RICHARD TITUS, O15 BOWLING GREEN, OHIO.
SPRING WINDEB.
Application filed March 19, 1920. Serial No. 367,206.
To all whom it may concern:
Be it known that I, RICHARD TrrUs, a citizen of the United States, residin at Bowling Green, in the county of 0ml, State of Ohio, have invented a new and useful Spring Winder; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The invention relates to spring winders and has for its object to provide a spring winder comprising a mandrel supporting base adapted to be secured to a support, said base having rotatably mounted in notches thereof, a mandrel, which mandrel is maintained in engagement with said notches by an eye bolt and to provide a handle member for said mandrel which is adapted to receive different sizes of mandrels according to the size of springs being formed. Also to provide said handle with a radially disposed slot for the reception of a holding bolt for holding the end of the spring during a winding operation, the slot forming means whereby the bolt may be removed from engagement with the end of the wire or spring after the spring has been formed.
A further object is to provide a vertically adjustable wire guiding and feeding plate carried by the support which feeding plate is provided with a rotatable cam having its periphery substantially in engagement with" the mandrel so that said cam may be rotated so as to regulate the distances between the convolutions of the spring as the same is being formed. Also to provide said cam with a series of arcuate apertures adapted to be moved until the desired aperture is in registration with an aperture in the vertically adjustable plate so that a pin may pass through said registering apertures and hold the cam against retrograde movement during a spring winding operation.
A further object is to provide the vertically adjustable plate with a bolt, which bolt is provided with a transversely disposed aperture through which the wire feeds to the mandrel, said bolt forming means for frictionally holding the wire as it is fed to the mandrel.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed it being understood that changes in without departing from the spirit of the in vention.
In the drawings,
Figure 1 is a view in side elevation of the spring winder.
Figure 2 is a top plan view of the supporting bracket for the winder.
Figure 3 is a front elevation of the spring winder with the handle removed.
Figure 4 is a perspective view of the vertically adjustable guide plate.
Figure 5 is a detail view of a portion of the operating handle.
Referring to the drawings, the numeral 1 deslgnates a supporting bracket, which bracket is provided with an arm 2, between which arm and the face 3 of the bracket, a supporting member is adapted to be received so that the spring winder maybe supported during its operation. Arm 2 is provided with a set screw 4 adapted to engage the support and the bracket 1 is provided with a set screw 5 adapted to engage the other side of the support at a point out of alignment with the set screw 4 so that the supporting bracket 1 will be securely held. Bracket 1 is provided with upwardly extending spaced flanges 6, which flanges are provided with V-shaped notches 7 which form bearings for the mandrel 8 as the same is rotated. However, to hold said mandrel in engagement with the bearin s 7 during the rotation of the same, an eye bolt 9 is provided in the eye 10 of which the mandrel 8 is disposed. The mandrel is slidably axially in the bearings 7 and in the eye 10 during a spring forming operation. Eye bolt 9 is disposed between the flanges 6 so that it will only be necessary to provide one eye bolt. When it is desired to remove the mandrel after forming a spring the thumb nut 11 of the eye bolt 9 is loosened so that the mandrel will easily slide out of the eye 10 thereof. Supporting bracket 1 is provided with a downwardly extending arm 12, which arm is provided with a centrally disposed elongated slot 13 through which slot and an aperture 14, in a vertically adjustable plate 15, a securing bolt 16 passes.
which apertures and any one of the apertures 7 I the aperture 20 with the wire being regulated by means of a thumb nut 22. Bolt 19 may be disposed in any of'the registering apertures 17 and 18 on either side of the vertically ad- I S as the same is rotated so that the convolu-' justable plate 12 according to whether the spring is bein provided with a right or left hand series 0 convolutions.
The vertically adjustable plate 12 on its outer face is provided with vertically disosed channels 23 through which the wire is ed tothe mandrel 8. Pivotally mounted on a'pin' 24 near the upper end of the adjustable plate 15 is a cam 25 which cam is round and is adapted to have its periphery in substantial engagement with the mandrel tions of the spring will be equally spaced 25 I spacings of the convolutions will accord- '29 which passes through the registerllndg O for varlous sizes of mandrels.
from each other after the spring is formed. By rotating the cam' so that its cam face 26 is increased or diminished in thickness, the
ingly be increased or diminished in distances from each other. -The cam 25 is provided with concentrically arranged apertures 27, any one of which apertures when placed in registration with an aperture 28 in the vertically: adjustable plate 15, receives a pin apertures thereby forming means for h ing the cam against movement during a spring forming operation. 'The cam 25 is provided with a'handle member 30 adapted to be grasped by' the hand of the operator for moving the cam to the desired position. The mandrel 8 has detachably connected thereto an operatin lever 30, which operating lever is provided with an elongated mandrel receivingv aperture 31in which the outer end of the mandrel is held by'means ofa set screw 32. By providing an elongated aperture it will be seen that various sizes of mandrels may beheld by the operating lever, according to the size of spring being formed, thereby obviating the necessity of providing various sizes of handles Thehandle 20 is also provided with an elongated aperture 33, in which aperture is slidably mounted a headed bolt 34. The head bolt near its outer end is provided with an aperture 35 through which the end 36 of the wire 21 is a spring forming operation. By disposing passed and clamped against a washer 37 I when the thumb nut 38 is set, thereby securely holding the end of the spring during the bolt 34 in the elongated aperture 33, it will be seen that when it is desired to release the spring it will only be necessary to loosen the thumb nut 38 and allow the bolt to drop into the lower end of the, aperture 33, thereby allowing the end 36 of: the spring to come out of engagement with. the aperture 35, as shown in Figure 1; To emove the spring after the same haslbeen formed, the bolt 9 is loosened the wire 21 severed adjacent its upper end and the mandrel and handle removed from the body of the machine, then the holding bolt 34 is loosened thereby allowing the spring which has been formed to be removed from the mandrel. By this construction it will be seen that the mandrel will not have to be moved from the oper= ating lever to remove the spring from the mandrel after thesame has been formed.
The cam 25 is provided with a segmentally shaped notch 39 adapted to be thrown into engagement with 1 and in registration with the'convolutions ofrthe springs when it is gesilred to remove the spring from the manre V The invention having been set forth what is claimed as new and useful is:-
A spring winding machine comprising a mandrel, a supporting bracket, said mandrel being rotatably and slidably mounted in bearings of the supporting bracket, means for feeding wire to said mandrel as it is rotated, .a round disc cam plate pivoted to said bracket adjacent the mandrel and forming means for spacing the convolutions of the spring as the mandrel is rotated, said disc cam plate being provided with a central pivotal point, said disc cam plate being provided with concentrically arranged apertures, said apertures being adapted to register with an aperture in the bracket, a removable pin passing through said registering apertures for holding the cam against rotation after an adjustment thereof and during a spring winding operation.
In testimony whereof I have signed my name to this specificationin the presence of two subscribing witnesses.
