Application filed April 12, 1926. Serial No. 101,411.
My invention relates to means for applytioned on the bed are bearings 3 carrying a ingandremovingcouplings and the like to supporting means for a pipe 4, and means and "from pipes and the likeand its general for rotating said pipein said supporting object is to provide a device of this character means. The pipe is shown as belng'ipro- 5o 5 that cooperates with a metalworking lathe. vided with a coupling 5 which is threaded The primary objectof my invention is to on one end. t provide a simpleand eil'ectivemeans for In many cases the coupling has become holding a coupling commonly used for conrustedto the pipe and is difiicult to remove necting pipe lines, from rotating when retherefrom, and also to place the couplings 60 moval or application thereof from and to a thereon, should the threads on thercoupling pipe is required. and the pipe be rusted or mutilated. In
A further object of my invention is to such cases it is impossible to use ordinary provide an auxiliary chuck that easily Standard pipe tongs that are manually opercentered and can be expeditiously associated ated, therefore I have provided an auxiliary 65 ith th u ling, A centering chuck it comprising a jaw 6 I ivot-i A still further object of my invention is ally carried on standards 7 as at A. X jaw to provide ad'ustablemeansfor attaching 8 has one end pivotallysecured to one end t h k to t 8 li I of thejaw 6 asat 9 and the free ends of Another object of my invention is to prothese jaws cooperate and. are 1 designed for 70 vide a counter-balancing means for assisting registratlon as at B. The jaw 8 is pro-,
in opening the jaws of the chuck. vided with an outwardly extending lip C These and other objects will hereinafter be which 15 adapted for receiving a yoke lOi'or more fully explained. a a purpose hereinafter described. Rockably Referring to the drawings: mounted on the jaw 6 is the yoke 10 which 175 Figure 1 is a side elevation of a lathe is operated throughthe'medium of a pivotadapted for threading pipes, and illustrates ally connected yoke 11-and is adapted tofl the application of the device forming the rock in the direction indicated by thearrow subject matter of the present invention D; the said yoke 10 having an aperture 11in thereto. each end thereof to receive the bosses. E on so Figure 2 is a top plan view thereof. the ends of the arms of said yoke 11;the Figure 3 is a side view of my device said yoke 11 having a handle}? centrally per e, positioned thereon for operating the same.
Figure 4: is a view taken at right angles The yokes are pivoted to the jaw 6 bypins to Figure 3 and illustrates one edgeof the 12 eccentrically mounted in thebosses and s5 device. when the yoke 11 is rocked upwardly as Figure 5 is a similar view of the opposite indicated by arrow G, the yoke 10 willlreedge. leaseits tension onthelip C, then by rock-; Figure 6 is an enlarged detailview of the ing yoke 10 outwardly as indicated by arrow locking means for the jaws. D, the jaw 8 will swing u wardly' and rear 90 Figure 7 is asimilar view showing the wardly as indicated by otted lines H in position of the lever for the locking means Fig. 3. when the jaws are in locked position. As a convenient means for raising the Figure 8 is a fragmentary sectional view upper jaw I have provided a counter weight taken approximately on line 88 of Fig- 13 suspended by a cable 14 which is attached 95 ure 6, looking in the direction of the arrows to said jaw 13 as shown at I and travels on Figure 9 is a side elevation I of the eca sheave 15 whichis rotatably mounted becentric carrying means for the standards 'tween the ends of arms 16; said arms being Figure 10 is a view taken at right angles rigidly attached to one of the standards as toFigure 9. shown. On jaws 6 and 8 are radiallyp'osi- 100 In Figures 1 and 2 is shown a lathe bed tioned substantially U-shapedframes 17 hav- 1 supported by legs 2. Vertically posi ing their arms slidably engaging in dove;
The standards 7 are composed of two parts, the lower parts being indicated by the bearings trunnioned on rollers 23; the said rollers being rotated by a shaft 24 which eccentrlcally positioned therein as shown in 'Fig. 9, and the ends thereof are rotatably mounted in bearings 25 which are rigidly attached to the floor. On the outwardly extending end of the shaft is a lever 26 rigidly attached thereto, and by rocking said lever the chuck is raised or lowered. WVhen rocked in the direction as indicated by arrow J the standard will travel in the direction indicated by arrow K; this rocking movement is necessary when the lathe is removing the coupling for the reason that the travel of the coupling horizontally will carry with it the chuck rocking the standards out of their vertical positions, and in order that the chuck may travel horizontally with the coupling the eccentric must be turned simultaneously with the travel thereof for supplying the defieieney of the standards length as the coupling is removed. It will also be understood that the eccentric feature is employed when a vertical movement is required to center the chuck on the coupling.
As a means for vertically supporting the standards I have provided springs 27 which have one'of their ends attached to the floor and their opposite ends secured tothe standards as at L; the said springs will normally retain the chuck in an upright position and allow the standards to rock while the chuck is being carried horizontally by the threaded action of the coupling.
From the above description and disclosure of the drawings, it will be obvious that I have provided a novel device for removing and applying couplings, joints and the like from and to pipes and the like, in an easy and expeditious manner with very little effort and in the operation of the device, when it is desired to remove'the coupling from the pipe as shown, the pipe is mounted in the bearings 3 and the jaws are secured inapplied position with the teeth in biting engagement with the coupling, the lathe is then put into operation for rotating the pipe lathe for applying and removing pipe couplings, eomprismg a pair of arcuate shape jaws pivotally connected together at one end, a plurality of frames radially positioned on said jaws, toothed, members carried by said frames, screw means for adjusting the frames, a clamping means for securing said jaws in closed position, a pair of standards pivotally engaging one of said jaws, floor bearings for said standards, eccentrically mounted rollers for said standards and being trunnioned in said bearings, means to rotate said rollers to allow for the horizontal travel of the jaws, a counter-balancing means for one of said jaws, and means to support the counter-balancing means from the standard adjacent the pivot for said jaws.
2. In an auxiliary centering chuck, a pair of arcuate shaped jaws pivotally connected together at one end and being provided with a plurality of dovetailed slots radially disposed on both sides thereof, U-shaped frames slidably mounted in said slots, a pipe fitting gripping tooth for each frame and being removably position in the inner end thereof, screw means carried by said jaws for ad justing said frames radially thereof, a pair of standards including pivoted parts and being pivotally secured to the lower jaw, eccentric bearings for the lower ends of the standards, means to rotate said bearings, a yoke eccentrically pivoted to the lower jaw adjacent its free end, a yoke carried by the yoke first mentioned, a lip extending from the other jaw and being adapted to receive the last mentioned yoke for securing the jaws in operative position, arms secured to one of said standards, a sheave wheel journaled between the outer ends of said arms, a cable trained about the sheave wheel and attached to the upper jaw, and a weight socured to said cable and operating as a counter-balance for the upper jaw.
3. A device of the character described com prising a pair of arcuate shape jaws pivotally connected together at one end, a pair of standards pivotally supporting said j aws, eccentrically mounted roller bearings for said standards, a bearing for each roller bearing and being rigidly secured to a floor, springs obliquely extending from the sides of each of said standards for normally supporting the standards in a vertical position, frames slidably mounted on the jaws and being adjustable radially with respect there to, a tooth secured to and inwardly extending from each frame, screws carried by said closed position, a counter-balancing means ews for ad ustlng the frames, an eccentuc supported by one of sad standards and yokepivotally connected toone ja-n aseeond being adapted to move the last mentioned 10' yoke trunnioned on the first mentioned yoke Jaw to open position and retain the same and belng actuated thereby, an outwardly accordlngly. extending hp on the other jaw for recelvlng the last mentioned yoke to hold the jaws in JOSEPH M.
