CYLINDER-BORING MACHINE.
Specification of Letters Patent.
Patented March 31, 1908.
Application filed anuary 18, 1908. Serial No. 411,408.
To all 'whom it may concern:
Be it known that I, WILLIAMJOSEPHIIAG- MAN, a citizen of the United States, residing at Philadelphia, Philadelphia county, Pennsylvania, have invented certain new and useful Improvements in Cylinder Boring Ma chines, of which the following is a specification.
This invention pertains to improvements in machines for boring steam engine cylinders, suchas cylinders of locomotives having a cylindrical steam chest disposed parallel with the cylinder and having pipe connec tions resenting their ends at thefends bf the cylin( cr and 'having their axes parallel with the axis of the cylinder these pipe connections not extending through from one to the other.
rl`he improvements will be `readily understood from the 'following description taken in connection with the accompanying drawings in which Figure 1 is a front elevation `of `a cylinder boring machine exemplifying my invention,
the driving mechanism being omitted, and the main boring bar being broken away to show the secondary bar in its rear: Fig. 2 an end elevation of the same, showing the end appearing at the right of Fig. 1: and Fig. 3 a similar end elevation with the right-hand housing omitted and the main and secondary boring bars appearing in vertical transverse section in the plane of line a of Fig. 1.
In the drawings :-1, indicates the bedplate of the machine: 2, one of the housings projecting upwardly therefrom: 3, the other housing, shown as arranged for adjustment longitudinally on the bed-plate: 4, a bearing mounted for adjustment on each housing in a' horizontal lpath at right angles to the aXes of the boring bars: 5, screws in ythe housings for adjusting these bearings: 6, the main boring bar, journaled in the bearings 4, this bar to have the construction and rovision usual in the boring bars of cylinc er boring machines: 6a, a projection from one `end of this j main boring bar for the reception of the usual driving gear: 7, the secondary boring bar having its ends journaled in the two housings parallel with the main boring bar, this secondary boring bar having a diameter less than that of the main boring bar so as to adapt it to deal with the cylindrical steam-chest of such a cylinder asv has been referred to: 8, the proj ecting end `of the secondary boring bar 7 for the reception of the usual driving `gear for driving this bar: v9, a super-housing provided with a vertical face yand mounted for sliding .motion horizontally on the upper portion of housing 2: 10, a screw for adjusting the super-housing 9 in a direction to and from the aXis of the main boring bar 6: 11, a bearing -bracket mounted for vertical sliding motion on the vertical face of super-housing 9: 12, a screw for vertically adjusting this bearing-bracket: 13, a tool-bar journaled in the bearing-bracket 11: 14, the projecting outer endio'f this tool bar for the reception of a driving gear: 15, a super-.housing mounted for -horizontal `adjustment on y the top of housing 3: 1.6, a screw for horizontally ad* justing this superehousing: 17, a bearingbracket mounted for vertical adjustment on the super-housing 15 by :means of a screw after the manner of bearing bracket 11: 18, a tool-bar journaled in bearing-bracket 17: 19, a gear fast on an `end of secondary l.boring bar 7 projecting outwardly beyond housing 3 in which that bar is journaled: 20, a gear fast on the outer end `of tool-bar 18 and disposed in the vertical plane of Agear 19: 21,
an :intermediate gear engaging gears 19 and 20: 22, an `adjustable tumbler carrying gear 21 and serving in adjusting that gear for engagement with gear 20 in the varying vertical positions of the latter: 23, a tablebase mounted for sliding motion longitudinally on the 4bed-plate between the two housings and having its upper surface sloping downwardly in opposite directions from the transverse center of the table-base: 24, super-tables having their bases resting on the sloping upper surfaces of the table-base, the upper surfaces of these two super-tables being horizontal, and the super-tables being mounted for adjustment up and down the sloping surfaces on which they rest: y25, screws for adjusting the super-tables up and4 down the slopes of the table-base: and 26, facing -cutter secured at the inner ends of tool- bars 13 and 18.
The cylinder to be bored is secured to the upper surfaces of the super-tables, those two tables having their levels adjusted relative to the boring bars and relative to each other by being adjusted upon the slopes of the table-base, thus permitting the general work-holding table to adapt itself to the under side of a cylinder casting whose main body has one size and its steam-sheet a l the super-housing, a tool-bar'journaled in somewhat different size. Some of the adjustments of the cylinder-casting will be made by blocks or saddles upon the tables but the independent adjustment of the two tables provides for a nice adjustment of the axes of the cylinder and the steam-chest into coincidence with the horizontal plane of the two boring bars. j
The casting is to be so adjusted transversely of the machine that the axis of the steam-chest will coincide with the axis of secondary boring bar 7, and the bearings of main boring bar 6 are to be adjusted to or from the secondary boring bar so as to bringv the main boring bar concentric with the cylinder. Under these conditions the two boring bars may act upon the casting, the main boring bar boring and facing Vthe cylinder while the secondary bar bores and faces the steam-chest, it being understood that these two boring bars will be provided with the usual boring and facing accessories.
The facing of the ends of the pipe-connections of the casting cannot be done by means of a single bar, owing to the fact that there is no passage extending axially from one of these pipe connections to the other. Housings 9 and 15 are to be adjusted transversely of the machine to bring tool- bars 13 and 18 into the vertical planes of the ends of the pipe-connections to be faced, and bearingbrackets 11 and 17 are to be adjusted vertically upon their housings to brin the toolbars into the horizontal planes o the ends of the pipe connections which they are to face. The ends of the pipe-connections are then to be faced by means of the facing tools 26. The gearing arran ement causes motion to be transmitted rom the secondary boring-bar to tool-bar 18, and the'gears 19, 20 and 21 in connection with the tumbler provide for the varying position of the axis of toolbar 18. The gearing arrangement illustrated for getting motion to tool bar 18 rep- .resents the best that has thus far come within my contemplation.
