T 0 all whom it may concern:

Be it known that I, AUGUST VILI-IELM S'rARcK, engineer, subject of the King of Sweden, residing in Skolgatan 14, at Sktifde, in the Kingdom of Sweden, have invented certain new and useful Improvements in Automatic Reels for Wire, &c., of which the following is a specification.

The present invention relates to an automatic reel for wire, etc., intended to be used in rolling mills or similar works.

Automatic reels of modern design are generally so constructed that the table which has to carry the reeled wire, by means 'of steam or hydraulic pressure is raised above the reel pins, when the wire ring is to be taken off. By the present invention, on'the other hand, the reel pins are lowered, so that their upper ends are a little below the wire ring thus allowing the same to be freely removed. The present invention is consequently based upon an idea diametrically opposite to that one which characterizes earlier construct-ions.

The invention is illustrated on the accompanying drawings, on which a reel of this design is shown as an example.

Figure 1 shows a vertical section and Fig. 3 a side view of the reel. Fig. 2 shows the reel in plan looking from the top with one half of the wire carrying table removed.

In a support 1, a vertical shaft 2 carries a horizontal table 3, which is intended to carry the ring of reeled wire 4. The shaft and table mentioned are set into rotation from the driving shaft 5, by means of a friction clutch 6 and a pair of bevel gears 7. The reel pins 8 are fastened on the pin-carrying member 9 which can revolve on the ballbearing 10, arranged in the cylinder crosshead 11. The pin-carrying member 9 is set into rotation from the table 3 by means of the pins 8, which extend through the oblong holes 12 radially arranged in the table 3, and besides, the pin-carrying member 9 can be raised or lowered by means of the regulating shaft 13, the levers 14, the links 15 and the cylinder crosshead 11 which is slidably arranged on the support 1 but prevented from taking part in the rotation by the guiding bolts 16, which extend into the slots 17 in the support. The regulating shaft 13 is actuated by the handle 18 through the lever 19 and the link 20, which connects the lever 19 with the lever 21 on the shaft 13. On the same shaft, a crank 25 is fastened,

which by the link 22 is connected with an arm 24 movably fastened to the fork 23. This arm 24 is connected with the hub of the friction clutch 6 in such a way that the friction clutch can be engaged or disengaged by the arm 24. The lever 25 and the link 22 can be adjusted so that the clutch will be engaged, thus starting the reel, just when the pins 8 are raised to their highest position. When the wire ring 4 is completed, by turning the shaft 13, the pins 8 are lowered to their lowest position so that their upper ends are a little below the ring. Meantime, the friction clutch 6 is automatically disengaged by the action of the link 22 and the arm 24. The brake 26, which is carried by the fork lever 27, is pressed against the periphery of the table 3, by means of a treadle 28, which is repelled by a spring 32. The treadle is connected with the brake through the lever 30 and the link 29. By applying the brake, the table will stop almost instantaneously. The levers 14 are provided with extensions in opposite direction, upon which counterweights 31 are arranged, which serve to balance the constant weights of the link 15, the cylinder crosshead 11, the pin-carrying member 9 and the pins 8. Thus, the resistance which has to be overcome by the handle 18, is only the friction, and experience has proved this to be very little. The pins 8, which are fastened pairwise to an iron plate, can be adjusted radially to suit wire rings of different diameters. The plate 33 has to protect the sliding surfaces and the bearings from cinder and heavy dust.

Compared with other constructions, the present invention offers many considerable advantages. As mentioned before, other antomatic rotatory reels of modern design necessitate the use of steam or hydraulic pressure. For this urpose, however, a special regulating cylinder with piston is required, and the whole machinery will be more complicated and expensive. The greatest difliculties with reels of that kind will, however, arise in plants where steam or hydraulic pressure does not exist, because such reels cannot work without arrangements for pressure of some kind, which makes the instalment still more expensive. A reel of the present design can, however, be put up any where as a machine already mounted independently of steam and water, It works scription and the accompanying drawings should only be considered as relating to an example of the invention.

Having thus described my invention, I declare that what I claim, is

1. In an automatic reel for wire and the like, in combination, a shaft,v means for rotating the; same, a vertical standard for said shaft, a table secured to said shaft and rotatable therewith, a bearing for said shaft upon said standard and positioned adjacent said table, a, pin-carrying member slidably arranged on said vertical standard and adapted to be moved relatively to said table,

and. means for moving said member to cause said. pins to occupy alternately operative and inoperative, positions, the length of travel of said. member being greater than the distance between said table and said bearing,

2. In an automatic reel for wire and the like, in combination, a shaft, means for rotating. the same, a vertical standard for said shaft, a table secured to said shaft and rotatable therewith, a bearing for said shaft upon said standard and positioned adjacent said, table, a pin-carrylng member slidably arranged on said vertical standard and adapted to be moved relatively to said table, means for moving said member to cause said pins to occupy alternately operative and inoperative positions, the length of travel of said member being greater than the distance between said table and said bearing, and means for automatically rendering said shaft-rotating means inoperative when said pins are moved into their inoperative position.

3. In an automatic reel for wire and the llke, in combination, a'vertical standard, a shaft mounted therein, means for rotating said shaft, a bearing for the upper end of said shaft upon said standard adjacent the upper end thereof, a table carried upon the shaft at the upper end thereof, a pin-carrying member slidingly arranged 011 said vertical standard and adapted to be raised and lowered with respect to said table, said member reciprocatingly engaging said standard below said bearing and means for reciprocating said member- 4. In an automatic-reel for wire and the like, in combination, a V rotatable shaft, a

vertical standard for said shaft, a table supported thereby, driving means, a clutch interposed between said driving means and said shaft, a pin-carrying member slidably arranged on said vertical standard and adapted to be moved relatively to said table to cause the pins alternately to occupy operative and. inoperative positions and means for moving said member and automatically engaging and disengaging said clutch as the pins occupy their operative and inoperatlve positions respectively.

5. In an automatic reel for wire and the like, in combination, a rotatable shaft, a vertical standard for said shaft, a table supported thereon, driving means, a clutch interposed between said driving means and said shaft, a pin-carrying member slidably arranged on said" vertical. standard and adapted to be moved relatively to said table to cause the pins alternately to occupy their operative and inoperative positions with respect to said table, means for moving said member and a connection between said last mentioned means and said clutch for engaging and dlsengaging the latter in accordance with the movement of the former.

6. In an automatic reel for wire and the like, in combination, a rotatable shaft, a vertical standard for said shaft, a table supported thereon, driving means, a clutch interposed between said driving means and said shaft, a'pin-carrying member slidably arranged on said vertical standard and reciprocatingly mounted with respect to said table, and means for reciprocating said pin carrying member, said means being operatively connected to said clutch, the parts being proportioned and arranged to disengage said clutch. when the pin-carrying member is in its most distant position with respect to the table and to engage-the clutch when the pin-carrying member is in its a-lternate position.

7. In an automatic reel for wire and the like, in combination, a vertical standard, a shaft arranged within said standard, means for rotating the shaft, a bearing forrthe shaft located at the top of said standard, a table secured to said shaft above the bearing, a pin carrying member slidably mounted on the outside of said standard and adapted to be raised and lowered in relation to the table and means for raising and lowering said member.

In wltness whereof I have hereunto set my hand in presence of two witnesses.
