TUBE OR ROLL FORMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 749,114, dated January 5, 1904.

Application filed January 16, 1903. Serial No. 139.307. (No model-l To all whmn it may concern:

Beit known thatwe,CHARLES SURMANN and ROBERT D. DOUGLAS, citizens of the United States, and residents of Fall River, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Tube and Roll Forming Machines, of which the followingisafull,clear,.and exact description.

This invention has relation to certain novel and useful improvements in a machine for forming tubes, rolls, or the like, and has particular application to a mechanism of this character adapted to wind tubes, cloth, or the like.

Primarily we have in view as an object the production of a tubing-machine the sections whereof forming the mandrel will be capable of being readily moved toward or from each other, thus enabling the tube or roll to-a't'alt times have a positive hearing or support inside the same, yet when it is desired to remove the tube or roll from the'mandrel the cirjunction. with the sections, to form a rela-.

tively enlarged mandrel having a smooth circumferential surface.

We also contemplate providing an improved construction for moving the mandrelexpanding means into and out of position between the free edges of the sections, whereby we are enabled to avoid the use of cumbersome and complicated toggle-joints, sliding rods, and the like.

A further object of the invention is to provide means for drawing the free edges of thesections into contact, thereby reducing the circumference of the mandrel when the expanding means have been moved from between the edges.

With these and other objects of a similar nature in view our invention consists in the construction, combination, and arrangement of parts, as described in this specification,

delineated in the accompanying drawings,

Figure 1 is a central longitudinal sectional view of our improved mandrel having a tube thereon, the frame and other interior portions being shown in full lines. Fig. 2 is a transverse vertical sectional view of a mechanism embodying our improvements, the sections of the mandrel being shown in their enlarged or expanded position. Fig. 3 is a similar view, but showing the mandrel in its contracted position. Fig. 4 is a view of one of the supports or standards forming a part of the'interior frame of the mandrel. Fig. 5 is a detail perspective view showing the key employed in operating the mandrel-expanding means, and Fig. 6 is a detail perspective view of a fragment of the key-bar.

In the accompanying drawings, wherein there is delineated a mechanism embodying our improvements, 1 designates a shaft or axle which is rotatably mounted in any preferred manner and which may be driven or actuated by any suitablyapplied power. Upon this shaft we have mounted standards or supports which form what for the sake of convenience we term the main frame. As will be seen especially'by reference to Figs. 1 and 4, these supports comprise collar-like portions 2 2, each having an enlarged member or standard 3 formed at one end thereof, a bore extending entirely through the collars, and the enlarged member for the passage of the shaft 1. The members of the frame may be secured rigidly to the shaft in any approved manner, such as by bolts or pins, which pass through the collar portions 2 2 and through the shaft, such pins being shown in dotted lines in Fig. 1. Each of the members or portions 3 3 is provided with an extension or ear 4, which is apertured or bored, as at 5, (see Fig. 4,) to permit the passage of the rod 6, the construction being such that the apertured portions of these supports or standards form bearings for said rod. The rod 6 is provided with a collar or washer 7 near each end,

which collars bear against the outer surfaces of the extension 4:, and bearing against these washers or collars 7 7 are apertured lugs 8,

formed on the interior edge surfaces of the approximately semicylindrical mandrel-sections 9. As will be observed particularly by reference to Fig. 2, the under surfaces of the free longitudinal edges of the sections are beveled or inclined, as at 10, for a purpose to be hereinafter described, the immediate contiguous portions of the sections being approximately fiat or parallel to each other, as at 11. It is to be noted that when the sections are closed so that the edges 11 are in a position to contact the mandrel has its smallest possible diameter in cross section. For the purpose of expanding the mandrel we have provided the following means: Formed in the end of each of the supports 3 3, opposite the ear 4, is an orifice 12, each orifice beving adapted to permit the passage therethrough of an end portion of a bar 13, approximately similar in construction and proportions to the rod 6. Each end of said bar is formed with a flattened or squared portion 14 to provide a grasping or gripping surface for a wrench, and mounted near each of the flattened portions is a cam -key comprising a collar portion 15, adapted to be secured through the medium of a suitable screw 16 to the bar 13, and formed integral with this collar portion is an extension or cam 17. Each of the supports 3 3 is provided with a socket or radially-extending bore 18, as is shown by dotted lines in Fig. l, and within each socket is adapted to be seated a stud 19, the stud being connected with and supporting a key-bar 20. This key-bar forms an important feature of the invention and hasits uppersu rface slightly convexed, as at 2l,and inclined downwardly and outwardly away from the curved surface are the sides or shoulders 22, a short vertical abutting wall 23 being formed between the convexed top and the upper edge of the shoulder, such wall being adapted when the bar is in its mandrel-expanding position to bear against the vertical edges 11 of the sections of the mandrel 9. Secured a short distance from each end of the bar and extending downwardly from the under surface thereof is a plate 24, provided with a slotted or recessed portion 25, adapted to form a lip or extension 26, the recess being in alinement with the curved extension or cam portion 17 of the key, the construction being such that when the shaft or bar 13 is turned for the purpose of moving the bar radially outward the cams 17 of the keys 15 will strike against the upper walls 27 of the plates 24 and move the bar; but when it is desired to draw the bar radially inward the key is turned in the opposite direction and the cam portion abutting against the lower shoulder or lip 26 forces the key inward. For the purpose of drawing the semicylindrical sections intoa position of contact any suitable means may be employed, such as the tension-springs 28, connected at one end to the shaft 1 through the medium of books 29, and at the outer ends these springs are secured to the semicylindrical sections of the mandrel 9 by similar books 30. It is of course to be understood that any suitable number of these springs may be employed and any suitable number of keys and plates, this depending upon the size of the machine. The outward movement of the cam-key away from the locking-bar is limited by stops or studs 31, formed on the frame-standards 3.

From the above description, taken in connection with the drawings, the construction and operation of the machine will be readily apparent. The key being forced radially outward spreads the sections or jaws of the mandrel into the position shown in Fig. 2 and the strip of paper or the material A to be rolled is wound around the mandrel to'the desired thickness. When it is desired to remove the tube from the mandrel, a wrench or other suitable means is applied to the fiattened or squared end of the rod 13 and such rod is turned to bring the cam portion of the key into contact with the lower shoulder and the key-bar is turned radially inward toward the main shaft. The tension-springs as soon as the key-bar leaves the space between the semicylindrical mandrel-sections draw the latter together into abutment or contact at their longitudinal edges, and the circumference of the mandrel being thereby greatly reduced the tube or roll may he slipped from the same.

Many advantages incident to a device of this character will be immediately apparent. Itis to be noted that We avoid the use of togglerods, levers, and the like for holding the mandrel in its expanded or reduced position and at the same time have provided a structure which is economic, extremely durable, and capable of acting with great positiveuess. Heretofore in devices of this general character one disadvantage has been incident to the same-namely, that when an attempt was made to remove a tube or roll from the mandrel only a small section of the semicylindrical wail could be moved inward, the main portion of the circumference being fixed or rigid, and it was necessary to strike the tube a sharp blow upon the body or circumference thereof to loosen the same upon the mandrel, which striking or tapping oftentimes resulted in the abrasion or damaging of the material and the flattening or distortion of the tube. In the present instance the diameter of the mandrel-body is so reduced that the tube maybe removed with facility and without any such striking or tapping as has been mentioned. It is to be observed that in addition to forming paper tubes or the like upon our mandrel it is also exceedingly convenient for the purpose of winding cloth or any material, in fact, this being accomplished by placing a paper tube upon the mandrel and expanding the latter, so'that it frictionally holds the tube, and then winding the cloth or other products upon the said tube. When the desired quantity of goods has been rolled or wound upon the tubes, the size of the mandrel is reduced, as heretofore explained, and the tube with the goods thereon is removed.

While we have shown and herein described one particular embodiment of our invention, we wish it to be understood that we do not limit ourselves to the precise details of The illustration herein, as there may be modifications and variations in some respects without departing from the spirit of the invention or sacrificing any of the advantages thereof.
