.'Jersey City, in the county of Hudson and r is directly secured to a b ott bar 2 isheldyieldingly at-its highest-point;

State of New Jersey, have invented certain Improvements in Machines for Sealing Bot-- tles, of which the followingis a specification,

This invention relates to certain improvements in what is generally known as the sealing head, or that part of the machine which embodies the devices whereb a sealing cap it head having thereon an annular shoulder, as will hereinafter fully appear. In the descriptionof the said invention which follows, reference is made to the accompanying drawings forming a part hereof, and in which,

Figure 1 is an exterior side elevation of the' improved bottle sealing machine. Fig. 2 is an enlarged partly sectional elevation of the sealing head alone; Fi .3 is an underside view of Fig. 2. Fig. 4 1s a still further enlarged section of a art of Fig. 2. Fig. 5 is aperspective view 0 one of a system of cap indenting bolts forming parts of the sealing head.

Referring now to the drawing, 1 is the columnar stand of the machine, and 2a vertically movin bar situated within the coluinnar stand. Due to 'a spring mechanism (not shown) within'the columnar stand, the

as shown in Fig. 1. The sealing head 1s fas tened to the upper end of the bar 2, as shown in Fig. 1, audit consists of a tubular block 3 having a bracket a, whereby it is attached rigidly to the bar 2 by means of a nut. At the lower end and forming a art of the sealing head, is a guide I; adapte( in the up-anddown movement of the sealing head toslide within a groove formed in a collar 0 clamped around the top of the columnar stand 1," as shown in Fig. 1. i

5 is a treadle whereby downward motion of the bar 2, together with the sealing head, is effected.

end by a hollow screw cape; and between the said cap and the end of the block is clamped an annular disk 7 to guide the stem 9 which terminates at its lower end in a hollow conical enlargement e thepurpose of which will The means of attachment be tween the treadle and the bar 2 are not.

I hereinafter appear. The lower end of the tubular block 3 is also enlar ed and bored to re- 1 ceive the annulus 10 whic is held in place by an exteriorlythreailed ring 12. The central opening in theannulus 10 is of tapering or conical form, and its angle of inclination corresponds substantially with that of the en; largement e of the stem 9 as shown in Figs. 2 an 4.

13 is a collar screwed u on the stem 9, ada ted to fit loosely wit in the tubular bloc 3.- This collar when in its lowest position rests upon the portion of the annulus 10 which projects inwardfand beyond the inner circumference or here of the block 3; and extended between the said collar and the disk 7 is a spiral sprin 15. The bottom of the enlargement e of t e stem 9 is bored to form the cavity f which is of such a diameter and depth as will freely admit of the. entrance thereto of a sealin cap, as shown in Fig. 4 wherein the cap is enoted by A; and within the said stem and supported by a pin q isa spring-held permanent ma 'et 17 '(shown only m Fig. 2) the lower an of which, when in its lowest position, projects slightly beond the surroundingsurface oi the said enargement. The ofiiceof the magnet is to hold a. sealing ca within the cavity f before the application 0 the cap to a bottle head.

19, 19 are bolts resting inr'adially disposed holes which extend through the wall of the enlargement e ofthe stem 3 in an inclined position as shown in Figs. 2 and 4., and the said bolts are held with their ends or points flush withthe conical inner surface of the cavity f, by-rneans of's )rings 72, as shown in Figs. 2 and 4. The boits 19 are-showmas'of rectangular cross section and as'havfing chisel points, but I do not confine myself to the use of bolts'of any particular shape, as it is only necessary that they should be adapted when forced inward, to properly indent the skirt of the sealing cap immediately below the shoulder of the bottle head in thesealing operation hereinafter described; nor do 1 limit myself to the employment of any articular description of springs h, and those i lustrated in the drawing are of the plate order and notched'at'their ends to fit over the bolts which are grooved to receive'them, as shown particularlyin Fig. 5. Invertical alinement with each-bf the bolts.l9, the wall of the annulus is bored, and thelholes :1 thereby Q ceases produced are inclined so as to be at right an- I spends in construction with a cap describedgie with the inner conical surface of the an nulus, as shown-in Fi s. 2 and 4.

20, are stems which occupy the holes 2' and are adapted to have a longitudinal movement therein, the said movement beinglimited in an outward direction by the heads j,

" I and in an inward direction by the collars 7c;

and between the collars 7c and plugs m are laced the compressed spiral springs 21. he positiorr of the stems when the machine is at rest is shown in Fig. 2, and their position during the sealing operation ls'represented inFigAe. I I

23 is an ordinary bottle seat and 2d a rest whereby the-bottle is centralized with re- Supposinv a sea 'ng cap tobe held by the magnet within the cavity f in the enlargement of the stein 9, and a bottle to be stand 'ing on the" seat 23, the sealing operation consists in ressing down the treadle 5 which causest e sealing head to descend and the sealing cap to be laced on the bottle head which in Fig. 4 is denoted by B. When the joint-forming gasket is fully compressed in the sealing cap, further downward movement of'the stem 9 is sus ended, but the descent of the tubular bloc 3 carryin the annulus 10 with its stems,20, continues, its

movement being op osedbnly bythe-spiral s ring 15 which is ihrthei compressed. In

t secondary operation of the machine, the' heads of the stems 20 engage with the ends.

of the bolts 19 which are forced inward'and their points made to indent the skirt of the cap directly under the shoulder of the bottle a head, as shown in Fig. 4. Upon the release of the treadle, the indenting bolts 19 will leave the cap, and as soon as the spring 15 has expanded to its original length, the stem .9 will rise leaving the sealed bottle on. the

. seat 23.

Owing to stei'ns 20 being backed by the springs 21 the pressure exerted on the bottle head by the indentation ofthe skirt of the cap can never be greater than that due to the strength of' tlle said springs; and in the construction of the machine such springs are selected as will yield when the required force to properly seal the bottle is reached, and the breaka e of .iiottles thereby prevented.

It wi l bsiinderstood that as the indenting bolts 19 operate independentl of each other, irregularities in form of the ottle head do not affect the sealing o eration, the indentations being deeper or s iallower according to v the shape of the bottle head at the particular point against which the skirt of the cap is pressed.

' The sealing cap, shown in Fig. 4, corresaid cavit same, com ined with a system of s ring-held stems placed eXteriorly of the said olts, and means whereby the said stems may be brought into contact with the ends of the said bolts and claimed by me in my application for Letters Patent filedon the 13th day of September, 1907, underSerial Number 392,702, but

the present invention may be used in connection with any other construction of cap where the diameter of the ca has to be reduced to bring a ortion of the s irt of the same closely under t is shoulder of the bottle head in a bottle sealing operation.

I claim as m invention,-

1. In a macfiine for sealing bottles, 'a sealing head having a cavity for the reception of a sealing cap and a system of independentl acting spring-held bolts which surround tfie and are adapted to enter the and thereby force their pointsinto the said cavity, substantially as, and for the purpose specified.

2. In a machine for sealing bottles a sealing head in which are combined a tubular block carr ing an annulus having a conical inner sur ace with a system of inclined spring-held stems circi'nnferentially arranged within its wall, a sarin -held stem situated within the tubular bloc with a cap cavity at its end, and a s stem of cap-indenting bolts within the wal surrounding the cavity which are normally below and in vertical alinment with the said stems, and adapted to be brou ht into contact with the same,

substantial y as, and for the purpose specified.

b ock, having a cap cavity at its end, a system of bolts which penetrate the wall which surrounds the ca cavity and are in vertical alinement with the said stems, and mechanism to yieldingly hold the'points of the bolts practically within the said wall, the said tuular block with its s ring-held stems being adapted for downwar movement independently of the spring-held bolts, when the said stems will engage with the outer ends of the spring-held bolts and thereby force their inner ends or points into the cap cavity, sub-- stantially as, and for the ur oses ecified.
