Application February 2, 1945, Serial No. 575,802
. 4 Claims.
The device forming the subject matter of this application is adapted to be employed for dressing the inner surface of a cylinder, or for cutting a bevel. The invention aims to provide novel means for holding the device in a cylinder, to supply novel means whereby the driving motor and associated parts may be adjusted inwardly and outwardly, to enable a grinding wheel to co operate with a cylinder, and to provide novel 'means whereby the grinding wheel and associated parts may be carried around in an orbit to effect the grinding of the bore of a cylinder.
Although preferred form are shown in the drawings, it will be understood that a mechanic who abides by what is claimed may make such changes as his skill may direct, without departing from the spirit of the invention.
In Figure 1 of the drawings there is shown in side elevation, a device constructed in accordance with the invention;
Figure 2 is a cross-section wherein the cylinder is indicated;
Figure 3 is a sectional view showing the construction of the brace;
Figure 4 is an elevation wherein parts are broken away, means being provided whereby the grinding wheel may work about an axis other than an axis parallel to the spindle.
In carrying out the invention, there is provided a spindle I, equipped near its upper end with a transverse shoulder 2, the spindle having a wrench-head 3 at its upper end.
A grip is provided, and includes a collar 4, mounted on the spindle I and abutting against the shoulder 2. To the collar 4, upper, radial links 5 are pivoted at 5 for movement parallel to the spindle I. The outer ends of the links 5 are pivoted at I to jaws 8. The jaws 8 preferably are in the form of straight, parallel bars. The outer ends of lower links 9 are pivoted at Iii to the jaws 8, the inner ends of the links 9 being pivoted at II to a traveller I2, preferably a nut, into which the spindle I is threaded, as shown at It.
A socket I5 is mounted to rotate n the spindle I, between the nut 3 and the shoulder 2, and carries a transversely projecting bracket, including an inner member I and an outer member I! connected by a pintle la, a hinge thus being afforded, the outer member I! of the bracket being capable of horizontal swinging movement. The outer end of the outer hinge member ET is secured rigidly to a tubular bearing 59, support ing a motor 20, the shaft 2I of which is journaled in the bearing. To the lower end of the shaft ZI of the motor 20, a cylinder dressing instrumen- 2 tality, such as a grinding Wheel 22 is secured at 33, the axis of the shaft 2| being disclosed parallel to the spindle I.
A longitudinally extensible brace is provided and includes a tubular inner member 23, which is pivotally mounted at 24 on socket I5, for swinging movement in the direction at right angles to the longitudinal axis of the spindle I. An adjusting wheel 25 is provided and includes a tubular member 26, located in the outer end of theinner member 23 of the brace, and held therein for rotation. as indicated at 21. Into the adjusting wheel 25 and its hub 26 is threaded the outer member 28 of the brace, the outer end of the outer member 28 being pivoted at 29 to the bearing ill.
The device is placed inside the cylinder 30 which is to be ground. The spindle I is rotated, by means of a wrench (not shown) applied to the wrench-head 3, and the nut or traveller I2 moves longitudinally of the spindle. The links 4 and 9 crowd the jaws 8 outwardly and cause them to grip the bore of the cylinder 30.
By means of the hand wheel 25, the length of the brace 23-28 is varied until the grinding wheel 22 cooperates with the bore of the cylinder 30.
The motor 20 rotates the shaft 2|, and the shaft rotates the grinding wheel 22. The bracket II-IB is moved in a circle by hand, the socket I5 rotating on the upper part of the spindle I, Any irregularity in the bore of the cylinder 30 is ground away by means of the wheel 22.
The device is capable of beveling an object shown at 3| in Figure 4. Under such circumstances recourse is had to a sleeve 34 mounted on the spindle I and having an offset finger 32, whereon the member I5 is mounted. It will be noted that owing to the inclination of the finger 32, relatively to the longitudinal axis of the spindle I, the grinding wheel 22 is so arranged that it will bevel the device or object which appears at 3|.
What is claimed is:
1. A grinder comprising a spindle having a shoulder, a collar wherein the spindle is rotatable,
" the collar engaging the shoulder, a nut spaced from the collar and threaded On the spindle, links having their inner ends pivoted to the nut, links having their inner ends pivoted to the collar, circumferentially spaced jaws, the outer ends of all the links being pivoted to the jaws, a motor having a shaft, a dressing tool attached to the shaft, and means for mounting the motor on the spindle for movement in an orbit.
2. A grinder comprising a spindle, a cylinder grip carried by the spindle, a socket rotatable on the spindle, a, hinge bracket comprising an inner member secured to the socket, and an outer member pivoted to the inner member and including a bearing, a motor carried by the outer member and comprising a shaft journaled in the bearing, a rotatable dressing tool arried by the shaft and having its axis of rotation disposed parallel to the longitudinal axis of the spindle, and a longitudinally adjustable brace extended across the angle defined by the inner and outer members of the bracket.
3. A grinder comprising a spindle, a sleeve rotatable on the spindle and having a, finger projecting at an acute angle to the longitudinal axis of the sleeve, a socket carried by the finger, a hinge bracket comprising an inner member secured to the socket, and an outer member pivoted to the inner member and including a bearing, a motor carried by the outer member and comprising a shaft journaled in the bearing, a rotatable dressing tool carried by the shaft and having its axis of rotation disposed at an acute angle to the longitudinal axis of the spindle, a
longitudinally adjustable brace extended across the angle defined by the inner and outer members of the bracket, and a cylinder grip carried by the spindle.
4. A grinder comprising a, spindle, a socket rotatable on the spindle, a laterally extended bracket comprising an outer member, and an inner member secured to the socket, a pivotal connection uniting the bracket members, a bearing on the outer bracket member, a motor having a shaft carried by the bearing, a rotatable dressing member carried by the motor shaft and having its axis of rotation disposed parallel to the axis of the socket, an inner brace member comprising a sleeve pivoted to the socket, and an outer brace member pivoted to the bearing, an adjustingwheel including a hub journaled in the inner brace member, and means for holding the hub in the inner brace member for rotation, the outer brace member being threaded into the adjusting wheel.
