JAMES DRONSFIELD, OF OLDHAM, ENGLAND.
MACHINERY FOR GRINDING OR SURFACING METALLIC AND OTHER CYLINDRICAL BODIES.
To aZZ whom it may concern:
Be it known that I, JAMES DRoNsrrenD, a subject of the King of Great Britain and Ireland, residing at the Atlas Works, Oldham, in the county of Lancaster, England, cardgrinding-machine maker, have invented new and useful Improvements in Machinery for Grinding or Surfacing Metallic and other Cylindrical Bodies, of which the following is a specification.
This invention relates to grinding or surfacing machines, for grinding heavy bowls or rollers, or shells, and such like, by means of a traversing grinder' moved endwise on a shell, the class of machine being shown in my former United States Patent No. 854,341, May 21st 1907.
The present invention covers developments which allow the bowl bearings or sustaining jaws, carried by the transverse setting slides, t0 slue or rotate in sympathy with the bowl when either of such bearings is set up or adjusted; to an improvement in the bowl driving gear and way of tensioning the chain; to improvements in connection with the means for supplying cooling liquid to the bowl being ground; andto improvements in and in the manner of mounting the bearings for the grinder shell.
The improvements, in this form of grinding machine, are illustrated in the attached four sheets of drawings.
In the said drawings z--Figure 1 shows an end elevation, partly in section, and illustrates certain of the improved features in connection with grinders of the type in question. Fig. 2 is a detail plan view of part of the driving gearing. Fig. 3 is an end view of the grinder. Fig. 4 is an enlarged detail view, and indicates how the liquid conveying pipe lengths are jointed. Fig. 5 is a seetion of Fig. d. Fig. 6 is a sectional view of part of a grinder, and shows a modification in the way of arranging for the bearings or supports to slue or rotate when required. Fig. 7 illustrates a front elevation of the grinding machine, partly in section.
In my .former United States patent, a main bed a was used, and, sliding on this were supports b b, capable of being adjusted in the direction of length of the machine, and of being clamped to the bed a. These supports formed auxiliary beds for slides, similar to those marked e, and which were adjustable transversely, such slides carrying Patented Sept. 19, 1911.
Serial No. 606,868.
brackets or bearings for the bowl trunnions, and, by screw adjusting means Z acting on the slides, the bowl or work c was set up to the grinder (S. New, as each slide was set up separately, after the work had been fixed in the bearings, there was a tendency to strain any comparatively light roll or shell, or, in the case of a heavy bowl the strain was thrown on the bowl supporting parts of the machine. I now make each bearing B capable of sl lling' or rotating slightly, so that the bearing can rotate to the required degree to accommodate itself and the sustained p0rtion of the bowl to any adjustment of the other bearing device transversely of the machine. The simplest way to do this, is, instead of mounting the bowl support-ing brackets directly on the slide, to attach or mount same on a plate which can swivel around a pivotal device in va horizontal plate. For example, I may force a tube f into the slide c and bore the swivel plate g to engage said tube f'. The swivel plate g is fashioned with a fixed jaw g, and a movable jaw gg, which is adjusted 1n planed ways and clamped by the bolt g3. 'lhe swivel plate g is preferably adaptcd to receive interchangeable packing plates or blocks g as shown which engage the stud f.
In a modified type, and as shown in Fig. (S the swivel device may be a V or jawed block y* having a turned base projection f* which engages with an annular recess in a slide c, adjustable transversely by the screw (Z, the slide being carried on a support Z) adjustable longitudinally. Interchangeable packing blocks .f/"X, vg, can be used on the V block. As before, the bowl or work c is driven by a chain ZL passing around the chain wheel Zig. Now, I mount the small chain wheel ZL on a pivoted bracket z', swiveling on the first motion shaft Z. A pinion y' on the said shaft Z gears with a larger pinion Z; running on a stud m. carried by said bracket, and this pinion is combined with a small pinion a, gearing into a larger pinion o'on another shaft 79 carrying the small removable chain wheel ZL. Around this small chain wheel i, the chain Zz driving the chain wheel h2 on the bowl is carried, as heretofore. Thus, all the gear wheels, after the first, are carried from the bracket z' which is prolonged and provided with means (such as the screwed spindle 2 with handle 3) whereby the bracket 'L' may be clamped or bolted when the tension of the chain is adjusted; or the mere weight of the parts may serve for the purpose. In applying the chain h, the bracket z' can be raised, by a handle 77, to readily get the chain in position, whereupon the bracket z' is lowered and clamped or fixed. rl'he wheels alwaysremain in gear, and the two first wheels ja 7c in the train, may be inside the frame or end standard as shown.
The bowl or work e is supplied with liquid, as known, and the conveying pipes Q, Q require to be jointed so that the delivery or discharge length g" may follow the grinder G. To permit this, I utilize metal pipes, as known, and I fit castings 71, r to joint two conveying lengths of pipes g, g, which castings 1", r form the halves of swivel joints, and these castings have flat faces with spigots and sockets, as shown in Fig. 5, which make good contact. A packing r2 may be introduced between the spigot and socket faces and I hold the two castings together by a stirrup or U shaped bracket s with pinching screws s, s which press the flat faces of the casting r, r together, and permit of adjustment.
In these grinding machines I have used cone bearings, and I have now simplified the way of supporting same, and, arranged for the removal of the grinder (once the grinder shell is withdrawn) without disturbing the cone bearings. Each standard is furnished with an oil well t and has a removable cap u held by bolts u. The shaft o has a cone o at each end, and, fitting this, is the bearing proper w which is carried in a squared block @c held by the cap u. Lock nuts y adjust the bearing fw to the cone n', and, a screwed end cap e, which screws on to the bearing fw and over the lock-nuts y, prevents jamming of the coned parts by abutting against the end of the squared block which latter is held by the removable cap u'. The squared block m, and the bearing w, are cut away at 2 to accommodate a ring 3 dipping into the oil in the loil reservoir t, and, this ring 3 can be moved to assume a position within limit of size of the complete bearing. By this construction, once the caps u u are removed, and theA shell 4l is lifted clear of the end standards 5, 5, the grinder 6 can be slipped off, or on, without interfering with the cone bearing at all. The complete cone bearing is thus to all intents and purpose part of the grinding roller shell but of less exterior diameter for the purpose in view.
I declare that what I claim is 1. A grinding or surfacing machine, having in combination, a main longitudinal bed, adjustable brackets thereon and Vmovable endwise, a setting slide movable transversely with means for setting same, bowl sustaining jaws thereon, a swivel connection for the said sustaining jaws whereby said sustaining jaws can accommodate themselves to the shaft or trunnion of the work, as set forth.
2. A grinding or surfacing machine, comprising a grinder, means for traversing the same, bearing jaws for the work, a cross setting slide, and a swivel connection between the bearing jaws and the cross setting slide, and means for driving the work when resting in the bearing aws comprising gear wheels on the main shaft, a bracket, gear wheels on the bracket, and connected gear to the work as set forth.
3. A grinding or surfacing machine, having in combination, bowl sustaining bearings for the work, a support for said bearings, a sluing connection between bearings and said support, means for carrying said support, gear for adjusting same transversely, longitudinally adjustable brackets arranged over a well or tank and pipe connections therefrom, swiveling joints for the pipe connections, and a discharge pipe, all as described.
4;. A grinding or surfacing machine, having work supporting devices, a cross slide, pivoted or sluing connections for such cross slide, gear for adjusting such cross slide on brackets, brackets carried on a bed, a tank in said bed, pipe connections, a pump, swivel joints, and discharge pipe, a grinder, a grinder shell, a cone bearing, adjusting devices for same, a lubricant well, and a ring dipping in said well, all as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
