BARREL-HEADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 437,785, dated October 7, 1890.

Application tiled June 2,1890. Serial Nol 353,963. (No model.)

tute a compressor which encircles the part of the barrel or Cask to be headed, and while so encircling said part are held in such position by suitable mechanism, said parts being then forced or pulled downward, said movement forcing said bearing-pieces comprising the compressor to hug and impinge against all the staves of the barrel or cask, consequently bringing said staves inward and together (to form an unbroken periphery) and around the head, which is suitably held by the operator, the head being forced into the croze in the staves ready to lhave the hoop placed thereon. Said parts may then be released. Any form of mechanism may be cmployed to operate these bearing-pieces forming the compressor and the mechanism which holds them in position when encircling the barrel and when they are forced downward. In the present instance I have shown and described them as attached to one form of mechanism, which is preferably placed below the floor of the shop.

In the accompanying drawings, forming part of this specification, Figure lis a sectional view taken at the line l l of Fig. 2, the upright arms being, however, shown, as well as a side view of my improvements, a barrel being shown in the machine. Fig. 2 is a top view of one form of mechanism for operating the machine, the upright arms being omitted and the iioor being removed. Fig. 3 is a perspectivc view of one of the bearing-pieces- Fig. 4 is a view in elevation of my improved devices around a barrel, being partly broken away at the top on one side to show the bar rel-head, which is in section, one of the bearn ing-pieces, and thc encircling-ring, which are also in section. Fig. 5 is a view in elevation of my improved devices around a barrel as they appear when the head has been forced into the barrel, the parts being partly broken away at the top on one side to show the barrel-head forced into position. Fig. 6 is a top view of my improved devices shown in Fig. 5. Fig. 7 is a top view of a plate and disk and the mechanism which forces all the upright arms carrying the bearing-pieces inward or outward simultaneously. Fig. 8 is a view of a modification of my device, rollers being shown to take the place of the bearingpieces. Fig. 9 is a view of modilied mechanism for keeping the bearingpieces in position against the barrel when the staves are being forced together.

I will rst describe my improved devices and then one Jform of mechanism for operating the same. Y

In the drawings, A represents the barrels.

B represents the upright arms of the machine, the upper parts of which I peculiarly construct. To the upper parts of these arms I attach in any suitable manner the bearingpieces C. I preferably connect them by a fcrew-and-bolt connection. They may be welded on the arms, if desired. I may use as many of the arms with bearing-pieces attached as I desire, in the present instance six being shown. These bearing-pieces are so shaped that when placed around the periphery of the barrel they form, practically, a solid wall, constituting a compressor around said barrel, as shown in Fig. (i. The lower half of these bearingpieces O is cut away or flared outward, so that when they are moving downward with the arms they gradually impinge against the staves and bring them all together, as some of the staves dare outward more than others. These bearing-pieces are also beveled at their upper inner edge, so that the hoop can be placed on the barrel more readily. These bearing-pieces may b e made of any size and of any other form and shape than the ones herein shown.

The arms B at their upper extremitygwhere the bearing-pieces are attached, are of apeculiar construction, being of spear-head shape IOO D and having a shoulder or offset E. The

upper part of these arms B may,- h0wever,be.

dierently shaped. They are so shaped to enable the ring to more readily slip down over them.

F represents a ring, which is suitablyT hinged on vone of the arms B, as shown in Fig. l. It may be otherwise connected. This ring may be counterbalanced in any suitable manner. This ring slips over the arms B and lodges in the offsetE in said arms to hold said arms and bearing-pieces together, as shown in Figs. 4:, 5, and 6. The ring is held in this position by a locking device Gr. The ring slips down ever these top parts of the arms B easily on account of the peculiar construction of the top portionv of the arms at D. The ring may be operated in any other manner. pieces and arms may also be held together or against the barrel in any other suitable manner.

When kthe barrel has been placed in proper position, and the arms carrying the bearingpieces have been brought together and the ring'hasbeen placed around them, all that is necessary is to hold the head in the barrel opposite the croze in the staves and operate Athe machine downward. This downward movement carries the arms, bearingpieces, and'ringdownward, forcing the chucks against the staves of the barrel, the lower the parts descend the tighter they impinge, as the bilge of the barrel becomes more marked. Consequently the staves are forced inward and togeth'er, .and the head into the croze in the staves. The hoop may then be'placed on the barrel. The ring is then unlocked and it is pulled upward, being counterbalanced. The arms `B can then be raised and forced outward, so that the barrel can be taken out to be headed at its opposite end.

In order to place the barrel in and out, one of the arms can be moved backward farther than the other arms on account of the slot H (see Fig. 6) being elongated, the other arms passing through similar but shorter slots.

I shall now describe the mechanism for bringing the arms B up and down and inward and .outwar 1. This mechanism may be changed, if desired. I

K represents the floor of the shop, through which pass the arms B, slots being provided for that purpose. The lower ends'of the arms B are connected to a plate L in any suitable manner. This plate has three arms M, which have sleeves, as N, which slide up and down on `the uprights or standards O, which standards are attached at the top and bottom to plates P P. (See Figs. 1 and 2.) A screw-shaft R extends between the plates P P and is suitably journaled in boxes S. This screwthreaded shaft passes through the plate L, (through a screw-threaded opening therein.) On said shaft R is connected the gear-wheel T. On ashaft V are connected two frictiondisks Wand a pulley X. This shaft is journaled in boxes Y, a lever Z being attached to The bearing-- the shaft V at one end to throw said disksW in and out of contact with the friction-disk A', which is connected to one end of a shaft B'. (See Fig. 2.) This shaft B' is journaled in the boxes O', and carries at its inner end the pinion-wheel D', which meshes with the gear-wheel T on shaft R. These parts operate as follows: A belt passes over the pulley X,imparting motion t-o it and to the shaft V, -the friction-disks W W revolving therewith, and said shaft V, being loosely journaled in the boXes Y Y, can be moved forward and backward, thus throwing one of the disksW in contact with the disk A' and one out of Contact therewith. Motion being thus imparted to the disk A', the shaft B', on which it is connected, also revolves. consequently imparting motion to the pinion wheel D', which is also on said shaft B', and said wheel D', meshing with -the gear-wheel T, imparts motion to it, said gear-wheel T in turn revolving the screw-threaded shaft R, on which it is keyed. This shaft R, working in the screwthreaded opening in plate L, moves said plate up or down at the will of the operator, throwing one or vthe other of said disks lV in contact with disk A', and the arms B, being attached to the plate, move up or down with it. The arms B may be thrown in or out simultaneously. This is accomplished'as follows:

E' represents a disk pivoted on the top plate P. To this disk are pivotally attached one end of the arms or straps G'. The other ends of these arms are slotted, and the arms B pass through this slotted portion.

E' as to be on a line out of the center of the pivotal point of said disk E', so that when one arm B is pushed inward it revolves the disk E' to the left, consequently pulling the other arms B inward, as they are all similarlyconnected to the disk E', and by pulling one of the arms B outward revolves said disk VE' iu an opposite direction, and all the arms are forced outward.

The barrel is headed as follows: When the arms are in the position shown in Fig. 1,'one of them (the one in the elongated slot H, as seen in Fig. 6) is thrown down and the barrel A placed on the platform K', the top truss-hoop having been removed from the barrel. The arm B in slot I-I is then again thrown back and all the arms are consequently throwninward, as shown in Fig. 4, so that the ring can be pulled down by the operator and placed in the osets F., which is now done. The machine has now assumed the shape shown in said Fig. 4. The operator then t-akes'a punch and forces it into the head of the bar- :rel and places it into the barrel oppositethe croze cut in the staves, as shown in Fig. 4. Vith his other hand he moves the lever Z in the proper direction, so that the arms will vbe forced to move downward. This downward movement is continued until the parts assume the shape shown in Fig. 5, where it will be seen that the head has been forced into Y Y j Y These Y straps or arms G' are so pivoted to the disk IOO the croze in the staves. It will also be seen that the arms, bearing-pieces, and ring have moved downward far enough to allow of a hoop being placed on the barrel. (See Fig. When said hoop has been placed thereon, the ring F is released and it assumes its former position. (See Fig. l.) The lever Z is reversed, the arms B, carrying the bearingpieces, move upward, and the barrel can be removed. In the downward movement, just above described, the bearing-pieces O impinge against the barrel to force the staves inward and together, they being retained in position by the ring F. As they move downward, the pressure against the barrel is great-er as the barrel widens, (the bilge becoming greater.) This downward movement is continued until the head is in, when it is stopped, the hoop being then put on.

The ring F could be omitted and other mechanism used to keep the bearing-pieces in position. One form is shown in the modifications in Fig. 9, where the arms are forced to travel against rollers M in brackets N', rigidly secured to the floor or platform. The arms would in this case be of a peculiar construction, as shown, having a greater degree of curvature, so that when they were moving downward they would also be forced inward and against the barrel, consequently allowing the bearing-pieces to force the staves inward and together.

It is obvious that other mechanism could be employed, and other mechanism might be directly connected to the bearingpieces to keep them in position.

The main feature of my invention consists in providing a series of bearing-pieces to form a solid wall around the barrel when brought together, only small spaces being left between the chucks when desired, and holding said bearing-pieces in that position as they move downward over the periphery of the barrel. I preferably employ the mechanism as idescribed; but I may use only one or more of said parts of my invention, and may use them in connection with barrel-heading machines of a form other than the one herein described.

What I claim as new and of my invention, and desire to secure by Letters Patent, is

1. In a barrel-heading machine, a series of bearing-pieces mounted upon pivoted arms and constituting a compressor, means for bringing the bearing-pieces inward to encircle and bear against all the staves of the barrel at its periphery, and devices for holding said bearing-pieces rigidly in posit-ion against the staves while moving downward, in combination with mechanism for moving the compressor downward, substantially as described. 2. In a barrel-heading machine, a series of bearing-pieces constituting a compressor and pivoted arms supporting the bearing-pieces, in combination with a ring encircling the bearing-pieces and holding them in position around the periphery of the barrel and operating mechanism for moving said compressor downward, substantially as described.

3. In a barrel-heading machine, a series of independently-mounted bearing-pieces constituting a compressor, the said bearing-pieces having concave inner surfaces, and a ring encircling the bearing-pieces and holding them against the periphery of the barrel, in combination with operating mechanism for moving the compressor upward and downward, substantially as described.

4. In a barrel-heading machine, a series of bearing-pieces supported on arms having a spear-shaped head and an offset E, in combination with a ring, as F, substantially as set forth.

5. In a barrehheading machine, a series of bearing-pieces mounted on arms, as B, in combination with a counter-balance, and a ring, as F,'hinged t0 one of said arms,substantially as set forth.
