SICKLZEl-BLADE. HOLDER;
Application field March 13, 1922. Serial No. 543,352.
T 0 all whom. it may concern Be it known that I, Aiv'ronn J. Armored, a. citizen of the United States, residingat ()rient, in the county of Faulk andStzite of South Dakota, have invented certain new and useful Improvements in Sickle-Blade Holders, of which the following is a specification, reference being had to the accompanying drawings.
Itis the purpose o-f'the present. invention to provide an improved device of this character, for holding blades while sharpening them on a grind stone.
Another purpose is the provision of a holder including a supporting frame to straddle the grind stone and to be mounted on the frame of the grind stone, and including a movable hanger universally con nected to the supporting frame, to permit the blade to be shifted to different positions.
relatively to the grind stone, whereby the teeth oft-he sickle blade may be sharpened;
each on one side. and then eachon its op-' posite side, that is to say beginning at one end of the blade, until the opposite end of the blade is reach.ed, and then shifting the blade in an opposite tilted ginning at the other end. 7
Still another purpose is the provision of a holder of this kind having means. whereby the grinding and sharpening of sickle blades may be greatly facilitated, for example the hanger may be adjusted at different positions, tilted on. one side and then the other, tilted rearwardly and downwardly, or for-f wardly and downwardly. there being yieldable means connecting the blade holding clamps and the hanger, so as to relieve the weight of the blade on the operator.
It is well known that sickle blades are more or less heavy, and it is very diflicult to hold the blade in ones hand, and properly sharpen each tooth, and at the same time support the projecting end of the blade. In
other words the weight of the blade renders the manual holding of the blade very the some, which will prevent the teeth of the blade from being sharpened properly.
lVhile the design and construction at present illustrated and set forth are deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible of changes, and the right to these changes is claimed, proposition, and be vided theyrare comprehended within the scope of what is claimed. The invention comprises further features and combinations of parts, as will be hereinafter setforth, shown in the drawings and claimed. 1
In the drawings Figure 1 is a View in perspective. showing the improved holder as applied toa frame of a grind stone, with a sickle blade attached; J
Figure 2 is an enlarged view in elevation of the hanger, showing the same in a tilted position; i
Figure 3 is an enlarged detail view of one of the clamps for the blade; and i I Figure 4 is a sectional view of the blade showing the clamp applied.
Referring to the drawings, 1 designates the side supports of the grind stone frame, and 2 denotes the arms of the supporting frame 3 for the holder. The arms 2 of the supporting framestraddle the grind stone, and their right angle extensions 4 (which are shaped to conform'tothe contour of the side supports 1 of the grind stone frame), are (secured to the supports 1 by means of the-clamps 5. The supporting frame 3 has an upstanding post 6, on which a. sleeve 7 is secured by a set bolt 8. An arm 9 projects from the sleeve 7, and. straddling the arm is a U-shaped casting 10, which is provided, with an upstanding projection 11. The lower extremities of the sides of the U shaped casting terminate in opposite sockets 12, which receive a spherical member 13,.for the purpose of supporting the hanger l4 universally from the casting.
seat of the grind -stone frame, is a guide bracket 18, provided with a guide slot 19. The guide slot 19 receives the projection 11.
,to assist in holding thehanger in different positions, whenshifted, for the purpose of A suitable bolt 15 passes through the sides-of the castthe hanger.-
ator may shift the hanger as different positions.
A rod 21 is mounted to move through the tubular bearing 16, and depending from the ends of the rod 21 are springs 22, which are in turn connected to. the chains 23. Holding levers 24 of sickle blade clamps 25 are connected to suitable hooks of the chains 23, so that the Weightof the sickle blade 26 (which is engaged with the two clamps 25) will cause the levers to'bear upon and hold the blade 26 in the clamps. The more the bladeis moved downwardly, the tighter. the clamping levers 24 engage and hold the blade. Also the heavier the blade, the tighter the clamping levers will secure it. in the'clamps. j
Obviously the rod 21 can be shifted through the tubular bearing, so as to permit the operator to begin sharpeningthe teeth of the sickle blade at one end and finish at the opposite end. Also either end of the blade can be tilted downwardly, not only by shifting the hanger, but by stretching the springs. l/Vhen the rod 21 assumes a central position relatively to the bearing 14, the sickle blade may be depressed substantially on a level plane with relation to; the grind stone, or it may be tilted. By .a careful examination of the drawingsit can be-well understood how the blade andthe hanger can shifted in various positions, either transversely of the operator, in tilted p051 tions, or in a direction away from the operator.
The invention having been set forth, what a hanger mounted for universal movement on said supporting frame and prov ded with a guide slot operatively receiving said supporting frame, to guide the hanger whenadj usted and to set the same in position after being adjusted, and means for adjustably, operatively suspending a sickle blade from 2. In a sickle blade holder, a base frame, a supporting frame mounted u gon the base frame and provided with a 'gu i"d projection, ahanger mounted for universal movement on said supporting frame and having guide and holding connections with said projeclion, a member adjustably mounted on the hanger for transverse movement thereof, and means for operative-1y suspending a sickle blade from said member.
3. In asickle blade holder, a base, asupporting-frame thereon and provided with an arm, a hanger mounted for universal movement on said arm and provided with guide connections with said arm for guiding the hanger when shifted, and setting the same after being shifted, a member connected to the hanger for transverse shifting movement, and means for operatively suspending the sickle blade from the member.
4; In-a sickle blade holder, a base, a supporting frame thereon provided with a projecting arm, a clamp mounted on the frame and provided with a projection, a hanger mounted for universal I movement on the clamp and provided with a guide slot receiving said projection, for guiding the hall".
gerwhen shifted universally, and setting the same-afterbeing shifted, a membeii mounted for adjustable sliding connections on the hanger, and means for operatively suspending a sickle blade from said member.
In a sickle blade holder, at base, a supporting frame thereon provided with a projetting arm, a clamp mounted on the frame and provided with aprojection, a hanger mounted for universal movement 011 the clamp and provided with a guide slot receiving said projection, for guiding the hanger when shifted universally, and setting the same after being shifted, a member mounted for adjustable sliding connections onthe hanger, and means for operativelysuspending a sickle blade from said member, said suspending means including clamps for clamping the sickle sharpened.
In testimony whereof I hereunto aflix my signature.
