To all whom it may concern: I

Be it known that I, Gnonon A. VVILLIAMS, a citizen of theUnited States, residing at Decatur, in the county of Macon and State of Illinois, have invented a certain new and useful Improvement in Bottle-Capping Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates generally to bottle capping machines and more particularly to certain improvements upon the bottle capping machine patented to me July 18, 1916, No. 1,191,258. The object of this invention is to improve certain features of the machine disclosed in the aforesaid patent and whereby a simpler and cheaper machine is provided and at the same time one which is more convenient of, and eiiicientin operation, and with these objects in view the invention consists in the novel features of construction hereinafter fully described and pointed out in the claims.

In the drawings forminga part of this specification, Fig. 1 is a face view of a machine constructed in accordance with my invention; Fig. 2 is a side view of thesame; Fig. 3 is a vertical sectional elevation taken through the upper portion of the device; Fig. 1 is a horizontal sectional view on the line 4-4: of Fig. 3 Fig. 5 is a sectional view on the line 5-5 of Fig. 3; and Fig. 6 is a detail perspective View of the lever turning finger with the pinion for operating the same; Fig. 7 is a front View of plunger and chuck; Fig. 8 is a side view of same; Fig; 9 is a horizontal section on the line 99 of Fig. 7 Fig. 10 is a detail perspective view of one of the spring plates of the chuck; Fig. 11 is a perspective view of one size of chuck; F ig. 12 is a similar View of a larger size; and Fig. 18 a perspective view of a modification for use in connection with still larger sized caps.

In the practical embodiment of my invention I employ an upright standard 10, the lower portion of which is made hollow or of skeleton formation and is provided with a flat base 11 capable of being bolted or otherwise fastened to the floor. The standard. at its upper end is formed with an arm or boss 12, and also with an intermediateb'oss 13, and a lower boss 14:, all of said hossesbjeing in vertical alignment. ,The lower boss letis bored to receive a sleeve nut15' or thrust member through which works the screw shaft 16 carrying a bottlesupport 17 at its upper end. This supportis provi'ded'with lateral guide extensions 17 whichem brace the standard and prevent-the support turning. A hand wheel 18isrigidly connected pivoted at 20, the rear member thereof. loeing weighted as shown at 2 1 in orderjto maintain the bifurcated forward fportio'n constantly in contact with the lowerend of the threaded sleeve or nut, ai dlwheri the lever 19 is rocked, the sleeve With the threadedshaft is moved upwardly andconsequently the bottle upon the 'support. will be raised vertically. The lever is rocked hy means of the arm 22 actuated by the treadle 23 mounted upon the rock shaft 24. shaft 24 projects laterally from both 'sides of the standard 10, whereasthe actuating arm 22 isarranged centrally of the standard as is also the lever 19. By having the shaft I 24 of considerable length, and havingithe ends extend laterally upon opposite sides, it

is possible to mount the treadle 23 upon either end, or both ends if preferred, andl in N Fig. 1 1 have shown the machine as equipped with two treadles so that the operator {can use both feet-.[ Eachtrea dle is provided with a rest or'stop 25 at the free end thereof and into which the heel fits." The' treadlj23 is curved as shown, so that, in its normal position the free end thereof eXtendsforwa-rd and upwardly and by'kicking straightout while the foot is firmlypressed upon vjsaid treadle, the operation isrendered quickfand 1' v I c. @7100 Byhaving the shaft 24 the .properlength the treadle 23 will be so positioned as "to be in convenient reach of the operator when sitting directly in front of"the machine,

which is the correct operative position; If only one trea'dle is used it cztnjhej'arrang'ed either 'uponthe right side or leftsidefasthe operator may prefer.'

The bottle rests, upon the support 17 and is pos1tionedby'means of a holder or gauge 26 curved or angled to receive various shapes of bottlesfand having rearwardly extending and forth so as to properly center any size or shape of bottle, and several sizes of -may be provided.

The boss 13 is bored vertically and faced off to receive the upper portion of the plunger 29, thisupper portion being curved to correspond to the bored portion of the boss and the front face thereof is flattened as shown at 39 and a plate 31 is bolted to the'boss 13 for the purpose of holding the plunger properly positioned in the boss but at the same time permitting the free and easy vertical movement within the same.

A shaft 32 is rigidly fixed in the upper end of the plunger and extends vertically upward through a nut 33 screwed in the threaded bore of the upper boss 12,'and surrounding the shaft 32 is a coil spring 34, the upper end thereof bearing against the nut 33 While the lower end thereof bears against a collar 35 rigidly attached to the shaft as indicated in the drawings. caps to be applied tothe bottles are made of sheet metal in accordance with my Pat- :ent No. 1,108,959 granted September 1, 1914.

guides These capsembodying a slotted sheet metal skirt, an encircling ring and a wire lever for contracting the ring and skirt upon the mouth of a bottle.

1L casting or forging 36 is sometimes bolted to the rear face of the lower portion of the plunger, the lower end of this casting being curved as indicated at 37 to serve as a guide for the bottle. This casting 36 is adapted for use only with the largest. size bottle caps and in order to provide for the efficient operation of this machinev with smaller. sized bottle caps I provide a chuck 39. Various types of chucks are shown in Figs. ,7-13 inclusive and the smaller sizes thereof can be used in connection with the casting 36 but in some instances the dependv ing guide portion 37 ofthe casting 36 will be omitted. Eachchuck 39 comprises an upper portion which is connected 'to the lower end of the plunger 29 and a' lower portion which serves as a guide for the bot tleyand between the upper andlower portions there are openings at each side across which are arranged spring gripping plates 60 which serve to hold the bottle cap in its proper pos ition in the chuck. Each spring plate 60 has an outwardly projecting lip 61 at'the forward end and also an outwardly extending flange 62 along the lower forward portion, said plate 60 being cut away at 63 intermediate its ends to render the forward portion :more resilient. These plates are se- The the sides of the chuck. The lip 61 projects inwardly and downwardly as shown in order to prevent any dislocation of the cap after it' has once been properly positioned in the chuck. In the construction ofchuck shown in Fig. 13 the depending guide portion 39 is omitted and it will be understood that this form of chuck is employed for use in connection with the largest sized bottle caps the caps being held between the spring gripping plates 60, and bottle guided by 37.

The casting 36 has a shaft 42 journaled therein and a stud 4E3 fined; therein, the shaft 42 having a pinion 4s: upon its outer end with which mesh the teeth 4-5 of. the segmental gear 46 pivoted upon the shaft 43. This segmental gear also has teeth i? which mesh with the rack 48 secured in proper position upon the standard 10. The inner end of the shaft 42 carries the capping finger 49 which is adapted to engage the lever of the bottle cap and throw the same down for the purpose of fastening the cap upon the mouth of the bottle and this operation takes place.

- throwing down the lever of the bottle cap and uickl 1 and easil r fastenin the same I upon the mouth of the bottle. The bottle caps are thrown into the hopper .50, fastened at the upper side of the standard 10 and descend into the chute 51 which extends adjacent the chuck. From here they are picked one at atimeand inserted by hand into the chuck with the lever ofthe cap turned up. It will be noted that the lower end of the plunger 29 has a forwardly projecting inclined lip 52 and the upper portions of the chucks 39 which are attached to the lower end of the plunger are also provided with forwardly projecting inclined lips 52 which coincide with and constitute a continuation of the lip 52 and these forwardly projecting inclined lips are notched centrally as shown at 52 the purpose of which is to acc0mmo date the upturned lever of the cap. The capping finger 49 normally rests against the forwardly projecting lip as most clearly shown in Fig. 2 and when the cap is pro-perly inserted into the chuck the upwardly projecting lever will rest in the central notch 52 and will be adjacent to the finger l9. After the cap hasbeen properly insert ed, the treadle is operated causing the bottle support with the bottle thereon-to be moved upwardly and this bottle being properly centered by contacting with the rest. 26- themouth of the bottle will he directed into the completing the czt-rpping operation. By the employment of different sized chucks i able to use one machine for applying all sizes of bottle caps.

By having the boss 13 open at the front, an easy method of inserting and removing the plunger is provided, and at the same time the plate 31 hearing against the flat face of the plunger maintains saidplunger and chuck in. a perfectly true position at all times. In practice I prefer to employ a guard housing 56 which is attached to the casting 36 tor the purpose of enveloping the pinion, segment and rack and thereby eliminate the danger of the operator get-ting a linger caught in the gearing during the operation of the machine. 7

it will thus be seen that I provide an improved construction of bottle capping ma chine which can be operated from either side oi the machine or from both sides of the machine at the same time and one in which certain of the parts are interchangeable thus giving the machine as a Whole a more extended usefulness.

Having thus described my invention, what i claim is l. lira bottle capping machine, the com 'hination with a standard, of a bottle support having guiding extensions embracing a portion of said standard, a screw shaft, a threaded nut through which said shaft passes, said threaded nut being movable vertically in the standard, a hand wheel coir nected to the upper end of said threaded nut,

'21 bifurcated leveradapted to straddle the central notch, andspring plates attached to the sides of the chuck between the upper and lower portions, said plates being secured at the rear ends, their forward ends being resilient. i

In testimony whereof, I hereunto alfix my signature.
