MACHINE FOR CUTTING HEAD-LININGS FOR BARRELS.

SPECIFICATION forming part of Letters Patent No. 350,697, dated October 12, 1886.

Application filed November 30, 1883.

To all whom it may concern Be it known that I, LoUIs REED, of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improved Machine for Cutting Head-Linings for Barrels and Dressing Hoops, of which the following is a specification.

This invention is especially designed for cutting head-linings for barrels out of strips of wood such as are used for making hoops but by altering the cutters it may also be used for dressing hoops or other analogous uses.

I11 the annexed drawings, making part of this specification, Figure l is an end view of the machine,showing the cutting mechanism. Fig. 2 is a view of the other end, showing the driving mechanism. Fig. 3 is a plan view. Fig. 4 is a vertical section through the cutting mechanism, and Fig. 5 is a plan and sectional view of one of the cutters.

The same letters are employed in all the figures in the indication of identical parts.

A is the frame, adapted to support the several working parts of the machine.

B is the driving-pulley, to which the power is applied from any suitable prime mover. A pinion, B, on its shaft engages the pinion 13 on the shaft of one of the feeding-rolls, while the other is hung on the driving-shaft, and the same pinion engages the intermediate wheel, B, which drives the twin pinions 13* B on the shafts of another set of feedingrolls.

O is a rotating and independently-actuated cutter-head carrying two knives, G,which are formed, as shown in Fig. 5, with edges to cut the strip into several narrow strips, the out ters separating such strips by cutting through the piece. The side ribs of the cutters O are made wide enough to cut away entirely the sides of the strip intended to be acted upon. This is a matter of considerable practical importance, as otherwise a narrow ribbon of tough wood would be formed from the edge of the strip, which would coil about the mechanism and impede the action of the cutter-head and other parts of the machine. By this means I not only produce a head-lining better in form than any other known, but form a series of them and separate them at the same time, turning out several of the finished articles completed at a single operation.

Serial No. 113,147. (No model.)

The strip to be cut (represented at F) is fed along the surface of a concave table, D, passing first between the two rollers E E, the upper one being corrugated so as to crimp the upper face of the strip by breaking the continuity of its structure and causing it to curve permanently and bend readily to tit the curvature of the cask to which it is to be applied.

G is a curved arm, hinged at one end and having its other and free end resting 011 the surface of the strip to hold it down rigidly on the face of the table while being fed to the cutters. This arm is heavily loaded, and the weight is adiustably attachedto the arm. The point carries a friction-roller which bears on the strip. Another set of rollers, E E is an ranged to engage the strips as they pass away from the knives, and further crimp them and hold them in place. These rolls are posi tively actuated, the first set by the pinious B B and the second set by the pi nious B B In order that the upper rolls may bear the strip more closely against the face of the table they are set forward toward the cutter, so that they bear upon the strip over the face of the table on one side after the strip has passed over the lower roll and on the otherbcforc it has reached the latter. To increase the pressure of these rolls, they have theirjournals at one end loaded with the weights E E suspended by levers and links, as shown in dotted lines in Fig. 1, the journal-caps having the necessary play to permit such weights to act on the rolls.

W'hen the strip F is passing under the rotating knives C, it is very important that it should be held very firmly on the bed, in order that the cut may be smooth. To this end the bed is slightly elevated at that part, and that the knives may not beinjured this raised part is made of soft n1eta-l,preferably of a Babbit metal block, H; but as this block is soft and rapidly worn away as compared with other parts of the surface of the table, I make it to fit into a hole. in the table and support it upon a set-screw passing through the stirrup H. By means of the set screw the block may be adjusted from time to time, and when it is Worn out it may be withdrawn and a new one very readily substituted. As the knife 0 has ribs or projections which are intended to cut entirely through the wood and to cutit all away,

exceptthe hoops or strips which are formed by the outline of the cutters, it is essential that the block H shall be of a composition having such softness that the points of the ribs of the cutters may cut shallow channels in the face of the block, so that the cutters may pass entirely through the wood, and yet it must not be so soft as to be too readily worn away, for when the channels are wider than the cutters they will not make a clean cut, the edges of the channel forming, with the edges of the cutters, shears which entirely cut away the wood, leaving the strips which are to form the head-linings or hoops smooth on their faces. I have found Babbitt metal suitable for this use. \Vhen a block is first inserted, the knives are turned by hand until slight channels are formed in the face of the block,which is gradually raised by the set-screws. As this will dull the knives, they will require to be sharp ened or replaced by duplicates. As the channels become worn,the block must be raised and a new'face formed after the old one has been chipped off by ch'isels. The cutters are hung on the shaft I, and independently rotated by a belt 011 the pulley I. The shaft extends outside of the frame A,so as to overhang the cutters, and to steady their action the outer end of the shaft is supported upon the bracket 1.

For dressing hoops, knives of proper form mustbe substituted for those shown in Fig. 5, and then the hoops run through the machine in the manner described. As the knives reduce the head-linings to definite form, irregular strips may be used to make uniformheadlinings. The form of the knives may be modifled to cut more pieces.

The machine, as illustrated in the drawings, is designed to operate upon strips which have been steamed and, are wide enough to form three strips of form suitable for head-linings; but cuttingknives adapted to cut more or less strips may be used, and its proportions and the form of the knives may be changed to adapt it for cutting or dressing strips for making hoops. The strips to be reduced are fed by hand under the roll E, and its rotation, together with roll E, carries the strip forward toward the cutter. The corrugated upper roll vated above the surface of the table to give a firm bearing to the strips as they are reduced by the cutter, the latter acting in conjunction with the recesses formed in the face of the block, to cut away all of the wood except those portions which form the head-linings or hoops. These are received upon the portion of the table which lies beyond the cutters, and which is raised above the plane of that part of the table which carries the strip as it is passed toward the cutter, and they are then passed between the rolls E and E, the upper one being corrugated to complete the crimping and give to the strips a permanent concave form on the crimped face. These curved strips are then formed into bundles and out intoproper lengths, as set forth in Letters Patent heretofore taken out by me.

WVhat I claim as my invention, and to secure by Letters Patent, is

1. In a machine for forming head-linings, 8220., from a strip of wood at asingle operation, the combination of the cutterhead and cutters 0, formed substantially as set forth, anda table and adjustable bearing-block of Babbitt metal or its equivalent, arranged to operate in conjunction to entirely cut away the intermediate portion of the wood, substantially as set forth.

2. In combination with the ribbed cutters, a table of which the surface immediately nndesire der the cutters is adjustable, so that it may be raised above the plane of the table, and having that portion which receives the stuff to be cutlower than that portion which support-s the strips after they have been formed by cutting away the residue of the wood, substantially as set forth.

In testimony whereofI havehereunto set my hand in the presence of two attesting witnesses.

LOUIS REED.
