GRINDING WHEEL DRESSER Filed'Dec. 4, 1946 2 Sheets-Sheet 1 z 2 d I 28a D Inventor Adaiph 8mm? meys Uct. 26, v A. SMITH 9 9 GRINDING WHEEL nmassxsm 7 Filed Dec. 4, 1946 *z'sneets-sheet z Inventor Adam Patented Oct. 26, 1948 rarely-*1 oe-Free 2 Claims.

. ,1 I 'I he present invention relates to new and-useful improvements ina-pparatus f-or dressing"grinding w-heels and" the invention has 'for its primary obj eot to providean attabhmentwhich maybe'easily and quickly mountedninwpo'sitiorrito a part of the grinding wheel and includinga rotating dressing wheelfor.., the peripheral-:dge of the grin'ding wheel.

A further object of the invention is to provide means for adjusting the dressing wheel transversely of the grinding wheel and forwardly and rearwardly relative to the peripheral edge thereof.

A still further object is to provide a grinding Wheel dressing attachment of simple and practical construction, which is efficient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the detachable bed for the dressing Wheel.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a top plan view showing the device attached to the guard of a grinding wheel and with parts thereof broken away and shown sections.

Figure 4 is a side elevational view.

Figure 5 is a sectional view taken on the line 55 of Figure 4.

Figure 6 is a sectional View taken on the line 6-6 of Figure 5, and

Figure 7 is a perspective view of a modified table rest.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention the numeral 5 designates an attaching bracket generally which includes an arm 6 attached at one end to the side of'a grinding wheel guard I by means of a bolt 8, the grinding wheel being shown at 9 and which is of a conventional power operated type.

An upstanding support I0 is formed with a longitudinally extended slot I I for adjustably connecting the lower end of the support to the outer end of the arm 6 by a bolt and nut I2 and the upper end of the support I0 is also provided with a bolt and nut I3 for pivotally attaching a table rest I l 'thereto' by" means "of an apertured "lug'i 5 on the 'under's'ideof'the-table rest.

*A table I 6 is formedatits'side'edges wti-h down- '-wardlyeirtendingflanges I lwhich areclampedto the side edges "of 'the table re'st I 4 by conventional set screws "I B te-adjust the table forwardlwan'd rearwardly on-the'table rest I l'.

' Phe table l 6- is aisd'formed at its Side-with upwardly extending flanges [9 having horizontal slots formed therein and in which a transverse rod 2I has its ends positioned for adjustment longitudinally in the slots. The rod ZI is secured against endwise movement by nuts 22 threaded on the outer ends of the rod and positioned against the outside of the flanges I9.

Front and rear adjusting

screws

23 and 24 are threaded through the ends of the flanges I9 with their inner ends positioned against opposite sides of the rod 2| to secure the rod in adjusted position in the slots 20.

The upper edges of the flanges I9 are formed with scales 25 along which pointers 26 carried by the rod 2| are arranged to travel to indicate the position of adjustment of the rod.

A handle 2'! is pivotally and slidably mounted adjacent its front end of the rod 2| for vertical pivotal movement of the front end of the handle and for transverse sliding movement of the handle on the rod. A dressing wheel 28 is journaled on transverse shaft 28a at the bifurcated front end 29 of the handle and has one edge projecting forwardly of the handle. A conventional set screw 3| secures the shaft 28a in position and projects downwardly from the front end of handle 21 to function as a guide foot for the handle during transverse sliding movement thereof. A guard 30 closes the upper portion of the dressing wheel.

A transverse rest bar 32 extends between the rear portion of the flanges I9 on which the rear end of the handle 21 may rest to prevent downward tilting movement of the rear end of the handle or upward tilting movement of the dressing wheel,

In the operation of the device the bracket 5 is attached to the guard I of the grinding wheel in a manner as illustrated in Figures 3 and 4 of the drawings and the table H5 is secured in an adjusted position on the table rest M.

The rod 2| is adjusted in the slots 20 in any desired position for contact of the dressing Wheel is moved transversely of the rod 2| by handle 21 whereby to rest on the surface of the grinding wheel.

The front edge of the table rest l4 may be formed with a notch 32 to receive the grinding wheel for positioning the attachment more closely thereto and if desired clamping blocks 33 may be positioned at the sides of table rest M where smaller table rests are used.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as hereindescribed and the scope of the appended claims.

What I claim:

1. A grinding wheel dressing device comprising a table, means securing the table in position adjacent the periphery of a grinding wheel, a transverse bar carried by the table, a handle slidable on the bar and pivoted thereon for vertical swinging movement, a dressing wheel journaled on the front end of the handle for contact with the periphery of the grinding wheel, said transverse bar being adjustable forwardly and rearwardly on the table to move the dressing wheel toward or REFERENCES CITED The following references are of record in the file of this patent:
