BERNHARD DREYER, OF SINDELFINGEN, GERMANY, ASSIGNOR OF ONE-- HALF TO EMIL KABISCH, OF SAME PLACE.
MACHINE FOR TURNING SHAFTING'.
SPECIFICATION forming part Of Letters Patent No. 672,872, dated Apri-1 23, 1901. Application filed May 3, 1900. Serial No. 15,330. (No model.)
To @ZZ whom it may concern: Be it known that I, BERNHARD DREYER, a
subject of the Emperor of Germany, residingat Sindelfingen, Bblingen, Kingdom of Wiir temberg, German-y,\have invented 'an Improvement in Machines feTurning Shafting, of which the following deslcxription, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
This invention relates to machines such as are adapted to turn a round bar or shaft; and the object of the invention is to provide means whereby the material is fed forward to a rotary cutter-head, the cutter-head carrying suitable tools which operate to turn the shaft or bar to the required diameter.
In the drawings, Figure lis an elevation of my improved machine. Fig. 2 is a detail showing a portion of the feeding mechanism. Fig. 3 is a vertical section on the line xm, Fig. 2. Fig. 4 is a view, partly in section, showing the means for supporting the turned shaft yas it emerges from the cutter-head. Fig. 5 is an end elevation of the device shown in Fig. 4. Fig. 6 is a partial sectional view of the cutter-head, showing the manner of keeping the shaft and tools cool. Fig. 7 is a section through the cutter-head on the line y y, Fig.y 6. Fig. 8 is a vertical section on the line .fr Fig. l; and Fig. 9 is a detail showing the handoperated means for operating the feed-rollers and looking in direction of arrow in Fig. 3.
Looking at Fig. 1, the bed or frame of the machine is designated by A, and this supports at its head end the rotary cutter-head 2, which is driven by the pulley 3 from any suitable drive-shaft, the said cutter-head carrying suitable tools for turning the shaft to the proper diameter, as will be hereinafter described.
Supported on the bed or frame in front of A the cutter-head is a feeding mechanism for feeding the material to be turned to the outter-head, the said material in this instance having only a longitudinal movement and the turning down of the shaft to the proper size being done by the rotary movement of the cutter-head.
I have'shown herein a pluralityof feeding devices operating in unison; but as they are both alike a description of one will suffice.
The said feeding device comprises a plurality of suitable standards 4, carried in any suitable way on the bed of the'frame A, the said standards each being slotted, as at 5, for the receptionof bearing-blocks 6, which support the shafts 8, said shafts carrying at one end the feed-rolls 7 and there being two such shafts and feed-rolls in each standard. On the opposite end of each shaft 8 from the feedroll is mounted a worm-gear i), the worm-gears on each standard meshing with and being driven by a vertically-arranged worm-shaft 10, supported in any suitable bearings on the said standard 4, each shaft 10 carrying at its lower end a worm-wheel 11, which in turn meshes with and is driven by a worm on the longitudinally arranged shaft 12, the said shaft l2 being driven by mechanism hereinafter described. As shown in the drawings, the shaft 12 is of sufficient length to drive'the feed-rolls of both of the standards 4, the said shaft finding its support in suitable bearings 14 on the bed of the frame. The shaft 12 carries at one end a gear 15, which meshes with gear 16, rotative with a shaft 17, said shaft being driven from the driving-pulley 3, through the gears 18 and 19.
In order to adapt the feeding mechanism for feeding different-sized work to the cutterhead, I have made the feed-rolls 7 adjustable toward and from each other, the said adjustvment being permitted by the bearings 6,-
which are capable of vertical movement in the slot 5 in the standard 4, as hereinafter described. The lower bearings 6 are positively adjusted by means of the bolt 20, (see Fig. 3,) the shank of which is screw-threaded and screws into anut 2l, carried by the standard 4. By turning the nut one way or the other the head of the bolt 2O can be raised or lowered, thereby raising or lowering the lower bearing 6, carrying the lower feed-roll 7. The bearings for the upper feed-roll are supported upon springs 22, said springs resting at their lower end upon the lower bearing 6 and supporting the upper' bearings. To yieldingly hold the two feed-rolls against the work, I have provided the springs 23, which rest upon the upper side of the upper bearing 6, and are controlled as to the amount of tension by the bolts 24, which are sustained in the upper end of the standard 4 and are screw-threaded IOO shaft to the correct diameter.
through nuts 25. The said nuts 25 are held against longitudinal movement in any suitable way and are provided on their peripheries with gear-teeth, which mesh with gear 26, and by turning the gear 26 by means of the hand-wheel 27 the nuts 25 can be turned to vary the amount of compression in the springs 23. The outer end of the shaft to be turned may be supported on any suitable supports 30, said supports being sustained on the bed of the machine and carrying at their upper ends friction-rolls.
In beginning the turning of any shaft it is necessary to determine whether the tools are set to turn the shaft to the right diameter, and in order to withdraw the shaft from the cutter-head after the turning operation has begun, so that the same can be calipered and its diameter determined, I have provided mechanism for reversing the direction of rotation of the feed-rolls 7, whereby after the shaft has been turned a short distance the shaft may be withdrawn and its size determined. The shaft 12 has fast thereon intermediate its length a bevel-gear 32, which meshes with a bevel-gear 33, fast on the shaft 34, said shaft being carried by the arm 35 and having at its end any suitable handwheel. The gear 16 can be disengaged from the shaft 17 by means of the clutch device 37, which consists of the clutch member 38, splined to the shaft 17, so as to rotate therewith, but have longitudinal movement thereon. A forked lever 39 engages said clutch member 38, the said lever being pivoted on an arm 42 and being operated by any suitable means-sueh, for instance, as by the gear 40, meshing with the segmental rack 4l on the end of lever 39, the said pinion being turned by a handle 90. By disconnecting the clutch 37 and by turning the hand-wheel on the shaft 34 it will be obvious that the feedrolls 7 can be turned in either direction by hand, and the shaft to be turned can thereby be withdrawn from the cutter-head, and the tools can be properly adjusted to turn the When the tools have been properly set so as to turn the shaft to the proper diameter, the clutch 37 is thrown into operation when the feeding of the shaft to the cutter-head will be accomplished automatically by the mechanism above described.
By arranging a plurality of feeding devices in aliuement I provide means whereby the shaft to be turned is positively held in the correct longitudinal position to be operated upon by the cutter-head, and by mounting the upper feed-roll yieldingly the shaft to be turned is automatically centered vertically during the turning operation.
My device is designed to turn each shaft throughout its full length,and therefore when the shaft has been advanced to the point where the unturned portion is about to leave the feeding device nearest the cutter-head it is necessary to provide some( mechanism for positively holding the shaft in the correct longitudinal alinement, and thisI accomplish by providing my device at the rear of the cutter-head with a suitable clamp,which compris'es two clamping-jaws 43 44, which are shaped to engage the turned shaft, as illus- (rated in Fig. 8, the said clamping-jaws being adjustable to and from each other by means of a shaft 45, having right and left screwthreaded portions which engage lugs on the clamping member, the said shaft being operated by a hand-wheel 49. The clamp is adjustably mounted in any suitable way on a guide 50, which extends from the frame of the machine. As illustrated in Fig. 8, each jaw 43 44 is grooved on its outside edge, so that when one side of said jaw becomes worn the jaw may be turned over and used again.
In using my device one shaft is inserted into the feed-rolls 7 and fed forward to the cutter-head, and as this shaft passes through and leaves the feed-rolls asecond shaft is inserted with its end abutting the end of the first-named shaft, and the two are simultaneously fed along, the second shaft operating to push the first shaft through the cutter-head, and the clamping-jaws 43 44 serving to hold the rst shaft from rotation as its end is turned to the propel' diameter.
In Fig. l, at C, I have illustrated the end of one shaft abutting against the forward end of the second shaft.' At the rear of the machine is a suitable support to receive the finished shaft after it has passed through the cutter-head, said support comprising the V- shaped member 5l, carrying the rolls 52. The said V-shaped member orguide 51 is vertically adjustable by means of the screw-threaded supports 54X, which are screw-threaded into the nuts 55X, supported on the uprights 62. Each nut 55X has gear-teeth on its periphery, and a shaft 57, extending the length of the support, has a suitable worm-gear thereon, which meshes with the teeth of the nuts 55X, the shaft 57 carrying at one end the handwheel 58, by means of which the said shaft can be turned and the V-shapedguide correspondingly raised or lowered. In order to discharge the finished shaft from the guide 5l,
I pivotally mount said guide on the supports 54X, whereby said guide may be turned about its apex to thereby allow the shaft to roll from the guide onto skids or other suitable iuclined surface and thence be carried to its storing-place. The guide 5l has suitable ears 59, which are fast on the pivot-shaft Gl, the said shaft being supported for turning movement in eyes in the upper end of the screwthreaded supports 54X. The said shaft has fast thereon the segment 67, carrying on its periphery teeth which mesh with worm on the shaft 68, which shaft may be operated by the hand-wheel 70. By turning the shaft 68 it will be evident that the support 5l can be turned about its pivot 6l and the shaft discharged therefrom.
As illustrated in this application, my inseveral jets.
vention comprises a machine having a single rotary cutter-head carrying tools which are adapted to' rough-turn and finish or polish the shaft at one operation, so that all of the turning or work upon the shaft is done at a single point, and for this purpose the cutterhead carries a series of suitable tools b' to operate on the shaft being turned, the said tools being supported in the cutter-head in any suitable way and being arranged obliquely to the shaft being turned, and in order to perform the operations above described I preferably employ a series of such tools, which are spaced at approximately equal distances apart, so as to bear against the shaft upon all sides thereof, thus preventing the shaft from springing or yielding during the turning operation. In order totkeep the tools and the shaft cool during the turning operation, I provide mechanism whereby several streams of water are constantly thrown on the tools and shaft. On the sleeve of the cutter-head a ring c is fixed, in the periphery of which is a' groove d, from which groove extend channels e through the cutter-head, the said channels emerging at the point where the tool operates upon the work. The ring chas at each side beveled flanges c', and surrounding said ring and fitting between the bevel-flanges is a second ring f, which is held against rotary movement by means of the arm f', integral therewith and depending therefrom, said arm engaging at its lower end suitable lugs or stops on the bed of the machine. The inside of the ringf has a channel h, which when the ring is in place coincides with the channel d in the ring c, and said ring f has a duct g, which communicates with any suitable source of water-supply and through which the water is fed to the channel From this construction it will be readily seen that as the cutter-head rotates the ring c rotates inside of the ring f, and the water which is supplied through the duct g finds its way into the channel h and from thence into the channels e, which conduct the water to the tools and shaft, the water being thrown on the shaft in The bore of the cutter-head is slightly enlarged at the point where the channels e lead into the same, and in said enlarged bore is a ring t', the said ring being perforated and being adjustable lengthwise of the cutter-head, the ring serving to prevent the chips from entering the channels e.
The invention is not limited in all of its details to the precise construction herein set forth, but may be varied in many details within the scope of the appended claims.
