GRINDING APPARATUS.
Specification of Letters Patent.
Patented Jan. 29, 1907.
Application filed May 20, 1904.. Serial No. 208.934.
To all whom, it may concern:
Be it known that I, GEoRe BENICKE, a subject of the Em eror of Germany, residing at Offenbach-on-tlie-Main, in the Empire of have invented certain new and useful Improvements Relating to Grinding Apparatus, of which the following is a specification.
This invention relates to grinding apparatus, and more especially for grinding the crank-pins having counter-cranks.
The accompanying drawings represent an apparatus for grinding the crank-pins of locomotive-wheels, whereby the grinding operation may be performed upon the crank when in position upon the wheel; and the invention has for its object to provide a simple construction readily permitting the necessary adjustments.
Figure 1 is a longitudinal section of the apparatus. Fig. 2 is an end view showing the ell-shaped casing. Fig.3 is a section on the Fig. 1 is a sectional plan line C D of Fig. -2.
The arrangement and operation of the apparatus are as follows:
A cylinder 6, which is bored with an inclined hole and provided with teeth 4, is mounted within a cylindrical casing 5, upon which is mounted a separate lateral box 23, Fig. 3, in which gear-wheels 21 22 are carried. The cylinder 6 is provided with an extension 3 at one end, upon the reduced extremity of which screw-threads arecut and on which a hand-wheel 2, provided integrally upon an internally-threaded sleeve, is mounted, by the operation of which hand-wheel 2 the extension 3 and the cylinder 6 are moved. In the angularly-bored cylinder 6 another cylinder 1 is mounted, which is provided with a horizontal bore for the purpose of carrying the spindle 15. The cylinder 1 is provided at one end with a flange having a groove 10 therein, in which enters a flange 9, which is mounted upon the end of the cylindrical casing 5, so as to be capable of movement therein, so that thus the spindle may be moved out of the center line of the apparatus. This movement is effected by turning the handwheel 2, whereby the cylinder 6 moves upon the cylinder 1. Therefore inasmuch as the cylinder 6, guided in the cylindrical casing 5, cannot yield the cylinder 1 and the spindle 15 carried thereby is forced to move on the turning of the hand-wheel 2, so that thus on the turning of the hand-wheel 2 the cylinder 1 is moved from the center, which it is permitted to do by the provision of the groove 10. The cylinder 1, upon which the cylinder 6 moves, is connected with the latter by means of a key, which runs in a longitudinal groove 8, provided on the cylinder 1, so that when the cylinder 6 is turned by the gear 21 22 the cylinder 1 and the spindle 15 is also caused to rotate.
Upon the flange 7 of the cylinder 1 a bellshaped casing 11 is carried, which is connected to the flange aforesaid by means of screws 12, as illustrated. This bell-shaped casing 11 is of such dimensions that the crank 16 has ample space afforded for its reception. Upon the casing 11 a segment-guide 18 is provided, as illustrated in Fig. 2, upon which the grinding-wheel 17 is fixed upon an arm 19, which can be moved in the guide 18 according to requirement.
The spindle 15 is provided at its extremity with a pulley 13, upon which a belt 14 passes, and also upon a pulley 25, which is fitted upon a spindle 24, upon which a pulley 20 is also mounted, around which a cord is passed, which passes also over the coincident pulley 26, which is mounted. upon the spindle of the grinding-wheel, so that when the pulley 26is rotated the grinding-wheel 17 is caused to rotate. This construction is more especially to be seen in the cross-sectional view, Fig. 4.
As soon as the cylinder 6 is set into rotation by the operating-gear the cylinder 1 and the: spindle, and therefore also the grindingwheel, rotate, shaped casing 11, which is in absolute connection with the cylinder 1, must rotate therewith. The grinding-wheel 17 will therefore, besides rotating upon its own axis, turn upon the axis of the spindle 15.
The locomotive-crank 16 (illustrated in Fig. 1 in position to be ground) is, with the wheel, fitted. upon a strong head-stock or carrier, which by means of a slide can be laterally moved, and thus adjusted into proper position with reference to the grinding-wheel. The approximate adjustment of the emerywheel 17 with reference to the work-piece can be efiected upon the guide-segment 18, while fine or exact adjustment is effected by means of the hand-wheel 2.
and at the same time the bell- The adjustment of the grinding-wheel with reference to the work-piece can be effected when the wheel is rotating.
It will be understood that the grindingwheel 17 can be fixed to the left or to the right of the frame.
