MACHlNE FOR MAKING COILED SPRINGS.
SPECIFICATION forming part of Letters Patent No. 261,319, dated July 18, 1882,
7 Application filed April 17, 18S2. (No model.)
To all whom it may concern:
Be it known that I, JoHN DUBELMAN, of' Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Machines for Making Coil- Springs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, which formu a part of this specification. The nature of this invention relates to certain new and. useful improvements in the construction of machines for the manufacture of thatclassofsirin sknown ascoilors iral l g P certainty and rapidity and of any required closeness or loosenessin the coils, as more fully hereinafter described.
Figure l is a perspective view of the improved machine. Fig.2 is an end elevation of the coiling-wheel andspindle with various parts removed, and Fig. 3 is a vertical central section of the spreader-bar.
In the accompanying drawings, Arepresents the standards of the machine, which carry the operating parts, said standards rising from the bed B, which is provided with the prolongation G. The main driving-shaft D runs in suitable boxes, E, secured to the standards, and is driven from any suitable source of power. Upon this shaft is secured the gearpinion F, which engages with the spur-wheel Gr, WhlCh is secured to the shaft H, journaled in boxes I, secured between the standards A. Upon this shaft H'is secured the pinion J, which engages with the pinionKupon the shaft L, journaled in boxes M N, which have a vertical movement between the standards A upon the vertical guides O. The box M is raised or lowered, as occasion may require, by means of the screw P, while the opposite end of the shaft and its box N are raised or lowered by the operation of the machine, as hereinafter explained. Upon the outer overhanging end of the shaft L is the heavy steel-faced wheel Q. The shaft H is threaded, as shown, and terminates in a socket, S, to receive the end of the spindle B, which is secured in said socket by the set-screws a. This spindle is made removable, so that spindles of different sizes may be employed in manufacturing springs of larger or smaller diameters.
T is 'an arm or bracket secured to the standard A, and upon its free end is journaled a groove-Wheel, U.
V is a box sleeved upon the shaft L and lat-' H, but without contact therewith, and terminates in a slotted guide, X, through which the arm Y has a reciprocating motion. The inner end of this arm Y terminates in a tongue, A, which is designed to engage at certain times with the thread upon the shaft H, and by means of this engagement the arm with its attachments is drawn toward the rear of the machine until the tongue is allowed to drop again. The opposite end of this arm Y is pivotally secured to the rod B, which has a reciprocating motion in the boxes G, secured upon the top. of the supports D, and upon this arm is a coilspring, E, adapted to retract the rod and the arm Y when the tongue A has dropped out of engagement with the threaded portion of the shaft H. To the opposite end of this arm B are secured the spring-jaws E made substantially in the form shown, and these are projected and retracted with the reciprocation of the rod B.
F is abracket, carrying a spreader-bar, G, so pivoted that on the projection of the rod B it will spread or divide the spreaders E as the contracted parts thereof pass the suspended spreader until such projection brings the enlarged space H forward to the point-occupied by the spreader, when the springs will'assume their normal position; and in the retraction of the bar B the spreader will be raised up until in the retraction of the jaws E E it will drop into the position shown in the drawings.
To the end of the rod B is hinged the stop I, which, in the projection of the rod B, depresses the lever J, fulcrumed at c, and raises dle.
the opposite end of said lever, which is provided with a lip, 01, for the purposes hereinafter described. This stop, on the retraction of the rod B, will swing upward, its point resting lightly on the top of the lever J until it falls off the end thereof, when it will assume the position shown in the drawings, and the spring 0, under the lever J, will elevate that end of it.
It is important in the construction of this machine that the position of the shaft H and its spindle R shall not be in the vertical plane of the axis of the shaft L, but to one side thereof, as shown in Fig. 2, and the adjustability of the parts is such as to allow springs of larger or smaller diameter or of larger or smaller wire to be made by simply changing the spindle B and vertically adjusting the box M to correspond.
In the operation of the machine, the box M will adjust itself by the interposition of the wire in the process of manufacturing springs. The size of the wire and the diameter of the spring being determined upon, a spindle corresponding to the internal diameter of the spring is secured in the end of the shaft H and the box M adjusted to the required thickness of the wire, the cogs on the pinions being sufliciently long to allow of such adjustment. The end of the wire is fed over the spool U and over the spindle It, and as it passes under the wheel Q it raises the box N to a level with the box M, and the weightof the wheel bends the wire to conform to the shape of the spin- As the coils are formed upon such spin dle the projection of the rod B is caused by the tongue A engaging with the thread upon the shaft H. This projection causes the stop I to depress the end of the lever J and force its tongue between the coils of the wire to spread them, and the greater or lesser spread between the coils will be obtained by using a broader or narrower tongue, d, which may be done at will either by conforming such tongue to slip onto the end of the lever J or having a number of such levers with different-sized tongues, one of which may be inserted in the machine when required for use. By using levers of different length the length of open coil can be easily altered. This projection also of the rod B causes the spring-jaws to likewise project and be spread apart by the spreader Gr until such jaws will embrace the two opposite sides of the spindle B with the spring upon it. As soon as thepiece of wire fed upon the spindle Ris completely coiled it will, by reason of its engagement with the tongue (1 of the lever J, be drawn out from under the wheel Q, and the latter, dropping down by its weight,willnowlowerand disengagethetongue A of the lever Y from the convolutions of the thread on shaft H. The disengagement allows the spring E to retract the shaft B, the jaws E E thereby pulling the finished coil from the templet 1%. During this retrograde movement the spreader-bar G, being free to swing forward, is raised out of the way without spreading the jaws. The coil withdrawn from the templet B; is held loosely enough by the jaws E E to fall out and down into the tempering-bath. If not, the re-opening of the jaws at the beginning of a new operation will allow them to do so.
The guide X and yokeW are kept in proper vertical position by a pin, l, moving in a longitudinal slot, at, in the bed B.
What I claim as my invention is 1. The combination, with the rotating spindle R, of the heavy wheel Q, secured to a shaft mounted in two bearings, one of which is adjusted by a set-screw and the other adapted to have a free vertical movement, substantially as described.
