BORING-MACHINE.
SPECIFICATION forming part of Letters Patent No. 446,792, dated February I17, 1891.
Application filed March 14, 1890. Serial No.3431875. (No model.)
. ings, forming a part of the same.
This invention relates to improvements in that class of cylinder-boring machines in which the work to 'be operated upon is strapped or-otherwise secured to a carriage having a sliding connection to the bed-plate of the machine, upon which carriage the Work is fed as the boring progresses toward the boring-cutters carried by spindles mounted to revolve on a head-stock at one end of the machine, said spindles and carriage being connected usually to the same power-shaft-4 ing and so timed in their movements relatively to each other as to secure the proper feed of the Work to the cutters. lVhen in these machines provision is made for facing the edges of the cylinder, the operation of facing must necessarily follow the boring operation, and the method used consists of detachable cutter-heads placed, after the boring operation is concluded, in the boring-spindles, from which the boring cutter-heads (which are also detachable) have been removed forthe purpose. This substitution of the facing cutter-heads for the boring cutter heads, and vice versa, requires a readjustment of the Work to be faced or bored, and if both ends of the cylinder are to be faced a resetting of the cylinder is necessary. These adjustments of course entail considerable labor, as they must be accurately made, and they also consume considerable time. y
lt is the object of the present invention to simplifythe construction of these machines and to provide an organization in which but one setting and adjustment of the Work and boring and facing cutters for all the operations will be required and which can be performed Within the time ordinarily consumed in the setting and adjustment of the same for one of the operations.
It is also the obj ect of the present invention to provide a Inachine having an increased acrevoluble and sliding connection to the bedo plate of the machine and means for locking said table or platen in adjusted positions during the operations of boring and facing; third, a movable head-stock provided with a spindle or spindles carrying facing-cutters and capable of simultaneous operation with the boringspindles, but upon the opposite end of the work operated upon, so that the two operations of boring and facing can be performed at the same time and With a single adjustment of the work and cutters; fourth, a facing-spindle consisting of a hollow sleeve mounted to turn in its head-stock and provided upon its interior with suitable bushings for receiving a bar extending through the same, connected to the boring-spindle, and carrying the cutter-head for supporting the latter When the cylinder to be operated upon is of a length exceeding the length of the overhanging portion of the spindle; fifth, devices for automatically feeding the facingcutters and means for reversing the direction of feed.
As a full understanding of the improvements of the present invention can only be had from a detailed description of the same, such description will now be given,reference 4being had to the accompanying drawings, in
Which- Figure l is a side elevation of aboring-machine constructed according to the present invention. Fig. 2 is a longitudinal sectional elevation of the same, illustrating more particularly the construction and arrangement of the driving mechanism for operating the spindles. Fig. 3 is a section of the same, taken on the line 3 of Fig. 2; and Fig. at is a similar view taken on the irregular line 4 of Fig. 2. Fig. 5 is a horizontal section on the line 5 of IOO Fig. 2, illustrating the construction ot the revolving platen for receiving the work to be operated upon. Fig. G is a view illustrating the feeding devices of the facing-cutters- Referring to said drawings, it will be seen that the machine therein illustrated is provided with a head-stock l anda pairot spindles for the boring cutter-heads 3 and cntters t and with a head-stock 5 and pair ot spindles 0 and cutter-heads 7 for the facingcutters S, these two boring and facing headstocks being arranged at opposite ends of the machine. The head-stock lis supported at the proper heighten legs orpedestals t), bolted to the bed-plate l0 in substantially the usual way. It is provided with a pair of spindles 2, journaled so as to revolvein the head-stock i, as shown, a suitable bushing composed, preferably, of a brass sleeve l2 and a ring 11, of soft metal, being interposed between the parts to reduce the friction and consequent wear.
In the machine illustrated in the drawings two sets of boring and facing instrumentalities are illustrated. These two sets are provided for the purpose of doubling the working capacity of the machine. Both sets being, however, exact duplicates in construction, a description ot the one set will be sut'iicient for an understanding ot the two, and such description will new be given. Each spindle 2 is n'ovided at its end overhann'ine' the.
bed-plate lO with a tapered hole for receiving the correspondingly-shaped end of the cutterhead 3, which islocked tothe spindle by means of a key 13. The cutter-head 3 is provided with the usual cutters l, arranged at suitable intervals in its tace. 'lhe spindles and cutterheads receive their motion through suitable connections with the power-shatting. Those shown in the present case consist ot gears ll, one for each spindle 2, both ot which mesh with a common pinion l5 011 a shaft 17, supported in bearings in the legs E), and abrackct 18, extending from the machine, which shatt also carries a gear-wheel 19, meshing with a pinion 1G, carried on the inner end of a shaft mounted in the bracket 1S, and having at its opposite end a pulley E20, which receives motion from the usual belt or apron. (Not shown.) The mechanism just described constitutes the means provided for the rotation of the spindles 2. lt will be observed that the spindles are both geared alike and to a common shaft 17, and that as a result they are both driven simultaneously and at a uniform speed.
Mounted on the bed-plate l0, so as to be capable ot sliding longitudinally thereon to and from the head-stock l, is a carriage 2l, having on each of its sides a flange 22, engaging the edges of the bed-plate, as shown best in Figs. 3 and t. The carriage 2l, at its end portion next the head-stock l, has mounted upon or formed integrally with it a plate 23, Fig. 3, having a central annular opening 24e, into which projects a correspondinglyshaped .flange 25, termed in the under side of a platen or table 2G l'or supporting the work to be operated upon, which, as shown in Fig. v1, consists ot an ordinary pumping-engine cylinder C. The base el. the table 2U, as shown in the present case, is circular in horizontal section (see Fig. 5) and is provided with an annular' groove 27, with which engages a series of nuts 28, oppositely arranged and screw-threaded upon their interiors for engagement with the correspondingly-threaded ends ol. rods Q9, mounted in the plate 25S. The ends ot each ot these rods are provided with right and lett hand serewthreads, so that upon the turning of the rod both the nuts will be moved into or out ot contact; with the groove 27. rlhe purpose of these nuts is to securely hold the table to the plate against the tendency to rise during the cutting operation of the boring-cutter Li upon the cylinder C. It will be seen that the connection between the table 2b andthe plate 23 is such as to permit the rotation ofthe former upon the latter when desired, so as to permit the turning of the cylinder C from the position of parallelism to the spindles 2, in which it is shown, to an angular position thereto, or end for end.
Provision is made in the present case for preventing the rotation ol the platen or table 2G, preferably at predetermined points in its rotation, consisting ot' a series of openings 30, Fig. 5, in the base of the table lti and a pin 3l, Fig. 5, passing through the plate 23 and held normally in a raised position by a spring 32, Fig. l, secured to the carriage 21. Means are also provided for the withdrawal of the pin from the openings 30, consisting of a rod 33, capable of being slid horizontally on the carriage 2l by means of a handle Si, the tapered end ot. the rod passing through an opening provided in the power end of the pin 3l, as shown in Figs. 2 and El. But four ot these openings S0 are shown in the present case, as ordinarily this number will be found snfcient for all purposes, providing, as they do, l'or an end-for-end movement or a quarterturn in either direction of the cylinder C and the table 2G, these four openings being so located that upon the completion ot a quarter of a revolution of the platen or table the spring-pressed pin 3l, unless held depressed by the rod 33, will enter the opening at the iirst quarter and prevent the further movement ot the carriage. To permita half-turn of the table, the pin will be held depressed until the opening at the first quarter has passed, the pin then engaging the opening at the next quarter. Any number et openings may be employed for the purpose, so located as to lock the table against rotation in other desired positions.
The carriage 2l is provided with means whereby during the operation of the boringspindles it is slid on the bed-plate l0 toward the boring head-stock l. The means provided in the present case consists of a rack IOO IIO
35 upon the under side of the carriage, engaging a pinion 3G, keyed to a shaft 37, journaled in the frame of the machine and transversely thereof, as shown in Fig. The outer end of the shaft 37 has keyed to it a sleeve 3S, capable of a slight longitudinal movement on said shaft and provided with hand-spokes 39 for the operation by hand of the shaft 37 and pinion 36 to slide the carriage 2l to and from the head-stock, and
thus bring the cylinder C into or out of position to be operated upon. The shaft 37 has also loosely mounted on it aworm-wheel 40, which is engaged by a worm 4l carried on one end of a longitudinal shaft 42, journaled in the side ofthe frame of the machine. The opposite end of the shaft 42 is connected by gears 47 48 49 50 with a shaft carrying a pulley 46, conneetedby a belt 44 and pulley 45 to the shaft 17, which, as before explained, receives its motion from the pulley'20. The gears connecting the shaft 42 and pulley 46 are so proportioned relatively to those connecting the spindles 2 to the pulley 2O as to secure a slow movement of the carriage 2l toward the head-stock l and a correspondingly slow feed of the work tothe cutters 4 relatively to the rotation of the spindles 2 in the usual manner. The shafts 42, Fig. l, and 37, Fig. 3, when out of engagement permit the shaft 37 to be operated by hand to move the carriage forward or backward to adjust the work to proper position with relation to the cutters 4. The edges of theinner face of the sleeve 38,Fig. 3, are, as shown, beveled, and the outer face of the worm-wheel 49 is correspondingly recessed. Then the faces of the sleeve 38 and wheel 40 are out of contact, as shown, the sleeve and its shaft are not affected by the movement of the shat't 42. lVlien, however, it isdesired to couple the shafts 37 and 42 and thus cause the carriage 2l to be operated from the pulley 20, it can readily be done by bringing the adjacent faces of the'sleeve and worm-wheel into frictional contact with each other by turning a screw 43 upon the end of the shaft and forcing the sleeve 38 against the wheel 40.
`rlhen sufficient friction will exist between the two to couple the shafts 37 and 42, and the movement of the latter will be communicated to the former and, through the rack 35 and pinion 36, slide the carriage 2l toward the boring head-stock l and feed the work upon the table to the cutters 4.
The operation of the machine as thus far described is as follows: The work to be operated upon, consisting, as herein shown, of the cylinder C of an ordinary pumping-engine, is first properly adjusted and set in the usual manner upon the table 26, which is prevented from revolving upon the plate 23 by the engagement of the pin 3iwith one of the openings 30, as shown in Figs. 2 and 3. By then turning the rods 29 in the plate 23 the nuts 28 are forced within the groove 27 in the platen or. table 23 and tightened against the same and caused to bind against the side of the table with sufficient force to lock the table securely to plate and prevent it rising therefrom. The carriage 2l, and with it the cylinder O, is then moved to or from the headstock l, as the case may be, until the cylinder C is properly presented to the cutters 4, this movement of the carriage being accomplished by turning the sleeve 38 (which is out of contact with the wheel 40) and shaft 37 and pinion 3G, which latter, engaging the ratchet 35, will move the carriage back or forth, as before explained. The shafts 37 and 42 being then coupled, as before explained, and the spindles 2 and cutters 4 being set in operation, the shaft 37 and its pinion will through the connections before described be correspondingly rotated, but at a slower rate of speed, and caused to advance the carriage 2l and the cylinder C toward the head-stoek` as the boring continues. rlhe carriage 2l will continue to advance as long as the spindles operate and while the shafts 37, Fig. 3, and 42, Fig. l, remain coupled.l Then it is desired to stop the movement of the carriage by the power-shafting, it can readily be done by loosening the screw 43 upon the shaft 37, when, the friction between the sleeve 38 and wornrwheel 40 being removed, the shafts 37 and 42 will be uncoupled. The carriage 2l can then be moved in either direction, as desired, by the hand of the operator. rlhe shaft 42 is split in the usual way to provide for the breaking of the connection between the powershafting and the driving mechanism of the sliding carriage 2l when desired. The means provided in the present machine for making and breaking this connection consists of an ordinary hand-wheel 75, Fig. l, by turning which in one direction the adjoining ends of the shaft 42 are united, the wheel 75 upon being turned in the opposite direction disuniting theends. lf it is desired to adjust the cylinder C so as to have the cutters operate at right angles to its axis, the rods 29 will be turned in the proper direction to loosen the screws 28 and the rod 33 shoved forward, so as to withdraw the pin 3l from the opening 3U, with which it is then in engagement. The table 26 being then turned to the right or left, as the case may be, upon the completion of a quarter-turn of the same the pin 3l will enter the next of the series of openings 30, when the cylinder will be in a position at right angles to its former position. The rods 29 being then turned, so as to tighten the nut-s 28 about the table 26, the cylinder C will be ready for adjustment to or from the cut-ters 4 by means of the hand-wheel or sleeve 38 in the manner just described. To turn the cylinder end for end, the table 26 will be given a half-turn, the pin 3l passing one of the openings 30 and entering the next of the series of openings. lf desired, the work may be fed to the cutters 4 as the boring progresses by operating the shaft 37 and its pinion 36 by hand, the connections with the power-shafting being thus dispensed with. It will be IOO IIO
preferable, however, to have the work fed to the cutters from the power-shafting, as described, as the feed in that case will be more uniform.
Referring now particularly to Figs. l, 2,
and 1, the construction and arrangement of the facing mechanism will be described. The facing head-stock 5 is mountedupon the carriage 2l, its base being dovetailed in the earriage, so as to be adapted to slide thereon to and from the cylinder C. The carriage 21 is provided with a rack 50, along which travels a pinion 5l, mounted on the end of a shaft 52, journaled in the base of the head-stock 5, the opposite end of said shaft being provided with hand-spokes 58, by which it is turned to cause the head-stock 5 to move back an d forth en the carriage for the positioningr of its cutters S out of or into contact with the cylinder C. It will thus be seen that the head-stock 5 being mounted on the carriage 2l has a movement therewith during the feed of the cylinder to the boring-cutters 4, so as to retain its 0pcrative position with relation to the cylinder, and has also a movement thereon independent thereof for adjustment with relation to cylinders varying in length. The head-stock 5 is also provided with means by which it is locked to the carriage 2l after adjustment into or out of operative position with relation to the work to be operated upon. The means illustrated in the present case consists of bolts SO, passing` through the base of the head-stock and enteringa sliding blockSl. (See Fig. et.) During the adjustment of the head-stoel; 5 the bolts SO will be loosened, so as to permit the block Sl to be slid along the table 21; but when the head-stock has been adjusted to proper position with relation to the work to be operated upon it will be held therein by tightening the bolts S0, thus causingthe block Sl to bind against the inclined edge of the table l.. The head-stock 5 is provided with a pair of hollow spindles tl, each mounted to turn in a sleeve 5t, interposed between the head-stock and the spindle 4 to lessen the wear of the parts. Each of the spindles is provided at its inner end with a cutter-head 7, having a screw-threaded connection to the spindle, (though the connection may be any other.) so as to revolve with the spindle. The cutter-head 7 is providedin its outerfaee with a vertical channel 55, in which is located a sliding block 56, having a vertical screwthreaded opening, with which engages a feeding-screw 5T, mounted in a lug or projection 58 in the upper end of the cutter-head 7, as best shown in Fig. 2. The facing-cutter S is carried in one end of a bolt 59, which passes through the slide 5U, and is provided at its other end with a tightening-nut (50, Fig. 4. The spindles G receive their motion through connections similar to those of the boringspindles 2, consisting of gears let, (one for each spindle (5,) meshing with a common pinion l5, keyed to a shaft 1T, connected by gear 151 and pinion 1U with the shaft of a pulley 20, corresponding to that numbered 2t) at the other end of the machine, liig. l. The several gears at both ends of the machine are ot equal diameter, respectively, and
the pulleys 2O 20" being driven at the same speed it follows that the facing and boring spindles are driven at the same or substantially the same speed of rotation. The two sets of spindles, however, being driven independentlyof each other, it follows that either set may be thrown out of operation without affecting the movement of the other.
The operation ofthe facing-cutters will now be described. The cylinder C having been adjusted to proper position with relation to the boring-cutters ft, as before described, (the facing head-stock moving with the carriage 2l in this adjustment,) the facing-cutter 8 will be brought into contact with the opposite end of the cylinder C by having the forward movement of its head-stock upon the carriage, the shaft 52 and pinion 5l being turned by hand, as before described. This may he done either during the rotation of the facing-spindles (3 or before movement has been imparted to them. lVith the facing-cutters S thus posi` tioned and locked by means of bolts 80, upon movement being imparted to thc pulleys 2() 20 the spindles L (5 will both be rotated and the two operations of boring and facing performed simultaneously, but at opposite ends of the cylinder. Then the respective ends have been bored and faced,the cylinder C will be turned end for end in the manner before described and the operations repeated upon the opposite ends ofthe cylinder, unless the boring operation has been completed in the first instance, in which case the facing operation alone will be performed upon the opposite end of the cylinder.
It should be noted that the gear lil", Fig. l, is feathered or splincd to the shaft 17, which is extended, as shown, and which is itself loose within its bearings in the bracket 1S, the gear lll being thus capable of longitudinal movement on its shaft and the latter capable of longitudinal movement in its bearings, thus permitting the backward and forward movement of the head-stock 5 with the carriage 2l and independently thereof without disconnection from its driving mechanism.
'lhe boring and facing spindles, instead of having independent power mechanisms, as described, may, if desired, be driven from a common power mechanism, the boring and facingspindles being, preferably, in such case provided with beltshifters or other suitable devices for bringing either or both into or throwing them out of operation when desired.
Provision is made in the present machine for the feeding of the cutters 8 during the rotation of their spindles to different positions with relation to the work operated upon, the mechanism for this purpose shown in the drawings providing for three different feeds of these cutters and in either of two direc- IOO IIO
tions. rlhis mechanism consists of a series of feeders or pins (il 62 G3 fr each of the cntters mounted in the outer end of an upwardly-extending arm 64, secured to the headstock 5. (See Fig. l.) These feeders or pins are held normally in their raised positions by springs 65 and are brought to their depressed position for contact with projections or points 6G, formed upon the heads of the screws 57, (see Figs. 2 and 6,) by an adjuster so positioned as to engage the feeders or pins G1, &c., of each cutter-feeding device, which are thus rendered simultaneously adjustable, the movement of the adjuster simultaneously moving the different feeders into or out of position for engaging and operating their respective feeding devices. As shown in the drawings, this adjuster (see Fig. (3) consists of a sliding rod 68, common to bo'th sets of feeders or pins Gl, the., having cams '67, engaging shoulders formed in the feeders or pins. The rod GS slides between guides G9 on the arms G-i, in which it is held by a plate 70. It is to be understood, however, that the present invention broadly includes any other form of adjuster performing the function of sim ultaneously adjusting a plurality of feeding devices.
The feeding operation is as follows: Suppose the parts to be in the positions in which they are shown in Fig. 4, with the pin 6l of each series depressed for engagement with the points 6G on the heads of their respective screws 57, the spindles 6 movingin the direction of the arrow in said ligure. As each spindle 6 and cutter S complete a revolution and the cutter approaches the position in which it is shown in Fig. 4, one of the points G6 on the head of the screw 57 is engaged by the pin 61, in passing which the screw is turned so as to raise the slide 56 and cutter S slightly, and the latter in its next revolution is caused to describe a circle having a diameter slightly in excess of that described in its previous revolution. This feed will continue until the facing operat-ion is completed or until the pin Gl-is raised. To increase the feed, two of the pins Gl 62 will be depressed, when the screw will be turned twice the distance, and by depressing the three pins 0l 62 (53 this distance is trebled. To provide for the downward feed of the cutters 8, each of the armste is provided with a slot 7l in its base, in which is located a setscrew 72, by which the arm is secured to t-he head-stock 5. By loosening this screw the arm (54 may be moved outward, so that its pins will engage the points 66 upon the opposite side of the aXis of the nut 57, when the nut and cutter will be moved in a direction contrary to that just described-. c., in a downward direction. Each of the spindles G is provided at each end upon its interior with a bushing 7 3, of soft metal or other suitable substance, for receiving and supporting the rear end of a rod 7a for supporting the boring cutterhead when operating upon a cylinder the length of which exceeds that of the overhanging portion of its spindle 2. The forward end of this rod is keyed or otherwise connected to the boring-spindle, as shown in 2, and is provided with a spline or feather 76, engaging a correspondin gl y-shaped recess upon the interior ol the cutter-head E3, along which the cutter-head El can be moved for adjustment with relation to work to be operated upon and by which it is held from rotation upon the rod 7 i. The cutter-head 3 is also provided with set-screws S2 for locking the cutter-head to the rod 76 after the same has been adjusted to desired positions.
