SETTING-UP AND FORMING MACHINE FOR BARRELS, 80C.

SPECIFICATION forming part of Letters Patent No. 479,627, dated July 26, 1892.

' Application filed October 29, 1891- Serial No. 410,206. (No model.)

T0 aZZ whom it may concern:

Be it known that I, HENRY CAMPBELL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Setting-Up or Forming Machines for Barrels, &c.; and I do declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to by the barrel-hoops without the intervention of any temporary head, former, or truss-hoops.

It is the object of my improvements to fa cilitate this operation and enable it to be performed in a more perfect manner by labor which is of a lower grade and less expensive than that which has heretofore generallybeen employed for the purpose.

My invention relates to those parts and combinations thereof hereinafter more particularly set forth and claimed.

In order to make my improvements more clearly understood, I have shown in the accompanying drawings means for carrylng them into practical effect without, however, limiting myself to the particular constructlon which, for the sake of illustration, I have de lineated.

In the drawings, Figure 1 is a vertical sectional view of a barrel-setting-up machine embodying my invention. Fig. 2 is a sectional view of the same on line A B, Fig. 1. Fig. 3 is a detail view of one of the points.

Referring to the drawings, 1 indicates a stand of any suitable character, on which s vertically adjustable a plate or table 2. This adjustment is preferably eifected by forming the stand with a tubular bearing 3, in which fits a post 4, fixed to the plate. The post is clamped at any desired height by means of a set-screw 5. The plate 2 is provided with concentric flanges 6 7 on its under surface, (or, if preferred, on its top surface,) in which are formed bearings 9 10. In these bearings are mounted shafts or pins 8, which extend in a direction which is radial or from the center toward the periphery of the table. The outer ends of said pins are armed with points 11, having screw-threaded stems 12, adapted to be fixed in the pins 8. The points 11 are preferably not conical, but have sharp edges running vertically and parallel with the grain of the staves, which latter are shown at as.

In setting up the barrel the barrel-head 00 I is first placed on the plate 2, where its parts are confined by a weight or other clamp 13. The crozed staves are then applied around the head and are lightly tapped against the points 11, which will cause the latter to separate and enter the grain of the Wood sufficiently to hold the staves in place. The hoops are then applied, uniting the staves to one another and to the head. The pinsS are then withdrawn and the barrel removed.

In putting the staves in place their'lower ends are stopped in proper position by aring 22, which is attached to the stand 1. For different sizes of barrels different rings may be employed. If a truck or other open-ended barrel or firkin, it will be complete. If it is to be closed at both ends, the other head is applied in any suitable manner.

For operating the pins 8 I prefer the following means: 14 indicates springs applied around the pins and bearing at their outer ends against the flange 6 or other suitable part or attachment of the table and at their inner ends against studs or collars 15, fixed on the pins 8. These springs normally tend to force the pins inward out of engagement with the staves.

16 is a cone or frustum thereof engaging the inner ends of the pins and mounted and adapted to move vertically in the post 4:. It

is actuated by a rod 17 and treadle-lever 18, fulcrumed at 19 on a link 20, suspended from the stand 1.

21 is a guide-collar for the rod 17.

Before the staves are applied the operator depresses the treadle 18 sufficiently to project the points 11 to a position in which they will engage the staves, as already described. The lever 18 and cone 16 will be held in this position by a ratchet 23, axed to the stand. WVhen the staves are hooped in place, the release of the lever from the ratchet will permit the springs 14 to retract the pins.

24 is a spring connected with the treadle,

or, if preferred, with the rod 17 for aiding this action of the springs 14.

In vertically adjusting the plate 2 to suit different lengths of barrels, kegs, 850., I prefer to employ a cam or eccentric 25, mounted on the sleeve 3 by a stud 26 and having a handle 27.

28 is a roller mounted on the post 4 by a stud 29 and engaged by said cam. The turning of this cam will move the said post and table 2 up or down until the desired height is reached, when the set-screw may be caused to rigidly secure the parts.

I will now describe an additional means for temporarily holding the staves against the head 00 and pins 8, which means may be used in connection with said pins or employed independently thereof. 30 is a movable fingersuch as a metallic spring--adapted to engage the outer side of a stave and to hold the same from outward movement. A series of such fingers is provided sufficientlyin number to hold the staves of which the barrel may be composed, the fingers being mounted on a suitable fixed support. I utilize the clamp-weight 13 for this purpose, providing it with bearings 31, in which are mounted on pivots 33 oscillatory arms 32. Said fingers are formed with shanks 34:, having slots 35, and the fingers are thereby and by bolts 36, passing through the slots, secured to said arms in such manner that the fingers may be radially adjusted according to the diameter of the barrel-head. On each arm 32 is formed or attached a swell or proj ection 37, situated a little nearer to the center of the machine than is the pivot 33 of the arm, but adapted to be by the upward movement of the arm thrown to a point farther than the pivot from said center. 38 is a spring bearing on the projection 37 and adapted by its pressure to hold the arm either down, as seen in full lines in Fig. 1, or up, as seen in dotted lines. As the staves are applied and tapped into place with their crozes engaging the edge of the head, the fingers 30 are brought down one after the other to engage and retain the stave. In order that the release of the barrel may be more readily effected, I provide for lifting all of the fingers simultaneously. To this end the weight 13 is furnished with a vertical guide or bearing 39, within which moves a slide 40, adapted to engage and depress the inner ends of the arms.

41 is a hand-lever pivoted in or on the guide 39 and connected with saidlslide for depressing it.

What I claim is 1. In a setting-up machine for barrels and similar articles, the combination of a stand,a support for the barrel-head carried thereby, and outwardly-directed radially-movable pins having points adapted to engage the staves, substantially as set forth.

2. The combination of the stand, means for supporting the barrel-head, radially-movable parts having outwardly-directed points for engaging the staves, and means for retracting said parts, substantially as set forth.

3. The combination of the table, the clamp 13 opposite the same and adapted to secure the barrel-head, pins 8 for engaging the staves, springs 14, connected with said pins, the cone 16, engaging the pins, and means for moving the latter, substantially as set forth.

4. The combination of a support for the head, radially-movable parts having points for engaging the staves, means for retracting said parts, and movable fingers adapted to hold the staves against the head and in engagement with said points, substantially as set forth.

5. The combination, with a support for the head, of upwardly and downwardly movable pivoted arms mounted thereon and fingers adapted to engage the outer faces of the staves and carried by and longitudinally adjustable on said arms, substantially as set forth.

6. The combination, with the weight or clamp 13, of the arms 32, pivotally mounted thereon, fingers 30, adjustable on said arms, and means for operating and holding the arms, substantially as set forth.

7. The combination, with the weight 13, of the arms 32, having projections 37, springs 38, engaging the latter, fingers 30, carried by the arms, and the slide for depressing the inner ends of the latter, substantially as set forth.

8. In a barrel-setting-up machine, the combination, with the stand, of pivoted and vertically-oscillatory fingers mounted above and adapted to pass down over and engage the outer sides of the upper ends of the staves,

means for individually supporting said fingers, and an actuating device or mechanism for simultaneously disengaging them from the staves, substantially as set forth.

9. The combination of a table, a clamp opposite to the same and adapted to secure the barrel-head, pins having outwardly-directed points radially movable and adapted to engage the inner faces of the staves, springs for moving said pins radially in one direction,

and means for moving and holding said pins against the action of the springs, substantially as set forth.

10. In a barrei-setting-up machine, the combination of means for holding the barrel-head, a series of pivoted and vertically-oscillatory arms adapted to come down toward the ends of the staves as the latter are put in place, and inwardly-operating spring-fingers carried by the arms, substantially as set forth.

11. In a barrel-setting-up machine, the com- 5 binationof a meansfor holdingthebarrel-head, a support for the lower ends of the staves, and upwardly and downwardly movable holders or fingers independent of each other, supported above the said head-holding means and adapted to be broughtdown over and I0 outside of the upper ends of the staves, substantially as set forth.

In testimony whereof I aifix my signature in presence of two witnesses.
