Specification of Letters Patent.

Application filed October 14 1910. Serial No, 586,991.

To all whom, it may concern:

Be it known that I, HENRY Hnss, a citizen of the United States, residing at- Philadelphia, in the county of Philadelphia. and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Formin Grooves and the Like Upon the Sides of Rollers, &c., of which the following is a specification, reference being had therein to the accompanying drawing. ly invention relates to machines for forming grooves and the like upon the sides of rollers and other objects, and is more particularly disclosed herein in connection with the formation of conicallyi shaped or angularly located grooves upon the rollers used in journal bearings, such grooves being intended to form abutting surfaces, whereby the end thrust on the rollers is resisted or transmitted and also the rollers are held in normal position in relation to the other parts of the bearing. It will be obvious, however, that the machine is capable of broader application and in fact may be employed to produce grooves of. various forms and location upon any desired object.

Referring to the form of rollers previ ously mentioned, it will be seen that in order to obtain the greatest accuracy and uniformity, and the least resistance and wear,

it is essential that the oonically shaped T conically 'cally shaped as to their general outline,

grooves shall be absolutely true and similar and that the position of the grooves, that is to say, their distance the rollers, shall be exactly the same in all. These results I secure by forming the grooves by the machine now to be described. I

In the accompanying drawing I have shown my invention in preferred form, and as particularly applied to the production of shaped or angularly located grooves upon the surfaces of rollers, cognut obviously such arrangement is simply by way of example and for the purpose of illustrating one form of myinvention, and

many changes and variations may be made therein without departing from its spirit. Generally speaking, I desire it to be expressly understood that I do not limit myself to any specific form or embodiment exfrom the ends of,

l a stop D ceptin so far as such limitations are specitied n the claims.

Referring to the drawing: Figure 1 is an Patented pr. 16, 1912.

elevation, partly in section, of the essential port-ions of a machine embodying my invention, and Fig. 2 1s a transverse sectional View thereof, taken substantially on the 5,

line 2-2 in Fig. 1.

As illustrated in the drawing, the rollers A A are con-ically shaped as to their general outline and it is desired to form grooves or cuts a-a upon the sides thereof, such grooves orcuts constituting in effect conical abutting surfaces for the purposes previously specified. The general conical formation of the rollers A A is however not essential to the employment of my machine, which is designed generally for the production of grooves upon any objects where they may be desired. The rollers A A are mount-ed in series between a ring C and an internal rotatable disk B, the ring and disk being suitably shaped to correspond to the form of the rollers A A, and by disposing the rollers in the manner indicated, they are brought into proper angular position to be subjected to the action of thegrinding tool D.

The tool D may be rotated in any desired manner, such for instance as the spindle D gearing'D countensha-ft D and gearing D actuated from the power driven shaft D The tool -D is splined upon the spindle D so as to be capable also of longitudinal movement thereon, which movement is controlled by a handle D and is limited by In this manner the grinding action of the tool upon the rollers A. A may extent.

The disk suitable connections whereby it' may be rotated, comprising 'a shaftB and geziring B connected to the power driven shaft D Because of the contact of the disk B with the rollers A A, the latter are caused to 1'0- tate individually, so as to present successively and continuously their sides to the action of the cutting edge of the tool D wherea-a are formed. As shown:

ed in the machine in substantially the a'n-V 'be governed and regulated to any desired B is shown as provided with 1 gular' relation to each other that they ocers need not be arranged in the exact anfilipy inthe journal bearing, and it will be seen that by the employment of the'machine, absolute un formity is secured as to the position of the groovesin the sides of therollers, and also the exact similarity of the grooves formed therein. It will be obvious that my-improved machine may be employed in many different "ways without'departing from the spirit of my invention. Thus, for instance, the roll gular relation previously described, all that is essential in this respect being that the angular relation adopted should be the one Calculated to give the desired pitch and position to the grooves. As previously pointedout, also, the main portion of the object operated upon need not beconical, as in the particular illustration given. Again, the internal disk B might remain stationary,

and the external ring 0 be rotated to profluce the same result, namely, 'the indix-y' idual rotation of the rollers or otherwork.

"andI regard them all as comprised Within Or again, both the external ring and the internal disk may be rotated, or other and entirely difi'erent means may be employed to secure'the rotation of the work. Similarly,- the particular means employed for forming the-grooves maybe entirely different from that herein disclosed, and suchmeans might ebnsist-of milling tools, wood working tools, etjt, dependent upon the material employed andthe nature of the result required. Not only may,.the p,osition and, angular relations of the groovesmpon the sides of the rollers.

be varied to suit the particular needs, but in addition thereto, their I conformation and shape may be altered at will, as for instance by changing the shape, character-and location of the cutting or grindinginstruments. Aga n, the'form of the tool may be varied as;j:desired in accordance with the character of the/work, to be performed, thereby; and "similarly itslocation may be changed, as These and many other variations Wlll. sugwell as its point of application to the work.
