Specification of Letters Patent.
Patented NOV. 28, 1905.
Application filed February 28, 1905. Serial No. 246,892.
T0 all whom it may concern:
Be it known that 1, JOHN WALTER, a citizen of the United States, and a resident of that the sickle-bar can be readily introduced,
adjusted in the device, and locked in adjusted position or removed therefrom, and, further, to lprovide a construction whereby the sickleho der can be adjusted to any desired angle Y or to any bevel and can be vertically adjusted also moved forward and backward to impart the necessary movement to the knives over the stone.-
The invention consists in the novel construction and combination of the several parts, as willv be hereinafter fully set forth, and pointed out in the claims.
Reference is to be had to the accompanying drawin s, forming a part of this specification, in whic similar characters of reference indicate corresponding parts in all the'figures.
Figure 1 is a erspective view ofthe imroved sickle-ho der a plied to a grindstone. ig. 2 is a plan view 0 .the device and a portion of its sup orting-frame, Fig; 3 is avertical section t ough the device, taken pra.c' tically on the line 3 3 of 2 a verticalportion through a portion of the grindstoneframe, and a side elevation of a portion of the stone to which the device is applied. Fig. 4 is a verticalsection taken substantially on the line 44 of Fig. 2. Fig. 5 is a vertical transverse section taken substantially on the line 5 5 ofFig. 2, and Fig.6 is a detail perspective view of the adjustable end guide for the sickle-bar. Arepresents the frame of an ordinary grind-' stone, B the stone, and 0 represents bearings which are secured on the upper face of the side beams 10 of the frameat an end of saidbeams. Thebody member Dof the holder,
or the member which receives and carries the sickle-bar 11 and its'km'ves 12, ismade of any desired length and is intended to extend across the periphery of the stone B. In the construction of the said body a bar member 13 is employed, to the top of which a rearwardly-extending arm 14 is'secured, and below the arm 14 a clamp 15 is adjustably and removably mounted in the bar member 13, held in adjusted position by a set-screw 16, passed through the arm 14 and bar member 13 to an engagement with the insertedportion of the clamp. The head of this clamp is made to engage with the forward longitudinal edge of the sickle bar 11 and holds the sickle-bar from moving forward without interfering with the end or sliding movement of the sickle-bar, as is shown in Figs. 1 and 2.
One end of the sickle-bar 11 is loosely passed between upper and lower guide-fingers 17 and 18, which extend forward from one end portion'of the bar member 13, the opposing aces ofwhich fingers are more or less recessed to assist in preventing the forward movement of the sickle-bar 11.
. posite end of the bar member 13 of the body D at its back a longitudinal recess 19 is made, and in this recess 19 the shank 20 of an ad- At the opjustable guide (1 is located, the head of the said guide (1 being provided with a forwardlyextending pin 21, upon which pin an end portion of the sickle-bar 11 is made to rest. The guided is adjustably held in position by producing a longitudinal slot 22 in its shank 2( and passing a set-screw 23' through the slot and into the bar member of the body, as is shown in Fig.2, the said guide d being shown in detail in Fig. 6.
The arm 14, extendingfrom the bar member 13 of the body D, is adjustably attached to a" forwardlyextending fiat member 24 of a head Eby means of a bolt 25 or its equiva- I lent, so that the body D has horizontal ad- 'justment on said head, and the head E is swiveled or mounted to turn upon a cap F, said cap having a forwardly-extending cylindrical [member .26, which enters a correspondingly-shaped socket 27 in the said head, as is shown in Fig. 3, and the head E is held in adjusted position on the cap F by a set-screw 28, passing through the head to an engagement with the said member 26 of the cap. Thus it will be observed that the body D of the holder can be adjusted to any angle with 7 reference to the stone to grind any desired bevel at the cutting edges of the knives. The cap F is provided with downwardly-extending end lugs 29 in order that a standard G may have a pivotal or hinged connection with the cap, which standard is adapted to be connected with the frame A of the grindstone in a manner to be hereinafter described.
The pivotal or hinged connection between the standard G and the cap F is effected by providing the standard at its upper end with upwardly extending lugs 30, which are loosely passed up between the lugs 29 of the cap and by loosely passing a pin or bolt 31 through the lugs of the cap and the lugs of the standard, as is'shown in Fig. 4. This connection enables the body D of the holder to be operated vertically to and from the stone in order to remove a sickle-bar or place one in position.
A grooved projection 32 is formed upon the inner or forward face of the standard G, and the groove of the said projection receives the slotted shank 33 of a pivotal connecting member H, which member is provided with base-pins 34, adapted to be mounted in the bearings C on the frame A of the grindstone. An adjustable connection is effected between the hin e connecting member H and the standard G by means of a bolt 35, passed through the standard and through the slot in the shank 33, as is illustrated in Figs. 3 and 4. The pivotal connecting memberHis preferably made of stout wire or bar metal bent to the shape desired.
It will be observed that by reason of the pivotal connection between the standard G and the frame A of the grindstone and the pivotal connection between the cap F and the standard the body D, carrying the sickle-bar 11, can be moved backward and forward to bring the cutting edges of the knives their full length in reciprocating engagement with the grindstone. It will also be observed that by reason of the vertical adjustment between the pivotal connecting member H and the standard G the device can be lengthened or shortened to accommodate it to different sizes of grindstones. The sickle-bar 11 is firmly held in position at the body D while a knife is being ground by securing a horizontal forwardly-extending rest-arm 37 to the bar member 13 of the said body D, against the under face of which arm a knife 12 of the sickle-bar 11 has bearing, and pivoting a yokeclamp 38 to the outer end of the said arm, one member of which extends above the arm and the other below it, the under member being somewhat upwardly curved, the knife just referred to occupying a position below the lower member of the clamp and the under face of the rest-arm, as is shown is Fig. 3. The knife which is thus clamped is the one adjacent to the knife being acted upon by the stone.
A lever 39 is employed in connection with the clamping-yoke 38 to carry the lower member of the yoke upward to hold a knife firmly against the rest-arm 37 when another knife is being sharpened and to permit said lower member of the yoke-clamp to drop when the sickle-bar is to be shifted, introduced, or removed.
The handle end of the lever 39 extends rearwardly over the bar member 13 of the body D, and its opposite or forward end is pivotally attached to the end portion of the upper member of the clamping-yoke 38, as is shown at 40 in the drawings, and at the pivotal end of the lever 39 a downwardly-extending cam-finger 41 is attached to or is made integral with the lever, which finger when. the handle end of the lever is pressed downward has locking bearing upon the upper face of the rest-arm 37 and at such time raises the upper member of the yoke-clamp, thereby carrying the lower member also upward to tight locking engagement with the knife; but when the handle of the lever 39 is carried upward and forward the cam-finger 41 will be out of engagement with the restarm 37, whereupon the lower member of the clamping -yoke will through gravity drop down and free the knife with which it ongaged.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In sickle-holding attachments to grindstones, a body member, guide or check devices for the sickle-bar carried by the said body member, a rest-arm also carried by the said body member, a clamping-yoke pivoted on the rest-arm and extending above and below said arm, and a lever for operating the clamping-yoke.
