application filed April 27, 1911. Serial No. 623,799.

To all whom it may concern:

Be it known that I, Moirrnonn QUiRY, a citizen of the United States, residing at h lorganfield, in the county of Union and State of Kentucky, have invented a new and useful Disk-Sharpener, of which the following is a specification.

The device forming the subject, matter of this application, is a machine adapted to be employed for sharpening the disks of agricultural implements.

It is the "object of the present invention to provide novel means for actuating the grinding rolls, and to provide novel means for adjusting the position of the disk with respect to the grinding rolls.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made Within the scope of what is claimed without departing from the spirit of the invention.

In the .drawingsfiignre 1 shows the invention'in side elevation; Fig. 2 is an end. elevation, parts being removed; Fig. 3 is a horizontal section on the line AB of Fig. 2; Fig; 4 is an end elevation, supplemental to the showing of Fig. 2; Fig. 5 is a plan of. the guide plate; Fig. 16 is a side elevation may likewise be supplied with outstanding of the upper grinding roll; Fig. 7 is a side elevation of the lower grinding roll; and Fig. 8 is an elevation of a' modified form of disk-holding means.

In carrying out the invention there is provided as a primary element, a base 1.

provided, if desired, along its sides, with reinforcing plates 2, and provided along its forward end with a reinforcing plate 3. Secured to the upper face of the base 1, is an arched support 4, having, as seen in Fig. v3, along. its inner faces, outstanding ribs 5. adapted to form slidable mountings for an upper boxing 6, and a lower boxing 7.

Applied to the rear face of the support 4, is

a guide plate'S, seen in clearest detail in Fig. 5.. The guide plate 8 is equipped with an upright slot 9, and if desired, the guide plate ears 10, adapted to mate with similar ears is the lower grinding roll 12. The forward ends of the rolls 11 and 12 protrude beyond the forward face of the support at, the protruding ends of the rolls 11 and 12, be ing tapered, as shown at 14:, so as to receive. properly between them, the edge of the disk which is to be sharpened. As clearly appearing in Figs. 6 and 7 the grinding rolls l1 and 12 are c-ircumferentially grooved, as shown at 15; so as to engage in the slot 1) of the guide plate 8. The shaft 16 of the lower grinding roll 12 is of sufficient length to extend rearwardly, for rotation in a basesupported bearing 17. Upon the shaft 18 of theupper grinding roll 11, there is so cured a pinion 19, meshing into a pinion 20, secured to the shaft- 16 of the lower grinding roll 12. At this point it may be noted profitably, that the rolls 11 and 12 are not parallel, the upper roll 11 being inclined slightly with respectto the horizontal, so that the operative end of the'said upper grinding roll 11 may engage properly with the inner, concaved. face of the disk which is to be sharpened. The shaft 16 of the lower grinding roll 12 protrudes rearwardly through the boxing 17. Upon the protruding end of the shaft 16, there is mounted a pinion 21, meshing into another, smaller pinion 22, secured upon the shaft 23, journaled for rotation in bearings 24, carried by the base 1, to one side of the support i.

I The rear end of the shaft 23 is received for rotation in a brackct24, secured to the rear end face of the base 1. Upon the shaft 23, between the bearings 24, thereare collars 25, holding the shaft 23 against longitudinal movement. a Thatend of the shaft 23 which protrudes beyond the bracket 24-", may be supplied with a belt wheel 26:

The construction above described, presupposes that the shaft 23 is to be power-driven. Frequently, it: may be desirable to operate the machine by hand, and under such circumstances, the construction may readily be altered to effect this result, this alteration threaded into a boss28 formed in-the upper portion of the guide 4, the lower end of the screw 27 engaging with the upper boxing 26, whereby the upper grinding roll 11 is carried. For the manipulation of the screw 27, the same may be provided at its upper end with a hand wheel 29, or with any other element adapted to a like end.

Carried by the base 1, is a forwardly outstanding arm 30, preferably sustained by diverging braces 31, united at one end with the arm 30, and at their other ends, united with the base 1. Mounted for sliding move ment upon the arm 30, longitudinally of the same, is a head 32, the head 32 being held in adjusted positions upon the arm 30, by means of a set screw 33 or the like, threaded into the head.

Mounted for vertical adjustment in the head 32, is an upright standard 34, to the upper end of which is pivoted as shown at 35, a support 36, comprising spaced arms, united at their outer ends. Held for sliding movement between the arms of the support 36, is a holder 37, provided in its upper face, with an outstanding stud 38, adapted to extend through the opening in the center of the disk which is to be sharpened. This stud 38 may be of any desired construction, depending upon the nature of the disk which is to be handled in the machine.

In order to secure an adjustment of the.

holder 37, longitudinally of the support 36, a screw 39, provided with a suitable operat-ing wheel 40, is threaded into the end of v the support 36. and into the holder 37. An, adjusting bar 41 is provided, the upper end of which is pivoted, as shown at 42, to the support 36, adjacent the free, rear end of the support. The adjusting bar 41 is supplied with a longitudinally extended slot'43, through which extends a set screw 44, or other clamping device, the set screw 44 engaging the arm 30.

In Fig. 8 of the drawings, a slight modification is shown. Referring to Fig. 8, the

holder is denoted by the numeral 45, the

same having an outstanding arm 46, upon which is pivoted as shown at 47. a segment 48, having an arcuate slot 49, in which is disposed a clamping element 50, adapted'to enter the arm 46, to hold the segment 48 in various positions of adjustment. The segment 48 carries at its outer end, a stud 51, fidgpted to be engaged in the opening in the to be sharpened, as will be readily un-- 'derstood.

The operation of the device is as follows: The stud 38 is engaged in the opening of the disk which is to be sharpened, and the standard 34 is adjusted vertically, so as to position the disk for engagement between the tapered ends 14 of the grinding rolls 11 and 12. By manipulating the set screw 33, the head 32 is slid to and fro upon the arm 30, until the edge of the disk is properly positioned between the grinding rolls 11 and 12. The holder 37 may likewise be adjusted longitudinally of the support 36, by manipulating the screw 39. The proper angle with respect to the horizontal, is secured for the disk which is to be sharpened, by loosening the adjusting screw 44, and by elevating and lowering the adjusting bar-41, until the support 36 acquires the proper angle with respect to the horizontal.

From the foregoing, it will be seen that a variety of adjustments are provided, whereby the disk which is to be sharpened may be properly positioned with respect to .the grinding rolls 11 and 12.

hen the belt wheel 26 is rotated, rotation will be imparted to the shaft 23, the pinion 22 of which will mesh into the pinion 21, the latter pinion imparting a rotation to the lower grinding roll 12, the pinion 20 of which, meshing into the pinion 19, will impart a rotation to the upper grinding roll 11.

Referring to that form of the invention which is shown in Fig. 8, it will be seen that by loosening the clamping member 50, the segment 48 may be tilted laterally, thuspermitting the disk which .is carried by the stud 51 to assume different angles with respect to thegrinding rolls 11 and 12, whereby the said rolls may be made to engage properly,

with both the inner and outer faces of fthe disk which is to be sharpened.

Having thus described the invention, what is claimed is 1. A device of the class described comprising a supporting arm; a standard secured to the arm for adjustment both longitudinally of the arm and transversely of the arm; a support pivoted to the standard; an adjustmg member pivoted to the support; means for adj ustably uniting said member with the arm; a disk-holder mounted for sliding movement in the support; means for maintaining the holder in adjusted position, longitudinally of the support; and grinding mechanism disposed in operative relation with respect to the holder.
