UNITED STATES PATENT OFFICE BOTTLE-CAPPING' MACHINE WITH MEANS FOR CONTROLLING THE FORCE ON CAP- PIN G PLUNGERS Nelson Vincent Burdin, Coventry, England, assignor-to Scotts- Engineering (Newport) Limited, Newport, England Application February 28, 19,149.,v Serial No, 78,695
vide a means of applying a load to thecapping head by resilient means, which means can be loaded and released when desired to effect the capping operation, without undue variation of strain being incurred by the driving mechanism of the machine thus obtaining an improved output.
A further object is to provide a construction whereby resilient means operate on the bottles to minimise the possibility of fracture thereof.
In the accompanying drawings,
Figure 1 is a sectional elevation of a bottle capping machine according to the present invention, and
Figures 2 and 3 are elevations on an enlarged scale of cams employed in said machine.
Referring to the drawings, a horizontal driven cam shaft 4 is provided with two cams 5, 6 adapted to engage the lower ends of vertically disposed followers 1, 8. One cam '5, the profile of which has a gradual rise commencing from the point 9 (Figure 2), bears against the vertical follower I that engages the lower end of a vertically disposed compression spring I0. The other earn which features a concentric portion II and fiat portion I2 (Figure 3) along its profile engages the other vertical follower 8, which follower is pivotally secured at its upper end to one end of a substantially centrally pivoted lever I3 pivoted at I4 to a support I5 on the machine frame l6, which lever I3 has pivoted at its other end vertical links [1, these links being pivotally connected at their lower ends to a cap 18 which abuts the upper end of the compression spring Ill. The cap I8 also slidably engages and is coupled to the extension I9 of the follower I. The extension I9 is adjustable axially with respect to the follower I.
A beam 20 pivoted on the machine frame I6 engages at one end the upper end of the compression spring Ill through the cap I8 and at its other end bears on the movable capping member 2I of the capping head 22.
The arrangement is such that as the cam shaft 4 is rotated the gradual rise of the cam 5 causes a compressive force to be exerted on the spring I0 from its lower end, whilst the concentric portion I I of the profile of the cam 3 prevents extension of the upper end of the spring ID by reason of the follower 8, pivoted lever I3 and links ll. However, upon the follower 8 engaging the stepped down concentric portion H the spring II] is released a limited degree for initial operation of the capping head 22 by means of the pivoted beam 20, whilst upon the follower 8 engaging the portion I2 of the profile of the cam 6 the spring I0 is further released to effect a final operation of the capping head 22.
Thus it will be seen that whereas the cam shaft 4 can be driven by a relatively low powered driving means to gradually load the spring III, the said spring I0 is released to exert its accumulated load for operation of the capping head 22.
The compression spring It! also serves the purpose of maintaining both followers 1 and 8 in contact with their respective cams 5, 6 during the main portion of the working cycle.
The follower 8 which engages the second or release cam 6 may be provided along its length with a suitable screw adjustment 23 so that its effective length may be varied and so adjust the mechanism. By varying the angular position of the two cams 5, B on the cam shaft 4 with respect to one another, the timing of the release of the spring I0 can be adjusted, which in turn will time the operation of the capping head 22 with respect to other operations performed by the machine.
I claim:

In a bottle capping machine comprising a movable capping member, a compression spring, a rotary cam shaft, a cam member mounted on said shaft, a cam follower moved by said cam member to co-act with one end of the compression spring to gradually load said compression spring, a second cam mounted on said rotary cam shaft, a second cam follower moved by said second cam member, a pivoted linkage one end of which is connected to said second cam follower, the other end of said linkage co-acting with the other end of the compression spring to release the load on said spring at a predetermined moment and a pivoted beam one end of which co-acts with the compression spring to cause said beam to move about its pivot to operate the movable capping member of the capping head of the machine.
