BOTTLE- -CAPPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 527,193, dated October 9, 1894.

i Application filed May 4, 1894. Serial No. 510,052. (No model.)

of Indiana, have invented certain new and useful Improvements in Bottle-Capping Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. i

My invention relates to improvements in bottle capping machines, and more particularly to amachine for applying a metallic cap provided with a depending flange tothehead of a bottle having an annular shoulder against the cap ispressed in locking contact. I

The primary object of the invention is to provide a simple, compact machine, adapted to be automatically operated from a single source of power.

Further objects of the invention are to provide effective means for keeping the bottle in properalignment when the same is forced upward in position to receive the cap; to provide automatic means forfeedingthe eaps,in con1.

bination with means for preventing the caps from crowding or interfering with the capfeeding mechanism; to provide means for holding the caps and head of the bottles in their proper relative positions for the compression of the caps so as to prevent the breaking of the bottles; and toprovide means for conveying away the liquid from the machine should a bottle break while compressing a cap around the head thereof.

With these several objects in view the invention consists in the features of construction and combinations of parts hereinafter fully described and pointed out in the appended claims.

In the accompanying drawings, forming a part of this specification, Figure l is a side elevation of a machine embodying my improvements, some of the parts being shown in section. Fig. 2 is a sectional plan view on the line lI-II of Fig. 1, illustrating the capfeeding mechanism. Fig.3 is a fragmentary vertical section on the line III-III of Fig. 2.

Fig. 4; is an inverted planof the bottle and l a bevel gear a cap aligning devices. Fig. 5 is a. plan view of the bottle holder with the liquid conveying trough arranged below said holder. Fig. 6 is a sectional View on the line VIVI of Fig. 1, illustrating the cam and means for placing the bottle holder in proper alignment. Fig. 7 is a perspective view of the cap feeding finger. Fig. 8 is an inverted plan view of the revolving feed table with the cam for releasing the bottle head and cap aligning devices. Fig. 9 is an elevation of the cap releasing and aligning plunger removed from the machine. Fig. 10 is a slightly modified form of bottle holder. Fig. 11 is a view illustrating the action of the aligning jaws on the bottle head and Fig. 12 is a fragmentary vertical sectional view illustrating the cap compressing mechanism and means for operating the same.

In the drawings A indicates the hollow with a flared base. The standard has formed thereon bearings ct and a in which is journaled a drive or main shaft 61. having on one end thereof a fast pulley a an idler a and a gear wheel a and on the other end of said shaft a slotted wheel a loosely mounted on the shaft and having secured thereto or formed integrally therewith a sleeve of and g The bevel gear a? is in mesh with the bevel gear b of the vertical shaft or spindle b; the said spindle being journaled in bearingsb of the bracket b, which bearing is secured to the standard, A. Upon the upper end of the spindle b is adj ustably held a bottle holding frame B; said frame having set screw, or other means, and is further provided with a spline for preventing saidholder from any movement except with the spindle. The apertures b of the bottle holder are adapted to register with a spring-pressed vertically movable plunger b arranged in the bracket b the upper end of said plunger having a head or collar o preferably some- 5 what larger than the diameter of the bottle 1o tacle into which any liquid would be deflected by the shield u should a bottle break while in the frame B, thus preventing the liquidfrom passing intethebracketb around the bottle raising mechanism. The plunger b has a friction roller b at its lower end adapted to be engaged by the periphery of a cam (1 when the same is rotated. This cam is held upon a shaft d having its bearing in the standard A and receiving rotary motion through the gear wheel d secured to the opposite end of the shaft and in mesh with the gear a of the main shaft. The cam carries on its outer surface a roller (i mounted upon a stud projecting from the cam, and adapted z 5 to successively enter the slots of the wheel a for the purpose of intermittently rotating said slotted wheel.

To prevent any movement of the wheel 0. beyond the desired point I preferably pro- .vide a sliding block d arranged in the standard and normally pressed outwardly by a spring (i the said block havingaprojecting end d which engages slots or indentations in the sleeve 0. of the wheel at and serves to adjust andlock same against movement. The

block or locking device (1 is arranged in the path of movement of the cam d which cam has an inner cam surface d -whichcontacts with said locking device and releases the block from the indentations of the sleeve as the roller d enters the slots of the wheel a to rotate same.

Within the standard and on the countershaft (1 is a miter gear in mesh with a similar gear secured to the end of a vertical shaft E supported in suitable hearings in said standard. Upon the vertical shaft near the top of the standard is a collar e, shown in Fig. 3, above which is the revolving feed table F rigidly secured to said shaft for the purpose of feeding the caps to the co mpressing mechanism as will presently appear. The standard has the head plate F and the cap plate F secured to said head plate; the latter '55 serving to support the cap compressing mechanism. I

The cap compressing mechanism and means a for op'eratingthe same may be'of any suitable construction, but I preferably use a revolving 6o chuck F supported upon a sleeve F depending from the cap plate F on which the chuck is adapted to revolve. This'chuck is provided within the lower portion with crimping or compressing rollers f, usually three,

normally pressed outwardly and yieldingly held therein by springs f which are located in sockets and which abut against a projection on the blockf in which said rolls are journaled. Arranged to press the blocks inwardly are rocking levers f pivotally se cured to the chuck, the lower endsof which rest against the crimping roller blocks, while the upper ends are adapted to press against cam blocks f located in the chuck, and by which the said lever is rocked on its pivot as will presently appear. end of the chuck is a gear f rotatably held on the sleeve F and which is in mesh with Secured to the upper the gear H journaled-on a stud secured to the cap plate. E the said gear H carrying. a smaller gear L which in turn meshes with the gear L secured to the vertical shaft E, and by which the train of gearing is revolved.

Above the cap plate F and secured to the vertical shaft E is a cam wheel m. As the cam wheel revolves, its cam surface contacts with the end of a lever m pivotally secured to the cap plate and having its end normally retained against the cam surface by a spring m The other or outer end of this lever passes into a boxing m and has its end forked and recessed to form a striking head m adapted to strike the flanged upper end of a hollow sleeve m slidingly held in the sleeve F the said sleeve m having its lower end beveled to operate the cam blocks f when the lever m is rocked on its pivot. The outer end m of the lever by striking the sleeve m forces the same downwardly causing the beveled end to force the blocks f against the rocking levers f thereby forcing the compressing rolls inwardly to crimp the cap around the bottle head after the same has been placed in position. The sleeve m surrounds a centering bar f 6 which passes through said sleeve and the chuck and is ad-' justably held in the boxing m by a nut f and has an enlarged recessed lower end f to receive the cap when the bottle is in position to have the cap compressed.

To retain the cap on the headof the bottle after receiving the same by the cap feeding mechanism I have provided an auxiliary plunger f (see Figs. 3, 9 and 12) which is slidingly held within the centering rod f and preferably provided with a spring f which tends to normally press said plunger downwardly. The small plunger f has a pin f working in a slot in the centering rod f; the

- said pinf serving to limit the throw of the plunger and to prevent any rotary movement thereof. i

The cap feeding mechanism consists ofa revolving table F, secured to the vertical shaft E and formed with a cam groove g which receives a roller g depending from a feed-fl nger '9 Above the revolving table F is supported a stationary feed-plate 9 having a removable plate 9 secured thereto in such manner as to form a passage for the caps as the feed table revolves; the said passage preventing the crowding of said caps by providing" a single passage therefor. The feed-plate g is recessed at g to permit the caps to be placed 4S l k of the jaws serve to place the bottles in upon the revolving table and is provided with an olf-set g"? which serves to guide the feedfinger g as said finger reciprocates back and forth by the action of the cam groove of the provide aretainin g rod h (Fig. 2) which is slidingly held upon the stationary feed-plate g This bar is preferably angular and is provided on the outer end of the angular portion with a roller 77/ which is normally pressed forward by a spring h against a cam 72 This cam is rigidly secured to the vertical shaft E so that as saidshaft revolves the cam will force the retaining bar h against the tension of the spring'h permitting a cap to be fed by the revolving table to the feed-finger g l The revolving table F is provided on its under surface with a cam-actuating ribt' having the cam faces 2''. The cam tacts upon a roller j mounted upon a projecting stud of a sliding block j. This block is slidingly heldin a recess in the head plate F and is normally pressed against the cam 11 by the spring j the said block havingadepending end j passing through a slot in the head plate. On each side of the depending endj of the sliding block and pivotally secured to the underside of the head plate are two arms is andlc'. These arms are arranged to be separated or moved on their pivots by the block j as said block is actuated by the cam t'ot' the revolving feed table. The outer end of the arms is and 7c engage depending lugs or pins 70 of the jaws k and 16 The jaws 71: and k are slidlngly held in the head plate by the stems k fitting in apertures in the head plate and are normally pressed together by springs k arranged in the apertures in the rear of the stems k of said jaws. These jaws have a beveled lower surface 70 and a straight face 10 preferably beveled at the upper edge at 70. The straight edge or face proper alignment to receive the caps by said edge abutting against the shoulder and head of the bottle, as best shown in Fig. 11. This is an important feature for the reason that the bottle holding cups are generally somewhat larger than the bottle to accommodate variations in the diameters of the bottle.

Without such a device the bottles are liable to shift sidewise and consequently will not be in proper position to receive the caps, resulting either in the breaking of the bottle while compressing the cap into engagement with the shoulder or compressing the caps irregularly aroundthe bottle head.

The operation of the machine is as follows: The bottle holder being supplied with hottles and the machinery started, one of the bottle cups or thimbles will rest upon the head 19 of the plunger and be raised by the contact of the cam d with the roller of said plunger. The jaws k and k at this time are in position to place the bottle in proper alignment to receive its cap which has simultaneously been fed forward by the feed-finger 9 The cam t' of the revolving table acting upon the sliding block j forces open the arms 0 and 7a which open the jaws and 70 the said jaws being held open by said cam during the crimping of the caparound the head of the bottle and while said bottles are lowered by the plunger. At the same time that the jaws k and 76 are released from the bottle head, and as the bottle continues to ascend the cap is caught and retained in its proper position on the head by the auxiliary plunger f till it reaches the centering rod f. The compression rollers of the chuck now act upon the cap and compress the same around the-shoulder of the bottle head. The camd, as soon as the cap is compressed, permits the bottle and plunger to be lowered. At the same time the cam releases the locking device 61 from engagement with the slotted wheel a which is then revolved by the roller 01 entering the slots of said wheel. The rotation of the slotted wheel imparts a like movement to the bottle-holder by means of the miter gears a and b, thereby placing another bottle in position to be raised to re-' ceive its cap. This is accomplished by the earn (1 acting upon the spring-pressed plunger b the said cam receiving rotary motion through the counter-shaft CZ, gear (1 and gear a the latter being secured to the driving shaft. i

It will be seen that by the foregoing arrangement, the bottles, caps and compressing mechanism are retained in such relation to each other that the liability of breakage of the bottles is reduced to a minimum. The parts are so adjusted and arranged that the operation of the machine is automatic and continuous.

It is obvious that the number of slots in the wheel a, the number of slots or indentations in said wheel for the engagement of the locking device, and the number of bottle holding cups may be varied, provided the relative adjustment is maintained, andthe required correspondence as to number is observed; r

In Fig. 10 I have illustrated a bottle holding frame having simply radial arms extending, from a central hub, instead of a disk, as shown in the preferred form.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is
