AUTOMATIC LATHE FOR WORKlNG PIPES OH BARS.
Specification of Letters Patent.
Patented March 5, 1907.
Application filed December 2S, 1903. Serial No. 188.290.
To all whom it may concern.-
Be it known that I, ARTHUR H. Binnie BURN, a subject of the King of Great Britain, 9
residing at Matteawan, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Automatic Lathes for \Vorking P'pcs or Bars, of which the following is e specifiers tion, reference being: bad to the drawing sc-- com ienymg and forming part of the some.
T e Ob ect of my present invention is to provide a machine for machining the ends ol' a. pipe or bar which shall be autonmtic in its operation after the object to be worked has been placed in the machine, H
In the embodiment herein specifically shown the sp eratus is designed to turn both ends of t e object down to any predetermined size simultaneously and to cut oil' both ends, whereby the pipes or hers will be delivered all of the some length and finish.
The invention itself, however, consists in the novel features and combirnitions hereinafter described, and. more particularly pointed out in the claims.
Referring to the accompanying; drawings, Figure 1 shows the machine in side elevation. Fig. 2 is a plan View of the same with the work-holding devices in section. Fig. 3 is a View in elevation of the side opposite to that of Fig. 1, showing part of the machine in the tail. Fi s. 4 and 5 are sections on lines IV 1V and V t respectively, of Fig. 3 looking in the directions of the arrows. Figs. 6, 7, 8, and 9 are detail views of certain parts of the mechanism.
The object to be worked, which in. the present instance is shown to be a. pipe, is indicated by 1. it is hold in a carrier consisting of sleeves 2 3, Fig. 2, mounted to rotate in suitable bearings, as 4 5. Each sleeve can rise a. chuck 6 7, preferably of the soii-centen ing type, so that the pipe is firmly held at each end. The carrier is rotated through the gear 8 by engagement with e pinion 9 on the counter-shaf t, which carries 9. gear 10, driven by the pinion 11 on the power-shei t 12, hav ing sorivingpulley 13.
The turning-tools 14 15 and the eutlingmif l tools 16 1'7, Fig. 2, are held in suitable hold ers,es shown, mounted over the rock-shafts 18 19. The transverse motion of the tools to cause them to bear on the pipe is ell'ectod by means of gear-arms, as 20 21, on therockshafts, which engage racks, as 22 23 on the tool-slides. flliiviously, if the rock-shafts be oscillated the tools will be carried inward ug ninst the work. To rock the shnl'ts, 1 provide the shaft 18 with an arm '24- end shnft 19 with an arm 25, having studs 26 27 working in coins 29, from which it will be seen this rotation of the latter will rock the shsl'ts 38 it).
A. scraper, as 17 Fig. 4, may also be provided, in connection with ouch cutting-off tool, on the tool-carriers, as shown, so as to hear on the pipe, alter the end has been cut oil, to give the smile a final iinish or to remove any irregularities which may be left by the lurningytools l -i. 15.
To reciprocate the turning-tools lengthwise ol' the work, l provide drums 30 31, preferably located between the first-mentioned reins, as shown, heving' spiml cunngrooves in which work studs 32 I53 on cross-heads 34 35, connected to links 36 37, which are in turn connected to the tool-carriers 38 39, so that rotation of the cn1n-dru1ns will move the tools 14 3:3 in the desired manner.
The minis are rotated by engagement of the gem 30 with a worm +11 one shaft 12,
which has a. gear 43, driven by a. gear 44.'
which lmlier driven by gears 46. Gear 4i; is carried by a muntensheit 4.7, having a sprocket-wheel -18, connected by a, chain passing under an id ler 49 on the i-ocli-shei t 18 to n sprocket o0, rotatably mounted on the power-shaft 12. The sprocket 50 abuts against the hub 51 of the driving-pulley 13. Both sprocket and hub have holes correspending to the pins 52, which are rotatably carried by s. spring-actuated push-bar 53, so that when the latter is pushed. in the pins will be carried into the openings in the pulley hub and so connect the sprocket 50 rigidly therewith. in this position the bar is engaged and. held by s sliding, latch 54. The sprocket is thus rotated and drives the cams which reci rocnte the tool -slidcs. If the hitch 54 is disengaged from the bar, the litttfll is instantly retracted by the spring 55 end the sprocket 50, no longer com'iected with the pmver-prd-ley, ceases to be rotated.
it may sometimes happen that by reason of weer or the tools becoming loosened the pipe may not be reduced to the proper size or not entirely out through, by i re cutting oil too], or both, when the operation of the machine is com )leiwl, and it is therefore necessary to reworlr the ipe. in. order to bring the tools back to the starting-point quickly, I provide rhainuellyi is wretcd means for shi ting the same to any position. A convenient method for this purpose is to adapt an end 56 of shaft 12 to be engaged by a crank, (not shown) and in order to permit manual rotationof'thc shaft 42, and with it the cams, I mount the mechanisi'n which drives the shaft in such a manner that the two may be disengaged at will. For example, as shown in Figs. 3, 6, and 7, the hanger 57, in which rofates the arbor carrying gears 44 and 45, is revolubly' mounted on the shaft 47 in the brackets 58 59, so that it can drop down to the position shown in dotted lines in Fig. 7, carrying the gear 44 out of engagement with the gear 43. The shaft 42 may then. be
means, said cam devices having a pair of rapidly revolved by means of the crank,]
causing the tools to move quickly to any desired position To hold the hanger 57 in raised position, so that the gears 43 and 44 will be in mesh, an arm 60 is provided on the hanger, carrying a pivoted stop 61, Fig. 7, which holds tion shown and the gears therefore in mesh but by swinging the stop 61 downward or fipward the arm can tilt forward and so disengage the gears.
The operation of the machine will be readily understood from the foregoing. It automatically dresses the ends of the pipe or bar and automatically cuts ofl a portion, leaving the pipe or bar the desired length and its ends of the desired diameter. The timing of the operations relative to each other depends, of course, upon the arrangement of the cams relative to each other, so that by properly tying them the operations in ay occur ins sion or simultaneously.
The extentof the operations that is, the extent of movement ot' the toolsdcpends upon the proportions of the cams and other operative parts, and these also maybe varied to any desired degree without departing from the spirit oi the irmention.
It should be further understood that the machine herein specifically shown and de scribed is only one oi the many embodiments of which the invcl'ition is capable.
What I claim is- I. In a machine of the kind described, the combination with means for holding a pipe with the end thereof exposed, and means for rotating the said pipe-holding means, of toolcarriers arranged adjacent to the positions occupied by the exposed ends pf the pi e and adapted to 'be reciproeated llongitut inally thereof, a earn-shaft parallel with the said I r n pipe-holding means, cam devices on the shaft,
ocated between the ends of the pipe-holding I I I I I I I I I peripheral ram-grooves, cross-heads adjacent to the cam devices, having studs engaging the peripheral grooves therein, and links,
connecting the cross-heads with the respective toobcarriers, whereby the rotation of the cam devices will reciprocate the toolcarriers ,substantiall y as described and for the purposes set forth.
