GEORGE E. SMITH, OF MIDDLEPORT, NEW YoRit;

BARREL-FINISHING MACHINE;

SPECIFICATION forming part of Letters Patent No. 683,578,

dated October 1, 1901.

Application filed February 16, Serial No. 47,587. (No model.)

To all whom it may concern:

Be it known that I, GEORGE E. SMITH, of Middleport, in the county of Niagara, State of New York, have invented certain new and useful Improvements in Barrel-Finishing Machines, of which the following is a complete specification, reference being had to.the accompanying drawings.

The object of my invention is to produce an improved machine for leveling or trimming the ends of barrels, beveling, and crozing the same whichis simple and practicable in construction and which can be conveniently manipulated, if desired, by a single operator.

In the accompanying drawings, Figure I is a perspective view of my machine complete,

showing a barrel in place and the parts of themechanism in position for operation. Fig. II is a top plan view of the subject-matter of Fig. I. Fig. III is a diametrical sectional view of a barrel-rotating member and its case. Fig. IV is a side elevation of the cutter-head of my machine. Fig. V is an inner side elevation of the croze-housing detached. Fig. VI is a detail view showing means of applying the barrel-extracting member to the hoop of a barrel.

Referring to the numerals on the drawings, 1 indicates side pieces, and 2 cross-pieces, which constitute a preferred form of bedplate for my machine. They may be made of heavy timber or other suitable material and of any preferred dimensions.

3 indicates bifurcated stud-supports, of which two are employed, one upon each of the side pieces, and of which one is clearly shown in Fig. I of the drawings. These serve rigidly to support the case for the barrel-rotating member 4, (clearly shown in Fig. III of the drawings,) the case being preferably split and composed of two corresponding lateral sections 5 and 6,which are respectively provided at intervals with lugs 7 for the accommodation of bolts 8. Two of the bolts 8 serve also to secure the case to the studs 3. The barrel-rotating member preferably consists of a medial annular portion,t0 which the numeral 4 in Fig. III of the drawings is applied. It is preferably tapered to conform to the shape of a barrel end and should be of suflicient width to afford a firm bearing for a barrel when inserted. and forced endwise into it. The body part of the rotating member 4 is provided with a preferably medial annular flang'e 10, which works snugly between the side walls of its case. Upon opposite sides of its flange 10 and the opposing inner faces of the walls of the case, respectively, I provide corresponding registering annular grooves When the parts are assembled, as shown in Fig. III, the respective grooves upon opposite sides of the flange 10 and the side walls of the case afford races for antifriction balls 12, that serve to support the member 4 rev olubly within its case and to facilitate its ro tation therein.

The outer periphery of the flange 10 is toothed and at one point,preferably on one side of the case, is exposed through an aperture in the case to engagement with a pinion 13, fixed to an arbor 14, carried in a tilting frame 15, mounted,as upon a pivot-pin 16,in an upright 17, projecting from one of the side pieces 1. To the arbor 14 is secured a fixed pulley 18, by means of which rotary movement may be imparted to it, as by the aid of a belt, and thence communicated through the pinion 13 to the toothed flange 10. The end of the frame 15 opposite to that which carries the arbor 14 is provided with a counterweight 20, by which or by equivalent means the frame is normally tilted to compel normal disengagement between the pinion 13 and the teeth of the flange 10.

21 indicates a lever having a fixed fulcrum in the side piece 1, which carries the upright 17 and which, crossing the bed-plate, terminates upon its opposite side in a treadle 22. The lever is operatively connected, as by a link 23, with the frame 14 in such manner as to enable an operator by pressure upon the treadle 22 to operatively connect the pinion 13 with the teeth of the flange 10.

24 indicates studs which may be similar to the studs 3 and which, as upon a pin 25, carry a tilting frame 26, having at its outer end a counterweight 27, corresponding with respect to the frame 26 in function to the counterweight 20 of the frame 15.

The frame 26 may be operated by any suitable system of levers; but I prefer to employ a suspended hand-lever 28, fulcrumed, as indicated at 29, from a suitably-suspended support and connected, as by a link 30, with the counterweighted frame 26.

Upon the end of the frame 26 opposite the counterweight 27 is revolubly mounted, as in boxes 32, an arbor 33, whose end extends within the body part of the barrel-rotating member 4. A pulley 34 is fixed to said arbor and affords means for rotating it, and that pulley preferably derives motion from the same lineshaft as that to which the pulley 17 is belted. To the end of the arbor next to the member 4 is secured a cutter-head. (Clearly shown in Figs. IV and V of the drawings.) Iprefer to employ a cutter-head which will perform all of the functions of finishing a barrel; but obviously it might be employed to perform any one of them separately. Accordingly I employ, by preference, upon the arbor 33 a saw 36, and next to that a bevel-saw 37, and last a series of crozes. The crozes preferably consist of V-shaped cutters 38, adj ustably mounted in grooves 39 in a croze-housing 40.

41 indicates a nut upon the threaded ex-' tremity of the arbor 33, by which the several cutters may be securely assembled upon the reduced end of the arbor. 42 indicates setscrews which, screwing through the housing 40 into the respective grooves 39, are adapted,

respectively, to fix the adjustment of the cutters 38.

Upon the side pieces 1 of the bed-plate I ing four posts 44, the two on each side being united by guide-rods 45.. Working between the posts upon the guide-rods is a sliding cross-piece 46 within a box 47', on which is longitudinally fixed, but revolubly movable, a shaft 48. To the end of the shaft 48 next the barrel-rotating member is secured a tailto fit the end of a barrel. It is coaxial with the member 4, so that a barrel mounted in it may be centered with certainty into the member 4 by pressure applied endwise upon the shaft 48. For applying such pressure I prefer to employ a hand-lever 51, secured, as by purpose of the lever being to afford means of imparting thrust motion to the shaft 48 without interfering with its rotation. The lower end of the lever 51 is adapted to set into a series of recesses 53, provided forit in abedplate extension 54. The recesses or boxes 53 are intended to afiord a graduated series of fulcrum-points for the reception of the lower end of the lever.

In practice a barrel being mounted in the seams curely set in place, so that after the lever 51 has performed its function of inserting the barrel it does not require to be held in posi-- tion during the cutting operation; The operator having set the barrel 55 in position may by operation of the treadle 22 and the handle 28 cause the cutter-head and the barrel to rotate in opposite directions, thereby neatly and expeditiously finishing the end of the barrel, imparting to it at one operation a level and a beveled end and asuitable croze.

I show in connection with the lever 51 a link 56, provided upon its free end with a hook 57, (see Fig. VL) which is adapted to engage a hoop 58 on the barrel and to extract it, when required, from the rotating member 4.

What I claim is 1. In a barrel-finishing machine, the 0mm bination with a split case, of a barrel-rotat ing member provided with an annular flange 1' working between the walls of the case, ball- I races in the flange and opposing walls of the I case, and antifriction-balls in said races.
