To all ilo/wm it may concern:

Be it known that L'Airos Gunnison, a citizen of the United States, residing rat Brooklyn, in the county of Kings and State of New York, have invented certainnew and useful 'lvlechanisms7 of which the following isl a specification. l

This application constitutes a division of my application for patent for-a bottle filling and sealing machine filed `March 30, 19116, Serial No. 87,805. The present invention is a` novel dwell-motion ,mechanism designed especially with a view to produce dwells of variable extent. It is herein illustrated in connection `with a bottle filling and sealing machine, in which instance it useful to afford pauses of varying duration `so that the machine may be adapted to lill bottles of different sizes; but it maybe used in connection with any `machine in the cycle of operation of which a `dwell is desired. l

arranged to reciprocate, vertically, over the turret a, sliding in ways suitably formed at the front of a housing CZ.

T his machine, which is fully described in my application hereinbefore designated, is'

adapted to fill and seal. bottles varying in capacity, for example, one-fourth pints, onehalf pints, pints and quarts, which `of course involves `filling periods that vary, more or less as these quantitiesvary.` Instead lof l slowing down or `speeding up ,the machine accordingas thefilling period of .the run of bottles to be filled is long or short, i. e., ao-

Cording as the bottles to be filled are large or small, the speed of the machine remains sealing head and bottle head into ,copera tive relation for sealing andA `apply the Closureand then an.,upward or recovery movement-is interrupted during the downward movement by a dwell commensurate 'in ,extent with that of the filling period for" the particular size of bottles being handledk and occurring between the bringing of the bottle and sealing `head together and the closure applying operation. Describing the present invention, now, with reference 'tothe actuation of the structure c by Yway of example;

T hedrive shaft 123 (Figs, 1l and is equipped with aworni 124 meshing withrthe worm portion 125 .of a rotary member including a clutch 126 freely revoluble on a transverse shaft 127. fShaftsg123 and 127 are journaled in the housing `Fixed on the shaft 127V arethe following elementsf` a Fig. 13 shows the controller 159a in side i clutch member 130, spaced peripheral cams 131 and a barrel cani 132.. Onf a `shaft 133 lof the two camsll, having rollerslla bearingthereon and a fork 1349 (Figs.

and 4t) engaging the structure c. In suitable bearings in the `housing is 4:yournaled a vertical shaft 13.5 which, when` oscillated, operates through means not shown to advance the turret a step by step to position the bottles successively under the structure c, or main slide, the same having a crank 138 equipped with a roller 138a (Fig. 2) engag- 5 ing in the groove of the barrel cam 132.

Assuming the shaft 127 to be rotated at constant speed, the relation of the cam 132 to the cams 131 is such that when the latter elevate the main slide the former causes the turret to advance one step to position a bottle under the sealing headb. The cams 131 are formed with oppesite neutral or concentric portions 131a (Figs. 8 and 9) which cause a dwell in the descent of the main slide that is sufficient to permit the filling (through the head b) of bottles having the smallest capacity-standard, e., one-fourth pints. For Vfilling bottles of greater capacity-standard the said dwell in. the present machine is increased .by bringing to a standstill the shaft 1 27 (and the other elements on said. shaft which actuate the moving parts of the machine) to which the cams 131 are fixed. n rlfhis is accomplished, in a way to permit `the dwell to be of variable extent, as follows: Clutch member 130 (which in the present instance is formed integral with the left-hand cam 131, (Fig. 2) contains a Vlatch 139 movable parallel with shaft 127 and normally pressed by a spring 140 contained in the housing 141 (Fig. 8) for the latch toward and into engagement with the,

adjoining face of clutch member 126, which has segmental pockets that are somewhat shallower at 142 than they are at 143 (Fig. 5). According as a latch retractor in the form of a knife 144 pivoted at 145 on a hori- Zonta] axis parallel with the shaft 127 (Figs. 1 and 2) is shifted into or out of the path of a beveled face 139a on the latch, so, assuming the latch to be locking the clutch members 126 and 130 together, it will withdraw the latch when it sweeps around (thus unlocking the clutch members), or leave it undisturbed. On a platform 7 8 of the housing and suitably retained in place by a cover plate 146 (Figs. 2 and 11) Vis arranged to slide parallel with the shaft 127 a block 147; its sliding movement may be effected by the lmanually operated screw 143 swiveled in the housing and having its threading engaged with the block and provided with a handle 1482". It carries a dog 149 springpressed against the periphery of the clutch member 126 and having freely penetrating it a laterally projecting pin 150 on the retractor 144. At'its left side the periphery of the clutch member 126 is continuous or circular, as at 126% but the remainderY of its periphery, somewhat Vreduced in diameter,

has in the present case two diametrically v opposite projections 126 extending each one-third of the distance toward the right side of the clutch member and two other diametrically opposite projections 126c and 126d (each 90o from each projection 126"), the former of which extends two-thirds of Said distance and the latter elea r to the right hand side of said member. lVhen the dog` is arranged so as to bear on surface 126n the knife will be held back, and clutch member 130, being therefore locked to clutch member 126 will, as also shaft 127 and all the mechanisms driven therefrom, be driven thereby, the dwell which occurs in. this case being only that produced by the cam surfaces 131". On shifting the dog the next stage to the right the dwell due to camsurfaees 131n will be augmented by a dwell due to actual stopping of the clutch member 130 and consequently shaft 127 and all parts operated from it, thus: The retraction of the latch is caused by its sweeping around against the knife when the latter is in the retracting position; and always, though the knife immediately be returned to that position after withdrawal to release the latch (to allow it to lock clutch member .130 to clutch member 126), the locked members must make one complete revolution before retraction can be again effected by the knife. In the position of lateral adjustment of they dog now assumed, the clutch member 130 will complete a cycle with clutch member 126 and come to a dwell, the knife being in latch-retracting position because at the end of the revolution the dog is not on a projection but on a low portion of the periphery of clutch member 126; in this the dog will have been repressed (withdrawing the knife) four times by the four projections (but, each time without effect on the latch, of course, because it is out of position to engage the knife). But on the repression of the dog next ensuing after inception of the dwell and consequent release of the latch the latter will enter that pocket 142-143 of clutch member 126 which happens to be opposite, locking the clutch members together for another complete cycle. The pockets are equally spaced and four iu number, so that after four idle impulses have been imparted to the knife by the projections and then, the latch being unlocked,

the fifth impulse occurs and the latch consequently resumes locking position, a dwell of a one-quarter revolution has occurred. On shifting the dog to the next stage the operation isthe same, except that since in this case only two projections 126" and 126i y t are operative the dwells are equal to onehalf a revolution. On shifting the dog to the next stage the operation is again the same, but results in dwells equal to a full revolution. In all cases, as Istated, one complete revolution of clutch member 130 (and all parts driven therefrom) intervenes between dwells due to retraction of the latch.

Thus, the machine is adapted, by manipulating screw 148, for the filling of, for inmechanism fis shown adaptedito effect dwells not onlyof 5,7, and 1 full revolution (for i half pints, pints anduquarts), but 011211, 1,15,

`and 2 full revolutions (for one and fonequarter, one and ones-half- `and two quart bottles) Here the worm wheel 151 has secured thereon byscre-ws, a clutch 1152havingipockets 153like-the pockets of c lutclir 126 already described; part 152 retainsiin place a ring 154 revoluble thereon. 151, 152 and 154001*- respond to the member including thevwormwheel 125 and clutch 126 already described, being likewise revoluble on shaft i127 g but in this case, as described vabove, thev peripheral part (154), which has .the peripheral continuous surface 154a and proj ections154" ble independently of the rest. The other clutch member, ,155,4 `isi-identical to clutch r 'ino' the sorinOf-aressed latch 156, corree l e l j .spending in every respect to latch 139.

Movable in -n'ie1nber 1514-152 parallel with; shaft 127 `is a latch 157 having its right-hand end.; engageable in a single n pocket 158 in the adjoining face of ring-154 and its left-hand end projecting and formed with van inwardly facing: notch 157a `whose inner side is formed by a spring-cushioned pin157".` r1`his notchreceives thewcontinuvousV exterior flange of ythe annular portion 159, embracing thelshaft, of a latch-controller including the thrust-piece 159D extending parallel 'with said shaft and slidi1 able in a'hole 160 penetrating the bearing 161 for the shaft andadapted to enter a recess ornotch162 inthe inner face of a camp29` (when said notch turns into coincidence therewith) under the pressure of a spring 163 housed in said bearing. `Measured in the degreesof va circle, recess 162 A is approximatelyVthe` same distance from latch 156 ,as knife `144 is from the thrust piece 159".of thelcontroller; Viewed from tlie^'l'eft,'shaft 127 rotates clockwise, and the right side of notch 162 issloping, form- Ving a cam, yas at 1624,14`ig. 14.` f

1t wi'llbe` apparent that if the ring 154 remains locked (by latch 157) to member 151-152, these parts then rotating-as one,

the operation would be the same as in the filling-time-centrol mechanism already described, e., there would be no augmented dwell, or a dwell of 34th, 1i or one full revolution, alternating with one full rotation of shaft 132, according as the dog 149 occupied the first, second, third or fourth positions, respectively, from the left with respect to the periphery of ring 154. e

so causing locking move-ment of latch 156 prematurely.

Ring 154 may be kept locked to member 151-152 by latch 157 by turning the keeper 165 into the full line (Fig. 11) position to prevent the latch-controller moving into recess 162 under pressure of spring 163.

It will be noted that each movement of the main slide c is the same, in point of time eX- pended in performing it, whether the ma# chine be adjusted for the filling of large or small bottles; only the intervening pauses are varied, according to the capacity-standard of the run of bottles being handled. A

given number of bottles above the minimum size can therefore be handled in the present machine more quickly than in machines heretofore devised, wherein in order to handle bottles varying in capacity-standard pauses of the proper extent Were obtained by changing the speed of the machine, i. e., so that as the pauses were changed in extent so the time to make each advance Was changed, and in the same proportion. v
