SPECIFICATION forming part of Letters Patent No. 291,500, dated January S, 1584:.V
Application tiled May 2l, 1853. (No model.)
y citizen of the United States, residing at Mason,
inthe county of Effingham and State oflllinois, have invented certain new and useful Improvements in Wire-Coiling Machines, of which the following is a specification.
`My invention relates to that class of wirecoiling machines in which the wire is pushed by suitable mechanismthrough a spiral groove, and thereby formed into a continuous spiral coil of any desired length.
The objects of my improvements are, first, to prevent the clogging of the wire in the coiling device; and, second, to provide improved means `for accurately adjusting the relative position of the wire-guide and thecoiling device. These objects I accomplish by means of the mechanism hereinafter described, and illustrated inthe accompanying drawings, in whichfu Figure I represents a perspective view oi' my machine. Fig. Zlis a plan of the wire-guide `and the ceiling device and adjustable supports therefor. Fig. 3 is an enlarged perspective view of the grooved cylinder forming part of the ceiling device.
A casting, a, forms the frame of the machine.
b c are friction-wheels, having on their pe ripheries, or a portion thereof7 intermeshing cog-teeth. Said wheels are mounted on shafts d and e, having bearings in the frame a, the bearings of e being vertically movable in frame a, and held in position by a set-screw, j", and spring g at each end. Theperipheries of wheels b and c are each provided with a groove, 7L, adapted to receive the wire passing between them. A hand-wheel, i, secured to shaft d, serves to drive the wheels b and c.
'Ihe machine thus far is similar in all re; spects to that shown in Letters Patent No. 278,483, granted to me March (i, 1883. In the coiling device there shown the spiral groove which forms the coil is on the exterior of `a mandrel, and the wire is forced to follow said groove by a semi-cylindrical cap, smooth on its interior, and secured to the exterior of the before-mentioned mandrel.` In all machines of this class of which I have any knowledge heretofore thc spiral groove has been formed in the exterior of a mandrel, and various means have been used to cause the wire to follow the groove, 1
It has been found in practice that the normal tendency of the wire to move in a straight line against the confining-shell or semi-cylin der causes the interior of the confining-shell to wear in such a manner that the end of the wire, when starting in, is liable, particularly if the parts are Vnot closely iitted, to leave the groove and be forced into the joint between the mandrel and its shell, and thereby clog and stop the machine and spoil the coil. In my present machine I remedy this difficulty by making the exterior of the coil-forming mandrel j smooth, without grooves. Upon said mandrel I slip a hollow cylinder, k, nicely fitted thereto, and which I secure thereon by a pin or set-screw, 7u. The interior of cylinder It has one or more spiral grooves, w, formed therein, as shown in Fig. 3. Only one of said grooves is used at a time; but several are provided, so that when one-becomes worn another may be used, as hereinafter explained. `One end of cylinder k is notchedor filed away at the commencement of the grooves, as. at Z, so as to present a surface nearly at a right angle to the spiral li ne of the groove, for the purpose of properly introducing the wire. The normal tendency of the wire to move in a straight line now causes the wire to press closely into and against the bottom of the groove, and there is consequently no tendency to get into the joint between the cylinder and mandrel. In my formerly-patented machine the wiregui de and the eoiling device were separately mounted in opposite sides of the frame, and it has been found difficult to properly adjust and n1aintain their relative positions. In my present machine a bar, m, is secured by a set-screw in a socket, In., in frame u. The wire-guide o is passed through m, near the free end thereof, and is secured by a set-screw, p. The bar m and wire-guide o are each adapted to be adjusted by being turned or moved longitudinally in their sockets.
The wire-coiling device, instead of being secured in a socket in the frame, is secured in aA casting, r, which is adapted to slide and turn on bar m, and which is secured in position on said bar by a set-screw, s. lIhe ceiling device is secured in r at such a'n angle as to bring the IOO entrance to one of the grooves in cylinder k in exact line with the Wire-guide o, the mandrel being adjustable longitudinally in @and adapted also to be turned therein and secured in place by a set-screw, t. By this construction and combination of parts, the wire-guide and the coiler, when once set in relation to each other, may be removed from the machine and replaced, or may be properly adjusted to receive the wire from the Wheels b and c Without disturbing their relative adjustment. Vhen one of the grooves in cylinder It becomes Worn out-,a new groove may be presented to the Wireguide by loosening set-screw t and turning the mandrel j and cylinder 7s.
The operation of my machine is as follows: The Wire to be coiled is passed between wheels I and c, in groove 71., the wheels being set sufciently near together to cause a strong friction on the wire. As the Wire is drawn forward by the revolution of said Wheels it is pushed through guide o into one of the spiral grooves in cylinder k, and is bent into the shape EDWARD NV. DURKEE. lVitnesses:
