TABLE FOR HOOPING COILED VIETAL.

SPECIFICATION forming part of Letters Iatent No. 643,472,dated February 13, 1900.

Application filed December 6,1899. Serial BT03391378. (No model.)

To LLZZ whom t may concern:

Be it known that I, WILLIAM A. COWLES, a citizen of the United States,residing at Ansonia, county of New Haven, State of Connecticut, have invented a new and useful Table for Hooping Coiled Metal, of which the following is a speciiication.

My invention has relation to the preparation of coiled sheet metal for handling and for shipment.

In producing sheet metal in rollingmills the metal as it comes from the rolls is coiled upon a mandrel, and it is necessary quite frequently to re-coil the strips of metal after the various operations that may have 'been performed upon them. After each ceiling operation the strip of metal is removed from the mandrel upon which it has been coiled, and the strips are prevented from uncoiling by means of hoops or bands,which are slipped over them while they are held tightly. My present invention has nothing to do with the coiling of the metal, but relates only to the hooping of the coils after they are removed from the mandrel. This operation as it has heretofore been performed in brass-mills has either required the services -of two men or else has necessitated the stoppage of the rolls while a coil was being hooped, as it is impossible for one man to hold and hoop a coil of metal and at the same time to start another coil on the mandrel.

YVith the above conditions in view my in# vention has for its object to provide a table and holding device upon which each coil of metal may be placed when removed from the mandrel and by which it will be held from uncoiling while the operator starts a second coil on the mandrel, the operator having ample time to hoop each coil whileV the next coil is running through the rolls, thereby effecting an important saving in the cost of production.

` In the accompanying drawings,fo1ming part of this specification, Figure 1 is a front elevation of my novel hoopingtable complete;

Fig. 2, a plan view thereof; Fig. 3, an end elevation as seen from the left in Fig. 2, one of the leg-sockets being in section; and Fig. t is a section on the line 4 4 in Figs. 1 and 2.

'other one.

10 denotes the bed or table proper, and 11 It will of course be obvious that my novel table must be fitted to sustain heavyweights and to withstand rough usage, while at the same time unnecessary Weight is to be avoided. In practice I have made the table proper of brass and the legs of iron, although of course it is wholly immaterial so far as the principle of my invention is concerned of what special metals the parts are made. The legs are shown as provided at their upper ends With anges 12, which fit closely in sockets 13, said sockets being bolted to the underside of the table.

In use the operator places each coil as he takes it from the rolls or after a scouring or polishing operation and places it upon the table, Where the coil is retained by a holdingplate 14, preferably curved, as shown, in connection with holding-pins 15.

16 (see dotted lines, Figs. 1 and 2) denotes hoops ready tobe placed upon the coils, which are shown as hanging from a suit-able holder 17. The holding-plate, which should be narrower than the coiled strips of metal that are to be hooped, may be conveniently adj usted vertically or removed and replaced by an'- I have shown this holding-plate as adjustable on a retaining-plate 18, which is bolted to the table and is provided with vertical slots 19 and a vertical recess 20,which receives a corresponding projection 2l upon the holding-plate.

22 denotes a guide-pin rigidly secured to the table and passing through the holdingplate,and 23 denotes bolts which pass through the vertical slots and engage the holdingplate, the heads of theboltslyingon the back of the retaining-plate and acting by engagea ment therewith to lock the holding-plate at any required vertical position relative to the retaining-plate that may be most convenient in connection with any special width of coils of metal that may require to be handled upon the table. It will be apparent that the guidepin and the engagement of projection 21 onthe holding-plate with the vertical recess in the retaining-,plate will keep the holding-plate steady at any adjustment at which it may be placed. The holding-pins are carried by a cross-head 24 and extend upward through guides 25 and through the table, their upper ends lying flush with the surface of the table when at the lowered position, as in Fig. 3, and extending some distance above the table when at the raised position, as in Fig. 4. Guides 25 are shown as made integral with a web 26, ears 27, and a plate 28, which is bolted to the bed. The cross-head and holding-pins are carried by a rod 29, which is adapted to slide vertically in a guide 30, carried by a cross-piece 3l, which is bolted to the front legs. The upper end of rod 29 is shown as threaded and as passing through the cross-head, nuts on the threaded end on opposite sides of the crosshead locking the parts rigidly together. A spring 32, which bears upon guide 30 and upon the cross-head, acts to retain the latter and with it the holding-pins at the raised position. At the lower end of rod 29 is a footpiece 33, by which the rod, cross-head, and holding-pins may be drawn downward against the power of the spring.

34 denotes a locking-lever which in form is a bell-crank lever and is pivoted between ears 27 under the table. One arm of this locking-lever is provided with a locking-lug 35, which is adapted to engage the cross-head to retain the latter and the holding-pins at the lowered position, as in Fig. 3, and the other arm is provided with a handpiece 36 for convenience in manipulating it in use.

37 denotes a spring one end of which is secured to one arm of the locking-lever, the free end bearing against the under side of the table and acting to retain the locking-lever in such position that lug 35 will engage the cross-head when the latter is moved down and will retain the lug in the engaged position until the cross-head is released by pressing down upon handpiece 3G.

I have shown the table as provided with a holder 17 for hoops, so that they will be convenient for use. This holder is simply a rod adapted to oscillate and to slide in bearings 39, bolted to the underside of the table. The outer end of the holder is upturned, as at 40, to enable it to retain a quantity of hoops in place, and the holder is retained at its operative position, as in full lines in Figs. l and 2, or at its inoperative position (see dotted lines, Fig. 2) by means of lugs 41 and 42 upon the rod. These lugs are shown as cast in a single piece, which is secured to the rod by a pin 43. (See Fig. 4.)

44 and 45 denote spring locking plates which are secured to bearings 39 and are adapted to be engaged, respectively, by lugs 41 and 42. Vhen the holder is in its operative position, lug 4l will be engaged by spring locking-plate 44, and the holder will be retained in place thereby. Should it be desired for any purpose to move the holder out of the way, it may be given a quarter-turn and pushed inward under the table, as indicated by dotted lines in Fig. 2, and may be locked in this (its inoperative) position by the engagement of lug 42 on the holder with spring locking-plate 45 under the table.

The operation,which it is thought will be clearly understood, is briefiy as follows: The

operator places the coil of metal that is to be hooped upon the table, pressing it against the holdin g-plate and releasing the cross-head by means of handpiece 3G, allowing spring 32 to raise the cross-head and holding-pins, the latter passing on the outer side of the coil of metal opposite to the holding-plate and retaining it against uncoiling. The hoops are made just large enough to go easily over the coils of metal. The instant a hoop is in place the operator presses down upon the footpiece and withdraws the holding-pins, when the coil of metal will instantly expand and fill the hoop tightly. The operator may of course retain the holding-pins at less than their normal height by keeping his foot upon the footpiece. The instant the cross-head has reached its lowered position it is locked there by the engagement of lug 35 therewith, thus leaving the entire front of the table clear for the removal of the hooped coil of metal and for the placing thereon of another coil of metal to be hooped.

Having thus described my invention, I claiml. In a device of the character described the combination with a table and a curved hold ing-plate, of vertically-movable holding-pins which when in the raised position coact with the holding-plate to prevent a coil of metal from uncoiling.

2. In adevice of the character described the combination with a table and a curved holding-plate, of vertically-movable holding-pins whose upper ends lie Hush with the table at the lowered position and extend above the table at the raised position, for the purpose set forth, a cross-head by which they are carried, a spring for normally holding said cross-head at the raised position, and afootpiece whereby said cross-head may be lowered against the power of the spring.

3. In a device of the character described the combination with a table and a curved holding-plate, of vertically-movable holding-pins, a cross-head by which they are carried, a spring for raising the cross-head and holdingpins, means for lowering the cross head against the power of the spring and means for locking the cross-head at the lowered position.

4. In a device of the character described the combination with a table and a curved holding-plate, of vertically-movable holding-pins, a cross-head by which they are carried, 'a spring for raising the cross-head and holdingpins, means for lowering the cross head against the power of the spring, a lockinglever one arm of which is provided with a handpiece for convenience in operation and the other with a lug adapted to engage the cross-head at the lowered position, and a IOO IIO

spring acting to retain said locking-lever in the engaging position.
