BOX-STRATPPING root. V
Application filed May 21,
To all whom it may concern:
Be it known that I, DANIEL J. OConnon, a citizen of the United States, and a resident of the city, county, and State of New York, (whose post-oflice address is 437 Eleventh Avenue, New York city,) have invented certain new and useful Improvements in Box- Strapping Tools, of which the following is a specification.
My invention relates to that class of boxstrapping tools in which the free ends of box-strapping or other materiahare drawn together under desired tension by means of a sliding block or gripping carriage travelling along a fixed track toward a stationary gripping device, or by drawing said track and gripping device toward said block, as tension requires.
The object of my invention is to do away with the rack and pinion mechanism frequently used in tools of this class, and to bring about the necessary stretching of the strapping by means of a drum and cable mechanism, whereby the efliciency and simplicity of the tool are much improved and the tool itself renderedmore durable and reliable.
One form of my invention is shown in the accompanying drawings in which Figure 1, is a side view.
Figure 2, is a top plan.
Figure 3, is an enlarged detail of the drum.
Figure i, is a cross section on line 4-4 of Figure 1.
Figure 5, is a top plan of the drum showing the cable wound. thereon.
I Same letters indicate similar parts in the diflerent drawings.
A. B, aretwo gripping blocks, of substantially similar construction but facing in opposite directions. Both of these blocks are provided with a cam-lever a, a, pivoted to the block at b, b, and having a gripping cam surface 0, 0, adapted to grip a free end of box-strapping when inserted thereunder against the rest (Z, (Z, forming part of the base of the block. This pressing action is constant, being caused by the coiled spring 6, e, wound around the pivot of the'leve'r and secured to the wall ofthe block. This feature is of well-known construction.
The other portion of each block is slotted as at f, 1, Figure A, to receive a slide bar,
preferably T-shaped, and which is prefer- Specification of Letters Patent;

ably secured to block 13, as at g, While it may slide freely through the slot in block A. This slide bar, G, is provided, preferably, with a longitudinal trough h, in which runs the cable D, one end of which is fastened to the slide bar by the same fastening g which holds the latter to the block B. In this way the pull of the cable as it winds, exert-s balanced force upon block and slide during the tightening operation.
E is a sliding'carriage, firmly secured to the slide block A, as by screw j, or in other suitable manner, and slotted as at is, to permit free passage to the slide bar 0, and the cable D. In the centre of this carriage is mounted by shaft Z, a drum F, the periphery of which is groove-d to receive the cable and each arm of the fork of the handle G, is
provided with a spring-controlled dog, a, n,the two dogs acting in unison to engage the corresponding. teeth on opposite sides of the drum, and thus cause the same to revolve evenly, the pressure on both sides being the same.
The drum is prevented from turning backward under tensional strain, when the dogs are drawn back by the handle G, to catch another toothof the drum F, by a spring -controlled pin, 22, p, projecting through the sidewall of the carriage E, and held under pressure by the spring 1*, r. This spring is preferably flat while spring 8, s, of the dog a, 12-, is coiled.
The operation of my improved tool will be readily understood by those skilledv in the art. One end of the box-strapping is placed under the gripping deviceA and the other end under the gripping device B, facing each other; By means of the handle G, the drum. F, is turned partly round thus winding up the cable D, and drawing the two gripping devices A, B, to each other, the two strap ends thus overlapping. Step by step this process goes on till the bOX'. strapping has been brought to the desired tension. The overlapping ends are then SQ? I cured together in the usual Way by a suitable tion of tightening and securing the same, tool and the carriage E is drawn back to its and EL drum and cable mechanism whereby 10 initial position ready to receive another the tlghtening thereof is efiected.
