INVENTOR BY W ATTORNEYS United States FLAYING IMPLEMENT Newton Halsted Williams, Newtown, Conn., assignor to Richard W. Logan, Madison, Conn.
Filed Oct. 28, 1958, Ser. No. 770,177 7 Claims. (Cl. 30--219) is exposed so that it may be used for the intended purpose. The blades are commonly rotatable about a common pivot or axis and are of substantially the same diameter, and the frame or casing is tubular or hollow so as to receive a rotating shaft so connected to the blades as to effect their oscillation.
' One object of my invention is to provide an apparatus of the character described which may be economically made and of relatively simple construction and at the same time eflicient in operation and capable of long use.
Still another object of the invention is to provide novel means for effecting the oscillation of the blades from a rotating shaft. I
A still further object of the invention is to provide a connection between the blades and the oscillating mechanism which may be adjustable so that different portions of the blades may be employed in use, thus rendering the tool capable of longer use without the necessity of sharpening the teeth thereof.
Still another object of the invention is to provide a flaying implement of the character described wherein the blades will operate with as little friction as possible and at the same time the teeth of the blades will be urged into contact with eachother so as to cooperate efliciently m use.
A still further object of the invention is to lengthen the life of theimplement by providing teeth over the entire periphery of the blades and connect the latter adjustably to oscillating yoke members so that the blades may be 'set at different positions relatively to the casing or frame and different sections of the teeth employed in use.
To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.
In the accompanying drawings:
Fig. 1 is a plan view of a flaying instrument embodying my invention;
Fig. 2 is an enlarged sectional view Fig. 1;
Fig. 3 is a top plan view of the operating mechanism with the upper cheek of the casing removed to show the interior parts;
Fig. 4 is a sectional view of one of the disklike blades;
Fig. 5 is a view in plan and elevation of a corrugated spring employed for urging the blades into contact;
Fig. 6 is a perspective view of theactuating yoke member for one of the blades; and
Fig. 7 is a similar view of the actuating yoke member for the other blade.
on line 2-2 of aren't O i Patented Mar. 14, 1961 shaft 16 having thereon a pair of oppositely disposed eccentrics 17 and 18.
The cheek member 10 is removably secured to the member 11 by means of the screw 20 having an enlarged head 21 at one end and the other end of the screw being threaded into a nut 22 secured to the cheek member 11 by the pin 23. Aligning pins 24 (one of which is shown) are secured to the socket 12 and may be received in openings 25 of the cheek member 10.
Secured to the cheek member 11 by the pin 23 is a hollow pivot pin 26 which surrounds the screw 20 and which is provided with a flange 27. A flange 28 is secured to the cheek member 10 by a pin 29 and between these two flanges cooperating blades 30 and 31 are rotatably mounted upon the pivot member 26. These disklike blades are of circular form and are provided with peripheral teeth 33 which, as shown, extend around the entire periphery of the blades.
Between the flanges 27 and 28 and the adjacent blades are provided actuating yoke members 34 and 35 shown in Figs. 6 and 7. The member 34 is adjacent the blade 30 and is provided with a flat body portion having an opening 36 receiving the pivot member 26 so that this member is oscillatably or rotatably mounted about the pivot of the blades. The member extends rearwardly and is bent outwardly, as shown at 37, and at its rear end provided with downwardly extending spaced arms 38 between which is snugly positioned the eccentric 18. At an intermediate portion of this member is provided a stud or pin 40 adapted to be received in one of a pair of openings 41 in the associated blade so as to connect this actuating member nonrotatably to the blade.
The actuating member 35 is made similarly to the member 34 and is provided with an opening 42 which receives the pivot pin 26 and is bent outwardly, as shown at 43, and provided with spaced inwardly turned arms 44 between which the eccentric 17 is snugly received. The arms 44 may be joined by'an integrally formed bar 45 so as to strengthen the construction. The intermediate portion of this member also is provided with a stud 01' pin 46 to be received in an opening 41 in the blade As shown more particularly in Figs. 2 and 5, a circular corrugated spring 47 is disposed between the flange 28 and the actuating member 34, which spring urges the adjacent blade into contact with the cooperating blade so that the teeth of the blades will properly cooperate. In order that the teeth of the blades be in contact and at the same time provide for a minimum amount of friction between the blades when the tool is in use, it will be noted from Fig. 4 of the drawing that the inner surface 48 of each blade is slightly dished or concave so that, while the blades will be in contact over their peripheral portions, the intermediate portions will be slightly out of contact and thus friction will be reduced. Each of the blades is provided with a central opening 49 to receive the pivot member 26.
As previously stated, the handle member 14 is hollow and within this handle is a sleeve 56 secured to the shaft 16, which sleeve is provided with a polygonal opening 51 to receive a similarly shaped shaft 52 carried by a flexible shaft 53. The latter may be surrounded by a bushing 54 having an annular channel 55 receiving a pin 56 carried by one end of a spring 57 secured in a recess 3 58 in the handle. This pin serves to detachably secure the flexible shaft to the handle of the tool.
The provision of a pair of openings 41 in each of the blades permits the blades to be turned through an angle of 180 degrees and connected to the yokes 34 and 35 so that the opposite edges thereof will be disposed outwardly for use. Thus, when the teeth of the blades become dull when the blades are in one position, they may be turned through an angle of 180 degrees and the teeth on the other side of the blades employed.
While I have shown and described a preferred embodiment of my invention, it will be understood that it is not to be limited to all of the details shown, but is capable of modification and variation within the spirit of the invention and within the scope of the claims.
What I claim is:
1. A fiaying tool having a frame, a pair of superposed disklike blades oscillatably mounted in the frame upon a common pivot, said blades having peripheral cooperating teeth, a pair of actuating members'each pivoted on said pivot, means connecting each of the actuating members to one of the blades at a plurality of'points eccentric to its pivot means to oscillate said actuating members to effect oscillation of the blades in opposite directions, and said blades being of circular shape and the teeth extending over substantially the entire circumference thereof,
