Specification of Letters Patent.
Eatented .Tune 16, 1908.
Application 1ed March 25, 1907. Serial No. 364,527.
. Jersey, have invented certain new and useful Improvements in Boring-Mills, of which vthe following is a specification.
My invention relates to boring mills vand it is especially adapted-for use in connection with what is known as the floor-plate system, in the finishing or machining of heavy work ilixch as the rotors of large dynamos and the In the Hoor-plate system the floor is made up of plates of iron accurately nished on their upper surfaces and rigidly held in position and provided with holes or slots so that machine tools such as drilling, milling and slotting machines etc. may be easily moved up to the work and securely held in accurate alinement while performing their work.
The object of my invention is to provide a boring mill of massive construction especially adapted to be used in connection with or as a part of a floor-plate system and which shall be simple and effective in its construction and operation.
The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims. I In the drawings accompanying and forming a part of this specification Figure 1 is a vertical central section through the axis of the mill. Fig. 2 is a plan of the mill, portions of the face-plate being broken away and shown in section.
Referring to the drawings, numerals 1 and 2 represent respectively the outer and inner annular walls or piers which support the boring mill; 3 represents a movable annular table or face-plate whose top, or working surface is flush with the surface of the floor-plates 4. The face-plate 3 is made up of an annular ring 5, heavily webbed on its under side, to which is Secured in its central opening the hub 6 provided with a projecting flange 7 upon which the ring 5 rests. The ring 5 is strengthened by the radial webs 8 terminating at the outer periphery in the thickened rim 9. To the under side of the rim a segmental rack or gear 10 is rigidly bolted, With this gear wheel a pinion 11 meshes, the same being driven through suitable gears 12 from a horizontal shaft.
- Securely mounted upon the inner pier4 2 I provide a central stationary face-plate or king post 13 which presents a fiat surface' flush with the surface of the face-plate and an upwardly projecting centrally disposed body with an annular shoulder or seat 14 disposed about the lower part thereof. This king post is heavily built to take the Weight of the annular face-plate on the seat 14 and is suitably reinforced by ribs 15. The body of the king post is slightly conical and tapers upwardly to a slightly reduced diameter. The annular face-plate rests upon the seat 14 in the manner illustrated and it is brought into accurate axial alinement, or centered, by means of a wedge sleeve or ring 16 which is forced down from above into the space between the king post and the annular faceplate; the said wedge sleeve being secured to the hub of the annular face-plate through a flange 17 o verhanging the edge of the opening in the hub as shown. This wedge sleeve is adapted to be adjusted to take up the wear. The upper surface of the kin post is plain or fiat as shown and is forme With a groove at its edge which receives a packing ring 18 as indicated.
From the construction described it will now be understood that as the facelate is rotated its weight will be taken by t e seat 14 through it is held in axial alinement by the king post 13.
The face-plate i s covered by anchor-plates 19 having separated undercut edges whereby radial T slots 20 are formed that are suitable for boltin down heavy machine parts upon the face-p ate as will be readily understood. These anchor plates and the other parts of the face plate are all flush with the floor so that when not in use the face-plate virtually constitutes sim ly a part of the floor. I provide means or sup orting the face-plate near its outer edge whiclh operates to give the face-plate additional support when carrying an eccentric load or an overload. For this purpose I mount a series of foundation plates 21 with adjusting blocks on the outer pier 1, upon which rests the auxiliary bearing ring 22 which is adapted to be adjusted up to touch against the face of the ring 10 by suitable wedge-keys or gibs 23. It should be understood however, that the bearing ring loader eccentric oad.l
22 normall does not take any art of the weight of' t e face-plate and loa but is intended to hold the face-plate true in case it should tend to sa at its edge from an over- The king `post 13 is formedwith a central opening 24 which can be closed by a remova le taper plug or cover 25. When the lug is removed a boring bar of a boring mac ine or the tool of a slotting machine may be introduced from below which can o erate u on the interior of a machine part such as a cy inder or rotorI bolted to the face-plate or to the king ost. The faceplate may be held fixed uring this o eration but if the machine part is a large one 1t ma be fixed to the faceplate and as the face-p ate revolves the exterior of the work may be finished by a tool mounted on -the floor while the interior is nished by a tool carried on a boring bar introduced through the opening 24 4as suggested. The lug is formed with a downwardly exten ing tubular neck 26 havin threaded opening 27 in the lower end thereo The bearing surfaces are lubricated by oil introduced under ressure through a supply pipe system 28 and) carried away by a return p ipe system 29, the seat 14 and the bearingring 22 being provided with lips 30 asshown, to retain the oil.
In the upper face of the king post 13 I rovide two or more annular slots 31 and the ottom of these slots are provided with threaded bolt holes 32 spaced equal distances apart as shown. These grooves are concentric with the axis ofthe boring mill and facilitate the -it in the grooves and being rigidly secured in position by' bolts seating in the bolt holes 32.
On account of the concentric position pf the slots 31 it is possible to remove the toolpost referred to and replace it in center without ein loying any other centering means. These s ots are at a measured distance from the axis of the mill `and facilitate laying off radial measurements for the work. Around the outer edge ofthe face-plate 3 a continuous rabbet groove 33 is formed in the stationary floor plate and in this groove is placed a packing ring '34 thatis finished at its inner edge to the diameter ofthe faceplate. It isunnecessary for the outer edge of this ring to touch the side of the rabbet groove; it may simply make a rough fit as indicated. This ring like the packing ring 18 excludes chi s and dirt from the working parts. The si e-face or outer edge of the ace-plate 3 is provided with a dee undercut or inclined groove 35 in which is guided the upper edge of an a ron or shield 36,. secured at its bottom e ge to the stationary foundation parts; this apron is made of sheet metal and extends continuously around the machine, acting as a covering to protect the working arts beneath, as indicated in Fig. 1. On the interior of the king post 13 the ribs 15 are formed with notches 37 which are at the same level and at a measured distance below the face of the face-plate; their presence enables a boring bar set u in the center'opening to be accurately a ined vertically.
0n account of its great size the face-plate 3 is most conveniently formed in sections bolted together. The use of the segmental anchor plates is also advantageous as they are readily handled and set in place. While I have describedthe face-plate as being iiush with the floor, this arrangement is not essential.
Having thus described my invention what I claim is:
1. The combination with a s'tationarycentral face-plate of a movable annular faceplate surrounding said stationary face-plate apd means for driving said annular faceate.
3, n a floor-plate boring mill the combination with a stationary circular facezplate l surhaving a central opening adapted to receive said stationaryv face-plate.
4. In a floor-plate boring mill the combination with a stationary circular face-plate having an annular seat below its exposed surface and a conical body between its exposed surfaee and said annular seat, of an annular rotatable face-plate adapted to rest upon said annular seat and an adjustin ring between said conical body portion and tllie central opening in said annular faceate. p 5. In a floor-plate boring mill the combination with a stationary circular face-plate having an annular seat below its exposed surface, of an annular rotatable face-plate adapted to rest upon said annular seat and having a central opening adapted to receive said stationary facelate, and a movable uide ring disposed eneath said annular ace-plate at a part removed from its central opening, and means for movin said guide 7.
