To all t0/wm t ma/ concern.'

Be itknown that I, FREDERICK Fairs- DELL, a citizenof the United Statea, residing at lVorcester, in the county of Worcester and State of Massachusetts, have invented a new and useful I/Vire-Ooiling Device, of which the following is a specification.

This invention relates to a device for coiling wire, capable of general use but par,- ticularly adapted for the making of springs.

The principal objects of the invention are to provide a simple device for this purpose which can be operated by hand with no other apparatus except a viseor the like or which can be placed in a lathe and operated by that if desired. More specifically,` the invention involves the combination with-an arbor, on which the spring or coil is to be wound, with a ceiling tool and af handv tool for operating the ceiling tool itself; and an improved form of ceiling tool adjustable to control the pitch of the coil.

Reference is to be had to the accompanying drawings, in which e f 4Figgl is a plan of a spring ceiling device constructed in accordance with this invention;

Fig. 2 is a. side view; Fig. 3 is an edge view of the wire tool'removed from its support;

Fig.` 4 is a bottom plany view of the. same; Fig. 5 is a plan of one of the'rcmovable ceiling elements fory adjusting the spread of. the,

spring coils; I

Fig. 6 is' an edge view of the same;

Fig. 7 is an'edge view of another plate constituting part of the tool, and` l Fig, 8 is a view showing the operation with all parts of the tool eXceptthe guiding discs, omitted.

This invention is designed for use in smallV shops and in lother places where much Inachinery is not available and for use on small jobs where only one or a few springs'of the same size and character may be required. The device can, beusedin connection with a lathe for turning the arbor,`thehand tool being held stationary asfar as rotation is concerned, but I have shown it herein as being used' Vin connection with a vise V which holds the arbor A in stationary position. It is necessary, therefore, to rotate the coiling tool and this can be done by hand in a very simple manner.

I have shown a tool holder which involves two parts or clamping members 10 a centering and VThe tool holder as I have and .11, these are provided with parallel vperforations located at equal distances from the center and on Vopposite sides of the center. One ofthe perforations Vin each one has a screw thread for receiving the screw threadof a handle 12. l Thescrew threaded portion is of reduced diameter as will be shoulder.v for abuttingobvious, leaving a against the outer surface of the member-l0 or l1." Therefore by turning the two handlesjpthe two clamping members/l0 and 11 can be moved toward vand fronieach other and clamped.` These two handles are knurled to permit of their being used in this wayY and they project in opposite directions, but 'at a distance apart, from the opposite sides of the tool holder itself as shown more clearly in Fig.v l. l I toclamp' the device in position so as to hold the toolthat is to bejused'and also to hold guiding disc 14 in a cylindrical recess at one end of the tool holder.

The other end of the tool holder also has a similar recess 'which is ladapted forreceiving a projection 2O or element of a similar shape connected with the wire coiling tool itself.

called it, is therefore, in the form of a wrench which 'can be used for several purpojses.,v

' The., coiling tojol comprises a plate 21 which `carries the projection l20 that fits in the tool holder and is'held clamped therein when the'tool holder is tightened up.V This plate is providedfwith a screw threaded opening 22 for receiving a v,screw 23.. On

this plate and fastened down tothe same bv,

this screw is a thrust plate l-24 through which vit passes. The plate 2l islprovided with a fixed pin 25 which valsoV passes Vthrough this plate 24.A

I have shown in addition to the plate 24 a series of spacing plates 26, each one with .a

so-called keyhole vslot 27in it, the larger partV of which is for the reception of the screw 23 and the smaller part for the pin 25. These plates are set to produce any desired spacing. i One or more of they plates 26 can be adjusted to register with the first plate 24 if desired, which ordinarily is of the thickness equal to These handlesl are usedl the diameter of the wire of maximum size. j

One or more of the plates 26 are s etso that,`

when the tool is in position on the arbor' they will project over the end of the plate 24 substantially into contact with the arbor. In the drawings I have shown three of these plates inV use and two out of use. If the spring is to be wound more finely only two of them are used, but if wound more coarsely, additional ones are to be added. In Fig. l I have shown two of these spacing plates 26 as set off at an angle merely to keep them where they will not be lost. These two plates vare entirely idle and out of use in the position shown in Fig; 1, the other three being the ones that perform the work.

In use of the device the end of the wire 7 is passed through an open ended slot 30 extending centrally through the end'of the arbor and from thatup through the space 31 between the portion of the'V three plates 26.

This 4holds the end of the wiie in positive position, and the operator simply turns thetool -about the stationary arbor. ,The result of this is to gradually wind the wire on the arbor, the amount of space between the diifereiit coils being controlled by the number of plates 26 which are mounted inthe position for substantially engaging the arbor.

This constitutes an extremely'simple winding device which can be operated by hand andadjusted very conveniently to produce springs of any desired character within reasonable limits. It is easily set up so that it can be used for coiling a single spring if de.- sired and the tool holder, as I have called it, or'hand tool, is lcapable of manyV other uses to hold other metal working tools if desired.

Although have illustrated and described only a single form of the invention I am aware of the factthat modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. rIherefore I do not wish to be limited to all the de tails of construction herein shown and described, or to the particular form of hand tool shown, but what I do'claim is l. As an article of manufacture, `a

' toolfor coiling springs comprising an arbor Von said plate in different planes and fixed Vthereto in two positions, those nearest the flat plate being spaced from the arbor, whereby and a work holder rotatable thereto, a -iiat plate secured tosaid work holder, and a series of spacing plates adapted to be mounted the coarseness of the coil produced can be changed by the fixing of the necessary number of said spacing plates in operative position.

2. The combination with a plate having a centering device for an arbor and a projection by' which it can be clamped for manipulation, a headed screw carried by said plate, a
