SPECIFICATION forming part of Letters Patent No. 297,010, dated April 15, 1884.

Application tiled December 28, 1883. (No model.)

To @ZZ w/Lom/ it' may concern:

Be it known that I, JOSEPH M. ROBINSON, of Brooklyn7 in the county of Kings and State of New York, have invented a new and useful Improvement in Barrel-Shaping Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part or" this specification.

My invention relates to the apparatus employed in steaming and shaping casks or barrels; and the object of my improvement is to facilitate drawing in and shaping the steamed staves to form the cask, preparatory to heading the same.

It consists in combining with the steamingbox a cord or wire loop or band adapted to'be slipped over the upper free ends ofthe staves after they have been set up around one head of the cask, the loop being arranged to be so drawn and tightened by means of a screw or equivalent mechanical device, operated from the outside of the box, as to bend in and draw the staves together after they have been softened by the steam, and thus form and unite them into the shape required in the finished eask.

In the accompanying drawings, Figure lis a vertical central section through the improved steaming-box; Fig. 2, a transverse sectionV in line x x of Fig. l, and Fig. 3 a view in perspective of a winding-drum constituting an equivalent for a traveling nut in drawing up the forming-loop.

A represents a steaming-box, of any approved construction, adapted to receive the shook after the staves S S have been set up in position around the lower head, T.

A is the steam-supply pipe for the box, and A the exhaust-pipe.

B is a strong lloop or iiexible band-preferably oi wire-long enough to encircle the free ends of the staves in the shook when set up. The two ends of this loop are brought near together and passed each around a friction-roller, C, Fig. 2, journaled at the side of the box on a level somewhat below t-he upper ends of the staves, and are led out to a traveling nut, 5o D, whichis fitted upon a screw, E, mounted to rotate in a lateral recess or chamber, F,

formed on the side of the steaming-box. The rotation of the nut is prevented by the lateral longitudinal guide-strips d d, upon which it is free to traverse. The outer end or shank of the screw E extends outwardly through a suitable gland or stufng-box in the end of the chamber F, with a steamtight joint, and terminates in a head, G, yadapted to be engaged by a rod or lever, II, or which may be fitted with a crank, to facilitate its rotation.

As an equivalent for the traveling nut upon the screw E, a rotating drum or pulley, K, (see Fig. 3,) may be mounted in the lateral chamber F, and the ends of the loop or band B secured thereto, so that by rotating the drum the cord or wire constituting the loop, being wound up thereon, will be tightened and contracted about the staves, as required. The drum may be rotated by a crank tted upon 7o the end of its axle or shaft, made to project outside ofthe chamber F, and its reverse movement in winding the loop be prevented by a pawl and ratchet.

In the use of inyimproved forming apparatus, the straight staves of the cask are set up in the usual manner around the lower head and confined by means of a band or hoop, L, and the shook thus set up is placed within the steaming-box A. The flexible formingloop SO or contractile band B is then passed over the upper ends of the staves S S, to encircle and embrace them. The box is then closed and steam admitted thereto through the pipe A until the staves have became suiiiciently soft- 8 5 ened to readily bend. The loop B is then drawn up or tightened around the staves by a rotation of the screw E, actuating the traveling nut D, to which the ends of the loop are secured, or by a rotation of the drum K, if that 9o be employed. As the nut D moves outward or the drum K rotates, the loop B, closing and contracting around the staves, will draw them closely together edge to edge, their form producing, when they are thus united, the proper bulge or Outward curvature required in the finished cask. Vhen the staves are thus fully drawn up and tightly closed together, they are confined by means of a clamping-hook until the cask is removed from the box and nally roo hooped in the usual manner.

It is evident that various devices adapted to be operated from outside the steaming-box may be employed for contracting the loop B around the stavcs after they are steamed, and I contemplate the use in this connection of any of these well-known mechanical appliances.

Heretofore the shook, after being set up and steamed7 has been removed from the steamingbox7 in order to draw up and bend and close the staves together. My improved method of bending and closing up the staves Within the steaming-box obviates all the difficulties which attended the pld process, because ofthe rapid cooling of the staves aftertheir removal and the loss of time attendant upon the opening and consequentcooling ot' the box required to ascertain whether the staves have attained a proper condition for removal, or in waiting a longer time than necessary to insure positively such aproper condition. By closing the staves within the box I am enabled to perform the operation at the earliest possible moment7 and the operation having been commenced it may be continued Without interruption or failure and Without any unnecessary delay in each case until fully completed.

I claim as my inventionl. The method herein described of forming casks, which consists in submitting the straight staves, when set up around one of the heads of the cask, to the action of steam in a steamingbox, drawing and completely closing the softened staves together to form the cask While still inclosed Within the steaming-box, and binding and securing the free ends ofthe closed staves in position before removing the Cask from the box.

of a flexible contractile loop or band fitted within t-he box in position to encircle the staves of the shook, and arranged to be contracted by suitable mechanical devices oper-`
