(Cl, 242-85) aalst .1,5 impartan .and it. :is desirable t0 .have .a ssmpact machine,it"is essential that the device for supporting the reels and guiding the Vstra/nds as they -are being unreeled should be so designed that the reels may be grouped in -a small area and "that the device does not require much .space @admise 0r axially 0f the reels .lt is als@ ssssatial .that full reels may be readily and eas/ ily inserted in the device and emptyreels remvedtherefrom, and 'that the wire may be withdrawn or unwound from the reels at a high rate of speed and be free from kinks.

It is an object of the present invention to provide an improved device for supporting reels and for guiding strands unwound therefrom,

In one embodiment of the invention, a plurality of reels are supported in a row on a supporting plate having hooks for support on sloping legs of a chair.

A cylindrical tubular guard surrounding each reel limits the radially outward whipping movement of the unwinding strand and a guide plate having a circular aperture for each reel concentric with the axis thereof and positioned beyond the end of the reel to further restrict the radial outward movement of t-he strand as it is being unwound from the reel.

A complete understanding of the invention may be obtained from the following detailed description of a dereeling device forming a specific embodiment thereof, when read in conjunction with the appended drawings, in which Fig. 1 is a side elevation of a dereeling device forming one embodiment of the invention, and

Fig. 2 is a rear elevation of the device taken along line 2 2 of Fig. 1.

Referring now in detail to the drawings, there is shown therein a machine 10 for winding selected ones of

Wires

11, 12 and 13 of a lled type, that is, coils of a type having sheets or layers of insulating material, such as, for example, paper, cellulose acetate, cellulose acetate-butyrate, or the like, between wound layers of the wire. The

wires are supplied by a strand supply unit 16 mounted detachably on an operators chair 17. The unit 16 includes a base plate 18 having

hook portions

19 and 20 which hook over diverging

chair legs

21 and 22 inclined substantially to the horizontal. The hooks lock the base plate on the

legs

21 and 22 in a somewhat upwardly facing position in which the plate slopes downwardly, as viewed in Fig. l, from the rear leg 21 to the front leg 22 so that the wire 11 travelling to the arbor 14 clears the wire 12 and both wires 11 and 12 clear the wire 13.

Posts or arbors 31 of the type shown in D. H. Blair Patent 2,678,782, issued May 18, 1954, for Strand Dereeling Device, are mounted rigidly on L-shaped brackets 35 welded to the plate 18, and mount wire supply reels 38 thereon.

The chair. ,1.71.1215 a Seat-,51 `fastened nasale-irons 52 eirinlsd .ts @Quilting brackets 5.3 ,Supreme-1 `risid1y by tw'o-` angle-iron legsw54`and two transverse angle-irons 55 ixed to the

legs

21, 22 and 54. Leg braces 56 also are provided, and a back rest 57 is secured to the rear angleiron 52. The extreme incline with respect to the horizontal of the

legs

21 and 22 permits the unit 16 to be substantially under the seat 51 and inside the lower ends of the

legs

21 and 22 so that the weight of the unit 16 with the reels 38 of wire have no tendency to tip over the chair. This slope or incline is made feasible by the irons 55 which form rigid Ts with the

legs

21 and 22. The

hooks

19 and 20 have short underhanging lips 61 to lock the plate 18 to the

legs

21 and 22, which incline or converge upwardly toward one another so that the weight of gravity presses the plate 18 down on the

legs

21 and 22 to lock it thereon. The hooks19 and 20 are at such angles relative to one another and t-he longitudinal axis of the plate 18 that the hooks automatic-ally abut the sides of the

legs

21 and 22 and are allowed to slide down thereon so that the lips 61 enter under the angle irons. The upper end of the hook 20 is at or above the level of the lower end of the hook 19 when the hooks abut the angle-irons. Hence, pivoting of the plate is prevented. The entire unit 16 may be removed from the chair by sliding the plate 18 upwardly along the

legs

21 and 22 from the shown position of the plate 18 until the short lips 61 can clear the -

legs

21 and 22 and then lifting the unit oir the

legs

21 and 22. A post 65 fastened rigidly to the brace 56 for receiving a reserve spool of wire which also serves as a stabilizing weight to balance the weight of the loaded unit 16.

The above-described device is very stable, may be supplied with the loaded reels without interrupting the operation of the machine 10, requires little more space than the chair 17 itself and the unit 16 may be removed from the chair in a matter of seconds for repair or replacement.

It is to be understood that the above-described arrangements are simply illustrative of the application of the principles of the invention. Numerous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.

What is claimed is:

l. A dereeling device, which comprises a frame having a pair of inclined diverging legs on one side thereof, and a strand supply unit having inclined diverging hooked ends conforming to the legs of said frame and designed to rest on and hook under said legs in response to movement of said unit in one direction and to be disengaged from the legs in response to movement of the unit in the opposite direction.

2. In a strand dereeling device, a frame including a platform, a pair of legs secured to one side of the platform, a pair of T-shaped legs secured at one end of the top of the T to the platform and at the other end of the top of the T to the first-mentioned legs, the stem portions of the T-shaped legs being inclined with respect to the horizontal and diverging downwardly, and a strandsupplying unit having wide hook portions on the ends thereof designed to hook under and rest on the T-shaped legs, said wide hook portions being at such an angle relative to one another that the hook portions engage the stems of T-shaped legs at such points thereon as to hold the unit in a position sloping forwardly and downwardly on the T-shaped legs.

3. In a strand dereeling device, a frame including a platform, a pair of legs secured to one side of the platform, a pair of T-shaped legs secured at one end of the top of the T to the platform and at the other end of the top of the T to the lirst-mentioned legs, the stem portions of the T-shaped legs being inclined with respect to the horizontal and diverging downwardly, and a strand-supplying unit having opposed hook portions on the ends thereof designed to hook under and rest on the T-shaped legs.

4. In a strand dereeling device, a. movable frame including a platform, a pair of legs secured to one side of the platform, a pair of T-shaped legs secured at one end of the top of the T to the platform and at the other end of the top of the T to the first-mentioned legs, the stem portions of the T-shaped legs being inclined with respect to the horizontal and diverging downwardly, a strand-supplying unit having wide hook portions on the ends thereof designed to hook under and rest on the T-shaped legs, said wide hook portions being at such an angle relative to one another that the hook portions engage the stems of T-shaped legs at such points thereon as to hold the unit in a position sloping forwardly and downwardly on the T-shaped legs, and means for supporting a reel on the first-mentioned legs to balance the load on the frame.

5. A strand supplying unit detachably mountable on a chair having a pair of legs inclined with respect to the horizontal and diverging downwardly, which comprises a plurality of strand supporting stands, an elongated base plate for supporting the stands thereon in a row, and wide hooks on the ends of said base plate in diverging relation to each other corresponding to that of the legs on the chair for engaging the legs at different elevations to hold the base plate and the stands thereon in a position sloping forwardly and downwardly relative to the chair.
