Specification of Letters Patent.
' Patented May 26, 1914.
Application filed January 20, 1912. Serial No. 672,502.
To all whom it may concern:
Be it known that 1, DAVID F. DoMizr, citizen of the United States, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Gaging-Tools for Piston-Rings, of which the following is a specification.
The object, construction and application of my improved gaging tool for piston rings are herein set. forth with sufficient clearness to enable those skilled in the art to which itappertains, to make and use the same.
The object of this invention is, to provide a tool for simultaneously machining both lateral faces of a piston ring, and at the same time sizing the same to an exact and definite width.
When the tool here shown. is used, it is necessary that a special form of chuck for the ring be employed, such a chuck, for instance, as that shown and described in a certain application for Letters Patent of the United States, filed by me on the 21st day of April, 1911, Serial Number 622,579.
The construction by means of which I attain the object above set forth, is clearly illustrated in the drawings, the respective figures of which are as follows:
Figure 1 is a plan view of the tool. Fig. 2 is a side elevation of same.
The construction here shown consists of a base 1, upon which are pivotably secured two tool- holders 2 and 3. The pivotal point of said levers may be suitable bolts, as 4, 4, which pass through the same; the lower end of said bolts being firmly secured in base 1. From said pivotal. point, said holders extend forward and project somewhat beyond the front end of base 1. A substantially horizontal cutter-slot is formed in the forward end of each of said holders, for the reception of the cutters 5, 5. Suitable means, as set screws, 6. 6, are provided for securing said cutters firmly in position. The juxtaposed points 7 of said cutters are formed into cutting edges and are adapted to operate simultaneously upon the lateral faces of a piston ring, for the purpose of accurately gaging the width thereof.
Holders 2 and 3 are formed into or provided with rearwardly-extending levers 2, 3, respectively, for the purpose of adjusting the thereto attached tool-holders with their cutters, in such a manner as to vary the distance between points 7 whereby the desired width of the ring to be operated upon is secured.
The rear end of base 1 is provided with two upwardlyextending lugs 8, 8, between which the rear extremities of levers2 and 3 are positioned. A screw 9 passes through said lugs and also through a slot or gap 10 in the rear extremity of each of said levers. Threaded adjusting-nuts 11, 11, 12, 12 are mounted upon screw 9, one nut upon each side of the respective levers 2, 3, and when an adjustment of the cutters is to be made, as, for instance, adjusting the points 7 far ther apart,nuts l1 and 11 are moved toward each other the required amount or distance, then nuts 12 and 12 are moved in the same direction, and in said movement they impinge upon and move the respective levers with them, thus causing desired adjust ment, until the ends thereof are firmly clamped between said nuts, and this permanently secures said adjustment. Nuts 11, 11, 12, 12, are each provided with a graduated index A for the purpose of determining and indicating the amount of adjustment made thereby.
My improved gaging tool is adapted to be applied to many forms of machine tools, such as lathes, milling machines and boring mills, and can be used for many other kinds of work in addition to its employment upon piston rings, such as finishing the edges of gear blanks, pulleys, fly wheels, etc. Said tool has been specially designed, however, for use with an improved piston ring finishing machine, shown and described in a certain application for Letters Patent of the United States, filed by me on the 20th day of January, 1912, Serial Number 672,504.
For the purpose of attaching my improved tool to the slide rest of a lathe, the table of a milling machine or the proper element of any other suitable machine tool, a slot 13 is formed through base 1 for the passage and reception of a bolt or any other suitable securing device.
hat I claim and desire to secure by etters Patent. is
1. A gaging tool for piston rings consisting of the combination of a base arranged to be attached to the proper element of a suitable machine tool, tool-holders pivotably attached to said base, there being a substantially horizontal tool-slot in the front end of each of said holders, a cutting tool secured in each of said slots, with the cutting points of said tools arranged in juxtaposition for the purpose of simultaneously operating upon the lateral faces of a piston ring, means secured to said holders for the purpose of adjusting and retaining the adjustment of said holders, adjusting means carried by said base and engaging said adjusting means for the purpose of adjustably actuating said tool-holders and securing the adjustment thereof.
2. A gage-tool for piston rings consisting of the combination of a base arranged to be attached to the proper element of a suitable machine tool, tool-holders pivotably attached to said base and each provided in the front end thereof with a slot for the reception of a cutting tool, a cutting tool secured in each of said slots, with their cutting points in juxtaposition for the purpose set forth, levers extending rearwardly from said holders for the purpose of laterally adjusting said tools, there being a gap in the rear extremity of each of said levers, a screw carried by said base, arranged transversely to said levers and passing through said gaps, and adjusting nuts carried by said screw, one of said nuts being positioned upon each side of said lever and adapted to move the same laterally for the purpose of adjusting said holders, and to retain the same at the desired point of adjustment.
3. A gaging tool for annuli, consisting of the combination of a base, arranged to be attached to a suitable element of a machine tool, tool holders adjustably attached to said base, a cutting tool secured in one end of each of said holders, with their cutting edges arranged in uxtaposition for the purpose of simultaneously operating upon both lateral edges of an annulus, means varying the proximity of said cutting edges and means indicating the degree of said variation.
In testimony whereof I afiix my signature in presence of two witnesses.
