DRESSING TOOL Filed Sept.' '7, 1943 Patented May 23, 1944 UNITED STATE DRESSING TOOL John N. Stewart, Detroit, Mich.
Application September 7, 1943, Serial No. 501,477
2 Claims.
This invention relates to a tool for dressing and truing a grinding wheel or similar device, and has for the primary object the provision of a device for the stated character which is in the form of an attachment readily adaptable to most any type of grinding machine which is provided with opposed work centering elements employing the latter for the pivotal mounting of the device on the machine and may be easily and quickly adjusted to bring the cutter thereof into a selected angle with respect to the work and also makes provision for the adjustment of the cutter relative to the work as the dressing operation progresses.
With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.
For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a top plan view illustrating a dressing tool constructed in accordance with my invention.
Figure 2 is a side elevation, partly in section, illustrating the device.
Figure 3 is a transverse sectional view showing the device.
Referring in detail to the drawing, the numeral 5 indicates a mounting of substantially U shape including an elongated connecting portion 6 provided with right angularly disposed end portions I, the outer faces of which are provided with sockets 8 to receive opposed centering elements 9 of a grinding machine of most any type and not shown. The centering elements received within the sockets 8 permit the mounting to readily pivot on said centering elements. The connecting portion 6 is increased in width, as shown at Ill, and has scale markings ll arranged thereon for coaction with scale markings l2 formed on a base I3 of a tool holder I l. The base 13 is shaped similarly to the enlarged portion ll] of the mounting and is adapted to rotate thereon. The holder I4, which forms an integral part of the base I3, is of substantially rectangular shape and has formed therein a recess closed by a removable plate IS.
A pivot pin it threads into the base and a portion of the holder l4 and is adapted to extend freely through an opening provided in the mounting 5, and has threaded thereon a knurled nut l1.
The tightening of the nut l! on the stem IE will secure the base I3 of the holder M in any of its adjusted positions on the mounting.
Slidably received within the recess of the holder I4 is a bar l8 forming a tool holder, one end of which is provided with an opening to receive the shank IQ of a cutter 20. The cutter may be of the diamond type and is disposed laterally of one of the side faces of the holder and the other end of the latter is equipped with a handle 2| to permit the operator to impart sliding movement to the holder in either direction for the purpose of adjusting the cutter with respect to the work as the dressing operation progresses.
A stem 22 is threaded in the enlarged portion ill of the mounting 5 and depends therefrom and has threaded thereon a knurled sleeve 23 adapted to be brought into contact with a bed or supporting surface of the grinding machine for the purpose of adjusting the inclination of the mounting 5, it being understood that the mounting pivots on the centering elements 9 of the grinding machine. "This will permit the cutter element to be raised and lowered with respect to the work and to adjust the cutter element toward and from the work and at a selected angle, the nut H is released and the base I3 is turned on the mounting, the operator noting the scale markings on the base as well as on the mounting in making this adjustment so that the cutter element will be arranged at a selected angle with respect to the work. As the dressing operation proceeds, the operator may slide the tool holder [8 in the tool holder M for advancing the cutter as rapidly as desired during the dressing operation.
Thus it will be seen that a very compact, simple and durable tool has been provided which may be easily mounted on the centering elements of most any grinding machine and will permit accurate dressing operations to be car-,
ried out on the work with a minimum expenditure of manual efiort and that the cutter element may be easily and quickly brought into a selected angle with respect to the work.
While I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.
Having thus described my invention, what I claim-is:
1. In a dressing tool, a pivotally supported mounting, a tool holder rotatably attached to the mounting, a tool slidably supported by said holder, said holder and mounting having coacting scale markings thereon, and an adjustable means between the support of said mounting and the latter for adjustably restraining the pivotal' movement of the mounting.
2. In a dressing tool, a substantially U shaped mounting including a connecting portion and right angularly disposed end portions provided with recesses to receive centering elements of a grinding machine, said connecting portion having a scale thereon, a base having a scale coacting With the first-named scale and rotatably secured on the connecting portion and including means for releasably securing the base for rotation, a holder forming an integral part of the base, a tool rod slidably mounted in said holder and including a cutting tool at one end and a handle at the other end, a pin secured to the connecting portion of the mounting and depending therefrom, and a sleeve threaded on said pin to contact a bed of the grinding machine for adjustably restraining the pivotal movement of the mounting on the centering elements.
