ATTACHMENT FOR PIPE-DIES.
Application filed September 27, 1915.
To all whom it may concern:
Be it known that I, Amos F. Bacon, a citizen of the United States of America, residing at Fremont, in the county of Newago and State of Michigan, l1 ve invented certain new and useful Improvements in Attachments for Pipe-Dies; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to an attachment for manually operated pipe dies, whereby the same may be readily operated by any convenient mechanical power, and it consists essentially of a sprocket wheel adapted to be at tached in place of the usual manually operated lever or levers; a stationary sprocket pinion rotated by any convenient mechanical power and a sprocket chain connecting the wheel and pinion and provided with slack or excess length enough to permit a planetary movement of the wheel about the axis of the dies and also to permit ready detachment of the chain from the said wheel, whenever it is desired to manually rotate the wheel to back off the dies after the thread has been cut, as hereinafter more fully described and particularly pointed out in the claims, reference being had to the accompanying drawings in which Figure l is a plan View of geared pipe dies as usually made with my device applied thereto; Fig. 2 a front elevation of the same; Fig. 3 a plan view of the ordinary nongeared manually operated dies shown on a larger scale than Figs. 1 and 2 and having a modification of my device attached thereto, and Fig. 4 a front elevation of the same.
Like numbers refer to like parts throughout the several views of the drawings.
1 represents the dies proper for cutting the thread; 2 the housing or head carrying the cutting dies; 3 a disk rotative on a collar 7 held fixed by set screws 8 on the pipe 9 which pipe is held in any convenient pipe vise (not shown).
l is a sleeve having a thread of the same pitch as is out by the dies; 5 are studs fixed in the disk 3; and slidable in the head 2; 6 is a stationary spur gear on the collar 7.
10 is a spur pinion fixed on the end of a shaft 17 journaled in a bearing 11 fixed in the disk 3 extending through a boss 12 on the head 2 and slidable on the said bearing. This pinion has a planetary movement about Specification of Letters Patent.
Patented Jan. 18, 1916.
Serial No. 52,867.
the fixed gear 6 and the head 2 and disk 3 together with parts attached is rotated about the axis of the dies by means of a ratchet lever (not shown) detachably applied to the squared end of the sh aft 17.
So far the described device is a well known manually operated geared pipe die adapted to be manually operated.
My invention consists of the following: A sprocket wheel 13 is applied to the end of the shaft 17 in place of the usual manually operated ratchet lever and partakes of the planetary movement of this shaft about the axis of the dies. Any convenient powerdriven stationary driving sprocket pinion 15 is provided and is connected to the wheel 13 by a sprocket chain 1%, of such length that there will be slack enough of the same to permit the planetary movement of the wheel 13, as illustrated in Fig. 2. To insure that the chain will not slip on the pinion the lower part of the chain passes over an idler pulley 16 to carry the chain into contact with the under side of said pinion. llhe weight of the slack part of the chain is sulficient to maintain ample engagement with the pinion 15. However, for all ordinary work the said idler is not necessary.
In operation when cutting the thread the wheel 13 is rotated by the chain and as the said wheel and parts driven thereby move around the axis of the dies, the slack of the chain is alternately taken up and paid out. When the thread is completed the power is turned off and the machine stopped with slack enough in the chain 14 so that it can be readily removed from the wheel 13, whereupon said wheel can be manually rotated in the opposite direction to back off the dies.
Figs. 3 and 4: illustrate a modification of my device applied to ordinary pipe dies devoid of the planetary gearing and usually operated by levers inserted in sockets 1E2 on the head 2. My modified device consists of a sprocket wheel in the form of a ring 13, secured to these sockets 12 concentric with the axis of the dies by clips 18, and the chain it applied thereto with slack enough so that the chain can be readily removed from the wheel for manually backing off the dies from the pipe after the thread is cut the same as in the case of the geared dies.
What I claim is:
1. In combination with pipe dies, a sprocket wheel attached to the dies to rotate the same, a driving sprocket pinion, and a chaln connecting the pinion and Wheel and arranged with suflicient slack to permit ready detachment of the chain from the Wheel to permit the Wheel to be manually rotated.
2. In combination with pipe dies having planetary gearing, a sprocket Wheel connected to the dies and having planetary movement, a stationary driving sprocket pinion, and a chain connecting the gear and pinion and having length enough to provide slack to permit the planetary movement of the gear and ready removal of the chain from the gear to permit manual rotation of the gear.
3. In combination With pipe dies having a fixed gear concentric With the axis of the dies and a planetary pinion to rotate the dies, a sprocket Wheel connected to the pinion and also having a planetary movement about the axis of the dies, a stationary sprocket pinion, a chain connecting the sprocket gear and the sprocket pinion and provided With slack enough to permit said planetary movement of the sprocket gear and an idler pulley to carry the slack side of the chain in contact With the under side of the sprocket pinion.
In testimony whereof I aflix my signature.
