JULIUS H. SCI-ILAFLY, OF CANTON, OHIO, ASSIGNOR TO THE BERGER MANU- FACTURING COMPANY, OF CANTON, OHIO.
MACHINE FOR TAPERING THE ENDS OF CORRUGATED P'IPES.
SPECIFICATION forming part of Letters Patent No. 707,648, dated August 26, 1902.
Application filed March '31, 1902. Serial No. 100.743. (No model.)
To all 1072 0112 it may concern: 7
Be it known that I, JULIUS H. SCHLAFLY, a citizen of the United States, residingat Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Machines for Tapering the Ends of Corrugated Pipes; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, reference be- IO ing had to the annexed drawings, making a part of this specification, and to the figures of reference marked thereon, in which- Figure 1 is a front end view. Fig. 2is a Vertical section through the center of Fig. 1 and at right angles thereto. Fig. 3 is a vertical section through line as :0, Fig. 1. Fig. 4 is a View showing the arrangement of the power-shaft with reference to the drivingpinion and the different eccentric and cam driving gear-wheels. Fig. 5 is an enlarged view of the seaming-die and its cam. Fig. 6 is a detached view of one of the taper-forming dies. Fig. 7 is a detached view of the mandrel.
The present invention has relation to ma chines for tapering the 'ends of corrugated pipe; and it consists in the different parts and combination of parts hereinafter described, and particularly pointed out in the claims.
Similar numerals of reference indicate corresponding parts in all the figu res of the drawlngs. v
The drawings show the machine adapted to taper the ends of corrugated pipe; but it will 5 be understood that plain round pipe may be tapered Without departing from the nature of my invention, it of course being understood that all that is necessary to do, to change from corrugated pipe to round pipe or any 40 other form of pipe, isto give to the mandrel and the dies the configuration corresponding with the pipe designed to be operated upon.
In the accompanying drawings, 1 represents a base or support to which is attached in any convenient and well-known manner the shaftbearing frames 2 and 3, which shaft-bearing frames may be formed integral with the base or support 1, or they may be made separate and connected thereto in any convenient and well-known manner. To the frames 2 and 3 is properly journaled the power-shaft 4, and
for the purpose of providing proper bearings for the shaft the frames 2 and 3 should be provided with the inner projecting flanges 5 and 6, which flanges are simply for the purpose of increasing the amount of metal atthe bearing-points of the power-shaft. Upon the power-shaft 4 is located the pinion 7, which pinion is securely fixed to the power-shaft in any convenient and wellknown manner. The pinion 7 meshes with the cog-wheel 8, which cog-wheel imparts rotary motion to the cog-wheels 9 and 10, and the cog-wheel 10 imparts rotary motion to the cog-wheel 11; but it will be understood that the teeth of the cog-wheels 9 and 11 should not mesh, but should be spaced from each other, as illustrated in Fig. 4. The various cog-wheels 8, 9, 10, and 11 are mounted upon the shafts 12, 13, la, and 15, which shafts are properlyjour- 7o naled in suitable bearings 16 and 17. The bearings 17 are preferably formed separate from the frame 2 and properly connected to said frame in any convenient and well-known manner, or they may be made integral with the frame 2, if desired, this being a question for the mechanic to determine.
To the frame 2 or its equivalentis connected the mandrel 18, which mandrel is provided with the tapered end 19, and for the purpose of easily placing a pipe upon the mandrel the mandrel proper istapered so that its end will be smaller in diameterthan the diameter of the pipe designed to be operated upon, this arrangement being necessary or at least 0011- venient, as the pipe can be easily placed in position. The mandrel 12 is held in proper position by means of the lug-bolt 20 or its equivalent, which lug-bolt is connected to the frame 2. 0
Upon the different shafts 12, 14, and 15 are located the eccentrics 21, and upon the shaft 13 is located the cam 22, said eccentrics and cam being located substantially as shown in Fig. 1 and are for the purpose of forcing the dies 23 and 24: toward the mandrel 18, which come in contact with the end of the-pipe designed to be operated upon. The dies 24are all formed substantially alike and the workingfaces thereof formed to correspond with the tapered portion 19 of the mandrel 18. The die 23 is a seaming-die or, in other words,
clamps the seam of the pipe, and for the purpose of holding this die down upon the seam at the proper time with reference to the corrugating-dies said die is operated by means of the cam 22.
For the purpose of holding the dies 23 and '24 in proper relative position they are each provided with the flanges 25, which flanges are provided with the beveled edges 26, and over which beveled edges .are located the retaining-plates 27, which retaining-plates are secured by suitable bolts 28 to the frame 2, said plates being provided with beveled inner edges corresponding with the beveled edges upon the flanges. of the various dies. The various die-retaining plates 27 are so arranged with reference to each other that they will form guides for the reciprocating movement of the various dies, and for the purpose of automatically moving the dies 23 and 2 away from the mandrel after they have performed their function upon the pipe the dies are provided with the outward-extending bolts 29, which bolts pass through suitable apertures 30, formed in the flanges 31, which flanges are formed integral with the frame or plate 2 and the outer ends of the bolts 30, provided with the heads 32, and between the heads 32 and the flanges 31 are located the springs 33. As the various eccentrics and the cam force the dies inward the springs 33 will be compressed, owing to the fact that the bolts 29 move with the various dies and by the reaction of the springs will carry the dies away from the mandrel after they have been released or the pressure of the various eccentrics and cam removed from the outer edges of the dies.
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a machine of the class described, a base or support, frames carried thereby, a powershaft provided with a pinion, co wheels driven from the pinion upon the powershaft, a series of shafts located around the power-shaft, dies capable of reciprocating movement, and means for forcing the dies inward or toward each other, and a mandrel provid ed with a tapered portion, substantially as and for the purpose specified.
2. In a machine of the class described, a base or support, frames carried thereby, a power-shaft provided .With a pinion, cog- Wheels driven from the pinion upon the powershaft, a series of shafts located around the power-shaft, dies capable of reciprocating movement, and means for imparting a reciprocating movement to the dies and a mandrel, substantially as and for the purpose specified. V
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
