CORK-STAPLING MACHINE.

Specification of Letters Patent. Application filed July 6, 1911. Serial No. 637,064.

Patented J ne 10, 1913.

To all whomiit may concern Be it known that we, JULIUS G. Hansen and 'MARTIN R. ScHAmn, both citizens of the United States, and residents of the city of Reading, in the county of Berks and State -of Pennsylvania, have invented certain new and useful Improvements in Cork-stapling Machines,-of which the following is a specification. r

Our invention relates to a machine especially adapted for applying reinforcing staples to corks or bottle stoppers for the purpose of facilitating their withdrawal from bottles-or the like.

The improved machine is fully described in connection with the accompanying drawings, and the.novel features and combinations of parts, are definitely pointed out in the subjoined claims.

Figure 1 is a front elevation without the cover plate; certain of the parts being removed, and a portion of one of the outer guide plates being broken away to more clearly show the attached inner guide plate.

The" parts'are shown in normal starting position. Fig. 2 is mainly a central longitudinal section on the line 22 of Fig. 1, certain of the parts or portions thereof being shown full. Fig.- 3 is a similar view to Fig.

1, but showing only the principal operating parts, and these in the position assume% at 1 4 is a cross-sectional view on the line 4 4 of Figs. 1, 2 and 3; the movlng parts being in the position indicated in Fig. 3. Figs.

5 and 6 are separate views of the combined .guide plates, ready to be adjust-ably secured in the casing. Figs. 7 and 8 are additional views of machine details. Figs. 9 and 10 show the cork as cut preliminary to applying the staple; and Figs. 11 and 12 snow the finished product, the partial cross-section shown in Fig. 11 being taken on the line 1111 of Fig. 12. Fig. 13 is a separate view of the staple. Fig. 14 is an end view of the removable staple carrier.

The improved article of manufacture which is the particular product of our machine, comprises an ordinary cork 2, and a Wirestaple

thelegs

4, 4 and the inturned ends 4* 4 of which, are driven into the body of the cork, so as to rigidly unite it therewith and also serve as a convenient means for extracting the reinforced cork from the bottle. The staples are specially shaped to properly adapt them to the. purpose, the legs .the cork when driven into the latter.

4, 4 being outwardly inclined as shown so as tospread the inturned ends and make ticable the required straddling of'the cork; the angular bend of the inturned ends being such as to cause them to hook upward into To enable the wire staple to be thus united with the cork material in a. satisfactory manner, we have also found it to be practically essential that the surface material of the cork be preliminarily cut as indicated at 5, 5, so as to permit of properly embedding the longitudinally-arranged staple legs without unduly straining or distorting the cork; and that these cuts, or severings of the surface material, should preferably be parallel and arranged tov gradually run out at terminal points 6, 6 located well above the base of the cork and approximately where the rightangled ends 4 4 of the staple are adapted to pass radially into the cork in thereafter securing the staple to the latter. When thus driven into the properly cut cork, the staple wire is very firmly held and satisfactorily covered by the cork, while the latteris free to be automatically efi'ecte in their proper sequence and time; and we will now specifi cally describe themachine which we have invented and developed for such purpose, as shown in the drawings.

The machine casing comprises a base por-' tion 10- carrying a vertical wall plate 11 which is provided with forwardly projecting marginal flanges 12, and with a plunger,

head 13. Upon the base 10 is provided a supporting block or anvil 15 for the cork 2; said block having suitable cork supporting posts 16, rising above its top face; being provided with oppositely arranged longitudinal grooves 17 for engaging the guide plates hereinafter described; and being secured to the base 10 by slot-engaged screws 18 as shown, so as to permit of its being readily adjusted for the purpose of accurately positioning corks of one,.,size or another to the plane 20 of the staple guide-way.

The staples whichare to be applied to the corks soplaced, are carried upon a horizontal feed bracket 21 which extends rearwardly from the casing wall 11; said wall being provided with an opening 22 for the inner end of the feed bracket and for the passage of the staples therethrough to the guide Way and operating plane 20. In stead of placing the staples directly upon this feed bracket they are preferably strung upon a separate sheet-metal carrier 23 in connection with which they are supplied to the machine user; said carrier being slipped upon the feed bracket 21, and firmly held thereon, as shown, by a tongue 24 which is fixed at one end to the bracket and the free portion of which engages down-turned loops 25 of the carrier. The string of staples is pressed toward the guide-way 20 of the casing by a pusher 26 slidable on said carrier by the action of a spring band 27 or the like; the forward staple being thus moved into said guide-way 20 at the end of each upward movement of the central staple-driver 30 hereinafter described. This central staple-driver 30 is carried by an operating plunger 31, which is guided in the plunger-head 13 and normally raised by a spring 32. The operating downward movement of the plunger is elfected either by hand as provided for in the construction indicated, or otherwise as desired; a regular power movement being of course preferable when convenient, thereby leaving the operator free to merely supply new corks and replace the staple feed carrier when required. This plunger 31 not-only carries the central staple-driver 30 but also a series of cooperating devices, being provided with" a rigid cross-yoke 35, as shown, to which said devices are attached, in pairs, at opposite sides of the central driver 30. Referring particularly to Fig. 3 where they are shown as pivotally carried by the cross-.

yoke 35, without. indicating the guiding means which control their movements, these devices comprise the following: First, at:- tached to the outer ends of the yoke, are knife hangers 36, at the lower ends of which are adjustably secured knife blades 37 the curved cutting edges 38 of which are adapted to smoothly make the longitudinal cuts 5 in the corks; as shown the blades are adjustable in the lower ends of the hangers so that they can be swung upward or downward to determined operating positions, and are locked in such posit-ion by a suitable clamping plate and set screws 40. Second, there are side-driver hangers 45, pivoted at 46, 16 to the yoke 35, and having their lower ends provided with driver faces47 adapted to operate upon the staple-legs 1 to press them into the longitudinal cuts 5 in the cork. Third, the stample-engaging hangers 50, which are pivoted at 51, 51 to the yoke, are provided at their lower ends with finger-pins 52 which are shaped to engage the corners of the inwardly-bent staple-legs; said hangers serving to positively hold and control-each staple during its whole downward movement, and thereafter releasing the same to the free action of the side drivers; and also serving as shown, to spread the legs of the descending staple sufficiently to insure the inturned ends-,4. clearing the top portion of the cork as they are moved downward to closin -together position on the latter. The describediactions of the several devices thus carried by the plunger 31, are automatically effected in proper sequence and cooperation, during the "descent of the plunger, by guiding means adapted to properly engage and control the same, as" will now be explained. These guiding means comprise connected inner and

outer plates

60 and 61 on each side of the axis of the machine; said plates in each ward the central axis so as to cause the finger-pin 52 from the staple-leg before the side-driver 47 operates to close together the staple legs.

The combined side-plates 60 and .61, are adapted tobe jointly adjusted laterally in the casing, so as to move the controlling guide slots thereof inward or outward as required to suit one or another size of cork which is to be operated upon, thus conveniently adapting the machine to operate satisfactorily upon a'certain range ofsizes instead of a. single size only. This adjustment is provided for as shown, by forming rearwardly projecting top and bottom lugs 68, 69 on the inner plate 60, which are engaged by adjusting

screws

70, 71 extending through the casing flanges 12 and conveniently' accessible to the operator. The com binedplates, as well as the other interior 25 stroke.

and the removable front wall 75 thereof,

by providing the inner faces of both walls with suitable bearings therefor which retain the parts in determined position when the removable front wall or cover-plate 75 is secured to the main casing by suitable screwsat 76. l

In order to automatically discharge the corks from the machine, immediately after each stapling operation is completed, we provide a discharging hammer 80 in the form of a bell-crank; said hammer being pivoted at '81, near the base of the casing, and having a trigger arm 82 which rests upon said base when the hammer is withdrawn. This hammer is automatically operated to discharge a cork after the completion of each downward movement of the plunger, by means of a looped operating rod 83.; the upper ends 84 of said rod being pivotally connected to a cross-pin 85 in the upper portion of said plunger, while the looped lower end 88 is adapted to engage the trigger-arm 82 at the finish of the plunger This engagement is positively insured by forming the trigger arm 82 with a hooked end 86 having a curved upper surface on which the loop 88 of the descending connecting rod 83 rides outward, springing the rod from the intermediate fixed guide 87, until the 100 is free to get under the trigger arm as cl arly shown in Fig. 2. The first rising movement of the plunger then swings the discharging hammer to the position indicated in dotted lines, thereby discharging the stapled cork; after which the hammer returns to its normal position and is ready for the succeeding operation.

The ends of the central staple driver 30 and right and left drivers 47, are properly grooved, as indicated, so as to snugly engage the staple wire on which they operate. The notch 90 shown in the yoke 35, is provided to engage a locking hook, not shown, whereby the plunger and connected parts may be firmly held in lowered position, as for shipping- These and other features of minor importance may obviously be omitted without affecting the essential operation of the machine, and the particular construction and arrangement of the main features as specifically described, may be readily modified without materially "changing such operation, which may be bri-efl restated as follows: The cork being place in position upon the properly fixed anvil block, and the charged staple-feed carrier 23 having been secured on the feed bracket 21, a single downward movement of the lunger-31 and 0 its attached devices efiects al the required Operations in. proper succession and 006peration: The finger-pins 52 of the hangers 50, which engage the bent ends of the staple pushed forward into the guide-way plane 520, positively control the staple during its downward movement, spreading the

legs

4, 4 before they reach the top of the cork,- and releasing them when they are'in position to be driven into it. The knives 37, which are in advance of the staple, have meanwhile made the clean parallel cuts 5,5 in the surface of the cork. The right and left side drivers '47, 47 which have been lowered to proper positions, are closed together to drive the staple legs into the cuts 5, 5 and their bent ends into the solid body of'the cork adjacent the ends of the cuts 5 and with a slight upward slant as indicated. As the plunger is released after the completion of these operations, thedischarging hammer 80, which has been engaged by the looped connecting rod 83, is thrown forward to discharge the stapled cork and then returns to normal position. As the central driver 30 rises above the inner end of the '35 feed bracket 21 a new staple is pushed forward into the guide-Way plane 20 and the machine is ready for a repetition of the described operations.
