BARREL-HEADING MACHINE.

, Application filed August 3, 1927. Serial No. 210,355.

This invention relates to barrel heading machines of the type employing suction mea-ns for handling the heads.

rlhe main objects of this invention are kto provide improved means for maintaining the suction head of the machine in a substantially horizont al plane during its movement in picking up the barrel head and placing it in the end of the barrel being headed; to provide im noved means Vfor compressing the barrel staves during and subsequent to the heading operation; and to provide improved leverage means for forcing the barrel head into the barrel. f

An illustrative embodiment of the invention is shown in the accompanying drawings wherein Y Fig. 1 is a side elevation of the machine with the barrel ,being worked upon, and suction head when inserting a head therein, shown in dotted outline.

Fig. 2 is a front elevation of the machine.

Fig.` 3 is a top plan view of the same.

Fig. l is a sectional View taken on line l-l of Fig. 1.

Fi 5 is a sectional detail taken on the line 5 5 of Fig. '1.

In the present barrel heading machine which is the subg'ect matter of this application, the suction head is mounted sov as to be in a horizontal plane at all times. At the same time, it is shiftable vertically and swingable sidewise, the head maintaining its horizontal position, however, throughout such movement.

rlhe advantage of this construction is that the chime in the upstanding ends of the barrel staves forms an annular horizontally disposed groove for receiving the beveled edge of the barrel head, and when the suction head which carries Vthe barrel head is lowered into the upper end of the harrel being worked on, the barrel head will automatically be in correct angular position to fit into the chime without necessitating rocking or shifting of the suction head to bring it to a horizontal pla-ne. lilith thisl construction, considerable time is saved and, of course, that means a reduction in manufacturing cost.

ln the construction shown in the drawings, a suitable framework 1, rpreferably formed of angle irons. supports a vertically Vdisposed cylinder 2 which communicates at its upper and lower ends with suction pipes 3. and f1 respectively, which join a main suction pipe 5.

A sleeve 6 surrounds the cylinder 2 in spaced-relation thereto and is vertically slidable thereon. The medial portion of the cylinder 2 is provided with an aperture 10 vthrough the wall thereof for providing com- -ed shank 1G which embraces opposite sides of the duct 12 is pivoted thereto at 17 adjacent the lower end thereof. A prize bar 1S is slidably mounted between the side arms of an inverted U-shaped bracket 19 near one end thereof and the other end thereof is bifurcated to likewise embrace the duct 12, the bifurcated arms thereof being p`votally attached to the bifurcated arms 16 of the handle at the point 20. A coil tension spring 21 which has one end thereof attached to the bar 18 and the other end thereof to a clip 19 fastened to the head 14, is provided for normally holding the bar 18 in the position shown in 1 of the drawings. An inverted V- shaped bracket 22 is rigidly mounted on the framework 1 for receiving the outer tip end of the bar 18 when the bar is shifted endwise by movement of the handle 15 about its pivot 1T to a horizontal position. In this manner the bar 1S and the bracket 22 serve to bring the suction head and the barrel top held thereon into registration with the open end of the barrel. lllhen the handle 15 is rotated to the position shown in dotted lines in Fig, 1, the bar 18 is moved relative to the bracket 19 and into the guide bracket 22, and the handle is restrained from further rotation by the engagement of the right hand end portion of the bar 18 with the pivot pin 17 of the bifurcated shank 16. Vhen further pressure is applied on the handle, the suction head 14 together with the ducts 11 and 12 are moved downwardly for engaging the barrel head on the end of the barrel.

Means are provided for aiding and assistthe unit which comprises'the sleeve 6, duct 11, duct 12 andsuction head 14 carried thereybyaud comprise a pair of ropes or cables and each et whichV has one end attached to eye- bolts 27 and 2,8 respectively, which in v turnare secured to a plate 29 which forms the lower closure ot the sleeve r6. lThe opposite ends oi the cables 25 and 26 pass upvardly and over pulley wheelsV 33 and 34 respectively' and then downwardly within verticalk tubes 35 and 3.6 respectively, the lower ends of each being attached to counter- ,v'eights13?n which are slidably housed within the tubes and 36. A similar plate 30 forms closure for the upperend of the sleeve 6 and both closures are provided with openings therethrough for receiving the vertical-ly disposed rods' 31 and 32 which provide guideways'i-or the' unit.

lvleans are provided for drawing together the upstanding ends ont the staves of the barrel being headed'and comprise` a iieXible cable '40 having its ends anchored at 41 .to the yiirznnework and thev medial vportion thereoi formed in a loopwhich is adapted to be placed around the upper ends ofthe barrel staves.

Thetwo sides of the looped cable 40 pass' through the medial portion of a member 42 which carries a pair of pulley Wheels 43 and 44 pivotally mount The member 42 is horizontally slidable on the framework V1 toward and taway from the barrel 'being worked upon and movement thereofis controlled by a toot lever 46 pivoted at oneend 47 yto the supporting frame 1 and provided with a coil tension spring 48 which bears between the trameand the lever for normally holding it in a substantially horizontal position. Lever 46 has a vertically disposed link 49 pivotally attached thereto, vthe upper end of which is pivotally connested 'at 50 to one end of each of links 51 and 52.V The opposite end of 4link 51 is pivoted at v53 to the 'framework 1 and these links, when in operative position are in the form oi an inverted V as shown in Fig. 1 of the drawings. Link 52 has its other end connected to the member 42 so as to shift the same horizontally toward the barrel being worked upon when the i'oot lever 46 is depressed. The outer or bearing :tace or' lmember 42 is arcuate so as toiconiiorm to the outer periphery of a `barrel being headed as shown particularly in Figs. 3 and 4 of the drawingsl The frameworkl is formed so as to provide'a table 60 'for supporting a pile of barrel heads 61 preparatory to their being placed in the barrels being headed. An upstanding semi-'circular guide retaining member 63 is provided on lthe tab-le 6,0 for keeping the supply of Vbarrel headsv in'position thereon; l In the operation of this machine, a stack of barrel heads is piled on the table 6() and ed thereon for bearing against the cable 40.

the suction fan (not shown) which is connected to the duct 5, is started. Thiscauses they air to be drawn in through thefsuct-ion head 14 which, with ducts 12, 11 and sleeve 6 operate asa unit. A Vbarrel is placed in position and the cable 40 placed therearound, and partially drawn tight by depressing the foot lever. `The' suction headunit is then swuno' over to the supply of barrel heads and lowered down against the top head. The suction lifts this barrel head fromA trie pile whenthe head is raised and it is then swung vabout a vertical lairis until it is directly above the barrel being headed, at which time the handle 15 is pulled downwardly-into a sul stantially horizontal position; This movenient of the vhandle 15 causes the prize bar 18 to move endwise so as to pass betweenV the upstanding sides of the inverted, Yfl-shaped bracket 22. Further downward movement ot the handle 15 causes the 'bar 18 to bear against the top end oi the bracket22 and thus center the suction head over the barrel as it moves downwardly to bring the barrel head which is being carried thereby into the chime of the barrel being headed.' The foot lever 46 is then further depressed, thus securely clamping the head in the barrel. The suction head is next lifted upwardly, thus breaking the suction and' releasing the barrel head.

.A suit-able hoop is then placed around the top of thebarrel andthe foot lever 46 .re-

leased, thus taking the tension oli o .the cable 40, thereby releasing the barrel. Raising and lowering out the suctionhead unit is rendered comparatively easy by reason ofthe counterweights 37 which are so proportioned .as to permit ready raising and lowering of the suction head unit. l l

Although but onespecic embodiment of vthis invent-ion has been herein shown and described, it is to be understood that numerous details of the construction shown may be altered or omitted without departing from the spirit` of this invention as defined .by the following claims. i
