1 Claim.
The present invention relates to devices for tightening a cord around an article to be sealed and for compressing a seal around said cord.
In the accompanying drawings the invention is disclosed in a concrete and now preferred form in which:
Fig. l is a side elevation of a device embodying the invention showing the parts in the position they occupy before the beginning of the pulling operation;
Fig. 2 is a view looking in the direction of arrow 2 of Fig. 1 with parts removed substantially along section line 22 of Fig. 1;
Fig. 3 is a View of a portion of Fig. 1 showing the parts in the position they occupy after the cord has been pulled tight; and
Fig. 4 is a view similar to Fig. 3 showing the parts in the position they occupy after the seal has been compressed.
The article to be sealed is, in this instance, a money bag I such as is used by banks and other institutions for the shipment of coin. It is customary to tighten mouth 2 of said bag by means of a cord 3, which may be doubled back upon itself to provide two or more strands, the pulling action being effected by drawing the cord through a seal 4 of compressible material, and to thereafter compress the seal. Sometimes a gripping member as '5, of non-compressible material, is interposed between the seal and the bag, all as explained in Patent No. 2,163,660 dated June 27, 1939. The pulling operation has heretofore usually been carried out by hand and, as the gathered material of mouth 2 of the bag is required to be highly constricted, it is easy to overpull the cord and break ,it. Or, in cases where a tool is employed both to pull the cord and to compress the seal, several distinct manipulations of the tool are necessary to perform the double operation.
It is the main object and feature of this invention to overcome the above disadvantages, and to provide a device for pulling the cord tightly without overpulling and breaking it, and to coordinate a pulling device of this character with seal compressing jaws in such a way that a single movement of a handle will actuate both the pulling device and the jaws.
6 is a platform for supporting bag I in an upstanding position, said platform also having an upright support I on which latter a carrying member 8 is mounted. Said carrying member 8 is slidable or adjustable in a vertical direction on the upright support so as to accommodate it to varying sizes of bags, and when so adjusted can be fixed in the desired position by means of binding screw 9. Mounted upon the carrying member is a cord pulling implement Ifl consisting here in part of a rotatable member II having a cord receiving surface I2. I3 is a handle whereby said rotatable member isturned around its center I4. Associated with said rotatable member is a yieldable cord gripping member taking here the form of a plunger I5, having a gripping portion I6 and held in two bearings I'I. I8 indicates a spring acting against one of said bearings and against a transverse pin I9 carried by the plunger. The function of the spring is to urge the gripping member away from rotatable member II. Pivotally mounted on handle I3 is a cam 20 to engage the upper end of plunger I5 to depress the same against the action of the spring to thereby grip the cord against surface I2 of the rotatable member. 2| is an adjustable abutment member, carried by one of the bearings II, which by engagement with stop 22 of the gripping member prevents the latter from gripping the cord too tightly.
23 and 24 indicate two jaws, on carrying mem ber 8, which when closed serve to compress the seal 4 around the cord. Jaw 23 is here stationary and jaw 24 is pivoted at 25, and a spring 26 tends to urge the jaws into an open position.
Suitable actuating and operating means or members are interposed between the pulling implement and the jaws. In the present instance, rotatable member II is provided with a cam 21 that acts on roller 28 of lever 29, pivoted at 30 on the carrying member, the other end 3| of said lever actingto press on top of movable jaw 24 to close said jaws to compress the seal when urged to do so by cam 21. Cam 2! is preferably shaped to impart no movement to lever 29 during initial rotation of member II, or at least no effective movement, but to close the jaws only after the pulling implement has operated to pull the cord.
The material of the mouth of the bag is gathered together and the cord is slipped over it and pulled more or less tightly by drawing said cord through the seal. The bag is then placed on pedestal 6, seal 4 is placed between jaws 23 and 24, and cord 3 is placed on cord receiving surface I2 of the pulling implement. It will be understood that both hands of the operator are now free. Handle I3 and the handle of cam 20 are now grasped thereby causing the yielding cord gripping member to engage the cord. Handle I3 is now turned thereby rotating member I I and the yieldable gripping member thereby pulling the cord through seal 4 and tightening said cord around the bag. Seal 4 is prevented from following the cord by surfaces 32 of the carrying member and is therefore stationary. During this tightening action, the jaws remain open because cam 21, although rotating with member H and handle 13, has not yet commenced to act sufl'iciently on lever 29. When the cord has been placed under the requisite tension, the gripping member begins to yield and to slip with respect to the cord. Cam 2'! now acts to close jaws 23 and 24 thereby compressing seal 4. It will thus be seen that there are interrelated means associated with the pulling implement and the jaws to sequentially and uninterruptedly actuate the pulling implement and the jaws, only in the order named.
I claim:
A device for tightening a cord around an article to be sealed by pulling said cord through a seal of compressible material and for compressing said seal, including: a pair of jaws to receive a seal through which latter the cord passes, a spring to urge said jaws into open position, a rotatable member having a cord receiving surface, a yieldable cord gripping member mounted to move with said rotatable member and to press the cord against said receiving surface, a cam movable with said rotatable member, and means, between said cam and jaws, actuated by said cam to close the jaws.
