SOULIOS GRINDING WHEEL DRESSER DEVICE 2 Sheets-Sheet 2 Filed Nov. 7, 1962 United States Patent 3,137,288 GRINDING WHEEL DRESSER DEVICE Chris Soulios, Wakefield, Mass. (197 Chelsea St., Everett 49, Mass.) Filed Nov. 7, 1962, Ser. No. 236,039 2 Claims. (Cl. 125-11) This invention relates to a machine to dress grinding wheels and the like.
One object of my invention is to provide such a machine having a dresser member that can be adjusted to the angle desired by moving a protractor member, that is an integral part of my machine to any desired position.
Another object is to provide such a machine having an actuator with a shaft that carries a dresser member which the shaft actuates, which actuator can be moved to various positions along with said dresser member by a simple movement.
Still another object is to provide such an actuator with a mounting member whereby control of the movement of said shaft both longitudinally and rotatably can be attained by mechanism connected with the mounting member.
A further object is to provide a radial dressing attachment that can be carried by said shaft and which enables a radial dressing operation by rotation of the shaft when occasion requires.
The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative arrangement of parts such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and therefore, I am not to be limited to the construction disclosed by the drawings nor to the particular parts described in the specification; but am entitled to all such changes therefrom as fall within the scope of my claims.
In the drawings:
FIG. 1 is a side elevational view of my grinding wheel dressing machine.
FIG. 2 is a rear elevational view thereof.
FIG. 3 is a sectional view taken on the line 33 of FIG. 1.
FIG. 4 is a sectional view taken on the line 44 of FIG. 1.
FIG. 5 is a sectional view taken on the line 5-5 of FIG. 1.
FIG. 6 is a diagrammatic view showing the dresser member of my device in position to dress a grinding wheel, the latter being indicated by broken lines, some of the dash lines indicating the different positions of the parts during a dressing operation, while other of the dash lines indicate the position of the parts in another position.
FIG. 7 is a side elevational view of a radial dressing attachment shown attached to a shaft to accomplish radial dressing.
FIG. 8 is an end elevational view of the radial dressing attachment shown in FIG. 7.
As illustrated my grinding wheel dresser device has a main support 10 shown in the form of a right angle having a vertical portion 12 that has a reinforcing portion 13. Movably supported by said support 10 is a holder 14 having a mounting member or portion 16 which is of oblong shape as shown through which an elongate hole 18 extends its full length. Said mounting 16 has two countersunk holes 20 at opposite ends and it also has bushings 22 for a shaft 48 later described.
Said holder 14 preferably includes an integral, positioning portion 24 which may serve as a protractor of semi-circular shape having a central indicator point 25. Said protractor portion 24 has certain indicia I marked thereon to indicate the degree at which said actuator is 3,137,288 Patented June 16, 1964 set and thus the degree at which a grinding wheel 100 later described, will be dressed. On said support portion 12 a location line L is marked whichindicates a zero point as shown in FIG. 1.
A hub 26 is formed on said positioning portion 24 having a hole 28 therethrough to receive a pivot pin 30 on which said holder may rotatably move relative to said main support portion 12. I show a washer 32 between the head of said pivot pin 30 and said hub 26. Said pivot pin 30 has alocking knob 34 at one end which serves to hold said holder 14 in any predetermined position. A lower boss 36 on said member .24 has a hole 38 extending through it.
On said support vertical portion 12 I provide a number of positioning recesses 40 which extend along an are if a line were drawn from one to the other. Set in said positioning portion 24 is a locking member 42. which any one of recesses 40 will receive. This locking member 42 is shown as a ball bearing against which a compression spring 44 bears that is retained in a retainer housing 46 so that said locking member 42 will be held firmly in one or the other of said recesses 40 depending upon the angle at which said actuator is to be positioned.
An actuating shaft 48 extends through said hole 18 and is longitudinally moved therein during operation thereof. It has retainer means shown as a retaining collar 50 thereon against which one end of a compression spring 52 bears while the other end bears against said mounting 16. At one end of said shaft 48 is a threaded hole 54 that receives a screw 58 that enters a knob 56 to thereby hold said knob to said shaft. At another end of said shaft 48 is a hole 60 extending diagonally therethrough to receive a dresser member having a holder 61 on which a diamond nib 62 is set, as shown. At the end of shaft 48 is a threaded hole 64 in which a screw 66 is received to reach and frictionally hold said holder 61 in position.
Said mounting 16 has an elongate slot 68 therein which serves to limit the longitudinal movement of said shaft 48 in said hole 18 by means of a screw-threaded stud or sliding guide 70 extending through said slot 68 into a threaded hole 72 in shaft 48. A rotary guide member shown as a locking screw 74 is screw-threadedly connected to said mounting 16 and it can enter a narrow, circular groove 76 in shaft 48 in which event said shaft is held against longitudinal movement in said hole 18 as later explained. There is also a flat recessed portion 78 in shaft 48 into which said locking screw 74 may enter but not far enough to interfere with the longitudinal movement of said shaft 48 unless otherwise desired.
When my device is used to dress a grinding wheel radially, I provide an angular, radial attachment 80 that may be swung on a radius by rotating the shaft 48. It has an attaching angle member 82 having an opening 84 therethrough to receive shaft 48. A slit 86 at the outside end communicates with said opening 84 and a screw 88 enters a screw-threaded hole 89 and extends through said slit 86, which firmly holds the shaft 48 in opening 84 when screw 88 is tightened.
Said angular attachment 80 has an angular holder member 90 extending at a right anglefrom angle member 82 and having a hole 92 therethrough to receive said holder 61. One end portion of holder member 90 is split as at 94 and a binding screw 96 extends into a threaded hole 98 and across said split 94 to thereby firmly hold G it serves as a guide as said shaft 48 is rotated to dress a grinding wheel radially.
To determine the angle at which the diamond point 62 will perform its dressing operation, said locking knob 34 is loosened and said holder 14 is rotated on pivot pin 30 untilthe holder is in a position to present the diamond point at a predetermined angle to the surface to be ground on a well-known grinding wheel 100. The latter is shown mounted on a spindle 102 set in a bearing 104 as illus tratedin said FIG. 6.
Tightening of said locking knob 14 in any desired position.
What I claim is: a
1. A grinding wheel dressing device comprising a main support, a holder, means adjustably connecting said holder to said support, said holder embodying a mounting member having a hole therethrough, a shaft movably extending through said hole, having a circular, peripheral groove therein to receive a rotary guide member, said shaft being adapted to support a grinding wheel dresser member, said mounting member having a slot therein, a sliding guide member slidable in said slot and attached to said shaft whereby the limits of longitudinal movement of said shaft in said mounting member is defined by said slot.
2. A grinding wheel dressing device comprising a main support, a holder, means adjustably connecting said holder to said support, said holder embodying a mounting mem- 34 holds the actuator her having an elongate hole therethrough, a shaft rotatably extending through said hole having a circular, peripheral groove therein, a rotary guide member connected to said mounting member and entering said groove, an angular attachment to support a grinding wheel dresser member attached to said shaft and having a slit portion at one end of each angular portion and each said end having a hole adjacent a said slit portion, said shaft extending into one of said holes, and a screw extending laterally through one of said slit portions to hold said shaft firmly in said latter hole, and another screw extending laterally through the other said slit portion, and a dresser member holder extending into the other said hole and held in position by said other screw.
