TUBE-CUTTING MACHINE.
SPECIFICATION forming part of Letters Patent No. 771,752, dated October 4, 1904. Application filed Juno 8, 1903. Borbllo. 180.547. (No model.)
To all whom it may concern:
Be it known that I, FRANK R. STAFFORD, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Tube-Cutting Machines, of which the fol owing is a specification, reference being had therein to the accompanying drawings.
Like characters indicate like parts.
The purpose of this invention is to provide a machine by which a tube can be cut into ferrules or rings without waste.
Figure 1 is a central vertical section of my improved tube-cutting ma hine as seen on line as w of Fig. 2,. the tube which is to be cut, the vertical locking-pin, and the guide-rod being ,shown in elevation as seen at the beginning of an operation. Fig. 2 is a view of said machine as seen on line y y of Fig. 1, the tube which is to be cut, the horizontal locking-pin, the compound telescoping tubes, and cylindrical rod or plug being shown in top plan. of said machine as seen on line a: w of Fig. 2 at the end of an operation. Fig. 4 is a view, partly in top plan and partly in cross-section, as seen on line-z 2 of F g. 3. Fig. 5 is a perspective view of said machine. Fig. 6 is an elevation of the feed-rod and its support. Fig. 7 shows in side elevation the rod or plug, the several tubes, and adjusting-screw. Fig. 8 is a central vertical section of the feed-rod, the plug, the tube mounted in position to be cut, and the cutting-collars and their supports. Fig.9 is a perspective view of the ring which is cut by' the operation of said machlne.
My invention relates to machines for cutting rings, ferrules, and similar articles; and it consists of the novel constructionand combinationof the several parts,as hereinafter de scribed,and specifically set forth in the claims.
In the drawings, 1 represents the base of the machine, which has a flange 2, by which it is held to the bench or other support by clamps 3 or by other suitable means. Said base has acircular bore through it from front to rear, in which is inserted the guiderod 4..
Fig. 3 is a central'vcrtical section Integral with the base 1 is' the standard 5, which is provided with a vertical guideway 6, whose ends are inwardly beveled convergingly to the rear. in this standard is mounted a fixed cutting-collar 7 in a circular aperture made therefor. This aperture has a concentric enlargement forming an internal shoulder, and the fixed collar 7 has a flange on its outer end which is received in said enlargement of the aperture and abuts said internal shoulders, as seen in Figs. 1, 2, 3. and 8. An opening 8 extends through the lower portion of the stands rd 5 and allows the ejection of the ring Qafter it has been out, which is the product of said machine. Upon the base 1 are fastened the two upright sides 10. These upright sides have flanges or feet 11 and are fastened in position by screws 12, which pass through the flanges 11 into the base 1, as seen in Figs. 1 and 4. Each upright side 10 has a slot 13 therein, the upper part of which slot is vertical and the lower part is angularly directed downward and toward the front, as illustrated in Figs. 1, 3, and 5.
therefor in the head 16 of a press and is fastened in position by a pivot 17 or otherwise. The plunger 14 is dovetailed in cross-section, as seen in Figs. 2, 4, and '5, and has a conical transverse bore in which is fastened a cutting-collar 18, asseen in Figs. '1, 2, 3, and 4. The plunger 14 has an integral backward extension 19, which is provided with a vertical bore for the reception of a vertical lockingpin 20 and also with a horizontal bore in which a tube 21 and its contained parts are mounted. ".he tube 21 has a longitudinal bore 22, two
A plunger. 14 has a spindle 15, which enters a socket made diametrically opposite longitudinal slots 23, I
and two circular holes 24 near its end and directed diametrically and at right angles to said slots 23, as indicated most plainly in Fig. 7. One end of said tube is concentrically reduced, as seen at 25, and is provided with. a circumferential groove 26. A cylindrical bar 27 is mounted movably in the bore 22 of the tube 21, and its end 28 is screw-threaded. Said bar has an elongated diametrical slot 29 through it. For about one-half its length said bar 27 has a tubular socket 30, and
' through said tubular part there are two diametrically opposite longitudinal slots 31 and two transverse circular holes 32, directed at right angles with said slots 31. A tube 33 is movably mounted in the tubular socket 30 of the cylindrical bar 27 and is provided with two diametrically opposite longitudinal slots 34 and two diametrically opposite circular holes 34. A cylindrical rod 35 or plug is movably mounted in the tube 33 and has a transverse diametrical circular hole 36 through it. A cap 37 has a knurled head 38, a tubular socket 39, a screw-threaded bore 40, and a chamber 41, all concentric'with each other. The extension 19 of the plunger has the diametrically opposite slots seen at 42. These parts (shown separated in Fig. 7) are assentbicd as follows, as shown in Figs. 1, 2, 3, and 4: The locking-pin passes through the slots 23 of the tube 21 and through the slots 31 of the tubular portion 30 of the bar 27 and through the slots 34 of the tube 33 and through the hole 360i the rod 35. The cylindrical bar 27 passes through the tube 21, and its screw-threaded end 28 engages with the screwthreaded bore 40 of the cap 37 and projects into the chamber 41 of said cap. The reduced end of the tube 21 enters loosely the socket 39 of the cap 37, and a screw 43 through one side of the cap has its inner end projecting into the circumferential groove 26 of the end of the tube 21.
A horizontal locking-pin 44 passes through the holes 32 of the tubular portion of the cylindrical bar 27 and through the holes 34" ofthe tube 33. A bolt45 has screw-threaded ends and passes through the slots 13 of the sides 10 of the base 1 and through the slots 42 of the rear extension 19 of the plunger 14 and through the holes 24 of the tube 21 and through the slots 29 of the cylindrical bar 27. On the ends of the bolt 45 are the nuts 46 and the washers 47, the latter being of a width exceeding the width ofthe slot 13.
In the guideway 6 onthe two beveled sides thereof there are guide-plates 48, extending down longitudinally therein and held in position by the adj listing-screws 49. The plunger 14 slides in contact with these plates, as seen in Figs. 2, 4, and 5. 1
A feed-rod 50 has a head 51, through which is a transverse hole. A-rod-holder 52 has a tubular socket for the reception of the head 51 of the feed-rod 50, and extending axially therefrom is a hinge member 53. A plug 54, having a handle, passes through holes made in the holder 52 therefor and through the transverse hole in the feed-rod, as seen in Figs. 5 and 6. 1n the socket in the holder 52 is a spiral spring 55. On the rod 50 is slidably mounted the tube 56, which is to be cut into rings by the operation of the machine.
A standard 57 is movably mounted on the bench or other proper support and is provided with two upright parallel cars 58, constituting a hinge member, between which the hinge member 53 is loosely inserted. The hinge members 53 58 58 are pivotally connected by a pintle 59.
A keeper 66 is pivotally mounted at 61 to the standard 5 of the machine and has a slot 62 at its free end which is adapted to receive a stud ors'crew 63, extending from the standard 5, as seen in Figs. 1, 3, and 5. The keeper has a central round aperture 64, through which the feed-rod 50 extends with the tube 56.
The standard 57 has a horizontal bore near the bottom, in which the guide-rod 4 is loosely mounted, and a set-screw 65, passing through a hole tapped therefor inthe standard 57, holds said rod 4 in its, adjusted position.
Having thus described the parts of said machine. I will now explain its operation.
The keeper 60 serves to confine the cutter or collar 7 in position, as can be understood by examining Figs. 1, 3, and 5. hen it is desired to remove said cutter or collar 7, as when a tube 56 of a different diameter is used, the keeper 6() is lifted from the stud 62 and swung up and over out of the way, thus giving access to the cutter or collar 7 for the purpose of such removal. When another cutter or collar 7 is put in operative position, the keeper 60 is swung down and over the outer end thereof and holds it from displacement. The cutter or collar 18 can be removed from the plunger 14 when said plunger is in the po- -.'sition shown in Fig. 3.
The width of the ring 9 tobe out can never cut into rings or ferrules of the desired length and absolutely without any wast For this reason the machine is well ada pted to make seamless finger-rings from solid-gold tubes or from gold-plated tubes or tubes or pipes of any metal.
It is obvious that instead of having one cutting-collar mounted in a fixed support and the other cutting-collar mounted in a verticallymovable support either or both of said supports may be rotatable or otherwise movable.
