MACHINE FOFi HELICALLY CORRUGATING PIPE.
Specification of Letters Patent.
Patented Oct. 31, 1905.
Application filed June 23, 1905. Serial No. 266,577.
To all whom, it may concern,.-
Beit known that we, JOHN DOVE IsAAcs, residing at Oakland, and J AMES BUCKNER SPEED, residing at Berkeley, Alameda county, State of California, citizens of the United States, have invented certain new and useful Improvements in Machines for Helically Corrugating Pipe; and we hereby declare the following to be a full, clear, and exact description of the same.
Our invention relates to apparatus to be used in connection with that art or method of piping fiuid which consists in advancing the Huid, together 'with a second fluid of greater specific gravity, -through a pipe having a helically-directed internal obstruction whereby a helical motion is given to the fluid content about its axis which is sufficient to envelop the lighter iuid with the heavier fluid, and thereby reduce friction against the pipe-walls. This method is fully disclosed in Letters Patent of the United States N o. 759,37 4, granted to us May 10, 1904, and to which reference is hereby made. A form ofhelically-corrugated pipe which we deem best adapted for use in carrying out this method we disclose in a contemporaneous application, and our present invention relates to a machine for making said pipe.
Our invention consists in the novel machine and in the construction, arrangement, and combinations of its parts, which we shall hereinafter fully describe by reference to the accompanying drawings, in which- Figure lis afront elevation of our machine,
showing the pipeP in place to be corrugated.`
Fig. 2 is an elevation with the outer chuck removed and the wedge-carrier broken. Fig. 3 is a side elevation of the machine, one of the frame-timbers A being removed. Fig. 4 is a rear elevation showing the power-lever M mounted on the frame-timbers. Fig. 5 is a sectional view of the two chucks and intervening wedge-carrier to show the fitting thereto of one of the separation-limiting shafts F. Fig. 6 is a similar view showing the fitting of one of the chuck-operating shafts Cr. Fig. 7 is a detail side view of the pressure-roller and wedge engagement. Fig. 8 is anend View of the same. Fig. 9 is adiagramrnatic'sectional view to show the relative arrangement of the pressure-rollers of the two chucks with respect to the pipe P, which they helically corrugate. Fig. 10 is a sectional detail to show the approach-limiting stops J and K as tted to their respective parts.
A represents two lheavy timbers between which at one end is .securely bolted the inner chuck B. In this chuck, as shown in Fig. 2, are mounted the corrugating-rollers C, said rollers being borne in the forked shanks D, which are slidably mounted radially in the chuck, their outer ends extending to wedgeways Z2, made through the chuck. There are four of these rollers, though their number is not essential, as there may be a greater or less number, according to the number of corrugations which it may be desired the pipe shall have. Each roller is set at an angle to the axis of the chuck and is consequently at an angle to the axis of the pipe P to be corrugated and which is passed through the chuck, so that the result of the pressure of the rollerupon the pipe will be to make a helical indentation on the outside of the pipe, with acorresponding elevation on the inside. (See Figs. l and 9.) To adjustthe rollers to the proper angle, they are governed by the set-screws c, tapped into the chuck.
B' is the outer chuck. Init are mounted four rollers C', as shown in Fig. 1, said rollers being mounted in the forked Shanks D', which are slidably mounted radially in the chuck and extend to wedgeways made in said chuck, all similar to the construction of the rollers of theinner chuck. These rollers of the outer chuck are also similarly adjustably set at an angle to the axis of the chuck and line of travel of the pipe; but their position yrelatively to the position of the rollers of the forward chuck is alternating or staggering, whereby the rollers of the outer chuck lie in the helical lines of the rollers of the inner chuck, as seen in Fig. 9.
The outer chuck is carried upon four shafts, which extend between it and the inner chuck. Two of these shafts (represented by F) are the separation-limiting shafts, and two (represented by Cr) are the operating-shafts, as will be presently described. Between the two IOO Fig. 3, there being eight in all, four on each side, said wedges being connected with the carrier by means of their Shanks c', iixed therein by suitable means. These wedges are adapted to operate in the wedgeways 7) and of the two chucks, and they act against the outer ends of the forked Shanks D and D', which carry the pressure-rollers C and C. The connection between the wedges and the outer ends of the forked shanks is a positive one, as is indicated by the dovetail at rl in Figs. 7 and 8, so that as the wedges withdraw they positively withdraw the pressure-rollers.
lt will now be seen that if the wedge-carrier be forced toward the inner chuck and at the same time the outer chuck be forced toward the wedge-carrier the wedges of the latter will cause the pressure-rollers of both chucks to be forced in upon the pipe. The means for effecting this operation are as follows: J represents stops in the form of screws which are tapped in the outer chuck and have their inner ends adapted to bear against the wedge-carrier. (See Figs. 3 and 10.) K represents stops in the form of screws which pass freely through the outer chuck and are tapped in the wedge-carrier and have their inner ends adapted to bear againt the inner chuck, as seen in Fig. 10. When, therefore, the outer chuck is drawn toward the inner chuck, the stops J coming in contact with the wedgecarrier will force the latter to move with it toward the inner chuck until the stops K bear against said inner chuck, whereupon the wedge-carrier will be arrested and all its wedges will act to force the pressure-rollers of both chucks upon the pipe. These stops J and K also define the approach of the several parts. To accomplish this approach of parts of the machine, the two operating-shafts Gr are connected at their outer ends rigidly with the outer chuck D by means of the nuts g. The said shafts pass freely through the wedge-carrier and through the inner chuck, as seen in Fig. 6, and are connected at their inner ends by means of links L, Fig. 3, with the forked end m of the lever M, mounted on a shaft N at rear ends of the frame-timbers A, Fig. 4f. In order to properly separate the parts of the machine again and overcome the tendency of the wedges to stick, the guideshafts F are shouldered at f and headed tightly in the outer chuck and are shouldered at f to bear against the inner surface of the wedgecarrier, as seen in Fig. 5, and said shafts pass slidably through the carrier and the inner chuckand receive nuts f2. When the parts are being separated by a pushing force on the shafts G, the outer chuck by being firmly connected to the shafts F will carry said shafts outwardly, which will in due time pick up and move outwardly the wedge-carrierH by their shoulders f. In order to define the separation of the wedge-carrier from the inner chuck, a suitably-headed link O is caused to engage the two, as seen in Figs. 3 and 9.
The operation of the machine is as follows: When the two chucks and the intervening wedge-carrier are separated to their greatest extent, the pipe P is passed through the machine from the outer chuck inwardly. By means of the lever M the parts of the machine are brought together sufficiently to cause the rollers to bear upon the pipe in proper position. A `hauling-line being secured to the inner end of the pipe and the lever M being moved to force the chucks together to cause the wedges to force the rollers upon the pipe with suiiicient pressure to make the necessary corrugations, the pipe is drawn forcibly through the chucks, and in its passage it turns on its axis by reason of the angling pressure of the rollers, so that the helicalfcorrugation is made in the pipe. To relieve the pipe, the operating-lever is moved, thereby forcing the chucks apart and causing each part of the machine to separate its proper distance and causing the wedges to withdraw the rollers.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
l. In a machine for helically corrugating' pipe, the combination of a chuck, a radiallymovable roller carried by the chuck and set at an oblique angle to the axis of the chuck, a wedge-carrier opposite to and parallel with the face of the chuck, a wedge mounted on said carrier and projecting toward the chuck, said wedge being adapted to force the roller on the pipe, and means for effecting the approach of the chuck and carrier to cause the wedge to actuate the roller.
