Application filed March 3, 1906- Serial No. 304016.

To all whom it may concern.-

Be it known that we, MATHIAS F. QUEsT and MAX F. REIoH, citizens of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Barrel-Forming Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention has relation to improvements in barrel-forming machines; and it consists in the novel construction and arrangement of partsmore fully set forth in the specification, and pointed out in the claims. a In the drawings, Figure 1 is a top plan of the invention, showing its application to a complement of staves in the process of forming a barrel. Fig. 2 is a combined side elevation and section on the broken line 2 2 of Fig. 1, with the heads, however, advanced sufficiently to form the barrel. Fig. 3 is a transverse vertical section on line 3 3 of Fig. 2. Fig. 4 is an enlarged horizontal section on line 4 4 of Fig. 2. Fig. 5 is a vertical sec tion on line 5 5 of Fig. 4. Fig. 6 is a longitudinal section of one of the barrel-forming heads on the line 6 6 of Fig. 7, showing the stave-guiding wedges projected into the head. Fig. 7 is a transverse section on line 7 7 of Fig. 6. Fig. 8 is a face view of a portion of the adjusting-band for the wedges turned sufliciently to retract the wedges from the path of the staves. Fig. 9 is a section on line 9 9 of Fig. 8, and Fig. 10 is a perspective view of the temporary clamp for the staves.

The object of our invention is to construct a machine which will bend the complement of staves which constitute a barrel, at the same time leveling and trussing the barrel, the necessity of first bending one stave at a time being entirely dispensed with.

A further ob 'ect is to construct a machine which will be simple, readily manipulated, one containing a minimum number of parts, one operating on variable thicknesses and dimensions of stock, and one possessing further and other advantages better apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, 1 represents a suitable oblong frame along the bottom and adjacent to one side of which is disposed. a longitudinal drive-shaft 2, having terminal pinions 3. Each pinion meshes with'a gearwheel 4, forming an integral part of a nut 5, mounted on the frame and freely rotatable about a screw-threaded stem 6, whose inner end is keyed or otherwise secured to a conical head 7, the screw-threads of the stems 6 6 being, respectively, right and left hand, whereby the stems and heads carried by them may reciprocate simultaneously in opposite directions, as more fully hereinafter apparent, the heads being provided with guide ribs 7 traveling in suitable grooves or ways formed in the frame. The shaft 2 has keyed thereto at one end a clutch member 8, having conical engaging surfaces on each side of the center thereof, these surfaces being made to alternately and frictionally engage the conical surfaces of the depressions 9, formed in the pulleys 10 10, freely sliding over the shaft, the said pulleys constituting the female members of a clutch, of which the part 8 is the male member. From the pulleys 10 10 lead the open and cross belts 11 12, respectively, whereby upon the engagement of one pulley or the other with the member 8 rotation is imparted to the shaft 2, first in one direction and then the other, an intermediate or central position corresponding to a disengaged position for both pulleys, the belts leading to any suitable source of power or line-shaft. (Not shown.)

The mechanism for shifting the pulleys may be of any prevailing construction, that here shown being as follows: Each pulley has an outer hub portion 1 3, which is encompassed by the intermediate looped portion 14 of a 'horizontally-oscillating arm 14 pivotally secured at one end to a bracket 15 of the frame, the outer slotted ends of the arms being coupled to a link 16, whose terminal slotted ends play over the pins 17 at the ends of the brackets or arms 18, projecting from the frame. By seizing the terminal knob or pin 19 of the link and shifting the latter first in one direction and then the other one or the other of the rotatable pulleys may be brought into frictional engagement with the member 8 of the drive-shaft, and since the pulleys are constantly revolving in opposite directions by reason of the open and cross belts 11 12 thereof leading to a common line-shaft it follows that the drive-shaft 2 will be first rotated in one direction and then the other, de-

pending on Which pulley is in engagement with the member8. .Anintermediate position of the link 16 OfCO111S8:W1ll disengage both pulleys from the member 8.

Formed in the upper peripheral wall of 5 each head 7 are a series of transverse semi-annular openings 20, through which may be dropped into the head the barrel-hoop h, one

edge of each hoop resting against a circular shoulder 21, formed on the inner surface of the head, the opposite edge of the hoop resting against the bases, of a series of curved "'fwedge-shaped segments 22, whose inclined paces, as presently to be seen, collectively orm a guiding surface or wedge for ends of '5 the staves as the latter are being forced toj ward the closed bottoms of the conical heads *7. Each segment 22 is provided with a stem -'-'3, rejecting loosely through the wall of the ea 7, the stem having a terminal head 24 zoflcfonnected to the body of the stem by a neck ,225. These necks pass through elongated slots 26 of the transverse bands 27, loosely encompassing the heads 7 adjacent the open- "Wihgs 20. The slots 26 are disposed in the m? cam formations 28 of the bands, each cam 28 *ljaving a terminal shoulder 29 to limit the roation of the band in one direction. A knob 'or handle 30 is provided for each band. With the exception of the cam portions 28 the i bodiesof the bands 27 hug the peripheral 'ifl s' urface of the head, so that if the bands be $1? "'i g'iven a turn in proper direction, Fig. 7, to l-withdraw the earns 28 from under the heads $24 of the segment-stems 22 the several stems fwill be forced inwardly, and hence the sev- F eral segments will be projected inwardly to bear against the adjacent edge of the hoop h.

*By giving the band 27 a turn in proper direc- ,tion, Figs. 8 9, to bring the earns 28 under the 48 heads 24 the several segments will be retractedor drawn outwardly into the annular recess 81, formed for their reception on the in- ?"Tfier wall of the head. In their retracted position the segments will be virtually flush fi-tivith the inner wall of the head. The com plement of staves S is first assembled and R temporarily held in a clamp or strap 32, passed centrally about the body of the staves and the whole is placed on a curved support 5 or saddle 33 at the top of a centrally-disposed s tandard 34, bolted to the floor.

W The operation may best be described by 5 a reference to Figs. 1, 2, and 6. The comple- "Ument of staves held in the form of a cylinder 5flby the clamp 32 is placed on the support 33 flfbetween the heads 7 7, Fig. 1. The operator '*then drops the proper size hoopsh into the -''several openings 20, the hoops lodging against the circular shoulders 21. Then the bands 06927 are given a turn to project the several segments 22 into the heads and opposite the ad t *jhoent edges of the hoops previously introjduced. The operator then by proper shifting of the pulleys imparts rotation in proper 6% direction to the drive-shaft 2, which simulta- ,tation of the gears 4 4 imparts the necessarily reciprocating movement to the *stems 6 and heads 7, carried by them, so that the heads will now simultaneously move toward each other. As the heads thus approach they gradually encompass the staves, causing the latter to gradually conform to the conical contour of theheads until the staves are fully bent, Fig. 2, the ends of the staves with the bending operation being contracted to progressively narrower limits as they approach the bases or the narrow portions of the heads. As the heads thus pass over the staves the hoops h are driven over the gradually-converging ends of the staves and forced over the resulting barrel, the ends of the staves first passing over the inclined faces of the body of segments 22, said inclined faces safely guiding the staves into the hoops and preventing the jamming of the ends of the staves against the edges of the hoops, a result which would be inevitable with thick hoops. For very thin hoops the wedges 22 need not be brought into requisition, Fig. 9, and the same maybe retracted into their recesses 31, as a thin hoop will pass over the staves without any danger of amming or cutting the ends of the staves. When the heads are driven inwardly their full limit, they will come in contact with the ends of the staves, and thus automatically level the barrel previously bent and trussed. When the operation is complete, the machinery is reversed and the heads will travel away from each other, thus releasing the finished barrel. The latter is then ready for the crozing operation and for the receptionof the heads.

Having described our invention, what we claim is 1. In a barrel-forming machine, ahollow head of a contour conforming substantially to one end of a barrel and having a series of transverse semicircular openings formed along its peripheral walls for the reception of a corresponding series of hoops, substantially as set forth.

2. In a barrel-forming machine, a hollow head contoured interiorly to conform to one end of a barrel, and having a series of transverse semicircular openings formed along its peripheral walls for the reception of a corresponding series of hoops, and formations on the interior of the heads for guiding a complement of barrel-staves along thewalls of the head and past the hoops, substantially as set forth.

3. In abarrel-forming machine, a hollow head contoured interiorly to conform to one end of a barrel and having a series of transverse semicircular openings formed along the peripheral walls for the reception of a corresponding series of hoops, and a series of wedge-shaped segments carried by the walls of the head and distributed adjacent to the hoops, and collectively forming an annular guide for the staves in their passage into and through the hoops, and means for retracting the segments out of the path of the staves, substantially as set forth.

4. In a barrel-forming machine, a hollow head contoured interiorly to conform to one end of a barrel and having a series of transverse semicircular openings formed along its peripheral walls for the reception of a corresponding series of hoops, a series of Wedges aped segments distributed adjacent to the hoops, stems carried by the segments and passed loosely through the walls of the head, terminal heads on the stems, and rotatable bands encompassing the head, the bands having a series of slotted cam formations, and necks connecting the stems to the terminal heads loosely passed through the slots of said cams, whereby upon rotation of the bands in proper direction, the segments may be collectively forced inwardly beyond the walls of the head or retracted into suitable recesses formed for their reception, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
