JAMES BUCHANAN, OF WEST ALBANY, NEW YORK.

LOCOMOTIVE OR ENGlNE CYLINDER BQRING MECHANESM.

SPECIFICATION forming pafi of Letters PatentNo. 531,773, dated January 1, 1895. Application filed June 1, 1894. Serial No, 513,118. (No model.)

To all whom, it may concern.-

Be it known that I, J Anne BUCHANAN, a citizen of the United States, residing at West Albany, in the county of Albany and State of New York, have invented a certain new and useful Locomotive or Engine Cylinder Boring Mechanism, of which the following is a speci fication.

Heretofore it has been customary, so far as I am aware, when the cylinder of a locomotive became worn or enlarged to bore it out when in place on the locomotive by means of mechanism operated by hand, so that the piston.

would work properly therein. lhis method of operating the boring mechanism by hand, dad, was exceedingly costly, as well as consuming a large amountof time and thus keeping the locomotive out of service longer than desirable The object of my invention, therefore, is to provide means whereby the cylinders of a locomotive can be bored out or trned when in place on the locomotive by the application of power, 850., by which means a large amount of time and inconvenience can be saved.

Another object of my invention is to provide devices for facing off the valve seat of the valve chest, which devices are operated in conjunction with the above mentioned bor-' ing devices.

Another object of my "invention is to provide improvements in an oscillatingengine to be used in operating my cylinder boring devices.

A further object of the invention is to provide means for giving an intermittent feeding motion to the boring or cutting tool used for truing the cylinder.

My invention, therefore, consists in a boring mechanism adapted to be fitted upon, or applied to, a locomotive or engine cylinder in such manner that the interiorof said cylinder can be evenly and properly bored while it remains in position on the locomotive.

The invention also consists in the application to such a mechanism of an independent engine adapted to operate said mechanism and to be driven by steam or compressed air from said'locomotive or other means carried thereby.

The invention aslo consists in means for giving the boring tool a continuous rotary motion with an intermittent feed so as to produce the most perfect boring within the cylinder. This feature is in contradistinction to the usual practice of advancing the tool continuously during its revolutions.

*The invention also consists in means for facibg the valve seat for connecting said means with the boring devices so that they may opcrate them simultaneously by the same power.

The invention also consists in novel means for attaching the boring devices and their engine to the cylinder and locomotive so as to produce perfect action in the parts while permitting of quick and ready adjustment.

The invention further consists in the novel details of improvementand the combinations of parts that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part hereof, wherein-- Figure l is a partly broken side elevation of a locomotive showing my improvements in position on thecylinder for boring or trning it. Fig. 1 is a detail hereinafter explained. Fig. 2 is an enlarged side view of the cylinder and the attached boring devices. Fig. 3 is a side View of the engine cylinder for operating the boring devices. Fig. 4 is a longitudinal section thereof. Fig. 5 is an enlarged plan view of the locomotive cylinder and the attached boring devices. Fig. 6 is a side elevation of the engine for operating the boring devices. Fig. 7 isa view looking from the opposite side thereof. Fig. 8 isan end view thereof, showing means for attaching said engine to the locomotive cylinder. Fig. 9 is a partly sectional detail view showing means for giving the boring tool an intermitting feeding motion. Fig. 10 is a cross section thereof looking in the direction of the arrow to, and Fig. 11 is asimilar section look ing in the direction of the arrow .2 in Fig.9. Fig. 1;? is a detail view showing means for regulating the feeding motion of the cutting or boring tool. Fig. 13 is a partly broken plan view of the devices for facing off the valve seat in the valve chest. Fig. 14 is a partly sectional side view thereof, and Figs. 15 and 16 are detail side views of the latter devices showing the direct application of the engine thereto.

In the accompanying drawings, in which 3 isjshown provided with a tool carrier 4 having a suitable tool 5, that is adapted to en gage and cut the inner wall 6 of the cylinder. (See Fig. 1.) Two tools 5 are shown on the carrier 4, but three or more may he used, and

the carrier 4 and tools 5 may be suitably ar- :5.

ranged to cut and true the interior of the cy inder. The shaft or spindle 3 is shown journaled in bearings 7 shown carried by suitable bracketsofy'okes 8, that are secured on the ends of the cylinder 2. The brackets or yokes are,or may be, secured on the ends of the cylinder 2 by screws of bolts 9 that may enter the holes that receive the screws for holding the cylinder heads in position. Bythis means the shaft or spindle 3 may be readily centered on the cylinder while the latter is in position on the locomotive and without necessitating its removal therefrom.

The shaft or spindle 3 is to be given a rotary, as well as longitudinal feeding, motion for the purpose of causing the cutter or tool to operate on the interior of the cylinder, and for this purpose I have as adapted to be connected with the cylinder 2 and to actuate said shaft or spindle. The engine 10, while it may be of any desired construction, is shown of the oscillating type, having a cylinder 10, mounted on trnnnions 11, carried by a suitable frame arranged to be supported by the cylinder 2. The said frame is made adjustable so that it may be applied to cylinders of dilferent dimensions. Said frame is shown constructed as follows:

12 is a yoke-like portion at the end ofone arm iuwhich a trunnion 11 of the cylinder 10 is journaied,the opposite member of said yoke having bolted to it the face plate 13 of the cylinder 10. jecting web or arm 14, shown extending at right angles so as to bear against the end of the cylinder 2, whereby it is supported. The web or 'arm 14 is shown in Fig. 8 as provided with a curved slot 15 that is-adapted to receive bolts or screws 16 that enter holes in the end of the cylinder 2, whereby said web or arm may be adjustably attached to said cylinder. By this means one end of the yoke 12 is conveniently attached to said cylinder, and it may be adjusted into the desired positions to bring the parts in proper positions on the cylinder. The trunnion 11 of the cy inder 10 is shown journaled in the plate 13, and provided with a tension spring 17 to hold the ports of the cylinder against the plate 13 in well known manner. The cross bar 12 of oke 12 is shown connected with the bent end 18 of a bar 18 by a bolt 18"., the bar 18 having a slot 19 to receive a bolt 19% that shown an engine 10,

The plate 13 carriesa pro-.-

passes into a similar slot 20 in abar 20. The bar 2O has a bent end 20 that fits against the end of the cylinder 2 by a bolt 20. By the foregoing construction the parts 14 and 20 can be secured to the respective ends of the cylinder 2, and the difference in lengths of different cylinders can be compensated for by means of the slots 19 and 20 and bolt 19. The yoke 12 is shown provided with bearings 21 in which is journaled a crank shaft 22 carrying pulleys 23, 24 at opposite ends. The piston rod 31 of the cylinder 10 connects with the crank 22 of shaft 22, whereby said shaft is turned.

The cylinder 10 may be supplied with steam or compressed air from the locomotive 1, or from anyother source, through a pipe 25, which may be provided with a suitable cook 26. For example, the air pipe 25, having the flexible connection 25", and coupling 25, can beconneoted to the valve 26 by the flexible section 26*, and thus supply the engine with compressed air. The steam supply pipe can likewise be connected; or an air or steam supply taken from any convenient source To conveniently supply the cylinder 10 with steam or air, and to permit the exhaust to take place I have shown the following arrangement: The plate 13 has exhaust holes 13 13 that are adapted to alternately align with ports 13, .13 in the cylinder 10 (see Figs. 3, 4 and 6) as the-cylinder oscillates. The ports 13 and 13 are also adapted to alternately align with ports 26, 27 in a bar 28 having a steam or air channel 29, the channel 29 communicating with the pipe 25, as in Fig. 6. The bar 28 is secured to the plate 13, and it is bent at 30 to permit the passage of the trunnion or pivot 11. With this arrangement as the cylinder 10 oscillates its ports 13,13 will alternately align with ports 26, 2.7 to receive steam and with holes 13", 13 to permit the exhaust to take place. 31 is the piston rod of cylinder 10" that connects with-the crank on shaft 22; but it willbe understood that any other desired arrangement of engine or means for operating the drive shaft 22 may be used.

The shaft 22 is designed to communicate rotary motion to the boring shaft or spindle 3, and for this purpose I have provided the following arrangement: At '32 is a frame or yoke shown supported at one end 33 by a standard 34, which may be secured on a tie, beam or flooring 35. (SeeFig. 1.) The standard or support 34 is shown "connected with the frame or yoke 32 by a bolt 36. The standard 34 is made vertically adjustable to regulate the height-of the frame or yoke 32 relatively to the shaft or spindle 3, and for this purpose said standard is'shown made in two parts 34, 34 the part 34 consisting of a yoke having a horizontal part 34 that receives the part 34", looking nuts 34 being used to hold the parts 34- and 34 together and also permit of their adjustment.

At the end 33 of frame or yoke 32 is jourso that said shaft or spindle-3 will be turned naled the hub 36 of a gear wheel 37, the shaft or spindle 3 passing through said hub as shown. The shaft 3 is keyed to the hub 36 by a spline and feather 37, 38, or otherwise,

by the hub 36, and yet have longitudinal movementtherein. The gear wheel 37 meshes with a. pinion 39 carried by a shaft 40 journaled on the frame 32, a spur wheel 41' on said shaft also mes-hing with a pinion 42 on a shaft 43 jonrnaled in the frame or yoke 32. The shaft 43 carries a bevel gear 44 that meshes with a similar, gear 45 on a shaft 46 journaled on the frame 32. The shaft 46 also carries a. pulley 47 that receives a belt 48 from the pulley 23, whereby the shaft 46 is turned. By the above arrangement of gearing the shaft 22 causes the shaft or spindle 3 to rotate, and at the desired speed according to the relation of the gearing; but it will be understood that any other suitable arrangement of device may be provided for turning the shaft or spindle 3 from the shaft 22, so long as the feature of adj ustably attaohingthe spindle 3 and an engine to the cylinder of a locomotive or engine is carried out.

The spindle or shaft 3 while rotatingshould be given a longitudinal feeding motion to advance the tool 5 to the work. I prefer to give the shaft 3 an intermittent longitudinal feeding motion, rather than a continuous feeding motion, and for this purposel have provided the following arrangement, which is clearly shown in Figs. 1, 9, .10, 11 and 12: One end of the shaft or spindle 3 is shown provided with a longitudinal bore 3, which receives a screw 50, stationarilysupported in any desired manner. For the purpose of conveniently attaching the screw 50 to the locomotive, in line with the axis of the cylinder 2, I connect said screw with a plate 51 that is clamped on the guide yoke or slotted plate 52 that receives the connecting rod of the locomotive. The plate 51 receives bolts 51 that pass into 3 corresponding plate 51 on the other side of the yoke, whereby the plates 51 and 51 maybe adj nstably held on the part 52.

53 is an internally threaded sleeve that travels on the screw 50, and it is provided with a spur wheel 5-1 whereby it may be turned to advance it along-said screw. Theshaft or spindle 3 carries a pawl that is adapted to engage the wheel 54 to turn the sleeve 53 and thus advance it along the screw 50 to move the shaft 3 longitudinally. The pawl 55 is shown carried by a spindle 56 journaled on a projection 57 carried on the shaft or spindle 3. The spindle 56 also carries a toe 58 that is acted upon by a spring 59 carried by the shaft 3 or its projection 57, whereby the pawl 55 is kept in engagement with the wheel-54:. To cause the sleeve 53 to be turned intermittently, to advance the shaft or spindle step by step, I permit the pawl 55 to be in engagement with the wheel 5% for a portion only of each turn of the shaftorspindle 3; or in other chest or box on the cylinder 2 si words the pawl 55 is lifted from the wheel 54;

after the latter has been turned, the desired distance during each revolution. For this purpose I provide a notched disk 60, upon which the pawl 55 can ride, and which is pref-' erably locatedbetween the end of the shaft 3 and sleeve 53, the screw 50 also passing freely through said disk; but the disk doesnot turn on said screw, being held from turningbya spline cutin the screw 50, and feather 61, 62, as shown in Fig. 9. The disk 60 is of about the diametenof the wheel 54, so that when the pawl 55 bears on said disk it will be held outof engagement with the teeth of the wheel 54. At this time the shaft or spindle 3 can turn without being advanced, but when the pawl 55reaches the notch 63 in the disk 60 it will encounter a tooth of the wheel 54 and thus turn said wheel and sleeve 53 to cause said sleeve, by being thus turned, to advance along the screw 50 to move the shaft 3 longitudinally a short distance. When the pawl 55 reaches the edge 64. of the notch 63 in the disk 60, it will ride up thereon and then bear upon the periphery ofsaid disk, being thus disengaged from the wheel 54, which comes to rest while the spindle 3 continues to turn. Thus an intermittent or step by step longitudinal movement is given to the sleeve 53 along the screw 50, the sleeve 53 moving the shaft or spindle 3 correspondingly, while it turns, to feed-the tool 5 to the work within the cylinder.

In order to regulate the amount of longitudinal movement given the spindle 3 at each revolution I cause the pawl 55 to engage the teeth of the wheel 54 sooner or later, with relation to the edge 64 of the disk 60. This can be accomplished by able plate 65 having its outer edge curved to follow the periphery of the disk 60, as in Figs. 10 and 12. This plate is shown provided witha slot 66, through which passes ascrew 67 that screws into the disk 60, a washer 6S acting to assist in holding the parts together in the proper positions. The pawl 55 is adapted to slide ofi from the end 69 of the plate 65, so as to engage the teeth of the wheel 54, and thus according to the distance between the points 6-1 and 69 the pawl 55 will give the wheel-5t more or less rotary motion. Therefore when it is desired to advance the tool 5 more,'the space between 6t and 69 is widened, and vice versa; but it is evident that the means for moving the spindle 3 longitudinally may be varied, if desired.

By means of my invention I ant also enmeans of an adjustabled to face all the valve seat of the valve multaneously with the truing of the cylinder, and I also utilize the same engine 10 to operate both sets of cutting tools. For this purpose I have shown a cutting-0r planing mechanism, the specific structure, however, not being my invention, I do not claim herein,as follows: 70 is the valve seat of the cylinder 2 outside of which, preferably at the corners of a rectangle, are'placed posts, standards or bolts 71,
