UNITED STATES HERBERT M. DANIELS, OF'NAZARETH, PENNSYLVANIA.

TOOL FOR FdRMING SPIRAL SPRINGS.

Specification of Letters'Patent.

' Patented Feb. 2, I909.

' Application filed October 12, 1908. Serial No. 467,270.

The primary object of my invention is to provide a tool which is especially adapted for use in cases of emergency, and is so constructed that it may form part of an ordinary tool kit.

Another object is to. so provide for the adjustment of parts that springs of many sizes and indefinite lengths may be formed.

A further object is to provide means for guilding the wire and correctly spacing the 001 s.

With these objects in view the invention consists in the improved construction and arrangement of parts which will be more fully described in the accompanying specifi cation and particularly pointed out in the appended claims.

In the accompanying drawings wherein I have shown one embodiment of my improved tool, Figure l is a side elevation thereof. Fig. 2 is a similar View of the opposite side. Fig. 3 is a top plan view. Fig. 4 is an end elevation, and Fig. 5 is a vertical section on line w-m of Fig. 1.

Like reference characters throughout the several views designate like parts.

Referring to the drawings 1 indicates'the body or coiling head of my improved tool, and 2 the operating handle thereof. The coiling head 1 is preferably formed of hardened. steel, and is provided on its upper surface with a V-shaped recess 3 which extends substantially one-half of the depth of the head thereby forming the opposed jaws 4. Between the jaws thus formed is adapted to be engaged the rod 5 which may be supported in any suitable manner.

The coiling head 1 is bifurcated as shown at 6 for the accommodation of the hooked end 7 of a clamping member7, said hooked end of the clamping memberbeing adapted to engage the rod 5 and secure the tool thereon. To provide for the coiling of springs of various diameters, this clamping member is adjustable upon the head to accommodate various sizes of rods.

Any preferred means may be employed for adjusting the member 7, but I have shown for this purpose a vertical slot 7 through which extends the screw threaded bolt 8 secured in the body of the tool. Upon the end of this bolt is threaded the wing nut 8' which bears against the clamping member and se cures the same in its adjusted position. In one face of the coiling head is formed the horizontal recess 9 in which is adjustably secured the member 10 the purpose of which will now be described. This member is secured to the head in a manner similar to that employed to se ure the clamping member thereon, and comprises the horizontal portion 11 slotted as at 12 to receive the'threaded bolt 13 provided with the wing nut 13 which will secure the member 10 in the recess 9 in its adjusted position when screwed up on the same.

The outer end of the member 10 is formed with the enlarged portion 14, the inner face of which is beveled as at 15 approximately at the same angle as the inner surface of '-the jaws 4. The upper edge of the portion 15 is also beveled at an acute angle 15 across the entire width'thereof, and is of about the same-depth as the recess 3. The meeting edge of the two beveled surfaces is in constant engagement with the wire and thus moves the tool along the rod 5 as the wire is coiled around the same.

It will be noted that a portion of one end. of each of the jaws 4 is cut away as at 4, 4. In the space 4 thus provided is adapted'to be received the enlarged end 14 of the spacing bar, the jaw forming a stop for the same. By this means a large variation in the number of coils is obtained, and the space 4 allows the wire to contact with the spacing bar at all times. I

The guide plate 16 removably secured to the side of the head by means of the wing nut 18 and grooved on its under surface as at 19, is adapted to at all times yieldingly secure the wire 20 to the side of the tool, and also to provide for the proper winding of the wire around the rod 5. This groove is deep enough and, wide enough to receive various thicknesses of wire.

The space between the coils is determined by adjusting the member 10 with relation to the vertical axis of the wire. This space will equal the distance between the point of My improved tool is designed to obviate engagement of the wire with edge of the beveled surfaces and its point of contact with the rod 5 It will thus be seen that a greater or less number of coils is obtained by adjusting the member 10 outward or inwards.

The operation of the device is obvious. Therod 5 is placed between the jaws t and clamped therein by means of the clamping member 7. The necessary thickness of wire is obtained and one end attached to the rod. The wire is now placed beneath the guide plate 16 and the spring is ready to be coiled.

This is easily and quickly accomplished by grasping the handle 2 and turning the tool. around and along the rod.

It will be seen that I have produced a tool which is extremely cheap and simple in construction, and which may form part of the tool kit whereby it may be readily transported when necessary. My invention is more especially adapted for repair work. As is often the case small spiral springs become broken or unfit for further use, and new ones cannot be obtained without great delay. this delay and to form spiral springs of any required size and of indefinite length in a very short space of time.

While I have shown what I believe to be the preferred form of my invention, it will of course be understood that various minor modifications can be resorted to within the scope of the claims without departing from the spirit or'sacrificing any of the advantages thereof.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
