BARREL-TRIMMING MAcHlNE.

SPECIFICA'I'ION forming part of Letters Patent No. 341,581, dated May 11,1886.

Application filed April 24, 1885.

To all whom it may concern:

Be it known that I, ADoLPH KIRCHNER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Barrel-Trimmng Machines, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure lis a top view of a barrel-trimming machine embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a section in the plane of the line :v w of Fig. 1, viewed in the directionindicated by the arrow 1 there shown. Fig. 4 is a section in the plane of the line 3/ y of Fig. 1, viewed in the direction indicated by the arrow 2 there shown. Fig. 5 is a detail, the same being a side view of the sliding box or bearing; and Fig. 6 is a detail, the same being an end view of the parts shown in Fig. 5. I

Like letters of reference indicate like parts.

The meeting edges of the staves of barrels are not always even,and thus makea rough or irregular surface. This nnevenness has heretofore been remedied by trimming down the projecting edges by means of hand-tools, so as tov make the outer surface of the barrel present a neat and finished appearance.

The purpose of my invcntion is to attain the same result expeditiously by means of an organized machine. The manner in which I accomplish this will hereinafter be fully explained.

A represents the frame of the machine.

B is an unfinished or untrimmed barrel.

O is a clamping` plate or disk, rigidly attached to one end of an axle or shaft, 0/.

D is a box or bearing in which the axle or shaft O' turns.

E is a collar upon one side of the box D, and F is a collar on the other side thereof. These collars prevent this axle or shaft from moving laterally or endwise in its bearings.

G is a clamping` plate or disk rgidly attached to one end of an aXle or shaft, G', turning in the boxes or bearings D' D'. The shaft or axle G' is laterally yielding or capable of moving endwise, but its movement in one direction is limited by means of a pin or stop, H, passing through the said shaft. This stop I would regard as equivalent to a fixed collar.

serial NO 183,482. (NO mmm.)

I is a laterally-movable collar on the shaft G', and .I is an open spiral springsurrounding the said shaft, and bearing on one end on collar I and at the other against the outer bearing', D'.

K is a treadle, and K' is a cord or rope passing through fixed eyes a (l, and connected both to the said treadle and to the collar I. This treadle, as indicated in Fig. 2, rests upon a spring, a'.

The clamps or plates C' and G are fianged, as is clearlyindicated at b b, Fig. 2, to slightly overlap the ends of the barrel.

To arrange the barrel in place, I depress the treadle K, thus, through the instrumentality of the rope K' and collar I, compressing the spring J. By this means the clamp G may be pushed or moved laterally away from the clamp O, and it will remain where placed as long' as the treadle is depressed. I then raise the barrel and place one end thereof in the clamp C. Then, by releasing the treadle K, the clamp G will move toward the other end of the barrel and clamp it, that end being held in proper position to admit of that result. It will be perceived that the barrel-clanlps are thus adjustable to barrels varying,` somewhat from each other in height or length, and also that sufficient space or room may bemade between the barrel-clanips to permit the barrel to be placed with facility between the clamps.

To prepare the barrel to be arranged temporarily in the clamps, I apply upon its ends hoops c c, which may be temporary or not, as may be desirable or expedient.

L is a drum or cylinder, mounted rigidly upon a shaft, L'. In length this drum is solne- What shorter than the barrel to be trimmed, and its face or perimeter is Curved iuwardly, as shown, to correspond to the outward curvature or bulge of the barrel.

To the perimeter of the drum or cylinder L I apply, by means of some glutinons substance, small pieces or particles of broken or pnlverized glass, or fine sand or emery, or other well-known finishing or polishing substance or material.

M M are boXes or bearings, in which the shaft I/ turns or bears.

mo These boxes MM, I ar-range in outer or supplemental boxes,N N,

and secure the formcr in the latter by means of set-screws O O.

P P are plates, on which the boXes N N rest, and these plates and boxes N N are connected by means of dovetail joints, asindicated at d, Fig'. l, so as to permit the boXes N N, (which bear the boxes M M and axle 11,) to be capable of sliding` in the plates P P. Any other form or joint or connection or way, however, which will permit of this sliding' movement may be employed instead of dovetail joint.

Qis a forked or bifurcated arm, in the forkcd ends of which the shaft L' turns.

R is a lever pivoted to the frame and to the single arm or branch of the arm Q.

S is a curved serrated plate attaehed to the frame.

T is a lever pivoted to the frame, and provided with a sliding,` catch, e, in connection with a small lever, e', pivoted to the lever T.

U is a connecting` rod or arm connecting the levers R and T.

N' N/ are Springs bcaring` against the boxes N N.

V is a driving-shaft, and A' is a belt-wheel mounted rigdly thereon.

B' is a spur-wheel mounted rigidly on the shaft NV, and D is a spur-wheel mounted rigidly-on the shaft L'. These spur-wheels engage each other, and their spurs or cogs are sufficiently long` to permit the barrel or cylinder L to be moved back and forth to a limited extent in the direction of the barrel B without causing a disengagement of these wheels, as is indicated in Fig. 2. E' is a spur-wheel, also mounted rigidly on the shaft W`, and E is a spurwheel mounted on the axle F and engaging the wheel E'. By these means the drum Or cylinder L will yield to uneven surfaces and to barrels varying' somewhat in diameter; also, the cylinder or drum L may be drawn away from the barrel by means of the leverT and the parts connecting` it with the shalt of the said drum, so that the barrel may be released with facility when finished. To permit this yielding movement of the drum L while the work is being` done, the catch e should be held out of engagement with the the plate S.

To remove the barrel, I depress the treadle K, as before, after having movcd the cylinder L away from the barrel. The clamp G is now loose and may be moved laterally away from one end of the barrel, thus permitting the barrel to be taken from the elamps. I now finish hooping` the barrel, or, if need be, remove the hoops c c and place other hoops thereon in place thereof suffieiently broad to cover any untrimmed or unfinished part which may exist near the said hoops.

It will be perceived that the portions of the barrel and those portions of the drum or cylinder L which meet each other while both are rotated movein opposite directions, and hence that a great degree'of speed and friction will be produced. The drum or cylinder L will trim the barrel, and the work will be done speedily and give the barrel a uniformly neat appearance.

I do not here intend to confine myself to all of the details of construction which I have shownV and described, as it is obvious that many details of construction may be Varied without a departure from the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A barrel trimming` or finishing machine in which are combined, substantially as specified, a rotative laterally-yielding` holder or clainp and a rotative trimmer or finisher.

2. A barrel trimming or finishing machine in which rotative barrel-holders are combined with a yielding rotative trimmer or finisher, substantially as and for the purposes specified.

3. The combination, in a barrel trimming or finishing machine, of the rotative trimmer or finisher L, mounted in sliding` and yielding bearings, and an adjusting-lever in operatve connection with the said trimmer, substantially as and for the purposes specified.

4. The combination, in a barrel trimming or finishing' machine, of a rotative trimmer or finisher mounted in sliding' boxes or bearings, the bifurcated or forked arm Q, the lever R, the connecting-rod U, the lever T, having,` thereon a catch, c, and the serrated plate S, substantiall y as and for the purposes speeified.

5. The combination, in a barrel trimming` or finishing` machine, of a yielding elamp for holdi n g the barrel and a yielding drum or cylinder having adhesively attached to its face or perimeter pulverized glass orlike attritive snbstance, and suitable mechanism for operati ng or revolving` the said clamps and drum or cylinder, as described.

In testimony that I clai m the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

ADOLPH KIRCHNER.
